Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, apparatus, and storage medium for determining resources for UCI multiplexing. Background Art

[0002] In the NR Rel-17 phase, multiplexed transmission of uplink control information (UCI) with different physical layer priorities is supported. It may support independent encoding and mapping of UCI with different priorities on the same physical uplink control channel (PUCCH) resource. However, there is no specific PUCCH resource determination scheme in the prior art.

[0003] In the prior art, when determining the PUCCH resource used for multiplexed UCI, only the total number of bits of the multiplexed UCI and a transmission code rate are used to determine the number of resource blocks (RBs) actually used for transmission. Since the target code rates corresponding to different UCI are different, in order to ensure the transmission performance of all UCI, the multiplexed UCI may be transmitted using a relatively conservative low code rate, occupying too many resources and affecting the system transmission efficiency.

[0060] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0061] The technical solutions provided by the embodiments of the present application can be applied to multiple systems, especially 5G systems. For example, the applicable systems can be Global System of Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems, etc. Both terminal devices and network devices are included in these multiple systems. The system may also include a core network part, such as an Evolved Packet System (EPS), a 5G System (5GS), etc.

[0062] The terminal device involved in the embodiments of this application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges language and / or data with the wireless access network. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, which is not limited in the embodiments of this application.

[0063] The network device involved in the embodiments of this application can be a base station, which can include multiple cells that provide services to terminals. Depending on the specific application scenarios, the base station can also be referred to as an access point, or it can be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or other names. The network device can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network can include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of this application can be a network device (Base Transceiver Station, BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or it can be a network device (NodeB) in a Wide-band Code Division Multiple Access (WCDMA), or it can also be an evolved network device (evolutional Node B, eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), or it can be a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc. The embodiments of this application do not limit this. In some network architectures, the network device can include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit can also be arranged separately geographically.

[0064] In a New Radio (NR) communication system, usually the base station configures one or more sets of Physical Uplink Control Channel (PUCCH) resources for the terminal to transmit Hybrid Automatic Repeat reQuest (HARQ) Acknowledgement (ACK) through dedicated Radio Resource Control (RRC) configuration information. When configuring multiple sets of PUCCH resources, one set of PUCCH resources needs to be selected according to the number of transmission bits of HARQ-ACK, and it is determined which PUCCH resource in the selected set of PUCCH resources is used to transmit HARQ-ACK through the Resource Indicator field ARI in the Downlink Control Information (DCI) corresponding to HARQ-ACK. According to the determined PUCCH, transmission is performed according to the transmission scheme of the corresponding PUCCH format.

[0065] If there is only Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission in the set of downlink transmission positions corresponding to a feedback position, the dedicated PUCCH format 0 or 1 resources configured by higher layer signaling are used to transmit 1-bit HARQ-ACK. When HARQ-ACK is transmitted using PUCCH format 2 or 3, if the corresponding PUCCH resource contains more than 1 resource block (RB), RBmin RBs not exceeding the number of RBs contained in the PUCCH are determined based on the number of resource elements (REs) contained in the PUCCH, the configured transmission code rate, and the number of transmission bits of HARQ-ACK, and used as the number of RBs for actually transmitting HARQ-ACK.

[0066] When HARQ-ACK and uplink scheduling request (SR) are multiplexed for transmission, or when HARQ-ACK, SR (if any), and channel state information (CSI) are multiplexed for transmission, if HARQ-ACK is transmitted using PUCCH format 2 or 3 or 4, the UCI is multiplexed on the HARQ-ACK resource for transmission. A set of PUCCH resources is selected based on the total number of bits of the multiplexed UCI for transmission, and which PUCCH resource in the selected set of PUCCH resources is used to transmit the multiplexed UCI is determined based on the ARI indication in the DL DCI corresponding to the HARQ-ACK. When the selected PUCCH resource is transmitted using PUCCH format 2 or 3, if the corresponding PUCCH resource contains more than 1 RB, the number of RBmin RBs not exceeding the number of RBs contained in the PUCCH is determined based on the number of REs contained in the PUCCH, the configured transmission code rate, and the total number of bits of the multiplexed UCI, and is used as the number of RBs actually used to transmit the multiplexed UCI.

[0067] The prior art does not support multiplexing UCIs with different priorities on one PUCCH resource for transmission, and for the multiplexing of UCIs with the same priority, the number of RBs actually used on the PUCCH resource is determined only based on one code rate and the total number of bits of the UCI. For the multiplexing of UCIs with different priorities, an independent coding scheme may be adopted. If the number of RBs actually used is still determined based on one code rate and the total number of bits of the UCI, it may lead to an unnecessary increase in resource overhead and reduce the system transmission performance.

