    摘要: Techniques for efficiently multiplexing a reference signal and data on different sets of subcarriers in the same symbol period are described. In one design, a user equipment (UE) performs a discrete Fourier transform (DFT) on a set of modulation symbols for data to obtain data symbols. The UE also obtains reference symbols generated based on a reference signal sequence corresponding to a cyclic shift of a base sequence. The UE maps the reference symbols to a first set of subcarriers and maps the data symbols to a second set of subcarriers. The UE then generates a transmission symbol based on the mapped reference symbols and the mapped data symbols. The UE may also transmit reference signals and data (i) in multiple symbol periods of a slot or a subframe and/or (ii) from multiple antennas using frequency division multiplexing (FDM) or code division multiplexing (CDM).

    摘要: A method for discontinuous transmission (DTX) signaling in a physical uplink shared channel (PUSCH) of a wireless communication system includes puncturing at least a portion of a physical uplink shared channel (PUSCH) at a location that would collide with acknowledgement (ACK)/negative (ACK/NACK) feedback if ACK/NACK feedback is transmitted. The method also includes transmitting DTX symbols in the punctured portion of the PUSCH by a user equipment (UE). The method further includes detecting DTX symbols on the PUSCH by an evolved Node B (eNodeB), indicating the UE is operating according to a DTX signaling mode.

    摘要: A wireless communication method includes allocating physical uplink control channel (PUCCH) data in first slot to a first orthogonal cover code (OCC). The method also includes allocating PUCCH data in a second slot of the same subframe to a different orthogonal cover code (OCC). Another method includes mapping PUCCH resources to physical resource blocks based on a user equipment (UE) specific signaling parameter (e.g., a resource index) and a number of symbols in a slot of a subframe.

    摘要: Methods and apparatuses are provided that include providing transmit diversity for data channel transmissions. Different precoding vectors can be used over different slots of a given subframes to precode corresponding signals. The precoding vectors, in one example, can be orthogonal. In addition, using the different precoding vectors can be determined based on a user equipment receiving an indicator from a base station receiving the data channel transmissions of whether to use frequency hopping over the slots. Moreover, precoding vectors used to precode data channel transmissions can additionally or alternatively vary across subframes.
