Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, and more specifically, to an uplink transmission method and corresponding equipment. Background Technology

[0002] With the rapid development of the information industry, especially the growing demand from mobile internet and the Internet of Things (IoT), unprecedented challenges are being brought to future mobile communication technologies. According to the International Telecommunication Union (ITU) report ITU-R M. [IMT.BEYOND2020.TRAFFIC], it is projected that by 2020, mobile traffic will increase nearly 1000 times compared to 2010 (the 4G era), and the number of user-defined devices (UEs) will exceed 17 billion. As massive numbers of IoT devices gradually penetrate mobile communication networks, the number of connected devices will be even more staggering. To address these unprecedented challenges, the communications industry and academia have launched extensive research into fifth-generation mobile communication technology (5G) in preparation for the 2020s. Currently, the ITU report ITU-R M. [IMT.VISION] discusses the framework and overall goals of future 5G, providing detailed explanations of 5G's demand outlook, application scenarios, and key performance indicators. In response to the new demands of 5G, the ITU report ITU-R M. [IMT. FUTURE TECHNOLOGY TRENDS] provides information on technology trends related to 5G, aiming to address significant issues such as significantly improved system throughput, consistent user experience, scalability to support IoT, latency, energy efficiency, cost, network flexibility, support for emerging services, and flexible spectrum utilization. In 3GPP (3... rdThe first phase of work on 5G within the Generation Partnership Project (3GPP) is underway. To support more flexible scheduling, 3GPP has decided to support variable Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) feedback latency in 5G. In existing Long Term Evolution (LTE) systems, the time from downlink data reception to HARQ-ACK uplink transmission is fixed, for example, in Frequency Division Duplex (FDD) systems where the latency is four subframes. In Time Division Duplex (TDD) systems, a HARQ-ACK feedback latency is determined for the corresponding downlink subframe based on the uplink and downlink configuration. In 5G systems, whether FDD or TDD, the uplink time unit for HARQ-ACK feedback is variable for a given downlink time unit (e.g., downlink slot or downlink mini-slot). For example, the latency of HARQ-ACK feedback can be dynamically indicated through physical layer signaling, or different HARQ-ACK latency can be determined based on factors such as different services or user capabilities.

[0003] 3GPP has defined three main directions for 5G application scenarios: eMBB (enhanced mobile broadband), mMTC (massive machine-type communication), and URLLC (ultra-reliable and low-latency communication). eMBB aims to further improve data transmission rates on top of existing mobile broadband services to enhance user experience and achieve the ultimate communication experience between people. mMTC and URLLC are application scenarios for the Internet of Things (IoT), but they have different focuses: mMTC primarily addresses information interaction between people and things, while URLLC mainly reflects the communication needs between things themselves.

[0004] In 5G, eMBB and URLLC will adopt a joint networking approach, meaning that both URLLC and eMBB services will be supported within the same cell. Since URLLC services may be sparse, joint eMBB and URLLC networking can improve system spectrum efficiency compared to URLLC-only networking. When URLLC services are present in the system, they are prioritized; when there are no URLLC services or URLLC services consume minimal resources, eMBB services can be scheduled. Currently, when URLLC and eMBB services conflict, URLLC data and / or control information are transmitted first, resulting in a performance penalty for eMBB services. Therefore, optimizing the transmission of data and control information for eMBB services is a pressing issue that needs to be addressed. Summary of the Invention

[0005] The present invention is provided to at least solve the above-mentioned problems and to provide at least the following advantages.

[0006] According to one aspect of the present invention, a method performed by a second type of transceiver node in a wireless communication system is provided, comprising: receiving first type of data and / or first type of control signaling from a first type of transceiver node; determining second type of control signaling and a time unit for transmitting the second type of control signaling based on the first type of data and / or the first type of control signaling; and transmitting the second type of control signaling to the first type of transceiver node in the determined time unit.

[0007] Optionally, the second type of transceiver node is configured with two levels of priority for transmission to the first type of transceiver node. The two levels of priority include a first priority and a second priority that are different from each other. The first priority is higher than the second priority. The first priority is indicated by a first priority index and the second priority is indicated by a second priority index. When second type control signaling with different priority indices is multiplexed and transmitted on the same physical uplink control channel (PUCCH), the transmission power of the PUCCH is determined based on the total second type control signaling.

[0008] Optionally, for PUCCH format 2, PUCCH format 3, and PUCCH format 4, the PUCCH transmission power adjustment parameters for determining the PUCCH transmission power are calculated based on one or more of the following parameters included in the second type of control signaling: the number of HARQ-ACK information bits for power control, which is the sum of the number of HARQ-ACK information bits for power control in HARQ-ACK codebooks with different priority indices; the number of information bits for scheduling request (SR) and / or link recovery request (LRR), which is the sum of the number of information bits for SR and / or LRR with different priority indices, or the number of information bits for SR and / or LRR with the first priority index, or the number of information bits for SR and / or LRR with the second priority index; and the number of information bits for channel state information (CSI), which is the sum of the number of information bits for CSI with different priority indices; or the number of information bits for CSI with the first priority index; or the number of information bits for CSI with the second priority index.

[0009] Optionally, when the value corresponding to the transmission power of PUCCH is greater than the first threshold, only the second type of control signaling of the first priority index is transmitted and the second type of control signaling of the second priority index is not transmitted; or, only the second type of control signaling of the first priority index and a part of the second type of control signaling of the second priority index are transmitted, and the other part of the second type of control signaling of the second priority index is not transmitted.

