摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may receive, from a base station, an indication of a configuration for a multi-panel transmission power control (TPC) command to be transmitted by the base station. The UE may also receive, according to the indicated configuration, a downlink control information (DCI) message including a set of TPC commands. The UE may determine, based on the set of TPC commands, a first transmit power for a first antenna panel of the UE and a second transmit power for a second antenna panel of the UE. The UE may transmit an uplink signal using the first antenna panel at the first transmit power and the second antenna panel at the second transmit power.

摘要： Embodiments are provided to enable distributed open-loop multi-user co-operative multi-point (MU-CoMP) scheduling and transmission. In an embodiment, network nodes schedule data transmissions for UEs among multiple transmission tiers that include a first transmission tier having predetermined modulation and coding and a second transmission tier having adaptive modulation and coding. The first transmission tier and the second transmission tier are in respective time-frequency resources that at least partially overlap. The network nodes transmit the scheduled data transmissions in the transmission tiers according to the scheduling for the UEs. A UE receives CoMP transmissions once it is scheduled for transmission by multiple network nodes.

摘要： A system and method of adjusting an equivalent channel for a downlink in a multiple-antenna communication system is disclosed herein. The system includes at least one user device and a base station having a plurality of analog RF chains, each analog RF chain having a plurality of antennas. The method comprises the base station obtaining equivalent channel information and adjusting the phases of the antennas in order to modify equivalent channel gains from the analog RF chains to the at least one user device, based on the equivalent channel information.

摘要： Methods and apparatus as described herein for determining whether to transmit a signal to at least one receiver of a plurality of receivers with an orthogonal multiplexing technique while signals to a remainder of the plurality of receivers are simultaneously transmitted with a non-orthogonal multiplexing technique If it is determined that the signal should be transmitted to the at least one receiver with the orthogonal multiplexing technique, simultaneously transmitting the signal to the at least one receiver with the orthogonal multiplexing technique and the signals to the remainder of the plurality of receivers with the non-orthogonal multiplexing technique. Methods and apparatus are also described for decoding the signals on the receiving end.
