Abstract: 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.

Abstract translation: 本公开的某些方面提出了用于解决两个不同网络的寻呼间隔之间的冲突的方法和装置。 对于某些方面，多模移动台（MS）可以基于预定准则来选择用于监视的网络。 对于一个方面，多模MS可以选择其寻呼间隔开始更早的网络或其寻呼间隔更早完成的网络。 多模MS还可以选择具有较高信号质量或更高无线电接入技术（RAT）优先级的网络。 在另一方面，如果多模式MS使用多输入多输出（MIMO），则多模式MS可以分割其可用资源（例如，接收链）以同时监视由两个网络发送的寻呼信号。

Abstract: 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.

Abstract: Methods and apparatus for reducing power consumption of a mobile station (MS) during layer 3 (L3) peer-to-peer (P2P) communications employing a request/response message pair are provided. To save power, the MS may enter a power saving mode after transmitting a request message and initiating a timeout timer for the message pair, wherein the power saving mode may have an interval available for receiving the response message and an unavailable interval. The timeout timer may be suspended during the unavailable interval and resumed during the available interval such that the timeout timer is effectively lengthened.

Abstract: Methods and systems for utilizing a multicast/broadcast connection identifier (CID) scheduling message in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame in an effort to bypass at least a portion of the Media Access Control (MAC) protocol data unit (PDU) parsing of the frame are provided. By bypassing at least a portion of the MAC PDU parsing of the OFDM/OFDMA frame (which may be in accordance with one or more standards of the IEEE 802.16 family of standards), a particular user terminal need not spend a lot of overhead in the CID filtering process, determining which MAC PDUs are intended to be processed by the MAC of that particular user terminal. Furthermore, for certain embodiments, a user terminal may power down related circuitry during the terminal's bypassing time period(s) of the OFDM/OFDMA frame in an effort to save power.

Abstract: Methods and apparatus for easily and quickly returning to a first radio access technology (RAT) network when handover to a second RAT network is cancelled are provided. The methods and apparatus may involve a mobile station (MS) entering idle mode before handover to the second RAT network is completed and requesting a serving base station (BS) to retain MS service and operational information, as well as service flow state information. In this manner, should handover to the second RAT network be cancelled before completion, a re-entry to the first RAT network may be expeditiously performed using the retained MS information.

Abstract: The present invention relates to a method for determining a nearest base station with respect to a mobile station from M base stations. First, the mobile station compares strengths of M signals received from M base stations with each other to determine a first base station, which has a strongest signal among M signals. Then, P strength differences of the strongest signal with P signals selected from the other (M-1) signals respectively are obtained. Finally, the first base station is determined as being the nearest base station when all strength differences are respectively larger than a predetermined value.
