Abstract: A group of nodes used for sensing in a cooperative sensing communication system (100) are selected from nodes (104-112) associated with a base station (102) operating in secondary communication mode. The group has a spatial diversity gain, as determined by a cooperative sensing index (306) that initially meets a minimum threshold. To optimize the spatial diversity gain, nodes not in the initial set are individually added to the set (408), and the index is recomputed (608). The additional node having the highest effect on spatial diversity is added to the group (614). To maintain group size, each of the original nodes is individually removed from the group (706) and the index is recomputed (708) with each initial node removed to determine which of the initial nodes provided the smallest spatial gain contribution, and is removed from the group (714).

Abstract: A method of determining operating parameters for a secondary system transmitter is described. The transmitter characteristics, including location and operating frequency band, are provided to a geo-location database. The database determines the maximum allowable transmission power that meets various specifications for different channels and conveys the power and channel(s) to the transmitter. The database estimates channel incumbent signal strengths based on the transmitter location and primary and higher-priority secondary incumbent systems, estimates the splatter levels, determines whether adjacent and co-channel interference protection ratios are met, and adjusts the allowable power level accordingly. The database also estimates aggregate co- and adjacent channel primary and secondary incumbent system interference levels at the transmitter location and predicts channel quality for each allowable channel. The estimated levels are updated using measurements of actual levels at the transmitter location.

Abstract: In a communication system (10) having a pool of communication resources (11), such resources are preferentially allocated amongst a plurality of communication services (such as, for example, voice services, single-slot packet data services, and multi-slot packet data services) in a manner that tends to facilitate subsequent expansion of selected services (such as multi-slot packet data services). In a preferred embodiment, the allocation process also tends to favor balanced as versus unbalanced expansion of certain services when comparing one physical carrier that supports the service against another physical carrier that also supports that service.

Abstract: A method and circuit are described for estimating I and Q amplitude imbalance occurring in a signal received by a direct conversion receiver (DCR). The DCR generates a mixing signal having a frequency substantially the same as the carrier signal of the signal received by an antenna. A mixing module mixes the mixing signal at different phases with the received signal to generate I and Q baseband signals. A frequency offset circuit generates an offset signal having a frequency offset from the carrier signal frequency. A coupling circuit selectively decouples the antenna from the DCR and couples the offset signal to the mixing module to generate a baseband test signal in the I and Q signal paths for determining an imbalance in the amplitudes of the baseband test signals between the I and Q signal paths.

Abstract: During a communication session (101) for a multi-network user platform (which communication session is presently occurring in a first network and is terminable by a Session Initiation Protocol server as comprises a part of that first network), one establishes (102) in the first network a Session Initiation Protocol instance as corresponds to the communication session. Thereafter, and particularly following a handoff of the communication session from the first network to a second network, one uses (104) the Session Initiation Protocol instance to maintain communications with the Session Initiation Protocol server such that the Session Initiation Protocol server does not terminate the communication session.

Abstract: During operation of a secondary communication system, nodes having different channel monitoring capabilities or requirements will cooperatively monitor possible frequencies for transmissions, each node using only a subset of all possible modulation sensing schemes. All nodes will share channel occupancy information to other nodes within the communication system. For example, a first group of nodes may monitor possible frequencies for television transmissions, while a second group of nodes may monitor the possible frequencies for APCO 25 transmissions. A group of nodes may also cooperatively monitor possible frequencies for more than one type of modulation transmission. Channel information will be shared among the nodes.

Abstract: A system and method for minimizing inter-communications system mobile-to-mobile station interference includes a plurality of base stations (BS A and BS B) and a plurality of mobile stations (MS A and MS B) each communicating with a base station using a first mode of communication. A first mobile station (MS A) sends a message using a second mode of communication upon detecting interference with another mobile station (MS B) to determine the source of the interference. Once determined, the first mobile station (MS A) communicates with its base station (BS A) which, in turn, communicates with the second mobile station's base station (BS B) using a back haul network. The second mobile station's base station (BS B) may then instruct the second mobile station (MS B) to alter its transmission characteristics based upon instructions from the second base station (BS B) in order to reduce interference and improve overall communications quality.

Abstract: A pressure activated remote microphone is provided within a communication system (100). A face mask (102) incorporates a remote microphone (118) and one or more pressure sensor(s) (122). When a user puts on the mask (102), the remote microphone (118) is enabled in response to the pressure sensed by the pressure sensors (122). When the mask (102) is removed, the remote microphone (118) is disabled in response to the change in pressure sensed by the pressure sensor(s) (122).

Abstract: A method in a mobile station including receiving an order from a serving cell for system information acquisition of a neighbor cell, wherein the order includes at least a physical cell identifier and a time limit for acquisition of the system information of the neighbor cell, acquiring the system information of the neighbor cell within the time limit for the acquisition of the system information, and reporting at least a part of the acquired system information to the serving cell.

Abstract: A method in a mobile station for receiving system information of a neighbor cell, and a corresponding method in a base station transmits an assignment of a gap sequence and an assignment of an acknowledgement resource allocation sequence from a serving cell. The mobile station uses the gap sequence to attempt to receive a system information message (e.g., MIB) of a neighbor cell. If the system information message is successfully decoded, the mobile station transmits an acknowledgement to the serving cell and both the mobile station and the serving cell discontinue the gap sequence and the acknowledgement resource allocation sequence. The gap sequence (and discontinuing the gap sequence) allows fewer subframes to be used by the mobile station to search for system information messages.
