Description

Communication method and device

Technical Field

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

Background

At present, when Time Division Duplex (TDD) uplink and downlink allocations (UL/DL patterns) between cells of adjacent base stations are different, data transmission of a first terminal device in one cell may interfere with data transmission of a second terminal device in another cell, and this interference may be referred to as cross-link interference (CLI).

In order to alleviate the impact of CLI, the network device may configure CLI measurement for the second terminal device, and let the second terminal device measure the configured reference signal. The reference signal measured by the second terminal device is the reference signal sent by the first terminal device to the network device, and the second terminal device obtains the measurement result of the reference signal and performs layer 3filtering (layer 3 filtering). The second terminal device may report the filtered CLI measurement result, and the network device may perform coordinated scheduling on the second terminal device based on the CLI measurement result, so as to reduce or avoid the CLI.

In a wireless communication system, in order to save power consumption of a terminal device on the premise of ensuring effective transmission of data, a Discontinuous Reception (DRX) mode is introduced. In the DRX mode, the terminal device may monitor a Physical Downlink Control Channel (PDCCH) at an active time, perform data transmission with the network device, and perform sleep at a time other than the active time.

However, since the terminal device is controlled by DRX when transmitting the reference signal, the validity of the CLI measurement may be affected.

Disclosure of Invention

The application provides a communication method and a communication device, which are used for improving the effectiveness of CLI measurement.

In a first aspect, an embodiment of the present application provides a communication method. The method may be performed by a first terminal device in an embodiment of the present application. In the method, a first terminal device may receive a resource configuration. The resource configuration may include parameters of the periodicity of the target resource. The target resource herein may be a resource for CLI measurement, or may also be a resource other than a resource for CLI measurement. When the target resource is a resource for CLI measurement, the target resource may be a periodic Sounding Reference Signal (SRS) resource or may also be a semi-persistent SRS resource. The first terminal device may transmit the target resource according to the parameter of the period at the inactive time. The inactive time here may be an inactive time of the first terminal device in Discontinuous Reception (DRX).

Based on the scheme, the first terminal device can send the target resource in the inactive time, can avoid the influence of DRX on the resource for CLI measurement, and can only send the resource in the active time of DRX, thereby causing the problem of CLI measurement failure, and improving the effectiveness of CLI measurement.

In a possible implementation manner, the first terminal device may further send the target resource according to the parameter of the cycle at the active time of DRX.

Based on the scheme, the first terminal device can also send the target resource according to the periodic parameter at the active time or the inactive time of the DRX, and the first terminal device can not control the target resource to be sent by the DRX, so that the effectiveness of CLI measurement can be improved.

In one possible implementation, the first terminal device may determine the target resource from among the one or more resources indicated by the resource configuration.

Based on this scheme, if the resource configuration indicates a plurality of resources, the first terminal device may determine a target resource for CLI measurement among the plurality of resources and transmit the target resource at an inactive time or an active time of DRX.

In a possible implementation manner, the resource configuration may further include first indication information; the first indication information may be used to indicate the target resource.

Based on the scheme, the first terminal device can determine the target resource through the first indication information carried in the resource configuration, so that information interaction with the network device can be reduced, and signaling overhead is saved.

In a possible implementation manner, the first terminal device may further receive first indication information; the first indication information may be used to indicate the target resource.

Based on the scheme, the first terminal device may determine a target resource for CLI measurement among one or more resources according to the first indication information transmitted by the network device, and transmit the target resource at an inactive time or an active time of DRX.

In one possible implementation, the resource configuration may include an identification of one or more resources; the first indication information may be used to indicate an identity of the target resource.

Based on the scheme, the one or more resources may be indicated by the identifier of the one or more resources, and the first terminal device may also determine, from the one or more resources, a target resource for CLI measurement according to the identifier of the target resource indicated by the first indication information.

In a possible implementation manner, the first indication information is further used to trigger the first terminal device to send the target resource according to the parameter of the cycle during the non-active time of DRX. In an example, the target resource may be further indicated by the first indication information, and the first terminal device may determine the target resource according to the first indication information and transmit the target resource at an inactive time of DRX according to the first indication information. In another example, the target resource for CLI measurement may be predetermined, such as may be protocol-specified, and the first terminal device may transmit the protocol-specified target resource at an inactive time of DRX according to the first indication information.

Based on the scheme, the first terminal device can determine that the transmission of the target resource is not controlled by the DRX through the indication of the first indication information, the first terminal device can transmit the target resource at the non-active time of the DRX, and the effectiveness of CLI measurement can be improved.

In a possible implementation manner, the first terminal device may further receive second indication information; the second indication information may be used to indicate the active time of the first terminal device in DRX, and the target resource is sent according to the parameter of the cycle. For example, the second indication information may indicate that the first terminal device transmits the target resource at an active time of the DRX and does not transmit the target resource at an inactive time of the DRX.

