detailed description

With the continuous evolution of communication protocols, new functions need to be introduced into the communication system, such as supporting functions such as positioning. When introducing new functions, the base station usually needs to use some physical resources of some UEs.

However, the existing UE cannot distinguish the physical resources used by the base station for the introduction of new functions, which not only limits the introduction of new functions, but also sometimes causes great interference to UE decoding and reduces the communication quality of UE.

In view of the above problems, embodiments of the present invention provide a method for configuring physical resources. By setting reserved resources, the UE uses the configured Among the uplink physical resources except the reserved resources, other resources are used to transmit uplink data, and the reserved resources are kept unused, so that the reserved resources can be used to introduce new functions into the communication system and improve the forward compatibility of the UE.

In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to FIG. 1, an embodiment of the present invention provides a method for configuring physical resources, and the method may include the following steps:

Step 11, when receiving the uplink physical resource configuration information, acquire the uplink physical resource configured by the base station based on the uplink physical resource configuration information.

In a specific implementation, the base station usually configures corresponding uplink physical resources for the UE before the UE is about to transmit uplink data.

Step 12, when the obtained uplink physical resources overlap with the reserved resources, select other resources in the obtained uplink physical resources except the reserved resources to transmit uplink data.

In a specific implementation, the reserved resource configuration information may include: location information of the reserved resource. For example, identification information of a physical resource block or resource element (Resource Element, RE) in the subframe or time slot occupied by the reserved resource.

In a specific implementation, the subframes or time slots occupied by the reserved resources may be uplink subframes or uplink time slots, may also be downlink subframes or downlink time slots, or may include both uplink subframes or uplink time slots , including downlink subframes or downlink time slots.

In a specific implementation, the reserved resources may be acquired in various ways. In an embodiment of the present invention, the reserved resource may be acquired based on pre-acquired reserved resource configuration information.

In a specific implementation, the reserved resource configuration information may be obtained from a system message sent by the base station. For example, in an LTE system, the reserved resource configuration information may be obtained from system messages such as MIB (Master Information Block), SIB (System Information Block) 1 or SIB2 sent by the base station. In the 5G system, the reserved resource configuration information can be obtained from system messages such as Minimum SI (Minimum System Information Blocks) sent by the base station. The base station may indicate which physical resource blocks or resource elements in which subframes or time slots are reserved resources through the reserved resource configuration information.

In a specific implementation, the reserved resource configuration information may also be obtained from public control signaling sent by the base station. For example, when the subframe occupied by the reserved resources is an uplink subframe or time slot, the base station may use a radio network temporary identifier (Radio Network Temporary Identifier, RNTI) known to all UEs or a group of UEs to scramble the The downlink control signaling sends the reserved resource configuration information. When the subframe occupied by the reserved resource is a downlink subframe or a time slot, the base station may send the reserved resource configuration information through an RNTI-scrambled downlink control signaling known to all UEs or a group of UEs. The base station may indicate which physical resource blocks (or physical resource block pairs) are the reserved resources through the reserved resource configuration information, or indicate which REs are the reserved resources, or indicate which physical resource blocks (or physical resource blocks) Which symbols or subcarriers in the block pair) are the reserved resources.

In a specific implementation, the reserved resources are indicated in each subframe or time slot through common control signaling, which can make the indication of reserved resources more dynamic. Moreover, the reserved resources indicated by the common control signaling may only be applicable to the current subframe or time slot, or may be applicable to multiple subframes or time slots, until the base station modifies the reserved resources through new common control signaling.

In a specific implementation, the reserved resource configuration information may also be obtained from dedicated signaling sent by the base station for indicating the reserved resource configuration information. At this point, the UE is usually in a connected state. For example, the base station may send the reserved resource configuration information through radio resource control (Radio Resource Control, RRC). The reserved resources may be indicated in units of physical resource blocks (or pairs of physical resource blocks) or in units of resource elements.

In a specific implementation, the reserved resource configuration information may further include: configuration period information of the reserved resource. The configuration period of the reserved resources may be a preset number of subframes or a preset number of time slots. According to the configuration cycle information of the reserved resources, the UE may know the interval between adjacent reserved resources. For example, if the position of the reserved resource is the first to second physical resource block in the subframe, and the configuration period of the reserved resource is 3 subframes as an example, starting from subframe 0, every 3 subframes A frame is a subframe where the reserved resources are located, and the first to second physical resource blocks in the subframe where the reserved resources are located are the reserved resources.

