Semi-persistent reporting of channel state information

Abstract

Methods, systems, and devices for wireless communication are described. In some wireless communication systems, a user equipment (UE) can receive, from a base station, downlink control information (DCI) that activates a periodic channel state information (CSI) report for transmission via an uplink shared channel (e.g., via a physical uplink shared channel (PUSCH) transmission). The UE can then identify a trigger condition that triggers transmission of both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report. Based on satisfaction of the trigger condition, the UE can transmit the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, where both uplink channel transmissions are within the period of the periodic CSI report.

Technical Field

[0003] The following pertains to wireless communication, including semi-persistent reporting of channel state information. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can 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 Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ various 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 Extended 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 of which simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE).

[0005] Some wireless communication systems can support communication using one or more antenna arrays at different devices. For example, a network can use one or more transmit / receive points (TRPs) to communicate with a UE, where each TRP and UE can have one or more antenna arrays to form a directional beam. Efficient communication between each UE and one or more TRPs can help improve network throughput, latency, and reliability, and therefore further improvements to techniques for efficient communication are desirable.

[0006] Overview

[0007] The described techniques relate to improved methods, systems, devices, and apparatuses that support semi-persistent reporting of channel state information. Various aspects provide techniques for communication between a user equipment (UE) and a base station, where the UE can transmit multiple repetitions of an uplink communication over different transmit beams to improve the likelihood of successful reception of the uplink communication. For example, the base station can transmit signaling that activates a periodic channel state information (CSI) report, and the UE can identify a trigger condition that triggers both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report. The UE can then transmit the first instance of the CSI report via a first uplink shared channel transmission (e.g., via a first physical uplink shared channel (PUSCH) transmission) and the second instance of the CSI report via a second uplink shared channel transmission (e.g., via a second PUSCH transmission) during a single period of the periodic CSI report. By transmitting multiple instances of the CSI report, the reliability of the CSI report can be higher than a single instance of the CSI report transmission. Additionally, the UE can transmit the first and second instances of the CSI report using different sounding reference signal (SRS) resource sets (e.g., each SRS resource set is associated with a different transmit beam). Here, transmitting multiple instances of the CSI report over both the first SRS resource set and the second SRS resource set can further improve the reliability of the CSI report when compared to a CSI report that utilizes a single SRS resource set.

[0008] A method for wireless communication at a UE is described. The method can include receiving, from a base station, downlink control information (DCI) that activates a periodic CSI report transmitted via uplink shared channel transmissions, identifying a trigger condition that triggers transmission of both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report, and transmitting, based on satisfaction of the trigger condition, the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, both the first uplink shared channel transmission and the second uplink shared channel transmission being within the period of the periodic CSI report.

[0051] DETAILED DESCRIPTION

[0052] In some wireless communications systems, a user equipment (UE) can communicate with a base station using multiple repetitions of an uplink communication (in some cases over different transmit beams) to improve the likelihood of successful reception of the uplink communication. For example, a base station can transmit signaling that activates a periodic channel state information (CSI) report, and a UE can identify a trigger condition that triggers both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report. The UE can then transmit the first instance of the CSI report via a first uplink shared channel transmission (e.g., via a first physical uplink shared channel (PUSCH) transmission) and the second instance of the CSI report via a second uplink shared channel transmission (e.g., via a second PUSCH transmission) during a single period of the periodic CSI report. By transmitting multiple instances of the CSI report, the reliability of the CSI report can be higher than a single instance of the CSI report transmission. Additionally, the UE can transmit the first and second instances of the CSI report using different SRS resource sets (e.g., each SRS resource set is associated with a different transmit beam). Here, transmitting multiple instances of the CSI report over both the first SRS resource set and the second SRS resource set can further improve the reliability of the CSI report when compared to a CSI report utilizing a single SRS resource set.

[0053] Aspects of the disclosure are initially described in the context of a wireless communications system. Aspects of the disclosure are then described in the context of PUSCH transmission configurations and process flows. Aspects of the disclosure are further illustrated by and described in conjunction with apparatus diagrams, system diagrams, and flowcharts related to semi-persistent reporting of channel state information.

