Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information configuration method, an information configuration device, a terminal device, and a network device.

Background

In a New air interface (NR) multicast broadcast service (Multicast Broadcast Service, MBS), a group scheduling based method is supported for transmitting a multicast physical downlink shared channel (Physical downlink shared channel, PDSCH). Group scheduling refers to a group of User equipments (UEs, which may also be referred to as terminals) sharing a scheduling signaling (group-common) physical downlink control channel (Physical downlink control channel, PDCCH), scrambling using a group-based radio network temporary identifier (group common Radio Network Tempory Identity, G-RNTI), and scheduling a group-common PDSCH (scrambling using G-RNTI).

Embodiments of the present application are described below with reference to the accompanying drawings. The information configuration method, the information configuration device, the terminal equipment and the network equipment provided by the embodiment of the application can be applied to a wireless communication system. The wireless communication system may be a system employing a fifth generation (5th Generation,5G) mobile communication technology (hereinafter, simply referred to as a 5G system), and it will be understood by those skilled in the art that the 5G NR system is only an example and not a limitation.

Referring to fig. 1, fig. 1 is a block diagram of a network system to which an embodiment of the present application is applicable, as shown in fig. 1, including a User terminal 11 and a base station 12, where the User terminal 11 may be a User Equipment (UE), for example: the terminal side devices may be mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop computers), personal digital assistants (personal digital assistant, PDA for short), mobile internet devices (Mobile Internet Device, MID) or Wearable devices (webable devices), etc., and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present application. The base station 12 may be a 5G or later base station (e.g., a gNB, a 5G NR NB), or a base station in other communication systems, or referred to as a node B, and in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

First, based on the technical solution provided in the present application, some technical terms that may be involved will be described.

1. Quasi Co-Location (QCL).

QCL is a term of multi-antenna technology in New Radio (NR) technology, where two ports are considered to have a QCL relationship when the channel characteristics on the symbol of one antenna port can be deduced from the symbol of another antenna port. The type of QCL relationship is determined as follows:

QCL-TypeA, obtain the channel estimation information based on Doppler shift, doppler spread, average delay, delay spread;

QCL-TypeB, obtain the channel estimation information based on Doppler shift, doppler spread;

QCL-TypeC, obtaining measurement information such as RSRP based on Doppler shift and average time delay;

QCL-type, assisting UE beamforming based on spatial Rx parameters.

Between two ports having QCL relationship, the calculated channel parameter values may be borrowed from each other, for example, if reference signal 1 of port 1 and reference signal 2 of port 2 have QCL-TypeD relationship, the calculated spatial Rx parameter of reference signal 1 may be used for the spatial Rx parameter of reference signal 2. Thereby reducing the amount of calculation of the reference signal 2 to calculate the spatial Rx parameters.

Application of qcl in unicast.

Currently unicast transmission is implemented based on QCL relations through the following steps:

step 1: the upper layer configures K TCI-states (TCI states). The TCI-State parameter is used to characterize the configuration of a quasi co-sited relationship (also simply referred to as QCL relationship of reference signal and PDSCH) between one to two downlink reference signals and DMRSs of PDSCH.

The higher layers configure the QCL via TCI-State (e.g., configuration parameters TCI-statestoadmodlist). In unicast transmission, the relevant tci_state configuration is embodied in unicast PDSCH configuration information (PDSCH-Config) as follows:

unicast PDSCH configuration information PDSCH-Config

{

TCI-State configuration List (TCI-statesToAddModList) SEQUENCE (SIZE (1..64)) OF TCI-State

}

The above indicates that, for unicast tci_state, the number K of tci_states is up to 64 by configuring unicast PDSCH configuration information PDSCH-Config. In addition, each TCI-state has a corresponding ID identification, i.e., TCI-state-ID.

Step 2: the activation of the TCI-state is performed by the MAC-CE.

And the base station activates the K TCI-states in the step 1 through the MAC-CE, and the number M of the activated TCI-states is not more than 8.

It should be noted that: only after activation by MAC-CE, the base station can indicate and use the corresponding TCI-state through DCI (step 3).

