[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to U.S. Application No. 16 / 582,702, filed on September 25, 2019, which claims the benefit of and priority to U.S. Provisional Patent Application No. 62 / 737,646, filed on September 27, 2018, both of which are assigned to the assignee of the present disclosure and are hereby expressly incorporated herein by reference in their entireties as if fully set forth below and for all applicable purposes. Technical Field

[0004] Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for multiplexing hybrid automatic repeat request (HARQ) responses and channel state information (CSI) reports in a physical uplink control channel (PUCCH) in wireless communication networks such as 5th generation (5G) networks (also known as new radio (NR) networks). Background Art

[0005] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system, the LTE Advanced (LTE-A) system, the Code Division Multiple Access (CDMA) system, the Time Division Multiple Access (TDMA) system, the Frequency Division Multiple Access (FDMA) system, the Orthogonal Frequency Division Multiple Access (OFDMA) system, the Single Carrier Frequency Division Multiple Access (SC-FDMA) system, and the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, etc.

[0006] In some examples, a wireless multiple access communication system may include multiple base stations (BSs), each of which is capable of simultaneously supporting communication with multiple communication devices (also referred to as user equipment (UE)). In an LTE or LTE-A network, a set of one or more base stations may define an eNodeB (eNB). In other examples (e.g., in a next-generation new radio (NR) or 5G network), a wireless multiple access communication system may include multiple distributed units (DUs) (e.g., edge units (EUs), edge nodes (ENs), radio heads (RHs), smart radio heads (SRHs), transmission reception points (TRPs), etc.) communicating with multiple central units (CUs) (e.g., central nodes (CNs), access node controllers (ANCs), etc.), wherein a set of one or more distributed units communicating with a central unit may define an access node (e.g., may be referred to as a base station, 5G NB, next-generation NodeB (gNB or gNodeB), TRP, etc.). A base station or distributed unit may communicate with a set of UEs on a downlink channel (e.g., for transmission from a base station or to a UE) and an uplink channel (e.g., for transmission from a UE to a base station or distributed unit).

[0007] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, or even global scale. New Radio (NR) (e.g., 5G) is an example of an emerging telecommunication standard. NR is a collection of enhancements to the LTE mobile standard promulgated by 3GPP. It is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards using OFDMA with cyclic prefix (CP) on downlink (DL) and uplink (UL). To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0008] However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. Summary of the invention

[0079] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for multiplexing hybrid automatic repeat request (HARQ) responses and channel state information (CSI) reports in a physical uplink control channel (PUCCH) in a wireless communication network such as a fifth generation (5G) network.

[0080] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Without departing from the scope of the present disclosure, the functions and arrangements of the elements discussed may be changed. Various examples may appropriately omit, replace or add various processes or components. For example, the described method may be performed in an order different from that described, and various steps may be added, omitted or combined. Moreover, the features described with respect to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement a device or practice a method. In addition, the scope of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of the claims. The word "exemplary" is used herein to mean "used as an example, instance or illustration". Any aspect described as "exemplary" herein is not necessarily to be interpreted as being preferred or advantageous over other aspects.

[0081] The technology described herein can be used for various wireless communication technologies, such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms "network" and "system" are generally used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network can implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS).

[0082] New Radio (NR) is an emerging wireless communication technology developed together with the 5G Technology Forum (5GTF). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The technology described herein can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, although terms commonly associated with 3G and / or 4G wireless technologies may be used herein to describe various aspects, aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and beyond, including NR technology.

[0083] New Radio (NR) access (e.g., 5G technology) can support various wireless communication services, such as enhanced mobile broadband (eMBB) for wide bandwidth (e.g., 80 MHz or wider bandwidth) communications, millimeter wave (mmW) for high carrier frequency (e.g., 25 GHz or higher frequency) communications, massive machine type communication (mMTC) for non-backward compatible machine type communication (MTC) technology, and / or mission critical for ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet their respective quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.

[0084] Example Wireless Communication System

[0085] Figure 1 An example wireless communication network 100 is shown in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a new radio (NR) or 5G network. The following aspects of FIG. 11, Fig.12 and Fig.13 Systems and methods are described for avoiding out-of-order uplink data transmission upon data radio bearer (DRB) release or quality of service (QoS) flow addition in a wireless communication network.

[0086] like Figure 1As shown, the wireless network 100 may include multiple base stations (BS) 110 and other network entities. A BS may be a station that communicates with a user equipment (UE). Each BS 110 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a Node B (NB) and / or a Node B subsystem serving the coverage area, depending on the context in which the term "cell" is used. In the NR system, the term "cell" and the next generation NodeB (gNB), new radio base station (NR BS), 5G NB, access point (AP) or transmission reception point (TRP) may be interchangeable. In some examples, the cell may not necessarily be fixed, and the geographical area of ​​the cell may move according to the location of the mobile BS. In some examples, the base station may be interconnected to each other and / or to one or more other base stations or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (e.g., direct physical connection, wireless access, virtual network, etc.) using any suitable transmission network.

[0087] Typically, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, subcarrier, channel, tone, subband, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0088] A base station (BS) may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in the home, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown, BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.

[0089] The wireless communication network 100 may also include a relay station. A relay station receives transmissions of data and / or other information from an upstream station (e.g., a BS or a UE) and sends transmissions of data and / or other information to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown, a relay station 110r may communicate with a BS 110a and a UE 120r to facilitate communication between the BS 110a and the UE 120r. A relay station may also be referred to as a relay BS, a relay, or the like.

[0090] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relays, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 20 watts), while a pico BS, a femto BS, and a relay may have a lower transmit power level (e.g., 1 watt).

[0091] The wireless communication network 100 may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.

[0092] A network controller 130 may be coupled to a set of BSs and provide coordination and control for these BSs. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0093] UE 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premises equipment (CPE), cellular phone, smart phone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, appliance, medical device or medical equipment, biosensor / device, wearable device (e.g., smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music device, video device, satellite radio, etc.), vehicle assembly or sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate via wireless or wired medium. Some UEs may be considered as machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node can provide, for example, a connection to a network or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Internet of Things (IoT) devices, which can be narrowband IoT (NB-IoT) devices.

[0094] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are sent in the frequency domain using OFDM and in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing of the subcarriers can be 15kHz, and the minimum resource allocation (called a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be partitioned into subbands. For example, a subband may cover 1.08 MHz (ie, six resource blocks), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively.

[0095] Although various aspects of the examples described herein may be associated with LTE technology, various aspects of the present disclosure may be applicable to other wireless communication systems, such as NR. NR may utilize OFDM with CP on the uplink and downlink and include support for half-duplex operation using TDD. Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmissions with precoding may also be supported. MIMO configurations in the DL may support up to eight transmit antennas with multi-layer DL transmissions of up to eight streams and up to two streams per UE. Multi-layer transmissions with up to two streams per UE may be supported. Aggregation of multiple cells may be supported with up to eight serving cells.

