Abstract
The present disclosure presents example techniques for merging multiple concurrent RA procedures. For instance, the present disclosure describes an example method performed by a user equipment, UE (102), for performing random access to connect to a wireless access network. In an aspect the method includes determining that a second RA procedure (122) is triggered during a first RA procedure (120) that is ongoing. In a further aspect, the example includes combining the second RA procedure (122) and the first RA procedure (120). Corresponding UE, computer program, and processor/memory embodiments are also described.
Claims15
A method in a user equipment (UE) for performing random access (RA) to connect to a wireless access network, the method comprising:
- combining a second RA procedure and a first RA procedure responsive to determining that the second RA procedure was triggered while the first RA procedure is ongoing and before a RA response is received for the first RA procedure;
- and
- transmitting a combined RA message for the combined first and second RA procedures at a transmission occasion for the first RA procedure or the second RA procedure.
A user equipment (UE) for performing random access (RA) to connect to a wireless access network, the UE comprising:
- processing circuitry;
- and
- memory storing instructions such that, when executed by the processing circuitry cause the UE to:
- combine a second RA procedure and a first RA procedure responsive to determining that the second RA procedure was triggered while the first RA procedure is ongoing and before a RA response is received for the first RA procedure;
- and
- transmit a combined RA message for the combined first and second RA procedures at a transmission occasion for the first RA procedure or the second RA procedure.
A non-transitory computer readable recording medium storing a computer program product for controlling a user equipment (UE) for performing random access (RA) to connect to a wireless access network, the computer program product comprising software instructions which, when run on processing circuitry of the UE, causes the UE to:
- combine a second RA procedure and a first RA procedure responsive to determining that the second RA procedure was triggered while the first RA procedure is ongoing and before a RA response is received for the first RA procedure;
- and
- transmit a combined RA message for the combined first and second RA procedures at a transmission occasion for the first RA procedure or the second RA procedure.