Step 3: the TCI-state used is indicated by DCI.

In DCI, the used TCI state is indicated by a dynamic TCI (Transmission configuration indication) indication that takes up 3 bits, which may indicate up to 8 TCI-states (i.e., up to 8 TCI-states activated in step 2).

It should be noted that: in the existing unicast technology, a problem of effective activation of the MAC-CE is involved, that is, the TCI indicated by the default related DCI schedule is effective after the terminal confirms that the MAC-CE command is received for 3 ms. For example, the terminal receives PDSCH containing a TCI-state activation command at slot 0, the terminal sends an acknowledgement message to the base station (i.e. PDSCH is demodulated correctly) at slot 6, and the base station and the terminal consider that at slot 13, the base station sends unicast scheduling DCI, i.e. TCI-state activated by MAC-CE is applied.

However, the technical solutions of configuration, activation and application of unicast related transmission configuration indication state (TCI-state) cannot be directly applied to multicast, and the following drawbacks are found through research:

1. for a group of UEs (for example, UE1 and UE 2), if a configuration mode of a unicast related transmission configuration indication state (TCI-state) is adopted, and the base station needs to schedule each terminal separately, the base station may send media access control layer control units (MAC-CEs) to different UEs at different moments, so that the time for each UE in the group to correctly receive and feedback acknowledgement is different, and thus the effective time for activating the TCI-state calculated by different UEs in the group is also different;

2. For a group of UEs (e.g., UE1 and UE 2), the base station may have different numbers of retransmissions of PDSCH carrying MAC-CEs due to different channel conditions of different UEs, and may eventually cause different effective time of the active TCI-state calculated by different UEs in the group. Thus, the base station can influence the scheduling of the group PDSCH corresponding to the MBS of the group of UE, and further influence the processing of MBS service.

Based on analysis, the embodiment of the application provides an information configuration method, an information configuration device, terminal equipment and network equipment, which are used for solving the problems of configuration, activation and the like of TCI-state of multicast PDSCH.

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.

As shown in fig. 2, an embodiment of the present application provides an information configuration method, which is executed by a terminal device, and includes:

in step S201, configuration information indicating TCI status is received from the network device for transmission configuration of the multicast broadcast service MBS.

It should be noted that, the MBS is a multicast service or a broadcast service.

Step S202, determining the effective time of a first TCI state, so that the terminal equipment receives a physical downlink shared channel PDSCH corresponding to the MBS by using the first TCI state meeting the effective time.

It should be noted that, the first TCI state is a TCI state for MBS in the active state in the configuration information.

In particular, the validation time may be understood as the time that the TCI state in the active state can be used, and generally refers to the start time that the TCI state can be used.

Alternatively, the configuration information may be used to configure one or more TCI states, and in the case where only one of the configured TCI states is in an active state, the network device may indicate the TCI state used by the terminal device without separate scheduling signaling; in the case that there are a plurality (2 and more) of TCI states in an active state in the configured TCI states, the network device needs to indicate the TCI states used by the terminal device through the scheduling signaling, that is, in the case that the number of TCI states in the active state is greater than 1, the method further includes:

receiving a scheduling signaling sent by network equipment;

Of course, in the case that only one TCI state in the active state is configured in the configured TCI states, the network device may also carry the TCI state in the active state in the scheduling signaling, where the TCI state is the target TCI state in the active TCI states used by the terminal device.

It should be noted that, in the embodiment of the present application, by defining the configuration of the TCI state (which may also be represented by the TCI-state) in the MBS PDSCH scene and the implementation manner of activation, the communication flow is perfected, so that the valid time of activating the TCI-state calculated by different UEs in a group of UEs is ensured to be the same, and the broadcast and multicast services are facilitated to be transmitted by using the beamforming technology.

Alternatively, step S201 in the embodiment of the present application may be implemented in one of the following manners:

mode A11, receiving first PDSCH configuration information sent by network equipment, wherein the first PDSCH configuration information carries first TCI state configuration information, and a TCI state corresponding to the first TCI state configuration information is used for one or more of MBS transmission and unicast transmission;

it should be noted that, the first TCI state configuration information is used to configure any one TCI state.

