Detailed Description
So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Before describing the channel processing method provided in the embodiment of the present application in detail, an Ultra-Reliable Low Latency communication (URLLC) service is briefly described.
New Radio (NR) supports multiple types of services, including: enhanced Mobile Broadband (eMBB), URLLC, and the like. The eMBB service is characterized by a large amount of data and a high transmission rate, and generally uses a large amount of physical resources for transmission, which is not sensitive to delay. The URLLC service is characterized by that the generation of data packet is bursty and random, and has high requirement for delay. A terminal device supporting URLLC service transmission usually needs to support UE processing capability 2 to meet the delay requirement of URLLC service.
In order to guarantee the performance requirement of URLLC service, the current 3GPP discussion considers that the support physical layer can identify the type of service or priority of service carried by currently transmitted PDSCH/PUSCH. When the resources occupied by the physical channels with different priorities conflict, the information carried by the physical channel with high priority is preferentially ensured to be transmitted. Specifically, it is ensured that the information corresponding to the URLLC service is transmitted preferentially. The method for determining the priority of the physical channel can comprise the following steps:
1) the priority of the corresponding physical channel is determined by the DCI format used to schedule the physical channel.
2) The priority of the corresponding physical channel is determined by a Radio Network Temporary Identity (RNTI) adopted by DCI used for scheduling the physical channel.
3) The priority of the corresponding physical channel is determined by a display information field included in DCI used for scheduling the physical channel.
4) The priority of the corresponding physical channel is determined by transmitting a resource, such as a Control-resource set (CORESET) or a search space, of DCI used for scheduling the physical channel.
The processing delay of the Physical Downlink Shared CHannel (PDSCH) is briefly described.
In the NR Rel-15 system, for PDSCH processing delay, after a terminal device (User Equipment, UE) receives scheduling of Downlink Control Information (DCI) format 1_0 or DCI 1_1, the terminal device receives a PDSCH in a corresponding time slot and transmits acknowledgement/negative acknowledgement (ACK/NACK) feedback Information to the network device. The time for the terminal equipment to start sending the ACK/NACK feedback information is not earlier than T after the end position of one time domain symbol occupied by the PDSCH corresponding to the ACK/NACK feedback informationproc,1＝(N 1+d 1,1)(2048+144)·κ2 -μ·T Cms. And if the time requirement is not met, the terminal equipment does not send ACK/NACK feedback information. Wherein, N1 has different values according to the processing capacity of the terminal device. The NR Rel-15 supports two UE processing capabilities, namely UE processing capability 1 and UE processing capability 2, where N1 values corresponding to the UE processing capability 1 are shown in table 1, and N1 values corresponding to the UE processing capability 2 are shown in table 2. When different subcarrier intervals are adopted for uplink transmission and/or downlink transmission, the value of N1 is obtained on the basis of mu; wherein μ is (μ)PDCCH,μ PDSCH,μ UL) In such a way thatproc,1Maximum one value, muPDCCHCorresponding to the carrier spacing, mu, used by PDCCH scheduling PDSCHPDSCHCorresponding to the subcarrier spacing, mu, used by PDSCHULCorresponding to the subcarrier spacing used for transmitting the ACK/NACK feedback information.
For adoption of UE processing capability 2 and muPDSCHWhen the number of frequency domain resource blocks occupied by the scheduled target PDSCH exceeds 136 (corresponding subcarrier spacing is 30kHz), the terminal device returns to UE processing capability 1. The terminal device may skip demodulating (skip decoding) other PDSCHs received within 10 time domain symbols before the target PDSCH starting symbol using UE processing capability 2.

For adoption of UE processing capability 2 and muPDSCHWhen the number of frequency domain resource blocks occupied by the scheduled target PDSCH exceeds 136 (corresponding subcarrier spacing is 30kHz), the terminal device returns to UE processing capability 1. The terminal device may skip demodulating (skip decoding) other PDSCHs received within 10 time domain symbols before the target PDSCH starting symbol using UE processing capability 2. For example, as shown in fig. 1, three downlink channels, namely PDSCH0, PDSCH1 and PDSCH2, are transmitted in a specific time interval, and the specific time interval is 10 time domain symbols, for example, when PDSCH is transmitted in a sub-carrier interval of 30KHz, when a PDSCH2 carrying a data packet corresponding to an eMBB service is scheduled and the number of Resource Blocks (RBs) occupied by PDSCH2 is greater than 136, the terminal device will not decode PDSCH (PDSCH1 and PDSCH0) received in 10 time domain symbols before PDSCH2 with UE processing capability 2. If the PDSCH in 10 time domain symbols before PDSCH2 carries data corresponding to the URLLC service, the transmission performance of the URLLC service will be affected.

