AI Technical Summary
Existing wireless communication systems, particularly in 5G NR, face challenges in efficiently reporting channel state information (CSI) due to limitations in multiplexing CSI reports with physical uplink shared channel (PUSCH) repetitions, especially in scenarios involving multiple transmit and receive points (TRPs) and different beam configurations.
The method involves determining the number of symbols and UCI presence in each PUSCH repetition to optimize CSI report multiplexing, allowing CSI reports to be transmitted on specific PUSCH repetitions associated with different SRS sets, thereby enhancing reliability and efficiency through multi-beam diversity.
This approach improves the reliability and efficiency of CSI reporting by ensuring that CSI reports are transmitted on optimal PUSCH repetitions, even in the presence of varying beam configurations and multiple TRPs, thereby enhancing communication quality.

[Technical field]
[0002] FIELD OF THE DISCLOSURE
[0002] The present disclosure relates generally to communication systems, and more particularly, to wireless communications with channel state information (CSI) reports. [Background technology]
[0003] Introduction
[0003] Wireless communication systems have been widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.
[0004]
[0004] These multiple access technologies are being adopted in various telecommunication standards to provide a common protocol that allows different wireless devices to communicate on a city, national, regional, or even global scale. An exemplary telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuing mobile broadband evolution promulgated by the 3rd Generation Partnership Project (3GPP®) to meet new requirements related to latency, reliability, security, scalability (e.g., for the Internet of Things (IoT)), and other requirements. 5G NR includes services related to enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE®) standard. Further improvements in 5G NR technology are needed. These improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the Invention
[0005]
[0005] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an exhaustive overview of all contemplated aspects, nor is it intended to identify key or critical elements of all aspects or to delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
[0006] In one aspect of the present disclosure, a method, a computer-readable medium, and an apparatus for wireless communication in a user equipment (UE) are provided, the apparatus receiving downlink control information (DCI) scheduling a plurality of physical uplink shared channel (PUSCH) repetitions, the PUSCH repetitions including a first set of PUSCH repetitions associated with a first sounding reference signal (SRS) set and a second set of PUSCH repetitions associated with a second SRS set. The apparatus determines whether to multiplex the at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions, in one PUSCH repetition of the second set of PUSCH repetitions, or in both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on at least one of whether a number of symbols differs in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions, or whether uplink control information (UCI) excluding the at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions. The apparatus multiplexes and transmits the at least one CSI report on one PUSCH repetition of the first set of PUSCH repetitions, on one PUSCH repetition of the second set of PUSCH repetitions, or on both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions, based on the determination.

[0009]
[0038] The detailed description of the invention described below with reference to the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description of the invention includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.
[0010]
[0039] Next, several aspects of a telecommunications system are presented with respect to various apparatus and methods that are described in the detailed description that follows and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.
[0011]
[0040] As an example, an element, or any portion of an element, or any combination of elements, may be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chips (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout this disclosure. One or more processors in a processing system may execute software. Software should be broadly construed to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, and the like, regardless of whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0012]
[0041] Thus, in one or more exemplary embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on a computer-readable medium or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. A storage medium may be any available medium that can be accessed by a computer. By way of example and not limitation, such computer-readable media may comprise random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of several types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.
[0013]
[0042] Although aspects and implementations are described in this application by way of illustration for some examples, those skilled in the art will appreciate that additional implementations and use cases may occur in many different configurations and scenarios. The innovations described herein may be implemented across many different platform types, devices, systems, shapes, sizes, and packaging configurations. For example, implementations and / or uses may occur via integrated chip implementations and other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, artificial intelligence (AI)-enabled devices, etc.). Although some examples may or may not be specifically targeted to a use case or application, a wide combination of applicability of the described innovations may occur. Implementations may range from chip-level or modular components to non-modular non-chip-level implementations, and even aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, transmitting and receiving wireless signals necessarily includes several components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processor(s), interleavers, adders / adders, etc.). It is intended that the innovations described herein may be practiced in a wide variety of devices of different sizes, shapes and configurations, chip-level components, systems, distributed configurations, aggregated or disaggregated components, end-user devices, etc.
[0014]
[0043] 1 illustrates an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., 5G core (5GC)). The base station 102 may include macro cells (high power cellular base stations) and / or small cells (low power cellular base stations). The macro cells include base stations. The small cells include femto cells, pico cells, and micro cells.
[0015]
[0044] In some aspects, the UE 104 may include a CSI report multiplexing determination component 198 configured to determine whether to multiplex one or more CSI reports in a PUSCH repetition and / or in which PUSCH repetition to multiplex one or more CSI reports for a multi-TRP PUSCH repetition. In one configuration, the CSI report multiplexing determination component 198 may be configured to receive a DCI scheduling a plurality of PUSCH repetitions, including a first set of PUSCH repetitions associated with a first SRS set and a second set of PUSCH repetitions associated with a second SRS set, requesting transmission of at least one CSI report to be multiplexed in one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions. In such a configuration, the CSI report multiplexing determination component 198 may determine whether to multiplex the at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions, in one PUSCH repetition of the second set of PUSCH repetitions, or in both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on at least one of whether a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions, or whether UCI excluding the at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions.In such a configuration, the CSI report multiplexing determination component 198 may multiplex and transmit at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions, in one PUSCH repetition of the second set of PUSCH repetitions, or in both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on the determination.
[0016]
[0045] A base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 through a first backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with the core network 190 through a second backhaul link 184. In addition to other functions, the base stations 102 may perform one or more of the following functions: forwarding of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracing, RAN information management (RIM), paging, positioning, and distribution of alert messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through the EPC 160 or the core network 190) over the third backhaul link 134 (e.g., an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.
[0017]
[0046] In some aspects, the network entity may include one or more components of a base station, a disaggregated or virtualized base station (e.g., a distributed unit or a central unit), a radio unit, a transmit receive point (TRP), a relay, an intelligent reflective surface (IRS), and / or a combination thereof. For example, the base station 102 or 180 may be referred to as a RAN and may include aggregated or disaggregated components. As an example of a disaggregated RAN, a base station may include a central / centralized unit (CU) 103, one or more distributed units (DU) 105, and / or one or more radio units (RU) 109, as shown in FIG. 1. The RAN may be disaggregated by a split between the RU 109 and the aggregated CU / DU. The RAN may be disaggregated by a split between the CU 103, the DU 105, and the RU 109. The RAN may be disaggregated by a split between the CU 103 and the aggregated DU / RU. The CU 103 and one or more DUs 105 may be connected via an F1 interface. The DUs 105 and the RUs 109 may be connected via a fronthaul interface. The connection between the CU 103 and the DUs 105 may be referred to as a midhaul, and the connection between the DUs 105 and the RUs 109 may be referred to as a fronthaul. The connection between the CU 103 and the core network may be referred to as a backhaul. The RAN may be based on a functional split between various components of the RAN, e.g., between the CU 103, the DUs 105, or the RUs 109. The CU may be configured to implement one or more aspects of a wireless communication protocol, e.g., handling one or more layers of a protocol stack, and the DU(s) may be configured to handle other aspects of the wireless communication protocol, e.g., other layers of the protocol stack. In different implementations, the split between layers handled by the CU and layers handled by the DU may be performed at different layers of the protocol stack.As one non-limiting example, the DU 105 may provide logical nodes for hosting a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and at least a portion of a Physical (PHY) layer based on a functional split. The RU may provide logical nodes configured to host at least a portion of the PHY layer and Radio Frequency (RF) processing. The CU 103 may host higher layer functions above the RLC layer, such as, for example, a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, etc. In other implementations, the split between layer functions provided by the CU, DU, or RU may be different.
[0018]
[0047] An access network may include one or more IAB nodes 111 that exchange wireless communications with UEs 104 or other integrated access and backhaul (IAB) nodes 111 to provide access and backhaul to a core network. In an IAB network of multiple IAB nodes, an anchor node may be referred to as an IAB donor. An IAB donor may be a base station 102 or 180 that provides access to a core network 190 or an EPC 160 and / or control over one or more IAB nodes 111. An IAB donor may include a CU 103 and a DU 105. An IAB node 111 may include a DU 105 and a mobile termination (MT) 113. The DU 105 of an IAB node 111 may act as a parent node, and the MT 113 may act as a child node.
[0019]
[0048] The base stations 102 may wirelessly communicate with the UE 104. Each of the base stations 102 may provide communication coverage to a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells may be known as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB) that may serve a closed group known as a closed subscriber group (CSG). A communication link 120 between the base station 102 and the UE 104 may include uplink (UL) transmissions (also referred to as a reverse link) from the UE 104 to the base station 102, and / or downlink (DL) transmissions (also referred to as a forward link) from the base station 102 to the UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be through one or more carriers. The base station 102 / UE 104 may use spectrum with up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) bandwidth per carrier allocated in a carrier aggregation with up to Yx MHz total (x component carriers) used for transmission in each direction. The carriers may be adjacent or non-adjacent to each other. The carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).
[0020]
[0049] Several UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 may use DL / UL WWAN spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.
[0021]
[0050] The wireless communication system may further include a Wi-Fi access point (AP) 150 in communication with a Wi-Fi station (STA) 152 via a communication link 154, such as in the 5 GHz unlicensed frequency spectrum. When communicating in the unlicensed frequency spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communicating to determine if a channel is available.
[0022]
[0051] The small cell 102' may operate in licensed and / or unlicensed frequency spectrums. When operating in an unlicensed frequency spectrum, the small cell 102' may employ NR and use the same unlicensed frequency spectrum (e.g., 5 GHz, etc.) used by the Wi-Fi AP 150. A small cell 102' employing NR in an unlicensed frequency spectrum may enhance coverage to and / or increase capacity of an access network.
[0023]
[0052] The electromagnetic spectrum is often subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. A similar naming issue sometimes arises with respect to FR2, which is often referred to (interchangeably) as the "millimeter wave" band in documents and papers, even though FR2 is different from the extremely high frequency (EHF) bands (30 GHz - 300 GHz) identified as "millimeter wave" bands by the International Telecommunications Union (ITU).
[0024]
[0053] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified these mid-band frequency operating bands as frequency range designation FR3 (7.125 GHz to 24.25 GHz). Frequency bands that fall within FR3 may inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6 GHz to 71 GHz), FR4 (71 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.
[0025]
[0054] With the above aspects in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz," as used herein, may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that unless otherwise specified, terms such as "millimeter wave," as used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.
[0026]
[0055] The base station 102, whether a small cell 102′ or a large cell (e.g., a macro base station), may include and / or be referred to as an eNB, g Node B (gNB), or another type of base station. Some base stations, such as the gNB 180, may operate in a conventional sub-6 GHz spectrum, in millimeter wave frequencies, and / or at near millimeter wave frequencies in communication with the UE 104. When the gNB 180 operates at millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. The millimeter wave base station 180 may utilize beamforming 182 with the UE 104 to compensate for path loss and short range. The base station 180 and the UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to enable beamforming.
[0027]
[0056] The base station 180 may transmit a beamformed signal to the UE 104 in one or more transmit directions 182′. The UE 104 may receive a beamformed signal from the base station 180 in one or more receive directions 182″. The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions. The base station 180 may receive a beamformed signal from the UE 104 in one or more receive directions. The base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of the base station 180 / UE 104. The transmit direction and receive direction for the base station 180 may be the same or different. The transmit direction and receive direction for the UE 104 may be the same or different.
[0028]
[0057] The EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are forwarded through the Serving Gateway 166, which is itself connected to the PDN Gateway 172. The PDN Gateway 172 provides IP address allocation for the UE as well as other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176. The IP services 176 may include Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may act as an entry point for content provider MBMS transmissions, may be used to authorize and start MBMS bearer services in a Public Land Mobile Network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to deliver MBMS traffic to base stations 102 that belong to a Multicast Broadcast Single Frequency Network (MBSFN) area that broadcasts a particular service, and may be responsible for session management (start / stop) and collecting eMBMS-related charging information.
