Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a data transmission method and related equipment. Background Technology

[0002] Uplink Control Information (UCI) multiplexing refers to the process in the 3GPP NR protocol of merging uplink control information from multiple uplink physical control channels (PUCCH) into a single uplink physical control channel for transmission when the uplink physical control channels (PUCCH) for transmitting uplink control information overlap in the time domain.

[0003] The current 3GPP NR protocol defines multiplexing rules among three types of uplink control information: Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK), Channel State Information Report (CSI report), and Scheduling Request (SR) to achieve data transmission. However, if a new type of uplink control information is introduced during data transmission, the current uplink control information multiplexing rules cannot accommodate the addition of a new uplink control signaling type, thus preventing the User Equipment (UE) from processing and transmitting the uplink control signaling. Summary of the Invention

[0004] This application provides a data transmission method and related equipment.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, embodiments of this application provide a data transmission method, which involves acquiring uplink control information to be transmitted; the uplink control information to be transmitted includes at least one of Hybrid Automatic Repeat Request Acknowledgment, Channel State Information Report, and Scheduling Request, as well as a first channel indication; and determining at least one uplink control information and uplink physical control channel resources for carrying at least one uplink control information from the uplink control information to be transmitted according to the multiplexing rules corresponding to the uplink control information to be transmitted; the multiplexing rules include multiplexing rules between at least one of HARQ-ACK, CSI report, and SR and the first channel indication, wherein the multiplexing rules between other SRs (excluding positive Link Recovery Request (LRR)) and the first channel indication include determining the uplink control information with a positive state and the earliest start time slot from the other SRs and the first channel indication; and transmitting at least one uplink control information based on the uplink physical control channel resources.

[0007] In this embodiment, the multiplexing rules for uplink control information are updated. When a new type of uplink control information exists, the uplink control information can be transmitted based on the updated multiplexing rules. The new type of uplink control information is a first channel indication, which is used to instruct the terminal device to initiate and / or perform event-driven beam report transmission procedures. The priority of the first channel indication is lower than that of a positive LRR in the SR, the priority of a positive LRR is lower than that of HARQ-ACK, and the priority of other SRs is higher than that of CSI report.

[0008] In one possible implementation, when the uplink control information to be transmitted includes a first channel indication and an SR, according to the multiplexing rules between the first channel indication and the SR, when the uplink physical control channel format of the first channel indication is 0, the first channel indication is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying at least one uplink control information is determined as the uplink physical control channel resource of the first channel indication.

[0009] When the uplink physical control channel format of the first channel indication is 1 and the uplink physical control channel format of the SR is 0, a higher priority uplink control information is determined from the SR and the first channel indication according to the priority between the SR and the first channel indication, and the uplink physical control channel resource used to carry the higher priority uplink control information is determined to be the uplink physical control channel resource of the first channel indication.

[0010] When the uplink physical control channel resource of the first channel indication is 1 and the uplink physical control channel format of the SR is 1, in the case of a positive SR, the first channel indication is determined from the uplink control information to be transmitted, and the uplink physical control channel resource used to carry at least one uplink control information is determined as the uplink physical control channel resource of the SR; in the case of a negative SR, the first channel indication is determined from the uplink control information to be transmitted, and the uplink physical control channel resource used to carry at least one uplink control information is determined as the uplink physical control channel resource of the first channel indication.

[0011] In one possible implementation, when the uplink control information to be transmitted includes a first channel indication and a Service Request (SR), according to the multiplexing rules between the first channel indication and the SR, if the uplink physical control channel resource of the first channel indication is 1 and the uplink physical control channel format of the SR is 1, the starting timeslots of the first channel indication and the SR are compared; the one with the earlier starting timeslot is determined as the uplink control information from the first channel indication and the SR. If the starting timeslots of the two are the same, either one is randomly selected, either according to a predefined rule or according to the network-side configuration, and one of them is selected as the uplink control information to be sent.

[0012] In one possible implementation, when the uplink control information to be transmitted includes a first channel indication, HARQ-ACK, and SR, conflict resolution is performed on the first channel indication and SR according to the multiplexing rules among the first channel indication, HARQ-ACK, and SR. An uplink physical control channel resource is determined from the uplink physical control channel resources of the first channel indication and the uplink physical control channel resources of the SR as the first uplink physical control channel resource. When the uplink physical control channel format of HARQ-ACK is 0, HARQ-ACK is determined from the uplink control information to be transmitted, and the uplink physical control channel resource used to carry HARQ-ACK is determined as the uplink physical control channel resource of HARQ-ACK. When the uplink physical control channel format of HARQ-ACK is 1, and the format of the first uplink physical control channel is 1, and the first uplink physical control channel corresponds to positive uplink control information, HARQ-ACK is determined from the uplink control information to be transmitted, and the uplink physical control channel resource used to carry HARQ-ACK is determined as the first uplink physical control channel resource.

[0013] In one possible implementation, when the uplink control information to be transmitted includes at least one of HARQ-ACK and CSI report, a first channel indication, and SR, an uplink control information is determined from the first channel indication and SR; based on the multiplexing rules between the uplink control information determined from the first channel indication and SR and HARQ-ACK and CSI report, at least one uplink control information and uplink physical control channel resources for carrying at least one uplink control information are determined from the uplink control information determined from the first channel indication and SR, HARQ-ACK, and CSI report.

