Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a channel transmission method and a related device.
Background
In a Fifth Generation (5G) communication system, a Multi-transmission and reception point (Multi-TRP) transmission technology is a key technology for improving the overall performance of the system and solving the inter-cell interference problem. The Multi-TRP transmission technology comprises a plurality of schemes such as a joint transmission technology, a dynamic transmission point selection technology, cooperative scheduling and the like in an implementation mode.
Currently, in the Multi-TRP transmission technology, a plurality of network devices are allowed to send different downlink Control information to the same terminal device, so that the terminal device can send a corresponding Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) to the corresponding network device according to each downlink Control information. Since real-time information interaction cannot be performed among a plurality of TRPs, it is expected that UCI information carried on a PUCCH or a PUSCH may be transmitted to a corresponding network device in real time. However, when a terminal device transmits PUCCH and PUSCH to different network devices, there is a case where resources of a plurality of PUCCH and PUSCH overlap, and therefore, when a plurality of PUCCH and PUSCH overlap, how to transmit these uplink channels becomes an urgent problem to be solved.
Disclosure of Invention
The application provides a channel transmission method and related equipment, which can transmit at least one uplink channel under the condition that resources occupied by a plurality of uplink channels are overlapped.
In a first aspect, a terminal determines that a resource occupied by a first uplink shared channel overlaps with a resource occupied by a second uplink control channel, and the terminal may send at least one of the first uplink shared channel and the second uplink control channel. Therefore, the channel transmission method can realize the transmission of at least one uplink channel when the resources occupied by a plurality of uplink channels are overlapped in the multi-point cooperative transmission, which is favorable for avoiding the waste of transmission resources caused by the fact that all overlapped uplink channels cannot be transmitted, so that at least one of the network equipment corresponding to the first uplink shared channel and the network equipment corresponding to the second uplink control channel obtains the uplink control information.
In an optional embodiment, the sending, by the terminal, at least one of the first uplink shared channel and the second uplink control channel may include: and the terminal sends the first uplink shared channel and the second uplink control channel. And sending the first uplink shared channel and the second uplink control channel, wherein the resources occupied by the first uplink shared channel are processed by punching. The resources occupied by the second uplink control channel are not overlapped with the resources occupied by a Demodulation Reference Signal (DMRS) corresponding to the first uplink shared channel, the total number of bits of information carried by the second uplink control channel is less than or equal to a first preset threshold, and the terminal transmits the first uplink shared channel and the second uplink control channel by punching on the resources occupied by the first uplink shared channel.
In another optional embodiment, the sending, by the terminal, at least one of the first uplink shared channel and the second uplink control channel may include: and the terminal sends one of the first uplink shared channel and the second uplink control channel. And the terminal sends one of the first uplink shared channel and the second uplink control channel, wherein the resources occupied by the second uplink control channel are overlapped with the resources occupied by the demodulation reference signal corresponding to the first uplink shared channel, or the total bit number of the information carried by the second uplink control channel is greater than the first preset threshold value.
As can be seen, in the two embodiments, when the resource occupied by the second uplink control channel does not overlap with the resource occupied by the DMRS corresponding to the first uplink shared channel, that is, the second uplink control channel does not affect the DMRS corresponding to the first uplink shared channel, and the total bit number of information carried by the second uplink control channel is less than or equal to the first preset threshold, the terminal may both send the two overlapping uplink channels; and the second uplink control channel affects the DMRS corresponding to the first uplink shared 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 transmitted. Therefore, the two embodiments described above are advantageous for the terminal to feed back 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 predetermined threshold may be 2bits or 4bits, etc. The first preset threshold value can be configured according to requirements.
In one case, the terminal may determine whether the first uplink shared channel and the first uplink control channel can both be transmitted in a puncturing manner, considering 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. In another case, the terminal may also consider whether the transmission power of the resource position overlapped between the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel exceeds the maximum transmission power, and if the transmission power exceeds the maximum transmission power, the terminal may not consider multiplexing, and select one channel from the resources for transmission; if the maximum transmit power is not exceeded, the preconditions for the first case described above may be further considered. It can be seen that the precondition of the second case can prevent the uplink shared channel from being unable to be received due to too small transmission power after the resources occupied by the uplink shared channel are punctured.
In an optional implementation manner, the terminal sends one of the first uplink shared channel and the second uplink control channel. In an optional implementation manner, the sending, by the terminal, 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 second uplink control channel; or, the terminal sends the first uplink shared channel and 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, the terminal does not send the first uplink shared channel, and sends the second uplink control channel; and the information carried by the second uplink control channel does not contain HARQ-ACK, and the terminal sends the first uplink shared channel and does not send the second uplink control channel. It can be seen that, in this embodiment, on one hand, it is beneficial for the terminal to preferentially send the HARQ-ACK to the network device, and on the other hand, it is beneficial for the terminal to preferentially send UCI information and/or data carried by the uplink shared channel to the network device.
In a second aspect, the present application further provides a channel transmission method, where resources occupied by a first uplink shared channel overlap with resources occupied by a second uplink control channel, the resources occupied by the first uplink shared channel overlap 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 transmission schemes of the first uplink shared channel and the first uplink control channel. For example, the timing condition is not satisfied between a first uplink shared channel and the first uplink control channel, the terminal does not transmit the first uplink shared channel, and transmits the first uplink control channel and the second uplink control channel; the terminal multiplexes part or all of information carried by the first uplink control channel and information carried by the first uplink shared channel and carries the information on the first uplink shared channel when the time sequence condition is satisfied between the first uplink shared channel and the first uplink control channel, and executes the step of transmitting at least one of the first uplink shared channel and the second uplink control channel.
As can be seen, in this embodiment, when determining to transmit a first uplink shared channel in response to overlapping of resources occupied by a first uplink shared channel and resources occupied by a first uplink control channel, at least one of the first uplink shared channel and the second uplink control channel is transmitted in response to overlapping of resources occupied by the first uplink shared channel and resources occupied by the second uplink control channel; in addition, in this embodiment, part or all of the information in the first uplink control channel bearer information may be multiplexed with the information carried in the first uplink shared channel, so as to send UCI information carried in the overlapped uplink channel to each network device as much as possible.
In the channel transmission method, the terminal may multiplex part or all of information carried by the first uplink control channel and information carried by the first uplink shared channel, and any one of the following embodiments may be included. For example, the terminal multiplexes HARQ-ACK included in the first uplink control channel bearer information and information carried by the first uplink shared channel by puncturing the resources of the first uplink shared channel, where the number of bits of HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the terminal multiplexes the HARQ-ACK included in the first uplink control bearer information and the information carried by the first uplink shared channel in a rate matching manner, where a bit number of the HARQ-ACK included in the first uplink control bearer information is greater than the second preset threshold;
or the terminal multiplexes the channel state information contained in the first uplink control channel bearer information with the information borne by the first uplink shared channel in a rate matching manner, wherein the information borne by the first uplink shared channel does not contain the channel state information;
or the terminal multiplexes the channel state information, except for the periodic channel state information, included in the first uplink control channel bearer information with the information carried by the first uplink shared channel in a rate matching manner, where the information carried by the first uplink shared channel includes the channel state information.
The second preset threshold may be a preset number of bits for HARQ-ACK. The second predetermined threshold may be 2 bits. The second preset threshold value can be configured according to requirements.
In an optional implementation manner, in a first aspect, the terminal sends one of the first uplink shared channel and the second uplink control channel, and in the channel transmission method in the second aspect, the method may include the following steps: the terminal does not send the first uplink shared channel and sends the second uplink control channel, wherein the priority of the first uplink shared channel bearing information is lower than or equal to the priority of the second uplink control channel bearing information; or, the terminal sends the first uplink shared channel and does not send the second uplink control channel, wherein the priority of the first uplink shared channel carrying information is higher than or equal to the priority of the second uplink control channel carrying information. Since in this aspect, the HARQ-ACK included in the first uplink control channel bearer information may be carried by the first uplink shared channel, this embodiment is favorable for sending the information with the highest priority to the network device based on the comparison of priorities.
For example, the priority of the information carried by the first uplink shared channel is determined by the information with the highest priority in the information carried by the first uplink shared channel; the priority of the information carried by the second uplink control channel is determined by the information with the highest priority in 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 hybrid automatic repeat request acknowledgement information HARQ-ACK and channel state information; the information carried by the second uplink control channel comprises at least one uplink control information in 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, the embodiment is advantageous for transmitting the uplink control information with high priority to the network device based on the comparison of the priorities.
The channel state information carried by the first uplink control channel may include periodic channel state information (P-CSI), semi-static channel state information (semi-CSI), and the like. 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). Wherein, semi-static channel state information (semi-CSI) is configured on which channel of the uplink control channel and the uplink shared channel to transmit, and 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 that of the channel state information, so that the HARQ-ACK can be fed back to the network device as fast as possible. In another alternative embodiment, 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 soon as possible. Therefore, the priority of the two is not limited in the embodiments of the present application, and the priority may be predefined or configured in combination with the application scenario.
