Communication of uplink control information
Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit directional primary synchronization signals (DPSSs). A UE or other suitable apparatus can then find an appropriate RACH symbol from its best DPSS beam index and transmit PUCCH information in those symbols.
