Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Fig. 1 is one of flow diagrams of an information transmission method provided in the embodiment of the present application, and as shown in fig. 1, the embodiment of the present application provides an information transmission determining method, where an execution body may be a UE in an MBS group, for example, a mobile phone or the like. The method comprises the following steps:

step 101, determining a target space receiving parameter.

Specifically, before the UE in the MBS group receives MBS information on the PDSCH, it is first necessary to determine spatial reception parameters for receiving the MBS information.

In the embodiment of the application, the space receiving parameter of the MBS information received by the UE in the MBS group adopts QCL type-D type TCI indication. The spatial reception parameters may be beam directions, QCL hypotheses, and other parameters for assisting UE beamforming, which are not described herein.

In some embodiments, the UE determining the target space reception parameters includes:

determining a target space receiving parameter based on the first duration and a first threshold value; the first time length is the time length between the time of receiving the target DCI and the time of scheduling the PDSCH; the target DCI is used to schedule the PDSCH; the first threshold value is a reference value of the duration of the QCL; the reference value is determined by the network equipment according to the duration of QCL sent by all terminals in the MBS group or according to protocol convention;

Or alternatively, the process may be performed,

the target space reception parameters are determined according to a protocol convention.

Specifically, the PDSCH refers to a PDSCH scheduled by the target DCI. The target DCI is used to schedule the PDSCH, and refers to a time-frequency resource of the PDSCH that includes MBS information. The UE may determine a time to schedule the PDSCH according to the target DCI. The time difference between the time of receiving the target DCI and the time of scheduling the PDSCH is the first duration.

In some embodiments, the UE determining the target space reception parameter based on the first time duration and the first threshold value comprises:

under the condition that the first time length is smaller than the first threshold value, taking the space receiving parameter used by receiving the target DCI as the target space receiving parameter;

Specifically, the UE in the MBS group receives DCI for scheduling the PDSCH, i.e., target DCI, on a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and if the first time length is less than the first threshold value, the UE uses a spatial reception parameter used for receiving the target DCI as the target spatial reception parameter.

In the case that the first time period is greater than or equal to the first threshold value, the UE may determine the target spatial reception parameter according to the received first information sent by the network device.

The first information may be DCI or RRC information. For example, the TCI field in the target DCI may be carried, and may be carried by other DCIs.

The UE may also determine the target spatial reception parameter according to a protocol convention if the first time period is greater than or equal to the first threshold value. Determining the target space reception parameter by protocol convention means that specific content of the target space reception parameter is pre-defined in the protocol, or specific rules for determining the target space reception parameter are pre-defined in the protocol. And the target space receiving parameters are determined according to protocol convention without interaction between UE and network equipment, so that signaling resources are saved.

In some embodiments, the spatial reception parameters used to receive the target DCI are associated with a target control resource aggregate set CORESET for listening to the target DCI.

Specifically, the spatial reception parameter used for receiving the target DCI may be a spatial reception parameter associated with a target Control Resource SET (CORESET) in a target slot closest to the current time; the target time slot is a time slot for monitoring a PDCCH carrying the target DCI; the target core is the core with the minimum index value for monitoring the target DCI in the target time slot.

Fig. 2 is a schematic diagram of a spatial reception parameter determination manner provided in the embodiment of the present application, as shown in fig. 2, both DCI1 and DCI2 are used for scheduling PDSCH, where DCI1 is carried on PDCCH1, DCI1 is used for scheduling PDSCH1, DCI2 is carried on PDCCH2, and DCI2 is used for scheduling PDSCH2. Assuming that the current UE needs to receive MBS information on PDSCH1, PDCCH2 is the PDCCH of the time slot closest to the current time from the time domain perspective, where (a) shows the case where the first time length is smaller than the first threshold value, in this case, the beam direction used by the UE to receive MBS information on PDSCH1 is the same as the beam direction corresponding to CORESET with the minimum index value used when the UE receives DCI2 on PDCCH 2.

In the figure, (b) shows a case where the first time period is greater than or equal to the first threshold, and in this case, the beam direction used by the UE to receive MBS information on PDSCH1 is indicated by DCI 1.

It should be noted that: in fig. 2, the beam direction is taken as an example of the spatial reception parameter, and other types of spatial reception parameters and the above examples are not illustrated in detail.

For example: the spatial reception parameters used for receiving the target DCI are obtained in the beam direction of the last slot, lowest control Resource Set Id in the MO of the PDCCH scheduling MBS (i.e. the beam direction with the lowest CORESET index value in the detection slot of the PDCCH nearest to the primary).

under the condition that the first time length is smaller than the first threshold value, determining the target space receiving parameter according to high-level signaling sent by network equipment;

Specifically, the UE in the MBS group receives the target spatial reception parameter sent by the network device through higher layer signaling.

In the case that the first time length is smaller than the first threshold value, the UE may determine the target space receiving parameter according to the received higher layer signaling sent by the network device.

For example, the network device sends a higher layer signaling to all UEs in the MBS group, where the higher layer signaling includes the target spatial reception parameter, and the UE parses the target spatial reception parameter from the received higher layer signaling.

The higher layer signaling may be RRC signaling.