In a specific implementation, the obtained uplink physical resources may partially overlap, completely overlap, or not overlap with the reserved resources. When the obtained uplink physical resources partially or completely overlap with the reserved resources, the UE needs to remove the reserved resources from the obtained uplink physical resources, and only use the remaining resources to transmit uplink data. For example, the uplink physical resource configured by the base station for the UE includes 3 physical resource blocks (or physical resource block pairs), and one of the physical resource blocks (or physical resource block pairs) or one of the physical resource blocks (or physical resource block pairs) If some resource elements belong to reserved resources, the UE only uses the part of the 3 physical resource blocks (or physical resource block pairs) except the part that overlaps with the reserved resources to transmit uplink data.

In a specific implementation, once the UE of the current version receives the configuration of the reserved resources, it does not use the reserved resources. For example, the UE may not measure the cell reference signal contained in the reserved resources during the process of performing cell measurement. However, for a UE after a new function is introduced or a protocol version is updated, the base station can schedule the UE to use the reserved resources through dedicated signaling, thereby improving the forward compatibility of the UE.

In another embodiment of the present invention, referring to FIG. 2, the method may include the following steps:

Step 21, when receiving uplink physical resource configuration information, acquire uplink physical resources configured by the base station based on the uplink physical resource configuration information.

Step 22, when the obtained uplink physical resources overlap with the reserved resources, select other resources in the obtained uplink physical resources except the reserved resources to transmit uplink data.

Regarding step 21 and step 22, specific implementations may refer to the above descriptions about steps 11 and 12 respectively.

Step 23: When the downlink physical resource configuration information is received, the downlink physical resource configured by the base station is acquired based on the downlink physical resource configuration information.

In a specific implementation, before transmitting downlink data to the UE, the base station usually configures corresponding downlink physical resources for the UE.

Step 24, when the obtained downlink physical resource overlaps with the reserved resource, choose to receive downlink data on other resources except the reserved resource in the obtained downlink physical resource.

In a specific implementation, the reserved resource configuration information may include: location information of the reserved resource.

In a specific implementation, the location information of the reserved resource may include: identification information of a physical resource block or a resource element in a subframe or a time slot occupied by the reserved resource.

In a specific implementation, the subframes or time slots occupied by the reserved resources may be uplink subframes or uplink time slots, may also be downlink subframes or downlink time slots, or may include both uplink subframes or uplink time slots , including downlink subframes or downlink time slots.

In a specific implementation, the reserved resource may be acquired based on pre-acquired reserved resource configuration information. Wherein, the reserved resource configuration information may be obtained from a system message sent by the base station, may also be obtained from a common control signaling sent by the base station, or may be sent from the base station to indicate the reserved It is obtained from dedicated signaling of resource configuration information, and there is no specific limitation.

In a specific implementation, the reserved resource configuration information may further include: configuration period information of the reserved resource.

In a specific implementation, no matter whether the reserved resource configuration information includes the configuration cycle information of the reserved resources, the reserved resource configuration information may also include: the downlink physical resources except the reserved resources The proportion value used to transmit downlink data on other physical resources. The value of this ratio is between 0 and 100%. When 100% is taken, it means that the reserved resources do not affect data transmission; the closer to 0, it means that the reserved resources have a greater impact on data transmission, and the base station can transmit less data. The reference value of the data transmission size is the size of the data block transmitted by the base station to itself determined by the UE according to the downlink control signaling.

Usually, before sending data to the UE, the base station can indicate the bit size of the transport block for this transmission in the downlink control signaling. For example, the base station can indicate that the transport block size for this transmission is 500 bits, occupying 3 physical resource block pairs . The UE can learn the occupied physical resource block pair and the bit size of the transport block for this transmission according to the information in the downlink control signaling.

When the reserved resource occupies a relatively small proportion in the corresponding physical resource block (or physical resource block pair), that is, the base station can use most of the physical resources in the physical resource block (or physical resource block pair) During data transmission, due to the redundancy of data encoding and the UE’s own error correction capability, the base station uses resource elements other than reserved resources in the physical resource block (or physical resource block pair) to transmit data to the UE. , the UE can completely parse the downlink data. At this time, the reserved resource configuration information may not include the proportion value (that is, 100 %).

When the reserved resource occupies a relatively large proportion in the corresponding physical resource block (or physical resource block pair), if the base station is still a data block that can be effectively transmitted according to the complete physical resource block (or physical resource block pair) The UE cannot completely analyze the downlink data, so the base station can indicate the proportion of downlink data in other physical resources except the reserved resources through the reserved resource configuration information. For example, the base station sends a physical downlink control signaling to a certain UE, informing the UE that data will be sent to the UE on 4 physical resource blocks (or physical resource block pairs), but the 4 physical resource blocks (or physical resource block pairs) are reserved The proportion of reserved resources is very large. At this time, the base station needs to indicate the proportion of other physical resources used to transmit downlink data except the reserved resources, such as 60%. Originally, the base station can pass 4 complete physical resource blocks (or a physical resource block pair) transmits 1000-bit data to the UE. At this time, the UE needs to determine that the size of the data block actually transmitted by the base station is 1000*60%=600 bits.

