Abstract
A communication method, a network side device, and a terminal are provided. In the method, a network side device selects one group of values from at least two preset groups of values for a transmission parameter set; the network side device sends the selected group of values; and a terminal sends communication data based on the group of values of the at least two groups of values of the transmission parameter set. The present invention can adapt to different system statuses and service requirements, thereby improving transmission performance.
Claims8
A communication method, comprising:
- obtaining, by a network side device, sidelink congestion information;
- selecting, by the network side device, a value of transmission power from at least two preset values of transmission power according to the sidelink congestion information;
- selecting, by the network side device, a value of number of retransmissions from at least two preset values of number of retransmissions according to the sidelink congestion information;
- selecting, by the network side device, a value of modulation and coding scheme (MCS) level from at least two preset values of MCS level according to the sidelink congestion information;
- and
- sending, by the network side device via control signaling, the selected values of transmission power, retransmission number, and MCS level to a terminal for configuring sidelink communication of the terminal.
A communication method, comprising:
- measuring, by a terminal, a status of a sidelink;
