摘要： The invention relates to a mobile station apparatus in a communication system. The communication system comprises a plurality of base stations for providing mobile communication service within a covered communication area. The mobile station apparatus comprises a memory for recording a predetermined access control class and determining which base station the mobile station apparatus is allowed to camp on for conducting mobile communication service, a battery for providing electrical power, a control program, and a power detector for detecting the current power of the battery, so that when the power detector detects that the power is lower than a predetermined low power watermark, the power detector issues a trigger signal. When the control program receives the trigger signal, the control program overwrites the predetermined access control class, so as to allow the mobile station apparatus to conduct mobile communication service through other base stations in the communication area.

摘要： Methods and systems are described for using location-based information to determine whether to perform a ranging procedure. A change in location of a device is identified. The identified change in location represents the distance the device has moved during an interval between ranging procedures. The identified change in location is analyzed to determine whether the change exceeds a threshold distance. If the change in location does not satisfy the threshold distance, a change in a signal quality metric of the device from the location associated with the previously performed ranging procedure to the current location is identified. The identified change in signal quality metric is analyzed to determine whether the change exceeds a threshold value. If the change in location of the device is less than the threshold distance and the change in the signal quality metric is less than the threshold value, the next scheduled ranging procedure is bypassed.

摘要： Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

摘要： Certain aspects of the present disclosure present methods and apparatus for resolving conflict between paging intervals of two different networks. For certain aspects, a multimode mobile station (MS) may select a network for monitoring based on a predefined criterion. For an aspect, the multimode MS may select a network whose paging interval starts earlier or a network whose paging interval finishes earlier. The multimode MS may also select a network that has a higher signal quality, or higher radio access technology (RAT)-based priority. In another aspect, if the multimode MS uses multiple input multiple output (MIMO), the multimode MS may split its available resources (e.g., receive chains) to simultaneously monitor paging signals transmitted by both networks.

摘要： Methods and apparatus for waking a mobile station (MS) from a power saving mode to receive a media access control (MAC) management message (e.g., DCD/UCD, MOB_NBR-ADV, and SII-ADV) the MS has not yet received. The MS may wake from the power saving mode after detecting a mismatch between a set of media access control (MAC) management message parameters last received by the MS and the information found in an enhanced broadcast control pointer information element (BCP-IE) transmitted in a downlink map (DL-MAP). In this manner, the MS may be prevented from waking up unnecessarily, thereby providing high power efficiency.

摘要： Methods and apparatus for indicating a base station's amount of ranging traffic to a mobile station (MS) and for selecting a base station (BS) for performing ranging based on the ranging traffic indication are provided. This notification may occur via a ranging loading parameter, such as a ranging loading factor (RLF) indicating the ratio of used ranging slots to available ranging slots, transmitted as a new TLV (Type-Length-Value) within the Uplink Channel Descriptor (UCD) of a (potential) serving BS or in the UCD of a Neighbor Advertisement (MOB_NBR-ADV) message for a neighbor BS. By selecting a BS with a certain level of unused ranging slots, the MS may exponentially decrease the ranging overhead (i.e., the average waiting time for the ranging procedures) when compared to a conventional MS that does not consider a BS's ranging overload when trying to perform ranging with the BS.
