CPC H04W 76/14 (2018.02) [H04L 1/0003 (2013.01); H04W 4/40 (2018.02); H04W 24/10 (2013.01)] | 20 Claims |
1. A method for transmitting information, comprising:
directly receiving, by at least one first terminal through a direct interconnection communication interface for transmitting Vehicle to Everything (V2X) services, target information sent by a second terminal in a broadcast manner on a target channel;
obtaining, by the at least one first terminal, at least one piece of measurement information respectively, each of the at least one piece of measurement information corresponding to the target information, wherein each of the at least one piece of measurement information comprises a measurement position and one or more measurement values, the measurement position is used to indicate a time-frequency position occupied by the target information, and the one or more measurement values are used to indicate channel quality of the target channel;
transmitting, by the at least one first terminal, the at least one piece of measurement information to the second terminal respectively;
receiving, by the second terminal, the at least one piece of measurement information from the at least one first terminal;
obtaining, by the second terminal, the one or more measurement values comprised in each of the at least one piece of measurement information;
determining, by the second terminal, quality parameter of the target channel used for transmitting the target information according to the one or more measurement values;
determining, by the second terminal, a maximum available Modulation and Coding Scheme (MCS) level corresponding to the target channel according to the quality parameter of the target channel;
selecting, by the second terminal according to a data volume of information to be sent on the target channel, a transport block size (TBS) value, closest to the data volume of the information to be sent, within a range of the maximum available MCS level;
determining, by the second terminal, a number of physical bearers used for transmitting the information to be sent according to the TBS value; and
transmitting, by the second terminal, the information to be sent according to the number of the physical bearers.
