Technical Field

[0003] The following generally relates to wireless communications and, more specifically, to non - periodic channel state information (CSI) physical uplink shared channel (PUSCH) repetition using demodulation reference signal (DMRS) bundling. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi - access systems include fourth - generation (4G) systems such as Long - Term Evolution (LTE) systems, Advanced LTE (LTE - A) systems, or LTE - A Pro systems, and fifth - generation (5G) systems that may be 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 multiple access (DFT - S - OFDM).

[0005] A wireless multi-access communication system can include one or more base stations or one or more network access nodes, each of which supports communication of multiple communication devices simultaneously, and the communication devices can also be referred to as user equipment (UE). Some wireless communication systems such as 4G and 5G systems can support channel state information (CSI) operations. These communication systems can also support demodulation reference signal (DMRS) bundling operations. As the demand for communication efficiency increases, some wireless communication systems may not be able to provide satisfactory CSI operations and DMRS bundling operations, and thus may not support high-reliability or low-latency communication, etc. Summary of the Invention

[0006] Aspects of the described techniques relate to configuring a communication device (which can be a user equipment (UE)) to support providing an aperiodic channel state information (CSI) report on a physical uplink shared channel (PUSCH) in a wireless communication system. The described techniques can be used to configure a communication device with a CSI report configuration (e.g., PUSCH repetition configuration, PUSCH (retransmission) transmission configuration) such that the communication device can extend the PUSCH coverage for aperiodic CSI reporting. Additionally, the described techniques can be used to configure a communication device to support PUSCH DMRS bundling operations for PUSCH repetition or PUSCH (retransmission) transmission or both. Thus, PUSCH DMRS can be provided coherently to the communication device, and the communication device can be configured to determine a channel estimate from the bundled PUSCH DMRS to enhance the channel estimate for PUSCH repetition or PUSCH (retransmission) transmission or both. The communication device can thus be configured to support improvements in CSI operations and DMRS bundling operations in a fifth-generation (5G) system. The described techniques can include features for improving power consumption, and in some examples, can facilitate enhanced efficiency and other benefits for high-reliability and low-latency operations in a 5G system.

[0105] A wireless communication system can include a plurality of communication devices such as a user equipment (UE) and a base station, which can provide wireless communication services to the UE. For example, such a base station can be a next-generation node B or a giga node B (either of which can be referred to as a gNB), which can support multiple radio access technologies (RATs) including fourth-generation (4G) systems such as long-term evolution (LTE) systems and fifth-generation (5G) systems (which can be referred to as new radio (NR) systems). The techniques described can be used to configure a UE with CSI reporting configurations (e.g., PUSCH repetition configuration, PUSCH (retransmission) transmission configuration) such that the UE can extend the PUSCH and PUCCH coverage for aperiodic CSI reporting. For example, the UE can provide an aperiodic CSI report to a base station (e.g., gNB) according to one or more of the PUSCH repetition configuration or the PUSCH (retransmission) transmission configuration. The configuration (e.g., aperiodic CSI PUSCH repetition configuration) can include the number of repetitions and the start of the symbol in each time slot. The start symbol can be at the same position in each time slot (e.g., PUSCH repetition type A) or it can be at different positions in different time slots (e.g., PUSCH repetition type A). In some examples, the techniques described can facilitate configuring a UE to specifically provide an aperiodic CSI report on a PUSCH without a transmission channel such as an uplink shared channel (UL-SCH) based on, for example, a CSI reporting configuration (e.g., PUSCH repetition configuration, PUSCH (retransmission) transmission configuration).

[0106] The described techniques may also be used to configure a UE to support DMRS bundling operations for physical uplink channels (e.g., PUSCH, PUCCH) for physical uplink channel repetition or (retransmission) transmissions (e.g., PUSCH repetition, PUSCH (retransmission) transmission, PUCCH repetition, PUCCH (retransmission) transmission) or both. For example, the described techniques may be used to configure a UE to support PUSCH DMRS bundling operations for one or more hops in a time-domain hopping pattern or a frequency-domain hopping pattern related to PUSCH repetition or PUSCH (retransmission) transmission. In some examples, the described techniques may facilitate configuring a UE to support PUSCH DMRS bundling operations by providing signaling including an indication of the number of symbols, mini-slots, or slots, or any combination thereof, of the PUSCH for each hop, or the number of PUSCH DMRS symbols to be bundled in each hop. Thus, PUSCH DMRS may be provided coherently to the UE, and the UE may be configured to determine channel estimates based on the bundled PUSCH DMRS to enhance channel estimates for PUSCH repetition or PUSCH (retransmission) transmission or both. The UE may thus be configured to support improvements in CSI operations and DMRS bundling operations in a 5G system. The described techniques may include features for improving power consumption and, in some examples, may facilitate enhanced efficiency and other benefits for high-reliability and low-latency operations in a 5G system.

[0107] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described with reference to a processing flow and CSI reporting configuration related to PUSCH repetition utilizing DMRS bundling. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts related to PUSCH repetition utilizing DMRS bundling.

[0108] Figure 1 An example of a wireless communication system 100 that supports PUSCH repetition utilizing DMRS bundling in accordance with aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In certain 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 enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0109] Base stations 105 can be dispersed throughout a geographic area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and the UEs 115 and the base stations 105 can establish one or more communication links 125 over the coverage area 110. The coverage area 110 can be an example of a geographic area over which the base stations 105 and the UEs 115 can support communication of signals according to one or more radio access technologies.

[0110] The UEs 115 can be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, or mobile, or both at different times. The UEs 115 can be devices of different forms or with different capabilities. Figure 1 Some example UEs 115 are shown. The UEs 115 described herein can be capable of communicating with various types of devices, such as Figure 1 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.

[0111] The base stations 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or another interface). The base stations 105 can communicate with each other directly (e.g., directly between base stations 105), or indirectly (e.g., via the core network 130), or both, via the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or include one or more wireless links. One or more of the base stations 105 described herein can include or can be referred to by those of ordinary skill in the art as base transceiver stations, radio base stations, access points, radio transceivers, NodeB, eNodeB (eNB), next-generation NodeB, or gigabit NodeB (any of which can be referred to as gNB), home NodeB, home eNodeB, or other suitable terms.

[0112] The UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where "device" may also be referred to as unit, station, terminal, client, and other examples. The UE 115 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, the UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances, or vehicles, meters, etc.

[0113] The UE 115 described herein may be capable of communicating with various types of devices, such as Figure 1 other UEs 115 that may sometimes act as relays as shown, as well as the base station 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations. The UE 115 and the base station 105 may communicate wirelessly 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 spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion (e.g., bandwidth part (BWP)) of a radio frequency spectrum band operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0114] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)), and may be positioned according to a channel raster for discovery by the UE 115. A carrier may operate in an independent mode, where initial acquisition and connection may be made by the UE 115 via the carrier, or a carrier may operate in a non-independent mode, where a connection is anchored using a different carrier (e.g., having the same or different radio access technology). A communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communication (e.g., in an FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in a TDD mode).

[0115] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., the base station 105 or the UE 115 or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with a plurality of carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

[0116] The signal waveform transmitted on a carrier can be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system adopting MCM techniques, a resource element can be composed of a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding and decoding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate for UE 115 may be. Wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beamforming), and using multiple spatial layers can also increase the data rate or data integrity for communicating with UE 115.

