In some embodiments, when the first terminal performs a sidelink communication via a beam, In the environment, there may also be a network device communicating with the second terminal via a beam. In this case, the beam used by the first terminal may affect the communication between the network device and the second terminal.

FIG. 2 is a schematic diagram of a communication scenario according to an embodiment of the present disclosure.

As shown in Figure 2, the first terminal UE#1 communicates with the third terminal UE#3 via a direct link, and the network device (e.g., gNB) communicates with the second terminal UE#2 (e.g., via the Uu port).

UE#1 can communicate with UE#3 via a direct link through a beam. For example, UE#1 can send information to UE#3 via beam beam#1. The gNB can receive information sent by UE#2 via beam b#1.

In this case, beam#1 of UE#1 may cause strong interference to b#1 of gNB. For example, in a scenario where UE#1 communicates with gNB via beams, UE#1 may use two beams, beam#1 and beam#2, to communicate with gNB, and gNB may use four beams, b#1, b#2, b#3, and b#4, to communicate with UE#1. UE#1 may measure these four beams to determine the beam with the best signal quality corresponding to these four beams when using beam#1, such as b#1, and determine the beam with the best signal quality corresponding to these four beams when using beam#2, such as b#2.

That is to say, when UE#1 communicates with gNB using beam#1, the communication quality is best when gNB uses b#1. Correspondingly, when gNB uses b#1 to communicate with UE#1, the signal quality received from UE#1 using beam#1 is best.

However, when UE#1 is using beam#1 to send information and gNB is using b#1 to receive information, but UE#1 is not communicating with gNB, but UE#1 is using beam#1 to send information to UE#3, and gNB is using b#1 to receive information sent by UE#2, then beam#1 of UE#1 will cause relatively large interference to b#1 of gNB, thereby affecting the communication quality between gNB and UE#2.

FIG3A is an interactive schematic diagram showing an indication receiving method according to an embodiment of the present disclosure.

As shown in FIG3A , the indication receiving method may include the following steps:

In step S301, a first terminal sends first indication information to a network device.

In some embodiments, the network device receives first indication information sent by the first terminal.

In some embodiments, the first indication information is used to indicate at least one of the following:

When the first terminal uses the first beam for direct link communication, at least one second beam among the available receiving beams for communication between the network device and the second terminal that is relatively more interfered by the first beam;

When the first terminal uses the first beam for direct link communication, the network device uses at least one third beam in the receiving beams available for communication with the second terminal and which is relatively less interfered by the first beam.

In some embodiments, the first terminal may measure the beam of the network device when using the first beam to determine the communication quality of the network device using each beam to communicate with the first terminal when the first terminal uses the first beam. The first terminal may generate first indication information based on the measurement result and send the first indication information to the network device.

For example, the network device can use n beams to communicate with the first terminal. When using the first beam beam#1, the first terminal can measure the n beams of the network device to obtain n measurement results corresponding to the n beams. The first terminal can report the measurement results to the network device. Based on this, the network device can determine the communication quality ranking corresponding to each of the n beams used by the network device when the first terminal uses beam#1 to communicate. For example, the beam with the best communication quality among the n beams is the i-th beam, where i and n are positive integers and i is less than or equal to n.

Correspondingly, when the first terminal uses beam#1 to communicate with the third terminal in a direct link, and the network device uses a beam to communicate with the second terminal, among the n beams used by the network device, the beam with a relatively high communication quality ranking (that is, relatively good communication quality) is relatively more interfered by beam#1.

In some embodiments, the beam of the network device may carry at least one of the following:

Synchronization signal and Physical downlink broadcast channel block (SSB), Channel State Information Reference Signal (CSI-RS)

For example, the first terminal may measure the SSB in each beam, and when the first terminal uses beam#1 for communication, the network device uses the communication quality corresponding to each of the n beams to rank them. For example, the first terminal may measure the CSI-RS in each beam, and when the first terminal uses beam#1 for communication, the network device uses the communication quality corresponding to each of the n beams to rank them.

