Description

Beam indication method and device and related equipment

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a beam indication method, apparatus, and related devices.

Background

Currently, in a New Radio (NR) system, a downlink channel includes a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical downlink control channel (Physical Downlink Control Channel, PDCCH), an uplink channel includes a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), and a physical uplink control channel (Physical Uplink Control Channel, PUCCH). For high frequency transmission (FR 2 band in NR), due to the limited transmission range, the uplink and downlink channels are typically beamformed and then transmitted to enhance coverage, where the beam direction of the different channels, i.e., the beam indication, needs to be determined by using the beam at the time of signaling the channel transmission.

However, different channels use different beam indication signaling, and each channel performs beam indication independently, so that multiple signaling is required to perform beam indication, which increases complexity and signaling indication overhead of the communication system.

Detailed Description

The term "and/or" in the embodiments of the present disclosure describes an association relationship of association objects, which indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present disclosure means two or more, and other adjectives are similar thereto.

The following description of the embodiments of the present disclosure will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

In the related art, a method of indicating a plurality of channel beams with one beam indication signaling activates a set of TCI states through MAC-CE (signaling of a control element of a MAC layer), and then indicates one of the activated TCI states using DCI (Downlink Control Information ). Two kinds of DCI indications may be employed, one of which is DCI format 1_1 or DCI format1_2 with data scheduling and the other of which is DCI format 1_1 or DCI format1_2 without data scheduling. When the uplink channel and the downlink channel trade with each other, the beam indicated by the beam indication signaling may be used for both the uplink channel and the downlink channel, and is configured to be in a joint TCI mode (joint TCI mode); when MPE (maximum permissible exposure, maximum allowed loss) problem due to object shielding occurs or the terminal device needs to switch the uplink beam, the uplink channel will use a different beam from the downlink channel, so that the beam indication signaling needs to indicate the uplink channel beam and the downlink channel beam, respectively, and is configured as an independent uplink/downlink TCI mode (separate DL/UL TCI mode). But this mechanism of NR Rel-17 only supports single TRP (Transmission Reception Point, transmitting receiving node) transmissions.

For multi-TRP (mTRP) transmissions, in existing protocols, for multi-DCI (M-DCI) -based mTRP transmissions, each CORESET would be configured to associate a coresetpoolndex. Each DCI indicates one TCI state for PDSCH transmission of TRP having the same coresetpoolndex value; for single DCI (S-DCI) -based mTRP transmissions, each DCI indicates two TCI states, one for each PDSCH transmission of two TRPs.

To support the Multi-TRP scenario, it is necessary to indicate the corresponding TCI states/state groups for multiple TRPs. Thus, the number of required TCI states/state groups will increase compared to the srp scenario. There is a need to extend the way beam pointing. On the other hand, for mTRP scenarios, the base station may update only the TCI state/state group of one TRP, or may perform the switching between mTRP and srrp, and in the related art, no related scheme has yet distinguished whether mTRP transmission or srrp transmission needs to be performed through beam indication.

In view of the foregoing, the present disclosure proposes a beam indicating method, apparatus and related devices. The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

The beam indicating method, the beam indicating device and the related devices provided by the disclosure are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a beam pointing method according to an embodiment of the present disclosure. It should be noted that, the beam indicating method in the embodiments of the present disclosure may be performed by a terminal device.

As shown in fig. 1, the beam pointing method may include the steps of:

step 101, receiving a first signaling sent by a network device.

In the embodiment of the disclosure, the terminal device may receive a first signaling sent by the network device, where the first signaling is, for example, DCI signaling, or MAC-CE signaling. It should be noted that, the terminal device according to the embodiments of the present disclosure may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, etc. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like. The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (access terminal), user terminal device (user terminal), user agent (user agent), user equipment (user device), and embodiments of the present disclosure are not limited.

The network device according to the embodiments of the present disclosure may be a base station, which may include a plurality of cells for providing services to terminals. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be operable to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), and the like. In some network structures, the network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

Multiple-input Multiple-output (Multi Input Multi Output, MIMO) transmissions may each be made between a network device and a terminal device using one or more antennas, and the MIMO transmissions may be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

Step 102, in case a first indication field is included in the first signaling, determining at least one TCI state/state group according to the first indication field.

In the embodiment of the disclosure, the first signaling may include one first indication field or include a plurality of second indication fields.

As an example, the first signaling includes a first indication field (e.g., TCI indication field) from which one or more TCI states/state groups may be determined. Wherein each TCI state may be used to characterize a beam and each TCI state set may be used to characterize a beam set.

In case a plurality of second indication fields are included in the first signalling, a TCI state/state group is determined according to each second indication field, step 103.

As another example, a plurality of second indication fields may be included in the first information, each of which may determine a TCI state/state group.

