Description

Channel transmission method and related equipment

Technical field

This application relates to the field of communication technology, and in particular to a channel transmission method and related equipment.

Background technique

In the fifth generation (Fifth Generation, 5G) communication system, the multi-transmission and reception point (Multi-TRP) transmission technology is a key technology to improve the overall performance of the system and solve the problem of inter-cell interference. Multi-TRP transmission technology includes multiple schemes such as joint transmission technology, dynamic transmission point selection technology, and coordinated scheduling.

At present, in the Multi-TRP transmission technology, multiple network devices are allowed to send different downlink control information to the same terminal device, so that the terminal device can send corresponding physical uplink control information to the corresponding network device according to each downlink control information. Channel (Physical Uplink Control Channel, PUCCH), Physical Uplink Shared Channel (Physical Uplink Share Channel, PUSCH). Since multiple TRPs cannot exchange real-time information, it is expected that the UCI information carried on the PUCCH or PUSCH can be sent to the corresponding network device in real time. However, when a terminal device sends PUCCH and PUSCH to different network devices, multiple PUCCH and PUSCH resources may overlap. Therefore, when multiple PUCCH and PUSCH overlap, how to transmit these uplink channels becomes an urgent problem to be solved. The problem.

Summary of the invention

This application provides a channel transmission method and related equipment, which can transmit at least one uplink channel when resources occupied by multiple uplink channels overlap.

In the first aspect, the present application provides a channel transmission method. In the channel transmission method, the terminal determines that the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the terminal can send the second uplink control channel. At least one of an uplink shared channel and the second uplink control channel. It can be seen that the channel transmission method can realize the transmission of at least one uplink channel when the resources occupied by multiple uplink channels overlap in the coordinated multi-point transmission, which is beneficial to avoid all the overlapping uplink channels being unable to transmit, resulting in the loss of transmission resources. Waste, so that at least one of the network device corresponding to the first uplink shared channel and the network device corresponding to the second uplink control channel obtains uplink control information.

In an optional embodiment, the terminal sending at least one of the first uplink shared channel and the second uplink control channel may include: the terminal sending the first uplink shared channel and the The second uplink control channel. Wherein, the first uplink shared channel and the second uplink control channel are sent, and the resources occupied by the first uplink shared channel are punctured. Wherein, the resources occupied by the second uplink control channel do not overlap with the resources occupied by the demodulation reference signal (Demodulation Reference Signal, DMRS) corresponding to the first uplink shared channel, and the second uplink control channel carries information The total number of bits is less than or equal to the first preset threshold, and the terminal transmits the first uplink shared channel and the second uplink control by puncturing the resources occupied by the first uplink shared channel channel.

In another optional embodiment, the terminal sending at least one of the first uplink shared channel and the second uplink control channel may include: the terminal sending the first uplink shared channel and the One of the second uplink control channels. Wherein, the resource occupied by the second uplink control channel overlaps with the resource occupied by the demodulation reference signal corresponding to the first uplink shared channel, or the total number of bits of information carried by the second uplink control channel is greater than all For the first preset threshold, the terminal sends one of the first uplink shared channel and the second uplink control channel.

It can be seen that in the above two implementation manners, the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel do not overlap, that is, the second uplink control channel does not affect the first uplink shared channel When the corresponding DMRS, and the total number of bits of information carried by the second uplink control channel is less than or equal to the first preset threshold, the terminal can both send the two overlapping uplink channels; and the second uplink control channel affects the first uplink sharing The DMRS corresponding to the channel, or when the total number of bits of information carried by the second uplink control channel is greater than the first preset threshold, one of the two overlapping uplink channels may be sent. Therefore, the above two implementation manners are beneficial for the terminal to feed back the uplink control information (Uplink control information, UCI) carried by at least one uplink channel.

The first preset threshold may be a preset total number of bits of information carried by the uplink control channel. The first preset threshold may be 2 bits or 4 bits, etc. The first preset threshold can be configured according to requirements.

In one case, the terminal may consider whether the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel overlap, and determine whether the puncturing method can be used to transmit the first uplink shared channel. Channel and the first uplink control channel. In another case, the terminal may also consider whether the transmission power of the resource position overlapping between the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel exceeds the maximum transmission power. If it exceeds the maximum transmission power, it may not be considered "Multiplexing", just select a channel for transmission; if the maximum transmission power is not exceeded, the preconditions of the first case mentioned above can be further considered. It can be seen that the prerequisite of the second case can prevent the transmission power of the uplink shared channel after the resources occupied by the uplink shared channel are punctured, and the uplink shared channel cannot be received.

In an optional implementation manner, the terminal transmits one of the first uplink shared channel and the second uplink control channel. In an optional implementation manner, the terminal sending one of the first uplink shared channel and the second uplink control channel may include: the terminal does not send the first uplink shared channel and sends the first uplink shared channel Two uplink control channels; or, the terminal sends the first uplink shared channel, but does not send the second uplink control channel. Wherein, the information carried by the second uplink control channel includes hybrid automatic repeat request acknowledgement information HARQ-ACK, and the terminal does not send the first uplink shared channel but sends the second uplink control channel; 2. The information carried by the uplink control channel does not include HARQ-ACK, and the terminal sends the first uplink shared channel but does not send the second uplink control channel. It can be seen that, in this embodiment, on the one hand, it is beneficial for the terminal to preferentially send HARQ-ACK to the network device, and on the other hand, it is beneficial for the terminal to preferentially transmit UCI information and/or data carried by the uplink shared channel to the network device.

In a second aspect, this application also provides a channel transmission method. In the channel transmission method, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink shared channel Overlaps with the resources occupied by the first uplink control channel, and the first uplink shared channel is associated with the first uplink control channel; in this case, the terminal may first determine the relationship between the first uplink shared channel and the first uplink control channel sending method. For example, if the timing condition is not satisfied between the first uplink shared channel and the first uplink control channel, the terminal does not send the first uplink shared channel, but sends the first uplink control channel and the second uplink control channel. Control channel; the first uplink shared channel and the first uplink control channel meet the timing condition between the terminal and the first uplink control channel carries part or all of the information carried by the first uplink shared channel Information is multiplexed and carried on the first uplink shared channel, and the step of transmitting at least one of the first uplink shared channel and the second uplink control channel is performed.

It can be seen that this embodiment first focuses on the overlap of the resources occupied by the first uplink shared channel with the resources occupied by the first uplink control channel, and then determines the resources occupied by the first uplink shared channel when the first uplink shared channel is sent. Overlap with the resources occupied by the second uplink control channel, and transmit at least one of the first uplink shared channel and the second uplink control channel; and, in this implementation manner, the first uplink control channel can carry information Part or all of the information in is multiplexed with the information carried by the first uplink shared channel, so as to send as much UCI information carried by the overlapping uplink channels to each network device as much as possible.

In the channel transmission method, the terminal multiplexes part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel, which may include any of the following implementation manners. For example, the terminal uses a method of puncturing the resources of the first uplink shared channel to multiplex HARQ-ACK included in the first uplink control channel carrying information with the information carried by the first uplink shared channel, Wherein, the number of HARQ-ACK bits included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the terminal adopts a rate matching method to add the first uplink control bearer information to The included HARQ-ACK is multiplexed with information carried by the first uplink shared channel, wherein the number of HARQ-ACK bits included in the first uplink control bearer information is greater than the second preset threshold;

Alternatively, the terminal multiplexes the channel state information contained in the first uplink control channel carrying information with the information carried by the first uplink shared channel in a rate matching manner, wherein the first uplink shared channel carries The information does not contain channel state information;

Or, the terminal multiplexes channel state information other than periodic channel state information contained in the first uplink control channel carrying information with the information carried by the first uplink shared channel in a rate matching manner, Wherein, the information carried by the first uplink shared channel includes channel state information.

The second preset threshold may be the preset number of HARQ-ACK bits. The second preset threshold may be 2 bits. The second preset threshold can be configured according to requirements.

In an optional implementation manner, in the first aspect, the terminal transmits one of the first uplink shared channel and the second uplink control channel, and the channel transmission method described in the second aspect The following steps may be included: the terminal does not send the first uplink shared channel and sends the second uplink control channel, wherein the priority of the information carried by the first uplink shared channel is lower than or equal to the first uplink shared channel. 2. Priority of information carried by the uplink control channel; or, the terminal sends the first uplink shared channel but does not send the second uplink control channel, wherein the priority of the information carried by the first uplink shared channel is higher than Or equal to the priority of the information carried by the second uplink control channel. In this aspect, the HARQ-ACK contained in the first uplink control channel carrying information may be carried by the first uplink shared channel. Therefore, this embodiment is based on a priority comparison, which is conducive to sending the information with the highest priority to the network device. .

