The number of access devices and UEs included in the communication system shown in fig. 1 and 2 is only an example, and the embodiment of the present invention is not limited thereto. For example, more UEs may be included in communication with access device 110, access device 210, and access device 212, or more access devices may be included. In addition, in the communication system as shown in fig. 1 and fig. 2, besides the UE and the network device, it may be not limited thereto, such as a core network device or a device for carrying a virtualized network function, etc., which is obvious to those skilled in the art and will not be described in detail herein. The flow of signals or data transmission shown in fig. 1 and 2 is also merely an example and is not limited thereto.

In this embodiment of the present invention, access devices, such as the access device 110, the access device 210, and the access device 212 shown in fig. 1 and fig. 2, may be devices on an access network side for supporting a UE to access a wireless communication system, and for example, may be a Transmission Reception Point (TRP), a gtnb (generation Node B, gNB for short), a base station (base station, BS), a relay Node (relay Node), an Access Point (AP), and the like. The base station may be a macro base station, a micro base station, a home base station, or the like. The access device may be fixed or mobile.

In the embodiment of the present invention, UEs, such as UE120, UE122, UE220 and UE222 shown in fig. 1 and fig. 2, may also be referred to as a terminal (terminal), a mobile station (mobile station), a subscriber unit (subscriber unit), a station (station), a Terminal Equipment (TE), and the like. The UE may be a cellular phone (cellular phone), a Personal Digital Assistant (PDA), a wireless modem (modem), a handheld device (hand-held), a laptop computer (laptop computer), a cordless phone (cordless phone), a Wireless Local Loop (WLL) station, a tablet (pad), or the like. With the development of wireless communication technology, all devices that can access a wireless communication network, can communicate with a wireless network side, or communicate with other objects through the wireless network may be UEs in the embodiments of the present invention, such as terminals and automobiles in intelligent transportation, home devices in smart homes, power meter reading instruments in smart grid, voltage monitoring instruments, environment monitoring instruments, video monitoring instruments in smart security networks, cash registers, and the like. In the embodiment of the present invention, the UE may communicate with the access device. Communication may also be performed between multiple UEs. The UE may be stationary or mobile.

The control node in the embodiment of the present invention may be connected to an access device. The control node may perform unified scheduling on resources in the system, may configure resources for the UE, perform resource scheduling, or perform interference coordination, etc. For example, if the base station is a Node B in a UMTS system, the control Node may be a network controller, and if the base station is a small station, the control Node may be a macro base station covering the small station. Alternatively, the control node may also be a wireless network cross-system cooperative controller, and the like, which is not limited in the embodiment of the present invention.

In the embodiment of the present invention, in order to reduce interference between the UE and the UE, interference coordination may be implemented through UE-to-UE interference measurement. In the interference measurement from the UE to the UE, the resource used by the interference detection between the UE and the UE is configured, so that the utilization efficiency of the resource can be improved, and more interference coordination between the UE and the UE can be realized.

In the embodiment of the invention, in the interference measurement from the UE to the UE, the UE which may cause interference to other UEs transmits a measurement signal, and the UE which may be interfered can detect the measurement signal. A UE transmitting a measurement signal may be referred to as a transmitting UE or a measurement signal transmitting UE, which may also be referred to as an interfering UE; the UE detecting the measurement signal may be referred to as a detecting UE, or referred to as a measurement signal detecting UE, a measuring UE, and the UE may also be referred to as an interfered UE. It should be noted that one UE may cause interference to other UEs, and is an interfering UE, and may also be interfered by other UEs, and is an interfered UE. I.e. a possibly interfered UE in one scenario may also cause interference to other UEs, a transmission measurement signal may also be made. For example, in fig. 1 and 2, the UE120 and UE220 may be interfering UEs, which are transmitting UEs in UE-to-UE interference measurement, the UE122 and UE222 are interfered UEs, which are detecting UEs in UE-to-UE interference measurement. This is merely an example, and conversely, the UE120 and UE220 may be interfered UEs, and the UE122 and UE222 may be interfering UEs. The embodiments of the present invention are not particularly limited. The measurement signal is used for transmitting interference between the UE and the UE, and the measurement signal may be a Reference Signal (RS), for example, a Sounding Reference Signal (SRS), a channel state information-reference signal (CSI-RS), or a demodulation reference signal (DMRS).

The transmitting UE transmits the measurement signal on a transmitting resource for transmitting the measurement signal, and the detecting UE detects the measurement signal on a detecting resource for detecting the measurement signal. The transmission resources and detection resources may also be collectively referred to as measurement resources. Both the transmission resources and the detection resources may be configured on the network side, e.g. by the access device, or by the control node. Optionally, the reporting resource for detecting that the UE reports the measurement result may also be configured by the access device or the control node.