[0029]
[0058] The core network 190 may include an access and mobility management function (AMF) 192, another AMF 193, a session management function (SMF) 194, and a user plane function (UPF) 195. The AMF 192 may be in communication with an integrated data management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. Generally, the AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are forwarded through the UPF 195. The UPF 195 provides IP address allocation for the UE as well as other functions. The UPF 195 is connected to IP services 197. The IP services 197 may include the Internet, intranet, IP multimedia subsystem (IMS), packet switched (PS) streaming (PSS) services, and / or other IP services.

[0060] FIG. 2A is a diagram 200 illustrating an example of a first subframe in a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of a DL channel in a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe in a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of a UL channel in a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD) where for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to either DL or UL, or may be time division duplex (TDD) where for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to both DL and UL. In the example provided by FIG. 2A, FIG. 2C, the 5G NR frame structure is assumed to be TDD, subframe 4 is configured with slot format 28 (mostly DL), where D is DL, U is UL, and F is flexible for use between DL / UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3 and 4 are shown with slot formats 1 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and UL, respectively. The other slot formats 2-61 include a mix of DL, UL, and flexible symbols. The UE is configured with the slot format through a received slot format indicator (SFI) (dynamically through DL control information (DCI) or semi-statically / statically through radio resource control (RRC) signaling). Note that the following description also applies to a 5G NR frame structure that is TDD.
[0032]
[0061] 2A-2D illustrate a frame structure, and aspects of the present disclosure may be applicable to other wireless communication technologies, which may have different frame structures and / or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. A subframe may also include a minislot, which may include 7, 4, or 2 symbols. Depending on whether the cyclic prefix (CP) is normal or extended, each slot may include 14 or 12 symbols. For a normal CP, each slot may include 14 symbols, and for an extended CP, each slot may include 12 symbols. The symbols on the DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on the UL can be CP-OFDM symbols (for high throughput scenarios) or Discrete Fourier Transform (DFT) Spread OFDM (DFT-s-OFDM) symbols (also called Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-limited scenarios limited to single stream transmission). The number of slots in a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) and the symbol length / duration, which is effectively equal to 1 / SCS.
[0033] [Table 1]
[0034]
[0062] For the normal CP (14 symbols / slot), the different numerologies μ0-4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For the extended CP, numerology 2 allows 4 slots per subframe. Thus, for the normal CP and numerology μ, 14 symbols / slot and 2 μ There are slots / subframes. The subcarrier spacing is 2 μ*15 kHz, where μ is a numerology 0-4. Thus, numerology μ=0 has a subcarrier spacing of 15 kHz, and numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figures 2A-2D provide an example of a normal CP with 14 symbols per slot and a numerology μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see Figure 2B) that are frequency division multiplexed. Each BWP may have a specific numerology and CP (normal or extended).
[0035]
[0063] A resource grid can be used to represent the frame structure. Each time slot contains a resource block (RB) (also called a physical RB (PRB)) that spans 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0036]
[0064] As shown in Figure 2A, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (shown as R for one particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).
[0037]
[0065] FIG. 2B illustrates an example of various DL channels in a subframe of a frame. A physical downlink control channel (PDCCH) carries DCI in one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including 6 RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. The PDCCHs in one BWP may be referred to as a control resource set (CORESET). A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during a PDCCH monitoring occasion on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be in symbol 2 of a particular subframe of a frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identity. The secondary synchronization signal (SSS) may be in symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH), which carries the master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also called SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data and broadcast system information not transmitted through the PBCH, such as the system information block (SIB), and paging messages.
[0038]
[0066] As shown in FIG. 2C, some of the REs carry DM-RS (denoted as R for one particular configuration, although other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and depending on the particular PUCCH format used. The UE may transmit a sounding reference signal (SRS). The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and the UE may transmit the SRS on one of the combs. The SRS may be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
[0039]
[0067] FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as shown in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQIs), precoding matrix indicators (PMIs), rank indicators (RIs), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may be further used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCIs.
[0040]
[0068] 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, IP packets from the EPC 160 may be provided to a controller / processor 375. The controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes a Radio Resource Control (RRC) layer, and Layer 2 includes a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Medium Access Control (MAC) layer. The controller / processor 375 controls RRC layer functions related to broadcasting of system information (e.g., MIBs, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting, as well as PDCP layer functions related to header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions, as well as RLC layer functions related to transfer of upper layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs, as well as mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) and MAC SDUs from the TBs. It provides MAC layer functions related to demultiplexing of SDUs, scheduling information reporting, error correction via HARQ, priority handling and logical channel prioritization.
[0041]
[0069] The transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions related to various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) coding / decoding of the transport channel, interleaving, rate matching, mapping onto the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., pilot) in the time domain and / or frequency domain, and then combined with each other using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain OFDM symbol stream. The OFDM streams are spatially precoded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimates may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate a radio frequency (RF) carrier with a respective spatial stream for transmission.
[0042]
[0070] At the UE 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement Layer 1 functions related to various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier and the reference signal are recovered and demodulated by determining the most likely signal constellation point transmitted by the base station 310. These soft decisions may be based on channel estimates calculated by a channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to a controller / processor 359, which implements Layer 3 and Layer 2 functions.
[0043]
[0071] The controller / processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 performs demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0044]
[0072] Similar to the functions described with respect to DL transmission by the base station 310, the controller / processor 359 provides RRC layer functions related to system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting, as well as PDCP layer functions related to header compression / decompression and security (encryption, decryption, integrity protection, integrity verification), as well as RLC layer functions related to transfer of upper layer PDUs, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs, as well as MAC layer functions related to mapping between logical channels and transport channels, multiplexing and demultiplexing of MAC SDUs onto and from the TB, scheduling information reporting, error correction via HARQ, priority handling, and logical channel prioritization.
[0045]
[0073] Channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select an appropriate coding and modulation scheme and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.
[0046]
[0074] The UL transmission is processed at the base station 310 in a manner similar to that described for the receiver functions at the UE 350. Each receiver 318RX receives a signal via its respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides the information to the RX processor 370.
[0047]
[0075] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the UE 350. The IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0048]
[0076] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to implement aspects related to the CSI report multiplexing determination component 198 of FIG.
[0049]
[0077] To improve data transmission and successful transmission rates, a transmitting device such as a base station or a UE may transmit data (e.g., via a PDSCH, PUSCH, etc.) with repetition / retransmission (e.g., PDSCH repetition, PUSCH repetition, etc.). For example, a UE may be configured to transmit N (e.g., 2, 4, 5, etc.) repetitions following a PUSCH. Thus, a UE may transmit N PUSCH repetitions after transmitting a PUSCH. Transmitting data with repetitions of data may increase the chances that the data is received by a receiving device, thus improving the success rate of transmission. For purposes of this disclosure, the terms "repetition" and "retransmission" may be used interchangeably and may refer to a copy or duplication of data that may be transmitted more than once. For example, PUSCH repetition and PUSCH retransmission may both refer to a copy / duplication of a PUSCH transmitted by a UE after the UE transmits a PUSCH.
[0050]
[0078] 4 is a diagram 400 illustrating an example of data transmission with repetition. A UE 402 may be configured to transmit a PUSCH 406 to a base station 404 (or to a component of the base station 404 or a network entity) with four repetitions / retransmissions. In one example, the UE 402 may transmit a PUSCH 406 in slot n, and then the UE 402 may transmit a first PUSCH repetition 408 (e.g., repetition #0) in slot n+1, a second PUSCH repetition 410 (e.g., repetition #1) in slot n+2, a third PUSCH repetition 412 (e.g., repetition #2) in slot n+3, and a fourth PUSCH repetition 414 (e.g., repetition #3) in slot n+4. The repeated transmission of the PUSCH 406 may also be referred to as inter-slot repetition. Although diagram 400 shows repetitions of PUSCH 406 transmitted on consecutive slots (e.g., PUSCH repetitions 408, 410, 412, and 414), repetitions may also be transmitted in non-consecutive slots (e.g., at n+1, n+3, n+5, etc.) or within the same slot (e.g., intra-slot repetition).
[0051]
[0079] In some examples, a network may include different data repetition types or modes. For example, a network may include at least two types of PUSCH repetitions for its dynamic grant (DG) and / or configured grant (CG). FIG. 5 is a diagram 500 illustrating an example of a first type of PUSCH repetition, which may be referred to as "PUSCH repetition Type A." In PUSCH repetition type A, if more than one PUSCH repetition (e.g., K>1) is configured for a UE, the UE may be configured to transmit a number K of PUSCH repetitions in multiple slots using the same time and frequency resources, and the UE may not transmit PUSCH or PUSCH repetitions across slot boundaries for DG PUSCH and / or CG PUSCH. When a UE is scheduled by a base station (or a component of a base station) to transmit a PUSCH or PUSCH repetition, the base station may indicate to the UE the resources that the UE can use to transmit the PUSCH or PUSCH repetition. For example, the base station may transmit a start and length indicator value (SLIV) to the UE, where the SLIV may indicate / include (e.g., in symbols) the start symbol (S) and length (L) of the PUSCH that the UE can use to transmit the PUSCH or PUSCH repetition in the slot. For example, as shown in diagram 500, the base station may configure the UE to transmit four PUSCH repetitions (e.g., K=4), and the base station may provide the UE with a SLIV indicating S=3 and L=10. Based on the SLIV, the UE may determine that the UE can use 10 symbols starting from symbol #3 of the slot (e.g., the fourth symbol of slot n since the first symbol may be symbol #0) to transmit a PUSCH repetition.If the UE is configured to transmit more than one PUSCH repetition (e.g., K>1), the UE may apply the same SLIV to all PUSCH repetitions so that each PUSCH repetition may be transmitted using the same time and frequency resources of a slot. In other words, in PUSCH repetition type A, if the same symbol (e.g., the same starting symbol and the same length) may be used for the PUSCH repetition of each slot, the UE may transmit different PUSCH repetitions in different slots. The number of repetitions K may be either semi-statically set (e.g., via RRC) or dynamically indicated by DCI (e.g., a Time Domain Resource Allocation (TDRA) field). For example, in an RRC configuration, if the UE is configured with pusch-AggregationFactor, the number of repetitions K may be equal to pusch-AggregationFactor. In a dynamic indication, if numberofrepetitions is presented in a TDRA table, the number of repetitions K may be equal to the numberofrepetitions indicated by the DCI (eg, pointing to a TDRA row).
[0052]
[0080] FIG. 6 is a diagram 600 illustrating an example of a second type of PUSCH repetition, which may be referred to as "PUSCH repetition Type B." In PUSCH repetition Type B, for DG PUSCH and / or CG PUSCH, the UE may transmit PUSCH across slot boundaries, and the UE may transmit PUSCH or PUSCH repetitions using different time and / or frequency resources for different slots. The base station (or a component of the base station) may also dynamically indicate the number of PUSCH repetitions, the inter-nominal PUSCH frequency hopping, the new uplink / downlink (U / D) symbol interactions, and / or the new SLIV to the UE under the second type of PUSCH repetition. For example, the base station may indicate the number of "nominal" repetitions to the UE in the DCI, which may be consecutive. The number of nominal repetitions (e.g., numberofrepetitions) may be set per row in the TDRA table or may be dynamically indicated by the DCI (by pointing to a TDRA row). In some examples, as shown by diagram 600 in FIG. 6, the nominal repetitions may have the same length (e.g., two nominal repetitions, each of which is four symbols long). As shown in diagrams 610 and 620, the nominal repetitions may cross a slot boundary. However, when a nominal repetition crosses a slot boundary, the nominal repetition may be split into two "actual repetitions." For example, when one of the four-symbol long repetitions in diagram 610 crosses a slot boundary, this repetition may be split into two effective repetitions. Thus, four nominal repetitions may turn into five effective repetitions. Similarly, when the 14-symbol repetition in diagram 620 crosses a slot boundary, the repetition may be split into two effective repetitions.
