Technical field

This application relates to the field of communication, and more specifically, to a method and communication device for processing data.

Background technique

When at least two downlink data are carried on the same carrier, when the terminal device decodes the received at least two downlink data, if the resource block occupied by the downlink data #1 carried on the time domain resource #1 is , When the number of RBs is greater than a certain threshold, the terminal equipment's decoding processing of downlink data #1 may affect the decoding of downlink data #2 carried on time domain resource #2, where time domain resource #2 is later than Time domain resource #1, for example, the processing time delay of the terminal device on the downlink data #1 will increase the time delay of the terminal device's decoding processing on the downlink data #2.

At present, a solution is: when the above situation exists, the terminal device will usually give up decoding the downlink data #1, which is obviously not conducive to the normal communication between the network device and the terminal device, especially in multiple cooperative transmissions.

Summary of the invention

The present application provides a method for processing data, which can improve the flexibility of the network device in scheduling downlink data without increasing the complexity of the decoding processing of the terminal device.

In the first aspect, a method for processing data is provided, which includes: a terminal device (or a module in the terminal device, such as a chip) receiving first downlink data and second downlink data on a target carrier, where the bearer The end symbol of the time domain resource of the first downlink data is located before the start symbol of the time domain resource of the second downlink data, and the resource block (resource block, RB) that carries the first downlink data When the target condition is satisfied, skip the decoding process of the first downlink data; or, when the target condition is not satisfied, perform the decoding process on the first downlink data; wherein, The target condition is: the control channel resource set (CORESET) carrying the first (downlink control information, DCI) is the same as the CORESET carrying the second DCI, or the CORESET group carrying the first DCI is the same as the CORESET carrying the second DCI The CORESET group is the same, the first DCI is used to schedule the first downlink data, and the second DCI is used to schedule the second downlink data.

In other words, when the above target conditions are met, the terminal device skips the decoding processing of the first downlink data, which can be further interpreted as: when the control channel resource set CORESET carrying the first DCI is the same as the CORESET carrying the second DCI, Or, when the CORESET group carrying the first DCI is the same as the CORESET group carrying the second DCI, the terminal device skips the decoding process of the first downlink data, that is, the terminal device does not perform the decoding process on the first downlink data.

When the above target condition is not met, the terminal device performs decoding processing on the first downlink data, which can be further interpreted as: when the control channel resource set CORESET carrying the first DCI is different from the CORESET carrying the second DCI, or when the second DCI is carried When the CORESET group of one DCI is different from the CORESET group carrying the second DCI, the terminal device performs decoding processing on the first downlink data, that is, the terminal device performs decoding processing on the first downlink data and the second downlink data.

Based on the above technical solution, when the terminal device receives at least two downlink data on the same carrier, the terminal device is configured to determine whether the control channel resource set CORESET carrying the first DCI and the CORESET carrying the second DCI meet the target conditions, or, Determine whether to skip the decoding process of the first downlink data according to whether the CORESET group carrying the first DCI and the CORESET group carrying the second DCI meet the target condition, compared to skipping the decoding process of the first downlink data directly This solution can improve the flexibility of network equipment scheduling downlink data without increasing the complexity of the decoding processing of the terminal equipment.

It should be understood that, in a specific implementation, the aforementioned target carrier may include one carrier, that is, the first downlink data and the second downlink data are carried on one carrier, or the target carrier may include at least two carriers, that is, the first downlink The data and the second downlink data may be carried on different carriers respectively.

It should also be understood that, during specific implementation, the network device can send two or more downlink data including downlink data #1 and downlink data #2 to the terminal device on the target carrier, and this embodiment of the application does not do this. Specially limited.

It should also be understood that in specific implementation, the first downlink data and the second downlink data may respectively occupy continuous time units, such as continuous symbols, or may respectively occupy discontinuous time units. For example, when the first downlink data occupies a discontinuous time unit, one possible transmission method is that the first downlink data occupies multiple time slots (slots), but only some symbols are occupied in each slot, then The end symbol of the time domain resource carrying the first downlink data refers to the last symbol of the time domain resource carrying the first downlink data.

It should also be understood that, in a specific implementation, the time domain resources that carry the first downlink data and the time domain resources that carry the second downlink data may not overlap at all, or may partially overlap. This embodiment of the present application does not make any special difference. limited.

For example, the time domain resources that carry the first downlink data and the time domain resources that carry the second downlink data do not overlap at all can be interpreted as: the end symbol of the time domain resource of the first downlink data is located in the time domain resource of the second downlink data Before the start symbol of the first downlink data; the time domain resources that carry the first downlink data and the time domain resources that carry the second downlink data partially overlap can be interpreted as: the end symbol of the time domain resources that carry the first downlink data is located in the bearer After the start symbol of the time domain resource of the second downlink data and the start symbol of the time domain resource carrying the first downlink data is located before the end symbol of the time domain resource carrying the second downlink data, or, The end symbol of the time domain resource that carries the first downlink data is located after the end symbol of the time domain resource that carries the second downlink data, and the start symbol of the time domain resource that carries the first downlink data is located in the bearer Before the end symbol of the time domain resource of the second downlink data.

For scenarios where the first downlink data and the second downlink data partially overlap, this application provides a method for processing data, including: a terminal device (or a module in the terminal device, such as a chip) receiving on the target carrier The first downlink data and the second downlink data, wherein the number of resource blocks RBs carrying the first downlink data is greater than a preset value; when the target condition is met, the decoding process of the first downlink data is skipped Or, when the target condition is not satisfied, perform decoding processing on the first downlink data; wherein, the target condition is: the control channel resource set CORESET carrying the first DCI is the same as the CORESET carrying the second DCI, or The CORESET group carrying the first DCI is the same as the CORESET group carrying the second DCI. The first DCI is used to schedule the first downlink data, and the second DCI is used to schedule the second downlink data.

Optionally, the above-mentioned target condition may be replaced with the first DCI indicating that the demodulation reference signal (demodulation reference signal, DMRS) and the DMRS indicated by the second DCI belong to the same code division multiplexing (CDM) group.

Optionally, the foregoing target condition may be replaced with that the PUCCH resource indicated by the first DCI and the PUCCH resource indicated by the second DCI belong to the same PUCCH resource group.

Optionally, the above target condition can be replaced with the hybrid automatic repeat reQuest (HARQ) processing process number group indicated by the first DCI and the HARQ processing process number group indicated by the second DCI belong to the same HARQ processing process number group.

It should also be understood that the number of RBs carrying downlink data #1 above the preset value is only for illustrative purposes, and does not limit the embodiment of the present application. In specific implementation, it can also be replaced by the number of REs carrying downlink data #1. It is greater than the preset value, or it can be replaced by the bandwidth of the frequency domain resource carrying downlink data #1 being greater than the preset value, or it can be replaced by the number of RBs carrying the DMRS corresponding to downlink data #1 or the number of RBs carrying downlink data #1 The bandwidth of the frequency domain resource of the corresponding DMRS is greater than the preset value, which is not particularly limited in the embodiment of the present application.

In some implementation manners of the first aspect, the method further includes: when the target condition is satisfied, sending non-acknowledged NACK information of the first downlink data to the network device.

