Description

Data transmission method and related device

[0001] The present application claims priority to the Chinese patent application No. 202411338654.5, filed on September 24, 2024, and entitled "A data transmission method and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronics, and in particular to a data transmission method and related device. BACKGROUND

[0003] Uplink control information (UCI) multiplexing refers to a process of combining uplink control information from multiple uplink physical control channels into one uplink physical control channel for transmission when the uplink physical control channels (PUCCH) that transmit the uplink control information overlap in the time domain in the 3GPP NR protocol.

[0004] The current 3GPP NR protocol defines multiplexing rules among three types of uplink control information, i.e., hybrid automatic repeat request acknowledgement (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 in the process of data transmission, the current uplink control information multiplexing rules cannot be compatible with the addition of a new type of uplink control signaling, thereby making the user equipment (UE) unable to complete the processing and transmission of uplink control signaling.

[0027] The terms "first", "second", and "third" and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the descriptive terms "first", "second", and "third" are to be interpreted, by those skilled in the art, as a flexible

[0028] In the present application, the words "example" and "exemplary" are used to mean serving as an example, instance, or illustration. Any implementation or design solution described as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations or design solutions. Rather, the use of the terms "example" and "exemplary" is intended to present concepts in a concrete manner.

[0029] The technical concepts in the embodiments of the present application are introduced for the convenience of understanding.

[0030] The Physical Uplink Control Channel (PUCCH) is a physical channel used for transmitting UCI, which supports multiple transmission formats (formats), and different formats determine different bit numbers and occupied Orthogonal Frequency Division Multiplexing (OFDM) symbol lengths.

[0031] The Physical Uplink Shared Channel (PUSCH) is used for carrying uplink data transmission from a terminal device to a network device, i.e., when the terminal device has data to send (such as voice, video or other data), the data can be sent to the network device through the PUSCH. The so-called shared means that the same physical channel can be used by multiple users at the same time, or the channel has a relatively short duration.

[0032] The Uplink Control Information (UCI) is a mechanism used for transmitting control information on the uplink in a wireless communication system. The UCI mainly carries various information related to the current state of the terminal device, which can be used for resource scheduling, error control, etc.

[0033] In the current 3GPP NR protocol, multiplexing rules among three uplink control information (UCI) of hybrid automatic repeat request acknowledgement (HARQ-ACK), channel state information report (CSI report) and scheduling request (SR) are defined to realize data transmission. However, if a new type of uplink control information is introduced in the process of data transmission, the multiplexing conflict problem between the current UCI signaling and the new UCI signaling cannot be solved based on the current uplink control information multiplexing rule, and it is difficult to perform data transmission.

[0034] Based on this, an embodiment of the present application provides a data transmission method. A terminal device acquires to-be-transmitted uplink control information, wherein the to-be-transmitted uplink control information includes at least one of hybrid automatic repeat request acknowledgement, channel state information report and scheduling request, and a first channel indication. The first channel indication is used to indicate that the terminal device initiates and / or event-driven beam report transmission procedure. The priority of the first channel indication is lower than that of a positive link recovery request (LRR) in the SR. The priority order between the first channel indication and other SRs of a non-positive LRR in the SR is determined by the earlier one of the starting time slots of the first channel indication and the other SRs, or the priority of the first channel indication is lower than that of the other SRs. The priority of the positive LRR is lower than that of the HARQ-ACK. The priority of the other SRs is higher than that of the CSI report. On this basis, the terminal device can determine at least one uplink control information and an uplink physical control channel resource for carrying the at least one uplink control information from the to-be-transmitted uplink control information according to the multiplexing rule corresponding to the to-be-transmitted uplink control information. The multiplexing rule includes the multiplexing rule between at least one of HARQ-ACK, CSI report and SR and the first channel indication. Based on the uplink physical control channel resource, the uplink control information is transmitted.

[0035] The first channel indication is a new UCI signaling, occupies a bit width of 1 bit, and is used for an on beam report transmission procedure for UE-initiated / event-driven beam reporting in a new radio (NR) 19th version.

[0036] In the embodiment of the present application, the multiplexing rule of the uplink control information is updated. In the case where a new type of uplink control information exists, the uplink control information can be transmitted based on the updated multiplexing rule.

[0037] As shown in FIG.1, which is a schematic diagram of an application scenario of data transmission provided by the embodiments of the present application. The method provided by the embodiments of the present application implements data transmission between at least one network device and at least one terminal device.

[0038] The network device in the embodiments of the present application is an entity for transmitting or receiving signals on the network side, which can be used to exchange received air frames and internet protocol (IP) packets with each other as a router between a terminal device and the rest of an access network, which can include an IP network and the like. The network device can also coordinate the management of the properties of the air interface. For example, the network device can be an evolutional Node B (eNB or e-NodeB) in LTE, and can also be a new radio controller (NR controller), a gNodeB (gNB) in a 5G system, a centralized unit, a new radio base station, a radio frequency remote 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, and the like.

