Signal amplifiers are widely used to extend the coverage of cells. For example, the network control relay (Network controlled repeater, NCR) may serve as a relay node, and may forward signals from a base station or a User Equipment (UE) and amplify the signals, thereby achieving the purpose of extending coverage.

Wherein the NCR may receive control from an upstream base station (i.e., a home (donor) base station), i.e., the base station may control transmission parameters of the NCR, e.g., the base station may control the NCR and the base station or the receive/transmit beam between the NCR and the UE, etc.

For example, in the network structure shown in fig. 2, three network nodes are included, and the intermediate network node is an NCR device that includes a terminal module (mobile termination, MT) and a forwarding unit (Fwd). Wherein the MT can establish a connection (i.e., control link) with an upstream base station, the base station transmits control signaling to the NCR through the MT, and can control transmission/reception related parameters (including parameters of power, amplification factor, beam, on/off, etc.) between the NCR and the base station (i.e., backhaul link (BH)) or between the NCR and the UE (i.e., access Link (AL)).

The beam adjustment method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

In a first aspect, referring to fig. 4, a flowchart of a beam adjustment method according to an embodiment of the present application is shown, where the method may include the following steps 401 to 402:

step 401: and the relay equipment acquires the related information of the beam set group of the relay equipment.

In the embodiment of the present application, the beam set group is a group of a set divided by beams formed by the relay device. Wherein one beam set group includes at least one beam set, and one beam set includes at least one beam. Optionally, the beams in the same beam set are formed by the same panel or panel combination, or the beams in the same beam set are formed by the same port or port combination, or the beams in the same beam set are formed by the same transmission channel.

Illustratively, beam set group = { beam set #1, beam set #2}, where the beams in different beam sets come from different panels/ports/transmit channels. Taking Panel as an example, as shown in fig. 5, the forwarding antenna Panel of the NCR node may include several panels, where Panel #1 implements beam set #1 and Panel #2 implements beam set #2.

In addition, the information about the beam set group is used for indicating the information of the beams in the beam set group, and the beam set and the combination condition of the beams in the beam set group. Therefore, from the information about the beam set group, it is possible to determine which beam set and which combination each beam is in.

Step 402: and the relay equipment adjusts the wave beam of the access link according to the related information of the wave beam set group.

Optionally, the beams in the same beam set in the beam set group cannot be used simultaneously, and the beams in different beam sets in the beam set group can be used simultaneously. Illustratively, if the beam set group= { beam set #1, beam set #2}, the beams in beam set #1 cannot be used simultaneously, the beams in beam set #2 cannot be used simultaneously, and the beams in beam set #1 can be used simultaneously with the beams in beam set # 2.

Therefore, when the relay device adjusts the beams of the access link according to the related information of the beam set group, the beams which can be used by the access link can be selected according to the principle that the beams in the same beam set cannot be used simultaneously and the beams in different beam sets can be used simultaneously.

For example, when multiple UEs are scheduled simultaneously, the relay device may then select multiple beams from a different set of beams for transmission of access links between the NCR and the multiple UEs.

It should be noted that, the beams in the same beam set are formed by the same panel or panel combination, or the beams in the same beam set are formed by the same port or port combination, or the beams in the same beam set are formed by the same transmitting channel, while one panel or panel combination forms one beam at the same time, one port or port combination forms one beam at the same time, and one transmitting channel forms one beam at the same time, so that the beams in the same beam set cannot be used at the same time, and the beams in different beam sets can be used at the same time.

As can be seen from the foregoing steps 401 to 402, in the embodiment of the present application, the relay device can obtain the related information of the beam set group of the relay device, so as to adjust the beam of the access link according to the related information of the beam set group. It can be seen that, in the embodiment of the present application, even if a plurality of UEs served by the NCR are simultaneously scheduled, the NCR may adjust the transmission beam of the access link between the NCR and the UEs according to the related information of the beam set group.

