Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

In order to improve the link performance, the New Radio (NR) communication system of the fifth generation (5 th generation,5 g) introduces a multiple transmission point (TRP) transmission technology. The multi-TRP transmission technology means that a plurality of TRPs can provide services to the same terminal.

In NR, in order to ensure reliability of data transmission, a hybrid automatic repeat request (HARQ) technique is used. When the initial transmission data of one Transport Block (TB) is not successfully received, the terminal may send a Negative Acknowledgement (NACK) instruction to the TRP, and the TRP retransmits the TB to the terminal according to the NACK instruction.

Accordingly, in order to improve the performance of the uplink edge user, for Uplink Control Information (UCI) transmitted on a Physical Uplink Control Channel (PUCCH), for example, HARQ messages, channel State Information (CSI), uplink Scheduling Request (SR) information, and the like, the transmission performance of the uplink control information may also be improved by a multi-TRP retransmission scheme.

Considering that uplink resources are tense, when retransmitting uplink control information through multiple TRPs, there may be a problem of resource aliasing of resources for retransmitting uplink control information differently, for example, multiple repeated HARQ information is fed back in one timeslot, that is, one timeslot is divided into multiple sub-timeslots, repeated HARQ information is fed back in each sub-timeslot, and meanwhile, SR information needs to be reported in the timeslot. Resource aliasing may exist between the uplink transmission resource for transmitting the HARQ information and the uplink transmission resource for reporting the SR information, which may cause a decrease in the transmission performance of the repeated HARQ information or SR information that is transmitted.

Disclosure of Invention

The embodiment of the application provides a communication method and a communication device, which are used for improving the performance of retransmission data in a communication system.

In a first aspect, the present application provides a communication method, which may be implemented by: determining a first channel resource and at least one second channel resource, the first channel resource being used for transmitting first information; the second channel resource is used for transmitting second information; the first information is transmitted in at least one of the first channel resources, and the second information is transmitted in at least one of the at least one second channel resource; transmitting third information on K third resources when there is resource aliasing in the at least one first resource and the at least one second resource; there is no resource aliasing among the K third resources; and K is a positive integer.

By the method, after the first channel resource and the second channel resource are determined, the first channel resource can be determined to be used for transmitting the first information; the second channel resource is used for transmitting second information; wherein the first information may be transmitted in at least one first resource among the first channel resources and the second information may be transmitted in at least one second resource among the at least one second channel resources.

In a possible implementation manner, when the first information is transmitted on the plurality of first resources, the first information may be repeatedly transmitted information, that is, each first information may be transmitted once on one first resource, and when the second information is transmitted on the plurality of second resources, the second information may be repeatedly transmitted information, that is, each second information may be transmitted once on one second resource. Determining K third resources upon determining that there is resource aliasing in the at least one first resource and the at least one second resource; under the condition that the K third resources do not have resource aliasing, the K third information can still be transmitted, and the third information can be the first information and/or the second information, that is, the repeated transmission of the first information and/or the repeated transmission of the second information can be realized through the K third resources, so that the performance of retransmitting data in the communication system is improved.

That is, the first information may be repeatedly transmitted in at least one of the first channel resources; the second information may be repeatedly transmitted in at least one of the second channel resources; the third information may be repeatedly transmitted in at least one of the K third resources. Therefore, the performance of repeatedly transmitting the third information in the communication system can be effectively improved by the method.

In one possible implementation, the K third resources may achieve a gain of spatial diversity through a multi-TRP architecture. For example, the first TRP is used to transmit at least one third information through at least one of the K third resources. The second TRP is used to transmit at least one third information through at least one of the K third resources. The performance of transmitting repeated data is improved by the first TRP and the second TRP and the gain of space diversity of a multi-TRP framework.

A possible implementation, the resource aliasing is an aliasing of at least one of the following resources: time domain resources, frequency domain resources, or spatial domain resources.

By the method, when a plurality of possible resource aliasing occurs, the resource aliasing can be processed, and the flexibility of the scheme is improved.

In a possible implementation manner, the K third resources are K of N1 first resources in the first channel resources and/or M1 second resources in the second channel resources; the N1 and the M1 are positive integers.

Through the method, K third resources can be determined through the first resource in the first channel resource and the second resource in the second channel resource, and especially, when the first channel resource and the second channel resource include non-aliased resources, the K non-aliased third resources can be determined by considering the aliased resources and the non-aliased resources between the first resource and the second resource at the same time. One possible implementation manner is to perform unified processing by considering the aliasing-existing resource and the non-aliasing-existing resource between the first resource and the second resource at the same time, so that the determined K third resources meet the transmission requirements of the first information and the second information, and meet the transmission performance of the first information and the second information while processing the aliasing-existing resource.

In one possible implementation manner, the third information is at least one of: the first information, derivation information of the first information, or derivation information of the first information and the second information;

the second information, derivation information of the second information, or derivation information of the first information and the second information.

Considering that the first resource and the second resource may adopt different coding manners or different formats, when the determined third resource is the second resource and the third resource transmits the content of the first information, the content of the first information may be transmitted through the second resource, and at this time, the derivation of the first information may be achieved based on transmitting the derivation information of the first information on the second resource, for example, the derivation information of the first information may be obtained according to the coding manner, the format, and the like of the second resource, so that the derivation information of the first information may be transmitted on the second resource. Of course, the corresponding third information may also be determined based on other scenarios, for example, by jointly encoding the first information and the second information (i.e., by deriving information from the first information and the second information), so as to implement the transmission on the corresponding third resource.

In one possible implementation, the K third resources are determined according to at least one of the following:

a value of the first information, a value of the second information, the at least one first resource, the at least one second resource.

For example, when the value of the first information is positive, a manner of selecting the K third resources may be determined, and thus, the K third resources at that time may be determined. At this time, the second information may be sent on the K third resources, that is, the first information may be carried. When the value of the first information is negative, a manner of selecting the K third resources may be determined, thereby determining the K third resources. At this time, the first information may be sent on the K third resources, that is, the first information may carry the second information.

The manner of determining the third resource and the third information is exemplified below by specific examples.

Example one, the first channel resource includes D first resources, and the second channel resource includes E second resources; the K third resources are K first resources, and K is less than or equal to D; or the K third resources are K second resources, and K is smaller than or equal to E.

In this example, it is considered that there is no resource aliasing for K first resources among the first channel resources, and thus, the K first resources among the first channel resources may be transmitted as K third resources. Or, there is no resource aliasing through the K second resources in the second channel resources, so that the K second resources in the second channel resources may be used as the K third resources to transmit the third information.

In another possible scenario, all the first resources in the first channel resources may be used as K third resources, and the third information may be sent to all the first resources in the first channel resources without sending the third information using the second channel resources, so that performance of transmitting the third information is ensured more simply. In the same way, all the second resources in the second channel resources may also be used as K third resources, so that the third information is sent to all the second resources in the second channel resources, instead of sending the third information using the first channel resources.

Second example, when the number of the first information to be sent is smaller than the number of the second information to be sent, and correspondingly, the number of the first resources is smaller than the number of the second resources, which may result in that the first resource in the first channel resources is not enough to meet the requirements of K third resources to send the first information and the second information, a fourth resource may be determined, where the fourth resource may be a resource different from the first resource, for example, R third resources in the K third resources are determined as the fourth resource determined according to the first channel resource;

when the number of the second information to be sent is smaller than the number of the first information to be sent, correspondingly, the number of the second resources is smaller than the number of the first resources, and when a second resource in the second channel resources may be insufficient to meet requirements of K third resources to send the first information and the second information, a fourth resource may be determined, where the fourth resource may be a resource different from the second resource, for example, S third resources in the K third resources are fourth resources determined according to the second channel resources, and S is less than or equal to N; and R is less than or equal to N, and R and S are non-negative integers.

For another example, the fourth resource may be determined for the first channel resource and the second channel resource at the same time, so that the performance of transmitting the first information and the second information by the K third resources is improved. By the method, the problem that the transmission performance of the first information and the second information cannot be met by the resources due to resource aliasing can be solved.

It should be noted that the fourth resource may be predefined by the base station, or semi-statically configured, or dynamically configured; and is not limited thereto. For example, the fourth resource may be configured by the base station when it is determined that aliasing exists in the first resource and the second resource in the first channel resource and the second channel resource after the base station configures the first channel resource and the second channel resource, or may be configured in advance for the aliasing possibly occurring, which is not limited herein.

Example three, consider that in determining the third resources from the first resources and the second resources, the K third resources that may be selected are the first resources or the second resources on the same TRP, or the first resources or the second resources concentrated on several TRPs. The gain of spatial diversity of the multi-TRP architecture cannot be reasonably exploited. Therefore, the quasi co-site relationship of the ith third resource of the K third resources is determined according to at least one of the following: at least one first resource, at least one second resource, a quasi-co-site relationship of a jth third resource of the K third resources, a quasi-co-site relationship of at least one first resource, or a quasi-co-site relationship of at least one second resource; and the i and the j are positive integers less than or equal to K.

Or, when determining the ith third resource of the K third resources, the determination may be further performed according to the quasi co-site relationship of the at least one first resource, the at least one second resource, the jth first resource, or the quasi co-site relationship of the at least one second resource. Wherein i, j is a positive integer less than or equal to K. For example, when it is determined that the 1 st first resource and the 2 nd second resource are 2 possible three resources and both the 1 st first resource and the 2 nd second resource are transmitted on the first TRP, it may be implemented that the second TRP transmits corresponding third information on the 1 st first resource according to the quasi co-site relation of the 1 st first resource. The determined K third resources can be better sent through multiple TRPs respectively, so that the gain of the space diversity of the multiple TRPs can be effectively utilized, and the overall effect of transmitting the third data is improved.

In the fourth example, information on a resource with a small repetition number may be discarded according to the repetition number, and information on a resource with a large repetition number may be sent, so as to preferentially ensure the transmission performance of information with a high repetition number.

In one possible implementation manner, when it is determined that the number of repetitions of the first information transmitted through the first channel resource is greater than the number of repetitions of the second information transmitted through the second channel resource, K third resources are determined through K first resources in the first channel resource.

In some embodiments, when the third information is the second information, the corresponding second information is transmitted on at least one second resource on the second channel resource without resource aliasing with the at least one first resource on the first channel resource.

In some embodiments, upon determining that the number of repetitions of first information transmitted over the first channel resource is less than the number of repetitions of second information transmitted over the second channel resource, canceling transmission of corresponding first information on at least the first resource where resource aliasing exists; determining K third resources by K first resources of the first channel resources without resource aliasing with at least one second resource on the second channel resources; the K third resources are used for transmitting first information corresponding to the K first resources.

In some embodiments, upon determining that a number of repetitions of first information transmitted over the first channel resources is less than a number of repetitions of second information transmitted over the second channel resources, transmitting corresponding second information over at least one of the second channel resources.

In view of the gain of spatial diversity of the multi-TRP architecture, in one possible implementation, the first channel resource is associated with 1 or 2 quasi co-site relationships, and the second channel resource is associated with 1 or 2 quasi co-site relationships.

The quasi-co-location relationship may be a TCI or a spatial relationship (spatial relationship).

In another possible implementation manner, at least one first resource of the first channel resources is transmitted at a first sending and receiving point, at least one first resource of the first channel resources is transmitted at a second sending and receiving point, at least one second resource of the second channel resources is transmitted at the first sending and receiving point, and at least one second resource of the second channel resources is transmitted at a second sending and receiving point; at least one of the K third resources is transmitted at the first transmitting and receiving point, and at least one of the K third resources is transmitted at the second transmitting and receiving point.

