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 indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a reference time for updating one or more system information parameters associated with a non-terrestrial network (NTN) or updating a cell status associated with the NTN. The UE may determine an update timer length for updating the one or more system information parameters associated with the NTN or the cell status associated with the NTN. The UE may acquire, from a current cell or a new cell, a system information block (SIB) to refresh the one or more system information parameters after an expiration time associated with the one or more system information parameters, wherein the expiration time is based at least in part on the reference time and the update timer length. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a downlink communication is to be transmitted to the UE with a configurable gap. The UE may determine the configurable gap. The UE may receive the downlink communication based at least in part on the configurable gap. Numerous other aspects are provided.

Abstract: A method for wireless communication performed by a user equipment (UE) identifies multiple cell global identities (CGIs) broadcast by a cell. The method also determines a current tracking area identity of the UE from multiple tracking area identities of the cell based on a rule. The rule may be based on a preconfigured or predefined rule. The method selects a first CGI of the CGIs based on the determined tracking area identity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication of a set of interfered frequency resources that are subject to interference by a set of interfering frequency resources and communicate with a wireless communication device using at least one of: a bandwidth part configuration that is based at least in part on the set of interfered frequency resources, a communication procedure that is based at least in part on the set of interfered frequency resources, or a combination thereof. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) transmission in different frequency intervals. A method that may be performed by a user equipment (UE) includes receiving a first SSB from an entity in a non-terrestrial network (NTN) at a first time and frequency location. The method generally includes determining one or more time and frequency locations of one or more other SSBs from the entity in the NTN based on the first time and frequency location. The method generally includes monitoring for the one or more other SSBs at the determined one or more time and frequency locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein allocate and/or transmit a narrower bandwidth value for LTE MTC UEs, such as UEs that operate in a small bandwidth mode using LTE procedures, and allocate and/or transmit a wider bandwidth value for 5G MTC UEs, such as UEs that can perform hopping and/or be allocated resources outside of a legacy bandwidth. For example, the wider bandwidth value may be associated with a non-LTE carrier (e.g., a 5G carrier in a 5G bandwidth) with the same center frequency as an LTE carrier associated with the narrower bandwidth value. Some techniques and apparatuses described herein provide for initial access, signaling, paging, random access, unicast communications, frequency hopping, cell-specific reference signaling, narrowband alignment, and/or other coexistence considerations for LTE MTC UEs operating on an LTE carrier and 5G MTC UEs operating on a non-LTE carrier with a bandwidth that includes the LTE carrier.
