Description

[0001] This application is a divisional application of Chinese Patent Application No. 202080106351.4, filed on October 21, 2020, entitled “Systems and Methods for Downlink Control Information Re-transmission Related to Beam Indication Using Hybrid Automatic Repeat Request Acknowledgement Procedure,” the disclosure of which is incorporated by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates generally to wireless communications, including but not limited to systems and methods for downlink control information (DCI) re-transmission related to beam indication using hybrid automatic repeat request acknowledgement (HARQ-ACK) procedure. BACKGROUND

[0003] The Third Generation Partnership Project (3GPP) standardization organization is currently specifying a new radio interface, referred to as 5G New Radio (5G NR), and a next generation packet core network (NG-CN or NGC). 5G NR will have three main components: a 5G access network (5G-AN), a 5G core network (5GC), and a user equipment (UE). To facilitate the implementation of different data services and needs, the units of the 5GC (also referred to as network functions) have been simplified, some of which are software-based and some of which are hardware-based so that they can be adjusted as needed. SUMMARY

[0004] The example embodiments disclosed herein are directed to addressing issues related to one or more problems with the prior art and provide additional features that will be apparent in connection with the following details as described in connection with the drawings. In accordance with various embodiments, example systems, methods, devices, and computer program products are disclosed herein. It should be understood, however, that these embodiments are presented by way of example and not limitation, and that the disclosure is equally applicable to any number of other systems, methods, devices, and computer program products that fall within the scope of the disclosure.

[0005] At least one aspect is directed to a system, method, apparatus, or computer readable medium. A wireless communication device can receive, from a wireless communication node, downlink control information. The wireless communication device can determine a location of hybrid automatic repeat request acknowledgement (HARQ-ACK) information for a procedure associated with the DCI in a HARQ-ACK codebook. The wireless communication device can determine a first physical uplink control channel (PUCCH) resource. The wireless communication device can transmit, to the wireless communication node, a PUCCH transmission carrying the HARQ-ACK information.

[0006] In some embodiments, the procedure can include at least one of a reference channel determination, a downlink (DL) channel reception, a DL channel release, a DCI reception, a physical downlink control channel (PDCCH) reception, or a beam state indication. In some embodiments, a first PUCCH resource can be configured for the procedure using radio resource control (RRC) signaling or medium access control control element (MAC CE) signaling. In some embodiments, the first PUCCH resource can be indicated by a PUCCH resource indicator (PRI) in the DCI. In some embodiments, a HARQ-ACK codebook can be carried by a second PUCCH resource. In some embodiments, the wireless communication device can determine the second PUCCH resource from a set of PUCCH resources associated with a same time unit for PUCCH transmission corresponding to the HARQ-ACK information. In some embodiments, the set of PUCCH resources includes at least one candidate resource for carrying PUCCH transmission of one or more HARQ-ACK information.

[0007] In some embodiments, a time offset between the DCI and the PUCCH transmission can be determined according to a first parameter. In some embodiments, the first parameter can be configured according to a predefined configuration, a capability of the wireless communication device, radio resource control (RRC) signaling, medium access control control element (MAC CE) signaling, or another DCI. In some embodiments, the first parameter can indicate a number of available UL time units relative to a time unit of the DCI. In some embodiments, the PUCCH transmission can be in a first uplink time unit after the time unit of the DCI. In some embodiments, a location of the HARQ-ACK information in the HARQ-ACK codebook can correspond to a first bit, a last bit, or a predefined bit of the HARQ-ACK codebook. In some embodiments, the HARQ-ACK information can be located before or after a HARQ-ACK codebook for an associated physical downlink shared channel (PDSCH) reception or release.

[0008] In some embodiments, if the wireless communication device fails to detect the DCI, the wireless communication device can generate a non-acknowledgement (NACK) value for the HARQ-ACK information. In some embodiments, if the wireless communication device detects the DCI, the wireless communication device can generate an acknowledgement (ACK) value for the HARQ-ACK information. In some embodiments, the DCI can trigger / include an indication of a beam state. In some embodiments, the beam state can be applied to downlink or uplink signals Q time units after transmitting the HARQ-ACK information. In some embodiments, Q can be determined according to a predefined configuration, a capability of the wireless communication device, radio resource control (RRC) signaling, medium access control control element (MAC CE) signaling, or another DCI.

[0009] In some embodiments, a pattern of the HARQ-ACK codebook can be configured to be “semi-static.” In some embodiments, a location of the HARQ-ACK information can be determined according to at least one of a time offset from a downlink data channel to a corresponding HARQ-ACK, a time domain resource parameter, a subcarrier spacing of the downlink, a subcarrier spacing of the uplink, or at least one parameter of a downlink and uplink pattern. In some embodiments, the time offset can be indicated or selected from a set of time offsets from a downlink data channel to a corresponding HARQ-ACK. In some embodiments, the time offset can be indicated or selected from a set of default time offsets from a downlink data channel to a corresponding HARQ-ACK if the DCI has a DCI format 1_0 or the set of time offsets is not configured. In some embodiments, the time offset can indicate a number of available uplink time units relative to time units of the DCI. In some embodiments, the time domain resource parameter can be indicated or selected from a set of time domain resource parameters of the downlink signal. In some embodiments, the procedure can include a reference channel determination. In some embodiments, the reference channel can be associated with the time domain resource parameter. In some embodiments, the reference channel can be used to determine a location of the HARQ-ACK information in the HARQ-ACK codebook.

[0010] In some embodiments, the reference channel determination can be in the same time unit as the DCI. In some embodiments, a slot offset between the DCI and the reference channel determination, a slot offset between the DCI and the DL channel reception, or a slot offset between the DCI and the DL channel release can be zero. In some embodiments, a location of the HARQ-ACK information can be the same as a location of HARQ-ACK information corresponding to the reference channel or the downlink (DL) channel reception determined using the time domain resource parameter. In some embodiments, a mode of the HARQ-ACK codebook can be configured as “dynamic.” In some embodiments, the location of the HARQ-ACK information can be determined according to at least one of: a time offset from the DCI or an associated physical downlink control channel (PDCCH) to the HARQ-ACK information, a time offset from the DCI or an associated PDCCH to a downlink data channel (e.g., PDSCH), a time offset from the downlink data channel (e.g., PDSCH) to the HARQ-ACK information, a PDCCH monitoring occasion, or a downlink assignment index (DAI) parameter.

[0011] In some embodiments, the DAI parameter can include at least one of a counter DAI and a total DAI. In some embodiments, the DAI parameter can be associated with a control resource set (CORESET) pool identifier (ID) or a set of one or more DCI formats. In some embodiments, the wireless communication device can determine a counter for bits of the HARQ-ACK information according to a value of the counter DAI. In some embodiments, the DCI can include the value of the counter DAI. In some embodiments, the value of the counter DAI can be less than a value of the total DAI after a last monitored occasion. In some embodiments, the counter for bits of the HARQ-ACK information can have a value of the value of the counter DAI + 1.

[0012] In some embodiments, a wireless communication device can receive radio resource control (RRC) signaling or a medium access control control element (MAC CE) from a wireless communication node. In some embodiments, the RRC signaling or MAC CE signaling can configure or reconfigure one or more parameters corresponding to the DCI. In some embodiments, the one or more parameters can include at least one of: a particular radio network temporary identifier (RNTI), a starting bit indication parameter, a number of indicated beam states, or a type of HARQ-ACK process (including semi-static or dynamic) corresponding to the DCI. In some embodiments, the one or more parameters can include at least one of: support for a downlink assignment index (DAI) or a total DAI field in the DCI, one or more control resource sets (CORESETs) or search space sets associated with the DCI, a CORESET pool identifier (ID), an ID of the wireless communication device, or an antenna group of the wireless communication device.

