    摘要: Systems and methods are disclosed for using multiple configuration groups having corresponding configuration identity (CID) parameters to configure a transmission channel and a reception channel for a user equipment device in a cellular communication network. In one embodiment, a user equipment device in a cellular communication network obtains CID values for CID parameters for a number of configuration groups. Each of the configuration groups includes one or more transmission channel or reception channel parameters. For each of the configuration groups, the user equipment device configures the parameters in the configuration group based on the CID value obtained for the CID parameter for the configuration group. In this manner, the transmission channel and the reception channel for the user equipment device are configured based on multiple CID values rather than a single physical layer cell identifier for a cell in which the user equipment device is located.

    摘要: Techniques are disclosed for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions. In one example method, a signal includes B bits for identifying a reference signal is received, wherein each of several available reference signals is defined by a cyclic shift and an orthogonal cover code. The B bits are used to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

    摘要: Determining transmitter antenna weights at a base station having more available transmit antennas than the available number of reference signals can be performed by transmitting reference signals and receiving channel feedback data derived by a mobile terminal from the reference signals. The reference signals are each assigned to one of two or more antenna groupings, wherein at least a first one of the antenna groupings includes two or more transmit antennas, and transmitted using at least one transmit antenna from the corresponding antenna grouping. A first beam-forming vector for the first one of the antenna grouping is determined, and mapping the one or more data streams to the transmit antennas according to a final precoding matrix that depends on the channel feedback data and the first beam-forming vector is performed, to obtain a weighted transmit signal for each of the antennas.

    摘要: A method of estimating frequency offset of a received signal in a terminal apparatus comprises a) determining a phase change between a first and a second reference symbol of the received signal, wherein the time distance t between the first and the second reference symbols is associated with an observation frequency f such that f=1/t. The method further comprises: b) determining a preliminary frequency offset Δf based on the determined phase change, wherein Δf forms a frequency offset hypothesis Δfh; and c) decoding at least a part of the received signal, with application of the frequency offset hypothesis Δfh, to a decoded signal. The method further comprises: d) determining whether the decoded signal is a successful decoding. If the decoded signal is a successful decoding, the frequency offset hypothesis Δfh is determined to be the estimated frequency offset, but if the decoded signal is not a successful decoding, the frequency offset hypothesis Δfh is adjusted by an integer n times the observation frequency f such that Δfh=Δf+n·f, where nε[+/−1, 2, 3, . . . ]. Steps c) and d) are then repeated.
