Patent Description:
<NUM> NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new specifications associated with latency, reliability, security, scalability (such as with Internet of Things (IoT)), and other specifications.

<CIT> relates to techniques and apparatus for enhancing uplink grant-free transmissions and/or downlink semi-persistent scheduling (SPS) transmissions, e.g., for ultra reliable low latency communications.

<CIT> relates to decoupled transmissions of channel quality feedback and acknowledgement/negative-acknowledgement feedback.

<CIT> relates to handling enhanced Mobile Broadband and Ultra Reliable Low Latency Communication simultaneous transmissions.

In some <NUM> NR communication systems, a user equipment (UE) may provide channel state information (CSI) reports in physical uplink shared channel (PUSCH). In order to receive more up-to-date CSI, a base station may trigger a UE's CSI reporting with a downlink (DL) grant. The UE may be triggered to provide a CSI report by transmitting in physical uplink control channel (PUCCH). However, for semi-persistent scheduling (SPS) transmissions, there may be no DL grant and the base station may not be able to trigger a UE's CSI reporting with a DL grant.

In the following, each of the described methods, apparatuses, examples, and aspects which do not fully correspond to the invention as defined in the claims is thus not according to the invention and is, as well as the whole following description, present for illustration purposes only or to highlight specific aspects or features of the claims.

However, it will be apparent to a person of ordinary skill in the art that these concepts may be practiced without these specific details. In some instances, structures and components are shown in block diagram form in order to avoid obscuring such concepts.

Software is to be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

Accordingly, in one or more examples, the functions described may be implemented in hardware, software, or any combination thereof. By way of example, and not limitation, such computer-readable media can include a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

While aspects and implementations are described in this application by illustration to some examples, a person of ordinary skill in the art will understand that additional implementations and use cases may come about in many different arrangements and scenarios. Aspects described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, implementations or uses may come about via integrated chip implementations and other non-module-component based devices (such as end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail/purchasing devices, medical devices, artificial intelligence (AI)-enabled devices, or the like). While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described innovations may occur. Implementations may range a spectrum from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating described aspects and features may also include additional components and features for implementation and practice of claimed and described aspect. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes (such as hardware components including antenna, RF-chains, power amplifiers, modulators, buffer, processor(s), interleaver, adders/summers, or the like). It is intended that innovations described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. of varying sizes, shapes, and constitution.

A base station may transmit a downlink grant to a user equipment (UE) in order to indicate to the UE to provide a channel state information (CSI) report to the base station. In some examples, the base station may transmit a wireless communication, such as a semi-persistent scheduling (SPS) communication, without a downlink grant for each physical downlink shared channel (PDSCH) occasion However, for SPS transmissions, there may be no DL grant and the base station may not be able to trigger a UE' s CSI reporting with a DL grant.

Aspects presented herein enable a base station to trigger hybrid automatic repeat request (HARQ) feedback with CSI for downlink SPS transmissions. In some aspects, a UE may receive, from the base station, triggering information for transmitting a CSI report associated with a DL SPS transmission in a PDSCH and may transmit the CSI report based on the received trigger. The triggering information may be a defined demodulation reference signal (DM-RS) or downlink control information (DCI). For example, a defined DM-RS sequence, a DCI, or a defined field within the DCI may trigger a UE to transmit a CSI report. If the UE receives the triggering information from the base station, the UE may transmit the HARQ feedback for the downlink SPS transmission along with the CSI report. If the UE does not receive the triggering information from the base station, the UE may transmit the HARQ feedback for the downlink SPS transmission without a CSI report.

Particular implementations of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some aspects, the disclosed techniques enable a base station to trigger the UE to provide more up-to-date CSI information for SPS transmissions while also conserving network resources by not transmitting a DL grant. With more up-to-date CSI information, the base station may change configurations and select transmission parameters that are better-suited for the current channel, which may in turn improve physical uplink shared channel (PUSCH) communications and overall communication quality between the UE and the base station.

