Abstract: To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention provides soft handoff to mobile stations (MSs) ( 120-123 ) in a dispatch call by sharing soft handoff information with all the MSs in the call at a base site ( 111 ). When a first MS (e.g., 120 ) needs to soft handoff, the identity of a soft handoff channel ( 135 ) at an adjacent base site ( 112 ) is shared with all the MSs. Thus, subsequent MSs (e.g. 122 ) that need to soft handoff to that adjacent base site may do so without requesting a soft handoff.

Abstract: A radio communication system controller embodies the present invention by providing extended use (306) of a communication resource (106) to a plurality of communication units. The inventive method includes the steps of assigning (402) a first communication resource to a first communication unit, and then temporarily configuring (406) the assigned communication resource as a reserved resource. The controller then receives (408), from a second communication unit, a request to transmit a second communication on the assigned communication resource. Lastly, the controller re-configures (412) the assigned communication resource to allow transmission of the second communication on the assigned communication resource.

Abstract: A controller (120), in response to receiving a request for a group call (201) targeting a group (101), allocates at least one power adjustment channel to the group call (202) and sends identification of the at least one power adjustment channel to at least some of the subscriber units in the group (203). Using the at least one power adjustment channel, the controller also sends unique power adjustment information to each of the at least some subscriber units (204). Unique power adjustment channel access information is also sent to the subscriber units so that each subscriber unit can receive its own unique power adjustment information (503) and adjust its inbound transmission power (504) in response. In this manner, efficient reverse power control is provided for multiple subscriber units thereby facilitating group calls in CDMA systems.

Abstract: A receiver that receives a stream of information symbols may detect the usability of the stream of information symbols received as follows. Upon receiving the stream of information symbols, the receiver separates the stream of information symbols into a desired portion and an undesired portion wherein the desired portion is the originally transmitted stream of information symbols and the undesired portion is interference and noise. From the undesired portion and the desired portion, the usability can be determined based on a ratio of the two portions.

Abstract: A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode (608) at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so (614).

Abstract: A mobile station ( 106 ) establishes a real time communication link via an access point ( 102 ) for carrying voice or other time-sensitive data. A WLAN subsystem ( 204 ) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used ( 614 ), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem ( 712 ), acquiring the WLAN channel ( 407 ), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.

Abstract: A communication method can inform a WLAN-to-WAN handoff process as a function, at least in part, of a determined likely future quality of service ( 35 ). In particular, a comparison ( 36 ) can be made as between the likely future quality of service being afforded by the WLAN and one or more threshold values that represent acceptable levels of service. In one embodiment projected likely quality of service values as correspond to different future points in time can be used to more completely inform the evaluation process.

Abstract: In a wireless communication system (100) having a plurality of communication cells (115, 117), and a plurality of mobile stations (118) operating within selected ones of the multiple communication cells (115, 117), a method and a n apparatus for selecting those communication cells (115, 117). Within each communication cell (115, 117), a base station (112) transmits a message directed to the mobile stations (118), and detects a response indicator in t he selected ones of the plurality of communication cells (115, 117). The respon se indicator may be an impulse radio-frequency energy transmission generated by the plurality of mobile stations (118) operating within the selected ones of the plurality of communication cells (115, 117). The base station (112) directs call traffic to the plurality of mobile stations (118) in the select ed ones of the plurality of communication cells (115, 117).