[0039] The terminal device is an entity for receiving or transmitting signals on the user side. The terminal device can be a device that provides voice and / or data connectivity to a user, such as a handheld device having wireless connection function, a vehicle-mounted device, and the like. The terminal device can also be other processing devices connected to a wireless modem.

[0040] The terminal device can communicate with a radio access network (RAN). The terminal device can also be referred to as a wireless terminal, a subscriber unit, a subscriber station, a mobile, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE), and the like.

[0041] In the embodiments of the present application, the terminal device can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal, for example, can be a portable, pocket-sized, handheld, built-in computer or vehicle-mounted mobile device, which exchanges voice and / or data with a wireless access network. The terminal device can also be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and the like. Common terminal devices include, but are not limited to, mobile phones, tablets, notebook computers, palmtop computers, mobile internet devices (MIDs), wearable devices such as smart watches, smart bands, pedometers, vehicle-mounted communication devices, Internet of Things devices, and the like.

[0042] In the embodiments of the present application, in the case of Mode-B, the terminal device sends the first channel indication to inform the network device to send the beam report on the preconfigured resource, and then sends the beam report on the second uplink channel using the preconfigured resource.

[0043] The terminal device sends the first channel indication X symbols after the last symbol, and sends the beam report in the first available transmission opportunity, where X is a positive integer greater than or equal to 0.

[0044] In some embodiments, the first channel indication is applicable to Mode-A, the terminal device first sends the first channel indication to request resources for sending the beam report on the second uplink channel from the network device, then the terminal device detects a downlink control information (DCI) format to indicate resources of the second uplink channel for carrying the beam report, and finally the terminal device sends the beam report on the second uplink channel.

[0045] In some embodiments, the first channel indication is applicable to both Mode-B and Mode-A.

[0046] In some embodiments, the first channel can be in the form of a dedicated SR.

[0047] In some embodiments, the first channel indication is associated with one or more preconfigured resources for sending the second channel beam report.

[0048] In the embodiment of the present application, the terminal device acquires the uplink control information to be transmitted. The uplink control information to be transmitted includes at least one of a hybrid automatic repeat request acknowledgement, a channel state information report, and a scheduling request, and a first channel indication. The first channel indication is used to indicate that the terminal device initiates and / or event-driven beam report transmission process. The priority of the first channel indication is lower than that of a positive link recovery request LRR in the SR. The priority order between the first channel indication and other SRs of non-positive LRR in the SR is determined by the earlier one of the starting time slots of the first channel indication and the other SRs, or the priority of the first channel indication is lower than that of the other SRs. The priority of the positive LRR is lower than that of the HARQ-ACK. The priority of the other SRs is higher than that of the CSI report.

[0049] On this basis, the terminal device can determine at least one uplink control information and an uplink physical control channel resource for carrying the at least one uplink control information from the uplink control information to be transmitted according to the multiplexing rule corresponding to the uplink control information to be transmitted. The multiplexing rule includes the multiplexing rule between at least one of HARQ-ACK, CSI report, and SR and the first channel indication. The uplink control information is transmitted based on the uplink physical control channel resource.

[0050] The data transmission method provided in the embodiment of the present application will be described below in conjunction with FIG. 2. FIG. 2 is a flowchart of a data transmission method provided in the embodiment of the present application.

[0051] S101, acquiring uplink control information to be transmitted.

[0052] In the embodiment of the present application, the uplink control information to be transmitted can include at least one of a hybrid automatic repeat request acknowledgement (HARQ-ACK), a channel state information report (CSI report), and a scheduling request (SR), and a first channel indication (the first channel indication of the terminal device initiating and / or event-driven beam report transmission process, hereinafter referred to as UEI).

[0053] The first channel indication is used for the first step of the terminal device initiating and / or event-driven beam report transmission process. The UE requests a network device for a resource for sending a beam report through the first channel indication, or notifies the network device of a preconfigured resource for sending a beam report. It is a new type of uplink control information. The priority of the first channel indication is lower than that of a positive link recovery request LRR in the SR, and higher than that of the CSI report.

[0054] According to the state of the SR, the SR can be divided into a positive SR and a negative SR, wherein the state being positive means that the UE has SR transmission at the transmission occasion of the SR resource, and the state being negative means that the UE has no SR transmission at the transmission occasion of the SR resource.

[0055] According to the state of the UEI, the UEI can be divided into a positive UEI and a negative UEI, wherein the state being positive means that the UE has UEI transmission at the transmission occasion of the UEI resource, and the state being negative means that the UE has no UEI transmission at the transmission occasion of the UEI resource.