In some embodiments, the synchronization broadcast signal block index is associated with a receiving beam of the network device; and/or the channel state information reference signal resource identifier is associated with a beam of the network device.

For example, the first indication information may include a synchronized broadcast signal block index (SSB index), or the first indication information may include a channel state information reference signal identifier (CSI-RS resource ID). Since the SSB index and the CSI-RS resource ID may be associated with a beam, the network device may determine, based on the first indication information, the communication quality corresponding to each of the n beams used by the network device when the first terminal uses beam#1, and correspondingly, the order in which each of the n beams used by the network device receives interference from beam#1 when the first terminal uses beam#1 for direct link communication.

For example, if n=5, the network device can use 5 beams to communicate with the second terminal, and the 5 beams are b#1, b#2, b#3, b#4, and b#5. According to the measurement results, the network device can determine that when the first terminal uses beam#1 to communicate with the network device, the communication quality of the beams used by the network device is b#2, b#1, b#3, b#4, and b#5 from high to low, and further determine that when the terminal uses beam#1 for direct link communication, the interference of beam#1 in the 5 beams is b#2, b#1, b#3, b#4, and b#5 from large to small.

In some embodiments, at least one second beam with relatively large interference may be a beam whose corresponding communication quality is greater than a first quality threshold among the n beams; and at least one third beam with relatively small interference may be a beam whose corresponding communication quality is less than a second quality threshold among the n beams. The first quality threshold is greater than or equal to the second quality threshold.

In some embodiments, at least one second beam with relatively large interference may be a beam with corresponding interference (for example, determined according to the communication quality corresponding to the beam, and positively correlated with the communication quality corresponding to the beam) greater than a first interference threshold among the n beams; at least one third beam with relatively small interference may be a beam with corresponding interference less than a second interference threshold among the n beams. The first interference threshold is greater than or equal to the second interference threshold.

In some embodiments, at least one second beam with relatively large interference may be a beam that is relatively ranked higher (for example, ranked in the top L positions) among the n beams in terms of interference received by the first beam; at least one third beam with relatively small interference may be a beam that is relatively ranked lower (for example, ranked in the bottom L positions) among the n beams in terms of interference received by the first beam.

In some embodiments, in order to save overhead, when reporting measurement results, the first terminal need not report all n measurement results to the network device, but only needs to report L measurement results out of the n measurement results. Among them, L can be configured by the network device or determined based on protocol agreement, and the present disclosure does not limit this.

For example, the first terminal may report L measurement results with the worst communication quality among the n measurement results.

Still taking the 5 beams in the above embodiment as an example, for example L=2, the first indication information includes the CSI-RS resource ID.

For example, the first terminal can report L measurement results with the best communication quality among n measurement results, then the measurement results corresponding to b#2 and b#1 can be sent to the network device. For example, the CSI-RS resource ID associated with b#2 is CSI-RS resource#2, and the CSI-RS resource ID associated with b#1 is CSI-RS resource#1. The first terminal can carry CSI-RS resource#2 and CSI-RS resource#1 in the first indication information and send it to the network device.

For example, the first terminal can report L measurement results with the worst communication quality among n measurement results, then the measurement results corresponding to b#4 and b#5 can be sent to the network device. For example, the CSI-RS resource ID associated with b#4 is CSI-RS resource#4, and the CSI-RS resource ID associated with b#5 is CSI-RS resource#5. The first terminal can carry CSI-RS resource#4 and CSI-RS resource#5 in the first indication information and send it to the network device.

For example, L CSI-RS resource#IDs may be located at a specific position in the first indication information so that the network device can determine the communication quality ranking of the beam corresponding to each CSI-RS resource#ID in the L CSI-RS resource#IDs. For example, the determined ranking may be in ascending order of communication quality, or may be in descending order of communication quality.

It should be noted that the first indication information may also indicate the beam used by the first terminal for direct link communication, such as the first beam mentioned above.

In step S302, the network determines, based on the first indication information, the beam that the network device needs to use to communicate with the second terminal when the first terminal uses the first beam for direct link communication.

