Abstract: A communication method and a device are described to compress and decompress a data packet including an ethernet header to reduce radio transmission resources of an air interface. The communication method includes determining, by a sending device, a to-be-sent data packet. The to-be-sent data packet is a data packet including an ethernet header. The method further includes determining, by the sending device, a field to be compressed in the header of the to-be-sent data packet; and compressing, by the sending device, the header of the to-be-sent data packet according to a preset method. The preset method includes: removing the field to be compressed from the header of the data packet, or replacing the field to be compressed with a corresponding short field; and sending, by the sending device, a data packet obtained after the compressing.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

Abstract: Embodiments of this application provide a communication method and an apparatus. A correspondence between a plurality of MCS indexes and a plurality of modulation schemes is provided to achieve flexible selection of a modulation scheme. In the correspondence, at least one MCS index of the plurality of MCS indexes corresponds to a set modulation schemes which comprises π/2 binary phase shift keying (π/2-BPSK) modulation and quadrature phase shift keying (QPSK) modulation. A first communication device receives a target modulation and coding scheme (MCS) index from a second communication device, determines a target modulation scheme corresponding to the target index number based on the correspondence, and performs communication with the second communication device based on the target modulation scheme.
