Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Fig. 1 shows a flow diagram of a communication method according to an embodiment of the present disclosure. The method is applied to a terminal Device, such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and the specific type of the terminal Device is not particularly limited by the disclosure.

As shown in fig. 1, the method may include:

step S11, receiving Downlink Control Information (DCI), where the DCI includes pre-preemption indication Information (pre-preemption indication) of a serving cell, the preemption indication Information is used to indicate a time-frequency resource not transmitting first service data, and the serving cell includes a plurality of TRPs.

In step S12, a target TRP corresponding to the preemption indication information among the plurality of TRPs is determined.

When the network side device needs to preempt a part of time-frequency resources for transmitting the first service data in a process of transmitting the first service data to the terminal device, for example, the preempted part of time-frequency resources is used to transmit the second service data, so as to meet a low-latency requirement of the second service data, the network side device may send DCI to the terminal device, where the DCI includes preemption indication information of a serving cell, and the preemption indication information is used to indicate time-frequency resources for not transmitting the first service data.

In one possible implementation, the DCI may be DCI format 2_ 1.

In a possible implementation manner, the DCI may include preemption indication information of one serving cell, or the DCI includes preemption indication information of each serving cell in a plurality of serving cells.

For example, the DCI includes preemption indication information for each of N serving cells: the system comprises pre-occupancy indication1, pre-occupancy indication 2, … … and pre-occupancy indication N, wherein the pre-occupancy indication1 is the preemption indication information of a service cell 1, the pre-occupancy indication 2 is the preemption indication information of the service cell 2, and the … … and the pre-occupancy indication N are the preemption indication information of the service cell N.

For each serving cell, when the serving cell includes a plurality of TRPs, the network side device may add, to DCI transmitted to the terminal device, a transmission receiving point indication (TRP indication) corresponding to the serving cell, which is used to indicate a target TRP corresponding to the preemption indication information in the plurality of TRPs of the serving cell, so that the terminal device may determine, according to the TRP indication included in the received DCI, the target TRP corresponding to the preemption indication information of the serving cell, that is, determine that there is a target TRP that preempts a part of time-frequency resources of the first service data, and then accurately decode the target TRP in a communication link corresponding to the target TRP, thereby effectively improving the decoding performance of the terminal device. The present disclosure does not specifically limit the number of target TRPs.

For example, the DCI includes: the mobile terminal comprises a pre-occupation indication a and a TRP indication a, wherein the pre-occupation indication a is occupation indication information of a serving cell a, and the TRP indication a is used for indicating a target TRP corresponding to the pre-occupation indication a in a plurality of TRPs of the serving cell a.

When the DCI includes the preemption indication information for each of the N serving cells, the positions of the TRP indications corresponding to each serving cell added to the DCI include, but are not limited to, the following two ways.

The first method comprises the following steps: TRP indication is inserted between two adjacent pre-indication indications.

For example, the DCI includes: pre-indication 1, TRP indication1, pre-indication 2, TRP indication 2, … …, pre-indication N, TRP indication N. The pre-indication 1 is preemption indication information of the serving cell 1, and the TRP indication1 is used for indicating a target TRP corresponding to the pre-indication 1 in a plurality of TRPs of the serving cell 1; pre-occupation indication 2 is occupation indication information of the serving cell 2, and the TRP indication 2 is used for indicating a target TRP corresponding to the pre-occupation indication 2 in a plurality of TRPs of the serving cell 2; … …, respectively; the pre-occupancy indication N is occupied indication information of the serving cell N, and the TRP indication N is used for indicating a target TRP corresponding to the pre-occupancy indication N in a plurality of TRPs of the serving cell N.

And the second method comprises the following steps: TRP indication was inserted after all pre-indication indications.

For example, the DCI includes: pre-indication 1, pre-indication 2, … …, pre-indication N, TRP indication1, TRP indication 2, … …, TRP indication N. Wherein, pre-occupation indication1 is the occupation indication information of the service cell 1, pre-occupation indication 2 is the occupation indication information of the service cell 2, … …, and pre-occupation indication N is the occupation indication information of the service cell N; the TRP indication1 indicates a target TRP corresponding to the pre-estimation indication1 among the plurality of TRPs of the serving cell 1, the TRP indication 2 indicates a target TRP corresponding to the pre-estimation indication 2 among the plurality of TRPs of the serving cell 2, … …, and the TRP indication N indicates a target TRP corresponding to the pre-estimation indication N among the plurality of TRPs of the serving cell N.

Specific forms of the TRP indication corresponding to each serving cell added to the DCI include, but are not limited to, the following two ways.

The first method comprises the following steps: the TRP indication is TRP indication information.

In one possible implementation manner, determining a target TRP corresponding to the preemption indication information in the plurality of TRPs includes one of: when the TRP indication information is included in the DCI, determining the TRP indicated by the TRP indication information as a target TRP; when the TRP indication information is not included in the DCI, determining each of the plurality of TRPs as a target TRP.

