Abstract
The document discloses a method for sending a Random Access Response (RAR) message and a node. The method includes: a first type node sends an RAR through a downlink channel, and the RAR carries one or more pieces of RAR information of a second type node.
Claims19
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.

A node, comprising:
- a response message sending module configured to, send a Random Access Response, RAR, 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 response message sending module is further configured to:
- contain scheduling information of the RAR in Downlink Control Information, DCI, and send 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
- 1;
- 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.