It should be noted that, when the first signaling includes one indication domain, the one indication domain is referred to as a first indication domain; when a plurality of indication fields are included in the first signaling, the plurality of indication fields are referred to as a plurality of second indication fields.

In summary, a first signaling sent by a network device is received; in case a first indication field is included in the first signaling, determining at least one TCI state/state group according to the first indication field; in the case that the first signaling includes a plurality of second indication domains, determining a TCI state/state group according to each second indication domain, thereby, it may be realized that at least one beam/beam group is indicated according to the first indication domain in the first signaling, or it may be realized that a plurality of beams/beam groups are indicated according to the plurality of second indication domains in the first signaling, and beam indication does not need to be performed by adopting a plurality of signaling, so that complexity and signaling indication overhead of the communication system are reduced.

In order to clearly illustrate how at least one TCI state/state group is determined according to the first indication field in the above embodiments, the present disclosure proposes another beam indication method, and it should be noted that the beam indication method of the disclosed embodiments may be performed by a terminal device.

Fig. 2 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 2, the beam pointing method may include the steps of:

step 201, receiving a second signaling sent by the network device.

Wherein the second signaling is used to indicate the correspondence between the activation code points and the TCI state/state groups.

In embodiments of the present disclosure, the network device may send a second signaling to the terminal device, where the second signaling may be used to indicate a correspondence between the activation code points and the TCI state/state groups.

Step 202, receiving a first signaling sent by a network device.

As one possible implementation of the embodiments of the present disclosure, the network device may send a second signaling to the terminal device, where the second signaling may be used to activate the TCI state/state group, and send a first signaling to the terminal device, where the first signaling may be used to indicate that one or more TCI states/state groups are selected from the TCI states/state groups activated in the second signaling. The second signaling may be MAC-CE signaling or RRC (Radio Resource Control ) signaling, where the second signaling may carry two sets of activation code points, and each first activation code point in the first set of activation code points may correspond to a plurality of TCI states/state groups; each of the second set of activate code points may correspond to a TCI state/state set. Further, the second signaling may be one or more.

In step 203, in the case that the first signaling includes a first indication field, at least one TCI state/state group corresponding to an activation code point in the first indication field is determined according to the correspondence indicated by the second signaling.

As an example, the second signaling is one, and in the case that the first signaling includes a first indication field, the first indication field may correspond to an activation code point in the second signaling, and the correspondence of the second signaling indication may be queried according to the activation code point corresponding to the first indication field, so as to determine at least one TCI state/state group corresponding to the activation code point.

For example, according to the activated code point corresponding to the first indication domain, the corresponding relation of the second signaling indication is queried, and then a plurality of TCI states/state groups corresponding to the activated code point can be determined, and further the activated code point corresponding to the first indication domain can be determined to be the first activated code point, and the plurality of TCI states/state groups corresponding to the first activated code point can be used as a plurality of TCI states/state groups corresponding to the activated code point in the first indication domain. For another example, according to the activation code point corresponding to the first indication domain, the corresponding relation of the second signaling indication is queried, and it can be determined that the activation code point corresponds to one TCI state/state group, and further it can be determined that the activation code point in the first indication domain is one of a plurality of second activation code points activated by the second signaling, where one TCI state/state group corresponding to the second activation code point is used as one TCI state/state group corresponding to the activation code point in the first indication domain.

In addition, when the activated code point in the first indication domain is determined to be the first activated code point based on the correspondence of the second signaling indication, when each TCI state/state group corresponding to the first activated code point has an association relationship with the TRP, a plurality of TCI states/state groups associated with the plurality of TRP may be determined according to the plurality of TCI states/state groups corresponding to the first activated code point and the TRP associated with each TCI state/state group.

As another example, the number of second signaling is plural, and there is a correspondence between each second signaling and the first indication domain, and the activation code point in the first indication domain may correspond to at least one TCI state/state group, where the activation code point in the first indication domain is one of the activation code points of the second signaling that has a correspondence with the first indication domain.

It should be noted that, when there are multiple second signaling, when the same TRP is associated between the second signaling and the first indication domain, the corresponding relationship between each second signaling and the first indication domain may be determined, or the first signaling carries associated indication information, where the associated indication information may be used to indicate the second signaling associated with the first indication domain in the first signaling, so as to determine the corresponding relationship between each second signaling and the first indication domain. The association indication information may occupy at least one bit in the first indication field.

As a possible implementation manner of the embodiments of the present disclosure, the first indication domain includes at least two activated code points respectively corresponding to different second signaling, and for any one activated code point of the at least two activated code points, a correspondence indicated by the second signaling corresponding to the one activated code point may be queried to determine at least one TCI state/state group corresponding to the one activated code point.

In summary, by receiving the second signaling sent by the network device, in the case that the first signaling includes a first indication field, at least one TCI state/state group corresponding to an activation code point in the first indication field is determined according to the correspondence indicated by the second signaling, so that the corresponding relationship between the activation code point indicated by the second signaling and the TCI state/state group can be queried according to the activation code point in the first indication field, and at least one TCI state/state group can be effectively determined.

