    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.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

    Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for establishing, by a user equipment (UE), a first time period to evaluate one or more quality parameters of one or more reference signals, wherein the first time period is based on at least one of a number of panels of the UE or a number of beams that the UE monitors simultaneously; determining, by the UE, a quality parameter of a beam or a cell based on the one or more quality parameters of the one or more reference signals; and determining, by the UE, whether the one or more quality parameters of the one or more reference signals exceeds a quality threshold.

    IPC: H04W74/08

    Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, via a control channel, an order message instructing the UE to perform a random access channel (RACH) procedure, and selecting to perform a first RACH procedure or a second RACH procedure based on a preamble preparation time gap between the order message and a first occasion for transmitting a RACH preamble, or a payload preparation time gap between the order message and an occasion for transmitting a RACH payload, or both.

    Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.