By the method, the gain of the space diversity under the multi-TRP architecture can be effectively utilized, and the transmission performance of the third information is improved.

In a possible example, the communication method may be applied to a terminal device, and in this case, the terminal device may further send N first information to the first sending and receiving point on N third resources of the K third resources, and send M first information to the second sending and receiving point on M third resources of the K third resources. Correspondingly, the first sending and receiving point receives the N first information from the terminal on the N third resources. And the second sending and receiving point receives the M first information from the terminal on the M third resources.

In a second aspect, a communication apparatus is provided, which may be a terminal device, a sending and receiving point, a network device, or an apparatus (e.g., a chip, or a system of chips, or a circuit) in the terminal device, the sending and receiving point, or the network device, or an apparatus capable of being used in cooperation with the terminal device, the sending and receiving point, or the network device.

In one design, the apparatus may include a processing module and a communication module. The processing module is used for calling the communication module to execute the receiving and/or sending functions. Further, the communication module may further include a receiving module and a transmitting module.

The processing module is configured to determine a first channel resource and at least one second channel resource, where the first channel resource is used for transmitting first information; the second channel resource is used for transmitting second information; the first information is transmitted in at least one of the first channel resources, and the second information is transmitted in at least one of the at least one second channel resource; transmitting, by the communication module, third information on K third resources when there is resource aliasing in the at least one first resource and the at least one second resource; no resource aliasing exists among the K third resources; and K is a positive integer.

In the embodiment of the present application, when the network device 110 communicates with the terminal device, the number of the network devices may be one or more, and may belong to the same cell or belong to different cells.

The terminal device 120 may be a device with wireless transceiving function, which may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); it may also be deployed in the air (e.g., aircraft, balloons, satellites, etc.), as a device that provides voice or data connectivity to users, or as an internet of things device. And may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, where the terminal equipment may be User Equipment (UE), and the UE includes a handheld device, a vehicle-mounted device, a wearable device, or a computing device having a wireless communication function. The terminal device related to the embodiment of the present application may also be referred to as a terminal, and for example, the UE may be a mobile phone (mobile phone), a tablet computer, or a computer with a wireless transceiving function. The terminal device may also be a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and so on.

In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices. In the technical solution provided in the embodiment of the present application, a device for implementing a function of a terminal is a terminal, and the terminal is a UE as an example, the technical solution provided in the embodiment of the present application is described.

The network device 110 and the terminal device 120 may transmit via radio waves, or may transmit via transmission media such as visible light, laser, infrared, optical fiber, etc. In the embodiment of the present application, a device that realizes the function of the terminal device 120 is referred to as a terminal as an example.

The present application is directed to protocol frameworks such as 5G NR, 5G-Advanced, and the like, which may be applied to various mobile communication scenarios, and fig. 1b is a scenario diagram of a communication system applied in the present invention, such as a scenario of point-to-point transmission between a base station and a UE (user equipment), a scenario of Transmission and Reception (TRP) between a TRP and a UE or between UEs, a scenario of multi-hop/relay transmission between a base station and a UE, and a scenario of DC (dual connectivity) or multi-connectivity between multiple base stations and a UE. It should be noted that fig. 1b is only exemplary and does not limit the network architecture applicable to the present invention, and the present invention does not limit the transmission of uplink, downlink, access link, backhaul (backhaul) link, sidelink (sidelink), etc.

Quasi co-located (QCL) attribute: also called quasi co-location attribute, the definition of QCL in NR protocol is: if the large-scale characteristic of a channel of a certain symbol transmitted on one antenna port can be derived from a channel of a certain symbol transmitted on another antenna port, the two antenna ports are referred to as quasi co-located, which can describe that the two antenna ports have quasi co-location property, and can also describe that the two antenna ports have quasi co-location relationship.

QCL relationships are used to indicate that multiple resources have one or more identical or similar communication characteristics. The same or similar communication configurations may be employed for multiple resources having QCL relationships. For example, if two signals are transmitted from two different antenna ports and experience the same large scale characteristic, the two antenna ports may be considered to have a QCL relationship, and then the large scale characteristic/channel estimation result of a channel for transmitting a symbol at one port may be inferred from the large scale characteristic of a channel for transmitting a symbol at the other port, which is beneficial for processing by the receiver. The large-scale characteristics include one or more of delay spread (delay spread), doppler spread (Doppler spread), doppler shift, average gain, average delay (average delay), and spatial receive parameter (spatial Rx parameter).

In downlink transmission, when a network device uses a specific beam to transmit data to a terminal device, the terminal device needs to be informed of the information of the transmission beam used by the network device, so that the terminal device can receive the data transmitted by the network device using a reception beam corresponding to the transmission beam. The network device indicates, to the terminal device, information related to a transmission beam used by the network device through a TCI field in Downlink Control Information (DCI). Wherein, the TCI field includes 3 bits, which may specifically represent 8 different values (codepoint). Each value of the TCI field corresponds to an index of a transport configuration number state (TCI-state), which may identify a TCI-state. The TCI-state includes a plurality of parameters by which information on the transmission beam can be determined. The TCI-state is configured by the network device to the terminal device, and may include, for example, a TCI-state identifier and two QCL information (QCL-Info). The TCI-state identifier can be regarded as an index of the TCI-state, indicating one TCI-state, and each QCL-Info includes a cell (cell) field and a Bandwidth part (BWP) identifier field, respectively indicating to which BWP of which cell the TCI-state applies, i.e. different wps of different cells or the same cell can configure different QCL-Info. The QCL-Info further includes a reference Signal (reference Signal) field for indicating which reference Signal resource the TCI-state constitutes quasi co-location with.

In uplink transmission, QCL may be determined by spatial relationship.

It should be noted that in the third generation partnership project (3 gpp) R15 (release 15) protocol, the term "beam" does not generally appear, and beams are generally replaced by other terms. For example, in data transmission and channel measurement, beams are mapped to reference signal resources, and one beam corresponds to one reference signal resource. Therefore, in the embodiment of the present application, the description "TCI-state forms a QCL relationship with which reference signal resource" essentially refers to which beam the TCI-state forms a QCL relationship with. QCL relationships refer to two reference signal resources (or two antenna ports, which are also in one-to-one correspondence with reference signal resources) having some identical spatial parameters. The specific spatial parameters are the same depends on the Type of QCL-Info, which is indicated by a QCL Type (QCL-Type) field. The QCL type field may have four values, typeA, typeB, typeC, typeD. Taking typeD as an example, typeD indicates that two reference signal resources have the same spatial reception parameter information, i.e., two beams have the same reception beam. The TCI-state comprises two QCL-Info of which at most there may be one type of TypeD.

The technical scheme provided by the embodiment of the application can be applied to wireless communication among communication devices. The wireless communication between the communication devices may include: wireless communication between a network device and a terminal, wireless communication between a network device and a network device, and wireless communication between a terminal and a terminal. In the embodiments of the present application, the term "wireless communication" may also be simply referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission", or "transmission".

In a wireless communication system, communication devices are included, and wireless communication between the communication devices may be performed using air interface resources. The communication device may include a network device and a terminal device, and the network device may also be referred to as a base station device. The air interface resources may include at least one of time domain resources, frequency domain resources, code resources, and spatial resources. In the embodiments of the present application, at least one may also be described as one or more, and a plurality may be two, three, four or more, which is not limited in the present application.

In the embodiment of the present application, for a technical feature, the technical features in the technical feature are distinguished by "first", "second", "third", "a", "B", "C", and "D", and the like, and the technical features described in "first", "second", "third", "a", "B", "C", and "D" are not in a sequential order or a size order.

The embodiment of the application is suitable for scenes with single or multiple transmitting and receiving devices and any derivative scenes thereof. The sending and receiving device may be a TRP, or a Remote Radio Unit (RRU), and so on. In a scenario of multiple TRPs, multiple TRPs may be connected to the same baseband unit (BBU) or different BBUs. Here, the plurality of TRPs may belong to the same cell or different cells.

In the following, the technical solutions in the embodiments of the present application are clearly and completely described with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, not all embodiments of the present invention.

In order to make the embodiments of the present application clearer, the following sections and concepts related to the embodiments of the present application are collectively described herein.

As shown in fig. 2, a plurality of TRPs exist under one gNB, and communication between the network device and the terminal may be performed through any of the TRPs.

In some application scenarios, a terminal device may communicate with multiple nodes. For example, in a multiple transmission reception point (Multi-TRP) scenario, a terminal device may communicate with a plurality of TRPs.

In order to better understand the scheme provided in the embodiment of the present application, the following first introduces uplink scheduling under a multi-TRP structure.

The network device sends the configuration information of the PUCCH resource to the terminal, and the configuration information of the PUCCH resource is used for transmitting UCI. The terminal may determine a resource location for receiving the UCI according to the configuration information of the PUCCH resource. UCI is transmitted through a bearer in a PUCCH or a Physical Uplink Shared Channel (PUSCH).

The UCI is used to schedule uplink data transmission. For example, UCI may be used to schedule transmission of PUSCH. The terminal can determine the resource position for sending the uplink data according to the received UCI, so as to send the uplink data to the network equipment, and the network equipment determines the resource position for receiving the uplink data according to the UCI and receives the uplink data from the terminal equipment.

Under a multi-TRP architecture, in one implementation, uplink data may be scheduled in a multi-UCI manner. Specifically, each TRP may individually receive UCI transmitted from a terminal. The terminal may send uplink data to the corresponding TRP according to the UCI configured by the network device for each TRP. As shown in fig. 3, taking two TRPs as an example, the two TRPs are represented by TRP1 and TRP2, respectively. The TRP1 may receive UCI1 from a terminal transmission, UCI1 being used to schedule the terminal to transmit PUSCH1. The TRP2 receives UCI2 sent by the terminal, and the UCI2 is used for scheduling the terminal to send PUSCH2.

Taking the configuration of the PUCCH resource as an example, the PUCCH resource may be configured by RRC. The RRC configuration information includes time-frequency domain resource allocation (period and offset) of slot granularity, and further includes a starting symbol index, duration, a starting physical resource block index, a number of occupied physical resource blocks, etc. within a slot.

Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic increase, massive mobile communication device connection, and various new services and application scenarios which are continuously emerging, the fifth generation (5G) mobile communication system is in operation. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications (mtc).

The URLLC service has a very high delay requirement, and the delay requirement of the URLLC service is within 0.5 milliseconds (ms) without considering reliability. On the premise of reaching 99.999 percent of reliability, the transmission delay is required to be within 1 ms. In a Long Term Evolution (LTE) system, the minimum time scheduling unit is a Transmission Time Interval (TTI) of 1ms time symbol.

In order to meet the delay requirement of URLLC service, the data transmission of the wireless air interface may use a shorter time scheduling unit, for example, the minimum time scheduling unit is a sub-slot (sub-slot) or a slot (slot) with a larger sub-carrier interval. One slot may include a plurality of sub-slots, and one sub-slot includes one or more time domain symbols, where the time domain symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols (symbols). The feedback time delay of the URLLC service is reduced by feeding back a plurality of repeated HARQ messages in one time slot, namely dividing one time slot into a plurality of sub-time slots and feeding back the HARQ messages on each sub-time slot. And a plurality of repeated HARQ messages can be fed back in the time slot, so that the performance of the uplink edge user is improved.