Based on the above technical solution, when the terminal device skips the decoding process of the first downlink data, by sending the non-acknowledged NACK information of the first downlink data to the network device, the terminal device may not decode the first downlink data. Instead, the network device is directly notified of the failure to decode the first downlink data.

That is to say, the terminal device needs to feed back the valid HARQ-ACK information of the first downlink data based on the success of the decoding process of the first downlink data, where the valid HARQ-ACK information includes acknowledged ACK information or non-acknowledged NACK information.

Based on the above technical solution, when the terminal device performs the decoding process of the first downlink data, the terminal device decodes the first downlink data by sending the acknowledgement ACK information or non-acknowledgement NACK information of the first downlink data to the network device. The situation of success or failure of decoding informs the network equipment.

Wherein, the number of first carriers is greater than or equal to 2.

Specifically, the network device may configure the target carrier according to the number of first carriers. For example, when the number of carriers configured by the network device is equal to the number of first carriers, it means that the network device has not configured any carrier as the target carrier, and it means that none of the terminal devices on the carrier configured by the network device supports the first processing capability.

For another example, when the number of carriers configured by the network device is less than or equal to half of the first carrier number, carriers configured by the network device that are less than or equal to half of the first carrier number are all target carriers, and it represents that the carrier configured by the network device is less than or equal to half of the first carrier number.

Optionally, each carrier configured by the network device carries indication information, and the indication information is used to indicate whether each carrier supports the terminal device to receive data using the first processing capability. Wherein, the indication information may be CORESET group indication information. For example, if only one CORESET group is configured on carrier 1, it indicates that carrier 1 does not support receiving data with the first processing capability. For another example, if two CORESET groups are configured on carrier 2, it indicates that carrier 2 supports receiving with the first processing capability. data.

In this case, Each carrier configured by the network device needs to carry this indication information.

The first DCI is used to schedule the first downlink data, and the second DCI is used to schedule the second Downlink data.

In some implementations of the second aspect, the method further includes: receiving processing capability information from the terminal device, the processing capability information indicating that the terminal device has a first processing capability, and the terminal device has a first processing capability. A processing capability indicates that the terminal device can receive at least two downlink data simultaneously in the same carrier; the target carrier is configured according to the processing capability information.

In some implementation manners of the second aspect, the processing capability information carries a first carrier quantity, and the first carrier quantity represents that the terminal device supports the network device to configure a target carrier for the terminal device. Wherein, the number of first carriers is greater than or equal to 2.

Specifically, the network device may determine whether to configure the target carrier for the terminal device and the configured target carrier number according to the first carrier quantity. For example, when the number of carriers configured by the network device is equal to the number of first carriers, it means that the network device has not configured any carrier as the target carrier, and it means that none of the terminal devices on the carrier configured by the network device supports the first processing capability.

For example, when the number of carriers configured by the network device is less than or equal to half of the first carrier number, the carriers configured by the network device less than or equal to half of the first carrier number are all target carriers, and it represents that the number of carriers configured by the network device is less than or equal to All terminal devices on carriers equal to half of the number of the first carriers support the first processing capability.

For example, when the number of carriers configured by the network device is greater than half of the number of the first carrier and less than the number of the first carrier, it means that part of the carrier configured by the network device is the target carrier, and the other part is not the target carrier. In this case, the network device can Configuring carriers less than or equal to half of the number of the first carriers as the target carrier means that the terminal device supports the first processing capability on the target carrier, and the terminal device does not support the first processing capability on the other part of the non-target carriers.

That is to say, the terminal device needs to feed back the valid HARQ-ACK information of the first downlink data based on the success of the decoding process of the first downlink data, where the valid HARQ-ACK information includes acknowledged ACK information or non-acknowledged NACK information.

Based on the above technical solution, when the terminal device performs the decoding process of the first downlink data, the terminal device decodes the first downlink data by sending the acknowledgement ACK information or non-acknowledgement NACK information of the first downlink data to the network device. The success or failure of decoding informs the network equipment.

The first DCI is used to schedule the first downlink data, and the second DCI is used to schedule the second downlink data.

For example, the network device sends the first downlink data and the second downlink data to the terminal device, where the terminal device supports performing data processing operations at the second time interval.

In the following, for ease of understanding, the basic flow of data transmission and multi-TRP transmission involved in the embodiments of the present application are introduced.

1. The basic process of data transmission

1. scrambling

The current protocol supports the transmission of up to two codewords. Each codeword q corresponds to a set of bits

This group of bits can be considered as a transmission block (TB). among them,

Is the number of bits of the codeword q transmitted in the physical channel, and the scrambled codeword is obtained through the following operations

Among them, c ^(q) (i) is the scrambling sequence:

2. Modulation

For each codeword q, the scrambled codeword will use one of the modulation methods in Table 1 to obtain a group of complex-valued modulation symbols

Table 1 Modulation method

调制方式Modulation	调制阶数 Modulation order

QPSKQPSK	22
16QAM16QAM	44
64QAM64QAM	66
256QAM256QAM	88

Among them, QPSK means quadrature phase shift keying (quadrature phase shift keying, QPSK), and QAM means quadrature amplitude modulation (quadrature amplitude modulation, QAM).

3. Layer mapping and antenna port mapping

The complex-valued modulation symbols after modulation are mapped to one or more layers according to Table 2. Modulation symbol for each codeword q

Is mapped to the layer x(i)=[x ⁽⁰⁾ (i) ... x ^(υ-1) (i)] ^T ,

Where v is the number of transmission layers,

Is the number of modulation symbols per layer. The data of each layer relies on spatial multiplexing. The vector x(i)=[x ⁽⁰⁾ (i) ... x ^(υ-1) (i)] ^T is mapped to the antenna port according to the following formula:

among them,

For a UE, NR supports a maximum of 8 layers of downlink data transmission at this stage, where each codeword supports a maximum of 4 layers of downlink transmission, and each codeword corresponds to its own independent modulation and coding scheme (modulation and coding scheme, MCS), the downlink control information (downlink control information, DCI) contains the MCS field corresponding to each codeword, and this field indicates the modulation mode, target code rate, and spectral efficiency information.

Table 2 Codeword to layer mapping

4. Physical resource mapping

It is mapped to a resource element (RE) of a physical resource block (resource block, RB). Generally, a demodulation reference signal (DMRS) corresponding to the data is also sent before the data is sent for channel estimation of the data to complete correct demodulation.

2. Multi TRP transmission

In downlink transmission, a terminal device can communicate with at least one base station at the same time, that is, receive data from multiple base stations at the same time. This transmission mode is called coordinated multiple points transmission/reception (CoMP). The aforementioned at least one base station forms a cooperating set to communicate with the terminal device at the same time. The base stations in the cooperating set can each connect to different control nodes, and each control node can exchange information, such as exchanging scheduling policy information to achieve the purpose of cooperative transmission. Or, the base stations in the cooperating set are all connected to the same control node, and the control node receives the channel state information (for example, channel state information (CSI) or reference signal reception) reported by the terminal equipment collected by the base stations in the cooperating set Power (reference signal receiving power, RSRP), and perform unified scheduling on the terminal devices in the cooperating set according to the CSI of all terminal devices in the cooperating set, and then exchange the scheduling strategy to the base station connected to it, and then each base station carries the load through the PDCCH DCI signaling informs respective terminal devices.

