    摘要: A communication pathway (145) can be established between physically collocated narrowband (135) and broadband (105) devices. The narrowband device (135) can identify a communication channel. A transmission frequency used by the broadband device (105) can be spectrally-proximate to a reception frequency used by the narrowband device (135) in a frequency range associated with the communication channel, resulting in interference of the narrowband device's (135) reception when the broadband device (105) is transmitting and the narrowband device (135) is receiving concurrently. The narrowband device (135) can instruct the broadband device (105) to switch to a transmission spectrum block that is spectrally separated from the reception spectrum block of the communication channel to minimize interference between the devices when the narrowband device (135) handles a call assignment.

    摘要: A method, device, and system for establishing and maintaining a multicast group call. The method includes monitoring one or more link parameters for each of a plurality of communication devices associated with the multicast group call. The method further includes selecting, for each of the plurality of communication devices, a sector from a plurality of permitted sectors, the selected sector providing an associated highest signal strength for the communication device and forming a multicast communication zone based on the selected sectors. The method further proceeds with calculating a signal to interference plus noise ratio (SINR) for each communication device based on the formed multicast communication zone, identifying a communication device with a lowest SINR, updating a spectral efficiency metric relative to the formed multicast communication zone based on the lowest SINR, and establishing the multicast group call when the updated spectral efficiency metric meets a minimum expected spectral efficiency metric.

    摘要: Methods and apparatus are provided for mitigating interference between spectrally distinct wireless communication networks employing co-located, collaborating radios. A first base station is in a first network and communicates with a first radio within a first frequency range, and a second base station is in a second network and communicates with a second radio in a second frequency range. The first and second radios are geographically co-located, for example, within a public safety vehicle. The first radio determines a maximum level of interference it will accept based on current operational parameters, and communicates a corresponding threshold value to the second radio through a data link. The second radio sends a request to its base station to employ interim scheduling constraints governing uplink transmissions from the second radio, to thereby limit out of band emissions received by the first radio to a range that is less than the threshold interference level.

    摘要: A method (200, 300) for supporting telecommunications over a wide area network. The method can include receiving a first message from a first communications site (110), the first message communicated through a logical port (174) at the communications site and maintaining the logical port open for at least a minimum period. A second message can be received from a second communications site (112), the second message requesting an identifier associated with the first communications site. Further, a third message can be communicated to the first communications site through the logical port. The third message can identify the second communications site as a candidate for establishing a peer-to-peer communications link over which telecommunications content may be communicated to a first remote unit (104).

    摘要: When a sequence of data bits is to be transmitted, the sequence is precoded into data symbols and organized as data frames. For each data frame, a number of phase reference points at predetermined intervals within the data frame are required to allow a receiving device to sufficiently estimate channel effects on the transmitted data frame. If a data frame has a field where inclusion of pilot symbols is undesirable, and if a phase reference point is required within that field, a set of pilot symbols associated with that phase reference point is generated and inserted into the data frame prior to the beginning of the field. The values for each of the pilot symbols in the set are chosen so as to force the phase reference point to a desired phase state.

    摘要: Communication units are provided access to a communication system (100) in the following manner. A base station (202) receives, from a requesting communication unit, a request, via a shared inbound communication resource (209), for an available message path (207). When a dual-mode outbound communication resource is operating in a control mode (205), the message path (207), having a first inbound communication resource (204) and the dual-mode outbound communication resource operating in a partial control mode (206), is assigned to the requesting communication unit. Thus, the shared inbound communication resource is consistently available, providing access to the communication system.