[0014] In one possible implementation, when the uplink control information to be transmitted includes a first channel indication, a CSI report, and an SR, and when the uplink physical control channel format of the CSI report is at least one of 2, 3, and 4, based on the priority of the uplink control information to be transmitted and the upper limit of the number of bits supported by the uplink physical control channel resources of the CSI report, a first-bit number of the first channel indication, a second-bit number of the CSI report, and a third-bit number of the SR are determined from the uplink control information to be transmitted, and the uplink physical control channel resources used to carry the uplink control information are determined to be the uplink physical control channel resources of the CSI report; the first-bit number of the first channel indication, the second-bit number of the CSI report, and the third-bit number of the SR are transmitted based on the uplink physical control channel resources of the CSI report; or, the first-bit number of the first channel indication and the third-bit number of the SR are jointly encoded to obtain a fourth-bit number of jointly encoded information; the second-bit number of the CSI report and the fourth-bit number of jointly encoded information are transmitted based on the uplink physical control channel resources of the CSI report.

[0015] In one possible implementation, when the uplink control information to be transmitted includes a first channel indication, HARQ-ACK, CSI report, and SR, the fifth bit of HARQ-ACK, the sixth bit of SR, the seventh bit of the first channel indication, and the eighth bit of CSI report are determined from the uplink control information to be transmitted based on the priorities of HARQ-ACK, SR, the first channel indication, and CSI report, as well as the upper limit of the number of bits supported by the uplink physical control channel resources; and based on the uplink physical control channel resources, the fifth bit of HARQ-ACK, the sixth bit of SR, the seventh bit of the first channel indication, and the eighth bit of CSI report are transmitted.

[0016] In one possible implementation, when the uplink control information to be transmitted includes a positive first channel indication, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources that do not carry uplink shared channel data, the physical uplink shared channel resources are discarded, and the uplink control information is transmitted based on the uplink physical control channel resources.

[0017] In one possible implementation, when the uplink control information to be transmitted includes a positive first channel indication, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources carrying uplink shared channel data, the physical uplink shared channel resources of the uplink control information to be transmitted are discarded, and the physical uplink shared channel resources are transmitted.

[0018] In one possible implementation, when the uplink control information to be transmitted includes a positive first channel indication and a positive SR, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources that do not carry uplink shared channel data, the physical uplink shared channel resources are discarded, and the uplink physical control channel resources of the uplink control information are transmitted.

[0019] In one possible implementation, when the uplink control information to be transmitted includes a positive first channel indication and a positive SR, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources carrying uplink shared channel data, the uplink physical control channel resources of the uplink control information are discarded, and the physical uplink shared channel resources are transmitted.

[0026] The terms "first," "second," and "third," etc., used in this application specification, claims, and drawings are used to distinguish different objects, not to limit a specific order.

[0027] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0028] The technical concepts in the embodiments of this application will be introduced for ease of understanding.

[0029] The Physical Uplink Control Channel (PUCCH) is a physical channel used to transmit UCI. It supports multiple transmission formats, and different formats determine different numbers of bits and the symbol length of the Orthogonal Frequency Division Multiplexing (OFDM) technique.

[0030] The Physical Uplink Shared Channel (PUSCH) is used to carry uplink data transmission from terminal devices to network devices. When a terminal device has data to send (such as voice, video, or other data), this data can be sent to the network device through the PUSCH. The term "shared" means that the same physical channel can be used by multiple users at the same time, or that the channel has a short duration.

[0031] Uplink Control Information (UCI) is a mechanism used in wireless communication systems to transmit control information on the uplink. UCI mainly carries various information related to the current state of the terminal device, which can be used for resource scheduling and error control of network devices.

[0032] The current 3GPP NR protocol defines multiplexing rules for three types of uplink control information: Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK), Channel State Information Report (CSI report), and Scheduling Request (SR) to achieve data transmission. However, if new types of uplink control information are introduced during data transmission, the current uplink control information multiplexing rules cannot resolve the multiplexing conflict between the current UCI signaling and the new UCI signaling, making data transmission difficult.

[0033] Based on this, embodiments of this application provide a data transmission method in which a terminal device acquires uplink control information to be transmitted. The uplink control information includes at least one of Hybrid Automatic Repeat Request Acknowledgment (HARQ), Channel State Information Report (CSIS), and Scheduling Request (SSS), as well as a first channel indication. The first channel indication is used to instruct the terminal device to initiate and / or perform an event-driven beam report transmission process. The priority of the first channel indication is lower than the priority of a positive Link Recovery Request (LRR) in the SR. The priority order between the first channel indication and other SRs with non-positive LRRs is determined by the earlier start time slot of the first channel indication and other SRs, or by the first channel indication having a lower priority than other SRs, a positive LRR having a lower priority than HARQ-ACK, and other SRs having a higher priority than CSI report. Based on this, the terminal device can determine at least one uplink control information and uplink physical control channel resources for carrying at least one uplink control information from the uplink control information to be transmitted, according to the multiplexing rules corresponding to the uplink control information to be transmitted. The multiplexing rules include multiplexing rules between at least one of HARQ-ACK, CSI report, and SR and the first channel indication. Uplink control information is transmitted based on uplink physical control channel resources.

[0034] The first channel indication is a new UCI signaling, occupying a bit width of 1 bit, used for the UE-initiated / event-driven beam reporting procedure in New Radio (NR) version 19.

[0035] In this embodiment, the multiplexing rules for uplink control information are updated. In the case of newly added types of uplink control information, uplink control information can be transmitted based on the updated multiplexing rules.

[0036] like Figure 1 As shown in the figure, this is a schematic diagram of an application scenario for data transmission provided by an embodiment of this application. The method provided by this embodiment enables data transmission between at least one network device and at least one terminal device.