Based on the scheme, after the CLI measurement is finished, the first terminal device can determine that the sending of the target resource is controlled by the DRX according to the second indication information, can send the target resource at the active time of the DRX and does not send the target resource at the inactive time of the DRX, so that the power consumption of the first terminal device can be saved.

In a second aspect, an embodiment of the present application further provides another communication method. The method may be performed by a first network device in an embodiment of the present application. In the method, a first network device may send a resource configuration; the resource configuration is used to indicate one or more resources. The first network device may also transmit first indication information, which may be used to determine a target resource among the one or more resources. The target resource here may be a periodic SRS resource or a semi-persistent SRS resource. The target resource is a resource transmitted by the first terminal device at an inactive time of the DRX.

Based on the scheme, the first network device may indicate one or more resources to the first terminal device through resource configuration, and may also indicate a target resource for CLI measurement to the first terminal device through the first indication information, so that the first terminal device may send the target resource at the inactive time of DRX, which may improve the validity of CLI measurement.

In one possible implementation, the target resource is also a resource that the first terminal device transmits at an active time of DRX.

Based on the scheme, the first network device may indicate, through the first indication information, that the transmission of the target resource of the first terminal device is not controlled by DRX, so that the first terminal device transmits the target resource at both active time and inactive time of DRX for measurement of CLI.

In a possible implementation manner, the first indication information may be further used to trigger the first terminal device to transmit the target resource at an inactive time of DRX. In one example, the first indication information may indicate the target resource, such that the first terminal device determines the target resource upon receiving the first indication information and transmits the target resource at an inactive time of DRX. In another example, the target resource may be predetermined, such as may be protocol-specified, and the first network device may instruct, through the first indication information, the first terminal device to transmit the protocol-specified target resource at the inactive time of DRX.

Based on the scheme, the first network device can indicate the first terminal device to transmit the target resource in the non-active time of the DRX through the first indication information, and the validity of CLI measurement can be improved.

In a possible implementation manner, the first network device may further send second indication information, where the second indication information may be used to indicate that the first terminal device sends the target resource at the active time of DRX.

Based on the scheme, the first network device may indicate that the transmission of the target resource of the first terminal device is controlled by the DRX with the second indication information, so that the first terminal device transmits the target resource during the active time of the DRX and does not transmit the target resource during the inactive time of the DRX, thereby saving the power consumption of the first terminal device.

In a third aspect, an embodiment of the present application further provides another communication method, where the method may be executed by the second terminal device provided in the embodiment of the present application. In the method, the second terminal device may receive a measurement resource configuration, which may be used to indicate measurement resources. The second terminal device may measure the measurement resource, and the second terminal device may further filter the first target measurement result obtained by the measurement. Wherein the first target measurement may satisfy a first condition. For example, the first condition may include at least one of:

1. the measurement is greater than or equal to a first threshold. The first threshold may be predetermined according to an empirical value, for example, -98dB, and the second terminal device may filter the measurement result if the measurement result obtained by the second terminal device measuring the measurement resource is greater than-98 dB. Alternatively, the first threshold may also be indicated by the second network device, or may also be determined by the second terminal device itself, or may also be specified by a protocol, which is not specifically limited in this application.

2. The difference between the measurement result and the first measurement result is less than or equal to a second threshold. Wherein the first measurement result is a measurement result of a last measurement of the corresponding measurement. For example, if the second terminal device performs one measurement on the measurement resource, which may be referred to as a first measurement, and the second terminal device performs one measurement on the measurement resource, which may be referred to as a second measurement, the measurement result of the first measurement may be a first measurement result. It should be understood that the second threshold may be predetermined according to an empirical value, or may also be indicated by the second network device, or may also be determined by the second terminal device itself, or may also be specified by a protocol, and the present application is not limited specifically.

3. The second terminal device may also receive DRX information of the measurement resource. The first target measurement result may be that the measurement result is measured within an active time of DRX indicated by the DRX information. The activation time of DRX here may be a time including only a DRX Duration Timer (DRX-on Duration Timer) running time. The DRX information of the measurement resource may refer to DRX information of a terminal device that transmits the measurement resource. For example, the measurement resource included in the measurement configuration is a resource transmitted by the third terminal device, and the DRX information of the measurement resource may refer to DRX information of the third terminal device. It should be noted that one measurement resource may correspond to one DRX information, or a plurality of measurement resources may correspond to one DRX information.

Based on the scheme, when the second terminal device filters the measurement result, the measurement result meeting the first condition can be filtered, and the influence of the abnormal measurement result on the CLI measurement can be reduced, so that the influence of DRX on the CLI measurement accuracy can be reduced, and the CLI measurement accuracy can be improved.

