Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, based at least in part on a configuration of a first random access channel associated with a macro cell, one or more parameters of a configuration of a second random access channel associated with a small cell provided by the base station. The base station may transmit an indication of the one or more parameters of the configuration of the second random access channel. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for dynamic configuration of demodulation reference signals (DMRSs). A method that may be performed by a base station (BS) includes receiving one or more uplink signals from at least one user equipment (UE); estimating a Doppler shift associated with the one or more uplink signals; determining a density of reference signals (RSs) within a slot for the at least one UE based, at least in part, on the estimated Doppler shift associated with the one or more uplink signals; and transmitting information to the at least one UE indicating an allocation of RS resources for the UE, wherein the allocation of the RS resources is based on the density of the RSs for the at least one UE.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure relate to an in-coverage user equipment (UE) relaying broadcast messages to out-of-coverage UEs using one or more messaging techniques over a sidelink channel. The in-coverage UE may monitor for broadcast messages to relay the broadcast messages to out-of-coverage UEs. In some cases, the in-coverage UE may determine to relay broadcast messages to the out-of-coverage UEs based on one or more metrics. Additionally, the in-coverage UE may determine whether the broadcast message is to be included in a groupcast, broadcast, or unicast signaling. Based on the determination to relay broadcast messages, as well as whether the alert message is to be included in a groupcast, broadcast, or unicast signaling, the in-coverage UE may leverage sidelink communications to relay broadcast messages to the out-of-coverage UEs.

Abstract: A method of wireless communication includes, in response to a trigger event detected at a first base station, performing, by the first base station, a scan of a plurality of frequencies for a synchronization signal block (SSB) transmission from a second base station. The plurality of frequencies correspond to a plurality of global synchronization channel numbers (GSCNs) associated with the first base station and the second base station. The first base station is associated with a first coverage area that is at least partially within a second coverage area associated with the second base station. The method further includes transmitting, by the first base station, one or more SSBs having an SSB configuration that is based on a result of the scan.