[0053]
[0081] In addition, if one or more of the nominal repetitions are identified as invalid symbols, the nominal repetition may also be split into multiple effective repetitions after removing the invalid symbols. FIG. 7 is a diagram 700 illustrating an example of splitting a nominal repetition into multiple effective repetitions based on invalid symbols and across slot boundaries. A UE may be scheduled by a base station (or a component of a base station) with four nominal repetitions, each having a length of five symbols, where one of the nominal repetitions may include an invalid symbol and one of the nominal repetitions may cross a slot boundary. A nominal repetition that includes an invalid symbol may be split into two effective repetitions after removing the invalid symbol, and a nominal repetition that crosses a slot boundary may be split into two effective repetitions. In this way, four nominal repetitions may be split into six effective repetitions. In some examples, the invalid symbol(s) may include semi-static downlink (DL) symbols, symbols indicated in a pattern of invalid symbols, synchronization signal block (SSB) symbols, and / or symbol(s) for which CORESET0 for Type0-PDCCH is monitored, etc.
[0054]
[0082] To improve the reliability and robustness of PUSCH transmission, the UE may be configured to transmit the PUSCH to multiple transmit reception points (TRPs) and / or antennas / panels. Thus, when a PUSCH transmitted to one TRP / panel is blocked, another repetition of the PUSCH may be received and decoded by the other TRP / panel (thus improving diversity). In some examples, different PUSCH transmission occasions (i.e., PUSCH repetitions) corresponding to the same transport block (TB) may be transmitted in different slots (e.g., for PUSCH repetition type A) or minislots (e.g., for PUSCH repetition type B). As described with respect to Figures 4-7, the number of PUSCH repetitions (e.g., K) may be RRC configured and / or dynamically indicated through the TDRA field of the DCI. In such examples, the UE may transmit the PUSCH repetitions using the same beam, since the Sounding Reference Signal (SRS) Resource Indicator (SRI) field of the DCI may apply to all repetitions. The SRI (e.g., SRS resource indicator) may be a field in a DCI (e.g., UL DCI) that determines / indicates the beam and / or power control for the PUSCH by pointing to one or more SRS resources in an SRS resource set. However, when different PUSCH repetitions are configured to be received on different TRPs, panels, and / or antennas of the base station, it may not be optimal to transmit all PUSCH repetitions using the same transmit beam. Therefore, in some examples, the UE may be configured to transmit different PUSCH repetitions on different transmit beams.
[0055]
[0083] FIG. 8 is a diagram 800 illustrating an example of associating different sets of PUSCH repetitions with different UL beams and power control parameters. In one example, a base station (or a component of a base station) may schedule / configure a set of four PUSCH repetitions for one UE, which may include a first PUSCH repetition 802, a second PUSCH repetition 804, a third PUSCH repetition 806, and a fourth PUSCH repetition 808. The set of PUSCH repetitions may be divided into two sets of PUSCH repetitions, where each set of PUSCH repetitions may be associated with a different beam and / or power control parameter than the other set of PUSCH repetitions. For example, a first set of PUSCH repetitions may include a first PUSCH repetition 802 and a third PUSCH repetition 806, and the first set of PUSCH repetitions may be associated with a first UL beam and / or a first set of power control parameters. In this manner, the UE may transmit a first set of PUSCH repetitions to the first TRP of the base station based on the first UL beam and / or the first set of power control parameters. Similarly, the second set of PUSCH repetitions may include the second PUSCH repetition 804 and the fourth PUSCH repetition 808, and the second set of PUSCH repetitions may be associated with the second UL beam and / or the second set of power control parameters. In this manner, the UE may transmit a second set of PUSCH repetitions to the second TRP of the base station based on the second UL beam and / or the second set of power control parameters, etc. In other words, the two sets of PUSCH repetitions may correspond to two SRS resource sets, in which case the DCI may indicate two sets of two beams / power control parameters by indicating one or more SRS resources in each of the two SRS resource sets.
[0056]
[0084] In order for the base station to determine the channel condition between the base station and the UE, the base station may request or configure the UE to measure the channel and report the channel measurements to the base station. For example, the base station may transmit a set of channel state information (CSI) reference signals (RS) to the UE and request / configure the UE to measure a set of CSI-RS. After measuring the CSI-RS, the UE may transmit one or more reports (e.g., CSI reports) to the base station via a PUSCH indicating the CSI. Based on the reported CSI, the base station may determine the channel condition between the base station and the UE, and based on the reported CSI, the base station may adjust one or more communication parameters between the base station and the UE to improve communication between the base station and the UE.
[0057]
[0085] In some examples, the base station may configure / trigger CSI reporting from the UE to be aperiodic (AP) (e.g., using PUSCH), periodic (e.g., using PUCCH), and / or semi-persistent (SP) (e.g., using PUCCH or DCI-activated PUSCH). FIG. 9 is a diagram 900 illustrating an example of triggering AP-CSI reporting on PUSCH. The base station (or a component of the base station) may trigger the UE to transmit AP-CSI reports on PUSCH via DCI (e.g., UL DCI), in which case the base station may configure up to 128 trigger states for the UE via RRC (e.g., via higher layer parameter AperiodicTriggerStateList), where each trigger state may be associated with one or more (e.g., up to 16) CSI report settings. In one example, if the "CSI Request" field in the DCI has N bits, up to 2 N -1 trigger state can be activated through the MAC-CE. For example, if the CSI request field in the DCI is 6 bits (e.g., N=6), then a maximum of 63 (e.g., 2 6A number of (-1=63) trigger states may be activated through the MAC-CE, which may be mapped to up to 63 codepoints. For example, as shown in FIG. 900, if the value (e.g., codepoint) of the CSI request field in the UL DCI corresponds to zero, it may indicate that no CSI report is triggered; if the value of the CSI request field corresponds to one, it may indicate that the first (#1) and third (#3) CSI report settings / configurations are triggered; if the value of the CSI request field corresponds to two, it may indicate that the fourth (#4) CSI report setting / configuration is triggered, etc. In other words, the CSI request field of the UL DCI may indicate one trigger state, which may trigger one or more CSI report settings / configurations.
[0058]
[0086] In some examples, if a base station requests a UE to provide an AP-CSI report via a DCI that also schedules multiple PUSCH repetitions, the UE may be configured to multiplex one or more AP-CSI reports on the first PUSCH repetition, which may be true for both PUSCH repetition type A and PUSCH repetition type B. For example, referring back to FIG. 5, if a base station requests a UE to provide AP-CSI reporting via a DIC that also schedules four PUSCH repetitions (e.g., K=4) based on PUSCH repetition type A, the UE may be configured to multiplex one or more AP-CSI reports on the first PUSCH repetition (e.g., in slot n) but not on other PUSCH repetitions. On the other hand, if the PUSCH repetition is based on PUSCH repetition type B and the UE is configured with one or more nominal repetitions, the UE may be configured to multiplex one or more AP-CSI reports on the first effective PUSCH repetition but not on other PUSCH repetitions.
[0059]
[0087] FIG. 10 is a diagram 1000 illustrating an example of AP-CSI reporting for PUSCH repetition type B. A UE may be configured with two nominal repetitions under PUSCH repetition type B, each nominal repetition having a six symbol length (e.g., L=6). In one example, a first nominal repetition may include an invalid symbol and a second nominal repetition may cross a slot boundary. As described in connection with FIG. 6 and FIG. 7, the two nominal repetitions may be split into four effective repetitions due to the invalid symbol and crossing a slot boundary. Thus, a UE may be configured to multiplex one or more AP-CSI reports on a first effective PUSCH repetition but not on other effective PUSCH repetitions. In some examples, a UE may not expect a first effective repetition to have a single symbol period.
[0060]
[0088] In another example, if the PUSCH does not include a TB (e.g., UL-SCH indicator=0 in the DCI, which may indicate that the UE has no data to transmit), the UE may assume the number of repetitions to be 1 (e.g., K=1) regardless of the number of repetitions (e.g., numberofrepetitions) configured for the UE. For example, if the UE is configured with four nominal repetitions (e.g., K=4) for the PUSCH, but the PUSCH does not include a TB, the UE may assume the nominal repetition to be 1 instead of 4. In addition, the UE may be configured to expect / assume that the length of the first nominal repetition is the same as the first effective repetition (e.g., no segmentation due to crossing an invalid symbol(s) or slot boundary, etc.).
[0061]
[0089] 11 is a diagram 1100 illustrating an example of triggering SP-CSI reporting on a PUSCH. A base station (or a component of a base station) may trigger a UE to transmit an SP-CSI report on a PUSCH via a DCI (e.g., a UL DCI), in which case the base station may configure up to 64 trigger states for the UE via RRC signaling (e.g., via a higher layer parameter SemiPersistentOnPUSCH-TriggerStateList), and each trigger state may be associated with one CSI report setting / configuration. In other words, a CSI request field in the DCI may point to one trigger state, which triggers a corresponding CSI report setting / configuration. For example, as shown in FIG. 1100, if the value of the CSI request field in the DCI corresponds to zero, the first (#1) CSI report setting / configuration may be triggered; if the value of the CSI request field corresponds to one, the fourth (#4) CSI report setting / configuration may be triggered; if the value of the CSI request field corresponds to 63, the seventh (#7) CSI report setting / configuration may be triggered, etc.
[0062]
[0090] FIG. 12 is a diagram 1200 illustrating an example of SP-CSI reporting. After a UE is activated to transmit an SP-CSI report via a DCI by a base station (or a component of a base station), the UE may be configured to periodically transmit a PUSCH 1202 carrying the CSI report until another DCI deactivates the SP-CSI reporting. The PUSCH 1202 carrying the CSI report may not carry a TB, and the DCI activating the SP-CSI reporting may be scrambled with an SP-CSI Radio Network Temporary Identifier (RNTI) (SP-CSI-RNTI). In addition, the periodicity 1204 between two consecutive PUSCHs 1202 may be configured in each CSI reporting configuration (e.g., with the reporting configuration type set to semiPersistentOnPUSCH) in terms of the number of slots (e.g., reportSlotConfig). In some examples, a parameter P0alpha may also be configured for each CSI report configuration, and this parameter may determine P0 (offset) and alpha (factor for partial path loss (PL) compensation) for power control of a PUSCH carrying an SP-CSI report corresponding to the CSI report configuration.
[0063]
[0091] In one aspect of the present disclosure, if SP-CSI reporting on PUSCH is activated by an activating DCI, each PUSCH may include one PUSCH repetition, in which case multiple repetitions (e.g., two or more PUSCH repetitions) may not be supported for SP-CSI reporting on PUSCH. For example, the UE may assume the number of repetitions to be 1 (e.g., K=1) regardless of the number of repetitions configured / indicated. In other words, the UE may assume the number of repetitions to be 1 regardless of the value / parameter of numberofrepetitions configured for the UE.
[0064]
[0092] 13 is a diagram 1300 illustrating an example of SP-CSI reporting for PUSCH repetition type B. If a UE is configured with PUSCH repetition type B, after the UE is activated to transmit SP-CSI reports on a PUSCH (e.g., by a base station via a CSI request field in an activation DCI 1302), the UE may be configured to expect / assume that for the first PUSCH 1304 after activation, the nominal repetition is the same as the effective repetition (e.g., no segmentation). Then, for a PUSCH 1306 carrying an SP-CSI report(s) without a corresponding PDCCH after activation (e.g., any PUSCH after the first PUSCH 1304), the nominal repetition may be omitted by the UE if the nominal repetition (e.g., the first nominal repetition) is not the same as the first effective repetition. For example, if a nominal repetition for the PUSCH 1306 contains an invalid symbol or crosses a slot boundary, the nominal repetition may be split into two effective repetitions, resulting in a nominal repetition not of the same length as the first effective repetition. Thus, the UE may be configured to omit the nominal repetition.
