Abstract: A user equipment (UE) can include processing circuitry configured to decode physical uplink control channel (PUCCH) configuration information received from a Next Generation Node-B (gNB). The configuration information includes a cell-specific base sequence hopping pattern. A PUCCH base sequence is selected from a plurality of available PUCCH base sequences based on the cell-specific base sequence hopping pattern and UCI information. A cyclic shift is applied to the PUCCH base sequence to generate a cyclically shifted PUCCH sequence. The cyclically shifted PUCCH sequence is encoded for transmission to the gNB using a PUCCH physical resource. The cyclically shifted PUCCH sequence carries the UCI and is code division multiplexed (CDM) with at least another cyclically shifted PUCCH sequence within the PUCCH physical resource.

Abstract: Systems, devices, and techniques for random access in a wireless communication network are described. A described technique performed by a user equipment (UE) includes transmitting a first message of a two-step random access procedure to a node of a wireless communication network; receiving, in response to the first message, a downlink control information (DCI) message via a physical downlink control channel (PDCCH) and a second message of the two-step random access procedure via a physical downlink shared channel (PDSCH) in accordance with the DCI message; determining, by the UE, a physical uplink control channel (PUCCH) resource based on the second message; and transmitting, by the UE, hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for the second message on the determined PUCCH resource.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing beam selection. An embodiment operates by receiving, from a base station, a request for a report for at least one uplink beam. In response, the embodiment generates the report for the at least one uplink beam. The report for the at least one uplink beam can include an indication that a resource corresponding to the at least one uplink beam is available for uplink beam indication. The resource can be a Synchronization Signal Block (SSB) resource or a Channel State Information Reference Signal (CSI-RS) resource. The embodiment transmits the report for the at least one uplink beam to the base station. The embodiment then receives, from the base station, an indication that the at least one uplink beam is selectable for uplink transmission based on the report for the uplink beam.