The wireless communications system (also referred to as a wireless wide area network (WWAN)) includes base stations <NUM>, UEs <NUM>, an Evolved Packet Core (EPC) <NUM>, and another core network <NUM> (such as a <NUM> Core (5GC)). The base stations <NUM> may include macrocells (high power cellular base station) or small cells (low power cellular base station).

The base stations <NUM> configured for <NUM> LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC <NUM> through first backhaul links <NUM> (such as a S1 interface). The base stations <NUM> configured for <NUM> NR(collectively referred to as Next Generation RAN (NG-RAN)) may interface with core network <NUM> through second backhaul links <NUM>. In addition to other functions, the base stations <NUM> may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (such as handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations <NUM> may communicate directly or indirectly (such as through the EPC <NUM> or core network <NUM>) with each other over third backhaul links <NUM> (such as an X2 interface).

The communication links <NUM> between the base stations <NUM> and the UEs <NUM> may include uplink (UL) (also referred to as reverse link) transmissions from a UE <NUM> to a base station <NUM> or downlink (DL) (also referred to as forward link) transmissions from a base station <NUM> to a UE <NUM>. The communication links <NUM> may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, or transmit diversity. The base stations <NUM> / UEs <NUM> may use spectrum up to YMHz (such as <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. Allocation of carriers may be asymmetric with respect to DL and UL (such as more or fewer carriers may be allocated for DL than for UL).

Some UEs <NUM> may communicate with each other using device-to-device (D2D) communication link <NUM>.

The wireless communications system may further include a Wi-Fi access point (AP) <NUM> in communication with Wi-Fi stations (STAs) <NUM> via communication links <NUM>, such as in a <NUM> unlicensed frequency spectrum or the like.

The small cell <NUM>' may operate in a licensed or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell <NUM>' may employ NR and use the same unlicensed frequency spectrum (such as <NUM>, or the like) as used by the Wi-Fi AP <NUM>. The small cell <NUM>', employing NR in an unlicensed frequency spectrum, may boost coverage to or increase capacity of the access network.

Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into mid-band frequencies. Higher frequency bands may also be explored to extend <NUM> NR operation beyond <NUM>. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-<NUM> (<NUM> - <NUM>), FR4 (<NUM> - <NUM>), and FR5 (<NUM> -<NUM>).

With the above aspects in mind, unless specifically stated otherwise, the term "sub-<NUM>" or the like if used herein may broadly represent frequencies that may be less than <NUM>, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, the term "millimeter wave" or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-<NUM>, or FR5, or may be within the EHF band.

A base station <NUM>, whether a small cell <NUM>' or a large cell (for example a macro base station), may include or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations, such as gNB <NUM> may operate in a traditional sub <NUM> spectrum, in millimeter wave frequencies, or near millimeter wave frequencies in communication with the UE <NUM>. The base station <NUM> and the UE <NUM> may each include a plurality of antennas, such as antenna elements, antenna panels, or antenna arrays to facilitate the beamforming.

The IP Services <NUM> may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, or other IP services.

The IP Services <NUM> may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switch (PS) Streaming (PSS) Service, or other IP services.

The base station may include or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. Examples of UEs <NUM> include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (such as a MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs <NUM> may be referred to as IoT devices (such as a parking meter, gas pump, toaster, vehicles, heart monitor, etc.).

Referring again to <FIG>, the UE <NUM> includes an CSI report component <NUM>. The CSI report component <NUM> may be configured to receive triggering information associated with transmitting one or more CSI reports associated with one or more DL SPS transmissions in one or more PDSCH occasions. The CSI report component <NUM> may be configured to receive a first DL SPS transmission of the one or more DL SPS transmissions in a first PDSCH occasion of the one or more PDSCH occasions and transmit a first CSI report associated with the first DL SPS transmission based on receiving the triggering information. The base station <NUM>/<NUM> includes an CSI report trigger component <NUM>. The CSI report trigger component <NUM> may be configured to transmit, to a UE, triggering information associated with one or more CSI reports associated with one or more DL SPS transmissions in one or more PDSCH occasions including a first PDSCH occasion. The CSI report trigger component <NUM> may be configured to receive, from the UE based on the triggering information, a first CSI report in a physical uplink control channel (PUCCH).