According to the information exchange delay between base stations, CoMP transmission can be divided into ideal backhaul (IB) and non-ideal backhaul (NIB). In the NIB scenario, due to the long distance between the base stations or the copper wire connection between the base stations, the interaction delay is 2-5ms, and may even reach 30ms. At this time, if the framework of controlling multiple cooperative base stations by the central control node is still adopted, the scheduling information will become invalid due to the interaction delay, which will affect the performance of the entire system. Therefore, in this scenario, multiple cooperative base stations are supported to independently issue DCI to independently schedule the PDSCH of the UE. At this time, it is necessary to support each coordinated base station to independently indicate DCI, and multiple coordinated base stations will determine how to schedule the terminal device according to their own scheduling policies and algorithms. When multiple coordinated base stations schedule the terminal device at the same time according to their respective scheduling decisions, the terminal device will receive multiple DCIs at the same time to schedule their respective PDSCHs. In this scenario, the PDSCH scheduled by each TRP also supports independent hybrid automatic repeat request (HARQ) feedback. For example, TRP#1 schedules PDSCH#1 through DCI#1, and TRP#2 passes DCI. #2 schedules PDSCH#2, then the acknowledgement #1 (ACK)/non-acknowledgement #1 (NACK) feedback of PDSCH#1 is carried on PUCCH#1, TRP#1 will receive PDSCH#1 feedback on this resource, PDSCH #2's ACK#2/NACK#2 feedback is carried on PUCCH#2, TRP#2 will receive PDSCH#2 feedback on this resource, as shown in Figure 2.

In the IB scenario, the interaction delay between two base stations can be considered negligible, so from the perspective of the terminal device, it cannot clearly distinguish whether the received data comes from one base station or two base stations, that is, a single base station From the perspective of terminal equipment, there is not much difference between the working mode and the working mode of multiple base stations. At this time, the data sent by the two base stations can be sent by one base station or two DCI scheduling by two base stations respectively. The PDSCH sent by the two base stations can be fed back on one PUCCH resource, that is, two PDSCHs correspond to The HARQ bits can be jointly coded to form a group of UCI bits, as shown in Figure 3.

Above, the technical terms involved in the embodiments of the present application are briefly described. Hereinafter, the method of processing data in the embodiment of the present application will be described in detail.

At present, a solution is: when the above situation exists, the terminal device usually abandons the decoding processing of the downlink data #1 in order to ensure the normal processing of the downlink data #2, which is obviously not conducive to the communication between the network device and the terminal device. Normal communication, especially when multiple coordinated transmission nodes jointly serve the same terminal device and the information interaction between the multiple transmission nodes adopts time-delayed interaction. For example, two transmission nodes cannot obtain the scheduling information of each other in real time, This will cause one of the downlink data to be skipped for decoding in the above scenario.

Therefore, the embodiments of the present application provide a data processing method, which can increase the flexibility of network equipment scheduling data without increasing the decoding processing complexity of the terminal equipment, thereby enabling multiple transmissions to be supported in non-ideal interactive scenarios. It is possible for each node to schedule data for the same terminal device.

Hereinafter, the method for processing data provided by the embodiment of the present application will be described in detail with reference to FIGS. 4 to 6.

FIG. 4 is a schematic interaction diagram of a method 200 for processing data provided by an embodiment of the present application. Hereinafter, each step of the method 200 will be described in detail.

In the embodiment of the present application, the method 200 will be described by taking a terminal device and a network device as an executor of the method 200 as an example. As an example and not a limitation, the execution subject of the method 200 may also be a chip corresponding to a terminal device and a chip corresponding to a network device.

In S210, the network device sends downlink data #1 (that is, an example of the first downlink data) and downlink data #2 (that is, an example of the second downlink data) on the target carrier. The end symbol of the time domain resource is located before the start symbol of the time domain resource carrying downlink data #2, and the number of RBs carrying downlink data #1 is greater than a preset value (for example, the preset value may be 136 RB), where the bearer The control channel resource set CORESET of DCI#1 (i.e., an example of the first DCI) is different from the CORESET carrying DCI#2 (i.e., an example of the second DCI), or the CORESET group carrying DCI#1 and the CORESET group carrying DCI#2 The CORESET group is different, DCI#1 is used to schedule downlink data #1, and DCI#2 is used to schedule downlink data #2. Correspondingly, the terminal device receives downlink data #1 and downlink data #2 from the network device.

It should be understood that, in a specific implementation, the aforementioned target carrier may include one carrier, that is, downlink data #1 and downlink data #2 are carried on one carrier, or the target carrier may include at least two carriers, that is, downlink data #1 and Downlink data #2 can be carried on different carriers respectively.

It should also be understood that in specific implementation, the downlink data #1 and the downlink data #2 may occupy continuous time units, such as continuous symbols, or may occupy discontinuous time units. For example, when downlink data #1 occupies a discontinuous time unit, a possible transmission method is that downlink data #1 occupies multiple slots, but only some symbols are occupied in each slot, then the downlink data #1 is carried. The end symbol of the time domain resource refers to the last symbol of the time domain resource carrying downlink data #1; another possible transmission method is that downlink data #1 occupies multiple symbol groups in a slot, and each symbol group includes There are multiple consecutive symbols, and there is a time interval between different symbol groups.

It should also be understood that, in specific implementation, the time domain resources carrying downlink data #1 and the time domain resources carrying downlink data #2 may not overlap at all, or may partially overlap, which is not particularly limited in the embodiment of the application. .

For example, the time domain resources that carry downlink data #1 and the time domain resources that carry downlink data #2 do not overlap at all can be interpreted as: the end symbol of the time domain resource of downlink data #1 is located at the beginning of the time domain resource of downlink data #2 Before the start symbol; the partial overlap of the time domain resource carrying downlink data #1 and the time domain resource carrying downlink data #2 can be interpreted as: the end symbol of the time domain resource carrying the downlink data #1 is located in the carrying the downlink data # After the start symbol of the time domain resource of 2 and the start symbol of the time domain resource carrying the downlink data #1 is located before the end symbol of the time domain resource carrying the downlink data #2, or carrying the downlink data The end symbol of the time domain resource #1 is located after the end symbol of the time domain resource that carries the downlink data #2, and the start symbol of the time domain resource that carries the downlink data #1 is located in the time domain resource that carries the downlink data #2. Before the end symbol of the time domain resource.

When downlink data #1 and downlink data #2 partially overlap, the above S210 can be replaced with: the network device sends downlink data #1 and downlink data #2 on the target carrier, where the number of RBs carrying downlink data #1 is greater than the preset Value, the control channel resource set CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or the CORESET group carrying DCI#1 is different from the CORESET group carrying DCI#2, and DCI#1 is used to schedule downlink data #1 , DCI#2 is used to schedule downlink data #2. Correspondingly, the terminal device receives downlink data #1 and downlink data #2 from the network device.

In S220, when the target condition #1 is satisfied (that is, an example of the target condition), the terminal device skips the decoding process of the downlink data #1; or, when the target condition #1 is not satisfied, the terminal device performs the downlink data # 1 Perform decoding processing.