As shown in fig. 3, an optional processing flow of the channel processing method provided in the embodiment of the present application includes the following steps:
step S201, the terminal device determines not to receive and/or not to demodulate one of the first downlink channel and the second downlink channel based on the channel priority information of the first downlink channel and the second downlink channel.
In some embodiments, the terminal device determines not to receive and/or not to demodulate one downlink channel based on the channel priority information of the first downlink channel and the second downlink channel; the determining that one downlink channel which is not received and/or not demodulated is one of the first downlink channel and the second downlink channel. As an example, the terminal device determines to receive and/or demodulate the other downlink channel of the first downlink channel and the second downlink channel, and does not receive and/or demodulate one downlink channel of the first downlink channel and the second downlink channel, based on the channel priority information of the first downlink channel and the second downlink channel.
In some embodiments, the first downlink channel and the second downlink channel correspond to different terminal device processing capabilities; for example, the first downlink channel corresponds to a first terminal device processing capability, and the second downlink channel corresponds to a second terminal device processing capability; or, the first downlink channel corresponds to a second terminal device processing capability, and the second downlink channel corresponds to a first terminal device processing capability; the first terminal device processing capability is different from the second terminal device processing capability. Wherein the physical channel processing time of the terminal device under the processing capability of the second terminal device is shorter than the physical channel processing time under the processing capability of the first terminal device; therefore, it can also be understood that the second terminal device has a higher level of processing capability than the first terminal device. The second terminal device processing capability corresponds to the aforementioned UE processing capability 2, and the first terminal device processing capability corresponds to the aforementioned UE processing capability 1.
In some embodiments, a time interval between the first downlink channel and the second downlink channel is less than or equal to a time interval threshold. The time interval threshold comprises at least one of: characterized by the number of time domain symbols; an absolute time; the appointed value or the appointed parameter representation related to the downlink channel transmission subcarrier interval; and the physical channel processing time of the terminal equipment under the processing capacity of the second terminal equipment is less than or equal to. If the time interval threshold is M time domain symbols, the time interval between the first downlink channel and the second downlink channel is less than or equal to M. If the time domain threshold is N milliseconds, the time interval between the first downlink channel and the second downlink channel is less than or equal to N milliseconds. If the time interval threshold is characterized by the parameters related to the downlink channel transmission subcarrier interval, the terminal equipment can determine the physical channel processing time of the terminal equipment according to the parameters related to the downlink channel transmission subcarrier interval, and the time interval threshold is smaller than the determined physical channel processing time of the terminal equipment; optionally, the parameter related to the downlink channel transmission subcarrier interval is μ in table 1 and table 2, and μ has a corresponding relationship with the downlink channel transmission subcarrier interval. And if the time interval threshold is less than or equal to the physical channel processing time of the terminal equipment under the processing capacity of the second terminal equipment, and the physical channel processing time of the terminal equipment under the processing capacity of the second terminal equipment is T, the time interval between the first downlink channel and the second downlink channel is less than or equal to T.
Wherein, the time interval between the first downlink channel and the second downlink channel being less than or equal to the time interval threshold includes at least the following four cases: 1) as shown in fig. 4, a time interval between a first downlink channel and a second downlink channel is smaller than or equal to a time interval threshold, where a time interval between a start symbol of the second downlink channel and an end symbol of the first downlink channel is smaller than the time interval threshold. 2) As shown in fig. 5, a time interval between the first downlink channel and the second downlink channel is smaller than or equal to a time interval threshold, and a time interval between the end symbol of the second downlink channel and the end symbol of the first downlink channel is smaller than the time interval threshold. 3) Fig. 6 shows that the time interval between the first downlink channel and the second downlink channel is less than or equal to the time interval threshold, and as shown in fig. 6, the time interval between the end symbol of the first downlink channel and the start symbol of the second downlink channel is less than the time interval threshold. 4) As shown in fig. 7, a time interval between the first downlink channel and the second downlink channel is smaller than or equal to a time interval threshold, and as shown in fig. 7, a time interval between the start symbol of the first downlink channel and the start symbol of the second downlink channel is smaller than the time interval threshold.
