    摘要: A method for providing transmit diversity in wireless network communications is presented. An indication of a slot structure is received. The slot structure identifies at least a first location of a reference signal within a slot. A first reference signal is transmitted within a first slot using a first antenna. A location of the first reference signal within the first slot is determined by the slot structure. A second reference signal is transmitted within the first slot using a second antenna. A location of the second reference signal within the first slot is determined by the slot structure. In some cases, the slot structure identifies a second location of a reference signal within the slot structure. The second location being offset from the first location, and a third reference signal is transmitted within the first slot at the second location on the first antenna.

    摘要: A method is provided for communication in a wireless telecommunication system. The method comprises transmitting, by a UE, a DMRS, wherein REs carrying the DMRS are separated into a plurality of portions, each of the portions occupying a different OFDM symbol in a single slot of a radio subframe. In one aspect, a new PUSCH DMRS format may provide accurate channel estimates, increased RS density in the time domain at the expense of relaxed PAPR, and/or a symmetric pattern to ease the channel estimation algorithm. The PUSCH DMRS format may provide sufficient RS density in the time domain to enable accurate channel estimation for high Doppler scenarios.
