Description

Technical Field

[0001] The present application relates to a wireless communication network, for example, to a method and device for multiplexing uplink control information. Background Art

[0002] In the fifth generation mobile communication technology (5G), also known as New Radio (NR), NR-based Access to Unlicensed Spectrum (NR-U) technology has great application prospects in various fields such as the Internet of Things and factory automation.

[0003] However, the use of unlicensed spectrum needs to comply with certain regulations. For example, the device must perform Listen Before Talk (LBT) before sending data using an unlicensed carrier. LBT can also be called Clear Channel Assessment (CCA). Only devices that succeed in LBT can send data on unlicensed carriers. In NR-U unscheduled (or configured grant, or autonomous uplink) transmission, the unscheduled transmission physical uplink shared channel (PUSCH) contains uplink control information (UCI), which contains at least the hybrid automatic repeat-request (HARQ) process identifier (ID), new date indicator (NDI), redundancy version (RV) ID and channel occupancy time (COT) sharing information. The UCI may also include a user equipment (UE) ID, a cyclic redundancy check (CRC), a PUSCH start and end position / time slot, a resource configuration index, transmission parameters, and code block group transmission information (CBGTI).

[0004] However, NR-U scheduling-free transmission involves transmission in multiple transmission time intervals (TTIs). The PUSCH transmission of each TTI contains a complete UCI, which will incur a large overhead and affect data transmission efficiency. Summary of the invention

[0024] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 A flowchart of an uplink control information multiplexing method provided by an embodiment, such as Figure 1 As shown, the method provided in this embodiment includes the following steps.

[0026] Step S1010: When a COT includes PUSCH scheduling-free transmissions of N consecutive TTIs, the complete UCI is multiplexed for the PUSCH scheduling-free transmissions of the first K TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs, where K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2.

[0027] The uplink control information multiplexing method provided in this embodiment is applied to a UE, or a terminal, in a wireless communication network. The UE uses an uplink channel to send uplink information in the wireless communication network.

[0028] In the scheduling-free transmission of NR-U, before the scheduling-free configuration resources arrive, the UE needs to perform LBT first. If the LBT is successful, a COT will be occupied, and the UE uses the COT to transmit data. Each COT contains multiple TTIs, each TTI is used to carry a PUSCH transmission, and the PUSCH of each TTI can transmit different TBs or the same TB. If different TTIs transmit the same TB, the TTIs transmitting the same TB use the same HARQ process ID. If different TTIs transmit different TBs, the TTIs transmitting different TBs use different HARQ process IDs.

[0029] When a COT includes PUSCH scheduling-free transmission of multiple TTIs, if each TTI includes a complete UCI, a large overhead is required.

[0030] In this embodiment, when a COT contains PUSCH scheduling-free transmissions of N consecutive TTIs, the PUSCH scheduling-free transmissions of the first K TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs are multiplexed with complete UCI. K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2, that is, a COT contains at least two consecutive TTIs of PUSCH scheduling-free transmissions, and at least the PUSCH scheduling-free transmissions of the consecutive TTIs starting from the first TTI multiplex the complete UCI. If K is equal to N, it means that all TTIs of the COT multiplex the complete UCI, which will still result in a large overhead. Therefore, K needs to be less than N, that is, only a part of the TTIs in the COT multiplex the complete UCI.

[0031] The complete UCI includes the complete UCI for uplink scheduling, including at least HARQ process ID, NDI, RVID, and COT shared information. The complete UCI may also include at least one of the following information: UE ID, CRC, PUSCH start and end position / time slot, resource configuration index, CBGTI. Among them, the resource configuration index is used to indicate the scheduling-free configuration resources used for this transmission when multiple sets of scheduling-free resources are configured for the UE. The transmission parameters include at least one of the modulation and coding scheme (MCS), precoding matrix indicator (PMI), rank indicator (RI), and sounding reference signal (SRS) resource indicator (SRSresource indicator, SRI).