In the communication system 10 shown in fig. 1, in the interference measurement from the UE120 to the UE122, the UE120 needs to transmit a measurement signal, and the UE122 may detect the measurement signal transmitted by the UE 120. The access device 110 may configure the transmission resource for the UE120 to transmit the measurement signal and the detection resource for the UE122 to detect the measurement signal, and optionally, the access device 110 may further configure a reporting resource for the UE122 to report the measurement result. Then, the access device 110 sends the configured resource information to the UE120 and the UE122, respectively. Or, the control node 130 may configure a resource for the UE120 to transmit the measurement signal and a resource for the UE122 to receive the measurement signal, or optionally, may also configure a reporting resource for the UE120 to report the measurement result, and the access device 110 obtains the configured resource information and then sends the resource information to the UE120 and the UE122, respectively.

In the communication system as shown in fig. 2, in the interference measurement from the UE220 in the cell 2C1 to the UE222 in the cell 2C2, the UE220 needs to transmit a measurement signal, and the UE222 can detect the measurement signal transmitted by the UE 220. The access device 210 may configure the transmission resource for the UE220 to transmit the measurement signal, and then transmit the configured transmission resource to the UE 220; the access device 212 may configure a detection resource for detecting the measurement signal by the UE222, and the access device 212 may also configure a reporting resource for reporting the measurement result by the UE222, and then send the configured resource to the UE 222. When performing resource allocation, the access device 210 and the access device 212 may send the condition of their resource allocation to each other. Alternatively, the resources used by the UE220 and the UE222 may both be configured by the access device 210, and then the access device 210 sends the transmission resource to be used by the UE220 to the UE220, sends the detection resource to be used by the UE222 to the access device 212, and then the access device 212 sends the detection resource to the UE 222. Alternatively, the control node 230 may configure the resources to be used by the UE220 and the UE222, and then the

access devices

210 and 212 transmit the configured resources to the UE220 and the UE222, respectively.

In this embodiment, there may be an association relationship between the transmission resource configured for the transmitting UE and the detection resource configured for the detecting UE, and in the time domain, the transmission resource may at least include the detection resource. The number of resource symbols of the transmission resource may be greater than or equal to the number of resource symbols of the detection resource, and the time domain length of the resource symbols of the transmission resource is equal to the time domain length of the resource symbols of the detection resource. For example, as shown in fig. 3(a), in the time domain, the detection resource is one resource symbol P0, the transmission resource may be two consecutive resource symbols, and the two consecutive resource symbols at least include the resource symbol P0, and the resource symbol P0 may span the two consecutive resource symbols of the transmission resource. Alternatively, the time domain length of the resource symbol of the transmission resource is greater than the time length of the resource symbol of the detection resource, as shown in fig. 3 (b), and the resource symbol of the transmission resource at least includes the resource symbol P1 of the detection resource. This relationship between the transmission resources and the detection resources may enable more accurate UE-to-UE interference measurements.

In an embodiment of the present invention, the transmission resources and the detection resources may include at least one of time domain resources and frequency domain resources. After configuring at least one specific transmission resource for the transmitting UE, the corresponding detection resource is also configured for the detecting UE.

In the embodiment of the present invention, the access device may configure information in the UE-to-UE interference measurement to the UE in the interference measurement through configuration information of cell specific (cell specific) and configuration information of UE specific (UE specific). For example, the UE is notified of the required resource information. The method can comprise notifying the configured transmission resources to the transmission UE, notifying the detection UE of the detection resources, and also notifying the reporting resources to the detection UE. The access device may transmit the cell-specific configuration information through Radio Resource Control (RRC) signaling or System Information Block (SIB) signaling. The access device may send the UE-specific configuration information through a Media Access Control (MAC) signaling, or a Downlink Control Information (DCI) signaling or an RRC signaling. This configuration may also be referred to as a two-layer signaling configuration in this embodiment. The cell-specific configuration information is sent to all or some UEs in the cell, and all or some UEs in the cell can obtain the same cell-specific configuration information. The UE-specific configuration information may be sent in the form of a UE group, that is, one configuration information includes configuration information of a plurality of UEs, and the configuration information is combined into one configuration information in the form of a domain.

The cell-specific configuration information may include available resource information, and the available resources may not be actually used resources. The UE-specific configuration information may include information indicating resources actually required to be used by the UE, which are included in the resources that may be used by the UE. The UE-specific configuration information is sent to a specific UE, which is not received by other UEs. After receiving the cell-specific configuration information and the UE-specific configuration information, the UE may obtain the transmission resource, or the detection resource, or the report resource configured to itself, by combining the resource configuration information included in the two kinds of information.