[0056] It can be understood that the priorities of different types of uplink control information in the embodiments of the present application can be predefined or configured by a network device.

[0057] In a possible implementation, the priority arrangement order of the uplink control information is that the priority of the HARQ-ACK is higher than the priority of the SR, the priority of the SR is higher than the priority of the UEI, and the priority of the UEI is higher than the priority of the CSI report.

[0058] In a possible implementation, the priority arrangement order of the uplink control information is that the priority of the HARQ-ACK is higher than the priority of the SR-LRR, the priority of the SR-LRR is higher than the priority of the UEI, the priority of the UEI is higher than or equal to the priority of other SRs in the SR that are not LRRs, the priority of the other SRs in the SR that are not LRRs is higher than the priority of the CSI report.

[0059] In a possible implementation, the first channel indication is a dedicated SR, and in this case, the first channel indication can be denoted as SR-UEI. The priority arrangement order of the uplink control information is that the priority of the HARQ-ACK is higher than the priority of the SR-LRR, the priority of the SR-LRR is higher than the priority of the SR-UEI, the priority of the SR-UEI is higher than the priority of other SRs in the SR that are not LRRs, and the priority of the other SRs in the SR that are not LRRs is higher than the priority of the CSI report.

[0060] Or, the priority of the HARQ-ACK is higher than the priority of the SR-LRR, the priority of the SR-LRR is higher than the priority of other SRs in the SR that are not LRRs, and the priority of the other SRs in the SR that are not LRRs is higher than the priority of the CSI report. The other SRs in the SR that are not LRRs include the SR-UEI.

[0061] S102, determining at least one uplink control information and an uplink physical control channel resource for carrying the at least one uplink control information from the to-be-transmitted uplink control information according to a multiplexing rule corresponding to the to-be-transmitted uplink control information.

[0062] In the embodiments of the present application, the uplink physical control channel resource refers to a PUCCH resource configured by the network side, which can be carried on a PUCCH channel or a PUSCH channel.

[0063] The multiplexing rule includes at least one of a multiplexing rule between HARQ-ACK, a channel state information report (CSI report), a scheduling request (SR) and the first channel indication, for example, a multiplexing rule between UEI and SR; a multiplexing rule between UEI and HARQ-ACK; a multiplexing rule between UEI, HARQ-ACK and SR; a multiplexing rule between UEI and CSI report; a multiplexing rule between UEI, CSI report and SR; a multiplexing rule between UEI, HARQ-ACK and CSI report; a multiplexing rule between UEI, HARQ-ACK, CSI report and SR.

[0064] S103, transmitting the uplink control information based on the uplink physical control channel resource.

[0065] In the embodiments of the present application, the priority of different types of uplink control information can be determined based on the uplink request of the terminal device, the corresponding multiplexing rule can be determined based on the priority of different types of uplink control information, and at least one uplink control information and an uplink physical control channel resource for carrying the at least one uplink control information can be determined from the to-be-transmitted uplink control information based on the corresponding multiplexing rule. On this basis, the uplink control information can be transmitted based on the uplink physical control channel resource for carrying the at least one uplink control information.

[0066] In a possible implementation, the to-be-transmitted uplink control information is UEI and SR, and the multiplexing rule corresponding to the to-be-transmitted uplink control information is the multiplexing rule between UEI and SR.

[0067] The multiplexing rule between UEI and SR will be introduced below.

[0068] In the case that 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.

[0069] For example, the mapping sequence of UEI value on PUCCH format 0 is shown in Table 1 as follows:

[0070] Table 1

[0071] It can be understood that the value of the sequence cyclic shift in the embodiment of the present application is not specifically limited, and the value can be various permutations and combinations of 0-11. The value of mcs in the table is only an example.

[0072] The mapping sequence of UEI value and positive SR on PUCCH format 0 is shown in Table 2 as follows:

[0073] Table 2

[0074] In the case that the uplink physical channel format of UEI is 1 and the uplink physical channel format of SR is 0, that is, UEI uses PUCCH format 1 and SR uses PUCCH format 0, the terminal device determines whether the SR is a positive LRR or a positive SR other than the positive LRR.

[0075] In the case that the SR is determined to be a positive LRR, the positive LRR and the uplink physical control channel resource for carrying the positive LRR, which is the PUCCH format 1 of UEI, can be determined from the to-be-transmitted uplink control information, so that the positive LRR can be subsequently transmitted based on the PUCCH format 1 of UEI.

[0076] In the case that the SR is determined to be a positive SR other than the positive LRR, the uplink control information with high priority can be determined from the to-be-transmitted uplink control information 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.