In other embodiments, if the first downlink channel corresponds to a processing capability of a first terminal device, and the second downlink channel corresponds to a processing capability of a second terminal device, the time interval threshold is a first threshold; the first threshold is smaller than or equal to the physical channel processing time of the terminal equipment under the processing capacity of the first terminal equipment.
In still other embodiments, if the first downlink channel corresponds to a processing capability of a second terminal device, and the second downlink channel corresponds to a processing capability of the first terminal device, the time interval threshold is a second threshold; the second threshold is less than or equal to the physical channel processing time of the terminal device under the processing capacity of the second terminal device.
The following description is directed to determining, by a terminal device, not to receive and/or not to demodulate one downlink channel of a first downlink channel and a second downlink channel based on channel priority information of the first downlink channel and the second downlink channel:
in some optional embodiments, the terminal device determines not to receive and/or not to demodulate a downlink channel with a lower priority of the first downlink channel and the second downlink channel; correspondingly, the terminal device receives and/or demodulates the downlink channel with the higher priority in the first downlink channel and the second downlink channel.
In other optional embodiments, in a case that the priorities of the first downlink channel and the second downlink channel are the same, the terminal device determines not to receive and/or not to demodulate the second downlink channel with a later transmission time; correspondingly, the terminal equipment receives and/or demodulates the first downlink channel with the transmission time ahead.
In still other optional embodiments, in a case that the priority of the first downlink channel is the same as that of the second downlink channel, the terminal device determines not to receive and/or not to demodulate the first downlink channel with a previous transmission time; correspondingly, the terminal equipment receives and/or demodulates the second downlink channel with the later transmission time.
The embodiment of the application can further comprise:
step S202, the terminal device reports the processing capacity of the terminal device supporting the second terminal device to the network device.
In some embodiments, when the terminal device not only supports the processing capability of the first terminal device, but also supports the processing capability of the second terminal device different from the first processing capability, the terminal device reports the processing capability of the second terminal device supported by the terminal device to the network device; the first terminal device processing capability and the second terminal device processing capability are both used for the terminal device to receive and/or demodulate the downlink channel.
Step S203, the terminal device receives information sent by the network device, where the information is used to configure the terminal device to receive and/or demodulate the downlink channel according to the channel priority information.
In some embodiments, the information may be dedicated signaling sent by the network device to the terminal device; the information may also be common signaling sent by the network device to the terminal device.
Step S204, the terminal equipment determines the processing capacity of the terminal equipment corresponding to the downlink channel.
In some embodiments, the downlink channels include the first downlink channel and the second downlink channel, and the terminal device determines a processing capability of the terminal device corresponding to the first downlink channel and/or a processing capability of the terminal device corresponding to the second downlink channel.
The terminal device processing capability corresponding to the first downlink channel refers to that the terminal device receives and/or demodulates the first downlink channel based on the terminal device processing capability. Correspondingly, the processing capability of the terminal device corresponding to the second downlink channel refers to that the terminal device receives and/or demodulates the second downlink channel based on the processing capability of the terminal device.
The implementation method for determining the processing capability of the terminal device corresponding to the downlink channel for the terminal device at least comprises the following steps:
in some embodiments, the terminal device determines, according to priority information of a downlink channel, a processing capability of the terminal device corresponding to the downlink channel; if the processing capacity level of the terminal equipment corresponding to the downlink channel with high priority is higher than that of the terminal equipment corresponding to the downlink channel with low priority; the processing time of the physical channel of the terminal equipment under the high-level terminal equipment processing capacity is shorter than that under the low-level terminal equipment processing capacity. For example, if the priority of the first downlink channel is higher than the priority of the second downlink channel, the terminal device determines that the first downlink channel corresponds to the processing capability of the second terminal device, and the second downlink channel corresponds to the processing capability of the first terminal device. The physical channel processing time of the terminal equipment under the processing capacity of the second terminal equipment is shorter than the physical channel processing time under the processing capacity of the terminal equipment at a low level; i.e. the second terminal device processing capability level is higher than the first terminal device processing capability level.