Taking NR communication system as an example, PUCCH defines five formats Format0,1,2,3,4 for transmission, as shown in table 1.

TABLE 1

Format numbering	Length of symbol	Number of bearer bits	Length in frequency domain
				0	1-2	<＝2	1RB
1	4-14	<＝2	1RB
				2	1-2	>2	1-16RB
3	4-14	>2	<=16RB, satisfying the product of power of 2,3,5
				4	4-14	>2	1RB

Different formats of PUCCH may be selected for transmission for different UCI types. For example, the type of UCI may include HARQ information, and may also be hybrid automatic repeat request acknowledgement (HARQ-ACK) information, SR information, link recovery request information, and CSI. This is specifically described below for different UCI.

Wherein, the HARQ-ACK information is a feedback for determining whether a Physical Downlink Shared Channel (PDSCH) is correctly received. And if the HARQ-ACK information is correctly received, feeding back an acknowledgement. If not, HARQ-ACK information feedback is not confirmed (NACK). Wherein, the ACK/NACK information is expressed by 1 bit. Since the PDSCH supports TB () and CBG () transmissions. When the PDSCH adopts TB transmission, 2TB transmission is supported at most, so that the bit size of the HARQ-ACK channel is 1-2bits; when the PDSCH adopts CBG transmission, the bit number of the HARQ-ACK is the number of the CBG.

The HARQ-ACK information is fed back once in the form of HARQ-ACK codebook. Currently, NR supports 3 HARQ-ACK codebooks, type-1 HARQ-ACK codebook (semi-static configuration), type-2 HARQ-ACK codebook (dynamic indication) and Type-3 HARQ-ACK codebook (one shot feedback). HARQ-ACK information can be transmitted through all PUCCH formats 0/1/2/3/4. Generally, a PUCCH carrying HARQ-ACK information may be dynamically determined according to a size of the HARQ-ACK information and a Downlink Control Information (DCI) indication. The resource allocation and indication mode of the HARQ is to select a PUCCH resource set according to the number of bits of the HARQ codebook and indicate specific resources through a PUCCH resource indicator carried in the DCI.

Currently, in PUCCH transmission, at most 2 PUCCH resources are transmitted in one slot, and one of them is Format0 or 2 (short Format). For transmission of HARQ, in the protocol Rel-15, at most one PUCCH resource is available for transmission of HARQ within one slot. In the protocol Rel-16, for the separate HARQ feedback, 2 PUCCH resource transmission HARQ can be supported within one slot, and time division multiplexing is performed.

For the MTRP scenario, in order to improve the performance of the uplink edge user, repeated transmission on different TRPs can be realized by configuring PUCCH resources for different TRPs.

In the protocol Rel-15, for the repeated transmission of HARQ, repeated transmission (Inter-slot retransmission) between different slots can be supported. I.e., the same HARQ information is repeatedly transmitted through different TRPs in different slots. For example, as shown in (a) of fig. 4, the 1 st repeated HARQ information is transmitted through the second TRP (TRP # 2) at slot n, and the 2 nd repeated HARQ information is transmitted through the first TRP (TRP # 1) at slot n + 1. Similarly, other UCI information may also be transmitted, for example, the 1 st repeated SR information is transmitted through the first TRP (TRP # 1) on slot n, and the 2 nd repeated SR information is transmitted through the second TRP (TRP # 2) on slot n + 1.

For example, when the HARQ information is transmitted through

formats

1, 3, and 4, the number of repetitions may be: 2,4,8,16, etc. When HARQ information is transmitted in formats 0 and 2, the number of repetitions is at least 2. The specific number of repetitions may be configured by RRC.

Within a slot, non-repeated transmission based on a slot (slot) and a sub slot (sub slot) in one PUCCH resource may be supported. That is, within one slot, different HARQ information can be transmitted through different TRPs. For example, at slot n, HARQ information 1 is transmitted through TRP2, and HARQ information 2 is transmitted through TRP 1; in slot n +1, HARQ information 1 is transmitted through TRP1, and HARQ information 2 is transmitted through TRP 2.

In the protocol Rel-16, for the separated HARQ feedback, within one slot, 2 PUCCH resource transmission HARQ can be supported, and of course, for non-repeated transmission, reference may be made to the above example, and details are not described herein. For example, as shown in fig. 4 (b), the 1 st repeated HARQ information is transmitted through the second TRP (TRP # 2) at the sub-slot n, and the 2 nd repeated HARQ information is transmitted through the first TRP (TRP # 1) at the sub-slot n + 1. For example, in this scenario, the number of repetitions may satisfy: based on the same PUCCH resource carrying the same UCI, it is repeated 2 times within one slot. Similarly, other UCI information may also send duplicate UCI information. For example, the 1 st repeated SR information is transmitted through the first TRP (TRP # 1) at the sub-slot n, and the 2 nd repeated SR information is transmitted through the second TRP (TRP # 2) at the sub-slot n + 1.

The SR information is used for the terminal to apply for uplink scheduling resources. The LRR information is similar to an SR and is used for the link failure recovery request. The SR associates different logical channels at the MAC-CE layer. In the physical layer, the SR is transmitted in a periodic manner.

Taking NR communication system as an example, configuration of maximum 8 SR information is supported. The SR information is realized in the form of on-off keying, that is, positive (positive) indication is sent to indicate that the terminal requests the uplink scheduling resource, negative (negative) indication is sent to indicate that the terminal does not request the uplink scheduling resource, and the network equipment determines whether the terminal sends the request of the uplink scheduling resource or not according to the received SR information and whether the SR information in the loaded channel is positive or negative. In the protocol, the SR information can be transmitted through PUCCH format 0/1. For example, the PUCCH carrying SR information may be RRC signaling semi-statically configured.

As shown in fig. 4, for the repeated transmission of SR information, it may support repeated transmission (Inter-slot retransmission) between different slots, and also support repeated transmission based on slots (slots) and sub-slots (sub-slots) in one PUCCH resource. For the non-repeated transmission of the SR information, non-repeated transmission (Inter-slot retransmission) between different slots may be supported, and non-repeated transmission based on a slot (slot) and a sub-slot (sub-slot) in one PUCCH resource may also be supported.

The CSI information is used for feeding back channel state information, and comprises quantized information of the characteristic channel state such as RI, PMI, CQI, L1-SINR/L1-RSRP and the like. The CSI is usually large, so PUCCH format 2/3/4 may be used for transmission when reporting CSI periodically or semi-continuously. When reporting CSI aperiodically, PUSCH may be used for transmission. For example, the PUCCH carrying CSI information may be RRC signaling semi-statically configured.

Due to the limitation of uplink resources, there may be resource overlap of PUCCH resources configured by the network device. For example, when at least one time-frequency domain resource overlaps among 1 or more PUCCH resources for transmitting duplicate data, collision or aliasing is considered to occur when UCI is transmitted through the overlapping PUCCH resources.

For another example, when the repeated data is transmitted between different transmission channels, there may be resource overlapping, which may cause interference in the repeated data transmitted between different transmission channels when the corresponding repeated data is transmitted by using the transmission channels, and at this time, it may also be considered that the resources between the different channels are collided or aliased. For example, a resource repeatedly transmitted through the PUCCH and a resource repeatedly transmitted through the PUSCH collide or alias; or, the resource repeatedly transmitted through the PUSCH and the resource repeatedly transmitted through the PUSCH collide or alias; collision or aliasing occurs between a resource that is repeatedly transmitted through a Physical Downlink Control Channel (PDCCH) and a resource that is repeatedly transmitted through the PDCCH; or, collision or aliasing occurs between the resources that are repeatedly transmitted through the PDCCH and the resources that are repeatedly transmitted through the PDSCH; or, collision or aliasing occurs to the resource repeatedly transmitted through the PDSCH and the resource repeatedly transmitted through the PDSCH; or, collision or aliasing occurs to the resource repeatedly transmitted through the PUCCH and the resource repeatedly transmitted through the PDSCH; or, collision or aliasing occurs to the resource repeatedly transmitted through the PUSCH and the resource repeatedly transmitted through the PDDCH; or, the resource repeatedly transmitted through the PUSCH and the resource repeatedly transmitted through the PDSCH collide or alias. In the following embodiments, a scenario where collision occurs when at least one PUCCH resource transmits repeated UCI is taken as an example for description in the present application, and a manner of transmitting repeated data on other channels may refer to this example, and is not described herein again. In addition, the following example does not limit whether the PUCCH resource for transmitting the repeated data is Intra-slot PUCCH retransmission or Inter-slot PUCCH retransmission.

In the following, when 2 repeated UCIs are transmitted on 2 PUCCH resources, the 2 PUCCH resources may be channel resources used for transmitting repeated data, that is, the channel resources include 2 PUCCH resources, and the PUCCH resources have aliasing and collision. Taking 2 repetitions as an example, multiple repetitions can be referred to this example. Hereinafter, the reference numeral of the timing determination repetition resource is explained, for example, the first channel resource includes a1 st first resource (repetition # 11) and a2 nd first resource (repetition # 2), and the timing of the 1 st first resource (repetition # 12) is earlier than that of the 2 nd first resource (repetition # 2). For example, the 2 first resources may be 2 second resources within a time slot. The 1 st first resource may be at least one symbol in one slot, so that the terminal may transmit the 1 st repeatedly transmitted first information on the 1 st first resource, and the 2 nd first resource may be at least one other symbol in the 1 slot except for the 1 st first resource, so that the terminal may transmit the 2 nd repeatedly transmitted first information on the 2 nd first resource.

Similarly, the second channel resource may include a1 st second resource (repetition # 21) and a2 nd second resource (repetition # 22) which are repeatedly transmitted. For example, the 1 st second resource may be at least one symbol in one slot, so that the terminal may transmit the 1 st repeatedly transmitted second information on the 1 st second resource, and the 2 nd second resource may be at least one symbol other than the 1 st second resource in the 1 slot, so that the terminal may transmit the 2 nd repeatedly transmitted second information on the 2 nd second resource.

In the inter-slot scenario, the 2 first resources may be 1 second resource in slot n, and 1 second resource in slot n + 1. The 1 st first resource may be at least one symbol in a slot n such that the terminal may transmit the 1 st repeatedly transmitted first information on the 1 st first resource, and the 2 nd first resource may be at least one symbol in a slot n +1 such that the terminal may transmit the 2 nd repeatedly transmitted first information on the 2 nd first resource. The second resource may refer to the first resource, which is not described herein again.

Denoted as r #11 and r #12 in fig. 5 a. With multiple TRP scenarios, TRP #1 and TRP #2 transmit 1 first UCI of 2 repetitions of the first UCI through 1 first resource of the first channel resources, respectively, and the second channel resources include 1 st second resource (repetition # 1) and 2 nd second resource (repetition # 2), denoted as r #21 and r #22 in fig. 5 a. In connection with the multiple TRP scenario, the TRP #1 and TRP #2 transmit 1 of the 2 repeated second UCI through 1 of the second channel resources, respectively. As shown in fig. 5a, taking the first UCI as HARQ information and the second UCI as SR information as an example, a scenario where aliasing occurs to PUCCH resources may include any one of the following:

1) As shown in fig. 5a (a), there is resource aliasing in the first resource repetition #1 (r # 11) of the first channel resource and the second resource repetition #1 (r # 21) of the second channel resource;

2) As shown in fig. 5a (b), there is resource aliasing in the first resource repetition #1 (r # 11) of the first channel resource and the second resource repetition #2 (r # 22) of the second channel resource;

3) As shown in fig. 5a (c), there is resource aliasing in the first resource repetition #2 (r # 12) of the first channel resource and the second resource repetition #1 (r # 21) of the second channel resource;

4) As shown in fig. 5a (d), there is resource aliasing of the first resource repetition #2 (r # 12) and the second resource repetition #2 (r # 22) of the first channel resource;

5) As shown in fig. 5a (e), there is an aliasing of the first resource repetition #1 (r # 11) of the first channel resource and the second resource repetition #1 (r # 21) of the second channel resource, and there is also a resource aliasing of the first resource repetition #2 (r # 12) of the first channel resource and the second resource repetition #2 (r # 22) of the second channel resource.

