Abstract: A receive (Rx) chain of a wireless local area network (WLAN) transceiver may be used to assist a wireless wide area network (WWAN) transceiver in a user equipment (UE). A UE may use the WLAN Rx chain to autonomously scan and measure while the UE is connected to a first or home wireless network using its WWAN transceiver. When the UE is in a connected state, the WLAN Rx chain may be used to scan and take measurements for one or more second networks operated by a second wireless operator belonging to the same mobile virtual network operator (MVNO) as the first wireless network. In another example, the WLAN Rx chain may perform a set of inter-frequency reference signal time difference (RSTD) measurements based on observed time offsets between positioning reference signals (PRSs) from neighboring cells.

Abstract: Methods, systems, and devices are described for mobility robustness optimization. A network may be organized into base station clusters, and mobility information may be exchanged within the cluster. Each base station may then receive statistics based on the collected information. In some examples the cluster mobility statistics are used to generate a handover transition matrix identifying a probability of a UE remaining with a target base station within the cluster for a threshold period following a handover from a source base station that is also within the cluster. Based on the cluster mobility statistics, the base station may determine that the probability of the UE remaining with the potential target base station for the threshold period is low. The base station may then select an alternative handover target. The base station may then adjust the mobility parameters of the UE in order to direct it to the alternative handover target.

Abstract: Methods, systems, and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi-code embodiments, offset multi-code embodiments, and multi-user multi-code embodiments. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform. Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set-point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.

Abstract: In an embodiment, a user equipment (UE) is maintained in a shared channel state (e.g., CELL_FACH, etc.) during a period of UE-traffic inactivity that exceeds a threshold inactivity period associated with transitions of the UE from the shared channel state to a dormant state (e.g., CELL_PCH or URA_PCH, etc.). While the UE is being maintained in the shared channel state, the UE receives a request to set-up a communication session. The UE transmits, in response to the received request, a message on a reverse-link shared channel to an access network to facilitate set-up of the requested communication session.

Abstract translation: 在一个实施例中，在超过与UE从共享信道状态的转换相关联的阈值不活动周期的UE流量不活动期间，用户设备（UE）被维持在共享信道状态（例如，CELL_FACH等） 到休眠状态（例如，CELL_PCH或URA_PCH等）。 当UE正在维持在共享信道状态时，UE接收建立通信会话的请求。 UE响应于接收到的请求，在反向链路共享信道上向接入网络发送消息以便于建立所请求的通信会话。
