Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may establish, via a sidelink signaling interface, a unicast link between the remote UE and a relay UE; establish a connection with a base station via the relay UE, wherein a message associated with establishing the connection is communicated via the unicast link; establish one or more bearers based at least in part on a radio bearer configuration received from the base station via the connection; establish, with the relay UE, one or more sidelink access stratum entities for the one or more bearers using one or more sidelink radio resource control messages based at least in part on an access stratum configuration received from the base station via the connection; and receive or transmit control-plane or user-plane traffic via the one or more bearers.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a report of a maximum transport block size supported by the UE for if hybrid automatic repeat request (HARQ) feedback is enabled and a maximum transport block size for is HARQ is disabled. The UE may receive, based at least in part on transmitting the report, one or more transport blocks that have a transport block size that does not exceed the maximum transport block sizes supported by the UE. In some aspects, the UE may receive an indication of a length of a span for receiving a set of bits from channel encoder output for a transport block or a redundancy version of a transport block. Numerous other aspects are provided.

The disclosure describes techniques for automatically pairing multiple source devices to a sink device in response to a single source device being paired to the source device. For instance, in response to a single source device being manually paired to wireless earbuds, the techniques may automatically pair other source devices that are associated with a common user account. In addition, this disclosure describes techniques for configuring a sink device to periodically broadcast advertisement messages indicating a current state of the sink device, which enables source devices that receive the advertisement message to determine whether to establish a connection with the sink device based on a current state of the sink device.

A UE may receive a BFD-RS and calculate, based on the BFD-RS, one or more of a value of an RSSI or at least one of a value of an SNR or a value of an RSRP, such that the UE may report a BFI based on the calculated values. The UE may initiate at least one of a total BFI timer or a consecutive BFI timer when a first BFI of a plurality of BFIs is stored, and increment at least one of a total BFI counter or a consecutive BFI counter when each of the plurality of BFIs is stored. A BFD procedure may be performed if at least one of the total BFI counter is greater than or equal to a maximum total count or the consecutive BFI counter is greater than or equal to a maximum consecutive count prior to an expiration of respective BFI timers.

Methods, systems, and devices for wireless communications are described in which control information is transmitted using a single carrier (SC) waveform in time domain blocks without a cyclic prefix (CP). A base station may configure a user equipment (UE) for control information transmissions using a SC waveform without CPs in time domain blocks, and may activate the SC waveform without CPs in time domain blocks based on one or more parameters. The control information may be non-uniformly segmented across two or more time domain blocks or two or more portions of a time domain block. A reference signal, such as a demodulation reference signal, may be transmitted in the time domain blocks, where the reference signals may be distributed evenly or unevenly across the time domain blocks.