[0077] For example, in the case that the priority of UEI is higher than the priority of SR, UEI is determined from the to-be-transmitted uplink control information, and the uplink physical control channel resource for carrying UEI is the PUCCH format 1 of UEI, so that UEI can be subsequently transmitted based on the PUCCH format 1 of UEI, and SR is discarded; in the case that the priority of SR is higher than the priority of UEI, SR is determined from the to-be-transmitted uplink control information, and the uplink physical control channel resource for carrying SR is the PUCCH format 1 of UEI, so that SR can be subsequently transmitted based on the PUCCH format 1 of UEI, and UEI is discarded.

[0078] In a possible implementation, the PUCCH format 1 can be enhanced to support mcs not equal to 0. On this basis, if the SR is a positive dedicated SR, the mcs takes a non-0 value, such as mcs equal to 2, the terminal device can simultaneously send UEI and SR-UEI; otherwise, only UEI is sent. The enhanced PUCCH format 1 means that mcs can take a value not equal to 0.

[0079] In the case that the uplink physical channel format of UEI is 1 and the uplink physical channel format of SR is 1, that is, UEI adopts PUCCH format 1 and SR adopts PUCCH format 1, the terminal device determines whether the SR is a positive SR.

[0080] In the case that the SR is determined to be a positive SR, the UEI is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying the UEI is the PUCCH format 1 of the positive SR, so that the UEI can be sent based on the PUCCH format 1 of the positive SR subsequently.

[0081] In the case that the SR is determined to be a negative SR, the UEI is determined from the uplink control information to be transmitted, and the uplink physical control channel resource for carrying the UEI is the PUCCH format 1 of the UEI, so that the UEI can be sent based on the PUCCH format 1 of the UEI subsequently.

[0082] In a possible implementation, in the case that the positive UEI and the positive SR use PUCCH 0 or PUCCH 1, the terminal device determines the uplink control information according to the starting time slot of the UEI and the starting time slot of the SR. For example, in the case that the starting time slot of the UEI is earlier than the starting time slot of the SR, it is determined to send the UEI; in the case that the starting time slot of the SR is earlier than the starting time slot of the UEI, it is determined to send the SR; and in the case that the starting time slots of the UEI and the SR are the same, one of the UEI and the SR can be determined to send arbitrarily.

[0083] In a possible implementation, in the case that the uplink control information to be transmitted is other SRs except the positive LRR and the first channel indication, the terminal device determines the uplink control information with the state being positive and the starting time slot being the earliest from the other SRs except the positive LRR and the first channel indication.

[0084] In a possible implementation, in the case that the UEI uses at least one of the PUCCH 2, PUCCH 3 and PUCCH 4 uplink physical control channel resources, the data transmission can be performed in the form of separate coding or combined coding of the SR and the UEI.

[0085] In the case of separate encoding of the SR and the UEI, the SR can be sent in front of or behind the UEI, wherein the UEI occupies bits, wherein, is a rounding up symbol, and the UEI is arranged in ascending order of the value of its signaling identity (ID).

[0086] In the case of combined encoding of the SR and the UEI, if the UEI is configured with K1 resources and the SR is configured with K2 resources, the combined encoded SR and the UEI occupy bits, wherein K1 represents the number of occurrences of the UEI in one time slot, and K2 represents the number of occurrences of the SR in one time slot.

[0087] In an example, the resources of the SR are in front, and the SR is arranged in ascending order of the value of the scheduling request identity (SchedulingRequestId); the resources of the UEI are behind, and the UEI is arranged in ascending order of the value of its signaling identity (ID).

[0088] In a possible implementation, the uplink control information to be transmitted is the UEI and the HARQ-ACK, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between the UEI and the HARQ-ACK.

[0089] The multiplexing rule between the UEI and the HARQ-ACK is introduced as follows.

[0090] In the case of an uplink physical channel format 0 of the HARQ-ACK, that is, the HARQ-ACK adopts the PUCCH format 0, the mapping sequence of 1bit of the HARQ-ACK information and the positive UEI on the PUCCH format 0 is shown in Table 3.

[0091] Table 3

[0092] The mapping sequence of 2bit of the HARQ-ACK information and the positive UEI on the PUCCH format 0 is shown in Table 4.

[0093] In the case of an uplink physical channel format 1 of the HARQ-ACK, that is, the HARQ-ACK adopts the PUCCH format 1, the terminal device determines whether the uplink physical channel format corresponding to the UEI is 1 and whether the UEI is a positive UEI. In the case of determining that the uplink physical channel format corresponding to the UEI is 1 and the UEI is a positive UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is the uplink physical control channel resource of the UEI.

