Abstract
A wireless device determines that a physical uplink shared channel (PUSCH) duration of an uplink grant of a bundle of a configured uplink grant overlaps with a transmission of a message A (MsgA) payload of a two-step random-access procedure of a cell. Based on the determining, the wireless device ignores the uplink grant by not transmitting via a first PUSCH resource of the uplink grant.
Claims20
A method comprising:
- determining, by a wireless device, that a physical uplink shared channel (PUSCH) duration of an uplink grant of a bundle of a configured uplink grant overlaps with a transmission of a message A (MsgA) payload of a two-step random-access procedure of a cell;
- and
- based on the determining, ignoring the uplink grant by not transmitting via a first PUSCH resource of the uplink grant.
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:
- determine that a physical uplink shared channel (PUSCH) duration of an uplink grant of a bundle of a configured uplink grant overlaps with a transmission of a message A (MsgA) payload of a two-step random-access procedure of a cell;
- and
- based on the determining, ignore the uplink grant by not transmitting via a first PUSCH resource of the uplink grant.
A system comprising:
- a base station;
- and
- 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:
- determine that a physical uplink shared channel (PUSCH) duration of an uplink grant of a bundle of a configured uplink grant overlaps with a transmission of a message A (MsgA) payload of a two-step random-access procedure of a cell;
- and
- based on the determining, ignore the uplink grant by not transmitting, to the base station, via a first PUSCH resource of the uplink grant.