The cell-specific configuration information may include time domain resource configuration information, and the time domain resource may be a time domain resource of a transmission resource, a time domain resource of a detection resource, or a time domain resource of a reporting resource. The time domain resource configuration information may include information of a measurement resource group, where the measurement resource group includes at least one resource cycle, and the measurement resource group information may include the number of resource cycles included in the measurement resource group, or include the number of time domain units included in the resource cycle, where the time domain units may be frames, subframes, symbols, or slots. The resource period represents a repetitive characteristic of the measurement resource in a time domain, and the resource period may include a plurality of frames, subframes, symbols, or slots, and each resource period may include at least one resource, such as a frame, a subframe, a symbol, or a slot, that can be used for measuring a signal. The resource period may also be referred to as a measurement resource period, or measurement period. The measurement resource group may also be referred to as a resource cycle set, or a measurement resource set, etc. The UE may use the configured resources within the set of measurement resources. The time domain resource configuration information may further include resource period information and available resource indication information in the resource period. The resource cycle information may be, for example, a duration of a resource cycle, or a number of time domain units included in the resource cycle. The available resource indication information is used to indicate the available resource location in the resource cycle, such as the number of resources, offset information, and the like.

The UE-specific configuration information may include time domain resource configuration information sent to a specific UE or UEs in a specific UE group, where the time domain resource may be a time domain resource of a transmission resource, a time domain resource of a detection resource, or a time domain resource of a reporting resource. The time domain resource allocation information may be resource information that needs to be used by the UE, and transmission resource information in the resource period, which is used for the UE to transmit the measurement signal, is also resource information that is actually allocated to the UE, such as time domain unit index information, for example, a frame number, a subframe number, a symbol index number, or a slot number. The time domain resource configuration information may further include location information of the measurement resource group, for example, start location information of the measurement resource group. If the time domain resource configuration information of the specific UE includes time domain resource information of a transmission resource that the UE needs to use, the UE-specific configuration information may further include indication information for triggering transmission of a measurement signal by the UE, and at this time, the time domain resource information of the transmission resource may be included in UE-specific configuration information carried in, for example, RRC signaling, and the indication information for triggering transmission of the measurement signal by the UE may be included in UE-specific configuration information carried in, for example, DCI signaling.

The resources configured for the UE through the cell-specific configuration information and the UE-specific configuration information are allocated to the same UE in the measurement resource group for use, that is, the UE uses the configured resources in at least one measurement period included in the measurement resource group. The UE performs aperiodic usage of the configured resource, i.e., the configured resource is used within the range of the measurement resource group.

Fig. 4 is a schematic time domain resource diagram of a transmission resource. In fig. 4, each subframe is 10ms, and one resource period is 20ms, i.e. includes 2 subframes. One measurement resource group includes 8 resource periods, i.e., includes 16 subframes. For example, measurement resource group 1 includes subframes 0-15, and measurement resource group 2 includes subframes 16-31. The last symbol of each subframe may be used to transmit a measurement signal. The cell-specific configuration information may include measurement resource group information, for example, the measurement resource group includes the number 8 of resource periods, which is 20ms or includes the number 2 of subframes, and the information of available transmission resources in the resource periods is symbol X and symbol Y. The UE-specific configuration information may include, for example, the transmission resource needed by the UE120 is symbol Y, and the starting position of the measurement resource group is subframe 0. The transmission resource configured to the UE120 is symbol Y in

subframes

1, 3, 5, 7, 9, 11, 13, 15, and 17 in measurement resource group 1. Although there are symbols Y in other resource periods of measurement resource group 2 and other measurement resources in the diagram of fig. 4, the UE120 only performs aperiodic transmission of measurement signals, i.e., transmits measurement signals in symbols Y of measurement resource group 1. Without periodic transmission of measurement signals in symbols Y in the other sets of measurement resources 2-N. N is a natural number of 2 or more, and X and Y are only labels for distinguishing two symbols and may not have a specific meaning. Of course, in the same measurement resource group, different resources in one measurement period may be configured for different UEs to use, for example, symbol X in measurement resource group 1 may be allocated to a transmitting UE different from UE120 to use. The symbols Y in measurement resource group 2 may be configured to transmit measurement signals to other UEs in the same manner as described above. Similarly, the detection resource and the reporting resource can also be allocated in the manner shown in fig. 4. It should be noted that the resource structure shown in fig. 4 is only an example, the subframe and the symbol may be other types of resource units, and the duration of the resource period and the number of resource periods included in the measurement resource group are not limited thereto, and may be adjusted according to the actual system and needs.

