Claim 0:
1. A method, comprising:
receiving, by a terminal device, configuration parameters for downlink control channel monitoring according to a first time pattern and a second time pattern;
performing, by the terminal device, the downlink control channel monitoring according to the first time pattern, wherein the downlink control channel monitoring is performed on an unlicensed band;
determining that data has been transmitted on the downlink on a number of symbols, wherein the determination that the data is transmitted is based on detecting downlink control information intended for a group of terminal devices;
based on the determination that the data is transmitted, suspending the performing of the downlink control channel monitoring according to the first time pattern;
performing downlink control channel monitoring according to the second time pattern on at least a next symbol after transmission of the data;
performing downlink control channel monitoring according to the second time pattern at least for one next slot after the end of the transmission of the data, wherein the first time pattern has more than one downlink control channel monitoring occasion per slot and a second time pattern follows slot periodicity of 2 symbols or 14 symbols;
determining, by the terminal device, that downlink transmission has ended; and
based on the determination that the downlink transmission has ended, suspending the downlink control channel monitoring according to the second time pattern.