According to an embodiment of the present disclosure, the network device can determine, based on the first indication information reported by the first terminal, the beam required for communication between the network device and the second terminal when the first terminal uses the first beam for direct link communication. Accordingly, it is easy to ensure that the network device can select a beam with relatively less interference from the first beam to communicate with the second terminal, which is beneficial to ensuring the communication quality between the network device and the second terminal.

The following uses several embodiments to exemplify the beam required for communication between the network device and the second terminal when the network device uses the first beam for direct link communication at the first terminal according to the first indication information.

In some embodiments, the first indication information is used to indicate at least one second beam, and the network device can determine in the receiving beam other than the at least one second beam: when the first terminal uses the first beam for direct link communication, the beam required for the network device to communicate with the second terminal.

For example, the first indication information may indicate at least one second beam among the receiving beams available for communication between the network device and the second terminal that is relatively more interfered by the first beam when the first terminal uses the first beam for direct link communication.

Taking n=5 and L=2 as an example, at least one second beam may be b#2 and b#1, that is, when the first terminal uses beam#1 for direct link communication, the network device uses b#2 or b#1 to communicate with the second terminal, and the interference from beam#1 will be relatively large. Therefore, the network device can select a beam other than the first beam, for example, determine a beam from beams b#3, b#4, and b#5 for communication with the second terminal. Since the beams in b#3, b#4, and b#5 are relatively less interfered by beam#1, the network device uses the beams in b#3, b#4, and b#5 to communicate with the second terminal, which is conducive to reducing the interference from beam#1 and ensuring good communication quality with the second terminal.

In some embodiments, the first indication information is used to indicate at least one third beam, and the network device can determine that the receiving beam that is least interfered by the first beam in the at least one third beam is: the beam required for the network device to communicate with the second terminal when the first terminal uses the first beam for direct link communication.

For example, the first indication information may indicate that when the first terminal uses the first beam for direct link communication, the network device may indicate at least one third beam among the receiving beams available for communication with the second terminal that is relatively less interfered by the first beam.

Taking n=5 and L=2 as an example, at least one third beam may be b#4 and b#5, that is, when the first terminal uses beam#1 for direct link communication, the network device uses b#4 or b#5 to communicate with the second terminal, and the interference from beam#1 will be relatively small. Therefore, the network device can select a beam in at least one second beam, for example, determine a beam from beams b#4 and b#5 for communication with the second terminal. Since the beams in b#4 and b#5 are relatively less interfered by beam#1, the network device uses any one of beams in b#4 and b#5 to communicate with the second terminal, which is conducive to reducing the interference from beam#1 and ensuring good communication quality with the second terminal.

In some embodiments, the network device may also determine, based on the first indication information, an association between time domain resources and a beam for direct link communication by the first terminal.

In some embodiments, the direct link communication resources of the first terminal may include time domain resources and/or frequency domain resources. The direct link communication resources may be included in a resource pool, and the network device is configured to configure one or more resource pools for the first terminal on the bandwidth part (Bandwidth Part, BWP). The resource pool may be periodic in the time domain, and the specific period may be determined based on the parameter periodResourcePool, and a period may include one or more time slots. The time slots belonging to the resource pool in the period may be determined based on the parameter timeResourcePool. For example, timeResourcePool may indicate the time slots belonging to the resource pool in the period in a bitmap manner, and in the time slots belonging to the resource pool, one or more symbols may be included for direct link communication.

In some embodiments, the beam used by the first terminal for direct link communication may be associated with time domain resources, wherein the time domain resources include at least one of the following: a resource pool and a time slot.

For example, taking the time domain resource including time slots as an example, beam#1 of the first terminal is associated with slot#1, and beam#2 of the first terminal is associated with slot#2. The network device can determine, based on the first indication information, that beam#1 of the first terminal is associated with slot#1, and beam#2 of the first terminal is associated with slot#2.

Accordingly, it is convenient for the network device to appropriately adjust the beam used by the network device to communicate with the second terminal according to the time domain resources associated with the beam used by the first terminal for direct link communication.