[0068] Regarding the multiplexed transmission of UCIs with different priorities that will be supported in 5G NR in the Rel-17 phase, when the UCIs with different priorities are multiplexed on one PUCCH resource for transmission, there is no specific PUCCH resource determination scheme in the prior art.

[0069] Among them, the method and the apparatus are based on the same inventive concept. Since the principles of the method and the apparatus for solving problems are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be elaborated.

[0070] Figure 1 It is a schematic flow diagram of the resource determination method for UCI multiplexing provided by the embodiments of this application. As Figure 1 shown, the method includes the following steps:

[0071] Step 100, for multiple independently coded UCIs multiplexed on the same uplink channel resource, determine the number of resource blocks RB actually used based on the number of bits and the code rate respectively corresponding to the multiple independently coded UCIs.

[0072] Specifically, in the method provided by the embodiments of the present application, the uplink channel may be a PUCCH or other uplink channels, and the uplink channel resources may be PUCCH resources or other channel resources. For multiple independently encoded UCIs multiplexed and transmitted on the same PUCCH resource, the number of RBs actually used is determined based on the number of bits and code rates corresponding to the multiple independently encoded UCIs.

[0073] Multiple UCIs can be independently encoded and multiplexed on the same PUCCH resource for transmission. During the transmission process, the number of RBs actually occupied can be determined based on the number of bits and code rates corresponding to the multiple independently encoded UCIs.

[0074] Taking two independently encoded first UCI and second UCI as an example. Among them, the first UCI includes high-priority HARQ-ACK and / or high-priority SR, and the second UCI includes low-priority HARQ-ACK and / or low-priority SR and / or low-priority CSI, that is, the first UCI and the second UCI can be respectively the independently encoded physical layer high-priority HARQ-ACK (and high-priority SR), and low-priority HARQ-ACK and / or low-priority SR and / or low-priority CSI multiplexed and transmitted on the same PUCCH resource.

[0075] Alternatively, the first UCI includes unicast HARQ-ACK, and the second UCI includes multicast HARQ-ACK, that is, the first UCI and the second UCI can be respectively the independently encoded unicast HARQ-ACK and multicast HARQ-ACK multiplexed and transmitted on the same PUCCH resource. In addition to the unicast HARQ-ACK included in the first UCI, it does not exclude that other unicast UCI information may also be included, such as unicast SR, unicast CSI, etc.

[0076] The resource determination method for UCI multiplexing provided by the embodiments of the present application can use different code rates and UCI bit numbers for different-priority UCIs to respectively determine the corresponding resources, so as to determine the total number of RBs actually occupied finally, thereby improving the system transmission performance in the case of UCI multiplexing with different priorities.

[0077] In the above method embodiments, the determination of the number of resource blocks RBs actually used based on the number of bits and code rates respectively corresponding to multiple independently encoded UCIs can be determined in multiple ways. The embodiments of the present application provide two determination methods and are introduced as follows respectively:

[0078] Method 1: The determination of the number of resource blocks RBs actually used based on the number of bits and code rates respectively corresponding to multiple independently encoded UCIs may include:

[0079] Determine the number of first resource elements (REs) actually used by the first UCI based on the number of bits of the first UCI and the first code rate, and determine the number of second REs actually used by the second UCI based on the number of bits of the second UCI and the second code rate;

[0080] Determine the number of resource blocks (RBs) actually used during multiplexed transmission of multiple UCIs based on the sum of the number of first REs and the number of second REs;

[0081] Among them, the first UCI and the second UCI are independently encoded, and the corresponding code rates are the first code rate and the second code rate respectively.

[0082] Specifically, the multiple UCIs are the first UCI and the second UCI respectively. The first UCI and the second UCI are encoded separately. Then, determine the number of first REs actually used by the first UCI based on the number of bits of the first UCI and the first code rate, determine the number of second REs actually used by the second UCI based on the number of bits of the second UCI and the second code rate, and determine the number of RBs actually used by multiple UCIs based on the sum of the number of first REs and the number of second REs.

[0083] The number of actually used RBs is represented by Then, the number of actually used RBs simultaneously satisfies the following conditions:

[0084] Condition 1:

[0085] Condition 2:

[0086] Condition 3:

[0087] Among them, is the number of RBs included in the same uplink channel resource determined based on the total number of bits of the multiplexed multiple UCIs; the number of bits corresponding to the first UCI is O A and the first code rate is R A ; the number of bits corresponding to the second UCI is O B and the second code rate is R B ; is the number of subcarriers used for UCI transmission on one RB; is the number of orthogonal frequency division multiplexing (OFDM) symbols included in the uplink channel resource for transmitting UCI; Q m is a preset value corresponding to the modulation method, and the value of Q m can be 1 or 2. For example, when using π / 2 BPSK modulation, the value of Q m is 1; when using QPSK modulation, the value of Q m is 2.

