Description

Communication method and device

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a communication method and apparatus.

Background

As cellular communication technology evolves, the frequency spectrum used is wider and the number of antennas of the network device is larger and the power consumption of the network device is higher, so that "low carbon" is receiving more and more attention in the communication network.

At present, the purpose of saving the power consumption of the network equipment can be achieved by turning off the antenna of the network equipment. Turning off the antenna may also be understood as turning off the physical antenna port. Antenna turn-off may last from tens to hundreds of milliseconds. When part of the antennas of the network device are turned off, the number of antennas used to transmit the reference signal may be reduced, and thus the logical ports of the reference signal may be changed.

Taking the channel state information reference signal (CHANNEL STATE information-REFERENCE SIGNAL, CSI-RS) as an example, in the case that the network device turns off the antenna, the network device needs to indicate reporting configuration of channel state information (CHANNEL STATE information, CSI) for the terminal, so as to ensure that the terminal measures and reports accurate CSI.

In another example, L reporting configurations correspond to H PUCCH resources, L > H, i.e. there are different reporting configurations corresponding to the same PUCCH resource.

A terminal may also be referred to as a terminal device, user Equipment (UE), mobile station, mobile terminal, etc. The terminal may be widely applied to various scenes, for example, device-to-device (D2D), vehicle-to-device (vehicle to everything, V2X) communication, machine-type communication (MTC), internet of things (internet of things, IOT), virtual reality, augmented reality, industrial control, autopilot, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, and the like. The terminal can be a mobile phone, a tablet personal computer, a computer with a wireless receiving and transmitting function, a wearable device, a vehicle, an unmanned aerial vehicle, a helicopter, an airplane, a ship, a robot, a mechanical arm, intelligent household equipment and the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal.

The network devices and terminals may be fixed in location or may be mobile. Network devices and terminals may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; the device can be deployed on the water surface; but also on aircraft, balloons and satellites. The embodiment of the application does not limit the application scene of the network equipment and the terminal.

The roles of network devices and terminals may be relative, e.g., helicopter or drone 120i in fig. 1 may be configured as a mobile network device, with drone 120i being a network device for those terminals 120j that access radio access network 100 through 120 i; but for network device 110a 120i is a terminal, i.e., communication between 110a and 120i is via a wireless air interface protocol. Of course, communication between 110a and 120i may also be performed via an interface protocol between network devices, in which case 120i is also a network device with respect to 110 a. Thus, both the network device and the terminal may be collectively referred to as a communication apparatus, 110a and 110b in fig. 1 may be referred to as a communication apparatus having a network device function, and 120a-120j in fig. 1 may be referred to as a communication apparatus having a terminal function.

Communication can be carried out between the network equipment and the terminal, between the network equipment and between the terminal and the terminal through the authorized spectrum, communication can be carried out through the unlicensed spectrum, and communication can also be carried out through the authorized spectrum and the unlicensed spectrum at the same time; communication can be performed through a frequency spectrum of 6 gigahertz (GHz) or less, communication can be performed through a frequency spectrum of 6GHz or more, and communication can be performed using a frequency spectrum of 6GHz or less and a frequency spectrum of 6GHz or more simultaneously. The embodiment of the application does not limit the spectrum resources used by the wireless communication.

In the embodiment of the present application, the functions of the network device may be performed by modules (such as chips) in the network device, or may be performed by a control subsystem including the functions of the network device. The control subsystem including the network device function may be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal may be performed by a module (e.g., a chip or a modem) in the terminal, or by a device including the functions of the terminal.

In the embodiment of the application, the network equipment sends a downlink signal or downlink information to the terminal, and the downlink information is borne on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order for a terminal to communicate with a base station, it is necessary to establish a radio connection with a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the serving cell of the terminal. The terminal may also be interfered by signals from neighboring cells when communicating with the serving cell.

It should be understood that in the embodiment of the present application, a physical downlink shared channel (physical downlink SHARED CHANNEL, PDSCH), a physical downlink control channel (physical downlink control channel, PDCCH), a physical uplink control channel (physical uplink control channel, PUCCH) and a Physical Uplink Shared Channel (PUSCH) are merely used as examples of a downlink data channel, a downlink control channel, an uplink control channel and an uplink data channel, respectively, and the data channel and the control channel may have different names in different systems and different scenarios, and the embodiment of the present application is not limited thereto.

In the following, some terms in the embodiments of the present application are explained for easy understanding by those skilled in the art.

(1) Transmitting channel (transmitter, TX)

A Radio Frequency (RF) transmit channel is simply referred to as a transmit channel. One transmit channel corresponds to one physical antenna port. The transmit path may receive baseband signals from the baseband chip, radio-frequency process (e.g., up-convert, amplify, and filter) the baseband signals to obtain radio-frequency signals, and ultimately radiate the radio-frequency signals into space through the antenna. In particular, the transmit channel may include one or more of antenna switches, antenna tuners, power Amplifiers (PA), mixers (mixer), local Oscillators (LO), filters (filter), etc., which may be integrated into one or more chips as desired. The antenna may also sometimes be considered part of the transmit channel. In embodiments of the present application, transmit antenna off may also be referred to as transmit channel off.

(2) Antenna port (port)

The antenna ports may also be abbreviated as ports. Unless specifically stated, antenna ports in embodiments of the present application all refer to logical antenna ports, not physical antenna ports. One antenna port may be associated with one or more transmit channels. The signal on each antenna port is transmitted through the one or more transmit channels associated therewith. When one antenna port is associated with a plurality of transmitting channels, signals on the antenna port are weighted by weighting coefficients and then transmitted through the plurality of transmitting channels associated with the antenna port. It is also understood that a plurality of physical antennas are weighted by weighting coefficients to form a logical antenna. The weighting coefficients may be complex or real, and the weighting coefficients on different physical antennas may be the same or different. Each antenna port has a corresponding time-frequency resource and reference signal. The time-frequency resources corresponding to different antenna ports may be the same or different. The reference signal transmitted by the network device through the antenna port a may be used by the terminal to estimate characteristics of a wireless channel from the antenna port a to the terminal, where the characteristics of the wireless channel may be used by the terminal to estimate a physical channel transmitted through the antenna port a, or to determine information such as modulation order, code rate, etc. during data transmission. One reference signal may correspond to one or more antenna ports, and it is also understood that one reference signal may be transmitted through one or more antenna ports.