[0096] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., a base station) allocates resources for communication between some or all devices and equipment within its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, the subordinate entity utilizes the resources allocated by the scheduling entity. The base station is not the only entity that can be used as a scheduling entity. In some examples, a UE may be used as a scheduling entity, and resources for one or more subordinate entities (e.g., one or more other UEs) may be scheduled, and other UEs may wirelessly communicate the resources scheduled by the UE. In some examples, a UE may be used as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In a mesh network example, in addition to communicating with a scheduling entity, UEs may also communicate directly with each other.

[0097] exist Figure 1 In FIG. 1 , a solid line with double-headed arrows indicates desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE on the downlink and / or uplink. A thin dashed line with double-headed arrows indicates interfering transmissions between a UE and a BS.

[0098] Figure 2 It shows that it can be Figure 1 An example logical architecture of a distributed radio access network (RAN) 200 implemented in the wireless communication network 100 is shown. A 5G access node 206 may include an access node controller (ANC) 202. The ANC 202 may be a central unit (CU) of the distributed RAN 200. A backhaul interface to a next generation core network (NG-CN) 204 may terminate at the ANC 202. A backhaul interface to an adjacent next generation access node (NG-AN) 210 may terminate at the ANC 202. The ANC 202 may include one or more transmission reception points (TRPs) 208 (e.g., cells, BSs, gNBs, etc.).

[0099] The TRP 208 may be a distributed unit (DU). The TRP 208 may be connected to a single ANC (e.g., ANC 202) or more than one ANC (not shown). For example, for RAN sharing, Radio as a Service (RaaS), and service-specific AND deployments, the TRP 208 may be connected to more than one ANC. The TRPs 208 may each include one or more antenna ports. The TRPs 208 may be configured to serve traffic to the UE individually (e.g., dynamically selected) or collectively (e.g., joint transmission).

[0100] The logical architecture of the distributed RAN 200 may support fronthaul solutions across different deployment types. For example, the logical architecture may be based on the transmitting network capabilities (eg, bandwidth, latency, and / or jitter).

[0101] The logical architecture of the distributed RAN 200 may share features and / or components with LTE. For example, the next generation access node (NG-AN) 210 may support dual connectivity with NR and may share a common fronthaul for LTE and NR.

[0102] The logical architecture of the distributed RAN 200 may enable collaboration between TRPs 208 (eg, within a TRP and / or across TRPs via the ANC 202). An inter-TRP interface may not be used.

[0103] Logical functions may be dynamically distributed in the logical architecture of the distributed RAN 200. Figure 5Describing in more detail, the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical layer (PHY) layer may be appropriately placed at the DU (e.g., TRP 208) or the CU (e.g., ANC 202).

[0104] Figure 3 An example physical architecture of a distributed radio access network (RAN) 300 according to aspects of the present disclosure is shown. A centralized core network unit (C-CU) 302 may host core network functions. The C-CU 302 may be centrally deployed. To handle peak capacity, the C-CU 302 functions may be offloaded (e.g., to Advanced Wireless Services (AWS)).

[0105] A centralized RAN unit (C-RU) 304 may host one or more ANC functions. Alternatively, the C-RU 304 may host core network functions locally. The C-RU 304 may have a distributed deployment. The C-RU 304 may be close to the network edge.

[0106] The DU 306 may host one or more TRPs (edge ​​nodes (EN), edge units (EU), radio heads (RH), smart radio heads (SRH), etc.) The DU may be located at the edge of the network with radio frequency (RF) capabilities.

[0107] Figure 4 1 shows a BS 110 and a UE 120 (eg, Figure 1 For example, antenna 452, processors 466, 458, 464 and / or controller / processor 480 of UE 120 and / or antenna 434, processors 420, 430, 438 and / or controller / processor 440 of BS 110 may be used to perform the various techniques and methods described herein (e.g., those described with respect to FIGS. 11, 12, and 13).

[0108] At BS110, a transmit processor 420 may receive data from a data source 412 and control information from a controller / processor 440. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. The processor 420 may process (e.g., encode and symbol map) the data and the control information to obtain data symbols and control symbols, respectively. The processor 420 may also generate reference symbols, such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a cell-specific reference signal (CRS). A transmit (TX) multiple-input multiple-output (MIMO) processor 430 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols (if applicable), and may provide an output symbol stream to modulators (MODs) 432a to 432t. Each modulator 432 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 432a through 432t may be transmitted via antennas 434a through 434t, respectively.

[0109] At the UE 120, antennas 452a to 452r may receive downlink signals from the base station 110 and may provide received signals to demodulators (DEMODs) in transceivers 454a to 454r, respectively. Each demodulator 454 may condition (e.g., filter, amplify, down-convert, and digitize) a corresponding received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 456 may obtain received symbols from all demodulators 454a to 454r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 458 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 460, and provide decoded control information to the controller / processor 480.

[0110] On the uplink, at the UE 120, a transmit processor 464 may receive and process data from a data source 462 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 480 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 464 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 464 may be precoded by a TX MIMO processor 466 (if applicable), further processed by a demodulator in the transceivers 454a to 454r (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the BS 110, the uplink signal from the UE 120 may be received by the antenna 434, processed by the modulator 432, detected by the MIMO detector 436 (if applicable), and further processed by the receive processor 438 to obtain decoded data and control information transmitted by the UE 120. The receive processor 438 may provide decoded data to a data sink 439 and decoded control information to a controller / processor 440 .

[0111] Controllers / processors 440 and 480 may direct operations at base station 110 and UE 120, respectively. Processor 440 and / or other processors and modules at BS 110 may perform or direct the execution of processes for the techniques described herein. Memories 442 and 482 may store data and program codes for BS 110 and UE 120, respectively. Scheduler 444 may schedule UEs for data transmission on the downlink and / or uplink.

[0112] Figure 5 A diagram 500 showing an example for implementing a communication protocol stack according to aspects of the present disclosure is shown. The communication protocol stack shown can be implemented by a device operating in a wireless communication system such as a 5G system (e.g., a system supporting uplink-based mobility). Diagram 500 shows a communication protocol stack, which includes a radio resource control (RRC) layer 510, a packet data convergence protocol (PDCP) layer 515, a radio link control (RLC) layer 520, a medium access control (MAC) layer 525, and a physical (PHY) layer 530. In various examples, the layers of the protocol stack can be implemented as separate modules of software, as part of a processor or ASIC, as part of a non-colocated device connected by a communication link, or various combinations thereof. Colocated and non-colocated implementations can be used, for example, in a protocol stack for a network access device (e.g., AN, CU, and / or DU) or a UE.

[0113] The first option 505-a illustrates a split implementation of the protocol stack, where the implementation of the protocol stack is performed on a centralized network access device (e.g., Figure 2 ANC 202 in ) and distributed network access equipment (e.g., Figure 2 In the first option 505-a, the RRC layer 510 and the PDCP layer 515 may be implemented by the central unit, and the RLC layer 520, the MAC layer 525, and the PHY layer 530 may be implemented by the DU. In various examples, the CU and the DU may be collocated or non-collocated. The first option 505-a may be useful in macro cell, micro cell, or pico cell deployments.

[0114] The second option 505-b shows a unified implementation of the protocol stack, where the protocol stack is implemented in a single network access device. In the second option, the RRC layer 510, the PDCP layer 515, the RLC layer 520, the MAC layer 525, and the PHY layer 530 can all be implemented by the AN. The second option 505-b can be useful in, for example, a femtocell deployment.