In some embodiments, the wireless communication device can receive the configuration in response to a sounding reference signal (SRS), a physical uplink control channel (PUCCH), and a physical uplink shared channel (PUSCH) not being configured with spatial relation information. In some embodiments, the wireless communication device can receive the configuration in response to the SRS, the PUSCH, and the PUCCH not being configured with uplink power control parameters. In some embodiments, the wireless communication device can receive the configuration in response to particular radio resource control (RRC) signaling.

[0014] In some embodiments, the SRS, the PUSCH, and the PUCCH can not be configured with a parameter of a path loss reference signal (PL-RS). In some embodiments, the SRS associated with the PUSCH can not be configured with the parameter of the PL-RS. In some embodiments, the SRS for non-codebook or codebook transmission can not be configured with the parameter of the PL-RS. In some embodiments, a number of HARQ processes field in the DCI can be set to a particular value. In some embodiments, a redundancy version field in the DCI can be set to a particular value. In some embodiments, a modulation and coding scheme (MCS) field in the DCI can be set to a particular value.

[0018] In some embodiments, if the wireless communication device fails to detect the DCI, the wireless communication device can generate a non-acknowledgement (NACK) value for the HARQ-ACK information. In some embodiments, if the wireless communication device detects the DCI, the wireless communication device can generate an acknowledgement (ACK) value for the HARQ-ACK information. In some embodiments, the DCI can trigger / include an indication of a beam state. In some embodiments, the beam state can be applied to downlink or uplink signals Q time units after transmitting the HARQ-ACK information, e.g., when the trigger / indication occurs. In some embodiments, Q can be determined according to a predefined configuration, a capability of the wireless communication device, radio resource control (RRC) signaling, medium access control control element (MAC CE) signaling, or another DCI.

[0039] 1、 Mobile communication technology and environment

[0040] Figure 1An example wireless communication network and / or system 100 in which the technology disclosed herein can be implemented is shown in accordance with embodiments of the present disclosure. In the following discussion, the wireless communication network 100 can be any wireless network such as a cellular network or a Narrow Band Internet of Things (NB-IoT) network, and is referred to herein as "network 100." Such example network 100 includes base stations 102 (hereinafter "BS 102"; also referred to as wireless communication nodes) and user equipment terminals 104 (hereinafter "UE 104"; also referred to as wireless communication devices) that can communicate with each other via communication links 110 (e.g., wireless communication channels), as well as a cluster of cells 126, 130, 132, 134, 136, 138, and 140 that cover a geographic area 101. In Figure 1 In the example shown, the BS 102 and the UE 104 are contained within the respective geographic boundaries of the cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 can include at least one base station operating under its assigned bandwidth to provide sufficient wireless coverage to its intended users.

[0041] For example, the BS 102 can operate under an assigned channel transmission bandwidth to provide sufficient coverage to the UE 104. The BS 102 and the UE 104 can communicate via downlink wireless frames 118 and uplink wireless frames 124, respectively. Each wireless frame 118 / 124 can be further divided into subframes 120 / 127, which can include data symbols 122 / 128. In the present disclosure, the BS 102 and the UE 104 are described herein as non-limiting examples of "communication nodes," which can generally practice the methods disclosed herein. According to various embodiments of the present solution, such communication nodes can be capable of wireless and / or wired communication.

[0042] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) is shown in accordance with some embodiments of the present solution. The system 200 can include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one illustrative embodiment, the system 200 can be used to transmit (e.g., send and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 described above. Figure 1

[0043] ​System 200 typically includes a base station 202 (hereinafter referred to as "BS202") and a user equipment terminal 204 (hereinafter referred to as "UE204"). BS202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with each other as needed via a data communication bus 220. UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with each other as needed via a data communication bus 240. BS202 communicates with UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0044] As will be understood by those skilled in the art, system 200 may also include, in addition to Figure 2 Any number of modules other than those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any actual combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, the various illustrative components, blocks, modules, circuits, and steps are generally described according to their functionality. Whether this functionality is implemented as hardware, firmware, or software can be specific to the application and depends on the design constraints imposed on the system as a whole. Those skilled in the art can implement this functionality appropriately for each specific application, but such implementation decisions should not be construed as limiting the scope of this disclosure.

[0045] According to some embodiments, the UE transceiver 230 can be referred to herein as an "uplink" transceiver 230, which includes radio frequency (RF) transmitters and RF receivers, each including circuitry coupled to an antenna 232. A duplexing switch (not shown) can alternatively couple the uplink transmitter or receiver to the uplink antenna in a time duplexed manner. Similarly, according to some embodiments, the BS transceiver 210 can be referred to herein as a "downlink" transceiver 210, which includes RF transmitters and RF receivers, each including circuitry coupled to an antenna 212. A downlink duplexing switch can alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in a time duplexed manner. The operation of the two transceiver modules 210 and 230 can be coordinated in time such that at the same time the downlink transmitter is coupled to the downlink antenna 212, the uplink receiver circuitry is coupled to the uplink antenna 232, so as to receive transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 can be coordinated in time such that at the same time the uplink transmitter is coupled to the uplink antenna 232, the downlink receiver is coupled to the downlink antenna 212, so as to receive transmissions over the wireless transmission link 250. In some embodiments, there is a tight time synchronization with minimal guard time between changes of duplex direction.

[0046] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and in cooperation with appropriately configured RF antenna arrangements 212 / 232, which can support particular wireless communication protocols and modulation schemes. In some illustrative embodiments, the UE transceiver 230 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that the present disclosure is not necessarily limited to applications for particular standards and related protocols.

[0051] 2、 Systems and methods for DCI retransmission related to beam indication using HARQ-ACK procedure

[0052] In certain systems (e.g., 5G New Radio (NR) and / or other systems), there can be at least two types of downlink control information (DCI) commands. In some embodiments, a new / novel / updated / unified DCI can be used for broadcasting and / or dynamically updating beams (e.g., beam indication). The at least two types of DCI commands can include wireless communication device-specific DCI commands, group common DCI commands, and / or other DCI commands. Wireless communication device-specific DCI commands can be used for scheduling physical downlink shared channel (PDSCH) transmissions, physical uplink shared channel (PUSCH) transmissions, and / or other transmissions. Group common DCI commands can be used for simultaneously configuring / controlling / managing / impacting one or more wireless communication devices (e.g., UEs, terminals, or served nodes) as a group. For example, group common DCI commands can be used for subframe indication (SFI), pre-emption indication, transmission power control (TPC) for physical uplink control channel (PUCCH), TPC for physical uplink shared channel (PUSCH), TPC for sounding reference signal (SRS), and / or other procedures / applications. Group common DCI commands and / or wireless communication device-specific DCI commands (e.g., unscheduled PDSCH / PUSCH transmissions and / or other transmissions) can save / reduce / decrease signaling overhead and / or latency. However, lack of support for retransmission (e.g., in case of reception failure) can result in reduced reliability of the at least two types of DCI commands. In some embodiments, beam-specific DCI can be used / implemented in beam indication for subsequent transmissions. Using beam-specific DCI can result in disruption / interruption / separation of the entire transmission. Misalignment between beams of a wireless communication node (e.g., terrestrial terminal, base station, gNB, eNB, or serving node) and beams of a wireless communication device can result in error / mis-detection of beam-specific DCI, resulting in possible interruption of the entire transmission. Thus, lack of retransmission procedure for DCI can have serious consequences.