In order to clearly illustrate how to determine a TCI state/state group according to each second indication field in the above embodiments, the present disclosure proposes another beam indication method, and it should be noted that the beam indication method of the disclosed embodiments may be performed by a terminal device.

Fig. 3 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 3, the beam pointing method may include the steps of:

step 301, receiving a second signaling sent by a network device.

The second signaling is used to indicate the correspondence between the activation code points and the TCI states/state groups.

Step 302, a first signaling sent by a network device is received.

In step 303, in the case that the first signaling includes a plurality of second indication domains, a TCI state/TCI state group corresponding to the activated code point in each second indication domain is determined according to the correspondence of the second signaling.

As an example, the second signaling is one, the first signaling includes a plurality of second indication domains, each second indication domain may correspond to an activation code point in the second signaling, according to the activation code point, the correspondence indicated by the second signaling is queried, it may be determined that the activation code point corresponds to at least one TCI state/state group, and in the case that the activation code point corresponds to a plurality of TCI states/state groups, an effective TCI state/state group may be determined from a plurality of TCI states/state groups. For example, according to the activated code point in the second indication domain, the corresponding relation of the second signaling indication is queried, the activated code point in the second indication domain is determined to be a first activated code point, the first activated code point corresponds to a plurality of TCI states/state groups, and an effective TCI state/state group is determined from the plurality of TCI states/state groups to be used as a TCI state/TCI state group corresponding to the activated code point in the second indication domain. Wherein the TCI state/state group in effect may be one of the following: the TCI states/state groups corresponding to the first activated code points are consistent with the TCI states/state groups of the set ordering positions; or, the TCI state/state group of the same TRP is associated with the second indicator field in the plurality of TCI states/state groups corresponding to the first activated code point.

For another example, according to the activated code point in the second indication domain, the corresponding relation of the second signaling indication is queried, and it is determined that the activated code point in the second indication domain is the second activated code point, where the second activated code point corresponds to one TCI state/state group and may be used as one TCI state/state group corresponding to the activated code point in the second indication domain.

As another example, the second signaling is plural, the first signaling includes plural second indication domains, and a correspondence exists between each second signaling and the second indication domain. The active code point in the second indication domain is one of the active code points of the second signaling having a corresponding relation with the second indication domain, at least one TCI state/state group corresponding to the active code point in each second indication domain is determined according to the corresponding relation indicated by the second signaling, and one valid TCI state/state group can be determined from the plurality of TCI states/state groups when the active code point corresponds to the plurality of TCI states/state groups.

When the number of the second signaling is plural and the same TRP is associated between the second signaling and the second indication domain, the corresponding relationship between each second signaling and the second indication domain may be determined, or the first signaling carries association indication information, where the association indication information is used to indicate the second signaling associated with the second indication domain in the first signaling, so as to determine the corresponding relationship between each second signaling and the second indication domain, and the association indication information may occupy at least one bit in the second indication domain.

It should be noted that the execution of steps 301 to 302 may be implemented in any manner in each embodiment of the disclosure, which is not limited to this embodiment, and is not repeated herein.

In summary, the second signaling sent by the network device is received; in the case that the first signaling includes a plurality of second indication domains, determining a TCI state/state group corresponding to an activation code point in each second indication domain according to a correspondence of second signaling indications, thereby, querying the correspondence of the second signaling indications according to the activation code point in each second indication domain can be implemented, and determining a TCI state/TCI state group corresponding to the activation code point in each second indication domain effectively.

In order to clearly illustrate how the above embodiments determine at least one TCI state/state group corresponding to an activation code point in a first indication domain according to the correspondence relationship of the second signaling indication, the present disclosure proposes another beam indication method, and it should be noted that, the beam indication method of the disclosed embodiments may be performed by a terminal device.

Fig. 4 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 4, the beam pointing method may include the steps of:

step 401, receiving a second signaling sent by the network device.

Step 402, a first signaling sent by a network device is received.

Step 403, in the case that the first signaling includes a first indication field and the activation code point in the first indication field is determined to be the first activation code point based on the correspondence indicated by the second signaling, determining the TCI states/state groups of the plurality of TRPs according to the plurality of TCI states/state groups corresponding to the first activation code point and the TRPs associated with each TCI state/state group.

As an example, according to the activated code point corresponding to the first indication domain, the correspondence of the second signaling indication is queried to determine at least one TCI state/state group corresponding to the activated code point corresponding to the first indication domain, when the activated code point corresponding to the first indication domain corresponds to a plurality of TCI states/state groups, the activated code point in the first indication domain may be determined to be the first activated code point, the TCI state/state group corresponding to the first activated code point is a plurality of TCI states/state groups, and each TCI state/state group in the plurality of TCI states/state groups corresponding to the first activated code point has an associated TRP, that is, an association relationship between the TCI state/state group and the TRP is determined, so that in the present disclosure, the TCI state/state group associated with the plurality of TRPs may be queried according to the association relationship.

