Abstract
The invention relates to a method of and an apparatus for processing a random access response, the method comprising the steps of: transmitting a random access preamble; receiving a random access response within a random access response time window; checking an extension field flag of the random access response; checking if the random access response matches the random access preamble; wherein if the random access response does not match the random access preamble and if the extension field flag is set to zero, the random access response reception is considered as unsuccessful and a further random access preamble is transmitted.
Claims8
A method of processing a random access response, the method comprising:
- transmitting a random access preamble;
- receiving a random access response within a random access response time window, the random access response comprising a random access identifier (ID) and an extension field flag;
- checking the random access identifier and the extension field flag of the random access response;
- and
- deeming a reception of the random access response as unsuccessful and retransmitting the random access preamble if the random access identifier does not match the random access preamble and the extension field flag is set to zero.
A User Equipment, comprising:
- a transceiver configured to transmit a random access preamble and to receive a random access response, the random access response received within a random access response time window and comprising a random access identifier (ID) and an extension field flag;
- and
- a processor configured to:
- check the random access identifier and the extension field flag of the random access response;
- and
- deem a reception of the random access response as unsuccessful and retransmit the random access preamble if the random access identifier does not match the random access preamble and the extension field flag is set to zero.
