Abstract: A method for wireless communication includes: receiving, at a base station: (1) a capability report for each of a plurality of antenna panels of a first user device; and (2) an initial antenna panel index for the first user device; transmitting, to the first user device, configuration information corresponding to each antenna panel of the plurality; selecting first configuration information corresponding to the antenna panel with the initial antenna panel index; and receiving a first uplink transmission from the first user device, wherein the first user device uses a selected first antenna panel corresponding to the initial antenna panel index and the first configuration information corresponding to the selected first antenna panel. In other aspects, rather than initially transmitting configuration information corresponding to each antenna panel, the base station may transmit the configuration information for each panel as it is selected by the first user device for an uplink transmission.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n-k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Abstract: Systems and methods for using hybrid automatic repeat request acknowledgement (HARQ-ACK) codebooks to as part of acknowledgement/negative acknowledgement (ACK/NACK) signaling regarding multiple physical downlink shared channel (PDSCH) transmissions (also termed “multi-PDSCH”) scheduled by a single downlink control information (DCI) corresponding to multiple candidate PDSCH monitoring occasions are discussed herein. Rate matching indicators for one, multiple, or all of the PDSCHs of a scheduled multi-PDSCH are discussed. Effects of invalid symbol signaling, where one or more resources corresponding to a candidate PDSCH monitoring occasion corresponding to the DCI has been indicated for uplink (UL) use or not for DL use by a base station, are discussed.

The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells.

Abstract: Improved configured grants (CGs) may include the designation of a footprint corresponding to uplink transmission of a UE, with the footprint at least partially defined by the occupied transmission time, occupied transmission frequency, and transmission power. The footprint may be adjustable and/or selectable by the UE according to the current traffic needs of the UE and within limits set for the footprint via prior signaling from the base station to the UE. The UE may indicate the actual footprint parameters/values for the UE's uplink data transmissions by transmitting CG uplink control information (CG-UCI) inclusive of the actual footprint values to the base station. The UE may transmit the CG-UCI over resources configured according to additional parameter values received via the prior signaling from the base station. The UE may further transmit uplink data on resources configured according to the actual footprint values.

Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Approaches are described that enhance the reliability of physical downlink control channel (PDCCH) detection where the PDCCH can be transmitted repeatedly with different beams. The approaches use soft combining where the user equipment (UE) combines the soft bits from each repetition, with the combined soft bits used to jointly decode the PDCCH repetitions. To support the soft combining, the UE needs to buffer the soft bits. Buffering approaches include determining what contributes towards the buffering, including scenarios where one of the linked search sets (SSs) is dropped, what is contributed in a linked SS set pair, how the duration of buffer counting is determined, and how the UE reports its maximum buffer size capability.

Abstract: Reporting capabilities regarding Cross Carrier Scheduling (CCS) with different Sub-Carrier Spacing (SCS) may include generating a message to send to a base station. The message may comprise an indication of a user equipment's (UE's) capability for CCS with different SCS. Based on the UE's capability for CCS with different SCS, a number of unicast downlink control information (DCI) per physical downlink control channel (PDCCH) monitoring occasion per span may be processed to determine scheduled resources for downlink (DL) and uplink (UL) signaling or channels. The DL and UL signaling or channels may be processed using the scheduled resources.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.

Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.
