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.

Abstract: A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.