[0094] Table 4

[0095] In the case that the uplink physical channel format of HARQ-ACK is at least one of format 2, 3 and 4, i.e. HARQ-ACK adopts at least one of PUCCH format 2, 3 and 4, the total number of bits of the uplink control signaling to be transmitted is O UCI = O ACK + O UEI The bit of HARQ-ACK is in front, and the bit of UEI is in back. The total number of bits of the uplink control signaling to be transmitted is compared with the upper limit of the number of bits supported by the uplink physical control channel resource.

[0096] For example, if O ACK + O UEI is greater than the upper limit of the number of bits supported by the uplink physical control channel resource, O ACK ≤ the upper limit of the number of bits supported by the uplink physical control channel resource, only HARQ-ACK is transmitted, and UEI is discarded.

[0097] Wherein, O ACK represents the number of bits of HARQ-ACK to be transmitted, O UEI represents the number of bits of UEI to be transmitted, UEI is arranged in ascending order according to the value of its signaling identifier (ID). Since the priority of HARQ-ACK is higher than that of UEI, the information bits of HARQ-ACK are arranged in front of the information bits of UEI.

[0098] In a possible implementation, the uplink control information to be transmitted is UEI, HARQ-ACK and SR, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between UEI, HARQ-ACK and SR.

[0099] The multiplexing rule between UEI, HARQ-ACK and SR will be introduced below.

[0100] In the case that the uplink physical channel format of HARQ-ACK is 0, i.e. HARQ-ACK adopts PUCCH format 0, the mapping sequence of 1-bit HARQ-ACK information, positive SR and positive UEI on PUCCH format 0 is shown in Table 5.

[0101] Table 5

[0102] In case that the positive SR, the positive UEI and the 2-bit HARQ-ACK information exist simultaneously, the terminal device first performs conflict processing on the positive SR and the positive UEI, and determines one uplink control information from the positive SR and the positive UEI to be carried on the 2-bit HARQ-ACK.

[0103] In an example, the terminal device can compare the starting time slots of the positive SR and the positive UEI, and carry the uplink control information with the earlier starting time slot on the 2-bit HARQ-ACK, and discard the other uplink control information; in case that the starting time slots of the two are the same, the terminal device can carry one of the uplink control information at random or a predefined one (for example, the UEI is selected at this time) on the 2-bit HARQ-ACK, and discard the other uplink control information.

[0104] In another example, the terminal device can compare the priorities of the positive SR and the positive UEI, and carry the uplink control information with the higher priority on the 2-bit HARQ-ACK, and discard the other uplink control information. For example, when the positive SR is the positive SR-LRR, the positive SR-LRR has a higher priority than the positive UEI, and the positive SR-LRR is carried on the 2-bit HARQ-ACK, and the positive UEI is discarded; in case that the priorities of the positive SR and the positive UEI are the same, the terminal device can compare the starting time slots of the positive SR and the positive UEI, and carry the uplink control information with the earlier starting time slot on the 2-bit HARQ-ACK, and discard the other uplink control information; in case that the starting time slots of the two are the same, the terminal device can carry one of the uplink control information at random on the 2-bit HARQ-ACK, and discard the other uplink control information.

[0105] In case that the uplink physical channel format of the HARQ-ACK is 1 or 0, i.e. the HARQ-ACK adopts the PUCCH format 1 or 0, the terminal device can perform conflict processing on the positive SR and the positive UEI, and determine one uplink control information from the positive SR and the positive UEI to be carried on the 2-bit HARQ-ACK. For the convenience of subsequent description, the determination of one uplink control information from the positive SR and the positive UEI can be referred to as the first uplink control information.

[0106] If the uplink physical channel format of the HARQ-ACK is 0, it is determined to transmit the HARQ-ACK, and it is determined that the uplink physical control channel resource carrying the HARQ-ACK is the uplink physical control channel of the HARQ-ACK.

[0107] If the uplink physical channel format of the HARQ-ACK is 1, 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 positive first uplink control information. In the case where the uplink physical control channel format of the first uplink control information is 1 and the first uplink control information is positive first uplink control information, it is determined that the HARQ-ACK is sent, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the first uplink control information. Otherwise, it is determined that the ACK / NACK is sent, and the uplink physical control channel resource carrying the ACK / NACK is determined to be the uplink physical control channel of the HARQ-ACK.

[0108] In a possible implementation, the uplink physical channel format of the HARQ-ACK is 1, that is, the HARQ-ACK uses the PUCCH format 1, and the terminal device determines the uplink physical channel format of the SR and the UEI. Based on the uplink physical channel format of the SR and the UEI, at least one uplink control information and an uplink physical control channel resource for carrying the at least one uplink control information are determined from the to-be-transmitted uplink control information.

[0109] For example, in the case where the uplink physical channel format of the SR and the UEI is both 0, it is determined that only the HARQ-ACK is sent, and the SR and the UEI are discarded.

