Abstract

The embodiment of the invention discloses a method and a device for transmitting a system message and relates to the field of communication. After a relay function is started, a relay can normally receive system configuration information of a relay link, and the normal transmission of the relay link is guaranteed so as to guarantee the normal operation of the system. The method comprises the following steps of: mapping the system message of the relay link to a relay link physical downlink shared channel; transmitting the relay link physical downlink shared channel to the relay; and transmitting a relay link physical downlink control channel to the relay, wherein the relay link physical downlink control channel carries indication information of a time-frequency resource position of the relay link physical downlink shared channel. The method is mainly used in the process of transmitting the system message after the relay is introduced into a network and the relay function is started.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for transmitting system messages. Background technique [0002] In order to continuously improve system performance, LTE-A (Long Term Evolution-Advance, long-term evolution follow-up technology) introduces Relay (relay station) technology on the basis of LTE. After the introduction of Relay, the one-hop link from the eNodeB (base station) to the terminal in the original LTE system becomes a two-hop link from the eNodeB to the Relay and from the Relay to the terminal. Relay link, Relay to terminal is an access link. [0003] In the traditional transmission mode, the eNodeB directly sends system messages to the terminals it serves. In the LTE system, the eNodeB modifies the system information at the boundary of the modification period, and transmits the modified system information to the terminal in a periodic broadcast mode. [0004] In the prior art, after introdu...
