Mobile communication method and radio base station

摘要

A mobile communication method includes step for transmitting a first scheduling grant information to a first mobile station UE scheduled in a current scheduling assignment slot, and transmitting a second scheduling grant information to a second mobile station UE to be scheduled in a next TTI by the radio base station Node B at a time of switching between mobile stations UE to be scheduled, the first scheduling grant information instructing to stop transmission of a MAC-e PDU in a next transmission time interval, the first scheduling grant information corresponding to a minimum size of the MAC-e PDU which can contain only one MAC-d PDU.

1. A mobile communication method in which a mobile station transmits Media Access Control-layer e Protocol Data Unit (MAC-e PDU) containing one or more Media Access Control-layer d Protocol Data Units (MAC-d PDUs) with a fixed size to a radio base station via a high-speed uplink data channel, the method comprising the steps of:
determining, by the radio base station, only one mobile station to be scheduled in each scheduling assignment slot; transmitting a first scheduling grant information to a first mobile station scheduled in a current scheduling assignment slot, and transmitting a second scheduling grant information to a second mobile station to be scheduled in a next scheduling assignment slot by the radio base station at a time of switching between mobile stations to be scheduled, the first scheduling grant information instructing to stop transmission of the MAC-e PDU in a next transmission time interval, the first scheduling grant information corresponding to a minimum size of the MAC-e PDU which can contain only one MAC-d PDU; and transmitting, by the second mobile station, the MAC-e PDU with the size corresponding to the second scheduling grant information in the next scheduling assignment slot, wherein the MAC-d PDU is 336 bits and the minimum size of the MAC-e PDU is 354 bits.
