Abstract: The present invention provides a downlink channel decoding method, a downlink information transmission method, a user equipment, and a base station. The downlink channel decoding method includes: determining, by a user equipment, a resource unit occupied by a DMRS; and decoding a downlink channel based on the DMRS transmitted on the resource unit. The present invention can enable different DMRS patterns to concurrently exist on an NCT carrier. In a downlink transmission process, a DMRS pattern used for downlink transmission is determined according to priorities of different channels and/or signals, which can ensure optimal performance of a high-priority channel and/or signal, and can further improve downlink transmission performance.

Abstract: The present disclosure relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI trigger signaling, so that a base station transmits a CSI-RS only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced.

Abstract translation: 本公开涉及用于报告信道状态信息的方法，用户设备和基站。 信道状态信息测量资源由UE根据非周期性CSI触发信令确定，使得仅当UE需要报告非周期性CSI时，基站才发送CSI-RS。 与现有基站发送周期性CSI-RS相比，减少了CSI-RS的不必要的发送，节省了诸如eNB的基站的能量; 减少CSI-RS传输可能会减少CSI-RS占用的资源，从而提高系统的频谱效率。 此外，减少不必要的CSI-RS传输允许基站的其他小区的干扰减少; 最后，CSI测量资源只有在需要反馈的情况下才被保留，CSI测量资源占用的成本就会降低。

Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.

Abstract: In a handover process, a source base station can send information about a band combination to a target base station (such as a master base station). The band combination includes a band of the target base station and a band of a secondary base station. After receiving the information about the band combination, the target base station can add the secondary base station in the handover process or add the secondary base station immediately after the handover is completed.

Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: Embodiments of the present invention provide a channel-state information process processing method, a network device, and a user equipment, where the channel-state information process processing method includes: after receiving a first channel-state information CSI request sent by a first network device, if CSI corresponding to multiple aperiodic CSI processes has not been reported by a user equipment, dropping CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement resource and an interference measurement resource. A problem existing after a CoMP technology is introduced can be solved that the UE cannot implement processing of multiple CSI processes.