For example, in the above embodiment, the terminal uses beam#1 to communicate with the third terminal through a direct link. Since beam#1 is associated with slot#1, the network device can determine that the first terminal uses beam#1 for direct link communication in slot#1, so that when the network device communicates with the second terminal in slot#1, it can choose to use b#3, b#4, or b#5 to communicate with the second terminal. When communicating with the second terminal in slot#2, if it is determined that the first terminal uses beam#2 to communicate with the third terminal through a direct link, since beam#2 is associated with slot#2, the network device can switch to using a beam that is relatively less affected by beam#2 to communicate with the second terminal.

FIG. 4 is a schematic diagram of an application scenario of an indication receiving method according to an embodiment of the present disclosure.

As shown in Figure 4, the network device gNB can use five beams to communicate with the first terminal, and the five beams are b#1, b#2, b#3, b#4, and b#5. The first terminal can use two beams for communication, and the two beams are beam#1 and beam#2.

For example, for beam#1, the first terminal can measure the five beams of the network device separately when using beam#1 to determine the communication quality corresponding to each beam. For example, the communication quality corresponding to the five beams is ranked from high to low as b#2, b#1, b#3, b#4, and b#5.

The first terminal may report to the network device two measurement results with the best communication quality among the five measurement results, namely, the measurement results corresponding to b#2 and b#1, wherein the measurement result corresponding to b#2 may be determined by measuring CSI-RS on CSI-RS resource#2, and the measurement result corresponding to b#1 may be determined by measuring CSI-RS on CSI-RS resource#1. The first terminal may characterize the measurement results corresponding to b#2 and b#1 by reporting two CSI-RS resource IDs: CSI-RS resource#1 and CSI-RS resource#2.

For example, the measurement result can be carried in the first indication information and sent to the network device. According to the first indication information, the network device can determine that the beams that are relatively more interfered by beam#1 of the first terminal are b#2 and b#1. Then, when the first terminal uses beam#1 for direct link communication, the network device can avoid using b#2 and b#1 to communicate with the second terminal. For example, it can select a beam from b#3, b#4, and b#5 for communicating with the second terminal, which is beneficial to ensuring the communication quality with the second terminal.

The communication method involved in the embodiment of the present disclosure may include at least one of step S301 to step S302. For example, step S301 may be implemented as an independent embodiment, step S302 may be implemented as an independent embodiment, and step S303 may be implemented as an independent embodiment. Steps S301+S302 may be implemented as independent embodiments, but are not limited thereto.

In some embodiments, steps S301 and S302 may be performed in an exchanged order or simultaneously.

In some embodiments, step S301 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

In some embodiments, step S302 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

FIG3B is an interactive schematic diagram showing an indication receiving method according to an embodiment of the present disclosure.

As shown in FIG3B , the indication receiving method may include the following steps:

In step S303, the first terminal sends first indication information to the network device.

In some embodiments, the network device receives first indication information sent by the first terminal.

In some embodiments, the first indication information is used to indicate at least one of the following:

When the first terminal uses the first beam for direct link communication, at least one second beam among the available receiving beams for communication between the network device and the second terminal that is relatively more interfered by the first beam;

When the first terminal uses the first beam for direct link communication, the network device uses at least one third beam in the receiving beams available for communication with the second terminal and which is relatively less interfered by the first beam.

In some embodiments, the first terminal may measure the beam of the network device when using the first beam to determine the communication quality of the network device using each beam to communicate with the first terminal when the first terminal uses the first beam. The first terminal may generate first indication information based on the measurement result and send the first indication information to the network device.

For example, the network device can use n beams to communicate with the first terminal. When using the first beam beam#1, the first terminal can measure the n beams of the network device to obtain n measurement results corresponding to the n beams. The first terminal can report the measurement results to the network device. Based on this, the network device can determine the communication quality ranking corresponding to each of the n beams used by the network device when the first terminal uses beam#1 to communicate. For example, the beam with the best communication quality among the n beams is the i-th beam, where i and n are positive integers and i is less than or equal to n.

