The present invention relates to a method and device for inter-cluster cooperative communication in a mobile communication system. A central unit operating method for inter-cluster cooperative communication in a mobile communication system comprises processes comprising: a process of receiving channel data from serving sectors in a serving cluster; a process of respectively receiving the magnitude of change of a target function for scheduling depending on whether the serving sector is blank, from neighboring sectors in neighboring clusters of the serving cluster; and a process of determining the blank pattern of the serving cluster, by using the channel data received from the serving sectors, and the magnitude of change of the target function received from the neighboring sectors in neighboring clusters.

A device and method for transmission and reception of control and data channels with a group reference signal (GRS). A GRS may include a first common reference signal associated with a first group of users and a second common reference signal associated with a second group of users. Some users or channels can be grouped to use one set of common reference signals and other users or channels can be grouped to use another set of common reference signals.

A communication system including a plurality of radio base stations and a control apparatus coupled to the plurality of radio base stations, the control apparatus comprising a first memory and a first processor configured to determine at least one transmission pattern that indicates a combination of transmission states for each of the plurality of radio base stations at a specified timing, and transmit, to each of the plurality of radio base stations, control information including information that indicates an allocation of radio resources determined based on the at least one of transmission patterns, wherein each of the plurality of radio base stations are comprises a second memory and a second processor configured to execute, based on the control information, transmission control on a terminal that communicates with each of the plurality of radio base stations.

Method to perform joint scheduling in the downlink or in the uplink of a centralized OFDM radio access network for a plurality of users considering time, frequency and space domains, scheduler device thereof and computer program products.

The method to be applied in the downlink or in the uplink of a centralized radio access network based on OFDM, whereby a set of remote radio heads of a set of remote units are connected to a central unit, that performs all (or part of) the radio-related processing tasks, wherein the scheduling exploit CoMP, NOMA and RF conditions and resource blanking techniques.

A baseband receiving unit receives a signal transmitted from a wireless communication terminal device and including a plurality of symbols arranged in a time direction. A scheduling unit estimates the frequency offset based on a first signal that is for measuring quality and that is mapped to a first symbol placed at a predetermined position in the transmitted signals received with the baseband receiving unit, and a second signal that is for demodulation and that is mapped to a second symbol placed at a position different from the first symbol in the transmitted signal.

In a closed-loop wireless communication system, a codebook-based feedback control mechanism is provided where feedback from each of a plurality of receivers is scheduled to control the feedback so that the receiving devices do not needlessly feed back precoding information to the transmitting device. The feedback may be controlled by establishing and distributing a schedule to control when each receiver feeds back precoding information, or by establishing and distributing a metric-based feedback threshold that must be satisfied before feedback is permitted.

Systems and methods are described for scheduling low-delay transmissions from an access node. Packet transmission delay data associated with communication links is received at a base band unit (BBU). The communication links can be routed between pluralities of antennas of the BBU. A link identification can be assigned to each of the communication links and to each antenna in communication with the BBU. A scheduling algorithm in communication with one of the antennas is selected, at the BBU, from a plurality of scheduling algorithms based on the packet transmission delay data associated with at least one of the communication links. Packet data for at least one wireless device may be transmitted using the selected scheduling algorithm.

Provided in the present invention is a method performed by user equipment, and user equipment. The method performed by user equipment is a method, performed by user equipment, for determining address information to which a CSI report belongs or corresponds. The method includes the following steps: carrying, by user equipment, a CSI request trigger in SCI, and scheduling transmission of a PSSCH carrying a TB in the SCI, wherein the TB includes an MAC PDU, and an MAC subheader of the MAC PDU includes address information; receiving, by another user equipment, the SCI, receiving the transmission of the PSSCH according to the information in the SCI, and decoding the TB; and generating, by another user equipment, a CSI report, wherein address information of the CSI report is determined by the address information of the CSI request trigger corresponding to the CSI report.