[0115] Regardless of whether the network access device implements part or all of the protocol stack, the UE can implement the entire protocol stack as shown in 505-c (e.g., RRC layer 510, PDCP layer 515, RLC layer 520, MAC layer 525, and PHY layer 530).

[0116] In LTE, the basic transmission time interval (TTI) or packet duration is a 1 millisecond subframe. In NR, the subframe is still 1ms, but the basic TTI is called a time slot. A subframe contains a variable number of time slots (e.g., 1, 2, 4, 8, 16, ... time slots) depending on the subcarrier spacing. NR RBs are 12 consecutive frequency subcarriers. NR can support a basic subcarrier spacing of 15KHz, and other subcarrier spacings such as 30kHz, 60kHz, 120kHz, 240kHz, etc. can be defined with respect to the basic subcarrier spacing. Symbol and time slot lengths scale with the subcarrier spacing. The CP length also depends on the subcarrier spacing.

[0117] Figure 6 is a diagram showing an example of a frame format 600 for NR. The transmission timeline for each of the downlink and uplink may be divided into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be divided into 10 subframes, each of which is 1 ms and indexed from 0 to 9. Each subframe may include a variable number of slots, depending on the subcarrier spacing. Each slot may include a variable number of symbol periods (e.g., 7 or 14 symbols), depending on the subcarrier spacing. The symbol periods in each slot may be indexed. A mini slot, which may be referred to as a subslot structure, refers to a transmission time interval having a duration less than a slot (e.g., 2, 3, or 4 symbols).

[0118] Each symbol in a slot may indicate a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction may be switched dynamically for each subframe. The link direction may be based on the slot format. Each slot may include DL / UL data and DL / UL control information.

[0119] In NR, a synchronization signal (SS) block is transmitted. The SS block includes PSS, SSS, and two symbols PBCH. It can be transmitted at fixed time slot positions (such as Figure 6 Symbols 0-3 shown in the figure send SS blocks. The UE can use PSS and SSS for cell search and acquisition. PSS can provide half-frame timing; SSS can provide CP length and frame timing. PSS and SSS can provide cell identification. PBCH carries some basic system information, such as downlink system bandwidth, timing information within a radio frame, periodicity of SS burst sets, system frame number, etc. SS blocks can be organized into SS bursts to support beam scanning (sweep). Further system information such as remaining minimum system information (RMSI), system information block (SIB), other system information (OSI) can be sent on the physical downlink shared channel (PDSCH) in certain subframes.

[0120] In some cases, two or more subordinate entities (e.g., UEs) can communicate with each other using sidelink signals. Practical applications of such sidelink communications may include public safety, proximity services, UE-to-network relays, vehicle-to-vehicle (V2V) communications, Internet of Things (IoE) communications, IoT communications, mission-critical mesh networks, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal that is communicated from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, licensed spectrum (unlike wireless local area networks that typically use unlicensed spectrum) may be used to communicate sidelink signals.

[0121] The UE may operate in various radio resource configurations, including a configuration associated with sending a pilot using a dedicated resource set (e.g., a radio resource control (RRC) dedicated state, etc.) or a configuration associated with sending a pilot using a common resource set (e.g., an RRC common state, etc.). When operating in the RRC dedicated state, the UE may select a dedicated resource set for sending a pilot signal to the network. When operating in the RRC common state, the UE may select a common resource set for sending a pilot signal to the network. In either case, the pilot signal sent by the UE may be received by one or more network access devices (such as an AN or DU or a portion thereof). Each receiving network access device may be configured to receive and measure pilot signals sent on a common resource set, and also receive and measure pilot signals sent on a dedicated resource set allocated to a UE, for which the network access device is a member of a monitoring set of the network access device of the UE. In one or more or (a plurality of) receiving network access devices to which the measured CUs send pilot signals, these measurements may be used to identify the serving cell of the UE or to initiate a change in the serving cell of one or more UEs.

[0122] Example multiplexing of HARQ and CSI on PUCCH

[0123] According to aspects of the present disclosure, a user equipment may use a physical uplink control channel (PUCCH) to send uplink control information (UCI) to a base station (e.g., a gNB). Different types of UCI include: a hybrid automatic repeat request (HARQ) response (e.g., acknowledgement and negative acknowledgement or ACK / NAK) indicating whether the UE has correctly received a downlink transport block, channel state information (CSI) that assists a base station (BS) in making scheduling determinations related to downlink channels, and a scheduling request (SR) requesting uplink resources for the UE to use to send data.

[0124] In NR, up to two PUCCHs can be scheduled per timeslot, where each of the two PUCCHs contains one or more UCI types.

[0125] In NR, the BS can semi-statically configure the UE with separate PUCCH resources for each type of UCI. These PUCCH resources can be time domain or frequency domain multiplexed and available in each time slot. If the UE has UCI to send, the UE sends the UCI via the PUCCH resources corresponding to that type of UCI.

[0126] In previously known technologies (e.g., NR), each PUCCH resource is configured by the BS and contains the following parameters:

[0127] 1. PUCCH Format Type - Indicates the common format level parameters to be applied to this PUCCH resource. All resources specified as the same format type share these common parameters;

[0128] 2. Starting symbol index - the initial symbol at which PUCCH transmission starts using this resource; and

[0129] 3. Symbol number - the number of consecutive symbols on which PUCCH is transmitted using this resource.

[0130] In previously known techniques, when a UE has both a HARQ response and CSI to be sent in a time slot and the separate PUCCH resources for the HARQ response and CSI overlap in time, the UE multiplexes the separate resources into a new combined PUCCH resource, which may have its own time domain behavior (i.e., starting symbol index and number of symbols, as described above). The new PUCCH resource is selected by the UE determining the combined payload of the HARQ response and CSI and selecting a PUCCH resource large enough to transmit the combined payload of the HARQ response and CSI. The new PUCCH resource may be different from any of the initial PUCCH resources. This practice of combining PUCCH resources is performed in an iterative loop until all overlapping PUCCH resources that the UE may have selected to send UCI in a time slot have been multiplexed.

[0131] In the previously known technology, a flag called a simultaneousHARQ-ACK-CSI flag (also referred to herein as a "simultaneousHARQ-ACK-CSI field" and a "HARQ-CSI flag") is a common parameter provided for each PUCCH format and is used to determine whether the HARQ response and the CSI can be multiplexed. If the flag is "false" or is not provided (for example, provided by the base station in the system information block (SIB)), the CSI is discarded and only the HARQ response is sent. In the case where the BS expects the HARQ response and the CSI to be multiplexed, the discarding of the CSI may cause some problems in the previously known technology.

[0132] In previously known techniques, each PUCCH format (e.g., by a base station) provides a simultaneous HARQ-ACK-CSI flag. PUCCH resources that may be used for HARQ response and CSI provision do not all provide a simultaneous HARQ-ACK-CSI flag. That is, a PUCCH resource that may be used for HARQ response does not provide a simultaneous HARQ-ACK-CSI flag, while a PUCCH resource used for CSI provides a simultaneous HARQ-ACK-CSI flag, or vice versa, or two PUCCH resources provide a simultaneous HARQ-ACK-CSI flag, wherein the first PUCCH resource indicates that the HARQ response and CSI can be multiplexed, while the second PUCCH resource indicates that the HARQ response and CSI cannot be multiplexed. In this case, the UE does not know whether to multiplex the HARQ response and CSI.

