Patent Description:
The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called <NUM> New Radio (<NUM> NR) as well as a Next Generation Packet Core Network (NG-CN or NGC). The <NUM> NR will have three main components: a <NUM> Access Network (<NUM>-AN), a <NUM> Core Network (5GC), and a User Equipment (UE). In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based, and some being hardware based, so that they could be adapted according to need.

<NPL> and <CIT> are documents of the related art.

The example embodiments disclosed herein are directed to solving the issues relating to one or more of the problems presented in the prior art, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompany drawings. In accordance with various embodiments, example systems, methods, devices and computer program products are disclosed herein. It is understood, however, that these embodiments are presented by way of example and are not limiting, and it will be apparent to those of ordinary skill in the art who read the present disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of this disclosure.

At least one aspect is directed to a system, method, apparatus, or a computer-readable medium. A wireless communication device may receive a downlink control information from a wireless communication node. The wireless communication device may 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 may determine a first physical uplink control (PUCCH) resource. The wireless communication device may transmit a PUCCH transmission that carries the HARQ-ACK information to the wireless communication node.

In some embodiments, the procedure may comprise 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, the first PUCCH resource can be configured for the procedure using a radio resource control (RRC) signaling or a medium access control control element (MAC CE) signaling. In some embodiments, the first PUCCH resource may be indicated by a PUCCH resource indicator (PRI) in the DCI. In some embodiments, the HARQ-ACK codebook may be carried by a second PUCCH resource. In some embodiments, the wireless communication device may determine the second PUCCH resource from a set of PUCCH resources that is associated with a same time unit for PUCCH transmission corresponding to the HARQ-ACK information. In some embodiments, the set of PUCCH resources comprises at least one candidate resource for PUCCH transmission that carries one or more HARQ-ACK information.

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

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

In some embodiments, a mode of the HARQ-ACK codebook may be configured as "semi-static". In some embodiments, the location of the HARQ-ACK information may 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 for downlink, a subcarrier spacing for uplink, or at least one parameter for downlink and uplink patterns. In some embodiments, the time offset may be indicated or selected from a set of time offsets from the downlink data channel to the corresponding HARQ-ACK. In some embodiments, the time offset may be indicated or selected from a set of default time offsets from the downlink data channel to the corresponding HARQ-ACK, if the DCI has DCI format 1_0 or the set of time offsets is not configured. In some embodiments, the time offset may indicate a number of available uplink time units relative to a time unit of the DCI. In some embodiments, the time domain resource parameter may be indicated or selected from a set of time domain resource parameters for a downlink signal. In some embodiments, the procedure may comprise a reference channel determination. In some embodiments, a reference channel may be associated with the time domain resource parameter. In some embodiments, the reference channel may be used for determining the location of the HARQ-ACK information in the HARQ-ACK codebook.

In some embodiments, the reference channel determination may be in a 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 may be zero. In some embodiments, the location of the HARQ-ACK information may be the same as a location of a HARQ-ACK information corresponding to a reference channel or downlink (DL) channel reception determined using the time domain resource parameter. In some embodiments, a mode of the HARQ-ACK codebook may be configured as "dynamic". In some embodiments, the location of the HARQ-ACK information may 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 the associated PDCCH, to a downlink data channel (e.g., PDSCH), a time offset from a downlink data channel (e.g., PDSCH) to the HARQ-ACK information, a PDCCH monitoring occasion, or a downlink assignment index (DAI) parameter.

In some embodiments, the DAI parameter may comprise at least one of a counter DAI and a total DAI. In some embodiments, the DAI parameter may 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 may determine, according to a value of the counter DAI, a counter for bits of the HARQ-ACK information. In some embodiments, the DCI may include the value of the counter DAI. In some embodiments, a value of the counter DAI may be smaller than a value of the total DAI after a last monitored occasion. In some embodiments, the counter for bits of the HARQ-ACK information may have the value of the counter DAI + <NUM>.

In some embodiments, the wireless communication device may receive radio resource control (RRC) signaling or a medium access control control element (MAC CE) from the wireless communication node. In some embodiments, the RRC signaling or MAC CE signaling may configure or reconfigure one or more parameters corresponding to the DCI. In some embodiments, the one or more parameters may comprise at least one of: a specific radio network temporary identifier (RNTI), a parameter of a starting bit indication, a number of indicated beam states, or a type of HARQ-ACK procedure corresponding to the DCI, comprising semi-static or dynamic. In some embodiments, the one or more parameters may comprise at least one of: support of downlink assignment index (DAI) or total DAI field in a 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 may receive a configuration for the wireless communication device to support a HARQ-ACK procedure for the DCI from the wireless communication node. In some embodiments, the wireless communication device may receive the configuration responsive 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 may receive the configuration responsive to the SRS, the PUSCH and the PUCCH not being configured with an uplink power control parameter. In some embodiments, the wireless communication device may receive the configuration responsive to a specific radio resource control (RRC) signaling.