In the examples provided by Figure s 2A, 2C, the <NUM> NR frame structure is assumed to be TDD, with subframe <NUM> being configured with slot format <NUM> (with mostly DL), where D is DL, U is UL, and F is flexible for use between DL/UL, and subframe <NUM> being configured with slot format <NUM> (with all UL). Note that the description provided herein applies also to a <NUM> NR frame structure that is TDD.

Other wireless communication technologies may have a different frame structure or different channels. For slot configuration <NUM>, different numerologies µ <NUM> to <NUM> allow for <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> slots, respectively, per subframe. <FIG> provide an example of slot configuration <NUM> with <NUM> symbols per slot and numerology µ=<NUM> with <NUM> slots per subframe. The slot duration is <NUM>, the subcarrier spacing is <NUM>, and the symbol duration is approximately <NUM>. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see <FIG>) that are frequency division multiplexed. Each BWP may have a particular numerology.

The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (for example, <NUM>, <NUM>, <NUM>, <NUM>, or <NUM> CCEs), each CCE including six RE groups (REGs), each REG including <NUM> consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET). A UE is configured to monitor PDCCH candidates in a PDCCH search space (for example common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater or lower frequencies across the channel bandwidth. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block (also referred to as SS block (SSB)). The PDSCH carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages.

The UE may transmit DM-RS for the PUCCH and DM-RS for the physical uplink shared channel (PUSCH).

The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) or negative ACK (NACK) feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), or UCI.

The controller/processor <NUM> provides RRC layer functionality associated with broadcasting of system information (for example a MIB, SIBs), RRC connection control (for example RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

The TX processor <NUM> handles mapping to signal constellations based on various modulation schemes (for example, binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (such as a pilot) in the time or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The channel estimate may be derived from a reference signal or channel condition feedback transmitted by the UE <NUM>. Each spatial stream may then be provided to a different antenna <NUM> via a separate transmitter <NUM> TX. Each transmitter <NUM> TX may modulate an RF carrier with a respective spatial stream for transmission.

At the UE <NUM>, each receiver <NUM> RX receives a signal through its respective antenna <NUM>. Each receiver <NUM> RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor <NUM>. The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal.

The controller/processor <NUM> is also responsible for error detection using an ACK or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DL transmission by the base station <NUM>, the controller/processor <NUM> provides RRC layer functionality associated with system information (such as MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

The controller/processor <NUM> is also responsible for error detection using an ACK or NACK protocol to support HARQ operations.

At least one of the TX processor <NUM>, the RX processor <NUM>, and the controller/processor <NUM> may be configured to perform aspects in connection with CSI report trigger component <NUM> of <FIG>.

At least one of the TX processor <NUM>, the RX processor <NUM>, and the controller/processor <NUM> may be configured to perform aspects in connection with CSI report component <NUM> of <FIG>.

