摘要： In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

摘要： Techniques for limiting cell reselection in response to a variable channel are disclosed. In one aspect, a measurement of received pilot power from a base station is used as an indication of channel quality. In another aspect, hysteresis is applied to limit cell reselection, wherein the hysteresis is greater in relatively higher quality channel environments and lower in relatively lower channel quality environments. Various other aspects are also presented. These aspects have the benefit of reducing cell reselection, thus increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.
摘要翻译：公开了用于限制响应于可变通道的小区重选的技术。在一个方面，使用来自基站的接收导频功率的测量作为信道质量的指示。另一方面，应用滞后来限制小区重选，其中在相对较高质量的信道环境中的迟滞较大，并且在相对较低的信道质量环境中较低。还提出了各种其他方面。这些方面具有减少小区重选的优点，从而增加了在低功率模式下花费的时间，从而降低功耗并增加了待机时间。

摘要： Techniques for searching neighbor cells within a fixed time duration are disclosed. In one embodiment, cells in a monitored list are ranked. A first subset of the ranked cells are searched during each cycle in a series of cycles, and a subset of the remainder of ranked cells is searched in each cycle, the subset varying from cycle to cycle. In another embodiment, the ranking and searching of a subset of the ranked list of cells is performed when the number of monitored cells is greater than a pre-determined search number. In yet another embodiment, the complete list of monitored cells is searched when the number of monitored cells is less than or equal to a pre-determined search number. In various embodiments, the searching comprises one or more of intra-frequency, inter-frequency, or inter-RAT searching. Various other embodiments are also presented. Benefits include allowing prescribed levels of intra-frequency, inter-frequency and/or inter-RAT search to be performed allowing for improved base station selection and therefore improved performance and system capacity.

摘要： Techniques for cell reacquisition and reselection that increases time spent in low-power mode while effectively monitoring neighbor cells are disclosed. In one aspect, one or more windows around the expected location of the serving cell are searched in the period of time prior to the page indicator. In another aspect, intra-frequency neighbor cells are searched first to determine reselection candidates. Various other aspects are also presented. These aspects have the benefit of increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.