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

In some embodiments, the first PUCCH resource may be indicated by a PUCCH resource indicator (PRI) in the DCI. In some embodiments, the HARQ-ACK codebook may be carried by a second PUCCH resource. In some embodiments, the wireless communication device may determine the second PUCCH resource from a set of PUCCH resources that is associated with a same time unit for PUCCH transmission corresponding to the HARQ-ACK information. In some embodiments, the set of PUCCH resources comprises at least one a candidate resource for PUCCH transmission that carries one or more HARQ-ACK information.

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

In some embodiments, the wireless communication node may transmit radio resource control (RRC) signaling or a medium access control control element (MAC CE) to the wireless communication device. In some embodiments, the RRC signaling or MAC CE signaling may configure or reconfigure one or more parameters corresponding to the DCI. In some embodiments, the one or more parameters may comprise at least one of: a specific radio network temporary identifier (RNTI), a parameter of a starting bit indication, a number of indicated beam states, or a type of HARQ-ACK procedure corresponding to the DCI, comprising semi-static or dynamic.

In some embodiments, the wireless communication node may send the configuration responsive 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 node may send the configuration responsive to the SRS, the PUSCH and the PUCCH not being configured with an uplink power control parameter. In some embodiments, the wireless communication node may send the configuration responsive to a specific radio resource control (RRC) signaling.

The systems and methods presented herein include a hybrid automatic repeat request (HARQ) procedure to support the retransmission of DCI. One or more solutions for semi-static HARQ procedures, dynamic HARQ procedures, and/or independent HARQ procedures are discussed herein. The one or more solutions may include multiplexing HARQ-ACK information corresponding to a beam specific DCI command into a normal/nominal HARQ-ACK codebook. At least one flexible method for configuring a group common DCI command, for instance by using a MAC-CE command, is presented.

<FIG> illustrates a block diagram of an example wireless communication system <NUM> for transmitting and receiving wireless communication signals (e.g., OFDM/OFDMA signals) in accordance with some embodiments of the present solution. The system <NUM> may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, system <NUM> can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment <NUM> of <FIG>, as described above.

In certain systems (e.g., <NUM> new radio (NR) and/or other systems), at least two types of downlink control information (DCI) commands can exist. In some embodiments, a new/novel/updated/unified DCI may be used to broadcast and/or dynamically update a beam (e.g., beam indication). The at least two types of DCI commands may comprise a wireless communication device specific DCI command, a group common DCI command, and/or other DCI commands. The wireless communication device specific DCI command may be used to schedule a physical downlink shared channel (PDSCH) transmission, a physical uplink shared channel (PUSCH) transmission, and/or other transmissions. The group common DCI command may be used to simultaneously configure/control/manage/affect one or more wireless communication devices (e.g., a UE, a terminal, or a served node) as a group. For instance, the group common DCI command may be used for sub-frame indication (SFI), pre-emption indication, transmission power control (TPC) of physical uplink control channel (PUCCH), TPC of physical uplink shared channel (PUSCH), TPC of sounding reference signal (SRS), and/or other processes/applications. The group common DCI command and/or wireless communication device specific DCI command (e.g., without a scheduled PDSCH/PUSCH transmission and/or other transmissions) may save/reduce/decrease signaling overhead and/or latency. However, a lack of support for retransmission (e.g., in case of failed reception) may cause a reduced reliability of the at least two types of DCI commands. In some embodiments, beam specific DCI may be used/implemented in beam indication for a subsequent transmission. Using the beam specific DCI may cause a breakage/interruption/separation of a whole transmission. A misalignment between a beam of a wireless communication node (e.g., a ground terminal, a base station, a gNB, an eNB, or a serving node) and a beam of the wireless communication device may cause a false/missed detection of the beam specific DCI, causing a possible interruption of the whole transmission. Therefore, a lack of retransmission procedures for the DCI may have serious consequences.

In beam indication, analog beam-forming may be used/executed to increase/enhance the robustness of high frequency communications in certain systems (e.g., <NUM> NR). In some embodiments, a corresponding analog beam-forming indication (e.g., beam indication) may include one or more independent/separate indication procedures/processes for downlink (DL) transmissions and uplink (UL) transmissions.