[0032] Step S1020: multiplex partial UCI for the remaining NK TTIs of PUSCH scheduling-free transmission in the N consecutive TTIs of PUSCH scheduling-free transmission, where the information included in the partial UCI is a subset of the information included in the complete UCI.

[0033] In order to reduce the UCI overhead of PUSCH scheduling-free transmission of multiple consecutive TTIs, in this embodiment, after the PUSCH scheduling-free transmission of the first K TTIs in the PUSCH scheduling-free transmission of N consecutive TTIs in one COT is multiplexed with the complete UCI, the PUSCH scheduling-free transmission of the remaining NK TTIs in the PUSCH scheduling-free transmission of N consecutive TTIs is multiplexed with partial UCI. The information contained in the partial UCI is a subset of the information contained in the complete UCI.

[0034] That is, in the PUSCH scheduling-free transmission of N consecutive TTIs, the remaining NK TTIs only include part of the complete UCI information, and the other part of the complete UCI information is determined or implicitly indicated based on other information. In this way, when the base station receives the PUSCH of N consecutive TTIs sent by the UE, it will be able to determine the complete UCI of each TTI based on other information, thereby achieving correct reception and processing of the PUSCH.

[0035] The scenario of multiplexing partial UCI in NK TTIs may be: before COT sharing or before the uplink (Uplink, UL) to downlink (Downlink, DL) switching, there are a total of N TTIs of PUSCH transmission, and the PUSCH transmission of the remaining NK TTIs contains partial UCI, and the information contained in the partial UCI is a subset of the information contained in the complete UCI. Or due to COT sharing or other reasons, multiple uplink and downlink switching of UL-to-DL-to-UL may occur in COT. After DL-to-UL switching, in the case of multiple TTI transmissions in UL transmission, the PUSCH transmission of the first K TTIs in the multiple TTI transmissions of UL transmission contains complete UCI, and the PUSCH transmission of other TTIs contains partial UCI.

[0036] Partial UCI can contain part of the information in the complete UCI. The information contained in partial UCI can include the following situations:

[0037] 1. Partial UCI includes HARQ process ID, NDI, RVID, and the COT sharing information of partial UCI is determined based on the COT sharing information in the complete UCI of the previous K TTIs in the same COT. In addition, partial UCI may also include CBGTI.

[0038] 2. Some UCIs include HARQ process ID and NDI. The COT sharing information of some UCIs is determined based on the COT sharing information in the complete UCIs of the first K TTIs in the same COT. The RVID of some UCIs is determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0039] 3. Some UCIs include HARQ process IDs, and the COT sharing information of some UCIs is determined based on the COT sharing information in the complete UCIs of the previous K TTIs in the same COT. The RVID and NDI of some UCIs are determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0040] In one embodiment, if the PUSCH scheduling-free transmission of N consecutive TTIs is the same as the transport block TB, the NDI in the partial UCI is the same as the NDI in the complete UCI of the first K TTIs in the same COT.

[0041] 4. The COT sharing information of some UCIs is determined based on the COT sharing information of the complete UCIs of the previous K TTIs in the same COT. The RVID, NDI, and HARQ process ID of some UCIs are determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0042] In one embodiment, if the PUSCH scheduling-free transmission of N consecutive TTIs is the same transport block TB, the HARQ process ID in the partial UCI is the same as the HARQ process ID in the complete UCI of the first K TTIs in the same COT.

[0043] In one embodiment, the LBT type and LBT priority in the COT shared information in the partial UCI are the same as the LBT type and LBT priority in the COT shared information in the complete UCI of the first K TTIs in the same COT, and the remaining COT length in the COT shared information in the partial UCI is determined based on the remaining COT length in the COT shared information in the complete UCI of the first K TTIs in the same COT minus the length of the TTI that has been transmitted and does not include the complete UCI.