The resource aliasing may be aliasing on time domain resources, aliasing on frequency domain resources, or aliasing on space domain resources. The aliasing on the spatial resources may be the aliasing between different beams, or the aliasing of other spatial resources. In the present application, the spatial domain between different TRPs is not regarded as an alias on spatial resources.

As shown in fig. 5b, taking the first channel resource as the first UCI for transmitting repetition, and the second channel resource as the second UCI for transmitting single second UCI or non-repetition second UCI as an example, it is described that there is aliasing collision for resources in the PUCCH resource set. In the example, 2 repetitions are taken as an example, and reference may be made to the example for the multiple repetitions. At this time, the first channel resources include a1 st first resource (repetition # 1) and a2 nd first resource (repetition # 2), which are denoted as r #11 and r #12 in the drawing. In connection with a multi-TRP scenario, the TRP #1 and the TRP #2 respectively transmit repeated first UCI of a terminal through first channel resources, and the second channel resources include a second resource (r # 2) for transmitting second UCI through the TRP #1 or TRP #2. A scenario in which resources in the PUCCH resource set are aliased may include any of:

1) As shown in fig. 5b (a), aliasing exists between repetition #1 (r # 11) of the first channel resource and the second resource (r # 2) of the second channel resource;

2) As shown in (b) of fig. 5b, aliasing exists between repetition #2 (r # 12) of the first channel resource and the second resource (r # 2) of the second channel resource.

A possible collision avoidance mode can determine a resource in two collided resources, one UCI corresponding to the two original collided resources is sent on the resource, the other UCI is discarded, and the non-collided resource still sends the corresponding UCI according to the original mode. By adopting the discarding mode, repeated resources which may cause collision are discarded, and after discarding, the number of received repeated instances is reduced, for example, when multiple repeated instances (for example, SR information) corresponding to multiple repeated PUCCH resources collide, the collided instances are discarded, and the non-collision is not processed and continues to transmit, which may cause performance degradation and even chain scission. For example, for URLLC service, 4 repetitions are needed to achieve the edge user performance, but since the repeated instances are discarded, only 2 repeated instances can be received, the performance requirement cannot be met, and demodulation cannot be performed.

There are at least two ways to determine a resource based on two resources of a collision, which are illustrated by fig. 5c in conjunction with the collision scenario of fig. 5 b.

For example, as shown in (a) of fig. 5c, when the collided resource and the non-collided resource are all transmitted through one TRP, for example, TRP #2 transmits the 1 st repeatedly transmitted first UCI and transmits the 2 nd repeatedly transmitted first UCI. However, TRP #1 does not have any UCI transmission, which results in that spatial diversity gain caused by repeated UCI transmission in a multi-TRP scenario cannot be reasonably utilized, performance is degraded, and even a broken link (such as URLLC service) is generated.

Another possible scenario is as shown in (b) of fig. 5c, in a specific example, 2 repeated first UCI are transmitted on 2 first resources, 1 second UCI is transmitted on 1 second resource, and there is aliasing between the repetition #2 (r # 12) of the first channel resource and the second resource of the second channel resource, and at this time, it is also possible to transmit the second UCI on the repetition #2 of the first channel resource and discard the 2 nd first UCI, that is, transmit the second UCI through TRP # 1. The 1 st first UCI is transmitted through a repetition #1 of the TRP #1 first channel resource. At this time, for the receiving end, the discarded duplicate data of the first UCI causes performance degradation of the first UCI, and the gain of spatial diversity of multiple TRPs disappears.

Another possible collision avoidance method may determine one resource from the two collided resources, and send two UCIs corresponding to the two collided resources on the resource to implement multiplexing of UCI, where the resource that is not collided still sends corresponding UCI according to the original method.

There may be at least two ways to determine a resource based on two resources of a collision, as illustrated by fig. 5c in conjunction with the collision scenario of fig. 5 b.

For example, as shown in (c) of fig. 5c, when the multiplexed resources and the non-multiplexed resources are all transmitted through one TRP, for example, TRP #2 transmits multiplexed 1 st and second UCI and transmits 2 nd first UCI. However, the TRP #1 does not have any UCI transmission, so that the spatial diversity gain caused by repeated UCI transmission in a multi-TRP scene cannot be reasonably utilized, and the performance is reduced.

In addition, this approach may cause HARQ and SR information sent by the terminal to be multiplexed or not multiplexed, and for a receiving end (e.g., a TRP, a terminal device, or a network device), it cannot be distinguished whether multiplexing is performed or not, which may cause the receiving end to fail to correctly receive corresponding UCI, resulting in performance degradation.

Another possible scenario is to transmit 2 repeated first UCI on 2 first resources, 1 second UCI on 1 second resource, and there is aliasing between repetition #2 (r # 12) of the first channel resource and the second resource of the second PUCCH resource set, in this case, it may also be to multiplex repetition #2 of the first channel resource and transmit the 2 nd first UCI and the second UCI of the first UCI through TRP #1, as shown in (d) of fig. 5c, by using a specific example. The 1 st first UCI is transmitted through a repetition #1 of the TRP #1 first channel resource. At this time, for the receiving end, it is determined that SR information is multiplexed on HARQ information on a repetition #2 of the first channel resource, but SR information is not multiplexed on the repetition #1 of the first channel resource, through the 1 st first resource and the 2 nd first resource of the first PUCCH set that cannot be transmitted through the TRP # 1.

In the examples of fig. 5a and 5b, a first resource of the first channel resources may be a PUCCH resource for transmitting HARQ information or CSI information, and a second resource of the second channel resources may be a PUCCH resource for transmitting SR information. Alternatively, the second resource of the second channel resources may be a PUCCH resource for transmitting HARQ information or CSI information, and the first resource of the first channel resources may be a PUCCH resource for transmitting SR information.

In the following, taking a first PUCCH resource for HARQ information and a second PUCCH resource for SR information as an example, the present application provides a communication method, which is used to solve the problem of collision of PUCCH resources on the premise of ensuring transmission performance of a multi-TRP architecture. The following description is given taking an example in which a multi-TRP architecture includes two TRPs, for example, a first TRP and a second TRP. Optionally, 3 or more TRPs may be included, and the specific implementation manner may be implemented based on an existing scheme, or implemented by referring to the first TRP and the second TRP, which is not described herein again.

As shown in fig. 6a and fig. 6b, for a communication method provided by the present application, the method may be performed by a network device, may also be performed by a terminal device, and may also be performed by multiple devices (for example, a first device or a second device), where in a multi-TRP architecture, the first device or the second device may be a first TRP or a second TRP. Under other communication system architectures, the first device or the second device may be a terminal device, a network device, or a relay device, which is not limited herein. In the following, the communication method is described as an example executed under a multi-TRP architecture, and when the first device or the second device is a terminal or a network device of another communication system, the implementation of the example may be referred to, and details are not described herein. The method comprises the following steps:

step 601: a first channel resource and a second channel resource are determined.

In a possible implementation manner, the first channel resource and the second channel resource are channel resources configured in advance by the base station. That is, the terminal device may receive the first indication signaling, and the first indication signaling may be RRC signaling or DCI indication. And obtaining the configuration information of the first channel resource configured by the base station, so that the terminal equipment determines the first channel resource according to the configuration information of the first channel resource configured by the base station. The terminal equipment transmits first information in at least one first resource in the first channel resources. The terminal device may receive the second indication signaling, and the second indication signaling may be RRC signaling or DCI indication. And obtaining the configuration information of the first channel resource configured by the base station, thereby determining the second channel resource according to the configuration information of the second channel resource configured by the base station. The terminal device may then transmit second information on at least one of said second channel resources.

Wherein, step 601 can be performed by the terminal device, the first TRP and the second TRP. The first channel resource is associated with 1 or 2 quasi co-site relations, and the second channel resource is associated with 1 or 2 quasi co-site relations.

For example, the first information is transmitted on the first channel resource through one TRP, or the first information is transmitted on the first channel resource through 2 TRPs. The second information is transmitted on the second channel resource through one TRP, or the second information is transmitted on the second channel resource through 2 TRPs.

Or, at least one first resource of the first channel resources is transmitted at a first transmitting and receiving point, at least one first resource of the first channel resources is transmitted at a second transmitting and receiving point, at least one second resource of the second channel resources is transmitted at the first transmitting and receiving point, and at least one second resource of the second channel resources is transmitted at the second transmitting and receiving point.

For another example, the first channel resource is used for transmitting first information between the terminal device and the network device; the second channel resource is used for transmitting second information between the terminal equipment and the network equipment; the first device or the second device receives or transmits a first message through at least one of the first channel resources, and the first device or the second device receives or transmits a second message through at least one of the second channel resources.

In a possible implementation manner, the first information, the second information, and the third information may satisfy any one of the following: the first information is repeatedly transmitted in at least one of the first channel resources; the second information is repeatedly transmitted in at least one of the second channel resources; the third information is repeatedly transmitted in at least one of the K third resources.

For example, at least one of the first information and the second information is repeatedly transmitted information. For example, the first information may be information that is repeatedly transmitted N1 times on N1 first resources in the first channel resources, and the second information may be information that is repeatedly transmitted M1 times on M1 second resources in the second channel resources.

For example, the first information is taken as the first UCI, and the second information is taken as the second UCI. Of course, the first information and the second information may also be other control information or data transmitted between the terminal device and the network device, and the like, which is not limited herein.

The first UCI may be a UCI repeatedly transmitted N1 times on N1 first PUCCH resources in the first channel resources.

The second UCI may be UCI repeatedly transmitted M1 times through M1 second PUCCH resources in the second channel resources. Under a multi-TRP architecture, for example, a first TRP or a second TRP receives or transmits at least one first UCI through one of the first channel resources, and the first TRP or the second TRP receives or transmits at least one second UCI through one of the second channel resources.

Step 602: and the terminal equipment sends third information on the K third resources when determining that the at least one first resource and the at least one second resource have resource aliasing.

Wherein at least one of the K third resources is transmitted at the first TRP and at least one of the K third resources is transmitted at the second TRP. For example, as shown in fig. 6b, N third resources of the K third resources are transmitted at the first TRP, and M third resources of the K third resources are transmitted at the second TRP.

In one possible implementation manner, the determined K third resources may be determined according to the first channel resources and the second channel resources.

In another possible implementation manner, in step 602, K third resources may be determined according to the configuration information of the first channel resource and the configuration information of the second channel resource. For example, the K third resources are determined according to the first indication signaling and the second indication signaling received by the terminal device.

Considering that the first resource and the second resource may adopt different coding manners or different formats, when the determined third resource is the second resource and the third resource transmits the content of the first information, the content of the first information may be transmitted through the second resource, and at this time, the derivation of the first information may be achieved based on transmitting the derivation information of the first information on the second resource, for example, the derivation information of the first information may be obtained according to the coding manner, the format, and the like of the second resource, so that the derivation information of the first information may be transmitted on the second resource. Of course, the corresponding third information may also be determined based on other scenarios, for example, by jointly encoding the first information and the second information, so as to implement transmission on the corresponding third resource.