[0037] The network device in this embodiment is a network-side entity used for transmitting or receiving signals. It can exchange received air frames with Internet Protocol (IP) packets, acting as a router between the terminal device and the rest of the access network, which may include IP networks, etc. The network device can also coordinate the management of air interface attributes. For example, the network device can be an evolved Node B (eNB or e-NodeB) in LTE, a new radio controller (NR controller), a gNodeB (gNB) in a 5G system, a centralized unit, a new radio base station, a remote radio module, a micro base station, a relay, a distributed unit, a transmission reception point (TRP), a transmission point (TP), or any other wireless access device.

[0038] A terminal device is an entity on the user side used to receive or transmit signals. A terminal device can be a device that provides voice and / or data connectivity to the user, such as a handheld device or in-vehicle device with wireless connectivity. A terminal device can also be other processing devices connected to a wireless modem.

[0039] Terminal equipment can communicate with the radio access network (RAN). Terminal equipment can also be referred to as a wireless terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user equipment (UE), etc.

[0040] In this embodiment, the terminal device can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. The terminal device can also be a personal communication service (PCS) phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), etc. Common terminal devices include, but are not limited to, mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices such as smartwatches, smart bracelets, pedometers, vehicle communication devices, and IoT devices.

[0041] In this embodiment of the application, in the case of Mode B, the terminal device sends a first channel indication to notify the network device to send a beam report on the pre-configured resources, and then sends the beam report on the second uplink channel using the pre-configured resources.

[0042] After the terminal device sends the X symbol of the last symbol of the first channel indication, it sends a beam report at the first available transmission opportunity, where X is a positive integer greater than or equal to 0.

[0043] In some embodiments, the first channel indication is applicable to Mode A. First, the terminal device sends the first channel indication to the network device to request resources for transmitting beam reports on the second uplink channel. Then, the terminal device detects downlink control information (DCI) format indicating the resources of the second uplink channel for carrying beam reports. Finally, the terminal device transmits beam reports on the second uplink channel.

[0044] In some embodiments, the first channel indication applies to both Mode-B and Mode-A.

[0045] In some embodiments, the first channel may be in the form of a proprietary SR.

[0046] In some embodiments, a first channel indication is associated with one or more pre-configured resources for transmitting a second channel beam report.

[0047] In this embodiment, the terminal device acquires uplink control information to be transmitted. The uplink control information to be transmitted includes at least one of Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK), Channel State Information Report (CSS), and Scheduling Request (SSR), as well as a first channel indication. The first channel indication is used to instruct the terminal device to initiate and / or event-driven beam report transmission procedures. The priority of the first channel indication is lower than the priority of a positive Link Recovery Request (LRR) in the SR. The priority order between the first channel indication and other SRs with non-positive LRRs is determined by the earlier start time slot of the first channel indication and other SRs, or by the first channel indication having a lower priority than other SRs, a positive LRR having a lower priority than a HARQ-ACK, and other SRs having a higher priority than a CSI report.

[0048] Based on this, the terminal device can determine at least one uplink control information and uplink physical control channel resources for carrying at least one uplink control information from the uplink control information to be transmitted, according to the multiplexing rules corresponding to the uplink control information to be transmitted; the multiplexing rules include the multiplexing rules between at least one of HARQ-ACK, CSI report, and SR and the first channel indication. Uplink control information is then transmitted based on the uplink physical control channel resources.

[0049] The following is combined Figure 2 The data transmission method provided in the embodiments of this application will be described below. Figure 2 A flowchart illustrating a data transmission method provided in an embodiment of this application.

[0050] S101. Obtain the uplink control information to be transmitted.

[0051] In this embodiment of the application, the uplink control information to be transmitted may include at least one of Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK), Channel State Information Report (CSI report), and Scheduling Request (SR), as well as a first channel indication (the first channel indication of the beam report transmission process initiated by the terminal device and / or event-driven, hereinafter referred to as UEI).

[0052] The first channel indication is used as the first step in a beam report transmission process initiated and / or event-driven by the terminal device. The UE uses the first channel indication to request resources from the network device for sending beam reports, or to notify the network device of pre-configured resources for sending beam reports. This is a new type of uplink control information. The priority of this first channel indication is lower than the priority of the positive Link Recovery Request (LRR) in the SR, but higher than the priority of the CSI report.

[0053] Based on the status of SR, SRs can be divided into positive SRs and negative SRs. A positive status means that the SR resource is sent when the UE has an SR to send; a negative status means that the SR resource is sent when the UE does not have an SR to send.

[0054] According to the status of UEI, UEI can be divided into positive UEI and negative UEI. A positive status means that the UEI resource is being sent and the UE has UEI to send; a negative status means that the UEI resource is being sent and the UE does not have UEI to send.

[0055] It is understood that the priorities of different types of uplink control information in the embodiments of this application may be predefined or configured by network devices.

[0056] In one possible implementation, the priority order of uplink control information is as follows: HARQ-ACK has a higher priority than SR, SR has a higher priority than UEI, and UEI has a higher priority than CSI report.

[0057] In one possible implementation, the priority order of uplink control information is as follows: HARQ-ACK has a higher priority than SR-LRR, SR-LRR has a higher priority than UEI, UEI has a higher priority than or equal to the priority of other SRs that are not LRRs, and other SRs that are not LRRs have a higher priority than CSI report.