[0044] In one embodiment, the RVID in some UCIs is determined according to the HARQ process ID and / or NDI. Specifically, if the NDI of an adjacent non-scheduled transmission that is the same as the HARQ process ID is different from the NDI used for the PUSCH transmission transmitted using the HARQ process ID, the RVID is 0; if the NDI of an adjacent non-scheduled transmission that is the same as the HARQ process ID is the same as the NDI used for the PUSCH transmission transmitted using the HARQ process ID, the adjacent non-scheduled transmission and the current transmission are sent according to the predefined redundant version RV pattern; in the non-scheduled transmission of N consecutive TTIs within the COT, the PUSCH transmission using the same HARQ process ID is sent according to the predefined RV pattern. For example, the predefined RV pattern is {0,2,3,1}, and the RVID of the adjacent PUSCH transmission that is the same as the HARQ process ID is 0, then the RVID of the current PUSCH transmission is 2; similarly, if the RVID of the adjacent PUSCH transmission that is the same as the HARQ process ID is 2, then the RVID of the current PUSCH transmission is 3. In multi-TTI transmission of COT, the RVID used for TTI transmission with the same HARQ process ID is determined according to a predefined pattern; if the predefined RV pattern is {0,2,3,1}, in multi-TTI transmission, there are 4 TTIs with the same HARQ process ID, then the RVIDs of the PUSCH repeated transmission corresponding to the order in which the HARQ process IDs appear are 0, 2, 3, and 1 respectively.

[0045] In one embodiment, the NDI in part of the UCI is determined according to the HARQ process ID and / or the downlink feedback indicator (Downlink Feedback Indicator, DFI) and / or scheduling information. Specifically, if the DFI feedback of an adjacent unscheduled transmission with the same HARQ process ID is negative acknowledgment (NACK) and the base station does not schedule PUSCH retransmission of the HARQ process ID between the adjacent unscheduled transmission with the same HARQ process ID and the current transmission, then the NDI is the same as the NDI of an adjacent PUSCH transmission with the same HARQ process ID; if the DFI feedback of an adjacent unscheduled transmission with the same HARQ process ID is NACK and the base station schedules PUSCH retransmission of the HARQ process ID between the adjacent unscheduled transmission with the same HARQ process ID and the current transmission, then the NDI is different from the NDI used for the adjacent unscheduled transmission with the same HARQ process ID; if the DFI feedback of an adjacent unscheduled transmission with the same HARQ process ID is acknowledgment (ACK), then the NDI is different from the NDI used for the adjacent unscheduled transmission with the same HARQ process ID; in the unscheduled transmissions of N consecutive TTIs of the COT, the NDI corresponding to the TTI transmissions with the same HARQ process ID is the same.

[0046] In one embodiment, the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI. Specifically, if the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI, and the HARQ process ID determined is an occupied and / or unreleased HARQ process ID, then the increment is continued based on the determined HARQ process ID to determine the use of the first available HARQ process ID; if the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI, and the HARQ process ID determined exceeds the maximum HARQ process ID, then the increment is continued from the minimum HARQ process ID configured for scheduling-free transmission. For example: in multi-TTI transmission, TTIs are numbered in time order, and the multi-TTIs are N TTIs in total. The first TTI in the N TTIs is numbered n, and the multi-TTIs are numbered n, n+1, ..., n+N-1. The TTI where the complete UCI is located is TTI n and the HARQ process ID in the UCI is k, then the process of TTI n+1 is k+1. If process k+1 is occupied, it will continue to increase to process k+2. If process k+2 is available, the HARQ process used by the PUSCH transmitted on TTI n+1 is k+2.

[0047] In the above cases 1-4, the UE ID, PUSCH start and end position / time slot, resource configuration index, and transmission parameters in the partial UCI are determined according to the UE ID, PUSCH start and end position / time slot, resource configuration index, and transmission parameters in the complete UCI of the previous K TTIs in the same COT. The CRC in the partial UCI determines whether to include and / or the bit length of the CRC according to the overhead size of the partial UCI.

