A resource allocation method for controlling, by a base station, inter-cell interference in a wireless communication system operating in a flexible duplex mode on a cell-by-cell basis may comprise the steps of: receiving, from an adjacent base station, information on a resource for downlink only, allocated to an adjacent cell to which the adjacent base station belongs, in a predetermined subframe; and allocating, to terminals in a cell to which the base station belongs, a resource for the cell, which corresponds to the resource for downlink only, allocated to the adjacent cell, as a resource for downlink only, on the basis of the information on the resource.

The present disclosure provides a signal transmission method and a signal transmission device. The signal transmission method includes: transmitting a first reference signal, the first reference signal indicating that the first network device is subjected to remote interference; and receiving a second reference signal, the second reference signal indicating that there is the remote interference and/or atmospheric ducting phenomenon.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, obtaining uplink information associated with a downlink path, wherein the uplink information includes operational parameters used by a plurality of communication devices for transmitting wireless signals on a plurality of uplink paths; performing, based on the uplink information, a plurality of measurements of the plurality of uplink paths; identifying a measurement from the plurality of measurements that is below a threshold, thereby indicating an affected uplink path of the plurality of uplink paths; initiating a first filtering of the affected uplink path, wherein the initiating is based on the identifying and wherein the first filtering is based upon one or more first filtering parameters; and receiving instructions comprising one or more updated filtering parameters, wherein the instructions are received by the system at a port of the system. Other embodiments are disclosed.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, obtaining uplink information that describes a configuration for uplink wireless communications by a communication device, wherein the uplink information comprises a first assignment of a first resource block to the communication device for transport of control information as a physical uplink control channel (PUCCH); performing a first Signal to Interference plus Noise Ratio (SINR) measurement of the PUCCH; initiating a first corrective action responsive to detecting the first SINR measurement being below a first SINR threshold; and initiating a second SINR measurement of the PUCCH to confirm the second SINR measurement is above the first SINR measurement. Other embodiments are disclosed.

An information receiving method, an information sending method, and a device are provided. Under these methods, a timing adjustment amount can be determined by a first access network device. The timing adjustment amount is an adjustment amount between a first timing at which the first access network device sends a first downlink signal to a first terminal device on a first frequency band and a second timing at which the first access network device sends a second downlink signal to the first terminal device on a second frequency band. The first frequency band and the second frequency band are paired frequency bands. First indication information can be sent, by the first access network device, to the first terminal device. The first indication information indicates the timing adjustment amount.

Method, systems and devices for identifying and mitigating remote interference, e.g. a downlink transmission from a remote network device interfering with uplink transmissions of another network device, are described. One example method for identifying remote interference includes determining that an interference type is a remote interference, and transmitting, in response to the determining, a reference signal indicative of a resource that was affected by the remote interference. Another example method for identifying remote interference includes detecting a reference signal in a frame, and determining a resource that was affected by a remote interference based on a position of the reference signal in the frame.

Techniques are described for configuring resources for remote interference mitigation (RIM). An example method includes configuring a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information. The method also includes configuring a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, where the RS is transmitted in response to determining an interference and based on the configured first sequence or second sequence.

Systems and methods for mitigation of cross channel interference are disclosed in which the TDD configuration of a potential cross channel interference source is detected by received signals within the network with which the source interferes. The TDD configuration is then used to synchronize the transmissions from the network with which the source interferes to reduce the interference. In addition, interference is mitigated by providing adaptive guard bands based on results of a radio frequency environmental survey and/or coaxing an interfering user to another channel. Sub-channels can be assigned based on the results of the radio frequency environmental survey and Quality of Service requirements for traffic flows.

A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station. The UE may transmit information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station may be scheduled based at least in part on the RTD between the first base station and the second base station. Numerous other aspects are provided.