[0133] In previously known techniques, two separate PUCCH resources for HARQ response and CSI may both contain a simultaneousHARQ-ACK-CSI flag, but after multiplexing of the HARQ response and CSI, the UE selects a new PUCCH resource (for transmission of multiplexed HARQ response and CSI) that does not contain the flag (or the flag indicates that multiplexing of the HARQ response and CSI is disabled). In this case, there is ambiguity as to whether a PUCCH containing both the HARQ response and CSI should be sent on a PUCCH resource that does not allow multiplexing of the HARQ response and CSI.

[0134] Figure 77 is a time-frequency resource diagram 700 showing the above situation where both the PUCCH resource 702 for HARQ response (i.e., ACK 1 resource) and the PUCCH resource 704 for CSI (i.e., CSI 1 resource) include the simultaneousHARQ-ACK-CSI flag. As shown, the PUCCH resource 702 for HARQ response and the PUCCH resource 704 for the first CSI overlap in time, and therefore the UE multiplexes the HARQ response and the first CSI at 706. After the multiplexing of the HARQ response and the CSI, the UE selects a new PUCCH resource 708 (i.e., ACK 1+CSI 1 resource) that does not include the simultaneousHARQ-ACK-CSI flag (or the simultaneousHARQ-ACK-CSI flag for the PUCCH resource 708 indicates that the multiplexing of the HARQ response and CSI is disabled) at 706. In this case, there is ambiguity as to whether the UE should send a PUCCH containing both a HARQ response and CSI on PUCCH resources that do not allow multiplexing of HARQ response and CSI.

[0135] In the previously known technology, in the case where an intermediate PUCCH resource selected during the iterative cyclic combining process that does not allow multiplexing of HARQ response and CSI exists, but the PUCCH resource finally determined allows HARQ response and CSI to be multiplexed, CSI may also be discarded prematurely. In this case, when some PUCCH resources referenced during the iterative cyclic combining process do not allow multiplexing of HARQ response and CSI, there is ambiguity as to whether a PUCCH containing both HARQ response and CSI should be sent on the PUCCH resource.

[0136] Figures 8A-8C is a time-frequency resource diagram illustrating the above situation, in which the intermediate PUCCH resources selected during the iterative cyclic combining process that does not allow HARQ response and CSI multiplexing exist, but the finally determined PUCCH resources allow HARQ response and CSI to be multiplexed.

[0137] Fig. 8A800 is a time-frequency resource diagram showing the first cycle of the iterative cyclic combination process, wherein the intermediate PUCCH resources do not allow HARQ response and CSI multiplexing, but the finally determined PUCCH resources allow HARQ response and CSI to be multiplexed. As shown in the figure, in the first cycle of the iterative cyclic combination process, the UE has selected a first PUCCH resource 802 for HARQ response (i.e., ACK 1 resource), a second PUCCH resource 804 for the first CSI (i.e., CSI 1 resource), a third PUCCH resource 806 for SR (i.e., SR 1 resource), and a fourth PUCCH resource 808 for the second CSI (i.e., CSI 2 resource). As shown in the figure, the first PUCCH resource 802 for HARQ response, the second PUCCH resource 804 for the first CSI, and the third PUCCH resource 806 for SR overlap in time, and the UE therefore multiplexes the HARQ response, the first CSI, and the SR at 810. After multiplexing of the HARQ response, the first CSI, and the SR, the UE selects a new PUCCH resource 812 (i.e., ACK 1+CSI 1+SR 1 resource) at 810 that does not include a simultaneousHARQ-ACK-CSI flag (or a simultaneousHARQ-ACK-CSI flag for the PUCCH resource 812 indicating that multiplexing of the HARQ response and CSI is disabled). The new PUCCH resource 812 overlaps in time with the fourth PUCCH resource 808 for the second CSI, and the UE therefore determines that the second CSI should be multiplexed with the HARQ response, the first CSI, and the SR. However, in this case, it is ambiguous whether the UE should discard the first CSI because the simultaneousHARQ-ACK-CSI flag for the PUCCH resource 812 indicates that multiplexing of the HARQ response and CSI is disabled, as marked by a dashed "X" on the new PUCCH resource 812. If the UE discards the first CSI, the UE selects another PUCCH resource 814 for transmission of HARQ response and SR. As shown, PUCCH resource 814 overlaps in time with the fourth PUCCH resource 808 for the second CSI, and the UE therefore determines that the second CSI should be multiplexed with the HARQ response and SR.

[0138] Figure 8B is a time-frequency resource diagram 820 showing the second cycle of the iterative cyclic combination process, the first cycle of which is in Fig. 8AAs shown in the figure. As shown, in the first cycle of the iterative loop combining process, the UE does not discard the first CSI and selects a new PUCCH resource 812 (i.e., ACK 1+CSI 1+SR 1 resource) for multiplexed HARQ response, first CSI and SR that does not contain a simultaneousHARQ-ACK-CSI flag (or a simultaneousHARQ-ACK-CSI flag for PUCCH resource 812 indicates that multiplexing of HARQ response and CSI is disabled). The new PUCCH resource 812 overlaps in time with the fourth PUCCH resource 808 for the second CSI, and the UE therefore multiplexes the second CSI with the HARQ response, the first CSI and the SR at 822. Then, the UE selects PUCCH resource 824 for transmitting the multiplexed HARQ response, the first CSI, the SR and the second CSI.

[0139] Figure 8C is a time-frequency resource diagram 840 showing an alternative second cycle of an iterative cyclic combination process, the first cycle of which is in Fig. 8A As shown in the figure, in the first cycle of the iterative cyclic combining process, the UE discards the first CSI and selects a new PUCCH resource 814 (i.e., ACK 1+SR 1 resource) in which the simultaneousHARQ-ACK-CSI flag is enabled for the multiplexed HARQ response and SR. The new PUCCH resource 814 overlaps in time with the fourth PUCCH resource 808 for the second CSI, and the UE therefore multiplexes the second CSI with the HARQ response, the first CSI and the SR at 842. The UE then selects PUCCH resource 844 for transmitting the multiplexed HARQ response, the SR and the second CSI.

[0140] According to aspects of the present disclosure, a base station (e.g., a gNB) may send an indication (e.g., in a SIB) that a simultaneous HARQ-ACK-CSI flag applies to all PUCCHs. For example, the simultaneous HARQ-ACK-CSI flag is moved out of PUCCH-formatConfig and into the highest level of PUCCH-Config. In this example, applying the simultaneous HARQ-ACK-CSI flag at the PUCCH-Config level aligns the flag across all PUCCH formats and has the added benefit of reducing base station signaling.

[0141] In aspects of the present disclosure, the UE may receive signaling (e.g., from a base station in a SIB) indicating that the simultaneous HARQ-ACK-CSI flag applies to all PUCCHs. If the simultaneous HARQ-ACK-CSI flag is enabled, the UE may multiplex CSI and HARQ responses in all PUCCH resources.