For example, the priority of the information carried by the first uplink shared channel is determined by the information with the highest priority among the information carried by the first uplink shared channel; the priority of the information carried by the second uplink control channel, It is determined by the information with the highest priority among the information carried by the second uplink control channel. That is, in the second aspect, the information carried by the first uplink shared channel may include at least one of HARQ-ACK and channel state information; and the information carried by the second uplink control channel The information includes at least one uplink control information among hybrid automatic repeat request acknowledgement information HARQ-ACK and channel state information; wherein the priority of the HARQ-ACK is higher than the priority of the channel state information. Therefore, this embodiment is based on the comparison of priorities, which is beneficial to sending uplink control information with a higher priority to the network device.

The channel state information carried by the first uplink control channel may include periodic channel state information (P-CSI), semi-persistent channel state information (semi-persistent channel state information, semi-CSI), etc. The channel state information carried by the second uplink shared channel may include semi-static channel state information (semi-CSI) and aperiodic channel state information (AP-CSI). Among them, the semi-static channel state information (semi-CSI) is configured to be transmitted on which of the uplink control channel and the uplink shared channel, and the UCI information carried by which channel may include the semi-CSI.

In an optional implementation manner, the priority of the HARQ-ACK is higher than the priority of the channel state information, so that the HARQ-ACK can be fed back to the network device as quickly as possible. In another optional implementation manner, the priority of the HARQ-ACK may be lower than the priority of the channel state information, so that the channel state information can be fed back to the network device as quickly as possible. Therefore, the embodiments of the present application do not limit the priorities of the two, and can be predefined or configured specifically in combination with application scenarios.

In an optional implementation manner, the priority between AP-CSI, P-CSI, semi-CSI carried on the first uplink shared channel, and semi-CSI carried on the first uplink control channel may be As follows: "AP-CSI priority" is higher than "semi-CSI carried on the uplink shared channel"; "semi-CSI carried on the uplink shared channel" is higher than "carried on the uplink control "The priority of semi-CSI on the channel"; "The priority of semi-CSI carried on the uplink control channel" is higher than the "Priority of P-CSI". Therefore, in the first and second aspects, when the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel, the P-CSI in the first uplink control bearer information may not be multiplexed, that is, discarded The P-CSI facilitates sending UCI information with a higher priority to the network device, and at the same time, reduces the proportion of resources occupied by the first uplink shared channel by the multiplexing mode.

In another optional implementation manner, the priority of each channel state information described above may also be predefined or configured accordingly according to application scenarios. The embodiments of this application do not make limitations.

In an optional implementation manner, the priority of the information carried by the first uplink shared channel is determined by whether the first uplink shared channel carries HARQ-ACK information; the second The priority of the information carried by the uplink control channel is determined by whether the second uplink control channel carries the HARQ-ACK confirmation information of the hybrid automatic repeat request. Therefore, this embodiment is based on the comparison of priorities, which is beneficial to sending HARQ-ACKs with high priority to the network device, so as to quickly retransmit erroneous data.

In the embodiment of the present application, whether the first uplink control channel is associated with the first uplink shared channel may be determined by whether the respective downlink control related parameters corresponding to each channel are the same.

The uplink control channel is associated with the uplink shared channel, which means that the uplink control channel and the uplink shared channel are sent to the same network device; correspondingly, the uplink control channel is not associated with the uplink shared channel, which means that the uplink control channel and the uplink The shared channels are sent to different network devices separately.

In a third aspect, the present application also provides a channel transmission method. The difference between the channel transmission method and the channel transmission method described in the above two aspects is that in the channel transmission method, the resource occupied by the first uplink control channel is the same as The resources occupied by the first uplink shared channel overlap; the first uplink control channel is associated with the first uplink shared channel; correspondingly, the terminal sends the first uplink shared channel and the first uplink control channel One of them.

Wherein, in this aspect, for the optional implementation manner of "the terminal sends one of the first uplink shared channel and the first uplink control channel", reference may be made to the related content of the above second aspect. For example, sending one of the first uplink shared channel and the first uplink control channel by the terminal may include: the terminal combining part or all of the information carried in the first uplink control channel with the first uplink control channel The information carried by an uplink shared channel is multiplexed and carried on the first uplink shared channel. Furthermore, the terminal may send the first uplink shared channel without sending the first uplink control channel. An uplink control channel meets a timing condition with the first uplink shared channel; or, the terminal does not send the first uplink shared channel and sends the first uplink control channel, wherein the first uplink control The timing condition is not satisfied between the channel and the first uplink shared channel. In addition, for how part or all of the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel, reference may also be made to the related content of the second aspect described above, which will not be detailed here.

In a fourth aspect, the present application also provides a channel transmission method. Compared with the channel transmission method in the third aspect, the channel transmission method has resources occupied by the first uplink control channel overlapping with the resources occupied by the first uplink shared channel. The resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel; in this way, the resources occupied by the terminal for the first uplink control channel overlap with the resources occupied by the first uplink shared channel, To send one of the first uplink shared channel and the first uplink control channel, it is also necessary to determine that the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel. The transmission scheme of the uplink shared channel and the second uplink control channel.

For example, the terminal punctures the resources that overlap the resources occupied by the second uplink control channel on the resources occupied by the first uplink shared channel, transmits the second uplink control channel, and executes the second uplink control channel. The operation of sending one of the first uplink shared channel and the first uplink control channel according to the third aspect, wherein the resource occupied by the second uplink control channel corresponds to the first uplink shared channel The resources occupied by the demodulation reference signal of the reference signal do not overlap, and the total number of bits of information carried by the second uplink control channel is less than or equal to the second preset threshold; or,

The terminal does not send the first uplink shared channel, but sends the second uplink control channel and the first uplink control channel, wherein the resources occupied by the second uplink control channel are shared with the first uplink The resources occupied by the demodulation reference signals corresponding to the channels overlap and the information carried by the second uplink control channel includes HARQ-ACK, or,

The total number of bits of information carried by the second uplink control channel is greater than the preset threshold and the information carried by the second uplink control channel includes HARQ-ACK; or,

The terminal does not send the second uplink control channel, and performs the operation of sending one of the first uplink shared channel and the first uplink control channel as described in the third aspect, wherein the second The resources occupied by the uplink control channel overlap with the resources occupied by the demodulation reference signal in the first uplink shared channel and the information carried by the second uplink control channel does not include HARQ-ACK, or the second uplink The total number of bits of information carried by the control channel is greater than the preset threshold and the information carried by the second uplink control channel does not include HARQ-ACK.

In a fifth aspect, this application also provides a channel transmission method. In the channel transmission method, the terminal and the network device do not agree on the implementation conditions of the above-mentioned optional transmission scheme, that is, the terminal determines the The uplink channel transmission mode when the uplink shared channel overlaps the first uplink control channel and the second uplink control channel, and the network device side does not know how the terminal will send the uplink channel.

For example, the terminal may send the first uplink control channel and the second uplink control channel separately, without sending the first uplink shared channel; or, the terminal may carry part or all of the information carried by the first uplink control channel with the first uplink shared channel The information in the first uplink shared channel is multiplexed and carried on the first uplink shared channel. Then, according to an optional rule, as in the channel transmission method described in the first aspect, the first uplink shared channel and the second uplink control channel are sent At least one, wherein a timing condition is satisfied between the first uplink control channel and the first uplink shared channel.

In the above example, when determining that the second uplink control channel includes HARQ-ACK, the terminal may also perform the steps of sending the first uplink control channel and the second uplink control channel separately without sending the first uplink shared channel.

Correspondingly, for the network device side, the network device corresponding to the first uplink control channel and the first uplink shared channel does not know the transmission scheme selected by the terminal, so it can detect twice for the information carried by the first uplink control channel. That is, the first uplink control channel is detected on the resources of the first uplink control channel respectively. If the detection fails, the first uplink shared channel is detected on the resources of the first uplink shared channel, and the detected first uplink shared channel is still It carries the information carried by the multiplexed first uplink control channel. Specifically, corresponding to the channel transmission methods of the first to fifth aspects described above, the operations on the network device side may refer to the following sixth and seventh aspects.

In a sixth aspect, this application also provides a channel transmission method, which is explained from the perspective of the network device side.