The above target condition #1 may be: the control channel resource set CORESET carrying DCI#1 is the same as the CORESET carrying DCI#2, or the CORESET group carrying DCI#1 is the same as the CORESET group carrying DCI#2, and DCI#1 is used For scheduling downlink data #1, DCI #2 is used for scheduling downlink data #2.

Specifically, the terminal device receives downlink data #1 and downlink data #2 from the network device, the terminal device can determine whether the target condition #1 is satisfied, and when the target condition #1 is satisfied, the terminal device skips the download of the downlink data #1 Decoding processing; or, when target condition #1 is not met, the terminal device performs decoding processing on downlink data #1. For example, if the terminal device determines that the CORESET carrying DCI#1 is the same as the CORESET carrying DCI#2, the terminal device determines that the target condition #1 is satisfied, and then skips the decoding process of the downlink data #1; or, the terminal device determines that the DCI# is carried. The CORESET of 1 is different from the CORESET that carries DCI#2, and the terminal device determines that the target condition #1 is not satisfied, and then performs decoding processing on the downlink data #1.

In other words, when the above target condition #1 is met, the terminal device skips the decoding process of downlink data #1, which can be further interpreted as: when the control channel resource set CORESET carrying DCI#1 is the same as the CORESET carrying DCI#2 Or, when the CORESET group carrying DCI#1 is the same as the CORESET group carrying DCI#2, the terminal device will skip the decoding process of downlink data #1, that is, the terminal device will not perform decoding processing on downlink data #1.

When the above target condition #1 is not met, the terminal device performs decoding processing on downlink data #1, which can be further interpreted as: when the control channel resource set CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or when the carrier When the CORESET group of DCI#1 is different from the CORESET group carrying DCI#2, the terminal device performs decoding processing on downlink data #1, that is, the terminal device performs decoding processing on downlink data #1 and downlink data 2.

It should be noted that in specific implementation, the above S220 can also be replaced with:

When the target condition #2 is satisfied (ie, another example of the target condition), the terminal device performs decoding processing on the downlink data #1; or, when the target condition #2 is not satisfied, the terminal device skips the decoding of the downlink data #1 deal with.

The above target condition #2 can be: the control channel resource set CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or the CORESET group carrying DCI#1 is different from the CORESET group carrying DCI#2, and DCI#1 is used For scheduling downlink data #1, DCI #2 is used for scheduling downlink data #2.

In other words, when the above target condition #2 is satisfied, the terminal device performs decoding processing on downlink data #1, which can be further interpreted as: when the control channel resource set CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or When the CORESET group carrying DCI#1 is different from the CORESET group carrying DCI#2, the terminal device performs decoding processing on downlink data #1, that is, the terminal device performs decoding processing on downlink data #1 and downlink data 2.

When the above target condition #2 is not met, the terminal device skips the decoding process for downlink data #1, which can be further interpreted as: when the control channel resource set CORESET carrying DCI#1 is the same as the CORESET carrying DCI#2, or, When the CORESET group carrying DCI#1 is the same as the CORESET group carrying DCI#2, the terminal device skips the decoding process of downlink data #1, that is, the terminal device does not perform decoding processing on downlink data #1.

The terminal device can determine whether the CORESET group carrying DCI#1 is the same as the CORESET group carrying DCI#2 according to the configuration information of CORESET. For example, CORESET grouping information may be included in the configuration information of each CORESET, and each CORESET configuration information includes an index value. CORESET configured with the same index value belong to the same CORESET group, and CORESET configured with different index values belong to different CORESET groups.

The terminal device can determine that the current DCI is DCI#1 or DCI#2 by detecting the CORESET to which the DCI belongs. For example, when the CORESET to which the detected DCI belongs belongs to CORESET group 1, the DCI is DCI#1, and when the CORESET to which the detected DCI belongs belongs to CORESET group 2, the DCI is DCI#2.

It should be noted that when the control channel resource set CORESET carrying DCI#1 is the same as the CORESET carrying DCI#2, or when the CORESET group carrying DCI#1 is the same as the CORESET group carrying DCI#2, it can represent the downlink Data #1 and downlink data #2 come from the same TRP; when the control channel resource set CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or when the CORESET group carrying DCI#1 is the same as the CORESET carrying DCI#2 When the CORESET group is different, it can represent that the downlink data #1 and the downlink data #2 are from different TRPs.

Therefore, when the terminal device receives at least two downlink data on the same carrier, the terminal device can determine whether the CORESET bearing DCI#1 and the CORESET bearing DCI#2 meet the target conditions, or according to the CORESET bearing DCI#1 Whether the group and the CORESET group carrying DCI#2 meet the target conditions, determine whether to skip the decoding process of the first downlink data. Compared with skipping the decoding process of the first downlink data directly, this solution can not increase Under the premise of the complexity of the decoding processing of the terminal equipment, the flexibility of the network equipment in scheduling downlink data is improved.

When the network device sends at least two downlink data to the terminal device on the same carrier, in order to obtain valid HARQ-ACK feedback information, the downlink data #1 and the downlink data #2 can be scheduled by different CORESET or DCI in the CORESET group, This solution can improve the flexibility of network equipment scheduling downlink data without increasing the complexity of the decoding processing of the terminal equipment.

In addition, the terminal device can also determine whether to perform decoding processing on downlink data #1 in the following ways:

Way #1

Way #2

The terminal device may determine whether to perform decoding processing on downlink data #1 according to whether the time domain resource carrying downlink data #1 and the time domain resource carrying downlink data #2 belong to the same time domain resource set.

When the index of the time domain resource carrying downlink data #1 is the same as the index of the time domain resource carrying downlink data #2, it means that the time domain resource carrying downlink data #1 and the time domain resource carrying downlink data #2 belong to the same time.

When the start symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying downlink data #2 are located in the same sub-slot, or when the time domain resource carrying downlink data #1 When the start symbol and the start symbol of the time domain resource carrying downlink data #2 are in the same sub-slot set, the terminal device skips the decoding process of downlink data #1; when the time domain resource carrying downlink data #1 is When the start symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying downlink data #2 are located in different sub-slots, or when the start symbol of the time domain resource carrying downlink data #1 is different from the start symbol of the time domain resource carrying downlink data #2 When the start symbol of the domain resource is located in different sub-slot sets, the terminal device performs decoding processing on downlink data #1.

It should be noted that when the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying downlink data #2 are located in the same sub-slot, or when the time domain resource carrying downlink data #1 When the time domain resource that carries downlink data #2 is in the same sub-slot set, it can represent that downlink data #1 and downlink data #2 come from the same TRP; when the time domain resource that carries downlink data #1 and the downlink data are carried When the start symbol of the time domain resource #2 is located in different sub-slots, or when the time domain resource carrying downlink data #1 and the time domain resource carrying downlink data #2 are located in different sub-slot sets, It means that downlink data #1 and downlink data #2 are from different TRPs.

It should also be noted that when the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying downlink data #2 are located in the same sub-slot, or when carrying downlink data #1 When the domain resource and the time domain resource carrying the downlink data #2 are located in the same sub-slot set, it means that the downlink data #1 and the downlink data #2 are from the same TRP, which is only for illustrative purposes and does not limit the embodiment of the application. . In specific implementation, the sub-slot can also be replaced with a time slot or a time unit, and the start symbol can also be replaced with an end symbol or with a start symbol and an end symbol.

