Aspects of the subject disclosure may include, for example, segmenting an assigned spectrum into a lower portion, a middle portion, and an upper portion, establishing one or more full power wireless connections in the middle portion of the assigned spectrum, and establishing one or more reduced power wireless connections in the upper and lower portions of the assigned spectrum. Other embodiments are disclosed.

Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive, a downlink control signal indicating that an uplink control signal is to be transmitted using two or more transmission beams during different transmission time intervals (TTIs). The UE may identify the two or more transmission beams based at least in part on the downlink control signal, and may transmit a plurality of repetitions of an uplink signal on the two or more transmissions beams. Each repetition may be transmitted on a different TTI using a different one of the two or more transmission beams based at least in part on the downlink control signal.

A wireless communication apparatus supports a first scheme and a second scheme. A communication range for the second scheme is narrower than a communication range for the first scheme. Processing circuitry of the apparatus is configured to set first information and second information. If the second scheme is used, the processing circuitry sets a second level greater than a first level for the second information and sets a second power value smaller than a first power value for the first information. The first level and the first power value are used for the first scheme. The second power value is decided based on a receiving sensitivity required for a physical scheme selected by the second scheme.

A data transmission method includes obtaining, by user equipment (UE), a maximum transmit power; determining, by the UE, a transmit power of a data channel and/or a transmit power of a control channel based on the maximum transmit power and a first parameter, where the first parameter includes at least one of the following: a bandwidth of the data channel, a bandwidth of the control channel, or a carrier type of a carrier of a first link; and sending, by the UE, the control channel and the data channel in a same subframe.

A power transmission apparatus has a first communication function for communicating with a power reception apparatus and a second communication function for communicating with the power reception apparatus at a radio frequency different from a radio frequency used in the first communication function, and makes a decision as to whether to use the first communication function or the second communication function in communication for controlling wireless transmission of power, the decision being made on the basis of device information obtained from the power reception apparatus through communication using the first communication function.

This application provides a multi-air-interface communication method and an apparatus. In the method, a mobile terminal supports a plurality of types of air interfaces. The method resolves a BSR sending problem, a PHR reporting problem, and a DRX problem in a case of a plurality of air interfaces. The method that resolves the BSR sending problem in the case of the plurality of air interfaces enables a base station to more accurately allocate a radio resource to the mobile terminal based on a BSR sent on each air interface by the mobile terminal. The method that resolves the PHR reporting problem in the case of the plurality of air interfaces enables the base station to more accurately allocate the radio resource to the mobile terminal. The method that resolves the DRX problem in the case of the plurality of air interfaces is more beneficial to power saving of the mobile terminal.
