Abstract: A system and method for generating a composite synchronization sequence in a communication system. In one embodiment, the apparatus is configured to provide a first synchronization sequence and a second synchronization sequence in a first domain, transform the first synchronization sequence and the second synchronization sequence into a second domain, and extend the first synchronization sequence and the second synchronization sequence in the second domain to a common length to produce an extended first synchronization sequence and an extended second synchronization sequence. The apparatus is also configured to transform the extended first synchronization sequence and the extended second synchronization sequence into the first domain, and multiply elementwise the extended first synchronization sequence by the extended second synchronization sequence in the first domain to obtain a composite synchronization sequence.

Abstract: A wireless communication network includes an assistant serving access node (415) and a principal serving access node (410). The principal serving access node (410) receives one or more measurement reports. The principal serving access node (410) communicates an assistance request to communicate one or more data packets. The assistant serving access node (415) buffers the one or more data packets before receiving the assistance request and communicates the one or more data packets to the user equipment (110).

Abstract: A wireless device detects a synchronization signal by obtaining (210), from a received signal, a sequence of samples, and calculating (220) a differentially decoded sequence from the obtained sequence of samples. The wireless device correlates (230) the calculated differentially decoded sequence with a first reference sequence corresponding to the synchronization signal, at each of a plurality of time offsets, and identifies which of the plurality of time offsets results in a largest correlation result. In response to determining (240) that the largest correlation result does not meet a predetermined reliability criterion, the wireless device correlates (250) the obtained sequence of samples with a second reference sequence, at each of a plurality of time and frequency offsets, and identifies which combination of time offset and frequency offset results in a largest correlation result. The first reference sequence comprises a differentially decoded version of the second reference sequence.

Abstract: Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller (210) and radio resource manager (220). A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.