In an optional implementation manner, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the first uplink shared channel, and the semi-CSI carried on the first uplink control channel may be: "priority of AP-CSI" is higher than "priority of semi-CSI carried on uplink shared channel"; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on an uplink control channel" is higher than the "priority of P-CSI". Therefore, in the first aspect and the second aspect, 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 channel may not be multiplexed, that is, the P-CSI is discarded, so that the occupied proportion of the multiplexing mode to the resource of the first uplink shared channel is reduced while the UCI information with higher priority is sent to the network device.
In another optional embodiment, the priority level of each piece of channel state information may also be predefined or configured according to an application scenario. The embodiments of the present application are not limited.
In an optional embodiment, the priority of the first uplink shared channel carrying information is determined by whether the first uplink shared channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK; the priority of the second uplink control channel carrying information is determined by whether the second uplink control channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK. Therefore, the embodiment is beneficial to sending the HARQ-ACK with high priority to the network equipment based on the comparison of the priority, so as to quickly retransmit the wrong data.
In this embodiment of the present application, whether the first uplink control channel and the first uplink shared channel are associated may be determined by whether downlink control related parameters corresponding to the respective channels 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 equipment; correspondingly, the uplink control channel and the uplink shared channel are not associated, which means that the uplink control channel and the uplink shared channel are respectively sent to different network devices.
In a third aspect, the present application further provides a channel transmission method, which is different from the channel transmission methods in the two aspects, in that in the channel transmission method, resources occupied by a first uplink control channel are overlapped with resources occupied by a first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel; correspondingly, the terminal sends one of the first uplink shared channel and the first uplink control channel.
In this aspect, in an alternative implementation manner of "the terminal transmits one of the first uplink shared channel and the first uplink control channel", reference may be made to the related contents of the second aspect. For example, the sending, by the terminal, one of the first uplink shared channel and the first uplink control channel may include: the terminal multiplexes part or all of information in first uplink control channel bearing information and information borne by the first uplink shared channel and bears the information on the first uplink shared channel, and then the terminal can send the first uplink shared channel without sending the first uplink control channel, wherein a time sequence condition is met between the first uplink control channel and the first uplink shared channel; or, the terminal does not send the first uplink shared channel, and sends the first uplink control channel, where a timing condition is not satisfied between the first uplink control channel and the first uplink shared channel. In addition, how to multiplex part or all of the information carried by the first uplink control channel with the information carried by the first uplink shared channel may also refer to the related content of the second aspect, and details are not described here.
In a fourth aspect, the present application further provides a channel transmission method, where in comparison with the channel transmission method in the third aspect, a resource occupied by a first uplink control channel overlaps with a resource occupied by a first uplink shared channel, and the resource occupied by the first uplink shared channel overlaps with a resource occupied by a second uplink control channel; in this way, the terminal transmits one of the first uplink shared channel and the first uplink control channel in response to the overlapping of the resource occupied by the first uplink control channel and the resource occupied by the first uplink shared channel, and further determines the transmission scheme of the first uplink shared channel and the second uplink control channel in response to the overlapping of the resource occupied by the first uplink shared channel and the resource occupied by the second uplink control channel.
For example, the terminal performs puncturing on a resource occupied by the first uplink shared channel and a resource overlapped with a resource occupied by the second uplink control channel, and sends the second uplink control channel, and performs the operation of sending one of the first uplink shared channel and the first uplink control channel according to the third aspect, where the resource occupied by the second uplink control channel and the resource occupied by the demodulation reference signal corresponding to the first uplink shared channel are not overlapped, and the total number of bits of information carried by the second uplink control channel is less than or equal to a second preset threshold; or,
the terminal does not send the first uplink shared channel, and sends the second uplink control channel and the first uplink control channel, wherein the resource occupied by the second uplink control channel is overlapped with the resource occupied by the demodulation reference signal corresponding to the first uplink shared channel, and the information carried by the second uplink control channel comprises HARQ-ACK, or,
the total bit number of the information carried by the second uplink control channel is greater than the preset threshold value, and the information carried by the second uplink control channel comprises HARQ-ACK; or,
the terminal does not send the second uplink control channel, and executes the operation of sending one of the first uplink shared channel and the first uplink control channel in the third aspect, wherein the resource occupied by the second uplink control channel is overlapped with the resource 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 total bit number of the information carried by the second uplink 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, the present application further provides a channel transmission method, where implementation conditions of the optional transmission scheme are not agreed between the terminal and the network device, that is, the terminal determines an uplink channel transmission mode when the first uplink shared channel overlaps with both the first uplink control channel and the second uplink control channel, and the network device side does not know how the terminal will transmit the uplink channel.
For example, the terminal may send the first uplink control channel and the second uplink control channel, respectively, without sending the first uplink shared channel; or, the terminal multiplexes part or all of the information carried by the first uplink control channel and the information carried by the first uplink shared channel, and carries the information on the first uplink shared channel, and then sends at least one of the first uplink shared channel and the second uplink control channel according to an optional rule, such as the channel transmission method described in the first aspect above, where 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 perform the above step of transmitting the first uplink control channel and the second uplink control channel, respectively, and not transmitting the first uplink shared channel.
Correspondingly, for the network device side, since the network devices corresponding to the first uplink control channel and the first uplink shared channel do not know the transmission scheme selected by the terminal, the network device may detect information carried by the first uplink control channel twice, that is, detect the first uplink control channel on the resource of the first uplink control channel, and if the detection fails, detect the first uplink shared channel on the resource of the first uplink shared channel, and the detected first uplink shared channel also carries information carried by the multiplexed first uplink control channel. Specifically, for the channel transmission method according to the first to fifth aspects, the operations of the network device side may refer to the following sixth and seventh aspects.
In a sixth aspect, the present application further provides a channel transmission method, which is set forth from the perspective of the network device side.
In the channel transmission methods according to the first to fifth aspects, when the resource occupied by the second uplink control channel overlaps with the resource occupied by the first uplink shared channel, for example, TRP2, in one case, the terminal does not transmit the second uplink control channel, in another case, the terminal transmits the second uplink control channel in a puncturing manner on the resource of the first uplink shared channel, and in yet another case, the terminal transmits the second uplink control channel. Therefore, for TRP2, either normal reception is successful or reception is failed, and therefore TRP2 does not require an addition of another operation mode.
In the channel transmission method according to the first to fifth aspects, the association between the first uplink control channel and the first uplink shared channel may correspond to the same network device, such as TRP1, and when the resource occupied by the first uplink control channel overlaps with the resource occupied by the first uplink shared channel, 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 and the information carried by the first uplink shared channel, carries the information on the first uplink shared channel, and sends the first uplink shared channel; in another case, the terminal does not transmit the first uplink shared channel and transmits the first uplink control channel. Therefore, for TRP1, the first uplink control channel is either received on its resources and the first uplink shared channel is not received; or receiving the first uplink shared channel without receiving the first uplink control channel, wherein the first uplink shared channel carries part or all of the information in the first uplink control channel carrying information. Therefore, the channel transmission method described in the present aspect is explained below from the viewpoint of TRP 1.
In the channel transmission method, network equipment receives a first uplink control channel on the resource of the first uplink control channel; the network equipment receives a first uplink shared channel on the resource of the first uplink shared channel; the network equipment acquires uplink control information; the uplink control information is from the first uplink control channel or from the first uplink shared channel; and the resources occupied by the first uplink control channel are overlapped with the resources occupied by the first uplink shared channel, and the first uplink control channel is associated with the first uplink shared channel. That is, when the uplink control information acquired by the network device is from the first uplink control channel, the uplink control information only includes information carried by the first uplink control channel; if the information is from the first uplink shared channel, the information may be carried in the first uplink shared channel after multiplexing the information carried in the first uplink control channel and the information carried in the first uplink shared channel, for example, the information may include UCI carried in the first uplink control channel and UCI carried in the first uplink shared channel.
In an optional embodiment, the network device receives a first uplink control channel on a resource of the first uplink control channel; the network equipment receives the first uplink shared channel on the resource of the first uplink shared channel when not receiving the first uplink control channel; the network equipment acquires part or all of information in first uplink control channel bearing information from the received first uplink shared channel, and acquires the information borne by the first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network device may detect the information carried by the first uplink control channel twice, that is, on one hand, detect on the resource of the first uplink control channel, and if not, may detect part or all of the information carried by the first uplink control channel on the resource of the first uplink shared channel. Therefore, when the resources occupied by a plurality of uplink channels are overlapped, more uplink control information can be acquired as far as possible.