In some embodiments, the UE determining the target spatial reception parameter according to higher layer signaling sent by the network device includes:

Acquiring the high-level signaling; the high-level signaling is used for indicating candidate space receiving parameter sets;

selecting the target space receiving parameter from the candidate space receiving parameter set; the target spatial reception parameter is a spatial reception parameter corresponding to the first or last index value in the candidate spatial reception parameter set.

Specifically, in the embodiment of the present application, the network side device configures, through higher layer signaling, a candidate spatial reception parameter set, where the candidate spatial reception parameter set includes one or more spatial reception parameters or index values/identifiers of the spatial reception parameters.

After the UE acquires the higher layer signaling, the candidate spatial reception parameter set is determined.

The UE then selects the target spatial reception parameter from the set of candidate spatial reception parameters.

Specifically, the UE may select, from the candidate set of spatial reception parameters, a spatial reception parameter corresponding to the first index value as the target spatial reception parameter, or may select, from the candidate set of spatial reception parameters, a spatial reception parameter corresponding to the last index value as the target spatial reception parameter. The first or last is specifically selected, and may be configured by the network device, or may be agreed by a protocol, which is not limited herein.

acquiring the high-level signaling; the high-level signaling is used for indicating a target index value in the candidate space receiving parameter set;

Specifically, in the embodiment of the present application, the network side device directly configures the target space receiving parameter for the UE through the higher layer signaling.

The network device may send the higher layer signaling to the UE; the higher layer signaling is used to indicate a target index value in the candidate set of spatial reception parameters.

And the UE acquires the high-layer signaling and analyzes the high-layer signaling to determine a corresponding target index value of the target space receiving parameter in the candidate space receiving parameter set.

The UE can determine the target space receiving parameter according to the target index value.

The candidate spatial reception parameter set may be configured by the network device, or may be agreed by a protocol, which is not limited herein.

The UE may also determine the target spatial reception parameter according to a protocol convention if the first time period is greater than or equal to the first threshold value. Determining the target space receiving parameters by protocol conventions saves signaling resources.

In some embodiments, further comprising:

acquiring the first threshold value configured by the network equipment;

or alternatively, the process may be performed,

the first threshold value is determined according to a protocol convention.

Specifically, in the embodiment of the present application, the reference value of the duration of the QCL is different from the duration of the QCL used when the UE determines the spatial reception parameter in the unicast scenario (the duration of the QCL is associated with the capability of the UE, and the capability of different UEs may be different, and in the unicast scenario, the duration of the QCL used when different UEs determine the spatial reception parameter may be different), and in the MBS scenario, all UEs in the MBS group use a unified duration of the QCL, which is referred to as the reference value of the duration of the QCL, that is, the first threshold value.

The first threshold value may be configured by the network device.

Firstly, the UE in the MBS group reports the capability information of the UE, wherein the capability information comprises the duration of QCL supported by the UE. The UE may report its own capability information using RRC signaling, or may report it through other signaling, which is not limited herein.

The network equipment acquires the capability information reported by all the UE in the MBS group, and the network equipment determines a reference value of the duration of the QCL, namely a first threshold value, according to the duration of the QCL in the capability information reported by all the UE.

In some embodiments, in a case where the first threshold is configured for the network device, the first threshold is a maximum value of duration of QCL sent by all terminals in the MBS group.

Specifically, the network device selects the maximum value of the duration of the QCL in the capability information reported by all UEs as the reference value of the duration of the QCL, i.e. the first threshold value.

After the network device determines the first threshold, the first threshold is sent to all UEs in the MBS group through configuration signaling. The configuration signaling may be RRC signaling or the like, specifically, through which configuration signaling is sent, which is not limited herein.

For example, the network device may configure the first threshold based on common frequency domain resources (Common Frequency Range, CFR).

The UE then obtains the first threshold value for the network device configuration.

In addition, the first threshold value may be predetermined by a protocol. All UEs in the MBS group may determine the first threshold according to a protocol convention. Determining the first threshold value by protocol conventions saves signaling resources.

For example, the UE may use the maximum value of the set of duration of candidate QCLs specified by the network device or protocol as the first threshold. The set of duration of the candidate QCL specified by the network device or protocol may be the set of symbol numbers {7,14,28}, or {14,28}, or {28,56}.

It should be noted that: determining the first threshold value by protocol conventions may be understood in two ways: 1. the protocol pre-agrees with a field corresponding to the first threshold value in the configuration signaling, for example, the RRC signaling agrees with a field timeduration for qcl_ref for indicating the first threshold value, but the network device does not assign a value to the field, that is, although the configuration signaling is acquired in the MBS group, the first threshold value cannot be resolved, and in this case, the first threshold value agreed in advance by the protocol is used; 2. the protocol agrees that the field corresponding to the first threshold value is not added in the configuration signaling any more, and the first threshold value is directly agreed by the protocol, so that signaling resources can be saved.

The target space receiving parameter is determined according to the first information.

Specifically, in the embodiment of the present application, the target space receiving parameters used by the UE in the MBS group to receive the MBS information on the PDSCH are configured by the network device.