Among them, for the channel transmission methods of the first to fifth aspects, the network device corresponding to the second uplink control channel, such as TRP2, when the resources occupied by the second uplink control channel overlap with the resources occupied by the first uplink shared channel, In one case, the terminal does not send the second uplink control channel. In another case, the terminal sends the second uplink control channel in a punctured manner on the resources of the first uplink shared channel. In another case, the terminal sends the second uplink control channel. 2. Uplink control channel. Therefore, for TRP2, either the normal reception succeeds or the reception fails. Therefore, TRP2 does not need to add other operation modes.

Among them, for the channel transmission methods of the first to fifth aspects, the first uplink control channel and the first uplink shared channel can be associated with the same network device, such as TRP1, and the resources occupied by the first uplink control channel are the same as those of the first uplink. When the resources occupied by the shared channels overlap, in one case, the terminal does not send the first uplink control channel, but multiplexes part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel, and It is carried on the first uplink shared channel and the first uplink shared channel is sent; in another case, the terminal does not send the first uplink shared channel but sends the first uplink control channel. Therefore, for TRP1, either the first uplink control channel is received on the resources of the first uplink control channel, but the first uplink shared channel is not received; or the first uplink control channel is not received, the first uplink shared channel is received, and The first uplink shared channel carries part or all of the information carried by the first uplink control channel. Therefore, the following content explains the channel transmission method described in this aspect from the perspective of TRP1.

In the channel transmission method, the network device receives the first uplink control channel on the resource of the first uplink control channel; the network device receives the first uplink shared channel on the resource of the first uplink shared channel; The network device obtains uplink control information; the uplink control information comes from the first uplink control channel or from the first uplink shared channel; the resources occupied by the first uplink control channel are the same as those of the first uplink The resources occupied by the shared channels overlap, and the first uplink control channel is associated with the first uplink shared channel. That is, when the uplink control information obtained by the network device comes from the first uplink control channel, it only contains the information carried by the first uplink control channel; if it comes from the first uplink shared channel, it may contain the information carried by the first uplink control channel. After being multiplexed with the information carried by the first uplink shared channel, the information carried on the first uplink shared channel, for example, may include UCI carried by the first uplink control channel and UCI carried by the first uplink shared channel.

It can be seen that the network equipment can detect the information carried by the first uplink control channel twice, that is, on the one hand, it can detect on the resources of the first uplink control channel. If it is not detected, it can detect the first uplink on the resources of the first uplink shared channel. The control channel carries part or all of the information. Therefore, it is beneficial to obtain as much uplink control information as possible when resources occupied by multiple uplink channels overlap.

In another optional implementation manner, the network device receives the first uplink shared channel on the resources of the first uplink shared channel; when the network device does not receive the first uplink shared channel, Receiving the first uplink control channel on a resource of an uplink control channel; and, the network device obtains part or all of the information carried by the first uplink control channel from the received first uplink control channel; The first uplink control channel is associated with the first uplink shared channel. It can be seen that the network equipment can detect the uplink control information, that is, on the one hand, it can detect on the resources of the first uplink control channel. If it is not detected, it can detect the part or part of the information carried by the first uplink control channel on the resources of the first uplink shared channel. All information. Therefore, it is beneficial to obtain as much uplink control information as possible when resources occupied by multiple uplink channels overlap.

It can be seen that the channels from which the uplink control information obtained in the above two implementations come are different, and the uplink control information that can be obtained may also be different.

In an optional implementation manner, the HARQ-ACK included in the first uplink control channel bearer information is in a manner of puncturing the resources occupied by the first uplink shared channel, and the first uplink shared channel The information carried by an uplink shared channel is multiplexed and carried on the first uplink shared channel, wherein the number of HARQ-ACK bits contained in the information carried by the first uplink control channel is less than or equal to the second preset Threshold; or, the HARQ-ACK contained in the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel in a rate matching manner and carried on the first uplink shared channel On the channel, the number of HARQ-ACK bits included in the first uplink control channel carrying information is greater than the second preset threshold. It can be seen that this implementation manner is beneficial for the network device to obtain the HARQ-ACK contained in the first uplink control channel bearer information on the resource corresponding to the puncturing method or the resource corresponding to the rate matching.

In an optional implementation manner, the channel state information CSI contained in the first uplink control channel carrying information is multiplexed with the information carried by the first uplink shared channel in a rate matching manner, and is carried in On the first uplink shared channel, the information carried by the first uplink shared channel does not include CSI; or, the channel status except for periodic channel status information P-CSI in the information carried by the first uplink control channel The information is multiplexed with the information carried by the first uplink shared channel in a rate matching manner, and is carried on the first uplink shared channel, wherein the information carried by the first uplink shared channel includes AP- CSI. It can be seen that this implementation manner is beneficial for the network device to obtain the channel state information contained in the first uplink control channel bearer information, or the channel state information contained except for the P-CSI on the resources corresponding to the rate matching.

In a seventh aspect, the present application also provides a channel transmission method, which is similar to the above-mentioned sixth aspect. It is explained from the perspective of the network equipment side, such as TRP1, and the resources occupied by the first uplink control channel and the first uplink The resources occupied by the shared channels overlap, and the first uplink control channel is associated with the first uplink shared channel. The difference between this channel transmission method and the channel transmission method described in the sixth aspect is that the network device can detect the first uplink control channel once instead of detecting the information carried by the first uplink control channel twice, which is beneficial Reduce the processing burden of network equipment, as explained below.

In the channel transmission method, the network device determines that the first uplink control channel is associated with the first uplink shared channel, and the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel; The device receives one of the first uplink control channel and the first uplink shared channel.

Resources overlap; the network device receives one of the first uplink control channel and the first uplink shared channel.

For example, the network device receives the first uplink control channel, but does not receive the first uplink shared channel, and the timing condition between the first uplink shared channel and the first uplink control channel is not satisfied; or, the network device receives the The first uplink shared channel does not receive the first uplink shared channel, and obtains part or all of the information carried by the first uplink control channel from the first uplink shared channel, and, the first Information carried by the uplink shared channel, where a timing condition is satisfied between the first uplink shared channel and the first uplink control channel.

In an optional implementation manner, the HARQ-ACK included in the first uplink control channel bearer information is in a manner of puncturing the resources occupied by the first uplink shared channel, and the first uplink shared channel The information carried by an uplink shared channel is multiplexed and carried on the first uplink shared channel, wherein the number of HARQ-ACK bits contained in the information carried by the first uplink control channel is less than or equal to the second preset Threshold; or, the HARQ-ACK contained in the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel in a rate matching manner, and is carried on the first uplink On the shared channel, wherein the number of HARQ-ACK bits included in the first uplink control channel bearer information is greater than the second preset threshold.

The applicable scenarios of the embodiments of the present application may be extremely high reliability and low latency (Ultra-Reliable and Low-Latency Communications, URLLC) scenarios or Enhanced Mobile Broadband (eMBB) scenarios. Among them, in the URLLC scenario, only one uplink shared channel, such as one PUSCH, is allowed to be sent in a time unit. In the eMBB scenario, two uplink control channels and one uplink shared channel can be allowed in the same time unit, and both uplink control channels can carry HARQ-ACK. The time unit may be a time slot or a mini-slot.

In another aspect, the channel transmission method may include: once the resources occupied by multiple uplink channels overlap, the terminal may not transmit all the overlapping uplink channels, that is, as long as the resources occupied by the uplink channels overlap, discard All overlapping upstream channels.

In yet another aspect, the channel transmission method may include: overlapping resources occupied by multiple uplink channels, sending the uplink shared channel first and discarding the uplink control channel; or sending the uplink control channel first and discarding the uplink shared channel.

In another aspect, the present application also provides a channel transmission method. When the resources occupied by multiple uplink channels overlap, the associated uplink channels can be multiplexed using the method described in the third aspect; secondly, For the multiplexed uplink channel, the associated uplink channel that cannot be multiplexed, and the unassociated uplink channel, according to the starting position of each uplink channel and the symbol length occupied, it can determine which uplink channels to send and which ones to not send Uplink channel.

Among them, under the LTE system proposed by the 3rd generation partnership project (the 3rd generation partnership project, 3GPP), the vehicle to everything (V2X) technology (X stands for anything) for communication between cars and everything is proposed.