(3) Reference signal

The reference signal is a known signal provided by the transmitting end to the receiving end for channel estimation or channel sounding. The reference signal may be used for channel measurement, interference measurement, etc., for example, the terminal obtains the channel state by measuring parameters such as reference signal received quality (REFERENCE SIGNAL RECEIVING quality, RSRQ), signal-to-noise ratio (SNR), interference-and-noise ratio (signal to interference plus noise ratio, SINR), channel quality indication (channel quality indicator, CQI), precoding matrix indication (precoding matrix indicator, PMI), etc.

(4) Reference signal resource

The reference signal resources may specifically include at least one of time-frequency resources, antenna ports, power resources, and scrambling codes of the reference signal. The network device may transmit reference signals based on the reference signal resources and the terminal may receive reference signals based on the reference signal resources. In the embodiment of the present application, the one or more antenna ports corresponding to the reference signal resource may also be understood as one or more antenna ports included in the reference signal resource.

Specifically, the reference signal involved in the embodiment of the present application may be CSI-RS or synchronization signal and physical broadcast channel block (SSB). Correspondingly, the reference signal resource may be a CSI-RS resource or an SSB resource.

(5)CSI

In the process that the wireless signal reaches the receiving end from the transmitting end through the wireless channel, the wireless signal can be subjected to scattering, reflection and energy attenuation along with the distance, so that fading is generated; in addition, the wireless signal may also be interfered by other signals at the receiving end, thereby affecting the reception of the wireless signal. The CSI is used to characterize a wireless channel and may include at least one of CQI, PMI, CSI-RS resource indication (CSI-RS resource indicator, CRI), synchronization signal/physical broadcast channel block resource indication (synchronization signal/physical broadcast channel block resource indicator, SSBRI), layer Indicator (LI), rank Indicator (RI), L1-RSRP, and L1-SINR. CSI may be transmitted by a terminal to a network device through PUCCH or PUSCH.

(6) CSI configuration

Current CSI configurations include CSI reporting configuration (CSI-ReportConfig) and CSI resource configuration (CSI-ResourceConfig). The CSI-ReportConfig is mainly used for configuring parameters related to reporting of channel states, such as reporting types, reported measurement indexes, and the like. The CSI-ResourceConfig is used to configure related information of the reference signal resource, such as time-frequency resource, antenna port, power resource or scrambling code of the reference signal.

In the present application, the CSI reporting configuration may be replaced with the CSI reporting configuration.

The fields included in CSI-ReportConfig and CSI-ResourceConfig are briefly described below, respectively.

CSI-ReportConfig may include one or more of the following fields:

CSI reporting configuration identity (CSI-ReportConfigId): for marking a CSI reporting configuration;

Channel measurement resources (resourcesForChannelMeasurement): CSI-RS resources for configuring channel measurements, associated to resource configuration by CSI-ResourceConfigId, for example, resourcesForChannelMeasurement may carry an identification of CSI-ResourceConfig for channel measurements (CSI-ResourceConfigId);

Interference measurement resources (CSI-IM-RessourcesForInterference) for configuring resources of CSI-RS for interference measurement, associated to resource configuration through CSI-ResourceConfigId;

Reporting configuration type (reportConfigType): reporting types used for configuring the CSI can be divided into periodic reporting, semi-persistent reporting, aperiodic reporting and the like; semi-persistent reporting may also be described as semi-persistent reporting.

Reporting amount (reportQuantity): this field is used to indicate the reporting amount of CSI. The reporting amount of CSI may include a reference signal resource identity CRI, RI, PMI, CQI, etc.

CSI-ResourceConfig may indicate one or more non-zero power (none zero powe, NZP) CSI-RS resource sets, or may indicate one or more CSI interference measurement (CSI-IM) resource sets, or may indicate one or more SSB resource sets. One set of NZP-CSI-RS resources may comprise one or more NZP-CSI-RS resources, one set of CSI-IM resources may comprise one or more CSI-IM resources, and one set of SSB resources may comprise one or more SSB resources.

Specifically, CSI-ResourceConfig may include one or more of the following fields:

CSI resource configuration identity (CSI-ResourceConfigId): a resource configuration for identifying one CSI;

CSI resource set list (CSI-RS-ResourceSetList): this field is used to configure a queue of resource sets, where the resource sets may include a set of reference signal resources for channel measurements. CSI-RS-ResourceSetList may be associated to a configuration of a NZP-CSI-RS resource set (NZP-CSI-RS-resource set) through NZP-CSI-RS-ResourceSetId. One or more NZP-CSI-RS-resources are included in the NZP-CSI-RS-resources.

Resource type (resourceType): the type of the reference signal resource used for configuring the reference signal resource may be classified into a periodic resource, a semi-persistent resource, a non-periodic resource, and the like. Semi-persistent resources may also be described as semi-persistent resources.

Codebook configuration (codebookConfig): for configuring a subset of a multiple-input multiple-output (multi input multi output, MIMO) codebook and codebook-related information.

It should be appreciated that CSI-ReportConfig or CSI-ResourceConfig may also include other fields, which are not listed here.

In the present application, the CSI-RS resource may be equivalent to NZP-CSI-RS resource for channel measurement.

The network device may configure or reconfigure CSI reporting configuration (CSI-ReportConfig) and CSI-RS resource configuration (CSI-ResourceConfig) for the terminal through radio resource control (radio resource control, RRC) signaling. The network device may indicate CSI report configuration through RRC information ELEMENT CSI-ReportConfig included in the RRC signaling. The association of CSI measurement and CSI reporting is changed through RRC signaling.

(7) CSI processing unit (CSI processing unit CPU)

The terminal performs CSI measurement, and needs to occupy a certain storage resource. The number of CPUs is used in the 3GPP protocol to characterize the resources required by the terminal to process the CSI. The terminal will report to the network device the number of CPUs the terminal can support. For example, the terminal 1 informs the base station that the maximum number of CPUs supported by it is 10; the terminal 2 informs the base station that it supports a maximum number of CPUs of 15. The maximum number of CPUs supported herein refers to the number of CPUs supported simultaneously, and may be the number of CPUs supported simultaneously by one carrier or the number of CPUs supported simultaneously by all carriers. For example, the terminal only supports one CPU, indicating that at the same time, the terminal only has one CPU for CSI processing.