In a possible implementation manner, the second terminal device may adjust a filter coefficient, and filter the second target measurement result obtained by the measurement. The second target measurement result here is a measurement result other than the first target measurement result.

Based on the scheme, the second terminal device can adjust the filter coefficient when filtering the second target measurement result, so that the influence of the abnormal measurement result on the CLI measurement can be reduced, and the influence of DRX on the CLI measurement accuracy can be reduced.

In one possible implementation, the second terminal device may further receive DRX information of the measurement resource. The second terminal device may measure the measurement resource within the active time of DRX indicated by the DRX information when measuring the measurement resource. The activation time of DRX here may be a time including only a DRX Duration Timer (DRX-on Duration Timer) running time.

Based on the scheme, the second terminal device only measures the measurement resources at the activation time of the DRX represented by the DRX information, and the influence of the DRX on the accuracy of CLI measurement can be reduced.

In a fourth aspect, an embodiment of the present application further provides another communication method, where the method may be performed by a second network device provided in the embodiment of the present application. In the method, the second network device may send a measurement resource configuration, where the measurement resource configuration includes measurement resources. The second network device may also transmit DRX information of the measurement resources. The measurement resource here may be a resource of a terminal device connected to a third network device, and the DRX information may be DRX information of the terminal device connected to the third network device.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

In the description of the present application, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.

In addition, in the embodiments of the present application, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or implementations. Rather, the term using examples is intended to present concepts in a concrete fashion.

For the convenience of understanding the embodiments of the present application, a communication system applicable to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1 as an example. Fig. 1 shows a schematic diagram of a communication system suitable for the communication method of the embodiment of the present application. As shown in fig. 1, the communication system may include a network device 102 and a terminal device 104, where the network device 102 may be configured with multiple antennas and the terminal device 104 may also be configured with multiple antennas.

It should be understood that network device 102 may also include a number of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, etc.).

In the communication system, network device 102 may communicate with a plurality of terminal devices (e.g., terminal device 104 shown in the figure. network device 102 may communicate with one or more terminal devices similar to terminal device 104.

In the communication system, the network device 102 may send a resource configuration to the terminal device 104, where the resource configuration may include a parameter of a periodicity of the target resource. The terminal device 104 may transmit the target resource according to the parameters of the cycle at the inactive time of DRX.

As shown in fig. 2, the communication system may further include a first network device 202, a second network device 204, and a first terminal device 203 and a second terminal device 205.

The second network device 204 may send a measurement resource configuration to the second terminal device 205, where the measurement resource configuration includes measurement resources. The second network device 204 may further send an indication to the first network device 202, where the indication is used to inform the first network device 202 that the second network device 204 sent the measurement resource configuration to the second terminal device 205, and the measurement resource included in the measurement resource configuration. The first network device 202 may send the resource configuration to the first terminal device after receiving the indication information. The resource configuration may include a target resource. It should be noted that the target resource and the measurement resource may be the same resource or different resources.

It should be understood that the technical solution of the present application may be applied to a wireless communication system, for example, the communication system 100 shown in fig. 1, and the communication system may include at least one network device and at least one terminal device, and the network device and the terminal device may communicate through a wireless air interface. For example, the network device in the communication system may correspond to the network device 102 shown in fig. 1, and the terminal device may correspond to the terminal device 104 shown in fig. 1. Alternatively, the present invention may also be applied to the communication system shown in fig. 2, where the communication system may include at least two network devices and at least two terminal devices, and the network devices and the terminal devices may communicate over a wireless air interface. For example, the network devices in the communication system may correspond to the first network device 202 and the second network device 204 shown in fig. 2, and the terminal devices may correspond to the first terminal device 203 and the second terminal device 205 shown in fig. 2.

At present, Time Division Duplexing (TDD) is a duplex mode for implementing uplink and downlink transmission by time division in a communication system. As shown in fig. 3, in TDD mode, reception (downlink) and transmission (uplink) in a communication system are performed at different times on the same frequency channel, i.e., for a certain channel, the channel is used as an uplink channel for a certain time period, and the channel is used as a downlink channel for another time period.

As shown in fig. 3, in the TDD mode, time resources need to be allocated in both uplink and downlink directions, that is, a network needs to allocate which time period is used for uplink transmission and which time period is used for downlink transmission for a terminal device, and this division of the time resources may be referred to as TDD uplink-downlink matching. Different cells may use different TDD uplink and downlink allocations. As shown in fig. 4, cell 1 and cell 2 use different TDD uplink and downlink allocations.

