Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A system, comprising:
at least one first terminal; and
a second terminal,
wherein the at least one first terminal is configured to:
directly receive, through a direct interconnection communication interface for transmitting Vehicle to Everything (V2X) services, target information sent by the second terminal in a broadcast manner on a target channel;
obtain 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 includes 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; and
transmit the at least one piece of measurement information to the second terminal respectively;
wherein the second terminal is configured to:
receive the at least one piece of measurement information from the at least one first terminal;
obtain the one or more measurement values comprised in each of the at least one piece of measurement information;
determine quality parameter of the target channel used for transmitting the target information according to the one or more measurement values;
determine a maximum available Modulation and Coding Scheme (MCS) level corresponding to the target channel according to the quality parameter of the target channel;
select, 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;
determine a number of physical bearers used for transmitting the information to be sent according to the TBS value; and
transmit the information to be sent according to the number of the physical bearers.
