Abstract: The disclosed techniques provide a method and apparatus for transmitting and receiving system information, base station, and terminal. The method of transmitting system information comprises: configuring, by a base station, a radio frame for transmitting system information in a system information window with a system information repetition pattern; and, starting, by the base station, to transmit the system information in an available radio subframe of the radio frame indicated by the system information repetition pattern, wherein if there are not enough available radio subframes for transmitting the SI one or more times in the radio frame indicated by the system information repetition pattern, the system information is repeatedly transmitted one or more times in an available radio subframe in a specified radio frame. With this technical solution, the problem in related techniques that the system information cannot be transmitted using the prior art as the number of radio subframes that system information needs to occupy increases is solved, such that regardless of a size of the system information, a suitable number of radio subframes can be selected and thereby network resources are reasonably used.

Abstract: The present invention provides a data transmission method and apparatus. The method includes: transmitting physical downlink channel data according to a first-type reference signal (RS) or a second-type RS or a third-type RS. The method of the present invention ensures a balance between data transmission performance and RS overheads for different NarrowBand-Internet Of Things (NB-IOT) physical downlink channel data, thereby resolving the problem in the related art of not knowing which RS is to be used to transmit NB-IOT physical channel data.

Abstract: The present invention provides a method and an apparatus for determining a position of a terminal, and a storage medium. The method comprises: sending first DCI or a paging message to a terminal, wherein the first DCI or the paging message is used for triggering the terminal to send a signal and the transmission of the first DCI is started at a paging moment of the terminal; and determining a position of the terminal according to the signal sent by the terminal. The technical solution solves the problem in the related art that a position of a terminal is determined only depending on an uplink signal sent by the terminal device in a connected state, and can easily determine the position of the terminal, thereby avoiding unnecessary power consumption of the terminal and helping saving power of a terminal device.

Abstract: This disclosure provides techniques for reducing waste of user equipment (UE) resources caused in transmission of a Physical Uplink Shared Channel (PUSCH) when a UE conducts searching for downlink control information (DCI) outside of a PUSCH transmission. This disclosure defines a first search space on the basis of an existing second search space that was used to receive DCI information to schedule a PUSCH. The first search space can be used to obtain a DCI having an ACK feedback. This disclosure provides systems and methods for determining the location of the first search space to receive a second DCI having ACK feedback during a PUSCH repetitive transmission and whether the second search space should be used for the second DCI instead. Outside of the PUSCH transmission, the UE receives DCI in the second search space, decreasing the unnecessary searching of DCI and increasing network efficiency.