[0010] Optionally, when the value corresponding to the transmission power of PUCCH calculated based on the second type of control signaling of the first priority index and the second type of control signaling of the partial second priority index is less than or equal to the first threshold value, the second type of control signaling of the partial second priority index is transmitted; otherwise, the second type of control signaling of the second priority index is not transmitted.

[0011] Optionally, when the value corresponding to the transmission power of PUCCH is greater than or equal to the first threshold value + Δ, only the second type of control signaling of the first priority index is transmitted and the second type of control signaling of the second priority index is not transmitted; or, only the second type of control signaling of the first priority index and a part of the second type of control signaling of the second priority index are transmitted, and the other part of the second type of control signaling of the second priority index is not transmitted, where Δ is a parameter greater than 0.

[0012] Optionally, when the value corresponding to the transmission power of PUCCH calculated based on the second type of control signaling of the first priority index and the second type of control signaling of the partial second priority index is less than or equal to the first threshold value, the second type of control signaling of the partial second priority index is transmitted; otherwise, the second type of control signaling of the second priority index is not transmitted.

[0013] Optionally, when Type II control signaling with different priority indices is multiplexed and transmitted on the same PUCCH, the transmission power of the PUCCH is determined based on the Type II control signaling with the first priority index.

[0014] Optionally, for PUCCH format 2, PUCCH format 3, and PUCCH format 4, the PUCCH transmission power adjustment parameters for determining the PUCCH transmission power are calculated based on one or more of the following parameters included in the second type of control signaling: the number of HARQ-ACK information bits for power control, which is the number of HARQ-ACK information bits for power control in the HARQ-ACK codebook of the first priority index; the number of SR and / or LRR information bits, which is the number of SR and / or LRR information bits in the first priority index; the number of Channel State Information (CSI) information bits, which is the number of CSI information bits in the first priority index; and the number of resource elements (REs) for transmitting the second type of control signaling of the first priority index.

[0015] Optionally, the PUCCH transmission power adjustment parameters are calculated according to the second type of control signaling with different priorities, and then the maximum or minimum value is taken to further determine the PUCCH transmission power.

[0016] Optionally, when second-type control signaling with the same priority index is multiplexed and transmitted on the same PUCCH, and when the second-type control signaling includes CSI part 1 of the first priority and CSI part 2 of the second priority, the transmission power of the PUCCH is determined based on at least one of CSI part 1 and CSI part 2.

[0017] Optionally, for PUCCH format 2, PUCCH format 3, and PUCCH format 4, where the number of Type II control signaling bits excluding CSI part 2 is less than or equal to 11, the PUCCH transmission power adjustment parameters for determining the PUCCH transmission power are calculated based on one or more of the following parameters included in the Type II control signaling: the number of information bits in CSI part 1; and the number of REs transmitting Type II control signaling excluding CSI part 2.

[0018] Optionally, for PUCCH format 2, PUCCH format 3, and PUCCH format 4, where the number of Type II control signaling bits excluding CSI part 2 is greater than 11, the PUCCH transmission power adjustment parameters for determining the PUCCH transmission power are calculated based on one or more of the following parameters included in the Type II control signaling: the number of information bits in CSI part 1; the number of bits in HARQ-ACK, and / or SR, and / or CRC in CSI part 1; and the number of REs transmitted for Type II control signaling excluding CSI part 2.

[0019] Optionally, when the value corresponding to the transmission power of PUCCH is greater than the first threshold, only the second type of control signaling excluding CSI part 2 is transmitted and CSI part 2 is not transmitted; when the value corresponding to the transmission power of PUCCH is greater than or equal to the first threshold + Δ, only the second type of control signaling excluding CSI part 2 is transmitted and CSI part 2 is not transmitted, where Δ is a parameter greater than 0.

[0020] Optionally, when calculating the PUCCH transmission power adjustment parameters used to determine the PUCCH transmission power, the PUCCH transmission power adjustment parameters are calculated based on the second type of control signaling excluding CSI part 2 and CSI part 2 respectively, and then the maximum or minimum value is taken to further determine the PUCCH transmission power.

[0021] Optionally, when second-class control signaling and / or data with different priority indices are multiplexed, the priorities of different channels are sorted, and then power is allocated according to the priority sorting.

[0022] Optionally, the priorities are ordered from high to low as follows: Physical uplink shared channel (PUSCH) containing HARQ-ACK with a first priority index, or PUCCH containing HARQ-ACK, SR, or LRR with a first priority index, wherein the PUSCH is either a PUSCH with a second priority index or a PUSCH with a first priority index, and the PUCCH is either a PUCCH with a second priority index or a PUCCH with a first priority index; PUSCH transmission containing CSI with a first priority index, or PUCCH transmission containing CSI with a first priority index, wherein the PUSCH is either a PUSCH with a second priority index or a PUSCH with a first priority index, and the PUCCH is either a PUCCH with a second priority index or a PUCCH with a first priority index; and PUSCH transmission with a first priority index that does not contain HARQ-ACK or CSI with a first priority index.

