Semi-persistent reporting of channel status information

Abstract

We provide methods, systems, and devices for wireless communication. [Solution] In some wireless communication systems, a user device (UE) may receive downlink control information (DCI) from a base station that activates periodic channel status information (CSI) reporting via uplink shared channel transmissions (e.g., via physical uplink shared channel (PUSCH) transmissions). The UE may then identify trigger conditions that trigger the transmission of both a first instance of the CSI report and a second instance of the CSI report within one period of the periodic CSI report. Based on the satisfaction of the trigger conditions, the UE may transmit a first instance of the CSI report via a first uplink shared channel transmission and a second instance of the CSI report via a second uplink shared channel transmission, both uplink shared channel transmissions within one period of the periodic CSI report.

[0001] Cross-reference This patent application claims priority to U.S. Patent Application No. 17 / 538,851, entitled "SEMIPERSISTENT REPORTING OF CHANNEL STATE INFORMATION" by Khoshnevisan et al., filed on Nov. 30, 2021, and U.S. Provisional Patent Application No. 63 / 131,287, entitled "SEMIPERSISTENT REPORTING OF CHANNEL STATE INFORMATION" by Khoshnevisan et al., filed on Dec. 28, 2020, each of which has been assigned to the assignee of this application.

[0002] The following relates to wireless communication including semi-persistent reporting of channel state information.

Background Art

[0003] Wireless communication systems are widely deployed to provide various types of communication content, including voice, video, packet data, messaging, and broadcast. These systems may support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems such as Long-Term Evolution (LTE) systems, LTE-A systems, or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may sometimes be known as user equipment (UEs).

[0004] Some wireless communication systems may support communication using one or more antenna arrays in different devices. For example, a network may communicate with an UE using one or more transmit / receive points (TRPs), and each TRP and UE may have one or more antenna arrays to form a directional beam. Efficient communication between the UE and one or more TRPs helps improve the network's throughput, latency, and reliability, and therefore, techniques to further improve efficient communication are desirable. [Overview of the project] [Means for solving the problem]

[0005] The techniques described relate to improved methods, systems, devices, and apparatus for supporting semi-persistent reporting of channel status information. Various embodiments provide techniques for communication between user equipment (UE) and a base station, where the UE may transmit multiple iterations of uplink communication by different transmit beams to increase the likelihood of successful reception of the uplink communication. For example, a base station may transmit signaling to activate periodic channel status information (CSI) reporting, and the UE may identify trigger conditions that trigger both a first instance of CSI reporting and a second instance of CSI reporting within one period of periodic CSI reporting. The UE may then transmit a first instance of CSI reporting via a first uplink shared channel transmit (e.g., via a first physical uplink shared channel (PUSCH) transmit) and a second instance of CSI reporting via a second uplink shared channel transmit (e.g., via a second PUSCH transmit) during a single period of periodic CSI reporting. Transmitting multiple instances of a CSI report can increase the reliability of the CSI report compared to a single instance of CSI report transmission. In addition, a UE may transmit first and second instances of a CSI report using different sets of sounding reference signals (SRS) resources (e.g., each associated with a different transmit beam). Transmitting multiple instances of a CSI report using both a first and a second SRS resource set can further improve the reliability of the CSI report compared to a CSI report utilizing a single SRS resource set.

[0006] A method for wireless communication in a UE is described. The method may include the steps of: receiving downlink control information (DCI) from a base station that activates periodic CSI reporting via uplink shared channel transmission; identifying trigger conditions that trigger the transmission of both a first instance of CSI reporting and a second instance of CSI reporting within one period of periodic CSI reporting; and transmitting the first instance of CSI reporting via a first uplink shared channel transmission and the second instance of CSI reporting via a second uplink shared channel transmission based on the satisfaction of the trigger conditions, wherein both the first and second uplink shared channel transmissions fall within one period of periodic CSI reporting.

[0038] In some wireless communication systems, user equipment (UE) may communicate with a base station using multiple iterations of uplink communication (possibly via different transmit beams) to increase the likelihood of successful reception of the uplink communication. For example, a base station may transmit a signaling that activates periodic channel status information (CSI) reporting, and the UE may identify trigger conditions that trigger both a first instance and a second instance of the CSI reporting within one period of periodic CSI reporting. The UE may then transmit a first instance of the CSI reporting via a first uplink shared channel transmission (e.g., via a first physical uplink shared channel (PUSCH) transmission) and a second instance of the CSI reporting via a second uplink shared channel transmission (e.g., via a second PUSCH transmission) during a single period of periodic CSI reporting. Transmitting multiple instances of the CSI reporting may increase the reliability of the CSI reporting compared to a single instance of CSI reporting transmission. In addition, the UE may transmit first and second instances of the CSI report using different SRS resource sets (for example, each associated with a different transmit beam). Transmitting multiple instances of the CSI report using both the first and second SRS resource sets may further improve the reliability of the CSI report compared to a CSI report utilizing a single SRS resource set.