[0117] One or more numerologies can be supported for a carrier, where a numerology can include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different numerologies. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and the communication of UE 115 can be restricted to one or more active BWPs. The time interval for the base station 105 or UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can refer to, for example, T s = 1 / (Δf max ·N f ) seconds of sampling period, where Δf max can represent the maximum supported subcarrier spacing, and N f can represent the maximum supported discrete Fourier transform (DFT) size. The time interval of the communication resources can be organized according to each radio frame 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).

[0118] Each frame may include a plurality of consecutively numbered sub-frames or time slots, and each sub-frame or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into sub-frames, and each sub-frame may be further divided into a plurality of 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 a plurality of symbol periods (e.g., depending on the length of the cyclic prefix before each symbol period). In some wireless communication systems 100, a time slot may also be divided into a plurality of mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band. A sub-frame, time slot, mini-slot, or symbol may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain), and may 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) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0119] Physical channels may be multiplexed on a carrier according to various techniques. For example, time-division multiplexing (TDM) techniques, frequency-division multiplexing (FDM) techniques, or one or more of hybrid TDM-FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a plurality of symbol periods and may extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information of a control information format having a given payload size. A search space set may include a common search space set configured to send control information to a plurality of UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0120] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity for communicating with the base station 105 (e.g., via a carrier), and may be associated with an identifier for differentiating neighboring cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of the geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the base station 105, the ranges of these cells can vary from relatively small areas (e.g., a structure, a subset of a structure) to relatively large areas. For example, a cell may be or include a building, a subset of a building, or an exterior space between or overlapping with the geographic coverage area 110, etc.

[0121] Macro cells typically cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs 115 having a service subscription with the network provider that supports the macro cell. In comparison with macro cells, small cells may be associated with low-power base stations 105, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 having a service subscription with the network provider, or may provide restricted access to UEs 115 having an association with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers. In some examples, a carrier may support multiple cells and may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access for different types of devices.

[0122] In some examples, the base station 105 may be movable and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0123] The wireless communication system 100 may support synchronous or asynchronous operations. For synchronous operations, the base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operations, the base stations 105 may have different frame timings, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operations.

[0124] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices integrated with sensors or meters to measure or capture information and relay this information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Example applications of MTC devices include smart metering, inventory monitoring, water level monitoring, device monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging.

[0125] Some UEs 115 may be configured to operate in power-saving modes, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not both simultaneously). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a deep sleep power-saving mode when not participating in active communication, or operating over a bandwidth (e.g., according to narrowband communication) or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type associated with a defined portion or range within a carrier, within a guard band of the carrier, or outside the carrier (e.g., a set of subcarriers or resource blocks (RBs)).

[0126] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication 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 prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0127] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 via 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 communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may 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, the base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UEs 115 without the participation of the base station 105.

[0128] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information about traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure such as roadside units, or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.

[0129] 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 a 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 to or interconnects with an external network (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 can manage non-access stratum (NAS) functions, such as the mobility, authentication, and bearer management of the UE 115 served by the base station 105 associated with the core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to the network operator IP service 150. The operator IP service 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0130] Some network devices, such as the base station 105, can include subcomponents such as the access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with the UE 115 through one or more other access network transmission entities 145, which can be referred to as radio heads, intelligent radio heads, or transmit / receive points (TRPs). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, the 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., the base station 105).

[0131] The wireless communication system 100 can operate using one or more frequency bands generally 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 the decimeter band because the wavelength range is approximately from 1 decimeter to 1 meter. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable a macro cell to serve the UE 115 located indoors. Compared with transmissions at smaller frequencies and longer wavelengths using the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers).

[0132] The wireless communication system 100 may also operate in the super high frequency (SHF) region (also known as the centimeter band) using a frequency band from 3 GHz to 30 GHz or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the respective devices may be smaller and closer spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the devices. However, the propagation of EHF transmissions may experience even greater atmospheric attenuation and shorter ranges than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory body.

[0133] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency 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 an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency band, devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in the unlicensed band may be based on a carrier aggregation configuration combined with a component carrier operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, among others.

[0134] The base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna fixture such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array with antenna ports arranged in multiple rows and columns, and the base station 105 may use this antenna array to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0135] The base station 105 or the UE 115 can use MIMO communication to utilize multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique can be referred to as spatial multiplexing. The multiple signals can be transmitted, for example, by the transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device and multi-user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.

[0136] 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., the base station 105, the UE 115) to shape or manipulate an antenna beam (e.g., a transmit beam, a receive beam) along the spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via the antenna elements of an antenna array such that some signals propagating in a particular azimuth relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals communicated via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustment associated with each antenna element can be defined by a set of beamforming weights associated with a particular azimuth (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other azimuth).

[0137] The base station 105 or the UE 115 can use beam scanning techniques as part of the beamforming operation. For example, the base station 105 can use multiple antennas or an antenna array (e.g., an antenna panel) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted by the base station 105 multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by a transmitting device such as the base station 105 or a receiving device such as the UE 115) to identify a beam direction for later transmission or reception by the base station 105.

[0138] Some signals, such as data signals associated with a specific receiving device, can be transmitted by the base station 105 in a single beam direction (e.g., the direction associated with a receiving device such as the UE 115). In some examples, the beam direction associated with a transmission along a single beam direction can be determined based on the signals transmitted in one or more beam directions. For example, the UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions, and the UE 115 can report to the base station 105 an indication of the signal that it has received with the highest signal quality or other acceptable signal quality.

[0139] In some examples, transmissions performed by a device (e.g., by the base station 105 or the UE 115) can be carried out 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 the base station 105 to the UE 115). The UE 115 can report feedback indicating precoding weights for one or more beam directions, and the feedback can correspond to the configured number of beams across the system bandwidth or one or more sub-bands. The base station 105 can transmit reference signals that can be precoded or not precoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). The UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by the base station 105 in one or more directions, the UE 115 can employ similar techniques to transmit signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by the UE 115), or to transmit signals in a single direction (e.g., for transmitting data to a receiving device).

[0140] The UE 115 can receive signaling including CSI reporting configuration. The UE 115 can determine one or more resources of the physical uplink channel for aperiodic CSI reporting based on the CSI reporting configuration, and transmit an aperiodic CSI report via the physical uplink channel based on the one or more resources. In some examples, the UE 115 can also determine a set of DMRS symbols associated with jumps in a set of jumps in the time domain or frequency domain, and bundle the set of DMRS symbols associated with the jumps in the set of jumps based on this determination.

[0141] When receiving various signals such as synchronization signals, reference signals, beam selection signals, or other control signals from base station 105, a receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening). For example, the receiving device may attempt multiple receive directions by receiving via different antenna sub-arrays, processing received signals according to different antenna sub-arrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array. Any of the above methods may be referred to as "listening" according to different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction with the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality determined based on listening according to multiple beam directions).

[0142] Wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly for communication on logical channels. The media access control (MAC) layer may perform priority handling and multiplex logical channels onto transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support (retransmission) transmissions at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection between UE 115 and base station 105 or core network 130, and core network 130 supports radio bearers for user plane data. At the physical layer, transport channels may be mapped to physical channels.