In some wireless communication systems, a base station may schedule a UE to transmit an CSI report on a PUSCH using an UL grant. The base station may also use a DL grant to trigger a CSI report on a PUCCH. The CSI report on the PUCCH may enable faster CSI reporting than CSI reporting on the PUSCH, such as to provide the base station with more up-to-date CSI information, which in turn may improve PUSCH performance, such as through a reduced latency or increased reliability. <FIG> and <FIG> illustrate examples of CSI triggered by a DL grant on a PUCCH in accordance with various aspects of the present disclosure. As illustrated in in example <NUM> in <FIG>, a base station may transmit a DL grant <NUM> associated with a PDSCH <NUM> to a UE. In response to receiving the DL grant <NUM> associated with the PDSCH <NUM>, the UE may transmit a HARQ feedback message (such as a HARQ-ACK) in a PUCCH resource <NUM>. Alternatively, as illustrated in example <NUM> in <FIG>, a base station may transmit a DL grant <NUM> associated with a PDSCH <NUM> to a UE. In response to receiving the DL grant <NUM>, the UE may transmit a HARQ feedback message (such as a HARQ-ACK) and CSI in a same PUCCH resource <NUM>. The HARQ feedback message and the associated CSI transmitted in the same PUCCH resource <NUM> may be referred as a "soft HARQ feedback message".

For DL SPS (which may be otherwise referred as grant-free scheduling), there may be no DL grant. Because there may be no DL grant, the base station may not use a DL grant to trigger a CSI report with HARQ feedback. Mechanisms for triggering CSI report with HARQ feedback for DL SPS are provided herein. In some aspects, a UE may receive a trigger to transmit CSI report associated with DL SPS transmission in PDSCH and may transmit the CSI report based on the received trigger. The trigger may be a DM-RS or a DCI. By utilizing such mechanisms for DL SPS, more up-to-date CSI information may be provided to a base station which may in turn improve PUSCH and overall communication quality between the UE and the base station.

As illustrated in in example <NUM> in <FIG>, a base station may periodically transmit DL SPS transmissions 602A, 602B, 602C, 602D,. , 602N, and 602O to a UE. The periodicity of the DL SPS transmission may be transmitted to and configured for the UE in RRC transmissions. The base station may transmit a DCI to trigger CSI reporting for the UE. In some aspects, the DCI itself may be the trigger. In some aspects, the DCI may include the trigger. For example, after a UE receives a DCI 604A that triggers CSI report with a HARQ feedback message (which may be referred to as soft HARQ feedback message), the UE may transmit a CSI report for a next DL SPS transmission 602B on a PUCCH resource 606B. Similarly, after a UE receives a DCI 604D that triggers CSI report with a HARQ feedback message (for example, a soft HARQ feedback message), the UE may transmit a CSI report for a next DL SPS transmission 602N on a PUCCH resource 606N. Without the DCI that triggers CSI reporting, the UE may transmit a HARQ feedback message without a CSI report upon receiving the DL SPS transmissions 602A, 602C, 602D, and 602O in PUCCH resources 606A, 606C, 606D, and 606O. The CSI report may include a channel quality information (CQI), a modulation and coding scheme (MCS), a block error ratio (BLER), a bit error rate (BER), or a next best redundancy version (RV), a channel rank, or an average received power. In some aspects, the CSI report may be generated based on one or more of a DM-RS or aPDSCH. In some aspects, the trigger may trigger CSI report regardless of whether HARQ feedback message would be transmitted.

In some aspects, the trigger may be a DM-RS instead of a DCI. As illustrated in in example <NUM> in <FIG>, a base station may periodically transmit DL SPS transmissions 702A, 702B, 702C, 702D,. , 702N, and 702O to a UE. The base station may transmit a trigger DM-RS to trigger CSI reporting for the UE. In some aspects, the trigger DM-RS may be a DM-RS of a different sequence compared to other nominal DM-RS, such as an even or odd element sign flipped DMRS that flips sign of even or odd numbered elements. The base station may include the trigger-DMRS in DL SPS transmission to trigger CSI reporting for the UE. For example, after a UE receives a trigger DM-RS that triggers CSI report with a HARQ feedback message (for example, soft HARQ feedback message) in the DL SPS transmission 602B, the UE may transmit a CSI report on a PUCCH resource 706B associated with the DL SPS transmission 702B. Similarly, after a UE receives a trigger DM-RS that triggers CSI report with a HARQ feedback message (for example, soft HARQ feedback message) in the DL SPS transmission 702N, the UE may transmit a CSI report on a PUCCH resource 706N associated with the DL SPS transmission 702B. Without the trigger DM-RS that triggers CSI reporting, the UE may transmit a HARQ feedback message without a CSI report upon receiving the DL SPS transmissions 702A, 702C, 702D, and 702O in PUCCH resources 706A, 706C, 706D, and 706O. The DL SPS transmissions 702A, 702C, 702D, and 702O may each include a DM-RS that is not the trigger DM-RS.

