Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE later enters RRC_IDLE mode and releases a radio bearer of the unicast EPS bearer while keep monitoring the multicast MBMS bearer for the DL multicast traffic.

Abstract: A method of power management for a mobile station in a multi-carrier wireless network is provided. A primary connection between the mobile station and a serving base station is first established by performing initial ranging over a primary radio frequency (RF) carrier. A secondary connection between the mobile station and the base station is then established by performing periodic ranging over a secondary RF carrier. To achieve efficient power management, the mobile station performs Open Loop Power Control and obtains long-term link measurement (CSI) of the primary carrier. The mobile station then adjusts carrier-specific parameters based on the primary carrier CSI. For RF carriers that convey on-going data traffic, Close Loop Power Control is updated per RF carrier. When the mobile station enters sleep mode operation, it receives traffic indication messages on the primary RF carrier and then dynamically wakes up one or more corresponding RF carriers for data reception.

Abstract: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

Abstract: A method of network-based positioning using sounding reference signal (SRS) is proposed. An eNodeB configures a number of parameters of a periodic SRS transmission for a user equipment (UE). The eNodeB then transmits SRS configuration data for SRS measurements performed by a location measurement unit (LMU). The SRS configuration data includes cell-specific SRS bandwidth configuration and UE-specific SRS bandwidth configuration. The SRS configuration data may further include a number of antenna ports for SRS transmission, SRS frequency hopping bandwidth configuration, information on whether SRS sequence-group hopping is enabled, and Δss when SRS sequence hopping is enabled. Upon receiving the SRS configuration data, the LMU is able to perform timing measurements over the received SRS signals from the UE. In one embodiment, the LMU detects SRS dropping to avoid performance degradation of the network-based positioning.

Abstract translation: 提出了一种使用探空参考信号（SRS）进行网络定位的方法。 eNodeB为用户设备（UE）配置周期性SRS传输的多个参数。 eNodeB然后发送用于由位置测量单元（LMU）执行的SRS测量的SRS配置数据。 SRS配置数据包括小区特定的SRS带宽配置和UE特定的SRS带宽配置。 SRS配置数据还可以包括用于SRS传输的多个天线端口，SRS跳频带宽配置，是否启用SRS序列组跳变的信息，以及当启用SRS序列跳频时的“Dgr”; ss。 在接收到SRS配置数据之后，LMU能够对来自UE的接收的SRS信号执行定时测量。 在一个实施例中，LMU检测到SRS丢弃，以避免基于网络的定位的性能下降。

Abstract: A method of UE RSRQ measurement precaution for interference coordination is provided. The UE receives radio signals of a neighbor cell under measurement. The neighbor cell applies a TDM silencing pattern for inter-cell interference coordination (TDM ICIC). The UE determines a measurement pattern that includes multiple subframes. The UE performs RSRQ measurements of the cell over multiple subframes and obtains multiple RSRQ measurement samples. The UE derives RSRQ measurement result by estimating the multiple RSRQ samples and applying a weighted average. RSRQ samples estimated to be more applicable are taken into account to more extent (e.g., applied with more weight), and/or RSRQ samples estimated to be less applicable are taken into account to less extent (e.g., applied with less weight, or discarded with zero weight). With UE precaution, a more predictable RSRQ measurement result is produced.

Abstract: An effective SCELL activation procedure is proposed to reduce the SCELL activation time. For carrier aggregation, a secondary cell (SCELL) needs to be configured and then activated before a UE can perform normal operation. In a first embodiment, the UE performs measurements on a list of candidate SCELLs before SCELL configuration. In a second embodiment, the UE performs measurements on a configured SCELL with high priority after the SCELL is configured. In a third embodiment, the UE performs deactivated-state SCELL measurements with adaptive SCELL measurement interval based on a configured measurement cycle and a state machine. Small SCELL activation time allows energy saving and network scheduling gain.

Abstract translation: 提出了一种有效的SCELL激活程序来减少SCELL激活时间。 对于载波聚合，需要配置二次小区（SCELL），然后在UE可以执行正常操作之前激活。 在第一实施例中，UE在SCELL配置之前对候选SCELL的列表进行测量。 在第二实施例中，在配置SCELL之后，UE在配置好的高优先级的SCELL上执行测量。 在第三实施例中，UE基于配置的测量周期和状态机，以自适应SCELL测量间隔执行去激活状态SCELL测量。 小的SCELL激活时间可以节省能源和网络调度增益。