The specific manner in which the relay device obtains the relevant information of the beam set group may be the following manner one or the following manner two:

The relay device can report the first auxiliary information to the network side device, so that the network side device generates first indication information based on the first auxiliary information, and then sends the first indication information to the relay device, so that the relay device autonomously determines the beam set group according to the first indication information.

Optionally, the first indication information includes at least one of:

number information of sets in the beam set group;

the number of beams in the set of beams information;

Optionally, after the relay device determines the relevant information of the beam set group, the method further includes:

and the relay equipment sends the relevant information of the beam set group to the network equipment.

After the relay device autonomously determines the beam set, the relay device may report the related information of the beam set group to the network device, so that the network device controls or indicates the beam that the relay device may use based on the related information of the beam set group.

Mode two: the relay device obtains related information of a beam set group of the relay device, including:

and the relay equipment receives the related information of the beam set group sent by the network equipment.

That is, in the embodiment of the present application, the network side device may determine the beam set group, so as to notify the relay device of the information about the beam set group.

Optionally, the relay device receives related information of the beam set group sent by the network side device, including:

The relay equipment reports second auxiliary information to the network equipment;

and the relay equipment receives the related information of the beam set group determined by the network side equipment according to the second auxiliary information.

Wherein the second auxiliary information is used for indicating parameter information of the generated beam set group.

The relay device may report the second auxiliary information to the network device, so that the network device determines the beam set group, and the network device informs the relay device of the information about the beam set group.

Optionally, the first auxiliary information or the second auxiliary information includes at least one of the following:

a-1: number information of sets in the beam set group;

a-15: a beam width of a beam formed by each port of the relay device;

a-16: identification information of the carrier wave;

a-17: cell identification information.

Wherein, in the above item a-1, the number information of the sets in the beam set group may include at least one of a maximum number, a minimum number, and a number range of the sets in the beam set group.

When the first auxiliary information or the second auxiliary information includes the items a-2, a-4, a-5, and a-6, it means that the relay device may report beam set information, such as an ID of Panel1, a set generated by Panel1, the number of beams in each set, and the gain and width of each beam, to the network side device according to the Panel (or port).

When the first auxiliary information or the second auxiliary information includes the foregoing a-3, a-4, a-5, and a-6, it indicates that the relay device may report beam set information to the network side device according to the Panel combination, for example, the forwarding antenna of the NCR has four panels, the base station configures panel#1 and panel#2 as Panel combination 1, configures panel#3 and panel#4 as Panel combination 2, and the NCR may report the beam sets of Panel combination 1 and Panel combination 2 to the base station respectively, that is: the ID of Panel combination 1, the set generated by Panel combination 1, the number of beams per set, the gain and width of each beam; the ID of Panel combination 2, the set generated by Panel combination 2, the number of beams per set, the gain and width of each beam.

It should be noted that, when a beam in a beam set is generated by a panel combination, the gain of the beam in the set is determined by all panels in the panel combination.

As can be seen from the above items a-7 and a-8, the set of reception beams and the set of transmission beams may be reported by the relay device, respectively, or only the set of transmission beams may be reported, and the set of reception beams may be determined by the network side device based on beam diversity (beam correspondence); or only reporting the receiving beam set, and determining a sending beam by the network side equipment based on beam correspondence; here, beam correspondence is, for example: the same beam/spatial filter is used for both transmission and reception.

The "number information of beam set groups" in the above item a-9 may include at least one of the maximum number, the minimum number, and the number range of beam set groups.

When the first auxiliary information or the second auxiliary information includes the a-10, a-11, and a-12, the information indicating that the relay device may report the beam formed by the Panel according to the Panel, for example, the relay device includes two panels, where the gain of the beam formed by panel#1 is y1, and the width is z1; the beam formed by Panel #2 has a gain y2 and a width z2.

When the first auxiliary information or the second auxiliary information includes the a-13, a-14, and a-15, the information indicates that the relay device may report the beam formed by the ports according to the panel, for example, the relay device includes two ports, where the gain of the beam formed by Port #1 is y3, and the width is z3; port #2 forms a beam with a gain y4 and a width z4.