[0054] Figure 1An example of a wireless communications system 100 that supports semi-persistent reporting of CSI in accordance with aspects of the present disclosure is illustrated. The wireless communications system 100 can include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 can 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 communications system 100 can support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0055] The base stations 105 can be dispersed throughout the geographic area 100 and can be

[0056] The UEs 115 can be dispersed throughout the geographic area 100, and each UE 115 can be stationary or mobile or both at different times. The UEs 115 can be devices in different forms Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115, 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 FIG. 1. Figure 1

[0057] The base stations 105 can communicate with the core network 130, or with one another, or both. For example, the base stations 105 can interface with the core network 130 through one or more backhaul links 120 (e.g., via an SI, N2, N3, or other interface). The base stations 105 can communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) directly (e.g., directly between base stations 105), or indirectly (e.g., via core network 130), or both. In some examples, the backhaul links 120 can be or include one or more wireless links.

[0058] ​One or more of the base stations 105 described herein can include or can be referred to as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which can be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology.

[0059] A UE 115 can include or can be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” can also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 can also include or can be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 can include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which can be implemented in various objects such as appliances, or vehicles, among other examples.

[0060] The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 that can sometimes act as relays or Figure 1 network equipment including base stations 105 and customer premises equipment.

[0061] The UEs 115 and the base stations 105 can wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The

[0062] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing 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 code rate of the modulation scheme, or both). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can achieve. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0063] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·N f ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0064] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into several time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include several symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0065] A subframe, a slot, a mini-slot, or a symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and can be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0066] Physical channels can be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel can be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by a number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search the control region for control information according to one or more search space sets, and each search space set can include one or more control channel candidates arranged in the cascaded manner in one or more aggregation levels. An aggregation level for a control channel candidate can 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. A search space set can include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets configured for sending control information to a specific UE 115.

[0067] In some examples, base stations 105 can be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communications system 100 can include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0068] The wireless communications system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timings, and transmissions from different base stations 105 can not be aligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

[0069] The wireless communications system 100 can be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 can be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. UEs 115 can be designed to support ultra-reliable, low-latency, or mission critical functions (e.g., mission critical function). Ultra-reliable communications can include private communication or group communication and can 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 can include prioritization of services, and mission critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low- latency can be used interchangeably herein.

[0070] In some examples, UEs 115 can also be able to communicate directly with other UEs 115 using a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communications can be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group can be outside the geographic coverage area 110 of a base station 105 or be otherwise unserved by a base station 105. In some examples, groups of the UEs 115 communicating via D2D communications can utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the D2D communications between UEs 115 by transmitting

[0071] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or 5G core (5GC), which can 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, such as a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF). The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets can be transferred through the user plane entity, which can provide IP address allocation as well as other functions. The user plane entity can be connected to the IP services 150 of the one or more network operators. The IP services 150 can include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.

[0072] Some of the network devices, such as a base station 105, can include subcomponents such as an access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with UEs 115 through one or more other access network transmission entities 145, which can be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105).

[0073] The wireless communications system 100 can operate using one or more frequency bands, often in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band, since the wavelengths range from approximately one decimeter to one meter in length. The UHF region includes bands such as the 700 MHz, 800 MHz, 900 MHz, 1.4 GHz, 1.9 GHz, and 2.1 GHz bands. The region from 3 GHz to 30 GHz is known as the super-high frequency (SHF) region or centimeter band, since the wavelengths range from approximately one centimeter to one meter in length. The SHF region includes bands such as the 5 GHz band. The region from 30 GHz to 300 GHz is known as the extremely high frequency (EHF) region or millimeter band, since the wavelengths range from approximately one millimeter to one centimeter in length. The EHF region includes bands such as the 38 GHz and 60 GHz bands. The wireless communications system 100 can support continuous

[0074] Wireless communications system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communications system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed frequency band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed frequency

