Description

[Technical Field]

[0001] Aspects of the present disclosure generally relate to techniques and apparatus associated with wireless communications and feedback corresponding to a unified transmission configuration indication in downlink control information without a downlink assignment. [Background technology]

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless network may include several base stations (BSs) that can support communication for several user equipments (UEs). The UEs may communicate with the BSs via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit / receive point (TRP), a new radio (NR) BS, a 5G Node B, etc.

[0004]

[0004] The above multiple access technologies have been adopted in various telecommunications standards to provide common protocols that enable different user equipment to communicate on a city, national, regional, or even global scale. NR, sometimes referred to as 5G, is a set of extensions to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectral efficiency, lower costs, improve service, utilize new spectrum, and better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), better integrating with other open standards, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0018]

[0022] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure encompasses any aspect of the present disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects described herein. Additionally, the scope of the present disclosure is intended to cover such apparatuses or methods practiced using other structure, functions, or structure and functions in addition to or other than the various aspects of the present disclosure described herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0019]

[0023] Several aspects of telecommunications systems are now presented with reference to various apparatus and techniques. These apparatus and techniques are described in the detailed description that follows and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0020]

[0024] It should be noted that although aspects may be described herein using terminology typically associated with 5G or NR radio access technologies (RATs), aspects of the present disclosure may apply to other RATs, such as 3G RATs, 4G RATs, and / or RATs subsequent to 5G (e.g., 6G).

[0021]

[0025] FIG. 1 illustrates an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include several base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit / receive point (TRP), etc. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to the coverage area of ​​a BS and / or the BS subsystem serving this coverage area, depending on the context in which the term is used.

[0022]

[0026] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs that have an association with the femto cell (e.g., a UE in a Closed Subscriber Group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in FIG. 1, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0023]

[0027] In some aspects, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0024]

[0028] Wireless network 100 may also include relay stations. A relay station is an entity that can receive a data transmission from an upstream station (e.g., a BS or a UE) and send the data transmission to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, etc.

[0025]

[0029] Wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference within wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5-40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1-2 watts).

[0026]

[0030] Network controller 130 may couple to a set of BSs and provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, e.g., directly or indirectly via a wireless or wired backhaul.

[0027]

[0031] The UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a mobile phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium.

[0028]

[0032] Some UEs may be considered machine type communication (MTC) or evolved or extended machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and / or a location tag that may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). The UE 120 may be included in a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0029]

[0033] Generally, any number of wireless networks may be deployed within a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, etc. A frequency may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT within a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0030]

[0034] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary for communicating with each other). For example, the UEs 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, a vehicle-to-everything (V2X) protocol (which may include, e.g., a vehicle-to-vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), and / or a mesh network. In this case, the UEs 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0031]

[0035] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which may be subdivided into various classes, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) that may extend from 410 MHz to 7.125 GHz and / or a second frequency range (FR2) that may extend from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the “sub-6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunications Union (ITU). Thus, unless otherwise specified, it should be understood that terms such as "sub-6 GHz," when used herein, can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that terms such as "millimeter wave," when used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). The frequencies included in FR1 and FR2 may be modified, and the techniques described herein are believed to be applicable to those modified frequency ranges.

[0032]

[0036] As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1.

[0033]

[0037] 2 is a diagram illustrating an example base station 110 200 communicating with a UE 120 in a wireless network 100 in accordance with the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0034]

[0038] At the base station 110, the transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0035]

[0039] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term “controller / processor” may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0036]

[0040] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0037]

[0041] Antennas (e.g., antennas 234a-234t and / or antennas 252a-252r) may include or be included in one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include a set of coplanar antenna elements and / or a set of non-coplanar antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components of FIG. 2.

[0038]

[0042] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a-254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to FIGS.

[0039]

[0043] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by a demodulator 232, detected by a MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communication. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230.

For example, functionality described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0056]

[0060] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0057]

[0061] Wireless communication devices, such as UEs and base stations, may use beams to facilitate communication with each other. A “beam” may refer to a directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicative of one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0058]

[0062] Antenna elements and / or subelements may be used to generate beams. For example, antenna elements may be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming involves the generation of a beam using multiple signals on different antenna elements, where one, more, or all of the multiple signals are phase-shifted relative to each other. The formed beam may carry a physical or higher-layer reference signal or information. As each signal of the multiple signals radiates from its respective antenna element, the radiated signals interact with each other, interfere (constructively or destructively), and amplify, resulting in the generation of a beam. The shape (such as amplitude, width, and / or presence of sidelobes) and direction (such as the angle of the beam relative to the surface of the antenna array) may be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.

[0059]

[0063] In 5G and other types of RATs, beamforming may be used for communications between a UE and a base station, such as for millimeter wave communications. In such cases, the base station may provide the UE with a configuration of transmission configuration indicator (TCI) states, each indicating a beam that may be used by the UE, such as for receiving a PDSCH. The base station may indicate the activated TCI states to the UE, which the UE may use to select a beam for receiving the PDSCH.

[0060]

[0064] A beam indication is an indication of a beam. The beam indication may be or include, among other examples, a TCI state information element, a beam identifier (ID), spatial relationship information, a TCI state ID, a closed-loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID. The TCI state information element (referred to herein as a TCI state) may indicate information associated with a beam, such as a downlink beam. For example, the TCI state information element may indicate a TCI state identification (e.g., tci-StateID), a quasi-co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), a cell identification (e.g., ServCellIndex), a bandwidth part identification (bwp-Id), a reference signal identification such as a CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.