It should be noted that the execution of steps 401 to 402 may be implemented in any manner in each embodiment of the disclosure, which is not limited to this embodiment, and is not repeated herein.

In summary, when the activated code point in the first indication domain is determined to be the first activated code point based on the correspondence indicated by the second signaling, the TCI state/state group of the plurality of TRPs is determined according to the plurality of TCI states/state groups corresponding to the first activated code point and the TRP associated with each TCI state/state group, so that the TCI state/state group of the plurality of TRPs can be effectively determined according to the plurality of TCI states/state groups corresponding to the activated code point in the first indication domain and the TRP associated with each TCI state/state group.

In order to clearly illustrate how the above embodiments determine one TCI state/TCI state group corresponding to an activation code point in each second indication domain according to the correspondence relationship of the second signaling indication, the present disclosure proposes another beam indication method, and it should be noted that, the beam indication method of the disclosed embodiments may be performed by the terminal device.

Fig. 5 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 5, the beam pointing method may include the steps of:

step 501, receiving a second signaling sent by a network device.

Step 502, a first signaling sent by a network device is received.

In step 503, when the first signaling includes a plurality of second indication fields, and it is determined that the activation code point indicated by at least one second indication field is the first activation code point based on the correspondence indicated by the second signaling, an effective TCI state/state group is determined from a plurality of TCI states/state groups corresponding to the first activation code point.

As an example, the corresponding relation of the second signaling indication is queried by the activation code point corresponding to each second indication domain, at least one TCI state/state group corresponding to the activation code point corresponding to each second indication domain may be determined, when the activation code point corresponding to the second indication domain corresponds to a plurality of TCI states/state groups, the activation code point corresponding to the second indication domain may be determined to be a first activation code point, when the activation code point corresponding to the second indication domain corresponds to one TCI state/state group, the activation code point corresponding to the second indication domain may be determined to be a second activation code point, and further, when the activation code point indicated by at least one second indication domain is a first activation code point, one valid TCI state/state group may be determined from a plurality of TCI states/state groups corresponding to the first activation code point.

It should be noted that, the effective TCI state/state group may be one of the following: the TCI states/state groups corresponding to the first activated code points are consistent with the TCI states/state groups of the set ordering positions; or, the TCI state/state group of the same TRP is associated with the second indicator field in the plurality of TCI states/state groups corresponding to the first activated code point.

Step 504, determining the TCI state/state group of the TRP associated with the at least one second indication field based on the validated TCI state/state group.

As an example, the second indication domain corresponding to the effective TCI state/state group may be determined according to the effective TCI state/state group, and since each second indication domain has an association relationship with the TRP, and further, the TRP associated with the second indication domain corresponding to the effective TCI state/state group has an association relationship with the effective TCI state/state group, in the present disclosure, the TCI state/state group associated with the TRP associated with at least one second indication domain may be determined according to the above association relationship is queried according to the TRP associated with the second indication domain corresponding to the effective TCI state/state group.

It should be noted that the execution of steps 501 to 502 may be implemented in any manner of embodiments of the disclosure, which are not limited to this and are not repeated herein.

In summary, by determining, based on the correspondence indicated by the second signaling, that the activation code point indicated by the at least one second indication field is the first activation code point, determining an effective TCI state/state group from a plurality of TCI states/state groups corresponding to the first activation code point, and determining a TCI state/state group of the TRP associated with the at least one second indication field according to the effective TCI state/state group, when the activation code point indicated by the at least one second indication field is the first activation code point, it is possible to effectively determine the TCI state/state group of the TRP associated with the at least one second indication field according to one effective TCI state/state group of the plurality of TCI states/state groups corresponding to the first activation code point.

Fig. 6 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 6, the beam pointing method may include the steps of:

Step 601, receiving a second signaling sent by the network device.

Step 602, a first signaling sent by a network device is received.

In step 603, when the first signaling includes a plurality of second indication fields, and it is determined that the activation code point indicated by at least one second indication field is the first activation code point based on the correspondence indicated by the second signaling, an effective TCI state/state group is determined from a plurality of TCI states/state groups corresponding to the first activation code point.

As an example, the corresponding relation of the second signaling indication is queried by the activation code point corresponding to each second indication domain, at least one TCI state/state group corresponding to the activation code point corresponding to the second indication domain may be determined, when the activation code point corresponding to the second indication domain corresponds to a plurality of TCI states/state groups, the activation code point corresponding to the second indication domain may be determined to be a first activation code point, when the activation code point corresponding to the second indication domain corresponds to one TCI state/state group, the activation code point corresponding to the second indication domain may be determined to be a second activation code point, and further, when the activation code point indicated by at least one second indication domain is a first activation code point, one valid TCI state/state group may be determined from a plurality of TCI states/state groups corresponding to the first activation code point.