[0110] The terminal device determines that the uplink physical channel format of one of the SR and the UEI is 1, and the uplink physical channel format of the other uplink control information is 0. In this case, if the uplink control information with the uplink physical channel format of 1 is positive, it is determined that the HARQ-ACK is sent, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the positive uplink control information with the uplink physical channel format of 1. If the uplink control information with the uplink physical channel format of 1 is negative, it is determined that the ACK / NACK is sent, and the uplink physical control channel resource carrying the ACK / NACK is determined to be the uplink physical control channel of the HARQ-ACK.

[0111] In a case that the uplink physical channel format of the SR and the UEI are both 1, in a case that the SR is positive SR and the UEI is negative UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the positive SR; in a case that the SR is negative SR and the UEI is positive UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the positive UEI; in a case that the SR is positive SR and the UEI is positive UEI, the starting time slot of the SR and the UEI is determined, if the starting time slot of the SR is earlier than the starting time slot of the UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the SR, if the starting time slot of the SR is later than the starting time slot of the UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of the UEI, if the starting time slot of the SR is the same as the starting time slot of the UEI, it is determined to send the HARQ-ACK, and the uplink physical control channel resource carrying the HARQ-ACK is determined to be the uplink physical control channel of any one of the SR and the UEI.

[0112] In a possible implementation, in a case that the uplink physical channel format of the HARQ-ACK is at least one of 2, 3 and 4, that is, in a case that the HARQ-ACK adopts at least one of PUCCH format 2, 3 and 4, it is determined to send the HARQ-ACK, the SR and the UEI simultaneously, and the uplink physical control channel resource carrying the HARQ-ACK, the SR and the UEI is determined to be the uplink physical control channel of the HARQ-ACK.

[0113] In this case, if the HARQ-ACK, the SR and the UEI are separately encoded, the total number of bits O UCI ACK of the uplink control signaling to be sent is SR UEI , wherein O SR represents the number of bits of the SR to be sent.

[0114] If the UEI is configured with K1 resources and the SR is configured with K2 resources, the number of bits required for transmitting the UEI is The UEI is arranged in ascending order of the value of the signaling ID. The number of bits required for transmitting the SR is The SR is arranged in ascending order of the value of the scheduling request identifier. In this case,

[0115] ​​In case of joint encoding of SR and UEI, if UEI is configured with K1 resources and SR is configured with K2 resources, the joint encoded SR and UEI occupy bits, where K1 represents the number of UEI occurrences in a time slot, K2 represents the number of SR occurrences in a time slot,

[0116] In an example, the resources of SR are in front, and SR is arranged in ascending order of the value of the scheduling request identifier, and the resources of UEI are in the back, and UEI is arranged in ascending order of the value of its signaling ID.

[0117] In a 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.

[0118] The multiplexing rule between UEI and CSI report is introduced as follows.

[0119] The uplink physical channel format of the CSI report is at least one of 2, 3, and 4, and the total number of bits O UCI of the uplink control signaling to be sent is UEI +O CSI , O CSI represents the number of bits required to transmit the CSI report, UEI is in front of the CSI report, and UEI is arranged in ascending order of the value of its signaling ID.

[0120] In a 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 between UEI, SR, and CSI report.

[0121] The multiplexing rule between UEI, SR, and CSI report is introduced as follows.

[0122] The uplink physical channel format of the CSI report is one of 2, 3, and 4, and the uplink physical control channel resource for carrying UEI, SR, and CSI report is determined to be the uplink physical control channel of the CSI report.

[0123] In an example, the total number of bits O UCI of the uplink control signaling to be sent is ACK +O SR +O UEI +O CSIAccording to the priority of the UEI, the SR and the CSI report, and the upper limit of the number of bits supported by the uplink physical control channel resource of the CSI report, a first number of bits of the first channel indication, a second number of bits of the CSI report, and a third number of bits of the SR can be determined from the uplink control information to be transmitted.

[0124] In a case where the UEI, the SR and the CSI report are separately encoded, the uplink physical control channel resource based on the CSI report can transmit 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.

[0125] The first number of bits of the UEI to be transmitted can be represented as O UEI The first number of bits of the UEI to be transmitted can be represented as O The third number of bits of the SR to be transmitted can be represented as The SR is arranged in ascending order of the value of the scheduling request identifier, and the resource of the UEI is arranged in ascending order of the value of the signaling ID of the UEI.

[0126] In a case where the CSI report, the SR and the UEI are jointly encoded, the number of bits required for transmitting the CSI report, the SR and the UEI is the sum of the number of bits after jointly encoding the SR and the UEI, and the number of bits required for the CSI report, wherein the first number of bits of the first channel indication and the third number of bits of the SR are jointly encoded to obtain fourth number of bits of joint encoding information, and the fourth number of bits Or

[0127] In a possible implementation, the uplink control information to be transmitted is the UEI, the HARQ-ACK and the CSI report, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between the UEI, the HARQ-ACK and the CSI report.