[0065]
[0093] In some examples, for single DCI (s-DCI) based multi-TRP PUSCH repetition types A and B, when a DCI schedules AP-CSI reporting for a UE and the DCI also indicates PUSCH repetitions associated with multiple TRPs, the UE may be configured to multiplex the AP-CSI report onto a first PUSCH repetition corresponding to a first beam (e.g., a UL / transmit beam) of the UE and multiplex the AP-CSI report onto an Xth PUSCH repetition corresponding to a second beam of the UE. In one example, for PUSCH repetition type A, the first PUSCH repetition may correspond to the second beam if X is equal to 1 (e.g., X=1).
[0066]
[0094] In another example, for PUSCH repetition type B, the first effective PUSCH repetition may be configured to correspond to a first beam, and the Xth effective repetition may be configured to correspond to a second beam. In such an example, the UE may not expect the first effective repetition corresponding to the first beam and the Xth effective repetition corresponding to the second beam to have a single symbol period. In addition, the UE may also expect the first effective repetition corresponding to the first beam and the Xth effective repetition corresponding to the second beam to have the same number of symbols. In some examples, X may be equal to 1 (e.g., X=1), or X may be equal to the first effective repetition corresponding to the second beam that includes the same number of symbols as the first effective repetition in the first beam.
[0067]
[0095] To improve the reliability and efficiency of multi-beam (or multi-TRP) PUSCH repetitions (i.e., transmission of PUSCH repetitions to different TRPs, panels, and / or antennas), the UE may be configured to transmit AP-CSI and / or SP-CSI in two or more PUSCH repetitions so that the CSI reports can benefit from multi-beam diversity. For example, by configuring the UE to transmit one or more CSI reports in different PUSCH repetitions associated with different transmit beams and / or transmit power parameters to different TRPs / panels / antennas of the base station, even if the link to one of the TRPs / panels / antennas is blocked, the one or more CSI reports may be received by the base station via the other TRPs / panels / antennas.
[0068]
[0096] 14 is a diagram 1400 illustrating an example of different UE configurations / behaviors for multiplexing one or more CSI reports onto a multi-beam (or multi-TRP) PUSCH repetition. In one example, a UE 1402 may be configured with four sets of PUSCH repetitions, which may include a first PUSCH repetition 1412, a second PUSCH repetition 1414, a third PUSCH repetition 1416, and a fourth PUSCH repetition 1418. The first PUSCH repetition 1412 and the second PUSCH repetition 1414 may belong to a first set of PUSCH repetitions 1408, which may be associated with a first SRS resource set (e.g., associated with a first transmit beam and / or a first transmit power parameter for transmission to a first TRP). The third PUSCH repetition 1416 and the fourth PUSCH repetition 1418 may belong to a second set of PUSCH repetitions 1410, which may be associated with a second SRS resource set (e.g., associated with a second transmit beam and / or a second transmit power parameter for transmission to a second TRP).
[0069]
[0097] In one example, the UE 1402 may be indicated or configured (e.g., by a base station or based on a preconfiguration) to apply a first behavior 1404 (e.g., a configuration or setting) or a second behavior 1406 with respect to how CSI reports are to be multiplexed into PUSCH repetitions. In the first behavior 1404 (e.g., behavior 1), the UE 1402 may multiplex one or more CSI reports (e.g., AP-CSI report or SP-CSI report) in a first (e.g., earliest) PUSCH repetition (e.g., a first PUSCH of a plurality of PUSCH repetitions). For example, in the first behavior 1404, the UE 1402 may multiplex one or more CSI reports in a first PUSCH repetition 1412 such that the UE 1402 may transmit one or more CSI reports to a first TRP based on a first transmit beam and / or a first transmit power parameter. In a second behavior 1406 (e.g., behavior 2), the UE 1402 may multiplex one or more CSI reports in a first (e.g., earliest) PUSCH repetition for the first SRS resource set (e.g., for the first transmit beam and / or the first transmit power parameter) and in a first (e.g., earliest) PUSCH repetition for the second SRS resource set (e.g., for the second transmit beam and / or the second transmit power parameter). For example, in the second behavior 1406, the UE 1402 may multiplex one or more CSI reports in the first PUSCH repetition 1412 such that the UE 1402 can transmit the one or more CSI reports to the first TRP based on the first transmit beam and / or the first transmit power parameter because the first PUSCH repetition 1412 is the first PUSCH repetition for the first SRS resource set.Because the third PUSCH repetition 1416 is the first PUSCH repetition for the second SRS resource set, the UE 1402 may also multiplex one or more CSI reports in the third PUSCH repetition 1416 such that the UE 1402 may transmit one or more CSI reports to a second TRP based on a second transmit beam and / or a second transmit power parameter.
[0070]
[0098] In one example, as shown at 1420, if the UE 1402 satisfies a first condition 1422 and a second condition 1424, the UE 1402 may be configured to apply the second behavior 1406, where the first condition 1422 may indicate that the number of symbols of the two effective PUSCH repetitions (e.g., in connection with PUSCH repetition type B) are identical and the second condition 1424 may indicate that UCI other than AP-CSI is not multiplexed in either of the two PUSCH repetitions. For example, to satisfy the first condition 1422 for applying the second behavior 1406, the number of symbols for the first PUSCH repetition 1412 and the third PUSCH repetition 1416 are equal. For example, to satisfy the second condition 1424 for applying the second behavior 1406, the first PUSCH repetition 1412 and the third PUSCH repetition 1416 are not multiplexed with UCI other than AP-CSI. If at least one of the first condition 1422 or the second condition 1424 is not satisfied, the UE 1402 may not be able to determine whether to multiplex one or more CSI reports, which PUSCH repetitions to multiplex with one or more CSI reports, etc.
[0071]
[0099] Because the first condition 1422 and / or the second condition 1424 may not be satisfied due to segmentation of the PUSCH repetition and other UCI other than CSI being multiplexed into the PUSCH repetition (e.g., for PUSCH repetition type B, where the effective repetition length may change after segmentation), aspects presented herein may enable the UE to determine whether to multiplex one or more CSI reports and / or which PUSCH repetitions to multiplex with one or more CSI reports when at least one of the first condition 1422 or the second condition 1424 is not satisfied.
[0072]
[0100] In one aspect of the disclosure, a UE may receive DCI scheduling multiple PUSCH repetitions, where the multiple PUSCH repetitions may include two sets of PUSCH repetitions, as described in connection with FIG. 14. The first set of PUSCH repetitions may be associated with a first SRS resource set (e.g., associated with a first UL beam and / or a first set of power control parameters) and the second set of PUSCH repetitions may be associated with a second SRS resource set (e.g., associated with a second UL beam and / or a second set of power control parameters). The two sets of PUSCH repetitions may correspond to different UL transmission parameters, such as different UL beams / different sets of power control parameters.
[0073]
[0101] If the DCI also requests the UE to provide an AP-CSI report (e.g., by way of a “CSI request” field in the DCI as described in connection with FIG. 9 ) and the UE is indicated / configured to multiplex the CSI report on one PUSCH repetition (e.g., the first PUSCH repetition) associated with the first SRS resource set and on one PUSCH repetition (e.g., the first PUSCH repetition) associated with the second SRS resource set (e.g., similar to the second behavior 1406), the UE may determine which of the two PUSCH repetitions to multiplex with the CSI report based at least in part on the number of symbols for the PUSCH repetition (e.g., effective repetition), the number of bits for the PUSCH repetition, the number of bits for the PUSCH repetition, the number of resource elements (REs) for the PUSCH repetition, and / or whether UCI other than CSI is multiplexed onto the PUSCH repetition, etc.
[0074]
[0102] In one aspect of the present disclosure, if the number of symbols in two PUSCH repetitions (e.g., effective PUSCH repetitions) is different (e.g., the first condition 1422 discussed in connection with FIG. 14 is not met), the UE may be configured not to multiplex AP-CSI into the effective PUSCH repetition with the smaller number of symbols.
[0075]
[0103] In another aspect of the disclosure, if UCI other than the AP-CSI is multiplexed onto one of the two PUSCH repetitions (e.g., the second condition 1424 discussed in connection with FIG. 14 is not met), the UE may be configured to not multiplex the AP-CSI onto the effective PUSCH repetition that has a larger number of bits of the other UCI. In another aspect of the disclosure, the UE may alternatively be configured to drop the other UCI in both PUSCH repetitions, and the UE may multiplex the AP-CSI onto both PUSCH repetitions.
[0076]
[0104] In another aspect of the present disclosure, if the number of symbols in two PUSCH repetitions (e.g., effective PUSCH repetitions) are different and UCI other than AP-CSI is multiplexed in one of the two PUSCH repetitions (e.g., both the first condition 1422 and the second condition 1424 discussed in connection with FIG. 14 are not satisfied), the UE may be configured to not multiplex the AP-CSI into the effective PUSCH repetition that has fewer available REs (which may exclude DMRS and other UCI).
[0077]
[0105] FIG. 15 is a communication flow 1500 between a UE and multiple TRPs of a base station according to an aspect of the disclosure. In one example, a UE 1502 communicates with a base station 1504 via a first TRP 1506 and a second TRP 1508 of the base station 1504. As such, the UE 1502 can transmit and receive data to the base station 1504 via at least one of the two TRPs. For example, the UE 1502 can receive data from or transmit data to the base station 1504, such as via the first TRP 1506, the second TRP 1508, or both the first TRP 1506 and the second TRP 1508. In some examples, the first TRP 1506 and the second TRP 1508 may be different antennas of the base station 1504. In other examples, the first TRP 1506 and the second TRP 1508 may be different panels (e.g., antenna panels) of the base station 1504. As described in connection with FIG. 1, in some aspects, a base station may include disaggregated components, such as a CU, one or more DUs, one or more RUs, one or more TRPs, one or more relays, one or more intelligent radio reflecting surfaces, and / or combinations thereof. Thus, for purposes of this disclosure, the term "base station" may include components of a base station. In some examples, the term "base station" may also be used interchangeably with the term "network entity" or "network node," which may refer to or include one or more disaggregated components of a base station.
[0078]
[0106] At 1510, the UE 1502 may receive a DCI 1512 from the base station 1504, such as via one of the first TRP 1506 or the second TRP 1508. The DCI 1512 may schedule multiple (or a set) of PUSCH repetitions including at least two sets of PUSCH repetitions, as described in connection with FIG. 14. For example, the UE 1502 may be configured with four sets of PUSCH repetitions, which may include a first PUSCH repetition 1514, a second PUSCH repetition 1516, a third PUSCH repetition 1518, and a fourth PUSCH repetition 1520. The first PUSCH repetition 1514 and the second PUSCH repetition 1516 may belong to a first set of PUSCH repetitions 1522, which may be associated with a first SRS resource set, e.g., a first transmit beam and / or a first set of power control parameters, for transmission to the first TRP 1506. The third PUSCH repetition 1518 and the fourth PUSCH repetition 1520 may belong to a second set of PUSCH repetitions 1524, which may be associated with a second SRS resource set, e.g., a second transmit beam and / or a second set of power control parameters, for transmission to the second TRP 1508. In this manner, the two sets of PUSCH repetitions 1522 and 1524 may correspond to different uplink transmission parameters, such as different transmit beams and / or different sets of power control parameters. In addition, the DCI 1512 may also request / indicate the UE 1502 to provide one or more AP-CSI reports 1526 (e.g., via a “CSI Request” field in the DCI as described in connection with FIG. 9).