[0053] In beam indication, analog beamforming can be used / performed to increase / enhance robustness of high frequency communications in certain systems (e.g., 5G NR). In some embodiments, corresponding analog beamforming indication (e.g., beam indication) can include one or more independent / separate indication procedures / processes for downlink (DL) transmissions and uplink (UL) transmissions.

[0054] In some embodiments, the command can be used to improve / enhance the performance of beam indication in UE high mobility scenarios. The command can be used to simultaneously update / upgrade / adjust / modify / change the beams for DL data / control transmissions (e.g., physical downlink control channel (PDCCH), PDSCH, channel state information reference signal (CSI-RS), and / or other signals / channels) and the beams for UL data / control transmissions (e.g., PUCCH, PUSCH, SRS, and / or other channels / signals).

[0055] The hybrid automatic repeat request acknowledgement (HARQ-ACK) procedure for beam-specific DCI can be used / implemented / design in the common DL / UL beam indication framework to provide reliability / support for DCI retransmission. The HARQ-ACK procedure for beam-specific DCI (e.g., wireless communication device-specific DCI without scheduling PDSCH and / or group common DCI) can support retransmission of unified beam indication for DL / UL data transmission / reception and / or DL / UL control transmission / reception. The HARQ-ACK procedure for beam-specific DCI can face / solve one or more of the following issues / challenges:

[0056] 1) The HARQ-ACK procedure can be divided / classified / into at least two categories. The at least two categories can include a semi-static category, a dynamic category, and / or other categories for the HARQ-ACK procedure. The systems and methods presented herein include / provide one or more methods for carrying / providing / indicating corresponding HARQ-ACK information bits in the at least two categories.

[0057] • In the semi-static category, the HARQ-ACK codebook determination can be based on candidate PDSCH reception (e.g., from the perspective of the wireless communication device). However, the PDSCH transmission (or other transmission) can not be scheduled by the beam-specific DCI. Therefore, the systems and methods presented herein can include a novel / new virtual PDSCH reception (or some other reference transmission) corresponding to the beam-specific DCI.

[0058] • In the dynamic category, the downlink assignment index (DAI) corresponding to the beam-specific DCI can be recommended / used to determine / form the HARQ-ACK codebook. In some embodiments, at least two types of DAI (including counter DAI and / or total DAI) can be used.

[0059] 2) In some embodiments, the method for reporting / specifying / indicating the HARQ-ACK information bits can be used to support the unified beam indication for DL / UL data transmission / reception and / or DL / UL control transmission / reception.

[0060] The independent procedure of the location, which is part of the codebook. Other types of procedures can be used to multiplex the HARQ-ACK information corresponding to the beam-specific DCI command into the normal HARQ-ACK codebook.

[0061] 3) In some embodiments, a group common DCI command can be used to implement / execute beam indication. The group common DCI command can correspond to / concern a group of one or more wireless communication devices. One or more wireless communication devices in the group of wireless communication devices can dynamically join and / or leave the group. For example, mechanisms for dynamic configuration of wireless communication devices (e.g., UEs with parameters corresponding to group common DCI) can be considered / used.

[0062] In certain systems, the use of high frequency resources can induce / produce / cause considerable propagation loss. As a result, wide and / or ultra-wide spectrum resources can pose / introduce / cause significant challenges (e.g., due to propagation loss). Referring now to Figure 3 FIG. 3 depicts an example method 300 for beam-based UL and / or DL transmission. Figure 3 The beams 302 and 304 of FIG. 3 can indicate / specify / represent selected / identified transmit (Tx) beams and / or receive (Rx) beams for transmission. In some embodiments, certain techniques / art can enable / cause beam alignment and / or obtain / cause sufficient antenna gain. For example, using large-scale multiple-input multiple-output (MIMO) (e.g., one node with up to 1024 antenna elements) antenna arrays and / or beamforming training techniques can enable beam alignment and / or sufficient antenna gain. In some embodiments, analog phase shifters can be used to implement / enable millimeter wave beamforming. Using analog phase shifters can result in low-cost implementations, while having the advantages of using antenna arrays. If analog phase shifters are used (e.g., to implement millimeter wave beamforming), the number of controllable phases can be limited / constrained / restricted. In some embodiments, the use of analog phase shifters can impose / cause one or more constant modulus constraints on the analog phase shifters. Given a set of one or more pre-specified beam patterns, the purpose / goal of beamforming (BF) training based on variable phase shifting can correspond to identifying / determining an optimal beam pattern for subsequent data transmission. The identified beam pattern can be applied to one or more scenarios with one transmit-receive point (TRP) and / or one panel (e.g., a UE with one panel).

[0063] In some embodiments, a beam state can correspond to / refer to a quasi co-located (QCL) state, a transmission configuration indicator (TCI) state, a spatial relation state (or spatial relation information state), a reference signal (RS), a spatial filter, and / or a precoding.

[0074] A. Embodiment 1: General description of HARQ-ACK procedure for beam specific DCI

[0075] In some embodiments, a UL resource (e.g., a PUCCH resource and / or other resource) can carry / include / provide / specify / indicate HARQ-ACK information. The HARQ-ACK information can be included / specified / located in a corresponding location in a HARQ-ACK codebook and / or used for ACK / NACK determination. A DCI command with TCI indication can be used to specify / indicate / provide / identify at least one UL resource. In some embodiments, the DCI command can be used to update / modify / adjust at least one UL and / or DL beam. The reporting of HARQ-ACK information (or other information) can be used to determine / configure applicable timing for updating / scheduling at least one UL / DL beam.

[0076] In some embodiments, a DCI can be associated / correlated / linked with a PUCCH resource (and / or other resource). The PUCCH resource can carry / include / provide / specify HARQ-ACK information.

[0077] • Higher layer signaling / commands, such as radio resource control (RRC) signaling and / or medium access control control element (MAC-CE) signaling, can be used to configure / determine / indicate one or more PUCCH resources for a DCI.

[0078] • In some embodiments, a DCI transmission can carry / include / specify / provide a PUCCH resource indicator (PRI) and / or other indicator. The PRI (or other indicator) can indicate / specify / identify the one or more PUCCH resources.

[0079] • In some embodiments, the one or more PUCCH resources can be determined according to a set of PUCCH resources for a number of HARQ-ACK information bits (e.g., a number of HARQ-ACK message bits). UCI The one or more PUCCH resources can be determined according to at least one PRI. As an example, a last DCI of one or more DCIs corresponding to a same slot (or other time instance) for a PUCCH transmission can include / carry / specify the PRI.

[0080] • A parameter can be used to determine / configure a time offset between a PUCCH transmission and a DCI. The parameter can be configured / determined according to a capability of a wireless communication device, a predefined / predetermined configuration, RRC signaling, MAC-CE signaling, another DCI, and / or other configuration / signaling / information.

[0081] ■In some embodiments, the parameter can indicate / specify / provide an offset from / to a time unit / location of the DCI transmission (e.g., relative to the location of the DCI transmission) or a number / total amount of available UL slots (or other time instances).