[0142] Fig. 9 is a diagram showing that a UE (eg, Figure 1 and Figure 4 Flowchart of operation 900 for wireless communication performed by a UE 120 (shown) to multiplex CSI and HARQ response in PUCCH. At box 902, operation 900 begins with the UE receiving an indication from a base station (BS) to enable multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) in all physical uplink control channel (PUCCH) resources. Operation 900 continues at box 904, and the UE generates a first CSI report on a first downlink (DL) channel from the BS. At box 906, operation 900 continues with the UE multiplexing the HARQ response and the first CSI report for the transmission from the BS in the PUCCH. Operation 900 continues at box 908, and the UE sends the PUCCH to the BS via one of the PUCCH resources.

[0143] According to aspects of the present disclosure, in block 906, the UE performing operation 900 may multiplex a HARQ response, a first CSI report, and a scheduling request (SR) in a PUCCH.

[0144] In an aspect of the present disclosure, the UE performing operation 900 may multiplex the second CSI report on the second DL channel from the BS with the HARQ response and the first CSI report in the PUCCH.

[0145] Fig.10 is a diagram showing that a BS (e.g., Figure 1 and Figure 4 1000 for wireless communication performed by the BS 110 shown in FIG. 1000 to enable multiplexing of CSI and HARQ responses in the PUCCH. Operation 1000 may be considered as the above reference Fig. 9The operation 1000 is supplementary to the operation 900 described above. At block 1002, the operation 1000 begins with the BS sending an indication to a user equipment (UE) to enable multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) in all physical uplink control channel (PUCCH) resources. The operation 1000 continues at block 1004, with the BS receiving a PUCCH from the UE via one of the PUCCH resources, wherein the PUCCH includes a HARQ response to a transmission from the BS, the HARQ response being multiplexed with a first CSI report on a first downlink channel to the UE. At block 1006, the operation 1000 continues with the BS demultiplexing the first CSI report and the HARQ response from the PUCCH.

[0146] According to aspects of the present disclosure, the PUCCH may include a scheduling request (SR) from the UE, and the BS performing operation 1000 may demultiplex the SR from the PUCCH.

[0147] In aspects of the present disclosure, the PUCCH may include a second CSI report on the first DL channel or the second DL channel to the UE, and the BS performing operation 1000 may demultiplex the second CSI report from the PUCCH.

[0148] According to aspects of the present disclosure, demultiplexing the HARQ response, CSI report and / or SR from the PUCCH (e.g., as described in block 1006 of operation 1000) may include: demodulating the PUCCH; decoding the PUCCH; and / or determining the HARQ response, CSI report and / or SR.

[0149] In aspects of the present disclosure, the UE may prepare an initial set of PUCCH resources to be multiplexed by checking the simultaneousHARQ-ACK-CSI flag in the various HARQ and CSI resources to be multiplexed. After these initial checks, the UE considers the simultaneousHARQ-ACK-CSI checks complete. During the iterative cyclic combining process, the UE continues to multiplex HARQ and CSI on the newly selected PUCCH resources even if one or more of the newly selected PUCCH resources containing the multiplexed UCI do not have the simultaneousHARQ-ACK-CSI flag set.

[0150] FIG. 11A to FIG. 11Bis a time-frequency resource diagram showing the above case where the UE prepares an initial set of PUCCH resources to be multiplexed by checking the simultaneousHARQ-ACK-CSI flag in the various HARQ and CSI resources to be multiplexed. After these initial checks, the UE considers the simultaneousHARQ-ACK-CSI check complete and multiplexes the HARQ response and CSI on the final selected set of PUCCH resources, even if one or more of the newly selected PUCCH resources containing the multiplexed UCI do not have the simultaneousHARQ-ACK-CSI flag set.

[0151] Fig.11A1 is a time-frequency resource diagram 1100 showing the first cycle of the iterative cyclic combining process, in which the UE can prepare an initial set of PUCCH resources to be multiplexed by checking the simultaneousHARQ-ACK-CSI flags between the various HARQ and CSI resources to be multiplexed, and then after these initial checks, the UE considers the simultaneousHARQ-ACK-CSI checks to be complete. As shown in the figure, in the first cycle of the iterative cyclic combining process, the UE has selected a first PUCCH resource 1102 for HARQ response (i.e., ACK 1 resource), a second PUCCH resource 1104 for the first CSI (i.e., CSI 1 resource), a third PUCCH resource 1106 for SR (i.e., SR 1 resource) and a fourth PUCCH resource 1108 for the second CSI (i.e., CSI 2 resource). The UE checks that each of the PUCCH resources 1102, 1104, 1106, and 1108 has an enabled simultaneousHARQ-ACK-CSI flag, and determines that overlapping PUCCH resources containing HARQ responses or CSI can be multiplexed. As shown, the first PUCCH resource 1102 for the HARQ response, the second PUCCH resource 1104 for the first CSI, and the third PUCCH resource 1106 for the SR overlap in time, and the UE therefore multiplexes the HARQ response, the first CSI, and the SR at 1110. After multiplexing of the HARQ response, the first CSI, and the SR, the UE selects a new PUCCH resource 1112 (i.e., ACK 1+CSI 1+SR 1 resource) that does not contain a simultaneousHARQ-ACK-CSI flag (or the simultaneousHARQ-ACK-CSI flag for the PUCCH resource 1112 indicates that multiplexing of the HARQ response and CSI is disabled) at 1110. Because the UE previously determined that the overlapping PUCCH resources 1102, 1104, 1106, and 1108 can be multiplexed, the UE does not consider the lost or disabled simultaneous HARQ-ACK-CSI flag for the PUCCH resource 1112. The new PUCCH resource 1112 overlaps in time with the fourth PUCCH resource 1108 for the second CSI, and the UE therefore determines that the second CSI should be multiplexed with the HARQ response, the first CSI, and the SR.

[0152] Fig. 11B is a time-frequency resource diagram 1120 showing the second cycle of the iterative cyclic combination process, the first cycle of which is in Fig.11AAs shown in the figure, in the first loop of the iterative loop combining process, the UE selects a new PUCCH resource 1112 (i.e., ACK 1+CSI 1+SR 1 resource) for multiplexed HARQ response, first CSI and SR that does not contain a simultaneousHARQ-ACK-CSI flag (or a simultaneousHARQ-ACK-CSI flag for PUCCH resource 1112 indicates that multiplexing of HARQ response and CSI is disabled). The new PUCCH resource 1112 overlaps in time with the fourth PUCCH resource 1108 for the second CSI, and the UE therefore multiplexes the second CSI with the HARQ response, the first CSI and the SR at 1122. Then, the UE selects PUCCH resource 1124 for transmitting the multiplexed HARQ response, the first CSI, the SR and the second CSI.

