Embodiments of the present application can achieve indication of an antenna switching capability for a terminal device with more (such as more than 4) receiving antennas.

Systems, devices, and methods for proportionally balancing power during wireless communication are provided. The disclosures provide for an integrated radio in which the functionality of an active radio and a passive radio are integrated into a single radio, with the active and passive radios each being configured to operate in three different modes: active, passive, and backscatter. Based on power and communication link information, the integrated rode is able to balance the modes at which the two radios are operated, thereby optimizing power consumption of the device into which the integrated radio is incorporated. The resulting systems, devices, and methods lead to ultra-low power consumption that enables these communication techniques to enhance computing devices from smartwatches to laptops. Devices incorporating the integrated radios, and methods for power-proportionally exchanging data, among other systems, devices, and methods, are also provided.

According to an aspect of the present disclosure, there is provided a terminal including: a receiving section configured to receive information giving an instruction on activation or deactivation of a panel; and a control section configured to perform control to perform a communication operation using the panel or a communication operation not using the panel after a certain offset period with reference to at least one of a reception timing of the information and a transmission timing of a delivery confirmation signal for the information.

A method comprising: retrieving a predefined power threshold; determining a transmission power of a transmitting antenna, wherein the transmitting antenna is actively transmitting a signal; retrieving a predefined transmission time interval; determining that the transmission power exceeds the predefined power threshold; determining a duration of transmitting the signal; comparing the duration with the predefined transmission time interval; and switching transmitting the signal from the transmitting antenna to a further antenna when the duration equals the predefined transmission time interval.

Methods, systems, and devices for wireless communications are described to support estimation of a transmission quality imbalance between a set of antennas of a first user equipment (UE). The first UE may use the estimated transmission quality imbalance to determine a transmission diversity scheme that may decrease the transmission quality imbalance. The first UE may determine the transmission quality imbalance between the set of antennas by estimating a reception quality imbalance between the set of antennas. The first UE may estimate the reception quality imbalance for multiple subsets of a time period and may combine the reception quality imbalance estimations for the multiple subsets. The combined reception quality imbalance estimations may represent the transmission quality imbalance between the set of antennas, which may be used to determine a transmission diversity scheme for communicating a transmission to a second UE or a base station.
