摘要： Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, wherein the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, wherein the random access response message comprises downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.

摘要： Disclosed in the present application are a data transmission method and device, solving the problem of using a dynamic uplink-downlink resource division manner for data transmission in a new wireless communication system. The method comprises: a terminal determining the start position of a time unit of the terminal, and determining the division of an uplink region and a downlink region in the time unit; the terminal detecting a downlink control channel in the downlink region of the time unit; and according to the detection result, the terminal performing an uplink transmission in the uplink region corresponding to the downlink region. As a terminal uses a time unit specific to the terminal for transmission, time units of different terminals may have different start positions, and the number and lengths of the uplink regions and/or downlink regions included in the time units of different terminals may also be different. Thus, the invention can support flexible and variable resource division.

摘要： The application discloses an ACK/NACK feedback method and an associated apparatus serving to resolve the problem arising from data in different transmission time intervals having different transmission and processing latencies, leading to different earliest time points to transmit an ACK/NACK feedback message, and subsequently resulting in being unable to ensure normal ACK/NACK feedback in downlink transmission. The method comprises: a terminal receives a first physical downlink control channel having downlink control information containing a first indication field, the first indication field indicating a time-domain position of ACK/NACK feedback message; and the terminal determines, according to the first indication field, the first physical downlink control channel or the time-domain position of the ACK/NACK feedback message of a first physical downlink shared channel corresponding to the first physical downlink control channel, and transmits, at the time-domain position of the ACK/NACK feedback message, the ACK/NACK feedback message.

摘要： Disclosed in the present invention are a method and device for transmitting and detecting a synchronous signal, which is used to solve the problem that there is currently no clear solution as to how should a terminal detect a synchronous signal when multiple types of base-band numerology are defined in a new wireless communication system. The method comprises: a terminal determining a base-band numerology used to detect a synchronous signal; the terminal detecting the synchronous signal according to the determined base-band numerology. The terminal first determines a base-band numerology used to detect a synchronous signal before detecting said synchronous signal, and then detects the synchronous signal according to the determined base-band numerology, so as to identify the base-band numerology used in the synchronous signal transmission in future communication systems which support multiple types of base-band numerology, thereby correctly detecting the synchronous signal.
