Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which user equipment performs a circuit-switched fallback procedure to connect to a CDMA2000 network. The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability.

Abstract: Methods, systems, and devices are described for discontinuous transmission and/or discontinuous reception in time division duplex (TDD) systems that may have data transmission formats dynamically reconfigured. An initial uplink-downlink (UL-DL) configuration for TDD communication between an eNB and user equipment (UE) may be established. This initial UL-DL configuration may be reconfigured to a different UL-DL configuration for one or more UEs in communication with the eNB. When a UE switches to discontinuous reception (DRX) mode, it may monitor control information from the eNB during DRX on periods, a frequency of the DRX on periods based on a reference UL-DL configuration irrespective of any reconfiguration of UL-DL configuration for a particular UE. In some aspects, a UE that is operating in a UL-DL reconfiguration mode may, upon entering DRX mode, autonomously discontinue operating in the UL-DL re-configuration mode.

Abstract: A UE determines a need to deactivate one or more bearer contexts. The UE then selects for deactivation one or more active bearer contexts based on a context selection criteria, to avoid exceeding a maximum number of allowable active bearer contexts for the UE. The context selection criteria may relate to one or more of: current usage of active bearer contexts, information from applications associated with active bearer contexts, priority level of applications associated with active bearer contexts, order of active bearer context creation, measure of data activity through active bearer contexts, quality of service associated with active bearer contexts, type of service, e.g. voice or data, for which bearer contexts were activated, bandwidth allocations of active bearer contexts, a criteria predefined by the UE, network or user, or a random selection. Once one or more active bearer contexts have been selected, the UE deactivates the selected active bearer contexts.

Abstract translation: UE确定需要去激活一个或多个承载上下文。 然后，UE基于上下文选择标准选择去激活一个或多个活动承载上下文，以避免超过用于UE的允许的主动承载上下文的最大数目。 上下文选择标准可以涉及以下中的一个或多个：活动承载上下文的当前使用，与活动承载上下文相关联的应用的信息，与活动承载上下文相关联的应用的优先级，活动承载上下文创建的顺序，数据活动的度量 活动承载上下文，与活动承载上下文相关联的服务质量，服务类型，例如， 语音或数据，其中承载上下文被激活，活动承载上下文的带宽分配，由UE，网络或用户预定义的标准，或随机选择。 一旦选择了一个或多个活动承载上下文，则UE去激活所选择的活动承载上下文。

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may support dual connectivity. That is, the UE may establish communications with a master node and a secondary node of a wireless communications network. The master node may correspond to a master cell group (MCG) and the secondary node may correspond to a secondary cell group (SCG). In some examples, as described herein, the UE operating in dual connectivity may collect data for optimization of the wireless communications network or upon detecting a failure associated with the master cell group or the SCG and transmit the collected data to a network entity (e.g., one of the master node or the secondary node), where the collected data is based on the SCG being in a deactivated state. In some examples, upon receiving the collected data, the network entity may attempt to recover from the failure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first common frequency resource (CFR) within a bandwidth part (BWP) and a second CFR within the BWP. Accordingly, the UE may receive, using a first numerology, a non-group-common communication at least partially in the BWP. The UE may also receive, using the first numerology, a group-common communication at least partially in the first CFR, and receive, using a second numerology, a group-common communication at least partially in the second CFR. As an alternative, the UE may receive an indication of a CFR within a BWP. Accordingly, the UE may receive, using a first numerology, a non-group-common communication in the BWP and a first group-common communication in the CFR, and receive, using a second numerology, a second group-common communication in the CFR. Numerous other aspects are described.