[0143] UE 115 and base station 105 may support (re)transmission of data to increase the likelihood of successful data reception. Hybrid automatic repeat request (HARQ) feedback is a technique that increases the likelihood of correctly receiving data over communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and (re)transmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0144] Figure 2 An example of a wireless communication system 200 that supports PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure is shown. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100. For example, wireless communication system 200 may include base station 105 and UE 115 within geographical coverage area 110. Base station 105 and UE 115 may be examples of the corresponding devices described with reference to Figure 1 In some examples, wireless communication system 200 may support multiple RATs, including 4G systems such as LTE systems, LTE-A systems, or LTE-A Pro systems and 5G systems that may be referred to as NR systems. Wireless communication system 200 may support improvements in power consumption, spectral efficiency, higher data rates, and in some examples, may facilitate enhanced efficiency and other benefits for high-reliability and low-latency CSI operations as well as DMRS bundling operations.

[0145] The base station 105 and the UE 115 may be configured with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output communication, or beamforming, or any combination thereof. The antennas of the base station 105 and the UE 115 may be located within one or more antenna arrays or antenna panels, which may support multiple-input multiple-output operations, or transmit or receive beamforming. For example, the base station 105 antennas or antenna arrays may be co-located at an antenna fixture such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array with multiple rows and columns of antenna ports, and the base station 105 may use the antenna array to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various multiple-input multiple-output or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via one or more antenna ports. The base station 105 and the UE 115 may thus be configured to support directional communication using multiple antennas.

[0146] The UE 115 in the wireless communication system 200 may support CSI operations to conserve resources (e.g., time and frequency resources of the wireless communication system 200), the battery life of the UE 115, etc. In some examples, the UE 115 may be configured to support CSI operations to manage or improve directional communication between the base station 105 and the UE 115. The CSI operations may include providing a CSI report 205 to the base station 105. The CSI report 205 may include one or more CSI parameters. In some examples, the UE 115 may generate the CSI report 205 including more than one CSI parameter based on measuring one or more reference signals, such as a synchronization signal physical broadcast channel (SS / PBCH) block (SSB) or a CSI reference signal (CSI-RS) from the base station 105. For example, the base station 105 may transmit one or more SSBs or CSI-RSs via the directional communication 210 between the base station 105 and the UE 115, and the UE 115 may receive one or more SSBs or CSI-RSs.

[0147] One or more CSI parameters may include one or more of a channel quality indicator (CQI), a precoding matrix indicator (PMI), or a CSI reference signal (CSI-RS) indicator (CRI). In some other examples, one or more CSI parameters may additionally or alternatively include one or more of a synchronization signal physical broadcast channel (SS / PBCH) block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI), or a layer one reference signal received power (L1-RSRP). In some examples, UE 115 may determine the LI based in part on the CQI, PMI, RI, or CRI, or any combination thereof. In some examples, UE 115 may determine the CQI based in part on the PMI, RI, or CRI, or any combination thereof. In some examples, UE 115 may determine the PMI based in part on the RI or CRI, or both. UE 115 may determine the RI based in part on the CRI.

[0148] UE 115 may transmit the CSI report 205 via the directed communication 210. The directed communication 210 may include providing the CSI report 205 on one or more physical channels such as a PUSCH, a physical uplink control channel (PUCCH), etc. In some examples, the base station 105 may configure UE 115 with a CSI report configuration. In some examples, the CSI report 205 may be an aperiodic CSI report, and UE 115 may transmit the aperiodic CSI report on the PUSCH according to the CSI report configuration. In some examples, the CSI report 205 may be a periodic CSI report, and UE 115 may transmit the periodic CSI report using the PUCCH according to the CSI report configuration. Alternatively, the CSI report 205 may be a semi-persistent CSI report, and UE 115 may transmit the semi-persistent CSI report using the PUCCH or a PUSCH activated by downlink control information (DCI) according to the CSI report configuration. Refer to Figure 3 examples describing aperiodic CSI reports, and refer to Figure 4 examples describing periodic CSI reports.

[0149] Figure 3 FIG. shows an example of a processing flow 300 supporting aperiodic CSI reporting according to aspects of the present disclosure. The processing flow 300 may implement aspects of the wireless communication systems 100 and 200 described respectively with reference to Figure 1 and Figure 2 For example, the processing flow 300 may be based on the configuration of the base station 105 or UE 115 and implemented by UE 115. The base station 105 and UE 115 may be as described with reference to Figure 1 and Figure 2Examples of the described base station and UE. In the following description of process flow 300, the operations between base station 105 and UE 115 may be sent in an order different from the order of the illustrated examples, or the operations performed by base station 105 and UE 115 may be performed in a different order or at different times. Certain operations may also be omitted from process flow 300, and other operations may be added to process flow 300.

[0150] At 305, base station 105 may send a CSI report configuration to UE 115. For example, base station 105 may send the CSI report configuration via directed communication. Directed communication may include a random access channel (RACH), a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), etc. In some examples, base station 105 may send the CSI report configuration via radio resource control (RRC) signaling. Thus, the CSI report configuration may be provided in an RRC configuration message, which may include one or more parameters (e.g., information elements) for configuring UE 115 for CSI reporting. For example, the parameter may configure UE 115 to support aperiodic CSI reporting. In other words, the parameter may indicate the CSI report type of UE 115. In some other examples, the parameter may indicate the time or frequency resource or both used by UE 115 for aperiodic CSI reporting.

[0151] At 310, base station 105 may send a control message to UE 115. In some examples, the control message may be downlink control information (DCI). In some other examples, the control message may be a medium access control (MAC) control element (CE) (MAC-CE). Base station 105 may include a trigger for aperiodic CSI reporting in the control message. That is, the CSI report configuration may be activated or deactivated based on the trigger in the control message. Thus, UE 115 may activate or deactivate the CSI report configuration based on the trigger in the control message.

[0152] At 315, base station 105 may send one or more reference signals to UE 115. For example, base station 105 may send one or more CSI-RSs or one or more SSBs to UE 115 via directed communication as described in Figure 1 and Figure 2 . In some examples, there may be a gap 325, e.g., a timing gap between 310 and 315. Gap 325 may include more than one symbol, mini-slot, or slot. Thus, base station 105 may send one or more reference signals to UE 115 after one or more symbols, mini-slots, or slots after sending the control message to UE 115. As referenced in Figure 2As described, UE 115 may determine one or more CSI parameters based on one or more received reference signals. For example, UE 115 may determine one or more of CQI, PMI, or CRI. In some other examples, UE 115 may additionally or alternatively determine one or more of SSBRI, LI, RI, or L1-RSRP.

[0153] At 325, UE 115 may send an aperiodic CSI report to base station 105. UE 115 may send the aperiodic CSI report to base station 105 via directed communication as Figure 1 and Figure 2 described. For example, UE 115 may send the aperiodic CSI report on PUSCH via directed communication. In some examples, there may be a gap 330, e.g., a timing gap between 310 and 325. Gap 330 may include more than one symbol, mini-slot, or slot. Thus, UE 115 may send the aperiodic CSI report to base station 105 on PUSCH after one or more symbols, mini-slots, or slots after receiving a control message from base station 105.