In the embodiment of the present invention, the cell-specific configuration information and the UE-specific configuration information that are sent to the UE by the access device may further include frequency domain resource configuration information. The frequency domain resources may be divided into different frequency domain resource units, such as sub-bands, Component Carriers (CCs), Resource Blocks (RBs), Resource Block Groups (RBGs), consecutive RBs or non-consecutive RBs. The frequency domain resource allocation information in the cell-specific allocation information may include frequency domain resource unit information, such as location information of the sub-band, the component carrier, the RB, the RBG, consecutive RBs, or non-consecutive RBs. The frequency domain resource unit information is also referred to as frequency domain location information. The frequency domain resource information in the UE-specific configuration information may include RS comb information to be used for transmitting resources, detecting resources, or reporting resources at the frequency domain position indicated by the frequency domain position information. The frequency domain resource unit information can be sent to the UE through RRC signaling, and the RS comb information can be sent to the UE through DCI signaling or MAC signaling. The number of DCI indication bits is required to be related to the number of RS comb fingers. For example, if the number of RS comb is 4, the number of bits used for DCI is 2. Optionally, the RS comb information may also be sent to the UE through RRC signaling or broadcast signaling, and the frequency domain location information is sent to the UE through DCI signaling or MAC signaling. Or, the RS comb information and the frequency domain position information may be sent to the UE through RRC signaling, or the SRS comb information and the frequency domain position information may be sent to the UE through DCI signaling or MAC signaling.

For example, as shown in fig. 5, blocks 0, 1, 2, and 3 in the frequency domain are exemplary frequency domain resource units, which may be sub-bands, component carriers, RBs, RBGs, consecutive RBs, or discontinuous RBs, and each frequency domain resource unit may have a plurality of RS combs, such as comb a to comb f. And the specific frequency domain resource can be determined through the frequency domain resource unit information and the RS comb information.

By the resource allocation method, the measurement resources can be reused by a plurality of UEs in the interference measurement from the UEs to the UEs, and especially when a large number of UEs exist in a cell, the utilization efficiency of the measurement resources can be improved, and the efficiency of the interference measurement can be improved. The throughput rate of the system is improved, the interference among the UE is reduced, and the performance of the UE is improved.

In the embodiment of the present invention, in addition to configuring resources required to be used for the UE-to-UE interference measurement, at least one of timing of interference measurement, power of a measurement signal, and a measurement trigger mechanism in the UE-to-UE interference measurement may be configured. The timing of the interference measurement in the UE-to-UE interference measurement, the power of the measurement signal, or the measurement trigger mechanism may be configured by at least one of the cell-specific configuration information and the UE-specific configuration information. In the UE-to-UE interference measurement, at least one of the timing of measurement, the power of the measurement signal, and the measurement trigger mechanism may be configured separately without being configured with the measurement resource, or may be configured with the measurement resource. The timing of the measurements, the power of the measurement signal or the measurement trigger mechanism may also be configured by the access device or the control node.

In the UE-to-UE interference measurement, the configuration of the measurement timing may be that the access device may send N to the UE_TASaid N is_TAIs a Time Advance (TA) value. UE according to the N_TATiming adjustment of emission or detection measurement signals, N_TAThe method and the device can be used for timing adjustment when the transmitting UE transmits the measurement signal, and can also be used for timing adjustment when the detecting UE receives the measurement signal. For example, the adjusted length may be (N)_TAA/2) time units, e.g. of (N)_TA/2)*T_sWherein, T_sCan satisfy 307200. T _s10 ms. The transmission timing is set to be forward (N) with respect to the received downlink frame_TA/2)*T_SThe timing for detecting the UE may be set to be forward (N) with respect to its own downlink frame_TA/2)*T_S. As shown in fig. 6, the measurement radio frame i is forward (N) with respect to the downlink radio frame_TA/2)*T_SSecond, where the radio frame is measured, i.e. the radio where the resource is measuredAnd the frame comprises a wireless frame where the emission resource is located or a wireless frame where the detection resource is located. The configuration information related to the measurement timing may be sent through cell-specific configuration information or may be sent through UE-specific configuration information. For example, the cell-specific configuration information may be notified through RRC signaling or SIB signaling, and the UE-specific configuration information may be notified through DCI signaling or MAC signaling.

In the interference measurement from the UE to the UE, the configuration of the measurement trigger mechanism may be to configure a trigger condition for measuring the measurement signal for the detection UE, and when the measurement trigger condition is satisfied, the detection UE starts to detect the measurement signal. For example, the measurement trigger condition may be that the Reference Signal Received Power (RSRP) of the serving cell is lower than a preset threshold, or the Reference Signal Received Quality (RSRQ) of the serving cell is lower than a preset threshold. By configuring the measurement trigger mechanism, the measurement operation from the UE to the UE in the UE measurement can be reduced, the energy consumption of the UE is saved, and the overhead of system reporting can be reduced.