In other embodiments, the terminal device determines, according to the transmission parameter of the downlink channel, the processing capability of the terminal device corresponding to the downlink channel. Wherein the transmission parameter may include at least one of: subcarrier spacing, time domain length, modulation coding grade, transmission block size, physical resource block number and precoding mode. For example, among the transmission parameters: and under the condition that the values of the subcarrier interval, the time domain length, the modulation coding grade, the transmission block size and the physical resource block number are larger, the terminal equipment determines the processing capacity of the terminal equipment with the high level corresponding to the downlink channel. When the transmission parameter includes a precoding mode, the processing capability of the terminal device corresponding to the downlink channel may be determined according to a corresponding relationship between a preset precoding mode and the processing capability of the terminal device. It should be noted that, the above is only an example of the content included in the transmission parameter, and the content included in the transmission parameter is not limited; any parameter that can characterize the transmission performance of the channel is within the scope of the transmission parameters of the present application.
In still other embodiments, if the terminal device determines to receive and/or demodulate the downlink channel based on the processing capability of the second terminal device according to the priority information, the terminal device determines to receive and/or demodulate the downlink channel based on the processing capability of the first terminal device if the transmission parameter in the downlink channel satisfies the first condition. Optionally, the first condition comprises: the subcarrier spacing is 30KHz and the number of RBs occupied by the downlink channel is more than 136. For example, the network device configures the terminal to receive and/or demodulate the downlink channel on a certain carrier based on the processing capability of the second terminal device. If the PDSCH currently scheduled by the network equipment adopts 30kHz subcarriers and the scheduling bandwidth exceeds 136RB, the terminal equipment receives and/or demodulates the PDSCH based on the processing capacity of the first terminal equipment; otherwise, the second terminal equipment processing capability is adopted to receive and/or demodulate the PDSCH. If the terminal device has determined to receive and/or demodulate the downlink channel based on the processing capability of the second terminal device, but the terminal device determines that the transmission parameter satisfies the first condition, the terminal device performs capability rollback, that is, the terminal device performs channel processing by adopting the processing capability of the second terminal device with a high level to adopting the processing capability of the first terminal device with a low level.
In some further embodiments, if the terminal device determines, based on the transmission parameter, that the second terminal device has the processing capability to receive and/or demodulate the downlink channel, if the priority information of the downlink channel corresponds to the processing capability of the first terminal device, the terminal device determines, based on the processing capability of the first terminal device, to receive and/or demodulate the downlink channel.
It should be noted that, in this embodiment of the application, the priority information of the channel at least includes priority information of a service carried by a downlink channel. For example, the first PDSCH carries data corresponding to URLLC traffic, the second PDSCH carries data corresponding to eMBB traffic, and the priority of URLLC traffic is higher than the priority of eMBB traffic, so the priority of the first PDSCH is higher than the priority of the second PDSCH. Or, the downlink channel has a priority; for example, the first PDSCH itself has a higher priority than the second PDSCH itself, and the first PDSCH has a higher priority than the second PDSCH regardless of the type of data carried by the first PDSCH and the second PDSCH.
In the following, for different scenarios, how the terminal device receives and/or demodulates two downlink channels when the time interval between the first downlink channel and the second downlink channel is less than or equal to the time interval threshold is illustrated.
In some scenarios, the terminal device receives and demodulates the first PDSCH on the target time domain resource based on the processing capability of the second terminal device, the channel priority of the first PDSCH is higher than the channel priority of the second PDSCH, and the terminal device needs to receive the second PDSCH based on the processing capability of the first terminal device; and the physical channel processing time of the terminal equipment under the processing capacity of the second terminal equipment is shorter than that under the processing capacity of the first terminal equipment. Within a time interval threshold after the end symbol of the first PDSCH, the terminal device does not receive and/or demodulate the second PDSCH; and the terminal equipment receives and/or demodulates the first PDSCH, namely the terminal equipment receives and/or demodulates the downlink channel with high priority. In this scenario, a time interval between the start symbol of the second downlink channel and the end symbol of the first downlink channel is smaller than the time interval threshold; or, a time interval between the end symbol of the second downlink channel and the end symbol of the first downlink channel is smaller than the time interval threshold.
Wherein the terminal device not receiving and/or not demodulating the second PDSCH may include the following two cases: the first case is that the terminal device does not expect to receive and/or does not expect to demodulate the second PDSCH, i.e. the network device has scheduling restrictions, i.e. does not schedule the second PDSCH. In the second case, the scheduling of the second PDSCH by the network device is not restricted, and the terminal device does not receive and/or demodulate the second PDSCH; i.e., the network device may schedule the second PDSCH, but the terminal device does not receive and/or demodulate the second PDSCH.
