Abstract: Methods and corresponding systems for reducing a peak-to-average signal ratio include determining peak and null samples of a symbol. Thereafter, an error signal is calculated that is responsive to the peak and null samples. In one embodiment the error signal has values corresponding to differences between the peak samples and a high threshold and the null samples and a low threshold. In response to the error signal, the samples are filtered to produce a filtered symbol having a reduced peak-to-average signal ratio. The error signal can also be used to calculate reserved tones on reserved subcarriers, which are combined with multi-tone subcarriers in a multi-carrier transmitter.

Abstract: A wireless transmitter is configured to map N first samples of a first discrete Fourier transform (DFT) of a group of coded symbols to M sub-carriers according to a first sub-carrier mapping rule. In this case, M is greater than N. The wireless transmitter is also configure to perform a first inverse DFT (IDFT) on the M sub-carriers to provide M second samples and clip the M second samples according to a clipping rule to provide M third samples. The wireless transmitter is further configured to perform a second DFT on the M third samples, de-map the M third samples to N fourth samples, and map the N fourth samples to O subcarriers according to a predetermined second subcarrier mapping rule. In this case, O is greater than or equal to M.

Abstract: An uplink access method in a mobile subscriber station of a broadband wireless access communication system prioritizes uplink bandwidth allocation according to QoS types of requested service. A scheduling priority is assigned to each type of service flow to guarantee the highest data rate for the high QoS service flows, and then the uplink data grants are scheduled based on this assigned priority. By assigning a priority to each connection based on the service type flow, the higher data rate connections will always have the opportunity to transmit uplink data to fulfill the high data rate QoS requirement, and fragmentation will occur only on the last lowest priority Connection ID (CID) based on the size of the last remaining data grant. The uplink access method further prevents the high priority service from stealing bandwidth from data grants intended for lower priority services by identifying when the data grant is mismatched from the amount requested by the lower level services.

Abstract: Methods and corresponding systems in a mobile station for switching communication networks include scheduling an alternate network period during a first communication session between a mobile station and a first network transceiver in a first network, wherein the first network uses a first protocol. During the alternate network period the mobile station searches for a transmission from a second network transceiver in a second network, wherein the second network uses a second protocol. A second communication session is requested between the mobile station and the second network transceiver. A second communication session is initiated between the mobile station and the second network transceiver.

Abstract: An MBMS user detection system and methodology (300) is provided for advertising available MBMS services by multiplexing user feedback requests (303) using time, frequency and/or code diversity so that one or more MBMS service users can be detected in a single polling time interval. Available MBMS services are assembled into a user feedback request (302) and assigned unique multiplex signaling codes so that a code for a first MBMS service (302.1) is orthogonal to a code for a second MBMS service (302.k). In addition, a queuing model (610) is provided for analyzing and optimizing how services are advertised in the user feedback requests.
