Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive remaining minimum system information (RMSI) from a base station (BS); determine an initial active uplink bandwidth part based at least in part on the RMSI; and use the initial active uplink bandwidth part for a random access channel (RACH) procedure between the UE and the BS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.

Abstract: In aspects, a base station and a user equipment (UR) exchange synchronization signal blocks (SSBs) carrying a SFN identity, and a waveform of the SSBs has a secondary synchronization signal (SSS) symbol preceding a primary SS symbol. In aspects, a base station transmits a radio access network area code (RAN-AC) SS and RAN-AC page are quasi co-located (QCL). In aspects, a base station transmits a RAN-AC SS over a SFN while avoiding overlap of RAN-AC SS resources with channels employed for initial access of update area cells. In aspects, a base station provides a control resource set (CORESET) to a UE upon release from a connected slate, and the UR receives a RAN-AC paging PDCCH based on the CORESET. In aspects, a base station transmits a SFN wake up signal (WUS) when there is a grant for paging, and the UK monitors for the WUS.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes operating in narrowband communications, receiving a message in a physical broadcast channel via the narrowband communications, identifying a message type of the message in the received physical broadcast channel, decoding a master information block in the physical broadcast channel based on the identified message type, and identifying a search space for a physical downlink control channel for receiving a system information block based on the decoded master information block. In some cases, the method includes coexisting with an additional device operating in wideband communications and identifying an indication in the decoded master information block that indicates an additional master information block is to be transmitted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide information identifying a first time offset between a first time associated with a measurement performed by the user equipment and a second time associated with a measurement gap or a time value of a serving cell of the user equipment, receive information identifying a second time offset between the second time and a third time, wherein the second time offset is based at least in part on the first time offset, and/or transmit a random access message at the third time based at least in part on the second time offset. A scheduling entity may coordinate a random access procedure associated with the random access message based at least in part on the second time offset. Numerous other aspects are provided.
