摘要： A wireless communications system includes a number of clusters of repeaters wherein all repeaters within a cluster arc connected to a common hub via respective millimeter-wave radio links. Wireless signals received by the repeaters from end-user devices are transparently carried by the millimeter-wave radio links to respective hubs that act as concentrators for the repeaters. The hubs may be linked to a wireless network base station (in an outdoor setting) or alternatively to a server or a PBX (in an indoor environment) via a high-speed transmission facility, such as a fiber optic cable that is thus shared by all the repeaters.

摘要： A system and method for statistically modeling the operation of a directional terminal antenna in a wireless link. When using a directional terminal antenna, received power may be enhanced by as much as the antenna gain. In local scattering, however, the enhancement will be smaller. The system and method model this decrement, known as the gain reduction factor, &Dgr;, for fixed suburban paths, based on angle-of-arrival measurements. The system and method also provide the capability to statistically model the transmission performance of a directional terminal antenna in a wireless link while analyzing influences of antenna height, antenna beamwidth, distance and season.

摘要： In transmit pre-coding, a bandwidth and a feedback period to one or more CQI reporting units and a bandwidth and a feedback period to one or more PMI reporting units are assigned, respectively. Sub-divisions in time and/or frequency corresponding to the assigned bandwidths and the assigned feedback periods are dynamically adjusted based at least on uplink channel state information corresponding to the bandwidth and the feedback period assigned to the CQI reporting units, and the bandwidth and the feedback period assigned to the PMI reporting units. One or more feedback messages are generated based at least on the channel state information over the adjusted sub-divisions in time and/or frequency corresponding to the CQI reporting units and to the PMI reporting units, respectively. The bandwidth and/or the feedback period may be assigned based on the channel state information or as a function of a feedback rate.

摘要： Carrier sense multiple access (CSMA) for multiple user, multiple access, and/or MIMO wireless communications. In wireless communication systems that operate in supporting communications via one or more clusters, appropriate determination of when to begin making such transmissions on one or more clusters is made in accordance with intelligent carrier sense multiple access (CSMA) that may be performed in a number of different ways. In accordance with this, a cluster may be any combination composed of one or more channels among one or more bands. In supporting multi-cluster access, CSMA may be performed in selecting a primary cluster and performing backoff (e.g., countdown) thereon. After backoff is finished for the primary cluster, and the availability of one or more others clusters is checked, transmissions may be made using the available clusters. Alternatively, backoff may be made for each or multiple (a subset of) clusters or even individually for each respective cluster.

摘要： A method and system for determining synchronization status in a wide band CDMA (WCDMA) network may comprise calculating a signal to noise ratio (SNR) of a downlink dedicated physical channel (DPCH) based on a plurality of transmit power control (TPC) bits received via the downlink dedicated physical channel (DPCH), wherein the value of at least one of the plurality of TPC bits is not known when at least one of the plurality of TPC bits is received. The transmit circuitry may be controlled based on the calculated signal to noise ratio. The transmit circuitry may be disabled if the calculated SNR of the plurality of TPC bits is below a first channel threshold. The transmit circuitry may be enabled if the calculated SNR of the plurality of TPC bits is above a second channel threshold.

摘要： Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices). The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

摘要： Methods and systems for processing signals in a receiver are disclosed herein and may comprise generating at least one control signal that may be utilized to control a first received signal. A phase of the first received signals may be adjusted via the generated control signal so that the phase of the first received signal may be equivalent to a phase of a second received signal, where the phase of the first signal may be adjusted within a processing path used to process the first received signal. An amplitude of the first received signal may be adjusted via the generated control signal so that the amplitude of the first received signal may be equivalent to an amplitude of a second received signal, where the amplitude of the first signal is adjusted within the processing path used to process the first received signal.