In this case, the first PDSCH configuration information may be regarded as unicast PDSCH configuration information (may be referred to as unicast PDSCH configuration information), that is, the configuration of the TCI state for MBS transmission by multiplexing existing PDSCH configuration information configured in the TCI state for unicast.

It should be noted here that the TCI state typically configured in this case is applicable to unicast transmissions and/or MBS transmissions.

Optionally, the PDSCH configuration information is configured through higher layer signaling (radio resource control (RRC) message), and if the configuration information is usable for both MBS transmission and unicast transmission, the configuration information of the TCI state for MBS transmission is configured in unicast PDSCH configuration information (PDSCH-Config) as follows:

unicast PDSCH configuration information (PDSCH-Config)

{

}

As can be seen from the above configuration, the configuration TCI-state configuration list includes at least one TCI state, and since no transmission type indication is performed, each TCI state is used for both MBS transmission (which may also be understood as QCL relation indication of MBS PDSCH) and unicast transmission (which may also be understood as QCL relation indication of unicast PDSCH).

It should be noted here that, in order to ensure that the terminal capability does not increase, the maximum number of TCI states configured remains unchanged, that is, 64 TCI states, and of course, for a UE with high capability, in order to support multicast and unicast services, the number of TCI states configured may also be greater than 64 TCI states.

Further optionally, in this implementation, the first TCI state configuration information includes one of:

a111, a first identifier, where the first identifier is used to indicate that a corresponding TCI state in the first TCI state configuration information is used for MBS transmission and/or used for unicast transmission;

it should be noted that, in this case, the identification information is added to the TCI state configuration information corresponding to each TCI state, so as to indicate whether the corresponding TCI state is suitable for unicast transmission or MBS transmission, or is suitable for unicast transmission and MBS transmission.

The specific configuration mode can be as follows:

as can be seen from the above configuration, when the usage flag useflg is set to multicast, it means that the TCI-state is used for MBS transmission; when the usage identifier usefilg is set to unicast, the TCI-state is used for unicast transmission; further, if there is no relevant setting, it means that the method is used for both MBS transmission and unicast transmission;

a112, a first type parameter of the TCI state and a second type parameter of the TCI state, wherein the first type parameter is used for indicating that a corresponding TCI state in the first TCI state configuration information is used for unicast transmission, and the second type parameter is used for indicating that a corresponding TCI state in the first TCI state configuration information is used for MBS transmission;

In this case, a parameter (i.e., corresponding to a first type parameter) for configuring the QCL relation indication of the unicast PDSCH and a parameter (i.e., corresponding to a second type parameter) for configuring the QCL relation indication of the MBS PDSCH are allocated in the configuration information of the TCI state.

The specific configuration mode can be as follows:

as can be seen from the above configuration, 2 TCI-state parameters are configured: the first relation parameter (i.e. corresponding to the first type parameter or the second type parameter) is used for unicast and the second relation parameter (i.e. corresponding to the second type parameter or the first type parameter) is used for multicast; alternatively, the second relationship parameter is used for unicast and the first relationship parameter is used for multicast.

Mode a12, receiving second PDSCH configuration information sent by a network device, where the second PDSCH configuration information carries second TCI state configuration information, and a TCI state corresponding to the second TCI state configuration information is dedicated to MBS transmission;

it should be noted that, the second TCI state configuration information is used to configure any one TCI state.

It should be noted that, the second PDSCH configuration information in this case may be regarded as PDSCH configuration information of the MBS (may be referred to as MBS PDSCH configuration information), that is, the configuration of the TCI state for MBS transmission is performed by newly introducing PDSCH configuration information for performing TCI state configuration of the MBS. It should be noted here that the TCI state configured in this case is generally applicable only to MBS transmissions.