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

A hybrid automatic repeat request acknowledgement (HARQ-ACK) procedure for beam specific DCI may be used/implemented/designed in a common DL/UL beam indication framework to provide reliability/support for DCI retransmissions. The HARQ-ACK procedure for beam specific DCI (e.g., a wireless communication device specific DCI without scheduling PDSCH and/or for a group common DCI) may support the retransmission of unified beam indication of (multiple) DL/UL data transmissions/receptions and/or DL/UL control transmissions/receptions. The HARQ-ACK procedure for beam specific DCI may face/address one or more of the following issues/challenges:.

In certain systems, the use of high frequency resources may induce/produce/cause a considerable propagation loss. Therefore, wide and/or ultra-wide spectrum resources may pose/introduce/cause noticeable challenges (e.g., due to propagation loss). Referring now to <FIG>, depicted is an example approach <NUM> for beam based UL and/or DL transmissions. Beam <NUM> and beam <NUM> of <FIG> may indicate/specify/represent a selected/identified transmit (Tx) beam and/or receive (Rx) beam for transmissions. In some embodiments, certain technologies/techniques may achieve/cause beam alignment and/or obtain/cause sufficient antenna gain. For example, antenna arrays and/or beam-forming training techniques that use massive multiple-input multiple-output (MIMO) (e.g., up to <NUM> antenna elements for one node) may achieve beam alignment and/or sufficient antenna gain. In some embodiments, analog phase shifters may be used to implement/enable mmWave beam-forming. Using analog phase shifters may result in a low cost of implementation with the benefits of using antenna arrays. If analog phase shifters are used (e.g., to implement mmWave beam-forming), the number of controllable phases may be finite/defined/restricted. In some embodiments, the use of analog phase shifters may place/cause one or more constant modulus constraints on the analog phase shifters. Given a set of one or more pre-specified beam patterns, the goal/target of variable-phase-shift-based beamforming (BF) training may correspond to identifying/determining the optimum beam pattern for subsequent data transmissions. The identified beam pattern may apply to one or more scenarios with one transmit receive point (TRP) and/or one panel (e.g., a UE with one panel).

In some embodiments, a beam state may correspond/refer to a quasi co-location (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 pre-coding.

The spatial relation information may be used to specify/indicate/convey/represent a same and/or quasi-co spatial relation between a targeted RS/channel and the one or more reference RSs. In some embodiments, a spatial relation may refer to a beam, a spatial parameter, and/or a spatial domain filter.

In some embodiments, a QCL state may comprise one or more reference RSs and/or one or more corresponding QCL type parameters. The QCL type parameters may include at least one of a Doppler spread, a Doppler shift, a delay spread, an average delay, an average gain, and/or a spatial parameter (e.g., a spatial Rx parameter). In some embodiments, a TCI state may correspond/refer to a QCL state. In some embodiments, a QCL Type D may correspond to a spatial parameter and/or a spatial Rx parameter. In some embodiments, an UL signal may include/comprise a PUCCH, a PUSCH, a SRS, and/or other channels/signals. In some embodiments, a DL signal may include/comprise a PDCCH, a PDSCH, a CSI-RS, and/or other channels/signals.

In some embodiments, a time unit may include a sub-symbol, a symbol, a slot, a sub frame, a frame, a transmission occasion, and/or other time instances. In some embodiments, a power control parameter may include a target power (P0), a path loss RS (e.g., a coupling loss RS), a scaling factor for path loss (e.g., alpha), and/or a closed loop process. In some embodiments, a HARQ-ACK may correspond/refer to a hybrid automatic repeat request (HARQ), an acknowledgement/negative acknowledgement (ACK/NACK), an uplink acknowledgement (UL-ACK), and/or confirmation information for a transmission. In some embodiments, the DCI may correspond/refer to a PDCCH, a TCI indication command, a wireless communication device (e.g., UE) specific DCI, a group common DCI, DCI scheduling PUSCH/PDSCH, and/or DCI without scheduling PUSCH/PDSCH. In the description of the systems and methods presented herein, the term "DCI" may be used to refer to a beam specific DCI and/or a DCI indicating one or more TCI states if there is a lack of a specific/particular description.

