Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for assisted connectivity techniques. For example, a UE may transmit, to an AN, a request to establish a RRC connection with a PN, and the AN may further transmit, to the PN, the request received from the UE to establish the RRC connection with the PN. After receiving the request, the PN may transmit, to the AN, one or more RRC connection parameters for the RRC connection with the UE, and the AN may further transmit, to the UE, the one or more connection parameters received from the PN for establishing the RRC connection with the PN. Based on the one or more parameters received from the AN, the UE may establish the RRC connection with the PN.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for radio link failure recovery and beam failure recovery on a secondary cell group (SCG) in dormancy state. In an example, a user equipment (UE) may determine the UE has entered a dormant state with respect to the SCG of a secondary node (SN) having a primary SCG cell (PSCell). The UE may monitor the PSCell to detect a beam failure or a radio link failure while the UE is in the dormant state with respect to the SCG. The UE may transmit, to the SN, a report based on the beam failure or the radio link failure on the PSCell being detected.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using sidelink resources allocated in an unlicensed spectrum. A method that may be performed by a first UE includes establishing a connection with a second UE for sidelink communication in an unlicensed spectrum and communicating with the second UE via the connection using one or more sidelink sub-channels in the unlicensed spectrum according to a mapping between sidelink sub-channels and resource block (RB) sets of the unlicensed spectrum, wherein the unlicensed spectrum comprises a plurality of RB sets and one or more guard bands disposed between RB sets in the plurality RB sets.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while transmitting data using at least one first bandwidth on at least one sidelink channel to at least one other UE, one or more failures of a listen-before-talk (LBT) procedure within an amount of time. The UE may transmit, to at least one of a base station or the at least one other UE, a report indicating the one or more failures. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to piggybacking opportunities for communicating downlink control information (DCI) in a semi-persistent scheduling (SPS) configuration are provided. A first wireless communication device determines a piggybacking opportunity for communicating downlink control information (DCI) in a semi-persistent scheduling (SPS) configuration. The first wireless communication device communicates, with a second wireless communication device, a first communication based on the determined piggybacking opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in an inactive state, that uplink data is to be transmitted. The UE may determine whether a timing advance of the UE is valid. The UE may, if the timing advance is not valid, determine whether the uplink data satisfies a transport block size (TB S) threshold. The UE may, based at least in part on whether the uplink data satisfies the TB S threshold, selectively transmit the uplink data via an uplink random access channel (RACH) message or a configured uplink resource, or establish a radio resource control (RRC) connection for the uplink data. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), an indicator indicating a set of start times associated with a transmission opportunity, performing a listen-before-talk (LBT) procedure for the transmission opportunity, and transmitting, to a second UE, a communication starting at a selected start time of the set of start times based on the LBT procedure being successful.