[0039] The aspects of this disclosure are first described in the context of wireless communication systems. Next, the aspects of this disclosure are described in the context of PUSCH transmission configurations and process flows. The aspects of this disclosure are further illustrated and described by reference to apparatus diagrams, system diagrams, and flowcharts relating to semi-persistent reporting for channel status information.

[0040] Figure 1 shows an example of a wireless communication system 100 supporting semi-persistent reporting of CSI according to an aspect of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support extended broadband communication, ultra-high reliability (e.g., mission-critical) communication, low-latency communication, communication with low-cost, low-complexity devices, or any combination thereof.

[0041] Base stations 105 may be distributed across a geographical area to form a wireless communication system 100 and may be devices of different forms or with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographical area over which base stations 105 and UEs 115 may support the communication of signals according to one or more radio access technologies.

[0042] The UE115 may be distributed across the entire coverage area 110 of the wireless communication system 100, and each UE115 may be fixed, mobile, or both at different times. The UE115 may be devices of different forms or with different capabilities. Several exemplary UE115 are shown in Figure 1. The UE115 described herein may be capable of communicating with various types of devices, such as other UE115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in Figure 1.

[0043] Base stations 105 can communicate with the core network 130, with each other, or both. For example, base stations 105 can interface with the core network 130 through one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 can communicate with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces) either directly (e.g., directly between base stations 105), indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be one or more wireless links, or may include one or more wireless links.

[0044] One or more of the base stations 105 described herein may include, or be referred to as, a base transceiver station, a radio base station, an access point, a radio transceiver, a node B, an e-node B (eNB), a next-generation node B or giganode B (either of which may be called a gNB), a home node B, a home e-node B, or other preferred terms.

[0045] UE115 may include, or may be referred to as, a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other preferred term; “device” may also be referred to as a unit, station, terminal, or client, in the examples. UE115 may also include, or may be referred to as, a personal electronic device such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE115 may include, or may be referred to as, a wireless local loop (WLL) station, an Internet of Things (IoT) device, any Internet of Things (IoE) device, or a machine-type communications (MTC) device, in the examples, or may be implemented in various items such as appliances, vehicles, meters, etc.

[0046] The UE115 described herein may be capable of communicating with other UE115s that may function as relays, as well as with various types of devices, including, among other examples, base stations 105 and network equipment, such as macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0047] UE115 and base station 105 may wirelessly communicate with each other via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication links 125. For example, a carrier used for communication link 125 may include a portion of the radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry capture signaling (e.g., synchronization signals, system information), control signaling to coordinate operations with the carrier, user data, or other signaling. The wireless communication system 100 may support communication with UE115 using carrier aggregation or multi-carrier operation. UE115 may consist of multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency-division duplex (FDD) component carriers and time-division duplex (TDD) component carriers.

[0048] The signal waveform transmitted on a carrier can consist of multiple subcarriers (for example, using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM). In systems employing MCM techniques, a resource element may consist of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier interval are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE115 receives, and the higher the order of the modulation scheme, the higher the data rate of the UE115 can be. Wireless communication resources may refer to a combination of radio frequency spectral resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communication with the UE115.

[0049] The time interval for base station 105 or UE115 is, for example, Ts = 1 / (Δf max ·N f It can refer to a sampling period of ) seconds, and can be expressed as a multiple of the basic time unit, where Δf max This can represent the maximum supported subcarrier interval, N f This may represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0050] Each frame may contain multiple sequentially numbered subframes or slots, each subframe or slot having the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into several slots. Alternatively, each frame may contain a variable number of slots, the number of slots may depend on the subcarrier interval. Each slot may contain several symbol periods (e.g., depending on the length of the cyclic prefix prepared for each symbol period). In some wireless communication systems 100, a slot may be further divided into several minislots containing one or more symbols. Except for the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f It may include a sampling period of (1) units. The duration of the symbol period may depend on the subcarrier interval or the frequency band of operation.

[0051] A subframe, slot, minislot, or symbol may be the minimum scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be called a transmit time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in the TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0052] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of the following techniques: time-division multiplexing (TDM), frequency-division multiplexing (FDM), or hybrid TDM-FDM. A control region for a physical control channel (e.g., a control resource set (core set)) may be defined by the number of symbol periods and may extend across the carrier's system bandwidth or a subset of the system bandwidth. One or more control regions (e.g., core sets) may be configured for a set of UE115s. For example, one or more UE115s may monitor or search for control regions for control information according to one or more search space sets, each search space set may include one or more control channel candidates at one or more aggregation levels located in a cascaded manner. An aggregation level for a control channel candidate may refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UE115s, and a UE-specific search space set for sending control information to a specific UE115.

[0053] In some examples, base station 105 may be mobile and therefore capable of providing communication coverage to a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but these different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, heterogeneous networks in which different types of base stations 105 provide coverage to various geographic coverage areas 110 using the same or different radio access technologies.