That is, the parameter information of the Panel or the Port of the NCR on the AL link, for example, the Panel number, the beam gain parameter, the beam width parameter, etc. of each Panel, or the Port number, the beam gain parameter, the beam width parameter, etc. of each Port may be reported to the network side device by the NCR.

Optionally, the information related to the beam set group includes at least one of the following:

b-1: the identification of each wave beam in the wave beam set group, the identification of the set to which each wave beam belongs, and the identification of the combination to which the set to which each wave beam belongs;

b-2: the identification of the wave beams in each set in the wave beam set group and the identification of the combination to which each set belongs;

b-3: the identification of the beams in each combination in the beam set group, the identification of each combination;

B-4: the identification of each wave beam in the wave beam set group and the identification of the set to which each wave beam belongs;

b-5: an identification of the beams in each of the sets of beams;

b-6: the identity of the beams in each combination in the set of beams.

For example, there are two beam set groups, where combination 1 includes beam set 1 (including beam A, B), beam set 2 (including beam C, D); combination 2 includes beam set 3 (including beam E, F);

the manner in which the relay device notifies the network side device of the information related to the beam set group, or the manner in which the network side device notifies the relay device of the information related to the beam set group may be at least one of cases one to three as follows:

case one:

beam a, belonging to beam set 1, beam set 1 belonging to combination 1;

beam B, belonging to beam set 1, beam set 1 belonging to combination 1;

beam C, belonging to beam set 2, beam set 2 belonging to combination 1;

beam D, belonging to beam set 2, beam set 2 belonging to combination 1;

beam E, belonging to beam set 3, beam set 3 belonging to combination 2;

beam F belongs to beam set 3, beam set 3 belongs to combination 2.

And a second case:

beam A, B, belonging to beam set 1, beam set 1 belonging to combination 1;

beam C, D, belonging to beam set 2, beam set 2 belonging to combination 1;

beam E, F belongs to beam set 3, beam set 3 belongs to combination 2.

And a third case:

beam A, B, C, D, which is combination 1;

beam E, F belongs to combination 2.

Note that, if the relay device does not support coexistence of a plurality of combinations (for example, the predetermined protocol does not support coexistence of a plurality of combinations, or the relay device itself does not support coexistence of a plurality of combinations), it is not necessary to notify the combination ID. That is, in the case where the relay device does not support coexistence of a plurality of combinations, only one combination can be determined, and in the case where it does not support coexistence, the relevant information of the beam set group can be notified according to at least one of the above-described items B-3 to B-6.

In addition, it should be noted that, the above-mentioned combined identifier is a first configuration identifier for identifying a set of beams; the identification of the set is the identification of a panel forming the beams included in the set, or the identification of the ports forming the beams included in the set, or the second configuration identification for identifying a group of beams; the identification of the beam is a reference signal (Reference Signals, RS) identification, or a third configuration identification (e.g., transmission configuration indication (Transmission Configuration Indicator, TCI)) for identifying the beam.

Optionally, before the relay device adjusts the beam of the access link according to the related information of the beam set group, the method further includes:

the relay device receives beam indication information sent by the network side device, wherein the beam indication information comprises at least one beam identifier.

The identification of the beam may include at least one of a beam number and an RS number associated with the beam.

Here, whether the beam set group is determined by the relay device or the network side device, the relay device may transmit the beam indication information to the relay device. I.e. the network side device may control the beam of the access link of the relay device, e.g. the beam number/associated RS number indicating the reception/transmission of the access link by means of the beam indication information, the relay device may adjust the beam of the access link according to the indication of the beam indication information. Further, in the embodiment of the present application, the relay device may adjust the beam of the access link according to the beam indication information and the related information of the beam set group, so as to implement multi-beam simultaneous transmission.

The following further describes a specific implementation manner in which the relay device adjusts the beam of the access link according to the beam indication information and the related information of the beam set group, so as to realize simultaneous transmission of multiple beams.

