    摘要: Coordinated multi-point (CoMP) transmissions in a cellular network is performed using multi-broadcast single frequency network (MBSFN) subframes. During CoMP transmission, demodulation reference signals (DRS) are placed in the one portion the MDSFN subframe, while cell-specific reference signals (CRS) are placed in a separate portion of the MDSFN subframe. Therefore, no CRS-DRS collision will occur during CoMP transmission.

    摘要: A method of mapping data in a wireless communication system is disclosed. The method includes forming a first frame (504) having plural positions at a first transmitter (eNB 1, 200). The first frame has a first plurality of reference signals (500). A second frame (508) has plural positions corresponding to the plural positions of the first frame and is formed at a second transmitter (eNB 2, 450) that is remote from the first transmitter. The second frame has a second plurality of reference signals (506). A plurality of data signals (S1, S2) is inserted into the first frame at positions that are not occupied by either the first or second plurality of reference signals. The plurality of data signals (S1, S2) is inserted into the second frame at positions that are not occupied by either the first or second plurality of reference signals. The first and second frames are transmitted to a remote receiver (UE 1, 106).

    摘要: For transmission of a block of control information within a wireless network, the control information is interleaved to form an ordered set of control bits, wherein more important information bits of the control information are placed into a first portion of the ordered set of control bits, with less important information bits of the control information placed into a second portion of the ordered set of controls bits. The ordered set of control bits is encoded to form an encoded block of data. The encoded block of data is transmitted to a serving base station, wherein bits from the first portion of the ordered set of control bits will statistically have a lower bit error rate (BER) than bits from the second portion of the ordered set of control bits during transmission.