(8) Antenna turn-off

Illustratively, antenna shut-off may include two types: the first type, antenna turn-off affects the antenna ports, when the antenna turn-off occurs, the number of the antenna ports of the CSI-RS can change; the second type, antenna turn-off, does not affect the antenna ports, i.e., when antenna turn-off occurs, the antenna ports of the CSI-RS do not change.

(9) Semi-persistent CSI reporting configuration activation and deactivation

The semi-persistent CSI reporting configuration refers to CSI reporting configuration with a reporting configuration type of semi-persistent reporting. The semi-persistent CSI reporting may be understood as that after receiving an activation signaling for the semi-persistent CSI reporting configuration, the terminal may periodically report CSI according to the semi-persistent CSI reporting configuration, and after receiving a deactivation signaling for the semi-persistent CSI reporting configuration, the terminal may stop reporting CSI.

In NR, the semi-persistent CSI reporting configuration may include a semi-persistent CSI reporting configuration that transmits CSI on a PUCCH resource and a semi-persistent CSI reporting configuration that transmits CSI on a PUSCH.

For the case of transmitting CSI on PUCCH, semi-persistent CSI reporting configuration is activated or deactivated by a medium access control unit (medium access control control ELEMENT MAC CE). The format of the MAC CE is shown in fig. 2. The MAC CE includes 2 bytes, wherein the first byte includes two information fields indicating a serving cell and an upstream bandwidth part (BWP), respectively. Illustratively, in fig. 2, the first byte includes a serving cell identification (SERVING CELL ID) and a BWP identification (BWP ID).

The 4 bits in the second byte are used to activate or deactivate the semi-persistent CSI reporting configuration. The 4 bits respectively correspond to 4 semi-continuous CSI reporting configurations, and for any one bit of the 4 bits, when the value of the bit is 0, the semi-continuous CSI reporting configuration corresponding to the bit is indicated to be deactivated, and when the value of the bit is 1, the semi-continuous CSI reporting configuration corresponding to the bit is indicated to be activated. Wherein the other 4 bits in the second byte are reserved bits. Illustratively, in fig. 2, the last 4 bits S ₀ to S ₃ in the second byte are used to indicate that the 4 semi-persistent CSI reporting configurations are active or inactive. R in fig. 2 represents a reserved bit.

For the case of transmitting CSI on PUSCH, semi-persistent CSI reporting configuration is activated or deactivated by downlink control information (downlink control indicator, DCI). Wherein, there is an information field in the DCI, the information field is a CSI request field (CSI request field), the information field indicates a trigger state (TRIGGER STATE), the trigger state indicates a semi-persistent CSI reporting configuration, for example, the information field includes an identifier (CSI-ReportConfigId) of the semi-persistent CSI configuration.

The terminal determines that the semi-persistent CSI indicated by the information field is configured to be activated or deactivated according to the special field in the DCI. It should be further noted that, for the semi-persistent CSI reporting configuration, in the case where one semi-persistent CSI reporting configuration has been activated, the terminal does not expect to receive DCI activating the same semi-persistent CSI reporting configuration.

Wherein the dedicated field for indicating to activate the semi-persistent CSI reporting configuration comprises a hybrid automatic repeat request (hybrid automatic repeat request, HARQ) process value (HARQ process number) and a redundancy version (redundany version), and the dedicated field for indicating to deactivate the semi-persistent CSI reporting configuration comprises a HARQ process value, a redundancy version, a modulation and coding scheme (modulation and coding scheme, MCS) and a resource allocation (resource block assignment).

To sum up, some configurations in the active or inactive semi-persistent CSI configuration, for example, the trigger state in the DCI, are currently not supported, and only activation or deactivation of a single semi-persistent CSI reporting configuration can be indicated. As another example, 4 bits in the MAC CE can also indicate activation or deactivation only for a single semi-persistent CSI reporting configuration.

In addition, taking the activated semi-persistent CSI reporting configuration triggered by the MAC CE as an example, the semi-persistent CSI reporting configuration corresponds to one PUCCH resource, that is, the X reporting configurations and the Y reporting configurations in the semi-persistent CSI reporting configuration correspond to the same PUCCH resource, so it is desirable to implement the switching of reporting contents by reporting X CSI according to the X configurations and reporting Y CSI according to the Y configurations, where the MAC CE needs to be frequently sent.

For example, the semi-persistent reporting configuration includes 4 configurations, it is desirable to implement reporting CSI according to configuration 1 and reporting CSI according to configuration 4, it is necessary to activate configuration 1 through a MAC CE indication, deactivate configuration 1 through a MAC CE indication after receiving reporting CSI according to configuration 1 from the terminal, activate configuration 4, deactivate configuration 4 through a MAC CE indication after receiving reporting CSI according to configuration 4 from the terminal, activate configuration 1 after receiving reporting CSI according to configuration 1 from the terminal, deactivate configuration 1 through a MAC CE indication, activate configuration 4, and so on, thus resulting in a large signaling overhead.

For the case that the DCI triggers to activate the semi-persistent CSI reporting configuration, it is currently not supported to receive DCI activating one semi-persistent CSI reporting configuration after activating the same semi-persistent CSI reporting configuration. Therefore, if it is desired to report X pieces of CSI according to X reporting configurations and report X pieces of CSI according to Y reporting configurations, the DCI needs to be frequently sent to switch the reporting contents.

For example, the semi-persistent reporting configuration includes 4 configurations, it is desirable to report CSI according to the 1 st configuration, and the 4 th configuration, and it is necessary to activate the 1 st configuration first through DCI, deactivate the 1 st configuration through DCI indication after the CSI is reported according to the 1 st configuration is received from the terminal, activate the 4 th configuration through DCI indication, deactivate the 4 th configuration through DCI indication after the CSI is reported according to the 4 th configuration is received from the terminal, activate the 1 st configuration through DCI indication after the CSI is reported according to the 1 st configuration is received from the terminal, activate the 4 th configuration through DCI indication, and so on, thus resulting in a large signaling overhead.

