A communication signal transmitting apparatus includes a transmitter; a processor, and non-transitory computer-readable storage medium storing a program for execution by the processor, the program including instructions to determine at least two different resource element groups to use to transmit a synchronization signal, each different resource element group of the at least two different resource element groups used to separately transmit the synchronization signal, and transmit the synchronization signal to user equipment on each of the resource element groups, where, for each resource element group, the synchronization signal transmitted on the respective resource element group carries at least one piece of same information, the same information is cell specific information, and the synchronization signals transmitted on the at least two resource element groups using different beams.

Precoding matrix computations for a large number of antenna arrays can be used to generate efficiencies within a wireless network. Utilizing network topology and context data in conjunction with known available network resources and mobile device measurements can facilitate gains in power and spectral efficiency and reduction in computation complexity posed by current procedures. To take advantage of multiple paths, the precoding matrix can be known at the radio units for each mobile device.

Methods, systems, and storage media are described for user equipment (UE) measurements for new radio (NR). Other embodiments may be described and/or claimed.

Certain aspects of the present disclosure provide techniques and apparatus for signaling precoder(s) for non-PMI based CSI feedback.

One example method includes receiving, by a terminal, indication information sent by a base station, where the indication information indicates a precoding matrix in a first precoding matrix set and a transmission rank corresponding to the precoding matrix, and the precoding matrix is used to precode transmit data streams at r transmission layers to obtain signals to be sent on N transmission ports of the terminal; and when r>1, a nonscalar part of a precoding matrix whose transmission rank is r in the first precoding matrix set is obtained by combining columns in nonscalar parts of r precoding matrices, and the r precoding matrices are precoding matrices selected from all precoding matrices whose transmission ranks are 1; and determining, by the terminal based on the indication information, the precoding matrix for precoding the transmit data streams.