[0035] 3GPP defines three main directions for 5G application scenarios: enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). eMBB refers to further improvements in user experience and performance based on existing mobile broadband services, primarily pursuing the ultimate communication experience between people. mMTC and URLLC are IoT application scenarios, but with different focuses: mMTC mainly addresses information interaction between people and things, while URLLC primarily addresses communication needs between things. 5G's eMBB and URLLC will adopt a joint networking approach, supporting both URLLC and eMBB services within the same cell. Since URLLC services may be sparse, joint eMBB and URLLC networking can improve system spectrum efficiency compared to URLLC networking alone. When URLLC services are present in the system, they are prioritized; when there are no URLLC services or URLLC services consume minimal resources, eMBB services can be scheduled. Currently, when URLLC and eMBB services conflict, data and / or control information from the URLLC service are transmitted first, which results in a loss of performance for the eMBB service. Therefore, it is urgent to find a solution to optimize the transmission of data and control information for the eMBB service.

[0036] In the following, various embodiments of this application will be described in detail with reference to the accompanying drawings.

[0037] Figure 1 A block diagram of a second type of transceiver node according to an embodiment of the present invention is shown.

[0038] refer to Figure 1 The second type of transceiver node 100 may include a transceiver 101 and a controller 102.

[0039] Transceiver 101 can be configured to receive first type data and / or first type control signaling from a first type transceiver node and to send second type data and / or second type control signaling to the first type transceiver node within a defined time period.

[0040] The controller 102 may be an application-specific integrated circuit (ASIC) or at least one processor. The controller 102 may be configured to control the overall operation of the second type of transceiver node, and to control the second type of transceiver node to implement the methods proposed in this invention. Specifically, the controller 102 may be configured to determine, based on the first type of data and / or the first type of control signaling, the second type of data and / or the second type of control signaling, the time unit for transmitting the second type of data and / or the second type of control signaling, and the power for transmitting the second type of data and / or the second type of control signaling, and to control the transceiver 101 to transmit the second type of data and / or the second type of control signaling to the first type of transceiver node within the determined time unit.

[0041] In some implementations, the first type of data can be data sent from a first type of transceiver node to a second type of transceiver node. In the following example, downlink data carried via PDSCH (Physical Downlink Shared Channel) is used as an example (but not limited to) to illustrate the first type of data.

[0042] In some implementations, the second type of data can be data sent from a second type of transceiver node to a first type of transceiver node. The following example uses uplink data carried by a PUSCH (Physical Uplink Shared Channel) as an example (but is not limited to) to illustrate the second type of data.

[0043] In some implementations, the first type of control signaling can be control signaling sent from a first type of transceiver node to a second type of transceiver node. In the following examples, downlink control signaling is used as an example (but not limited to) to illustrate the first type of control signaling. Downlink control signaling can be DCI (Downlink control information) carried through the PDCCH (Physical Downlink Control Channel) and / or control signaling carried through the PDSCH (Physical Downlink Shared Channel).

[0044] In some implementations, the second type of control signaling can be control signaling sent from a second type of transceiver node to a first type of transceiver node. In the following examples, uplink control signaling is used as an example (but not limited to) to illustrate the second type of control signaling. Uplink control signaling can be UCI (Uplink Control Information) carried through PUCCH (Physical Uplink Control Channel) and / or control signaling carried through PUSCH (Physical Uplink Shared Channel). The type of UCI can include...

[0045] HARQ-ACK information, SR (Scheduling Request), LRR (Link Recovery Request), and CSI (Channel State Information).

[0046] In some implementations, the first type of time unit is the time unit for the first type of transceiver node to send the first type of data and / or the first type of control signaling. In the following examples, the downstream time unit is used as an example (but not limited to) to illustrate the first type of time unit.

[0047] In some implementations, the second type of time unit is the time unit for the second type of transceiver node to send the second type of data and / or the second type of control signaling. In the following examples, the uplink time unit is used as an example (but not limited to) to illustrate the second type of time unit.

[0048] In some implementations, the first type of time unit and the second type of time unit can be one or more time slots, one or more sub-slots, one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols, or one or more subframes.

[0049] Depending on the network type, the term "base station" or "BS" can refer to any component (or set of components) configured to provide radio access to a network, such as a transmitting point (TP), a transmitting-receiving point (TRP), an enhanced base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femtocell, a WiFi access point (AP), or other wirelessly enabled devices. Base stations can operate according to one or more wireless communication protocols—for example, 5G 3GPP New Radio Interface / Access (NR), Long Term Evolution (LTE), Advanced LTE (LTE-A), High Speed ​​Packet Access (HSPA), Wi-Fi...

[0050] 802.11a / b / g / n / ac, etc., are used to provide wireless access. For convenience, the terms "BS" and "TRP" are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. Furthermore, depending on the network type, the terms "User Equipment" or "UE" may refer to any of the following components: "mobile station," "subscriber station," "remote terminal," "wireless terminal," "receiving point," "user equipment," or simply "terminal." For convenience, the terms "User Equipment" or "UE" are used in this patent document to refer to a remote wireless device wirelessly accessing the BS, whether the UE is a mobile device (such as a mobile phone or smartphone) or a fixed device as commonly considered (e.g., a desktop computer or vending machine).

[0051] Figure 2 A flowchart of a method executed by a UE according to an embodiment of the present invention is shown.

[0052] First, in step 201, the UE receives downlink data and / or downlink control signaling from the base station.

[0053] In step 202, the UE determines uplink data and / or uplink control signaling, uplink time units for transmitting uplink data and / or uplink control signaling, uplink physical channels, and power for transmitting second type data and / or second type control signaling based on downlink data and / or downlink control signaling.