To facilitate understanding of the embodiments of the present application, the communication system shown in FIG. 2 is taken as an example for illustration. Please refer to FIG. 2. FIG. 2 is a schematic diagram of a multi-transmission receiving point TRP cooperative transmission provided by an embodiment of the present application. FIG. 2 uses the network devices TRP1 and TRP2, both of which can communicate with the terminal, as an example.

With the rapid development of mobile communications, coordinated multipoint transmission technology can improve system performance, especially the spectrum efficiency at the cell edge. As shown in Figure 2, the terminal can determine the physical uplink control channel (PUCCH) 1 and physical uplink shared channel (PUSCH) 1 corresponding to TRP1, and PUCCH2 corresponding to TRP2; further, the terminal needs Send Physical Uplink Control Channel (PUCCH) 1 and Physical Uplink Shared Channel (PUSCH) 1 to TRP1 respectively; send PUCCH2 to TRP2. Once the resources occupied by multiple uplink channels overlap, such as the above PUSCH1 overlaps PUCCH1 and PUCCH2, how the terminal transmits these uplink channels so that the network equipment can obtain the uplink control information carried by the uplink channel sent by the terminal becomes an urgent problem to be solved problem.

Therefore, in order to solve the above problem, the present application provides a channel transmission method, which can transmit at least one uplink channel of the multiple uplink channels when the resources occupied by multiple uplink channels overlap, which is beneficial to the network equipment to obtain the information sent by the terminal. The uplink control information carried by the uplink channel.

To facilitate the understanding of the embodiments of the present application, a few related concepts are briefly introduced first.

In the embodiment of the present application, the overlap of resources occupied by multiple uplink channels may include overlaps in time domain resources, frequency domain resources, or time-frequency domain resources.

Among them, time domain resources can refer to subframes, time slots, radio frames, mini slots or sub slots, multiple aggregated time slots, and multiple aggregated time slots. Subframes, symbols, etc., may also refer to Transmission Time Interval (TTI). Among them, one or more time units can be included in the time domain, one time unit can include an integer number of another time unit, or the duration of a time unit in the time domain is equal to an integer number of another time unit. The duration in the domain, for example, a mini-slot/slot/subframe/radio frame contains an integer number of symbols, a slot/subframe/radio frame contains an integer number of mini-slots, and a subframe/radio frame contains An integer number of time slots, a radio frame includes an integer number of subframes, etc., and other including examples may also exist, which are not limited in this application.

Among them, frequency domain resources include subcarriers, resource blocks (resource blocks, RB), physical resource blocks, virtual resource blocks, precoding resource block groups (PRG), and physical resource block groups (physical resource block groups, RBG), subband (subband), partial bandwidth (partial bandwidth), bandwidth part (BWP), carrier (carrier), serving cell (serving cell), frequency band (band), etc.

Wherein, the time-frequency resources include frequency-domain resources corresponding to certain time-domain resources.

In the embodiment of the present application, the overlap of resources occupied by multiple uplink channels may be in a period of time domain unit (also called time unit), or a period of frequency domain unit, or a period of time-frequency unit, the multiple uplink channels occupy Some or all of the resources overlap. For example, the overlap of resources occupied by multiple uplink channels may be the overlap of resources occupied by multiple uplink channels in a time slot or a symbol; or, on a subcarrier or resource block, the resources occupied by multiple uplink channels may be overlapped. Account for the overlap of resources. Correspondingly, this application takes the overlap of resources occupied by at least two uplink channels among the first uplink control channel, the second uplink control channel, and the first uplink shared channel as an example to illustrate the channel transmission method of the terminal or the network device. The "first" and "second" in this do not refer to number or order.

In the embodiments of the present application, the resources occupied by multiple uplink channels overlap, which may also be referred to as the overlap of resources occupied by multiple uplink channels, or multiple uplink channel conflicts, or multiple uplink channel transmission conflicts, etc. , The embodiment of this application does not limit it.

In the embodiment of the present application, the uplink channel may be a collective term for the uplink control channel and the uplink shared channel, that is, the uplink channel may be an uplink control channel or an uplink shared channel unless otherwise specified. Among them, the uplink control channel may include the physical uplink control channel (PUCCH), the enhanced physical uplink control channel EPUCCH (Enhanced Physical Uplink Control Channel, EPUCCH); the uplink shared channel may include the physical uplink shared channel (Physical Uplink Share Channel, PUSCH).

The "associated uplink channel" described in the embodiments of this application may be the resource occupied by the associated uplink control channel and the resource occupied by the uplink shared channel; the unassociated uplink channel may be the resource occupied by the unassociated uplink control channel Share the resources occupied by the channel with the uplink. The uplink control channel is associated with the uplink shared channel, which means that the uplink control channel and the uplink shared channel are sent to the same network device; correspondingly, the resources occupied by the uplink control channel are not related to the resources occupied by the uplink shared channel. It means that the uplink control channel and the uplink shared channel are respectively sent to different network devices.

In the embodiment of the present application, whether the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel are associated can be determined by whether the respective downlink control related parameters corresponding to each channel are the same.

In an optional implementation manner, if the uplink control channel contains Hybrid Automatic Repeat request (HARQ)-acknowledgement information (ACK), then the downlink control related parameter corresponding to the uplink control channel is scheduling The data channel corresponding to the HARQ-ACK, such as the downlink control parameters of the DCI of the physical downlink shared channel (Physical Downlink Share Channel, PDSCH); the downlink control parameter corresponding to the uplink shared channel is the downlink of the DCI scheduling the uplink shared channel Control related parameters, so that whether the resources occupied by the uplink control channel are related to the resources occupied by the uplink shared channel can be determined according to whether the two downlink control related parameters are the same. For example, the HARQ-ACK carried by the PUCCH is fed back for the data carried in the PDSCH, then the downlink control related parameter corresponding to the PUCCH is the downlink control related parameter of the DCI1 scheduling the PDSCH; correspondingly, the downlink control related parameter corresponding to the PUSCH is The downlink control related parameters of the DCI2 of the PUSCH are scheduled. Therefore, when the downlink control related parameters of the DCI1 and the downlink control related parameters of the DCI2 are the same, the PUCCH is associated with the PUSCH.

In another optional implementation manner, if the uplink control channel does not include HARQ-ACK, the downlink control related parameters corresponding to the uplink control channel are the downlink control parameters carried in the configuration information of the channel state information carried by the uplink control channel. Control related parameters; thereby, whether the uplink control channel is associated with the uplink shared channel can be determined based on whether the downlink control related parameter is the same as the downlink control related parameter in the DCI for scheduling the uplink shared channel. For example, PUCCH does not contain HARQ-ACK but contains channel state information, then the downlink control related parameters corresponding to PUCCH are the downlink control related parameters carried in the configuration information of the channel state information; correspondingly, when the channel state information is configured The downlink control related parameters carried in the information are the same as the downlink control related parameters in the DCI2 that schedules the PUSCH, then the PUCCH is associated with the PUSCH.

Among them, downlink control related parameters may include physical downlink control channel configuration parameters (Physical Downlink Control Channel Config, PDCCH-Config), control resource set configuration parameters (Control Resource Sets, CORESET), or control resource set configuration parameter group (Control Resource Sets group) , CORESET group) and so on. The parameters included in the PDCCH-Config are used to detect candidate downlink control channels (Physical Downlink Control Channel, PDCCH). CORESET can be called the control resource set, that is, the time-frequency resources of CORESET, such as the resource block size occupied by the frequency domain, the number of symbols occupied by the time domain, etc.; CORESET refers to the relevant parameters of the signaling configuration, used to obtain the CORESET time-frequency resources . The CORESET group may include one or more control resource set configuration parameters or index numbers of control resource set configuration parameters, where one control resource set configuration parameter may be represented by an index number or an identifier. When a CORESET group contains a CORESET, the logo of the CORESET group can be used as the logo of CORESET, or the logo of CORESET can be used as the logo of CORESET group. Other downlink control channel configuration parameters are similar.

In the embodiment of the present application, the hybrid automatic repeat request confirmation information is used to give positive (ACK) or negative (NACK) feedback to received data, such as data carried by PDSCH, so that lost or erroneous data can be quickly reproduced. pass. In the embodiments of the present application, the HARQ-ACK described does not only refer to positive feedback, but refers to all feedback of data carried by the corresponding PDSCH. For the convenience of explanation, this article simply describes the hybrid automatic repeat request confirmation message as HARQ-ACK.