In another optional implementation manner, the network device receives a first uplink shared channel on a resource of the first uplink shared channel; the network equipment receives the first uplink control channel on the resource of the first uplink control channel when not receiving the first uplink shared channel; the network equipment acquires part or all of information in the first uplink control channel bearing information 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 device may detect the uplink control information, that is, on the one hand, detect on the resource of the first uplink control channel, and if not, may detect part or all of the information carried by the first uplink control channel on the resource of the first uplink shared channel. Therefore, when the resources occupied by a plurality of uplink channels are overlapped, more uplink control information can be acquired as far as possible.
It can be seen that the channels from which the uplink control information obtained by the above two embodiments comes are different, and the obtained uplink control information may also be different.
In an optional implementation manner, HARQ-ACK included in the first uplink control channel bearer information is multiplexed with information carried by the first uplink shared channel in a manner of puncturing resources occupied by the first uplink shared channel, and is carried on the first uplink shared channel, where a bit number of HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner, and is borne on the first uplink shared channel, where a bit number of the HARQ-ACK included in the first uplink control channel bearer information is greater than the second preset threshold. Therefore, the embodiment is beneficial for the network device to acquire the HARQ-ACK included in the first uplink control channel bearer information on the resource corresponding to the puncturing manner or the resource corresponding to the rate matching.
In an optional implementation manner, channel state information CSI included in the first uplink control channel bearer information is multiplexed with information carried by the first uplink shared channel in a rate matching manner, and is carried on the first uplink shared channel, where the information carried by the first uplink shared channel does not include CSI; or, the channel state information, except for the periodic channel state information P-CSI, in the first uplink control channel bearer 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, where the information carried by the first uplink shared channel includes AP-CSI. Therefore, the method and the device are beneficial for the network device to acquire the channel state information contained in the first uplink control channel bearing information or the channel state information contained in the first uplink control channel bearing information except for the P-CSI on the resource corresponding to the rate matching.
In a seventh aspect, the present application further provides a channel transmission method, similar to the sixth aspect, in which, from the network device side, as described in the TRP1, resources occupied by the first uplink control channel overlap resources occupied by the first uplink shared channel, and the first uplink control channel is associated with the first uplink shared channel. The difference between the channel transmission method and the channel transmission method described in the above sixth aspect is that the network device can detect the first uplink control channel once, and does not need to detect information carried by the first uplink control channel twice, which is beneficial to reducing the processing load of the network device, and is explained below.
In the channel transmission method, network equipment determines that a first uplink control channel is associated with a first uplink shared channel, and resources occupied by the first uplink control channel are overlapped with resources occupied by the first uplink shared channel; and the network equipment receives one of the first uplink control channel and the first uplink shared channel.
In an optional implementation manner, the network device determines that a first uplink control channel is associated with the first uplink shared channel, and resources occupied by the first uplink control channel overlap with resources occupied by the first uplink shared channel; and the network equipment receives one of the first uplink control channel and the first uplink shared channel.
For example, the network device receives a first uplink control channel, and does not receive a first uplink shared channel, where a timing condition is not satisfied between the first uplink shared channel and the first uplink control channel; or, the network device receives the first uplink shared channel, does not receive the first uplink shared channel, and obtains, from the first uplink shared channel, part or all of information in the first uplink control channel bearer information and information carried by the first 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, HARQ-ACK included in the first uplink control channel bearer information is multiplexed with information carried by the first uplink shared channel in a manner of puncturing resources occupied by the first uplink shared channel, and is carried on the first uplink shared channel, where when a bit number of HARQ-ACK included in the first uplink control channel bearer information is less than or equal to a second preset threshold; or, the HARQ-ACK included in the first uplink control channel bearer information is multiplexed with the information borne by the first uplink shared channel in a rate matching manner, and is borne on the first uplink shared channel, where a bit number of the HARQ-ACK included in the first uplink control channel bearer information is greater than the second preset threshold.
In an optional implementation manner, channel state information CSI included in the first uplink control channel bearer information is multiplexed with information carried by the first uplink shared channel in a rate matching manner, and is carried on the first uplink shared channel, where the information carried by the first uplink shared channel does not include CSI; or, the channel state information, except for the periodic channel state information P-CSI, in the first uplink control channel bearer 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, where the information carried by the first uplink shared channel includes aperiodic channel state information AP-CSI.
The applicable scene of the embodiment of the application can be an Ultra-Reliable and low-Latency communication (URLLC) scene or an Enhanced mobile broadband (eMBB) scene. In the URLLC scenario, only one uplink shared channel, for example, one PUSCH, is allowed to be transmitted in one time unit. In an eMBB scenario, two uplink control channels and one uplink shared channel may be allowed in the same time unit, and both uplink control channels may carry HARQ-ACK. The time unit may be one slot or one micro slot mini-slot.
In yet another aspect, the channel transmission method may include: once the resources occupied by the multiple uplink channels are overlapped, the terminal may not transmit all the overlapped uplink channels, that is, all the overlapped uplink channels are discarded as long as there is an overlap of the resources occupied by the uplink channels.
In yet another aspect, the channel transmission method may include: the resources occupied by a plurality of uplink channels are overlapped, an uplink shared channel is preferentially sent, and an uplink control channel is discarded; or preferentially sending the uplink control channel and discarding the uplink shared channel.
In another aspect, the present application further provides a channel transmission method, where when resources occupied by a plurality of uplink channels overlap, multiplexing the associated uplink channels by using the method of the third aspect; secondly, for the uplink channels after multiplexing, the associated uplink channels which can not be multiplexed, and the non-associated uplink channels, which uplink channels are transmitted and which uplink channels are not transmitted can be determined according to the initial position and the occupied symbol length of each uplink channel. In particular, reference is made to the following detailed description. Correspondingly, the network device side may perform the correlation operation described in the sixth aspect, and further, may determine the uplink channel sent by the terminal in combination with the starting position and the occupied symbol length of the uplink channel, and receive the uplink channel on the resource of the uplink channel sent.
It can be seen that the manner of determining how to transmit the overlapped uplink channels is relatively simple, which can greatly reduce the processing load of the terminal, and at the same time, can preferentially transmit the uplink channel with the start position of the symbol relatively ahead or the occupied symbol relatively long.
In another aspect, the present application also provides a terminal, where the terminal has some or all of the functions of the terminal in the above method examples, for example, the functions of the terminal may have some or all of the functions in the embodiments of the present application, or may have functions of implementing any of the embodiments of the present application separately.

Detailed Description
This application is intended to present various aspects, embodiments or features around a system that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.
In addition, in the embodiments of the present application, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term using examples is intended to present concepts in a concrete fashion.
In the embodiment of the present application, information (information), signal (signal), message (message), channel (channel) may be mixed, and it should be noted that the intended meanings are consistent when the differences are not emphasized. "of", "corresponding", and "corresponding" may sometimes be used in combination, it being noted that the intended meaning is consistent when no distinction is made.
The technical scheme of the application can be specifically applied to various communication systems, such as: global System for mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division multiple Access (TD-SCDMA), Universal mobile telecommunications System (Universal mobile telecommunications System, UMTS), Long Term Evolution (Long Term Evolution, LTE), etc. with the continuous development of communication technology, the solution of the present application can also be used in future networks, such as the 5G System, New Radio (NR), or in device-to-device (device to device, D3: 3D, 2M, M) systems, etc.
The technical scheme of this application still can be applied to in the car networking, that is to say, the terminal that this application said also can be for the vehicle or be applied to the vehicle subassembly in the vehicle. In which, under the LTE system proposed by the 3rd generation partnership project (3 GPP), a vehicle networking (V2X) technology (X stands for anything) in which a vehicle communicates with anything is proposed. The communication method in the V2X system is collectively referred to as V2X communication. For example, the V2X communication includes: communication between a vehicle and a vehicle (V2V), communication between a vehicle and a roadside infrastructure (V2I), communication between a vehicle and a pedestrian (V2P), or communication between a vehicle and a network (V2N), and the like. Communication between terminal devices involved in the V2X system is widely referred to as Sidelink (SL) communication.
At present, vehicles or vehicle components can obtain road condition information or receive service information in time through V2V, V2I, V2P or V2N communication modes, which can be collectively referred to as V2X communication. Fig. 1 is a schematic diagram of a prior art V2X system. The schematic includes V2V communication, V2P communication, and V2I/N communication. The V2X communication is a basic technology and a key technology applied in a scene with a very high requirement on communication delay in the future, such as intelligent automobiles, automatic driving, intelligent transportation systems, and the like, for high-speed devices represented by vehicles.