[0079]
[0107] As indicated at 1528, the UE 1502 may also be indicated / configured (e.g., by the base station 1504 or preconfiguration, etc.) to multiplex one or more CSI reports, such as the AP-CSI report 1526, on one PUSCH repetition associated with the first SRS resource set (e.g., a PUSCH repetition from the first set of PUSCH repetitions 1522) and on one PUSCH repetition associated with the second SRS resource set (e.g., a PUSCH repetition from the second set of PUSCH repetitions 1524). In other words, the UE 1502 may be configured to apply the second behavior 1406 as described in connection with FIG. 14.
[0080]
[0108] At 1530, the UE 1502 may determine whether a PUSCH repetition of the first set of PUSCH repetitions 1522 and a PUSCH repetition of the second set of PUSCH repetitions 1524 have equal or different numbers of symbols. For example, the UE 1502 may determine whether a first PUSCH repetition (e.g., the first PUSCH repetition 1514) of the first set of PUSCH repetitions 1522 and a first PUSCH repetition (e.g., the third PUSCH repetition 1518) of the second set of PUSCH repetitions 1524 have the same (or different) number of symbols. In other words, the UE may determine whether the first PUSCH repetition 1514 and the third PUSCH repetition 1518 satisfy the first condition 1422 as described in connection with FIG. 14 . The UE 1502 may also determine whether UCI other than AP-CSI is multiplexed into one PUSCH repetition of the first set of PUSCH repetitions 1522 and one PUSCH repetition of the second set of PUSCH repetitions 1524. For example, the UE 1502 may determine whether UCI other than AP-CSI is multiplexed into one of the first PUSCH repetition 1514 and the third PUSCH repetition 1518. In other words, the UE may determine whether the first PUSCH repetition 1514 and the third PUSCH repetition 1518 satisfy the second condition 1424 as described in connection with FIG.
[0081]
[0109] At 1532, the UE 1502 may determine whether to multiplex one or more AP-CSI reports 1526 onto one PUSCH repetition of the first set of PUSCH repetitions 1522 and one PUSCH repetition of the second set of PUSCH repetitions 1524 (collectively “two PUSCH repetitions”) based on whether the first condition 1422 and / or the second condition 1424 are met (e.g., determined at 1530), further based on the number of symbols of the two PUSCH repetitions (e.g., effective repetitions), the number of bits of the two PUSCH repetitions, and / or the number of REs of the two PUSCH repetitions.
[0082]
[0110] In one example, as shown in option 1536 (e.g., option 1A), if the number of symbols in two PUSCH repetitions (e.g., effective PUSCH repetitions) is different (e.g., the first condition 1422 is not satisfied), the UE 1502 may be configured to not multiplex the AP-CSI into the effective PUSCH repetition with the fewer number of symbols. For example, if the two PUSCH repetitions include a first PUSCH repetition 1514 of a first set of PUSCH repetitions 1522 and a third PUSCH repetition 1518 of a second set of PUSCH repetitions 1524, where the first PUSCH repetition 1514 has a small / small number of symbols compared to the third PUSCH repetition 1518, the UE 1502 may be configured to avoid multiplexing one or more AP-CSI reports 1526 into the first PUSCH repetition 1514 and may multiplex the one or more AP-CSI reports 1526 into the third PUSCH repetition 1518. Then, at 1534, the UE 1502 may transmit the third PUSCH repetition 1518 multiplexed with the one or more AP-CSI reports 1526 to the second TRP 1508, as shown at 1546, based on a second transmit beam and / or a second set of power control parameters.
[0083]
[0111] In another example, as shown in option 1538 (e.g., option 1B), if UCI other than AP-CSI is multiplexed into one of the two PUSCH repetitions (e.g., the second condition 1424 is not satisfied), the UE 1502 may be configured to not multiplex the AP-CSI into an effective PUSCH repetition that has a larger number of bits for the other UCI. For example, if the two PUSCH repetitions include a first PUSCH repetition 1514 and a third PUSCH repetition 1518, where the first PUSCH repetition 1514 includes UCI that is not AP-CSI and has more bits than the UCI (e.g., UCI other than AP-CSI) in the third PUSCH repetition 1518, the UE 1502 may be configured to avoid multiplexing one or more AP-CSI reports 1526 into the first PUSCH repetition 1514 and may multiplex the one or more AP-CSI reports 1526 into the third PUSCH repetition 1518. Then, at 1534, the UE 1502 may transmit the third PUSCH repetition 1518 multiplexed with the one or more AP-CSI reports 1526 to the second TRP 1508 based on a second transmit beam and / or a second set of power control parameters, as shown at 1546. In another example, if the third PUSCH repetition 1518 includes non-AP-CSI UCI and the first PUSCH repetition 1514 does not include non-AP-CSI UCI, the third PUSCH repetition 1518 may have a greater number of bits of other UCI. As such, the UE 1502 may be configured to avoid multiplexing one or more AP-CSI reports 1526 into the third PUSCH repetition 1518 and may multiplex one or more AP-CSI reports 1526 into the first PUSCH repetition 1514. Then, at 1534, the UE 1502 may transmit the first PUSCH repetition 1514 multiplexed with the one or more AP-CSI reports 1526 to the first TRP 1506 based on the first transmit beam and / or the first set of power control parameters, as shown at 1544.
[0084]
[0112] In one example, as shown in option 1540 (e.g., option 1C), if the number of symbols in two PUSCH repetitions (e.g., effective PUSCH repetitions) are different (e.g., the first condition 1422 is not satisfied) and UCI other than AP-CSI is multiplexed into one of the two PUSCH repetitions (e.g., the second condition 1424 is not satisfied), the UE 1502 may be configured to not multiplex AP-CSI into the effective PUSCH repetition that has fewer available REs (excluding DMRS and other UCI). For example, the two PUSCH repetitions may include a first PUSCH repetition 1514 and a third PUSCH repetition 1518, where the first PUSCH repetition 1514 and the third PUSCH repetition 1518 do not have the same number of symbols (e.g., the first condition 1422 is not met) and at least one of the first PUSCH repetition 1514 and the third PUSCH repetition 1518 may include (e.g., be multiplexed with) UCI other than AP-CSI (e.g., the second condition 1424 is not met). If the first PUSCH repetition 1514 has fewer available REs compared to the third PUSCH repetition 1518, the UE 1502 may be configured to avoid multiplexing the one or more AP-CSI reports 1526 into the first PUSCH repetition 1514 and may multiplex the one or more AP-CSI reports 1526 into the third PUSCH repetition 1518. Then, at 1534, the UE 1502 may transmit the third PUSCH repetition 1518 multiplexed with the one or more AP-CSI reports 1526 to the second TRP 1508 based on a second transmit beam and / or a second set of power control parameters, as shown at 1546.
[0085]
[0113] In another example, as shown in option 1542 (e.g., option 2), if UCI other than AP-CSI is multiplexed into either of the two PUSCH repetitions (e.g., the second condition 1424 is not satisfied), the UE 1502 may be configured to drop the UCI other than AP-CSI, and the UE 1502 may multiplex AP-CSI into both PUSCH repetitions. For example, if the two PUSCH repetitions include a first PUSCH repetition 1514 and a third PUSCH repetition 1518, and one or both of the first PUSCH repetition 1514 and the third PUSCH repetition 1518 include UCI that is not AP-CSI, the UE 1502 may drop the UCI that is not AP-CSI from the first PUSCH repetition 1514 and / or the third PUSCH repetition 1518. The UE 1502 may then multiplex one or more AP-CSI reports onto both the first PUSCH repetition 1514 and the third PUSCH repetition 1518. Then, at 1534, the UE 1502 may transmit the first PUSCH repetition 1514 multiplexed with the one or more AP-CSI reports 1526 to the first TRP 1506 as shown at 1544 based on the first transmit beam and / or the first set of power control parameters, and the UE 1502 may also transmit the third PUSCH repetition 1518 multiplexed with the one or more AP-CSI reports 1526 to the second TRP 1508 as shown at 1546 based on the second transmit beam and / or the second set of power control parameters. It should be noted that a network entity (e.g., base station 1504) or a UE (e.g., UE 1502) may be configured to apply one or more of options 1536, 1538, 1540, or 1546, depending on the implementation.
[0086]
[0114] In another aspect of the disclosure, the UE may receive a DCI (e.g., DCI 1512) that schedules an AP-CSI report on a PUSCH that does not have a transport block (e.g., via a CSI request field of the DCI). In addition, two SRS resource sets corresponding to two sets of transmission parameters (e.g., two UL beams and / or two power control parameters, etc.) may be indicated to the UE, and the UE may be configured to apply the second behavior 1406. In one example, if both the first condition 1422 (e.g., the number of symbols of the two effective PUSCH repetitions are the same) and the second condition 1424 (e.g., UCI other than AP-CSI is not multiplexed on any of the two PUSCH repetitions) are not satisfied, the UE may assume that the number of repetitions is one, regardless of the number of indicated repetitions (e.g., the number of indicated repetitions that is not equal to one may be ignored). The UE may then be configured to transmit the AP-CSI report on one PUSCH repetition.
[0087]
[0115] In another example, if both the first condition 1422 and the second condition 1424 are not satisfied, the UE may assume the number of repetitions to be two regardless of the number of indicated repetitions (e.g., an indicated number of repetitions not equal to two may be ignored) and may be configured to apply one of the options 1536, 1538, 1540, or 1542 described in connection with FIG. 15. For example, as described in connection with option 1536 (e.g., option 1A), the UE 1502 may be configured to not multiplex AP-CSI into effective PUSCH repetitions with a smaller number of symbols. In another example, as described in connection with option 1538 (e.g., option 1B), the UE 1502 may be configured to not multiplex AP-CSI into effective PUSCH repetitions with a larger number of bits of other UCI. In another example, as described in connection with option 1540 (e.g., option 1C), the UE 1502 may be configured to not multiplex AP-CSI into an effective PUSCH repetition that has a smaller amount of available REs (excluding DMRS and other UCI). In another example, as described in connection with option 1542 (e.g., option 2), the UE 1502 may be configured to drop other UCI (e.g., UCI other than AP-CSI) in both PUSCH repetitions and multiplex AP-CSI into both PUSCH repetitions.
[0088]
[0116] In one example, in options 1536, 1538, and 1540 (e.g., options 1A, 1B, 1C), if the PUSCH repetition is not multiplexed with AP-CSI, the UE may be further configured to drop the entire PUSCH repetition (e.g., not transmit the PUSCH repetition), and which PUSCH repetition to drop may be up to options 1536, 1538, 1540, and 1542. For example, the UE may apply option 1536 (e.g., not multiplexing AP-CSI into an effective PUSCH repetition with a smaller number of symbols) to the first PUSCH repetition and the second PUSCH repetition. If the first PUSCH repetition has a smaller number of symbols compared to the second PUSCH repetition, the UE may multiplex AP-CSI into the second PUSCH repetition and the UE may drop the first PUSCH repetition. The UE may then transmit the second PUSCH repetition multiplexed with the AP-CSI report to the second TRP, such as based on the second transmit beam and / or the second set of power control parameters, as described in connection with FIG. 15. The entire PUSCH repetition may be dropped because the PUSCH is not accompanied by a TB. In another example, if the UE applies option 1542, the UE may drop other UCI in both PUSCH repetitions, and the UE may multiplex AP-CSI on both PUSCH repetitions. In some examples, the PUSCH without a TB may be indicated by setting the UL-SCH indicator of the DCI to zero.
