Referring to fig. 2, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 2, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of UEs 11 and a number of access network devices 12 and/or at least one core network device 13.

Wherein UE 11 may be a device that provides voice and/or data connectivity to a user. The UE 11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the UE 11 may be an internet of things UE such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things UE, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal), user agent (user agent), user device (user equipment), or User Equipment (UE). Alternatively, the UE 11 may be an unmanned aerial vehicle device. Alternatively, the UE 11 may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless communication device externally connected to the laptop. Alternatively, the UE 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

Access network device 12 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein access network device 12 may be an evolved access network device (eNB) employed in a 4G system. Alternatively, access network device 12 may be an access network device (gNB) in a 5G system that employs a centralized and distributed architecture. When access network device 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the access network device 12 is not limited by the embodiments of the present disclosure.

A wireless connection may be established between access network device 12 and UE 11 over a wireless air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

The core network devices may include, but are not limited to, at least one of: an access management function (Access Management Function, AMF) and/or a session management function (Session Management Function, SMF) and/or a user plane function (User Plane Function, UPF).

As shown in fig. 3A, the network device antenna configuration for SBFD is as follows:

for DL time units, configuring K transmit radio frequency chains (Tx Chain) for DL transmission; for example, a transmitter Unit (TxRU) group #1 and group #2 2K/2 transmit radio chains for DL transmission. An antenna radio frequency chain may correspond to one or more antenna elements (elements) within a group of antenna panels (panels).

For the SBFD time unit, K/2 transmit radio chains (Tx Chain) are configured for DL transmission and K/2 receive radio chains (Rx Chain) are configured for UL reception.

For UL time units, K receive radio chains (Rx Chain) are configured for UL reception.

In a wireless communication system, a network device indicates a beam used by the network device, and a UE determines a receiving beam corresponding to downlink reception of the UE according to a transmitting beam of the network device; and/or determining a transmitting beam for uplink transmission by the UE according to the receiving beam of the network equipment.

Obviously, the number of transmitting radio frequency chains for downlink transmission by the network device is different for the DL time unit and the SBFD time unit, so that the following difference may exist in the receiving beams of the UE on the DL time unit and the SBFD time unit:

the number of the wave beams of the network equipment in the DL and SBFD time units is different, so that the optimal wave beams of the same UE for downlink reception in the DL and SBFD time units are different;

the number of beams of the network device at DL and SBFD time slots is the same, but the network device has a difference in beam gain at DL and SBFD time units on the same beam, so that the optimal beams for downlink reception by the same UE at DL and SBFD time units are different.

At the same time, the network device may transmit and receive simultaneously on the SBFD time unit, and the UE may be interfered by UL signals transmitted from other UEs of the same network device or from UEs within other network devices when receiving DL signals.

As shown in fig. 3B, the interference of UL signals to DL signals may be referred to as cross-link interference between UEs (UE-UE Cross Link Interference, UE-to-UE CLI). To circumvent the stronger UE-to-UE CLI, the network device may select a different beam for DL transmission at the SBFD time unit than the DL time unit. This approach corresponds to suppression of UE-to-UE CLI by spatial isolation, and is referred to as spatial UE-to-UE CLI suppression.

In some cases, the beam transmitted on the SBFD time unit requires additional configuration to ensure the communication quality.

It is noted that the time units in this disclosure may be frames (subframes), slots (slots), mini-slots (mini-slots), sub-slots (subslots), transmission time intervals (transmission time interval, TTI), etc. The application is not limited thereto.

As shown in fig. 4A, an embodiment of the present disclosure provides an information processing method, where the method is performed by a user equipment UE, and the method includes:

s1110: and receiving beam indication information sent by the network equipment, wherein the beam indication information is used for indicating a beam transmitted by the sub-band full duplex SBFD time unit.

The UE may be any communication device as shown in fig. 2. Specific forms of the communication device may include a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an intelligent office device, an intelligent home device, and/or the like.

The network device may include, but is not limited to, the access network device shown in fig. 2. The access network device may be any of the access network devices described in fig. 2.

Illustratively, the SBFD time unit may include, but is not limited to, at least one of:

SBFD time slots;

SBFD minislots;

SBFD symbols;

an SBFD subframe;

SBFD radio frames, etc.