[0153] Fig.12 is a diagram showing that a UE (eg, Figure 1 and Figure 4 120) for wireless communication to multiplex CSI and HARQ response in PUCCH. At block 1202, operation 1200 begins with the UE receiving multiple indications from a base station (BS), wherein each indication indicates that multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource. Operation 1200 continues at block 1204, where the UE generates a first CSI report on a first downlink (DL) channel from the BS, wherein the first CSI report corresponds to a first PUCCH resource corresponding to a first indication in the multiple indications. At block 1206, operation 1200 continues with the UE obtaining a HARQ response to a transmission from the BS, wherein the HARQ response corresponds to a second PUCCH resource corresponding to a second indication in the multiple indications. Operation 1200 continues at block 1208, where the UE determines to multiplex the HARQ response and the first CSI report in PUCCH based on the first indication and the second indication. At block 1210, operations 1200 continue with the UE multiplexing the HARQ response and the first CSI report in the PUCCH. Operations 1200 continue at block 1212 with the UE sending the PUCCH to the BS via a third PUCCH resource corresponding to the PUCCH.

[0154] According to aspects of the present disclosure, in block 1210, the UE performing operation 1200 may multiplex a HARQ response, a first CSI report, and a scheduling request (SR) in a PUCCH.

[0155] In an aspect of the present disclosure, the UE performing operation 1200 may multiplex the second CSI report on the first DL channel or the second DL channel from the BS with the HARQ response and the first CSI report in the PUCCH.

[0156] Fig.13 is a diagram showing that a BS (e.g., Figure 1 and Figure 4 10) for wireless communication to enable multiplexing of CSI and HARQ responses in PUCCH. Operation 1300 may be considered as the above reference Fig.12 The operation 1200 described above is in addition to the operation 1200 described above. At block 1302, the operation 1300 begins with the BS sending a plurality of indications to a user equipment (UE), wherein each indication indicates enabling multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) on a corresponding physical uplink control channel (PUCCH) resource. The operation 1300 continues at block 1304, with the BS receiving a PUCCH from the UE via a first resource of the PUCCH resources, wherein the PUCCH includes a HARQ response to a transmission from the BS, the HARQ response being multiplexed with a first CSI report on a first downlink channel to the UE, wherein: the first CSI report corresponds to a second PUCCH resource corresponding to a first indication of the plurality of indications, and the HARQ response corresponds to a third PUCCH resource corresponding to a second indication of the plurality of indications. At block 1306, the operation 1300 continues with the BS determining, based on the first indication and the second indication, that the PUCCH includes a HARQ response multiplexed with the first CSI report. Operations 1300 continue at block 1308 with the BS demultiplexing the first CSI report and the HARQ response from the PUCCH.

[0157] According to aspects of the present disclosure, the PUCCH may include a scheduling request (SR) from the UE, and the BS performing operation 1300 may demultiplex the SR from the PUCCH.

[0158] In aspects of the present disclosure, the PUCCH may include a second CSI report on the first DL channel or the second DL channel to the UE, and the BS performing operation 1300 may demultiplex the second CSI report from the PUCCH.

[0159] According to aspects of the present disclosure, demultiplexing the HARQ response, CSI report and / or SR from the PUCCH (e.g., as described in block 1308 of operation 1300) may include: demodulating the PUCCH; decoding the PUCCH; and / or determining the HARQ response, CSI report and / or SR.

[0160] In aspects of the present disclosure, the UE may not perform a check of the simultaneousHARQ-ACK-CSI flag on the PUCCH resources at the beginning of the iterative cyclic combining process, but still multiplex all HARQ responses and CSI on the overlapping PUCCH resources as described earlier in this document. At the end of the multiplexing process, the UE checks the simultaneousHARQ-ACK-CSI flag for the final set of PUCCH resources and discards the CSI (but using the same selected PUCCH resources) if the flag is not set.

[0161] FIG. 14A to FIG. 14B is a time-frequency resource diagram showing the above case where the UE does not check the simultaneous HARQ-ACK-CSI flag on the initial set of PUCCH resources to be multiplexed. Instead, the UE checks the simultaneous HARQ-ACK-CSI flag for the final set of PUCCH resources and discards the CSI (but uses the same selected PUCCH resources) if the flag is not set.

[0162] Fig.14A1400 is a time-frequency resource diagram showing the first cycle of the iterative cyclic combining process, in which the UE does not check the simultaneous HARQ-ACK-CSI flag on the initial set of PUCCH resources to be multiplexed, but instead only checks the simultaneous HARQ-ACK-CSI flag for the final set of PUCCH resources, and if the flag is not set, the CSI is discarded (but the same selected PUCCH resource is used). As shown, in the first cycle of the iterative cyclic combining process, the UE has selected a first PUCCH resource 1402 for a HARQ response (i.e., ACK 1 resource), a second PUCCH resource 1404 for a first CSI (i.e., CSI 1 resource), a third PUCCH resource 1406 for SR (i.e., SR 1 resource), and a fourth PUCCH resource 1408 for a second CSI (i.e., CSI 2 resource). As shown, the first PUCCH resource 1402 for the HARQ response, the second PUCCH resource 1404 for the first CSI, and the third PUCCH resource 1406 for the SR overlap in time, and the UE therefore multiplexes the HARQ response, the first CSI, and the SR at 1410. After multiplexing of the HARQ response, the first CSI, and the SR, the UE selects a new PUCCH resource 1412 (i.e., ACK 1+CSI 1+SR 1 resource) that does not contain a simultaneous HARQ-ACK-CSI flag (or the simultaneous HARQ-ACK-CSI flag for the PUCCH resource 1112 indicates that multiplexing of the HARQ response and CSI is disabled) at 1410. Because the UE only checks the simultaneous HARQ-ACK-CSI flag for the final set of PUCCH resources, the UE does not consider the lost or disabled simultaneous HARQ-ACK-CSI flag of the PUCCH resource 1412. The new PUCCH resource 1412 overlaps in time with the fourth PUCCH resource 1408 for the second CSI, and the UE therefore determines that the second CSI should be multiplexed with the HARQ response, the first CSI, and the SR.

[0163] Fig. 14B is a time-frequency resource diagram 1420 showing the second cycle of the iterative cyclic combination process, the first cycle of which is in Fig.14AAs shown in the figure, in the first loop of the iterative loop combining process, the UE selects a new PUCCH resource 1412 (i.e., ACK 1+CSI 1+SR 1 resource) for multiplexed HARQ response, first CSI and SR that does not contain a simultaneousHARQ-ACK-CSI flag (or a simultaneousHARQ-ACK-CSI flag for PUCCH resource 1412 indicates that multiplexing of HARQ response and CSI is disabled). The new PUCCH resource 1412 overlaps in time with the fourth PUCCH resource 1408 for the second CSI, and the UE therefore multiplexes the second CSI with the HARQ response, the first CSI and the SR at 1422. Then, the UE selects PUCCH resource 1424 for transmitting the multiplexed HARQ response, the first CSI, the SR and the second CSI. The PUCCH resource 1424 does not contain a simultaneous HARQ-ACK-CSI flag (or the simultaneous HARQ-ACK-CSI flag for the PUCCH resource 1424 indicates that multiplexing of the HARQ response and CSI is disabled), and the UE therefore drops the first CSI and the second CSI, as marked by a dashed "X" on the PUCCH resource 1424 containing the multiplexed HARQ response, the first CSI, the SR, and the second CSI. The UE instead sends the multiplexed HARQ response and the SR via the PUCCH resource 1424.

