Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. 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 transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. Numerous other aspects are described.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability message associated with a number of downlink multiple-input and multiple-output (MIMO) layers supported at the UE. The UE may receive a configuration for a set of downlink MIMO layers including a first subset of downlink MIMO layers configured for a first cell and a second subset of downlink MIMO layers configured for a second cell. The UE may allocate a first set of resources to the first cell or the second cell, or both, based on the first and the second subset of downlink MIMO layers. The UE may determine a second set of resources are unallocated to the set of downlink MIMO layers and allocate the second set of resources to the first cell or the second cell, or both.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: Aspects presented herein enable updating the codebook configuration upon the changing of the cover or case of the UE. The apparatus applies a first codebook from a plurality of preconfigured codebooks. The apparatus detects a change of a cover state of the UE, wherein the change alters a transmission beam pattern at the UE. The apparatus applies a second codebook from the plurality of preconfigured codebooks based on the change of the cover state.

Abstract: Methods, systems, and devices for wireless communication are described in relation to a Multiple Subscriber Identify Module (MSIM) user equipment (UE). The UE associated with multiple network subscriptions may determine a first timing of a first set of paging occasions associated with a first network subscription of the multiple network subscriptions, wherein the first network subscription is associated with a first network; determine a second timing of a second set of paging occasions associated with a second network subscription of the multiple network subscriptions, wherein the second network subscription is associated with a second network; compare the first timing and the second timing; detect a paging time adjustment condition based on the comparing; and based on the detecting, transmit to the first network, the second network or both a random access signal using a random access resource configured to convey a paging time adjustment request.
