## Abstract

According to the present invention, a method performed by user equipment (UE) is provided, comprising: receiving dynamic uplink grant for a medium access control (MAC) entity; determining, for the received dynamic uplink grant, whether a first configuration condition is satisfied; and if the first configuration condition is satisfied, delivering the uplink dynamic grant to a hybrid automatic repeat request (HARQ) entity.

## Claims

### Claim 1

A method performed by a user equipment (UE), comprising:
receiving a radio resource control (RRC) message which contains an enable prioritization indication used to indicate that the UE is configured with prioritization between overlapping uplink grants based on a Logical Channel priority; and
for each Serving Cell and each activated configured uplink grant,
in a case that the enable prioritization indication is configured to the UE and a physical uplink shared channel (PUSCH) duration of the activated configured uplink grant does not overlap with a PUSCH duration of an uplink grant received in a Random Access Response for the Serving Cell,
setting a hybrid automatic repeat request (HARQ) Process identifier (ID) to the HARQ Process ID associated with the PUSCH duration of the activated configured uplink grant.

### Claim 2

A user equipment (UE), comprising:
receiver circuitry configured to receive a radio resource control (RRC) message which contains an enable prioritization indication used to indicate that the UE is configured with prioritization between overlapping uplink grants based on a Logical Channel priority; and
controller circuitry configured to perform:
for each Serving Cell and each activated configured uplink grant,
in a case that the enable prioritization indication is configured to the UE and a physical uplink shared channel (PUSCH) duration of the activated configured uplink grant does not overlap with a PUSCH duration of an uplink grant received in a Random Access Response for the Serving Cell,
setting a hybrid automatic repeat request (HARQ) Process identifier (ID) to the HARQ Process ID associated with the PUSCH duration of the activated configured uplink grant.
