Outer Loop Power Control for E-DCH
First Claim
1. A method for power control in an enhanced uplink (UL) telecommunication system comprising at least one first radio network controller (RNC) and at least one first and one second base station enabling wireless communication with at least one first user terminal, the method comprising:
- the first and the second base stations receiving at least a first transport block (TB), the first TB being transmitted by the user terminal over an established communication channel;
the first and the second base station controlling whether the received first TB includes at least one error;
if at least one error in the first TB is found by the first and/or the second base station, the base station that found the error further controls the number of decoding attempts for the first TB, the number of decoding attempts being stored in a decoding attempt counter;
if the number of decoding attempts for the first TB is equal to a decoding attempt threshold, the base station that found the error further determines if the first TB is a discontinuous transmission frame (DTX) or a TB including errors; and
if the base station determines that the first TB is a DTX, the base station that found the error further resets the decoding attempt counter and prepares the station for a new, second TB.

Abstract
The present invention relates to a method and an enhanced uplink (UL) telecommunication system for power control. The system comprises at least one first radio network controller (RNC) and at least one first and one second base station enabling wireless communication with at least one first user terminal. The first and the second base stations receive at least a first transport block (TB), the first TB being transmitted by the user terminal over an established communication channel. If the received first TB includes at least one error, the base station that found the error controls the number of decoding attempts for the first TB. If the first TB is a discontinuous transmission frame (DTX), the base station resets a decoding attempt counter and prepares the first and second base stations for a new, second TB.

11. A base station adapted for power control in an enhanced uplink (UL) telecommunication system further comprising:
at least one first radio network controller (RNC), at least one first and one second base station in the system enabling wireless communication with at least one first user terminal, wherein the first and the second base stations being adapted to receive at least a first transport block (TB), the first TB being transmitted by the user terminal over an established communication channel, the first (11) and the second (10) base station further being adapted to control whether the received first TB includes at least one error, if at least one error in the first TB is found by the first (11) and/or the second (10) base station, the base station that found the error further being adapted to control the number of decoding attempts for the first TB, the number of decoding attempts being stored in a decoding attempt counter, if the number of decoding attempts for the first TB is equal to a decoding attempt threshold, the base station/-s (10,11) that found the error is further adapted to determine if the first TB is a discontinuous transmission frame (DTX) or a TB including errors and if the first TB is a DTX, the base station that found the error is further adapted to reset the decoding attempt counter and prepares the station for a new, second TB. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An enhanced uplink (UL) telecommunication system adapted for power control, the system comprising:
at least one first radio network controller (RNC) and at least one first and one second base station enabling wireless communication with at least one first user terminal, wherein the first and the second base stations being adapted to receive at least a first transport block (TB), the first TB being transmitted by the user terminal over an established communication channel, the first and the second base station further being adapted to control whether the received first TB includes at least one error, if at least one error in the first. TB is found by the first and/or the second base station, the base station that found the error further being adapted to control the number of decoding attempts for the first TB, the number of decoding attempts being stored in a decoding attempt counter, if the number of decoding attempts for the first TB is equal to a decoding attempt threshold, the base station that found the error is further adapted to determine if the first TB is a discontinuous transmission frame (DTX) or a TB including errors, and if the first TB is a DTX, the base station/-s that found the error is further adapted to reset the decoding attempt counter and prepares the station/-s for a new, second TB. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
