Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may determine how densely user equipments are located in various regions surrounding the base station, and may assign more beams for transmission of an initial access signal in an area with more UEs. The apparatus may be a base station. The base station divides a region surrounding the base station into a plurality of sub-regions, where one region of the plurality of sub-regions covers a greater area than at least one other region of the plurality of sub-regions. The base station assigns each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions. The base station transmits at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.

Abstract: Logic may implement a restricted access window association scheme that uses information provided in traffic indication map (TIM) bitmap and restricted access window (RAW) parameter set (PS) to determine stations associated with RAWs. The TIM information element (IE) may comprise a bitmap indicating paged and unpaged stations. The RAW PS IE may comprise a range of station association identifiers (AIDs) and possibly other station selection data. Logic may determine a range of stations associated with a RAW based upon AIDs for the first and last stations in the range based upon a position for the station in the TIM bitmap. And the range of stations associated with a RAW may be independent of block associations of the first and last stations in the TIM bitmap.

Abstract: A wireless transmission system performs multi-station simultaneous transmission of data. The wireless transmission system includes wireless stations for transmitting and receiving data. Transmitter-side wireless stations, a multipath channel, and receiver-side wireless stations constitute a system for path diversity. At least one wireless station among the wireless stations determines, depending on a response packet with respective to a multi-station simultaneous transmission request packet transmitted by itself or other stations, delay amounts from a reference timing during multi-station simultaneous transmission in the wireless transmission system, and symbol waveforms that are a basis for a modulated waveform. A difference between each delay amount is set to be larger than or equal to a predetermined delay resolution for each symbol waveform, and a difference between maximum and minimum values of the delay amounts is set to be smaller than or equal to a predetermined maximum delay.

Abstract: Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on a predetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.

Abstract: For each of a plurality of users having multiple connection to a specific time slot a synchronization window of a predetermined temporal length having a center corresponding to a synchronization position is set to disallow a subsequent signal reception outside the widow. Furthermore timings of transmission for users are controlled to prevent synchronization windows from overlapping or being too distant from each other in the time slot. Thus, synchronization positions can be prevented from approaching each other or having an inverted time relationship therebetween. This process is provided by a DSP in software.