[0061]

[0065] The beam indication may be a joint or separate downlink (DL) / uplink (UL) beam indication within the integrated TCI framework. In some cases, the network may support Layer 1 (L1)-based beam indication using at least a UE-specific (unicast) DCI to indicate joint or separate DL / UL beam indication from the active TCI state. In some cases, existing DCI formats 1_0, 1_1, 1_2, 0_1, 0_2, 0_0, and / or 2_x may be reused for beam indication. For example, a DCI transmission may include a beam indication having one of six types of beam indication for integrated TCI. Type 1 may include a joint DL / UL common TCI state to indicate a common beam for at least one DL channel and / or reference signal plus at least one UL channel and / or reference signal. Type 2 may include a separate DL common TCI state to indicate a common beam for two or more DL channels and / or reference signals. Type 3 may include an individual UL common TCI state to indicate a common beam for two or more UL channels and / or reference signals. Type 4 may include an individual DL single channel / reference signal TCI state to indicate a beam for a single DL channel and / or reference signal. Type 5 may include an individual UL single channel / reference signal TCI state to indicate a beam for a single UL channel and / or reference signal. Type 6 may include UL spatial relationship information (e.g., an SRS resource indicator (SRI)) to indicate a beam for a single UL channel and / or reference signal. The source reference signals in the aggregated TCI may provide quasi-co-location (QCL) information for at least one of PDSCH reception and PDCCH reception in at least the serving cell, and the source reference signals in the aggregated TCI may provide a reference for determining a common spatial transmit filter for at least one of SRS transmission, PUSCH transmission, and PUCCH transmission in the serving cell, if applicable.

[0062]

[0066] The network may include a support mechanism for the UE to acknowledge successful decoding of a beam indication (e.g., TCI) by using an acknowledgement / negative acknowledgement (ACK / NACK) of a PDSCH scheduled by a DCI carrying the beam indication as an ACK for the beam indication. However, in some cases, a DCI transmission may be used to indicate a TCI status without including a downlink assignment. For example, a DCI transmission having one of the formats listed above may be used to indicate a TCI status but may not include any scheduling information for downlink data. Therefore, an ACK / NACK for a PDSCH may not be available to be used for feedback for the beam indication. As a result, a beam indication in a DCI transmission without a downlink assignment may lead to unnecessary retransmissions due to the lack of feedback, which may increase network overhead and reduce network efficiency, thereby adversely affecting network performance.

[0063]

[0067] Some aspects of the techniques and apparatus described herein may facilitate providing feedback corresponding to a consolidated TCI indication in a DCI transmission that has no downlink assignment. For example, in some aspects, a UE may receive a DCI transmission indicating a consolidated TCI in a first slot, where the DCI transmission does not include a downlink assignment. The UE may transmit HARQ feedback corresponding to and responsive to the consolidated TCI indication in the DCI. The HARQ feedback may include an ACK (as confirmation) indicating successful reception of the consolidated TCI in the DCI transmission or a NACK indicating unsuccessful reception of the consolidated TCI in the DCI transmission. The UE may transmit the HARQ feedback in a second slot determined at least in part based on a value of a slot parameter. In this manner, some aspects may facilitate avoidance of unnecessary retransmissions due to lack of feedback, which may reduce network overhead and improve network efficiency, thereby positively impacting network performance.

[0064]

[0068] 3 is a diagram illustrating an example 300 relating to feedback corresponding to aggregated TCI in a DCI without a downlink assignment, in accordance with the present disclosure. As shown, a UE 305 and a base station 310 can communicate with each other.

[0065]

[0069] As indicated by reference numeral 315, the base station 310 may transmit, and the UE 305 may receive, an RRC message. The RRC message may indicate one or more parameters that may be used by the UE 305 to determine a slot, a PUCCH resource, and / or an ACK / NACK position within a HARQ codebook for transmitting HARQ feedback associated with and responsive to an integrated TCI indication within a DCI transmission that does not include a downlink assignment. For example, in some aspects, the RRC message may indicate a value of a slot parameter that may be used to determine a slot for transmitting HARQ feedback. In some aspects, the RRC message may include information from which the UE 305 may determine a PUCCH resource for transmitting HARQ feedback. For example, in some aspects, the RRC message may indicate a PUCCH resource index configured by a parameter such as TCI-PUCCH. In some aspects, the RRC message may indicate an ACK / NACK position within a static HARQ-ACK codebook for HARQ feedback (e.g., the first bit or the last bit in the HARQ-ACK codebook). In some aspects, a given PDSCH opportunity may be associated with an ACK / NACK position in a static HARQ-ACK codebook for HARQ feedback, and the RRC message may indicate the associated PDSCH opportunity.

[0066]

[0070] As indicated by reference numeral 320, the base station 310 may transmit, and the UE 305 may receive, a DCI transmission indicating the aggregated TCI. The DCI transmission may not include a downlink assignment. In some aspects, the DCI transmission may be verified as a DCI transmission with a TCI indication that does not include any downlink assignment based at least in part on a configured scheduling radio network temporary identifier (CS-RNTI), which may be used to scramble a cyclic redundancy check (CRC) for the DCI transmission. The DCI transmission may be verified as a DCI transmission with a TCI indication that does not include any downlink assignment based further at least in part on certain values ​​in certain fields. For example, the values ​​of the following DCI fields for a DCI transmission with a TCI indication that does not include any downlink assignment may be set as follows: all ones in the redundancy version field, all ones in the modulation and coding scheme field, zeros in the new data indicator, all zeros in the frequency domain resource allocation (FDRA) field if FDRA is configured as Type 0, all ones in the FDRA field if FDRA is configured as Type 1, and / or all zeros in the FDRA field if FDRA is configured as dynamicSwitch, among other examples. In some aspects, the DCI transmission may have DCI Format 1_0, DCI Format 1_1, DCI Format 1_2, DCI Format 0_1, DCI Format 0_2, DCI Format 0_0, or DCI Format 2_x.