[0088] It is understandable that the above conditions can be applied to jointly determine the number of RBs actually used at a certain time. When it is the case of 1 RB, the number of RBs actually used is 1.

[0089] Furthermore, the method further includes:

[0090] If it is determined that the number of RBs actually used is

[0091] Method 2: Determining the number of resource blocks (RBs) actually used based on the number of bits and code rate respectively corresponding to multiple UCIs with independent coding may include:

[0092] Determining the number of first RBs actually used by the first UCI based on the number of bits and the first code rate of the first UCI, and determining the number of second RBs actually used by the second UCI based on the number of bits and the second code rate of the second UCI;

[0093] Determining the number of RBs actually used during multiplexed transmission of multiple UCIs based on the sum of the number of first RBs and the number of second RBs;

[0094] wherein, the first UCI and the second UCI are independently coded, and the corresponding code rates are the first code rate and the second code rate respectively.

[0095] Specifically, the multiple UCIs are respectively the first UCI and the second UCI, and the first UCI and the second UCI are respectively coded. Then, the number of first RBs actually used by the first UCI is determined based on the number of bits and the first code rate of the first UCI, the number of second RBs actually used by the second UCI is determined based on the number of bits and the second code rate of the second UCI, and the sum of the number of first RBs and the number of second RBs is used as the number of RBs actually used during multiplexed transmission of multiple UCIs.

[0096] The number of first RBs is represented by , then the number of first RBs actually used simultaneously satisfies the following conditions:

[0097] Condition 1:

[0098] Condition 2:

[0099] Condition 3:

[0100] The number of second RBs is represented by Indicates the number of the second RBs actually used Satisfies the following conditions simultaneously:

[0101] Condition 1:

[0102] Condition 2:

[0103] Condition 3:

[0104] If the number of RBs actually used is represented by then the number of RBs actually used is determined in the following manner:

[0105]

[0106] wherein is the number of RBs included in the same uplink channel resource determined based on the total number of bits of multiple UCIs for multiplexing; the number of bits corresponding to the first UCI is O A and the first code rate is R A ; the number of bits corresponding to the second UCI is O B and the second code rate is R B ; is the number of subcarriers for UCI transmission on one RB; is the number of orthogonal frequency division multiplexing (OFDM) symbols for UCI transmission included in the uplink channel resource; Q m is a preset value corresponding to the modulation mode, and the value of Q m can be 1 or 2. For example, when π / 2 BPSK modulation is used, the value of Q m is 1; when QPSK modulation is used, the value of Q m is 2.

[0107] It can be understood that when the above conditions can be applied to jointly determine the number of RBs actually used When i.e., in the case of 1 RB, the number of RBs actually used is 1.

[0108] Furthermore, the method further includes:

[0109] If or then determine that the number of RBs actually used is

[0110] In the above embodiments, the first code rate is the code rate corresponding to the resources occupied when the first UCI is transmitted alone; or, it is the code rate corresponding to the resources occupied when the first UCI and the second UCI are multiplexed and transmitted; the second code rate is the code rate corresponding to the resources occupied when the second UCI is transmitted alone.

[0111] Or,

[0112] The first code rate is the code rate corresponding to the resources occupied when the first UCI is transmitted alone; or, it is the code rate corresponding to the resources occupied when the first UCI and the second UCI are multiplexed and transmitted; the second code rate is the code rate configured by the network side.

[0113] Or,

[0114] The first code rate is the code rate configured by the network side; the second code rate is the code rate corresponding to the resources occupied when the second UCI is transmitted alone.

[0115] Or,

[0116] Both the first code rate and the second code rate are the code rates configured by the network side.

[0117] Wherein, the uplink channel is PUCCH, and the code rate configured by the network side is the code rate respectively configured for the resources of low-priority PUCCH format 0 and PUCCH format 1, and different PUCCH formats correspond to different code rates;

[0118] Or,

[0119] The code rate configured by the network side is the code rate for different-priority UCIs, and only low-priority UCIs are configured, or different-priority UCIs are configured separately.

[0120] For the UCI multiplexing resource determination method provided in the above embodiments of the present application, when multiple UCIs are multiplexed and transmitted on the PUCCH, based on the number of bits and the code rate corresponding to the independently encoded multiple UCIs, the number of RBs actually used for multiplexing transmission is determined, improving the system transmission efficiency.