As shown in fig. 1, the vehicles or vehicle components communicate with each other via V2V. The vehicle or the vehicle component can broadcast the information of the speed, the driving direction, the specific position, whether the emergency brake is stepped on and the like of the vehicle or the vehicle component to surrounding vehicles, and drivers of the surrounding vehicles can better sense the traffic condition outside the sight distance by acquiring the information, so that the dangerous condition is pre-judged in advance and avoided; the vehicle or vehicle component communicates with a roadside infrastructure, which may provide access to various service information and data networks for the vehicle or vehicle component, via V2I. The functions of non-stop charging, in-car entertainment and the like greatly improve the traffic intelligence. Roadside infrastructure, for example, roadside units (RSUs) include two types: one is a terminal equipment type RSU. Since the RSU is distributed on the roadside, the RSU of the terminal equipment type is in a non-mobile state, and the mobility does not need to be considered; the other is a RSU of network device type. The RSU of this network device type may provide timing synchronization and resource scheduling to the vehicle or vehicle component in communication with the network device. The vehicle or vehicle component communicates with the person via V2P; the vehicle or vehicle component communicates with the network via V2N, and V2N may be referred to collectively as V2I/N with V2I described above.
The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
In this embodiment, a part of the scenarios in the present application is described by taking a scenario of an NR network in a wireless communication network as an example, it should be noted that the scheme in the embodiment of the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.
In this application, a network device may be a device with a wireless transceiving function or a chip disposed on the device, and the network device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), wireless fidelity (WIFI) system, Access Point (AP), wireless relay Node, wireless backhaul Node, transmission point (TRP or transmission point, TP), etc., and may also be 5G, such as NR, a gbb in the system, or a transmission point (TRP or TP), a group or group of antennas of a base station in the 5G system, or a panel of a base station (including multiple antennas, or a panel of a base station, such as a BBU), a network Node (RNC, a Node B) in the system, or a BBU in the system, distributed unit), etc., the aforementioned RSUs of network devices or types of network devices in the V2X internet of vehicles.
In some deployments, the gNB or transmission point may include a Centralized Unit (CU) and a DU. The gNB may also include a Radio Unit (RU). A CU implements part of the function of a gNB or a transmission point, and a DU implements part of the function of the gNB or the transmission point, for example, the CU implements the function of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer, and the DU implements the function of a Radio Link Control (RLC), a Media Access Control (MAC) layer and a Physical (PHY) layer. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PHCP layer signaling, may also be considered to be transmitted by the DU or by the DU + RU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a wireless terminal in the aforementioned V2X car networking, or an RSU of a wireless terminal type, and the like. The embodiments of the present application do not limit the application scenarios.
For the convenience of understanding the embodiment of the present application, the communication system shown in fig. 2 is taken as an example for explanation. Referring to fig. 2, fig. 2 is a schematic diagram of cooperative transmission of multiple transmission receiving points TRP according to an embodiment of the present application, and fig. 2 illustrates that both network devices TRP1 and TRP2 are capable of communicating with a terminal.
With the rapid development of mobile communication, coordinated multipoint transmission technology can improve system performance, especially improve the spectrum efficiency at the cell edge. As shown in fig. 2, the terminal may determine a Physical Uplink Control Channel (PUCCH) 1 and a Physical Uplink Shared Channel (PUSCH) 1 corresponding to the TRP1, and a PUCCH2 corresponding to the TRP 2; furthermore, the terminal needs to transmit a Physical Uplink Control Channel (PUCCH) 1 and a Physical Uplink Shared Channel (PUSCH) 1 to the TRP 1; the PUCCH2 is transmitted to TRP 2. Once the resources occupied by multiple uplink channels overlap, such as the above PUSCH1, PUCCH1 and PUCCH2, how the terminal should transmit the uplink channels is an urgent problem to be solved, so as to facilitate the network device to obtain the uplink control information carried by the uplink channels sent by the terminal.
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 a plurality of uplink channels when resources occupied by the plurality of uplink channels overlap, and is beneficial for a network device to obtain uplink control information carried by the uplink channel sent by a terminal.
To facilitate understanding of the embodiments of the present application, a few related concepts will be briefly described.
In this embodiment, the resource overlapping occupied by the multiple uplink channels may include overlapping on time domain resources, frequency domain resources, or time-frequency domain resources.
The Time domain resource may refer to a subframe, a slot (slot), a radio frame, a micro slot (mini slot or sub slot), multiple aggregated slots, multiple aggregated subframes, a symbol, or the like, or a Transmission Time Interval (TTI). The time domain may include one or more time units, one time unit may include an integer number of another time unit, or a duration of one time unit in the time domain is equal to a duration of an integer number of another time unit in the time domain, for example, a timeslot/subframe/radio frame includes an integer number of symbols, a timeslot/subframe/radio frame includes an integer number of timeslots, a radio frame includes an integer number of subframes, and the like.
The frequency domain resources include subcarriers, Resource Blocks (RBs), physical resource blocks (PRGs), virtual resource blocks (vrbs), precoding resource block groups (PRGs), physical Resource Block Groups (RBGs), subbands (subbands), partial bandwidths (partial bandwidths), bandwidth parts (BWPs), carriers (carriers), serving cells (serving cells), frequency bands (bands), and the like.
The time frequency resources comprise frequency domain resources corresponding to certain time domain resources.
In the embodiment of the present application, the overlapping of the resources occupied by the multiple uplink channels may be that the resources occupied by the multiple uplink channels are partially overlapped or completely overlapped in a section of time domain unit (also referred to as time unit), or a section of frequency domain unit, or a section of time frequency unit. For example, the overlapping of the resources occupied by the multiple uplink channels may be, on one timeslot or one symbol, the overlapping of the resources occupied by the multiple uplink channels; or, on one subcarrier or resource block, the resources occupied by a plurality of uplink channels are overlapped. Correspondingly, the present application takes the resource overlapping occupied by at least two uplink channels of the first uplink control channel, the second uplink control channel, and the first uplink shared channel as an example to describe the channel transmission method of the terminal or the network device, and the "first" and "second" in the present application do not refer to numbers or sequences.
In this embodiment of the present application, resources occupied by multiple uplink channels overlap, which may also be referred to as resource overlapping occupied by multiple uplink channels, or multiple uplink channel collision, or transmission collision of multiple uplink channels, and the like, and this embodiment of the present application is not limited thereto.
In this embodiment, the uplink channel may be a generic name of an uplink control channel and an uplink shared channel, that is, the uplink channel may be an uplink control channel or an uplink shared channel unless otherwise specified. The Uplink Control Channel may include a Physical Uplink Control Channel (PUCCH) and an Enhanced Physical Uplink Control Channel (EPUCCH); the Uplink shared Channel may include a Physical Uplink Shared Channel (PUSCH).
The "associated uplink channel" described in the embodiment of the present application may be a resource occupied by an associated uplink control channel and a resource occupied by an uplink shared channel; the non-associated uplink channel may be a resource occupied by a non-associated uplink control channel and a resource occupied by an uplink shared channel. 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 equipment; correspondingly, the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel are not associated, which 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 resource occupied by the uplink control channel is related to the resource occupied by the uplink shared channel may be determined by whether the downlink control related parameters respectively corresponding to the channels are the same.
In an optional implementation manner, if the uplink control Channel includes hybrid automatic Repeat request (HARQ) -acknowledgement information (ACK), the downlink control related parameter corresponding to the uplink control Channel is a downlink control related parameter of a data Channel corresponding to scheduling the HARQ-ACK, such as DCI of a Physical Downlink Shared Channel (PDSCH); the downlink control parameter corresponding to the uplink shared channel is a downlink control related parameter of the DCI for scheduling the uplink shared channel, so that whether the resource occupied by the uplink control channel is related to the resource occupied by the uplink shared channel can be determined according to whether the two downlink control related parameters are the same. For example, HARQ-ACK carried by the PUCCH is fed back for data carried by the PDSCH, and the downlink control related parameter corresponding to the PUCCH is a downlink control related parameter of DCI1 scheduling the PDSCH; accordingly, the downlink control related parameter corresponding to the PUSCH is the downlink control related parameter of the DCI2 scheduling the PUSCH, and therefore, when the downlink control related parameter of the DCI1 is the same as the downlink control related parameter of the DCI2, 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 parameter corresponding to the uplink control channel is a downlink control related parameter carried in configuration information of channel state information carried by the uplink control channel; thus, 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, the PUCCH does not include HARQ-ACK but includes channel state information, and the downlink control related parameter corresponding to the PUCCH is a downlink control related parameter carried in the configuration information of the channel state information; correspondingly, when the downlink control related parameters carried in the configuration information of the channel state information are the same as the downlink control related parameters in the DCI2 scheduling the PUSCH, the PUCCH is associated with the PUSCH.
The downlink Control related parameter may include a physical downlink Control Channel configuration parameter (PDCCH-configuration), a Control Resource set configuration parameter (CORESET group), or a Control Resource set configuration parameter group (CORESET group), and the like. The PDCCH-Config includes parameters for detecting a candidate downlink Control Channel (PDCCH). The CORESET can be called as a control resource set, namely, time-frequency resources of the CORESET, such as the size of a resource block occupied by a frequency domain, the number of symbols occupied by a time domain and the like; the CORESET refers to related parameters of signaling configuration and is used for obtaining CORESET time-frequency resources. The CORESET group may include one or more control resource set configuration parameters or index numbers of the control resource set configuration parameters, wherein one control resource set configuration parameter may be represented by one index number or one identifier. When a CORESET group contains a CORESET, the identification of the CORESET group can be used as the identification of the CORESET, or the identification of the CORESET can be used as the identification of the CORESET group. Other downlink control channel configuration parameters are similar.