[0058] In one possible implementation, the first channel indication is a proprietary SR, which can be represented as SR-UEI. The priority order of uplink control information is as follows: HARQ-ACK has a higher priority than SR-LRR, SR-LRR has a higher priority than SR-UEI, SR-UEI has a higher priority than other non-LRR SRs, and other non-LRR SRs have a higher priority than CSI report.

[0059] Alternatively, HARQ-ACK has a higher priority than SR-LRR, SR-LRR has a higher priority than other SRs that are not LRR within the SR category, and other SRs that are not LRR within the SR category have a higher priority than CSI report. Among these, the other SRs that are not LRR within the SR category contain this SR-UEI.

[0060] S102. Based on the multiplexing rules corresponding to the uplink control information to be transmitted, determine at least one uplink control information and uplink physical control channel resources for carrying the at least one uplink control information from the uplink control information to be transmitted.

[0061] In this embodiment of the application, uplink physical control channel resources refer to PUCCH resources configured on the network side, which can be carried on the PUCCH channel or the PUSCH channel.

[0062] The multiplexing rules include multiplexing rules between at least one of HARQ-ACK, Channel State Information Report (CSI report), and Scheduling Request (SR) and the first channel indication. For example, multiplexing rules between UEI and SR; multiplexing rules between UEI and HARQ-ACK; multiplexing rules between UEI, HARQ-ACK, and SR; multiplexing rules between UEI and CSI report; multiplexing rules between UEI, CSI report, and SR; multiplexing rules between UEI, HARQ-ACK, and CSI report; and multiplexing rules between UEI, HARQ-ACK, CSI report, and SR.

[0063] S103. Based on the uplink physical control channel resources, transmit the uplink control information.

[0064] In this embodiment, the priority of different types of uplink control information can be determined based on the uplink request from the terminal device. Based on the priority of different types of uplink control information, corresponding multiplexing rules can be determined. Then, based on the corresponding multiplexing rules, at least one type of uplink control information and uplink physical control channel resources for carrying the at least one type of uplink control information are determined from the uplink control information to be transmitted. Finally, the uplink control information can be transmitted using the uplink physical control channel resources carrying the at least one type of uplink control information.

[0065] In one possible implementation, the uplink control information to be transmitted is UEI and SR, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between UEI and SR.

[0066] The reuse rules between UEI and SR are described below.

[0067] When the uplink physical channel format of UEI is 0, that is, when UEI adopts PUCCH format 0, UEI information can be mapped to PUCCH format 0 through different sequence cyclic shifts.

[0068] For example, the mapping sequence of UEI values ​​on PUCCH format 0 is shown in Table 1 below:

[0069] Table 1

[0070] UEI value 0 1 Circular shift of sequence mcs=1 mcs=7

[0071] The mapping sequence of UEI values ​​and positive SRs on PUCCH format 0 is shown in Table 2 below:

[0072] Table 2

[0073] UEI value 0 1 Circular shift of sequence mcs=4 mcs=10

[0074] It is understood that the value of the sequence cyclic shift is not specifically limited in the embodiments of this application, and its value can be any permutation and combination of 0-11. The value of mcs mentioned above is only an example.

[0075] When the uplink physical channel format of UEI is 1 and the uplink physical channel format of SR is 0, that is, when UEI adopts PUCCH format 1 and SR adopts PUCCH format 0, the terminal device determines whether the SR is a positive LRR or a positive SR other than a positive LRR.

[0076] If the SR is determined to be a positive LRR, the positive LRR can be determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying the positive LRR is the UEI PUCCH format 1, so that the positive LRR can be sent based on the UEI PUCCH format 1 in the future.

[0077] In the case where the SR is determined to be a positive SR other than a positive LRR, the uplink control information with higher priority can be determined from the uplink control information to be transmitted according to the priority of UEI and SR, and the uplink physical control channel resource for carrying the high-priority uplink control information is the PUCCH format 1 of UEI.

[0078] For example, if the priority of UEI is higher than the priority of SR, UEI is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying UEI is PUCCH format 1 for UEI, so that UEI can be sent based on PUCCH format 1 of UEI and SR can be discarded; if the priority of SR is higher than the priority of UEI, SR is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying SR is PUCCH format 1 for UEI, so that SR can be sent based on PUCCH format 1 of UEI and UEI can be discarded.

[0079] In one possible implementation, the PUCCH format 1 design can be enhanced to support mcs values ​​not equal to 0. Based on this, if the SR is a positive proprietary SR, and mcs takes a non-zero value (e.g., mcs equals 2), the terminal device can simultaneously send UEI and SR-UEI; otherwise, it only sends UEI. The enhanced PUCCH format 1 design refers to the case where mcs can be non-zero.

[0080] When the uplink physical channel format of UEI is 1 and the uplink physical channel format of SR is 1, that is, when UEI adopts PUCCH format 1 and SR adopts PUCCH format 1, the terminal device determines whether the SR is a positive SR.

[0081] If the SR is determined to be a positive SR, the UEI is determined from the uplink control information to be transmitted, and the PUCCH format 1 of the SR with positive uplink physical control channel resources is determined, so that the UEI can be sent based on the PUCCH format 1 of the positive SR in the future.

[0082] If the SR is determined to be negative, the UEI is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying the UEI is PUCCH format 1 of the UEI, so that the UEI can be sent based on the PUCCH format 1 of the UEI in the future.

[0083] In one possible implementation, when both a positive UEI and a positive SR are PUCCH 0 or PUCCH 1, the terminal device determines the uplink control information based on the start timeslots of the UEI and SR. For example, if the start timeslot of the UEI is earlier than the start timeslot of the SR, the UEI is determined to be transmitted; if the start timeslot of the SR is earlier than the start timeslot of the UEI, the SR is determined to be transmitted; if the start timeslots of the UEI and SR are the same, either the UEI or the SR can be arbitrarily determined for transmission.