In some aspects, the trigger may trigger CSI reporting for the UE for one DL SPS transmissions as illustrated in example <NUM> and <NUM>. In some aspects, the trigger may trigger CSI reporting for the UE for a configured number of DL SPS transmissions. As illustrated in in example <NUM> in <FIG>, a base station may periodically transmit DL SPS transmissions 802A, 802B, 802C, 802D,. , 802N, and 802O to a UE. The base station may transmit a DCI to trigger CSI reporting for a configured number (for example, <NUM>) of DL SPS transmissions for the UE. The configured number may be configured via radio resource control (RRC) signaling, a medium access control (MAC) control element (MAC-CE), or DCI.

After a UE receives a DCI 804A that triggers CSI report, the UE may transmit CSI reports for next two DL SPS transmissions 802B and 802C on PUCCH resources 806B and 806C. Similarly, after a UE receives a DCI 804D that triggers CSI report with a HARQ feedback message (for example, soft HARQ feedback message), the UE may transmit a CSI report for next two DL SPS transmissions 802N and 802O on PUCCH resources 806N and 806O. Without the DCI that triggers CSI reporting, the UE may transmit a HARQ feedback message without a CSI report upon receiving the DL SPS transmissions 802A, 802D, and 802O in PUCCH resources 806A, 806D, and 806O. In some aspects, the trigger may trigger CSI reporting without a HARQ feedback message. For example, the scheduled DL SPS transmission 802O may be an empty DL SPS transmission where the base station decided to not transmit data in the DL SPS transmission 802O. Because the UE received trigger DCI 804D that triggers CSI reporting for DL SPS transmission 802O, the UE may transmit a CSI report on PUCCH 806O without transmitting HARQ feedback message on PUCCH 806O.

<FIG> illustrates an example communication flow <NUM> between a base station <NUM> and a UE <NUM>. As illustrated in <FIG>, the UE <NUM> and the base station <NUM> may establish RRC connection <NUM>. The base station <NUM> may configure the UE <NUM> with a periodicity of DL SPS transmission via RRC connection <NUM>. After the RRC connection <NUM>, the base station <NUM> may start periodically transmitting DL SPS transmissions 910A, 910B, or the like, in accordance with a configured periodicity <NUM> to the UE <NUM>. After detecting a trigger DCI <NUM> associated with the DL SPS transmission 910A or detecting a trigger DM-RS included in the DL SPS transmission 910A, the UE <NUM> may generate a CSI report and transmit a HARQ feedback message with the CSI report on PUCCH914A. In some aspects, the DL SPS transmission 910B may not be associated with a trigger (for example, a DCI or a trigger DM-RS). The UE <NUM> may transmit a HARQ feedback message 914B without a CSI report on a PUCCH upon receiving the DL SPS transmission 910B. In some aspects, the trigger DCI <NUM> may trigger the soft report (the HARQ feedback message with the CSI report on PUCCH 914A) if the trigger DCI <NUM> is received Z symbols, slots, or mini-slots before the PUCCH resource (PUCCH 914A) scheduled to send HARQ-ACK/CSI feedback of the PDSCH occasion in the DL SPS transmission 910A. Z may be an positive integer.

<FIG> is a flowchart <NUM> of a method of wireless communication at a UE that supports DCI or DM-RS triggered CSI reporting in accordance with various aspects of the present disclosure. The method may be performed by a UE such as the UE <NUM>, the UE <NUM>, the apparatus <NUM>, or the like.