[0154] Figure 4 FIG. shows an example of a processing flow 400 that supports periodic CSI reporting in accordance with aspects of the present disclosure. Processing flow 400 may implement aspects of wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. For example, processing flow 400 may be implemented by UE 115 based on the configuration of base station 105 or UE 115. Base station 105 and UE 115 may be examples of base stations and UEs as described with reference to Figure 1 and Figure 2 In the following description of processing flow 400, operations between base station 105 and UE 115 may be sent in an order different from the illustrated example order, or operations performed by base station 105 and UE 115 may be performed in a different order or at different times. Certain operations may also be omitted from processing flow 400, and other operations may be added to processing flow 400.

[0155] At 405, the base station 105 may send a CSI report configuration to the UE 115. For example, the base station 105 may send the CSI report configuration via directed communication. The directed communication may include RACH, PDCCH, PDSCH, etc. In some examples, the base station 105 may send the CSI report configuration via RRC signaling. Thus, the CSI report configuration may be provided in an RRC configuration message, which may include one or more parameters (e.g., information elements) for configuring the UE 115 for CSI reporting. For example, the parameter may configure the UE 115 to support periodic CSI reporting. In other words, the parameter may indicate the CSI report type of the UE 115. In some other examples, the parameter may indicate the time or frequency resources or both used by the UE 115 for periodic CSI reporting.

[0156] At 410, the base station 105 may send one or more reference signals to the UE 115. For example, the base station 105 may send one or more CSI-RSs or one or more SSBs to the UE 115 via directed communication as described in Figure 1 and Figure 2 . As described in reference Figure 2 , the UE 115 may determine one or more CSI parameters based on the received one or more reference signals. For example, the UE 115 may determine one or more of CQI, PMI, or CRI. In some other examples, the UE 115 may additionally or alternatively determine one or more of SSBRI, LI, RI, or L1-RSRP. At 415, the UE 115 may send a periodic CSI report to the base station 105. The UE 115 may send the periodic CSI report to the base station 105 via directed communication as described in Figure 1 and Figure 2 . For example, the UE 115 may send the periodic CSI report on the PUCCH via directed communication.

[0157] At 420, the base station 105 may send one or more reference signals to the UE 115 again. For example, the base station 105 may send one or more CSI-RSs or one or more SSBs to the UE 115 via directed communication as described in Figure 1 and Figure 2 . As described in reference Figure 2 , the UE 115 may determine one or more CSI parameters based on the received one or more reference signals. At 425, the UE 115 may send a periodic CSI report to the base station 105 again. The UE 115 may send the periodic CSI report to the base station 105 as described in Figure 1 and Figure 2The periodic CSI report is sent to the base station 105 via directed communication as described. For example, the UE 115 may send the periodic CSI report on the PUCCH via directed communication.

[0158] In some examples, there may be a gap 430, e.g., a timing gap between 410 and 420. The gap 430 may include more than one symbol, mini-slot, or slot. In Figure 4 the example of, the timing gap may be periodic. Thus, the base station 105 may send one or more reference signals to the UE 115 based on the periodicity of one or more symbols, mini-slots, or slots. Similarly, in some examples, there may be a gap 435, e.g., a timing gap between 415 and 425. The gap 435 may include more than one symbol, mini-slot, or slot. In Figure 4 the example of, the timing gap may be periodic. Thus, the UE 115 may send the periodic CSI report to the base station 105 based on the periodicity such as one or more symbols, mini-slots, or slots.

[0159] Returning to Figure 2 , in some examples, the CSI report 205 may be an aperiodic CSI report, and the UE 115 may send the aperiodic CSI report on the PUSCH according to the CSI report configuration. The PUSCH may carry the aperiodic CSI report specifically (i.e., without an uplink shared channel (UL-SCH)). In some other examples, the PUSCH may alternatively carry both the aperiodic CSI report and the UL-SCH. In certain cases, when the PUSCH carries the aperiodic CSI report, the wireless communication system 200 may not support PUSCH repetition and PUSCH (retransmission) transmission (i.e., hybrid automatic repeat request (HARQ)). Thus, the UE 115 may experience reduced coverage of the PUSCH. As the demand for communication efficiency increases, the wireless communication system 200 may extend the PUSCH coverage for the UE 115. To extend the PUSCH coverage for the UE 115, the base station 105 may configure the UE 115 to support PUSCH repetition or PUSCH (retransmission) transmission or both for the PUSCH carrying the aperiodic CSI report.

[0160] For example, the base station 105 may transmit CSI report configurations, which may include a PUSCH repetition configuration or a PUSCH (retransmission) transmission configuration or one or more of both that support aperiodic CSI reporting. The base station 105 may transmit the CSI report configuration via signaling such as RRC signaling, DCI signaling, or MAC-CE signaling, and the UE 115 may receive the CSI report configuration via signaling such as RRC signaling, DCI signaling, or MAC-CE signaling. The UE 115 may determine one or more resources for the PUSCH for aperiodic CSI reporting based on the CSI report configuration. For example, the UE 115 may determine one or more resources for the PUSCH for aperiodic CSI reporting based on the PUSCH repetition configuration. In some examples, the UE 115 may determine PUSCH repetition based on the PUSCH repetition configuration. PUSCH repetition may include the repetition of one or more PUSCHs on one or more resources.

[0161] One or more resources may include symbols, mini-slots, or slots or any combination thereof. In some examples, the repetition of one or more PUSCHs on one or more resources may be continuous or discontinuous. The UE 115 may transmit the CSI report 205 (e.g., aperiodic CSI report) according to the PUSCH repetition. In some examples, when the repetition of the PUSCH configured to carry the CSI report 205 (e.g., aperiodic CSI report) is configured, the PUSCH may carry the CSI report 205 (e.g., aperiodic CSI report) specifically without carrying the UL-SCH. Refer to Figure 5 Describe an example of continuous PUSCH repetition related to aperiodic CSI reporting, and refer to Figure 6 Describe an example of discontinuous PUSCH repetition related to periodic CSI reporting.

[0162] Figure 5 FIG. 500 shows an example of a block diagram that supports PUSCH repetition using DMRS bundling according to aspects of the present disclosure. The block diagram 500 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 500 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 500 may be based on the configuration of the base station 105 or the UE 115 and implemented by the UE 115. In Figure 5In the example shown, block diagram 500 is applicable to implementations or instances when UE 115 is configured with CSI operations, such as non-periodic CSI reporting for PUSCH repetition in a 5G system. For example, block diagram 500 may include one or more PUSCHs 505, which may correspond to time resources (e.g., symbol duration, micro-slot duration, slot duration, sub-frame duration, frame duration) and frequency resources (e.g., sub-carriers, carriers).

[0163] Reference Figure 2 and Figure 5 , when repetition of PUSCHs for carrying non-periodic CSI is configured, the repetition of multiple PUSCHs 505 may be back-to-back in the time domain. For example, the repetition of multiple PUSCHs 505 may be continuous on a micro-slot. In other words, each PUSCH 505 may be associated with a separate micro-slot, where each separate micro-slot corresponding to a different PUSCH 505 is continuous in the time domain. In other examples, the repetition of multiple PUSCHs 505 may be continuous on a slot. Thus, the repetition of multiple PUSCHs 505 may be micro-slot-based or slot-based. In some other examples, the repetition of multiple PUSCHs 505 may be symbol-based.