[0089]
[0117] In another aspect of the disclosure, if the DCI activates SP-CSI reporting (e.g., a cyclic redundancy check (CRC) of the DCI is scrambled with the SP-CSI-RNTI), the UE may be configured to transmit two PUSCH repetitions (in each period) in each instance of an SP-CSI report in the PUSCH, in which case the UE may assume the number of repetitions to be two regardless of the number of indicated repetitions (e.g., an indicated number of repetitions not equal to two may be ignored). For example, the UE may transmit an SP-CSI report with both two PUSCH repetitions. This configuration differs from another configuration mentioned above in which each PUSCH may include only one PUSCH repetition and multiple repetitions (e.g., more than one PUSCH repetition) are not supported for SP-CSI reporting on the PUSCH (e.g., the UE assumes the number of repetitions to be one regardless of the value / parameter of numberofrepetitions configured for the UE).
[0090]
[0118] For PUSCH repetition type B, in one aspect of the present disclosure (e.g., selection 1), the UE may be configured to expect / assume that the first condition 1422 and the second condition 1424 are satisfied for the first PUSCH (e.g., the first PUSCH 1304 described in connection with FIG. 13) after DCI activation, where both the first and second nominal repetitions are the same as the first and second effective repetitions, respectively, for the first PUSCH after activation (so they have the same number of symbols), and there is no UCI other than the SP-CSI multiplexed on either of the two PUSCH repetitions. Then, for a PUSCH without a corresponding PDCCH after activation on the PUSCH by the CSI request field of the DCI (e.g., the PUSCH 1306 after the first PUSCH 1304 described in connection with FIG. 13), if the first condition 1422 and the second condition 1424 are not satisfied, the UE may apply at least one of the following selections:
[0091]
[0119] In one example (e.g., selection 1-1), the UE may apply one of options 1536, 1538, and 1540 (e.g., options 1A, 1B, and 1C) described in connection with FIG. 15, in which case the UE may be avoided from multiplexing the SP-CSI report into an effective PUSCH repetition with a smaller number of symbols, a larger number of bits of other UCI, or a smaller available RE, and the UE may omit the PUSCH repetition that is not multiplexed with the SP-CSI report (e.g., which repetition to omit is up to options 1536, 1538, and 1540). In other words, of the two PUSCH repetitions, the UE may be configured to multiplex the SP-CSI report into a PUSCH repetition with a larger number of symbols, a smaller number of bits of other UCI (or no other UCI), or a larger available RE, and the UE may omit the other PUSCH repetition that is not multiplexed with the SP-CSI report. In another example (eg, selection 1-2), the UE may be configured to drop UCI other than SP-CSI in both PUSCH repetitions, and the UE may multiplex the SP-CSI report in both PUSCH repetitions.
[0092]
[0120] In one aspect of the present disclosure (e.g., option 2-1), in PUSCH repetition type B, the UE may be configured not to distinguish between the first PUSCH after DCI activation (e.g., first PUSCH 1304) and other PUSCHs (e.g., PUSCH 1306 without a corresponding PDCCH). Then, if the first condition 1422 and the second condition 1424 are not satisfied for all PUSCH occasions, in one example (e.g., selection 2-1), the UE may apply one of the options 1536, 1538, and 1540 (e.g., options 1A, 1B, and 1C) described in connection with FIG. 15 , in which case the UE may be avoided from multiplexing the SP-CSI report into effective PUSCH repetitions that have a smaller number of symbols, a larger number of bits of other UCI, or fewer available REs, and the UE may omit PUSCH repetitions that are not multiplexed with the SP-CSI report (e.g., which repetitions to omit is up to options 1536, 1538, and 1540). In other words, of the two PUSCH repetitions, the UE may be configured to multiplex the SP-CSI report into the PUSCH repetition that has a larger number of symbols, a smaller number of bits of other UCI (or no other UCI), or a larger available RE, and the UE may omit the other PUSCH repetition that is not multiplexed with the SP-CSI report. In another example (e.g., selection 2-2), the UE may be configured to drop UCI other than SP-CSI in both PUSCH repetitions, and the UE may multiplex the SP-CSI report into both PUSCH repetitions.
[0093]
[0121] FIG. 16 is a communication flow 1600 between a UE and multiple TRPs of a base station according to an aspect of the disclosure. In one example, a UE 1602 may be communicating with a base station 1604 via a first TRP 1606 and a second TRP 1608 of the base station 1604. As such, the UE 1602 can transmit and receive data to the base station 1604 via at least one of the two TRPs. For example, the UE 1602 can receive data from or transmit data to the base station 1604 via the first TRP 1606, the second TRP 1608, or both the first TRP 1606 and the second TRP 1608. In some examples, the first TRP 1606 and the second TRP 1608 may be different antennas of the base station 1604. In other examples, the first TRP 1606 and the second TRP 1608 may be different panels (e.g., antenna panels) of the base station 1604. As described in connection with FIG. 1, in some aspects, a base station may include disaggregated components, such as a CU, one or more DUs, one or more RUs, one or more TRPs, one or more relays, one or more intelligent radio reflecting surfaces, and / or combinations thereof. Thus, for purposes of this disclosure, the term "base station" may include components of a base station. In some examples, the term "base station" may also be used interchangeably with the term "network entity" or "network node," which may refer to or include one or more disaggregated components of a base station.
[0094]
[0122] At 1610, the UE 1602 may receive a DCI 1612 from the base station 1604, such as via one of the first TRP 1606 or the second TRP 1608. The DCI 1612 may request / indicate the UE 1602 to provide an SP-CSI report 1626. For example, the CRC of the DCI 1610 may be scrambled with the SP-CSI-RNTI. In other words, the UE 1602 may be configured with SP-CSI reporting by the DCI 1612 as described in connection with FIG. 11, which may differ from the AP-CSI reporting described in connection with FIG. 9 and FIG. 15, where a DCI (e.g., DCI 1512) triggers AP-CSI reporting (or triggers CSI reporting on demand). Per the aspects described in connection with Figure 16, the UE 1602 may determine how to handle the first PUSCH after DCI activation. The UE 1602 may then determine how to multiplex the CSI reports onto the PUSCH repetitions, similar to the aspects described in connection with Figure 15 (e.g., for AP-CSI reporting). In addition, the DCI 1612 may also configure the UE 1602 to transmit two PUSCH repetitions, which may include a first PUSCH repetition 1614 and a second PUSCH repetition 1616, in each instance of a SP-CSI report on one PUSCH (e.g., per periodicity). In one example, the first PUSCH repetition 1614 may be associated with a first SRS resource set, e.g., associated with a first transmit beam and / or a first set of power control parameters for transmission to the first TRP 1606, and the second PUSCH repetition 1616 may be associated with a second SRS resource set, e.g., associated with a second transmit beam and / or a second set of power control parameters for transmission to the second TRP 1608. As such, the two PUSCH repetitions 1614 and 1616 may correspond to different uplink transmission parameters, such as different transmit beams and / or different sets of power control parameters.In another example, the UE 1602 may be configured to assume that the number of PUSCH repetitions is two regardless of the number of indicated repetitions (e.g., an indicated number of repetitions that is not equal to two may be ignored). Thus, the UE 1602 may transmit the SP-CSI report 1626 on both PUSCH repetitions.
[0095]
[0123] As indicated at 1628, the UE 1602 may also be indicated / configured (e.g., by the base station 1604 or preconfiguration, etc.) to multiplex one or more CSI reports, such as the SP-CSI report 1626, on a PUSCH repetition associated with the first SRS resource set (e.g., the first PUSCH repetition 1614) and on a PUSCH repetition associated with the second SRS resource set (e.g., the second PUSCH repetition 1616). In other words, the UE 1602 may be configured to apply the second behavior 1406 as described in connection with FIG. 14.
[0096]
[0124] At 1630, the UE 1602 may determine whether the number of symbols of the first PUSCH repetition 1614 and the second PUSCH repetition 1616 are equal. In other words, the UE may determine whether the first PUSCH repetition 1614 and the second PUSCH repetition 1616 satisfy the first condition 1422 as described in connection with FIG. 14. The UE 1602 may also determine whether UCI other than SP-CSI is multiplexed into either the first PUSCH repetition 1614 or the second PUSCH repetition 1616. In other words, the UE may determine whether the first PUSCH repetition 1614 and the second PUSCH repetition 1616 satisfy the second condition 1424 as described in connection with FIG. 14.
[0097]
[0125] In 1632, the UE 1602 may determine whether to multiplex the SP-CSI report 1626 into the first PUSCH repetition 1614 and / or the second PUSCH repetition 1616 (collectively the “two PUSCH repetitions”) based on whether the first condition 1422 and / or the second condition 1424 are met (e.g., determined in 1630), further based on the number of symbols for the two PUSCH repetitions (e.g., effective repetitions), the number of bits in the two PUSCH repetitions, and / or the number of REs in the two PUSCH repetitions, etc. (e.g., options 1536, 1538, 1540, and 1542).
[0098]
[0126] At 1634, the UE 1602 may transmit the first PUSCH repetition 1614 and / or the second PUSCH repetition 1616 multiplexed with the SP-CSI report 1626 to the first TRP 1606 and / or the second TRP 1608 based on the determination as shown at 1644 and / or 1646, respectively.
[0099]
[0127] In one example, for PUSCH repetition type B, the UE 1602 may be configured to apply a first selection 1648, in which case the UE 1602 may be configured to expect / assume that the first condition 1422 and the second condition 1424 are satisfied for a first PUSCH (e.g., the first PUSCH 1304 described in connection with FIG. 13) after DCI activation, where both the first and second nominal repetitions are the same as the first and second effective repetitions, respectively, for the first PUSCH after activation (e.g., the first PUSCH repetition 1614 and the second PUSCH repetition 1616 have the same number of symbols), and there is no UCI other than SP-CSI multiplexed onto either of the two PUSCH repetitions. Then, for a PUSCH without a corresponding PDCCH after being activated on the PUSCH by the CSI request field of the DCI (e.g., for the PUSCH 1306 after the first PUSCH 1304 described in connection with FIG. 13), if the first condition 1422 and / or the second condition 1424 are not satisfied, in one example (e.g., selection 1650), the UE 1602 may select options 1536, 1538, and 1540 (e.g., options 1A, 1B, and 1C) described in connection with FIG. 15. and 1C) may be applied, in which case the UE 1602 may be avoided from multiplexing the SP-CSI report into an effective PUSCH repetition with a smaller number of symbols, a larger number of bits of other UCI, or a smaller available RE, and the UE 1602 may omit the PUSCH repetition that is not multiplexed with the SP-CSI report 1626 (e.g., which repetition to omit is up to the options 1536, 1538, and 1540). In other words, of the two PUSCH repetitions, the UE 1602 may be configured to multiplex the SP-CSI report 1626 into a PUSCH repetition with a larger number of symbols, a smaller number of bits of other UCI (or no other UCI), or a larger available RE, and the UE may omit the other PUSCH repetition that is not multiplexed with the SP-CSI report.In another example (eg, selection 1652), the UE 1602 may be configured to drop UCI other than SP-CSI in both PUSCH repetitions, and the UE 1602 may multiplex the SP-CSI report 1626 in both PUSCH repetitions.
[0100]
[0128] 17 is a diagram 1700 illustrating an example of multiplexing SP-CSI reports (e.g., based on a first selection 1648) according to an aspect of the disclosure, where the UE 1602 may expect / assume that the first condition 1422 and the second condition 1424 are satisfied for a first PUSCH repetition (e.g., the first PUSCH repetition and the second PUSCH repetition 1616) after DCI activation (e.g., activated by the DCI 1612), which may otherwise be an error case. Then, for a PUSCH repetition without a corresponding PDCCH, the UE 1602 may determine a PUSCH repetition (e.g., the first PUSCH repetition 1614 and / or the second PUSCH repetition 1616) on which to multiplex the SP-CSI report 1626 based on the options 1536, 1538, 1540, and 1542. For example, in a given SP-CSI reporting occasion (e.g., in a period), if conditions 1422 and / or 1424 are not satisfied, the UE 1602 may multiplex the SP-CSI report 1626 onto one of the PUSCH repetitions and omit it from another of the PUSCH repetitions. However, if both conditions 1422 and / or 1424 are satisfied, the UE 1602 may multiplex the SP-CSI report 1626 onto both PUSCH repetitions.
