Secondary cell state indication method and communication device

A Secondary Cell (SCell) state indication method for a User Equipment (UE), comprising:

• receiving a state transition indication information transmitted by a network side device, the state transition indication information being used to indicate an SCell state transition between two of an activated state, a deactivated state and a third state;
• and
• transiting the state of the SCell in accordance with the state transition indication information,
• wherein the state transition indication information is first information, the first information comprises a Media Access Control (MAC) Control Element (CE) of N bits, where N is a positive integer;
• the MAC CE comprises M SCell sequence bits Ci, where M is a positive integer, and i is an integer smaller than or equal to M;
• a value of Ci is used to indicate the state transition of the SCell corresponding to Ci between two of the activated state, the deactivated state and the third state;
• or
• the state transition indication information is second information, the second information comprises an MAC CE and a field L indicating a length of the MAC CE;
• the MAC CE comprises at least two fields, and each field comprises N bits, where N is a positive integer;
• wherein each field of the MAC CE comprises M SCell sequence bits Ci, where M is a positive integer, and i is an integer smaller than or equal to M;
• a value of Ci in each field is used to indicate the state transition of the SCell corresponding to Ci between two of the activated state, the deactivated state and the third state;
• or
• the state transition indication information is third information, the third information comprises an LCID and an MAC CE of N bits, where N is a positive integer;
• the MAC CE comprises a field of M groups of SCell sequence bits Ci, and a field of each group of Ci comprises X bits, where M is a positive integer, X is a positive integer greater than 1, and i is an integer smaller than or equal to M;
• a value of the LCID and a value of the X bits in the field of each group of Ci are used to indicate the state of the SCell corresponding to Ci to be transited into one of the activated state, the deactivated state and the third state.
