Abstract
Wireless communications for random access procedures are described. A wireless device may send one or more messages as part of a random access procedure. The wireless may re-send a first message of the one or more messages a redundancy value equal to zero if the random access procedure is a two-step random access procedure. The wireless may re-send the first message of the one or more messages the redundancy value equal to zero if the wireless device falls back to a four-step random access procedure.
Claims20
A method comprising:
- sending, by a wireless device, a first transmission associated with a random access procedure, wherein the first transmission comprises:
- a preamble;
- and
- a transport block comprising a first redundancy version;
- and
- based on a determination that a random access response associated with the transport block has not been received, resending the transport block with the first redundancy version.
A method comprising:
- receiving, by a wireless device, one or more messages comprising one or more configuration parameters for a cell, wherein the one or more configuration parameters indicate a redundancy version sequence;
- sending a first transmission associated with a random access procedure, wherein the first transmission comprises:
- a preamble;
- and
- a transport block comprising a first redundancy version of the redundancy version sequence;
- and
- based on a determination that a random access response corresponding to the transport block has not been received, resending the transport block with a second redundancy version of the redundancy version sequence.
A method comprising:
- receiving, by a wireless device, one or more messages comprising one or more configuration parameters, wherein the one or more configuration parameters indicate a redundancy version sequence;
- sending a transport block comprising a first redundancy version of the redundancy version sequence;
- and
- based on a determination that a random access response corresponding to the transport block has not been received, resending the transport block with the first redundancy version.