[0054] In step 203, within a determined uplink time unit, the UE transmits uplink data and / or uplink control signaling to the base station at a determined power for transmitting type II data and / or type II control signaling.

[0055] In some implementations, the UE can be configured with two priority levels for uplink transmission. For example, the two priority levels can include a first priority and a second priority that are different from each other. In one example, the first priority may be higher than the second priority. However, embodiments of this disclosure are not limited to this; for example, the UE can be configured with more than two priority levels. For convenience, embodiments of this disclosure are described with the first priority being higher than the second priority.

[0056] In one example, two levels of priority can be indicated by a priority number or priority index (e.g., priority index 1 and priority index 0). For example, a larger priority index can correspond to a higher priority; that is, priority index 1 can correspond to a higher priority than priority index 0. In this case, the larger priority index (e.g., priority index 1) can be a higher priority (e.g., first priority), and the smaller priority index (e.g., priority index 0) can be a lower priority (e.g., second priority). However, embodiments of this disclosure are not limited to this; for example, other priority indices or indicators can be used to indicate two levels of priority. For convenience, embodiments of this disclosure are described in terms of a higher priority corresponding to a larger priority index (e.g., priority index 1) than to a smaller priority index (e.g., priority index 0). The invention is not limited to the above-described manner; for example, in embodiments of this disclosure, priority index 1 can be used interchangeably with first priority, a larger priority index, or a higher priority, and priority index 0 can be used interchangeably with second priority, a smaller priority index, or a lower priority.

[0057] In some implementations, the two priority levels configured for the UE can be two physical layer priority levels. For example, one of the two priority levels (a first priority (e.g., priority index 1) or a second priority (e.g., priority index 0)) can be provided for PUSCH or PUCCH. Specifically, a PUSCH or PUCCH transmission (including duplicate transmissions if any) can have (e.g., corresponding to) priority index 0 or a higher priority index (e.g., priority index 1).

[0058] In one example, for a scheduling-free PUSCH transmission, the UE can determine the priority index based on the priority parameter (if configured). For a PUCCH transmission with HARQ-ACK information corresponding to an SPS (Semi-Persistent Scheduling) PDSCH receive or an SPS PDSCH release, the UE can determine the priority index of the PUCCH transmission from the HARQ-CodebookID parameter (if configured). If no HARQ-ACK is provided for a particular UE...

[0059] If a priority index is configured for a PUSCH or PUCCH transmission, then the priority index for that PUSCH or PUCCH transmission can be 0.

[0060] In one example, if the UE listens to the PDCCH in an active DL BWP to detect DCI format 0_1 ​​and DCI format 1_1, or detects DCI format 0_2 and DCI format 1_2, a priority index can be provided through the priority indication field. If the UE indicates that it is capable of listening to the PDCCH in an active DL BWP to detect DCI format 0_1 ​​and DCI format 1_1, and detecting DCI format 0_2 and DCI format 1_2, then DCI format 0_1 ​​or DCI format 0_2 can schedule PUSCH transmissions of any priority, and DCI format 1_1 or DCI format 1_2 can schedule PDSCH reception and trigger PUCCH transmissions with corresponding HARQ-ACK information of any priority.

[0061] In one example, the UE can be configured with a PUCCH configuration list, which can contain two PUCCH configurations: a first PUCCH configuration and a second PUCCH configuration. For example, the first PUCCH configuration can correspond to a second priority (e.g., a lower priority index (e.g., priority index 0)), meaning the priority of the first PUCCH configuration can be the second priority (e.g., a lower priority index (e.g., priority index 0)). Similarly, the second PUCCH configuration can correspond to a first priority (e.g., a higher priority index (e.g., priority index 1)), and the priority of the second PUCCH configuration can be the first priority (e.g., a higher priority index (e.g., priority index 1)).

[0062] For example, the sub-slot configuration length of each PUCCH configuration in the first and second PUCCH configurations can be 7 OFDM symbols or 2 OFDM symbols. Different

[0063] The sub-slot configuration length of the PUCCH configuration can be configured separately.

[0064] In some implementations, the UE can be configured with a pdsch-HARQ-ACK-Codebook list. For example, this pdsch-HARQ-ACK-Codebook list may contain two pdsch-HARQ-ACK-Codebook configurations, corresponding to a first HARQ-ACK codebook and a second HARQ-ACK codebook, respectively. For example, the first HARQ-ACK codebook may be associated with a PUCCH of a lower priority index (e.g., priority index 0), and the second HARQ-ACK codebook may be associated with a PUCCH of a higher priority index (e.g., priority index 1). In this case, the priority of the first HARQ-ACK codebook may be the second priority (e.g., a lower priority index (e.g., priority index 0)), and the priority of the second HARQ-ACK codebook may be the first priority (e.g., a higher priority index (e.g., priority index 1)).

[0065] In some implementations, a first priority or higher priority (e.g., a larger priority index (e.g., priority index 1)) may correspond to a first service (e.g., URLLC service), and a second priority or lower priority (e.g., a smaller priority index (e.g., priority index 0)) may correspond to a second service (e.g., eMBB service).

[0066] According to one embodiment of the present invention, UCIs of different priority indices are multiplexed in the same...

[0067] For PUCCH transmission, determining the PUCCH transmission power is a problem that needs to be solved.

