Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 7:
8. A terminal device, comprising:
a memory for storing computer programs; and
a processor;
wherein the processor is configured to execute the computer programs to:
control a transceiver to detect first Downlink Control Information (DCI) in a Physical Downlink Control Channel (PDCCH) search space corresponding to a first carrier, wherein a first information field in the first DCI indicates a second carrier, the first DCI is scrambled by a first Radio Network Temporary Identifier (RNTI), and the first RNTI is for indicating activation or deactivation of the second carrier; and
activate or deactivate the second carrier in response to the first DCI;
wherein the first DCI comprises a second information field, the second information field is for indicating a configuration parameter of the second carrier, and the configuration parameter of the second carrier comprises: PDCCH Control resource Set (CORESET) configuration, PDCCH search space configuration, Bandwidth Part (BWP) configuration, bandwidth, subcarrier spacing, time domain resource configuration, measurement signal configuration, maximum rank number, antenna port configuration, Hybrid Automatic Repeat reQuest (HARQ) process, and HARQ timing;
wherein in a case where a length of the second information field determined according to a configuration parameter of the first carrier is A, a length of the second information field determined according to the configuration parameter of the second carrier is B, and A is greater than or equal to B, first B bits or last B bits in the second information field are used for indicating the configuration parameter of the second carrier;
wherein in a case where the length of the second information field determined according to the configuration parameter of the first carrier is A, the length of the second information field determined according to the configuration parameter of the second carrier is B, and A is less than B, the configuration parameter of the second carrier indicated by the second information field is a subset of the configuration parameter of the second carrier.