Based on the network system architecture shown in fig. 1 and the description of the related art, several possible communication methods are provided in the embodiments of the present application, and the implementation subject of each communication method is described by taking a network device and a terminal as an example. For example, the network device may be the access network device 110a or the access network device 110b of fig. 1. The terminal may be any of the terminals 120 previously described with respect to fig. 1. Furthermore, it should be understood that the network device may also be replaced by a communication apparatus having a network device function or by a chip, a unit or a module inside the communication apparatus having a network device function. The terminal may also be replaced by a communication device with terminal functionality or by a chip, unit or module inside the communication device with terminal functionality.

In the present application, the CSI reporting configuration information may also be referred to as CSI reporting configuration information, and the CSI reporting configuration information may be simply referred to as CSI reporting configuration, or CSI reporting configuration. The CSI reporting configuration information may include a plurality of reporting configurations, and may be described as CSI reporting configuration information may include a plurality of sub-configurations. In addition, the CSI reporting configuration information may include a plurality of reporting configurations, or it may be understood that the CSI reporting configuration information is associated with the plurality of reporting configurations, and the CSI reporting configuration information has a correspondence relationship with the plurality of reporting configurations, for example, the CSI reporting configuration information may include indexes corresponding to the plurality of reporting configurations respectively. In general, the plurality of reporting configurations are different from each other. Optionally, the plurality of reporting configurations may further correspond to a first parameter, and the first parameter may be a parameter for indicating a channel quality information table, where the CSI reporting configuration information includes the first parameter. It should be understood that, in the CSI reporting configuration information, multiple independent reporting configurations may be included, and may also include some common parameters, such as the first parameter, where the multiple independent reporting configurations all correspond to the common first parameter. When calculating the CSI corresponding to one reporting configuration (sub-configuration), the terminal equipment calculates the CSI according to the indication information and the first parameter included in the reporting configuration, and when calculating the CSI corresponding to the other reporting configuration, the terminal calculates the CSI according to the indication information and the first parameter included in the other reporting configuration.

The first reporting configuration is illustratively any one reporting configuration of the first CSI reporting configuration information, and the first CSI reporting configuration information is any one CSI reporting configuration information. The first CSI reporting configuration information is associated with a first CSI-RS resource set, where the first CSI-RS resource set includes at least one CSI-RS resource, for example, the first CSI-RS resource set may be a NZP-CSI-RS resource set, and the at least one CSI-RS resource is a NZP-CSI-RS resource.

Optionally, the first reporting configuration may include indication information, where the indication information is used to indicate CSI-RS resources associated with the first reporting configuration, and the CSI-RS resources associated with the first reporting configuration belong to the first CSI-RS resource set. The CSI-RS resources associated with the first reporting configuration, that is, measurement resources required by the terminal to generate CSI corresponding to the first reporting configuration. Or the indication information is described as indicating the reference signal resource corresponding to the first reporting configuration or the measurement resource corresponding to the first configuration.

In addition, the second reporting configuration is one reporting configuration in the first CSI reporting configuration information, and the second reporting configuration is different from the first reporting configuration, and may also include indication information, where the indication information is used to indicate CSI-RS resources associated with the second reporting configuration. The CSI-RS resources associated with the second reporting configuration are different from the CSI-RS resources associated with the first reporting configuration. The CSI-RS resources associated with the second reporting configuration also belong to the first CSI-RS resource set. Therefore, the CSI-RS resources associated with different reporting configurations in the first CSI reporting configuration information are different, and the CSI-RS resources associated with different reporting configurations are different and belong to the first CSI-RS resource set.

In one possible implementation, the indication information directly indicates one or more CSI-RS resources. One or more CSI-RS resources belong to a first CSI-RS set. Further, the terminal may measure CSI-RS received on the corresponding resources according to one or more CSI-RS resources indicated by the indication information, so as to determine CSI corresponding to the first reporting configuration.

In another possible implementation manner, the indication information indicates P ports, where the P ports are included in Q ports, and the Q ports are ports of a first channel state information reference signal resource, where the first channel state information reference signal resource is included in a first channel state information reference signal resource set, and resources corresponding to the P ports in the first channel state information reference signal resource are second channel state information reference signals, where the second channel state information reference signal resource is included in a channel state information reference signal resource associated with the first reporting configuration. That is, the terminal device measures according to the CSI-RS received at the second channel state information reference signal resource, and further determines CSI corresponding to the first reporting configuration.

Or described as indicating that the first reporting configuration is associated with a subset of ports. The port subset may be applicable to at least one CSI-RS resource in the first CSI-RS resource set, and the port subset may be used to determine resources corresponding to a portion of ports in the CSI-RS resources in the first CSI-RS resource set.

In an exemplary embodiment, the terminal may determine, according to the indication information, resources corresponding to part of ports in at least one CSI-RS resource in the first CSI-RS resource set, and measure CSI-RS received from the corresponding resources, so as to determine CSI corresponding to the first reporting configuration.

The indication information indicates P ports, and takes the case that the X CSI-RS resources correspond to Q ports as an example, and P is smaller than or equal to Q, X, P, and Q are positive integers, so that the indication information indicates P ports, that is, indicates that the X CSI-RS resources respectively correspond to the resources corresponding to P ports in the Q ports, and the terminal measures according to CSI-RS received by the resources, thereby determining CSI corresponding to the first reporting configuration. The P ports in the Q ports corresponding to the ith CSI-RS resource refer to P ports with indexes of 0 to P-1 in the Q ports corresponding to the ith CSI-RS resource, wherein the ith CSI-RS resource is any one of X CSI-RS resources, and i is less than or equal to X. In addition, P ports may be determined in order from small to large according to even (or odd) numbers in the indexes of the ports, or P ports may be determined in preset intervals according to the order from small to large in the indexes of the ports. The application does not limit the specific rule for determining P ports, and the rule can be agreed through a protocol or the network equipment can be configured for the terminal in advance.

Illustratively, P may be any one of 2, 4, 8, 16 and Q may be 32.

For example, when the value of P is 16 and the value of q is 32 and x=2, the terminal determines, according to the indication information, that the 1 st CSI-RS resource corresponds to 16 ports with indexes 0 to 15 out of the 32 ports and that the 2 nd CSI-RS resource corresponds to 16 ports with indexes 0 to 15 out of the 32 ports, receives the CSI-RS on the resources corresponding to the 16 ports with indexes 0 to 15 out of the 1 st CSI-RS resource corresponds to the 16 ports with indexes 0 to 15 and that the 2 nd CSI-RS resource corresponds to the 16 ports with indexes 0 to 15, and determines the CSI corresponding to the first reporting configuration.

