摘要： A method of notifying resource allocation for Demodulation Reference Signal (DMRS) is provided. A base station notifies to a user equipment a power offset value between an average EPRE value for data symbols and an average EPRE value for the DMRS at each layer in a semi-static or static manner. Also, the base station dynamically notifies to the user equipment a current channel rank or a current DMRS distribution pattern for the user equipment. The user equipment determines an allocated DMRS antenna port based on a correspondence between the received channel rank and an allocation of DMRS antenna port, thereby obtaining resource allocation information for the DMRS. The signaling overhead for power allocation in the system can be reduced, the efficiency of power amplifier can be improved and the flexibility of system scheduling can be increased. A method of notifying antenna port resource allocation for DMRS is also provided.

摘要： The present invention discloses a method for transmitting physical uplink control information, a base station (BS) and a user equipment (UE), combining channel information feedback based on non-periodic PUSCH and channel information feedback based on periodic PUCCH. The BS activates reception of one or more downlink Secondary Component Carriers (SCCs) by the UE, and notifies the UE of resources for non-periodic transmission of uplink control information. The UE jointly codes Channel State Indicators (CSIs) for downlink Component Carriers (CCs) including a downlink SCC and/or a downlink Primary Component Carrier (PCC) and transmits them to the BS by using the resources. The BS performs a downlink scheduling based on the CSIs. The UE feeds CSIs for the downlink CCs back to the BS periodically, such that the BS can track variation in the CSIs for the downlink CCs. With the present invention, it is possible to address challenges in designs for transmitting physical uplink control information in the LTE R-10 system.

摘要： A novel scheme for Pre-coding Matrix Index (PMI) transmission over Physical Uplink Shared Channel (PUSCH) is provided for Channel State Information (CSI) feedback in dual codebook pre-coding architecture. According to the present invention, the PMI is decomposed into a frequency-selective portion and a non-frequency-selective portion, which are then jointly coded. The frequency-selective portion of the PMI can be one of a beam selection portion and a phase combination portion of the PMI while the non-frequency-selective portion of the PMI can be the other one of the beam selection portion and the phase combination portion of the PMI. The present invention has advantages such as simple implementation and low signaling overhead and is applicable in LTE-Advanced/4G cellular communication systems and future 5G cellular communication system.

摘要： The present invention discloses a channel reconstruction method for a downlink multi-antenna-multi-base-station with inconsistent antenna configuration. Firstly, a serving base station configures a user equipment. If antenna configuration of the multi-antenna-multi-base-station system is inconsistent, virtual antennas are introduced to a base station with fewer antennas in the system. A user equipment selects and feeds back indices of the virtual antennas and reconstructs channels of the multi-antenna-multi-base-station system to generate a consistent antenna configuration. Finally, the multi-antenna-multi-base-station system transmits a signal to the user equipment by adopting a transmission pre-processing scheme of the consistent antenna configuration. The present invention provides also a serving base station, a cooperative base station and a user equipment for realizing the channel reconstruction method. The present invention has advantages of large application range, simple implementation and better performance.
