A power control method and a communications apparatus, in which the method includes: obtaining, by a terminal device, slot format information (SFI) of a target slot in a non-serving cell; and determining, by the terminal device based on the SFI, a power control parameter set used by the terminal device to send data in the target slot in a serving cell, where the power control parameter set belongs to a set of power control parameter sets configured for the terminal device. According to the power control method provided in this application, when a time domain resource conflict exists between the serving cell and the non-serving cell of the terminal device, the terminal device may determine an uplink power control parameter set of the serving cell of the terminal device by using the obtained SFI that dynamically changes in the non-serving cell.

Methods, systems, computer-readable media, and apparatuses for to managing use of a satellite positions system (SPS) receiver in conjunction with one or more radio access technology (RAT) transmitters. In certain embodiments, a controller can be used to prioritize reception by the SPS receiver over transmission by the one or more RAT transmitters.

Techniques for adjacent channel interference mitigation are described. In one embodiment, for example, a user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to associate the UE with a pico evolved node B (eNB) in a time-division duplex (TDD) picocell, identify an incongruent uplink (UL) sub-frame for the picocell, and select an enhanced UL transmit power for the incongruent UL sub-frame. Other embodiments are described and claimed.

Techniques for dynamically determining coverage area and data throughput in a heterogeneous network are discussed herein. In some examples, a base station can use frequency resources from a Citizens Broadband Radio Service band provided that such use does not cause harmful interference for incumbent users. For example, to avoid interfering with an incumbent device while maintaining transmission, an algorithm may be deployed to dynamically determine data throughput for the base station and connected user equipment based on interference level and traffic type. The base station can receive interference information with uplink feedback from the user equipment. Interference information can also be used to configure the base station to dynamically adjust its data coverage area, for example, by varying a transmission power. As the conditions at a base station change over time (e.g., hourly, daily, weekly, etc.), data coverage area can be reconfigured at the base station.

Device-to-device (D2D) transmissions by a wireless device may interfere with base station reception of other signals. To mitigate this interference, the wireless device estimates the path loss between itself and the base station. The path loss and the current D2D transmission power level are used to estimate the amount of interference the base station is experiencing as a result of the D2D transmissions from the wireless device. Based on the estimated interference experienced by the base station, the wireless device increases the robustness of the MCS being used and decreases the transmission power level by a corresponding amount. By decreasing the D2D transmission power level, less interference will be experienced by the base station. By increasing the robustness of the MCS, the impact of the reduced D2D transmission power level is mitigated.

Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement push-to-talk type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

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.

User equipment includes an antenna, a controller, a transmitter, and a receiver. The transmitter sends a first radio frequency signal for communication with a primary cell to the antenna according to a first timing advance set by the controller, and sends a second radio frequency signal for communication with a secondary cell to the antenna according to a second timing advance set by the controller. The receiver sends received data to the controller including information regarding at least one of the first timing advance and the second timing advance. The first timing advance indicating a first uplink transmission timing alignment value and the second timing advance indicating a second uplink transmission timing alignment value.
