Disclosed is a wireless communication base station apparatus whereby it is possible to prevent degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. In this apparatus, a setting section (105) sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. In the case of symbols that are mapped to antennas (110-1) to (110-4), an arrangement section (106) arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, in the case of the symbols that are mapped to the antennas (110-5) to (110-8), the arrangement section (106) arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section (105), the characteristic cell reference signals that are employed solely by the LTE+ terminals.

The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Methods, systems, and devices for wireless communications are described. For instance, a UE or base station may identify a first portion of a payload associated with a first priority and a second portion of the payload associated with a second priority less than the first priority. The UE or base station may select a first matrix associated with a first domain for the first portion of the payload and a second matrix associated with a second domain for the second portion of the payload based on a first maximum index interval for the first matrix being larger than a second maximum index interval for the second matrix. The UE may transmit or the base station may receive the first portion of the payload using one or more sequences associated with the first matrix and the second portion of the payload using one or more sequences associated with the second matrix.

When signals are simultaneously received from K transmission-side apparatuses by a receiving antenna, and repetition is performed by the K transmission-side apparatuses, an information processing apparatus is configured to: in order to obtain a transmitted reference signal x(k,n) transmitted from a transmission-side apparatus k (k=1, . . . , K) by the n-th reference signal transmission in the repetition, acquire a phase rotation amount φ(g,n) given to a transmitted reference signal x(k) and assigned to a group g to which the transmission-side apparatus k belongs and transmit the phase rotation amount φ(g,n) to the transmission-side apparatus k. The phase rotation amount φ(g,n) is acquired so that received reference signals from transmission-side apparatuses not belonging to the group g are cancelled when a phase rotation amount opposite to the phase rotation amount φ(g,n) is given to a received reference signal r(n), and the first to N-th received reference signals in the repetition are added.

The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Disclosed are a data processing method and apparatus, a device, a storage medium, and a processor. The data processing method includes: acquiring a first sequence, where the first sequence includes one of: a sequence obtained by processing a first specified element of a second sequence, or a sequence acquired from a first sequence set, and the first sequence set includes one of: a sequence set obtained by processing M sequence sets, or a preset first sequence set; and processing first data by using the first sequence, where M is an integer greater than or equal to 1.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a CSI report setting that hastens CSI feedback for SVD-based precoding. More specifically, a UE may receive a configuration from a base station for a CSI report setting for providing DL interference feedback to the base station. The configuration may include information indicating a measurement resource on which an interference measurement is performed for generating the DL interference feedback. The UE may transmit a SRS and the DL interference feedback to the base station, the DL interference feedback being independent of the SRS, such that the UE may receive pre-committed CSI-RS from the base station based on the transmitted SRS and DL interference feedback.

In a communications system which complies with LTE including a base station which transmits data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and a mobile terminal, in a case in which an uplink scheduling request signal is transmitted by using an S-RACH when an Ack/Nack signal is being transmitted by using an Ack/Nack exclusive channel, the transmission of the Ack/Nack signal is stopped while the uplink scheduling request signal is transmitted.

A method for implementation by a base station controlling at least one cell of the network is provided. It may comprise allocating to an interferer terminal attached to the cell and identified by the base station as being capable of interfering with at least one communication established by this terminal or to a neighbor cell an open temporary network identifier shared by a predetermined number of interferer terminals attached to the cell and a code making it possible to identify the interferer terminal among these interferer terminals, publishing this identifier, sending to the interferer terminal, in at least one configuration message, of the open temporary network identifier and the code and inserting this code, in a field of a physical control channel allocating resources for transmitting over the cellular network to the interferer terminal, this physical channel being encoded using the open temporary network identifier and emitted on the network.

The present disclosure relates to a 5.sup.th generation (5G) or pre-5G communication system for supporting a higher data transfer rate after a 4.sup.th generation (4G) communication system such as long term evolution (LTE). A method for operating of a transmitting end in a wireless communication system includes allocating a first resource for a first service and a second resource for a second service, determining a precoder for controlling interference between the first service and the second service, precoding a first signal for the first service using the precoder, and transmitting the precoded first signal and a second signal for the second service through the first resource and the second resource. At least one part of the first resource overlaps with the second resource.