[0067]

[0071] As indicated by reference numeral 325, the UE 305 may determine one or more resources to be used for transmitting HARQ feedback corresponding to the aggregated TCI in the DCI that does not include any downlink assignment. Based at least in part on the determined resources, the UE 305 may transmit, and the base station 310 may receive, the HARQ feedback, as indicated by reference numeral 330. The HARQ feedback may include an ACK indicating successful reception of the DCI transmission or a NACK indicating unsuccessful reception of the DCI transmission.

[0068]

[0072] In some aspects, for example, the UE 305 may transmit HARQ feedback corresponding to or responsive to the aggregated TCI in the DCI that does not include any downlink assignment using a PUCCH transmission in a second slot apart from the first slot n, and the UE 305 receives the DCI over a number of slots indicated by the value k of the slot parameter. That is, the second slot may be determined by n+k. The DCI format of the DCI transmission may include a PDSCH-to-HARQ feedback timing indicator field indicating the value k of the slot parameter (e.g., to indicate slot offset k1). The DCI format of the DCI transmission may include a PDSCH-to-HARQ feedback timing indicator field indicating the slot offset k1 and a time-domain resource allocation field indicating the value of parameter k0. The sum of the values ​​of the time-domain resource allocation (TDRA) field and the PDSCH-to-HARQ feedback timing indicator field may indicate the value of the slot parameter: k=k0+k1. In some aspects, the RRC message may indicate the value k of the slot parameter. In some aspects, the value k of the slot parameter may be zero, and the second slot may comprise the last slot of the PUCCH transmission that overlaps with the reception of the DCI transmission.

[0069]

[0073] In some aspects, the UE 305 may transmit HARQ feedback using a PUCCH resource having an index. The UE 305 may determine the PUCCH resource based at least in part on a PUCCH resource indicator field of a DCI transmission. In some aspects, the UE 305 may determine the PUCCH resource based at least in part on an RRC message.

[0070]

[0074] The HARQ feedback transmitted by the UE 305 may include one ACK or NACK bit and may be transmitted using a HARQ-ACK codebook. For example, in some aspects, the UE 305 may transmit the HARQ feedback using a dynamic HARQ-ACK codebook (e.g., a Type II HARQ codebook). In some aspects, for example, the UE 305 may use the dynamic HARQ codebook based at least in part on receiving the RRC parameter value pdsch-HARQ-ACK-Codebook=dynamic. The DCI format of the DCI transmission may include a downlink allocation index (DAI) field, and the UE 305 may determine an ACK / NACK position in the dynamic HARQ-ACK codebook for the HARQ feedback responsive to the TCI indication in the DCI based at least in part on the DAI value indicated in the DCI. The DAI value may include a counter DAI value. In some aspects, the DAI value may include a counter DAI value and a total DAI value.

[0071]

[0075] In some aspects, the UE 305 may transmit HARQ feedback using a static HARQ-ACK codebook. For example, the ACK / NACK location may include the first bit of the static HARQ-ACK codebook. In some aspects, for example, the UE 305 may use the static HARQ codebook based at least in part on receiving an RRC parameter value pdsch-HARQ-ACK-Codebook=semi-static. The DCI format of the DCI transmission may include a time-domain resource allocation field indicating a virtual PDSCH opportunity. For example, in some aspects, the UE 305 may determine an ACK / NACK location in the static HARQ-ACK codebook for HARQ feedback responsive to a TCI indication in the DCI based at least in part on the virtual PDSCH opportunity. In some aspects, the UE 305 may determine a location in the static HARQ-ACK codebook for HARQ feedback based at least in part on an entry in a time-domain allocation list indicating a virtual PDSCH. In some aspects, the TDRA field may include a Start and Length Indicator Value (SLIV), and the UE 305 may determine a location within a static HARQ-ACK codebook for the HARQ feedback based at least in part on the SLIV.

[0072]

[0076] As noted above, the RRC message can indicate an ACK / NACK location, and the UE 305 can determine a location in a static HARQ-ACK codebook for the HARQ feedback based at least in part on the RRC message. In some aspects, the RRC message can indicate an associated PDSCH opportunity, and the UE 305 can determine a location in a static HARQ-ACK codebook for the HARQ feedback based at least in part on the RRC message. In some aspects, the UE 305 may base the determination at least in part on an entry in a time domain allocation list that indicates the PDSCH opportunity.

[0073]

[0077] In some aspects, the UE 305 may determine a location in a static HARQ-ACK codebook for HARQ feedback based at least in part on a dedicated bit position in the static HARQ-ACK codebook. For example, a DCI transmission may indicate a dedicated bit position. In some aspects, if the DCI does not indicate a location, a NACK may be filled in the dedicated bit. In some aspects, the dedicated bit position may include the first bit of the static HARQ-ACK codebook or the last bit of the static HARQ-ACK codebook.