At <NUM>, the UE receives triggering information associated with transmitting one or more CSI reports associated with one or more DL SPS transmissions in PDSCH occasions from a base station. In some aspects, the reception at <NUM> may be performed by triggering component <NUM> of <FIG>. In some aspects, the triggering information may correspond to the DCI 604A/604D in <FIG>, the DM-RS in DL SPS 702B/702N in <FIG>, the DCI 804A/804D in <FIG>, the trigger DCI <NUM> or the DM-RS in the DL SPS 910A in <FIG>, or the like. In some aspects, the one or more DL SPS transmissions to DL SPS transmission 602B/602N in <FIG>, the DL SPS transmission 702B/702N in <FIG>, the DL SPS 802B/802C/802N/802O in <FIG>, the DL SPS transmission 910A, or the like. In some aspects, the first PDSCH occasion may correspond to the DL SPS transmission 602B/602N in <FIG>, the DL SPS transmission 702B/702N in <FIG>, the DL SPS transmission 802B/802N in <FIG>, the DL SPS transmission 910A, or the like. In some aspects, the UE may receive a second DL SPS transmission in a second PDSCH occasion that is not associated with the triggering information. For example, the second DL SPS transmission may correspond to the DL SPS transmission 602A/602C/602D/<NUM> in <FIG>, the DL SPS transmission 702A/702C/702D/702O in <FIG>, the DL SPS transmission 802A/802D in <FIG>, the DL SPS transmission 910B in <FIG>, or the like.

According to the present invention, the first PDSCH occasion includes a first DM-RS and receiving the triggering information includes receiving the first DM-RS. The first DM-RS triggers the UE to transmit the CSI report. For example, the DL SPS transmission 702B and 702N in <FIG> may correspond to the first PDSCH occasion that includes the DM-RS. In some aspects, the first DM-RS is a first type of DM-RS and the second PDSCH occasion includes a second DM-RS that is a second type of DM-RS different than the first type of DM-RS. For example, the trigger DM-RS in the DL SPS transmission 702B and 702N in <FIG> may correspond to the first DM-RS and the DM-RS in the DL SPS transmission 702A may correspond to the second DM-RS. In some aspects, the first type of DM-RS corresponds to a first DM-RS sequence and the second type of DM-RS corresponds to a second DM-RS sequence different than the first DM-RS sequence. In some aspects, each of the even-numbered elements in the first DM-RS sequence has an opposite sign relative to the respective even-numbered element in the second DM-RS sequence or each of the odd-numbered elements in the first DM-RS sequence has an opposite sign relative to the respective odd-numbered element in the second DM-RS sequence. In some aspects, the first type of DM-RS corresponds to a first DM-RS sequence and the second type of DM-RS corresponds to a second DM-RS sequence, the first DM-RS sequence being different from the second DM-RS sequence. In some aspects, the first type of DM-RS may correspond to a first DM-RS pattern or a first DM-RS configuration and the second type of DM-RS corresponds to a second DM-RS pattern or a second DM-RS configuration. The first DM-RS pattern or the first DM-RS configuration may be different from the second DM-RS pattern or the second DM-RS configuration. The first DM-RS configuration and the second DM-RS configuration may correspond to at least one of a DM-RS location, a DM-RS allocation in time or frequency resources, a DM-RS scrambling ID, or a number of DM-RS symbols.

In some aspects, the first PDSCH occasion is associated with a DCI. Receiving the triggering information may include receiving the DCI. The DCI may be triggering the UE to transmit the first CSI report or includes the trigger. For example, the first PDSCH occasion may correspond to the DL SPS transmission 602B/602N in <FIG> and the DCI may correspond to the DCI 604A/604D in <FIG>. In some aspects, the triggering information activates the UE to transmit the first CSI report for one PDSCH occasion after the received PDSCH.