The SBFD time unit supports uplink transmission of the UE and also supports downlink transmission of the UE. The SBFD time unit can be flexibly used according to transmission requirements.

The beam indication information may be used for the UE to determine a candidate beam for uplink and/or downlink transmission at the SBFD time unit or a target beam determined from the candidate beams. The candidate beam is a beam candidate that can be transmitted on the SBFD time unit. The target beam is the beam that is ultimately used for transmission on the SBFD time unit. The target beam may be one or more of the candidate beams.

In some embodiments, the beam indication information includes at least one of:

transmitting configuration indication State (Transmission Configuration Indicator State, TCI-State) set information, wherein the TCI-State set information is used for indicating a beam set; wherein the set of beams includes one or more beams;

TCI-State Identification (ID) indicates the beam.

For example, the TCI-State set information may include at least an identification of the TCI-State set. As such, the beam indication information may indicate the candidate beam and/or the target beam for transmission of the SBFD time unit by way of the TCI-State set.

The set of TCI-states may include one or more TCI-states, one TCI-State may correspond to each beam. A TCI-State flag may indicate a beam.

In the embodiment of the disclosure, the beam dedicated for SBFD time unit transmission is determined by receiving the beam indication information sent by the network device, so that the beam used for SBFD time unit transmission may be different from the beam used for DL time unit or UL time unit transmission, so as to implement suppression of UE-to-UE CLI, and improve communication quality of SBFD time unit.

In some embodiments, the beam indication information includes at least one of:

candidate beam information included in a radio resource control (Radio Resource Control, RRC) message, wherein the candidate beam information is used to indicate candidate beams of the SBFD time unit;

a medium access Control (Media Access Control, MAC) Control Element (CE) comprising information related to beam activation, wherein the information related to beam activation is used for activating or deactivating at least one of the candidate beams;

Scheduling information included in the downlink control information (Downlink Control Information, DCI); wherein the scheduling information is used to schedule one or more activated beams for transmission of the SBFD.

Illustratively, the activated candidate beam is a candidate beam for an SBFD time unit or a candidate beam for a DL time unit.

Illustratively, as shown in fig. 4B, an embodiment of the present disclosure provides an information processing method, which is performed by a UE, the method including:

s1210: receiving an RRC message, the RRC message may include candidate beam information, wherein the candidate beam information indicates a candidate beam of the SBFD time unit;

s1220: receiving a MAC CE, which may include information related to beam activation; the information related to beam activation is used for activating or deactivating at least one candidate beam;

s1230: a DCI is received that may be used to schedule one or more activated beams for transmission of the SBFD.

In some embodiments, the RRC message is a configuration message for a candidate beam for transmission at SBFD time.

The MAC CE carries information related to beam activation, which may include activation information and/or deactivation information. Activation information for activating one or more candidate beams of the RRC message configuration. The deactivation information may be used to deactivate one or more activated candidate beams. It will be appreciated that: after the UE receives the first MAC CE for a period of time, the UE receives the second MAC CE. The second MAC CE is different from the first MAC CE in information related to beam activation. It is understood that the UE determines the activated candidate beam from the first MAC CE. After receiving the second MAC CE, the activated beam information will be determined again from the second MAC CE. The first MAC CE and the second MAC CE may be used to activate some or all of the candidate beams.

If one of the alternative beams is ready for use after being activated, it may be selected to be the target beam for use by the SBFD time unit transmission.

The RRC message and the MAC CE belong to the high-layer signaling, and the DCI belongs to the physical layer signaling, and the method has the characteristics of small delay and the like. The DCI may be used to select a target beam for SBFD time unit transmission from one or more candidate beams activated by a MAC CE.

Illustratively, the number of candidate beams activated or deactivated by the MAC CE is less than or equal to the number of candidate beams configured by the RRC message.

Also exemplary, the number of target beams for DCI scheduling is less than or equal to the number of candidate beams for MAC CE activation.

In some embodiments, the RRC message, the MAC CE, and the beam indication information carried by the DCI may be bit maps; one bit in the bit map indicates one TCI-State. One TCI-State corresponds to one beam.

In this case, the number of candidate beams configured by the RRC message may be determined by the number of bits of the cells (Information Element, IE) carried by the RRC message. The number of candidate beams that a MAC CE can activate or deactivate may depend on the length of the MAC CE. The target beam for DCI scheduling may depend on the length of the DCI. The length of the DCI may be the number of bits the DCI contains.