[0074]

[0078] In some aspects, the UE 305 may append one or more dedicated bits to the end of the static HARQ-ACK codebook based at least in part on the DCI transmission. For example, in some aspects, the UE 305 may determine that the aggregate TCI includes an updated TCI, and based at least in part on that determination, the UE 305 may append one or more dedicated bits to the end of the static HARQ-ACK codebook.

[0075]

[0079] In some aspects, similar techniques may be used to indicate HARQ feedback associated with several DCI transmissions. For example, the UE 305 may receive an additional DCI transmission indicating an additional aggregate TCI that does not include a downlink assignment. In some aspects, the HARQ feedback may include a first ACK / NACK bit corresponding to the DCI transmission and a second ACK / NACK bit corresponding to the additional DCI transmission.

[0076]

[0080] For example, the UE 305 may determine a first position of a first ACK / NACK bit based at least in part on at least one of a first ACK / NACK position associated with the first DCI transmission or a first PDSCH opportunity associated with the first DCI transmission, and may determine a second position of a second ACK / NACK bit based at least in part on at least one of a second ACK / NACK position associated with the second DCI transmission or a second PDSCH opportunity associated with the second DCI transmission. In some aspects, the first DCI transmission may indicate at least one of the first ACK / NACK position associated with the first DCI transmission or the first PDSCH opportunity associated with the first DCI transmission, and the second DCI transmission may indicate at least one of the second ACK / NACK position associated with the second DCI transmission or the second PDSCH opportunity associated with the second DCI transmission.

[0077]

[0081] In some aspects, the first DCI transmission may include a first TDRA field indicating at least one of the first ACK / NACK locations, and the second DCI transmission may include a second TDRA field indicating at least one of the second ACK / NACK locations. In some aspects, the first TDRA field may include a first SLIV indicating at least one of the first ACK / NACK locations, and the second TDRA transmission field may include a second SLIV indicating at least one of the second ACK / NACK locations.

[0078]

[0082] In some aspects, the UE 305 may determine a first position of a first ACK / NACK bit based at least in part on a mapping rule that maps a first ID of a first indication within a first DCI transmission with at least one of a first ACK / NACK position associated with the first DCI transmission or a first PDSCH opportunity associated with the first DCI transmission. For example, the first ID may include at least one of a first TCI codepoint, a first PDCCH monitoring opportunity, or a first HARQ ID field. The UE 305 may determine a position of a second ACK / NACK bit based at least in part on a mapping rule that maps a second ID of a second indication within a second DCI transmission with at least one of a second ACK / NACK position associated with the second DCI transmission or a second PDSCH opportunity associated with the second DCI transmission. The second ID may include at least one of a second TCI codepoint, a second PDCCH monitoring opportunity, or a second HARQ ID field.

[0079]

[0083] In some aspects, the UE 305 can determine a first position of the first ACK / NACK bit based at least in part on a dedicated fixed-size position appended to an end of the static HARQ-ACK codebook and can determine a second position of the first ACK / NACK bit based at least in part on a dedicated fixed-size position appended to an end of the static HARQ-ACK codebook. The dedicated fixed-size position may indicate an aggregate TCI and may include a number of bits greater than the number of received DCI transmissions with no downlink assignment. In some aspects, the UE 305 can determine a first position of the first ACK / NACK bit based at least in part on a dynamic position appended to an end of the static HARQ-ACK codebook and can determine a second position of the first ACK / NACK bit based at least in part on a dynamic position appended to an end of the static HARQ-ACK codebook.

[0080]

[0084] In some aspects, the UE 305 can receive a DCI transmission associated with the PDSCH opportunity and can receive a PDSCH transmission associated with the PDSCH opportunity. The UE 305 can transmit HARQ feedback based at least in part on the rule. In some aspects, the UE 305 can transmit HARQ feedback based at least in part on increasing the size of an HARQ-ACK codebook used to transmit the HARQ feedback. The UE 305 can append ACK / NACK bits corresponding to the DCI transmission to the end of the HARQ-ACK codebook. In some aspects, the UE 305 can append ACK / NACK bits corresponding to the DCI transmission adjacent to ACK / NACK bits corresponding to the PDSCH transmission in the HARQ-ACK codebook.

[0081]

[0085] As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

[0086] 4 is a diagram illustrating an example 400 relating to feedback corresponding to an aggregated TCI in a DCI without a downlink assignment in accordance with the present disclosure. As illustrated, a UE 405 and a base station 410 can communicate with each other. In some aspects, the UE 405 can be or be similar to the UE 305 shown in FIG. 3. The base station 410 can be or be similar to the base station 310 shown in FIG. 3.

[0083]

[0087] As shown, the UE 405 may receive a DCI transmission from the base station 410 indicating an aggregate TCI (denoted as “DCI (TCI)”) associated with the physical downlink control channel (PDCCH) in slot n. + One or more PUCCH resources 415 of a set 420 of PUCCH resources in slot n may be used to transmit HARQ feedback indicating an ACK or NACK (denoted as "A / N").+ k and / or the one or more PUCCH resources 415 may be determined as described above in connection with FIG.

[0084]

[0088] For example, in some aspects, a DCI transmission for a beam indication without a downlink assignment (e.g., an integrated TCI indication) may include DCI format 1_1 or 1_2. Upon successful reception of the beam indication DCI, the UE 405 may report an ACK to the base station, and upon unsuccessful reception of the beam indication DCI, the UE 405 may report a NACK to the base station.