The following is exemplified for this scenario: if the first PDSCH bears the data of the URLLC service, the terminal equipment receives and/or demodulates the first PDSCH based on the processing capacity of the second terminal equipment, the network equipment schedules the second PDSCH within a time interval threshold, the second PDSCH bears the data of the eMBB service, the number of RBs occupied by a second PDSCH channel is more than 136, and the subcarrier interval corresponding to the second PDSCH is 30 MHz; the terminal device does not receive and/or demodulate the second PDSCH. Compared with the existing scheme that the terminal equipment gives up demodulating the first PDSCH and receives and/or demodulates the second PDSCH, the method can ensure that the URLLC service with high requirement on time delay is not influenced by the eMBB service with low requirement on time delay.
In other scenes, the terminal equipment determines that a second PDSCH needs to be received on a target time domain resource, wherein the second PDSCH needs to be received by the terminal equipment based on the processing capacity of the first terminal equipment; and if the terminal equipment does not receive and/or demodulate the first PDSCH within a time interval threshold before the starting symbol of the second PDSCH, the terminal equipment receives and/or demodulates the second PDSCH. The terminal device does not receive and/or demodulate the first PDSCH, and may not transmit the first PDSCH for the network device.
In still other scenarios, the terminal device receives, but does not demodulate, the first PDSCH on the target time domain resource based on the second terminal device processing capability, the channel priority of the second PDSCH being higher than the channel priority of the first PDSCH; the terminal device receives and demodulates the second PDSCH and relinquishes demodulation of the first PDSCH. I.e. the terminal device receives and/or demodulates the second PDSCH with high priority. Or, if the channel priority of the first PDSCH is equal to the channel priority of the second PDSCH, the terminal device demodulates the first PDSCH with the previous transmission time, and does not receive and/or demodulate the second PDSCH with the next transmission time. Or, if the channel priority of the first PDSCH is equal to the channel priority of the second PDSCH, the terminal device receives and/or demodulates the second PDSCH with the later transmission time, and does not demodulate the first PDSCH with the earlier transmission time. In this way, when two PDSCHs with the same priority are scheduled for transmission, the transmission performance of the PDSCHs transmitted later is ensured by receiving and/or demodulating the PDSCHs with later transmission time. Or, if the channel priority of the first PDSCH is equal to the channel priority of the second PDSCH, the terminal device receives and/or demodulates the second PDSCH with the previous transmission time, and does not demodulate the second PDSCH with the next transmission time. In this way, when two PDSCHs with the same priority are scheduled for transmission, the transmission performance of the previously transmitted PDSCH is ensured by receiving and/or demodulating the PDSCH with the previous transmission time. In this scenario, a time interval between the start symbol of the second downlink channel and the end symbol of the first downlink channel is smaller than the time interval threshold, or a time interval between the end symbol of the second downlink channel and the end symbol of the first downlink channel is smaller than the time interval threshold.
In some other scenarios, the terminal device determines that a second PDSCH needs to be received on the target time domain resource, where the second PDSCH needs to be received by the terminal device based on the processing capability of the first terminal device, and the priority of the second PDSCH is higher than that of the first PDSCH, then the terminal device does not demodulate the first PDSCH, and the terminal device receives and/or demodulates the second PDSCH; namely, the terminal equipment receives and/or demodulates the downlink channel with high priority. And if the priority of the first PDSCH is equal to that of the first PDSCH, the terminal equipment receives and/or demodulates the second PDSCH with the later transmission time, and does not demodulate the first PDSCH with the earlier transmission time. In this way, when two PDSCHs with the same priority are scheduled for transmission, the transmission performance of the PDSCHs transmitted later is ensured by receiving and/or demodulating the PDSCHs with later transmission time. Or, if the channel priority of the first PDSCH is equal to the channel priority of the second PDSCH, the terminal device receives and/or demodulates the second PDSCH with the previous transmission time, and does not demodulate the second PDSCH with the next transmission time. In this way, when two PDSCHs with the same priority are scheduled for transmission, the transmission performance of the previously transmitted PDSCH is ensured by receiving and/or demodulating the PDSCH with the previous transmission time. In this scenario, a time interval between the ending symbol of the first downlink channel and the starting symbol of the second downlink channel is smaller than the time interval threshold, or a time interval between the starting symbol of the first downlink channel and the starting symbol of the second downlink channel is smaller than the time interval threshold.