In some embodiments, a reference channel determination may correspond/refer to a reference channel release, a reference channel validation, a reference channel reception and/or a reference channel transmission. In some embodiments, a reference channel reception may comprise a reference PDSCH reception and/or a reference PDCCH reception. In some embodiments, a reference channel transmission may comprise a reference PUCCH transmission and/or or a reference PUSCH transmission. In some embodiments, the reference channel may comprise a PDSCH, a PDCCH, a PUCCH, and/or a PUSCH. In some embodiments, the reference channel may correspond/refer to a virtual channel. In some embodiments, release may correspond/refer to deactivation. In some embodiments, validation may correspond/refer to activation and/or assignment.

In some embodiments, the definition of an antenna group may correspond to the perspective of the wireless communication device. In some embodiments, an antenna group may correspond to an antenna port group, panel, and/or wireless communication device (e.g., UE) panel.

In some embodiments, a downlink data channel may correspond/refer to a PDSCH and/or a downlink shared channel (DL-SCH).

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

In some embodiments, the DCI can be associated/related/linked with a PUCCH resource (and/or other resources). The PUCCH resource may carry/include/provide/specify the HARQ-ACK information.

In some embodiments, a location of the HARQ-ACK information in the HARQ codebook may correspond to a first bit, a 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/before or after/following a HARQ-ACK codebook for an associated/related PDSCH reception and/or release. Of the embodiments discussed herein, Embodiment <NUM> may include/provide/specify one or more procedures/systems/operations to determine the location of the HARQ-ACK information (e.g., corresponding to the DCI) in the HARQ-ACK codebook in a semi-static procedure. Embodiment <NUM> may include one or more procedures/systems/operations to determine the location of the HARQ-ACK information (e.g., corresponding to the DCI) in the HARQ-ACK codebook in a dynamic procedure.

In some embodiments, the wireless communication device may fail to detect/identify the DCI. Responsive to failing to detect the DCI, the wireless communication device may generate/create a non-acknowledgement (NACK) value for the HARQ-ACK information. The NACK value may 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, a HARQ-ACK information bit may correspond to a PDSCH reception (e.g., successful PDSCH reception and/or unsuccessful PDSCH reception). The PDSCH may include a transport block of the PDSCH and/or a CBG of the PDSCH. The transport block may comprise one or more CBGs.

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

Referring now to <FIG>, depicted is an example approach <NUM> for an independent HARQ-ACK procedure using DCI with TCI indication. In slot n-Kx (or other time instances), the wireless communication device may receive/obtain a DCI that indicates/specifies a TCI. The TCI may be used to update/regenerate at least one beam of one or more DL/UL signals. The corresponding HARQ-ACK information bit may be reported/specified/indicated in slot n (or other time instances). The value of Kx may be configured/determined according to a RRC parameter (or other parameters). In some embodiments, Kx may have a value corresponding to the Kxth available UL slot (or other time instances). The indicated TCI may be applied to DL and/or UL signals, wherein the indicated TCI is applied/used Ky slots following the transmission of the HARQ-ACK information. The HARQ-ACK information of the DCI command may be added/appended prior to / before a normal/nominal HARQ-ACK for a PDSCH (or other signals). In some embodiments, the wireless communication node (e.g., gNB) may be unable to receive/obtain the PUCCH, and/or the value of 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 value of NACK, the wireless communication node may resend/retransmit the DCI using a time instance (e.g., a time slot) before/prior to slot n+Ky. In some embodiments, the wireless communication node may attempt to use an old/stale and/or an updated DL Tx beam to retransmit/resend the DCI.

In some embodiments, the DCI may correspond to a DCI used for scheduling a PDSCH (e.g., DCI format 1_0, DCI format 1_1, and/or DCI format 1_2) and/or a DCI used for scheduling 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 specific value and/or a redundancy version (RV) field of the DCI may be set to a specific value. In some embodiments, a modulation and coding scheme (MCS) field of the DCI may be set to a specific value and/or a frequency domain resource assignment field of the DCI can set to a specific value. In some embodiments, an uplink and/or downlink shared channel indicator field of the DCI may be set to a specific value. Furthermore, the specific value may include or correspond to the values of "<NUM>", "<NUM>", all "<NUM>", all "<NUM>", and/or other values. Furthermore, if the uplink/downlink shared channel indicator field is set to a specific value, the uplink/downlink shared channel may be precluded from transmission and/or reception, and/or the DCI may not schedule the uplink/downlink shared channel.