Optionally, the first reporting configuration may include indication information, where the indication information indicates a first power offset value, where the first power offset value is a ratio assumption of energy (EPRE) on each resource unit in the PDSCH relative to EPRE of a first channel state information reference signal resource, where the first channel state information reference signal resource is a measurement resource required for configuring the corresponding CSI for the first reporting. It should be appreciated that the indication information indicates the first power offset value, either directly or indirectly, such as an index indicating the first power offset value.

Fig. 3 schematically illustrates a possible flow chart of a communication method according to an embodiment of the present application. As shown in fig. 3, the method includes:

step 300: the network device sends a first message. Correspondingly, the terminal receives the first message.

The first message is used for activating N reporting configurations in the first CSI reporting configuration information.

The first CSI reporting configuration information includes L reporting configurations, where the L reporting configurations include N reporting configurations, N is equal to or less than L, N, and L are positive integers, and the first CSI reporting configuration information further includes a reporting configuration type, where the reporting configuration type includes semi-persistent reporting or aperiodic reporting. I.e. the first CSI reporting configuration information is semi-persistent CSI reporting configuration information or aperiodic reporting configuration information.

The following description will take the first CSI reporting configuration information as the semi-persistent CSI reporting configuration information as an example.

The first CSI reporting configuration information is one of a plurality of CSI reporting configuration information that can be activated or deactivated by the network device. The multiple CSI reporting configuration information may be configured in advance for the terminal through RRC signaling.

The first message may be, for example, a MAC CE. Specifically, the first message may be a MAC CE (SP CSI reporting on PUCCH Activation/Deactivation MAC CE) for activating or deactivating semi-persistent CSI reporting transmitted on the PUCCH.

In one possible implementation, the first message includes first information and second information, the first information is used for indicating an activation state of the first CSI reporting configuration information, and the second information is used for indicating N reporting configurations.

Illustratively, the first message includes a plurality of bits, each bit for activating or deactivating one CSI reporting configuration information. Corresponding to 1 bit of the first CSI reporting configuration information, if the value of the 1 bit is 0, it indicates that the first CSI reporting configuration information is in a deactivated state, or describes that the first CSI reporting configuration information is deactivated, and it can be understood that at this time, each reporting configuration in the first CSI reporting configuration information is deactivated.

The 1 bit has a value of 1, which indicates that the first CSI reporting configuration information is in an active state, or is described as that the first CSI reporting configuration information is activated.

The following describes possible implementation manners of the second information indicating N reporting configurations:

Mode 1: the second information includes L bits, where the L bits correspond to the L reporting configurations one-to-one, and N bits in the L bits indicate that the N reporting configurations are activated, and remaining (L-N) bits in the L bits indicate that (L-N) reporting configurations other than the N reporting configurations in the L reporting configurations are not activated or deactivated.

The second information is illustratively in the form of a bit map. The bit map comprises L bits, and the L bits are in one-to-one correspondence with L reporting configurations. For example, for any one bit of the L bits, when the value of the bit is 0, it indicates that the reporting configuration corresponding to the bit is not activated, and when the value of the bit is 1, it indicates that the reporting configuration corresponding to the bit is activated.

Mode 2: the second information comprises S bits, the S bits are in one-to-one correspondence with S reporting configuration groups, the second information indicates K reporting configuration groups in the S reporting configuration groups, and the K reporting configuration groups comprise N reporting configurations. S is an integer greater than 1, K is a positive integer, and K is less than or equal to S. Wherein K bits of the S bits indicate that the K reporting configuration groups are activated, and the remaining (S-K) bits of the S bits indicate that (S-K) reporting configuration groups other than the K reporting configuration groups of the S reporting configuration groups are not activated or deactivated.

The S reporting configuration groups are illustratively configured by the network device for the terminal, e.g., the network device may configure the S reporting configuration groups for the terminal through RRC signaling or MAC CE, or the S reporting configuration groups are determined according to predefined rules. Optionally, the S reporting configuration groups are configured by the network device, which may be understood that the network device configures S reporting configuration groups, and one or more reporting configurations included in each reporting configuration group, for example, the network device indicates s=2 reporting configuration groups, with numbers 1-2, where the reporting configuration group 1 includes 1 reporting configuration, and the reporting configuration group 2 includes 2 reporting configurations. Or the S reporting configuration groups are configured by the network device, which can be understood that the network device configures the corresponding relationship between each bit in the S bits and one or more reporting configurations, and one or more reporting configurations corresponding to the same bit are configured as one reporting configuration group. For example, there are l=3 reporting configurations, s=2 bits, the first bit of the network device configuration s=2 bits corresponds to the first reporting configuration of the l=3 reporting configurations (forming a reporting configuration group), and the second bit of the network configuration s=2 bits corresponds to the second reporting configuration of the l=3 reporting configurations and the third reporting configuration (forming a reporting configuration group).

It will be appreciated that the present application is not limited to a particular manner of determining the reporting configuration set. Each reporting configuration group comprises at least one reporting configuration, the number of the reporting configurations included in different reporting configuration groups can be the same or different, and the reporting configurations included in different reporting configuration groups can be overlapped or completely different. The L reporting configurations are reporting configurations included in the S reporting configuration groups. Or describing that the reporting configurations included in the S reporting configuration groups come from L reporting configurations. Or the L reporting configurations are described as reporting configurations included in the S reporting configuration groups.

In one possible implementation, the same number of reporting configurations may be used as one reporting configuration group according to the order of the indexes of the L reporting configurations.

For example, the first CSI reporting configuration information includes 8 reporting configurations, the index of the 8 reporting configurations is 0 to 7, each reporting configuration group includes 2 reporting configurations, and then 4 reporting configuration groups may be determined altogether, the reporting configuration group 1 includes reporting configuration with index 0 and reporting configuration with index 1, the reporting configuration group 2 includes reporting configuration with index 2 and reporting configuration with index 3, the reporting configuration group 3 includes reporting configuration with index 4 and reporting configuration with index 5, and the reporting configuration group 4 includes reporting configuration with index 6 and reporting configuration with index 7.