Optionally, the relay device adjusts a beam of an access link according to the related information of the beam set group, including:

in the case that the first type of beam exists among the beams indicated by the candidate beam indication information, the relay device performs one of the following:

adjusting one of the first type of beams to be a beam of the access link;

adjusting one beam indicated by the beam indication information closest to the current moment in the first type of beams to be the beam of the access link;

adjusting one beam indicated by the beam indication information with the highest priority in the first type of beams to be the beam of the access link;

the candidate beam indication information comprises at least one beam indication information, and the beam indication information contained in the candidate indication information indicates beams at the same moment; the first type of beams are beams belonging to the same set of beams.

For example, the beam indication information M1 is received in the slot (slot) 1, the beam indication information M2 is received in the slot2, both of which indicate the beam case of the slot10, and the beams indicated by the M1 are the beam a and the beam C; the beams indicated by M2 are beam B, beam D and beam E; if beam a and beam B belong to the same set of beams, and beam C and beam D belong to the same set, then one of the following may be used as the beam for the access link:

Any of the beams A, B;

any of the beams C, D;

among the beams A, B, or the beam C, D, the one of the beam whose time indicated by the beam indication information is closest to the current time (for example, the time of M1 is closest to the current time among M1 and M2, beam a is selected from the beams A, B, or beam C is selected from the beams C, D);

among the beams A, B, or one of the beams C, D indicated by the beam indication information of the highest priority (e.g., M1 and M2, with the priority of M2 being the highest), beam B is selected from the beams A, B, and beam D is selected from the beams C, D.

In addition, it should be noted that the priority of the beam indication information may be determined according to at least one of the following:

c-1: time domain granularity of beam indication information;

c-2: a corresponding specific transmission;

c-3: whether it is a dynamic indication determination.

I.e. the priority of the beam indication information with finer time domain granularity is higher, for example, the network side device can indicate the beam information of each slot and also indicate the beam information on each symbol (symbol), and the priority of the beam indication information of the latter is higher in the two cases;

beam indication information corresponding to the specific transmission has a higher priority than beam indication information corresponding to the non-specific transmission; wherein the specific transmission is configured for protocol conventions/network sides; in addition, the specific transmission is, for example, at least one of:

Channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS) transmission;

sounding reference signal (Sounding Reference Signal, SRS) transmission;

physical downlink control channel (physical downlink control channel, PDCCH) transmission;

presetting PDCCH transmission on physical resources (CORESET);

PDCCH transmission on CORESET # 0;

physical uplink control channel (physical uplink control channel, PUCCH) transmission;

-a synchronization signal block (Synchronization Signal Block, SSB) transmission;

physical random access channel (Physical Random Access Channel, PRACH) transmission.

The beam pointing information belonging to the dynamic indication has a higher priority than the beam pointing information belonging to the non-dynamic indication, for example, the beam pointing information is transmitted by downlink control information (Downlink Control Information, DCI) and the beam pointing information is transmitted by radio resource control (Radio Resource Control, RRC).

In addition, for the priority levels of the above-mentioned C-1 to C-3 items, it may be predetermined that, for example, the C-2 item is highest, the C-3 item is next highest, and finally, the C-1 item, that is, for a plurality of beam indication information indicating beams at the same time, the plurality of beam indication information may be sorted in order of gradually decreasing priority levels of the above-mentioned C-2, C-3, C-1 items, in combination with the above-mentioned contents, so that the highest priority beam indication information may be selected.

in the case that the second type of beam exists in the beams indicated by the candidate beam indication information, the relay device performs one of the following:

d-1: adjusting one of the second type of beams to be a beam of the access link;

d-2: adjusting one beam indicated by the beam indication information closest to the current moment in the second type of beams to be the beam of the access link;

d-3: adjusting one beam indicated by the beam indication information with the highest priority in the second type of beams to be the beam of the access link;

d-4: adjusting a plurality of beams in the second type of beams to beams of the access link;

d-5: according to a preset condition or received second indication information, one or more beams in the second type of beams are adjusted to be the beams of the access link, and the second indication information indicates that one or more beams are adopted;

the candidate beam indication information comprises at least one beam indication information, and the beam indication information contained in the candidate indication information indicates beams at the same moment; the second type of beam is a beam belonging to a different set of beams.