[0068] In this embodiment, UCIs with different priority indices can use different code rates, or UCIs with different priority indices can use the same code rate and uniform encoding.

[0069] If the UE uses an active uplink BWPb on carrier f of the primary serving cell c

[0070] PUCCH transmission uses PUCCH power control to adjust state number l, and the UE determines the PUCCH transmission power P at PUCCH transmission time i. PUCCH,b,f,c (i,q u ,q d ,l) is

[0074] P O_PUCCH,b,f,c (q u This refers to the open-loop power parameter. For example, it can be determined using the method specified in 3GPP TS38.213.

[0075] The transmission bandwidth of the PUCCH at time i on an active uplink BWPb on carrier f of the primary serving cell c is expressed in RB. It should be noted that the subcarrier spacing of BWPb is μ.

Through parameter configuration, scheduling flexibility can be increased, allowing for the transmission of lower-priority UCIs as much as possible while ensuring the reliability of high-priority UCI transmission.

[0175] According to one embodiment of the present invention, in the case of a single cell, dual uplink carriers, or uplink CA (Carrier Aggregation), the sum of the powers calculated individually by the UE on each carrier and uplink cell may exceed the UE's total configured transmission power. In this case, the UE must prioritize the allocation of high-priority transmissions and reduce the power of low-priority transmissions to ensure that the sum of the powers does not exceed the total configured transmission power. How to prioritize different channels when using UCIs and / or data multiplexing with different priority indices is a problem that needs to be solved.

[0176] This embodiment uses a priority index with two levels as an example to illustrate the rules for sorting the priorities of different channels. This embodiment can also be used in scenarios with more than two priority indices.

[0177] A UE can be configured with a PUCCH configuration list, which can contain two PUCCH configurations. The first PUCCH configuration can have a lower priority index (e.g., priority index 0). The second PUCCH configuration can have a higher priority index (e.g., priority index 1).

[0178] The power allocated by the UE to PUSCH / PUCCH / PRACH (Physical Random Access Channel) / SRS (Sounding Reference Signal) transmissions is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power.

It should be noted that a PUSCH can be a PUSCH with a lower priority index (e.g., priority index 0) or a PUSCH with a higher priority index (e.g., priority index 1).

[0181] PUCCH can be a PUCCH with a smaller priority index (e.g., priority index 0) or a PUCCH with a larger priority index (e.g., priority index 1).

[0182] - A PUSCH transport containing a CSI with a larger priority index (e.g., priority index 1) or a PUCCH transport containing a CSI with a larger priority index (e.g., priority index 1). It should be noted that a PUSCH can be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1), and a PUCCH can be a PUCCH with a smaller priority index (e.g., priority index 0) or a PUCCH with a larger priority index (e.g., priority index 1).

[0183] - A PUSCH transmission that does not contain a HARQ-ACK message or CSI with a larger priority index (e.g., priority index 1). Optionally, the PUSCH can further differentiate priorities based on whether it contains a HARQ-ACK message or CSI with a smaller priority index (e.g., priority index 0). For example, a HARQ-ACK message or CSI with a smaller priority index (e.g., priority index 0)...

[0184] A PUSCH transmission with a larger priority index (e.g., priority index 1) for the ACK message and / or CSI has a higher priority than a PUSCH transmission without a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI (e.g., priority index 1). Alternatively, a PUSCH transmission with a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI (e.g., priority index 1) has a lower priority than a PUSCH transmission without a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI (e.g., priority index 1). Optionally, for a Type-2 random access procedure, a PUSCH transmission with a larger priority index (e.g., priority index 1) on the primary serving cell has the same priority as a PUSCH transmission without a larger priority index (e.g., priority index 1) for the HARQ-ACK message or CSI (e.g., priority index 1). Alternatively, for a Type-2 random access procedure, a PUSCH transmission with a higher priority index (e.g., priority index 1) on the primary serving cell has the same priority as a PUSCH transmission that does not contain a HARQ-ACK message with a higher priority index (e.g., priority index 1) or a CSI that contains a HARQ-ACK message with a lower priority index (e.g., priority index 0) and / or a PUSCH transmission with a higher priority index (e.g., priority index 1) on the CSI.

[0185] - HARQ-ACK messages that do not contain a higher priority index (e.g., priority index 1) or PUSCH transmissions with a lower priority index (e.g., priority index 0) for CSI, and / or HARQ-ACK messages that do not contain a higher priority index (e.g., priority index 1).

[0186] PUCCH transmission of ACK information or CSI or SR or LLR with a lower priority index (e.g., priority index 0).

[0187] - HARQ-ACK information containing a smaller priority index (e.g., priority index 0), and / or SR, and / or LRR containing a smaller priority index (e.g., priority index 0).

[0188] A PUCCH transmission with a lower priority index (e.g., priority index 0) or a PUSCH transmission with a lower priority index (e.g., priority index 0) that contains HARQ-ACK information with a lower priority index (e.g., priority index 0).

[0189] - PUCCH transports with a smaller priority index (e.g., priority index 0) in a CSI, and / or PUSCH transports with a smaller priority index (e.g., priority index 0) in a CSI.

[0190] - PUSCH transmissions that do not contain HARQ-ACK information or CSI with a lower priority index (e.g., priority index 0) for Type-2 random access procedures, where the lower priority index is on the primary serving cell.

[0191] PUSCH transfer (e.g., priority index 0).