[0075] Base stations 105 or UEs 115 can be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. Base stations 105 or UEs 115 can use their multiple antennas to improve the reliability and throughput of communications. For instance, base stations 105 or UEs 115 can use beamforming to focus energy in a communication signal towards a receiving device. For example, a base station 105 can use beamforming to project energy towards a UE 115 to which the base station 105 is communicating. Similarly, a UE 115 can use beamforming to project energy towards a base station 105 with which the UE 115 is communicating. Antennas of base stations 105 or UEs 115 can be co-located within one or more antenna arrays or antenna panels that can support MIMO operations or beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 can be located at different geographic locations. A base station 105 can have an array of antennas that have a number of rows and columns of antenna ports that the base station 105 can use for beamforming in support of communications with UEs 115. Likewise, a UE 115 can have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel can support radio frequency beamforming for signals communicated via the antenna ports.

[0076] Base stations 105 or UEs 115 can use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency of wireless communications. Such techniques can be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a spatial stream, and can carry bits associated with the same data stream (e.g., a same codeword) or different data streams (e.g., different codewords). Different spatial layers can 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 multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0077] Beamforming, which can also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer a beam of energy in a specific direction along with the spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining the signals communicated by antennas of an antenna array such that signals transmitted or received with certain orientations (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) experience constructive interference while others experience destructive interference. The combination of signals can be performed according to a beamforming weight set associated with a particular orientation. The beamforming weight set can include amplitude weights, phase weights, or both. The beamforming weight set can be defined such that signals transmitted or received with the beam oriented in a particular direction exhibit a desired signal characteristic such as a signal strength that is maximized (or maximally improved), a signal-to-noise ratio that is maximized (or maximally improved), a noise figure that is minimized (or minimized), or some other signal characteristic.

[0078] The base stations 105 or the UEs 115 can use beamforming techniques as part of an effort to reduce or minimize interference. For example, a transmitting device (e.g., a base station 105) can apply beamforming techniques to steer the energy of a transmission in a desired direction, thus possibly minimizing transmission of the energy in other directions. Similarly, a receiving device (e.g., a UE 115) can apply beamforming techniques to steer the energy of a received transmission in a desired direction, thus possibly minimizing transmission of the energy in other directions.

[0079] Some signals, such as data signals associated with a particular receiving device, can be transmitted by a base station 105 in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 115). In some examples, the beam direction associated with transmissions along a single beam direction can be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions and can report to the base station 105 an indication of the signal that the UE 115 received with a highest signal quality, or an otherwise acceptable signal quality.

[0080] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 105 to a UE 115). A UE 115 can report feedback that indicates precoding weights for one or more beam directions, and the feedback can correspond to a configured number of beams across a system bandwidth or one or more sub-bands. A base station 105 can transmit reference signals (e.g., a cell-specific reference signal (CRS), a CSI-RS) that can be precoded or unprecoded. A UE 115 can provide feedback for beam selection that can 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). Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 can employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by a UE 115) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

[0081] A receiving device (e.g., a UE 115) can try multiple receive configurations (e.g., directional listening) when receiving various signals from base stations 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device can try multiple receive directions by use of different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which can be referred to as“listening” according to different receive configurations or receive directions. In some examples, a receiving device can use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration can be aligned in a beam direction determined based on listening in different beam directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0082] In some wireless communications systems 100, a UE 115 can communicate with a base station 105 using multiple repetitions of an uplink communication (in some cases over different transmit beams) to improve the likelihood of successful reception of the uplink communication. For example, a base station 105 can transmit signaling that activates a periodic CSI report, and a UE 115 can identify a trigger condition that triggers both a first instance and a second instance of a CSI report within a period of the periodic CSI report. The UE 115 can then transmit the first instance of the CSI report via a first uplink shared channel transmission (e.g., via a first physical uplink shared channel (PUSCH) transmission) and the second instance of the CSI report via a second uplink shared channel transmission (e.g., via a second PUSCH transmission) during a single period of the periodic CSI report. By transmitting multiple instances of the CSI report, the reliability of the CSI report can be higher than a single instance of the CSI report transmission. Additionally, the UE 115 can transmit the first and second instances of the CSI report using different SRS resource sets (e.g., each SRS resource set is associated with a different transmit beam). Here, transmitting multiple instances of the CSI report over both the first SRS resource set and the second SRS resource set can further improve the reliability of the CSI report when compared to a CSI report that utilizes a single SRS resource set.