Optionally, the PDSCH configuration information is configured through higher layer signaling (RRC message), and the configured TCI state is only usable for MBS transmission of PDSCH, specifically, the configuration information of the TCI state for MBS transmission is configured in PDSCH configuration information (PDSCH-Config) of MBS, as follows:

MBS PDSCH configuration information PDSCH-Config-multicast

{

}

As can be seen from the above configuration, the TCI-state configuration list includes at least one TCI state, and each TCI state is only used for MBS transmission (also understood as QCL relation indication of MBS PDSCH).

Here, in this case, in order to keep the terminal capability from increasing, the maximum number of TCI states configured remains unchanged, that is, 64 TCI-states configured in unicast (PDSCH-Config) and the sum of the number of TCI-states configured in PDSCH configuration information (PDSCH-Config-multicast) of MBS do not exceed the capability of the UE (e.g., do not exceed 64).

In this case, the TCI state configured in PDSCH configuration information (PDSCH-Config-multicast) of the MBS should be different from the ID number of the TCI state configured in unicast for each ID number.

Optionally, when the TCI state configured by the network device is acquired, the terminal device should also confirm which TCI states are active, and specifically one of the following implementations may be adopted:

mode B11, receiving a first signaling sent by network equipment, and determining a TCI state in an activated state for MBS based on the first signaling;

in this case, the network device indicates which TCI states are active or inactive, and the terminal determines which TCI states are active according to the indication of the network device; further, in the case of the TCI state used for indicating activation in the first signaling, the terminal device determines at least one TCI state used for activation among the TCI states of the MBS and included in the first signaling as a TCI state in the activation state; in case that the deactivated TCI state is included in the first signaling, the terminal device determines at least one other TCI state among the TCI states for the MBS, except for the deactivated TCI state included in the first signaling, as a TCI state in an activated state.

It should be noted that, the first signaling may be carried in a PDSCH of a unicast schedule or a PDSCH of an MBS schedule, and the first signaling may be a medium access control layer control element (MAC CE).

Optionally, in one case, the first signaling includes at least one or more of the following:

b111, first indication information, wherein the first indication information is used for indicating MBS transmission and/or unicast transmission;

b112, an indication of activation and/or deactivation of TCI state.

It should be noted that, the format of the MAC-CE in this case is shown in fig. 3, and as shown in fig. 3, the MAC-CE used for multicast TCI status activation or deactivation is divided into two parts, namely, a MAC-CE header and a MAC-CE content, where:

MAC-CE header: taking 1 byte (Oct 1), a total of 8 bits, specifically:

b0 occupies 1 bit for distinguishing whether the MAC-CE is used for unicast transmission or multicast transmission, i.e., corresponding to the first indication information described above, for example, 0 represents used for multicast, 1 represents used for unicast, or 1 represents used for multicast, 0 represents used for unicast;

the serving cell ID occupies 5 bits, indicating the serving cell index number;

the BWP ID is used to indicate a BWP number in the serving cell, and when b0 indicates a MAC-CE that is multicast, the BWP number is a BWP number to which broadcast multicast service information is allocated.

MAC-CE content: a maximum of 8 bytes (Oct 2-9) are occupied, 64 bits in total, specifically:

each bit corresponds to an ID of one TCI-state, for example: t (0) represents the TCI-state with the identification number of 0, and T (60) represents the TCI-state with the identification number of 60;

Each bit indicates that the corresponding TCI-state is active or inactive, i.e., corresponding to the above indication information, e.g., 0 indicates deactivation, 1 indicates activation; or 1 for deactivation and 0 for activation.

That is, in this case, the terminal device determines whether the TCI state for multicast transmission is in an active state or a deactivated state according to the indication of b0 after receiving the MAC CE.

It should be noted here that, for b0 in the MAC-CE header, it is possible to use a control resource pool ID (CORESET pool ID, control resource set) representing unicast, the control resource pool ID is 0 or 1, and b0 is not used to distinguish between unicast and multicast MAC-CEs when the base station configures the control resource pool ID of unicast with id=1, depending on the configuration of the base station. Of course, the base station may also configure the indication b0 for distinguishing between unicast/multicast MAC-CEs or for distinguishing between different control resource pool IDs.