[0164] Figure 6 An example of block diagram 600 supporting PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure is shown. Block diagram 600 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. Block diagram 600 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. Block diagram 600 may be based on the configuration of base station 105 or UE 115 and be implemented by UE 115. In Figure 6 the example shown, block diagram 600 is applicable to implementations or instances when UE 115 is configured with CSI operations, such as non-periodic CSI reporting for PUSCH repetition in a 5G system. For example, block diagram 600 may include one or more PUSCHs 605, which may correspond to time resources (e.g., symbol duration, micro-slot duration, slot duration, sub-frame duration, frame duration) and frequency resources (e.g., sub-carriers, carriers).

[0165] In some examples, with reference to Figure 2 and Figure 6, when repetition of the PUSCH for carrying non-periodic CSI reports is configured, the repetitions of multiple PUSCHs 605 may not be back-to-back in the time domain. For example, the repetitions of multiple PUSCHs 605 may be discontinuous on mini-slots. In other words, each PUSCH 605 may be associated with a separate mini-slot, where each separate mini-slot corresponding to a different PUSCH 605 is discontinuous in the time domain. For example, there may be at least one mini-slot between each PUSCH 605. In other examples, the repetitions of multiple PUSCHs 605 may be discontinuous on slots. Thus, the repetitions of multiple PUSCHs 605 may be mini-slot-based or slot-based. In some other examples, the repetitions of multiple PUSCHs 605 may be symbol-based.

[0166] Return to Figure 2 , in some examples, the base station 105 may separately configure the UE 115 for non-periodic CSI reporting, periodic CSI reporting, and semi-persistent CSI reporting for PUSCH repetition. For example, the base station 105 may configure the UE 115 to specifically support PUSCH repetition for non-periodic CSI reporting. In other words, the UE 115 may not be configured to support PUSCH repetition for periodic CSI reporting and semi-persistent CSI reporting. In some examples, the base station 105 may configure the UE 115 to manage (e.g., control) non-periodic CSI reporting for PUSCH repetition based on a threshold. For example, the base station 105 may configure a coding rate threshold (e.g., maximum coding rate) for non-periodic CSI reporting. Thus, if the UE 115 determines that the CSI report 205 (e.g., non-periodic CSI report) meets the coding rate threshold, the UE 115 may support PUSCH repetition for non-periodic CSI reporting.

[0167] For example, the UE 115 may determine the payload size associated with the CSI report 205 (e.g., non-periodic CSI report) and determine that the payload size meets the coding rate threshold. In some examples, the UE 115 may determine a quotient by dividing the payload size by another factor such as resources, modulation order, etc., and determine whether the quotient meets the coding rate threshold. If the quotient meets the coding rate threshold, the UE 115 may support PUSCH repetition for non-periodic CSI reporting. Otherwise, the UE 115 may avoid applying PUSCH repetition to the non-periodic CSI report.

[0168] In some examples, the base station 105 may configure the UE 115 to manage (e.g., control) an aperiodic CSI report for PUSCH repetition based on a semi-static configuration (e.g., an RRC configuration message). For example, the base station 105 may send and the UE 115 may receive a bit indication in the RRC configuration message. The UE 115 may determine the number of component carriers for transmitting a CSI report (e.g., an aperiodic CSI report) and a repetition factor associated with the CSI report. In some examples, the bit indication may be a multi-bit indication to support indication of various component carriers when the UE 115 is configured with uplink carrier aggregation. Refer to Figure 7 and Figure 8 Describe examples of selecting a PUSCH to transmit an aperiodic CSI report.

[0169] Figure 7 FIG. 700 shows an example of a block diagram supporting PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure. The block diagram 700 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 700 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 700 may be based on the configuration of the base station 105 or the UE 115 and implemented by the UE 115. In the Figure 7 example shown, the block diagram 700 is applicable to implementations or instances when the UE 115 is configured with CSI operations (such as an aperiodic CSI report for PUSCH repetition in a 5G system) and configured with uplink carrier aggregation. For example, according to the carrier aggregation configuration, the UE 115 may be configured with multiple uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers. In the Figure 7 example shown, the block diagram 700 may include one or more uplink component carriers, such as uplink component carriers 710 to 745.

[0170] In some cases, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant, which may include an indication of a component carrier and corresponding time and frequency resources for a PUSCH that carries an aperiodic CSI report. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 705, which may include an indication of an uplink component carrier 710. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 715, which may include an indication of a component carrier 720. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 725, which may include an indication of a component carrier 730 and corresponding resources for a PUSCH that carries an aperiodic CSI report 735. Here, the DCI may include an additional indication of the corresponding resources for the PUSCH that carries the aperiodic CSI report 735. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 740, which may include an indication of a component carrier 745. One or more of the uplink component carriers 710, 720, or 745 may be used for other reports, such as periodic CSI reports. In some examples, for a periodic CSI report or a semi-persistent CSI report, the UE 115 may select a component carrier for PUCCH or PUSCH or both based on a component carrier index (e.g., the lowest component carrier index).

[0171] Figure 8 FIG. 800 illustrates an example of a block diagram 800 that supports PUSCH repetition with DMRS bundling in accordance with aspects of the present disclosure. The block diagram 800 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 800 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. The block diagram 800 may be implemented by the UE 115 based on the configuration of the base station 105 or the UE 115. In the example shown in Figure 8 , the block diagram 800 is applicable to implementations or instances when the UE 115 is configured with CSI operations (such as aperiodic CSI reporting for PUSCH repetition in a 5G system) and is configured with uplink carrier aggregation. For example, according to the carrier aggregation configuration, the UE 115 may be configured with multiple uplink component carriers. Carrier aggregation may be used with both FDD and TDD component carriers.

[0172] In Figure 8In the example shown, the block diagram 800 may include one or more uplink component carriers, such as uplink component carriers 810 to 850. In some cases, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant, which may include an indication of the component carrier and the corresponding time and frequency resources for the PUSCH used to carry the aperiodic CSI report. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 805, which may include an indication of the uplink component carrier 810. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 815-a, which may include an indication of the component carrier 820. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 830-a, which may include an indication of the component carrier 730 and the corresponding resources for the PUSCH used to carry the aperiodic CSI report 840. Here, the DCI may include an additional indication of the corresponding resources for the PUSCH used to carry the aperiodic CSI report 840. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 845, which may include an indication of the component carrier 850.

[0173] In some examples, referring to Figure 2 and Figure 8 , when repetition of the PUSCH for carrying the aperiodic CSI report is configured, the UE 115 may support all PUSCH repetitions carrying the aperiodic CSI report on the same indicated component carrier. In some other examples, when repetition of the PUSCH for carrying the aperiodic CSI report is configured, the UE 115 may support PUSCH repetitions carrying the aperiodic CSI report on different component carriers. The base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 815-b, which may include an indication of the component carrier 820 and the corresponding resources for the PUSCH used to carry the aperiodic CSI report 825. Here, the DCI may include an additional indication of the corresponding resources for the PUSCH used to carry the aperiodic CSI report 825. In some examples, the base station 105 may send via DCI and the UE 115 may receive via DCI an uplink grant 830-b, which may include an indication of the component carrier 820. Thus, in some examples, some PUSCH repetitions may be on a first component carrier over consecutive time slots, while the remainder of the PUSCH repetitions may be on a second component carrier different from the first component carrier. Alternatively, the PUSCH repetitions may be sent on different component carriers for each consecutive time slot.