In addition, the terminal device may determine whether to perform decoding processing on downlink data #1 according to whether DMRS#1 indicated by DCI#1 and DMRS#2 indicated by DCI#2 belong to the same CDM group. For example, the terminal device can parse DCI#1 and DCI#2 separately, parse DCI#1 to obtain the index of the CDM group of DMRS#1 indicated by DCI#1, and parse DCI#2 to obtain the DMRS#2 indicated by DCI#2. The index of the CDM group may further determine whether DMRS#1 indicated by DCI#1 and DMRS#2 indicated by DCI#2 belong to the same CDM group according to the determined index of the CDM group.

When the CDM group to which DMRS#1 indicated by DCI#1 belongs and the CDM group to which DMRS#2 indicated by DCI#2 belongs belong to the same CDM group, the terminal device skips the decoding process of downlink data #1; when the DMRS indicated by DCI#1 When the CDM group to which #1 belongs and the CDM group to which DMRS#2 indicated by DCI#2 belongs belong to different CDM groups, the terminal device performs decoding processing on the downlink data #1.

In addition, the terminal device may also determine whether to perform decoding processing on downlink data #1 according to whether the HARQ processing process number group indicated by DCI#1 and the HARQ processing process number group indicated by DCI#2 belong to the same HARQ processing process number group.

For example, the terminal device can parse DCI#1 and DCI#2 separately, parse DCI#1 to obtain the index of the HARQ processing process number group indicated by DCI#1, and parse DCI#2 to obtain the HARQ processing process number group indicated by DCI#2 According to the index of the determined HARQ processing process number group, it can be determined whether the HARQ processing process number group indicated by DCI#1 and the HARQ processing process number group indicated by DCI#2 belong to the same HARQ processing process number group.

When the HARQ processing process number group indicated by DCI#1 and the HARQ processing process number group indicated by DCI#2 belong to the same HARQ processing process number group, the terminal device skips the decoding process of downlink data #1; when DCI#1 indicates When the HARQ processing process number group and the HARQ processing process number group indicated by DCI#2 belong to different HARQ processing process number groups, the terminal device performs decoding processing on the downlink data #1.

When the terminal device performs decoding processing on the downlink data #1, the method 200 may further include: S230: The terminal device sends the ACK information or NACK information of the downlink data #1 to the network device. Correspondingly, the network device receives ACK information or NACK information of downlink data #1 from the terminal device.

In other words, when the terminal device performs decoding processing on the downlink data #1, the terminal device may decode the downlink data #1 successfully or fail. When the terminal device decodes the downlink data #1 successfully, the terminal device can send the ACK information of the downlink data #1 to the network device; or, when the terminal device fails to decode the downlink data #1, the terminal device can send the downlink data to the network device #1’s NACK information.

When the terminal device skips the decoding process of the downlink data #1, S230 can also be replaced with: the terminal device sends the NACK information of the downlink data #1 to the network device. Correspondingly, the network device receives the NACK information of downlink data #1 from the terminal device.

In other words, when the terminal device skips the decoding process of the downlink data #1, by sending the unacknowledged NACK information of the downlink data #1 to the network device, the terminal device can directly transmit the downlink data #1 without decoding the downlink data #1. The information of data #1 decoding failure is notified to the network equipment.

For downlink data #1, the minimum time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying the feedback information of downlink data #1 is defined as time interval #1 (ie , An example of the first time interval), for downlink data #2, the minimum time between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying feedback information of downlink data #2 The interval is defined as time interval #2 (ie, an example of the second time interval), then the time interval #1 may be greater than the time interval #2.

Time interval #1 and time interval #2 can be pre-defined. The terminal device does not need to report time interval #1 to the network device. The network device will default to the terminal device supporting time interval #1 to perform data processing operations, thus changing the time interval # 1 As the minimum time interval to schedule downlink data #1; for time interval #2, the terminal device needs to report to the network device that it supports the use of time interval #2 to perform data processing operations, and then the network device will take the time interval #2 as the minimum Time interval to schedule downlink data #2.

Said time interval # 1 can carry downlink data end symbol time domain resource # 1 to # bearer downlink data minimum number of symbols between symbols in the time domain resource initial feedback information to determine 1 N _1, N ₁ taken The value can be as shown in Table 3, for example.

table 3

The aforementioned time interval #2 can be determined according to the minimum number of symbols N1 between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2. The value of N1 is for example It can be as shown in Table 4.

Table 4

The terminal device in method 200 may have processing capability #1 (that is, an example of the first processing capability), and the terminal device has processing capability #1, which means that the terminal device is capable of processing two downlink data or multiple downlink data simultaneously in the same carrier. Data capabilities.

When the terminal device has processing capability #1 and supports the use of time interval #2 to perform data processing operations, the network device can simultaneously send downlink data #1 and downlink data #2 to the terminal device within the same carrier, and the network device schedules downlink data #1 The minimum scheduling delay with downlink data #2 is both time interval #2. At this time, the terminal device can use the time interval #2 as the minimum time interval to perform data processing operations on the downlink data #1 and the downlink data #2 respectively.

When the terminal device has processing capability #1 and does not support the use of time interval #2 to perform data processing operations, the network device can simultaneously send downlink data #1 and downlink data #2 to the terminal device within the same carrier, and the network device schedules downlink data# The minimum scheduling delays of 1 and downlink data #2 are both time interval #1. At this time, the terminal device can use the time interval #1 as the minimum time interval to perform data processing operations on the downlink data #1 and the downlink data #2 respectively.

The terminal device may report its own processing capability #1 to the network device, so that the network device can configure the target carrier in S210 according to the processing capability of the terminal device. At this time, the method 200 may further include:

The terminal device sends processing capability information to the network device, and the processing capability information indicates that the terminal device has processing capability #1. Correspondingly, the network device receives the processing capability information from the terminal device.

The network device configures the target carrier according to the processing capability information.

In an implementation manner, the processing capability information may include the number of carriers #1 (ie, an example of the first number of carriers), and the number of carriers #1 is used to indicate that the terminal device supports the network device to configure the target carrier for the terminal device. Wherein, the number of carriers #1 is greater than or equal to 2.

Specifically, the network device may determine whether to configure the target carrier and the number of target carriers for the terminal device according to the number of carriers #1.

When the number of carriers configured by the network device is equal to the number of carriers #1, for example, the number of carriers #1 is 4, and the number of carriers configured by the network device is also 4, which means that the network device has not configured any carrier as the target carrier, and it represents None of the terminal devices on the carrier configured by the device supports processing capability #1.

When the number of carriers configured by the network equipment is less than or equal to half of the number of carriers #1, for example, the number of carriers #1 is 6, and the number of carriers configured by the network equipment is 3, which means that the number of carriers configured by the network equipment is less than or equal to half of the number of carriers #1 The carriers are all target carriers, and it means that the terminal equipment on the carriers configured by the network equipment less than or equal to half of the carrier number #1 all support the processing capability #1.