[0048] The uplink control information multiplexing method provided in this embodiment, when a COT contains PUSCH scheduling-free transmission of N consecutive TTIs, multiplexes the complete UCI for the PUSCH scheduling-free transmission of the first K TTIs in the PUSCH scheduling-free transmission of N consecutive TTIs, where K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2, and then multiplexes partial UCI for the PUSCH scheduling-free transmission of the remaining NK TTIs in the PUSCH scheduling-free transmission of N consecutive TTIs, and the information contained in the partial UCI is a subset of the information contained in the complete UCI, which will be able to reduce the overhead of UCI in the scheduling-free transmission and improve data transmission efficiency.

[0049] Figure 2A flowchart of another uplink control information multiplexing method provided by an embodiment, such as Figure 2 As shown, the method provided in this embodiment includes the following steps.

[0050] Step S2010, receiving PUSCH scheduling-free transmissions of N consecutive TTIs within a COT, the PUSCH scheduling-free transmissions of the first K TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs multiplex the complete UCI, and the PUSCH scheduling-free transmissions of the remaining NK TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs multiplex the partial UCI, and the information contained in the partial UCI is a subset of the information contained in the complete UCI, wherein K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2.

[0051] The uplink control information multiplexing method provided in this embodiment is applied to a base station in a wireless communication network. A base station UE receives uplink information sent by a UE through an uplink channel in the wireless communication network.

[0052] The base station receives PUSCH scheduling-free transmissions of N consecutive TTIs within a COT, the PUSCH scheduling-free transmissions of the first K TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs multiplex the complete UCI, and the PUSCH scheduling-free transmissions of the remaining NK TTIs among the PUSCH scheduling-free transmissions of N consecutive TTIs multiplex the partial UCI, and the information contained in the partial UCI is a subset of the information contained in the complete UCI, where K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2.

[0053] In the NR-U scheduling-free transmission, before the scheduling-free configuration resources arrive, the UE needs to perform LBT first. If the LBT is successful, a COT will be occupied, and the UE uses the COT to transmit data. Each COT contains multiple TTIs, each TTI is used to carry a PUSCH transmission, and the PUSCH of each TTI can transmit different TBs or the same TB. When a COT contains multiple TTIs of PUSCH scheduling-free transmission, if each TTI includes a complete UCI, it will take up a lot of overhead. Therefore, the UE can multiplex the complete UCI for the PUSCH scheduling-free transmission of the first K TTIs of the PUSCH scheduling-free transmission of N consecutive TTIs in a COT, and multiplex partial UCI for the PUSCH scheduling-free transmission of the remaining NK TTIs.

[0054] The complete UCI includes the complete UCI for uplink scheduling, including at least HARQ process ID, NDI, RVID, and COT shared information. The complete UCI may also include at least one of the following information: UE ID, CRC, PUSCH start and end position / time slot, resource configuration index, and CBGTI. Among them, the resource configuration index is used to indicate the scheduling-free configuration resources used for this transmission when multiple sets of scheduling-free resources are configured for the UE, and the transmission parameters include at least one of the modulation and coding scheme MCS, the precoding matrix indication PMI, the rank indication RI, and the SRI.

[0055] Step S2020: According to the complete UCI of the PUSCH non-scheduling transmission of the first K TTIs in the PUSCH non-scheduling transmission of N consecutive TTIs, the partial UCI of the PUSCH non-scheduling transmission of the remaining NK TTIs in the PUSCH non-scheduling transmission of N consecutive TTIs is supplemented as the complete UCI.

[0056] Since the base station needs to obtain the complete UCI of the PUSCH of each TTI in order to normally receive and process data, the base station needs to supplement the partial UCI of the PUSCH unscheduled transmission of the remaining NK TTIs in the PUSCH unscheduled transmission of N consecutive TTIs into the complete UCI based on the complete UCI of the PUSCH unscheduled transmission of the first K TTIs in the PUSCH unscheduled transmission of N consecutive TTIs.

