    摘要： A transmission point device, user equipment, and method of reporting phase offsets between signals received from a serving cell and neighbor cells in a communication system are disclosed. The method comprises steps of: quantizing the phase offsets using a predetermined number of bits; utilizing another bit to indicate constellation of the phase offsets; reporting the quantized phase offsets and the constellation to transmission point. The present disclosure may improve the signal combining gain from multiple transmission points with minimum overhead increasing.

    摘要： Method of scrambling signals, transmission point device and user equipment using the method are provided. The method is for scrambling signals assigned on predetermined radio resources of at least one layer of resource blocks with the same time and frequency resources, and comprises the steps of: sending an ID table to a user equipment through higher layer signaling, the ID table being a subset of the whole ID space and containing available IDs for the user equipment; notifying the user equipment an ID in the ID table to be used through physical layer signaling or UE specific higher layer signaling; generating a random seed based on the notified ID; initializing a scrambling sequence by the random seed; and scrambling the signals with the initialized scrambling sequence. The method of the disclosure, by combining physical layer signaling and higher layer signaling, may notify the used group ID and the blind detection space to a UE, the blind detection for the UE is enabled and the signaling overhead is reduced.

    摘要： A method and device for adjusting a timing advance in a communication system composed of a mobile terminal and multiple base stations is provided. The method includes steps: the multiple base stations measures channel latencies and powers of channel responses between the mobile terminal and the multiple base stations separately; the non-serving base station in the multiple base stations reports the channel latency and the power measured to a serving base station; and the serving base station determines the timing advance of the uplink of the mobile terminal according to the channel latency and the power received and the channel latency and the power which are measured by the serving base station itself, and informs the mobile base station of the timing advance. By using the method and the device, the useful power received by the uplink multi-base stations can be optimized, and the interference power can be effectively reduced.

    摘要： A method, mobile terminal, and system for reporting BCI are provided, the method comprises the steps of: obtaining a PMI W1 set and a PMI W2 to be used for a mobile terminal based on a double codebook; computing a BCI W1 set to be used for another mobile terminal based on the PMI W1 set; selecting a BCI W2 from the BCI W1 set based on the PMI W2; and reporting the BCI W1 set and the BCI W2 to a base station, wherein W1 indicates a long-term or wideband component of the PMI and BCI, and W2 indicates a short-term or narrowband component of the PMI and BCI. With the present disclosure, the probability that the optimal BCI W2 is included in the shifted BCI W1 set is increased, and the overhead for feeding-back the BCI is reduced.
