Abstract: Certain aspects of the present disclosure provide techniques for predicting an amount of uplink data to report in a buffer status report (BSR). A method that may be performed by a user equipment (UE) includes predicting a value of a parameter related to transmission of uplink data from the UE; determining an amount of uplink data to report in the BSR based on at least the predicted value of the parameter, and transmitting the BSR including an indication of the determined amount of uplink data.

Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a broadcast multicast service center (BMSC) device may receive, from a user equipment (UE) and via a first base station associated with a first radio access technology (RAT), a request for evolved multicast broadcast multimedia service (eMBMS) content. The BMSC device may transmit, to an access and mobility management function (AMF) device, a redirection request or a handover request, associated with the UE, from the first base station to a second base station associated with a second RAT. The BMSC device may transmit, to the UE and based at least in part on the UE being redirected or handed over to the second base station, the eMBMS content via the second base station. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. Further, the apparatus may be configured to determine that content is available for reception based on broadcast context information. In an aspect, the apparatus may be in an idle or inactive mode and may be associated with a first base station that is associated with a first radio access technology (RAT) that does not support broadcasting of the content. The apparatus may be further configured to receive a release message from the first base station, the release message including redirection information indicating a second base station associated with a second RAT that supports broadcasting of the content, establish a connection with the second base station based on the redirection information, and receive the content from the second base station using the second RAT.

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: Certain aspects of the present disclosure relate to methods and apparatus for avoiding conflicts between evolved Multimedia Broadcast Multicast Services (eMBMS) operations and paging and/or mobile originated (MO) operations in communication systems. A method for wireless communications by a user Equipment (UE) is provided. The method generally includes identifying at least one evolved Multimedia Broadcast Multicast Service (eMBMS) session available for receiving one or more eMBMS services from a base station. The method also includes taking one or more actions to reduce a conflict between receiving the one or more eMBMS services from the base station and receiving a paging message from the base station during the eMBMS session. Numerous other aspects are provided.
