[0203] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the rest or all of the protocol layers are distributed in the DU and controlled by the CU, but not limited thereto.

[0204] In some embodiments, the core network device can be one device including one or more network elements, or can be multiple devices or device groups including all or part of the one or more network elements. The network element can be virtual or physical. The core network includes at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next-generation core (NGC).

Those skilled in the art can know that the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems as the system architecture evolves and new business scenarios appear.

[0206] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1A or part of the subject, but are not limited thereto. The subjects shown in FIG. 1A are examples, and the communication system can include all or part of the subjects in FIG. 1A, or include other subjects other than those in FIG. 1A.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0208] In the field of communication technology, communication devices such as satellites in a non-terrestrial network (NTN) or access network devices in a terrestrial network (TN) have payload power limitations and may not be able to make all their beams meet the "nominal" effective isotropic radiated power (EIRP).

[0209] Taking an NTN network as an example, different beam coverage areas (beam footprints) under one satellite belong to different cells, that is, each beam covers a specific area; or, different beam coverage areas under one satellite belong to the same cell. That is, the beam coverage areas (beam footprints) under one satellite can be one-to-one or many-to-one with the cells.

[0210] To achieve DL coverage enhancement of a communication device, the present disclosure proposes that when multiple beam coverage areas under one communication device belong to one cell, the communication device can dynamically turn on or off some beams to achieve dynamic allocation of inter-beam power, thereby ensuring that the turned-on beams can all meet the EIRP requirement. That is, a discontinuous transmission (DTX) and / or discontinuous reception (DRX) management mechanism is adopted for the beams under the communication device. This provides conditions for maximizing the number of simultaneously activated beams, maximizing the number of simultaneously served terminals, and improving the throughput of the communication device, thereby achieving DL coverage enhancement of the communication device.

[0281] In some embodiments, the step S2105 can be performed before the step S2104, or can also be performed simultaneously with the step S2104, and the present disclosure does not make any limitation in this regard.

Therefore, not only the function of the terminal is reduced, but also the dynamic opening or closing of some beams is realized, the dynamic allocation of power among beams is realized, it is ensured that the opened beams can meet the EIRP requirement, and the conditions for maximizing the number of simultaneously activated beams, maximizing the number of simultaneously served terminals, and improving the throughput of the communication system are provided.

[0295] In some embodiments, if there is an activated beam of a CORESET on the currently activated BWP of the terminal 101 that is not activated beam DTX, the terminal 101 can monitor the PDCCH of the serving cell where the activated BWP is located.

[0296] In some embodiments, if all activated beams of the CORESET on the currently activated BWP of the terminal 101 are activated beam DTX, but at least one beam is currently in the beam DTX active period, the terminal 101 can also monitor the PDCCH.

[0528] FIG. 5 is an interaction diagram of a beam control method according to an embodiment of the present disclosure. As shown in FIG. 5, the embodiment of the present disclosure relates to a beam control method for a terminal 101 and a network device 102, and the above method comprises:

[0529] Step S5101, the network device 102 sends first information to the terminal 101.

[0530] Step S5102, the network device 102 transmits with the terminal 101 based on the first beam configuration.

[0531] For detailed descriptions of steps S5101 to S5102, refer to the descriptions of the above embodiments.

[0532] The following is an exemplary description of the above method.

[0533] The terminal receives the Beam DTX and / or DRX configuration issued by the network device, and activates the Beam DTX and / or DRX according to the indication of the network device.

[0534] Optionally, the Beam DTX and / or DRX configuration includes one or more of the following:

[0535] Beam ID corresponding to the DTX / DRX;

[0536] Periodicity of the DTX / DRX;

[0537] Starting time offset of the DTX / DRX;

[0538] On duration length of the DTX / DRX;

[0539] Type of the DTX / DRX, i.e. DTX only, DTX+DRX, or DRX only.

[0540] For example, the Beam DTX and / or DRX configuration can be included in tci-StatesToAddModList or dl-OrJointTCI-StateList. Specifically, it can be configured separately for each TCI state in the list. Each TCI state can provide one or more periodicity / starting time offset / on duration configurations. Alternatively, a common list of periodicity / starting time offset / on duration configurations is provided, and each TCI state can specify the Index in the common configuration list to determine the specific one or more periodicity / starting time offset / on duration configurations.

[0541] Optionally, the network device can indicate the activation or deactivation of the Beam DTX / DRX via DCI or MAC CE or RRC, and provide the Beam ID information in the indication. The network device can indicate the periodicity / starting time offset / on duration configuration when activating the Beam DTX / DRX, such as indicating the configuration Index, or providing the specific configuration value. It can also only indicate one or more of the periodicity / starting time offset / on duration configuration, and the others are configured by RRC. When DCI is used to indicate the activation of the Beam DTX / DRX, the PDCCH is addressed by the Group RNTI configured for the Beam DTX / DRX. The network device can indicate one or more Beams in the activation / deactivation indication.

