Method and apparatus for performing non-scheduled transmission in a mobile communication system for supporting an enhanced uplink data channel
First Claim
1. A method for performing non-scheduled transmission in a user equipment (UE) of a mobile communication system for supporting an enhanced uplink dedicated channel (E-DCH), comprising the steps of:
- receiving non-scheduled transmission information indicating k transmission time intervals (TTIs) for transmitting non-scheduled data via the E-DCH, wherein non-scheduled transmissions can be performed during the k TTIs within a period having N TTIs; and
transmitting data on at least one TTI of the k TTIs within the period;
wherein the parameter k is an integer greater than 0 and less than or equal to a positive integer N.

Abstract
A mobile communication system using an enhanced uplink dedicated transport channel transmits data at a relatively low effective data rate through non-scheduled transmission. Data transmission time intervals for user equipments (UEs) have different values in the non-scheduled transmission and therefore uplink interference is reduced. An non-scheduled transmission period N and the number of non-scheduled transmissions k are determined such that each UE performs the non-scheduled transmission. A Node B and each UE are notified of possible non-scheduled transmission time intervals based on the determined non-scheduled transmission period N and the determined number of non-scheduled transmissions k through signaling. The UE transmits the uplink data without the Node B'"'"'s scheduling at the possible non-scheduled transmission time intervals.
