Abstract: Supporting transmission of multiple hybrid automatic repeat request acknowledgments (HARQ-ACKS) within a single slot may include encoding a first HARQ-ACK and a second HARQ-ACK within the single slot for transmission to a base station. The first HARQ-ACK may be transmitted via a first physical uplink control channel (PUCCH) and the second HARQ-ACK may be transmitted via a second PUCCH. Based on encoding the first HARQ-ACK and the second HARQ-ACK within the single slot, one or more additional uplink (UL) signals colliding with at least one of the first HARQ-ACK and the second HARQ-ACK within the single slot may be responded to based on a configuration of the UE.

Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A network-side device may provide a downlink control information transmission to a wireless device scheduling downlink transmission to the wireless device from multiple transmission reception points. The downlink transmission may relate to Hybrid automatic repeat request process and/or system information transmission. And the downlink control information may include information about scheduling of HARQ processes from different TRPs, and/or information about scheduling of SI transmission from different TRPs. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.

Abstract: The exemplary embodiments relate to determining that code block group (CBG) based transmissions are enabled, transmitting, via an unlicensed spectrum, configured grants comprising one or more CBG based transmissions and one or more transport block (TB) based transmissions and receiving a downlink feedback information (DFI) downlink control information (DCI) format, wherein the DFI DCI format comprises a hybrid automatic repeating request (HARQ) bitmap corresponding to the TB based transmissions and a HARQ bitmap corresponding to the CBG based transmissions. The exemplary embodiments may be implemented in a computer readable storage medium, a user equipment (UE) or an integrated circuit.

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.

Abstract: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.