[0192] -SRS transmission (aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS),

[0193] Alternatively, PRACH can be transmitted on a serving cell other than PCell.

[0194] It should be noted that, under the same priority order, and for carrier aggregation operations, the UE prioritizes power allocation for transmissions on the primary serving cell of the MCG (Master Cell group) or SCG (Secondary Cell group), rather than transmissions on the secondary serving cell. Under the same priority order, and for operations using two UL carriers, the UE prioritizes power allocation for transmissions on the carrier in which the UE is configured to transmit the PUCCH. If the PUCCH is not configured for either of the two UL carriers, the UE prioritizes power allocation for transmissions on the non-supplementary UL carrier.

[0195] This method specifies the priority order of power allocation for different channels during uplink power control, prioritizing the transmission power of high-priority services and thus improving the reliability of high-priority services.

[0196] It should be noted that the power control method for multiple UCIs with different priorities multiplexed onto a PUCCH in the embodiments of this disclosure is also applicable to scenarios where the priority indices of the multiple UCIs are the same but the types of the multiple UCIs are different, and also applicable to scenarios where the priority indices of the multiple UCIs are different and the UCI types of the multiple UCIs are also different.

[0197] It should be noted that the power control method for multiplexing multiple UCIs of different priorities onto a single PUCCH in the embodiments of this disclosure can also be applied to the multiplexing of unicast UCIs and groupcast / multicast UCIs. For example, the UCI with a larger priority index (e.g., HARQ-ACK) in the embodiments of this disclosure can be replaced with a multicast / broadcast UCI, and the UCI with a smaller priority index (e.g., HARQ-ACK) in the embodiments of this disclosure can be replaced with a unicast UCI. Alternatively, the UCI with a smaller priority index (e.g., HARQ-ACK) in the embodiments of this disclosure can be replaced with a multicast / broadcast UCI, and the UCI with a larger priority index (e.g., HARQ-ACK) in the embodiments of this disclosure can be replaced with a unicast UCI.

[0198] In the embodiments of this disclosure, unicast can refer to a communication method between a network and a UE, while multicast / broadcast can refer to a communication method between a network and multiple UEs. For example, a unicast PDSCH can be a single PDSCH received by a UE, and the scrambling of the PDSCH can be based on a UE-specific Radio Network Temporary Indicator (RNTI), such as C-RNTI. A multicast / broadcast PDSCH can be a PDSCH received simultaneously by more than one UE, and the scrambling of the PDSCH can be based on a common RNTI shared by the UE groups, such as Multicast / Broadcast Services (MBS)-RNTI. The unicast UCI can include the HARQ-ACK information, SR, or CSI of the unicast PDSCH. The multicast / broadcast UCI can include the HARQ-ACK information of the multicast / broadcast PDSCH.

[0199] According to one embodiment of the present invention, in the case of a single cell, dual uplink carriers, or uplink CA (Carrier Aggregation), the sum of the powers calculated individually by the UE on each carrier and uplink cell may exceed the UE's total configured transmission power. In this case, the UE must prioritize the allocation of high-priority transmissions and reduce the power of low-priority transmissions to ensure that the sum of the powers does not exceed the total configured transmission power. How to prioritize different channels when using UCIs and / or data multiplexing with different priority indices is a problem that needs to be solved.

[0200] This embodiment uses a priority index with two levels as an example to illustrate the rules for sorting the priorities of different channels. This embodiment can also be used in scenarios with more than two priority indices.

[0201] A UE can be configured with a PUCCH configuration list, which can contain two PUCCH configurations. The first PUCCH configuration can have a lower priority index (e.g., priority index 0). The second PUCCH configuration can have a higher priority index (e.g., priority index 1).

[0202] The UE does not support multiplexing a UCI with a larger priority index onto a PUCCH with a smaller priority index for transmission.

[0203] The power allocation of the UE to PUSCH / PUCCH / PRACH (Physical Random Access Channel) / SRS (Sounding Reference Signal) is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power.

[0204] - PRACH transmission on the primary serving cell.

[0205] - A PUSCH transmission containing HARQ-ACK information with a larger priority index (e.g., priority index 1), or a PUSCH transmission containing HARQ-ACK information with a larger priority index (e.g., priority index 1), and / or SR, and / or LRR with a larger priority index (e.g., priority index 1). It should be noted that a PUSCH can be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1).

[0206] - PUSCH transfers that include a CSI with a larger priority index (e.g., priority index 1). It should be noted that a PUSCH can be a PUSCH with a smaller priority index (e.g., priority index 0) or a PUSCH with a larger priority index (e.g., priority index 1).

[0207] - A PUSCH transmission that does not contain a HARQ-ACK message or CSI with a larger priority index (e.g., priority index 1). Optionally, the PUSCH can further differentiate priorities based on whether it contains a HARQ-ACK message or CSI with a smaller priority index (e.g., priority index 0). For example, a HARQ-ACK message or CSI with a smaller priority index (e.g., priority index 0)...

[0208] A PUSCH transmission with a larger priority index (e.g., priority index 1) for the ACK message and / or CSI has a higher priority than a PUSCH transmission without a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI. Alternatively, a PUSCH transmission with a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI has a higher priority index (e.g., priority index 1) has a lower priority than a PUSCH transmission without a smaller priority index (e.g., priority index 0) for the HARQ-ACK message and / or CSI. Optionally, for a Type-2 random access procedure, a PUSCH with a larger priority index (e.g., priority index 1) on the primary serving cell is preferred over a PUSCH transmission with a larger priority index (e.g., priority index 1) for the HARQ-ACK message and / or CSI.