For example, K may be equal to N + M, and the N third resources are used for the first TRP to receive or transmit N third information; the M third resources are used for the second TRP to receive or send M third information; n and M are positive integers, and N or M is more than 1.

Accordingly, the first TRP may determine N third resources from the first channel resource and the second channel resource when it is determined that there is resource aliasing in at least one first resource and at least one second resource.

The second TRP may determine, when it is determined that there is resource aliasing of the at least one first resource and the at least one second resource, M third resources according to the first channel resource and the second channel resource.

The following description will take the first information as the first UCI and the second information as the second UCI as an example. That is, there is no resource aliasing between the N + M third resources, and the N third resources are used for the first TRP to receive or transmit N first UCI; the M third resources are used for the second TRP to receive or transmit M first UCIs; the N + M first UCIs are generated according to the first UCI correspondingly transmitted by the first channel resource.

Optionally, the terminal device sends N pieces of third information to the first TRP through the N pieces of third resources. And the terminal equipment sends the M pieces of third information to the second TRP through the M pieces of third resources.

Correspondingly, the first TRP receives N third information from the terminal via the N third resources, and sends N third information to the network device via the N third resources.

When the third information includes the first information, the first TRP receives N first information from the terminal device through the N third resources, and the second TRP receives M first information from the terminal device through the M third resources. When the third information includes the second information, the first TRP receives N second information from the terminal device through the N third resources, and the second TRP receives M second information from the terminal device through the M third resources.

In consideration of the multi-TRP scenario, to achieve the advantage of spatial diversity, at least one first resource and at least one second resource may be included on each TRP. Furthermore, in order to solve the collision problem of the PUCCH resources, the advantage of spatial diversity of multiple TRPs may still be retained, that is, in N + M third resources determined according to the first channel resource and the second channel resource, the N third resources correspond to one TRP, and the M third resources correspond to one TRP. After the problem of resource aliasing is solved, the advantage of space diversity of multiple TRPs can still be ensured.

In some embodiments, the first UCI and the second UCI may be any one of: HARQ information, CSI information, SR information, LLR information. In the following, the first UCI is used as HARQ information, and the second UCI is used as SR information for example, and other information may refer to this example.

There may be multiple implementation manners for determining the N + M third resources, and specific scenarios, for example, the first example to the fourth example, are described below.

Example 1

For the case of the number of the first resource in the first channel resource and the second resource in the second channel resource, the following is divided into scenario 1.1 and scenario 1.2 for example.

Scenario 1.1, the number of first resources in the first channel resources and the number of second resources in the second channel resources are equal. At this time, the number of first UCI transmitted on a first resource among the first channel resources is equal to the number of second UCI transmitted on a second resource among the second channel resources.

Considering that the number of the first resources and the number of the second resources are equal, the N + M third resources are third resources for transmitting the N + M HARQ information, and therefore, the number of the N + M may be the same as the number of the first resources, that is, the number of the second resources. Thus, N + M first resources or second resources may be selected among the first channel resources and the second channel resources as N + M third resources. That is, the N + M third resources are N1 first resources in the first channel resources and N + M second resources in M1 second channel resources; the N1 and the M1 are positive integers.

There are various ways to determine the N + M third resources, which are exemplified by ways A1 to A4 below.

In the method A1, N + M first resources in the first channel resources are used as N + M third resources.

At this time, N1 is equal to N + M.

In the method A2, the N + M second resources in the second channel resources are used as the N + M third resources.

At this time, M1 is equal to N + M.

In the method A3, N first resources in the first channel resources are used as N third resources, and M second resources in the second channel resources are used as M third resources. Wherein the N + M third resources do not overlap.

In the method A4, N second resources in the second channel resources are used as N third resources, and M first resources in the first channel resources are used as M third resources. Wherein the N + M third resources do not overlap.

Optionally, after the N + M third resources are determined, the N + M SR information may also be sent through the N + M third resources.

With reference to the above-mentioned modes A1 to A4, the sent SR information may be implicitly indicated by using the determined resource location information of the N + M third resources. That is, the N + M pieces of first information and the N + M pieces of second information are transmitted through the N + M pieces of third resources.

For example, when it is determined that the sent N + M SR information is positive, the N + M third resources may be determined by using the method A1, and each third resource carries corresponding SR information. When it is determined that N + M SR information to be transmitted is negative, N + M third resources may be determined in a manner A2, and each third resource carries corresponding SR information.

For another example, when it is determined that the sent N SR information is positive and the M SR information is negative, a mode A3 may be adopted to determine N + M third resources, and each third resource carries corresponding SR information. When it is determined that the sent M pieces of SR information are positive and the N pieces of SR information are negative, a manner A4 may be adopted to determine N + M pieces of third resources, and each third resource carries corresponding SR information.

Of course, the manner in which the N + M third resources transmit the N + M SR information may also be determined according to other manners, which is not limited herein.

For example, the first channel resources include 2 first resources, the second channel resources include 2 second resources, and the first TRP corresponds to 1 first resource and 1 second resource. The first TRP transmits 1 first UCI and 1 second UCI.

The second TRP corresponds to 1 first resource and 1 second resource. The second TRP transmits 1 first UCI and 1 second UCI.

Referring to fig. 7, the first UCI is HARQ information, and the second UCI is SR information. At this time, the first TRP transmits the 1 st HARQ information on the corresponding 1 st first resource, and the first TRP transmits the 2 nd SR information on the corresponding 2 nd second resource. The second TRP transmits the 2 nd HARQ information on the corresponding 2 nd first resource, and the second TRP transmits the 1 st SR information on the corresponding 1 st second resource.

At this time, 2 third resources may be determined among the 2 first resources and the 2 second resources, and used to transmit the 2 HARQ information.

The following illustrates, in combination with a possible collision, a manner of determining 2 third resources in the manners A1 to A4, including the following 5 possible scenarios:

1) Aliasing exists between the 1 st first resource and the 1 st second resource, and in this case, the 2 determined third resources may be:

mode A1, 1 st first resource and 2 nd first resource.

In conjunction with (a) of fig. 5a, as shown in (a) of fig. 7, at this time, r #11 and r #12 in the first channel resource may be taken as 2 third resources. Wherein the first TRP (TRP # 1) transmits the 1 st first UCI according to r #11 in the first channel resource. The second TRP (TRP # 2) transmits the 2 nd first UCI according to r #12 in the first channel resource.

Mode A2, the 1 st second resource and the 2 nd second resource.

In conjunction with (a) of fig. 5a, as shown in (b) of fig. 7, at this time, r #21 and r #22 of the second channel resources may be taken as 2 third resources. Wherein the first TRP (TRP # 1) transmits the 2 nd first UCI according to r #22 in the second channel resource. The second TRP (TRP # 2) transmits the 1 st first UCI according to r #21 in the second channel resource.

Mode A3, the 1 st first resource and the 2 nd second resource.

In conjunction with (a) of fig. 5a, as shown in (c) of fig. 7, at this time, r #21 in the second channel resource may be taken as the third resource of the second TRP, and r #12 in the first channel resource may be taken as the third resource of the first TRP. Wherein the first TRP (TRP # 1) transmits the 2 nd first UCI according to the quasi co-site relation of r #12 in the first channel resource.

The second TRP (TRP # 2) transmits the 1 st first UCI according to r #21 in the second channel resource.

Mode A4, 2 nd first resource and 1 st second resource.

In conjunction with (a) of fig. 5a, as shown in (d) of fig. 7, r #11 in the first channel resource may be used as a third resource of the first TRP, and r #22 in the second channel resource may be used as a third resource of the second TRP. Wherein the first TRP (TRP # 1) transmits the 1 st first UCI according to r #11 in the second channel resource. The second TRP (TRP # 2) transmits the 2 nd first UCI according to the quasi co-site relation of r #22 in the second channel resource.

Accordingly, the following description will exemplify modes B1 to B4 in conjunction with a scenario in which SR information is transmitted.

The method B1 selects the method A1 when the repeated SR information is determined to be positive and selects the method A2 when the repeated SR information is determined to be negative, in conjunction with a scenario in which the repeated SR information is transmitted.

The method B2 selects the method A2 when the repeated SR information is determined to be positive and selects the method A1 when the repeated SR information is determined to be negative, in conjunction with a scenario in which the repeated SR information is transmitted.

The mode B3 is selected when the repeated SR information is determined to be positive, and the mode A4 is selected when the repeated SR information is determined to be negative. Alternatively, the mode A4 is selected when the repeated SR information is determined to be positive, and the mode A3 is selected when the repeated SR information is determined to be negative.

And the mode B4, in combination with the scene of sending the non-repeated SR information, determining the selected mode A1-mode A4 according to the positive and negative time frequency resource position patterns (patterns) of the corresponding SR information.

For example, the mode A1 may be selected when the 1 st SR information and the 2 nd SR information are both determined to be positive, and the mode A2 may be selected when the 1 st SR information and the 2 nd SR information are both determined to be negative. The manner A3 is selected when it is determined that the 1 st SR information is positive and the second 2 SR information is negative. The mode A4 is selected upon determining that the 1 st SR information is negative and the 2 nd SR information is positive.

2) Aliasing exists between the 1 st first resource and the 2 nd second resource; at this time, the 2 third resources that can be determined may be: mode A1, the 1 st first resource and the 2 nd first resource. Mode A2, 1 st second resource and 2 nd second resource. Mode A3, the 1 st first resource and the 1 st second resource. Mode A4, 2 nd first resource and 2 nd second resource. Accordingly, in combination with a scenario of sending SR information, reference may be made to the above example, which is not described herein again.

3) Aliasing exists between the 1 st first resource and the 2 nd second resource; at this time, the 2 third resources that can be determined may be: mode A1, the 1 st first resource and the 2 nd first resource. Mode A2, the 1 st second resource and the 2 nd second resource. Mode A3, the 1 st first resource and the 1 st second resource. Mode A4, 2 nd first resource and 2 nd second resource. Accordingly, in combination with a scenario of sending SR information, reference may be made to the above example, which is not described herein again.

4) Aliasing exists between the 2 nd first resource and the 1 st second resource; at this time, the 2 third resources that can be determined may be: mode A1, 1 st first resource and 2 nd first resource. Mode A2, the 1 st second resource and the 2 nd second resource. Mode A3, 1 st first resource and 1 st second resource. Mode A4, 2 nd first resource and 2 nd second resource. Accordingly, in combination with a scenario of sending SR information, reference may be made to the above example, which is not described herein again.

5) Aliasing exists in the 1 st first resource and the 2 nd second resource, and aliasing exists in the 2 nd first resource and the 1 st second resource.

At this time, the 2 third resources that can be determined may be: mode A1, the 1 st first resource and the 2 nd first resource. Mode A2, the 1 st second resource and the 2 nd second resource. Accordingly, in combination with a scenario of sending SR information, reference may be made to the above example, which is not described herein again.

It should be noted that, the first channel resource and the second channel resource may be a set of resources within 1 slot, and in this case, the number of the first UCI and the number of the second UCI transmitted in one slot are equal. The first channel resource and the second channel resource may also be resource sets between time slots, and in this case, the number of first UCI correspondingly transmitted through the first channel resource between time slots is equal to the number of second UCI correspondingly transmitted through the second channel resource.