[0054] The wireless communication system 100 may support synchronous or asynchronous operation. In synchronous operation, base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately synchronized in time. In asynchronous operation, base stations 105 may have different frame timings, and transmissions from different base stations 105 may, in some cases, not be synchronized in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0055] The wireless communication system 100 may be configured to support ultra-high reliability communication, low latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-high reliability low latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-high reliability, low latency, or critical functions (e.g., mission-critical functions). Ultra-high reliability communication may include private or group communication and may be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and mission-critical services may be used for public safety or general commercial purposes. The terms ultra-high reliability, low latency, mission-critical, and ultra-high reliability low latency may be used interchangeably herein.

[0056] In some examples, UE115 may also be able to communicate directly with other UE115 via a device-to-device (D2D) communication link 135 (for example, using a peer-to-peer (P2P) protocol or a D2D protocol). One or more UE115s utilizing D2D communication may be within the geographical coverage area 110 of base station 105. Other UE115s in such a group may be outside the geographical coverage area 110 of base station 105, or in some cases may not be able to receive transmissions from base station 105. In some examples, a group of UE115s communicating via D2D communication may utilize a one-to-many (1:M) system where each UE115 communicates with any other UE115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication occurs between UE115s without the involvement of base station 105.

[0057] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an advanced packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)), and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access layer (NAS) functions, such as mobility, authentication, and bearer management for UE 115 serviced by base station 105 associated with the core network 130. User IP packets may be forwarded through user plane entities that may provide IP address allocation and other functions. A user plane entity may be connected to one or more network operators' IP services 150. These IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0058] Some of the network devices, such as the base station 105, may include sub-components such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmit entities 145, which may be called radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transmit entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., base station 105).

[0059] The wireless communication system 100 may typically operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is called the ultra-high frequency (UHF) region or decimeter band, as the wavelengths range from approximately 1 decimeter to 1 meter. While UHF waves may be blocked or redirected by building and environmental characteristics, their waves can penetrate structures well enough for a macrocell to service an indoor UE 115. Transmitting UHF waves may involve smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmitting using lower frequencies and longer waves in the shortwave (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0060] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial Scientific and Medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 may employ carrier sensing for collision detection and collision avoidance. In some examples, operation in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrums may include, among other examples, downlink transmission, uplink transmission, P2P transmission, or D2D transmission.

[0061] Base station 105 or UE115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE115 may be located in one or more antenna arrays or antenna panels that can support MIMO operation or transmit beamforming or receive beamforming. For example, one or more base station antennas or antenna arrays may be collated in an antenna assembly such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in diverse geographical locations. Base station 105 may have an antenna array having several rows and columns of antenna ports that base station 105 can use to support beamforming of communication with UE115. Similarly, UE115 may have one or more antenna arrays that can support various MIMO or beamforming operations. As an addition or alternative, an antenna panel may support radio frequency beamforming for signals transmitted through antenna ports.

[0062] A base station 105 or UE115 may use MIMO communication to enhance spectral efficiency by leveraging multipath signal propagation by transmitting or receiving multiple signals through different spatial layers. Such techniques are sometimes called spatial multiplexing. Multiple signals may be transmitted by a transmitting device through different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device through different antennas or different combinations of antennas. Each of the multiple signals may be called a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0063] Beamforming, sometimes called spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used in a transmitting or receiving device (e.g., base station 105, UE115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicated through the antenna elements of an antenna array such that several signals propagating in a particular direction relative to the antenna array undergo constructive interference, while other signals undergo destructive interference. The coordination of signals communicated through antenna elements may include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried through the antenna elements associated with the device. The coordination associated with each antenna element may be defined by a beamforming weight set associated with a particular direction (e.g., relative to the antenna array of the transmitting or receiving device, or to some other direction).

[0064] The base station 105 or UE 115 may use beam sweeping techniques as part of its beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Several signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by the base station 105 multiple times in different directions. For example, the base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify beam directions for later transmission or reception by the base station 105 (e.g., by a transmitting device such as the base station 105, or by a receiving device such as the UE 115).

[0065] Some signals, such as data signals associated with a specific receiving device, may be transmitted by the base station 105 in a single beam direction (for example, a direction associated with a receiving device such as UE115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE115 may receive one or more signals transmitted by the base station 105 in different directions, and UE115 may report to the base station 105 an indication of the signal received with the highest signal quality or, in some cases, an acceptable signal quality.

[0066] In some examples, transmission by a device (e.g., by base station 105 or UE115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE115). UE115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that may or may not be precoded (e.g., cell-specific reference signals (CRS), CSI reference signals (CSI-RS)). UE115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). These techniques will be described with reference to signals transmitted by the base station 105 in one or more directions, but the UE 115 may employ similar techniques to transmit signals multiple times in different directions (for example, to identify beam directions for subsequent transmission or reception by the UE 115) or to transmit signals in a single direction (for example, to transmit data to a receiving device).