[0101]
[0129] Referring back to FIG. 16, in another example, for PUSCH repetition type B, the UE 1602 may be configured to apply a second selection 1654, in which case the UE 1602 may be configured not to distinguish between a first PUSCH after DCI activation (e.g., the first PUSCH 1304 as described in connection with FIG. 13) and a PUSCH without a corresponding PDCCH (e.g., the PUSCH 1306 after the first PUSCH 1304 as described in connection with FIG. 13). Then, if the first condition 1422 and / or the second condition 1424 are not satisfied for all PUSCH occasions, then, in one example (e.g., selection 1656), the UE 1602 may apply one of the options 1536, 1538, and 1540 (e.g., options 1A, 1B, and 1C) described in connection with FIG. 15, in which case the UE 1602 may be avoided from multiplexing the SP-CSI report into effective PUSCH repetitions that have a smaller number of symbols, a larger number of bits of other UCI, or fewer available REs, and the UE 1602 may omit PUSCH repetitions that are not multiplexed with the SP-CSI report 1626 (e.g., which repetitions to omit is up to the options 1536, 1538, and 1540). In other words, of the two PUSCH repetitions, the UE 1602 may be configured to multiplex the SP-CSI report 1626 into the PUSCH repetition that has a larger number of symbols, a smaller number of bits of other UCI (or no other UCI), or a larger available RE, and the UE may omit the other PUSCH repetition that is not multiplexed with the SP-CSI report. In another example (e.g., selection 1658), the UE 1602 may be configured to drop UCI other than SP-CSI in both PUSCH repetitions, and the UE 1602 may multiplex the SP-CSI report 1626 into both PUSCH repetitions.
[0102]
[0130] 18 is a diagram 1800 illustrating an example of multiplexing SP-CSI reports (e.g., based on the second selection 1654) according to an aspect of the disclosure, where the UE 1602 may be configured to not distinguish between a first PUSCH after DCI activation (e.g., the first PUSCH 1304 as described in connection with FIG. 13) and a PUSCH without a corresponding PDCCH (e.g., the PUSCH 1306 after the first PUSCH 1304 as described in connection with FIG. 13). Then, for every PUSCH occasion, the UE 1602 may determine the PUSCH repetition (e.g., the first PUSCH repetition 1614 and / or the second PUSCH repetition 1616) on which to multiplex the SP-CSI report 1626 based on the options 1536, 1538, 1540, and 1542. For example, in a given SP-CSI reporting occasion (e.g., in a period), if the conditions 1422 and / or 1424 are not satisfied, the UE 1602 may multiplex the SP-CSI report 1626 onto one of the PUSCH repetitions and omit the other PUSCH repetition. However, if both the conditions 1422 and / or 1424 are satisfied, the UE 1602 may multiplex the SP-CSI report 1626 onto both PUSCH repetitions. The aspects described in connection with FIG. 17 and FIG. 18 allow the UE to multiplex the SP-CSI report in a more predictive manner such that the base station can determine whether a transmission from the UE includes a CSI report. As such, the UE may be configured to apply either the selection 1648 or the selection 1654 depending on the implementation.
[0103]
[0131] 19-26 are flowcharts 1900, 2000, 2100, 2200, 2300, 2400, 2500, and 2600 illustrating various aspects of a method of wireless communication, respectively. The method may be performed by a UE or a component of a UE (e.g., a processing system that may include the UE 104, 1402, 1502, 1602, the device 2702, the memory 360, and may be the UE as a whole 350 or a component of the UE 350, such as the TX processor 368, the RX processor 356, and / or the controller / processor 359). The method enables the UE to determine whether to multiplex one or more CSI reports into a PUSCH repetition and / or into which PUSCH repetition to multiplex one or more CSI reports for multi-TRP PUSCH repetitions.
[0104]
[0132] At 1902, the UE may receive a DCI scheduling a plurality of PUSCH repetitions, including a first set of PUSCH repetitions associated with a first SRS set and a second set of PUSCH repetitions associated with a second SRS set, as described in connection with Figures 15 and 16. For example, at 1510, the UE 1502 may receive a DCI 1512 scheduling a plurality of PUSCH repetitions, including a first set of PUSCH repetitions 1522 associated with a first SRS set and a second set of PUSCH repetitions 1524 associated with a second SRS set, requesting transmission of at least one CSI report 1526 to be multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions. Reception of the DCI may be performed, for example, by the DCI processing component 2740 and / or the receiving component 2730 of the apparatus 2702 in FIG. 27. In one example, the DCI may request transmission of at least one AP-CSI report as described in connection with FIG. 15. In another example, the DCI may request transmission of an SP-CSI report as described in connection with FIG. 16. In another example, the DCI may request transmission of at least one CSI report to be multiplexed on one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions.
[0105]
[0133] In 1904, the UE may determine whether to multiplex the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on at least one of: whether a number of symbols differs in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions, or whether UCI excluding the at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions, as described in connection with FIG. 15 and FIG. 16 . For example, at 1530, the UE 1502 may determine whether a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions (e.g., whether the first condition 1422 is met) or whether UCI excluding at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions. 27 , may determine whether to multiplex the at least one CSI report 1526 onto one PUSCH repetition of the first set of PUSCH repetitions 1522, onto one PUSCH repetition of the second set of PUSCH repetitions 1524, or onto both one PUSCH repetition of the first set of PUSCH repetitions 1522 and one PUSCH repetition of the second set of PUSCH repetitions 1524. The determination of whether to multiplex the at least one CSI report may be performed, for example, by a CSI report determination component 2742 of the apparatus 2702 in FIG. 27 .
[0106]
[0134] At 1906, the UE may transmit the at least one CSI report multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions, based on the determination, as described in connection with Figures 15 and 16. For example, at 1534, the UE 1502 may transmit the at least one CSI report 1526 multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions 1522, one PUSCH repetition of the second set of PUSCH repetitions 1524, or both one PUSCH repetition of the first set of PUSCH repetitions 1522 and one PUSCH repetition of the second set of PUSCH repetitions 1524, based on the determination. The transmission of the at least one CSI report may be performed, for example, by the CSI report process component 2744 and / or the transmission component 2734 of the apparatus 2702 in FIG.
[0107]
[0135] In one example, as shown by flowchart 2000 in FIG. 20, the UE may determine 2002 that a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions (e.g., the first condition 1422 is not met). In such an example, the UE may multiplex and transmit at least one CSI report in one of the one PUSCH repetition of the first set of PUSCH repetitions or the one PUSCH repetition of the second set of PUSCH repetitions based on which of the one PUSCH repetition of the first and second sets of PUSCH repetitions has a greater number of symbols, in 2004. In such an example, in 2006, the UE may avoid multiplexing one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions with the other, as described in connection with option 1536 of Figure 15. In such an example, as described in connection with Figures 16-18, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with a periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within an i-th PUSCH occasion of the x distinct PUSCH occasions, where i>=2 (e.g., in selection 1648) or i>=1 (e.g., in selection 1654). 17, if there are x PUSCH occasions, the UE (e.g., UE 1602) may be configured to expect / assume that the first condition 1422 and the second condition 1424 are satisfied on the first PUSCH occasion (e.g., on PUSCH repetition with i=1) after DCI activation. Then on a subsequent PUSCH (e.g., on PUSCH repetition with i>=2, such as i=2, 3, 4, ..., x), the UE may multiplex the CSI report onto the subsequent PUSCH based on options 1536, 1538, 1540, and 1542.On the other hand, in the second selection 1654 described in relation to FIG. 18, if there are x PUSCH occasions, the UE does not expect / assume that the first condition 1422 and the second condition 1424 are satisfied on the first PUSCH occasion after DCI activation (e.g., on PUSCH repetition with i=1). In other words, the UE does not distinguish between the first PUSCH after DCI activation and other PUSCHs. Therefore, for all PUSCHs (e.g., on PUSCH repetitions with i>=1, such as i=2, 3, 4, ..., x), the UE may multiplex the CSI report onto all PUSCHs based on the options 1536, 1538, 1540, and 1542.
[0108]
[0136] For example, if it is determined that the number of symbols of one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of symbols of one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of symbols of one PUSCH repetition of the first set of PUSCH repetitions is less than the number of symbols of one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions.
[0109]
[0137] In another example, as shown by flowchart 2100 in FIG. 21 , the UE may determine 2102 that the UCI, excluding the at least one CSI report, will be multiplexed into at least one of a PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, the UE may determine 2104 that a number of bits of UCI for multiplexing in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions are different. In such an example, the UE may multiplex and transmit the at least one CSI report onto one of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on which of the one PUSCH repetition of the first set of PUSCH repetitions and the one PUSCH repetition of the second set of PUSCH repetitions has fewer UCI bits for multiplexing, at 2106. In such an example, the UE may avoid multiplexing onto the other of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions, as described in connection with option 1538 of FIG.
[0110]
[0138] For example, if it is determined that the number of UCI bits for multiplexing in one PUSCH repetition of the first set of PUSCH repetitions is less than the number of UCI bits for multiplexing in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of UCI bits for multiplexing in one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of UCI bits for multiplexing in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report in one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions.
[0111]
[0139] In another example, as shown by flowchart 2200 in FIG. 22, the UE may determine 2202 that a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions (e.g., the first condition 1422 is not met). In such an example, the UE may determine 2204 that UCI excluding the at least one CSI report will be multiplexed into at least one of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, at 2206, the UE may multiplex and transmit the at least one CSI report onto one of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on whether one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a larger number of REs available for transmission. In such an example, at 2208, the UE may avoid multiplexing the other of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions, as described in connection with option 1540 of FIG. 15 . In such an example, as described in connection with Figures 16-18, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with a periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within an i-th PUSCH occasion of the x distinct PUSCH occasions, where i >= 2 (e.g., in selection 1648) or i >= 1 (e.g., in selection 1654).
[0112]
[0140] For example, if it is determined that the number of REs available for transmission in one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of REs available for transmission in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report onto the one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto the one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of REs available for transmission in one PUSCH repetition of the first set of PUSCH repetitions is less than the number of REs available for transmission in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions.
[0113]
[0141] In another example, as illustrated by flowchart 2300 in FIG. 23, the UE may determine 2302 that the UCI excluding the at least one CSI report will be multiplexed into at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, the UE may transmit 2304 multiplexed the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions without the multiplexed UCI if the UCI is multiplexed into one PUSCH repetition of the first set of PUSCH repetitions. In such an example, in 2306, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions without multiplexed UCI if the UCI is multiplexed onto one PUSCH repetition of the second set of PUSCH repetitions, as described in connection with option 1542 of FIG. 15. In such an example, as described in connection with FIG. 16-18, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with a periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within an i-th PUSCH occasion of the x distinct PUSCH occasions, where i>=2 (e.g., in selection 1648) or i>=1 (e.g., in selection 1654).
[0114]
[0142] In another example, as illustrated by the flowchart 2400 in FIG. 24, at 2402, the UE may determine that the number of symbols in one PUSCH repetition of the first set of PUSCH repetitions is different from the number of symbols in one PUSCH repetition of the second set of PUSCH repetitions (e.g., the first condition 1422 is not met). In such an example, at 2404, the UE may determine that the UCI excluding the at least one CSI report will be multiplexed in at least one of the PUSCH repetition of the first set of PUSCH repetitions or the PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, at 2406, the UE may determine that the UE does not have a TB to transmit in the PUSCH repetition. In such an example, at 2408, the UE may transmit at least one CSI in one PUSCH repetition of the first set of PUSCH repetitions. In such an example, at 2410, the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions.
