Abstract
The present invention relates to a wireless communication system and, more particularly, to a method of transmitting and receiving frame in a wireless communication system. A method for transmitting a frame of a base station in a wireless communication system comprises the steps of transmitting a first region of the frame to a mobile station by using a first traffic to pilot ratio (hereinafter referred to as “TPR”); and transmitting a second region of the frame to the mobile station by using a second TPR, wherein the second TPR is different from the first TPR.
Claims4
A method for transmitting a frame comprising first, second and third regions in a wireless communication system, the method performed by a base station and comprising:
- receiving information related to a target Frame Error Rate (FER);
- adjusting a Traffic to Pilot Ratio (TPR) of a transmitted signal according to the received information related to the target FER;
- selecting a TPR boost value set among a plurality of TPR boost value sets, wherein the selected TPR boost value set includes TPR boost values for each of the first, second and third regions of the frame;
- transmitting information related to the TPR and an index of the selected TPR boost value set;
- calculating first, second and third TPRs by multiplying the adjusted TPR and the selected TPR boost value set for each of the first, second and third regions;
- and
- transmitting the first, second and third regions using the calculated first, second and third TPRs,
- wherein:
- the second region is positioned alter the first region;
- the TPR boost value for the second region is smaller than the TPR boost value for the first region;
- the third region is positioned after the second region;
- and
- the TPR boost value for the third region is greater than the TPR boost value for the second region.
A method for receiving a frame comprising first, second and third regions by in a wireless communication system, the method performed by a mobile station and comprising:
- transmitting information related to a target Frame Error Rate (FER);
- receiving information related to a Traffic to Pilot Ratio (TPR) and an index of a TPR boost value set from a plurality of TPR boost value sets, wherein the TPR boost value set includes TPR boost values for each of the first, second and third regions of the frame;
- calculating first, second and third TPRs by multiplying an adjusted TPR and the received TPR boost values for each of the first, second and third regions;
- and
- receiving the first, second and third regions using the calculated first, second and third TPRs,
- wherein:
- the second region is positioned after the first region;
- the TPR boost value for the second region is smaller than the TPR boost value for the first region;
- the third region is positioned after the second region;
- and
- the TPR boost value for the third region is greater than the TPR boost value for the second region.