Correspondingly, when the first terminal uses beam#1 to communicate with the third terminal in a direct link, and the network device uses a beam to communicate with the second terminal, among the n beams used by the network device, the beam with a relatively high communication quality ranking (that is, relatively good communication quality) is relatively more interfered by beam#1.

In some embodiments, the beam of the network device may carry at least one of the following:

Synchronization signal and Physical downlink broadcast channel block (SSB), Channel State Information Reference Signal (CSI-RS)

For example, the first terminal may measure the SSB in each beam, and when the first terminal uses beam#1 for communication, the network device uses the communication quality corresponding to each of the n beams to rank them. For example, the first terminal may measure the CSI-RS in each beam, and when the first terminal uses beam#1 for communication, the network device uses the communication quality corresponding to each of the n beams to rank them.

In some embodiments, the synchronization broadcast signal block index is associated with a receiving beam of the network device; and/or the channel state information reference signal resource identifier is associated with a beam of the network device.

For example, the first indication information may include a synchronous broadcast signal block index (SSB index), or the first indication information may include a channel state information reference signal identifier (CSI-RS resource ID). Since the SSB index and the CSI-RS resource ID may be associated with the beam, the network device may determine the first When the terminal uses beam#1, the network device uses the communication quality corresponding to each of the n beams. Correspondingly, it can determine the order in which the network device receives interference from beam#1 when the first terminal uses beam#1 for direct link communication.

For example, if n=5, the network device can use 5 beams to communicate with the second terminal, and the 5 beams are b#1, b#2, b#3, b#4, and b#5. According to the measurement results, the network device can determine that when the first terminal uses beam#1 to communicate with the network device, the communication quality of the beams used by the network device is b#2, b#1, b#3, b#4, and b#5 from high to low, and further determine that when the terminal uses beam#1 for direct link communication, the interference of beam#1 in the 5 beams is b#2, b#1, b#3, b#4, and b#5 from large to small.

In some embodiments, at least one second beam with relatively large interference may be a beam whose corresponding communication quality is greater than a first quality threshold among the n beams; at least one second beam with relatively small interference may be a beam whose corresponding communication quality is less than a second quality threshold among the n beams. The first quality threshold is greater than or equal to the second quality threshold.

In some embodiments, at least one second beam with relatively large interference may be a beam whose corresponding interference (for example, may be determined based on the communication quality corresponding to the beam and is positively correlated with the communication quality corresponding to the beam) is greater than a first interference threshold among the n beams; at least one second beam with relatively small interference may be a beam whose corresponding interference is less than a second interference threshold among the n beams. The first interference threshold is greater than or equal to the second interference threshold.

In some embodiments, at least one second beam with relatively large interference may be a beam that is relatively ranked higher (for example, ranked in the top L positions) among the n beams in terms of interference received by the first beam; at least one third beam with relatively small interference may be a beam that is relatively ranked lower (for example, ranked in the bottom L positions) among the n beams in terms of interference received by the first beam.

In some embodiments, in order to save overhead, when reporting measurement results, the first terminal need not report all n measurement results to the network device, but only needs to report L measurement results out of the n measurement results. Among them, L can be configured by the network device or determined based on protocol agreement, and the present disclosure does not limit this.

For example, the first terminal may report L measurement results with the worst communication quality among the n measurement results.

Still taking the 5 beams in the above embodiment as an example, for example L=2, the first indication information includes the CSI-RS resource ID.

For example, the first terminal can report L measurement results with the best communication quality among n measurement results, then the measurement results corresponding to b#2 and b#1 can be sent to the network device. For example, the CSI-RS resource ID associated with b#2 is CSI-RS resource#2, and the CSI-RS resource ID associated with b#1 is CSI-RS resource#1. The first terminal can carry CSI-RS resource#2 and CSI-RS resource#1 in the first indication information and send it to the network device.