[0083] Figure 2 An example of a wireless communications system 200 that supports semi-persistent reporting of CSI in accordance with aspects of the present disclosure is illustrated. In some examples, wireless communications system 200 can implement aspects of wireless communications system 100. For example, wireless communications system 200 can include a base station 105 and a UE 115-a, which can be examples of the respective devices as described with reference to Figure 1 It should be understood that references to particular wireless devices (e.g., UEs 115, TRPs, base stations 105) in the following figures are made for illustrative purposes only and different wireless devices not specifically mentioned herein can be used interchangeably with those described herein. Likewise, in some cases, operations described as being performed by a UE 115-a can be performed by a base station 105-a (or a TRP associated with the base station 105-a), and vice versa.

[0084] In some cases, the communications illustrated in wireless communications system 200 can be an example of a UE 115-a performing semi-persistent reporting of CSI in response to downlink control information (DCI) 215 activating periodic CSI reporting via uplink shared channel transmissions (e.g., via PUSCH transmissions 230). Prior to transmitting DCI 215, base station 105-a can transmit radio resource control (RRC) signaling 210 indicating a set of trigger states (e.g., up to 64 trigger states), each trigger state associated with a CSI reporting configuration corresponding to a unique CSI reporting setting. For example, base station 105-a can transmit RRC signaling 210 including a SemiPersistentOnPUSCH-TriggerStateList parameter. For example, each trigger state can indicate a periodicity 225 of the periodic CSI reporting (e.g., based on a number of slots indicated by a reportSlotConfig parameter). In addition, each trigger state can indicate a transmit power for transmitting PUSCH transmissions 230 carrying the periodic CSI reporting 220 (e.g., by indicating a P0, or an offset and a, or a factor for fractional power loss compensation).

[0085] In some cases, RRC signaling 210 can additionally configure a PUSCH repetition type for PUSCH transmissions 230. For example, base station 105-a can indicate (e.g., via RRC signaling 210) a PUSCH repetition type in which each repetition of a PUSCH transmission is transmitted via a same set of slots within a symbol. For example, base station 105-a can indicate that UE 115-a is to transmit each repetition of a PUSCH transmission via the fourth through tenth slots within a number of symbols (e.g., the same as a number of PUSCH repetitions). In another example, base station 105-a can indicate a PUSCH repetition type in which each PUSCH repetition is contiguous. For example, each PUSCH repetition can be transmitted by a contiguous set of symbols that span a slot boundary. In such a PUSCH repetition type, base station 105-a can indicate a number of nominal PUSCH repetition transmissions, which can be different than a number of actual PUSCH repetition transmissions. In one case, a nominal PUSCH repetition transmission can include a symbol that spans a slot boundary. Here, UE 115-a can transmit two actual PUSCH repetitions corresponding to a single nominal PUSCH repetition (e.g., each actual PUSCH repetition is associated with a symbol associated with a single slot). In another case, UE 115-a can determine that one or more of the symbols associated with a nominal PUSCH repetition can be invalid (e.g., due to a semi-static downlink symbol, an indication based on symbol invalidity, due to a synchronization signal block (SSB) symbol, for symbols associated with control resource set (CORESET) 0 for Type 0 physical downlink control channel (PDCCH)). Here, an actual PUSCH repetition can include fewer symbols than a nominal PUSCH repetition.

[0086] After transmitting RRC signaling 210, base station 105-a can transmit DCI 215 that activates a periodic CSI report via a PUSCH transmission. In some cases, DCI 215 can indicate one of the trigger states configured by RRC signaling 210. In some instances, DCI 215 can be scrambled using a semi-persistent channel state information - radio network temporary identifier (SP-CSI-RNTI).