In the embodiment of the present application, the harq acknowledgement information is used for performing positive (ACK) or Negative (NACK) feedback on received data, such as data carried by the PDSCH, so that the lost or erroneous data can be quickly retransmitted. In the embodiment of the present application, the HARQ-ACK described is not a single-finger positive feedback, but all feedbacks of data carried by the corresponding PDSCH are referred to. For convenience of description herein, the hybrid automatic repeat request acknowledgement information is simply described as HARQ-ACK.
In the embodiment of the present application, for association between an uplink control channel and an uplink shared channel, if information carried on the uplink control channel needs to be multiplexed with information carried on the uplink shared channel and is carried on the uplink shared channel, a certain time delay needs to be satisfied between the uplink shared channel and the uplink control channel, or a time sequence condition needs to be satisfied between the uplink control channel and the uplink shared channel. The timing condition may also be referred to as a delay relationship or a multiplexing timing condition, that is, the terminal needs to have the capability of reporting the downlink shared channel prepared by itself. That is, data information, CSI information, multiplexed information, and the like carried by the downlink shared channel need to be considered. For example, when the uplink shared channel is transmitted, processing time delay of the downlink shared channel and a Demodulation Reference Signal (DMRS) corresponding to the downlink shared channel needs to be considered according to the capability of the terminal; when the aperiodic CSI exists, the processing time delay of the CSI also needs to be considered; and processing time delay of the uplink shared channel and the corresponding DMRS need to be considered according to the capability of the terminal. Therefore, if part or all of the information carried by the uplink control channel and the information carried by the uplink shared channel are multiplexed and carried on the uplink shared channel for transmission, the uplink shared channel needs to satisfy the above processing delay.
In the embodiment of the present application, "multiplexing" has two cases, where the first multiplexing refers to that, for the uplink control channel is associated with the uplink shared channel and the resource occupied by the uplink control channel overlaps with the resource occupied by the uplink shared channel, information carried by the uplink control channel is multiplexed with information carried by the uplink shared channel and is carried on the uplink shared channel for transmission; the second multiplexing refers to that, for the uplink control channel and the uplink shared channel being not associated and the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel overlapping, a hole is punched at a resource position overlapping with the resource occupied by the uplink control channel on the resource occupied by the uplink shared channel, so as to simultaneously transmit the uplink control channel and the uplink shared channel.
Part or all information carried by the uplink control channel is multiplexed with the information carried by the uplink shared channel in a puncturing mode, and when the network equipment receives the uplink shared channel, data which are punctured and are not transmitted can be obtained in an error correction mode. Likewise, for puncturing in the second case, the network device may also obtain data that is not transmitted because the resource is punctured by means of error correction.
The "puncturing" in the above two cases multiplexing means that, at the terminal side, a part of resources occupied by the uplink shared channel is removed, and data that should be placed in the part of resources is also skipped or not transmitted, but from the network equipment side, it is also considered that the resources occupied by the uplink shared channel are not missing, so that the skipped or not transmitted data can be obtained by means of error correction.
The difference between the "puncturing" in the above two cases is that in the first case, the punctured position is not necessarily the resource position where the resources occupied by the two uplink channels overlap, and in the second case, the punctured position is necessarily the resource position where the resources occupied by the two uplink channels overlap. In addition, the rate matching in the first case multiplexing means that, for the terminal side, a part of resources occupied by the uplink shared channel is removed, and meanwhile, data that should be placed in the part of resources is also skipped or not transmitted, and for the network device side, it is also known that the part of resources occupied by the uplink shared channel is missing.
In an optional implementation manner, as a precondition of the "multiplexing" in the second case, whether the resource occupied by the uplink control channel overlaps with the resource occupied by the DMRS corresponding to the uplink shared channel, and a total number of bits of the uplink control channel carrying information are included. In the multiplexing in this case, the resource overlapping with the resource occupied by the uplink control channel is punctured in the resource occupied by the uplink shared channel, which may result in the absence of the DMRS or the inability of the network side to receive the DMRS, affecting channel estimation, and further resulting in the inability to successfully receive the entire uplink shared channel. Therefore, when the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel are not overlapped and the total number of bits of the uplink control channel carrying information is smaller than the first preset threshold, it is necessary to transmit the uplink shared channel and the uplink control channel in the "multiplexing" manner.
In another optional implementation, as to the precondition of "multiplexing" in the second case, it may be considered whether the transmission power of the resource overlapped between the resource occupied by the uplink control channel and the resource occupied by the uplink shared channel exceeds the maximum transmission power, and if the transmission power exceeds the maximum transmission power, the "multiplexing" is not considered any more, and one channel is selected from the resources for transmission; if the maximum transmission power is not exceeded, the precondition in the above embodiment, that is, whether the resource occupied by the uplink control channel and the resource occupied by the DMRS corresponding to the uplink shared channel overlap or not, may be further considered. Therefore, the problem that the uplink shared channel cannot be received due to over-small transmitting power after being punched is avoided.
In this embodiment of the present application, Information carried by an uplink control channel may be referred to as Uplink Control Information (UCI), and the UCI carried by the uplink control channel may include one or more of HARQ-ACK and channel state Information. 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), and the like. The information carried by the uplink shared channel may include one or more of UCI and data information. Wherein, the UCI carried on the uplink shared channel may include semi-static channel state information (semi-CSI), aperiodic channel state information (AP-CSI). Wherein, semi-static channel state information (semi-CSI) is configured on which channel of the uplink control channel and the uplink shared channel to transmit, and UCI information carried by which channel may include the semi-CSI. The information carried by the uplink control channel and the information carried by the associated uplink shared channel are multiplexed, and when the information is carried on the uplink shared channel for transmission, the UCI carried by the uplink shared channel may further 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, wherein the UCI may include channel state information, and when 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, the UCI carried by the uplink shared channel may further include HARQ-ACK.
In an optional implementation manner, the priority of the HARQ-ACK is higher than that of the channel state information, so that the HARQ-ACK can be fed back to the network device as fast as possible. In another alternative embodiment, 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 soon as possible. Therefore, the priority of the two is not limited in the embodiments of the present application, and the priority may be predefined or configured in combination with the application scenario.
In an optional implementation manner, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the uplink shared channel, and the semi-CSI carried on the uplink control channel may be: "priority of AP-CSI" is higher than "priority of semi-CSI carried on uplink shared channel"; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on an uplink control channel" is higher than the "priority of P-CSI". In another optional embodiment, the priority level of each piece of channel state information may also be predefined or configured according to an application scenario. The embodiments of the present application are not limited.
In the embodiment of the application, the priority of the information carried by the uplink shared channel is determined by the priority with the highest priority in the information carried by the uplink shared channel; the priority of the information carried by the uplink control channel is determined by the priority with the highest priority in the information carried by the uplink control channel. For example, the priority of HARQ-ACK is higher than the priority of channel state information, the priority of the uplink shared channel bearer information is determined by whether the uplink shared channel bears hybrid automatic repeat request acknowledgement information HARQ-ACK, and if the uplink shared channel bears HARQ-ACK, the priority of the uplink shared channel bearer information is the highest; if no HARQ-ACK is carried, the priority of the information carried by the uplink shared channel is relatively low; the priority of the information carried by the uplink control channel is determined by whether the uplink control channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK, and if the uplink control channel carries the HARQ-ACK, the priority of the information carried by the uplink control channel is the highest; if no HARQ-ACK is carried, the priority of the information carried by the uplink control channel is relatively low.
Based on the above related explanation, the channel transmission method of the present application can transmit at least one uplink channel when resources occupied by a plurality of uplink channels overlap in a multi-point transmission scenario, so that corresponding network devices can obtain information carried by the transmitted uplink channel in time. In addition, in each embodiment, in a time unit, there are two uplink control channels that may carry HARQ-ACKs, a second uplink control channel, and an uplink shared channel, where the uplink control channel is associated with the uplink shared channel, the second uplink control channel is not associated with other two channels, and resources occupied by the uplink control channel and resources occupied by the uplink shared channel are required to be sent to the TRP1, and the second uplink control channel is required to be sent to the TRP2, which is taken as an example, and the channel transmission method is described with reference to the communication system shown in fig. 2.
As shown in fig. 3a, when the terminal device determines that the resources occupied by the first uplink control channel, the second uplink control channel, and the first uplink shared channel do not overlap with each other in one time unit, the terminal device transmits the three uplink channels, and accordingly, the TRP1 can receive the first uplink control channel and the first uplink shared channel, and the TRP2 can receive the second uplink control channel.
