Described embodiments provide systems and methods for adjusting a radio usage of a wireless link according to a time-averaged specific absorption rate (SAR). A first device configured to concurrently maintain a first wireless link with a second device and a second wireless link with an access point of a network may determine a proposed radio usage of the first wireless link and the second wireless link. The first device may determine a state of the first device according to the proposed radio usage and sensor information from at least one sensor of the first device. The first device may determine a time-averaged SAR of a user due to the first device, according to a defined time window and the determined state of the first device, to adjust the proposed radio usage of the first wireless link and the second wireless link to satisfy a threshold level of the time-averaged SAR.

Methods and systems are provided for deploying a cellular communication network, including basestation systems. A basestation system may include a plurality of femtocells including at least a first femtocell and a second femtocell, with the first femtocell being operable to support an operation in a coverage area corresponding to the second femtocell. A first transmission within the coverage area from the first femtocell may be coordinated with a second transmission within the coverage area from the second femtocell. The plurality of femtocells may further include a third femtocell, and a first reception by the first femtocell may be coordinated with a second reception by the third femtocell. The transmissions and/or receptions may be coordinated in one or more of time, power, and frequency.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for requesting message repetition in random access procedures. In some aspects, a first random access message can be generated for a physical random access channel (PRACH) procedure. The first random access message can include a request for repetition of a third random access message. The request can be based on a criterion that is associated with at least one of a maximum allowed transmit power, or a PRACH transmit power. The first random access message can be output for transmission to a node to initiate a random access procedure with the node. In some aspects, one or more parameters related to a threshold for determining whether to include the request can be configured by the node.

Aspects of the subject disclosure may include, for example, detecting a first wireless signal associated with a first communication device that interferes with a second wireless signal associated with a second communication device. Further embodiments include identifying a first frequency band in which the first wireless signal is assigned, the first frequency band associated with a first mobile network, and identifying a second frequency band in which the second wireless signal is assigned, the second frequency band associated with a second mobile network. Additional embodiments can include detecting the first wireless signal is above a first power threshold, and providing instructions to a base station associated with the first communication device. The instructions indicate the base station to assign first wireless signal associated with the first communication device from the first frequency band to a third frequency band associated with the first mobile network. Other embodiments are disclosed.

Methods, systems, and devices for wireless communications are described. A base station may communicate with a user equipment (UE) or multiple UEs using multicast transmissions, and each of the multiple UEs may use shared resources to transmit feedback. A UE may receive a power control configuration associated with multicast communications and indicating one or more control parameters or weighting factors for uplink feedback. The UE may monitor a set of downlink resources for the multicast message from the base station, and may determine a decoding failure for the multicast message. The UE may determine whether to transmit uplink feedback to the base station based on the received power control parameters, such as adjusting UE transmit power using a weighting factor or other power control parameters. The UE may determine whether to transmit the uplink feedback message indicating the decoding failure based on the power control configuration.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE, wherein the virtual port is a combination of two or more antenna ports. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

A roaming method based on MESH WIFI executable by an electronic device, comprising: calculating noise values and interference coefficients of a primary access point (AP) and surrounding APs, adjusting power values between the primary AP and the surrounding APs based on the noise values and the interference coefficients according to normalization, and, when a target AP from the surrounding APs reaches a preset condition, switching the client to connect to the target AP.

The disclosed technology provides a system and method for allocating resource blocks to a wireless device based on a power headroom of the wireless device as contained in a power headroom report (PHR) from the wireless device. The network allocates wireless devices with the highest power headroom (e.g., power headroom above a certain power threshold) with edge resource blocks, wireless devices with the lowest power headroom (e.g. power headroom below a certain power threshold) with inner resource blocks, and other wireless devices with outer resource blocks.