[0084] In one possible implementation, if the uplink control information to be transmitted is a positive LRR other than a SR and a first channel indication, then the terminal device determines the uplink control information with a positive state and the earliest start time slot from the other SRs other than the positive LRR and the first channel indication.

[0085] In one possible implementation, when the UEI uses at least one of the uplink physical control channel resources of PUCCH 2, PUCCH 3 and PUCCH 4, data transmission can be performed by separately encoding or combining the encoding of SR and UEI.

[0086] When SR and UEI are encoded separately, SR can be sent before or after UEI, where UEI occupies... Bit represents, where, As an up-rounding symbol, UEIs are sorted in ascending order of their signaling identifier (ID) values.

[0087] When SR and UEI are combined and encoded, if UEI is configured with K1 resources and SR is configured with K2 resources, then the combined encoded SR and UEI will occupy... The bits represent the number of UEIs in a time slot and the number of SRs in a time slot.

[0088] In one example, the resources of the SR come first, and the SRs are arranged in ascending order of their scheduling request identifier (SchedulingRequestId) values. The resources of the UEI come last, and the UEIs are arranged in ascending order of their signaling identifier (ID) values.

[0089] In one possible implementation, the uplink control information to be transmitted is UEI and HARQ-ACK, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between UEI and HARQ-ACK.

[0090] The reuse rules between UEI and HARQ-ACK are described below.

[0091] When the uplink physical channel format of HARQ-ACK is 0, that is, when HARQ-ACK adopts PUCCH format 0, the mapping sequence of 1 bit of HARQ-ACK information and positive UEI on PUCCH format 0 is shown in Table 3.

[0092] Table 3

[0093] HARQ-ACK value 0 1 Circular shift of sequence mcs=1 mcs=7

[0094] The mapping sequence of 2-bit HARQ-ACK information and positive UEI on PUCCH format 0 is shown in Table 4.

[0095] Table 4

[0096]

[0097] When the uplink physical channel format of HARQ-ACK is 1 (i.e., HARQ-ACK uses PUCCH format 1), the terminal device determines whether the uplink physical channel format corresponding to UEI is 1 and whether UEI is a positive UEI. If it is determined that the uplink physical channel format corresponding to UEI is 1 and UEI is a positive UEI, then it determines to send HARQ-ACK, and the uplink physical control channel resource carrying HARQ-ACK is the line physical control channel resource of UEI.

[0098] When the uplink physical channel format of HARQ-ACK is at least one of 2, 3, or 4, that is, when HARQ-ACK uses at least one of PUCCH format 2, 3, or 4, the total number of bits of uplink control signaling to be transmitted is O. UCI =O ACK +O UEI The HARQ-ACK bits come first, followed by the UEI bits. The total number of bits of the uplink control signaling to be sent is compared with the upper limit of the number of bits supported by the uplink physical control channel resources.

[0099] For example, if O ACK +O UEI Greater than the upper limit of the number of bits supported by the uplink physical control channel resources, O ACK If the number of bits supported by the uplink physical control channel resources is less than or equal to the upper limit of the number of bits, then only HARQ-ACK is sent and UEI is discarded.

[0100] Among them, O ACK Indicates the number of bits to be sent in the HARQ-ACK, O UEI This indicates the number of bits of the UEI to be sent. UEIs are arranged in ascending order of their signaling identifier (ID) values. Since HARQ-ACK has a higher priority than UEI, the information bits of HARQ-ACK are placed before the information bits of UEI.

[0101] In one possible implementation, the uplink control information to be transmitted is UEI, HARQ-ACK, and SR. The multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between UEI, HARQ-ACK, and SR.

[0102] The reuse rules between UEI, HARQ-ACK, and SR are described below.

[0103] When the uplink physical channel format of HARQ-ACK is 0, that is, when HARQ-ACK adopts PUCCH format 0, the mapping sequence of 1 bit of HARQ-ACK information, positive SR and positive UEI on PUCCH format 0 is shown in Table 5.

[0104] Table 5

[0105]

[0106]

[0107] When 2-bit HARQ-ACK information, positive SR, and positive UEI coexist, the terminal device first performs conflict resolution on the positive SR and positive UEI, and determines an uplink control information from the positive SR and positive UEI to be loaded onto the 2-bit HARQ-ACK.

[0108] In one example, the terminal device can compare the start timeslots of a positive SR and a positive UEI, load the uplink control information with the earlier start timeslot onto the 2-bit HARQ-ACK, and discard the other uplink control information; if the start timeslots of the two are the same, it can select either one or a predefined uplink control information (such as selecting UEI in this case) to load onto the 2-bit HARQ-ACK, and discard the other uplink control information.

[0109] In another example, the terminal device can compare the priorities of a positive SR and a positive UEI, and load the uplink control information with the higher priority onto the 2-bit HARQ-ACK, while discarding the other uplink control information. For example, when the positive SR is a positive SR-LRR, the positive SR-LRR has a higher priority than the positive UEI, so the positive SR-LRR is loaded onto the 2-bit HARQ-ACK, and the positive UEI is discarded; if the priorities of the positive SR and the positive UEI are the same, the terminal device can compare the start timeslots of the positive SR and the positive UEI, and load the uplink control information with the earlier start timeslot onto the 2-bit HARQ-ACK, while discarding the other uplink control information; if the start timeslots are the same, either one can be randomly selected to load onto the 2-bit HARQ-ACK, and the other uplink control information is discarded.