It should be further noted that, when the MAC-CE cannot be distinguished from being used for unicast or multicast, the determination that the MAC-CE is used for unicast or multicast may be performed in one of the following ways:

c11, if the MAC-CE is transmitted through unicast PDSCH, the MAC-CE is used for both unicast and multicast;

C12, if the MAC-CE is transmitted through the multicast PDSCH, the MAC-CE is used for multicast.

Optionally, in another case, at least one or more of the following are included in the first signaling:

b113, second indication information, wherein the second indication information is used for indicating whether the first signaling contains a TCI state for MBS;

b114, and indication of activation and/or deactivation of TCI state.

Alternatively, in this case, only if the second indication information is used to indicate that the first signaling includes TCI states for MBS, the indication information of activation and/or deactivation corresponding to each TCI state is included in the first signaling.

It should be noted that, this manner may be regarded as using a format enhanced by MAC-CE, specifically as shown in fig. 4, and as shown in fig. 4, the MAC-CE used for multicast TCI-state activation is divided into two parts, namely, a MAC-CE header and a MAC-CE content, where:

MAC-CE header: taking 1 byte (Oct 1), a total of 8 bits, specifically:

b0 occupies 1 bit, and is used for judging whether the MAC-CE contains multicast TCI-state activation or deactivation, namely corresponding to the second instruction information; for example, 1 indicates that multicast is included, 0 indicates that multicast is not included (i.e., only for unicast), or 0 indicates that multicast is included, and 1 indicates that multicast is not included;

The serving cell ID occupies 5 bits, indicating the serving cell index number;

the BWP ID is used to indicate a BWP number in the serving cell, and when b0 indicates a MAC-CE that is multicast, the BWP number is a BWP number to which broadcast multicast service is allocated.

MAC-CE content: the maximum occupies N+1 bytes, and the total is (N+1) multiplied by 8 bits, wherein N is configurable; specifically:

every two bytes are 1 pair, and comprise C0/R bits and TCI state ID identification;

the R bits (corresponding to the third indication information described above) are used to distinguish whether it is a unicast or multicast indication, i.e. corresponding to the indication information described above, for example: when b0 indicates that multicast is included, r=0 is denoted as unicast, r=1 is denoted as multicast, or r=1 is denoted as unicast, and r=0 is denoted as multicast.

Mode B12, determining a preset number of TCI states in the TCI states for MBS as TCI states in an activated state;

it should be noted that, in this case, it is not necessary to instruct by the network device which TCI states are active or inactive, and the terminal may determine which TCI states are active in a predetermined manner (e.g., protocol convention) based on the configuration information.

That is, this situation may be understood as a default activation, which means that after the terminal device receives the configuration information of the TCI-state of the multicast, the terminal and the base station consider that part or all of the configured TCI-state has been activated without being activated by the MAC-CE or other explicit method, and the terminal and the base station may use the configuration information when the multicast scheduling signaling DCI indicates the TCI information.

Optionally, the preset number satisfies:

b121, if the number of the TCI states for MBS indicated by the configuration information is smaller than or equal to a preset value, the preset number is equal to the number of the TCI states for MBS indicated by the configuration information;

that is, when the number of TCI-states configured is less than a certain threshold (i.e., a preset value, such as 8), the TCI-states of all multicast configurations may be considered as activated by default.

B122, if the number of TCI states indicated by the configuration information is greater than a preset value, the preset number is equal to the preset value;

that is, when the number of TCI-states configured is greater than a certain threshold (e.g., 8), the first M default activations of the TCI-states configured by multicast may be considered.

It should be further noted that, for the default activation manner, the number of TCI-states configuring multicast may be limited not to exceed a certain threshold number, for example, not to exceed 8, for simplifying the operation.

Optionally, the terminal device may determine the effective time of the first TCI state according to the indication of the network device, or may determine the effective time of the first TCI state according to a protocol agreed manner.

Specific implementations of step 202 of embodiments of the present application are described below, respectively.