[0082] • For example, the sequence of slots can include at least five slots (e.g., slot D#0, slot D#1, slot D#2, slot D#3, and / or slot D#4). In some embodiments, the DCI can be received / obtained in the first slot (e.g., slot D#0) of the sequence of slots. The parameter used to determine the time offset (e.g., to determine the number of available UL slots) can correspond to / indicate one slot. If the first available UL slot corresponds to the fourth slot (or other slot) of the sequence of slots (e.g., U#3), the fourth slot can carry / include / provide the HARQ-ACK information.

[0083] ■In some embodiments, the PUCCH transmission in the first UL time unit after the time instance / unit of the DCI transmission can carry / include / provide / specify the HARQ-ACK information.

[0084] In some embodiments, the location of the HARQ-ACK information in the HARQ codebook can correspond to the first bit, the last bit, and / or a predefined bit of the HARQ-ACK codebook. In some embodiments, the HARQ-ACK information bit for the DCI can be located prior / to / before or after / after / following the HARQ-ACK codebook for the associated / relevant PDSCH reception and / or release. In embodiments discussed herein, Embodiment 2 can include / provide / specify one or more procedures / systems / operations for determining the location of the HARQ-ACK information (e.g., corresponding to the DCI) in the HARQ codebook in a semi-static procedure. Embodiment 3 can include one or more procedures / systems / operations for determining the location of the HARQ-ACK information (e.g., corresponding to the DCI) in the HARQ codebook in a dynamic procedure.

[0085] In some embodiments, a wireless communication device can fail to detect / identify the DCI. In response to failing to detect the DCI, the wireless communication device can generate / create a non-acknowledgement (NACK) value for the HARQ-ACK information. The NACK value can be scheduled / positioned at a location relative to a transport block, a virtual PDSCH, one or more code block groups (CBGs), and / or other applications. In some embodiments, the HARQ-ACK information bits can correspond to PDSCH receptions (e.g., successful PDSCH receptions and / or unsuccessful PDSCH receptions). The PDSCH can include transport blocks of the PDSCH and / or CBGs of the PDSCH. A transport block can include one or more CBGs.

[0086] • In some embodiments, the wireless communication device can receive / obtain one or more candidate PDSCHs. If the wireless communication device (successfully) receives the one or more candidate PDSCHs or a virtual PDSCH (corresponding to the DCI beam state information), the wireless communication device can ignore / disregard / neglect the NACK value.

[0087] In some embodiments, the wireless communication device can detect / identify the DCI through one or more PDSCH receptions. In response to detecting the DCI, the wireless communication device can generate / create an acknowledgement (ACK) value for the HARQ-ACK information. The ACK value can be scheduled / positioned at a location relative to a transport block, a virtual PDSCH, one or more code block groups (CBGs), and / or other applications. In some embodiments, the DCI can be used to indicate / specify at least one TCI state (e.g., a beam indication). The one or more TCI states can be applied to DL and / or UL signals at a time location (e.g., a slot and / or other time instance) that is Q time units after transmitting the HARQ-ACK information. In some embodiments, the one or more TCI states can be applied to DL and / or UL signals at a time location corresponding to a slot (or other time instance) that is Q time units after a time instance corresponding to the HARQ-ACK transmission.

[0088] • A value of Q can be determined / configured according to a capability of the wireless communication device, a pre-defined configuration, RRC signaling, MAC-CE signaling, another DCI transmission, and / or other configuration / signaling / information.

[0089] Referring now to Figure 4 , an example method 400 is depicted for independent HARQ-ACK procedures using DCI with TCI indication. At a slot n-K xIn (or other time instances), the wireless communication device can receive / acquire a DCI indicating / specifying the TCI. The TCI can be used to update / regenerate at least one beam of one or more DL / UL signals. The corresponding HARQ-ACK information bits can be reported / specified / indicated in time slot n (or other time instances). x The value of K can be configured / determined based on the RRC parameter (or other parameters). In some embodiments, K x It can have the same characteristics as the Kth. x The value corresponds to an available UL timeslot (or other time instance). The indicated TCI can be applied to DL and / or UL signals, where the indicated TCI is K after the transmission of HARQ-ACK information. y A time slot is applied / used. HARQ-ACK information for DCI commands can be added / attached before / before the normal / nominal HARQ-ACK of the PDSCH (or other signals). In some embodiments, the wireless communication node (e.g., gNB) may fail to receive / acquire the PUCCH, and / or the value of the HARQ-ACK information may correspond to NACK. If the wireless communication node fails to receive the PUCCH and / or the HARQ-ACK information has a NACK value, the wireless communication node can use time slot n+K. y The DCI is retransmitted / retransmitted using a previous / prior time instance (e.g., a time slot). In some embodiments, the wireless communication node may attempt to retransmit / retransmit the DCI using an older / deprecated and / or newer DL Tx beam.

[0090] In some embodiments, the DCI can correspond to a DCI used to schedule a PDSCH (e.g., DCI format 1 0, DCI format 1 1, and / or DCI format 1 2) and / or a DCI used to schedule a PUSCH (e.g., DCI format 0 0, DCI format 0 1, and / or DCI format 0 2). In some embodiments, a HARQ process number field of the DCI can be set to a particular value, and / or a redundancy version (RV) field of the DCI can be set to a particular value. In some embodiments, a modulation and coding scheme (MCS) field of the DCI can be set to a particular value, and / or a frequency domain resource allocation field of the DCI can be set to a particular value. In some embodiments, an uplink and / or downlink shared channel indicator field of the DCI can be set to a particular value. Further, the particular value can include or correspond to a value of “0”, “1”, all “0”, all “1”, and / or other values. Further, if the uplink / downlink shared channel indicator field is set to the particular value, the uplink / downlink shared channel can be prevented from being transmitted and / or received, and / or the DCI can not schedule the uplink / downlink shared channel.

[0091] B. Embodiment 2: Semi-static procedure for reporting HARQ-ACK information bits

[0092] A location of the HARQ-ACK information in the HARQ-ACK codebook can be determined / calculated in a semi-static procedure (e.g., a mode of the HARQ-ACK codebook is configured as “semi-static”). In some embodiments, the HARQ-ACK information can correspond to a DCI indicating / specifying / identifying one or more TCI states. The DCI can be associated / related / linked with at least one parameter. The location of the HARQ-ACK information / bits (in the HARQ-ACK codebook) can be determined according to the at least one parameter. The at least one parameter can include at least one of the following parameters:

[0093] • The at least one parameter can include a time offset (e.g., a slot offset or other offset). The time offset can correspond to / refer to a time offset from a DL data channel to a corresponding HARQ-ACK (e.g., dl-DataToUL-ACK). The time offset can be carried / included / specified by the DCI, and / or configured / determined by a MAC-CE command, an RRC command, and / or other command.

[0094] o A set of time offsets can include / indicate / specify time offsets. The set of time offsets can include one or more time offsets. The set of time offsets can correspond to / refer to a set of time offsets from a DL data channel to a corresponding HARQ-ACK (e.g., dl-DataToUL-ACK).

[0095] o A set of default time offsets can include time offsets. The set of default time offsets can include one or more default time offsets. The set of default time offsets can correspond to / refer to a set of default time offsets from a DL data channel to a corresponding HARQ-ACK (e.g., {1, 2, 3, 4, 5, 6, 7, 8}). In some embodiments, the monitored DCI format can correspond to DCI format 1_0 (or other DCI format). In some embodiments, the set of time offsets from a DL data channel to a corresponding HARQ-ACK can not be configured. The set of default time offsets can provide / include / specify time offsets if the DCI format is not DCI format 1_0 and / or the set of time offsets is not configured.