As shown in fig. 3b, the resource occupied by the first uplink control channel overlaps with the resource occupied by the first uplink shared channel, and the resource occupied by the second uplink control channel does not overlap with the resources occupied by the other two uplink channels; as shown in fig. 3c, the resource occupied by the first uplink shared channel overlaps with the resource occupied by the second uplink control channel, and the resource occupied by the first uplink control channel does not overlap with the resources occupied by the other two uplink channels; as shown in fig. 3d, the resource occupied by the first uplink shared channel overlaps with the resource occupied by the first uplink control channel and the resource occupied by the second uplink control channel; as shown in fig. 3e, the resource occupied by the first uplink shared channel overlaps with both the resource occupied by the first uplink control channel and the resource occupied by the second uplink control channel. The channel transmission method is described below in a manner that the terminal interacts with the TRP1 and TRP2 for the overlaps shown in fig. 3b to 3 e. When resources occupied by a plurality of uplink channels overlap, an uplink channel that is not transmitted by the terminal may be referred to as an uplink channel that is discarded by the terminal (that is, the uplink channel is dropped).
1. Channel transmission method when resource occupied by associated uplink control channel and resource occupied by uplink shared channel are overlapped
In this embodiment, when the resource occupied by the associated uplink control channel overlaps with the resource occupied by the uplink shared channel, the terminal transmits one of the uplink shared channel and the uplink control channel.
In an optional implementation manner, the terminal multiplexes information carried by the uplink control channel and 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 without sending the uplink control channel. The embodiment can be executed when the time sequence condition is satisfied between the uplink control channel and the uplink shared channel. Specifically, how to determine whether the timing condition is satisfied can be determined by combining the related concept description section, and is not described in detail herein.
In another optional implementation manner, the terminal does not send the uplink shared channel, and sends the uplink control channel. The embodiment may be performed when the timing condition is not satisfied between the uplink control channel and the uplink shared channel.
The terminal multiplexes the information carried by the uplink control channel and the information carried by the uplink shared channel, and the multiplexing may be performed in a puncturing or rate matching manner.
In one example, the terminal multiplexes HARQ-ACK included in the uplink control channel bearer information and information carried by the uplink shared channel by puncturing the uplink shared channel resources; wherein, the number of bits of HARQ-ACK included in the uplink control channel bearer information is less than or equal to a second preset threshold, and the multiplexing method described in this example may be implemented. In another example, the terminal multiplexes HARQ-ACK included in the uplink control bearer information and information carried by the uplink shared channel in a rate matching manner; the multiplexing method in this example may be performed when the number of bits of HARQ-ACK included in the uplink control bearer information is greater than the second preset threshold.
In yet another example, the terminal multiplexes the channel state information included in the uplink control channel bearer information and the information carried by the uplink shared channel in a rate matching manner; the example method may be performed in such a way that the information carried by the uplink shared channel does not include channel state information.
In another example, when the uplink control channel includes channel state information and the uplink shared channel also includes channel state information, the terminal may discard CSI information included in the uplink control channel, that is, in this case, the terminal does not multiplex the channel state information carried by the uplink control channel. In yet another example, the terminal multiplexes channel state information, other than periodic channel state information P-CSI, included in the uplink control channel bearer information with information carried by the uplink shared channel in a rate-matched manner; the information carried by the uplink shared channel includes channel state information, and the exemplary method may be implemented.
The first preset threshold may be a preset number of bits for HARQ-ACK. The first predetermined threshold may be 2bits or 4bits, etc. The first preset threshold value 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, the HARQ-ACK and P-CSI may be multiplexed with the information carried by the uplink shared channel and sent on the uplink shared channel. For another example, when the uplink control information includes HARQ-ACK and P-CSI, and the uplink shared channel includes AP-CSI, the terminal may discard the P-CSI, multiplex the HARQ-ACK and the information carried by the uplink shared channel, and send the information on the uplink shared channel.
For the network device side, the associated uplink control channel and the uplink shared channel may be sent to the same network device. In an optional embodiment, the network device receives an uplink control channel on a resource of the uplink control channel; the network equipment receives the uplink shared channel on the resource of the uplink shared channel when not receiving the uplink control channel; the network equipment acquires part or all of information in uplink control channel bearing information from the received uplink shared channel, and acquires the information borne by the uplink shared channel; the uplink control channel is associated with the uplink shared channel. It can be seen that the network device may detect the information carried by the uplink control channel twice, that is, detect on the resource of the uplink control channel, and if not, may detect part or all of the information carried by the uplink control channel on the resource of the uplink shared channel. Therefore, the embodiment is beneficial to acquiring more uplink control information by directly detecting when resources occupied by a plurality of uplink channels are overlapped. Accordingly, the network device can determine from how to detect some or all of the information carried by the uplink control channel on the uplink shared channel, as can be seen in the relevant contents multiplexed herein.
In another optional implementation manner, the network device may acquire a condition that resources occupied by an uplink control channel overlap with resources occupied by an uplink shared channel, and determine that the uplink control channel is associated with the uplink shared channel, where the resources occupied by the uplink control channel overlap with the resources occupied by the uplink shared channel; the network equipment receives one of the uplink control channel and the uplink shared channel. For example, when the uplink shared channel and the uplink control channel satisfy a timing condition, the network device receives the uplink shared channel and does not receive the uplink control channel. For another example, when the time sequence condition is not satisfied between the uplink shared channel and the uplink control channel, the network device does not receive the uplink shared channel and receives the uplink control channel. Therefore, in this embodiment, the network device can detect the uplink control channel once, and does not need to detect information carried by the uplink control channel twice, which is beneficial to reducing the processing load of the network device. Accordingly, the network device can determine from how to detect some or all of the information carried by the uplink control channel on the uplink shared channel, as can be seen in the relevant contents multiplexed herein.
As shown in fig. 3b, the resource occupied by the first uplink control channel overlaps with the resource occupied by the first uplink shared channel, and the resource occupied by the second uplink control channel does not overlap with the resource occupied by other uplink channels, so the terminal can transmit the second uplink control channel, and TRP2 can receive the second uplink control channel. Referring to fig. 4, for a first uplink control channel and a first uplink shared channel, the channel transmission method may include the following steps:
101. the terminal determines that the resources occupied by the first uplink control channel are overlapped with the resources 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 and the resources occupied by the first uplink shared channel overlap, or whether the first uplink shared channel and the first uplink control channel are associated, which can be determined by referring to the relevant contents of "overlap" or "association" herein, and will not be described in detail here.
102. The terminal judges whether a time sequence condition is met between the first uplink control channel and the first uplink shared channel, if the time sequence condition is met, step 103 is executed; if the timing condition is not satisfied, go to step 104;
103. the terminal multiplexes part or all of the information carried by the uplink control channel and the information carried by the uplink shared channel in a punching or rate matching mode, carries the information on the first uplink shared channel, and sends the first uplink shared channel without sending the first uplink control channel; the TRP1 may receive the first uplink shared channel, and acquire, from the first uplink shared channel, part or all of information carried by the first uplink control channel and information carried by the first uplink shared channel.
104. The terminal sends a first uplink control channel and does not send a first uplink shared channel; the TRP1 receives the first uplink control channel and does not receive the first uplink shared channel.
Therefore, the channel transmission method can multiplex part or all information carried by the first uplink control channel, namely UCI information, onto the first uplink shared channel in a multiplexing mode to be sent when the first uplink control channel and the first uplink shared channel meet the time sequence condition, so that the TRP1 can obtain the UCI information in time; even if the timing conditions are not met, the first uplink control channel can be sent preferentially, so that the TRP1 can be facilitated to obtain UCI information carried by the first uplink control channel in time.
2. Channel transmission method when resources occupied by non-associated uplink control channel and resources occupied by uplink shared channel are overlapped
In this embodiment, the resource occupied by the uplink control channel overlaps with the resource occupied by the uplink shared channel, 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 is satisfied and the total number of bits of the uplink control channel carrying information is less than or equal to the first preset threshold, a hole may be punched in a resource occupied by the uplink shared channel, a resource overlapped with the resource occupied by the uplink control channel, on the resource occupied by the uplink shared channel, and the uplink control channel and the uplink shared channel may be sent; and when the precondition of the second condition of multiplexing is not met or the total bit number of the uplink control channel bearing information is greater than a first preset threshold, the terminal sends one of the uplink shared channel and the uplink control channel. Accordingly, since the resources occupied by the non-associated uplink control channel and the resources occupied by the uplink shared channel are transmitted to different network devices, each network device can only receive its own uplink control channel and uplink shared channel, and if not, it indicates that the reception is failed.
The first preset threshold may be a preset total number of bits of the uplink control channel bearer information. The first predetermined threshold may be 2bits or 4bits, etc.