However, when TDD uplink and downlink ratios between cells of adjacent base stations are different, data transmission in one cell may interfere with data transmission in another cell. As shown in fig. 5, it is assumed that the serving cell of terminal device 1 is cell a under network device a, and the serving cell of terminal device 2 is cell B under network device B. Cell a and cell B are two adjacent cells, terminal device 1 is located at the edge of cell a, terminal device 2 is located at the edge of cell B, and the distance between terminal device 1 and terminal device 2 is smaller. At this time, cross-link interference (CLI) may be generated as follows:

1. from the point of view of the terminal device: terminal device 1 is performing Uplink (UL) transmission, and since terminal device 1 is located at the edge of cell a, in order to ensure that UL data can be normally transmitted to network devices, the transmission power of terminal device 1 for UL transmission may be relatively large. While the terminal device 2 is currently performing Downlink (DL) transmission, since the terminal device 2 is also located at the edge of the cell B, the power of DL data sent by the cell B to the terminal device 2 after path loss or the like to reach the terminal device 2 may be small due to being far from the network device. Therefore, when the UL transmission of the terminal device 1 and the DL transmission of the terminal device 2 are performed simultaneously, the UL transmission of the terminal device 1 may interfere with the DL transmission of the terminal device 2, so that the terminal device 2 cannot correctly receive and decode the DL data transmitted from the cell B.

2. From the perspective of the network device: since the cell B is sending DL data to the terminal device 2, and the terminal device 2 is located at the edge of the cell B, in order to ensure that the DL data can be normally sent to the terminal device 2, the power for sending DL data by the cell B may be large. However, cell a is receiving the UL data sent by terminal device 1, and terminal device 1 is also located at the edge of cell a, and since the distance from the network device is far, the power may be small when the UL data sent by terminal device 1 to cell a reaches cell a after path loss or the like. Therefore, when DL data transmission of cell B and UL data reception of cell a are performed simultaneously, there is a possibility that transmission of cell B interferes with reception of cell a, so that the base station of cell a cannot correctly receive and decode UL data transmitted by terminal apparatus 1.

In order to reduce the impact caused by CLI, the network device may configure CLI measurement for the terminal device, allow the terminal device to measure the configured reference signal, obtain the measurement result of the reference signal and perform layer 3filtering (layer 3filtering), and then report the filtered CLI measurement result. And the network device may coordinate scheduling based on information reported by the terminal device to mitigate CLI. For example, as shown in fig. 4, cell B may configure terminal device 2 to perform CLI measurement, and allow terminal device 2 to measure the reference signal transmitted by terminal device 1 to cell a. Currently, according to the types of reference signals measured by the CLI, there are a distinction between CLI Sounding Reference Signal (SRS) -Reference Signal Received Power (RSRP) measurement and CLI-Received Signal Strength Indicator (RSSI) measurement.

Currently, the SRS may include periodic (periodic) SRS, semi-persistent (semi-persistent) SRS, and aperiodic (aperiodic) SRS. For the periodic SRS and the semi-persistent SRS, the terminal device may periodically transmit the SRS according to parameters configured by the network device. However, both periodic and semi-persistent SRS transmissions need to be controlled by DRX. Specifically, the terminal device may transmit the periodic SRS or the semi-persistent SRS at an active time of the DRX, and may not transmit the periodic SRS or the semi-persistent SRS at an inactive time of the DRX.

However, for SRS resources in CLI SRS-RSRP measurement, because the SRS resources need to be affected by DRX, SRS may not be accurately transmitted according to SRS period, thereby affecting CLI measurement accuracy, and a measurement result reported by a terminal device may also be inaccurate, thereby also possibly causing a situation that a network device erroneously determines interference.

In view of this, the embodiments of the present application provide a communication method, which can be applied to various communication systems, for example: long Term Evolution (LTE) system, Worldwide Interoperability for Microwave Access (WiMAX) communication system, future fifth Generation (5th Generation, 5G) system, such as new radio access technology (NR), and future communication system, such as 6G system.

This application is intended to present various aspects, embodiments or features around a system that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

The embodiment of the application can be applied to a traditional typical network, and can also be applied to a future UE-centric (UE-centric) network. A UE-centric network introduces a network architecture without a cell (Non-cell), that is, a large number of small stations are deployed in a certain area to form a super cell (super cell), each small station is a Transmission Point (TP) or a Transmission and Reception Point (TRP) of the super cell, and is connected to a centralized controller (controller). When the UE moves in the Hyper cell, the network equipment selects a new sub-cluster for the UE to serve, thereby avoiding real cell switching and realizing the continuity of UE service. Wherein the network device comprises a wireless network device. Or, in a network with UE as the center, multiple network devices, such as small stations, may have independent controllers, such as distributed controllers, each small station may independently schedule users, and there is interaction information between small stations over a long period of time, so that there is also a certain flexibility when providing cooperative service for UE.