The power configuration of the measurement signal may be the transmission power of the measurement signal configured by the network side. For example, the specific power value of the measurement signal may be transmitted to the transmitting UE through RRC signaling, MAC signaling, or DCI signaling. Alternatively, a set of predefined power values may be determined, and then power indication information may be signaled to the transmitting UE through RRC signaling, MAC signaling, or DCI signaling, the power indication information indicating one power value corresponding to the set of predefined power values. Alternatively, a power adjustment coefficient is configured to the transmitting UE, and the power adjustment coefficient may be used to adjust the transmission power of the measurement signal low, for example, so that the transmission power of the measurement signal obtained by the power adjustment coefficient is lower than the power value obtained by the following formula:

P’_c(i)＝min{P_CMAX,c(i),P_OFFSET,c(m)+10log₁₀(M_c)+P_{O_PUSCH,c}(j)+α_c(j)·PL_c+f_c(i)}

wherein, P'_c(i) Is a power value, c is a serving cellI is the subframe number, P_CMAX,CMaximum transmit power for the configured UE of subframe i on serving cell c. P_OFFSET,cFor parameters configured in a semi-static manner at a higher layer, m corresponds to different trigger modes of the measurement signal, for example, m may be 0 or 1, where m ═ 0 may indicate that the trigger mode is 0, and m ═ 1 may identify that the trigger mode is 1. M is the number of RBs occupied by the transmission bandwidth of the measurement signal. fc is the power control adjustment state of the current physical uplink shared control signal (PUSCH) in the cell c. P_{O_PUSCH}And alpha_c(j) Parameters configured for the serving cell c for higher layers. PL is the downlink path loss value from the serving cell c to the UE.

For example, the adjusted power may be: p_c(i)＝P_{adjust-offest}+P’_c(i) Wherein P is_{adjust-offest}Can be a negative number whose absolute value is less than said P'_c(i) In that respect Alternatively, the adjusted power value may be: p_c(i)＝P’_c(i)-P_{adjust-offest}Wherein P is_{adjust-offest}Can be a positive number, less than P'_c(i) In that respect Alternatively, the adjusted power value may be: p_c(i)＝P_{adjust-offest}* P’_c(i) Wherein P is_{adjust-offest}May be 0 < P_{adjust-offest}＜1。

The specific value, or a predefined set of measurement values and the power adjustment parameter, may be determined by the network side according to the actual conditions of the system. By means of power configuration, different transmitting UEs can use different transmitting powers, so that the interfered UE can be better enabled to detect the interference of the potential interfering UE. By configuring a specific power value or a predefined power value, a more accurate interference situation, such as a path loss value, can be obtained in the UE-to-UE interference measurement. Through the configuration of the power adjustment coefficient, the energy consumption of the UE can be reduced.

In the embodiment of the present invention, the transmitting UE may obtain the transmission resource according to the received cell-specific configuration information and UE-specific configuration information, and transmit the measurement signal in the measurement resource group. Alternatively, the transmission timing may be adjusted by a timing configuration, the measurement signal being transmitted with a configured measurement signal transmission power.

The detection UE may obtain the detection resource according to the cell-specific configuration information and the UE-specific resource configuration information, and detect the detection signal sent by other UEs. And can report the measurement result to the access device. Alternatively, the detecting UE may detect the measurement signal when the measurement trigger condition is satisfied according to the configured measurement trigger condition. Optionally, the access device may perform interference coordination after receiving the measurement result. The access device may also send the received measurement result to the control node, and the control node performs interference coordination.

A communication method according to an embodiment of the present invention is described below with reference to fig. 7, and may be used in UE-to-UE measurements. The contents described in the above embodiments of the present invention can be applied in combination to the communication method of the present embodiment.

In the communication method, the network side may configure the transmission resources of the transmitting UE.

In step 701, a transmitting UE receives cell-specific configuration information.

The cell-specific resource information may be sent by the access device to the transmitting UE via RRC signaling or SIB signaling. For example, in communication system 10, access device 110 may send RRC signaling or SIB signaling to UE 120. In communication system 20, the access device 210 may send RRC signaling or SIB signaling to UE 220. The RRC signaling or SIB signaling includes the cell-specific configuration information. The cell-specific configuration information may include time domain resource configuration information of transmission resources, the time domain resource configuration information of the transmission resources may include measurement resource group information of the transmission resources, and the time domain resource configuration information of the transmission resources may further include resource period information of the transmission resources, information of available transmission resources within a resource period, and the like. The cell-specific configuration information may further include frequency domain resource information of transmission resources, and the frequency domain resource information of the transmission resources may include frequency domain position information or RS comb information.

In step 702, the transmitting UE receives UE-specific configuration information.

The UE-specific resource information may be sent by the access device to the UE through MAC signaling, DCI signaling, or RRC signaling. For example, in communication system 10, access device 110 may send MAC signaling, DCI signaling, or RRC signaling to UE 120. In communication system 20, the access device 210 may send MAC signaling, DCI signaling, or RRC signaling to UE 220. The MAC signaling, DCI signaling, or RRC signaling includes UE-specific configuration information, where the UE-specific configuration information may include time domain resource configuration information of transmission resources, and the time domain resource configuration information may include information of transmission resources required to be used, and may also include location information of a measurement resource group. The time domain resource configuration information of the transmission resources contained in the UE specific resource information may further include indication information for triggering the transmitting UE to transmit the measurement signal. In this case, the indication information may be included in UE-specific configuration information carried by DCI signaling, and the information of the transmission resource to be used may be included in UE-specific configuration information carried by RRC signaling. The UE-specific configuration information may further include frequency domain resource information of transmission resources, and if the cell-specific configuration information includes frequency domain location information, the frequency domain resource information in the UE-specific configuration information includes RS comb information; and if the cell-specific configuration information includes RS comb information, the frequency domain resource information in the UE-specific configuration information includes frequency domain location information.

