Abstract
A method implemented in a user equipment (UE) used in an orthogonal frequency division multiple access (OFDMA) wireless communications system supporting coordinated multi-point (CoMP) joint transmission (JT) is disclosed. The method includes measuring reference signal received power (RSRP), transmitting, to a network, first feedback on the RSRP, receiving, from the network, a CoMP measurement set, conducting pre-scheduling CoMP UE fallback according to the CoMP measurement set, computing channel quality and direction information according to a UE category, and transmitting, to the network, second feedback on the channel quality and direction information. Other methods, apparatuses, and systems also are disclosed.
