Claim of US Patent No. 10,433,341

1. A method for sending a Random Access Response, RAR, message, comprising:sending, by a first type node, an RAR message through a downlink channel, wherein the RAR carries one or more pieces of RAR information of a second type node;
wherein the RAR information of the second type node comprises resource allocation information required for the second type node to send a Msg3 message; and
wherein position information of a band occupied by sending the Msg3 message through the second type node is determined by at least one of the following manners:
determining in a pre-defined manner,
indicating in the RAR information of the second type node,
occupying a same band as a random access signaling sent by the second type node, and
determining by a band occupied by the random access signaling sent by the second type node; the method further comprising: containing scheduling information of the RAR in Downlink Control Information, DCI, and sending the scheduling information of the RAR through a Physical Downlink Control Channel, PDCCH, and/or an Enhanced PDCCH, EPDCCH, wherein
the scheduling information of the RAR comprises resource allocation information about RAR information of N levels of second type nodes in the RAR, and N is greater than or equal to 1;
and
wherein the resource allocation information is indicated by first index information, and the first index information is expressed by K bits, wherein K is greater than or equal to 1; and
any one or more pieces of the following information are indicated through the first index information:
level quantity information of the second type nodes to which RAR information sent in the RAR belongs,
level index information of the second type nodes to which RAR information sent in the RAR belongs,
quantity information of RAR information supported and sent to each level of second type node in the RAR, and
ratio information of the quantity of RAR information supported and sent to each level of second type node in the RAR to a quantity of RAR information that can be totally supported in the RAR.