[0174] Return Figure 2 , in some examples, the UE 115 may be configured to support (re)transmission of a PUSCH for carrying a CSI report 205 (e.g., an aperiodic CSI report). For example, the UE 115 may be configured to use a component carrier for both sending an aperiodic CSI report (e.g., triggering an aperiodic CSI report) on a PUSCH based on DCI indication and re-sending the aperiodic CSI report on the PUSCH. In other examples, the UE 115 may be configured to use a component carrier for sending an aperiodic CSI report (e.g., triggering an aperiodic CSI report) on a PUSCH based on DCI indication and use another component carrier for re-sending the aperiodic CSI report on the PUSCH. The selection of the component carrier for sending an aperiodic CSI report via a PUSCH may be per micro-slot or slot, or transmission-based.

[0175] In some examples, the PUSCH repetition level (e.g., the number of PUSCH repetitions) may be based on the quality of a downlink reference signal. The quality may be a reference signal received power (RSRP) or a reference signal received quality (RSRQ). The downlink reference signal may include but is not limited to a CSI-RS or a synchronization signal physical broadcast channel (SS / PBCH). Thus, the UE 115 may determine one or more of the RSRP or RSRQ of the CSI-RS or SS / PBCH and determine the PUSCH repetition level based on one or more of the RSRP or RSRQ of the CSI-RS or SS / PBCH. If one or more of the RSRP or RSRQ of the CSI-RS or SS / PBCH meet a threshold (e.g., are greater than a predefined threshold), the UE 115 may not support PUSCH repetition. Otherwise, the UE 115 may support PUSCH repetition. In some examples, the PUSCH repetition level may be per micro-slot or slot, or transmission-based.

[0176] In some examples, the base station 105 may configure the UE 115 to support PUSCH DMRS bundling operations for PUSCH repetition or PUSCH (re)transmission or both. For example, the UE 115 may be configured to support PUSCH DMRS bundling operations for each hop in a time-domain hopping pattern or a frequency-domain hopping pattern related to PUSCH repetition or PUSCH (re)transmission. As a result, the UE 115 may bundle the PUSCH DMRSs of PUSCHs belonging to the same hop. As described, the term bundling (also referred to as transmitting coherently) may be defined as the coherent transmission of a PUSCH over multiple PUSCH transmissions. To have such a coherent transmission, phase continuity must be maintained over multiple PUSCH transmissions. Refer toFigure 9 and Figure 10 describes examples of PUSCH DMRS bundling operations related to PUSCH repetition or PUSCH (retransmission) transmissions or both.

[0177] Figure 9 shows an example of block diagram 900 supporting PUSCH repetition utilizing DMRS bundling in accordance with aspects of the present disclosure. Block diagram 900 may implement aspects of the wireless communication systems 100 and 200 respectively referenced Figure 1 and Figure 2 described. Block diagram 900 may implement aspects of the wireless communication systems 100 and 200 respectively referenced Figure 1 and Figure 2 described. Block diagram 900 may be based on the configuration of base station 105 or UE 115 and implemented by UE 115. In the Figure 9 example shown, block diagram 900 is applicable to implementations or instances when UE 115 is configured with PUSCH DMRS bundling operations to support PUSCH repetition or PUSCH (retransmission) transmissions or both. For example, block diagram 900 may include one or more DMRS 905 and one or more PUSCH 910, which may correspond to time resources (e.g., symbol duration, mini-slot duration, slot duration, subframe duration, frame duration) as well as frequency resources (e.g., subcarriers, carriers). For example, DMRS 905 and PUSCH 910 may span a mini-slot duration or a slot duration (e.g., mini-slot / slot 915). In the Figure 9 example, one or more PUSCH 910 may illustrate PUSCH repetition.

[0178] Refer to Figure 2, the base station 105 may configure the UE 115 to support PUSCH DMRS coherent transmission in the time domain. For example, the UE 115 may bundle more than one DMRS 905 in the time domain (e.g., on the mini-slot / slot 915). By coherently transmitting one or more DMRS 905 in the time domain, the base station 105 may transmit the DMR 905 with the same carrier phase continuity and the same phase continuity of the precoding matrix or at least the same phase continuity of the precoding matrix. Thus, the DMRS 905 may be transmitted coherently at different time instants. In some examples, the PUSCH phase continuity may result from discontinuous time resource allocation. The discontinuous time resource allocation may involve a timing gap, which may be greater than or equal to a threshold for PUSCH symbols. Other uplink channels (e.g., PUCCH), signals (e.g., sounding reference signal (SRS), etc.) or downlink channels or signals (e.g., PDCCH, PDSCH, SSB, CSI-RS, etc.) may be transmitted during the timing gap. In some other examples, the PUSCH phase continuity may result from different frequency resource allocations for PUSCH symbols. In other examples, the PUSCH phase continuity may be attributed to the transmission power or the transmission waveform.

[0179] The UE 115 may determine the channel estimates of the DMRS 905 from different time instants by coherently combining the channel estimates to improve the channel estimates. In some examples, the UE 115 may support PUSCH DMRS bundling for PUSCH repetition over multiple mini-slots or slots. In some other examples, the UE 115 may support PUSCH DMRS bundling for PUSCHs carrying different transport blocks (TBs). In some examples, the UE 115 may be configured to use time hopping in the time domain or frequency hopping in the frequency domain to achieve diversity gain for the PUSCH. In some examples, PUSCH DMRS bundling may be supported for each hop (i.e., the DMRSs of the PUSCHs in the same hop may be bundled). Referring to Figure 10 Examples of frequency hopping are described, and referring to Figure 11 Examples without frequency hopping are described.

[0180] Figure 10 FIG. 1100 shows an example of a block diagram that supports PUSCH repetition using DMRS bundling according to aspects of the present disclosure. The block diagram 1000 may implement aspects of the wireless communication systems 100 and 200 described respectively with reference to Figure 1 and Figure 2 . The block diagram 1000 may implement aspects of the wireless communication systems 100 and 200 described respectively with reference to Figure 1 and Figure 2Aspects of the wireless communication systems 100 and 200 described. Block diagram 1000 may be based on the configuration of base station 105 or UE 115 and is implemented by UE 115.

[0181] In Figure 10 the example shown, block diagram 1000 is applicable to implementations or instances when UE 115 is configured with PUSCH DMRS bundling operations to support PUSCH repetition or PUSCH (retransmission) transmissions or both. For example, block diagram 1000 may include one or more PUSCH DMRS 1005 (which may be part of PUSCH DMRS bundle 1010), and one or more PUSCH DMRS 1015 (which may be part of PUSCH DMRS bundle 1020). PUSCH DMRS bundle 1010 and PUSCH DMRS bundle 1020 may correspond to time resources (e.g., symbol duration, mini-slot duration, slot duration, subframe duration, frame duration) and frequency resources (e.g., subcarrier, carrier). For example, each PUSCH DMRS 1005 or 1015 may span a mini-slot duration or a slot duration. In Figure 10 the example, PUSCH DMRS bundle 1010 may involve a first frequency hop, and PUSCH DMRS bundle 1020 may involve a second frequency hop different from the first frequency hop. Thus, UE 115 may be configured to use frequency hopping in the frequency domain to achieve diversity gain for PUSCH. In some examples, PUSCH DMRS bundling may be supported for each hop (i.e., the DMRS of PUSCH in the same hop may be bundled).

