Abstract: A method for obtaining feedback delay includes: obtaining a target time elapsed in a process from when a remote radio end receives uplink data sent from a user end to when the remote radio end sends out feedback information responsive to the uplink data to the user end, wherein the feedback information responsive to the uplink data is fed back by a processing node to the remote radio end; calculating a feedback delay by adding the target time and an air interface transmission propagation delay, wherein the air interface transmission propagation delay is a transmission time of the uplink data from the user end to the remote radio end; and configuring, by the processing node, an uplink hybrid automatic repeat request (HARQ) ACK/NACK feedback interval to be the feedback delay.

Abstract: A data transmission resource determining method includes determining an initial time interval and an interval difference, and determining, based on a initial time interval and a interval difference, a time domain position of a first time-frequency resource in response to the first TB being transmitted for an ith time, where i is a positive integer, and 2≤i≤Rmax+1. The initial time interval is between a time domain position at which a first transport block (TB) is transmitted for the first time and the second time. The interval difference is a difference between a first and a second time interval. The first time interval is between a corresponding time domain position at which the first TB is transmitted for a kth h time and (k+1)th time. The second time interval is between a corresponding time domain position at which the first TB is transmitted for the (k+1)th time and (k+2)th time.

Abstract: A random access method includes determining, by a user equipment (UE), a preamble sequence. The method also includes generating, by the UE, a scrambling code. The scrambling code is based on the preamble sequence. The method further includes scrambling, by the UE, data based on the scrambling code to obtain scrambled data. The method additionally includes determining, by the UE based on a predetermined resource mapping relationship, time-frequency resources for sending the scrambled data. The method also includes sending, by the UE on the determined time-frequency resources, the scrambled data to a base station.