[0115]
[0143] In another example, as illustrated by flowchart 2500 in FIG. 25, the UE may determine 2502 that the number of symbols in one PUSCH repetition of the first set of PUSCH repetitions is different from the number of symbols in one PUSCH repetition of the second set of PUSCH repetitions (e.g., the first condition 1422 is not met). In such an example, the UE may determine 2504 that the UCI excluding the at least one CSI report will be multiplexed into at least one of the PUSCH repetition of the first set of PUSCH repetitions or the PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, the UE may determine 2506 that the UE does not have a TB to transmit in the PUSCH repetition. In such an example, at 2508, the UE may multiplex and transmit the at least one CSI report onto one of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on at least one of: which one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a larger number of symbols, which one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a smaller number of UCI bits for multiplexing, or which one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a larger number of REs available for transmission. In such an example, at 2510, the UE may avoid multiplexing one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions with the other.
[0116]
[0144] In another example, as illustrated by flowchart 2600 in FIG. 26, the UE may determine 2602 that the number of symbols in one PUSCH repetition of the first set of PUSCH repetitions is different from the number of symbols in one PUSCH repetition of the second set of PUSCH repetitions (e.g., the first condition 1422 is not met). In such an example, the UE may determine 2604 that the UCI excluding the at least one CSI report will be multiplexed into at least one of the PUSCH repetition of the first set of PUSCH repetitions or the PUSCH repetition of the second set of PUSCH repetitions (e.g., the second condition 1424 is not met). In such an example, the UE may determine 2606 that the UE does not have a TB to transmit in the PUSCH repetition. In such an example, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions without multiplexed UCI if UCI is multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions, at 2608. In such an example, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions without multiplexed UCI if UCI is multiplexed onto one PUSCH repetition of the second set of PUSCH repetitions, at 2610.
[0117]
[0145] 27 is a diagram 2700 illustrating an example of a hardware implementation for an apparatus 2702. The apparatus 2702 is a UE and includes a cellular baseband processor 2704 (also referred to as a modem) coupled to a cellular RF transceiver 2722 and one or more subscriber identity module (SIM) cards 2720, an application processor 2706 coupled to a secure digital (SD) card 2708 and a screen 2710, a Bluetooth module 2712, a wireless local area network (WLAN) module 2714, a global positioning system (GPS) module 2716, and a power source 2718. The cellular baseband processor 2704 communicates with the UE 104 and / or the BS 102 / 180 through the cellular RF transceiver 2722. The cellular baseband processor 2704 may include a computer-readable medium / memory. The computer-readable medium / memory may be non-transitory. The cellular baseband processor 2704 is responsible for general processing, including the execution of software stored in a computer-readable medium / memory. The software, when executed by the cellular baseband processor 2704, causes the cellular baseband processor 2704 to perform the various functions described above. The computer-readable medium / memory may also be used to store data that is manipulated by the cellular baseband processor 2704 when executing the software. The cellular baseband processor 2704 further includes a receiving component 2730, a communications manager 2732, and a transmitting component 2734. The communications manager 2732 includes one or more of the illustrated components. The components in the communications manager 2732 may be stored in a computer-readable medium / memory and / or configured as hardware in the cellular baseband processor 2704. The cellular baseband processor 2704 may be a component of the UE 350 and may include the memory 360 and / or at least one of the TX processor 368, the RX processor 356, and the controller / processor 359.In one configuration, the device 2702 may be a modem chip and include only the baseband processor 2704, while in another configuration, the device 2702 may be an entire UE (eg, see 350 in FIG. 3) and include additional modules of the device 2702.
[0118]
[0146] The communications manager 2732 includes a first set of PUSCH repetitions associated with a first SRS set and a second set of PUSCH repetitions associated with a second SRS set, e.g., as described in connection with 1902 of FIG. 19 , and includes a DCI processing component 2740 configured to receive DCI scheduling a plurality of PUSCH repetitions requesting transmission of at least one CSI report to be multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions. The communications manager 2732 further includes a CSI report determination component 2742 configured to determine whether to multiplex the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on at least one of: whether a number of symbols differs between one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions, or whether UCI excluding the at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions, e.g., as described in connection with 1904 of FIG. 19 . The communications manager 2732 further includes a CSI report process component 2744 configured to multiplex and transmit the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on the determination, e.g., as described in connection with 1906 of FIG. 19 .
[0119]
[0147] The apparatus may include additional components that perform each of the blocks of the algorithms in the flowcharts of Figures 19-26. Thus, each block in the flowcharts of Figures 19-26 may be performed by one component, and the apparatus may include one or more of those components. The components may be one or more hardware components specifically configured to perform the described processes / algorithms, implemented by a processor configured to perform the described processes / algorithms, stored in a computer-readable medium for implementation by a processor, or some combination thereof.
[0120]
[0148] In one configuration, the apparatus 2702, and in particular the cellular baseband processor 2704, includes a first set of PUSCH repetitions associated with a first SRS set and a second set of PUSCH repetitions associated with a second SRS set, and includes means for receiving DCI scheduling a plurality of PUSCH repetitions requesting transmission of at least one CSI report to be multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions (e.g., DCI processing component 2740 and / or receiving component 2730). The apparatus 2702 includes means for determining whether to multiplex the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on at least one of whether a number of symbols differs between one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions, or whether UCI excluding the at least one CSI report is to be transmitted in one PUSCH repetition of the first set of PUSCH repetitions or in one PUSCH repetition of the second set of PUSCH repetitions (e.g., a CSI report determination component 2742). The apparatus 2702 includes means for multiplexing and transmitting the at least one CSI report on one PUSCH repetition of the first set of PUSCH repetitions, one PUSCH repetition of the second set of PUSCH repetitions, or both one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions based on the determination (e.g., the CSI report process component 2744 and / or the transmission component 2734). In one configuration, the DCI may request transmission of the at least one AP-CSI report.In another configuration, the DCI may request transmission of the SP-CSI report.
[0121]
[0149] In one configuration, the apparatus 2702 may determine that a number of symbols is different between one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report into one of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on which of the one PUSCH repetition of the first and second sets of PUSCH repetitions has a larger number of symbols. In such configuration, the apparatus 2702 may include means for avoiding multiplexing the other of the one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such a configuration, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within the i-th PUSCH occasion of the x distinct PUSCH occasions, where i>=2 or i>=1.
[0122]
[0150] For example, if it is determined that the number of symbols of one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of symbols of one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of symbols of one PUSCH repetition of the first set of PUSCH repetitions is less than the number of symbols of one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions.
[0123]
[0151] In another configuration, the apparatus 2702 may determine that the UCI excluding the at least one CSI report is to be multiplexed into at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may determine that a number of bits of UCI for multiplexing is different between one PUSCH repetition of the first set of PUSCH repetitions and one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on whether one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a smaller number of bits of UCI for multiplexing. In such a configuration, the apparatus 2702 may include means for avoiding multiplexing one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions with another.
[0124]
[0152] For example, if it is determined that the number of UCI bits for multiplexing in one PUSCH repetition of the first set of PUSCH repetitions is less than the number of UCI bits for multiplexing in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report in one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of UCI bits for multiplexing in one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of UCI bits for multiplexing in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report in one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report in one PUSCH repetition of the first set of PUSCH repetitions.
[0125]
[0153] In another configuration, the apparatus 2702 may determine that a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may determine that the UCI excluding the at least one CSI report will be multiplexed into at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report into one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on whether one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions has a larger number of REs available for transmission. In such a configuration, the apparatus 2702 may include means for avoiding multiplexing one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions with the other. In such a configuration, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with a periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within an i-th PUSCH occasion of the x distinct PUSCH occasions, where i>=2 or i>=1.
[0126]
[0154] For example, if it is determined that the number of REs available for transmission in one PUSCH repetition of the first set of PUSCH repetitions is greater than the number of REs available for transmission in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report onto the one PUSCH repetition of the first set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto the one PUSCH repetition of the second set of PUSCH repetitions. On the other hand, if it is determined that the number of REs available for transmission in one PUSCH repetition of the first set of PUSCH repetitions is less than the number of REs available for transmission in one PUSCH repetition of the second set of PUSCH repetitions, the UE may multiplex and transmit the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions, and the UE may avoid multiplexing the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions.
[0127]
[0155] In another configuration, the apparatus 2702 may determine that the UCI, excluding the at least one CSI report, is to be multiplexed onto at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions without the multiplexed UCI if the UCI is multiplexed onto one PUSCH repetition of the first set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report onto one PUSCH repetition of the second set of PUSCH repetitions without the multiplexed UCI if the UCI is multiplexed onto one PUSCH repetition of the second set of PUSCH repetitions. In such a configuration, if the scheduled PUSCH repetitions include x distinct PUSCH occasions with periodicity P, the first set of PUSCH repetitions and the second set of PUSCH repetitions may be within the i-th PUSCH occasion of the x distinct PUSCH occasions, where i>=2 or i>=1.
[0128]
[0156] In another configuration, the apparatus 2702 may determine that a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may determine that the UCI, excluding the at least one CSI report, will be multiplexed in at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for determining that the UE does not have a TB to transmit in a PUSCH repetition. In another configuration, the apparatus 2702 may include means for transmitting at least one CSI in one PUSCH repetition of the first set of PUSCH repetitions. In another configuration, the apparatus 2702 may include means for avoiding multiplexing the at least one CSI report in one PUSCH repetition of the second set of PUSCH repetitions.
[0129]
[0157] In another configuration, the apparatus 2702 may determine that a number of symbols is different in one PUSCH repetition of the first set of PUSCH repetitions and in one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may determine that the UCI excluding the at least one CSI report will be multiplexed into at least one of one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions. In such configuration, the apparatus 2702 may include means for determining that the UE does not have a TB to transmit in the PUSCH repetition. In such a configuration, the apparatus 2702 may include means for multiplexing and transmitting the at least one CSI report onto one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions based on at least one of: whether the one PUSCH repetition of the first set of PUSCH repetitions or the one PUSCH repetition of the second set of PUSCH repetitions has a larger number of symbols, whether the one PUSCH repetition of the first set of PUSCH repetitions or the one PUSCH repetition of the second set of PUSCH repetitions has a smaller number of UCI bits for multiplexing, or whether the one PUSCH repetition of the first set of PUSCH repetitions or the one PUSCH repetition of the second set of PUSCH repetitions has a larger number of REs available for transmission. In such a configuration, the apparatus 2702 may include means for avoiding multiplexing one PUSCH repetition of the first set of PUSCH repetitions or one PUSCH repetition of the second set of PUSCH repetitions with another.
[0130]

Terms such as "if," "when," and "while" should be construed to mean "under the condition that," rather than implying an immediate time relationship or reaction. That is, these phrases, for example, "when," do not imply an immediate action in response to or during the occurrence of an action, but merely imply that if a condition is met, an action occurs, but does not require a specific or immediate time constraint for the action to occur. The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects. Unless otherwise specified, the term "some" refers to one or more. Combinations such as "at least one of A, B, or C," "one or more of A, B, or C," "at least one of A, B, and C," "one or more of A, B, and C," and "A, B, C, or any combination thereof" include any combination of A, B, and / or C, and may include multiple As, multiple Bs, or multiple Cs.Specifically, combinations such as "at least one of A, B, or C," "one or more of A, B, or C," "at least one of A, B, and C," "one or more of A, B, and C," and "A, B, C, or any combination thereof" may be A only, B only, C only, A and B, A and C, B and C, or A and B and C, where any such combination may include one or more members of A, B, or C.

Moreover, nothing disclosed herein is made public, regardless of whether such disclosure is expressly recited in the claims. The words "module," "mechanism," "element," "device," and the like may not be substitutes for the word "means." Therefore, no claim element should be construed as a means-plus-function unless the element is expressly recited using the phrase "means for."