[0085]

[0089] One or more PUCCH resources 415 may be used to transmit a HARQ-ACK codebook of multiple ACK / NACK bits, including at least one of the ACK / NACK bits for HARQ feedback corresponding to a beam indication in a DCI without any downlink assignment. The HARQ-ACK codebook may be configured as a Type 1 HARQ-ACK codebook (e.g., with the RRC parameter pdsch-HARQ-ACK-Codebook=static) or a Type 2 HARQ-ACK codebook (e.g., with the RRC parameter pdsch-HARQ-ACK-Codebook=dynamic). In some aspects, for example, in the case of a Type 1 HARQ-ACK codebook, an ACK / NACK position in the HARQ-ACK codebook for ACK / NACK information responsive to a beam indication in a DCI without any downlink assignment may be determined based on a virtual PDSCH opportunity indicated by a TDRA field in the DCI and based on a time domain allocation list configured for the PDSCH. For example, the time domain allocation list may be based on the RRC configured pdsch-TimeDomainAllocationList. The virtual PDSCH opportunity only provides a reference or index to identify a PDSCH opportunity among multiple candidate PDSCH opportunities configured by an RRC message, and the UE does not receive any signals within the virtual PDSCH opportunity.

[0086]

[0090] In some other aspects, for a Type 1 HARQ-ACK codebook, the UE 405 may determine an ACK / NACK location in the HARQ-ACK codebook for ACK / NACK information responsive to a beam indication in a DCI without any downlink assignment based at least in part on the virtual PDSCH opportunity identified by the multiple indications together. 1) If present, the TDRA field in the DCI; otherwise, the TDRA indication configured in the RRC message pdsch-TimeDomainAllocationList. 2) If present, the PDSCH-to-HARQ_feedback timing indicator field in the DCI, otherwise the dl-DataToUL-ACK (or dl-DataToUL-ACK-ForDCI-Format1-2-r16) in the RRC message. 3) DL slot index associated with DCI or virtual PDSCH if one uplink slot overlaps with multiple downlink slots based on the downlink and uplink numerology in the serving cell.

[0087]

[0091] In some aspects, in the case of a Type 2 HARQ-ACK codebook, the UE 405 may determine an ACK / NACK position in the HARQ-ACK codebook for ACK / NACK information responsive to a beam indication in a DCI without any downlink assignment based at least in part on the DAI field in the DCI. In some aspects, in the case of a Type 2 HARQ-ACK codebook, the ACK / NACK position in the HARQ-ACK codebook for ACK / NACK information responsive to a beam indication in a DCI without any downlink assignment may be determined based on the same rules as determining the ACK / NACK position in the HARQ-ACK codebook for ACK information in a HARQ-ACK codebook responsive to a semi-persistent scheduling (SPS) release DCI.

[0088]

[0092] In some aspects, ACK / NACK information responsive to the beam indication in the DCI may be transmitted in the PUCCH k slots after the end of the PDCCH reception for the DCI, where k is indicated by the PDSCH-to-HARQ_feedback timing indicator field of the DCI format, or provided by dl-DataToUL-ACK (or dl-DataToUL-ACK-ForDCI-Format1-2-r16) if the PDSCH-to-HARQ_feedback timing indicator field is not present in the DCI.

[0089]

[0093] In some aspects, for a Type 2 HARQ-ACK codebook, the UE 405 may report HARQ-ACK information for DCI-only beam indications in the HARQ-ACK codebook that the UE transmits in slots indicated by the value of the PDSCH-to-HARQ_feedback timing indicator field of the corresponding DCI format 1_0 or DCI format 1_1. The UE reports NACK values ​​for HARQ-ACK information bits in the HARQ-ACK codebook that the UE transmits in slots not indicated by the value of the PDSCH-to-HARQ_feedback timing indicator field of the corresponding DCI format 1_0 or DCI format 1_1.

[0090]

[0094] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0091]

[0095] 5 is a diagram illustrating an example 500 relating to feedback corresponding to an aggregated TCI in a DCI without a downlink assignment in accordance with the present disclosure. As illustrated, a UE 505 and a base station 510 can communicate with each other. In some aspects, the UE 505 can be or be similar to the UE 305 shown in FIG. 3. The base station 510 can be or be similar to the base station 310 shown in FIG. 3.

[0092]

[0096] As shown, the UE 505 may receive a DCI transmission from the base station 510 indicating an aggregate TCI (denoted as "DCI(TCI)") associated with the PDCCH 515. The UE 505 may transmit HARQ feedback indicating an ACK or NACK corresponding to the TCI (denoted as "A / N(TCI)") using a position 520 in the HARQ-ACK codebook (denoted as "HARQ codebook"). For example, the position 520 may be determined based on a counter DAI (C-DAI) indicated in the DCI with no downlink assignment. In one example, the DCI(TCI) may indicate a value of 1, which corresponds to the C-DAI. The position 520 may correspond to C-DAI=1.

[0093]

[0097] As noted above, Figure 5 is provided as an example. Other examples may differ from those described with respect to Figure 5.

[0094]

[0098] 6 is a diagram illustrating an example 600 relating to feedback corresponding to aggregated TCI in DCI without downlink assignments in accordance with the present disclosure. Example 600 illustrates use of a static HARQ-ACK codebook (e.g., a Type I HARQ-ACK codebook) in accordance with some aspects.

