Embodiments of the present disclosure provide mechanisms for the following procedures: network signaling for user equipment (UE) measurements; UE measurements; UE feedback; feedback adjustment at network nodes; scheduling; Acknowledgements/Negative Acknowledgements; and network-wide planning. Some or all of these mechanisms can be used in implementing distributed open-loop multi-user co-operative multi-point (MU-CoMP) technology as well as other non-CoMP, one-tier or centralized wireless transmission technologies. The mechanisms are in line with proposed no-cell technology for 5G communication networks.

Embodiments disclosed herein include distributed antenna systems (DASs) supporting expanded, programmable communications services distribution to remote communications service sector areas. In one embodiment, the DAS includes a first programmable switch for distributing downlink communications signals into one or more communications service sector sets. The DAS further includes a second programmable switch configured to distribute the one or more communications service sector sets to one or more remote communications service sector areas. A configurable extender module is also included to provide expanded routing of communications service sector sets in the DAS. In this manner, the DAS is programmable to allow any combination of communications service sector sets and expanded communications service sector sets from any number of different base stations to be routed to any combination of remote communications service sector areas and expanded remote communications service sector areas, based on capacity needs and capability of the DAS.

Systems and method for adaptive constellation mapping determine transmission formats for simultaneous transmission from multiple transmitter chains. The adaptive constellation mapping can select a winning combination of mappings using distance metrics. The distance metrics can be calculated from estimated received signal constellations at a multi-layer receiver. The multi-layer receiver can separate the data received from each of the transmitter chains. Additional systems and method can determine a whether to use adaptive constellation mapping or an alternate transmission format. Further systems and methods can determine a transmit arrangement that include selection of which of multiple transmitters will be a part of an adaptive constellation mapping transmission, the number of layers that will be transmitted by each transmitter, the transmitter chains that will be used, and which of multiple antennas that will be used.

A multi-mode transceiver arrangement configured to provide for transmission and reception of signalling of a plurality of wireless sensor network protocols, the transceiver comprising; a single transmission path and a plurality of parallel receive paths; said transmission path including a modulator element configured to modulate, at any one time, a signal for transmission in accordance with a particular one of the plurality of wireless standards and a frequency reference element configured to provide a reference frequency to generate signalling for the antenna at a predetermined frequency; said receive paths each configured to receive signalling over a different, predetermined frequency band and including a demodulator to provide a demodulated signal for processing by a controller configured to provide signals to the transmission path and receive signals from the demodulators for symbol recognition thereby enabling the multi-mode transceiver to communicate with a plurality of wireless sensor networks simultaneously.

An embodiment of a system includes a first number of antennas, a transmitter, and a receiver. The antennas are each spaced from another of the antennas by approximately a distance and are configured to provide, at one or more wavelengths that are greater than twice the distance, a channel capacity that exceeds a saturation channel capacity. The transmitter is configured to generate a second number of signals each having a wavelength that is greater than twice the distance, the second number related to a third number of signal pipes, and to couple each of the second number of signals to a respective one of the antennas. And the receiver is configured to receive from at least one of the antennas a fourth number of signals each having a wavelength that is greater than twice the distance, and to recover information from each of the fourth number of signals, the fourth number being related to the third number.

Logic of an access point may transmit a null data packet for beamforming training and transmit a beamforming report poll to the first station on a user list before receiving a transmission from the first station on the user list. Logic may wait for a timeout period to determine whether the first station on the user list will respond to the null data packet prior to transmitting the beamforming report poll. Logic may receive from the first station an indication that the first station is a slow beamforming report responder. Logic may reorder the user list to position a fast beamforming responder as the first station. And logic of the station may determine that the station is unable to complete and transmit the report so the logic may wait to transmit the beamforming report in response to a subsequent beamforming report poll frame.

Systems and methods for automatically configuring a distributed antenna system are provided. A configuration sub-system of the distributed antenna system can identify signal parameters for downlink signals received from one or more base stations via inputs of a unit in the distributed antenna system. The configuration sub-system can automatically determine a configuration plan for the distributed antenna system based on the automatically identified signal parameters. The configuration plan specifies how to combine subsets of the downlink signals for routing to remote antenna units of the distributed antenna system.

Embodiments of the present invention provide a data transmission method for a multi-antenna system, and a device. The method includes: performing first precoding processing on to-be-sent data in a first antenna direction of a multi-antenna system to generate first data; performing second precoding processing on the first data in a second antenna direction of the multi-antenna system to generate second data; and sending the second data to a receive node through each antenna port of the multi-antenna system; wherein: when the first precoding processing is first transmit diversity processing, the second precoding processing is second transmit diversity processing or second transmit spatial multiplexing processing; when the first precoding processing is first transmit spatial multiplexing processing, the second precoding processing is second transmit diversity processing. The method and the device are used to send data by using antennas in multiple antenna directions in the multi-antenna system.

A method, apparatus, and computer program for controlling allocation of control message fields in uplink transmission in a cellular telecommunication system are presented. Uplink control message fields are allocated to the resources of a physical uplink shared traffic channel according to an uplink transmission scheme selected for a user terminal. The control message fields are allocated so that transmission performance of the control messages is optimized for the selected uplink transmission scheme.

A method for channel-state information determination in a wireless network comprises determining an initial channel-state information for a wireless channel based on a search of a plurality of sets of precoding codebook elements stored in a multiple input multiple output user equipment (UE) and determining a subsequent channel-state information based on the initial channel-state information.