[0096] o In some embodiments, a time offset can indicate / provide / specify a number / total amount of available UL slots (or other time instances) relative to a location (e.g., time unit) of the DCI.

[0097] • The at least one parameter can include a time domain resource parameter (or other parameter) of a DL signal (or other signal). In some embodiments, the DCI (or other information) can carry / include / provide / specify the time domain resource parameter. High layer signaling (e.g., MAC-CE signaling, RRC signaling, and / or other type of signaling) can be used to determine / configure the time domain resource parameter.

[0098] o A set of time domain resource parameters for a DL signal (e.g., PDSCH and / or other signal) can include / specify / indicate / carry the time domain resource parameter. For example, the time domain resource parameter can include or correspond to PDSCH-TimeDomainResourceAllocationList.

[0099] o In some embodiments, reception of a virtual PDSCH (or other DL signal / channel or reference channel / transmission) can be associated / correlated with the time domain resource parameter and / or the same slot (or other time instance) as the DCI. The virtual PDSCH can be used to determine a location of HARQ-ACK information in a HARQ-ACK codebook.

[0100] • The at least one parameter can include a subcarrier spacing for DL and / or a subcarrier spacing for UL.

[0101] • The at least one parameter can include one or more parameters for a DL and / or UL pattern (e.g., TDD-UL-DL-ConfigurationCommon, TDD-UL-DL-ConfigDedicated, and / or other parameter for a DL / UL pattern).

[0102] In some embodiments, a slot (or other duration / time unit) offset between the DCI and the time domain resources (e.g., associated with the time domain resource parameter) can have a zero value (or other value). In some embodiments, a slot offset between the DCI and the DL channel reception / release can have a zero value (or other value). In some embodiments, the reception of the virtual PDSCH can be associated / related / linked with the same slot (or other time instance) as the DCI. In some embodiments, a location of the HARQ-ACK information in the HARQ-ACK codebook can correspond to a location of a corresponding DL signal reception (e.g., PDSCH reception and / or other DL signal reception) determined by the time domain resource parameter (or other parameter).

[0103] In one example, the semi-static procedure can include HARQ-ACK information corresponding to DCI indicating / specifying / identifying one or more TCI states. In the semi-static procedure, the wireless communication device can be configured with a PUCCH resource ID and / or a PUCCH resource indication. The wireless communication device can be configured with a time offset corresponding to a time offset from a DL data (e.g., a DL data channel) to an UL-ACK. The wireless communication device can select / determine / identify the time offset using the RRC parameter PDSCH-TimeDomainResourceAllocationList (or other parameter).

[0104] Referring now to Figure 5 , an example configuration 500 of a DCI format for unified TCI indication in a semi-static HARQ-ACK procedure is depicted. In example configuration (a), the DCI can include / include one or more TCI fields. Each of the one or more TCI fields can correspond to at least one wireless communication device (e.g., a type of group common DCI). For example, a first TCI field can correspond to UE #0, while a second TCI field can correspond to UE #n-1. In some embodiments, a time offset from DL data to HARQ-ACK (e.g., PDSCH to HARQ feedback timing), a PUCCH resource, a radio network temporary identifier (RNTI), and / or a starting bit can be configured / determined by RRC signaling, MAC-CE signaling, and / or other types of signaling.

[0105] In example configuration (b), the DCI can include / contain one or more groups (e.g., one type of group-common DCI). Each of the one or more groups can correspond to at least one wireless communication device (e.g., UE). In some embodiments, each of the one or more groups can include / indicate / carry a PDSCH-to-HARQ feedback timing indicator, a PRI, a TCI field, and / or other indicator / field. For example, a first group including a PDSCH-to-HARQ feedback timing indicator, a PRI field, and / or a TCI field can correspond to a first wireless communication device (e.g., UE#0 and / or other UE). In some embodiments, a PUCCH resource associated / related to HARQ-ACK can be determined according to a PRI (e.g., a PRI of the DCI). A high layer signaling (e.g., RRC signaling, MAC-CE signaling, and / or other type of signaling) can configure / determine a RNTI and / or a starting bit.

[0106] In example configuration (c), the DCI can include a wireless communication device ID (or UE ID) field, a PDSCH-to-HARQ feedback timing indicator, a PRI, at least one TCI field, and / or other field / indicator (e.g., wireless communication device-specific DCI without PDSCH scheduling). A UE ID can be configured / determined using RRC command, MAC-CE command, and / or other command / signaling. The UE ID field can indicate / specify / identify at least one wireless communication device in a group of one or more wireless communication devices. The wireless communication devices of the group can have the same field for DCI format and / or RNTI.

[0107] Referring now to Figure 6 , an example method 600 is depicted for a semi-static HARQ-ACK procedure corresponding to DCI with TCI indication. In some embodiments, a location of HARQ-ACK information in a HARQ-ACK codebook can be the same location of a corresponding DL signal reception (e.g., PDSCH reception) determined using a time domain resource parameter. In one example, a wireless communication device can receive a DCI in a slot n-K x(or other time instance). The DCI can indicate a TCI for updating at least one beam for one or more UL / DL signals. A corresponding PDSCH reception (e.g., virtual PDSCH or other reference channel reception / determination) can be determined according to time domain resource parameters (or other parameters) of the PDSCH (e.g., time domain resource allocation indication and / or time domain resource allocation (TDRA) field). HARQ-ACK information bits / positions (and / or other information) corresponding to the DCI can be reported / indicated / specified in slot n (or other time instance). A time offset (e.g., 3 slots and / or other time instances) from the DL data to the UL-ACK can be configured by a RRC parameter (or other parameter). A position of the corresponding HARQ-ACK information in a HARQ-ACK codebook can be determined based on the reception of the virtual PDSCH (or other channel / signal). Thus, the HARQ-ACK information corresponding to the DCI can be multiplexed with other HARQ-ACK information for the reception of the PDSCH. In some embodiments, the indicated TCI can be applied to one or more UL and / or DL signals after the transmission of the HARQ-ACK information. y slot (or other time instance).

[0108] C. Embodiment 3: Dynamic procedure for reporting HARQ-ACK information bits

[0109] A position of the HARQ-ACK information in a HARQ-ACK codebook can be determined / computed in a dynamic procedure (e.g., a mode of the HARQ-ACK codebook is configured as “dynamic”). In some embodiments, the HARQ-ACK information can correspond to a DCI (or other information). The DCI can be associated / related / linked with at least one parameter. A position (e.g., bit position) of the HARQ-ACK information can be determined according to the at least one parameter. The at least one parameter can include / specify a time offset (or other offset) from the DCI command and / or associated PDCCH to the HARQ-ACK information. The at least one parameter can include / indicate a time offset from the DCI command and / or associated PDCCH to a PDSCH. The at least one parameter can include / indicate a time offset from the PDSCH to the HARQ-ACK information. In some embodiments, one or more time offsets can be used to determine / configure a time unit for the HARQ-ACK information transmission.

[0110] In some embodiments, the at least one parameter can include a PDCCH (or other channel / signal) monitoring occasion and / or a DAI parameter. The DAI parameter can include at least one of a counter DAI and / or a total DAI. The counter / total DAI can be used to check / verify / confirm / validate a miss of a DCI in a PDCCH monitoring occasion.