[0087] Based on receiving the DCI 215, the UE 115-a can identify a single CSI report configuration associated with the indicated trigger state. The UE 115-a can additionally identify whether a trigger condition is satisfied that triggers transmission of both the first instance and the second instance of the CSI report 220 within the periodic CSI reporting period 225. If the UE 115-a determines that the trigger condition is satisfied, the UE 115-a can transmit, via the first PUSCH transmission 230 and the second PUSCH transmission 230, the first instance of the CSI report 220 and the second instance of the CSI report 220, respectively, through the transmit beam 205 within each period 225 of the periodic CSI reporting. For example, the UE 115-a can transmit, via the PUSCH transmission 230-a and the PUSCH transmission 230-b, the first instance of the CSI report 220 and the second instance of the CSI report 220, respectively, within the period 225-a. Alternatively, if the UE 115-a determines that the trigger condition is not satisfied, the UE 115-a can transmit a single instance of the CSI report 220 through the transmit beam 205 within each period 225 of the periodic CSI reporting. That is, the UE 115-a can transmit the CSI report 220 via the PUSCH transmissions 230-a, 230-c, and 230-e, and can refrain from transmitting the CSI-report via the PUSCH transmissions 230-b, 230-d, and 230-f.

[0088] In some cases, when the UE 115-a determines that the trigger condition is satisfied, the DCI 215 can indicate two trigger states, each associated with a CSI report configuration. In some cases, the two CSI report configurations can each indicate a different transmit power (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, the UE 115-a can transmit a first instance of the CSI report 220 via a PUSCH transmission 230 using a transmit beam 205-a associated with a first set of sounding reference signal (SRS) resources. Additionally, the UE 115-a can transmit a second instance of the CSI report 220 via a PUSCH transmission 230 using a transmit beam 205-b associated with a second set of SRS resources. Here, the UE 115-a can transmit the first instance of the CSI report 220 using a first transmit power (e.g., indicated by a first trigger state) and the second instance of the CSI report 220 using a second transmit power (e.g., indicated by a second trigger state). In a second example, the UE 115-a can transmit both instances of the CSI report 220 via PUSCH transmissions 230 using the same transmit beam 205 associated with a single set of SRS resources. Here, the UE 115-a can transmit both instances of the CSI report 220 using a single transmit power (e.g., indicated by one of the trigger states).

[0089] In one example, the UE 115-a can determine that the trigger condition is satisfied based on the DCI 215 indicating a first SRS associated with a first PUSCH transmission 230 and a second SRS associated with a second PUSCH transmission 230. For example, the DCI 215 can indicate that the PUSCH transmissions 230-a, 230-c, and 230-e are associated with one set of SRS resources and the PUSCH transmissions 230-b, 230-d, and 230-f are associated with another set of SRS resources. The UE 115-a can then determine that the trigger condition is satisfied and can transmit two instances of the CSI report 220 within each period 225 using the PUSCH transmissions 230 associated with different sets of SRS resources. Here, the UE 115-a can use different transmit beams 205 to transmit the PUSCH transmissions 230 within each period 225. For example, the UE 115-a can use a transmit beam 205-a to transmit the PUSCH transmissions 230 associated with the first set of SRS resources. Additionally, the UE 115-a can use a transmit beam 205-b to transmit the PUSCH transmissions 230 associated with the second set of SRS resources.

[0090] In another example, UE 115-a can determine that the trigger condition is satisfied based on DCI 215 indicating more than one repetition of PUSCH transmission 230. In some cases, DCI 215 can indicate more than two repetitions of PUSCH transmission 230 (e.g., within each period 225). Here, UE 115-a can still transmit two PUSCH transmissions 230 within each period. Additionally or alternatively, UE 115-a can determine that the trigger condition is satisfied based on DCI 215 indicating a trigger state associated with a CSI reporting configuration that indicates both a first and a second instance of CSI reporting. That is, for each trigger state, RRC signaling 210 can additionally indicate whether the trigger state is associated with a single instance of CSI reporting in each period 225 or two instances of CSI reporting in each period 225. In another example, UE 115-a can determine that the trigger condition is satisfied based on DCI 215 including a field (e.g., a single bit within DCI 215) that indicates whether the activated trigger state is associated with a single instance of CSI reporting in each period 225 or two instances of CSI reporting in each period 225.