For example, the first terminal can report L measurement results with the worst communication quality among n measurement results, then the measurement results corresponding to b#4 and b#5 can be sent to the network device. For example, the CSI-RS resource ID associated with b#4 is CSI-RS resource#4, and the CSI-RS resource ID associated with b#5 is CSI-RS resource#5. The first terminal can carry CSI-RS resource#4 and CSI-RS resource#5 in the first indication information and send it to the network device.

For example, L CSI-RS resource#IDs may be located at a specific position in the first indication information so that the network device can determine the communication quality ranking of the beam corresponding to each CSI-RS resource#ID in the L CSI-RS resource#IDs. For example, the determined ranking may be in ascending order of communication quality, or may be in descending order of communication quality.

It should be noted that the first indication information may also indicate the beam used by the first terminal for direct link communication, such as the first beam mentioned above.

In step S304, the network device sends second indication information to the first terminal, wherein the second indication information is used by the first terminal to determine a beam to be used for direct link communication.

According to an embodiment of the present disclosure, when a network device needs to use a beam to communicate with a second terminal, it can send second indication information to a first terminal that needs to perform direct link communication, and instruct the first terminal to use a beam for direct link communication through the second indication information. Accordingly, the first terminal can select a beam for direct link communication according to the second indication information, which is conducive to avoiding the beam used by the first terminal for direct link communication from causing significant interference to the communication process of the second terminal of the network device.

In some embodiments, the network device determines that it is necessary to use a beam in at least one second beam to communicate with the second terminal, and sends second indication information to the first terminal; wherein the second indication information instructs the first terminal to disable the first beam when performing direct link communication.

The network device can first determine the beam required to communicate with the second terminal. Since the network device can determine, based on the first indication information reported by the first terminal, that the use of the first beam by the first terminal for a direct link will cause relatively large interference to the second beam of the network device, if the network device needs to use the second beam to communicate with the second terminal, the network device can prohibit the first terminal from using the first beam for direct link communication through the second indication information, so as to avoid the direct link communication of the first terminal causing excessive interference to the communication between the network device and the second terminal, which is conducive to ensuring good communication quality between the network device and the second terminal.

Among them, after receiving the second indication information, if the first terminal determines that the first beam needs to be disabled, it can choose to use a beam other than the first beam to communicate with the third terminal via a direct link; or, if there is no other available beam other than the first beam, it can suspend direct link communication with the third terminal until the subsequent network device lifts the disablement of the first beam.

In some embodiments, it is determined that it is necessary to switch from using a beam in at least one second beam to communicate with the second terminal to using a beam in at least one third beam, and second indication information is sent to the first terminal; wherein the first terminal indicated by the second indication information releases the disabling of the first beam when performing direct link communication.

The network device does not always use the same beam to communicate with the terminal. When the network device switches from using the second beam to communicate with the second terminal to using the third beam to communicate with the second terminal, since the third beam is relatively less interfered with by the first beam, the network device can instruct the first terminal to release the disabling of the first beam through the second indication information, so that the first terminal can use the first beam for direct link communication.

In some embodiments, the network device may send second indication information to the first terminal before using the beam to communicate with the second terminal. For example, if the network device determines to use the second beam to communicate with the second terminal from slot#n to slot#n+10, the second indication information may be sent to the first terminal before slot#n to instruct the first terminal to prohibit using the first beam for direct link communication.

In a further embodiment, the second indication information sent by the network device to the first terminal may have an indication granularity related to time domain resources, wherein the time domain resources include at least one of the following: a resource pool and a time slot.

For example, taking the time domain resources including time slots as an example, the second indication information sent by the network device to the first terminal can instruct the first terminal to prohibit the use of the first beam for direct link communication in slot#n to slot#n+10.

In some embodiments, the network device may also determine, based on the first indication information, an association between time domain resources and a beam for direct link communication by the first terminal.