[0209] 1) The PUSCH priorities are the same. Alternatively, for a Type-2 random access procedure, a PUSCH with a larger priority index (e.g., priority index 1) on the primary serving cell is paired with a HARQ-ACK message that does not contain a larger priority index (e.g., priority index 1) or a CSI that contains a smaller priority index (e.g., priority index 0) and a HARQ-ACK message that does not contain a larger priority index (e.g., priority index 1).

[0210] PUSCH of information and / or CSI with a larger priority index (e.g., priority index 1)

[0211] The priorities are the same. Alternatively, for a Type-2 random access procedure, a PUSCH with a larger priority index (e.g., priority index 1) on the primary serving cell has the same priority as a PUSCH with a larger priority index (e.g., priority index 1) that does not contain a larger priority index (e.g., priority index 1) of HARQ-ACK or CSI and does not contain a smaller priority index (e.g., priority index 0) of HARQ-ACK and / or CSI.

[0212] - PUSCH transmissions that do not contain HARQ-ACK messages with a larger priority index (e.g., priority index 1) or PUCCH transmissions with a smaller priority index (e.g., priority index 0) of the CSI, and / or PUCCH transmissions with a smaller priority index (e.g., priority index 0).

[0213] - HARQ-ACK information containing a smaller priority index (e.g., priority index 0), and / or SR, and / or LRR PUCCH transmissions containing a smaller priority index (e.g., priority index 0), and / or PUSCH transmissions containing a smaller priority index (e.g., priority index 0) HARQ-ACK information containing a smaller priority index (e.g., priority index 0).

[0214] - PUCCH transports with a smaller priority index (e.g., priority index 0) in a CSI, and / or PUSCH transports with a smaller priority index (e.g., priority index 0) in a CSI.

[0215] - PUSCH transmissions that do not contain HARQ-ACK information or CSI with a lower priority index (e.g., priority index 0), for Type-2 random access procedures, PUSCH transmissions with a lower priority index (e.g., priority index 0) on the primary serving cell.

[0216] - SRS transmission (aperiodic SRS has higher priority than semi-persistent and / or periodic SRS), or PRACH transmission on the serving cell outside the PCell.

[0217] It should be noted that, under the same priority order, and for carrier aggregation operations, the UE prioritizes power allocation for transmissions on the primary serving cell of the MCG (Master Cell group) or SCG (Secondary Cell group), rather than transmissions on the secondary serving cell. Under the same priority order, and for operations using two UL carriers, the UE prioritizes power allocation for transmissions on the carrier in which the UE is configured to transmit the PUCCH. If the PUCCH is not configured for either of the two UL carriers, the UE prioritizes power allocation for transmissions on the non-supplementary UL carrier.

[0218] This method specifies the priority ordering of power allocation for different channels during uplink power control, prioritizing the transmission power of high-priority services to improve their reliability. According to one embodiment of the invention, in a single-cell, dual-uplink-carrier, or uplink CA (Carrier Aggregation) scenario, the sum of the powers calculated individually by the UE on each carrier and uplink cell may exceed the UE's total configured transmission power. In this case, the UE must allocate power to high-priority transmissions according to their transmission priorities and reduce the power of low-priority transmissions to ensure that the sum of the powers does not exceed the total configured transmission power. How to prioritize different channels during UCI and / or data multiplexing with different priority indices is a problem that needs to be solved.

[0219] This embodiment uses a priority index with two levels as an example to illustrate the rules for sorting the priorities of different channels. This embodiment can also be used in scenarios with more than two priority indices.

[0220] A UE can be configured with a PUCCH configuration list, which can contain two PUCCH configurations. The first PUCCH configuration can have a lower priority index (e.g., priority index 0). The second PUCCH configuration can have a higher priority index (e.g., priority index 1).

[0221] UE does not support reusing UCI and / or data indexed by different priorities.

[0222] The power allocation of the UE to PUSCH / PUCCH / PRACH (Physical Random Access Channel) / SRS (Sounding Reference Signal) is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power.

[0223] - PRACH transmission on the primary serving cell.

[0224] - PUSCH and / or PUCCH transmissions with a higher priority index (e.g., priority index 1).

[0225] - PUSCH and / or PUCCH transport with a smaller priority index (e.g., priority index 0).

[0226] - For PUCCH and / or PUSCH transmissions with the same priority index

[0227] - PUCCH transmissions containing HARQ-ACK information, and / or SR, and / or LRR, or PUSCH transmissions containing HARQ-ACK information.

[0228] - PUCCH transmissions containing CSI or PUSCH transmissions containing CSI.

[0229] - PUSCH transmissions that do not contain HARQ-ACK information or CSI, and PUSCH transmissions on the primary serving cell for Type-2 random access procedures.

[0230] -SRS transmission (aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS),

[0231] Alternatively, PRACH can be transmitted on a serving cell other than PCell.

[0232] It should be noted that, under the same priority order, and for carrier aggregation operations, the UE prioritizes power allocation for transmissions on the primary serving cell of the MCG (Master Cell group) or SCG (Secondary Cell group), rather than transmissions on the secondary serving cell. Under the same priority order, and for operations using two UL carriers, the UE prioritizes power allocation for transmissions on the carrier in which the UE is configured to transmit the PUCCH. If the PUCCH is not configured for either of the two UL carriers, the UE prioritizes power allocation for transmissions on the non-supplementary UL carrier.

