摘要： An enhanced Node B (eNB) for precoding is generally described. In some embodiments, a first precoding-matrix indicator (PMI) and a second PMI is received on an uplink channel from user equipment (UE). Symbols for multiple-input multiple output (MIMO) beamforming may be precoded by the eNB using a precoder matrix recommended by the first and second PMIs, for a MIMO downlink orthogonal frequency division multiple access (OFDMA) transmission. The first PMI and the second PMI are calculated by selecting a representative codeword that is indexed by i1 and i2 for a plurality of 2TX constituent beams, the 2TX constituent beam that provides the best system evaluation metric. The i1 index for wideband and the i2 index for each subband are identified from the defined 2TX constituent beam.

摘要： Technology for a user equipment (UE) operable to decode measurement gap patterns received from a Next Generation NodeB (gNB) is disclosed. The UE can decode a per-frequency range (per-FR) measurement gap pattern received from the gNB in a New Radio (NR) system. The per-FR measurement gap pattern can indicate a measurement gap partem for monitoring selected frequency layers within a frequency range at the UE. The UE can process one or more measurements for the selected frequency layers within the frequency range. The one or more measurements for the selected frequency layers can be measured in accordance with the per-FR measurement gap pattern. The UE can encode the one or more measurements for the selected frequency layers for reporting to the gNB.

摘要： Systems and methods for prioritizing inter-frequency measurement are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may determine a priority for performing each of a plurality of inter-frequency measurement. The eNB may indicate the priority of each measurement to the UE. The eNB may transmit lists of higher priority and lower priority measurement objects. The lists may be separate and/or concatenated. Alternatively, or in addition, each measurement object may include a priority indicator, or the priority may be determined from the type of measurement object. In some embodiments, the eNB may provide indications of normal priority and low priority measurement objects and/or indications of normal priority and high priority measurement objects. The UE may perform measurements according to the indicated priorities.

摘要： A method for wireless network communication is provided. The method comprises determining, by a transmitter including a quantity of antennas, a quantity of transmitted layers; mapping a quantity of data symbols to the antennas using a quantity of precoders; generating a quantity of demodulation reference signal (DMRS) antenna ports based on the quantities of the antennas, the transmitted layers, and the precoders; and determining whether to precode at least one of the DMRS antenna ports with the precoders. The method further maps the precoded data symbols and the DMRS antenna ports to a quantity of resource elements. The method then modulates a signal comprising the resource elements and transmits the modulated signal to a receiver. Subsequently, the method estimates a channel received by the receiver over the DMRS antenna ports.