[0128] The multiplexing rule between the UEI, the HARQ-ACK and the CSI report is similar to the multiplexing rule between the existing HARQ-ACK, the CSI and the SR, and thus will not be described herein.

[0129] In a possible implementation, the uplink control information to be transmitted is the UEI, the SR, the HARQ-ACK and the CSI report, and the multiplexing rule corresponding to the uplink control information to be transmitted is the multiplexing rule between the UEI, the SR, the HARQ-ACK and the CSI report.

[0130] The multiplexing rules between UEI, SR, HARQ-ACK and CSI report are introduced as follows.

[0131] According to the priority among HARQ-ACK, SR, first channel indication, CSI report and the upper limit of the number of bits supported by the uplink physical control channel resource, the fifth number of bits of HARQ-ACK, the sixth number of bits of SR, the seventh number of bits of the first channel indication and the eighth number of bits of CSI report can be determined from the uplink control information to be transmitted; and are sequentially carried in the uplink physical control channel resource for transmission.

[0132] Based on the uplink physical control channel resource, the fifth number of bits of HARQ-ACK, the sixth number of bits of SR, the seventh number of bits of the first channel indication and the eighth number of bits of CSI report are transmitted.

[0133] For example, in the case of separate encoding of UEI, SR, HARQ-ACK and CSI report, the seventh number of bits required for transmitting UEI can be represented as UEI is arranged in ascending order of the value of its signaling ID.

[0134] In the case of UEI being a dedicated SR, the number of bits required for transmitting UEI can be represented as or

[0135] In one possible implementation, the uplink control information to be transmitted includes one or more CSI reports and 0 or more HARQ-ACK, SR and UEI. HARQ-ACK is used to respond to an indication of semi-persistent scheduling (SPS) PDSCH reception. If any CSI report overlaps, and the terminal device is configured with a multi-CSI-PUCCH-ResourceList, the number of configured resources is less than or equal to 2, and PUCCH 2 / 3 / 4 is arranged in ascending order of the number of bits that can be carried.

[0136] In this case, if the number of bits of the uplink control information that can be transmitted the terminal device uses PUCCH 0; if the number of bits of the uplink control information that can be transmitted and The terminal device transmits the HARQ-ACK, the SR, the UEI and the CSI report by using the PUCCH resource j+1; otherwise, the terminal device transmits the CSI report with high priority and the HARQ-ACK, the SR and the UEI by using the PUCCH resource j-1.

[0137] wherein, is an uplink transmission scheduling bandwidth, in the form of a resource block (RB) number; is the controllable subcarrier number corresponding to each RB in different PUCCH formats; is the OFDM symbol length corresponding to different PUCCH formats; Q m is a modulation order; r is a maximum code rate.

[0138] In the embodiments of the present application, in the case of multiple CSI reports, if the multiple CSI reports conflict, the priority of the multiple CSI reports needs to be determined. For the CSI report of the beam report transmission process for UE-initiated / event-driven beam reporting.

[0139] For the convenience of description, the CSI report of the beam report transmission process for UE-initiated / event-driven beam reporting can be represented as the CSI report of UEI.

[0140] In the embodiments of the present application, the priority order of the CSI report of UEI can be configured and indicated by the network device.

[0141] In some examples, the priority of the CSI report of UEI is less than the priority of the LTM CSI report, and greater than the priority of other CSI reports.

[0142] In some examples, the priority of the CSI report of UEI is greater than the priority of the LTM CSI report, and the priority of the LTM CSI report is greater than the priority of other CSI reports.

[0143] In some examples, the priority of the CSI report of UEI in Mode A is less than the priority of the LTM CSI report, and greater than the priority of the CSI report of UEI in Mode B, and the priority of the CSI report of UEI in Mode B is greater than the priority of other CSI reports.

[0144] In some examples, the priority of the CSI report of the UEI of Mode B is less than the priority of the LTM CSI report, and greater than the priority of the CSI report of the UEI of Mode A, the priority of the CSI report of the UEI of Mode A is greater than the priority of other CSI reports.

[0145] In some examples, the priority of the CSI report of the UEI of Mode B is greater than the priority of the CSI report of the UEI of Mode A, the priority of the CSI report of the UEI of Mode A is greater than the priority of the LTM CSI report, the priority of the LTM CSI report is greater than the priority of other CSI reports.

[0146] In some examples, the priority of the CSI report of the UEI of Mode A is greater than the priority of the CSI report of the UEI of Mode B, the priority of the CSI report of the UEI of Mode B is greater than the priority of the LTM CSI report, the priority of the LTM CSI report is greater than the priority of other CSI reports.