1. The terminal device can determine the effective time of the first TCI state according to the indication of the network device

In one case, the first signaling includes TCI status indication information;

optionally, in this case, the implementation of step 202 is as follows:

In this case, TCI status indication (which may be understood as new TCI status indication (new TCI state indication, NTI)) information is added to the first signaling, and the effective time of the activated TCI status is determined based on the NTI mechanism, and the length of the NTI information is typically 1 bit, which is used to indicate the QCL relationship of the PDSCH, whether the last activated TCI-state is used or the previously activated TCI-state is used.

That is, if the new TCI state indication information in the received first signaling is flipped, the start time of the effective time of the TCI state in the active state is determined as the time of receiving the first signaling.

As shown in fig. 5, whether to use the newly activated TCI-sate set list may be determined by whether the NTI in the multicast scheduling signaling DCI is flipped, specifically:

the terminal receives the DCI in slot0, and NTI indicates 0; assume that TCI-state set List 0 is used;

the terminal receives the DCI in slot6, and NTI indicates 1; compared with the nti=0 of slot0, if the flip occurs, the TCI-state used by slot0 is not used, but an activated TCI-state set list (e.g. list a) received in the latest time is used, where the TCI-state set list refers to a TCI-state set list contained in configuration information corresponding to a TCI state;

the terminal receives the DCI in slot12, and NTI indicates 1; no rollover occurs compared to nti=1 for slot6 and slot6 uses the same active TCI-state set list (e.g., list a).

Here, the new active TCI-state set list used by slot6 may be a MAC-CE including TCI-state activation received before slot6, or may be a MAC-CE including TCI-state activation received before slot 0.

Further: the above procedure can also be described as:

When the value of the NTI indicated by the scheduling signaling DCI is the same as the value of the NTI indicated by the last DCI (called NTI is not flipped), the same TCI-state set list is used as the last DCI. When the value of the NTI indicated by the scheduling signaling DCI is different from the value of the NTI indicated by the last DCI (called NTI flip), a different TCI-state set list is used with the last DCI, for example, a newly activated TCI-state set list is used.

For the UE to receive the first DCI information, the NTI is considered to be flipped.

In another case, the first signaling includes validation indication information;

optionally, in this case, the implementation of step 202 is as follows:

it should be noted that, the validation instruction information includes at least one of the following:

time slot numbering;

a subframe number;

and (5) wireless frame numbers.

In this case, the indication information (corresponding to the above-mentioned validation indication information) of the validation time of the MAC-CE is added to the MAC-CE activated by the transmission TCI-state, and the validation time may be expressed as an absolute time, a slot number, a subframe number, and a frame number; or a combination of time slots and radio frame numbers, or a combination of subframes and radio frame numbers.

The following description will take radio frame numbers and subframe numbers as examples.

As shown in fig. 6, the indication information for increasing the effective time in the MAC-CE is represented by 8 bits; where the first 4 bits represent the radio frame number (10 ms duration per radio frame) and the last 4 bits represent the subframe number (1 ms duration per subframe). After the terminal equipment reads the related parameters, the manner of determining the effective time for activating the TCI-state is as follows:

d121, calculating the effective starting time wireless frame number: and when the partial digit value (such as the bit value) of the radio frame number is the same as the radio frame number value indicated by the MAC-CE, the radio frame number is the radio frame number with the MAC-CE activated and validated.

Such as: the time slot of PDSCH corresponding to MAC-CE received by terminal 1 assumes the radio frame number: 510 (decimal value), MAC-CE indicated as 7; the radio frame number of the MAC-CE activation validation is 517, namely 7 radio frames later validation;

such as: the time slot of the PDSCH corresponding to the MAC-CE received by the terminal 2 is the wireless frame number: 508 (decimal value), MAC-CE indicated as 7; because the radio frame number of the group corresponding to the radio frame number 508 does not appear in the radio frame number of the unit number of 7, the terminal equipment needs to determine the effective time in the next group of radio frames, and the radio frame number of the MAC-CE activation effect is 517; i.e. 9 radio frames later take effect;

D122, calculating the effective starting time wireless subframe number: when the bit value of the wireless subframe number is the same as the subframe number value indicated by the MAC-CE, the bit value is the wireless subframe number effective by the activation of the MAC-CE;

it should be noted that, the usage in this case is the same as the D121 principle, and will not be described here again.