The second information is illustratively in the form of a bit map. The bitmap includes S bits, where the S bits correspond to the S reporting configuration groups one-to-one. For example, for any one of the S bits, when the value of the bit is 0, the reporting configuration group corresponding to the bit is not activated, and when the value of the bit is 1, the reporting configuration group corresponding to the bit is activated.

The second information indicates K reporting configuration groups of the S reporting configuration groups, and may be further described as that the second information indicates that K reporting configuration groups of the S reporting configuration groups are activated, or that K reporting configuration groups of the S reporting configuration groups are activated.

For example, if k=1, the reporting configuration group includes N reporting configurations. Or the report configuration group is described as being formed by N report configurations.

If K is greater than 1, the reporting configuration set formed by the K reporting configuration groups comprises N reporting configurations. For example, n=4, k=2, and the 2 reporting configuration groups indicated by the second information may each include 2 reporting configurations, or 1 reporting configuration group includes 1 reporting configuration, and another reporting configuration group includes 3 reporting configurations.

In mode 3, the second information indicates an index of a first reporting configuration group, where the first reporting configuration group includes N reporting configurations, and the first reporting configuration group is one of S reporting configuration groups.

For S reporting configuration groups, reference may be made to the description related to the above manner 2, which is not repeated here.

In addition, in one possible implementation manner, the second indication information may further include indexes of a plurality of reporting configuration groups, and the reporting configuration set formed by the plurality of reporting configuration groups indicated by the indexes of the plurality of reporting configuration groups includes N reporting configurations.

In one possible implementation manner, the second indication information may further include an index, where the index corresponds to a plurality of reporting configuration groups, and a reporting configuration set formed by the plurality of reporting configuration groups includes N reporting configurations.

Possible forms of bytes (or bits) of the first information and the second information in the first message are described below with reference to the accompanying drawings:

In one possible implementation, the first information and the second information are carried in the same byte of the first message.

Illustratively, where the first information and the second information are carried in the same byte of the first message, the second information is one or more of the first B bits in the second byte of the first message, the first information is the last a bits in the second byte of the first message, where a+b=8, and a, B are positive integers. The number of the one or more bits may be equal to L.

For example, as shown in fig. 2, the last 4 bits in the second byte in the first message are used to carry the first information, one or more of the 4 reserved bits in the second byte are used to carry the second information, or the first 4 bits in the second byte are described as being used to carry the second information.

In another possible implementation, the first information and the second information are carried in different bytes of the first message.

In the case where the first information and the second information are carried in different bytes of the first message, the second information is one or more bits in other bytes than the first byte and the second byte in the first message, the first information is the last a bits of the second byte in the first message, and a is a positive integer.

For example, the MAC CE may be newly added with at least one byte, for example, the following description will take only a new byte as an example, and since the MAC CE already includes 2 bytes, the new added byte may be also referred to as a third byte in the MAC CE. Wherein one or more bits of the new byte may be used to carry the second information.

For example, as shown in fig. 4, the third byte in the MAC CE may be a new byte, and the last 6 bits in the new byte may be used to carry the second information. Here, the description is given by taking 6 as an example, and the present application is not limited thereto.

In addition, the two modes may be combined with each other, for example, the second information is carried by A1 bits in the second byte and A2 bits in the third byte, where A1 and A2 are positive integers, where A1 is less than or equal to 4 and A2 is less than or equal to 8.

The first message may be DCI, for example. Specifically, the first message may be DCI scrambled by the SP-CSI-RNTI. The first message indicates a first trigger state, where the first trigger state indicates an index of the first CSI reporting configuration and N reporting configurations in the first CSI reporting configuration information (e.g., indicates an index of the N reporting configurations in the first CSI reporting configuration information).

Step 310: the terminal sends N pieces of CSI according to the N pieces of reporting configuration, and the N pieces of CSI are in one-to-one correspondence with the N pieces of reporting configuration.

For example, the terminal may determine N CSI according to N reporting configurations, that is, the terminal may determine a corresponding CSI according to each reporting configuration of the N reporting configurations.

By adopting the method, the network equipment can activate partial reporting configuration in the CSI reporting configuration information.

In addition, the network device may deactivate a part of the reporting configuration in the CSI reporting configuration information, or the network device may activate a part of the reporting configuration in the CSI reporting configuration information and deactivate a part of the reporting configuration in the CSI reporting configuration information at the same time.

For example, for the above-described mode 1, N bits of the L bits in the second information indicate that N reporting configurations are activated, and the remaining (L-N) bits of the L bits indicate that (L-N) reporting configurations other than the N reporting configurations among the L reporting configurations are not activated or deactivated. When the N reporting configurations need to be deactivated, the N bits indicate that the N reporting configurations are deactivated, e.g., the N bit values are all set to 0. In addition, other reporting configurations may also be selected to be activated simultaneously.

For example, for the above manner 2, K bits of the S bits indicate that K reporting configuration groups are activated, and the remaining (S-K) bits of the S bits indicate that (S-K) reporting configuration groups other than the above K reporting configuration groups of the S reporting configuration groups are not activated or deactivated. When the K reporting configuration groups need to be deactivated, the K bits indicate that the K reporting configuration groups are deactivated, for example, the K bits are all set to 0. In addition, other reporting configuration groups may also be activated simultaneously.

The following describes how PUCCH resources for reporting CSI are configured:

in one possible implementation, the L reporting configurations correspond to H PUCCH resources, where H is an integer greater than 1 and H is less than or equal to L. It may be understood that the L reporting configurations correspond to H PUCCH resources, which may be described as that the L reporting configurations are associated with H PUCCH resources, where the H PUCCH resources are used to report L CSI determined according to the L reporting configurations, or that the L reporting configurations correspond to L CSI and are sent on the H PUCCH resources.

Illustratively, the H PUCCH resources are different from each other.

In one possible implementation, the L reporting configurations are configured independently for PUCCH resources corresponding to the respective reporting configurations.

Specifically, the L reporting configurations respectively correspond to the PUCCH resource independent configurations, and each reporting configuration in the L reporting configurations may include configuration information for configuring the PUCCH resource, or each reporting configuration in the L reporting configurations includes an index of the PUCCH resource.

