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 transmit, based on detecting the paging time adjustment condition, a paging frame offset adjustment request to the first network, the second network or both.

Abstract: Methods, systems, and devices for wireless communications are described to support transmission of a resource modification information request from a user equipment (UE) to a base station, where the resource modification request may request an increased density of uplink transmission occasions. For example, the resource modification request may request an increase from a first density of uplink transmission occasions configured for the UE. The resource modification request may include a request for a decreased periodicity of uplink transmission occasions, an increased number of groups of repetitions for uplink transmission occasions, an increased number of resource blocks for uplink transmission occasions, or an increased modulation coding scheme for uplink transmission occasions. The base station may receive the resource modification request and may transmit a message to the UE, which may indicate a modified or new uplink grant configuration for uplink transmission occasions having a higher density (e.g., a second density).

Abstract: This disclosure provides systems, methods, and apparatuses to enable a user equipment (UE) and a base station to improve reception of a random access response (RAR) by the UE in an unlicensed spectrum. A network may define a procedure for calculating a random access radio network temporary identifier (RA-RNTI) specific to unlicensed spectrum based on an extended RAR window. The calculation procedure may allow UEs transmitting in the window to calculate a unique RA-RNTI and identify a RAR addressed to the UE using the unique RA-RNTI. Additionally, or alternatively, a base station may transmit a RAR including timing information associated with a corresponding random access request. Accordingly, a UE may receive the RAR and compare the timing information with its own random access request in order to determine whether the RAR is addressed to the UE. Additionally, a UE may monitor a secondary cell or a sub-band for the RAR.

Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communications in a network are provided. A user equipment (UE) may generate during a first time period, an uplink (UL) communication signal based on a scheduled grant or a configured UL grant. The UE may detect a downlink (DL) communication from a base station (BS) during a second time period after the first time period. The DL communication is devoid of the scheduled grant and the configured UL grant. The UE may transmit to the BS, the UL communication signal based on the scheduled grant or the configured UL grant in response to detecting the DL communication.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a base station (BS) operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communications and more specifically for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. In some implementations, a user equipment (UE) may use a timer to maintain an ON duration in a DRX cycle based on receiving a downlink control information (DCI) message with a data-to-feedback timing indicator (for example, a K1 value) indicating a non-numeric value for a data message. For example, the UE may receive a DCI message with feedback timing for the data message based on maintaining the ON duration. In some other implementations, a UE may use a timer to maintain an ON duration following a feedback opportunity to support dynamic group-based HARQ messaging. For example, the UE may receive a DCI message requesting a retransmission of feedback information based on maintaining the ON duration.

Abstract: Generally, the described techniques provide for a core network signaling to a base station a delay budget configuration that indicates a determined latency for communications between a core network, base station, and a user equipment (UE). In some cases, the core network may determine a first variable delay budget between the core network and a base station based on capability information associated with the wireless communications system. The core network may transmit the delay budget configuration to the base station, where the delay budget configuration may include the first delay budget. The base station may be able to determine a delay between the UE and the base station based on the delay budget configuration. Using the delay budget configuration, the base station may then schedule communications with the UE.
