Abstract

A method for transmitting, by a terminal, a high-speed uplink signal to a base station in a wireless communication system is disclosed. Specifically, the method for transmitting a high-speed uplink signal comprises the steps of: setting a plurality of resource blocks as a resource pool for transmitting a high-speed uplink signal through an upper layer signal; selecting at least one resource block from the resource pool; and transmitting the high-speed uplink signal including a transmission block on the selected resource block to a base station, wherein the size of the transmission block is determined on the basis of the number of the selected resource blocks.

First claim

What is claimed is:

1 . A method for transmitting a high-speed uplink signal to an evolved node B (eNB) by a user equipment (UE) in a wireless communication system, the method comprising:
setting a plurality of resource blocks (RBs) as a resource pool for transmitting the high-speed uplink signal through a higher layer signal; selecting one or more RBs from the resource pool; and transmitting, to the eNB, the high-speed uplink signal including a transport block (TB) on the selected RBs, wherein a size of the TB is determined based on the number of the selected RBs.

2 . The method of claim 1 , further comprising setting the number of RBs that can be selected from the resource pool through the higher layer signal.

3 . The method of claim 1 , wherein maximum transmission power of the high-speed uplink signal is determined based on the number of the selected RBs.

4 . The method of claim 1 , further comprising receiving a response signal in response to the high-speed uplink signal from the eNB, wherein resources for receiving the response signal are determined based on the number of the selected RBs.

5 . The method of claim 1 , wherein the one or more RBs are selected based on channel quality between the UE and the eNB.

6 . The method of claim 1 , wherein a ratio of the TB size to a maximum TB size corresponding to the resource pool corresponds to a ratio of the number of the selected RBs to the number of RBs included in the resource pool.

7 . A user equipment (UE) in a wireless communication system, the UE comprising:
a wireless communication module for transmitting and receiving signals through a network; and a processor for processing the signals, wherein the processor is configured to set a plurality of resource blocks (RBs) as a resource pool for transmitting a high-speed uplink signal through a higher layer signal, select one or more RBs from the resource pool, and control the wireless communication module to transmit the high-speed uplink signal including a transport block (TB) on the selected RBs to an evolved node B (eNB), and wherein a size of the TB is determined based on the number of the selected RBs.

8 . The UE of claim 7 , wherein the processor is configured to set the number of RBs that can be selected from the resource pool through the higher layer signal.

9 . The UE of claim 7 , wherein the processor is configured to determine maximum transmission power of the high-speed uplink signal based on the number of the selected RBs.

10 . The UE of claim 7 , wherein the processor is configured to control the wireless communication module to receive a response signal in response to the high-speed uplink signal from the eNB and determine resources for receiving the response signal based on the number of the selected RBs.

11 . The UE of claim 7 , wherein the processor is configured to select the one or more RBs based on channel quality between the UE and the eNB.

12 . The UE of claim 7 , wherein a ratio of the TB size to a maximum TB size corresponding to the resource pool corresponds to a ratio of the number of the selected RBs to the number of RBs included in the resource pool.
