Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to transmit a configured grant (CG) physical uplink shared channel (PUSCH) including an uplink control information (UCI) without transmitting a physical uplink control channel (PUCCH). The UE determines, based on a configuration received from the base station, a first set of CG PUSCHs. Each CG PUSCH of the first set of CG PUSCHs overlaps with the PUCCH, and is configured to transmit data from the UE to the base station. The UE further determines a second set of CG PUSCHs by excluding a third set of CG PUSCHs from the first set of CG PUSCHs. and select a CG PUSCH from the second set of CG PUSCHs to carry the UCI contained in the PUCCH. The UE further transmits the selected CG PUSCH including the UCI without transmitting the PUCCH.

Abstract: Some embodiments include a system, method, and computer program product for managing power consumption of a user equipment (UE) supporting sidelink discontinuous reception (SL-DRX) in a 5G wireless communications system. A UE determines a candidate slot for sending a signal based on data sensed in various periods over a history window. Some embodiments include a processor that can determine set of candidate slots that are sufficiently sensed based on sensed periods over a history window, and determine a subset of candidate slots of the set of candidate slots based at least on an occupancy threshold over the history window. The processor can select a candidate slot from the subset of candidate slots, and transmit via the transceiver, a first signal via the selected candidate slot.

Abstract: A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.

Abstract: Methods and apparatuses are disclosed for performing fast beam tracking in a wireless communication environment. A UE signals to a gNB its capabilities for intra-symbol beam sweeping. Depending on configuration, the UE can either assume that the intra-symbol beam sweeping configuration will be implemented, or will await a response from the gNB before implementing intra-symbol beam sweeping. Although this is generally carried out during initial access between the UE and the gNB, the beam sweeping configuration can be dynamically updated by either the UE or the gNB during established communication. For example, the UE can signal a desired change via its MAC CE, and the gNB can signal its change to the UE via DCI.

Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.
