    Abstract: A first device senses scheduling assignment (SA) and received power of a second device, and a total received energy of each subband. The first device determines a reference value of received power of the second device and a reference value of total received energy, based on a sensing result of the second device. The first device selects a resource, based on the reference value of received power and reference value of total received energy, the first device transmits data. By adopting the method of the present disclosure, decoding performance of SA is improved, and accuracy for measuring received power of the SA is also enhanced. Subsequently, on the basis of SA and received power, performances for selecting/re-selecting channel resources are improved.

    Abstract: An embodiment of the present invention provides a method for processing Physical Downlink Shared Channel (PDSCH) data, to be applied in a system, which supports to adjust uplink and downlink (UL-DL) configurations for Time Division Multiplexing (TDD) dynamically. The method includes: receiving, by a User Equipment (UE), a System Information Block 1 (SIB1); obtaining, by the UE, from the SIB1 a TDD UL-DL configuration employed by the UE in current system, in which the UE doesn't support dynamic service adaption; determining, by the UE, subframe type of subframe 6, wherein the subframe type of subframe 6 is a special subframe or a normal downlink subframe; and determining, by the UE, number of Orthogonal Frequency Division Multiplexing (OFDM) symbols used for PDSCH transmission within subframe 6, based on the subframe type of subframe 6, and processing the PDSCH data of subframe 6. By adopting the technical solution provided by embodiments of the present invention, in a system which supports to dynamically adjust the TDD UL-DL configurations, a UE may be enabled to explicitly learn number of OFDM symbols used for the PDSCH transmission within subframe 6. Meanwhile, the UE and an evolved Node B (eNB) may be enabled not to confuse the number of OFDM symbols used for the PDSCH transmission.

    Abstract: A base station includes a reference signal allocator that allocates a first layer of dedicated reference signals and a second layer of reference signals to the same resource elements in a first resource block. The reference signals are allocated to two adjacent resource elements corresponding to a first OFDM symbol and a second OFDM symbol on a first, second, and third subcarriers of the first resource block. The base station also includes a reference signal multiplexer that multiplexes the first layer with the second layer. A first cover code W1 is applied to the first layer. A second cover code W2, different from the first cover code, is applied to the second layer in a first and third subcarriers, and a variation of the second cover code W2′ is applied to the second layer in a second subcarrier.