[0091] Figure 3A and 3B An example PUSCH transmission configuration 300 that supports semi-persistent reporting of CSI is illustrated in accordance with aspects of the present disclosure. For example, PUSCH transmission configuration 300 can illustrate an example PUSCH transmission configuration 300 that includes two PUSCH transmissions 305 transmitted in each period 325 of a periodic CSI report. Additionally, each PUSCH transmission 305 can include an instance of CSI reporting 310. In some examples, PUSCH transmission configuration 300 can implement aspects of wireless communication as described with reference to FIGs. 1-2. Figure 1 and 2 For example, for two PUSCH transmission configurations 300, a base station can configure semi-persistent reporting of CSI (e.g., through RRC signaling, through DCI) including two instances of CSI reporting 310 within each period 325 of a periodic CSI report as described with reference to FIGs. 1-2. Figure 1 and 2 For example, for two PUSCH transmission configurations 300, a base station can configure semi-persistent reporting of CSI (e.g., through RRC signaling, through DCI) including two instances of CSI reporting 310 within each period 325 of a periodic CSI report as described with reference to FIGs. 1-2.

[0092] In the example of PUSCH transmission configuration 300-a, actual PUSCH transmissions 305-a, 305-b, and 305-d can be the same as nominal PUSCH transmissions 305-a, 305-b, and 305-d. Additionally, actual PUSCH transmission 305-c can be different than nominal PUSCH transmission 305-c. For example, the UE can determine that one or more symbols associated with PUSCH transmission 305-c are invalid. Here, the UE can refrain from transmitting PUSCH transmission 305-c within period 325-b. The UE can still transmit PUSCH transmission 305-d within period 325-b (e.g., even in the case that the actual transmission of another PUSCH transmission 305-c within period 325-b is different than the nominal transmission of PUSCH transmission 305-c).

[0093] In the example of PUSCH transmission configuration 300-b, actual PUSCH transmissions 305-e, 305-f, and 305-h can be the same as nominal PUSCH transmissions 305-e, 305-f, and 305-h. Additionally, actual PUSCH transmission 305-g can be different than nominal PUSCH transmission 305-g. For example, the UE can determine that one or more symbols associated with PUSCH transmission 305-g are invalid. Here, the UE can refrain from transmitting PUSCH transmission 305-g within period 325-d. The UE can also refrain from transmitting PUSCH transmission 305-h within period 325-d, even though the actual transmission of PUSCH transmission 305-h is the same as the nominal transmission of PUSCH transmission 305-h. That is, when any of the actual PUSCH transmissions 305 are different than the nominal PUSCH transmissions 305, the UE can not transmit any PUSCH transmissions 305 in period 325.

[0094] Figure 4 An example of a process flow 400 that supports semi-persistent reporting of CSI in accordance with aspects of the present disclosure is illustrated. In some examples, process flow 400 can implement aspects of the Figures 1 to 3B . For example, UE 115-b can be an example of a UE 115 as described with reference to Figures 1 to 3B . Additionally, base station 105-b can be an example of a base station 105 as described with reference to Figures 1 to 3B .

[0095] At 405, base station 105-b can transmit RRC signaling to UE 115-b. For example, UE 115-b can receive RRC signaling indicating a set of trigger states, each trigger state associated with a CSI report configuration.

[0096] At 410, base station 105-b can transmit DCI to UE 115-b. For example, UE 115-b can receive the DCI that activates a periodic CSI report transmitted via an uplink shared channel. In some cases, the DCI can activate the periodic CSI report by indicating one trigger state from a set of trigger states.

[0097] At 415, UE 115-b can identify a trigger condition that triggers transmission of both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report.