[0067] When a receiving device (e.g., UE115) receives various signals from a base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals, it may attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device may attempt multiple receiving directions by receiving through different antenna subarrays, by processing the received signal according to different antenna subarrays, by receiving according to different sets of receive beamforming weights (e.g., different directional listening weights) applied to the received signal at multiple antenna elements of an antenna array, or by processing the received signal according to different sets of receive beamforming weights applied to the received signal at multiple antenna elements of an antenna array, any of which may be referred to as “listening” by different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receiving configuration may be matched to a beam direction determined based on listening by different receiving configuration directions (e.g., the beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or possibly acceptable signal quality, based on listening by multiple beam directions).

[0068] In some wireless communication systems 100, UE 115 may communicate with base station 105 using multiple iterations of uplink communication (possibly by different transmit beams) to increase the likelihood of successful reception of uplink communication. For example, base station 105 may transmit signaling that activates periodic CSI reporting, and UE 115 may identify trigger conditions that trigger both a first instance of CSI reporting and a second instance of CSI reporting within one period of periodic CSI reporting. UE 115 may then transmit a first instance of CSI reporting via a first uplink shared channel transmit (e.g., via a first physical uplink shared channel (PUSCH) transmit) and a second instance of CSI reporting via a second uplink shared channel transmit (e.g., via a second PUSCH transmit) during a single period of periodic CSI reporting. Transmitting multiple instances of CSI reporting may increase the reliability of CSI reporting compared to a single instance of CSI reporting transmission. In addition, the UE115 may transmit first and second instances of the CSI report using different SRS resource sets (for example, each associated with a different transmit beam). Transmitting multiple instances of the CSI report using both the first and second SRS resource sets may further improve the reliability of the CSI report compared to a CSI report utilizing a single SRS resource set.

[0069] Figure 2 shows an example of a wireless communication system 200 supporting semi-permanent reporting of CSI according to an aspect of this disclosure. In some examples, the wireless communication system 200 may implement an aspect of the wireless communication system 100. For example, the wireless communication system 200 includes a base station 105a and a UE 115a, which may be examples of the respective devices described with reference to Figure 1. References to specific wireless devices in the figure below (e.g., UE 115, TRP, base station 105) are provided for illustrative purposes only, and it should be understood that various wireless devices not specifically mentioned herein may be used interchangeably with the devices described herein. Similarly, in some cases, the operations described performed by UE 115-a may be performed by base station 105-a (or a TRP associated with base station 105-a), and vice versa.

[0070] In some cases, the communication shown in the wireless communication system 200 may be an example of UE 115-a performing semi-persistent reporting of CSI in response to downlink control information (DCI) 215 which activates periodic CSI reporting via uplink shared channel transmission (e.g., via PUSCH transmission 230). Before transmitting DCI 215, base station 105-a may transmit radio resource control (RRC) signaling 210 indicating a set of trigger states (e.g., up to 64) associated with each CSI reporting configuration corresponding to a unique CSI reporting setting. For example, base station 105-a may transmit RRC signaling 210 including the SemiPersistentOnPUSCH-TriggerStateList parameter. For example, each trigger state may indicate a period 225 for periodic CSI reporting (e.g., based on the number of slots indicated by the reportSlotConfig parameter). In addition, each trigger state may indicate the transmit power for transmitting a PUSCH transmission 230 carrying a periodic CSI report 220 (for example, by indicating P0, or offset, and alpha, or a factor for partial power loss compensation).

[0071] In some cases, the RRC signaling 210 may additionally constitute the type of PUSCH repetition for the PUSCH transmission 230. For example, base station 105-a may indicate (e.g., via the RRC signaling 210) the type of PUSCH repetition in which each repetition of the PUSCH transmission is transmitted through the same set of slots in a symbol. For example, base station 105-a may indicate to UE 115-a that each repetition of the PUSCH transmission is transmitted through a certain number of (e.g., the same number as the number of PUSCH repetitions) of 4 to 10 slots in a symbol. In another example, base station 105-a may indicate a type of PUSCH repetition in which each PUSCH repetition is consecutive. For example, each PUSCH repetition may be transmitted by a consecutive set of symbols that cross slot boundaries. In this type of PUSCH repetition, base station 105-a may indicate a nominal number of PUSCH repetition transmissions, which may differ from the actual number of PUSCH repetition transmissions. In some cases, the nominal PUSCH repetition transmission may include symbols that cross slot boundaries. Here, UE115-a may transmit two actual PUSCH iterations corresponding to a single nominal PUSCH iteration (for example, each associated with a symbol associated with a single slot). In another case, UE115-a may determine that one or more of the symbols associated with the nominal PUSCH iteration may be invalid (for example, due to a quasi-static downlink symbol, based on the invalidity of the symbol's representation, or due to a synchronization signal block (SSB) symbol, for a symbol associated with control resource set (CORESET) 0 for a physical downlink control channel (PDCCH) of type 0). Here, the actual PUSCH iteration may contain fewer symbols than the nominal PUSCH iteration.