Wherein the TRP indication information comprises at least one of the following: a Transmission Configuration Indication state index (TCI state index), a Reference signal group Indication/index (RS grouping Indication/index).

One TCI state index corresponds to one TRP, and one RS grouping indication/index corresponds to one TRP.

For example, 3 TRPs are included in serving cell a: TRP 0, TRP 1 and TRP 2, wherein TRP 0 corresponds to TCI state index 0, TRP 1 corresponds to RS grouping indication1, and TRP 2 corresponds to TCI state index 2.

If the DCI sent by the network side device and received by the terminal device includes: the terminal equipment can determine that target TRP corresponding to the pre-estimation indication a in a serving cell a is TRP 0 and TRP 2;

if the DCI sent by the network side device and received by the terminal device includes the pre-indication a but does not include the TRP indication a, the terminal device may determine that the target TRP corresponding to the pre-indication a in the serving cell a is TRP 0, TRP 1, and TRP 2.

And the second method comprises the following steps: TRP indication is the TRP indicator signaling domain.

Wherein, the bit number of the TRP indication signaling domain is the number of TRPs in the serving cell.

For example, 3 TRPs are included in serving cell a: the terminal device receives DCI sent by the network side device, and the DCI comprises TRP 0, TRP 1 and TRP 2: pre-emphasis indication a and TRP indication a, wherein TRP indication a is a 3-bit (bit) TRP indication signaling domain.

If the domain value of the 3-bit TRP indication signaling domain is 011, the terminal equipment can determine that target TRPs corresponding to the pre-indication a in the serving cell a are TRP 1 and TRP 2;

if the domain value of the 3-bit TRP indication signaling domain is 111, the terminal device may determine that the target TRP corresponding to the pre-indication a in the serving cell a is TRP 0, TRP 1, and TRP 2.

The types of the first service data and the second service data are different, and the specific types of the first service data and the second service data are not limited in the present disclosure. In the following description, the first service data is eMBB service data, and the second service data is URLLC service data.

In one possible implementation manner, the method further includes: aiming at a communication link corresponding to the target TRP, receiving first service data on other time-frequency resources except the time-frequency resources indicated by the preemption indication information; and decoding the first service data.

For example, for a probe comprising 3 TRPs: a serving cell N of TRP 0, TRP 1, and TRP 2, where the terminal device determines, according to the received DCI, that preemption indication information corresponding to the serving cell N is pre-preemption indication N, and target TRPs corresponding to the pre-preemption indication N are TRP 1 and TRP 2, that is, the terminal device determines that, in a communication link corresponding to TRP 1 and TRP 2, there is a condition that a part of time-frequency resources for preempting eMBB service data transmission are present to transmit URLLC service data, then:

in a communication link corresponding to the TRP 1, the terminal device receives the eMBB service data on other time-frequency resources except the time-frequency resource indicated by the pre-indication N, and decodes the received eMBB service data, that is, in the decoding process, the terminal device may consider that the eMBB service data is not received on the time-frequency resource indicated by the pre-indication N;

in a communication link corresponding to the TRP 2, the terminal device receives the eMBB service data on other time-frequency resources except the time-frequency resource indicated by the pre-indication N, and decodes the received eMBB service data, that is, in the decoding process, the terminal device may consider that the eMBB service data is not received on the time-frequency resource indicated by the pre-indication N.

The eMBB service data received in different communication links may be the same or different, and this disclosure does not specifically limit this.

By determining the target TRP corresponding to the preemption indication information in the plurality of TRPs of the serving cell, the terminal equipment can accurately decode in a communication link corresponding to the target TRP which occupies part of the time-frequency resources for transmitting the first service data, thereby effectively improving the decoding performance of the terminal equipment.

In the communication link corresponding to the target TRP corresponding to the preemption indication information in the serving cell, part of time-frequency resources for preemptively transmitting the first service data can be realized to transmit the second service data, and in the communication links corresponding to other TRPs except the target TRP, the first service data is normally transmitted, so that the communication links corresponding to different TRPs can transmit different service data, and the performance requirements of each service can be ensured.

The method is applied to the network side device, for example, the network side device may be a base station of 5G and later versions (e.g., a gNB, a 5G NR NB), or a base station in other communication systems, or referred to as a node B, and the disclosure does not specifically limit the type of the network side device.

In one possible implementation, the DCI may be DCI format 2_ 1.

For each serving cell, when the serving cell includes multiple TRPs, the network side device may add, in the DCI sent to the terminal device, a TRP indication corresponding to the serving cell to indicate a target TRP corresponding to the preemption indication information in the multiple TRPs of the serving cell, that is, determine that there is a target TRP that preempts a part of time-frequency resources of the first service data, and then accurately decode in a communication link corresponding to the target TRP, thereby effectively improving the decoding performance of the terminal device.