In an example, the L reporting configurations correspond to L PUCCH resources, where l=h, and the L PUCCH resources are different from each other.

In another example, the L reporting configurations correspond to H PUCCH resources, L > H, that is, the same PUCCH resource exists in the L PUCCH resources independently configured for the L reporting configurations, or it is described that different reporting configurations exist corresponding to the same PUCCH resource.

By adopting the mode, the PUCCH resources are configured with single reporting configuration as granularity. The terminal obtains L reporting configurations corresponding to the PUCCH resource configuration information, i.e. L PUCCH resource configuration information, where the L PUCCH resource configuration information may be completely different, or may have a part of the same, but not completely the same. The terminal needs to determine whether the L reporting configurations are different from each other or whether there are reporting configurations using the same PUCCH resource. For example, if the terminal determines that the N1 reporting configurations correspond to the same PUCCH resource (hereinafter, referred to as PUCCH resource 1), the terminal multiplexes the N1 CSI determined according to the N1 reporting configurations onto PUCCH resource 1 and transmits the multiplexed CSI.

In another possible implementation manner, the PUCCH resources corresponding to the S reporting configuration groups respectively are configured independently.

Specifically, the PUCCH resources corresponding to the S reporting configuration groups are configured independently, and each reporting configuration group in the S reporting configuration groups may include configuration information for configuring the PUCCH resources, or each reporting configuration group in the S reporting configuration groups includes an index of the PUCCH resources.

In an example, the S reporting configuration groups correspond to S PUCCH resources, which are different from each other, and h=s.

In another example, the S reporting configuration groups correspond to H PUCCH resources, S > H, that is, the same PUCCH resource exists in the S PUCCH resources configured independently for the S reporting configuration groups, or it is described that there are different reporting configuration groups corresponding to the same PUCCH resource.

By adopting the mode, the PUCCH resource is configured by taking a single reporting configuration group as granularity. The terminal obtains the S reporting configuration groups corresponding to the PUCCH resource configuration information respectively, that is, the S PUCCH resource configuration information, where the S PUCCH resource configuration information may be completely different, or may have a part of the same, but not completely the same. The terminal can directly determine that each reporting configuration in the same reporting configuration group corresponds to the same PUCCH resource. For example, the terminal determines N2 reporting configurations included in the jth reporting configuration group, where the jth reporting configuration group corresponds to PUCCH resource 2, and multiplexes N2 CSI determined according to the N2 reporting configurations onto PUCCH resource 2 for transmission, where the jth reporting configuration group is one of S reporting configuration groups, and j is a positive integer.

Further, in the case that the N reporting configurations correspond to W1 PUCCH resources, N CSI are periodically transmitted on the W1 PUCCH resources according to the N reporting configurations, where the H PUCCH resources include W1 PUCCH resources, and W1 is a positive integer. It may be understood that, after the first message activates N reporting configurations in the first CSI reporting configuration information, the terminal may periodically send N CSI on W1 PUCCH resources according to the N reporting configurations. If the N reporting configurations are deactivated, the terminal does not send the N CSI determined according to the N reporting configurations.

In one possible design, after receiving the first message, a second message is received, where the second message is used to activate M reporting configurations in the first CSI reporting configuration information, and M is a positive integer.

Under the condition that the M reporting configurations correspond to the W2 PUCCH resources, M pieces of CSI are periodically transmitted on the W2 PUCCH resources according to the M reporting configurations, the M pieces of channel state information are in one-to-one correspondence with the M reporting configurations, the H PUCCH resources comprise the W2 PUCCH resources, W2 is a positive integer, and the W2 PUCCH resources and the W1 PUCCH resources are different from each other.

It may be understood that after the second message activates M reporting configurations in the first CSI reporting configuration information, since W2 PUCCH resources and W1 PUCCH resources are different from each other, the terminal may periodically send M CSI on W2 PUCCH resources according to the M reporting configurations. That is, the second message does not affect the reporting of the N CSI, so that the network device does not need to frequently perform signaling switching for reporting the N CSI and reporting the M CSI, and signaling overhead caused by switching the reporting content through dynamic signaling can be avoided. If the M reporting configurations are deactivated, the terminal does not send the M CSI determined according to the M reporting configurations.

For example, in the case that the N reporting configurations correspond to the first PUCCH resource, the terminal periodically transmits N CSI on the first PUCCH resource according to the N reporting configurations, where the H PUCCH resources include the first PUCCH resource, w1=1. After receiving the first message, the terminal receives a second message, where the second message is used to activate M reporting configurations in the first CSI reporting configuration information. And under the condition that the M reporting configurations correspond to the second PUCCH resources, the terminal periodically transmits M pieces of CSI on the second PUCCH resources according to the M reporting configurations, the H PUCCH resources comprise the second PUCCH resources, W2=1, and the second PUCCH resources are different from the first PUCCH resources.

In another possible design, the first message is further configured to activate M reporting configurations in the first CSI reporting configuration information, where M is a positive integer. Illustratively, the first message may activate two reporting configuration groups in manner 2 described above, or the first message may carry the indices of two reporting configurations in manner 3 described above. One reporting configuration group comprises N reporting configurations, and the other reporting configuration group comprises M reporting configurations.

Similarly to the above possible design, in the case where the M reporting configurations correspond to W2 PUCCH resources, M channel state information is periodically transmitted on the W2 PUCCH resources according to the M reporting configurations, the M channel state information corresponds to the M reporting configurations one to one, the H PUCCH resources include W2 PUCCH resources, W2 is a positive integer, and the W2 PUCCH resources and the W1 PUCCH resources are different from each other.

It may be understood that, in the case that the first message also activates M reporting configurations in the first CSI reporting configuration information, since W2 PUCCH resources and W1 PUCCH resources are different from each other, the terminal may periodically transmit M CSI on W2 PUCCH resources according to the M reporting configurations. That is, the same signaling triggers the reporting of the N CSI and the M CSI, and the N CSI and the M CSI do not affect each other, so that the network device does not need to frequently perform signaling switching for reporting the N CSI and the M CSI, and signaling overhead caused by switching reporting contents through dynamic signaling can be avoided. If the M reporting configurations are deactivated, the terminal does not send the M CSI determined according to the M reporting configurations.

