Abstract: A method and apparatus for reducing overhead for signaling where the method includes sending a user bit map field (802) for initiating assignment of users to resources corresponding to bit positions in a resource bit map field (804), and sending the resource bit map field wherein the resource bit map field is a message indicating which resources are assigned to mobile stations. The method and apparatus include sending an indicator bit (808) wherein the indicator bit indicates one of a portion of the user bit map field is being used for purposes other than initiating assignment of users to resources corresponding to bit positions in a resource bit map field and a portion of the resource bit map field is being used purposes other than indicating which resources are assigned to mobile stations (101).

Abstract: Various embodiments are described for potentially improving coverage and/or the cell-edge outage rate and thereby the system capacity. Logic flow diagrams 10 and 20, in FIGS. 1 and 2, depict functionality performed by communication devices in the system. A first communication device, attempting to successfully receive (12) signaling from a source communication device, transmits (14) signaling indicating that it is requesting an interfering communication device to reduce transmissions that may be interfering with signaling from the source communication device. In response to this signaling from the first communication device (22), the interfering communication device reduces (24) transmissions based at least in part on what was indicated by the signaling from the first communication device. Thus, cooperative interference reduction may be achieved dynamically by receiving devices signaling other devices in the system to request interference relief when needed.

Abstract: During the course of a push-to-talk talkgroup wireless communication, decisions (21) are made regarding possible subsequent push-to-talk communication needs for the group. Based at least in part upon such decisions, a network location is identified (22) to provide talker arbitration support for this talkgroup. In one embodiment the identified network location can comprise a mobile station, such as a mobile station that comprises a member of the talkgroup. In a preferred embodiment, the talker arbitration capability is then assigned (24) to the identified network location.

Abstract: The present invention is directed to an communication unit an antenna and at least two modem cards. The first modem card is coupled to the antenna so that the first modem card transmits a first transmit signal at a first frequency during a first period and receives a first received signal at a second frequency during a second time period. The second modem card couple to the antenna so that the second modem card transmits a second transmit signal at the first frequency during the second time period and receives a second receive signal at the second frequency during the first time period. The communication unit can also include a synchronizer that is coupled to the first and second modem cards to generate a signal to synchronize the transmit and receive signals transmitted and received by the antenna.

Abstract: A method, base station, and wireless communications system for interlacing Access and Backhaul frames in a Time Division Duplex wireless communication system. The method includes monitoring Access traffic and Backhaul traffic (604). Access traffic characteristics, Backhaul traffic characteristics, and corresponding frame control overhead information are determined in response to the monitoring (606). The method also includes determining an amount of time required to deliver a substantially equal amount of bearer Access traffic and Backhaul traffic (608). A frame interlacing ration is determined (608) in response to determining the amount of time required to deliver a substantially equal amount of bearer Access traffic and Backhaul traffic. A set of Access frames (302) and a set of Backhaul frames (304) are interlaced on a frequency band using the determined frame interlacing ratio.

Abstract: A communication system network (500) having a plurality of servers (502-1 through N), each having a load level based on serving a number of clients (501-1 through M), a method includes grouping plurality of servers (502-1 through N) into a plurality of server groups G0 through Gk (503-0 through k) respectively having load levels progressively from a least amount of load level to a most amount of load level, calculating a plurality of time periods T1 through Tk corresponding to the server groups G1 through Gk, assigning load to a server selected from the servers in the server group G0 from an initial time until expiration of the time period T1, after expiration of each of the time periods T1 through Tk measured from the initial time, load assignment takes place by assigning load to a server selected from the servers in the server groups from G0 and and at least one other server group, in server groups G1 through Gk, corresponding to an expiring time period.

Abstract: To address the need for reducing audio overhang in wireless communication systems (e.g., 100), the present invention provides for the deletion of silent frames before they are converted to audio by the listening devices. The present invention only provides for the deletion of a portion of the silent frames that make up a period of silence or low voice activity in the speaker's audio. Voice frames that make up periods of silence less than a given length of time are not deleted.

Abstract: A communication system sorts packets or messages at a base station such that differential delays and absolute delays are reduced, further resulting in less needed memory at the packet selector and reduced jitter. The sorting is based on a packet identifier that is associated with each packet or message, which packet identifier includes data specific to the packet.

Abstract: When the user is actively transmitting/receiving or has recently transmitted/received on the RF channel, the user is referred to as being in an “active” state. Typically, if the user is in the active state, and neither sends nor receives data for a timer period greater than a threshold, then the user is transitioned off of the RF channel (e.g. transitioned from active to dormant). Once a transition to the dormant state has occurred, the continued transmission or re-transmission of data over an RF channel can result in a delay in re-accessing the RF channel. In order to address this problem, the idle-timer threshold is dynamically adjusted based on a communication system statistic to increase system performance.

Abstract: The method of selecting one of the resources for servicing a call includes determining a load level and a relative load capacity for each of candidate resources. The relative load capacity is based on a ratio of each candidate resource load capacity and total load capacity of all candidate resources. The candidate resource is selected by a relative ranking based on multiplication of each resource with each respective load level and each relative load capacity determination.

Abstract: A controllable playback device is placed in a mobile station (125) which is capable of playing a recorded announcement to the user of the mobile station (125) when activated by the infrastructure equipment of the cellular communication system. The cellular communication system determines if a voice channel is available (506), and if unavailable, an estimate of a retry time period is performed (512). After the estimate of the retry time period, the system forms and sends a message to the mobile station (125) including the retry estimate (515). The mobile station (125) receives the message, and activates the controllable playback device to announce to the user of the mobile station (125) that the system is fully loaded and that an access attempt at a time related to the retry estimate would likely be successful.

Abstract: To mitigate the adverse affects of the load imbalance phenomenon prevalent in spread spectrum, multi-carrier wireless communication systems, the system beneficially employs the use of handoff as a means for balancing the call traffic (commonly referred to as "load") among a plurality of carriers within the communication system. The multi-carrier wireless communication system monitors a plurality of metrics corresponding to the loading of each of the plurality of carriers in the communication system and, based upon the metrics, will handoff call traffic to and between the plurality of carriers, thereby mitigating the adverse effects associated with the load imbalance, in accordance with the invention.