In the embodiment of this application, regarding the association between the uplink control channel and the uplink shared channel, if the information carried on the uplink control channel needs to be multiplexed with the information carried on the uplink shared channel, and carried on the uplink shared channel, the uplink shared channel is associated with the uplink shared channel. A certain time delay must be met between the control channels, or a timing condition must be met between the uplink control channel and the uplink shared channel. This timing condition may also be referred to as a time delay relationship or multiplexing timing condition, that is, the terminal needs to have the ability to report the downlink shared channel prepared by itself. In other words, the data information, CSI information, and multiplexed information carried by the downlink shared channel need to be considered. For example, when transmitting the uplink shared channel, it is necessary to consider the processing delay of the downlink shared channel and its corresponding demodulation parameter signal (Demodulation Reference Signal, DMRS) according to the capabilities of the terminal; when there is aperiodic CSI, CSI also needs to be considered The processing delay of the uplink shared channel and its corresponding DMRS should be considered according to the terminal’s capabilities. Therefore, if part or all of the information carried by the uplink control channel is multiplexed with the information carried by the uplink shared channel and carried on the uplink shared channel for transmission, the uplink shared channels need to meet the above processing delay.

In the embodiments of this application, "multiplexing" has two situations. The first type of multiplexing refers to the fact that the uplink control channel is associated with the uplink shared channel and the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel. The information carried by the uplink control channel is multiplexed with the information carried by the uplink shared channel, and carried on the uplink shared channel for transmission; the second type of multiplexing refers to the fact that the uplink control channel and the uplink shared channel are not associated and the uplink control channel The occupied resources overlap with the resources occupied by the uplink shared channel, and the resources occupied by the uplink shared channel overlap with the resources occupied by the uplink control channel by puncturing to transmit the uplink control channel and the uplink shared channel at the same time.

Part or all of the information carried by the uplink control channel is multiplexed with the information carried by the uplink shared channel in a puncturing manner. When the network device receives the uplink shared channel, it can obtain punctured but not transmitted data through error correction. Similarly, for the second case of puncturing, the network device can also obtain data that has not been transmitted due to the resource being punctured through error correction.

The "punching" in the above two cases of multiplexing means that on the terminal side, a part of the resources occupied by the uplink shared channel is removed, and the data that should be placed in this part of the resource is also skipped or not transmitted. , But from the network equipment side, it is also believed that the resources occupied by the uplink shared channel are not missing, so skipped or untransmitted data can be obtained through error correction.

The difference between the "punching" in the above two cases of multiplexing is that in the first case, the position of the puncturing is not necessarily the resource position where the resources occupied by the two uplink channels overlap, while in the second case, The puncturing position must be the resource position where the resources occupied by the two uplink channels overlap. In addition, the rate matching in the first case of multiplexing means that on the terminal side, a part of the resources occupied by the uplink shared channel is removed, and the data that should be placed in this part of the resource is also skipped or not transmitted. From the network equipment side, it is also known that the resources occupied by the uplink shared channel are missing this part of the resources.

In an optional implementation manner, for the precondition of "multiplexing" in the second case, whether the resources occupied by the uplink control channel overlap with the resources occupied by the DMRS corresponding to the uplink shared channel and whether the uplink control channel In the total number of bits carrying information. Since the "multiplexing" in this case is to punch holes in the resources occupied by the uplink shared channel which overlaps the resources occupied by the uplink control channel, it may cause the loss of DMRS or the network side cannot receive DMRS, which affects Channel estimation, which in turn causes the entire uplink shared channel to fail to receive successfully. Therefore, when the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel do not overlap and the total number of bits of information carried by the uplink control channel is less than the first preset threshold, the "multiplexing" is necessary. Ways to send uplink shared channel and uplink control channel.

In another optional implementation manner, in view of the precondition of "multiplexing" in the second case above, the transmission of resources overlapping between the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel may also be considered. Whether the power exceeds the maximum transmission power, if it exceeds the maximum transmission power, then “multiplexing” is no longer considered, and only one channel is selected for transmission; if the maximum transmission power is not exceeded, the preconditions in the above implementation can be further considered. That is, whether the resources occupied by the uplink control channel overlap with the resources occupied by the DMRS corresponding to the uplink shared channel. In this way, after the uplink shared channel is punctured, the transmission power is too small, resulting in failure to receive.

In the embodiments of the present application, the information carried by the uplink control channel may be referred to as uplink control information (Uplink Control Information, UCI), and the UCI carried on the uplink control channel may include one or more of HARQ-ACK and channel state information. Among them, the channel state information carried on the uplink control channel may include periodic channel state information (P-CSI), semi-static channel state information (semi-CSI), etc. The information carried by the uplink shared channel may include one or more of UCI and data information. Among them, the UCI carried on the uplink shared channel may include semi-static channel state information (semi-CSI) and aperiodic channel state information (AP-CSI). Among them, the semi-static channel state information (semi-CSI) is configured to be transmitted on which of the uplink control channel and the uplink shared channel, and the UCI information carried by which channel may include the semi-CSI. When the information carried by the uplink control channel is multiplexed with the information carried by the associated uplink shared channel and is carried on the uplink shared channel for transmission, the UCI carried by the uplink shared channel may also include HARQ-ACK. In summary, the information or UCI carried by the uplink control channel may include HARQ-UCI; the information carried by the uplink shared channel may include UCI and data information, where UCI may include channel state information, and when the information carried by the uplink control channel When multiplexed with information carried by the uplink shared channel and carried on the uplink shared channel, the UCI carried by the uplink shared channel may also include HARQ-ACK.

In an optional implementation manner, the priority between AP-CSI, P-CSI, semi-CSI carried on the uplink shared channel, and semi-CSI carried on the uplink control channel can be: "AP -The priority of CSI is higher than the priority of semi-CSI carried on the uplink shared channel; the priority of semi-CSI carried on the uplink shared channel is higher than the semi-CSI carried on the uplink control channel -CSI priority"; "The priority of semi-CSI carried on the uplink control channel" is higher than the "Priority of P-CSI". In another optional implementation manner, the priority of each channel state information described above may also be predefined or configured accordingly according to application scenarios. The embodiments of this application do not make limitations.

In the embodiment of this application, the priority of the information carried by the uplink shared channel is determined by the highest priority among the information carried by the uplink shared channel; the priority of the information carried by the uplink control channel is the priority of the information carried by the uplink control channel The highest priority is determined. For example, if the priority of HARQ-ACK is higher than the priority of channel state information, the priority of information carried by the uplink shared channel is determined by whether the uplink shared channel carries the HARQ-ACK information. If HARQ-ACK is used, the uplink shared channel has the highest priority; if it does not carry HARQ-ACK, the uplink shared channel has a relatively low priority; the priority of the uplink control channel information is determined by Whether the uplink control channel carries the hybrid automatic repeat request confirmation information HARQ-ACK is determined. If it carries HARQ-ACK, the priority of the uplink control channel carrying information is the highest; if it does not carry HARQ-ACK, the uplink control The priority of the channel carrying information is relatively low.

Based on the above related elaboration, the channel transmission method of the present application can transmit at least one uplink channel when the resources occupied by multiple uplink channels overlap in the multipoint transmission scenario, so that the corresponding network equipment can obtain the transmitted uplink channel bearer in time. Information. Several optional embodiments are summarized below. In addition, in each embodiment, there are two uplink control channels that may carry HARQ-ACK, a second uplink control channel, and an uplink shared channel in one time unit. The channel is associated with the uplink shared channel, the second uplink control channel is not associated with the other two channels, and the resources occupied by the uplink control channel and the resources occupied by the uplink shared channel need to be sent to TRP1, and the second uplink control channel is Take the example that needs to be sent to TRP2, and describe the channel transmission method in conjunction with the communication system shown in Figure 2.

As shown in Figure 3a, in a time unit, when the terminal device determines that the resources occupied by the first uplink control channel, the resources occupied by the second uplink control channel, and the resources occupied by the first uplink shared channel do not overlap each other, the terminal The three uplink channels are sent separately, and accordingly, TRP1 can receive the first uplink control channel and the first uplink shared channel, and TRP2 can receive the second uplink control channel.

As shown in Figure 3b, the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, and the resources occupied by the second uplink control channel do not overlap with the resources occupied by the other two uplink channels. ; As shown in Figure 3c, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, the resources occupied by the first uplink control channel and the resources occupied by the other two uplink channels are not Overlap; as shown in Figure 3d, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel; and as shown in Figure 3e, the first The resources occupied by the uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel. The following describes the channel transmission method in the way that the terminal interacts with TRP1 and TRP2 for the overlap shown in FIG. 3b to FIG. 3e. Wherein, when resources occupied by multiple uplink channels overlap, the uplink channel that the terminal does not send may also be referred to as the terminal discarding the uplink channel (that is, dropping the uplink channel).