In an optional implementation manner, the terminal transmits one of the uplink shared channel and the uplink control channel. In an optional embodiment, the terminal does not send the uplink shared channel, and sends the uplink control channel; or, the terminal sends the uplink shared channel and does not send the uplink control channel. Wherein, the information carried by the uplink control channel comprises hybrid automatic repeat request acknowledgement information HARQ-ACK, the terminal does not send the uplink shared channel, and sends the uplink control channel; the information carried by the uplink control channel does not contain HARQ-ACK, and the terminal sends the uplink shared channel and does not send the uplink control channel. It can be seen that, in this embodiment, on one hand, it is beneficial for the terminal to preferentially send the HARQ-ACK to the network device, and on the other hand, it is beneficial for the terminal to preferentially send UCI information and/or data carried by the uplink shared channel to the network device.
For example, as shown in fig. 3c, the resource occupied by the first uplink shared channel overlaps with the resource occupied by the second uplink control channel, and the resource occupied by the first uplink control channel does not overlap with the resource occupied by other uplink channels, so the terminal can directly transmit the first uplink control channel. Referring to fig. 5, for a first uplink shared channel and a second uplink control channel, the channel transmission method may include the following steps:
201. the terminal determines that the resources occupied by the first uplink shared channel are overlapped with the resources 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 are overlapped or not and whether the total bit number of the uplink control channel bearing information is less than or equal to a first preset threshold or not; if the resources occupied by the uplink control channel and the resources occupied by the DMRS corresponding to the uplink shared channel are not overlapped and the total number of bits of the second uplink control channel bearer information is less than or equal to the first preset threshold, perform step 203; if the resources occupied by the uplink control channel are overlapped with the resources occupied by the DMRS corresponding to the uplink shared channel, or if the total bit number of the information carried by the uplink control channel is greater than the first preset threshold, performing step 204;
203. the terminal transmits the first uplink shared channel and the second uplink control channel in a mode of punching on the resources occupied by the first uplink shared channel; the TRP1 receives a first uplink shared channel, and the TRP2 receives a second uplink control channel;
204. the terminal judges whether the information carried by the second uplink control channel contains HARQ-ACK or not; if yes, go to step 205; if not, go to step 206;
205. the terminal does not send the first uplink shared channel and sends a second uplink control channel; the TRP1 is unable to receive the first uplink shared channel; the TRP2 receives a second uplink control channel;
206. the terminal does not send the second uplink control channel and sends a first uplink shared channel; TRP1 first uplink shared channel, 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 and the resources occupied by the uplink control channel are overlapped, and the second condition "multiplexing" is satisfied and the total number of bits of the uplink control channel carrying information is less than or equal to the first preset threshold, the uplink shared channel and the uplink control channel may be sent respectively; if the second condition is not satisfied, or the total number of bits of the information carried by the uplink control channel is greater than the first preset threshold, if the uplink control channel includes HARQ-ACK, the uplink control channel may be sent without sending the uplink shared channel; therefore, the HARQ-ACK can be sent to the network equipment in time. Correspondingly, if the uplink control channel does not contain the HARQ-ACK, the uplink shared channel may be sent, but the uplink control channel is not sent; therefore, the data and/or the channel state information carried by the uplink shared channel can be transmitted to the network equipment.
3. Channel transmission method when resources occupied by associated uplink channels overlap and resources occupied by non-associated uplink channels also overlap
In the present application, when resources occupied by associated uplink channels overlap and resources occupied by non-associated uplink channels also overlap, the terminal can finally determine which uplink channel to transmit, which uplink channel not to transmit, or all uplink channels, in combination with the above embodiments in the case of overlapping both 1 and 2.
In an optional embodiment, the terminal may determine, for the associated uplink channel, the transmission mode of the associated uplink channel by using the embodiment described in above 1, and then further determine the transmission mode of the non-associated uplink channel by combining with the embodiment described in above 2.
For example, the resource occupied by the first uplink shared channel overlaps with both the resource occupied by the first uplink control channel and the resource occupied by the second uplink control channel, the terminal determines to transmit the first uplink control channel according to the embodiment described in the above 1, and when the first uplink shared channel is not transmitted, the terminal may directly transmit the second uplink control channel without performing the operation in the embodiment described in the above 2; when the terminal determines not to send the first uplink control channel and sends the first uplink shared channel according to the embodiment described in the above 1, the terminal further needs to send at least one of the first uplink shared channel and the second uplink control channel in combination with the steps in the embodiment described in the above 2.
In the channel transmission method according to claim 2, the resources occupied by the second uplink control channel do not overlap with the resources occupied by the Demodulation Reference Signal (DMRS) corresponding to the first uplink shared channel, the total number of bits of the information carried by the second uplink control channel is less than or equal to a first preset threshold, and 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 the resources occupied by the second uplink control channel are overlapped with the resources occupied by the demodulation reference signal corresponding to the first uplink shared channel, or the total bit number of the information carried by the second uplink control channel is greater than the first preset threshold value, and the terminal sends one of the first uplink shared channel and the second uplink control channel.
In this embodiment, the priority of the first uplink shared channel bearer information is lower than or equal to the priority of the second uplink control channel bearer information, and the terminal does not send the first uplink shared channel and sends the second uplink control channel; or, the priority of the first uplink shared channel carrying information is greater than the priority of the second uplink control channel carrying information, and the terminal sends the first uplink shared channel without sending the second uplink control channel.
For example, the priority of the information carried by the first uplink shared channel is determined by the information with the highest priority in the information carried by the first uplink shared channel; the priority of the information carried by the second uplink control channel is determined by the information with the highest priority in 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 hybrid automatic repeat request acknowledgement information HARQ-ACK and channel state information; the information carried by the second uplink control channel comprises at least one uplink control information in 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, the embodiment is advantageous for transmitting the uplink control information with high priority to the network device based on the comparison of the priorities.
For another example, the priority among the AP-CSI, the P-CSI, the semi-CSI carried on the first uplink shared channel, and the semi-CSI carried on the first uplink control channel may be: "priority of AP-CSI" is higher than "priority of semi-CSI carried on uplink shared channel"; "priority of semi-CSI carried on uplink shared channel" is higher than "priority of semi-CSI carried on uplink control channel"; the "priority of semi-CSI carried on an uplink control channel" is higher than the "priority of P-CSI". Therefore, when the information carried by the first uplink control channel and the information carried by the first uplink shared channel are multiplexed, the P-CSI in the first uplink control channel can be not multiplexed, that is, the P-CSI is discarded, so that the occupation proportion of the multiplexing mode to the resource of the first uplink shared channel is reduced while the UCI with higher priority is sent to the network device.
In an optional embodiment, the priority of the first uplink shared channel carrying information is determined by whether the first uplink shared channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK; the priority of the second uplink control channel carrying information is determined by whether the second uplink control channel carries hybrid automatic repeat request acknowledgement information HARQ-ACK. Therefore, the embodiment is beneficial to sending the HARQ-ACK with high priority to the network equipment based on the comparison of the priority, so as to quickly retransmit the wrong data.
For example, as shown in fig. 3d, the resource occupied by the first uplink shared channel overlaps with the resource occupied by the second uplink control channel, and the resource occupied by the first uplink control channel overlaps with the resource occupied by the first uplink shared channel, please refer to fig. 6, the channel transmission method may include the following steps:
301. the terminal determines the resources occupied by the first uplink shared channel, the resources occupied by the first uplink shared channel are overlapped with the resources occupied by the second uplink control channel and the resources occupied by the first uplink control channel, and the first uplink shared channel is associated with the first uplink control channel;
302. the terminal determines 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, executes steps 303 to 304; if the timing condition is not satisfied, go to step 308;
303. the terminal multiplexes part or all of the information carried by the first uplink control channel and the information carried by the first uplink shared channel in a punching or rate matching mode, and carries the information on the first uplink shared channel;
304. the terminal judges whether the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel are overlapped or not, and whether the total bit number of the information carried by the second uplink control channel is less than or equal to a first preset threshold or not; if the resources occupied by the second uplink control channel and the resources occupied by the DMRS corresponding to the first uplink shared channel are not overlapped, and the total number of bits of the second uplink control channel carrying information is less than or equal to a first preset threshold, execute step 307; if the resources occupied by the second uplink control channel are overlapped with the resources occupied by the DMRS corresponding to the first uplink shared channel, or if the total number of bits of the information carried by the second uplink control channel is greater than the first preset threshold, performing step 305;
305. the terminal judges whether the priority of the first uplink shared channel bearing information is lower than or equal to the priority of the second uplink control channel bearing information; if the priority of the first uplink shared channel carrying information is lower than or equal to the priority of the second uplink control channel carrying information, executing 308; if the priority of the first uplink shared channel bearing information is higher than the priority of the second uplink control channel bearing information, executing 306;
306. the terminal sends a first uplink shared channel without sending a first uplink control channel and a second uplink control channel;
307. the terminal transmits the first uplink shared channel and the second uplink control channel in a mode of punching on resources occupied by the first uplink shared channel, and does not transmit the first uplink control channel;
308. and the terminal sends the first uplink control channel and the second uplink control channel without sending the first uplink shared channel.