In a specific implementation, the obtained downlink physical resources may partially overlap, completely overlap, or not overlap with the reserved resources. When the obtained downlink physical resources partially overlap or completely overlap with the reserved resources, the UE can receive data from the obtained downlink physical resources except the reserved resources, and not receive data on the resources overlapping with the reserved resources, In order to avoid interference to the data decoding of the UE and ensure the communication quality of the UE. For example, the downlink physical resource configured by the base station for the UE includes 3 physical resource blocks (or physical resource block pairs), and one of the physical resource blocks (or physical resource block pairs) or one of the physical resource blocks (or physical resource block pairs) If some resource elements belong to the reserved resources, the UE can only receive downlink data on the resources (that is, REs) that do not overlap with the reserved resources among the three physical resource block pairs.

It should be noted that, in a specific implementation, there is no sequence restriction between steps 21 and 22 and steps 23 and 24, specifically, it may be determined whether to perform step 21 or to perform step 23 according to the received physical resource configuration information. For example, when the physical resource configuration information sent by the base station is uplink physical resource configuration information, steps 21 and 22 may be performed in sequence. When the physical resource configuration information sent by the base station is downlink physical resource configuration information, steps 23 and 24 may be performed in sequence.

Fig. 3 is a flowchart of another method for configuring physical resources provided by an embodiment of the present invention. Referring to Figure 3, the method may include the following steps:

Step 31: When receiving downlink physical resource configuration information, acquire downlink physical resources configured by the base station based on the downlink physical resource configuration information.

Step 32, when the obtained downlink physical resource overlaps with the reserved resource, choose to receive downlink data on other resources except the downlink reserved resource among the obtained downlink physical resources.

With regard to steps 31 and 32, specific implementation may refer to the above descriptions of steps 23 and 24 respectively, and details will not be repeated here.

FIG. 4 is a flow chart of yet another method for configuring physical resources provided by an embodiment of the present invention. Referring to Figure 4, the method may include the following steps:

Step 41: When receiving downlink physical resource configuration information, acquire downlink physical resources configured by the base station based on the downlink physical resource configuration information.

In a specific implementation, before transmitting downlink data to the UE, the base station usually configures corresponding downlink physical resources for the UE.

Step 42, when the obtained downlink physical resource overlaps with the reserved resource, choose to receive downlink data on other resources except the downlink reserved resource among the obtained downlink physical resources.

In a specific implementation, the reserved resource configuration information may include: location information of the reserved resource.

In a specific implementation, the location information of the reserved resource may include: identification information of a physical resource block (or a pair of physical resource blocks) or a resource element in a subframe or a time slot occupied by the reserved resource.

In a specific implementation, the subframes or time slots occupied by the reserved resources may be uplink subframes or uplink time slots, may also be downlink subframes or downlink time slots, or may include both uplink subframes or uplink time slots , including downlink subframes or downlink time slots.

In a specific implementation, the reserved resource may be acquired based on pre-acquired reserved resource configuration information. Wherein, the reserved resource configuration information may be obtained from a system message sent by the base station, may also be obtained from a common control signaling sent by the base station, or may be sent from the base station to indicate the reserved It is obtained from dedicated signaling of resource configuration information, and there is no specific limitation.

In a specific implementation, the reserved resource configuration information may further include: configuration period information of the reserved resource.

In a specific implementation, no matter whether the reserved resource configuration information includes the configuration cycle information of the reserved resource, the reserved resource configuration information may also include: whether the base station applies the physical resource occupied by the reserved resource Instructions for transmitting downlink data. When the base station uses the physical resources occupied by the reserved resources to transmit downlink data, the reserved resource configuration information may further include: other physical resources used in the downlink physical resources except the reserved resources The proportion value for transmitting downlink data.

Regarding steps 41 and 42, specific implementations may refer to the above descriptions about steps 23 and 24, and details are not repeated here.

Step 43: When the uplink physical resource configuration information is received, the uplink physical resource configured by the base station is acquired based on the uplink physical resource configuration information.

In a specific implementation, the base station usually configures corresponding uplink physical resources for the UE before the UE is about to transmit uplink data.

Step 44, when the obtained uplink physical resources overlap with the reserved resources, select resources other than the reserved resources among the obtained uplink physical resources to transmit uplink data.