Step 604, determining the TCI state/state group of the TRP associated with the effective TCI state/state group according to the effective TCI state/state group.

As an example, each TCI state/state group corresponding to the first activation code point has an associated TRP, the valid TCI state/state group has an associated TRP, and the TCI state/state group associated with the TRP associated with the valid TCI state/state group may be determined according to an association relationship between the TRP associated with the valid TCI state/state group and the valid TCI state/state group.

It should be noted that the execution of steps 601 to 602 may be implemented in any manner of embodiments of the present disclosure, which are not limited to this and are not repeated.

In summary, under the condition that the activated code point indicated by at least one second indication domain is determined to be the first activated code point based on the corresponding relation of the second signaling indication, determining an effective TCI state/state group from a plurality of TCI states/state groups corresponding to the first activated code point; and determining the TCI state/state group of the TRP associated with the effective TCI state/state group according to the effective TCI state/state group, thereby realizing that when the activation code point indicated by at least one second indication domain is the first activation code point, the TCI state/state group of the TRP associated with the effective TCI state/state group is effectively determined according to one effective TCI state/state group of a plurality of TCI state/state groups corresponding to the first activation code point.

In order to clearly illustrate how the above embodiments determine one TCI state/state group corresponding to an active code point in each second indication domain from the TCI states/state groups corresponding to the active code points indicated by the second signaling, the present disclosure proposes another beam indication method, and it should be noted that the beam indication method of the disclosed embodiments may be performed by the terminal device.

Fig. 7 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 7, the beam pointing method may include the steps of:

step 701, receiving a second signaling sent by a network device.

Step 702, a first signaling sent by a network device is received.

As an example, the activated code point indicated in the second signaling includes a second activated code point, where the TCI state/state group corresponding to the second activated code point is one.

In step 703, when the first signaling includes a plurality of second indication domains and the activation code point indicated by at least one second indication domain is determined to be the second activation code point based on the correspondence indicated by the second signaling, the TCI state/state group of the TRP associated with the at least one second indication domain is determined according to the TCI state/state group corresponding to the second activation code point.

As an example, each second indication domain has an association relationship with TRP, the corresponding relation of the second signaling indication is queried for the activation code point corresponding to each second indication domain, so as to determine that the activation code point corresponding to each second indication domain is the first activation code point or the second activation code point, and when the activation code point indicated by at least one second indication domain is the second activation code point, each second activation code point corresponds to one TCI state/state group, according to one TCI state/state group corresponding to the second activation code point, the second indication domain corresponding to the one TCI state/state group can be determined, and since each second indication domain has an association relationship with TRP, further, the TRP associated with the second indication domain corresponding to the one TCI state/state group can be determined, so that in the present disclosure, the second indication domain corresponding to the one TCI state/state group can be determined according to the query related relation associated with the second indication domain corresponding to the one TCI state/state group.

As another example, each second indication domain has an association relationship with TRP, and the corresponding activated code point of each second indication domain is queried for the corresponding relationship of the second signaling indication, so as to determine that the activated code point corresponding to each second indication domain is the first activated code point or the second activated code point, and when the activated code points indicated by each second indication domain are all the second activated code points, each second activated code point corresponds to one TCI state/state group, and the second activated code point corresponds to one TCI state/state group and the TRP associated with the corresponding second indication domain has an association relationship between TRP associated with the corresponding second indication domain, so that in the present disclosure, the TCI state/state group of the TRP associated with the second indication domain corresponding to the one TCI state/state group can be determined according to the above-mentioned association relationship queried for the TRP associated with the corresponding second indication domain.

It should be noted that, the execution process of step 701 may be implemented in any manner of each embodiment of the disclosure, which is not limited to this embodiment, and is not repeated herein.

In summary, when the activated code point indicated by the at least one second indication domain is determined to be the second activated code point based on the correspondence indicated by the second signaling, the TCI state/state group of the TRP associated with the at least one second indication domain is determined according to the TCI state/state group corresponding to the second activated code point, thereby effectively determining the TCI state/state group of the TRP associated with the at least one second indication domain according to the TCI state/state group corresponding to the second activated code point indicated by the at least one second indication domain.

It should be appreciated that in the embodiments of the present disclosure, according to the first signaling and the second signaling, the terminal device may also be switched from multiple TRP to single TRP, and for this reason, another beam indication method is proposed in the present disclosure.

Fig. 8 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 8, the beam pointing method may include the steps of:

step 801, receiving a second signaling and a first signaling sent by a network device.

Step 802, switching the terminal device from multiple TRPs to single TRPs according to the first signaling and the second signaling.