For another example, as shown in fig. 8a (a), the first channel resources include 3 first resources (r #11, r #12, r # 13), the second channel resources include 3 second resources (r #21, r #22, r # 23), and the first TRP corresponds to 1 first resource (e.g., r # 11) and 2 second resources (e.g., r #22, r # 23). The second TRP corresponds to 2 first resources (e.g., r #12, r # 13) and 1 second resource (e.g., r # 21). The first TRP transmits 1 first UCI and 2 second UCI. The second TRP transmits 2 first UCI and 1 second UCI.

Taking a scenario in which the 1 st first resource and the 1 st second resource have aliasing as an example, at this time, the 3 determined third resources may be:

mode A1: a1 st first resource, a2 nd first resource, and a 3rd first resource.

For example, as shown in (b) of FIG. 8a, the 3 third resources are r #11, r #12, r #13. The 1 st first UCI is transmitted on r #11 through a first TRP (TRP # 1). The 2 nd first UCI is transmitted on r #12 through the second TRP (TRP # 2), and the 3rd first UCI is transmitted on r #13 through the second TRP (TRP # 2).

Mode A2: a1 st second resource, a2 nd second resource, and a 3rd second resource.

For example, as shown in (c) of FIG. 8a, the 3 third resources are r #21, r #22, r #23. The 1 st first UCI is transmitted on r #11 through the second TRP (TRP # 2). The 2 nd first UCI is transmitted on r #22 through the first TRP (TRP # 1), and the 3rd first UCI is transmitted on r #23 through the first TRP (TRP # 1).

Mode A3: a1 st first resource, a2 nd first resource, and a 3rd second resource.

For example, as shown in (d) of FIG. 8a, the 3 third resources are r #11, r #22, r #13. The 1 st first UCI is transmitted on r #11 through the first TRP (TRP # 1), and the 2 nd first UCI is transmitted on r #22 through the first TRP (TRP # 1). The 3rd first UCI is transmitted on r #13 through the second TRP (TRP # 2).

Mode A4: a1 st first resource, a2 nd second resource, and a 3rd second resource.

For example, as shown in (e) of FIG. 8a, the 3 third resources are r #22, r #21, r #13. The 2 nd first UCI is transmitted on r #22 through the first TRP (TRP # 1), and the 1 st first UCI is transmitted on r #21 through the second TRP (TRP # 1). The 3rd first UCI is transmitted on r #13 through the second TRP (TRP # 2).

Of course, there may be other ways to select the third resource, which are not described herein again, and reference may be made to the way in fig. 7 specifically.

After the N + M third resources are determined, the corresponding manner for transmitting the HARQ information and the SR information may also be determined according to the format of the HARQ information transmitted on the first resource and the format of the SR information transmitted on the second resource.

Case 1, the format of the HARQ information on the first resource and the format of the SR information on the second resource are format 0. At this time, the transmitted HARQ information and SR information may be implicitly indicated by configuring different MCS parameters.

For example, in a scenario in which the repeated SR information is transmitted, the mode A1 is selected when the repeated SR information is determined to be positive, and the mode A2 is selected when the repeated SR information is determined to be negative, as shown in fig. 7.

The MCS parameters of the corresponding cyclic shift of the sequence when selecting the scheme A1 will be described in detail below.

Case 1.1, as shown in table 3, when the first PUCCH resource transmitting repeated 2 HARQ information uses format0 and the SR is a positive SR, the UE uses m when determining that the HARQ-ACK Value is 0 _CS =3, UE uses m when determining HARQ-ACK Value is 1 _CS =9, thus, the network device receives a pass m on the first channel resource _CS Where =3 encoded HARQ information, it may be determined that the value of HARQ is 0 and SR is positive. The network equipment receives the first channel resource through the m _CS =9 encoded HARQ information, it may be determined that the HARQ value is 1 and the SR is positive.

TABLE 3

Value of HARQ-ACK	0	1
			Sequence cyclic shift	m _CS ＝3	m _CS ＝9

Case 1.2, as shown in Table 4, when 2 non-repeated HARQ messages are transmitted and the first PUCCH resource usage format0, SR is positive, the UE uses m when determining HARQ-ACK Value as {0,0} _CS =1, UE uses m when determining HARQ-ACK Value to {0,1} _CS =4, thus, the network device receives a pass m on the first channel resource _CS =1 encoded HARQ information, it may be determined that the HARQ value is {0,0}, and the SR is positive. The network equipment receives the first channel resource through the m _CS Where =4 encoded HARQ information, it can be determined that the value of HARQ is {0,1}, and SR is positive. See table 4 for other scenarios, which are not described herein.

TABLE 4

Value of HARQ-ACK	{0,0}	{0,1}	{1,1}	{1,0}
					Sequence cyclic shift	m _CS ＝1	m _CS ＝4	m _CS ＝7	m _CS ＝10

Case 1.3, as shown in table 5, when the first PUCCH resource transmitting repeated 2 HARQ information uses format0 and SR is negative, the UE uses m when determining HARQ-ACK Value is 0 _CS =0,UE uses m when determining HARQ-ACK Value is 1 _CS =6, whereby the network device receives a connection through m on the first channel resource _CS Where =0 encoded HARQ information, it may be determined that the HARQ value is 0 and the SR is negative. The network equipment receives the first channel resource through the m _CS Where =6 encoded HARQ information, it may be determined that the value of HARQ is 1 and SR is negative.

TABLE 5

Value of HARQ-ACK	0	1
			Sequence cyclic shift	m _CS ＝0	m _CS ＝6

Case 1.4, as shown in table 6, when 2 non-repeated HARQ information are transmitted, and the first PUCCH resource uses format0, sr is positiveThe UE uses m when determining that the HARQ-ACK Value is 0,0 _CS =0, UE uses m when determining HARQ-ACK Value to {0,1} _CS =3, thus, the network device receives a pass m on the first channel resource _CS Where =0 encoded HARQ information, it can be determined that the value of HARQ is {0,0}, and SR is negative. The network equipment receives the first channel resource through the m _CS =3 encoded HARQ information, it may be determined that the HARQ value is {0,1}, and SR is negative. See table 6 for other scenarios, which are not described herein.

TABLE 6

Value of HARQ-ACK	{0,0}	{0,1}	{1,1}	{1,0}
					Sequence cyclic shift	m _CS ＝0	m _CS ＝3	m _CS ＝6	m _CS ＝9

In case 2, the format of the HARQ information on the first resource is format 1, and the format of the SR information on the second resource is format 0. At this time, the terminal may send the N + M HARQ information on the N + M third resources through the corresponding formats, and accordingly, the network device may determine the N + M HARQ information on the N + M third resources through the corresponding formats. For the SR information, the SR information may be implicitly indicated by selecting different N + M third resources.

In connection with the example in fig. 7, HARQ information and SR information may be transmitted with reference to the modes B1 to B4. This is illustrated below in the manner B1.

In conjunction with a scenario in which repeated SR information is transmitted, for example, as shown in fig. 9, in conjunction with a method B2, a method A2 is selected when the repeated SR information is determined to be positive, and HARQ is transmitted on the repeated resources of all SRs; the method A1 is selected when the repeated SR information is determined to be negative, i.e., HARQ is transmitted on all HARQ repetition resources.

Considering that the UE may transmit 2 HARQ information in the format 1 manner on 2 first resources when selecting the manner A1, the SR information may be ignored and indicated in an implicit manner. In selecting the mode A2, the UE may transmit HARQ & SR joint coding information using format0 on 2 second resources. Specifically, reference may be made to the example in case 1 above, and details are not described here.

Case 3, the format of the HARQ information on the first resource, and the format of the SR information on the second resource are all format 1. At this time, the terminal may send the N + M HARQ information on the N + M third resources through format 1, and accordingly, the network device may determine the N + M HARQ information on the N + M third resources through format 1. For the SR information, the SR information may be implicitly indicated by selecting different N + M third resources.

In connection with the example in fig. 7, HARQ information and SR information may be transmitted with reference to the modes B1 to B4. This is illustrated below in the manner B1. In a scenario in which duplicate SR information is transmitted, for example, in connection with the method B1, the method A1 is selected when the duplicate SR information is determined to be positive, and the method A2 is selected when the duplicate SR information is determined to be negative.

And in case 4, the format of the HARQ information on the first resource is format 2/3/4, and the format of the SR information on the second resource is format 2/3/4. At this time, the terminal may send the N + M HARQ information and the N + M SR information on the N + M third resources through format 1, and accordingly, the network device may determine the N + M HARQ information and the N + M SR information on the N + M third resources through format 1.

In a scenario of transmitting the repeated HARQ and transmitting the repeated SR information, the SR information and the HARQ information may be transmitted through multiplexing on the determined N + M third resources. For example, SR information may be added after HARQ information for joint coding. The length of the SR information may be

K is the number of PUCCH resources of the time-domain aliased SR, and the SR information value means the several SR of all K aliased SRs.

In connection with the example in fig. 7, HARQ information and SR information may be transmitted with reference to the modes B1 to B4. This is illustrated below in the manner B1. In a scenario in which duplicate SR information is transmitted, for example, in connection with the scheme B1, the scheme A1 is selected when the duplicate SR information is determined to be positive, and the scheme A2 is selected when the duplicate SR information is determined to be negative.

Scenario 1.2, the number of the first resource in the first channel resource and the second resource in the second channel resource are not equal. At this time, the number of first UCI transmitted on a first resource among the first channel resources is not equal to the number of second UCI transmitted on a second resource among the second channel resources.

At this time, N + M third resources may be determined according to transmission characteristics of the first UCI and the second UCI.

In one possible implementation manner, the first UCI is HARQ information, and the second UCI is SR information. The SR information may determine whether a value of the currently transmitted SR information is positive or negative by transmitting a pattern of resources corresponding to different first UCI. Therefore, when the SR information is determined to be positive, a manner of transmitting the first UCI using the N + M third resources may be correspondingly selected. And correspondingly selecting another mode of transmitting the first UCI by the N + M third resources when the SR information is determined to be negative.

Next, as shown in fig. 8b (a), 2 first resources (r #11 and r # 12) are included in the first channel resource, 1 second resource (r # 2) is included in the second channel resource, and the first TRP corresponds to the 1 st first resource (r # 11). The second TRP corresponds to the 1 st first resource (r # 12) and the 1 st second resource (r # 2). r #11 and r #2 collide. After determining that the collision occurs, the first UCI transmitted on the second resource (r # 2) may be determined as shown in (b) of fig. 8b when the SR information is determined to be positive. When it is determined that the SR information is negative, as shown in (c) of fig. 8b, the first UCI is transmitted on the first resources (r #12 and r # 11).

For another example, as shown in fig. 8c (a), the second channel resources include 2 second resources (r #21 and r # 22), the first channel resources include 1 second resource (r # 1), and the second TRP corresponds to the 1 st second resource (r # 21). The first TRP corresponds to the 1 st first resource (r # 1) and the 1 second resource (r # 22). r #1 and r #22 collide. Discarding the few or non-repeated ones after determining that the collision occurred. Accordingly, the first UCI transmitted on the first resource (r # 1) may be determined to be positive when the SR information is determined to be positive, as shown in (b) of fig. 8 c. When it is determined that the SR information is negative, as shown in (c) of fig. 8c, a second UCI transmitted on a second resource (r #22 and r # 21).

According to the embodiment, the problem that the gain of the space diversity disappears under the condition that the PUCCH in the MTRP scene is repeatedly sent is solved by determining that any resource in the resource set is collided and multiplexing all the resources in the resource set.

