Abstract: Methods, systems, and devices for wireless communications are described that provide for channel-bandwidth-attributed per-band user equipment capability reporting. A user equipment (UE) may determine a first and second set of physical layer capabilities associated with a first and second channel bandwidth, respectively. The UE may transmit a first and second UE capability report to the base station, where the capability reports may indicate the corresponding channel bandwidth and may include the UE physical layer capabilities. The UE may receive control information indicating a channel bandwidth from the base station and the UE may communicate with the base station according to the received control information.

Abstract: Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.

Abstract: A user equipment (UE) expedites cell reselection. In one instance, the UE starts a reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.

Abstract: Various embodiments may include methods for handling collisions between a first subscription and a second subscription of a wireless communication device. In various embodiments, a processor of the wireless communication device may determine whether there are persistent collisions between periodic paging wake-ups on the first subscription and periodic inter-RAT measurements on the second subscription. When persistent collisions are detected, the time for performing each inter-RAT measurement on the second subscription may be extended sufficient to enable completing inter-RAT measurements on the second subscription. The amount by which the time for performing inter-RAT measurements is extended may depend upon the timing and duration of the persistent collisions.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a base station (BS). The method generally includes receiving an indication of current remaining available transmit power from a user equipment (UE). The method further includes communicating information indicating a data rate parameter and a communication configuration to the UE. The data rate parameter is for use by the UE on an uplink with the BS. The communication configuration affects uplink transmission duty cycle on the uplink based on whether the current remaining available transmit power and a current channel state between the BS and the UE satisfy a condition. The method further includes receiving signals based on the data rate parameter and the communication configuration from the UE on the uplink.

Abstract: A user equipment (UE) expedites cell reselection by reselecting a neighbor cell prior to call setup. In one instance, the UE measures a signal quality of a serving cell and a signal quality of the neighbor cell. The UE starts a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell. The UE reselects the neighbor cell prior to a scheduled expiration of the reselection timer.

Abstract: Embodiments described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, using a reduced re-order release timer having a reduced length in response to determining that a length of a tune-away interval exceeds a threshold. In some embodiments, a reduced status prohibit timer is initiated in response to determining that the length of the tune-away interval exceeds a threshold. In some embodiments, two or more status reports are transmitted during a same status prohibit timer in response to determining that transmission window occupancy exceeds a threshold.

Abstract: Systems and methodologies are described that facilitate random access procedures using one or more fallback access schemes after initial access attempts have failed. UE equipped to determine failure of a first access request to a first base station due to interference from a second base station. Further, a UE equipped to determine the failure can do so and implement one or more fallback access schemes in response to the determination. In one example, a fallback access scheme allows the UE to select a secondary carrier frequency for communications with the first base station. In another example, a fallback access scheme allows the UE to designate the first base station as inaccessible and communicate with other base stations.

Abstract: A user equipment (UE) may expand a neighbor list available to the UE to avoid neighbor information error caused by an unexpected leakage of distant time division synchronous code division multiple access (TD-SCDMA) cells. The neighbor list, may be expanded by combining previously received neighbor information with currently received neighbor information. In some instances, a new serving cell may be selected from the previously received neighbor list instead of the currently received neighbor list.
Abstract translation: 用户设备（UE）可以扩展可用于UE的邻居列表，以避免由远距离时分同步码分多址（TD-SCDMA）小区的意外泄漏引起的邻居信息错误。 可以通过将先前接收到的邻居信息与当前接收到的邻居信息组合来扩展邻居列表。 在一些情况下，可以从先前接收的邻居列表中选择新的服务小区，而不是当前接收的邻居列表。
