Abstract: An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

Abstract: A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

Abstract: A method of wireless communication at a user equipment (UE) is presented. The UE may include one or more antennas which are shared between a first network connection and a second network connection in a dual connectivity mode. The method includes reporting a first sounding reference signal (SRS) antenna-switching capability to a base station. The method also includes transmitting an SRS to the base station via a second SRS antenna-switching capability when the first network connection has priority over the second network connection, where the second SRS antenna-switching capability is reduced with respect to the first SRS antenna-switching capability.

Abstract: A user equipment (UE) can connect to an evolved universal terrestrial radio access network (E-UTRAN) new radio (NR) dual-connectivity (EN-DC) network using both a Long Term Evolution (LTE) anchor link and a 5G NR non-anchor link. The UE shares RF chain components (e.g., antennas) between the LTE and NR links. The UE uses various techniques for controlling or modifying NR sounding reference signal (SRS) transmissions and/or LTE operations to avoid interruption on LTE operations due to NR SRS transmissions.

Abstract: The present disclosure relates to resolving out-of-sync uplink grants for communication in an unlicensed spectrum. For example, a user equipment (UE) may receive an uplink grant from a network entity on a downlink communication channel, wherein the uplink grant is associated with a system frame number (SFN). The UE may further determine, based on the SFN, that the uplink grant is out of order with one or more stored uplink grants within a queue. Additionally, the UE may insert the uplink grant in an ordered position within the queue relative to the one or more stored uplink grants.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for triggering the single signal during the first buffer period to concurrently adjust a first plurality of gain states of a first plurality of low-noise amplifiers associated with a first expected reception of the first symbol on the first component carrier and a second plurality of gain states of a second plurality of low-noise amplifiers associated with a second expected reception of the second symbol on the second component carrier, and receiving the first symbol via the first component carrier and the second symbol via the second component carrier after the first buffer period.