[0164] Fig.15 is a diagram showing that a UE (eg, Figure 1 and Figure 4 1500 is a flowchart of operations 1500 for wireless communication performed by a UE 120 (shown) to multiplex CSI and HARQ responses in a PUCCH. At box 1502, operations 1500 begin with the UE receiving multiple indications from a base station (BS), wherein each indication indicates whether multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource. Operation 1500 continues at box 1504, where the UE generates a first CSI report on a first downlink (DL) channel from the BS. At box 1506, operations 1500 continue with the UE obtaining a HARQ response to a transmission from the BS. Operation 1500 continues at box 1508, where the UE multiplexes the HARQ response and the first CSI report in a PUCCH, where the PUCCH corresponds to a first PUCCH resource corresponding to a first indication of the multiple indications. At block 1510, operations 1500 continue with the UE determining, based on the first indication, not to discard the first CSI report in the PUCCH. Operations 1500 continue at block 1512 with the UE sending the PUCCH to the BS via the first PUCCH resource.

[0165] According to aspects of the present disclosure, in block 1508, the UE performing operation 1500 may multiplex a HARQ response, a first CSI report, and a scheduling request (SR) in a PUCCH.

[0171] In aspects of the present disclosure, the simultaneous HARQ-ACK-CSI flags for all PUCCH resources may be constrained (e.g., by a base station operating in accordance with a network standard) to have the same value, i.e., all simultaneous HARQ-ACK-CSI flags are enabled or all are disabled. A BS operating in this manner may send signaling in accordance with previously known techniques (i.e., in accordance with previously known network standards) while preventing the ambiguity previously described regarding multiplexing of HARQ responses and CSI in PUCCH.

[0172] According to aspects of the present disclosure, the UE may determine that a simultaneous HARQ-ACK-CSI flag for a PUCCH resource is enabled, and in response, determine to enable multiplexing of HARQ responses and CSI for all PUCCH resources. Similarly, the UE may determine that a simultaneous HARQ-ACK-CSI flag for a PUCCH resource is disabled, and in response, determine to disable multiplexing of HARQ responses and CSI for all PUCCH resources.

[0173] Fig.17 is a diagram showing that a UE (eg, Figure 1 and Figure 4 1700 is a flowchart of operations 1700 for wireless communication performed by a UE 120 (shown in FIG. 1700 ) to multiplex CSI and HARQ responses in a PUCCH. At block 1702, operations 1700 begin with the UE receiving multiple indications from a base station (BS), wherein each indication indicates whether multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource. Operation 1700 continues at block 1704, where the UE determines to enable multiplexing of HARQ information and CSI in all PUCCH resources based on a first indication in the multiple indications. At block 1706, operations 1700 continue with the UE generating a first CSI report on a first downlink (DL) channel from the BS. Operation 1700 continues at block 1708, where the UE multiplexes the HARQ response and the first CSI report to the transmission from the BS in the PUCCH. Operations 1700 continue at block 1710 with the UE sending a PUCCH to the BS via one of the PUCCH resources.

[0174] According to aspects of the present disclosure, in block 1708, the UE performing operation 1700 may multiplex a HARQ response, a first CSI report, and a scheduling request (SR) in a PUCCH.

[0175] In an aspect of the present disclosure, the UE performing operation 1700 may multiplex the second CSI report on the first DL channel or the second DL channel from the BS with the HARQ response and the first CSI report in the PUCCH.

[0176] Fig.18 is a diagram showing that a BS (e.g., Figure 1 and Figure 4 1800 for wireless communication performed by the BS 110 shown in FIG. 1800 to enable multiplexing of CSI and HARQ responses in the PUCCH. Operation 1800 may be considered as the above reference Fig.17 The operation 1700 described above is supplementary to the operation 1700 described above. At block 1802, the operation 1800 begins with the BS sending a plurality of indications to a user equipment (UE), wherein each indication indicates whether multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource. Operation 1800 continues at block 1804, with the BS receiving a PUCCH from the UE via a first PUCCH resource of the PUCCH resources, wherein the PUCCH includes a HARQ response to a transmission from the BS, the HARQ response being multiplexed with a first CSI report on a first downlink (DL) channel to the UE. At block 1806, the operation 1800 continues with the BS determining to enable multiplexing of HARQ information and CSI in all PUCCH resources based on a first indication of the plurality of indications, wherein the first indication does not correspond to the first PUCCH resource. Operation 1800 continues at block 1808, with the BS demultiplexing the first CSI report and the HARQ response from the PUCCH.

[0177] According to aspects of the present disclosure, the PUCCH may include a scheduling request (SR) from the UE, and the BS performing operation 1800 may demultiplex the SR from the PUCCH.

[0178] In aspects of the present disclosure, the PUCCH may include a second CSI report on the first DL channel or the second DL channel to the UE, and the BS performing operation 1800 may demultiplex the second CSI report from the PUCCH.

[0179] According to aspects of the present disclosure, demultiplexing the HARQ response, CSI report and / or SR from the PUCCH (e.g., as described in block 1808 of operation 1800) may include: demodulating the PUCCH; decoding the PUCCH; and / or determining the HARQ response, CSI report and / or SR.

[0180] In aspects of the present disclosure, a BS (e.g., a gNB) may selectively configure a simultaneousHARQ-ACK-CSI flag differently for a PUCCH format (e.g., which corresponds to a PUCCH resource), with the condition that if the flag is enabled for a PUCCH format with a smaller payload size, the flag is also set for all PUCCH formats with a larger payload size than the PUCCH format for which the flag is enabled. During the multiplexing process, a UE with (multiple) HARQ responses and CSI reports to send looks ahead and determines the format and simultaneousHARQ-ACK-CSI flag of the PUCCH resources to be used to send the multiplexed UCI. If the flag is true, the UE continues to multiplex HARQ and CSI on the PUCCH resources. Otherwise, the UE discards the CSI and multiplexes only the rest of the UCI for transmission in the PUCCH on the PUCCH resources.

[0181] Fig.19A1 is a time-frequency resource diagram 1900 showing the first cycle of the iterative cyclic combining process, wherein the determined PUCCH resources do not allow HARQ response and CSI multiplexing. As shown, in the first cycle of the iterative cyclic combining process, the UE has selected a first PUCCH resource 1902 for HARQ response (i.e., ACK 1 resource), a second PUCCH resource 1904 for the first CSI (i.e., CSI 1 resource), a third PUCCH resource 1906 for SR (i.e., SR 1 resource), and a fourth PUCCH resource 1908 for the second CSI (i.e., CSI 2 resource). As shown, the first PUCCH resource 1902 for HARQ response, the second PUCCH resource 1904 for the first CSI, and the third PUCCH resource 1906 for SR overlap in time, and the UE therefore looks forward to potential new PUCCH resources 1912 for sending multiplexed HARQ response, first CSI, and SR. The UE determines that the new PUCCH resource 1912 (i.e., ACK 1+CSI 1+SR 1 resource) does not contain a simultaneousHARQ-ACK-CSI flag (or the simultaneousHARQ-ACK-CSI flag for the PUCCH resource 1912 indicates that multiplexing of the HARQ response and CSI is disabled), and therefore determines not to use the PUCCH resource 1912 to transmit the HARQ response, the first CSI, and the SR, as marked by a dashed "X" on the PUCCH resource 1912. The UE determines at 1910 to discard the first CSI and multiplex the HARQ response and the SR. After multiplexing of the HARQ response and the SR, the UE selects a new PUCCH resource 1914 (i.e., ACK 1+SR 1 resource) for the HARQ response and the SR. The new PUCCH resource 1914 overlaps in time with the fourth PUCCH resource 1908 for the second CSI, and as described herein, the UE may determine that the second CSI should be multiplexed with the HARQ response and the SR in the second cycle.

