[Solution] Provided is a communication control apparatus including: a calculation unit configured to calculate a transmit power to be allocated, including a nominal transmit power and a margin for interference avoidance, for one or more secondary systems that secondarily use frequency channels protected for a primary system; and a determination unit configured to determine a variation in a number of secondary systems, and cause the calculation unit to adjust the margin for interference avoidance on a basis of the determined variation.

Embodiments of the present invention relate to the technical field of communications, and provide an interference processing method, apparatus and system, for use in solving the problem that interference exists between base stations. The specific solution included: a target device receives interference information sent by a first base station, the interference information being used for indicating an interference parameter when the first base station is interfered by a second base station, the target device being the second base station or an interference management device; and the target device determines a processing mode of the interference according to the interference parameter. The embodiments of the present invention are applied to a process of a processing mode of the interference between the base stations.

Certain aspects of the present disclosure provide techniques for remote interference determination at a first base station based on assistance from one or more neighboring base stations of the first base station. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving from a second BS neighboring the first BS an uplink interference report request. The method further includes transmitting to the second BS an uplink interference report in response to the uplink interference report request, the uplink interference report comprising information indicative of uplink interference caused by one or more user equipments communicating on an uplink with the first BS.

Inter-protocol interference reduction for hidden nodes may be provided. A first service end point may determine that an inter-protocol interference is present on a channel. Next, an initial packet failure count value on the channel may be determined. A transmit (Tx) power for selected packets may then be increased until a subsequent packet failure count value on the channel is less than the initial packet failure count value.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station serving the UE in a first network, a power control configuration and a reference signal measurement configuration. The UE may receive, based at least in part on the reference signal measurement configuration, a reference signal from at least one wireless device of a second network. The UE may determine, based at least in part on the power control configuration and the received reference signal, an interference level for the second network introduced by the first network. The UE may adjust a transmission power limit for the UE based at least in part on the determined interference level and the power control configuration. The UE may transmit signals to the base station according to the adjusted transmission power limit.

A user equipment (UE) is configured by a Master enhanced NodeB (MeNB) for operation with dual connectivity to a Secondary eNB (SeNB) to transmit acknowledgement information when the UE is power limited and for a respective eNB to determine a UE power limitation. The UE, the MeNB, and the SeNB adjust operation according to a partitioning of a UE capability between the MeNB and the SeNB. The UE capability can be a transmission power, a soft buffer size, a reception or a transmission of a number of data transport block bits, or a number of decoding operations.

A radio node may transmit a signal using a transmit power. Then, the radio node may adjust the transmit power within a range of values. The adjustment may include reducing the transmit power when a spatial received signal strength indication (RSSI) metric of the radio node is greater than a first threshold value and a coverage criterion is met. Note that the spatial RSSI metric of the radio node may correspond to a set of temporal RSSI metrics of the radio node received from neighboring radio nodes. Moreover, the coverage criterion may be that less than a portion of RSSI measurements of the radio node associated with electronic devices, which are communicatively attached with the radio node, is less than a second threshold value. Alternatively, the adjustment may include increasing the transmit power when the spatial RSSI metric is less than the first threshold value.
