Abstract: A method for a terminal to transmit an uplink signal is provided. The method includes: receiving an instruction sent by a serving base station and used for determining transmit power; selecting an uplink power control formula from a plurality of uplink power control formulas according to the instruction; obtaining transmit power of an uplink signal by using the selected uplink power control formula; and transmitting an uplink signal by using the transmit power. According to the application, a terminal is not only capable of selecting, according to a receiving manner, an associated uplink power control formula to determine a transmit signal, but also capable of using the uplink power control formula for a different configuration parameter of a non-periodical SRS to determine suitable transmit power to transmit an uplink signal.

Abstract: Embodiments of the present invention provide a detecting method, a transmitting method and an apparatus for a common control channel. The detecting method includes: determining a candidate resource set within virtual downlink resources of a current cell. The candidate resource set can include at least one candidate resource carrying a common control channel of the current cell. A detection is performed on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell. In the embodiments of the present invention, a selection range of resources for transmitting a common control channel is extended, so that inter-cell interference of the common control channel can be coordinated, and a detection performance of the common control channel can be improved.

Abstract: A data transmission method and a communications device resolve an existing problem that use of an unlicensed spectrum is interfered with between LTE devices when a padding is sent. The method includes: performing, by a communications device, CCA on an unlicensed spectrum; and when determining that the unlicensed spectrum is in an idle state, sending, by the communications device on a preset band resource in the unlicensed spectrum, a signal indicating that the communications device uses the unlicensed spectrum, where the preset band resource is a partial band resource in the unlicensed spectrum. Mutual interference between communications devices when the unlicensed spectrum is used is eliminated.