[0182] Fig.19B1 is a time-frequency resource diagram 1920 showing the first cycle of the iterative cyclic combining process, in which a PUCCH resource smaller than the determined PUCCH resource allows HARQ response and CSI multiplexing. As shown, in the first cycle of the iterative cyclic combining process, the UE has selected a first PUCCH resource 1922 for HARQ response (i.e., ACK 1 resource), a second PUCCH resource 1924 for the first CSI (i.e., CSI 1 resource), a third PUCCH resource 1926 for SR (i.e., SR 1 resource), and a fourth PUCCH resource 1928 for the second CSI (i.e., CSI 2 resource). As shown, the first PUCCH resource 1922 for the HARQ response, the second PUCCH resource 1924 for the first CSI, and the third PUCCH resource 1926 for the SR overlap in time, and the UE therefore looks forward to a potential new PUCCH resource 1932 for sending the multiplexed HARQ response, the first CSI, and the SR. The UE determines a new PUCCH resource 1932 (i.e., ACK 1+CSI 1+SR 1 resource) with a simultaneous HARQ-ACK-CSI flag enabled based on the PUCCH resource 1924, which has a smaller payload size than the PUCCH resource 1932 with the simultaneous HARQ-ACK-CSI flag enabled. At 1930, the UE multiplexes the HARQ response, the first CSI, and the SR. The new PUCCH resource 1932 overlaps in time with the fourth PUCCH resource 1928 for the second CSI, and as described herein, the UE can determine that the second CSI should be multiplexed with the HARQ response, the first CSI, and the SR in the second cycle.

Operation 2000 continues at block 2004, where the UE determines based on a first indication in the multiple indications to enable multiplexing of HARQ information and CSI in a first PUCCH resource and all PUCCH resources having a larger payload size than the first PUCCH resource. At block 2006, operation 2000 continues with the UE generating a first CSI report on a first downlink (DL) channel from the BS. Operation 2000 continues at block 2008 with the UE multiplexing a HARQ response to a transmission from the BS and the first CSI report in the PUCCH. Operations 2000 continue at block 2010 with the UE sending a PUCCH to the BS via one of the PUCCH resources having a larger payload size than the first PUCCH resource.

Operation 2100 may be considered as the above reference Fig. 20A supplement to the described operation 2000. At box 2102, operation 2100 begins with the BS sending multiple indications to a user equipment (UE), wherein each indication indicates whether multiplexing of hybrid automatic repeat request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource. Operation 2100 continues at box 2104, where the BS determines, based on a first indication in the multiple indications, to enable multiplexing of HARQ information and CSI in a first PUCCH resource and all PUCCH resources having a larger payload size than the first PUCCH resource. At box 2106, operation 2100 continues with the BS receiving a PUCCH from the UE via a second PUCCH resource having a larger payload size than the first PUCCH resource, wherein the PUCCH includes a HARQ response to a transmission from the BS, the HARQ response being multiplexed with a first CSI report on a first downlink (DL) channel to the UE.

[0233] The various operations of the above method can be performed by any suitable component capable of performing the corresponding function. The component may include various hardware and / or software components and / or modules, including but not limited to circuits, application specific integrated circuits (ASICs) or processors. Generally, where operations are shown in the accompanying drawings, the corresponding corresponding components plus functional components of these operations may have similar numbers.

[0234] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or performed with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but alternatively, the processor may be any commercially available processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration.

[0235] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. The bus may include any number of interconnecting buses and bridges, depending on the specific application and overall design constraints of the processing system. The bus may link together various circuits including a processor, a machine-readable medium, and a bus interface. The bus interface may be used to connect a network adapter, etc., to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In the user terminal 120 (see Figure 1 ), a user interface (e.g., keyboard, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits, such as timing sources, peripherals, voltage regulators, power management circuits, etc., which are well known in the art and will not be described in detail. The processor may be implemented with one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits that can execute software. Those skilled in the art will recognize how to best implement the described functionality of the processing system depending on the specific application and the overall design constraints imposed on the entire system.

[0236] If implemented in software, these functions may be stored or sent as one or more instructions or codes on a computer-readable medium. Software should be broadly interpreted as referring to instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or other. Computer-readable media include both computer storage media and communication media, and communication media include any media that facilitates the transfer of computer programs from one place to another. The processor may be responsible for managing the bus and conventional processing, including executing software modules stored on a machine-readable storage medium. A computer-readable storage medium may be coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium. Alternatively, the storage medium may be integrated into the processor. For example, a machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium on which instructions separated from a wireless node are stored, all of which may be accessed by the processor through a bus interface. Alternatively or additionally, the machine-readable medium or any portion thereof may be integrated into the processor, such as where there may be a cache and / or a general register file. Examples of machine-readable storage media may include, for example, RAM (random access memory), flash memory, ROM (read only memory), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. The machine-readable medium may be embodied in a computer program product.

[0237] A software module may include a single instruction or multiple instructions and may be distributed over several different code segments, between different programs, and over multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a sending module and a receiving module. Each software module may reside in a single storage device or be distributed across multiple storage devices. For example, when a triggering event occurs, a software module may be loaded from a hard drive into a RAM. During the execution of a software module, the processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When referring to the functions of the following software modules, it will be understood that such functions are implemented by the processor when instructions from the software module are executed.

[0238] Moreover, any connection is properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, server or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology (such as infrared (IR), radio and microwave), the definition of medium includes coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology (such as infrared, radio and microwave). Disks and optical disks used herein include compact disks (CDs), laser optical disks, optical disks, word versatile disks (DVDs), floppy disks, and Blu-ray disks, where disks typically copy data magnetically, while optical disks copy data optically via lasers. Therefore, in some aspects, computer-readable media may include non-temporary computer-readable media (e.g., tangible media). In addition, for other aspects, computer-readable media may include temporary computer-readable media (e.g., signals). The above combinations should also be included within the scope of computer-readable media.

[0239] Thus, some aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having instructions stored (and / or encoded) thereon, the instructions being executable by one or more processors to perform the operations described herein. For example, a computer program product for performing the operations described herein and Fig. 9 , 10 , 12, 13, 15 and 16.

[0240] In addition, it should be understood that the modules and / or other appropriate devices for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by the user terminal and / or base station (if applicable). For example, such a device can be coupled to a server to facilitate the transfer of components for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage device (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or a floppy disk, etc.), so that the user terminal and / or base station can obtain the various methods when the storage component is coupled or provided to the device. Moreover, any other suitable technology for providing the methods and techniques described herein to the device can be utilized.
