Abstract: Method and apparatus are described for wireless communication. A user equipment (UE) located at a public land mobile network (PLMN) border area may modify cell selection parameters in order to leave a current PLMN for a more favorable visited PLMN (VPLMN). The UE may, for example, identify the border area by monitoring GPS coordinates, identifying a mobile country code (MCC) of a network, searching for a background PLMN after experiencing a number of uplink transmit failures, or by detecting a high block error rate (BLER). Additionally or alternatively, the UE may have certain physical or environmental constraints that create a mismatch between the Downlink (DL) reception range and the Uplink (UL) transmission range, and this mismatch may be a basis for, or may be accounted for, in modifying cell selection parameters.

Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.

Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Abstract: Methods, systems, and devices for IMS based WWAN-WLAN mobility are described. A user equipment (UE) may generate channel quality metrics and media performance metrics for a source radio access technology (RAT). The UE may then select a state for the source RAT metrics.

The UE may make a handover decision based on the states of the RATs and on priority levels for the RATs.

Abstract: The application relates to a wireless relay device which acts as a mobile hotspot, in particular to enable non-4G-LTE-capable IMS clients to establish IMS connections to the 4G-LTE network. Such a device is also referred to as MiFi router, SoftAP or software hotspot. In order to ensure QoS for all IMS clients on the LTE network, there may be one or more policies in place limiting the number of concurrent connections between IMS clients and the network via a particular relay device. Such policies might operate on a first-come-first- serve basis. However, in certain situation, such policies might be unsatisfactory because different connections might be associated with different priorities. Therefore the application proposes to determine the priority associated with the device seeking connection establishment (522) and handle the connection accordingly, i.e. either to terminate a connection of lower priority (523) or to reject the connection if the priority is lower than the priorities of the other connections (526).

Abstract translation: 该应用涉及用作移动热点的无线中继设备，特别是使得能够支持非4G-LTE的IMS客户端能够建立到4G-LTE网络的IMS连接。 这样的设备也被称为MiFi路由器，SoftAP或软件热点。 为了确保LTE网络上的所有IMS客户端的QoS，可能存在一个或多个策略来限制经由特定中继设备的IMS客户端和网络之间的并发连接的数量。 这些政策可以先到先得。 然而，在某些情况下，由于不同的连接可能与不同的优先级相关联，所以这些策略可能不能令人满意。 因此，应用程序提出确定与寻找连接建立（522）的设备相关联的优先级并相应地处理连接，即要么终止较低优先级的连接（523），要么拒绝该连接，如果优先级低于 其他连接（526）。

Abstract: Certain aspects of the present disclosure relate to techniques for increasing the emergency call success rate by reducing the number of retries in a same domain. According to one aspect, a multi-mode user equipment may measure a first time period upon a first attempt of establishing an emergency call in a first RAT network. The UE may use a configurable parameter to determine a number of times that the UE may retry the emergency call in the first RAT network after expiration of the first time period without establishing the emergency call or after a failed attempt of the emergency call during the first time period. The UE may switch to a second RAT network if the UE fails in establishing the emergency call in the first RAT network after retrying the determined number of times.