Example two

The number of first resources in the first channel resources and the number of second resources in the second channel resources are not equal. At this time, the number of first UCI transmitted on a first resource among the first channel resources is not equal to the number of second UCI transmitted on a second resource among the second channel resources.

In a possible implementation manner, R of the K third resources are fourth resources (e.g., may be virtual first resources hereinafter) determined according to the first channel resources, and the fourth resources are different from the first resources in the first channel resources. R is less than or equal to N, and/or S of the K third resources are fourth resources determined according to the second channel resources, for example, may be virtual second resources hereinafter), and the fourth resources are different from the second resources in the second channel resources. Said S is less than or equal to said N; and R and S are non-negative integers. Wherein the virtual first resource or virtual second resource is predefined, or semi-statically configured, or dynamically configured. The virtual first resources are different from N1 first resources of the first channel resources; the virtual second resources are different from the M1 first resources in the second channel resources.

And establishing virtual first resources or virtual second resources to enable the number of the resources in the increased first channel resources and the second channel resources to be equal, or enable the number of the resources in the first channel resources and the increased second channel resources to be equal.

Considering that the amounts of the first resource and the second resource are not equal, two cases are mainly used, and the scenario 2.1 and the scenario 2.2 are illustrated below.

In scenario 2.1, the number of HARQ information correspondingly transmitted on the first channel resource is greater than the number of SR information correspondingly transmitted on the second channel resource.

At this time, N + M is the number of HARQ information correspondingly transmitted on the first channel resource, that is, the first channel resource includes N + M first resources. At this time, considering that the number of the transmitted SR information is less than N + M, for example, the difference is L, L virtual second resources may be added to the second channel resources, so that the added second channel resources include N + M-L second resources and L virtual second resources. Thus, N + M first resources, second resources, or virtual second resources may be selected from the first channel resources and the added second channel resources as N + M third resources.

The L virtual second resources may be resources having an association relationship with the N + M-L second resources, or second resources determined according to other manners, or determined based on a quasi-co-site relationship of the N + M first resources, which is not limited herein. The virtual second resource is used only for collision processing. The initial position of the time-frequency resource of the virtual second resource can be configured by the base station, and the configuration mode can adopt an absolute resource mode or a mode of transmitting the resource relatively to the actual mode. The spatial relationship of the configuration or indication of the virtual second resource is different from the N + M-L second resources; the other configuration may be the same second resource that the virtual second resource has an association with.

At this time, the N third resources are first resources allocated to the first TRP; the M third resources are second resources allocated to the second TRP.

The specific selection manner may refer to manner A1 to manner A4, which is not described herein again.

Accordingly, considering that the number of transmitted SR information is less than N + M, at this time, N + M SR information may be transmitted based on the determined N + M third resources. It can be seen that in this scheme, more L SR information is transmitted than when there is no collision. It should be noted that the SR information sent on the virtual second resource may determine the filled SR information according to a preset rule, and there may be multiple implementation manners, which is not limited herein.

For example, when a repeated PUCCH (PUCCH repetition) of 2 times of repeated UCI and a non-repeated PUCCH (Single PUCCH) transmission of one non-repeated UCI are transmitted, as shown in fig. 9 (a), 2 first resources (r #11 and r # 12) are included in the first channel resource, 1 second resource (r # 2) is included in the second channel resource, and the first TRP corresponds to the 1 st first resource (r # 11). The second TRP corresponds to the 1 st first resource (r # 12) and the 1 st second resource (r # 2). When there is the following transmission resource aliasing scheme, taking 2 repetitions as an example, the possible collision situations may include:

1) Aliasing exists between the 1 st first resource repetition #1 (r # 11) in the first PUCCH resource set and the second resource (r # 2) in the second PUCCH resource set (Single PUCCH);

2) Aliasing exists between the 2 nd first resource repetition #2 (r # 12) in the first PUCCH resource set and the second resource (r # 2) in the second PUCCH resource set (Single PUCCH).

At this time, one or more virtual transmission resources may be configured for the Single PUCCH, for example, as shown in (c) of fig. 9, 1 virtual second resource (r # 2') may be added correspondingly, corresponding to the first TRP. The virtual second resource may be determined according to the quasi co-site relationship of r #12, or may be determined in other manners, which is not limited herein.

In this case, in combination with scheme A1, 2 HARQ information and 2 SR information may be transmitted on 2 first resources, respectively. That is, the first TRP transmits 1 HARQ information and 1 SR information on the 1 st first resource. The second TRP transmits 1 HARQ information and 1 SR information on the 2 nd first resource.

With reference to the method A2, 2 HARQ information and 2 SR information may be respectively transmitted on 1 second resource and 1 virtual second resource. That is, the first TRP transmits 1 HARQ information and 1 SR information on 1 virtual second resource. The second TRP transmits 1 HARQ information and 1 SR information on 1 second resource.

Taking format 1 as an example of transmitting duplicate HARQ information and transmitting non-duplicate SR information, in this case, virtual (virtual) duplicate SR information (SR PF1 repetition) may be added to the non-duplicate SR information: the virtual repeated SR information may collide with the HARQ retransmission FR1 that does not collide, and the collision problem may be solved by the mode B1 or the mode B2. That is, when the SR information is positive, transmitting HARQ information repeated 2 times on the second resource and the virtual second resource; when the SR information is negative, 2-time repeated HARQ information is transmitted on the first resource.

For another example, the first channel resources include 4 first resources, the second channel resources include 2 second resources, and the first TRP includes 2 first resources and 1 second resource. The second TRP includes 2 first resources and 1 second resource.

In this case, in combination with scheme A1, 4 HARQ information and 4 SR information may be transmitted on 4 first resources, respectively. That is, the first TRP transmits 1 HARQ information and 1 SR information on the 1 st first resource, and the first TRP transmits 1 HARQ information and 1 SR information on the 2 nd first resource. The second TRP transmits 1 HARQ information and 1 SR information on the 3rd first resource, and the second TRP transmits 1 HARQ information and 1 SR information on the 4 th first resource.

With reference to the method A2, 4 pieces of HARQ information and 4 pieces of SR information may be transmitted on 2 second resources and 2 virtual second resources, respectively. That is, the first TRP transmits 1 HARQ information and 1 SR information on the 1 st virtual second resource, and the first TRP transmits 1 HARQ information and 1 SR information on the 2 nd virtual second resource. The second TRP transmits 1 HARQ information and 1 SR information on the 1 st second resource, and the second TRP transmits 1 HARQ information and 1 SR information on the 2 nd second resource.

In scenario 2.2, the number of HARQ information correspondingly transmitted on the first channel resource is smaller than the number of SR information correspondingly transmitted on the second channel resource.

At this time, N + M is the number of SR information correspondingly transmitted on the second channel resource, that is, the number of the first channel resources included on the first channel resource is less than N + M. For example, the difference is L. At this time, considering that the number of the transmitted HRAQ messages is less than N + M, L virtual first resources may be added to the first channel resources, so that the added first channel resources include N + M-L first resources and L virtual first resources. Thus, N + M first resources, second resources, or virtual first resources may be selected as the N + M third resources from among the second channel resources and the added first channel resources.

The specific selection manner may refer to manner A1 to manner A4, which is not described herein again. Accordingly, considering that the number of transmitted SR information is equal to N + M, at this time, N + M SR information may be transmitted based on the determined N + M third resources. For a specific selection manner, reference may be made to manner B1 to manner B4, which are not described herein again. It should be noted that the HARQ information sent on the virtual first resource may determine the filled HARQ information according to a preset rule, and there may be multiple implementation manners, which is not limited herein. It can be seen that in this scheme, more L HARQ information are transmitted than when there is no collision.

For another example, as shown in fig. 9 (b), the second channel resources include 2 second resources (r #21 and r # 22), the first channel resources include 1 second resource (r # 1), and the second TRP corresponds to the 1 st second resource (r # 21). The first TRP corresponds to the 1 st first resource (r # 1) and the 1 st second resource (r # 22).

At this time, one or more fourth resources (virtual transmission resources) may be configured for the Single PUCCH, for example, as shown in (d) of fig. 9, 1 virtual first resource (r # 1') may be added correspondingly, corresponding to the second TRP. The virtual second resource may be determined according to the quasi co-sited relationship of r #22. The determination may also be made in other ways, and is not limited herein.

Taking format 1 for example of transmitting repeated SR information and transmitting non-repeated HARQ information, in this case, a fourth resource may be added for the non-repeated HARQ information, for example, the fourth resource may be additionally added repeated HARQ information (HARQ PF1 repetition), and in one possible implementation manner, the repeated HARQ information of the fourth resource may collide with the non-colliding SR repetition FR1, and the collision problem may be solved by the manner B1 or the manner B2. That is, when the SR information is positive, 2 times of repeated HARQ information is transmitted on the second resource; when the SR information is negative, 2-time repeated HARQ information is transmitted on the first resource and the virtual first resource.

The specific implementation manner may refer to scenario 1, which is not described herein again.

The L virtual first resources may be resources having a quasi co-site relationship with the N + M-L first resources, or may be virtual first resources determined according to other manners. The virtual first resource is used only for collision processing. The initial position of the time-frequency resource of the virtual first resource can be configured by the base station, and the configuration mode can adopt an absolute resource mode and can also adopt a mode of transmitting the resource relatively actually. The spatial relationship of the configuration or indication of the virtual first resource is different from the N + M-L second resources; the other configuration may be the same as the first resource associated with the virtual first resource.

For the fourth resource (virtual first resource and virtual second resource), the fourth resource may be predefined, or semi-statically configured, or dynamically configured. The partial resource attributes may be the same as the corresponding actual transmission resources, time-frequency domain resource allocation (period and offset) of slot granularity, initial symbol index in the slot, duration, initial physical resource block index, number of occupied physical resource blocks, and the like. In addition, the resource attribute of the fourth resource may also be that the base station is configured independently of the corresponding first resource and second resource. The start of the time-frequency resource may be configured by the base station, and the configuration may be in an absolute resource manner, or in a manner of using a relative first resource or a relative second resource (for example, there is an offset between the time-frequency domain and the first resource or the second resource). The configured or indicated spatial relationship is different from the corresponding first resource and second resource.

By defining the fourth resource, the number of the resource sets is equal, or the resource formats in the resource sets with collision are equal, so that the collision can be processed based on the first example, and a uniform compatible collision and processing scheme is realized. And the multiplexing rule is adopted as much as possible, so that the performance loss caused by adopting the discarding is reduced.

Example three

In this example, the processing may be performed separately for the collided resource and the non-collided resource. At this time, for the resource which does not have a collision, the quasi-co-site relationship of the ith third resource in the K third resources is determined according to at least one of the following: the method comprises the steps that at least one first resource, at least one second resource, the quasi-co-site relation of the jth third resource in the K third resources, the quasi-co-site relation of at least one first resource and the quasi-co-site relation of at least one second resource are obtained; and the i and the j are positive integers less than or equal to K.

In one possible implementation, a corresponding number of third resources may be determined based on the first resource and the second resource that have collided. For example, among N1 first resources and N1 second resources in which a collision occurs, N1 third resources are determined, where N1 is a positive integer smaller than N1 and smaller than M1.

In some embodiments, for n1 first and second resources that collide: determining a kth third resource according to the a-th first resource and the b-th second resource; the kth third resource is the a-th first resource or the b-th second resource. a, b and k are positive integers; k is less than or equal to n1.