The location of the HARQ-ACK information in a HARQ-ACK codebook may be determined/calculated in semi-static procedures (e.g., a mode of the HARQ-ACK codebook is configured as "semi-static"). In some embodiments, the HARQ-ACK information may correspond to a DCI that indicates/specifies/identifies one or more TCI states. The DCI may be associated/related/linked with at least one parameter. The location of the HARQ-ACK information/bit (in a HARQ-ACK codebook) may be determined according to the at least one parameter. The at least one parameter may include at least one of the following parameters:.

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

In one example, a semi-static procedure may include HARQ-ACK information corresponding to a DCI that indicates/specifies/identifies one or more TCI states. In the semi-static procedure, the wireless communication device may be configured with a PUCCH resource ID, and/or PUCCH resource indication. The wireless communication device may be configured with a time offset corresponding to a time offset from DL-data (e.g., DL data channel) to UL-ACK. The wireless communication device may select/determine/identify the time offset using the RRC parameter PDSCH-TimeDomainResourceAllocationList (or other parameters).

Referring now to <FIG>, depicted are example configurations <NUM> of a DCI format for unified TCI indication in a semi-static HARQ-ACK procedure. In the example configuration (a), the DCI may include/comprise one or more TCI fields. Each TCI field of the one or more TCI fields may correspond to at least one wireless communication device (e.g., a type of group common DCI). For example, a first TCI field may correspond to UE#<NUM>, while a second TCI field may correspond to UE#n-<NUM>. 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 may be configured/determined by RRC signaling, MAC-CE signaling, and/or other types of signaling.

In the example configuration (b), the DCI may include/comprise one or more groups (e.g., a type of group common DCI). Each group of the one or more groups may correspond to at least one wireless communication device (e.g., UE). In some embodiments, each group of the one or more groups may include/indicate/carry a PDSCH-to-HARQ feedback timing indicator, a PRI, a TCI field, and/or other indicators/fields. For example, a first group comprising a PDSCH-to-HARQ feedback timing indicator, a PRI field, and/or a TCI field may correspond to a first wireless communication device (e.g., UE#<NUM> and/or other UEs). In some embodiments, the PUCCH resource associated/related with the HARQ-ACK may be determined according to the PRI (e.g., the PRI of the DCI). Higher layer signaling (e.g., RRC signaling, MAC-CE signaling, and/or other types of signaling) may configure/determine the RNTI and/or the starting bit.

In the example configuration (c), the DCI may 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 fields/indicators (e.g., a wireless communication device specific DCI without PDSCH scheduling). The UE ID may be configured/determined using an RRC command, a MAC-CE command, and/or other commands/signaling. The UE ID field can indicate/specify/identify at least one wireless communication device of a group of one or more wireless communication devices. The wireless communication devices of the group may have the same field for the DCI format and/or RNTI.

Referring now to <FIG>, depicted is an example approach <NUM> for a semi-static HARQ-ACK procedure corresponding to a DCI with TCI indication. In some embodiments, the location of the HARQ-ACK information in the HARQ-ACK codebook may be the same location of a corresponding DL signal reception (e.g., PDSCH reception) determined using the time domain resource parameter. In one example, the wireless communication device may receive/obtain the DCI in slot n-Kx (or other time instances). The DCI may indicate a TCI for updating at least one beam of one or more UL/DL signals. The corresponding PDSCH reception (e.g., virtual PDSCH or other reference channel reception/determination) can be determined according to the time domain resource parameter (or other parameters) for PDSCH (e.g., time domain resource allocation indication and/or time domain resource assignment (TDRA) field). The HARQ-ACK information bit/location corresponding to the DCI (and/or other information) may be reported/indicated/specified in slot n (or other time instances). The time offset from DL-Data to UL-ACK (e.g., <NUM> slots and/or other time instances) may be configured by a RRC parameter (or other parameters). The location of the corresponding HARQ-ACK information in the HARQ-ACK codebook may be determined based on the reception of the virtual PDSCH (or other channels/signals). Therefore, the HARQ-ACK information corresponding to the DCI may be multiplexed with other HARQ-ACK information for the reception of the PDSCH. In some embodiments, the indicated TCI may be applied to one or more UL and/or DL signals Ky slots (or other time instances) after the transmission of the HARQ-ACK information.

The location of the HARQ-ACK information in a HARQ-ACK codebook may be determined/calculated in dynamic procedures (e.g., a mode of the HARQ-ACK codebook is configured as "dynamic"). In some embodiments, the HARQ-ACK information may correspond to a DCI (or other information). The DCI may be associated/related/linked with at least one parameter. The location (e.g., bit location) of the HARQ-ACK information may be determined according to the at least one parameter. The at least one parameter may include/specify a time offset (or other offsets) from the DCI command and/or an associated PDCCH to the HARQ-ACK information. The at least one parameter may include/indicate a time offset from the DCI command and/or an associated PDCCH to a PDSCH. The at least one parameter may include/indicate a time offset from a PDSCH to the HARQ-ACK information. In some embodiments, one or more of the time offsets can be used to determine/configure the time unit of the HARQ-ACK information transmission.