[0057] Partial UCI can contain part of the information in the complete UCI. The information contained in partial UCI can include the following situations:

[0058] 1. Partial UCI includes HARQ process ID, NDI, RVID, and the COT sharing information of partial UCI is determined based on the COT sharing information in the complete UCI of the previous K TTIs in the same COT. In addition, partial UCI may also include CBGTI.

[0059] 2. Some UCIs include HARQ process ID and NDI. The COT sharing information of some UCIs is determined based on the COT sharing information in the complete UCIs of the first K TTIs in the same COT. The RVID of some UCIs is determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0060] 3. Some UCIs include HARQ process IDs, and the COT sharing information of some UCIs is determined based on the COT sharing information in the complete UCIs of the previous K TTIs in the same COT. The RVID and NDI of some UCIs are determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0061] In one embodiment, if the PUSCH scheduling-free transmission of N consecutive TTIs is the same as the transport block TB, the NDI in the partial UCI is the same as the NDI in the complete UCI of the first K TTIs in the same COT.

[0062] 4. The COT sharing information of some UCIs is determined based on the COT sharing information of the complete UCIs of the previous K TTIs in the same COT. The RVID, NDI, and HARQ process ID of some UCIs are determined by implicit indication. In addition, some UCIs may also include CBGTI.

[0063] In one embodiment, if the PUSCH scheduling-free transmission of N consecutive TTIs is the same transport block TB, the HARQ process ID in the partial UCI is the same as the HARQ process ID in the complete UCI of the first K TTIs in the same COT.

[0064] In one embodiment, the LBT type and LBT priority in the COT sharing information in the partial UCI are the same as the LBT type and LBT priority in the COT sharing information in the complete UCI of the first K TTIs in the same COT, and the remaining COT length in the COT sharing information in the partial UCI is determined based on the remaining COT length in the COT sharing information in the complete UCI of the first K TTIs in the same COT minus the length of the received TTI that does not contain the complete UCI.

[0065] In one embodiment, the RVID in some UCIs is determined according to the HARQ process ID and / or NDI. Specifically, if the NDI of the nearest non-scheduled reception that is the same as the HARQ process ID is different from the NDI used for the PUSCH reception transmitted using the HARQ process ID, the RVID is 0; if the NDI of the nearest non-scheduled reception that is the same as the HARQ process ID is the same as the NDI used for the PUSCH reception transmitted using the HARQ process ID, the nearest non-scheduled reception and the current reception are sent according to the predefined redundant version RV pattern; in the non-scheduled reception of N consecutive TTIs within the COT, the PUSCH reception using the same HARQ process ID is sent according to the predefined RV pattern. For example, the predefined RV pattern is {0,2,3,1}, and the RVID of the nearest PUSCH transmission that is the same as the HARQ process ID is 0, then the RVID of the current PUSCH transmission is 2; similarly, if the RVID of the nearest PUSCH transmission that is the same as the HARQ process ID is 2, then the RVID of the current PUSCH transmission is 3. In multi-TTI transmission of COT, the RVID used for TTI transmission with the same HARQ process ID is determined according to a predefined pattern; if the predefined RV pattern is {0,2,3,1}, in multi-TTI transmission, there are 4 TTIs with the same HARQ process ID, then the RVIDs of the PUSCH repeated transmission corresponding to the order in which the HARQ process IDs appear are 0, 2, 3, and 1 respectively.