The access device may further send at least one of configuration information of timing and power configuration information of measurement signals to the transmitting UE. The timing configuration information and the power configuration information of the measurement signal may be transmitted by the cell-specific configuration information in step 701, or may be transmitted by the UE-specific configuration information in step 702.

The transmitting UE may obtain measurement resource group information after obtaining the cell-specific configuration information. According to the UE-specific configuration information, the transmission resource information in the resource period corresponding to the transmitting UE is obtained, so that the transmission resources in the measurement resource group can be obtained. For example, in the example shown in fig. 4, from the set of measurement resources of subframes 0 to 15, symbol Y in

subframes

1, 3, 5, 7, 9, 11, 13, 15, and 17 can be obtained as a transmission resource.

Alternatively, if the UE-specific configuration information does not include location information of the measurement resource group, the UE may determine the location of the measurement resource group by itself. After receiving the UE-specific configuration information, the UE may determine that the transmission resource is in the next measurement resource group that satisfies the measurement resource group boundary condition after receiving the UE-specific configuration information. The boundary condition of the measurement resource group may be S% T ═ 0, where S is a resource unit index number and T is the number of resource units included in the measurement resource group. The resource units may be frames, subframes, slots, symbols, etc. For example, in the example shown in fig. 4, if the transmitting UE receives the UE-specific configuration information in subframe 13, and the next subframe satisfying the subframe number% 16 ═ 0 is measurement resource group 2 starting from subframe 16, the transmitting UE obtains symbol Y in

subframes

17, 19, 21, 23, 25, 27, 29, and 31 in measurement resource group 2 as the transmission resource.

The access device may also send the DCI signaling on a specific resource unit index, for example, send the DCI signaling on a resource unit index satisfying S% T ═ 0, so that the UE may receive the DCI signaling only on the resource unit index satisfying S% T ═ 0 without monitoring the DCI signaling on all resource units, which may save energy consumption of the terminal.

In the communication method, a detection resource for detecting the UE may be configured. The method further comprises the following steps:

in step 703: it is detected that the UE receives cell-specific configuration information.

The cell-specific configuration resource information may be sent by the access device to the detecting UE through RRC signaling or SIB signaling. For example, in communication system 10, the access device 110 may send the cell-specific configured resource information to UE 122. In communication system 20, the access device 212 may send the cell-specific configuration resource information to UE 222. The cell-specific configuration information may include time domain resource configuration information of the detection resource, the time domain resource configuration information of the detection resource may include measurement resource group information of the detection resource, and the time domain resource configuration information of the detection resource may further include resource cycle information of the detection resource, information of the available detection resources within the resource cycle, and the like. The cell-specific configuration information may further include frequency domain resource information of the detection resource, and the frequency domain resource information may include frequency domain position information or RS comb information.

In step 704, the detecting UE receives UE-specific configuration information.

The UE-specific configuration information may be sent by the access device to the detecting UE through MAC signaling, DCI signaling, or RRC signaling. For example, in communication system 10, access device 110 sends the UE-specific configuration resource information to UE 122. In communication system 20, the access device 212 sends the cell-specific configuration resource information to UE 222. The UE-specific configuration information may include time domain resource configuration information of the detection resource, and the time domain resource configuration information may include information of a resource of the detection resource that needs to be used, such as resource unit index information, and may also include location information of the measurement resource group. The UE-specific configuration information may further include frequency domain resource information of the detection resource, and if the cell-specific configuration information includes frequency domain location information of the detection resource, the frequency domain resource information in the UE-specific configuration information includes RS comb information of the detection resource; and if the cell-specific configuration information includes RS comb information, the frequency domain resource information in the UE-specific configuration information includes frequency domain location information of the detection resource.

The access device may further send at least one of detection trigger configuration information and timing configuration information to the detecting UE. The detection trigger configuration information and the timing configuration information may be sent to the detecting UE through cell-specific configuration information in step 703, or may be sent to the detecting UE through UE-specific configuration information in step 704.

The detecting UE may obtain measurement resource group information of the detection resource after obtaining the cell-specific configuration information. According to the UE-specific configuration information, the detection resource information in the resource cycle of the detection resource corresponding to the detection UE is obtained, so that the detection resource in the measurement resource group can be obtained. If the UE-specific configuration information does not include location information of the measurement resource group, the UE may determine the location of the measurement resource group by itself, so as to obtain a specific measurement resource to be used.

