Abstract: Methods and systems are disclosed that may help a base station to adjust forward-link data rates in a given sector based on transmission-power variations in neighboring sectors. An exemplary method involves a base station that serves a first sector: (a) determining a respective transmission power for each of two or more channels of a second sector, (b) detecting a transmission-power difference between at least two of the channels of the second sector, and (c) in response to detecting the transmission-power difference: (i) determining a data rate control (DRC) adjustment for the first sector based at least in part on the transmission-power difference; and using the determined DRC adjustment to determine a forward-link data rate for at least one access terminal in the first sector.

Abstract: Disclosed herein is a method and corresponding system for management of neighbor scanning in a cellular wireless communication system. A radio access network (RAN) sends, and a mobile station receives, a neighbor list update message (NLUM) containing a plurality of different neighbor lists. The mobile station then selects one of the neighbor lists based on a determined first rank-ordering of its active set members. Once the mobile station selects one of the neighbor lists, the mobile station scans the neighbors listed in the selected neighbor list in accordance with the selected neighbor list. If the mobile station detects a change in rank-ordering from the determined first rank-ordering to another rank-ordering, the mobile station may select and transition to another one of the neighbor lists and may begin to scan the neighbors listed in the selected other neighbor list in accordance with the selected other neighbor list.

Abstract: While a first and second entity are engaging in a communication session on a wireless link, the first entity may be sending a series of power control commands (PCCs) directed to the second entity at a first transmission rate. Additionally, the first entity may monitor an actual and expected transmission-power adjustment of the second entity. Based on this monitored actual and expected transmission-power adjustment, the first entity may decide to alter the PCC transmission scheme for the second entity. For instance, if the monitored actual and expected transmission-power adjustment differs by a threshold extent, the power-controlling entity may decide to increase the PCC transmission rate for the power-controlled entity and/or increase the transmission-power adjustment instructed by PCCs directed to the second entity. In response, the first entity may begin sending the series of PCCs directed to the second entity according to the altered PCC transmission scheme.

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

Abstract: Exemplary methods and systems are disclosed herein that may, among other benefits, help a mobile station to conserve power by intelligently determining how often to scan for incoming pages. An exemplary method may be carried out by a mobile station that has most-recently registered with a radio access network in a zone of last registration, and involves the mobile station (a) determining a location of the mobile station in relation to the zone of last registration, (b) using the location of the mobile station in relation to the zone of last registration as a basis for determining a scan period to wait between scans of the paging channel; and (c) periodically scanning the paging channel according to the determined scan period. Furthermore, an exemplary method may be carried out in order to conserve battery power when a mobile station determines that its battery power is low.

Abstract: A method and system for vertical handoff of a mobile station from a first-protocol RAN to a second-protocol RAN. The method and system provide a make-before-break vertical handoff, by having the first-protocol RAN (i) acquire, on behalf of the mobile station, a traffic channel assignment defining one or more traffic channel parameters for air interface communication in the second-protocol RAN, and (ii) pass to the mobile station, via the first air interface protocol, the one or more traffic channel parameters so that the mobile station can then readily switch over to communication under the second-protocol RAN. Optimally, the acquisition and passing of the one or more second-protocol traffic channel parameters may occur without the mobile station having requested the handoff, without the mobile station having asked for the traffic channel assignment, and without the mobile station having yet begun communication with the second-protocol RAN.

Abstract: Disclosed herein are systems and methods for allocating fully-orthogonal and quasi-orthogonal spreading codes to access terminals in radio access networks based on a tolerance level for additional interference on a per-access-terminal basis. An embodiment takes the form of a method that includes receiving a request for allocation of a spreading code to an access terminal, and responsively comparing an additional-capacity number to an available-codes number. The additional-capacity number represents, based on an average contribution per access terminal to the current reverse noise, how many additional fully-orthogonal spreading codes could be allocated to access terminals without exceeding a maximum-allowed reverse noise. The available-codes number represents how many fully-orthogonal spreading codes are currently available for allocation. The method further involves allocating a fully-orthogonal spreading code to the access terminal when the additional-capacity number is greater than or equal to the available-codes number, and otherwise allocating a quasi-orthogonal spreading code.