First, the network device transmits first information to UEs in the MBS group, the first information indicating the target spatial reception parameter.

The UE in the MBS group acquires first information sent by the network equipment.

After the UE in the MBS group acquires the first information, the first information is analyzed, and the target space receiving parameter is determined.

Step 102, receiving MBS information on PDSCH according to the target space receiving parameter.

Specifically, after determining the target space reception parameter, the UE in the MBS group receives MBS information on the PDSCH according to the target space reception parameter.

According to the information method provided by the embodiment of the application, the UE in the MBS group firstly determines the target space receiving parameter in a unified mode, and then receives the MBS information on the PDSCH according to the unified target space receiving parameter, so that the normal operation of MBS service is ensured.

Fig. 3 is a second flowchart of an information transmission method according to an embodiment of the present application, as shown in fig. 3, where an execution body of the information transmission method may be a network device, for example, a base station, and the method includes:

Step 301, determining a target space transmission parameter.

In the embodiment of the application, the space transmission parameters used when the network equipment transmits the MBS information to a plurality of UEs in the MBS group on the PDSCH correspond to the space receiving parameters used when the UEs in the MBS group receive the MBS information on the PDSCH, thereby ensuring the normal operation of MBS service.

The spatial transmission parameters may be beam directions, QCL hypotheses, etc., and may also be parameters of beam forming of other auxiliary network devices, which are not described herein.

In some embodiments, the network device determining the target space transmission parameters includes:

or alternatively, the process may be performed,

and determining the target space transmission parameters according to protocol conventions.

Specifically, in the embodiment of the present application, the spatial transmission parameter used when the network device transmits the MBS information to the plurality of UEs in the MBS group on the PDSCH may be determined by the network device according to the duration of the QCL transmitted by all the terminals in the MBS group, or may be agreed by the network device according to a protocol.

In some embodiments, the network device determines a first threshold value, comprising:

and acquiring the duration of the QCL transmitted by all the terminals in the MBS group, and determining the first threshold according to the duration of the QCL transmitted by all the terminals in the MBS group.

Specifically, in the embodiment of the present application, the network device determines the first threshold according to the duration of QCL sent by all terminals in the MBS group, and specifically includes the following steps:

Then, the network equipment acquires the capability information reported by all the UEs in the MBS group, and the network equipment determines a reference value of the duration of the QCL, namely a first threshold value, according to the duration of the QCL in the capability information reported by all the UEs.

In some embodiments, in a case where the first threshold is determined according to the duration of QCL transmitted by all terminals in the MBS group, the first threshold is the maximum value of the duration of QCL transmitted by all terminals in the MBS group.

In some embodiments, the network device determines the first threshold value according to a protocol convention.

Specifically, the first threshold value can be determined by protocol convention in advance, and the UE in the MBS group does not need to report the capability information, so that signaling resources are saved.

For example, the network device may use the maximum value of the set of duration of the candidate QCL specified by the system (protocol) as the first threshold.

In some embodiments, the network device determining the target space transmission parameter based on the first time duration and the first threshold value includes:

under the condition that the first time length is smaller than the first threshold value, taking the space transmission parameter used for transmitting the target DCI as the target space transmission parameter;

In the case that the first time period is greater than or equal to the first threshold value, the network device may determine the target space transmission parameter according to a protocol convention. Determining the target space transmission parameter by protocol convention means that specific content of the target space transmission parameter is pre-defined in the protocol, or specific rules for determining the target space transmission parameter are pre-defined in the protocol.

In some embodiments, in the case where the target spatial transmission parameter is determined according to a protocol convention, the target spatial transmission parameter is a spatial transmission parameter corresponding to a first or last index value in the candidate spatial transmission parameter set; or the space transmission parameter corresponding to the target index value in the candidate space transmission parameter set.

Specifically, if the network device determines the target spatial transmission parameter according to the protocol convention, the target spatial transmission parameter may be a spatial transmission parameter corresponding to a first index value in the candidate spatial transmission parameter set, or may be a spatial transmission parameter corresponding to a last index value in the candidate spatial transmission parameter set.

Wherein the candidate space transmission parameter set is pre-agreed by the protocol.

Step 302, multicast and broadcast service MBS information is sent on the physical downlink shared channel PDSCH according to the target space sending parameter.

Specifically, after determining the target space transmission parameter, the network device transmits MBS information to all UEs in the MBS group on the PDSCH according to the target space transmission parameter.

In some embodiments, further comprising:

Specifically, after determining the target space transmission parameter, the network device may also send the determined target space transmission parameter to all terminals in the MBS group.

All terminals in the MBS group receive the first information sent by the network equipment, analyze the first information, determine the target space sending parameter, and further determine the target space receiving parameter corresponding to the target space sending parameter, thereby ensuring the normal operation of MBS service.

According to the information method provided by the embodiment of the application, after the network equipment determines the target space transmission parameters, MBS information is transmitted to the UE in the MBS group on the PDSCH according to the target space transmission parameters, the UE in the MBS group firstly determines the target space receiving parameters in a unified mode, and then receives the MBS information on the PDSCH according to the unified target space receiving parameters, so that the MBS service is ensured to be normally carried out.