[0072] After transmitting the RRC signaling 210, base station 105-a may transmit a DCI 215 to activate periodic CSI reporting via a PUSCH transmission. In some cases, the DCI 215 may indicate one of the trigger conditions configured by the RRC signaling 210. In some examples, the DCI 215 may be encrypted using a semi-persistent-channel-state-information-radio-network-temporary identifier (SP-CSI-RNTI).

[0073] Based on receiving DCI215, UE115-a may identify a single CSI report configuration associated with the indicated trigger state. Additionally, UE115-a may identify whether a trigger condition is satisfied that triggers the transmission of both a first instance and a second instance of the CSI report 220 within a period 225 of the periodic CSI report. If UE115-a determines that the trigger condition is satisfied, UE115-a may transmit a first instance of the CSI report 220 via a first PUSCH transmission 230 and a second instance of the CSI report 220 via a second PUSCH transmission 230 within each period 225 of the periodic CSI report by the transmit beam 205. For example, UE115-a may transmit a first instance of the CSI report 220 via PUSCH transmit 230-a and a second instance of the CSI report 220 via PUSCH transmit 230-b within period 225-a. Alternatively, if UE115-a determines that the trigger condition is not satisfied, UE115-a may transmit a single instance of the CSI report 220 via transmit beam 205 within each period 225 of the periodic CSI report. That is, UE115-a may transmit the CSI report 220 via PUSCH transmits 230-a, 230-c, and 230-e, and refrain from transmitting the CSI report via PUSCH transmits 230-b, 230-d, and 230-f.

[0074] In some cases, when UE115-a determines that the trigger condition is met, DCI215 may indicate two trigger states, each associated with a CSI reporting configuration. In some examples, the two CSI reporting configurations may each indicate different transmit powers (e.g., via different offset values, partial power loss compensation values, or both) for transmitting instances of the CSI report 220. In a first example, UE115-a may transmit a first instance of the CSI report 220 via the PUSCH transmit 230 using transmit beam 205-a associated with a first sound reference signal (SRS) source set. In addition, UE115-a may transmit a second instance of the CSI report 220 via the PUSCH transmit 230 using transmit beam 205-b associated with a second SRS source set. Here, UE115-a may transmit a first instance of the CSI report 220 using a first transmit power (indicated, for example, by a first trigger state), and a second instance of the CSI report 220 using a second transmit power (indicated, for example, by a second trigger state). In the second example, UE115-a may transmit both instances of the CSI report 220 via the PUSCH transmit 230 using the same transmit beam 205 associated with a single SRS source set, where UE115-a may transmit both instances of the CSI report 220 using a single transmit power (indicated, for example, by one of the trigger states).

[0075] In one example, UE115-a may determine that the trigger condition is satisfied based on DCI215 indicating a first SRS associated with a first PUSCH transmit 230 and a second SRS associated with a second PUSCH transmit 230. For example, DCI215 may indicate that PUSCH transmits 230-a, 230-c, and 230-e are associated with one set of SRS resources, and PUSCH transmits 230-b, 230-d, and 230-f are associated with another set of SRS resources. UE115-a may then determine that the trigger condition is satisfied and that two instances of the CSI report 220 can be transmitted within each period 225 using different PUSCH transmits 230 associated with different sets of SRS resources. Here, UE115-a may transmit the PUSCH transmits 230 within each period 225 using different transmit beams 205. For example, UE115-a may transmit a PUSCH transmission 230 related to a first SRS resource set using transmit beam 205-a. In addition, UE115-a may transmit a PUSCH transmission 230 related to a second SRS resource set using transmit beam 205-b.

[0076] In another example, UE115-a may determine that the trigger condition is satisfied based on DCI215 indicating two or more repetitions of the PUSCH transmission 230. In some cases, DCI215 may indicate three or more repetitions of the PUSCH transmission 230 (for example, within each period 225). Here, UE115-a may still transmit two PUSCH transmissions 230 within each period. Additionally or alternatively, UE115-a may determine that the trigger condition is satisfied based on DCI215 indicating a trigger state related to a CSI reporting configuration that shows both the first and second instances of the CSI report. That is, RRC signaling 210 may additionally indicate, for each trigger state, whether the trigger state is associated with a single CSI reporting instance within each period 225, or with two CSI reporting instances within each period 225. In another example, UE115-a may determine that the trigger condition is satisfied based on the fact that DCI215 contains a field (e.g., a single bit in DCI215) indicating whether the activated trigger state is associated with a single CSI reporting instance within each period 225, or with two CSI reporting instances within each period 225.