In some embodiments, the beam indication information carried by the RRC message may indicate a set of TCI-states, where any one TCI-State in the set of TCI-states corresponds to one candidate beam. The RRC message performs candidate beam configuration in a TCI-State set manner, so that the signaling overhead of the RRC message can be reduced.

The information related to candidate beam activation carried by the MAC CE may be a bit bitmap indicating candidate beams in the TCI-State set. The length of the information related to the candidate beam activation carried by the MAC CE is equal to the number of TCI-State in the TCI-State set. The mth bit is used to indicate whether the TCI-State identified as m in the TCI-State set is a candidate beam.

The DCI carried field indicates that the mth candidate beam is used, and the target beam is confirmed according to the TCI-State identification of the mth candidate beam in the MAC CE and the TCI-State set configured by the RRC message, wherein the value of the field carried by the DCI is m.

The information related to candidate beam activation carried by the MAC CE may also indicate a TCI-State set, a TCI-State subset, and/or a TCI-State identifier, etc. For example, the RRC message configures a plurality of TCI-State sets, and the MAC CE may activate or deactivate a portion of TCI-State activation through information related to candidate beam activation. For another example, the RRC message configures a TCI-State set, and the MAC CE may activate or deactivate the TCI-State subset by information related to the candidate beam. One TCI-State subset may include one or more TCI-State in the TCI-State set. If the MAC CE performs activation or deactivation of the candidate beam by carrying TCI-State set information, TCI-State subset information (e.g., an identifier indicating the TCI-State subset), etc., signaling overhead of the MAC CE may be reduced.

The DCI may carry a TCI status identity or beam identity directly indicating a target beam selected from the activated candidate beams.

In this way, the configuration is performed through the RRC message, the MAC CE is activated or deactivated, and then the DCI is used to schedule, so that a transmit beam and/or a receive beam that are suitable for communication on the corresponding SBFD time unit may be selected as needed at different communication moments.

Of course, in some embodiments, both the RRC message and the MAC CE may carry a single TCI-State identifier, and/or a single beam identifier, to implement beam indication such as beam configuration, activation or deactivation of the SBFD time unit, and scheduling.

In some embodiments, the RRC message includes at least one of:

the RRC message includes first candidate beam information and second candidate beam information; the first candidate beam information is used for indicating candidate beams of a downlink DL time unit; the second candidate beam information indicating a candidate beam of the SBFD time unit;

or alternatively, the process may be performed,

the RRC message includes third candidate beam information, wherein the third candidate beam information is used for transmission of DL time units and the SBFD time units.

In the embodiment of the disclosure, one RRC message may carry both first candidate beam information and second candidate beam information, where the first candidate beam information indicates a candidate beam for DL time units and the second candidate beam information indicates a candidate beam for SBFD time units. In some embodiments, one RRC message may include two IEs for carrying the first candidate beam information and the second candidate beam, respectively. In other embodiments, an RRC message may include an IE carrying beam indication information, and different fields of the IE may be used to carry the first candidate beam information and the second candidate beam information, respectively.

Illustratively, the first candidate beam information comprises a TCI-State identity and the second candidate beam information comprises a TCI-State identity may be the same.

Illustratively, the first candidate beam information comprises a TCI-State identity and the second candidate beam information comprises a TCI-State identity that is different.

In some embodiments, the candidate beam configured by the RRC message may be a common candidate beam for DL time unit and SBFD time transmission. In this case, the RRC message may carry one IE indicating that all beams are candidates for both DL time units and SBFD time units.

Illustratively, the TCI-State identifications included in the third candidate beam information may be different from each other.

Illustratively, the IE may include, but is not limited to, a physical downlink shared channel configuration (Physical Downlink Shared Channel, PDSCH-Config) IE.

Of course, the above is merely an example of carrying beam indication information on the RRC message, and the specific implementation is not limited to this example.

In some embodiments, the number of candidate beams that the third candidate beam information can configure is greater than the number of candidate beams that the first candidate beam information can configure; and/or the number of the groups of groups,

the number of the candidate beams which can be configured by the third candidate beam information is larger than the number of the candidate beams which can be configured by the second candidate beam information.

