Abstract
A wireless device transmits preambles at different times. After each transmission of a preamble in the preambles and at least until a transmission of a last preamble in the preambles monitoring, a control channel is monitored for random access responses (RARs) identified by random access radio network temporary identifiers (RA-RNTIs) that each correspond to one of the transmitted preambles. A packet is transmitted based on receiving a first RAR of the RARs.
Claims20
A method comprising:
- consecutively transmitting, by a wireless device, a plurality of preambles at different times;
- monitoring, after transmitting a first preamble in the plurality of preambles and at least until a transmission of a last preamble in the plurality of preambles, a control channel for a plurality of random access responses (RARs) identified by random access radio network temporary identifiers (RA-RNTIs), wherein each of the RA-RNTIs corresponds to one of the transmitted preambles;
- and
- transmitting a packet based on receiving a first RAR of the RARs.
1 more element
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- consecutively transmit a plurality of preambles at different times;
- monitor, after transmitting a first preamble in the plurality of preambles and at least until a transmission of a last preamble in the plurality of preambles, a control channel for a plurality of random access responses (RARs) identified by random access radio network temporary identifiers (RA-RNTIs), wherein each of the RA-RNTIs corresponds to one of the transmitted preambles;
- and
- transmit a packet based on receiving a first RAR of the RARs.