In a specific implementation, the reserved resource configuration information may include: location information of the reserved resource.

In a specific implementation, the subframes or time slots occupied by the reserved resources may be uplink subframes or uplink time slots, may also be downlink subframes or downlink time slots, or may include both uplink subframes or uplink time slots , including downlink subframes or downlink time slots.

In a specific implementation, the reserved resources may be acquired in various ways. In an embodiment of the present invention, the reserved resource may be acquired based on pre-acquired reserved resource configuration information.

In a specific implementation, the reserved resource may be acquired based on pre-acquired reserved resource configuration information. Wherein, the reserved resource configuration information may be obtained from a system message sent by the base station, may also be obtained from a common control signaling sent by the base station, or may be sent from the base station to indicate the reserved The resource configuration information is obtained in dedicated signaling (such as RRC signaling or downlink control signaling), and is not specifically limited.

In a specific implementation, the reserved resource configuration information may further include: configuration period information of the reserved resource.

Regarding steps 43 and 44, specific implementation may refer to the above descriptions about steps 11 and 12 respectively, and details are not repeated here.

In a specific implementation, when the UE transmits downlink data according to steps 41 and 42, or when the UE transmits uplink data according to steps 43 and 44, or when the UE transmits downlink data according to steps 41 and 42 and transmits uplink data according to steps 43 and 44 , the method may also include the following steps:

When receiving the reserved resource scheduling information, select the physical resource scheduled by the reserved resource scheduling information to perform data transmission with the base station. At this time, the reserved resource scheduling information refers to the UE For data transmission, for some UEs, data transmission may be performed only through reserved resources, and for other UEs, data transmission may be performed through reserved resources and other unreserved resources together.

Through the reserved resource scheduling information, the base station can schedule the UE to perform data transmission through the reserved resources, thereby facilitating the introduction of new functions.

In a specific implementation, the base station may send the reserved resource scheduling information in various ways, which are not specifically limited. For example, the base station may send the reserved resource scheduling information through dedicated signaling. In addition, the UE may perform uplink data transmission based on the reserved resource scheduling information, and may also perform downlink data transmission based on the reserved resource scheduling information. For example, when receiving the reserved resource scheduling information, the UE may, based on the reserved The resource scheduling information transmits uplink data on some or all physical resources of reserved resources, or receives downlink data on some or all physical resources of reserved resources.

In a specific implementation, when the UE can perform data transmission with the base station based on the reserved resource scheduling information, the reserved resource configuration information may also include: whether to use the physical resources occupied by the reserved resources to transmit downlink An indication of the data. The base station may use one or more bits to indicate in the reserved resource configuration information whether to use the physical resources occupied by the reserved resources to transmit data. Wherein, the subject that uses the physical resources occupied by the reserved resources to transmit data may be the base station, or may be the UE itself. For example, when transmitting downlink data, the base station may use the reserved resource configuration information to indicate whether the base station uses the physical resources occupied by the reserved resources to transmit downlink data. When transmitting uplink data, the base station may indicate whether the UE uses the physical resources occupied by the reserved resources to transmit downlink data through the reserved resource configuration information.

When the base station instructs the UE to use the physical resources occupied by the reserved resources to transmit data, the reserved resource configuration information may simultaneously indicate the proportion of the physical resources occupied by the reserved resources for transmitting downlink data. For example, the base station transmits data to the UE through reserved resources in three physical resource blocks (or physical resource block pairs), and the base station indicates that the physical resources (or physical resource block pairs) occupied by the reserved resources are used to transmit downlink The scale value of the data. At this time, the benchmark value of data transmission is the size of the data that the base station can transmit to the UE using the complete 3 physical resource blocks (or physical resource block pairs). For example, the base station can use the complete 3 physical resource blocks (or physical resource block pairs) 700 bits are transmitted to the UE, and the ratio value indicated by the base station is 30%, then the size of the data block transmitted by the base station to the UE by reserving resources is 700*30%=210 bits. The UE parses the data according to the fact that the transmission block of this transmission is 210 bits.

It can be seen from the above that, in the method for configuring physical resources in the embodiment of the present invention, when the obtained uplink physical resources overlap with the reserved resources, select resources other than the reserved resources among the obtained uplink physical resources to transmit uplink data , when the acquired downlink physical resources coincide with the reserved resources, select to receive downlink data on resources other than the reserved resources among the acquired downlink physical resources, so that the UE can know the unusable resources , it is convenient for the base station to perform scheduling on the reserved resources, so as to introduce new functions and improve the forward compatibility of the UE.