For example, in the case that the N reporting configurations correspond to the first PUCCH resource, the terminal periodically transmits N CSI on the first PUCCH resource according to the N reporting configurations, where the H PUCCH resources include the first PUCCH resource, w1=1. And when the first message is further used for activating M reporting configurations in the first CSI reporting configuration information and the M reporting configurations correspond to the second PUCCH resources, the terminal periodically transmits the M CSI on the second PUCCH resources according to the M reporting configurations, the H PUCCH resources comprise the second PUCCH resources, W2=1, and the second PUCCH resources are different from the first PUCCH resources.

Fig. 5 schematically illustrates a possible flow chart of another communication method according to an embodiment of the present application. As shown in fig. 5, the method includes:

Step 500: and the network equipment sends the second CSI reporting configuration information, and correspondingly, the terminal receives the second CSI reporting configuration information.

For example, the second CSI reporting configuration information includes L reporting configurations, where the L reporting configurations correspond to H PUCCH resources, H is an integer greater than 1, L is a positive integer, and H is equal to or less than L. The second CSI reporting configuration information further includes a reporting configuration type, where the reporting configuration type is periodic reporting or semi-persistent reporting.

Step 510: under the condition that N reporting configurations in the L reporting configurations correspond to W1 PUCCH resources, the terminal periodically transmits N CSI on the W1 PUCCH resources according to the N reporting configurations, the N CSI corresponds to the N reporting configurations one by one, the H PUCCH resources comprise W1 PUCCH resources, and W1 and N are positive integers.

For specific reference to the above related matters, details of how to configure the H PUCCH resources are not described herein.

For example, in the case that N reporting configurations in the L reporting configurations correspond to W1 PUCCH resources, if w1=1, the terminal periodically transmits N CSI on one PUCCH resource according to the N reporting configurations, that is, multiplexes the N CSI determined according to the N reporting configurations onto the PUCCH resource for transmission.

For example, in the case that N reporting configurations of the L reporting configurations correspond to W1 PUCCH resources, if W1 > 1, the terminal periodically transmits N CSI on the multiple PUCCH resources according to the N reporting configurations. In this case, the plurality of PUCCH resources, i.e., W1 PUCCH resources, may be different from each other.

It should also be appreciated that, in one possible implementation, in the case where the reporting configuration type of the second CSI reporting configuration is periodic reporting, the network device does not need extra signaling to trigger activation of the N reporting configurations.

In a possible implementation manner, in the case where the reporting configuration type of the second CSI reporting configuration is semi-persistent reporting, the network device further needs to trigger and activate N reporting configurations by using extra signaling, and the specific reference may be made to the activation manner in the embodiment shown in fig. 3, which is not described herein again.

Fig. 6 schematically illustrates a possible flow chart of another communication method according to an embodiment of the present application. The embodiment shown in fig. 6 is applied to a semi-persistent CSI reporting configuration for transmitting CSI on PUSCH. As shown in fig. 6, the method includes:

Step 600: the network device sends the third information, and the terminal receives the third information.

The third information is used for activating N reporting configurations in the first CSI reporting configuration information and scheduling the first PUSCH resource, wherein N is a positive integer; the first CSI reporting configuration information comprises a reporting configuration type, and the reporting configuration type is semi-persistent reporting.

Step 610: after transmitting the third information, the network device transmits fourth information. Accordingly, after receiving the third information, the terminal receives the fourth information.

Or it may be further described that, in the case that the first reporting configuration is activated, or N1 sub-configurations of the first reporting configuration are activated, the network device sends fourth information, and correspondingly, the terminal receives the fourth information.

The fourth information is used for activating M reporting configurations in the first CSI reporting configuration information and scheduling second PUSCH resources, M is a positive integer, and the second PUSCH resources are different from the first PUSCH resources.

Step 620: the terminal periodically transmits N pieces of CSI on the first PUSCH resource according to N pieces of reporting configuration, the N pieces of PUSCH resource are in one-to-one correspondence with the N pieces of reporting configuration, and periodically transmits M pieces of CSI on the second PUSCH resource according to M pieces of reporting configuration, and the M pieces of CSI are in one-to-one correspondence with the M pieces of reporting configuration.

Or, after receiving the third information, the terminal may activate M sub-configurations of the first CSI reporting configuration at the same time when N sub-configurations of the first CSI reporting configuration are activated.

The first CSI reporting configuration information comprises L reporting configurations, N reporting configurations are contained in the L reporting configurations, M is less than or equal to L, N is less than or equal to L, and L is a positive integer.

In one possible design, the N reporting configurations are different from the M reporting configurations. In an exemplary embodiment, when the network device sends the third information and the fourth information, the N reporting configurations and the M reporting configurations may not overlap, where the N reporting configurations and the M reporting configurations are configured to be completely different reporting configurations, and the terminal does not expect the N reporting configurations to overlap with the M reporting configurations.

In one possible design, the same reporting configuration may exist for N reporting configurations as for M reporting configurations. For the overlapped reporting configuration, the terminal may perform CSI reporting only according to the periods corresponding to the N reporting configurations, or perform CSI reporting only according to the periods corresponding to the M reporting configurations, or perform CSI reporting according to both the periods corresponding to the N reporting configurations and the periods corresponding to the M reporting configurations.

The third information and the fourth information are illustratively downlink control information.

The third information comprises an identifier of first CSI reporting configuration information and an index of a first reporting configuration group, the first reporting configuration group comprises N reporting configurations, the fourth information comprises an identifier of the first CSI reporting configuration information and an index of a second reporting configuration group, the second reporting configuration group comprises M reporting configurations, the L reporting configurations are reporting configurations comprised by S reporting configuration groups, the S reporting configuration groups comprise a first reporting configuration group and a second reporting configuration group, each reporting configuration group in the S reporting configuration groups comprises at least one reporting configuration, and S is an integer greater than 1. The related content of the reporting configuration group may refer to the related content, and will not be described herein.

The terminal indicates that the first reporting configuration group in the first CSI reporting configuration information is activated or deactivated according to the dedicated field in the DCI. And the terminal indicates that the second reporting configuration group in the first CSI reporting configuration information is activated or deactivated according to the special domain in the DCI.

The third information and the fourth information need to be sent separately, and the active reporting configuration and the inactive portion reporting configuration need to be sent separately.