In the embodiment of the present application, different base stations may be base stations with different identities, or base stations with the same identity and deployed in different geographic locations. Before the base station is deployed, the base station does not know whether the base station relates to a scene to which the embodiments of the present application are applied. It is to be understood that the aforementioned base stations with different identities may be base station identities, cell identities, or other identities.

Some scenarios in the embodiment of the present application are described by taking a scenario of an NR network in a wireless communication network as an example, it should be noted that the scheme in the embodiment of the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.

Fig. 6 is an exemplary flowchart of a communication method provided by an embodiment of the present application, shown from the perspective of device interaction. As shown in fig. 6, the method may include:

step 601: the first network device sends the resource configuration to the first terminal device.

Wherein the resource configuration may include parameters of a periodicity of the target resource. The target resource here may be at least one of a periodic SRS and a semi-persistent SRS. The first terminal device may determine the target resource among the one or more resources indicated in the resource configuration. The following method for determining a target resource by a first terminal device is specifically described, and may include the following method 1 to method 3:

the method comprises the following steps: the first terminal device may determine the target resource according to the resource configuration.

The resource configuration herein may include one or more resource sets, and each resource set may include one or more resources.

When sending the resource configuration, the first network device may indicate the target resource by naming the resource set in the resource configuration, or may indicate the target resource by naming the resource. For example, when the resource set includes "CLI" in its name, the resources in the resource set may be considered as target resources, and when the resource set includes "CLI" in its name, the resource may be considered as target resources.

For example, the resource configuration sent by the first network device includes multiple resource sets, where one of the resource sets is named "CLI SRS resource set", and the first terminal device may consider that the resources included in the resource set are all target resources. Or, the resource configuration sent by the first network device includes resource set 1 and resource set 2. Wherein, 2 resources contained in the resource set 1 are named "CLI SRS resource", 3 resources contained in the resource set 2 are named "CLI SRS resource", and the first terminal device may determine 5 resources named "CLI SRS resource" as target resources.

The method 2 comprises the following steps: the first terminal device may determine the target resource according to the resource configuration and the first indication information.

In one embodiment, the resource configuration may also include an identification of the resource set, or an identification of the resource. For example, the resource configuration includes 2 resource sets, which are resource set 1 and resource set 2. Alternatively, the resource configuration includes a resource set, and the resource set includes resource 1, resource 2, and resource 3. The first terminal device may determine the target resource from the resources indicated by the resource configuration according to the first indication information. The first indication information here may comprise an identification of the target resource or may comprise an identification of the set of resources. Wherein the first indication information may be transmitted by the first network device. When the first network device sends the first indication information, the first indication information may be sent simultaneously with the resource configuration or separately from the resource configuration. In an example, the first network device may send the first indication information carried in the resource configuration to the first terminal device.

For example, the resource configuration received by the first terminal device includes resource set 1, resource set 2, and resource set 3. The first terminal device receives the first indication information again, where the first indication information includes the resource set 1, and then the first terminal device may determine that the resources in the resource set 1 are all target resources. Or, the resource configuration received by the first terminal device includes resource 1, resource 2, resource 3, and resource 4. The resource configuration further includes first indication information, where the first indication information includes resource 1 and resource 2, and the first terminal device may determine that resource 1 and resource 2 are target resources.

In another embodiment, first indication information may be added to the resource configuration, and the first indication information may be used to indicate whether the resource set is a resource set of the target resource, or the first indication information may be used to indicate whether the resource is the target resource. For example, if the relevant configuration information of the resource set includes the first indication information, the resources in the resource set are all target resources, and if the relevant configuration information of the resources includes the first indication information, the resources are the target resources.

For example, the resource configuration received by the first terminal device includes a resource set 1 and a resource set 2, the configuration information related to the resource set 1 includes the first indication information, and the configuration information related to the resource set 2 does not include the first indication information. Then, the first terminal device may determine that the resources in the resource set 1 are all target resources. Alternatively, the resource configuration received by the first terminal device includes resource 1, resource 2, and resource 3, the configuration information related to resource 1 and resource 3 includes the first indication information, and the configuration information related to resource 2 does not include the first indication information. Then the first terminal device may determine that resource 1 and resource 3 are target resources.

In one example, the first indication information may be 1 bit (bit) information. For example, when the bit is "1", it may be indicated that the resource included in the resource set is the target resource, or that the resource is the target resource. When the bit is "0", it can be identified that the resource contained in the resource set is not the target resource, or the resource is not the target resource.

For example, the resource configuration received by the first terminal device includes a resource set 1 and a resource set 2, the related configuration information of the resource set 1 includes "1", and the related configuration information of the resource set 2 includes "0". Then, the first terminal device may determine the resource contained in the resource set 1 as the target resource. Alternatively, the resource configuration received by the first terminal device includes resource 1, resource 2, and resource 3, and the configuration information related to resource 1 includes "1", the configuration information related to resource 2 includes "1", and the configuration information related to resource 3 includes "0". The first terminal device may determine that resource 1 and resource 2 are the target resources.