[0182] Figure 11 An example of block diagram 1100 is shown that supports PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure. Block diagram 1100 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. Block diagram 1100 may implement aspects of the wireless communication systems 100 and 200 described with reference to Figure 1 and Figure 2 respectively. Block diagram 1100 may be based on the configuration of base station 105 or UE 115 and is implemented by UE 115.

[0183] In Figure 11In the example shown, block diagram 1100 is applicable to an implementation or instance when the UE 115 is configured with PUSCH DMRS bundling operations to support PUSCH repetition or PUSCH (retransmission) transmission or both. For example, block diagram 1100 may include one or more PUSCH DMRS 1105 (which may be part of PUSCH DMRS bundle 1110), and one or more PUSCH DMRS 1115 (which may be part of PUSCH DMRS bundle 1120). PUSCH DMRS bundle 1110 and PUSCH DMRS bundle 1120 may correspond to time resources (e.g., symbol duration, mini-slot duration, slot duration, sub-frame duration, frame duration) and frequency resources (e.g., sub-carrier, carrier). For example, each PUSCH DMRS 1105 or 1115 may span a mini-slot duration or a slot duration. In Figure 11 the example of, there may be no frequency hopping between PUSCH DMRS bundle 1110 and PUSCH DMRS bundle 1120.

[0184] Return Figure 2 and refer to Figure 10 , in some examples, the number of symbols, mini-slots, or slots for PUSCH (e.g., PUSCH transmission) in a hop among multiple hops in the time domain or frequency domain may be the same as or different from that in another hop among the multiple hops. In some examples, if the number of symbols, mini-slots, or slots for PUSCH is different for each hop, the base station 105 may send an indication of the number of symbols, mini-slots, or slots for PUSCH in each hop to the UE 115. Otherwise, the number of symbols, mini-slots, or slots for PUSCH in each hop may be common to all hops. In some examples, the number of symbols, mini-slots, or slots for PUSCH DMRS coherent transmission in a hop among multiple hops in the time domain or frequency domain may be the same as or different from that in another hop among the multiple hops. In some examples, if the number of symbols, mini-slots, or slots for PUSCH DMRS coherent transmission is different for each hop, the base station 105 may send an indication of the number of symbols, mini-slots, or slots for PUSCH DMRS coherent transmission in each hop to the UE 115. Otherwise, the number of symbols, mini-slots, or slots for PUSCH DMRS coherent transmission in each hop may be common to all hops.

[0185] In some examples, the base station 105 may configure the UE 115 to support a constant transmission power for the PUSCH carrying the CSI report 205 (e.g., an aperiodic CSI report) for each of multiple hops, so that the UE 115 can maintain phase continuity for PUSCH transmissions. For example, the base station 105 may configure the UE 115 via a transmit power control (TPC) command to use a transmission power level for the PUSCH carrying the CSI report 205 (e.g., an aperiodic CSI report) for each of multiple hops. In some examples, the base station 105 may send a TPC command for each of multiple hops, so that the UE 115 can adjust the transmission power level of the PUSCH carrying the CSI report 205 (e.g., an aperiodic CSI report) for each of multiple hops. For example, the transmission power level for the PUSCH in the first hop may be different from the transmission power level for the PUSCH in the second hop.

[0186] In some examples, the base station 105 may determine a transmission power level difference between the first hop and the second hop and send an indication of the power level difference to the UE 115 via system information (SI) signaling or RRC signaling. The UE 115 may perform a ramp-up operation based on the indicated transmission power level difference, e.g., from the transmission power level of the first hop to the transmission power level of the second hop. Alternatively, the transmission power level difference between the first hop and the second hop may be pre-determined (e.g., fixed), and the UE 115 may be configured with a power level configuration that can indicate the power level difference. In some examples, the UE 115 may disable the ramp-up operation for cases with frequency hopping and enable the ramp-up operation for cases without frequency hopping.

[0187] For example, the operations performed by the base station 105 and the UE 115 may provide improvements to the PUSCH DMRS bundling operation related to PUSCH repetitions carrying aperiodic CSI reports in the wireless communication system 200. In addition, the operations performed by the base station 105 and the UE 115 may provide benefits and enhancements to the operation of the UE 115. For example, by supporting the PUSCH DMRS bundling operation related to PUSCH repetitions carrying aperiodic CSI reports, the UE 115 can conserve power while supporting higher reliability and lower latency communications, resulting in enhanced power efficiency and network throughput in the wireless communication system 200.

[0188] Figure 12Block diagram 1200 of device 1205 supporting PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure is shown. Device 1205 may be an example of aspects of UE 115 as described herein. Device 1205 may include a receiver 1210, a UE communication manager 1215, and a transmitter 1220. Device 1205 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0189] Receiver 1210 may receive information associated with various information channels (e.g., control channels, data channels, information related to PUSCH carrying an aperiodic CSI report, etc.), such as packets, user data, or control information. The information may be passed to other components of device 1205. Receiver 1210 may be an example of aspects of transceiver 1520 described herein. Receiver 1210 may utilize a single antenna or an antenna array. Figure 15 Receiver 1210 may utilize a single antenna or an antenna array.

[0190] UE communication manager 1215 may: receive signaling including CSI report configuration, determine one or more resources of a physical uplink channel for an aperiodic CSI report based on the CSI report configuration, and transmit the aperiodic CSI report via the physical uplink channel based on the one or more resources. UE communication manager 1215 may: determine a set of DMRS symbols associated with a jump in a set of jumps in the time domain or frequency domain; and coherently transmit the set of DMRS symbols associated with the jump in the set of jumps based on the determination. UE communication manager 1215 may be an example of aspects of UE communication manager 1510 described herein.

[0191] As described herein, UE communication manager 1215 may be implemented to achieve one or more potential advantages. One implementation may allow device 1205 to save power and increase battery life by communicating more efficiently with base station 105 (as shown). For example, device 1205 may extend the coverage of PUSCH for an aperiodic CSI report. Additionally, device 1205 may experience reduced complexity, better throughput through aperiodic CSI reporting or DMRS bundling or both. As a result of supporting PUSCH repetition configuration and PUSCH (retransmission) transmission configuration, another implementation may facilitate higher reliability and lower latency communication at device 1205 due to the flexibility of aperiodic CSI reporting at device 1205. Figure 2 As a result of supporting PUSCH repetition configuration and PUSCH (retransmission) transmission configuration, another implementation may facilitate higher reliability and lower latency communication at device 1205 due to the flexibility of aperiodic CSI reporting at device 1205.

[0192] The UE communication manager 1215 or its sub-components may be implemented in hardware, code executed by a processor (e.g., software or firmware), or any combination thereof.

