Random access signalling resending method and apparatus
First Claim
Patent Images
1. A method for resending random access signaling, comprising:
- under the circumstance that a first condition is met, resending, by a second-type node, random access signaling Message 1 (Msg1), wherein the first condition comprises at least one of that;
the second-type node fails to successfully decode a Random Access Response (RAR) Msg2;
the second-type node successfully decodes the RAR Msg2, and there is no RAR information, which is intended to be sent to the second-type node, in the decoded RAR Msg2;
a first-type node fails to successfully decode a Msg3;
the first-type node successfully decodes the Msg3, and sends a Msg4 to the second-type node, and the second-type node fails to successfully decode the Msg4; and
the first-type node successfully decodes the Msg3, and sends the Msg4 to the second-type node, the second-type node successfully decodes the Msg4 and finds that the Msg4 is not intended to be sent to the second-type node.

Abstract
Provided are a random access signalling resending method and apparatus. In the method, in the case where a first condition is satisfied, a second-type node is adopted to resend random access signalling Msg1, thereby solving the problem that the access quality of a user terminal accessing an LTE/LTE-A system is not high and improving the access quality of the user terminal accessing the LTE/LTE-A system.

22. A device for resending random access signaling, comprising:
-
a processor; and a memory configured to store instructions executable by the processor, wherein the processor is configured to; detect whether a first condition is met or not, wherein the first condition comprises at least one of that; a second-type node fails to successfully decode a Random Access Response (RAR) Message 2 (Msg2); the second-type node successfully decodes the RAR Msg2, and there is no RAR information, which is intended to be sent to the second-type node, in the decoded RAR Msg2; a first-type node fails to successfully decode a Msg3; the first-type node successfully decodes the Msg3, and sends a Msg4 to the second-type node, and the second-type node fails to successfully decode the Msg4; the first-type node successfully decodes the Msg3, and sends the Msg4 to the second-type node, the second-type node successfully decodes the Msg4, and finds that the Msg4 is not intended to be sent to the second-type node; and under the circumstance that the first condition is met, resend, by the second-type node, random access signaling Msg1. - View Dependent Claims (23, 25, 33, 35, 36, 37, 38, 39)
