Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, during a random access procedure, a user equipment (UE) may receive a grant of resources for an uplink (UL) data transmission in a random access response (RAR) message. The UE may identify a scheduled slot for the UL data transmission based on a received slot of the RAR message and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified using the various techniques described herein.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.