[0095]

[0099] In some aspects, if a UE receives an aggregated TCI indicated by a DCI without any downlink assignment and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in a Type I HARQ codebook for the DCI, and the position of the A / N bit in the HARQ codebook responsive to the TCI indication in the DCI is the same as the position for the PDSCH opportunity indicated in the TDRA field with the DCI. In some aspects, the UE may determine the position of the A / N bit in the HARQ codebook responsive to the TCI indication in the DCI based on the assumption that the PDSCH opportunity is located in the same slot as the DCI. In some aspects, the UE may expect the indicated TDRA of the DCI to correspond to the A / N bit in the HARQ codebook.

[0096]

[0100] As shown in FIG. 6, for example, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH (e.g., DCI transmission) that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, unused bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may be included in a position corresponding to the associated PDSCH, which may be determined at least in part based on the TDRA and / or SLIV within the DCI. At time 3, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bits corresponding to the TCI may be included in dedicated positions corresponding to different associated PDSCHs, which may be determined at least in part based on the TDRA and / or the SLIV.

[0097]

[0101] As noted above, Figure 6 is provided as an example. Other examples may differ from those described with respect to Figure 6.

[0098]

[0102] 7 illustrates an example 700 relating to feedback corresponding to aggregated TCI in DCI without downlink assignments in accordance with the present disclosure. Example 700 illustrates use of a static HARQ-ACK codebook (e.g., a Type I HARQ-ACK codebook) in accordance with some aspects.

[0099]

[0103] In some aspects, if a UE receives an aggregated TCI indicated by a DCI without any downlink assignment and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in the Type I HARQ codebook for the DCI, where the position of the A / N for the DCI is the same as for the PDSCH opportunity configured associated with the DCI of the aggregated TCI without any downlink assignment indication.

[0100]

[0104] For example, as shown in FIG. 7, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, unused bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may be included in a position associated with the PDCCH (TCI). At time 3, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may correspond to an associated PDSCH opportunity configured by the RRC configuration, or may be included in a dedicated position that is a default position (e.g., associated with the first A / N bit in the HARQ codebook or the PDSCH opportunity identified by the first entry in the pdsch-TimeDomainAllocationList).

[0101]

[0105] As noted above, Figure 7 is provided as an example. Other examples may differ from those described with respect to Figure 7.

[0102]

[0106] 8 illustrates an example 800 relating to feedback corresponding to aggregated TCI within a DCI with no downlink allocation, in accordance with the present disclosure. Example 800 illustrates the use of a static HARQ-ACK codebook with a fixed codebook size (e.g., a Type I HARQ-ACK codebook).

[0103]

[0107] In some aspects, if a UE receives an aggregated TCI indicated by a DCI without any downlink assignment and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in the Type I HARQ codebook for the DCI, where the A / N position is the bit appended after the HARQ-ACK information for PDSCH reception. In some aspects, the UE may append a NACK if no DCI is received for an aggregated TCI indication without any DL assignment. In some aspects, the UE does not append a NACK bit if no DCI is received for an aggregated TCI indication without any DL assignment.

[0104]

[0108] In some aspects, the location of the A / N may be the first bit in the codebook as shown in FIG. 8. For example, as shown, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, the unused TCI dedicated bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including two A / N bits associated with each PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bits corresponding to the TCI may be included in a default position, such as the first bit of the codebook. At time 3, the UE may transmit a HARQ codebook including two A / N bits associated with each PDCCH that schedules a PDSCH.

[0105]

[0109] As noted above, Figure 8 is provided as an example. Other examples may differ from those described with respect to Figure 8.

[0106]

[0110] 9 is a diagram illustrating an example 900 relating to feedback corresponding to aggregated TCI in DCI without downlink allocation, in accordance with the present disclosure. Example 900 illustrates the use of a static HARQ-ACK codebook (e.g., a Type I HARQ-ACK codebook) where the codebook size may vary.

[0107]

[0111] For example, as shown, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, unused TCI-dedicated bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including two A / N bits associated with each PDCCH that schedules a PDSCH and an appended A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may be appended as the first bit of the codebook. At time 3, the UE may transmit a HARQ codebook including two A / N bits associated with each PDCCH that schedules a PDSCH.

[0108]

[0112] As noted above, Figure 9 is provided as an example. Other examples may differ from those described with respect to Figure 9.

[0109]

[0113] 10 illustrates an example 1000 relating to feedback corresponding to aggregated TCI in DCI with no downlink allocation, in accordance with the present disclosure. Example 1000 illustrates the use of a static HARQ-ACK codebook with a fixed codebook size (e.g., a Type I HARQ-ACK codebook).

[0110]

[0114] In some aspects, if a UE receives multiple aggregated TCIs indicated by DCIs without any downlink assignments and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in the Type I HARQ codebook in response to each DCI, where the location of the A / N for the DCI is determined based on the PDSCH opportunity identified by the TDRA field in the DCI. In some aspects, the UE may expect the indicated TDRA of the DCI to correspond to the A / N in the HARQ codebook.

[0111]

[0115] For example, as shown in FIG. 10, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, unused bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may be included in a position associated with the PDCCH (TCI). At time 3, the UE may transmit a HARQ codebook including a first A / N bit in a first position (denoted as "loc1") associated with a first PDCCH indicating a TCI (denoted as PDCCH(TCI1)) that does not include a downlink assignment, and a second A / N bit associated with a second PDCCH indicating a TCI (denoted as PDCCH(TCI2)) that does not include a downlink assignment. An A / N bit corresponding to a TCI may be included in each position associated with a PDCCH.

[0112]

[0116] As noted above, Figure 10 is provided as an example. Other examples may differ from those described with respect to Figure 10.