Since the DL time unit and the SBFD time unit share the same candidate beam, the number of beams that the third candidate beam information can configure may be greater than the number of candidate beams that the first candidate beam information can configure and/or the number of beams that the third candidate beam information can configure may be greater than the number of candidate beams that the second candidate beam information can configure in order to candidate to distinguish between the DL time unit and the SBFD time unit for scheduling.

For example, if the first candidate beam information and the second candidate beam information can configure 128 candidate beams, the third candidate beam information can configure a number of candidate beams greater than 128. For example, the third candidate beam information may configure 256 candidate beams.

In some embodiments, in actual configuration, the number of candidate beams that the third candidate beam information can configure is greater than the number of candidate beams that the first candidate beam information can configure; and/or the number of the candidate beams which can be configured by the third candidate beam information is larger than the number of the candidate beams which can be configured by the second candidate beam information.

In summary, in the embodiment of the present disclosure, the configuration of the candidate beam may be performed on the SBFD time unit and the DL time unit simultaneously through one RRC message, which has the characteristics of a small number of RRC messages and small signaling overhead.

Notably, are: the candidate beams configured to DL time units in the embodiments of the present disclosure may also be candidate beams of F time units, and/or the candidate beams of DL time units that are activated may also be candidate beams of F time units; and/or, the beam scheduled for transmission to DL time units may also be used for transmission of F time units.

In some embodiments, the information related to beam activation includes:

first information related to beam activation carried by a first field of the MAC CE, where the first information is used to activate or deactivate a candidate beam of at least one DL time unit;

and second information related to beam activation carried by a second field of the MAC CE, where the second information is used to activate or deactivate at least one candidate beam for an SBFD time unit.

In some embodiments, one MAC CE may carry activation or deactivation information for candidate beams with both SBFD time units and DL time units.

Specifically, in the embodiments of the present disclosure, one MAC CE may include two independent fields for carrying first information and second information, respectively, and the first information may be used to activate or deactivate candidate beams of DL time units. The second information is used to activate or deactivate the candidate beam of the SBFD time unit. Both the first information and the second information may be bitmaps, two bit values of either bit of which may represent the activation or deactivation states, respectively.

In another embodiment, the MAC CE for DL time unit transmission candidate beam activation or deactivation is different from the MAC CE for SBFD time unit candidate beam activation or deactivation.

Activation or deactivation of candidate beams for SBFD time units and DL time units is achieved by two MAC CEs. In this way, the activation or deactivation of the candidate beams of the SBFD time unit and the DL time unit can be flexibly implemented by different MAC CEs according to the transmission requirements of the SBFD time unit and the DL time unit, channel conditions, and the like.

If two MAC CEs are used to activate or deactivate the candidate beams for the SBFD time unit and DL time unit, respectively, the transmission resources of the two MAC CEs may be different. The transmission resources may be frequency domain resources and/or time domain resources.

Illustratively, the candidate beam activated or deactivated MAC CE for the SBFD time unit on which to transmit; and/or a MAC CE for DL time unit transmission candidate beam activation or deactivation, at which DL time unit transmission is performed.

At this point, the network device needs to transmit a MAC CE for activating or deactivating the SBFD time unit candidate beam, which may then be transmitted on the SBFD time unit. The network device needs to transmit a MAC CE for activating or deactivating the DL time cell candidate beam, which may then be transmitted on the DL time cell. As such, the UE receives a MAC CE at the SBFD time unit, which may be considered to indicate activation or deactivation of the candidate beam of the SBFD time unit. The UE receives a MAC CE in a DL time unit, the MAC CE may be considered to indicate activation or deactivation of a candidate beam for the DL time unit.

In some embodiments, the bits of the MAC CE include a first type of bits and a second type of bits; the first type of bits are high-order bits of the second type of bits; or, the second type of bits is high order bits of the first type of bits;

the first type of bits carry the first information; and/or, the second type of bit carries the second information.

In the disclosed embodiment, one MAC CE is used to carry information related to candidate beam activation for both SBFD time units and DL time units.

In the disclosed embodiment, all bits of the MAC CE are divided into a first type of bits and a second type of bits. The first type of bits carry first information and the second type of bits carry second information.

Illustratively, one MAC CE may include 16 bytes, for a total of 128 bits. The first type of bits may be consecutive partial bits of the 128 bits, and likewise, the second type of bits may be consecutive partial bits of the 128 bits. The number of bits of the first type of bits and the second type of bits may be the same or different.