[0066] In one embodiment, the NDI in some UCIs is determined according to the HARQ process ID and / or DFI and / or scheduling information. Specifically, if the DFI feedback of the adjacent unscheduled reception with the same HARQ process ID is NACK and the base station does not schedule the PUSCH retransmission of the HARQ process ID between the adjacent unscheduled reception with the same HARQ process ID and the current reception, then the NDI is the same as the NDI of the adjacent PUSCH reception with the same HARQ process ID; if the DFI feedback of the adjacent unscheduled reception with the same HARQ process ID is NACK and the base station schedules the PUSCH retransmission of the HARQ process ID between the adjacent unscheduled reception with the same HARQ process ID and the current reception, then the NDI is different from the NDI used for the adjacent unscheduled reception with the same HARQ process ID; if the DFI feedback of the adjacent unscheduled reception with the same HARQ process ID is ACK, then the NDI is different from the NDI used for the adjacent unscheduled reception with the same HARQ process ID; in the unscheduled reception of N consecutive TTIs of the COT, the NDI corresponding to the TTI reception with the same HARQ process ID is the same.

[0067] In one embodiment, the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI. Specifically, if the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI, and the HARQ process ID determined is an occupied and / or unreleased HARQ process ID, then the increment is continued based on the determined HARQ process ID to determine the use of the first available HARQ process ID; if the HARQ process ID in the partial UCI is incremented based on the HARQ process ID in the complete UCI of the first K TTIs in the same COT in the order of increasing TTI, and the HARQ process ID determined exceeds the maximum HARQ process ID, then the increment is continued from the minimum HARQ process ID configured for scheduling-free transmission. For example: in multi-TTI transmission, TTIs are numbered in time order, and the multi-TTIs are N TTIs in total. The first TTI in the N TTIs is numbered n, and the multi-TTIs are numbered n, n+1, ..., n+N-1. The TTI where the complete UCI is located is TTI n and the HARQ process ID in the UCI is k, then the process of TTI n+1 is k+1. If process k+1 is occupied, it will continue to increase to process k+2. If process k+2 is available, the HARQ process used by the PUSCH transmitted on TTI n+1 is k+2.

[0068] In the above cases 1-4, the UE ID, PUSCH start and end position / time slot, resource configuration index, and transmission parameters in the partial UCI are determined according to the UE ID, PUSCH start and end position / time slot, resource configuration index, and transmission parameters in the complete UCI of the previous K TTIs in the same COT. The CRC in the partial UCI determines whether to include and / or the bit length of the CRC according to the overhead size of the partial UCI.

[0069] The uplink control information multiplexing method provided in this embodiment receives PUSCH scheduling-free transmission of N consecutive TTIs within a COT, multiplexes complete UCI for PUSCH scheduling-free transmission of the first K TTIs in PUSCH scheduling-free transmission of N consecutive TTIs, and multiplexes partial UCI for PUSCH scheduling-free transmission of the remaining NK TTIs in PUSCH scheduling-free transmission of N consecutive TTIs, where the information contained in the partial UCI is a subset of the information contained in the complete UCI, wherein K is an integer greater than or equal to 1, and N is an integer greater than or equal to 2; based on the complete UCI of PUSCH scheduling-free transmission of the first K TTIs in PUSCH scheduling-free transmission of N consecutive TTIs, the partial UCI of PUSCH scheduling-free transmission of the remaining NK TTIs in PUSCH scheduling-free transmission of N consecutive TTIs is supplemented with the complete UCI, which will reduce the overhead of UCI in scheduling-free transmission and improve data transmission efficiency.

[0070] The uplink control information multiplexing method provided by the present application is described in detail with reference to several specific embodiments.

[0071] Embodiment 1

[0072] In the NR-U scheduling-free transmission, before the scheduling-free configuration resources arrive, the UE performs LBT. If the LBT is successful, a COT is occupied, and the UE uses the COT to transmit data. Each COT contains N TTIs, each TTI is used to carry a PUSCH transmission, and the PUSCH of each TTI can transmit different TBs or the same TB. If different TTIs transmit the same TB, the TTIs use the same HARQ process ID. If different TTIs transmit different TBs, the TTIs use different HARQ process IDs.

[0073] In the scheduling-free transmission of N TTIs, each TTI transmits a different TB, and the TTIs transmitting different TBs use different HARQ process IDs. The UE performs LBT before the arrival of the scheduling-free granted resource. If the LBT is successfully executed, the corresponding COT is occupied.