1. The channel transmission method when the resource occupied by the associated uplink control channel overlaps the resource occupied by the uplink shared channel

In this embodiment, when the resource occupied by the associated uplink control channel overlaps the resource occupied by the uplink shared channel, the terminal sends one of the uplink shared channel and the uplink control channel.

In an optional implementation manner, the terminal multiplexes the information carried by the uplink control channel with the information carried by the uplink shared channel, and carries the information on the uplink shared channel, and further, the terminal may send the uplink Shared channel, the uplink control channel is not sent. Wherein, if a timing condition is satisfied between the uplink control channel and the uplink shared channel, this implementation manner can be executed. Specifically, how to determine whether the time sequence condition is satisfied can be determined in conjunction with the above-mentioned related concept description part, and will not be described in detail here.

In another optional implementation manner, the terminal does not send the uplink shared channel, but sends the uplink control channel. Wherein, when the time sequence condition is not satisfied between the uplink control channel and the uplink shared channel, this implementation manner can be performed.

Wherein, the terminal multiplexing the information carried by the uplink control channel and the information carried by the uplink shared channel may be multiplexing in a puncturing or rate matching manner.

In an example, the terminal uses a method of puncturing the resources of the uplink shared channel to multiplex the HARQ-ACK included in the uplink control channel carrying information with the information carried by the uplink shared channel; wherein, If the number of HARQ-ACK bits included in the uplink control channel bearer information is less than or equal to the second preset threshold, the multiplexing mode described in this example can be performed. In another example, the terminal uses a rate matching method to multiplex the HARQ-ACK contained in the uplink control bearer information with the information carried by the uplink shared channel; wherein, the uplink control bearer information When the number of HARQ-ACK bits included is greater than the second preset threshold, the multiplexing mode described in this example can be performed.

In another example, the terminal multiplexes the channel state information contained in the uplink control channel carrying information with the information carried by the uplink shared channel in a rate matching manner; wherein, the uplink shared channel carries The channel state information is not included in the information, and the method of this example can be performed.

In another example, when the uplink control channel contains channel state information and the uplink shared channel also contains channel state information, the terminal may discard the CSI information contained in the uplink control channel. That is, in this case, it is wrong. The channel state information carried by the uplink control channel is multiplexed. In another example, the terminal combines the channel state information contained in the uplink control channel bearer information with the channel state information carried by the uplink shared channel, except for the periodic channel state information P-CSI, in a rate matching manner. Information multiplexing; where the information carried by the uplink shared channel contains channel state information, and the method of this example can be implemented.

The first preset threshold may be a preset number of HARQ-ACK bits. The first preset threshold may be 2 bits or 4 bits, etc. The first preset threshold can be configured according to requirements.

For example, the information carried by the uplink control channel includes HARQ-ACK and P-CSI, and when there is no AP-CSI in the uplink shared channel, HARQ-ACK and P-CSI can be multiplexed with the information carried by the uplink shared channel, and Send on the uplink shared channel. For another example, when the uplink control information includes HARQ-ACK and P-CSI, and when the uplink shared channel includes AP-CSI, the terminal can discard the P-CSI and multiplex the HARQ-ACK with the information carried by the uplink shared channel. And sent on the uplink shared channel.

For the network device side, the associated uplink control channel and uplink shared channel can be sent to the same network device. In an optional implementation manner, the network device receives the uplink control channel on the resources of the uplink control channel; the network device receives the uplink control channel on the resources of the uplink shared channel when the uplink control channel is not received. The uplink shared channel; and, the network device obtains part or all of the information carried by the uplink control channel from the received uplink shared channel, and obtains the information carried by the uplink shared channel; and the uplink control The channel is associated with the uplink shared channel. It can be seen that the network equipment can detect the information carried by the uplink control channel twice, that is, on the resources of the uplink control channel. If not, it can detect part or all of the information carried by the uplink control channel on the resources of the uplink shared channel. Therefore, this implementation manner is beneficial to obtain more uplink control information through direct detection when resources occupied by multiple uplink channels overlap. Correspondingly, how the network equipment detects part or all of the information carried by the uplink control channel from the uplink shared channel can be determined by referring to the multiplexing related content in this article.

In another optional implementation manner, the network device can learn that the resources occupied by the uplink control channel overlap the resources occupied by the uplink shared channel, the network device determines that the uplink control channel is associated with the uplink shared channel, and the The resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel; the network device receives one of the uplink control channel and the uplink shared channel. For example, if a timing condition is satisfied between the uplink shared channel and the uplink control channel, the network device receives the uplink shared channel but does not receive the uplink control channel. For another example, if a timing condition is not satisfied between the uplink shared channel and the uplink control channel, the network device does not receive the uplink shared channel, but receives the uplink control channel. It can be seen that in this embodiment, the network device can detect the uplink control channel once, instead of detecting the information carried by the uplink control channel twice, which is beneficial to reducing the processing burden of the network device. Correspondingly, how the network equipment detects part or all of the information carried by the uplink control channel from the uplink shared channel can be determined by referring to the multiplexing related content in this article.

As shown in Figure 3b, the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, and the resources occupied by the second uplink control channel do not overlap with the resources occupied by other uplink channels, so the terminal can Send the second uplink control channel, TRP2 can receive the second uplink control channel. Referring to FIG. 4, for the first uplink control channel and the first uplink shared channel, the channel transmission method may include the following steps:

101. The terminal determines that the resource occupied by the first uplink control channel overlaps the resource occupied by the first uplink shared channel, and the first uplink shared channel is associated with the first uplink control channel.

Specifically, it is determined whether the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel, or whether the first uplink shared channel is associated with the first uplink control channel, please refer to "overlap" in this article Or "association" to determine the relevant content, which will not be detailed here.

102. The terminal judges whether the time sequence condition between the first uplink control channel and the first uplink shared channel is met, if the time sequence condition is met, step 103 is executed; if the time sequence condition is not met, step 104 is executed;

103. The terminal multiplexes part or all of the information carried by the uplink control channel with the information carried by the uplink shared channel in a puncturing or rate matching manner, and carries it on the first uplink shared channel, and sends the first uplink shared channel without sending First uplink control channel; TRP1 can receive the first uplink shared channel, and obtain part or all of the information carried by the first uplink control channel and the information carried by the first uplink shared channel from the first uplink shared channel.

104. The terminal sends the first uplink control channel, but does not send the first uplink shared channel; TRP1 receives the first uplink control channel, but does not receive the first uplink shared channel.

It can be seen that the channel transmission method can multiplex part or all of the information carried by the first uplink control channel, that is, the UCI information, in a timely manner when the first uplink control channel and the first uplink shared channel meet the timing conditions. Send on the first uplink shared channel, so that TRP1 can obtain UCI information in time; even if the two do not meet the timing conditions, the first uplink control channel can be sent first, so that TRP1 can obtain the UCI information carried by the first uplink control channel in time .

2. Channel transmission method when the resources occupied by the non-associated uplink control channel overlap with the resources occupied by the uplink shared channel

In this embodiment, the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel, and the uplink control channel is not associated with the uplink shared channel, and the terminal transmits at least one of the uplink shared channel and the uplink control channel.

In an optional implementation manner, when the precondition of "multiplexing" in the second case above is met and the total number of bits of information carried by the uplink control channel is less than or equal to the first preset threshold, the uplink shared channel can be used In the occupied resources, the resources occupied by the uplink shared channel and the resources occupied by the uplink control channel are punctured, and the uplink control channel and the uplink shared channel are sent; when the above-mentioned second condition "reuse" is not met Condition or that the total number of bits of information carried by the uplink control channel is greater than a first preset threshold, and the terminal sends one of the uplink shared channel and the uplink control channel. Correspondingly, since the resources occupied by the non-associated uplink control channel and the uplink shared channel are sent to different network devices, each network device can only receive its own uplink control channel and uplink shared channel. If it is not received, it means the reception failed.

The first preset threshold may be a preset total number of bits of information carried by the uplink control channel. The first preset threshold may be 2 bits or 4 bits, etc.