In some embodiments, the at least one parameter may include a PDCCH (or other channels/signals) monitoring occasion and/or a DAI parameter. The DAI parameter may comprise at least one of a counter DAI and/or a total DAI. The counter/total DAI can be used to check/verify/validate/verify a missed detection of DCI in a PDCCH monitoring occasion.

In some embodiments, the DCI may carry/include/specify/indicate the value of the counter DAI. A counter for bits of the HARQ-ACK information can be determined/configured according to a value of the counter DAI. For example, the DCI may include the counter DAI field and/or exclude the total DAI to reduce/save DCI signaling overhead by at least <NUM>% (e.g., <NUM>, <NUM>, <NUM>, or other percent). In some embodiments, the value of the counter DAI may be less/smaller than the value of the total DAI following/after a last/recent monitored occasion. Therefore, the value of the counter for bits of the HARQ-ACK information may correspond to the value of the counter DAI plus <NUM> (e.g., value of the counter DAI+<NUM> and/or other values). In some embodiments, the bit of HARQ-ACK information can be added/appended prior to or after the HARQ-ACK codebook for PDSCH.

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

Referring now to <FIG>, depicted are example configurations <NUM> of a DCI format in a dynamic HARQ-ACK procedure. In the example configuration (a), the DCI may include/comprise one or more groups (e.g., a type of group common DCI). Each group of the one or more groups may correspond to at least one wireless communication device. Each group may include/provide/specify a PDSCH-to-HARQ feedback timing indicator (e.g., offset indicator), a counter DAI field, a TCI field, and/or other indicators/fields/information. For example, a first group comprising a PDSCH-to-HARQ feedback timing indicator, a counter DAI field, and/or a TCI field may correspond to a first wireless communication device (e.g., UE#<NUM> 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 a PUCCH resource, a RNTI, a starting bit for a wireless communication device, and/or other information.

In the example configuration (b), the DCI may include at least one counter DAI field, one or more TCI fields, and/or other fields. Each TCI field of the one or more TCI fields may correspond to at least one wireless communication device (e.g., a type of group common DCI). For example, a first TCI field may be associated with UE#<NUM> (or other wireless communication devices), while a second TCI field may be associated with UE#<NUM> (or other wireless communication devices). In some embodiments, one or more wireless communication devices (e.g., all wireless communication devices) may share a same value of the counter DAI field. A counter DAI for determining the HARQ-ACK codebook can be associated/related with a same DCI format. In the example configuration (c), the DCI may include at least one counter DAI field, at least one total DAI field, at last one TCI field, and/or other fields. At least one field of the fields of the DCI may correspond to at least one wireless communication device (e.g., a type of wireless communication device specific DCI without PDSCH scheduling).

Referring now to <FIG>, depicted is an example approach <NUM> for a dynamic HARQ-ACK procedure corresponding to a beam specific DCI with TCI indication. In some embodiments, the HARQ-ACK information may correspond to a DCI that indicates one or more TCI states (e.g., beam specific DCI with TCI indication). The HARQ-ACK codebook (or location) for the HARQ-ACK information and/or a DCI for scheduling at least one PDSCH (or other channels/signals) may 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 the total DAI value. The total DAI may be specific/distinct/particular to a monitored occasion (MO). For example, one or more DCIs may share a same total DAI in a MO.

In some embodiments, one or more wireless communication devices may have one or more same/similar channel properties. For example, one or more wireless communication devices in a high-speed train (or other environments/locations) may have similar channel properties. If one or more wireless communication devices have same/similar properties, a group common DCI command (or other commands) 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 may save/reduce/decrease signaling overhead and/or latency by for instance at least <NUM>% (e.g., <NUM>, <NUM>, <NUM>, or other percent).

Referring now to <FIG>, depicted is an example configuration <NUM> of a group common DCI command for TCI state indication. In some embodiments, a wireless communication device may configure a RNTI (or other indicators). The RNTI may be used to scramble the group common DCI command. For example, a cyclic redundancy check (CRC) may 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 may be used/configured to determine a field of the group common DCI. The field of the group common DCI may correspond to the field carrying/providing/specifying 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.

