Abstract:
1. A method for determining data amounts for scheduled and autonomous transmission, the method comprising: receiving, by a user equipment (UE), information related to an allowed power for autonomous transmission on at least one logical channel mapped to an uplink channel, the uplink channel being set up with a base station and dedicated for packet data transmission; determining, by the UE, in accordance with a scheduling grant received from the base station, an allowed power of scheduled transmission on the uplink channel; determining, according to a total power available for the uplink channel, a total data amount allowed to be transmitted; determining a data amount for the autonomous transmission on the logical channel, the determined autonomous transmission data amount being a smaller value between an allowed autonomous transmission data amount corresponding to the allowed autonomous transmission power and an autonomous transmission data amount corresponding to a required autonomous transmission power; subtracting from the total data amount allowed to be transmitted on the logical channel the determined autonomous transmission data amount after determining the autonomous transmission data amount on the logical channel; updating the total data amount allowed to be transmitted on the logical channel with the subtraction result; and determining a data amount for scheduled transmission on the logical channel, the determined scheduled transmission data amount being a smaller value between an allowed scheduled transmission data amount corresponding to the allowed scheduled transmission power and a scheduled transmission data amount corresponding to a required scheduled transmission power, wherein the data amount for scheduled transmission is determined, after the data amount for the autonomous transmission is determined, and wherein the determined scheduled transmission data amount is limited to be no greater than the updated total data amount allowed to be transmitted on the logical channel.