[0113]

[0117] 11 illustrates an example 1100 relating to feedback corresponding to aggregated TCI within a DCI with no downlink allocation, in accordance with the present disclosure. Example 1100 illustrates the use of a static HARQ-ACK codebook with a fixed codebook size (e.g., a Type I HARQ-ACK codebook).

[0114]

[0118] In some aspects, if a UE receives multiple aggregated TCIs indicated by DCIs without any downlink assignments and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in the Type I HARQ codebook for each DCI, and the location of the A / N for each DCI is the same as for the configured PDSCH opportunity associated with the aggregated TCI indication. The location may be indicated using an RRC configuration that can map an ID to a location.

[0115]

[0119] For example, as shown in FIG. 11, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. As shown, unused bits may be filled with NACKs (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including an A / N bit associated with a PDCCH that schedules a PDSCH and an A / N bit associated with a PDCCH that indicates a TCI that does not include a downlink assignment. The A / N bit corresponding to the TCI may be included in a first position associated with the PDCCH (TCI) based on a mapping that maps a first TCI codepoint (denoted as "TCI codepoint 0") to a first position (denoted as "Loc1]). At time 3, the UE may transmit a HARQ codebook including a first A / N bit in a first location (denoted as "Loc1") associated with a first PDCCH indicating a TCI (denoted as PDCCH(TCI1)) that does not include a downlink allocation and a second A / N bit in a second location (denoted as "Loc2") associated with a second PDCCH indicating a TCI (denoted as PDCCH(TCI2)) that does not include a downlink allocation. The second location associated with the PDCCH(TCI) may be based on a mapping that maps a second TCI codepoint (denoted as "TCI codepoint 1") to the second location (denoted as "Loc2").

[0116]

[0120] In some aspects, the mapping between ACK / NACK information responding to DCIs having a TCI indication that does not include any downlink assignment and configured or default positions in the HARQ codebook may be predetermined by a default order or an RRC-configured order. For example, ACK / NACK information responding to DCIs having a TCI indication using a first TCI codepoint may be mapped to a first default position in the HARQ codebook, and ACK / NACK information responding to DCIs having a TCI indication using a second TCI codepoint may be mapped to a second default position in the HARQ codebook. In some other aspects, an HARQ ID field in a DCI having a TCI indication that does not include any downlink assignment may be used to determine the ACK / NACK position in the HARQ codebook. For example, ACK / NACK information responsive to a DCI having a TCI indication using a first HARQ ID may be mapped to a first default location of the HARQ codebook, and ACK / NACK information responsive to a DCI having a TCI indication using a second HARQ ID may be mapped to a second default location of the HARQ codebook. In some other aspects, a PDCCH monitoring opportunity index having a DCI having a TCI indication that does not include any downlink assignment may be used to determine the ACK / NACK location in the HARQ codebook. For example, ACK / NACK information responsive to a DCI having a TCI indication in a first PDCCH monitoring opportunity index may be mapped to a first default location of the HARQ codebook, and ACK / NACK information responsive to a DCI having a TCI indication in a second PDCCH monitoring opportunity index may be mapped to a second default location of the HARQ codebook.

[0117]

[0121] As noted above, Figure 11 is provided as an example. Other examples may differ from those described with respect to Figure 11.

[0118]

[0122] 12 illustrates an example 1200 relating to feedback corresponding to aggregated TCI within a DCI with no downlink allocation, in accordance with the present disclosure. Example 1200 illustrates the use of a static HARQ-ACK codebook with a fixed codebook size (e.g., a Type I HARQ-ACK codebook).

[0119]

[0123] In some aspects, if a UE receives multiple aggregated TCIs indicated by multiple DCIs without any downlink assignments and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in a Type I HARQ codebook for each DCI, and the A / N positions are a fixed number of bits appended after the HARQ-ACK information for PDSCH reception. The UE may append a NACK if no DCI is received for the aggregated TCI indication without any DL assignments. In some aspects, the fixed number of bits may be appended as the first bits in the codebook.

[0120]

[0124] For example, as shown, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. The codebook may also include an A / N associated with the first PDCCH that indicates a TCI (denoted as PDCCH(TCI1)) within dedicated appended bits. As shown, the unused TCI dedicated bits may be filled with a NACK (denoted as "N"). At time 2, the UE may transmit a HARQ codebook that includes two A / N bits associated with each PDCCH that schedules a PDSCH and two A / N bits associated with two respective PDCCHs that indicate TCIs that do not include a downlink assignment (denoted as PDCCH(TCI1) and PDCCH(TCI2)). At time 3, the UE may transmit a HARQ codebook that includes two A / N bits associated with each PDCCH that schedules a PDSCH and may include N unused bits.

[0121]

[0125] As noted above, Figure 12 is provided as an example. Other examples may differ from those described with respect to Figure 12.

[0122]

[0126] 13 illustrates an example 1300 relating to feedback corresponding to aggregated TCI within a DCI with no downlink allocation, in accordance with the present disclosure. Example 1300 illustrates the use of a static HARQ-ACK codebook (e.g., a Type I HARQ-ACK codebook) where the codebook size may vary.

