摘要： Example signal sending methods and apparatus are described. One example method includes obtaining a first insertion loss corresponding to a first resource and a second insertion loss corresponding to a second resource, where the first insertion loss is different from the second insertion loss. A first transmit power corresponding to the first resource is determined based on the first insertion loss. A second transmit power corresponding to the second resource is determined based on the second insertion loss. A first signal is sent on the first resource based on the first transmit power. A second signal is sent on the second resource based on the second transmit power.

摘要： A method and apparatus for controlling transmit power in a wireless local area network (WLAN). For example, a station may receive, from an access point (AP), a beacon frame that includes a field indicating a maximum transmission power for at least one of a plurality of operational bandwidth that the AP supports. The station may determine a transmission power for a signal to be transmitted to the AP based on the at least one of the plurality of operational bandwidths indicated in the received beacon. The station may then transmit the signal at the determined transmission power.

摘要： A communication device, method and computer program product optimized additional maximum power reduction (A-MPR) during cooperative concurrent uplink transmission. The communication device configures a communications subsystem to perform cooperative concurrent uplink transmissions mode(s). The communications subsystem has transmit chains that include a first transmit chain and a second transmit chain. In response to determining that the first transmit chain has a higher system efficiency level than the second transmit chain, the controller allocates a larger portion of transmit power to the first transmit chain and a smaller portion of the transmit power to the second transmit chain to reduce overall power consumption by the communications subsystem. In response to determining that the first and second transmit chains have an equal efficiency level, the controller allocates equal transmit power to the first and second transmit chains. The controller configures the communications subsystem to communicate an uplink using the allocated power.