[0233] This method specifies the priority order of power allocation for different channels during uplink power control, prioritizing the transmission power of high-priority services to improve their reliability. It clarifies that the priority of the priority index channel is higher than that of the low-priority index channel, thus clarifying UE behavior and improving uplink transmission reliability. For uplink channels of the same priority, if the UE supports simultaneous PUCCH / PUSCH transmission, this method determines the priority order when PUCCH and PUSCH are present simultaneously, clarifying UE behavior and improving uplink transmission reliability.

[0234] According to one embodiment of the present invention, when allocating power to PUCCH and / or PUSCH, at least one of the following rules may be followed to ensure that the total power is less than or equal to the maximum transmit power.

[0235] Rule 1: PUSCH transmissions with a higher priority index (e.g., priority index 1) that include HARQ-ACK information with a higher priority index (e.g., priority index 1), or PUCCH transmissions with a higher priority index (e.g., priority index 1) that include HARQ-ACK information with a higher priority index (e.g., priority index 1) and / or SR, and / or LRR, have a higher priority index (e.g., priority index 1) than other transmissions except for PRACH transmissions on the primary serving cell.

[0236] PUCCH / PUSCH transmission.

[0237] Rule 2: PUSCH transmissions that contain HARQ-ACK information with a larger priority index (e.g., priority index 1), or PUCCH transmissions that contain HARQ-ACK information with a larger priority index (e.g., priority index 1) and / or SR, and / or LRR with a larger priority index (e.g., priority index 1), have a higher priority than other PUCCH / PUSCH transmissions except for PRACH transmissions on the primary serving cell.

[0238] Rule 3: A PUSCH transmission with a larger priority index (e.g., priority index 1) that contains HARQ-ACK information with a larger priority index (e.g., priority index 1), or a PUSCH transmission with a larger priority index (e.g., priority index 1) that contains HARQ-ACK information with a larger priority index (e.g., priority index 1), and / or an SR, and / or LRR, has a higher priority than a PUSCH transmission with a smaller priority index (e.g., priority index 0) that contains HARQ-ACK information with a larger priority index (e.g., priority index 1).

[0239] Rule 4: The priority index of PUSCH can be determined based on the highest priority index among the data and control information in PUSCH.

[0240] Rule 5: The priority index of PUCCH can be determined based on the highest priority index of the control information in PUCCH.

[0241] Rule 6: A PUSCH transmission that contains a larger priority index of CSI (e.g., priority index 1) has a higher (or lower) priority than a PUSCH transmission that contains a smaller priority index of HARQ-ACK information (e.g., priority index 0) that contains a larger priority index of HARQ-ACK information (e.g., priority index 1).

[0242] Rule 7: A PUSCH transmission with a smaller priority index (e.g., priority index 0) that contains HARQ-ACK information with a larger priority index (e.g., priority index 1) has a higher (or lower) priority than a PUSCH transmission with a larger priority index (e.g., priority index 1) that does not contain HARQ-ACK or CSI.

[0243] For example, the power allocation for PUSCH / PUCCH / PRACH / SRS transmissions by the UE is ordered from high to low in the following order to ensure that the total power is less than or equal to the maximum transmit power:

[0244] - PRACH transmission on the primary serving cell.

[0245] - PUSCH and / or PUCCH and / or UCI transmissions with a higher priority index (e.g., priority index 1). It should be noted that the priority index of PUSCH can be determined based on...

[0246] The priority index of a PUSCH is determined by the highest priority index among the data and control information. For example, a PUSCH with a smaller priority index (e.g., priority index 0) that contains a HARQ-ACK message with a larger priority index (e.g., priority index 1) is considered to have a larger priority index. The priority index of a PUCCH can be determined based on the highest priority index among the control information in the PUCCH.

[0247] - Optionally, PUSCH and / or a smaller priority index (e.g., priority index 0)

[0248] PUCCH transmission.

[0249] - Wherein, for PUCCH and / or PUSCH transmissions with the same priority index, the following order applies.

[0250] Sort by order from highest to lowest:

[0251] - PUCCH transmissions containing HARQ-ACK information, and / or SR, and / or LRR, and /

[0252] Or a PUSCH transmission containing HARQ-ACK information.

[0253] Optionally, PUCCH transmissions containing HARQ-ACK information with higher priority indices and / or

[0254] A PUSCH transmission that contains HARQ-ACK information with a higher priority index has a higher priority than a PUSCH transmission that only contains HARQ-ACK information with a lower priority index.

[0255] - PUCCH transmissions containing CSI and / or PUSCH transmissions containing CSI.

[0256] - PUSCH transmissions that do not contain HARQ-ACK information or CSI, and PUSCH transmissions on the primary serving cell for Type-2 random access procedures.

[0257] -SRS transmission (aperiodic SRS has a higher priority than semi-persistent and / or periodic SRS),

[0258] Alternatively, PRACH can be transmitted on a serving cell other than the primary serving cell (PCell).

[0259] This method specifies the priority order of power allocation for different channels during uplink power control, prioritizing the transmission power of high-priority services to improve their reliability. It clarifies that the priority of the priority index channel is higher than that of the low-priority index channel, thus clarifying the UE's behavior and improving uplink transmission reliability.