When the number of carriers configured by the network device is greater than half of the number of carriers #1 and less than the number of carriers #1, for example, the number of carriers #1 is 6, and the number of carriers configured by the network device is 5, which means that part of the carriers configured by the network device is The target carrier, the other part is not the target carrier. At this time, the network equipment can configure the carrier less than or equal to half of the carrier number #1 as the target carrier, which means that the terminal equipment supports processing capability #1 on the target carrier, and the other part is not The terminal device on the target carrier does not support processing capability #1. In another implementation manner, the processing capability information may include the number of carriers #2 (ie, an example of the second number of carriers), and the number of carriers #2 is used to represent the number of target carriers supported by the terminal device. When the network equipment configures the target carrier, it can configure the carrier that meets the number of carriers #2 as the target carrier.

For example, if the number of carriers #2 included in the processing capability information is 4, it means that the terminal device supports the network device to configure 4 carriers as the target carrier, that is, it supports the network device to schedule at least two carriers on each of the 4 carriers at the same time. Downlink data. The network device may configure one or more of these 4 carriers as the target carrier.

The above describes the method for the network device to configure the target carrier when the number of carriers #1 is greater than or equal to 2. In addition, when the terminal device reports that the number of carrier number #1 is 1, it indicates that the terminal device does not support configuring the target carrier. In other words, the carrier configured by the network device cannot support simultaneous transmission of multiple PDSCHs, or in other words, none of the terminal devices on the carrier configured by the network device supports processing capability #1.

In another implementation manner, the processing capability information may include the number of carriers #1 and the number of carriers #2. When configuring the target carrier, the network device may configure the target carrier according to the relationship between the number of carriers #1 and the number of carriers #2.

For example, if the number of carriers #1 included in the processing capability information is 7, and the number of carriers #2 is 7, it means that the terminal device does not support the network device to configure the carrier carrying the downlink data to be sent to the terminal device as the target carrier.

For example, if the number of carriers #1 included in the processing capability information is 6, and the number of carriers #2 is 3, it means that the terminal device supports the network device to configure all the carriers carrying the downlink data to be sent to the terminal device as the target carrier.

For example, if the number of carriers #1 included in the processing capability information is 8, and the number of carriers #2 is 5, it means that the terminal device supports the network device to configure part of the carriers carrying the downlink data to be sent to the terminal device as the target carrier.

Exemplarily, when configuring the target carrier, the network device may indicate to the terminal device the index configured as the target carrier. For example, if the network equipment indicates carrier #1, carrier #3, and carrier #7 to the terminal equipment, it means that the network equipment configures carrier #1, carrier #3, and carrier #7 as the target carrier, that is, when sending downlink data, the carrier #1, carrier #3, and carrier #7 simultaneously carry at least two downlink data.

The embodiment of the present application also provides another method for processing data, which is introduced below.

For a terminal device that supports data processing operations using time interval #2, when at least two downlink data are carried in one carrier, for example, downlink data #1 and downlink data #2 are carried in one carrier, where the downlink Data #1 comes before, and downlink data #2 comes after. For the downlink data (downlink data #1 and/or downlink data #2) occupied by the number of RBs greater than the preset value, the terminal device usually takes the time interval #1 as the minimum Time interval to perform data processing operations on the downlink data.

In order to enable the terminal equipment to process multiple PDSCHs at the same time, and to enable the supporting terminal equipment to use time interval #2 to perform data processing operations, when a carrier carries the downlink data #1 and downlink data #2 to be sent to the terminal equipment , You can redefine the preset value (for example, the first preset value) corresponding to the number of RBs carrying downlink data, where the first preset value is less than the preset value in method 200, so that the terminal device can use the time interval #2 Perform data processing on the downstream data.

Optionally, the preset value in the method 200 is 136 RB, or half of the system bandwidth.

Here, one way to understand that the terminal device can process multiple downlink data at the same time is: it can support the network device to schedule multiple downlink data at the same time and the feedback delay corresponding to the multiple downlink data does not increase, such as the minimum time interval for multiple downlink data Determine according to the minimum number of symbols in Table 3 or Table 4.

For example, the network device sends downlink data #1 and downlink data #2 to the terminal device, where the terminal device supports the use of time interval #2 to perform data processing operations.

When the number of RBs occupied by downlink data #1 is greater than the first preset value, and the number of RBs occupied by downlink data #2 is greater than the first preset value, the network device schedules the minimum scheduling delay for downlink data #1 and downlink data #2 All are time interval #1. That is, when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying the feedback information of downlink data #1 is not less than the time interval #1, the terminal device will Feedback the corresponding HARQ-ACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying the feedback information of downlink data #1 is less than time interval #1, Then the terminal device will feed back the corresponding NACK information; when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is not less than time interval #1 , The terminal device will feed back the corresponding HARQ-ACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is less than Time interval #1, the terminal device will feed back corresponding NACK information.

When the number of RBs occupied by downlink data #1 is less than the first preset value, and the number of RBs occupied by downlink data #2 is greater than the first preset value, the minimum scheduling delay for the network device to schedule downlink data #1 is time interval #2 , The minimum scheduling delay for the network device to schedule downlink data #2 is time interval #1. In other words, when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying feedback information of downlink data #1 is less than time interval #2, the terminal device will feedback Corresponding NACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying feedback information of downlink data #1 is not less than time interval #2, the terminal The device will feed back the corresponding HARQ-ACK information; when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is not less than time interval #1 , The terminal device will feed back the corresponding HARQ-ACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is less than Time interval #1, the terminal device will feed back corresponding NACK information.

When the number of RBs occupied by downlink data #1 is greater than the first preset value, and the number of RBs occupied by downlink data #2 is less than the first preset value, the minimum scheduling delay for the network device to schedule downlink data #1 is time interval #1 , The minimum scheduling delay for the network equipment to schedule downlink data #2 is time interval #2. That is, when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying the feedback information of downlink data #1 is less than the time interval #1, the terminal device will feedback Corresponding NACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #1 and the start symbol of the time domain resource carrying feedback information of downlink data #1 is not less than time interval #1, the terminal The device will feed back the corresponding HARQ-ACK information; when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is not less than time interval #2 , The terminal device will feed back the corresponding HARQ-ACK information, or when the time interval between the end symbol of the time domain resource carrying downlink data #2 and the start symbol of the time domain resource carrying the feedback information of downlink data #2 is less than Time interval #2, the terminal device will feed back corresponding NACK information.

In addition, the method 200 is also applicable to the scenario of redefining the preset value (for example, the first preset value) corresponding to the number of RBs carrying downlink data. In this case, S210 needs to be replaced with: the network device transmits on the target carrier Downlink data #1 and downlink data #2, where the end symbol of the time domain resource carrying downlink data #1 is located before the start symbol of the time domain resource carrying downlink data #2, and the number of RBs carrying downlink data #1 is greater than The first preset value, where the CORESET carrying DCI#1 is different from the CORESET carrying DCI#2, or the CORESET group carrying DCI#1 is different from the CORESET group carrying DCI#2, and DCI#1 is used for scheduling downlink data #1, DCI#2 is used to schedule downlink data #2. Correspondingly, the terminal device receives downlink data #1 and downlink data #2 from the network device.

The embodiments of the present application also define conditions for joint HARQ for a joint HARQ scenario under IB, and the conditions are described below.