The method 3 comprises the following steps: the first terminal device may determine the target resource according to the specification of the protocol and the first indication information.

The protocol herein may be a protocol like the third generation partnership project protocol. The target resource of the first terminal device may be specified in the protocol. For example, a type of the target resource may be specified, e.g., both the periodic SRS and/or the semi-persistent SRS may be specified as the target resource. The first indication information may be indication information for triggering the first terminal device to transmit the target resource.

For example, if the first terminal device receives the first indication information sent by the first network device, the first terminal device may determine, in resources already configured by the first network device, that all periodic SRS and/or semi-persistent SRS are target resources, and send the periodic SRS and/or the semi-persistent SRS.

In this embodiment, the first network device may further send the resource configuration or the first indication information to the first terminal device according to the indication of the second network device. As shown in fig. 2, the second network device 204 may send first information to the first network device 202 for instructing the second network device 204 to send the measurement resource configuration to the second terminal device 205. The first indication may include the measurement resources indicated by the second network device 204 to the second terminal device 205. The first network device 202 may send the resource configuration or the first indication information to the first terminal device 203 according to the first information.

Step 602: and the first terminal equipment transmits the target resource according to the periodic parameters in the non-active time of the DRX.

The first terminal device may determine the periodicity of the target resource according to the parameter of the periodicity. The parameter of the period may be an identifier of the period, for example, 1 may be used to represent a period with a duration of 1s, and 2 may be used to represent a period with a duration of 2 s. Alternatively, the parameter of the period may be a duration, such as 1s or 1.5 s.

In one embodiment, the first terminal device may maintain a timer, and may start timing when receiving the resource configuration or the first indication information. For example, when the resource configuration indicates one or more resources, the first terminal device may start timing when receiving the first indication information, and send the target resource and reset the timer when the timing duration reaches the duration of the period of the target resource. Alternatively, when the resource configuration indicates the target resource, the first terminal device may start timing when receiving the resource configuration, and send the target resource and reset the timer when the timing duration reaches the duration of the period of the target resource.

In another embodiment, the first terminal device may calculate the time point of transmitting the target resource according to the parameter of the period. For example, the target resource can be calculated from the parameters, which slots (slots) of which frames (frames) are transmitted.

As shown in FIG. 7, the first terminal device enters DRX mode at time t1, where t1-t2 are active time of DRX and t2-t3 are inactive time of DRX. The first terminal device may transmit the target resource according to the periodic parameter within t2-t 3.

In this embodiment, the first terminal device may further send the target resource at the active time of DRX. As shown in FIG. 8, the first terminal device enters DRX mode at time t1, where t1-t2 are active time of DRX and t2-t3 are inactive time of DRX. At time T1, the period of target resource 1 expires, and the first terminal device may transmit the target resource at time T1. The period of target resource 1 again expires at time T2, and the first terminal device may transmit the target resource at time T2.

Based on the scheme, the first terminal device can not be controlled by DRX when sending the target resource, can send the target resource at the active time or the inactive time of the DRX, and can improve the accuracy of CLI measurement.

In this embodiment of the present application, the method may further perform step 603, where the second terminal device measures the target resource. The second terminal device may perform CLI measurement according to the measurement resource configuration of the second network device, and measure the target resource sent by the first terminal device. The second terminal device may filter the measurement result and send the filtered measurement result to the second network device.

In one embodiment, the first network device may send the second indication information to the first terminal device. The second indication information is used for indicating the activation time of the first terminal equipment in DRX and sending the target resource according to the parameter of the period. As shown in fig. 9, at time t1, the first terminal device receives the second indication information sent by the first network device. The period of the target resource 1 expires at time T1, at time T1 at the active time for DRX, the first terminal device transmits the target resource 1 at time T1. The first terminal device target resource 1 cycle again expires at time T2, but at time T2 at the inactive time of DRX, the first terminal device does not transmit target resource 1 at time T2.

In one example, the first network device may send the second indication information to the first terminal device upon receiving the second information sent by the second network device. The second information may be for notifying the first network device that the CLI measurement configured by the second network device to the second terminal device has ended. The second information may be used to trigger the first network device to send second indication information to the first terminal device. As shown in fig. 2, the second terminal device 205 performs CLI measurement according to the measurement resource configuration transmitted by the second network device 204. The second network device 204 may send the second information to the first network device 202 after the second terminal device 205 finishes CLI measurement. When receiving the second information, the first network device 202 may send second indication information to the first terminal device 203.

