A partial sounding method for sounding-reference-signal (SRS) is proposed. The network node may transmit the report configuration to the user equipment (UE).

The report may comprise an indicator to indicate that a first resource index in the report is associated with the first resource set or the second resource set. The network node may know that the first resource index of the report is associated with which resource set based on the indicator in the report.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

A beam measurement method is provided. A terminal obtains beam measurement result reporting configuration of a neighbor cell, and determines a reference signal configuration of beam measurement of the neighbor cell. The terminal performs the beam measurement on the reference signal of the neighbor cell based on the reference signal configuration of the beam measurement. The terminal reports a beam measurement result of the neighbor cell.

The present application relates to communication technology. Disclosed are a channel reciprocity-based precoding matrix configuration method and apparatus. The method comprises: in downlink transmission, a network side separately sends, on each antenna port associated with each transmission layer, a CSI-RS subjected to beamforming to a terminal by using beams calculated according to angle information and delay information determined on the basis of uplink channel state information, and determines a precoding matrix for downlink transmission of the terminal according to beams sent on K0 antenna ports selected by the terminal on the basis of the CSI-RS, and a beam combination coefficient set. In this way, both angle information reciprocity and delay information reciprocity between uplink and downlink channels can be used to directly calculate formed beams for transmitting the CSI-RS, without performing SVD calculation for effective channel information of each PMI subband, thereby reducing the calculation complexity of the terminal, reducing the feedback overhead of the terminal, and also improving system performance.

The method includes a terminal that receives first configuration information and second configuration information from a first network device. The first configuration information is used to indicate a first reference signal resource of a first antenna port, and the second configuration information is used to indicate a second reference signal resource of a second antenna port; or the first configuration information is used to indicate a third reference signal resource of a first quantity of antenna ports, and the second configuration information is used to indicate a fourth reference signal resource of a second quantity of antenna ports. The terminal sends a first reference signal based on the first configuration information and sends a second reference signal based on the second configuration information.

Methods and systems are provided for dynamically detecting and correcting the deactivation of beamforming from an antenna. One or more users are identified as present within a particular geographic area typically served by beamforming, and the average signal strength of the one or more user devices is monitored. If a threshold level of degradation of the average signal strength is detected, then a beamforming status is determined for one or more of the antennas serving the user device or devices. Based on the determination, corrective measures are taken and beamforming is reactivated.
