Abstract: Methods and apparatus for improving Circuit Switched (CS) Fallback performance, such as in an LTE network, are described. In one aspect, a UE may perform a RAU procedure before performing a CS call setup procedure when the UE has camped on a Non-DTM GERAN target after failing to access a redirection target. In another aspect, an MME may determine whether to perform a PS suspension based on an ISR status associated with a user terminal. In another aspect, an eNB may send information associated with a PS suspension to a user terminal.

Abstract translation: 描述了用于改善电路交换（CS）后退性能的方法和装置，例如在LTE网络中。 在一个方面，当UE在不能访问重定向目标之后，当UE驻留在非DTM GERAN目标上时，UE可以在执行CS呼叫建立过程之前执行RAU过程。 另一方面，MME可以基于与用户终端相关联的ISR状态来确定是否执行PS暂停。 在另一方面，eNB可以向用户终端发送与PS暂停相关联的信息。

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Abstract: Wireless communications systems as described herein may be configured to provide user equipment (UE) assisted information for caching data at a network node external to a core network (CN). In some cases, the UE may provide an acceleration indicator (AI) that a base station may receive and identify as caching information. The base station, upon identifying that the AI is present in an uplink packet, may transmit the packet to a gateway having a local cache. If the uplink packet does not have an AI, the base station may route the uplink packet according to an address (e.g., a uniform resource locator (URL)) contained in the packet.

Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message including a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

Abstract: Aspects of the present disclosure describe receiving paging messages in wireless communications. A user equipment (UE) can receive one or more parameters for descrambling non-cell specific paging messages. The UE can receive, from one or multiple base stations, a non-cell specific paging message. The UE can descramble the non-cell specific paging message based at least in part on the one or more parameters.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enabling access control in a connected mode, idle mode, and an inactive state. An exemplary method generally includes receiving access control information associated with one or more services used by the UE for communicating with the wireless communications network, receiving a request to transmit traffic using the one or more services, checking a type of the traffic against the access control information, and scheduling the traffic for transmission if the type of the traffic satisfies one or more criteria in the access control information based on the checking.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for caching content at a network component and providing the cached content to requesting UEs. An example method generally includes receiving a request for content from a user equipment, inspecting the request for information about the requested content, determining, based on information about the requested content obtained by inspecting the request, if the requested content is on a service list, and providing the requested content from a cache to the UE if it is determined the requested content is on the service list and cached at the base station or retrieving the requested content from a remote source, storing the requested content in the cache, and providing the requested content to the UE if it is determined the requested content is on the service list but not cached at the base station.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE that receives a multicast/broadcast data transmission via a group bearer. The UE receives a paging message including a type of the group bearer. In addition, the UE determines whether to remain in or change to an RRC idle mode or an RRC connected mode based on the type of the group bearer received in the paging message.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE that performs a PTT/PTX call setup for communication via MBMS. In a first configuration, the UE sets up a unicast bearer with an eNB, and sends group call setup signaling to the eNB while setting up the unicast bearer. In a second configuration, the UE sets up a unicast bearer with an eNB, and receives group call setup signaling from the eNB while setting up the unicast bearer. In a third configuration, the UE receives a group page while in an RRC idle state, and receives group call setup signaling based on information in the group page.