[0077] Figures 3A and 3B show examples of PUSCH transmission configurations 300 supporting semi-persistent reporting of CSI according to aspects of the present disclosure. For example, a PUSCH transmission configuration 300 may include an exemplary configuration including two PUSCH transmissions 305 transmitted within each period 325 of periodic CSI reporting. In addition, each PUSCH transmission 305 may include an instance of CSI reporting 310. In some examples, a PUSCH transmission configuration 300 may implement a form of wireless communication as described with reference to Figures 1 and 2. For example, for both PUSCH transmission configurations 300, a base station may configure semi-persistent reporting of CSI including two instances of CSI reporting 310 within each period 325 of periodic CSI reporting (e.g., by RRC signaling, by DCI), as described with reference to Figures 1 and 2.

[0078] In the example of PUSCH transmission configuration 300-a, the actual PUSCH transmissions 305-a, 305-b, and 305-d may be the same as the nominal PUSCH transmissions 305-a, 305-b, and 305-d. In addition, the actual PUSCH transmission 305-c may differ from the nominal PUSCH transmission 305-c. For example, the UE may determine that one or more symbols associated with PUSCH transmission 305-c are invalid. In this case, the UE may refrain from transmitting PUSCH transmission 305-c within period 325-b. The UE may still transmit PUSCH transmission 305-d within period 325-b (even if, for example, the actual transmission of other PUSCH transmissions 305-c within period 325-b differs from the nominal transmission of PUSCH transmission 305-c).

[0079] In the example of PUSCH transmission configuration 300-b, the actual PUSCH transmissions 305-e, 305-f, and 305-h may be the same as the nominal PUSCH transmissions 305-e, 305-f, and 305-h. In addition, the actual PUSCH transmission 305-g may differ from the nominal PUSCH transmission 305-g. For example, the UE may determine that one or more symbols associated with PUSCH transmission 305-g are invalid. In this case, the UE may refrain from transmitting PUSCH transmission 305-g within period 325-d. The UE may also refrain from transmitting PUSCH transmission 305-h within period 325-d, even if the actual transmission of PUSCH transmission 305-h and the nominal transmission of PUSCH transmission 305-h are the same. In other words, if either of the actual PUSCH transmissions 305 differs from the nominal PUSCH transmission 305, the UE will not transmit a PUSCH transmission 305 within period 325.

[0080] Figure 4 shows an example of a process flow 400 supporting semi-permanent reporting of CSI according to the embodiments of this disclosure. In some embodiments, the process flow 400 may implement embodiments of Figures 1 to 3. For example, UE115-b may be an example of UE115 as described in relation to Figures 1 to 3. In addition, base station 105-b may be an example of base station 105 as described in relation to Figures 1 to 3.

[0081] In 405, base station 105-b may transmit RRC signaling to UE115-b. For example, UE115-b may receive RRC signaling indicating a set of trigger states associated with each CSI reporting configuration.

[0082] In 410, base station 105-b may transmit a DCI to UE115-b. For example, UE115-b may receive a DCI that activates a periodic CSI report via uplink shared channel transmission. In some cases, the DCI may activate the periodic CSI report by indicating one trigger state from a set of trigger states.

[0083] In 415, UE115-b may identify trigger conditions that trigger the transmission of both a first instance of a CSI report and a second instance of a CSI report within one period of a periodic CSI report.

[0084] In 420, UE115-b may determine that a trigger condition is satisfied. In one example, UE115-b may determine that a trigger condition is satisfied based on the DCI indicating both a first SRS resource set associated with a first uplink shared channel transmission and a second SRS resource set associated with a second uplink shared channel transmission. In another example, UE115-b may determine that a trigger condition is satisfied based on the DCI indicating two or more iterations of uplink shared channel transmissions within one period of periodic CSI reporting. In yet another example, UE115-b may determine that a trigger condition is satisfied based on a trigger state (e.g., indicated by DCI) being associated with a CSI reporting configuration indicating transmissions of both a first instance of a CSI report and a second instance of a CSI report within one period of periodic CSI reporting. In another example, UE115-b may determine that a trigger condition is satisfied based on the value of a field in DCI configured to indicate either the transmission of both a first instance and a second instance of a CSI report within one period of a periodic CSI report, or the transmission of a single CSI report within one period of a periodic CSI report.

[0085] In 425, UE115-b may, based on the satisfaction of the trigger condition, transmit a first instance of the CSI report via a first uplink shared channel transmit and a second instance of the CSI report via a second uplink shared channel transmit, both of which fall within one period of the periodic CSI report. If DCI indicates two sets of SRS resources associated with the first and second uplink shared channel transmits, UE115-b may transmit a first instance of the CSI report via the first uplink shared channel transmit using a first transmit beam associated with the first SRS resource set. In addition, UE115-b may transmit a second instance of the CSI report via the second uplink shared channel transmit using a second transmit beam associated with the second SRS resource set.