[0147] In the embodiments of the present application, the priority value of the CSI report can be calculated according to the following formula (1), Pri iCSI (y, k, c, s) = 2N cells M s y+N cells M s k+M s k+M s c+s (1)

[0148] Wherein, if y = 0, it means that the PUSCH carries the aperiodic CSI report; if y = 1, it means that the PUSCH carries the semi-persistent CSI report; if y = 2, it means that the PUCCH carries the semi-persistent CSI report; if y = 3, it means that the PUCCH carries the periodic CSI report.

[0149] If k = 0, it means that the CSI report carries L1-RSRP or L1-SINR; if k = 1, it means that the CSI report does not carry L1-RSRP or L1-SINR.

[0150] c is the service cell index, N cellsis the value of the higher layer parameter maxNrofServingCells; s is the report configuration identifier (reportConfigID), M s is the value of the higher layer parameter maxNrofCSI-ReportConfigurations.

[0151] In an 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.

[0152] In an example, the value of y is related to the reporting mode of the event. For example, after the event occurs, the terminal device only reports the CSI report once, similar to the existing aperiodic CSI report; after the event occurs, the terminal device can continuously report the CSI report, similar to the existing semi-persistent CSI report.

[0153] In an example, the value of y is related to the reporting mode of the event. For example, using mode 1, the DCI triggers the aperiodic CSI report; using mode 2, the DCI triggers the semi-persistent CSI report.

[0154] M s represents the maximum number of event-triggered CSI reports that can be configured in one component carrier (CC).

[0155] For example, in the case where the network device only configures Mode A, M s represents the maximum number of event-triggered CSI reports for Mode A that can be configured in one CC.

[0156] In the case where the network device only configures Mode B, M s represents the maximum number of event-triggered CSI reports for Mode B that can be configured in one CC.

[0157] In an example, the value of y is related to the CSI channel type carried. For example, the priority of the dynamic grant physical uplink shared channel (DG-PUSCH) is higher than the priority of the configured grant physical uplink shared channel (CG-PUSCH), or the priority of Mode A is higher than the priority of Mode B.

[0158] It should be noted that in mode B, the CG-PUSCH is a CG 1 PUSCH used to carry the CSI report. In some embodiments, the CG 1 PUSCH carrying the CSI report can also be used to send other uplink control signaling and / or uplink data.

[0159] In a possible implementation, when the candidate PUSCHs include DCI-scheduled first PUSCHs, CG-configured or semi-persistent configured (SP) second PUSCHs on a physical uplink shared channel (PUSCH), the UCI is multiplexed on one of the first PUSCHs based on multiplexing timing constraints, and the priority of the multiplexed PUSCH type is that the priority of the DG PUSCH is greater than the priority of the SP PUSCH, and the priority of the SP PUSCH is greater than the priority of the CG 1 PUSCH.

[0160] In the embodiments of the present application, there can be an overlap between the non-repeated PUCCH and the PUSCH, as shown in Table 6, which lists the multiplexing rules when there is an overlap between the non-repeated PUCCH and the PUSCH.

[0161] Table 6

[0162] As shown in Table 6, when the to-be-transmitted uplink control information includes a positive first channel indication, and the physical uplink shared channel resource of the to-be-transmitted uplink control information and the physical uplink shared channel resource not carrying uplink shared channel data overlap, the physical uplink shared channel resource is discarded, and the uplink control information is transmitted based on the uplink physical control channel resource.

[0163] When the to-be-transmitted uplink control information includes a positive first channel indication, and the physical uplink shared channel resource of the to-be-transmitted uplink control information and the physical uplink shared channel resource carrying uplink shared channel data overlap, the physical uplink shared channel resource of the to-be-transmitted uplink control information is discarded, and the physical uplink shared channel resource is transmitted.

[0164] When the to-be-transmitted uplink control information includes a positive first channel indication and a positive SR, and the physical uplink shared channel resource of the to-be-transmitted uplink control information and the physical uplink shared channel resource not carrying uplink shared channel data overlap, the physical uplink shared channel resource is discarded, and the uplink control information is transmitted based on the uplink physical control channel resource.

[0165] When the uplink control information to be transmitted includes a positive first channel indication and a positive SR, and the physical uplink shared channel resource of the uplink control information to be transmitted and the physical uplink shared channel resource carrying uplink shared channel data overlap, the uplink physical control channel resource of the uplink control information is discarded, and the physical uplink shared channel resource is transmitted.

[0166] To sum up, the multiplexing rule of the uplink control information is updated in the embodiment of the application. In the case that there is a newly added type of uplink control information, the uplink control information can be transmitted based on the updated multiplexing rule.
