Abstract

According to one embodiment of the present invention, provided is a wireless equipment for transmitting an uplink signal through a reduced transmission resource block (RB) in a wireless communication system. The wireless equipment can comprise: a processor; and a radio frequency (RF) unit for transmitting an uplink signal under control of the processor. When the RF unit is set to a predetermined channel bandwidth and a predetermined frequency range and must satisfy a predetermined maximum allowed value of spurious radiation to protect another frequency range, the uplink signal can be transmitted according to a predetermined maximum number of RBs instead of a total number of RBs for the predetermined channel bandwidth.

Description

technical field [0001] The present invention relates to transmission resource block constraints and power reduction. Background technique [0002] 3GPP (Third Generation Partnership Project) LTE (Long Term Evolution), an advanced version of UMTS (Universal Mobile Telecommunications System), was introduced in 3GPP Release 8. [0003] 3GPP LTE employs OFDMA (Orthogonal Frequency Division Multiple Access) on the downlink and SC-FDMA (Single-Carrier Frequency Division Multiple Access) on the uplink. In order to understand OFDMA, the knowledge of OFDM is first given. OFDM can be used by attenuating inter-chip boundary interference with low complexity. OFDM converts serially input data into N parallel data items and transmits the converted data items on N orthogonal carrier waves. Carriers maintain frequency orthogonality. Meanwhile, OFDMA refers to a multiple access scheme that independently provides each user with some subcarriers available in a system employing OFDM as its ...