[0098] At 420, UE 115-b can determine that the trigger condition is satisfied. In one example, UE 115-b can determine that the trigger condition is satisfied based on the DCI indicating both a first set of SRS resources associated with a first uplink shared channel transmission and a second set of SRS resources associated with a second uplink shared channel transmission. In another example, UE 115-b can determine that the trigger condition is satisfied based on the DCI indicating more than one repetition of an uplink shared channel transmission within a period of the periodic CSI report. In another example, UE 115-b can determine that the trigger condition is satisfied based on one trigger state (e.g., indicated by the DCI) being associated with a CSI report configuration that indicates transmission of both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report. In another example, UE 115-b can determine that the trigger condition is satisfied based on a value of a field within the DCI, the field being configured to indicate transmission of both a first instance of the CSI report and a second instance of the CSI report within a period of the periodic CSI report or transmission of a single CSI report within a period of the periodic CSI report.

[0099] At 425, UE 115-b can transmit, based on the satisfaction of the trigger condition, the first instance of the CSI report via a first uplink shared channel transmission and the second instance of the CSI report via a second uplink shared channel transmission, both within a period of the periodic CSI report. In cases where the DCI indicates two sets of SRS resources associated with the first and second uplink shared channel transmissions, UE 115-b can transmit the first instance of the CSI report via the first uplink shared channel transmission using a first transmit beam associated with the first set of SRS resources. Additionally, UE 115-b can transmit the second instance of the CSI report via the second uplink shared channel transmission using a second transmit beam associated with the second set of SRS resources.

[0100] Figure 5A block diagram 500 of a device 505 that supports semi-persistent reporting of CSI in accordance with aspects of the present disclosure is shown. The device 505 can be an example of aspects of a UE 115 as described herein. The device 505 can include a receiver 510, a transmitter 515, and a communications manager 520. The device 505 can also include a processor. Each of these components can be in communication with one another (e.g., via one or more buses).

[0101] The receiver 510 can provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to semi-persistent reporting of CSI). Information can be passed on to other components of the device 505. The receiver 510 can utilize a single antenna or a set of multiple antennas.

[0102] The transmitter 515 can provide a means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 can transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to semi-persistent reporting of CSI). In some examples, the transmitter 515 can be collocated with the receiver 510 in a transceiver module. The transmitter 515 can utilize a single antenna or a set of multiple antennas.

[0103] The communications manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or various components thereof, can be examples of means for performing various aspects of semi-persistent reporting of CSI as described herein. For example, the communications manager 520, the receiver 510, the transmitter 515, or various combinations or components thereof can support a method for performing one or more of the functions described herein.

[0104] In some examples, the communications manager 520, the receiver 510, the transmitter 515, or various combinations or components thereof can be implemented in hardware (e.g., in communications management circuitry). The hardware can 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, a discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing the functions described in the present disclosure. In some examples, a processor and memory coupled with the processor can be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in memory).

[0105] Additionally, or alternatively, in some examples, the communications manager 520, the receiver 510, the transmitter 515, or various combinations thereof or components thereof, can be implemented by code, e.g., as communications management software or firmware, executed by a processor. If implemented in code executed by a processor, the functions of the communications manager 520, the receiver 510, the transmitter 515, or various combinations thereof or components thereof, can be executed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination of these or other programmable logic devices, e.g., configured as or otherwise supporting a means for performing the functions described in the present disclosure.

[0238] Although aspects of an LTE, LTE-A, LTE-A Pro, or NR system can be described for purposes of example, and LTE, LTE-A, LTE-A Pro, or NR terminology can be used in much of the description, the techniques described herein are applicable beyond LTE, LTE-A, LTE-A Pro, or NR networks. For example, the described techniques can be applicable to various other wireless communication systems, such as Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and others.

[0239] Information and signals described herein can be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that can be referenced throughout the description can be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0240] The various illustrative blocks and components described herein can be implemented or performed with a general-purpose processor, a DSP, an ASIC, a CPU, a FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor can be a microprocessor, but in the alternative, the processor can be any processor, controller, microcontroller, or state machine. A processor can also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0241] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions can also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.

[0242] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another.
