Abstract:
1. A method of controlling transmission power associated with an uplink channel in a wireless communication system, the method comprising: receiving, by a user equipment (UE), transmission power control (TPC) information multiplexed with user data via a physical downlink shared channel (PDSCH) of a downlink channel according to allocated persistent resources; determining the transmission power for the PUSCH according to controlling, by the UE, the transmission power by using the TPC information; and transmitting, by the UE, uplink data, via an uplink channel that is a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH), with the controlled transmission power, wherein one subframe of the downlink channel comprises a physical downlink control channel (PDCCH) followed by the PDSCH, the PDCCH comprising at least three orthogonal frequency division multiple access (OFDMA) symbols, wherein the TPC information is not included in the PDCCH, wherein the TPC information is multiplexed with the user data by punctuating resource elements which include a portion of the user data, and wherein P wherein P wherein M wherein P wherein ‘α’ is a 3-bit cell specific parameter, PL is a downlink pathloss estimate calculated in the UE, wherein Δ wherein TF(i) is a PUSCH transport format valid for the i-th subframe, f(i) is a factor determined by δ wherein δ