[0110] When the uplink physical channel format of HARQ-ACK is 1 or 0, i.e., when HARQ-ACK uses PUCCH format 1 or 0, the terminal device can perform conflict resolution on positive SR and positive UEI, and determine an uplink control message from the positive SR and positive UEI to be carried onto the 2-bit HARQ-ACK. For ease of subsequent description, the uplink control message determined from the positive SR and positive UEI can be referred to as the first uplink control message.

[0111] If the uplink physical channel format of HARQ-ACK is 0, then it is determined that HARQ-ACK will be sent, and the uplink physical control channel resource carrying HARQ-ACK will be determined as the uplink physical control channel of HARQ-ACK.

[0112] If the uplink physical channel format of HARQ-ACK is 1, then it is determined whether the uplink physical control channel format of the first uplink control information is 1, and whether the first uplink control information is a positive first uplink control information. If it is determined that the uplink physical control channel format of the first uplink control information is 1, and the first uplink control information is a positive first uplink control information, then it is determined to send HARQ-ACK, and the uplink physical control channel resource carrying HARQ-ACK is determined to be the uplink physical control channel of the first uplink control information; otherwise, it is determined to send acknowledgment / negative acknowledgment information (ACK / NACK), and the uplink physical control channel resource carrying ACK / NACK is determined to be the uplink physical control channel of HARQ-ACK.

[0113] In one possible implementation, the uplink physical channel format of HARQ-ACK is 1, that is, when HARQ-ACK adopts PUCCH format 1, the terminal device determines the uplink physical channel format of SR and UEI. Based on the uplink physical channel format of SR and UEI, at least one uplink control information and uplink physical control channel resources for carrying the at least one uplink control information are determined from the uplink control information to be transmitted.

[0114] For example, if it is determined that the uplink physical channel format of both SR and UEI is 0, it can be determined that only HARQ-ACK is sent and SR and UEI are discarded.

[0115] The terminal equipment determines that in SR and UEI, one uplink control information has an uplink physical channel format of 1, and the other uplink control information has an uplink physical channel format of 0. In this case, if the uplink control information with an uplink physical channel format of 1 is positive, it determines to send HARQ-ACK, and determines that the uplink physical control channel resource carrying HARQ-ACK is the uplink physical control channel of the positive uplink control information with an uplink physical channel format of 1; if the uplink control information with an uplink physical channel format of 1 is negative, it determines to send ACK / NACK, and determines that the uplink physical control channel resource carrying ACK / NACK is the uplink physical control channel of HARQ-ACK.

[0116] If the terminal equipment determines that the uplink physical channel format of both SR and UEI is 1, then when SR is positive and UEI is negative, it determines to send HARQ-ACK and determines that the uplink physical control channel resource carrying HARQ-ACK is the uplink physical control channel of the positive SR; when SR is negative and UEI is positive, it determines to send HARQ-ACK and determines that the uplink physical control channel resource carrying HARQ-ACK is the uplink physical control channel of the positive UEI; when SR is positive and UEI is positive, it determines the starting timeslot of SR and UEI, if SR's... If the starting timeslot of SR is earlier than the starting timeslot of UEI, then HARQ-ACK is determined to be sent, and the uplink physical control channel resource carrying HARQ-ACK is determined to be the uplink physical control channel of SR. If the starting timeslot of SR is later than the starting timeslot of UEI, then HARQ-ACK is determined to be sent, and the uplink physical control channel resource carrying HARQ-ACK is determined to be the uplink physical control channel of UEI. If the starting timeslot of SR is the same as the starting timeslot of UEI, then HARQ-ACK is determined to be sent, and the uplink physical control channel resource carrying HARQ-ACK is determined to be the uplink physical control channel of either SR or UEI.

[0117] In one possible implementation, the uplink physical channel format of HARQ-ACK is at least one of 2, 3, and 4. That is, when HARQ-ACK adopts at least one of PUCCH format 2, 3, and 4, it can be determined that HARQ-ACK, SR, and UEI are sent simultaneously, and the uplink physical control channel resource carrying HARQ-ACK, SR, and UEI is determined to be the uplink physical control channel of HARQ-ACK.

[0118] In this case, if HARQ-ACK, SR, and UEI are encoded separately, the total number of bits of the uplink control signaling to be transmitted is O. UCI =O ACK +O SR +OUEI O SR This indicates the number of bits in the SR to be sent.

[0119] If UEI is configured with K1 resources and SR is configured with K2 resources, then the number of bits required to transmit UEI is: UEIs are sorted in ascending order of their signaling ID values. The number of bits required to transmit the SR is... The SRs are sorted in ascending order of the values ​​of the scheduling request identifiers. In this case,

[0120] When SR and UEI are combined and encoded, if UEI is configured with K1 resources and SR is configured with K2 resources, then the combined encoded SR and UEI will occupy... Bits, where K1 represents the number of UEIs occurring in a time slot, and K2 represents the number of SRs occurring in a time slot.

[0121] In one example, the resources of the SR come first, and the SRs are arranged in ascending order of the value of the scheduling request identifier. The resources of the UEI come last, and the UEIs are arranged in ascending order of the value of their signaling ID.

[0122] In one possible implementation, the uplink control information to be transmitted is UEI and CSI report, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between UEI and CSI.

[0123] The reuse rules between UEI and CSI reports are described below.