[0086] Figure 5 shows a block diagram 500 of a device 505 supporting semi-persistent reporting of a CSI according to an aspect of this disclosure. Device 505 may be an example of an aspect of UE 115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communications manager 520. Device 505 may also include a processor. Each of these components may communicate with one another (for example, via one or more buses).

[0087] The receiver 510 may provide means for receiving information such as packets, user data, control information, or any combination thereof related to various information channels (e.g., control channel, data channel, information channel related to semi-persistent reporting of CSI). The information may be passed to other components of device 505. The receiver 510 may utilize a single antenna or a set of multiple antennas.

[0088] The transmitter 515 may provide means for transmitting signals generated by other components of device 505. For example, the transmitter 515 may transmit information such as packets, user data, control information, or any combination thereof related to various information channels (e.g., control channel, data channel, information channel related to semi-persistent reporting of CSI). In some examples, the transmitter 515 may be placed in a transceiver module alongside the receiver 510. The transmitter 515 may utilize a single antenna or a set of multiple antennas.

[0089] The communications manager 520, the receiver 510, the transmitter 515, or various combinations thereof or of various components thereof may be examples of means for performing various aspects of the semi-persistent reporting of the CSI described herein. For example, the communications manager 520, the receiver 510, the transmitter 515, or various combinations thereof or components may support a method for performing one or more of the functions described herein.

[0090] In some examples, the communications manager 520, the receiver 510, the transmitter 515, and various combinations or components thereof may be implemented in hardware (for example, in communications management circuits). The hardware may include a processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as means for performing the functions described herein, or optionally supporting such means. In some examples, the processor and memory coupled to the processor may be configured to perform one or more of the functions described herein (for example, by the processor executing instructions stored in memory).

[0091] As an addition or alternative, in some examples, the communications manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be implemented within code executed by a processor (for example, as communications management software or firmware). When implemented within code executed by a processor, the functions of the communications manager 520, receiver 510, transmitter 515, or various combinations or components thereof may be performed by any combination of a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any other programmable logic device (for example, configured as a means for performing the functions described herein, or optionally supporting such means).

[0092] In some examples, the communications manager 520 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or in cooperation with the receiver 510, the transmitter 515, or both. For example, the communications manager 520 may be integrated with the receiver 510, the transmitter 515, or both to receive information from the receiver 510 and send information to the transmitter 515, or to receive information and transmit information, or to perform various other operations as described herein.

[0093] The communications manager 520 may support wireless communications in the UE in accordance with the examples described herein. For example, the communications manager 520 may be configured, or may optionally support, means for receiving a DCI from a base station that activates periodic CSI reporting via uplink shared channel transmissions. The communications manager 520 may be configured, or may optionally support, means for identifying trigger conditions that trigger the transmission of both a first instance of CSI reporting and a second instance of CSI reporting within one cycle of periodic CSI reporting.

[0096] Receiver 610 may provide means for receiving information such as packets, user data, control information, or any combination thereof related to various information channels (e.g., control channel, data channel, information channel related to semi-persistent reporting of CSI). The information may be passed to other components of device 605. Receiver 610 may utilize a single antenna or a set of multiple antennas.

[0097] Transmitter 615 may provide means for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit information such as packets, user data, control information, or any combination thereof related to various information channels (e.g., control channel, data channel, information channel related to semi-persistent reporting of CSI). In some examples, transmitter 615 may be placed in tandem with receiver 610 within the transceiver module. Transmitter 615 may utilize a single antenna or a set of multiple antennas.

The trigger condition manager 630 may be configured, or may optionally support, means for identifying trigger conditions that trigger the transmission of both a first instance of CSI reporting and a second instance of CSI reporting within one period of periodic CSI reporting. The CSI reporting transmitter 635 may be configured, or may optionally support, means for transmitting a first instance of CSI reporting via a first uplink shared channel transmission and a second instance of CSI reporting via a second uplink shared channel transmission, based on the satisfaction of the trigger conditions, both of which fall within one period of periodic CSI reporting.

[0100] Figure 7 shows a block diagram 700 of a communications manager 720 supporting semi-persistent reporting of a CSI according to an aspect of this disclosure. The communications manager 720 may be an example of an aspect of the communications manager 520, communications manager 620, or both, as described herein. The communications manager 720 or various components thereof may be an example of means for performing various aspects of semi-persistent reporting of a CSI as described herein. For example, the communications manager 720 may include a DCI receiver 725, a trigger condition manager 730, a CSI report transmitter 735, an RRC signaling receiver 740, or any combination thereof. Each of these components may communicate with each other directly or indirectly (for example, via one or more buses).

[0101] The communications manager 720 may support wireless communications in the UE in accordance with the examples described herein. The DCI receiver 725 may be configured, or may optionally support, means for receiving a DCI from a base station that activates periodic CSI reporting via uplink shared channel transmissions. The trigger condition manager 730 may be configured, or may optionally support, means for identifying trigger conditions that trigger the transmission of both a first instance of CSI reporting and a second instance of CSI reporting within one period of periodic CSI reporting. The CSI reporting transmitter 735 may be configured, or may optionally support, means for transmitting a first instance of CSI reporting via a first uplink shared channel transmission and a second instance of CSI reporting via a second uplink shared channel transmission, based on the satisfaction of the trigger conditions, both of which fall within one period of periodic CSI reporting.