As an example, the second signaling indicates that the activated code point includes a second activated code point, where the TCI state/state group corresponding to the second activated code point is one.

As a possible implementation manner of the embodiments of the present disclosure, in a case where the first signaling includes a first indication field and the activation code point in the first indication field is determined to be a second activation code point based on the correspondence of the second signaling indication, the terminal device is switched from multiple TRP to single TRP based on first switching information associated with the second activation code point.

As another possible implementation manner of the embodiments of the present disclosure, in a case where the first signaling includes a first indication field and the activation code point in the first indication field is determined to be a second activation code point based on the correspondence indicated by the second signaling, the terminal device is switched from multiple TRP to single TRP based on second switching information carried in the first signaling.

In addition, when the first signaling includes a plurality of second indication domains and it is determined that second activation code points in the plurality of second indication domains meet a set condition based on a correspondence relation of the second signaling, the terminal device is switched from multiple to single TRP based on a switching policy corresponding to the set condition.

In summary, the terminal device is switched from multiple TRP to single TRP according to the first signaling and the second signaling by receiving the first signaling and the second signaling sent by the network device, thereby, the terminal device can be switched from multiple TRP to single TRP according to the first signaling and the second signaling.

It should be appreciated that, in the embodiment of the present disclosure, according to the first signaling and the second signaling, a TCI state/state group of one TRP set in the plurality of TRPs employed by the terminal device may also be implemented, and for this reason, another beam indication method is proposed in the present disclosure.

Fig. 9 is a flowchart of another beam pointing method according to an embodiment of the present disclosure.

As shown in fig. 9, the beam pointing method may include the steps of:

step 901, receiving a second signaling and a first signaling sent by a network device.

Step 902, updating a TCI state/state group of one TRP set in the plurality of TRPs employed by the terminal device according to the first signaling and the second signaling.

As a possible implementation manner of the embodiments of the present disclosure, when the first signaling includes a first indication field and the active code point in the first indication field is determined to be a second active code point based on the correspondence indicated by the second signaling, the TCI state/state group of one TRP set in the plurality of TRPs adopted by the terminal device is updated according to the TCI state/state group corresponding to the second active code point.

As another possible implementation manner of the embodiments of the present disclosure, in a case where the first signaling includes a first indication field and the activation code point in the first indication field is determined to be the second activation code point based on the correspondence indicated by the second signaling, the TCI state/state group of one TRP of the plurality of TRPs employed by the terminal device is updated based on the first update information associated with the second activation code point.

In addition, when the first signaling includes a plurality of second indication domains and it is determined that the second activation code points in the plurality of second indication domains meet the setting conditions based on the correspondence of the second signaling, the TCI state/state group of one TRP of the plurality of TRPs adopted by the terminal device is updated based on the update policy corresponding to the setting conditions.

In summary, by receiving the first signaling and the second signaling sent by the network device, the TCI state/state group of one TRP set in the plurality of TRPs employed by the terminal device is updated according to the first signaling and the second signaling, thereby updating the TCI state/state group of one TRP set in the plurality of TRPs employed by the terminal device according to the first signaling and the second signaling.

In order to more clearly illustrate the above embodiments, an example will now be described.

For example, taking a multi-TRP composed of two TRPs, taking a DCI supporting two formats as an example for TCI status indication, one of them is DCI format 1_1/1_2 with data scheduling. The DCI includes a TCI field for indicating TCI status/status groups of single or multiple TRPs; another is DCI format 1_1/1_2 without data scheduling. The DCI includes two TCI fields, each field indicating a TCI state/state group of one TRP.

For example, using one MAC-CE signaling (second signaling) to activate TCI states/state groups, as shown in table 1, assume that each MAC-CE activates N code points (activated code points), where the first N/2 code points, each code point is associated with one or more TCI states/state groups; the last N/2 code points are associated with one TCI state/state group.

Table 1 MAC-CE signaling

Code point	TCI state/state group
		P1	{TCI_1},{TCI_5}
P2	{TCI_4},{TCI_11}
		P3	{TCI_7},{TCI_9}
P4	{TCI_10},{TCI_17}
		P5	{TCI_2}
P6	{TCI_3}
		P7	{TCI_6}
P8	{TCI_8}

Both DCIs select a code point from the TCI state/state group activated in the MAC-CE signaling to perform TCI state indication. Each bracket in table 1 represents a TCI state/state group. If the joint TCI mode is used, the same TCI state is used for each TRP uplink and downlink, so only one TCI state needs to be indicated. If an independent uplink and downlink mode is used, each TRP uplink and downlink uses a different TCI state, thus requiring two TCI states to be indicated, i.e., a TCI state group. In this embodiment, it is assumed that the joint TCI mode is used, so that only one TCI state is included in each bracket.