Here, it should be noted that, the first signaling in the case where the terminal device determines the effective time of the first TCI state according to the indication of the network device may be a signaling carrying identification information of the activated or deactivated TCI state (i.e., the first signaling includes not only the identification information of the activated or deactivated TCI state but also the effective indication information or the TCI state indication information); alternatively, the first signaling may be signaling that does not carry identification information of the activated or deactivated TCI state (i.e., only validation indication information or TCI state indication information is included in the first signaling at this time)

2. Determining the effective time of the first TCI state according to the protocol contract

In one case, the implementation of step 202 is as follows:

It should be noted that, in this manner, the determination of the validation time is performed in a predetermined manner (e.g., a protocol convention), and in this case, a time window mechanism needs to be introduced, for example, when the terminal receives the MAC-CE activating the TCI-state in the time window n, the start time of the validation time is the start position of the next time window or the start position of the time window located a plurality of time windows spaced from the time window n after the time window.

In particular, the window length of the time window and the window offset are typically configured by the network device.

It should be noted that this case is applicable to a scenario in which the identification information of the TCI state is indicated by the first signaling for activation or deactivation.

As shown in fig. 7, assuming that the time window set by the network device is 20ms (the period T is also 20 ms), UE-1 correctly receives the TCI-state activated MAC-CE at slot 2 of window n; UE-2 correctly receives TCI-state activated MAC-CE at slot 11 of window n.

Although multicast scheduling signaling is received on both slot 6 and slot 14 of window n, neither is the list of TCI-state activations received on window n applied. The UE-1/UE-2 receives the multicast scheduling signaling on slot 21 of the next window (n+1), and then applies the TCI-state activated list received at window n.

In another case, the implementation of step 202 is:

It should be noted that this case is generally applicable to the case of default activation of the TCI state, where the default activated TCI state is immediately validated.

Optionally, in case the network device sends a scheduling signaling, the scheduling signaling is a multicast scheduling signaling or a broadcast scheduling signaling, the scheduling signaling includes a TCI indication, and the TCI indication is used to indicate a QCL relation of the multicast PDSCH or a QCL relation of the broadcast PDSCH, i.e. which activated TCI state is specifically used.

Here, it should be noted that, in the TCI-state configuration of step 201, if the MBS and the unicast share configuration, the TCI-state list used by the MBS to schedule the DCI is the same as that used by the unicast; if the TCI-states of the MBS are configured separately in step 201, the TCI-state list used by the MBS scheduling DCI uses the separately configured and activated TCI-states.

It should be noted that, for the configuration of the validation time, the terminal device and the network device should have the same understanding, and when the network device determines the validation time of the TCI in the active state by itself according to the protocol, the validation time needs to be indicated to the terminal device through signaling; if the network device does not indicate the effective time to the terminal device through signaling, the network device and the terminal device both determine the effective time by themselves in a protocol-agreed manner. Likewise, for the configuration of the TCI state in the active state, the terminal device and the network device should have the same understanding, and when the network device decides the TCI state in the active state by itself according to the protocol, the TCI state in the active state needs to be indicated to the terminal device through signaling; if the network device does not indicate the TCI state in the active state to the terminal device through signaling, the network device and the terminal device both determine the configuration of the TCI state in the active state by adopting a protocol agreed mode.

It should be noted that, the embodiment of the application provides a mode of configuring, activating and validating PDSCH TCI-state when transmitting broadcast multicast service based on group scheduling, which solves the problems of configuring, activating and validating TCI-state based on group UE; therefore, the effective time of the activated TCI-state calculated by different UE in a group of UE is ensured to be the same, and the broadcast and multicast service is favorably transmitted by utilizing the beam forming technology.