[0111] • For determining a HARQ-ACK codebook, the DAI parameter can be associated / related / linked with a same control resource set (CORESET) pool ID and / or a same set of one or more DCI formats.

[0112] o In some embodiments, the counter and / or the counter DAI for bits of HARQ-ACK information can be format-specific. One or more distinct / different sets of DCI formats can correspond to different HARQ-ACK codebook determinations. For example, a first set can include DCI format 1 0, DCI format 1 1, and / or DCI format 1 2. Another set can include DCI formats indicating one or more TCI states.

[0113] • The counter DAI can indicate / specify a cumulative number of {service cell, PDCCH} pairs up to a current serving cell and / or a current monitoring occasion. The counter DAI can be indexed / ordered in an ascending order (or other order) among serving cell indexes for a same PDCCH monitoring occasion. The counter DAI can be indexed / ordered in an ascending order (or other order) on PDCCH monitoring occasion indexes.

[0114] o In some embodiments, the PDCCH monitoring occasions can be ordered / classified in an ascending order (or other order) of a starting time of a search space set. The search space set can be associated / related / linked with the PDCCH monitoring occasion.

[0115] • The total DAI can indicate / provide / specify a total number of {service cell, PDCCH} pairs up to a current monitoring occasion. The total DAI can be updated / modified / adjusted from one PDCCH monitoring occasion to another PDCCH monitoring occasion.

[0116] o In some embodiments, the total DAI for DCIs in a PDCCH monitoring occasion can be the same.

[0117] In some embodiments, the DCI can carry / include / specify / indicate a value of a counter DAI. A counter for bits of HARQ-ACK information can be determined / configured according to the value of the counter DAI. For example, the DCI can include a counter DAI field and / or exclude a total DAI to reduce / save at least 25% (e.g., 35%, 45%, 55%, or other percentage) of DCI signaling overhead. In some embodiments, the value of the counter DAI can be less than / fewer than a value of a total DAI following / after a last / recently monitored occasion. Thus, the value of the counter for bits of HARQ-ACK information can correspond to the value of the counter DAI plus 1 (e.g., a value of the value of the counter DAI + 1 and / or other value). In some embodiments, bits of HARQ-ACK information can be added / appended before or after a HARQ-ACK codebook for the PDSCH.

[0118] In some embodiments, a wireless communication device (e.g., a UE) can be configured to receive / obtain the DCI in slot n-K (or other time instance). The parameter K can correspond to a value of a time offset parameter (e.g., a time offset parameter from PDSCH to HARQ feedback). In some embodiments, the total number of bits of HARQ-ACK information can correspond to the total number of bits of HARQ-ACK information plus 1 (or other value). In some embodiments, corresponding bits of information can be determined / configured according to bits of HARQ-ACK information associated with the DCI. The total number of bits of HARQ-ACK information can be used as a variable / value to count the HARQ-ACK information. One or more bits of HARQ-ACK information (e.g., corresponding bits of information) that are added / appended to the HARQ-ACK information can carry / include / specify HARQ information associated with the DCI. In some embodiments, at least one bit of HARQ-ACK information corresponding to the DCI can be multiplexed with one or more bits of HARQ-ACK information, where the one or more bits of HARQ-ACK information can be transmitted with a same PUCCH / PUSCH and / or a same time unit.

[0119] Reference is now made to Figure 7FIG. 7 depicts example configurations 700 of DCI formats in dynamic HARQ-ACK procedures. In example configuration (a), the DCI can include / contain one or more groups (e.g., a type of group common DCI). Each of the one or more groups can correspond to at least one wireless communication device. Each group can include / provide / specify a PDSCH-to-HARQ feedback timing indicator (e.g., an offset indicator), a counter DAI field, a TCI field, and / or other indicators / fields / information. For example, a first group including a PDSCH-to-HARQ feedback timing indicator, a counter DAI field, and / or a TCI field can correspond to a first wireless communication device (e.g., UE#0 and / or other UEs). Higher layer signaling / commands (e.g., RRC, MAC-CE, and / or other types of signaling / commands) can be used to configure PUCCH resources, RNTIs, starting bits of the wireless communication devices, and / or other information.

[0120] In example configuration (b), the DCI can include at least one counter DAI field, one or more TCI fields, and / or other fields. Each of the one or more TCI fields can correspond to at least one wireless communication device (e.g., a type of group common DCI). For example, a first TCI field can be associated with UE#0 (or other wireless communication devices), while a second TCI field can be associated with UE#1 (or other wireless communication devices). In some embodiments, one or more wireless communication devices (e.g., all wireless communication devices) can share the same value of the counter DAI field. The counter DAI used to determine the HARQ-ACK codebook can be associated / correlated with the same DCI format. In example configuration (c), the DCI can include at least one counter DAI field, at least one total DAI field, at least one TCI field, and / or other fields. At least one of the fields of the DCI can correspond to at least one wireless communication device (e.g., a type of wireless communication device-specific DCI without PDSCH scheduling).

[0121] Reference is now made to Figure 8, depicts an example method 800 for a dynamic HARQ-ACK procedure, which corresponds to a beam-specific DCI with TCI indication. In some embodiments, the HARQ-ACK information can correspond to a DCI (e.g., a beam-specific DCI with TCI indication) that indicates one or more TCI states. The HARQ-ACK codebook (or position) for the HARQ-ACK information and / or the DCI for scheduling at least one PDSCH (or other channel / signal) can be determined / configured according to a counter DAI field. Certain DCI formats (e.g., DCI format 1 1 and / or DCI format 1 2) can provide / indicate / specify a total DAI value. The total DAI can be specific / different / specific to a monitored occasion (MO). For example, one or more DCIs can share the same total DAI in one MO.

[0122] D. Embodiment 4: Flexible method for configuring group common DCI command

[0123] In some embodiments, one or more wireless communication devices can have one or more same / similar channel properties. For example, one or more wireless communication devices in a high-speed train (or other environment / location) can have similar channel properties. If one or more wireless communication devices have the same / similar properties, a group common DCI command (or other command) can be used to indicate / specify / provide one or more TCI states (e.g., TCI indication). Using a group common DCI command to indicate one or more TCI states can save / reduce / decrease signaling overhead and / or latency, e.g., at least 25% (e.g., 35%, 45%, 55%, or other percentage).

[0124] Now referring to Figure 9 , depicts an example configuration 900 of a group common DCI command for TCI state indication. In some embodiments, a wireless communication device can configure an RNTI (or other indicator). The RNTI can be used to scramble the group common DCI command. For example, a cyclic redundancy check (CRC) can be used to scramble the DCI format with the RNTI. A parameter corresponding to a starting bit command and / or a number of indicated beam states can be used / configured to determine a field of the group common DCI. The field of the group common DCI can correspond to a field that carries / provides / specifies one or more indicated beam states. The one or more beam states can be obtained from a starting position of the DCI, which is determined by the starting bit.

[0125] In some embodiments, MAC-CE signaling (or other types of signaling, e.g., RRC signaling) can be used to configure / reconfigure one or more parameters corresponding to the DCI (e.g., group common DCI command). The one or more parameters can be configured / reconfigured (e.g., using MAC-CE signaling) to support one or more methods of configuring PDCCH resources for monitoring the group common DCI command. The one or more parameters can include a specific RNTI, parameters of a starting bit command, a number of indicated beam states, a type of HARQ-ACK process (e.g., semi-static and / or dynamic) corresponding to the DCI, support of DAI / total DAI, one or more CORESETs associated with the DCI, one or more search space sets associated with the DCI, a CORESET pool ID, an ID of the wireless communication device, a panel of the wireless communication device, and / or an antenna group of the wireless communication device.