It should be noted that, the following correspondence is predefined by the communication system: assume that the MAC-CE activates N code points, the first N/2 of which correspond to code points of the TCI field in DCI format 1_1/1_2 of the data schedule; the latter N/2 code points correspond to the code points of each TCI field in DCI format 1_1/1_2 without data scheduling.

Taking the above MAC-CE signaling as an example, n=8, when the indication is made using DCI format 1_1/1_2 with data scheduling, there is only one TCI field. The code point value in the TCI field corresponds to P1-P4 of the MAC-CE code point. Assuming that the code point in the TCI field corresponds to P2, the base station indicates to the terminal device tci_4 and tci_11, which are used for transmission of two TRP, respectively. When the DCI format 1_1/1_2 without data scheduling is used for indication, two TCI domains are included, and the code point value of each TCI domain corresponds to P5-P8 of the MAC-CE code point. Let the code point in the first TCI domain correspond to P6 and the code point in the second TCI domain corresponds to P8. The base station indicates tci_3 and tci_8 to the terminal, which are used for transmission of two TRP, respectively.

For example, a multi-TRP consisting of two TRPs is used to support the TCI status indication of two formats of DCI, one of which is DCI format 1_1/1_2 with data scheduling. The DCI includes a TCI field for indicating TCI status/status groups of single or multiple TRPs; another is DCI format 1_1/1_2 without data scheduling. The DCI includes two TCI fields, each field indicating a TCI state/state group of one TRP.

For example, a TCI state/state group is activated using a MAC-CE signaling as shown in Table 2. Both DCIs described above select a code point from the TCI state/state group activated in this signaling for TCI state indication. Each bracket in table 2 represents a TCI state/state group.

Table 2 MAC-CE signaling

It should be noted that, the following correspondence is predefined by the communication system: the DCI formats 1_1/1_2 with data scheduling and the DCI formats 1_1/1_2 without data scheduling correspond to all code points in the MAC-CE activation signaling. When two TCI states/state groups are associated with a code point corresponding to one TCI field in DCI format 1_1/1_2 without data scheduling, only one of the TCI states/state groups is validated.

When the DCI format 1_1/1_2 with data scheduling is used for indication, there is only one TCI field. Assuming that the code point in this TCI domain corresponds to P2, the base station indicates tci_4 and tci_11 to the terminal, which are used for transmission of two TRP, respectively. When indicated using DCI format 1_1/1_2 without data scheduling, two TCI fields are included therein. Assuming that the code point in the first TCI domain corresponds to P6, it associates two TCI states tci_7 and tci_9; the code point in the second TCI field corresponds to P8, which associates two TCI states tci_10 and tci_17. One way is that the communication system predefines that only the first TCI state (tci_7) in the first TCI domain is active and that only the second TCI state (tci_17) in the second TCI domain is active. The base station indicates to the terminal device tci_7 and tci_17, which are used for transmission of two TRP, respectively. Alternatively, the communication system predefines the TCI state in effect for each TCI domain as the TCI state associated with the same TRP as that TCI domain.

For another example, a multi-TRP consisting of two TRPs is used to support the TCI status indication of DCI in two formats. One of them is DCI format 1_1/1_2 with data scheduling. The DCI includes a TCI field for indicating TCI states/state groups of single or multiple TRPs. Another is DCI format 1_1/1_2 without data scheduling. The DCI includes two TCI fields, each field indicating a TCI state/state group of one TRP.

For example, two MAC-CE signaling is used to activate TCI states/state groups. Wherein each MAC-CE signaling is associated with DCI of one format. For example, the first MAC-CE signaling is associated with DCI formats 1_1/1_2 with data scheduling, and each code point in the first MAC-CE signaling may correspond to one or more TCI states/state groups. The code points in DCI format 1_1/1_2 with data scheduling correspond to the code points in the first MAC-CE signaling. The second MAC-CE signaling is associated with DCI formats 1_1/1_2 without data scheduling, and each code point in the second MAC-CE signaling may correspond to only one TCI state/state group. The code point of each TCI field in DCI format 1_1/1_2 without data scheduling corresponds to the code point in the second MAC-CE signaling. It should be noted that, the MAC-CE signaling includes an indication of the first MAC-CE or the second MAC-CE information, so that the terminal device may determine the TCI state/state group according to the above correspondence.

For example, taking a multi-TRP consisting of two TRPs, a DCI supporting two formats is used for TCI status indication, wherein one of the two formats is DCI format 1_1/1_2 with data scheduling, and the DCI includes a TCI field for indicating TCI status/status groups of single or multiple TRPs; another is DCI format 1_1/1_2 without data scheduling. The DCI includes two TCI fields, each field indicating a TCI state/state group of one TRP.