The UE may also receive reporting resource information, where the reporting resource information may be separately included in the cell-specific configuration information, or may also be separately included in the UE-specific configuration information, or may be configured by using the cell-specific configuration information and the UE-specific configuration information in a configuration manner of, for example, detection resources.

In the embodiment of the present invention, the configurations of the transmission resource and the detection resource may be independent, so there is no defined relationship between the above steps 701 and 702 describing the transmission resource allocation and the

steps

703 and 704 describing the reception resource allocation, and the steps 701 and 702 may be performed before the

steps

703 and 704, or may be performed after the steps, or may be performed simultaneously.

In the embodiment of the present invention, optionally, step 704 may not be included, that is, the network side may not send UE-specific configuration information to the detecting UE.

In the embodiment of the present invention, optionally, the communication method may further include a UE-to-UE interference detection method. As illustrated in fig. 6, the interference detection method may include:

step 705: the transmitting UE transmits measurement signals on the transmission resources.

Optionally, the transmitting UE may transmit the measurement signal on the transmission resource configured as described above. For example, in communication system 10, UE120 may transmit measurement signals on configured transmission resources. In communication system 20, UE220 may transmit measurement signals on configured transmission resources.

Optionally, the transmitting UE may measureThe transmission timing of the resource is set to be forward (N) with respect to the received downlink frame_TA/2)*T_S。

Optionally, the transmitting UE may transmit the measurement signal using a specific measurement signal power value notified by the access device. Or, if a group of measurement signal power values is predetermined in the transmitting UE, the transmitting UE may select the transmission power corresponding to the power indication information from the predetermined measurement signal power values by using the power indication information notified by the access device, and send the measurement signal. Alternatively, the transmission signal may be adjusted according to the power adjustment coefficient P notified by the access device_{adjust-offest}The transmit power of the measurement signal is determined. The measurement signal is transmitted according to the configured transmission power, so that the accuracy of interference measurement can be improved, the energy loss caused by the transmission of the measurement signal by the UE can be effectively reduced, and the power consumption of the UE can be reduced.

Step 706, detecting that the UE detects the measurement signal on the detection resource.

Optionally, the detecting UE may detect the measurement signal sent by the transmitting UE on the detection resource configured as described above. For example, in communication system 10 UE122 detects measurement signals transmitted by UE120 on detection resources. In communication system 20, UE222 detects measurement signals transmitted by UE220 on detection resources.

Optionally, the detecting UE may determine whether to perform detection on the measurement signal according to the detection trigger mechanism configuration information, and according to the configured detection trigger condition, the detecting UE obtains information of the configured measurement signal receiving resource through the measurement trigger condition, and if the RSRP of the serving cell measured by the detecting UE is higher than the preset threshold, the detecting UE does not need to measure and report the measurement signal. And when the RSRP measured by the UE is lower than a preset threshold, the UE starts to start the interference measurement from the UE to the UE. In this way, the measurement operation of the UE can be reduced, the energy consumption of the UE can be saved, and the overhead of system reporting can be reduced.

The detecting UE may not perform timing adjustment when detecting the measurement signal on the detection resource. Taking the system shown in fig. 2 as an example, in fig. 8, the time delay for the UE220 to transmit the signal to the access device 212 isT1, the latency for access device 210 to transmit signal to UE222 is T2, and the latency for UE220 to transmit signal to UE222 is T3. The delay of the transmitting UE220 adjusts the timing offset between the transceive measurement signals forward relative to the downlink frame to be T2-T3, typically T3 is small, and T2 is the propagation delay, which is within the Cyclic Prefix (CP) range for small coverage or large subcarrier spacing scenarios. Therefore, the receiving and transmitting symbols can be aligned, and accurate measurement can be realized. Alternatively, when the UE detects the measurement signal on the detection resource, N may be the same as N_TAMaking timing adjustments, e.g. forward (N) with respect to the downlink frame_TA/2)*T_S. Thus, in the scenario shown in fig. 8, the timing offset between the transmitted signal and the detected signal is T3. T3 relates to the distance between UE220 and UE 222. Usually, the users will not be far away from each other, and if the users are far away, the interference will be small and negligible. Therefore, the positions of the measurement signals are also within the normal CP range, so that the progress of the interference measurement can be ensured.

Optionally, in this embodiment of the present invention, if step 704 is not included, the detecting UE may measure the measurement signal according to the information determined in the cell-specific configuration, that is, the detecting UE may detect all resources available for sending the measurement signal in the resources in the measurement resource group. For example, if the cell-specific configuration information configures the measurement resource set and the resource period as in the example shown in fig. 4, the detecting UE may perform detection for both symbol X and symbol Y in the resource period. If the other detecting UEs that receive the cell-specific configuration information also do not receive the UE-specific configuration information, the other detecting UEs may also detect all the resources that can be used for sending the measurement signal in the measurement resource group.