As is clear from the foregoing items D-1 to D-3, if there are beams belonging to different sets (i.e., the above-described second type of beams) among the beams indicated by the plurality of beam indication information indicating the beams at the same time, one beam can be selected from the second beams as the beam of the access link. For example, the beam indication information M1 is received in the slot (slot) 1, the beam indication information M2 is received in the slot2, both of which indicate the beam case of the slot10, and the beams indicated by the M1 are the beam a and the beam C; the beams indicated by M2 are beam B, beam D and beam E; if beam a and beam B belong to the same set of beams, beam C and beam D belong to the same set, then beam A, C, E may be the second type of beam, beam B, C, E may be the second type of beam, beam A, D, E may be the second type of beam, and beam B, D, E may be the second type of beam, and one of the following may be used as a beam for the access link:

any of the beams A, C, E;

any of the beams B, C, E;

any of the beams A, D, E;

any of the beams B, D, E;

among the beams A, C, E, B, C, E, A, D, E, or B, D, E, the time indicated by the beam indication information is the closest one to the current time (e.g., M1 and M2, the time of M1 is the closest to the current time, either one of beams a and C may be selected from beams A, C, E, or beam C may be selected from beam B, C, E, or beam a may be selected from beam A, D, E);

One of beams A, C, E, B, C, E, A, D, E, or B, D, E indicated by the highest priority beam indication information (e.g., of M1 and M2, M2 has the highest priority, then beam E may be selected from beam A, C, E, either of beams B and E may be selected from beam B, C, E, or beam E may be selected from beam A, D, E, or either may be selected from beam B, D, E).

In addition, for the foregoing item D-4, in the case where there is UE scheduling of FDM, a plurality of beams may be selected from the foregoing second type of beams as beams of an access link between the relay device and the UE.

Further, for the one or more of the second beams to be adjusted to the beam of the access link according to the preconditions in the D-5 term, for example, it may be: the beams indicated by the beam indication information with the same priority are adopted, otherwise, the beams indicated by the beam indication information with high priority are adopted; alternatively, multiple beams indicated by the same beam indication signaling may be used at the same time, and multiple beams indicated by different beam indication information may not be used at the same time.

I.e. a plurality of beams indicated by the beam indication information of the same priority are adopted, otherwise, a beam indicated by the beam indication information of high priority is adopted, and one or a plurality of beams are selected from the second beams and adjusted to be the beam of the access link;

Alternatively, according to the condition that "a plurality of beams indicated by the same beam indication signaling can be used at the same time and a plurality of beams indicated by different beam indication information cannot be used at the same time", one or more beams are selected from the second beams and adjusted to be beams of the access link.

Optionally, at least one of the following is carried in the beam indication information:

a combination identifier corresponding to the target beam;

a set identifier corresponding to the target beam;

an identification of a panel forming the target beam;

an identification of a port forming the target beam;

the target beam is a beam indicated by the identification of the beam included in the beam indication information.

It is known that the beam indication information may include at least one of the identification information of the beam, and may additionally indicate at least one of the combination identification corresponding to the beam, the corresponding set identification, the identification of the panel forming the beam, and the identification of the port forming the beam.

For example, if the Panel sequence number is indicated in the beam indication information sent to the NCR by the base station, the Panel sequence number indicated in the beam indication information indicates: when the base station configures NCR to do beam training, the base station can instruct the NCR node to do beam training by using one or more beams formed by the designated Panel; when data transmission is performed, the beam formed by the designated one or more Panel is indicated to perform data transmission.

In addition, when a Panel generates a set of beams, the number of the beams in the set of beams is equal to the number of the beams generating the beam, e.g., 4 beams are present for a Panel, then (Panel 1, beam 1) indicates the first beam in the set generated by Panel 1. Thus, when one Panel generates one beam set, a beam can be indicated using (Panel ID, beam index).
