Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may transmit a random access message including a preamble and a payload. A base station may detect the preamble of the random access message. The base station, and may fail or succeed to decode the payload of the random access message. The base station may transmit, based at least in part on detecting the preamble and the different decoding outcome for the payload, a random access response. The random access response may include an uplink group grant and an indication for a type of the uplink group grant for a plurality of UEs whose preamble transmission share the same time and frequency occasion.

Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability receives information for initial access using a first initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE transmits a random access message in an initial uplink BWP that is dedicated for the UEs having the first capability.

Abstract: Wireless devices can use various super-slot formats to facilitate wireless communication using half duplex (HD) frequency-division duplex (FDD) (HD-FDD). A super-slot has a duration that can span over multiple slots and/or subframes. A super-slot can include uplink symbols and downlink symbols. The super-slot can include a guard period that separates uplink symbols from downlink symbols in the same super-slot. A super-slot can support signal repetition to provide coverage enhancement. Signal repetition can be combined with frequency hopping in a super-slot to provide diversity gain.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to maintaining, defining, configuring and implementing a coverage enhancement mode defined for radio access network. A base station may maintain parameters that define multiple coverage enhancement modes in a lookup table and may select a first coverage enhancement mode from the two or more coverage enhancement modes for use with a first user equipment to accommodate use of one or more carrier frequencies, time or frequency duplexing mode, cell size, capabilities of the first user equipment or a channel measurements report of the first user equipment, and schedule a set of control and data channels to be used for communicating with the first user equipment using a first transmission scheme defined by first parameters associated with the first coverage enhancement mode. The set of control and data channels may include uplink control and data channels and downlink control and data channels.