In some embodiments, the direct link communication resources of the first terminal may include time domain resources and/or frequency domain resources. The direct link communication resources may be included in a resource pool, and the network device is configured to configure one or more resource pools for the first terminal on the bandwidth part (BWP). The resource pool may be periodic in the time domain, and the specific period may be determined based on the parameter periodResourcePool, and a period may include one or more time slots. The time slots belonging to the resource pool in the period may be determined based on the parameter timeResourcePool. For example, timeResourcePool may indicate the time slots belonging to the resource pool in the period by means of a bitmap, and in the time slots belonging to the resource pool, one or more symbols may be included for direct link communication.

In some embodiments, the beam used by the first terminal for direct link communication may be associated with time domain resources, wherein the time domain resources include at least one of the following: a resource pool and a time slot.

For example, taking the time domain resource including time slots as an example, beam#1 of the first terminal is associated with slot#1, and beam#2 of the first terminal is associated with slot#2. The network device can determine, based on the first indication information, that beam#1 of the first terminal is associated with slot#1, and beam#2 of the first terminal is associated with slot#2.

Accordingly, it is convenient for the network device to appropriately adjust the beam used by the first terminal for direct link communication according to the time domain resources associated with the beam used by the first terminal for direct link communication.

For example, in the above embodiment, since beam#1 is associated with slot#1 and beam#2 is associated with slot#2, the network device can determine that the first terminal uses beam#1 for direct link communication in slot#1, and determines that the first terminal uses beam#2 for direct link communication in slot#2.

When the network device communicates with the second terminal in slot#1, if b#1 or b#2 is used to communicate with the second terminal, since b#1 and b#2 are relatively more interfered by beam#1, the first terminal can be instructed to adjust the beam used for direct link communication, and the terminal can be adjusted to use beam#2 for direct link communication in slot#1.

When the network device communicates with the second terminal in slot#2, if b#1 or b#2 is used to communicate with the second terminal, since b#1 and b#2 are relatively less interfered with by beam#2, there is no need to instruct the first terminal to adjust the beam used for direct link communication. The terminal can continue to use beam#2 for direct link communication in slot#2.

5A and 5B are schematic diagrams of application scenarios of an indication receiving method according to an embodiment of the present disclosure.

As shown in Figure 5A, the network device gNB can use five beams to communicate with the first terminal, and the five beams are b#1, b#2, b#3, b#4, and b#5. The first terminal can use two beams for communication, and the two beams are beam#1 and beam#2.

For example, for beam#1, the first terminal can measure the five beams of the network device separately when using beam#1 to determine the communication quality corresponding to each beam. For example, the communication quality corresponding to the five beams is ranked from high to low as b#2, b#1, b#3, b#4, and b#5.

The first terminal may report to the network device two measurement results with the best communication quality among the five measurement results, namely, the measurement results corresponding to b#2 and b#1, wherein the measurement result corresponding to b#2 may be determined by measuring CSI-RS on CSI-RS resource#2, and the measurement result corresponding to b#1 may be determined by measuring CSI-RS on CSI-RS resource#1. The first terminal may characterize the measurement results corresponding to b#2 and b#1 by reporting two CSI-RS resource IDs: CSI-RS resource#1 and CSI-RS resource#2.

For example, the measurement result can be carried in the first indication information and sent to the network device. The network device can determine that the beams that are relatively interfered with by the beam#1 of the first terminal are b#2 and b#1 according to the first indication information. Then, when the network device needs to use b#2 or b#1 to communicate with the second terminal, it can send a second indication information to the first terminal, and instruct the first terminal to prohibit the use of beam#1 for direct link communication through the second indication information. The first terminal can use beam#2 for direct link communication. Accordingly, it is helpful to avoid the Bohu used by the first terminal causing excessive interference to the communication between the network device and the second terminal, and ensure the communication quality with the second terminal.

As shown in Figure 5B, when the network device needs to switch from using b#2 to communicating with the second terminal to using b#5 to communicate with the second terminal, since the network device can determine based on the first indication information that b#5 is relatively less interfered with by beam#1, it can instruct the first terminal to lift the disabling of beam#1 through the second indication information, so that the first terminal can resume using beam#1 for direct link communication.