In this embodiment of the application, the second information may further include measurement resources indicated by the second network device to the second terminal device, and may be used to indicate which measurement resources related to CLI measurement have ended. Therefore, when the first network device receives the second information and sends the second indication information to the first terminal device, the measurement resource included in the second information may be carried in the second indication information. The first terminal device may transmit the measurement resource included in the second indication information at the active time of DRX according to the second indication information.

Based on the scheme, when CLI measurement is finished, the first terminal device sends the target resource under the control of DRX, and the first terminal device can send the target resource at the activation time of DRX, so that the power consumption of the first terminal device can be saved.

The embodiment of the application also provides another communication method. The communication method may be applied to a communication system as shown in fig. 1. In the communication system, the network device 102 may send a measurement resource configuration to the terminal device 104, where the measurement resource configuration includes measurement resources. The terminal device 104 may measure the measurement resource to obtain a measurement result. Terminal device 104 may filter the measurements and send the filtered measurements to network device 102.

Fig. 10 is an exemplary flowchart of a communication method provided by an embodiment of the present application, shown from the perspective of device interaction. Wherein the second terminal device may be the terminal device 104 shown in fig. 1, and the second network device may be the network device 102 shown in fig. 1. As shown in fig. 10, the following steps may be included:

step 1001: and the second network equipment sends the measurement resource configuration to the second terminal equipment.

The measurement resource configuration herein may include measurement resources. For example, the measurement resource configuration may include an identifier of the measurement resource, or time domain configuration information and frequency domain configuration information of the measurement resource.

Step 1002: and the second terminal equipment measures the measurement resource.

Wherein the second terminal device may perform CLI SRS-RSRP measurement on the measurement resource. The following method for measuring the measurement by the second terminal device is specifically described, and may include the following measurement method 1 and measurement method 2:

measurement method 1: the second terminal device may measure the measurement resources at the active time of DRX.

The activation time of DRX here may be a time including only a DRX Duration Timer (DRX-on Duration Timer) running time.

In one embodiment, the second terminal device may receive DRX information of the measurement resource transmitted by the second network device. The DRX information of the measurement resource here may be DRX information of the first terminal apparatus which transmits the measurement resource. The first terminal device may be a terminal device connected to the first network device. It should be understood that the second network device may obtain DRX information of the first terminal device from the first network device and send the DRX information to the second terminal device. The second terminal device may measure the measurement resource at the active time indicated by the DRX when measuring the measurement resource.

As shown in fig. 2, the second network device 204 may request DRX information of the first terminal device 203 from the first network device 202. The first network device 202 may send the DRX information of the first terminal device 203 to the second network device 204, and the second network device 204 may send the DRX information of the first terminal device 203 to the second terminal device 205. The second terminal device 205 determines the active time of the first terminal device 203 according to the DRX information, and measures the measurement resource at the active time.

It should be understood that the DRX information in the embodiments of the present application may be that one measurement resource corresponds to one DRX information, or that a plurality of measurement resources correspond to one DRX information. For example, it may be that measurement resource 1 corresponds to DRX information 1, and measurement resource 2 and measurement resource 3 correspond to DRX information 2. The second terminal device may measure the measurement resource 1 at the active time indicated by the DRX information 1, and measure the measurement resource 2 and the measurement resource 3 at the active time indicated by the DRX information 2.

In one example, a parameter of a periodicity of the measurement resources is also included in the measurement resource configuration. The second terminal device may measure the measurement resource according to the parameter of the cycle of the measurement resource and the DRX information. The parameter of the period here may be an identification of the period or may also be a duration of the period. In one embodiment, the second terminal device may maintain a timer, start timing when receiving the resource allocation, and stop timing when the timing duration reaches the duration of the measurement period. The second terminal device may measure the measurement resource when the timing duration reaches the duration of the measurement period, and reset the timer. In another embodiment, the second terminal device may calculate a time point for measuring the measurement resource according to the periodic parameter. For example, it can be calculated from the parameters on which time slots the measurement resources are measured.

It should be understood that if it is determined from the parameters of the cycle that the time point at which the measurement resource is measured is at the inactive time of DRX, the second terminal device may not measure the measurement resource at the time point. If it is determined from the parameters of the cycle that the time point of measuring the measurement resource is at the active time of DRX, the second terminal device may measure the measurement resource at the time point.

For example, the measurement resource configuration received by the second terminal device includes measurement resource 1, and the period of the measurement resource 1 is 1. As shown in FIG. 11, t1-t3 is a DRX cycle, where t1-t2 are active times and t2-t3 are inactive times. The measurement period for measurement resource 1 expires at time T1, and at active time for DRX at time T1, the second terminal device may measure measurement resource 1 at time T1. The measurement period for measuring resource 1 again expires at time T2, but at time T2 is at inactive time for DRX, so the second terminal device may not measure measurement resource 1 at time T2.

Measurement method 2: the second terminal device measures the measurement resources at active and inactive times of the DRX.

