    Abstract: The present invention provides a information processing method at a terminal or a base station. The method at the terminal includes: receiving scheduling information of a physical downlink shared channel (PDSCH) carrying system information, the scheduling information of the PDSCH carried in a master information block (MIB) or downlink control information on an enhanced physical downlink control channel (EPDCCH) sent from the base station, wherein the scheduling information of the PDSCH is used for determining at least one kind of transmission information of the PDSCH; determining the transmission information of the PDSCH according to the scheduling information of the PDSCH. In this way, an extra overhead of a control instruction when a PDCCH is used to schedule a SIB in the prior art is reduced.

    Abstract: The present invention relates to an uplink information sending method which includes: receiving downlink control information DCI and a time division duplexing TDD uplink-downlink configuration that are sent by a base station; determining, according to the TDD uplink-downlink configuration, that an uplink index UL Index field or a downlink assignment index DAI field exists in the DCI; and sending uplink information corresponding to the DCI to the base station according to the UL Index field that exists and in an uplink subframe corresponding to the UL Index field that exists; or sending HARQ-ACK information corresponding to the DAI field that exists to the base station according to the DAI field that exists. The present invention can ensure that the UL Index field or the DAI field functions normally, and further can reduce an increase in downlink control signaling overheads or uplink control signaling overheads and improve a system capacity.

    Abstract translation: 本发明涉及一种上行链路信息发送方法，包括：接收由基站发送的下行链路控制信息DCI和时分双工TDD上行链路 - 下行链路配置; 根据TDD上行链路 - 下行链路配置，确定DCI中存在上行链路索引UL索引字段或下行链路分配索引DAI字段; 根据存在的UL索引字段和对应于存在的UL索引字段的上行链路子帧，向基站发送对应于DCI的上行链路信息; 或者根据存在的DAI字段将与存在的DAI字段对应的HARQ-ACK信息发送到基站。 本发明可以确保UL索引字段或DAI字段正常工作，并且还可以减少下行链路控制信令开销或上行链路控制信令开销的增加并提高系统容量。

    Abstract: An environmental imaging method includes: A first device sends first indication information to a second device, where the first indication information indicates a first spatial location at which the second device is to send a measurement signal, and the first spatial location is evenly distributed in an azimuth direction and/or at an azimuth angle; the first device receives an echo signal, where the echo signal is a signal formed by reflecting, by a target, the measurement signal sent by the second device after the measurement signal arrives at the target; and the first device performs imaging on the target based on the echo signal. The method may be implemented in a system or an apparatus.