In an optional implementation manner, the terminal transmits one of the uplink shared channel and the uplink control channel. In an alternative implementation manner, the terminal does not send the uplink shared channel but sends the uplink control channel; or, the terminal sends the uplink shared channel but does not send the uplink control channel. Wherein, the information carried by the uplink control channel includes hybrid automatic repeat request acknowledgement information HARQ-ACK, the terminal does not send the uplink shared channel, but sends the uplink control channel; the information carried by the uplink control channel Without HARQ-ACK, the terminal sends the uplink shared channel, but does not send the uplink control channel. It can be seen that, in this embodiment, on the one hand, it is beneficial for the terminal to preferentially send HARQ-ACK to the network device, and on the other hand, it is beneficial for the terminal to preferentially transmit UCI information and/or data carried by the uplink shared channel to the network device.

For example, as shown in Figure 3c, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink control channel do not overlap with the resources occupied by other uplink channels. The terminal can directly send the first uplink control channel. Regarding the first uplink shared channel and the second uplink control channel, referring to FIG. 5, the channel transmission method may include the following steps:

201. The terminal determines that the resource occupied by the first uplink shared channel overlaps the resource occupied by the second uplink control channel, and the second uplink control channel is not associated with the first uplink shared channel;

202. The terminal judges whether the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel overlap, and whether the total number of bits of information carried by the uplink control channel is less than or equal to the first preset threshold; When the occupied resources and the resources occupied by the DMRS corresponding to the uplink shared channel do not overlap, and the total number of bits of information carried by the second uplink control channel is less than or equal to the first preset threshold, step 203 is performed; if the uplink control channel is occupied When the resource overlaps with the resource occupied by the DMRS corresponding to the uplink shared channel, or the total number of bits of information carried by the uplink control channel is greater than the first preset threshold, perform step 204;

203. The terminal transmits the first uplink shared channel and the second uplink control channel by puncturing the resources occupied by the first uplink shared channel; TRP1 receives the first uplink shared channel, and TRP2 receives the second uplink Control channel

204. The terminal judges whether HARQ-ACK is included in the information carried by the second uplink control channel; if it does, execute step 205; if it does not include it, execute step 206;

205. The terminal does not send the first uplink shared channel but sends the second uplink control channel; TRP1 cannot receive the first uplink shared channel; TRP2 receives the second uplink control channel;

206. The terminal does not send the second uplink control channel, but sends the first uplink shared channel; TRP1 is the first uplink shared channel, and TRP2 cannot receive the second uplink control channel.

It can be seen that in this embodiment, when the resources occupied by the non-associated uplink shared channel overlap with the resources occupied by the uplink control channel, the above-mentioned second condition is "multiplexed" and the total number of bits of the uplink control channel carrying information is less than When it is equal to or equal to the first preset threshold, the uplink shared channel and the uplink control channel can be sent separately; and when the above second condition is not met, "multiplexing" or the total number of bits of uplink control channel carrying information is greater than the first preset threshold At this time, if the uplink control channel includes HARQ-ACK, the uplink control channel can be sent instead of the uplink shared channel; thus, it is beneficial to send the HARQ-ACK to the network device in time. Correspondingly, if the uplink control channel does not contain HARQ-ACK, the uplink shared channel can be sent instead of the uplink control channel; thus, it is beneficial to send the data and/or channel state information carried by the uplink shared channel to the network device .

3. The channel transmission method when the resources occupied by the associated uplink channels overlap, and the resources occupied by the unassociated uplink channels also overlap

In this application, when the resources occupied by the associated uplink channels overlap, and the resources occupied by the unassociated uplink channels also overlap, the terminal can combine the above-mentioned embodiments in the case of overlaps 1 and 2 to finally determine which uplink channel to send, not Which uplink channel to send, or to send all uplink channels.

In an optional embodiment, the terminal may first determine the transmission mode of the associated uplink channel by using the embodiment described in 1 above for the associated uplink channel, and then further determine the non-associated uplink channel in combination with the embodiment described in 2 above. How the channel is sent.

For example, the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel. The terminal determines to send the first uplink control channel according to the embodiment described in 1 above. , When the first uplink shared channel is not sent, the terminal can directly send the second uplink control channel without performing the operations in the above-mentioned embodiment 2; when the terminal determines not to send the first uplink control channel according to the above-mentioned embodiment 1 If the first uplink shared channel is sent, the terminal needs to combine the steps in the above-mentioned embodiment 2 to send at least one of the first uplink shared channel and the second uplink control channel.

As in the channel transmission method described in 2 above, the resources occupied by the second uplink control channel and the resources occupied by the demodulation reference signal (DMRS) corresponding to the first uplink shared channel do not overlap, and The total number of bits of information carried by the second uplink control channel is less than or equal to the first preset threshold, and the terminal transmits the first uplink shared channel by puncturing the resources occupied by the first uplink shared channel And the second uplink control channel. The resources occupied by the second uplink control channel overlap with the resources occupied by the demodulation reference signal corresponding to the first uplink shared channel, or the total number of bits of information carried by the second uplink control channel is greater than that of the first uplink shared channel. For a preset threshold, the terminal sends one of the first uplink shared channel and the second uplink control channel.

Wherein, in this embodiment, the priority of the information carried by the first uplink shared channel is lower than or equal to the priority of the information carried by the second uplink control channel, and the terminal does not send the first uplink shared channel, and sends the The second uplink control channel; or, the priority of the information carried by the first uplink shared channel is greater than the priority of the information carried by the second uplink control channel, and the terminal sends the first uplink shared channel without sending the The second uplink control channel.

For another example, the priority between AP-CSI, P-CSI, semi-CSI carried on the first uplink shared channel and semi-CSI carried on the first uplink control channel can be: "AP-CSI "Priority" is higher than "the priority of semi-CSI carried on the uplink shared channel"; "the priority of semi-CSI carried on the uplink shared channel" is higher than "the priority of semi-CSI carried on the uplink control channel" Priority"; "The priority of semi-CSI carried on the uplink control channel" is higher than the "Priority of P-CSI". Therefore, when the information carried by the first uplink control channel is multiplexed with the information carried by the first uplink shared channel, the P-CSI in the first uplink control bearer information may not be multiplexed, that is, the P-CSI may be discarded so as to change the priority. When the higher UCI is sent to the network device, the resource occupation ratio of the first uplink shared channel by the multiplexing method is reduced.

For example, as shown in Figure 3d, the resources occupied by the first uplink shared channel overlap with the resources occupied by the second uplink control channel, and the resources occupied by the first uplink control channel overlap with the resources occupied by the first uplink shared channel. Please refer to Figure 6, the channel transmission method may include the following steps:

301. The terminal determines that the resource occupied by the first uplink shared channel overlaps the resource occupied by the second uplink control channel and the resource occupied by the first uplink control channel, and the first uplink shared channel is associated with the first uplink control channel;

302. The terminal judges whether a timing condition is satisfied between the first uplink control channel and the first uplink shared channel, and if the timing condition is satisfied, steps 303 to 304 are executed; if the timing condition is not satisfied, step 308 is executed;

303. The terminal multiplexes part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel in a puncturing or rate matching manner, and carries it on the first uplink shared channel;

304. The terminal determines whether the resource occupied by the second uplink control channel overlaps with the resource occupied by the DMRS corresponding to the first uplink shared channel, and whether the total number of bits of information carried by the second uplink control channel is less than or equal to the first preset threshold ; If the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel do not overlap, and the total number of bits of information carried by the second uplink control channel is less than or equal to the first preset threshold, execute Step 307: If the resources occupied by the second uplink control channel overlap with the resources occupied by the DMRS corresponding to the first uplink shared channel, or the total number of bits of information carried by the second uplink control channel is greater than the first preset When the threshold is reached, go to step 305;

305. The terminal judges whether the priority of the information carried by the first uplink shared channel is lower than or equal to the priority of the information carried by the second uplink control channel; if the priority of the information carried by the first uplink shared channel is lower than or Is equal to the priority of the information carried by the second uplink control channel, go to 308; if the priority of the information carried by the first uplink shared channel is higher than the priority of the information carried by the second uplink control channel, go to 306;

306. The terminal sends the first uplink shared channel, but does not send the first uplink control channel and the second uplink control channel.

307. The terminal transmits the first uplink shared channel and the second uplink control channel by puncturing the resources occupied by the first uplink shared channel, and does not transmit the first uplink control channel;

308. The terminal sends the first uplink control channel and the second uplink control channel, but does not send the first uplink shared channel.

In another alternative embodiment, the terminal may first use the embodiment described in 2 above for the unassociated uplink channel to determine how to transmit the unassociated uplink channel; then combine with the embodiment described in 1 above to further determine the remaining Transmission method of overlapping uplink channels.