Assuming that one MAC CE includes 128 bits and that the first type bits and the second type bits bisect the 128 bits, the first type bits and the second type bits occupy 64 bits, respectively. Illustratively, if the first type of bit is the upper 64 bits of the 128 bits, the second type of bit is the lower 64 bits of the 128 bits. In this case, the first type of bits are the high order bits of the second bit. Also exemplary, if the first type of bit is the lower 64 bits of the 128 bits, the second type of bit is the upper 64 bits of the 128 bits. In this case, the first type of bits are the low order bits of the second type of bits.

In some embodiments, the MAC CE further comprises: an indication bit; the indication bit is used for indicating information related to beam activation contained in the MAC CE, and the information is aimed at an SBFD time unit or a DL time unit.

The MAC CEs for the SBFD time units and DL time units are different and the MAC CE will carry an indication bit indicating whether the current MAC CE is for an SBFD time unit or DL time unit. The indication bits may include one or more bits.

In this case, the MAC CE for the DL time unit is not limited to transmission on the DL time unit, and similarly, the MAC CE for the SBFD time unit is not limited to transmission on the SBFD time unit.

The scheduling information for the SBFD time unit and the DL time unit may be carried in one DCI or may be carried in different DCIs.

The network device may transmit multiple MAC CEs and may be implemented by retransmitting the MAC CEs when the network device wants to update the candidate beam for which the UE is activated. The content of the adjacent two MAC CEs carrying information related to beam activation is different.

In some embodiments, the RRC message, the MAC CE, and the beam indication information carried by the DCI may be bit maps; one bit in the bit map indicates one TCI-State identity. One TCI-State identity corresponds to one beam.

After the network device transmits the first MAC CE for a period of time, the activated candidate beam update for the DL time unit and/or SBFD time unit of the UE may be caused by transmitting the second MAC CE.

At this time, the network device needs to transmit a MAC CE for activating or deactivating the SBFD time unit candidate beam, and the MAC CE may be configured on the SBFD time unit. The network device needs to transmit a MAC CE for activating or deactivating the DL time cell candidate beam, which may be configured on the DL time cell.

In such an embodiment, K2 and K3 are not equal, and the range of values of K2 and K2 may be natural numbers or positive integers. K2 and K3 may be different offset values for DL time units and SBFD time units, respectively.

Illustratively, the beam field carries an index of at least one activated candidate beam. Illustratively, the activated candidate Beam is a candidate Beam for a DL time unit, the value of the Beam field is m, which indicates the mth candidate Beam of the activated candidate beams for the DL time unit in the MAC CE, and the Beam corresponding to the first Beam identification is confirmed according to the TCI-State identification of the mth candidate Beam for the DL time unit in the MAC CE as the first Beam identification, that is, beam #1+k2, in combination with the TCI-State for the DL time unit configured by the RRC message.

Illustratively, the beam identified by the third beam is at least one beam transmitting a third reference signal, and the second offset value has a third value; and/or, the beam identified by the third beam is at least one beam for transmitting a fourth reference signal, and the second offset value has a fourth value.

The RRC message configuration and the beam of the MAC CE activated PDSCH may include:

step 1: the RRC message configures multiple TCI-states for PDSCH use:

TCI-StatesToAddModList SEQUENCE (SIZE (1.) maxnoftcistates) OF TCI-State is arranged in PDSCH-Config cells, wherein maxnoftci-StatesPDSCH has a value OF 128. The maximum number of candidate beams that maxNrofTCI-statepdsch can support for PDSCH is 128.

The TCI-State contains a TCI-State identifier (TCI-StateId), and the TCI-State contains 1 SSB index or identifier NZP-CSI-RS-resource id of a non-zero power channel State indication reference signal (Non Zero Power Channel State Indication Reference Signal, NZP-CSI-RS). Assume that N TCI-State are configured.

Step 2: the MAC CE adopts variable length to activate M beams corresponding to TCI-State

5 bits indicate serving cell identity, ID

2 bits indicate the partial BandWidth identification (BandWidth Part ID, BWP ID)

N bits activate M TCI-State: the RRC message configures N TCI-State used by the physical downlink shared channel (Physical Downlink SharedChannel, PDSCH), and activates beams (bitmap value is 1) corresponding to M (M is less than or equal to 8) TCI-State from the N TCI-State in a bitmap (bitmap) mode, specifically, the value of the nth bit of the bitmap is 1, which indicates that candidate beams with the TCI-State mark of N are activated.