When downlink data #1 and downlink data #2 are carried in the same time unit (for example, the same slot), the condition for allowing joint HARQ feedback at this time is: the network device uses time interval #1 as the minimum time interval to schedule downlink Data #1. At the same time, the terminal device uses the time interval #1 as the minimum time interval to perform the data processing operation of the downlink data #1, and the network device uses the time interval #2 as the minimum time interval to schedule the downlink data #2, and the terminal device sets the time Interval #2 is the minimum time interval to perform the data processing operation of downlink data #2.

When the network device uses time interval #1 as the minimum time interval to schedule one of the downlink data (for example, downlink data #2), and the terminal device uses time interval #1 as the minimum time interval to perform the data processing operation of the downlink data, this The condition for allowing joint HARQ feedback is that the number of RBs carrying another downlink data (for example, downlink data #1) is less than a preset value.

It should be noted that the downlink data in this application can be replaced with PDSCH.

FIG. 5 is a schematic interaction diagram of a method 300 for processing data provided by an embodiment of the present application. Hereinafter, each step of the method 300 will be described in detail.

In the embodiment of the present application, the method 300 is described by taking the terminal device and the network device as the execution subject of the method 300 as an example. As an example and not a limitation, the execution subject of the method 300 may also be a chip corresponding to a terminal device and a chip corresponding to a network device.

In S310, the terminal device sends first capability indication information, where the first capability indication information is used to indicate the number of first carriers supported by the terminal device. Correspondingly, the network device receives the first capability indication information from the terminal device.

In S320, the network device determines the number of second carriers according to the number of first carriers, where the number of second carriers is less than or equal to the number of first carriers, and the number of second carriers is A+Bⅹr, and the second carrier The minimum time interval between the end symbol of the time domain of the physical downlink shared channel PDSCH and the start symbol of the time domain carrying the feedback information of the PDSCH is less than the preset time interval threshold. A means that only one control resource set group information is configured or not The number of carriers configured with control resource group information, B is the number of carriers configured with multiple control resource group information, and r is a positive number greater than or equal to 1.

Among them, the aforementioned preset time interval threshold corresponds to the value of the minimum time interval shown in Table 4, that is, it supports the use of capability 2 to perform data processing operations.

Optionally, the activated BWP in the A carriers is configured with only one control resource set group information or no control resource set group information is configured.

Optionally, if the HARQ-ACK feedback corresponding to the PDSCH scheduled in the A carriers is in one slot, the HARQ-ACK feedback is all carried on the same PUCCH resource.

Optionally, the activated BWPs in the B carriers are configured with two or more control resource set group information.

Optionally, if the HARQ-ACK feedback corresponding to the PDSCH scheduled by the DCIs in different control resource set groups in the B carriers is in one slot, the HARQ-ACK feedback is carried on different PUCCH resources.

Optionally, r can be configured by higher layer signaling.

Optionally, r can be reported by the terminal device.

Optionally, the number of second carriers is

Among them, K is the number of carriers configured or activated by high-level signaling, j is the carrier number, and r _j is a positive number greater than or equal to 1 and is related to the number of control resource set groups configured in the j-th carrier. For example, if one control resource set group is configured in the j=1 carrier, then r ₁ =1, and two control resource set groups are configured in the j=2 carrier, then r ₂ =2.

The number of first carriers reported by the terminal device represents that when the maximum number of carriers that it supports to perform data processing operations using time interval #2 is X, X is an integer greater than 1. Specifically, the method for determining the maximum number of carriers is: the actual number of configured carriers A+rⅹthe actual configured number of carriers B, when the actual configured number of carriers A+rⅹthe actual configured number of carriers B is not greater than X, then the number of carriers on all carriers Data scheduling supports time interval #2 to perform data processing operations. Wherein, the number of carriers 1 is the number of carriers without CORESET grouping information, or the number of carriers with only one CORESET grouping information configured, and the number of carriers 2 is the number of carriers configured with two or more CORESET grouping information. The value of r can be pre-defined, such as r=2, or configured by the base station, such as defining the respective value of r on each carrier, or the value of r can be reported by the terminal device, for example, the terminal device can The reported value of r is 1, or 1.5, or 2, or one of the multiple values in [1,2]. For example, suppose r is 2 and X=3 reported by the terminal equipment. When the base station is configured with two carriers, two CORESET groups are configured on carrier 1, and one CORESET group is configured on carrier 2, then the scheduling on

carriers

1 and 2 PDSCH supports the use of time interval #2. For another example, suppose r is 2 and X=3 reported by the terminal device. When the base station is configured with two carriers, and two CORESET groups are configured on both carrier 1 and carrier 2, the PDSCH scheduled on

carriers

1 and 2 does not support the use of Time interval #2.

Optionally, when the terminal device reports that the number of carriers that it supports to perform data processing operations using time interval #2 is 1, then when at least one carrier is configured with two CORESET groups in the actually configured carriers, or in other words, two CORESET groups are configured. CORESET grouping information, for example, CORESET 1 belongs to CORESET group 1, CORESET 2 belongs to CORESET group 2. If a CORESET group is configured in the carrier with the lowest carrier number or no CORESET group is configured, the terminal device supports support in the carrier with the lowest number Using time interval #2, if there are multiple CORESET groups in the carrier with the lowest carrier number, the terminal device only supports the PDSCH scheduled by the CORESET with the smallest CORESET group number in the carrier with the lowest carrier number, using time interval #2. For example, if the base station is configured with two carriers, CORESET group 1 and CORESET group 2 are configured on carrier 1, and CORESET group 1 is configured on carrier 2, the PDSCH scheduled by the DCI issued in CORESET group 1 on carrier 1 supports the use of Time interval #2.

Optionally, when the terminal device reports that it only supports one carrier that uses time interval #2 to perform data processing operations, when at least one carrier is configured with two CORESET groups in the actually configured carriers, the terminal device only supports The PDSCH scheduled by the CORESET with the smallest group number in the carrier with the smallest number of the CORESET group number adopts time interval #2. For example, if the base station is configured with two carriers, CORESET group 2 is configured on carrier 1, and CORESET group 1 and CORESET group 2 are configured on carrier 2, the PDSCH scheduled by DCI issued in CORESET group 1 on carrier 2 supports the use of Time interval #2.

Optionally, when the terminal device reports that it only supports one carrier that uses time interval #2 to perform data processing operations, when at least one carrier is configured with two CORESET groups in the actually configured carriers, the terminal device only supports The carrier with the lowest carrier number in a CORESET group supports time interval #2. For example, if the base station is configured with two carriers, CORESET group 1 is configured on carrier 1, and CORESET group 1 and CORESET group 2 are configured on carrier 2, then the DCI issued in CORESET group 1 and CORESET group 2 on carrier 2 is scheduled The PDSCH supports time interval #2.

Optionally, the terminal device can report its scheduling-restricted data processing capability. The scheduling-restricted data processing capability means that the terminal device can support using time interval #2 to perform subcarrier interval when condition 1 is met. It is a 30kHz PDSCH processing operation, where condition 1 is: only one carrier is configured in a band, and the subcarrier spacing of this carrier is 30kHz, and the number of RBs occupied by the PDSCH does not exceed 136, and there is no Configure the CORESET group information, or the CORESET in the carrier belongs to the same group.