For a specific manner of determining the n1 third resources, reference may be made to manner A1 to manner A4 in example one. For example, when the kth third resource is one of the N third resources, at least one of the M third resources is at least one first resource of the first channel resources; and/or, when the kth third resource is one of the M third resources, at least one of the N third resources is at least one of the second channel resources.

For example, as shown in (a) of fig. 10, 2 first resources (r #11 and r # 12) are included in the first channel resource, 1 second resource (r # 2) is included in the second channel resource, and the first TRP corresponds to the 1 st first resource (r # 11). The second TRP corresponds to the 1 st first resource (r # 12) and the 1 st second resource (r # 2). r #11 and r #2 collide.

At this time, as shown in (a) of fig. 10, the 1 st third resource may be determined to be r #2 from r #11 and r #2. Alternatively, the 1 st third resource may be determined to be r #11 from r #11 and r #2.

For the first resource and the second resource which do not collide, N + M-N1 third resources may be determined according to the determined channel spatial relationship of the N1 third resources and the first resource and the second resource which do not collide, so that the first TRP corresponds to the N third resources, and the second TRP corresponds to the M third resources. I.e. part of the channels or all of the channels that are not collided use the channel spatial relationship of the collision. Therefore, after resource collision is avoided, the space diversity performance under a multi-TRP architecture can still be ensured.

Two scenarios 3.1 to 3.2 are exemplified below:

scene 3.1: at least one of the N third resources is determined according to a quasi co-site relationship of the at least one first resource or the at least one second resource.

For example, format 1 is taken as an example to transmit repeated HARQ information and SR information that does not repeat, for example, the HARQ information is transmitted under URLLC traffic and the SR information is transmitted under eMBB traffic. As shown in (a) of fig. 10, at this time, the 1 st HARQ information may be transmitted through the first TRP on the first resource (r # 11) and the 2 nd HARQ information may be transmitted through the second TRP on the first resource (r # 12) when the SR information is negative. As shown in fig. 10 (c), when the SR information is positive, the HARQ (1 st HARQ information) having a collision is transmitted through the second TRP on the second resource (r # 2), and the HARQ information (2 nd HARQ information) not having a collision is transmitted through the first TRP according to the quasi co-site relationship of the first resource (r # 12) corresponding to the 2 nd HARQ information.

Scene 3.2: at least one of the M third resources is determined according to a quasi co-site relationship of the at least one first resource or the at least one second resource.

As shown in fig. 10 (b), 2 second resources (r #21 and r # 22) are included in the second channel resources, 1 second resource (r # 1) is included in the first channel resources, and the second TRP corresponds to the 1 st second resource (r # 21). The first TRP corresponds to the 1 st first resource (r # 1) and the 1 second resource (r # 22). r #1 and r #22 collide.

Taking format 1 as an example, the SR information is transmitted under URLLC traffic and the HARQ information is transmitted based on eMBB traffic, where the SR information is transmitted repeatedly (here, the second UCI) and the HARQ information is not transmitted repeatedly (here, the first UCI).

One possible implementation, in conjunction with (b) of fig. 10, may be to transmit the 1 st HARQ information on the second resource (r # 21) through the first TRP and transmit the 2 nd HARQ information on the second resource (r # 22) through the second TRP when the SR information is negative. With reference to fig. 10 (d), when the SR information is positive, the HARQ (2 nd HARQ information) that has collided is transmitted through the first TRP on the first resource (r # 1), and the HARQ information (1 st HARQ information) that has not collided is transmitted through the second TRP according to the quasi-co-site relationship of the second resource (r # 21) corresponding to the 1 st HARQ information.

By changing the quasi-common-site relation of the non-collision PUCCH resources, the problem that space diversity gain possibly disappears caused by collision problem in the prior art is solved; in addition, the system performance is improved by adopting a mode of multiplexing and sending the first information and the second information.

Example four

In this example, after it is determined that a collision occurs, the UCI that is not repeatedly transmitted or has a small number of repetitions may be discarded based on a discarding manner, that is, N + M third resources are determined according to the first resource or the second resource corresponding to the UCI having a large number of repetitions.

One possible implementation manner may be that when it is determined that the number of repetitions of the first UCI transmitted through the first channel resource is greater than the number of repetitions of the second UCI transmitted through the second channel resource, N + M third resources are determined through N + M first resources in the first channel resources.

In some embodiments, the terminal device may determine, according to configuration information of the number of repetitions of a first UCI transmitted by a first channel resource and configuration information of the number of repetitions of a second UCI transmitted by a second channel resource, that the number of repetitions of the first UCI transmitted by the first channel resource is greater than the number of repetitions of the second UCI transmitted by the second channel resource.

For example, N + M third resources may be determined through N + M first resources among the first channel resources when it is determined that the number of repetitions of the first UCI transmitted through the first channel resources is greater than the number of repetitions of the second UCI transmitted through the second channel resources.

In some embodiments, upon determining that a number of repetitions of a first UCI transmitted over the first channel resource is less than a number of repetitions of a second UCI transmitted over the second channel resource, canceling transmission of a corresponding first UCI on at least a first resource with resource aliasing between the at least one second resource of a second channel resource;

it should be noted that the cancellation mode may be ignoring (drop), or may be a first UCI corresponding to at least a first resource that does not transmit a resource alias with at least one second resource of the second channel resources.

At this time, N + M third resources may be determined by N + M first resources among the first channel resources with which there is no resource aliasing with at least one first resource of the first channel resources; the N + M third resources are used for transmitting the first UCI corresponding to the N + M first resources.

For example, in one timeslot, when it is determined that the number of the repeated HARQ information corresponding to the first channel resource is greater than the number of the repeated SR information corresponding to the second channel resource, the SR information is cancelled or not transmitted. Taking the number of the repeated HARQ information corresponding to the first channel resource as N + M as an example, N + M first resources corresponding to the first channel resource are determined as N + M third resources, and the N + M third resources are used for transmitting the N + M HARQ information.

In still other embodiments, upon determining that a number of repetitions of a first UCI transmitted over the first channel resource is less than a number of repetitions of a second UCI transmitted over the second channel resource, transmitting a corresponding second UCI on at least one of the second channel resources.

For another example, in one timeslot, when it is determined that the number of the repeated HARQ information corresponding to the first channel resource is smaller than the number of the repeated SR information corresponding to the second channel resource, the HARQ information is cancelled or not transmitted. Taking the number of the repeated SR information sent by the second channel resource as N + M as an example, N + M second resources corresponding to the second channel resource are determined as N + M third resources, and the N + M third resources are used for sending N + M SR information.

For example, as shown in fig. 11 (a), 2 first resources (r #11 and r # 12) are included in the first channel resource, 1 second resource (r # 2) is included in the second channel resource, and the first TRP corresponds to the 1 st first resource (r # 11). The second TRP corresponds to the 1 st first resource (r # 12) and the 1 st second resource (r # 2). r #11 and r #2 collide. Discarding the few or non-repeated ones after determining that the collision occurred. Accordingly, the second UCI transmitted on the second resource (r # 2) may be discarded as shown in (c) of fig. 11.

For another example, as shown in fig. 11 (b), the second channel resources include 2 second resources (r #21 and r # 22), the first channel resources include 1 second resource (r # 1), and the second TRP corresponds to the 1 st second resource (r # 21). The first TRP corresponds to the 1 st first resource (r # 1) and the 1 second resource (r # 22). r #1 and r #22 collide. Discarding the few or non-repeated ones after determining that the collision occurred. Accordingly, the first UCI transmitted on the first resource (r # 1) may be discarded as shown in (d) of fig. 11.

By the method, the collision can be discarded according to the judgment mode of the repeated times under the condition of any collision, the complexity of collision processing is simplified, the UCI does not need to be set with a complex priority, the time delay of data transmission is reduced, and the transmission performance of the system is improved.

In consideration of the fact that there is a collision between the first information and the second information transmitted on the same TRP, there may be a scenario in which a first resource corresponding to the first information and a second resource corresponding to the second information collide. For example, as shown in fig. 12, the first channel resources include N1 first resources, the second channel resources include M1 second resources, a first resource 1 exists in the N1 first resources, and a second resource 2 exists in the M1 second resources, where the first resource 1 transmits first information of the terminal through the first TRP, and the second resource 2 transmits second information of the terminal through the first TRP. Wherein the first information and/or the second information may be the repeatedly transmitted information in the above.

In one possible scenario, the time-frequency resources of the first resource 1 and the second resource 2 may collide. In addition, there may also be a collision between the first resource and the second resource on different TRPs (e.g., as shown in fig. 12, a collision of the first resource 1 and the second resource 1). At this time, the first resource and the second resource that have collided with each other on the same TRP may be processed first to obtain the processed first resource and the processed second resource, so that the processed first resource and the processed second resource have no collision on the same TRP. When a collision occurs between resources on different TRPs on the processed first resource and the processed second resource, the processed first resource and the processed second resource may be processed in a manner described above with reference to fig. 6a to 6b to obtain a third resource, and corresponding first information and/or second information is sent through the third resource. Or, in the manner shown in fig. 6a to fig. 6b, the first resource and the second resource in the first channel resource and the second channel resource that transmit the repeated data are processed first, so as to obtain N + M third resources, and then the third resource that has the same TRP and is collided with the N + M third resources is processed. The following is exemplified by a manner of processing a first resource and a second resource that have collided on the same TRP.

For the problem that the first resource and the second resource on the same TRP of the time slot level collide, the PUCCH resource of the format 1/3/4 is used for the first resource and the second resource, and the PUCCH resource can be repeatedly transmitted at the time slot level. When collision exists on one or more time slots by using the PUCCH resources repeatedly transmitted at a time slot level and one or more PUCCH resources repeatedly transmitted at a non-repeated transmission or time slot level, the collision resources are processed by adopting the following mode for each collision resource: according to the priority of the UCI type, for example, the priority may be: HARQ > SR > high-priority CSI > low-priority CSI, and at the moment, for UCI types of the same priority, repeated instances which cannot be initiated by the repeated transmission of the collided PUCCH controlled by the base station cannot be in the same time slot; for the UCI types with the same priority, the terminal sends an earlier PUCCH and discards the sent PUCCH; for PUCCH repeated instances with collision of UCI types of different priorities, the terminal sends repeated UCI on the PUCCH with high priority and discards repeated UCI of the PUCCH with low priority; and for the non-collided PUCCH repeated examples, collision processing is not carried out, and the transmission is continued. Namely, in this scenario, the terminal does not reuse UCI of different types, and the collision problem is solved by discarding the UCI.

In another possible implementation manner, for the problem of collision between the first resource and the second resource on the same TRP in the timeslot, reference may be made to a processing scheme for the collided first resource and second resource when the first resource and the second resource on different TRPs collide in example three. Of course, the processing may be performed by other methods, which are not limited herein.

One possible implementation manner may be to configure, for the problem that the first resource and the second resource on the same TRP collide, the priority of the PUCCH carrying the HARQ may be configured to be the priority 0 and the priority 1, and the priority of the PUCCH carrying the SR may be configured to be the priority 0 and the priority 1, for example, based on the priority of the physical channel corresponding to the first resource and the second resource. At this time, information on the resource of high priority may be transmitted according to the priority of the first resource and the priority of the second resource. For example, when the priority of the first resource is higher than the priority of the second resource, the first information on the first resource is transmitted, and the transmission of the second information on the second resource is discarded. When the priorities of the first resource and the second resource are the same, the processing may be performed according to the processing manner for the resource with resource collision in example three or other manners, which is not described herein again.
