Claim of US Patent No. 10,172,154

1. A method for sending control information to ensure that a network is accessed by a terminal, comprising:repeatedly sending, by a first node to the terminal deployed in a low-coverage environment, the control information within a scheduling period for the control information M times,
wherein the scheduling period is a length of N radio frames, N and M are positive integers greater than 1, and N is greater than or equal to M,
wherein repeatedly sending the control information M times comprises:
in the length of N radio frames, sending the control information once on pre-defined resources for sending the control information at a pre-set time interval, or
equally dividing the length of N radio frames into M periods, and sending the control information once on the pre-defined resources for sending the control information in each of M periods;
wherein a system frame number of a radio frame where the pre-defined resources for sending the control information are located is determined by the terminal according to at least one of the followings: a pre-set time interval, a cell identifier and indication signaling;
wherein based on that the system frame number of the radio frame meets a pre-defined condition, the system frame number is the determined system frame number of the radio frame where the pre-defined resources for sending the control information are located, wherein the pre-defined condition comprises one of the followings:
the system frame number % Y=D;
(the system frame number+the cell identifier) % Y=D;
(the system frame number+X) % Y=D; and
(the system frame number+X+the cell identifier) % Y=D,
where % indicates a modulo operation, the pre-set time interval is a length of Y radio frames, wherein Y=N/M, and X is a positive integer determined according to the indication signaling, and D is a natural number pre-defined or determined according to the cell identifier; and
causing the terminal to initiate an access request comprising the control information to access the network.
