20220209926 · 2022-06-30 ·

A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.

Spatial reuse in WLAN multi-AP network

Systems and methods of WLAN communication including efficient spatial reuse mechanisms for relay transmissions between a repeater network and non-AP STAs in OFDMA. The non-AP STAs are grouped based on their connectivity with the individual repeaters and the radio coverage regions of the repeaters. Each group is either a non-overlapping group with the constituent non-AP STAs located in a non-overlapping coverage region of a particular repeater, or an overlapping group with the constituent non-AP STAs located in an overlapping coverage region of two or more repeaters. Based on the grouping, certain RUs (or subchannels) are reused for multiple groups without causing inter-group interference, thereby expanding the bandwidths used in the relay operations. RU allocation based on grouping can be used in combination with transmit power adjustment to achieve efficient spatial reuse in OFDMA.

Interference coordination region configuration

Methods, systems, and devices for wireless communications are described. In some systems implementing beamforming, a neighboring base station may cause interference to a user equipment (UE) served by a different base station. To mitigate unexpected interference, an interference coordination region including time and frequency resources may be configured between the base stations. The interference coordination region may be configured based on long-term information for the base stations and may include one or both of a set of beam-avoidance sub-regions or a set of beam-preference sub-regions for a base station, where each sub-region is associated with a beam index. A base station may schedule a communication beam in the interference coordination region based on a beam-avoidance region (e.g., refraining from using a particular communication beam) or a beam-preference region (e.g., prioritizing a particular communication beam). The base station may transmit a message to a UE using the scheduled communication beam.

Method and network node for reducing interference in a wireless network

A method and a network node (700) serving a first cell in a wireless network, for reducing interference in a second cell caused by transmission of reference signals in the first cell. The network node (700) transmits (7:2) in the first cell a scheduling block where a number of said reference signals are located in predefined resource element positions in the scheduling block, using a time offset relative transmission of a scheduling block in the second cell. Thereby, the impact of interference from a reference signal from one network node will be distributed over several resource elements in the other network node so that the impact in each resource element is reduced, as compared to when all interference from the reference signal hits one single resource element when no time offset is used.