[0193] The UE communication manager 1215 or its sub-components may be physically located in various positions, including being distributed such that portions of the functions are implemented by one or more physical components in different physical locations.

[0194] The transmitter 1220 may transmit signals generated by other components of the device 1205. In some examples, the transmitter 1220 may be co-located with the receiver 1210 in a transceiver component. For example, the transmitter 1220 may be an example of aspects of the transceiver 1520 described in Figure 15 reference. The transmitter 1220 may utilize a single antenna or an antenna array.

[0195] Figure 13 Block diagram 1300 of a device 1305 supporting PUSCH repetition using DMRS bundling in accordance with various aspects of the present disclosure is shown. The device 1305 may be an example of aspects of the device 1205 or the UE 115 described herein. The device 1305 may include a receiver 1310, a UE communication manager 1315, and a transmitter 1345. The device 1305 may also include a processor. Each of these components may communicate with one another (e.g., via one or more buses).

[0196] The receiver 1310 may receive information associated with various information channels (e.g., control channels, data channels, and information related to PUSCH carrying an aperiodic CSI report, etc.), such as packets, user data, or control information. The information may be passed to other components of the device 1305. The receiver 1310 may be an example of aspects of the transceiver 1520 described in Figure 15 reference. The receiver 1310 may utilize a single antenna or an antenna array.

[0197] The UE communication manager 1315 may be an example of aspects of the UE communication manager 1215 described herein. The UE communication manager 1315 may include a configuration component 1320, a channel component 1325, a reporting component 1330, a signal component 1335, and a group component 1340. The UE communication manager 1315 may be an example of aspects of the UE communication manager 1510 described herein.

[0198] The configuration component 1320 may receive signaling including CSI report configuration. The channel component 1325 may determine one or more resources of a physical uplink channel for an aperiodic CSI report based on the CSI report configuration. The reporting component 1330 may send an aperiodic CSI report via the physical uplink channel based on the one or more resources.

[0200] Figure 14 Block diagram 1400 illustrates a UE communication manager 1405 supporting PUSCH repetition using DMRS bundling in accordance with aspects of the present disclosure. The UE communication manager 1405 may be an example of aspects of the UE communication manager 1215, the UE communication manager 1315, or the UE communication manager 1510 described herein. The UE communication manager 1405 may include a configuration component 1410, a channel component 1415, a reporting component 1420, a payload component 1425, a carrier component 1430, a feedback component 1435, a signal component 1440, a group component 1445, and a power component 1450. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).

[0201] The configuration component 1410 may receive signaling including CSI report configuration. The CSI report configuration includes PUSCH repetition configuration. The configuration component 1410 may determine one or more resources of the PUSCH for the aperiodic CSI report by determining one or more resources of the physical uplink channel based on the PUSCH repetition configuration. In some examples, the configuration component 1410 may determine the PUSCH repetition based on the PUSCH repetition configuration, where transmitting the aperiodic CSI report includes transmitting the aperiodic CSI report via the physical uplink channel according to the PUSCH repetition. In some examples, the PUSCH repetition includes repetition of the physical uplink channel via one or more resources including mini-slots or slots. In some examples, the repetition of the physical uplink channel via one or more resources is continuous. In some examples, the repetition of the physical uplink channel via one or more resources is discontinuous.

[0202] The configuration component 1410 may determine to transmit the aperiodic CSI report on the physical uplink channel based on the CSI report configuration, where the physical uplink channel includes the PUSCH, and where transmitting the aperiodic CSI report includes transmitting the aperiodic CSI report on the PUSCH based on the determination. In some examples, the configuration component 1410 may determine that the PUSCH is configured to specifically carry the aperiodic CSI report. In some examples, the configuration component 1410 may determine that the PUSCH is configured to jointly carry the aperiodic CSI report and a transport channel, where the transport channel includes the UL-SCH. In some examples, the configuration component 1410 may jointly transmit the aperiodic CSI report and the UL-SCH on the PUSCH. In some cases, the CSI report configuration includes one or more of the PUSCH repetition configuration or the PUSCH (retransmission) transmission configuration. In some cases, the PUSCH repetition includes repetition of the physical uplink channel via one or more resources including mini-slots or slots. In some cases, the signaling includes RRC signaling. In some cases, the signaling includes downlink control signaling. In some cases, the signaling includes MAC-CE signaling.

[0203] The configuration component 1410 may receive signaling including an indication of a set of DMRS symbols associated with the jumps in the jump set, wherein the determination of the set of DMRS symbols is based on the indication. In some examples, the configuration component 1410 may receive signaling including an indication of a second set of DMRS symbols associated with a second jump in the jump set, wherein the determination of the second set of DMRS symbols is based on the indication. In some examples, the configuration component 1410 may receive signaling including an indication of a set of resources of one or more physical uplink channels associated with a second jump in the jump set, wherein the determination of the set of resources of one or more physical uplink channels associated with the second jump in the jump set is based on the indication, and the set of resources includes a set of symbols or a set of time slots. In some cases, the amount of resources of the set of resources of one or more physical uplink channels associated with the jumps in the jump set is different from the amount of resources of the set of resources of one or more physical uplink channels associated with the second jump in the jump set.

[0204] The channel component 1415 may determine one or more resources of a physical uplink channel for an aperiodic CSI report based on the CSI report configuration. In some examples, the channel component 1415 may determine one or more resources of a physical uplink channel based on the PUSCH repetition configuration. In some examples, the channel component 1415 may determine one or more resources of a physical uplink channel based on the PUSCH (retransmission) transmission configuration. In some examples, the channel component 1415 may determine a set of resources of one or more physical uplink channels associated with the jumps in the jump set in the time domain or the frequency domain. In some examples, the channel component 1415 may receive signaling including an indication of a set of resources of one or more physical uplink channels associated with the jumps in the jump set, wherein the determination of the set of resources of one or more physical uplink channels associated with the jumps in the jump set is based on the indication, and the set of resources includes a set of symbols or a set of time slots.

[0205] In some examples, the channel component 1415 may determine a set of resources of one or more physical uplink channels associated with a second jump in the jump set in the time domain or the frequency domain. In some cases, one or more resources of the physical uplink channel include one or more mini-slots. In some cases, one or more resources of the physical uplink channel include one or more time slots.

[0206] The reporting component 1420 may send an aperiodic CSI report via a physical uplink channel based on one or more resources. In some examples, the reporting component 1420 may specifically send an aperiodic CSI report on the PUSCH. In some examples, when the physical uplink channel is scheduled to carry an aperiodic CSI report and a transport channel, the reporting component 1420 may identify that the UE is not configured with PUSCH repetition or PUSCH (retransmission) transmission, or neither, where the transport channel includes the UL-SCH. In some examples, the reporting component 1420 may avoid sending the transport channel on the PUSCH based on the identification.

[0207] The signal component 1440 may determine a set of DMRS symbols associated with a jump in a set of jumps in the time domain or the frequency domain. In some examples, the signal component 1440 may determine a second set of DMRS symbols associated with a second jump in the set of jumps in the time domain or the frequency domain. In some cases, the amount of DMRS of the DMRS set associated with the jumps in the set of jumps is different from the amount of DMRS of the second DMRS set associated with the second jump in the set of jumps.