[0126] Reference is now made to Figure 10 FIG. 10 depicts an example scenario 1000 with one or more groups of wireless communication devices corresponding to group common DCI. For example, a scenario with one or more groups of wireless communication devices corresponding to group common DCI can be relevant / applicable to example embodiments with one or more wireless communication devices (e.g., UE1, UE2, UE3, UE4, and / or UE5) in a vehicle (e.g., a bus and / or other vehicle). A wireless communication node (e.g., gNB) can group / classify / arrange one or more wireless communication devices of the bus in the same group with similar beam switching behavior. The group common DCI for each wireless communication device of the bus can be associated with certain resources according to a MAC-CE command (or other command). The wireless communication node can attempt to jointly / update / modify / adjust / change one or more beams of the wireless communication devices of the vehicle (or other group) at the same time instance. For example, the beams corresponding to {UE3, UE4, UE5} can be updated / modified / changed from a first beam to a second beam at the same time instance. However, the beams corresponding to {UE1, UE2} can be left as the second beam. If a wireless communication device leaves the bus (or other vehicle), the wireless communication node can recombine / rearrange the wireless communication device with other wireless communication devices (e.g., pedestrians and / or other wireless communication devices). The wireless communication node can recombine the wireless communication devices via a MAC-CE command (or other command / signaling).

[0127] E. Embodiment 5: Signaling capability of wireless communication device and method of enabling HARQ-ACK process

[0128] In some embodiments, a wireless communication device may report / instruct / specify / provide capability signaling to support a HARQ-ACK procedure for a beam-specific DCI. The wireless communication device may report capability signaling to support a beam-specific DCI after accessing the wireless communication network (e.g., by default, a HARQ-ACK procedure corresponding to the DCI may be supported). The wireless communication network may use RRC configuration (or other configurations) to enable / implement one or more functions (e.g., reporting the capabilities of the wireless communication device).

[0129] From the perspective of a wireless communication node (e.g., gNB), one or more of the following aspects / options / scenarios can enable / trigger the HARQ-ACK process for DCI:

[0130] ●Option / Case 0: SRS, PUSCH and / or PUCCH do not need to be configured with spatial relationship information.

[0131] ●Option / Case 1: SRS, PUSCH and / or PUCCH may not be configured with UL power control parameters (or other parameters).

[0132] In some embodiments, the SRS, PUSCH, and / or PUCCH may not be configured with parameters and / or other parameters of the path loss reference signal (PL-RS).

[0133] ○ SRS associated with / related to PUSCH do not need to be configured with PL-RS parameters (and / or other parameters).

[0134] ○ In some embodiments, the SRS used for non-codebook and / or codebook transmission may not be configured with PL-RS parameters (and / or other parameters).

[0135] ● Option / Scenario 3: Novel / new RRC signaling (or other types of signaling) can be used to enable / trigger one or more functions.

[0136] In some embodiments, one or more high-level parameters such as enableBeamSpecificDCI and / or enableHARQ-ACKforBeamSpecificDCI can be enabled.

[0137] F. Methods for DCI retransmission related to beam indication using the HARQ-ACK procedure

Figures 1-10Any of the components and devices described in the detailed description can be implemented. Generally, the method 1100 can include receiving DCI (1152). The method 1100 can include determining a location of HARQ-ACK information (1154). The method 1100 can include transmitting a PUCCH transmission (1156).

[0139] Referring now to operation (1152), and in some embodiments, a wireless communication device (e.g., UE) can receive / obtain DCI from a wireless communication node (e.g., BS / gNB). The wireless communication node can transmit / broadcast / communicate the DCI to the wireless communication device.

The wireless communication device can generate the ACK value in response to successful detection / identification / reception of the DCI (or other information). The wireless communication device can detect / identify / receive the DCI via at least one of one or more PDCCH receptions.

[0140] Referring now to operation (1154), and in some embodiments, the wireless communication device can determine / configure a location / placement of HARQ-ACK information for a process associated with the DCI (or other information). The wireless communication device can determine a location of the HARQ-ACK information in a HARQ-ACK codebook. In some embodiments, the wireless communication device can determine a first PUCCH (or other channel) resource. In some embodiments, the location (e.g., bit location) of the HARQ-ACK information in the HARQ-ACK codebook can correspond to / indicate a first bit, a last bit, a predefined bit, and / or other location of the HARQ-ACK codebook. In some embodiments, the HARQ-ACK information can be located before or after the HARQ-ACK codebook. The HARQ-ACK codebook can refer to / correspond to a HARQ-ACK codebook for an associated / relevant / corresponding PDSCH reception, PDSCH release, and / or other channel reception / release. In some embodiments, the process (e.g., a HARQ-ACK process for beam-specific DCI and / or other process) can include a reference channel determination (e.g., a virtual PDSCH), a DL channel reception, a DCI reception, a PDCCH reception, and / or other channel / signal / information reception. In some embodiments, the process can include a DL channel release and / or a beam state indication.

[0141] In some embodiments, one or more types of higher layer signaling / commands can be used to configure / determine the first PUCCH resource (or other resource) for the procedure. For example, the first PUCCH resource can be configured using RRC signaling, MAC-CE signaling, and / or other types of signaling / commands. In some embodiments, a PRI (and / or other indicator / information) can be used to indicate / provide / specify the first PUCCH resource (or other resource). The DCI (or other information) can carry / include / provide the PRI. In some embodiments, the second PUCCH resource (or other resource) can carry / include / specify the HARQ-ACK codebook and / or other information. The wireless communication device can determine / identify the second PUCCH resource from a set of PUCCH resources, where the set of PUCCH resources can include one or more PUCCH resources.

The set of PUCCH resources can include a candidate resource for PUCCH transmission that carries / includes / specifies one or more HARQ-ACK information.

[0142] Now referring to operation (1156), and in some embodiments, the wireless communication device can send / transmit / broadcast the PUCCH transmission (or other transmission) to the wireless communication node. The wireless communication node can receive / obtain the PUCCH transmission (or other transmission) from the wireless communication device. The PUCCH transmission can carry / include / provide / indicate / specify the HARQ-ACK information (or other information). In some embodiments, the time offset can refer to / correspond to a time offset between the DCI and the PUCCH transmission. The time offset can be determined / configured according to at least a first parameter. The first parameter can be configured according to / using / based on a predefined configuration, a capability of the wireless communication device, RRC signaling, MAC-CE signaling, another DCI, and / or other signaling / configuration / capability / information. The first parameter can indicate / provide a number / total amount of available UL time units (e.g., slots and / or other time instances) relative / to according to the time unit (or other information) of the DCI. In some embodiments, a first uplink time unit (e.g., slot and / or other time unit / duration) can include the PUCCH transmission (and / or other transmission). The first uplink time unit can correspond to a first uplink time unit after / following the time unit / instance of the DCI (or other information).

