摘要： Systems and techniques for carrier aggregated beamforming using elevation control. A base station determines a first elevation to be used for transmission to a user device using a first carrier, for example, based on information received from the user device. A second elevation, for transmission to the user device based on the second carrier, is determined based at least in part on the elevation information determined for the first carrier. The first and second carriers may be used by the same base station or by different base stations, and using elevation information determined for the first carrier to determine elevation information for the second carrier avoids computation and signaling needed for separate determination of the elevation information for the second carrier.

摘要： Systems, methods, apparatuses, and computer program products for an interleaved multi-beam acquisition waveform providing concurrent beam selection, automatic gain control (AGC) and automatic frequency correction (AFC) are provided. The access point (AP) may send an acquisition waveform on multiple beams, then return and retransmit an AFC on the multiple beams thus interleaving beam switching with the acquisition and frequency correction waveforms. AGC correction can be deferred until the end, relying on the fact that the transmitter may be detected at close range using a one of the multi-beams that is attenuated.

摘要： An example technique may include controlling receiving a first block of time domain symbols and a second block of time domain symbols, converting the blocks of time domain symbols to the frequency domain to create a first pre-equalized block of frequency domain symbols and a second pre-equalized block of frequency domain symbols, respectively, applying, a linear phase shift to the frequency domain symbols to compensate for a conjugating and time-reversing of corresponding pre-spread domain symbols being performed at a transmitter before spreading of the pre-spread domain symbols, and creating a first equalized block of frequency domain symbols and a second equalized block of frequency domain symbols as a function of the first and second pre-equalized blocks of frequency domain symbols wherein at least one of the first and second pre-equalized blocks of frequency domain symbols has the linear phase shift applied.

摘要： A method of operating an array of antennas in a wireless communication system to provide user-specific azimuth and elevation beamforming is described. The method includes providing a product codebook structure consisting of both an azimuth and elevation portion. A receiver receives reference signals from a transmitter corresponding to both the azimuth and elevation portions of the array of antennas. The method also includes determining the index of the azimuth codebook portion of the product codebook from the azimuth portion of the received reference signals and determining the index of the elevation codebook portion of the product codebook from the elevation portion of the received reference signals.

摘要： Systems, methods, apparatuses, and computer program products for random access channel (RACH) with a grid of beams for communication systems are provided. One method includes transmitting, by a base station, a beacon signal in one time slot with multiple switched beams, wherein the beams cover an intended coverage area with a grid-of-beams in both horizontal and vertical directions. The method may also comprise switching receiving beams in the grid-of-beams at a network reserved random access channel (RACH) slot by following an identical or directly related beam switching pattern in a downlink (DL) beacon channel. Another method includes detecting, by a user equipment, a beam ID in the downlink beacon channel, selecting the RACH slot using the detected beam ID, and transmitting, by the user equipment, a random access channel (RACH) signature in one or multiple beam blocks within a random access channel (RACH) slot.

摘要： Communication systems may employ transmission of feedback information and responses thereto, on a wireless connection such as a millimeter wave connection. The feedback information itself may be used to influence the beamforming or beam direction used for the transmission of the feedback information. A method can comprise determining a feedback indicator regarding reception of a transmitted waveform. The method can also comprise tailoring, for example beamforming, a signal for transmitting the feedback indicator based on a content of the feedback indicator.