For example, two MAC-CE signaling is employed to activate a TCI state/state group, where each MAC-CE signaling is associated with one TRP. In one embodiment, the code point of each MAC-CE signaling may correspond to only one TCI state/state group. For example, a first MAC-CE signaling is associated with a first TRP and a second MAC-CE signaling is associated with a second TRP. The code point of each TCI field in DCI format 1_1/1_2 without data scheduling corresponds to the code point in one MAC-CE signaling. It may be that the TCI field and MAC-CE signaling associated with the same TRP correspond. For the TCI field in DCI format 1_1/1_2 with data scheduling, as shown in table 3, the bits (bits) of the field are divided into two parts, each corresponding to a code point in MAC-CE signaling.

Table 3 TCI field in DCI format 1_1/1_2 with data scheduling

0111

The bit sequence "0111" may be split into two parts, where the first two bits "01" are the first part, corresponding to the code point in one MAC-CE signaling, and the second two bits "11" are the second part, corresponding to the code point in the other MAC-CE signaling.

For another example, a multi-TRP consisting of two TRPs is used to support the TCI status indication of DCI in two formats. One is DCI format 1_1/1_2 with data scheduling, where the DCI includes a TCI field for indicating TCI states/state groups of single or multiple TRPs; another is DCI format 1_1/1_2 without data scheduling. The DCI includes two TCI fields, each field indicating a TCI state/state group of one TRP.

For example, two MAC-CE signaling is used to activate TCI states/state groups. Assuming that each MAC-CE activates N code points, the first N/2 code points corresponding to the TCI domain in DCI format 1_1/1_2 of the data schedule, each code point being associated with one or more TCI states/state groups; the latter N/2 code points correspond to the code points of each TCI field in DCI format 1_1/1_2 without data scheduling, each code point being associated with one TCI state/state group.

For the TCI field in DCI format 1_1/1_2 with data scheduling, the bits of this field are split into two parts. The first part is used to select one of two MAC-CE signaling and the second part is used to determine the first N/2 code points in this MAC-CE signaling, indicating one or more TCI states/state groups. For each TCI field in DCI format 1_1/1_2 without data scheduling, it corresponds to the last N/2 code points in one MAC-CE signaling. The manner in which a specific TCI field is associated with one of the two MAC-CE signaling is described in the above embodiments, and is not described in detail.

Also for example, for the above example, when a code point of a MAC-CE corresponds to one TCI state/state group, it may indicate that multiple TRPs are switched to a single TRP, or that only one of the TCI states of the TRP is updated in a multi TRP scenario. The above MAC-CE signaling may be added with indication information for each code point to distinguish between TCI update or srrp/mTRP switching. One way is to add a new domain, as shown in table 4,

table 4 MAC-CE activation signaling

Code point	TCI update or sTRP/mTRP handover	TCI state/state group
			P1		{TCI_1},{TCI_5}
P2		{TCI_4},{TCI_11}
			P3	00	{TCI_3}
P4	00	{TCI_8}
			P5	10	{TCI_2}
P6		{TCI_7},{TCI_9}
			P7	01	{TCI_6}
P8		{TCI_10},{TCI_17}

It should be noted that the system predefines the meaning of the bit information in this domain. Where "00" indicates an sTRP/mTRP switch, "01" indicates a TCI state/state group updating a first TRP, and "10" indicates a TCI state/state group updating a second TRP.

Another implementation way is to increase the indication information by expanding the bit number of the original indication domain without adding a new indication domain. For example, the spreading code point field (Pi, i=1, 2, …, 8) or other existing information fields.

Another implementation is to indicate in DCI format 1_1/1_2 to switch the multi-TRP to a single TRP or to update the TCI state of only one of the TRPs in a multi-TRP scenario. For example, as shown in Table 5, one DCI field is added,

Table 5 new indication field in DCI

Bits
	00
01
	10
Null

In another way, in DCI having two TCI fields, the indication field may not be added, and the judgment may be performed according to the bit value of each TCI field. For example, when the values of the two TCI fields are different and are valid, mTRP transmission is indicated; when the values of the two TCI domains are the same and are valid values, the sTRP transmission is represented; when one TCI field value is invalid and the other TCI field value is valid, one TCI state is updated.

In the above examples, the multi-TRP consisting of two TRPs was taken as an example. The present disclosure can also be used for multi-TRP consisting of more than two TRPs. In this case, more than two TCI fields may be included in the DCI. One code point in the MAC-CE may correspond to more than two TCI states/state groups. The rest of the modes are the same, and the disclosure is not repeated.

According to the beam indication method, first signaling sent by network equipment is received; in case a first indication field is included in the first signaling, determining at least one TCI state/state group according to the first indication field; in the case that the first signaling includes a plurality of second indication domains, determining a TCI state/state group according to each second indication domain, thereby, it may be realized that at least one beam/beam group is indicated according to the first indication domain in the first signaling, or it may be realized that a plurality of beams/beam groups are indicated according to the plurality of second indication domains in the first signaling, and beam indication does not need to be performed by adopting a plurality of signaling, so that complexity and signaling indication overhead of the communication system are reduced.