[0143] In some embodiments, a procedure associated with / related to a DCI can trigger / cause an indication of a beam state in the DCI. If the procedure triggers / causes the indication of the beam state in the DCI, the beam state can be applied to at least one DL and / or UL signal. The DL and / or UL signal can correspond to a DL and / or UL signal Q time units (e.g., slots and / or other time instances) after / following a HARQ-ACK information transmission. In some embodiments, Q can be determined / configured according to a predefined configuration, a capability of a wireless communication device, RRC signaling, MAC-CE signaling, another DCI, and / or other types of signaling / capability / configuration / information. In some embodiments, a mode of a HARQ-ACK codebook can be configured to be “semi-static.” If the mode of the HARQ-ACK codebook is configured to be “semi-static,” a HARQ-ACK information can be determined according to one or more parameters / offsets / information. The one or more parameters / offsets / information can include a time offset from a DL data channel (or other data channel) to a corresponding HARQ-ACK, a time domain resource parameter, a subcarrier spacing of the DL, a subcarrier spacing of the UL, and / or at least one parameter of a DL and / or UL pattern (e.g., TDD-UL-DL-ConfigurationCommon, TDD-UL-DL-ConfigDedicated, and / or other parameters of a DL / UL pattern).

[0144] In some embodiments, a time offset from a DL data channel to a corresponding HARQ-ACK can be indicated / specified / provided / selected from a set of time offsets (e.g., a set of one or more time offsets). The set of time offsets can include or correspond to a set of time offsets from a DL data channel to a corresponding HARQ-ACK. The set of time offsets can include or correspond to a set of default time offsets from a DL data channel to a corresponding HARQ-ACK. The set of time offsets can correspond to the set of default time offsets if the DCI has a DCI format 1_0 (or other DCI format) and / or the set of time offsets is not configured. In some embodiments, a time offset can indicate / provide / specify / include a number / total amount of available UL time units (e.g., one or more available UL time units). The number of available UL time units can be related to a time unit (e.g., a slot and / or other time instance) of the DCI. In some embodiments, a set of time domain resource parameters for a DL signal can include / indicate / provide at least one time domain resource parameter. The time domain resource parameter can be selected / identified / indicated from the set of time domain resource parameters. In some embodiments, the procedure can include a reference channel determination (e.g., a virtual PDSCH and / or other reference channel determination). The reference channel can be associated / related to the at least one time domain resource parameter (e.g., PDSCH-TimeDomainResourceAllocationList and / or other parameter). The reference channel can be used to determine a location of HARQ-ACK information in a HARQ-ACK codebook.

[0145] In some embodiments, a reference channel determination can be in a same time unit / instance as the DCI (or other information). In some embodiments, a slot offset between the DCI and the reference channel determination can have a value of zero (or other value). In some embodiments, a slot offset between the DCI and a DL channel reception and / or a slot offset between the DCI and a DL channel release can correspond to zero (or other value). In some embodiments, a location of HARQ-ACK information can be the same as a location of HARQ-ACK information corresponding to the reference channel and / or the DL channel reception determined using the time domain resource parameter.

[0146] In some embodiments, the mode of the HARQ-ACK codebook can be configured as “dynamic”. If the mode of the HARQ-ACK codebook is configured as “dynamic”, the location of the HARQ-ACK information can be determined according to one or more time offsets, monitoring occasions, parameters, and / or other information. In some embodiments, the location of the HARQ-ACK information can be determined according to at least one time offset, such as a time offset from the DCI to the HARQ-ACK information, a time offset from the associated / relevant PDCCH to the HARQ-ACK information, a time offset from the DCI to the PDSCH (or other DL data channel), a time offset from the associated PDCCH to the PDSCH (or other DL data channel), and / or a time offset from the DL data channel (e.g., PDSCH) to the HARQ-ACK information. In some embodiments, the location of the HARQ-ACK information can be determined according to a PDSCH monitoring occasion and / or a DAI parameter. The DAI parameter can include at least one of a counter DAI and / or a total DAI. The counter DAI can indicate / specify the cumulative number of {serving cell, PDCCH} pairs until the current serving cell and / or the current monitoring occasion. The total DAI can indicate / provide / specify the total number of {serving cell, PDCCH} pairs until the current monitoring occasion. In some embodiments, the DAI parameter can be associated / related / linked with a CORESET pool ID, a set of one or more DCI formats, and / or other identifiers / information. In some embodiments, the wireless communication device can determine / configure a counter for the bits of the HARQ-ACK information. The wireless communication device can use the value (or other value) of the counter DAI to determine the counter for the bits of the HARQ-ACK information. The DCI (or other information) can include / carry / provide the value of the counter DAI. For example, the DCI can include the value of the counter DAI to save DCI signaling overhead (e.g., the total DAI can not be provided). In some embodiments, the value of the counter DAI can be less than the value of the total DAI after the last / recently monitored occasion. If the value of the counter DAI is less than the value of the total DAI, the counter for the bits of the HARQ-ACK information can have a value (or other value) corresponding to the value of the counter DAI plus 1.

[0147] In some embodiments, MAC-CE signaling, RRC signaling, and / or other types of signaling can be used to configure and / or reconfigure one or more parameters corresponding to DCI (or other information). A wireless communication device can receive / obtain RRC signaling and / or MAC-CE signaling from a wireless communication node. A wireless communication node can transmit / broadcast / communicate RRC signaling and / or MAC-CE signaling to a wireless communication device. The one or more parameters can include at least one of a particular RNTI, a parameter of a starting bit indication, a number of indicated beam states, and / or a type (e.g., semi-static and / or dynamic) of HARQ-ACK procedure corresponding to the DCI. In some embodiments, the one or more parameters can include support for a DAI and / or a total DAI field in the DCI, one or more CORESET and / or search space sets associated with the DCI, and / or other information. In some embodiments, the one or more parameters can include a CORESET pool ID, an ID of the wireless communication device (e.g., a UE ID), a panel and / or antenna group of the wireless communication device, and / or other information. In some embodiments, a wireless communication device can receive / obtain a configuration of the wireless communication device from a wireless communication node. A wireless communication node can transmit / broadcast / communicate the configuration to a wireless communication device. The configuration of the wireless communication device can correspond to a configuration for supporting a HARQ-ACK procedure for the DCI. The wireless communication node can transmit the configuration in response to SRS, PUCCH, and / or PUSCH not being configured with spatial relation information. The wireless communication device can receive the configuration in response to SRS, PUSCH, and / or PUCCH not being configured with UL power control parameters (or other parameters). The wireless communication device can obtain the configuration in response to particular RRC signaling and / or other types of signaling.

[0148] In some embodiments, the SRS, PUSCH, and / or PUCCH can not be configured with parameters (or other parameters) of a PL-RS. In some embodiments, the SRS associated with the PUSCH can not be configured with parameters of a PL-RS. In some embodiments, the SRS for non-codebook and / or codebook transmission can not be configured with parameters (or other parameters) of a PL-RS. In some embodiments, a HARQ process number field in DCI can be set / configured to a particular value. In some embodiments, a redundancy version (RV) field in DCI can be set / configured to a particular value. In some embodiments, a modulation and coding scheme (MCS) field in DCI can be set / configured to a particular value. In some embodiments, a frequency domain resource allocation field (or other field) in DCI can be set to a particular value. In some embodiments, a UL and / or DL shared channel indicator field (or other field) in DCI can be set to a particular value. In some embodiments, the UL and / or DL shared channel indicator field (or other field) can be set / configured to a particular value. In some embodiments, if the UL and / or DL shared channel indicator field is configured to a particular value, the transmission of the UL and / or DL shared channel can be prevented.