[0542] Optionally, the Beam ID can be a TCI state, or an SRS Resource ID and / or an SRS Resource Set ID.

[0543] Optionally, the activation / deactivation indication can distinguish between Beam DTX and Beam DRX, respectively.

[0544] Optionally, if a Beam DTX / DRX is configured and activated for a Beam, the UE starts a DTX / DRX ondurationTimer for the Beam periodically according to the configured period, the starting time offset, and the onduration.

[0545] Optionally, the UE starts a DTX / DRX ondurationTimer for a Beam according to the configured period, the starting time offset, and the onduration regardless of whether the Beam is currently activated.

[0546] For example, the UE starts a DTX / DRX ondurationTimer for a Beam according to the configured period, the starting time offset, and the onduration only if the Beam is activated.

[0547] For example, the UE starts a DTX / DRX ondurationTimer for a Beam according to the configured period, the starting time offset, and the onduration only if the Beam is activated and used.

[0548] For example, if a Beam DTX is activated for the beam corresponding to the PDCCH of the UE, the UE does not monitor the PDCCH during the Beam DTX inactive period of the PDCCH beam.

[0549] For example, if a Beam DTX is activated for all the activated beams of all the CORESETs on the currently activated BWP of the UE, the UE does not monitor the PDCCH during the Beam DTX inactive period. For multiple beams scenario, the Beam DTX inactive period is the period during which all the beams are in DTX inactive period. The PDCCH is for the serving cell where the activated BWP is located. In this case, the reception of PDSCH of SPS is not affected.

[0550] Optionally, if a Beam DTX is not activated for the beam corresponding to the PDCCH of the UE, or although a Beam DTX is activated, the beam is in DTX active period, the UE performs at least one of the following:

[0551] Monitors the PDCCH.

[0552] If ra-ContentionResolutionTimer or msgB-ResponseWindow is running, monitor PDCCH

[0553] If SR is sent on PUCCH and is pending, monitor PDCCH

[0554] If ra-ResponseWindow of SpCell is running, monitor PDCCH

[0555] If CFRA has successfully received RAR but has not received new transmission scheduling, monitor PDCCH

[0556] For example, if there is one CORESET whose activated Beam is not activated Beam DTX on the UE's current active BWP, the UE monitors PDCCH. The PDCCH is for the serving cell where the active BWP is located.

[0557] For example, if all CORESETs whose activated Beams are activated Beam DTX on the UE's current active BWP, but at least one Beam is currently in Beam DTX active period, the UE monitors PDCCH.

[0558] Optionally, if one or more SPS (Semi-Persistent Scheduling) configured by the UE are activated, and their corresponding beams are activated Beam DTX and are in DTX inactive period, the UE performs at least one of the following for each of the one or more SPS, respectively:

[0559] The MAC layer does not instruct the physical layer to receive Transport Blocks of the SPS corresponding DL-SCH.

[0560] The MAC layer does not indicate the existence of SPS, nor does it provide stored HARQ information to the HARQ entity.

[0561] The MAC layer does not set the HARQ process ID associated with the PDSCH corresponding to the SPS.

[0562] The MAC layer does not consider the NDI bit flip of the HARQ process associated with the PDSCH corresponding to the SPS.

[0563] Optionally, if the Beam DRX of the Beam corresponding to the PUCCH of the UE is activated and the UE is in the Beam DRX inactive period, the UE performs at least one of the following:

[0564] Does not indicate the physical layer to transmit SR on the PUCCH;

[0565] Does not increment the SR_COUNTER for the SR;

[0566] Does not start the sr-ProhibitTimer for the SR;

[0567] Does not report periodic CSI on the PUCCH.

[0568] Optionally, if the UE is configured with one or more Configured Grants and the Beam DRX of the Beam corresponding to the Configured Grant is activated and the UE is in the Beam DRX inactive period, the UE performs at least one of the following for each Configured Grant respectively:

[0569] Does not transmit the Configured Grant and the corresponding HARQ information to the HARQ entity;

[0570] Does not indicate the HARQ process associated with the Configured Grant to trigger a new transmission or retransmission;

[0571] Does not transmit semi-persistent CSI on the PUSCH.

[0572] Optionally, if the UE triggers emergency service, if the UE does not have available uplink resources to transmit uplink data, and the Beam DRX of the Beam corresponding to the PUCCH of the UE is activated and in the inactive period, the UE triggers random access.

[0573] Optionally, if the UE triggers emergency service, if the UE has available uplink resources to transmit uplink data, but the Beam DRX of the beam corresponding to the PUSCH of the uplink resource is activated and in the inactive period, the UE triggers random access.

[0574] Optionally, the terminal reports network capability information to indicate whether the network supports Beam DTX / DRX.

[0575] Optionally, Beam DTX and Beam DRX can be indicated respectively.