Step 3: the TCI field (3 bits) in the downlink control information format 1-1 (Downlink Control Information Format-1, DCI format 1-1) indicates the TCI-State used in M (less than or equal to 8) activated TCI-State, and the target beam used by PDSCH is determined according to the SSB or NZP-CSI-RS resource corresponding to the TCI-State. Specifically, the TCI field in DCI format 1-1 indicates an index of at least one activated candidate beam, and illustratively indicates an mth activated TCI-State, which indicates an mth activated TCI-State (index is m) in activated candidate beams in the activated MAC CE, and determines a target beam used by the PDSCH scheduled by DCI according to a TCI-State identifier corresponding to the mth activated TCI-State and TCI-State information configured by combining with an RRC message.

Illustratively, the 4,5,6,7,8,910,11 bit value in the bit map in the MAC CE is 1, which represents: the activate RRC message configures a candidate beam for PDSCH use for TCI-State identification 4,5,6,7,8,910,11 of the N TCI-states. The activated candidate beams with TCI-State identification 4,5,6,7,8,910,11 are indexed from small to large according to the TCI-State identification, and then the beam index values of these activated beams are 0,1,2,3,4,5,6,7. It will be appreciated that: the index values of TCI-State identification 4,5,6,7,8,910,11 for the activated beams are 0,1,2,3,4,5,6,7, respectively.

Considering that the number of transmission radio frequency chains (Tx Chain) of DL and SBFD time slots is different, the optimal beams may be different, and different NZP-CSI-RS resources or SSBs need to be used for beam management, where there is a difference in TCI-State identifiers corresponding to the optimal beams of DL and SBFD time slots.

The optimal beams for DL and SBFD slots are the same, but the NZP-CSI-RS resources or SSBs are different, where the NZP-CSI-RSNZP-CSI-RS resources or SSB indices are different and the TCI-State identities for DL and SBFD slots are different.

The optimal beams for DL and SBFD slots are different and the corresponding TCI-State identities are different.

Thus, the activated beams for transmission of DL slots and SBFD slots need to be indicated separately. The set of TCI-states activated by the MAC CE may have a certain effective delay when used for PDSCH transmission.

The MAC CE for activating or deactivating the TCI-State may be transmitted on the PDSCH. The hybrid automatic repeat request acknowledgement (hybrid automatic repeat-request acknowledgement, HARQ-ACK) corresponding to the PDSCH is sent on time slot n, and the MAC CE activated TCI-State identifies the corresponding beam slave time slotTake effect, wherein->When the value mu of the subcarrier spacing configuration (Subcarrier Spacing, SCS) is expressed, the number of slots included in one subframe (1 ms)>Such as μ=0,when SCS is equal to 15KHz, μ=0. SCS is not equal to 15KHz, μ=scs/15 KHz-1.

Where μ is the subcarrier spacing configuration of the PUCCH carrying HARQ-ACK.

Is k _mac Is within a Frequency domain Range (FR) 1, < ->The value of (2) is 0.

k _mac The value of (c) may be indicated by the cell K-Mac in the RRC message. If the cell K-Mac in the RRC message is not configured, then K _mac The value of (2) is 0.

The MAC CE activates the TCI-State for the active time delay of PDSCH transmission, the indicated TCI-State of DL and SBFD slots cannot be used correspondingly in DL and SBFD slots.

Exemplary:

referring to fig. 6A, the TCI-State corresponding to the optimal beam for slot #1 and slots #2-9 is different, and the optimal beam #a used in slot #1 and the optimal beam #b used in slot #2 are different.

The active beam set #a is used in the slot #1, and the beam #b is not included in the set #a.

The MAC CE of slot #1 indicates an activated beam set #b of the SBFD slot PDSCH, where the activated beam set #b includes an optimal beam #b, and the MAC CE takes effect in slot #5, and the PDSCH of slots #2,3, and 4 cannot use the optimal beam #b.

Fig. 6B is a schematic diagram of a MAC CE. Where one Oct represents 1 byte. The control resource set ID in fig. 6B identifies the control resource set. The control resource set is configured with the frequency domain resources of the PDCCH.
