Abstract

The invention discloses an information sending and receiving method and a device. The method comprises the steps that terminal equipment receives indication information from network equipment, whereinthe indication information indicates a timing adjustment parameter; the timing adjustment parameter is used for the terminal device to determine sending timing on a first uplink carrier and a seconduplink carrier, the first uplink carrier is an uplink carrier of a first wireless access technology, the second uplink carrier is an uplink carrier of a second wireless access technology, and the terminal device determines the timing adjustment parameter according to the indication information. In the method of the invention, the terminal equipment is used for determining the sending timings on the plurality of uplink carriers through the timing adjustment parameter sent by the network equipment, so that the terminal equipment is ensured to maintain the same sending timing on the plurality ofuplink carriers, uplink resources can be effectively utilized, and resource waste is avoided.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for sending and receiving information. Background technique [0002] In the wireless communication system, according to the different types of sending nodes and receiving nodes, communication can be divided into different types. Generally, sending information from a network device to a terminal device is called downlink communication, and sending information from a terminal device to a network device is called uplink communication. In the long term evolution (long term evolution, LTE) / long term evolution advanced (long term evolution advanced, LTE-A) communication system, it can be divided into frequency division duplex (frequency division duplex, FDD) mode and Time division duplex (time division duplex, TDD) mode. [0003] For a wireless communication system operating in TDD mode, the downlink carrier and the uplink carrier are ...
