Abstract
The present invention relates to a mobile communication system, and more particularly, to a method of adjusting a signal power in a variable data rate mode. Accordingly, the present invention includes steps of allocating a reference pilot signal level to each of a plurality of data rates supported by the system and adjusting the reference pilot signal level for a changed data rate based on an external control information and adjusting a power control threshold for secondly adjusting the reference pilot signal level corresponding to the reference pilot signal level.
Claims35
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- allocating a reference pilot signal level to each of a plurality of data rates supported by the system;
- adjusting the reference pilot signal level for a changed data rate based on an external control information;
- and
- adjusting a power control threshold for secondly adjusting the reference pilot signal level corresponding to the reference pilot signal level.
The method of claim 5, wherein the power control threshold is adjusted in accordance with the reference pilot signal level of a group to which the changed data rate belongs.
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- classifying the data rates supported by the communication system into a predetermined number of groups;
- allocating a reference pilot signal level to each of the data rates;
- reporting a change of the data rate group to a different group if a changed data rate based on an external control information is the highest or lowest data rate among the data rates which a group includes;
- adjusting a power control threshold for adjusting the reference pilot signal level after transmitting a change-approval message in response to the reporting;
- and
- adjusting the power of the pilot signal corresponding to the changed group. after receiving the approval message.
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- determining a data rate based on an external control information;
- continuously transmitting information of the determined data rate for a predetermined time;
- adjusting a power control threshold for adjusting a reference pilot signal level by monitoring the transmitted information for the predetermined time;
- and
- adjusting the reference pilot signal level for transferring data in accordance with the changed data rate after the predetermined time.
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- determining an effective data rate changed from a present frame (i.e., i-th frame) based on an external control information;
- comparing the determined data rate with each data rates of previous N frames;
- and
- adjusting a reference pilot signal level for transferring data according to a result of comparison;
- and
- adjusting a power control threshold for secondly adjusting the reference pilot signal in accordance with the reference pilot signal level corresponding to the changed data rate.
A method of adjusting a signal power in a variable data rate mode in a mobile communication system, comprising:
- allocating a reference pilot signal level for transferring data to each of a plurality of data rates supported by the system;
- changing a transmission data rate according to the data rate control information;
- and
- changing a level of a pilot signal according to the changed transmission data rate.