[0124] If the uplink physical channel format of the CSI report is at least one of 2, 3, or 4, then the total number of bits of the uplink control signaling to be transmitted is O. UCI =O UEI +O CSI O CSI Indicates the number of bits required to transmit the CSI report. Before the CSI report, UEIs are sorted in ascending order of their signaling ID values.

[0125] In one possible implementation, the uplink control information to be transmitted is UEI, SR, and CSI report, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule among UEI, SR, and CSI report.

[0126] The following section introduces the reuse rules among UEI, SR, and CSI reports.

[0127] If the uplink physical channel format of the CSI report is one of 2, 3, or 4, then it is determined that UEI, SR, and CSI report are transmitted, and the uplink physical control channel resource carrying UEI, SR, and CSI report is the uplink physical control channel of CSI report.

[0128] In one example, the total number of bits in the uplink control signaling to be sent is O. UCI =O ACK +O SR +O UEI +O CSI Based on the priorities of UEI, SR, and CSI report, and the upper limit of the number of bits supported by the uplink physical control channel resources of the CSI report, the first number of bits of the first channel indication, the second number of bits of the CSI report, and the third number of bits of the SR can be determined from the uplink control information to be transmitted.

[0129] When UEI, SR, and CSI report are encoded separately, the uplink physical control channel resources based on the CSI report can transmit a first number of bits of first channel indication, a second number of bits of CSI report, and a third number of bits of SR.

[0130] Among them, the first number of bits of the UEI to be sent is O UEI It can be represented as The third bit of the SR to be sent can be represented as: SRs are sorted in ascending order of scheduling request identifier value, followed by UEI resources, and UEIs are sorted in ascending order of their signaling ID value.

[0131] If the CSI report, SR, and UEI are jointly encoded, the number of bits required to transmit the CSI report, SR, and UEI is the sum of the number of bits after jointly encoding the SR and UEI and the number of bits required for the CSI report. Specifically, the first channel indication (first bit count) and the third SR (first channel indication and SR) are jointly encoded to obtain the fourth coded bit count. or

[0132] In one possible implementation, the uplink control information to be transmitted is UEI, HARQ-ACK, and CSIreport. The multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule among UEI, HARQ-ACK, and CSI report.

[0133] The reuse rules among UEI, HARQ-ACK, and CSI reports are similar to the existing reuse rules among HARQ-ACK, CSI, and SR, and will not be repeated here.

[0134] In one possible implementation, the uplink control information to be transmitted is UEI, SR, HARQ-ACK, and CSIreport. The multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule among UEI, SR, HARQ-ACK, and CSIreport.

[0135] The following section introduces the reuse rules among UEI, SR, HARQ-ACK, and CSI reports.

[0136] Based on the priority among HARQ-ACK, SR, first channel indication, and CSI report, and the upper limit of the number of bits supported by the uplink physical control channel resources, the fifth bit of HARQ-ACK, the sixth bit of SR, the seventh bit of first channel indication, and the eighth bit of CSI report can be determined from the uplink control information to be transmitted; and they are sequentially carried on the uplink physical control channel resources for transmission.

[0137] Based on the uplink physical control channel resources, the fifth bit of HARQ-ACK, the sixth bit of SR, the seventh bit of the first channel indication, and the eighth bit of CSI report are transmitted.

[0138] For example, when UEI, SR, HARQ-ACK, and CSI report are encoded separately, the number of seventh bits required to transmit UEI can be expressed as follows: UEIs are sorted in ascending order of their signaling ID values.

[0139] When UEI is a proprietary SR, the number of bits required to transmit UEI can be expressed as: or

[0140] In one possible implementation, the uplink control information to be transmitted includes one or more CSI reports, and zero or more HARQ-ACK, SR, and UEI. HARQ-ACK is used to respond to indications for semi-persistent scheduling (SPS) PDSCH reception. If any CSI reports overlap, and the terminal device is configured with a multi-CSI-PUCCH resource list (multi-CSI-PUCCH-ResourceList) with a configured resource count less than or equal to two, PUCCH 2 / 3 / 4 are arranged in ascending order of the number of bits they can carry.

[0141] In this case, if the number of bits of uplink control information that can be transmitted The terminal device uses PUCCH 0; if the number of uplink control information bits that can be transmitted is 0... UCI ≥ and The terminal device uses PUCCH resource j+1 to send HARQ-ACK, SR, UEI and CSI report; otherwise, the terminal device uses PUCCH resource J-1 to select the high-priority CSI report and transmit it together with HARQ-ACK, SR and UEI.

[0142] in, Uplink transmission scheduling bandwidth is represented by the number of resource blocks (RBs). The number of controllable subcarriers for each RB in different PUCCH formats; Q represents the OFDM symbol length corresponding to different PUCCH formats. m is the modulation order; r is the maximum code rate.

[0143] In this embodiment, if multiple CSI reports conflict, it is necessary to determine the priority of each CSI report. This applies to CSI reports used in UE-initiated / event-driven beamreporting beam reporting transmission procedures.

[0144] For ease of description, the CSI report used in the beam report transmission process for UE-initiated / event-driven beamreporting can be referred to as the UEI's CSI report.

[0145] In this embodiment of the application, the priority order of the UEI's CSI reports can be configured and indicated by the network device.

[0146] In some examples, the priority of UEI's CSI report is lower than that of LTM's CSI report, but higher than that of other CSI reports.

[0147] In some examples, the priority of UEI CSI reports is higher than that of LTM CSI reports, and the priority of LTMCSI reports is higher than that of other CSI reports.