In some embodiments, MAC-CE signaling (or other types of signaling, such as RRC signaling) can be used to configure/reconfigure one or more parameters corresponding to a DCI (e.g., group common DCI command). The one or more parameters may be configured/reconfigured (e.g., using MAC-CE signaling) to support one or more methods of configuring PDCCH resources for monitoring a group common DCI command. The one or more parameters may include a specific RNTI, a parameter of a starting bit command, a number of indicated beam states, a type of HARQ-ACK procedure corresponding to the DCI (e.g., semi-static and/or dynamic), 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.

Referring now to <FIG>, depicted is an example scenario <NUM> with one or more groups of one or more wireless communication devices corresponding to a group common DCI. For example, a scenario with one or more groups of wireless communication devices corresponding to a group common DCI can be relevant/applicable to an example embodiment 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 vehicles). The wireless communication node (e.g., gNB) may group/classify/arrange one or more wireless communication devices of a bus in a same group with a similar beam switching behavior. The group common DCI of each wireless communication device of a bus can be associated with certain resources according to a MAC-CE command (or other commands). The wireless communication node may attempt to update/modify/adjust/change the beam(s) of the wireless communication devices of a vehicle (or other groups) jointly/together at a same time instance. For example, at a same time instance, a beam corresponding to {UE3, UE4, UE5} may be updated/modified/changed from a first beam to a second beam. However, a beam corresponding to {UE1, UE2} may remain as the second beam. If a wireless communication device leaves the bus (or other vehicles), the wireless communication node may regroup/rearrange the wireless communication device with other wireless communication devices (e.g., pedestrians and/or other wireless communication devices). The wireless communication node may regroup the wireless communication device via a MAC-CE command (or other commands/signaling).

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

From the perspective of the wireless communication node (e.g., gNB), one or more of the following aspects/options/scenarios may enable/trigger the HARQ-ACK procedure for the DCI:.

In some embodiments, the wireless communication device may generate/configure/create a NACK value for the HARQ-ACK information. The wireless communication device may generate the NACK value responsive to a failure to (successfully) detect/identify/receive a DCI (or other information).

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

Referring now to operation (<NUM>), and in some embodiments, the wireless communication device may determine/configure a location/position/placement of HARQ-ACK information for a procedure associated with the DCI (or other information). The wireless communication device may determine the location of HARQ-ACK information in a HARQ-ACK codebook. In some embodiments, the wireless communication device may determine a first PUCCH (or other channels) resource. In some embodiments, the location (e.g. bit location) of the HARQ-ACK information in the HARQ-ACK codebook may correspond/refer to a first bit, a last bit, a predefined bit of the HARQ-ACK codebook, and/or other locations. In some embodiments, the HARQ-ACK information can be located prior to or after a HARQ-ACK codebook. The HARQ-ACK codebook may refer/correspond to a HARQ-ACK codebook for an associated/related/corresponding PDSCH reception, PDSCH release, and/or other channel receptions/releases. In some embodiments, the procedure (e.g., HARQ-ACK procedure for beam specific DCI and/or other procedures) may comprise a reference channel determination (e.g., virtual PDSCH), a DL channel reception, a DCI reception, a PDCCH reception, and/or other channel/signal/information receptions. In some embodiments, the procedure may comprise a DL channel release and/or beam state indication.

In some embodiments, one or more types of higher layer signaling/commands may be used to configure/determine the first PUCCH resource (or other resources) for the procedure. For example, the first PUCCH resource may be configured using RRC signaling, MAC-CE signaling, and/or other types of signaling/commands. In some embodiments, a PRI (and/or other indicators/information) may be used to indicate/provide/specify the first PUCCH resource (or other resources). The DCI (or other information) may carry/include/provide the PRI. In some embodiments, a second PUCCH resource (or other resources) may carry/include/specify the HARQ-ACK codebook and/or other information. The wireless communication device may determine/identify the second PUCCH resource from a set of PUCCH resources, wherein the set of PUCCH resources may comprise one or more PUCCH resources. The set of PUCCH resources may be associated/related/linked with a same time unit/instance for PUCCH transmission corresponding to the HARQ-ACK information. The set of PUCCH resources may comprise a candidate resource for a PUCCH transmission that carries/includes/specifies one or more HARQ-ACK information.

