摘要 |
Methods and apparatuses for transmitting and receiving signaling, by a User Equipment (UE) with reduced processing capabilities, to conserve power are provided. A method for transmitting from a network a Physical Downlink Shared CHannel (PDSCH) to a first User Equipment (UE) from a first class of UEs or to a second UE from a second class of UEs, includes transmitting a PDSCH to the first UE using a first bandwidth unit; and transmitting a PDSCH to the second UE using a second bandwidth unit, wherein the second bandwidth unit is smaller than the first bandwidth unit. |

1. A method for transmitting channel state information by a first user equipment (UE) in a wireless communication system, the method comprising the steps of:
communicating with a base station; and transmitting, to the base station, a first channel quality indicator (CQI) based on a first modulation scheme, wherein the first UE is a machine type communication (MTC) UE, and the first modulation scheme is selected from a first set of modulation schemes, the first set of modulation schemes is different from a second set of modulation schemes used by a second UE, which is a non-MTC UE, the second UE transmitting to the base station a second CQI based on a second modulation scheme selected from the second set of modulation schemes, wherein the first set of modulation schemes includes a quadrature phase shift keying (QPSK) scheme, and the second set of modulation schemes includes a 16 quadrature amplitude modulation (QAM) scheme, a 64 QAM scheme, and the QPSK scheme, and wherein the first CQI is determined based on a rank 1. |