Step 707, the UE reports a detection result obtained by detecting the measurement signal to the access device.

And after the UE detects the measurement signal, reporting the detection result obtained by processing on the configured reporting resource. For example, in communication system 10, UE122 may report the detection result to access device 110. In the communication system 20, the UE222 may report the detection result to the access device 212.

Optionally, in this embodiment of the present invention, if step 704 is not included, in step 706, the detecting UE detects all resources available for sending the measurement signal in the resources in the measurement resource group, so as to obtain a plurality of detection results corresponding to the number of available resources.

In this embodiment of the present invention, the communication method may further include:

step 708: and carrying out interference coordination among the UE according to the detection result.

The access device receiving the detection result may coordinate interference between the transmitting UE and the detecting UE according to the detection result. Or, the access device may also send the detection result to a control node, and the control node performs interference coordination. For example, in communication system 10, access device 110 may coordinate interference between UE120 and UE122 according to the detection result, or access device 110 may send the detection result to control node 130, and control node 130 coordinates interference between UE120 and UE122 according to the detection result. In the communication system 20, the access device 212 may coordinate interference between the UE220 and the UE222 according to the detection result, or the access device 212 sends the detection result to the control node 230, and the control node 230 coordinates interference between the UE220 and the UE222 according to the detection result.

For example, the access device receiving the detection result may determine whether the detected UE is actually interfered according to the detection result, if the interference level is lower than a preset threshold, the detected UE may further maintain the detection state, and if the interference level of the detected UE reaches the preset threshold, the access device may determine that the transmitting UE is an interfering UE. In communication system 10 as shown in fig. 1, access device 110 may directly determine that UE120 is an interfering UE. In the communication system 20 shown in fig. 2, the access device 210 may send an interference query message to the access device 212, which includes resource location information, radio frame number, and the like. The access device 212 determines that the UE220 is an interfering UE according to the information in the interference query message, returns a query result to the access device 210, and the access device 210 determines that the UE220 and the UE222 are interference sources.

After determining the interference source, when performing data transmission, the transmitting UE may not be scheduled for data transmission in the opposite direction at the time domain resource location where the UE is detected to transmit data. For example, in communication system 10 shown in fig. 1, when scheduling UE120 to perform uplink transmission, access device 110 may schedule UE122 not to perform downlink transmission on the time domain resource for uplink transmission of UE 120. In the communication system 20 shown in fig. 2, when the access device 210 schedules the UE220 for uplink transmission, it may send a scheduling coordination request message to the access device 212, where the scheduling coordination request message includes time-frequency resource information for uplink transmission of the UE220, and the access device 212 may not schedule the UE222 for downlink transmission on the time-frequency resource. Or, when the access device 210 schedules the UE220 for data transmission, the access device 210 sends a DCI signaling, and the access device 212 demodulates the DCI signaling to obtain scheduling information of the access device 210 for the UE220, and does not schedule the UE222 for data transmission on a time-frequency resource scheduled by the scheduling information. Alternatively, the access device 210 and the access device 212 may determine the priority of resource usage, and invoke the UE220 and the UE222 that interfere with each other on different time-frequency resources according to the priority.

As shown in fig. 9, which is a schematic structural diagram of a communication device 90 according to an embodiment of the present invention, the communication device 90 may be a transmitting UE described in the above-mentioned embodiment of the present invention, such as the UE120 included in the communication system 10 or the UE220 in the communication system 20, or may also be a detecting UE described in the above-mentioned embodiment, such as the UE122 in the communication system 10 or the UE222 in the communication system 20. The device 90 may also be an access device such as the access device 110 or the access device 210 described in the above embodiments of the present invention. Alternatively, the control node described in the above embodiments of the present invention, such as the control node 130 or the control node 230, may also be used. The contents described in the above embodiments can be applied in combination to the present embodiment. The device 90 may include a memory 910 and a processor 920, the memory 910 being configured to store instructions, the processor 920 being configured to execute the instructions stored by the memory 910, and when the instructions stored by the memory are executed by the processor, the access device being configured to implement the method described above as being performed by a transmitting UE or a detecting UE or an access device or a control node.

As shown in fig. 10, another communication device 100 is shown in the embodiment of the present invention. The communication device 100 includes a transceiver 1001 and a processor 1002. The communication device 100 may be an access device described in the above embodiments of the present invention, such as the access device 110 and the access device 210, and the processor 1002 may be configured to configure the transmission resource, or detect the resource or report the resource. The transmission resource, or the detection resource or the reporting resource may be configured by the cell-specific configuration information and the UE-specific configuration information described in the above embodiments. The processor 1002 may also be configured to measure signal power, measure trigger conditions or timing, and the like. The processor 1002 may also perform interference coordination according to a detection result reported by the UE.