[0123]

[0127] In some aspects, the UE may not append any bits if no DCI is received for an aggregate TCI indication without any DL assignment. For example, as shown, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH scheduling a PDSCH and a second A / N bit associated with a second PDCCH scheduling a second PDSCH. The codebook may also include an A / N associated with the first PDCCH indicating a TCI (denoted as PDCCH(TCI1)) within dedicated appended bits. As shown, unused TCI-only bits may be filled with a NACK (denoted as "N"). At time 2, the UE may transmit a HARQ codebook including two A / N bits associated with respective PDCCHs scheduling a PDSCH and two A / N bits associated with two respective PDCCHs indicating TCIs that do not include a downlink assignment (denoted as PDCCH(TCI1) and PDCCH(TCI2)). At time 3, the UE may transmit a HARQ codebook containing two A / N bits associated with each PDCCH that schedules a PDSCH. As shown, the codebook may not have an A / N bit appended if a PDCCH with a TCI was not received.

[0124]

[0128] As noted above, Figure 13 is provided as an example. Other examples may differ from those described with respect to Figure 13.

[0125]

[0129] 14 illustrates an example 1400 relating to feedback corresponding to aggregated TCI within a DCI with no downlink allocation, in accordance with the present disclosure. Example 1400 illustrates the use of a static HARQ-ACK codebook (e.g., a Type I HARQ-ACK codebook) where the codebook size may vary.

[0126]

[0130] In some aspects, if a UE receives multiple aggregated TCIs indicated by multiple DCIs without any downlink assignment and is provided with pdsch-HARQ-ACK-Codebook=semi-static, the UE may generate one A / N bit in the Type I HARQ codebook for the DCI, where the position of the A / N is the bit appended after the HARQ-ACK information for PDSCH reception. In some aspects, the UE may not append a NACK if no DCI is received for an aggregated TCI indication without any DL assignment.

[0127]

[0131] In some aspects, the position of the appended A / N bit may be at the beginning of the codebook. For example, as shown in FIG. 14, at time 1, the UE may transmit a HARQ codebook including an A / N bit associated with a first PDCCH that schedules a PDSCH and a second A / N bit associated with a second PDCCH that schedules a second PDSCH. At time 2, the UE may transmit a codebook that may also include an A / N associated with a first PDCCH that indicates a TCI (denoted as PDCCH(TCI1)) within the appended bits. As shown, unused TCI-only bits may be filled with a NACK (denoted as "N"). At time 3, the UE may transmit a HARQ codebook that includes two A / N bits associated with respective PDCCHs that schedule a PDSCH and two appended A / N bits associated with two respective PDCCHs that indicate TCIs that do not include a downlink assignment (denoted as PDCCH(TCI1) and PDCCH(TCI2)).

[0128]

[0132] As noted above, Figure 14 is provided as an example. Other examples may differ from those described with respect to Figure 14.

[0129]

[0133] 15 illustrates an example process 1500, performed, for example, by a UE, in accordance with the present disclosure. The example process 1500 is an example in which a UE (e.g., UE 305) performs operations associated with feedback corresponding to aggregated TCI in DCI that has no downlink assignment.

[0130]

[0134] 15, in some aspects, process 1500 may include receiving, in a first slot, a DCI transmission indicating the consolidated TCI, the DCI transmission not including a downlink assignment (block 1510). For example, a UE may receive, in a first slot (e.g., using the receiving component 1702 depicted in FIG. 17), a DCI transmission indicating the consolidated TCI, the DCI transmission not including a downlink assignment, as described above.

[0131]

[0135] 15, in some aspects, process 1500 may include transmitting HARQ feedback corresponding to the aggregated TCI, where the HARQ feedback comprises an ACK indicating successful reception of the aggregated TCI within the DCI transmission or a NACK indicating unsuccessful reception of the aggregated TCI within the DCI transmission (block 1520). For example, the UE may transmit HARQ feedback corresponding to the aggregated TCI (e.g., using the transmitting component 1704 depicted in FIG. 17), where the HARQ feedback comprises an ACK indicating successful reception of the aggregated TCI within the DCI transmission or a NACK indicating unsuccessful reception of the aggregated TCI within the DCI transmission, as described above.

[0132]

[0136] Process 1500 may include additional aspects, such as any single aspect or any combination of aspects, described below and / or in connection with one or more other processes described elsewhere herein.

[0133]

[0137] In a first aspect, transmitting the HARQ feedback comprises transmitting the HARQ feedback using a PUCCH transmission in a second slot, the second slot being separated from the first slot by a number of slots indicated by a value of the slot parameter.

[0134]

[0138] In a second aspect, alone or in combination with the first aspect, the DCI transmission comprises a PDSCH-to-HARQ feedback timing indicator field, the PDSCH-to-HARQ feedback timing indicator field indicating a value of a slot parameter.

[0135]

[0139] In a third aspect, alone or in combination with one or more of the first and second aspects, the DCI transmission comprises a PDSCH-to-HARQ feedback timing indicator field and a time domain resource allocation (TDRA) field, and the sum of the values ​​of the TDRA field and the PDSCH-to-HARQ feedback timing indicator field indicates the value of a slot parameter.

[0136]

[0140] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the process 1500 includes receiving a radio resource control message indicating a value of a slot parameter.

[0137]

[0141] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the value of the slot parameter is zero and the second slot comprises the last slot of the PUCCH transmission that overlaps with the reception of the DCI transmission.

[0138]

[0142] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, transmitting the HARQ feedback comprises transmitting the HARQ feedback using a PUCCH resource having an index.

[0139]

[0143] In a seventh aspect, alone or in combination with the sixth aspect, the process 1500 includes determining a PUCCH resource based at least in part on a PUCCH indicator field of a DCI transmission.

[0140]