In another optional embodiment, the terminal may first determine how to send the non-associated uplink channel by using the embodiment described in above 2 for the non-associated uplink channel; and further determining the transmission mode of the remaining overlapped uplink channels by combining the embodiment described in the above 1.
For example, as shown in fig. 3d, the uplink shared channel overlaps with both the uplink control channel and the second uplink control channel, the terminal determines to transmit the second uplink control channel according to the embodiment described in fig. 2, and when the uplink shared channel is not transmitted, the terminal may directly transmit the uplink control channel and the second uplink control channel without performing the operation in the embodiment described in fig. 1; when the terminal determines not to send the second uplink control channel and send the uplink shared channel according to the embodiment described in the above 2, the terminal further needs to send one of the uplink shared channel and the uplink control channel in combination with the steps in the embodiment described in the above 1; when the terminal determines to send the second uplink control channel and the uplink shared channel according to the embodiment described in the above 2, the terminal further needs to combine the steps in the embodiment described in the above 1 to send one of the uplink shared channel and the uplink control channel, and the second uplink control channel.
4. Channel transmission method when resource occupied by multiple uplink channels is overlapped
In the channel transmission method, when resources occupied by a plurality of uplink channels overlap, the uplink channels meeting the "multiplexing" precondition in the first case can be multiplexed for the overlapped associated uplink channels; secondly, for the uplink channels after multiplexing, the associated uplink channels which can not be multiplexed, and the non-associated uplink channels, which uplink channels are transmitted and which uplink channels are not transmitted can be determined according to the initial position and the occupied symbol length of each uplink channel. Alternatively, the uplink channels satisfying the precondition of "multiplexing" in the second case may be multiplexed for the overlapped non-associated uplink channels; secondly, for the multiplexed uplink channels, the non-associated uplink channels that cannot be multiplexed, and the associated uplink channels, which uplink channels to transmit and which uplink channels not to transmit can be determined according to the starting position and the occupied symbol length of each uplink channel. Alternatively, when resources occupied by a plurality of uplink channels overlap, the transmission schemes of the plurality of uplink channels can be determined simply based on the starting position and occupied symbol length of each uplink channel.
For example, for a plurality of uplink channels occupying resources for overlapping, determining an uplink channel with the position of the initial symbol being earlier or foremost, then determining an uplink channel occupying the longest symbol from the uplink channels with the position of the initial symbol being earlier or foremost, transmitting the uplink channel occupying the longest symbol, and not transmitting other uplink channels overlapping with the resources occupied by the uplink channel occupying the longest symbol; and then, the method is executed aiming at the residual uplink channels with a plurality of overlapped occupied resources.
For another example, if the associated PUCCH1 and PUSCH1 are multiplexed as described above and the multiplexed PUSCH1 and non-associated PUCCH2 are also overlapped, the uplink channel with the earlier or foremost start symbol position can be identified from the multiplexed PUSCH1 and non-associated PUCCH2, and if the uplink channel is the multiplexed PUSCH1, the terminal transmits the multiplexed PUSCH1 and will not transmit the PUCCH2 overlapped with the multiplexed PUSCH 1. For another example, as shown in fig. 3d, the uplink channel at the position of the transmission start symbol before or at the forefront is the first uplink control channel, so the terminal may only transmit the first uplink control channel and not transmit the first uplink shared channel and the second uplink control channel.
For another example, if the starting positions of the multiple overlapped uplink channels are the same, the uplink channel occupying the longest symbol can be determined, and the other uplink channel occupying the resource overlapped with the resource occupied by the uplink channel is not transmitted; if there are multiple uplink channels occupying the longest symbols, the transmission scheme can be determined continuously according to the front and back of the starting position. For example, when the PUSCH1 has the same starting position as that of the non-associated PUCCH2 but the symbol occupied by the PUCCH2 is the longest, the terminal does not transmit the PUSCH1 and transmits the PUCCH 2. As shown in fig. 3e, the starting positions of the first uplink shared channel and the first uplink control channel are the same, and the first uplink shared channel overlaps with both the first uplink control channel and the second uplink control channel, the terminal may only transmit the first uplink shared channel, and does not transmit the first uplink control channel and the second uplink control channel overlapping with the first uplink shared channel.
In another example, for a plurality of uplink channels occupying resources in an overlapping manner, an uplink channel occupying the longest symbol is determined, then an uplink channel with a position of a start symbol earlier or foremost is determined from the uplink channel occupying the longest symbol, the uplink channel with the position of the start symbol earlier or foremost is sent, and other uplink channels overlapping with the resources occupied by the uplink channel with the position of the start symbol earlier or foremost are not sent; and then, the method is executed aiming at the residual uplink channels with a plurality of overlapped occupied resources.
In another example, if the occupied symbol lengths of the plurality of overlapped uplink channels are the same, the uplink channel with the position of the start symbol earlier or the most previous uplink channel is transmitted, and the other uplink channel with the occupied resource overlapped with the resource occupied by the uplink channel with the position of the start symbol earlier or the most previous uplink channel is not transmitted. That is, the present embodiment does not limit the above example, and for example, the transmission with the last start position and/or the shortest occupied symbol may be performed, and the rest may not be performed. For example, an alternative channel transmission method may be selected in connection with the application scenario.
In 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 transmit all of the overlapping uplink channels. For example, as shown in fig. 3d, the terminal may not transmit the first uplink control channel, the first uplink shared channel, and the second uplink control channel.
In yet another alternative embodiment, the channel transmission method may include: the resources occupied by a plurality of uplink channels are overlapped, an uplink shared channel is preferentially sent, and an uplink control channel is discarded; or preferentially sending the uplink control channel and discarding the uplink shared channel. For example, as shown in fig. 3d, the terminal may send only the first uplink shared channel, and does not send the first uplink control channel and the second uplink control channel; or, the terminal only sends the first uplink control channel and the second uplink control channel, but does not send the first uplink shared channel.
It can be seen that, in the embodiments described in the above 4, the manner of determining how to transmit the overlapped uplink channels is relatively simple, which can greatly reduce the processing load of the terminal, and at the same time, can preferentially transmit the uplink channel with the early start symbol or the uplink channel with the long occupied symbol.
5. Method for transmitting another channel when resources occupied by a plurality of uplink channels overlap
The present application also provides a channel transmission method, in which a terminal can know that resources occupied by associated uplink channels overlap, resources occupied by non-associated uplink channels also overlap, and the terminal can determine the transmission schemes of the uplink channels by itself. The associated uplink channels may be multiplexed when the above-mentioned precondition is satisfied. Therefore, the terminal may have the following multiple options for overlapping the resource occupied by the first uplink shared channel, the resource occupied by the first uplink control channel, and the resource occupied by the second uplink control channel, and has a sufficient degree of freedom.
For example, the terminal may transmit the first uplink control channel and the second uplink control channel, respectively, without transmitting the first uplink shared channel.
For another example, when the time sequence 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 and the information carried by the first uplink shared channel, and carries the information on the first uplink shared channel, and then sends at least one of the first uplink shared channel and the second uplink control channel according to an optional rule, such as the channel transmission method described in point 2 above.
For example, when it is determined that the second uplink control channel includes HARQ-ACK, the terminal may transmit the first uplink control channel and the second uplink control channel, respectively, without transmitting the first uplink shared channel.
For another example, the terminal may select the uplink channel with the early transmission start symbol or the occupied symbol length to transmit preferentially according to the channel transmission method described in the above point 4.
For the network device side, the network devices corresponding to the first uplink control channel and the first uplink shared channel do 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 for the first uplink control channel, that is, detect the first uplink control channel on the resource of the first uplink control channel and detect the first uplink shared channel on the resource of the first uplink shared channel, so that the network device obtains the uplink control information. Wherein the uplink control information is 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 resource of the first uplink control channel, the uplink control information is from the first uplink channel. And if the uplink detection of the first uplink control channel on the resource of the first uplink control channel fails, detecting uplink control information on the resource of the first uplink shared channel, wherein the uplink control information is the uplink control information which is carried by the first uplink control channel and is multiplexed with the uplink control information carried by the first uplink shared channel.
That is, the network device receives a first uplink control channel on its resources and receives a first uplink shared channel on a first uplink shared channel. If the network device does not receive the first uplink control channel, acquiring part or all of information in the first uplink control channel bearing information and the information borne by the first uplink shared channel from the received first uplink shared channel; the first uplink control channel is associated with the first uplink shared channel. It can be seen that the network device associated with the first uplink control channel and the first uplink shared channel needs to detect more than once. If the information is detected aiming at the network equipment corresponding to the second uplink control channel, the decoding is successful; if no information is detected, decoding failure is indicated.