Referring now to operation (<NUM>), and in some embodiments, the wireless communication device may transmit/send/broadcast a PUCCH transmission (or other transmissions) to the wireless communication node. The wireless communication node may receive/obtain the PUCCH transmission (or other transmissions) from the wireless communication device. The PUCCH transmission may carry/include/provide/indicate/specify the HARQ-ACK information (or other information). In some embodiments, a time offset may refer/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 may be configured according/using/based on a predefined configuration, a capability of the wireless communication device, RRC signaling, MAC-CE signaling, another DCI, and/or other signaling/configurations/capabilities/information. The first parameter may indicate/provide a number/amount of available UL time units (e.g., a time slot and/or other time instances) relative/according to a time unit of the DCI (or other information). In some embodiments, a first uplink time unit (e.g., a time slot and/or other time unit/duration) may include the PUCCH transmission (and/or other transmissions). The first uplink time unit may correspond to a first uplink time unit after/following a time unit/instance of the DCI (or other information).

In some embodiments, a procedure associated/related with the DCI may 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 may be applied to at least one DL and/or UL signal. The DL and/or UL signal may correspond to a DL and/or UL signal Q time units (e.g., a time slot and/or other time instances) after/following the HARQ-ACK information transmission. In some embodiments, Q may be determined/configured according to a predefined configuration, a capability of the wireless communication device, RRC signaling, MAC-CE signaling, another DCI, and/or other types of signaling/capabilities/configurations/information. In some embodiments, a mode of the HARQ-ACK codebook may be configured as "semi-static". If a mode of the HARQ-ACK codebook is configured as "semi-static", the HARQ-ACK information may be determined according to one or more parameters/offsets/information. The one or more parameters/offsets/information may 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 for DL, a subcarrier spacing for UL, and/or at least one parameter for DL and/or UL patterns (e.g., TDD-UL-DL-ConfigurationCommon, TDD-UL-DL-ConflgDedicated, and/or other parameters for DL/UL patterns).

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

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

In some embodiments, a mode of the HARQ-ACK codebook may be configured as "dynamic". If the mode of the HARQ-ACK codebook is configured as "dynamic", the location of the HARQ-ACK information may 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 an associated/related PDCCH to the HARQ-ACK information, a time offset from the DCI to a PDSCH (or other DL data channels), a time offset from the associated PDCCH to the PDSCH (or other DL data channels), and/or a time offset from a DL data channel (e.g., PDSCH) to the HARQ-ACK information. In some embodiments, the location of the HARQ-ACK information may be determined according to a PDSCH monitoring occasion and/or a DAI parameter. The DAI parameter may comprise at least one of a counter DAI and/or a total DAI. The counter DAI may indicate/specify the cumulative number of {serving cell, PDCCH} pairs up to a current serving cell and/or a current monitoring occasion.

In some embodiments, the DAI parameter may 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 may determine/configure a counter for bits of the HARQ-ACK information. The wireless communication device may use a value of the counter DAI (or other values) to determine the counter for bits of the HARQ-ACK information. The DCI (or other information) may include/carry/provide the value of the counter DAI. For example, the DCI may include the value of the counter DAI to save DCI signaling overhead (e.g., the total DAI may not be provided). In some embodiments, a value of the counter DAI may be smaller/less than a value of the total DAI after a last/recent monitored occasion. If the value of the counter DAI is less than the value of the total DAI, the counter for bits of the HARQ-ACK information may have a value corresponding to the counter DAI plus one (or other values).

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 the DCI (or other information). The wireless communication device may receive/obtain the RRC signaling and/or MAC-CE signaling from the wireless communication node.

The configuration for the wireless communication device may correspond to a configuration to support a HARQ-ACK procedure for the DCI. The wireless communication node may send the configuration responsive to a SRS, a PUCCH, and/or a PUSCH not being configured with spatial relation information. The wireless communication device may receive the configuration responsive to the SRS, the PUSCH, and/or the PUCCH not being configured with an UL power control parameter (or other parameters). The wireless communication device may obtain the configuration responsive to a specific RRC signaling and/or other types of signaling.

In some embodiments, the SRS, the PUSCH, and/or the PUCCH may not be configured with a parameter of PL-RS (or other parameters). In some embodiments, the SRS associated with the PUSCH may not be configured with the parameter of PL-RS. In some embodiments, the SRS for non-codebook and/or codebook transmission, may not be configured with the parameter of PL-RS (or other parameters). In some embodiments, a HARQ process number field in the DCI may be set/configured to a specific value. In some embodiments, a redundancy version (RV) field in the DCI may be set/configured to a specific value. In some embodiments, a modulation and coding scheme (MCS) field in the DCI may be set/configured to a specific value.