For example, as shown in Figure 3d, the uplink shared channel overlaps the uplink control channel and the second uplink control channel. The terminal determines to send the second uplink control channel according to the embodiment described in 2 above. When the uplink shared channel is not sent, the terminal can Send the uplink control channel and the second uplink control channel directly without performing the operations in the above-mentioned embodiment 1; when the terminal determines not to send the second uplink control channel and the uplink shared channel according to the above-mentioned embodiment 2 The terminal also needs to combine the steps in the embodiment described in 1 above to send one of the uplink shared channel and the uplink control channel; when the terminal determines to send the second uplink control channel and the uplink shared channel according to the embodiment described in 2 above, then The terminal also needs to combine the steps in the embodiment described in 1 above to send one of the uplink shared channel and the uplink control channel, and the second uplink control channel.

4. A channel transmission method when the resources occupied by multiple uplink channels overlap

In this channel transmission method, when the resources occupied by multiple uplink channels overlap, the uplink channels that meet the prerequisite of "multiplexing" in the first case can be multiplexed for the overlapping associated uplink channels; After used uplink channels, associated uplink channels that cannot be reused, and unassociated uplink channels, which uplink channels are sent and which uplink channels are not sent can be determined according to the starting position of each uplink channel and the symbol length occupied. Or, it is possible to multiplex the overlapping unassociated uplink channels first, and the uplink channels that meet the prerequisite of "multiplexing" in the second case; secondly, for the multiplexed uplink channels, the unassociated uplink channels that cannot be reused The uplink channel and the associated uplink channel can determine which uplink channels are sent and which uplink channels are not to be sent according to the starting position of each uplink channel and the symbol length occupied. Or, when the resources occupied by multiple uplink channels overlap, the transmission scheme of the multiple uplink channels can be determined simply based on the starting position of each uplink channel and the symbol length occupied.

For example, for multiple uplink channels with overlapping resources, first determine the uplink channel with the start symbol position earlier or the front, and then determine the longest symbol from the uplink channel with the start symbol position earlier or the front. The uplink channel is to send the uplink channel with the longest symbol, and not to send other uplink channels that overlap the resources occupied by the uplink channel with the longest symbol; and then for the remaining multiple resources that overlap Uplink channel, execute the above method.

For another example, the associated PUCCH1 and PUSCH1 are multiplexed as described above, and the multiplexed PUSCH1 and the unassociated PUCCH2 are also overlapped, then the position of the starting symbol can be determined from the multiplexed PUSCH1 and the unassociated PUCCH2. If the previous or foremost uplink channel is the multiplexed PUSCH1, the terminal transmits the multiplexed PUSCH1, and will not transmit the PUCCH2 that overlaps it. For another example, as shown in FIG. 3d, the upstream channel that transmits the start symbol earlier or first is the first upstream control channel. Therefore, the terminal may only transmit the first upstream control channel, and not the first upstream shared channel and the first upstream shared channel. 2. Uplink control channel.

For another example, if the start positions of multiple overlapping uplink channels are the same, the uplink channel with the longest symbol can be determined, and other uplink channels whose resources overlap with the resources occupied by the uplink channel are not sent; If there are multiple uplink channels with the longest symbols, you can continue to determine the transmission scheme based on the starting position. For example, if PUSCH1 and non-associated PUCCH2 have the same starting position, but PUCCH2 occupies the longest symbol, the terminal does not send this PUSCH1 but sends PUCCH2. As shown in Figure 3e, the first uplink shared channel and the first uplink control channel have the same starting position, and the first uplink shared channel overlaps with the first uplink control channel and the second uplink control channel, the terminal may only send the first uplink control channel. An uplink shared channel without sending the first uplink control channel and the second uplink control channel overlapping with it.

In another example, for multiple uplink channels with overlapping resources, the uplink channel with the longest symbol is determined first, and then from the uplink channel with the longest symbol, the position of the starting symbol is determined to be earlier or foremost. Uplink channel, the uplink channel that transmits the start symbol earlier or foremost, and does not send other uplink channels that overlap with the resources occupied by the upstream or foremost uplink channel of the start symbol; The above method is executed for multiple uplink channels with overlapping resources.

In another example, if the symbol lengths of the overlapping multiple uplink channels are the same, the position of the start symbol is sent earlier or the first uplink channel, and the resources occupied by the non-transmission and the position of the start symbol are more recent. Other uplink channels where resources occupied by the previous or foremost uplink channel overlap. That is to say, the embodiments of the present application do not limit the foregoing examples. For example, it may be the transmission with the last start position and/or the shortest symbol, and the rest are not transmitted. For example, you can select an optional channel transmission method in combination with application scenarios.

In yet another optional embodiment, in some application scenarios, the channel transmission method may include: once the resources occupied by multiple uplink channels overlap, the terminal may not send all overlapping uplink channels. For example, as shown in FIG. 3d, the terminal may not send the first uplink control channel, the first uplink shared channel, and the second uplink control channel.

In yet another optional embodiment, the channel transmission method may include: overlapping resources occupied by multiple uplink channels, sending the uplink shared channel first and discarding the uplink control channel; or sending the uplink control channel first and discarding the uplink sharing channel. For example, as shown in Figure 3d, the terminal may only send the first uplink shared channel, without sending the first uplink control channel and the second uplink control channel; or, the terminal may only send the first uplink control channel and the second uplink control channel without sending The first uplink shared channel.

It can be seen that the manner of determining how to transmit overlapping uplink channels in the embodiments described in 4 above is relatively simple, which can greatly reduce the processing burden of the terminal, and at the same time, the uplink channels with the early start symbol or the symbol length can be sent preferentially. .

5. Another channel transmission method when the resources occupied by multiple uplink channels overlap

This application also provides a channel transmission method. In the channel transmission method, the terminal can learn that the resources occupied by the associated uplink channels overlap, and the resources occupied by the non-associated uplink channels also overlap. The terminal can determine the transmission of these uplink channels by itself Program. Wherein, the associated uplink channels can be multiplexed when the aforementioned preconditions are met. Therefore, since the resources occupied by the first uplink shared channel overlap with the resources occupied by the first uplink control channel and the resources occupied by the second uplink control channel, the terminal can have the following multiple choices and have sufficient freedom.

For example, the terminal may send the first uplink control channel and the second uplink control channel separately, and not send the first uplink shared channel.

For another example, if a timing condition is satisfied between the first uplink control channel and the first uplink shared channel, the terminal multiplexes part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel and carries On the first uplink shared channel, then according to an optional rule, at least one of the first uplink shared channel and the second uplink control channel is sent according to the channel transmission method described in point 2 above.

For another example, when determining that the second uplink control channel includes HARQ-ACK, the terminal may separately send the first uplink control channel and the second uplink control channel, but not the first uplink shared channel.

For another example, according to the channel transmission method described in point 4 above, the terminal may select an uplink channel with an early transmission start symbol or a symbol length occupied for priority transmission.

For the network device side, the network device corresponding to the first uplink control channel and the first uplink shared channel does not know the transmission scheme selected by the terminal. Therefore, in an optional implementation manner, the network device may detect the first uplink control channel twice, that is, detect the first uplink control channel on the resources of the first uplink control channel respectively, and perform the detection on the first uplink shared channel. The first uplink shared channel is detected on the resource, so that the network device obtains uplink control information. Wherein, the uplink control information comes from the first uplink control channel or from the first uplink shared channel. Specifically, if the first uplink control channel is successfully detected on the resources of the first uplink control channel, the uplink control information comes from the first uplink channel. If the first uplink control channel fails to be detected on the resources of the first uplink control channel, the uplink control information is detected on the resources of the first uplink shared channel, and the uplink control information is the uplink control information carried by the first uplink control channel and The uplink control information after the uplink control information carried by the first uplink shared channel is multiplexed.

That is, the network device receives the first uplink control channel on the resources of the first uplink control channel, and receives the first uplink shared channel on the first uplink shared channel. If the network device does not receive the first uplink control channel, it acquires part or all of the information carried by the first uplink control channel from the received first uplink shared channel, and Information carried by an uplink shared channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network equipment associated with the first uplink control channel and the first uplink shared channel needs to be detected one more time. If the network device corresponding to the second uplink control channel detects information, the decoding is successful; if no information is detected, the decoding fails.

Please refer to FIG. 7. FIG. 7 is a schematic diagram of a device provided by an embodiment of the application.