Optionally, the terminal device can report its scheduling-restricted data processing capability. The scheduling-restricted data processing capability means that the terminal device can support using time interval #2 to perform subcarrier interval when condition 1 is met. It is a 30kHz PDSCH processing operation, where condition 1 is: only one carrier is configured in a band, and the subcarrier spacing of the carrier is 30kHz, and the number of RBs occupied by the PDSCH does not exceed L, and at least Two CORESET groups are configured, where the value of L is a positive integer less than 136.

The embodiment of the present application also provides another method for receiving data, which is described below.

PDCCH candidates represent the processing unit that performs PDCCH detection. PDCCH candidates can be configured in the cell public search space and user-specific search space. Each PDCCH candidate is associated with a control resource set, and each PDCCH candidate corresponds to a specific aggregation level. , Different aggregation levels correspond to different numbers of CCEs, or different aggregation levels correspond to different numbers of frequency domain resources. The maximum number of detected PDCCH candidates in a carrier with a subcarrier spacing of μ in a slot is

Among them, μ∈{0,1,2,3}, the specific value of PDCCH quantity is shown in the following table:

The terminal device reports the number of the first carrier it supports

Used to determine the number of PDCCH candidate processing units that the terminal device can support. Specifically: When the number of carriers configured by the base station is not more than

which is

Each carrier can support the largest

PDCCH candidates; when the number of carriers configured by the base station is more than

which is

The number of PDCCH candidates in all carriers with a sub-carrier spacing of μ is not more than

And the number of PDCCH candidates in a carrier with a sub-carrier spacing of μ is not more than

among them,

It is the number of carriers whose subcarrier spacing is μ configured in a slot.

At the same time, for a carrier, when the number of PDCCH candidates configured by the base station exceeds the maximum number of PDCCH candidates that the UE can support as defined above, the terminal device will use the following mechanism to determine the detected PDCCH candidates and discard some of the PDCCH candidates to make the actual detected PDCCH candidates The number of PDCCH candidates does not exceed the detection capability of the terminal equipment: The first step is to remove the maximum number of PDCCH candidates in each carrier determined above from the number of PDCCH candidates in the cell specific search space (CSS) of the carrier

The following number is taken as the maximum number of PDCCH candidates in the User specific search space (USS):

The second step is to start a loop from the search space with the smallest number of the user-specific search space: if the number of PDCCH candidates in the current search space is superimposed on the number of PDCCH candidates in all search spaces with numbers smaller than the current search space, the number of PDCCH candidates in all search spaces is less than

Then the PDCCH candidates in the current search space need to be detected, and the loop until the number of PDCCH candidates in the current search space exceeds

until.

Combining the above-mentioned PDCCH detection mechanism and considering multi-station cooperation scenarios, one carrier may support multiple stations to schedule data at the same time. For example, two control resource set grouping information may be configured in one carrier, and each control resource set grouping information can implicitly correspond A transmission site. There are two existing methods for determining the maximum number of PDCCH candidate processing units (PDCCH candidates):

Manner 1: Limit the maximum number of PDCCH candidate processing units in each control resource set group in each carrier. For example, when the number of carriers configured by the base station is not more than

which is:

among them,

Is the number of configured control resource set groups is 1 or the number of carriers in which no control resource set group is configured,

For the number of carriers whose number of configured control resource collection groups is greater than 1, each control resource collection group in each carrier can support the maximum

which is:

And the number of PDCCH candidates for each control resource set group in each carrier with a subcarrier spacing of μ is not more than

When the number of PDCCH candidates configured by the base station exceeds the maximum number of PDCCH candidates that the UE can support as defined above, the terminal device can determine the number of PDCCH candidates in each control resource set group in each carrier according to the above mechanism.

Number of PDCCH candidates in the search space (Cell specific search space, CSS)

until.

Manner 2: Limit the maximum number of PDCCH candidate processing units in each carrier. For example, when the number of carriers configured by the base station is not more than

which is:

among them,

For the number of carriers whose number of configured control resource set groups is greater than 1, each carrier with a subcarrier spacing of μ can support the largest

which is:

And the number of PDCCH candidates in a carrier with a subcarrier spacing of μ can support the maximum

When the number of PDCCH candidates configured by the base station exceeds the maximum number of PDCCH candidates that the UE can support as defined above, the terminal device can determine the number of PDCCH candidates in the group according to the above mechanism in each carrier. That is, for a carrier, when the number of PDCCH candidates configured by the base station exceeds the maximum number of PDCCH candidates that the UE can support as defined above, the terminal device will use the following mechanism to determine the detected PDCCH candidates and discard some of the PDCCH candidates to make the actual detected PDCCH candidates The number of PDCCH candidates does not exceed the detection capability of the terminal equipment: The first step is to remove the maximum number of PDCCH candidates in each carrier determined above from the number of PDCCH candidates in the cell specific search space (CSS) of the carrier

until.

Among them, each CORESET will be divided into multiple control channel elements (Control Channel Elements, CCE), each CCE includes 6 physical resource blocks (Physical Resource Block, PRB) in the frequency domain and 1 OFDM in the time domain Symbol, each PDCCH candidate can occupy a different number of CCEs, which corresponds to different aggregation levels. In order to reduce the DCI detection complexity of the terminal equipment, the maximum number of non-overlapping CCEs in a carrier with a subcarrier spacing of μ in a slot is defined as

Among them, μ∈{0,1,2,3}, the specific quantity values are shown in the following table:

which is

which is

The number of non-overlapping CCEs in all sub-carriers with a spacing of μ is not more than

And the number of non-overlapping CCEs in the carrier with a subcarrier spacing of μ is not more than

among them,

CCE so that the number of non-overlapping CCEs does not exceed the detection capability of the terminal equipment: the first step is to remove the maximum number of non-overlapping CCEs in each carrier determined above from the cell specific search space (Cell specific search space, Number of non-overlapping CCEs in CSS)

The following number is used as the maximum number of non-overlapping CCEs in the User specific search space (USS):

The second step is to start looping from the search space with the smallest number of the user-specific search space: if the number of non-overlapping CCEs in the current search space is superimposed on the number of non-overlapping CCEs in all search spaces with a smaller number than the current search space, the number of non-overlapping CCEs in all search spaces is less than

Then all PDCCH candidates in the current search space need to be detected, and the loop is repeated until the number of non-overlapping CCEs in the current search space exceeds

until.

which is:

among them,

A non-overlapping CCE; when the base station configures more than

which is:

And the number of non-overlapping CCEs in each control resource set group in each subcarrier interval μ is not more than

The number of CCEs. That is: for a control resource set group in a carrier, when the number of non-overlapping CCEs configured by the base station exceeds the maximum number of non-overlapping CCEs that the UE can support as defined above, the terminal equipment will use the following mechanism to determine non-overlapping CCE discards some non-overlapping CCEs so that the number of non-overlapping CCEs actually detected does not exceed the detection capability of the terminal device: the first step is to determine the number of non-overlapping CCEs in each control resource set group in each carrier determined above The maximum value removes the number of non-overlapping CCEs in the cell specific search space (CSS) in the carrier

Then the PDCCH candidates in the current search space need to be detected, and the loop until the number of non-overlapping CCEs in the current search space exceeds

until.

Method 2: Limit the maximum number of non-overlapping CCEs in each carrier. For example, when the number of carriers configured by the base station is not more than

which is:

among them,

which is:

And the number of non-overlapping CCEs in each sub-carrier interval μ can support the maximum