[0102] In some examples, the trigger condition manager 730 may be configured, or may support, a means for determining that a trigger condition is satisfied based on the DCI indicating both a first SRS resource set associated with a first uplink shared channel transmission and a second SRS resource set associated with a second uplink shared channel transmission.

[0103] In some examples, to support transmission, the CSI report transmitter 735 may be configured, or may optionally support, a means for transmitting a first instance of a CSI report via a first uplink shared channel transmission using a first transmit beam associated with a first SRS resource set. In some examples, to support transmission, the CSI report transmitter 735 may be configured, or may optionally support, a means for transmitting a second instance of a CSI report via a second uplink shared channel transmission using a second transmit beam associated with a second SRS resource set.

[0104] In some examples, the trigger condition manager 730 may be configured, or may support, a means for determining that a trigger condition is satisfied based on the DCI indicating two or more iterations of uplink shared channel transmissions within one period of periodic CSI reporting.

[0105] In some examples, the RRC signaling receiver 740 may be configured, or may support, a means for receiving RRC signaling from a base station indicating a set of multiple trigger states, each associated with a CSI reporting configuration, and the DCI activates the periodic CSI reporting by indicating one trigger state from the set of multiple trigger states.

[0106] In some examples, the trigger condition manager 730 may be configured, or may support, a means for determining that a trigger condition is satisfied, based on the fact that a single trigger condition relates to a CSI reporting configuration that indicates the transmission of both a first instance and a second instance of a CSI report within one period of a periodic CSI report.

[0107] In some examples, the trigger condition manager 730 may be configured, or may support, a means for determining that a trigger condition is satisfied based on the value of a field in the DCI configured to indicate either the transmission of both a first instance and a second instance of a CSI report within one period of a periodic CSI report, or the transmission of a single CSI report within one period of a periodic CSI report.

[0108] In some examples, the CSI report transmitter 735 may be configured, or may support, a means for determining, based on the satisfaction of trigger conditions, to transmit two iterations of a PUSCH transmission within each period of periodic CSI reporting, the two iterations comprising a first uplink shared channel transmission and a second uplink shared channel transmission.

[0109] In some cases, the number of repetitions of PUSCH transmissions within each period of periodic CSI reporting is one or three or more.

[0110] In some examples, the CSI report transmitter 735 may be configured, or may support, a means for determining, to transmit a second CSI report during a second period of periodic CSI reporting via a third PUSCH transmission and a fourth PUSCH transmission after one period of periodic CSI reporting. In some examples, the CSI report transmitter 735 may be configured, or may support, a means for identifying, that the actual transmission of one PUSCH transmission from the third or fourth PUSCH transmission differs from the nominal transmission of one PUSCH transmission. In some examples, the CSI report transmitter 735 may be configured, or may support, a means for refraining from transmitting one PUSCH transmission during a second period of periodic CSI reporting based on the identification that the actual transmission differs from the nominal transmission.

[0111] In some examples, the CSI report transmitter 735 may be configured, or may support, a means for transmitting other PUSCH transmissions, including a second CSI report, from a third PUSCH transmission and a fourth PUSCH transmission, based on the fact that the actual transmission of the other PUSCH transmission is the same as the nominal transmission of the other PUSCH transmission, within a second period of periodic CSI reporting.

[0112] In some examples, the CSI report transmitter 735 may be configured, or may support in some cases, as a means to refrain from transmitting one other PUSCH transmission from a third PUSCH transmission and a fourth PUSCH transmission, based on the fact that the actual transmission of another PUSCH transmission differs from the nominal transmission of another PUSCH transmission.

[0113] In some examples, DCI activates periodic CSI reporting based on trigger conditions associated with a CSI reporting configuration indicating a first transmit power and a second transmit power, and the transmission of the first instance and the second instance of the CSI reporting is based on at least one of the first or second transmit power.

[0114] In some examples, to support transmission, the CSI report transmitter 735 may be configured, or may optionally support, a means for transmitting a first instance of the CSI report via a first uplink shared channel transmission using a first set of SRS resources indicated by the DCI, according to a first transmission power. In some examples, to support transmission, the CSI report transmitter 735 may be configured, or may optionally support, a means for transmitting a second instance of the CSI report via a second uplink shared channel transmission using a second set of SRS resources indicated by the DCI, according to a second transmission power.

[0115] In some examples, to support transmission, the CSI report transmitter 735 may be configured, or may support, a means for transmitting both a first instance of the CSI report and a second instance of the CSI report according to a first transmit power, based on the DCI indicating a single set of SRS resources, both of which use a single set of SRS resources.