The second terminal device may measure the measurement resource according to the periodic parameter of the measurement resource. The parameter of the period here may be an identification of the period or may also be a duration of the period. In one embodiment, the second terminal device may maintain a timer, start timing when receiving the resource allocation, and stop timing when the timing duration reaches the duration of the measurement period. The second terminal device may measure the measurement resource when the timing duration reaches the duration of the measurement period, and reset the timer. In another embodiment, the second terminal device may calculate a time point for measuring the measurement resource according to the periodic parameter. For example, it can be calculated from the parameters on which time slots the measurement resources are measured.

For example, the measurement resource configuration received by the second terminal device includes measurement resource 1 and cycle 1 of measurement resource 1. As shown in fig. 12, when the measured duration reaches the measurement period at time T1, the second terminal device may measure measurement resource 1 at time T1 and reset the timer. The timing duration reaches the measurement period at time T2, and the second terminal device may measure measurement resource 1 at time T2 and reset the timer.

Step 1003: and the second terminal equipment filters the measurement result.

Wherein the second terminal device may perform layer 1 filtering or layer 3filtering on the measurement result. The following describes a filtering method of the second terminal device, which may include method 1 and method 2:

the filtering method 1: the second terminal device filters the first target measurement result.

The first target measurement result here may be a measurement result satisfying a first condition. Wherein the first condition may include the following condition 1-condition 3:

condition 1: the measurement is greater than or equal to a first threshold.

For example, after the second terminal device measures the measurement resource, if the obtained measurement result is greater than or equal to the first threshold, the second terminal device may filter the measurement result. The second terminal device may not use the measurement result if the obtained measurement result is smaller than the first threshold value.

The first threshold may be predetermined according to an empirical value, or may be indicated by the second network device, or may be specified by a protocol, or may be determined by the second terminal device itself, and the present application is not limited specifically.

Condition 2: the difference between the measurement result and the first measurement result is less than or equal to a second threshold.

The first measurement result here is a measurement result of a last measurement of a measurement corresponding to the measurement result. As shown in fig. 13, the second network device measures the measurement resource at time T1, and the second terminal device also measures the measurement resource at time T2. Then, the measurement at time T1 may be the first measurement. The value of the measurement result at the time T1 may be the value of the measurement result obtained by measurement, or may be the value obtained by filtering the measurement result. The second terminal device may filter the measurement result measured at the time T2 if the difference between the measurement result measured at the time T2 and the measurement result measured at the time T1 is less than or equal to a second threshold value. The second terminal device may not use the measurement result measured at the time T2 if the difference between the measurement result measured at the time T2 and the measurement result measured at the time T1 is greater than the second threshold value.

The second threshold may be predetermined according to an empirical value, or may be indicated by the second network device, or may be specified by a protocol, or may be determined by the second terminal device itself, and the present application is not particularly limited.

Condition 3: the measurement result is measured within the active time of DRX indicated by the DRX information.

As shown in fig. 11, the second terminal device may filter the measurement result if the measurement result is measured at t1-t2, and may not use the measurement result if the measurement result is measured at t2-t 3.

The filtering method 2 comprises the following steps: the second terminal device filters the first target measurement result and the second target measurement result.

Here, the first target measurement result is a measurement result satisfying a first condition, and the first condition may be as described in the above condition 1 to condition 3, and is not described here again. The second target measurement may be a measurement other than the first target measurement.

If the second terminal device measures the measurement resource to obtain a first target measurement result, the second terminal device may filter the first target measurement result, and if the second terminal device measures the measurement resource to obtain a second target measurement result, the second terminal device may adjust a filter coefficient and filter the second target measurement result according to the adjusted filter coefficient. As shown in fig. 13, the second terminal device measures the measurement resource at time T1 to obtain a first target measurement result, the second terminal device may filter the first target measurement result, and the second terminal device measures the measurement resource at time T2 to obtain a second target measurement result, and the second terminal device may filter the second target measurement result after adjusting the filter coefficient. By analogy, if the second terminal device measures the measurement resource at the time T3 to obtain the first target measurement result, the filter coefficient used by the second terminal device during filtering may be the same as the filter coefficient of the measurement result at the time T1; if the second terminal device measures the measurement resource at the time T4 to obtain a second target measurement result, the filter coefficient used by the second terminal device during filtering may be the same as or different from the filter coefficient of the measurement result at the time T2, and the second terminal device may specifically adjust the filter coefficient according to the value of the second target measurement result.

It should be understood that, in the embodiment of the present application, the filter coefficient when the first target measurement result is filtered and the filter coefficient when the second target measurement result is filtered may be indicated by the second network device, or may also be specified by a protocol, or may also be determined by the second terminal device itself, which is not specifically limited in the present application.