[0148] In some examples, the priority of the UEI CSI report in Mode A is lower than the priority of the LTM CSI report, but higher than the priority of the UEI CSI report in Mode B. The priority of the UEI CSI report in Mode B is higher than the priority of other CSI reports.

[0149] In some examples, the priority of the UEI CSI report in Mode B is lower than the priority of the LTM CSI report, but higher than the priority of the UEI CSI report in Mode A. The priority of the UEI CSI report in Mode A is higher than the priority of other CSI reports.

[0150] In some examples, the priority of the UEI CSI report of Mode B is higher than the priority of the UEI CSI report of Mode A, the priority of the UEI CSI report of Mode A is higher than the priority of the LTM CSI report, and the priority of the LTMCSI report is higher than the priority of other CSI reports.

[0151] In some examples, the priority of the UEI CSI report in Mode A is higher than that of the UEI CSI report in Mode B, the priority of the UEI CSI report in Mode B is higher than that of the LTM CSI report, and the priority of the LTMCSI report is higher than that of other CSI reports.

[0152] In this embodiment of the application, the priority value of the CSI report can be calculated according to the following formula (1).

[0153] Pri iCSI (y, k, c, s) = 2N cells M s y+N cells Ms k+M s k+M s c+s (1)

[0154] Wherein, if y = 0, it means that PUSCH carries non-periodic CSI reports; if y = 1, it means that PUSCH carries semi-persistent CSI reports; if y = 2, it means that PUCCH carries semi-persistent CSI reports; if y = 3, it means that PUCCH carries periodic CSI reports.

[0155] If k = 0, it means that CSI reports carry L1-RSRP or L1-SINR; if k = 1, it means that CSI reports do not carry L1-RSRP or L1-SINR.

[0156] c is the serving cell index, N cells This is the value of the higher-level parameter, maximum number of serving cells (maxNrofServingCells); s is the report configuration identifier (reportConfigID), M s It is the value of the maximum number of channel state information (CSI) report configurations (maxNrofCSI-ReportConfigurations) for higher-layer parameters.

[0157] In one example, the value of y is related to the priority of the event type. For example, event 1 corresponds to y=0, event 2 corresponds to y=1, and event 7 corresponds to y=2.

[0158] In one example, the value of y depends on the event reporting method. For instance, after an event occurs, the terminal device may only report the CSI report once, similar to existing non-periodic CSI reports; or the terminal device may continuously report the CSI report after an event occurs, similar to existing semi-persistent CSI reports.

[0159] In one example, the value of y is related to event reporting. For example, using method 1, DCI triggers an aperiodic CSI report; using method 2, DCI triggers a semi-persistent CSI report.

[0160] M s This indicates the maximum number of event-triggered CSI reports that can be configured within a Component Carrier (CC).

[0161] For example, when the network device is only configured with Mode A, M sThis indicates the maximum number of event-triggered CSI reports that can be configured within a CC for Mode A.

[0162] When the network device is only configured with Mode B, M s This indicates the maximum number of event-triggered CSI reports that can be configured within a single CC for Mode B.

[0163] In one example, the value of y is related to the type of CSI channel carried. For example, the priority of Dynamically Granted Physical Uplink Shared Channel (DG-PUSCH) is higher than that of Configuration Granted Physical Uplink Shared Channel (CG-PUSCH), or Mode A has a higher priority than Mode B.

[0164] It should be noted that in mode B, this CG-PUSCH is the CG 1PUSCH used to carry the CSI report. In some embodiments, the CG 1PUSCH carrying the CSI report can also be used to send other uplink control signaling and / or uplink data.

[0165] In one possible implementation, when the candidate PUSCHs include first PUSCHs scheduled by DCI and second PUSCHs configured with configuration authorization (CGConfig) or semi-static configuration (SP) on the Physical Uplink Shared Channel (PUSCH), UCI multiplexes one PUSCH from the first PUSCHs based on multiplexing timing constraints. The priority of the multiplexed PUSCH type is that the priority of DG PUSCH is greater than that of SP PUSCH, and the priority of SP PUSCH is greater than that of CG 1PUSCH.

[0166] In this embodiment of the application, there may be overlap between non-repeating PUCCH and PUSCH, as shown in Table 6. Table 6 lists the reuse rules when there is overlap between non-repeating PUCCH and PUSCH.

[0167] Table 6

[0168]

[0169]

[0170] As shown in Table 6, in this embodiment of the application, when the uplink control information to be transmitted includes a positive first channel indication, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources that do not carry uplink shared channel data, the physical uplink shared channel resources are discarded, and the uplink control information is transmitted based on the uplink physical control channel resources.

[0171] When the uplink control information to be transmitted includes a positive first channel indication, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources carrying uplink shared channel data, the physical uplink shared channel resources of the uplink control information to be transmitted are discarded, and the physical uplink shared channel resources are transmitted.

[0172] When the uplink control information to be transmitted includes a positive first channel indication and a positive SR, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources that do not carry uplink shared channel data, the physical uplink shared channel resources are discarded and the uplink physical control channel resources of the uplink control information are transmitted.

[0173] When the uplink control information to be transmitted includes a positive first channel indication and a positive SR, and the physical uplink shared channel resources of the uplink control information to be transmitted overlap with the physical uplink shared channel resources carrying uplink shared channel data, the uplink physical control channel resources of the uplink control information are discarded, and the physical uplink shared channel resources are transmitted.

[0174] In summary, the uplink control information reuse rules have been updated in this application embodiment. In the case of newly added types of uplink control information, uplink control information can be transmitted based on the updated reuse rules.
