Abstract: A Physical Uplink Shared Channel (PUSCH) transmission method includes the following. It is determined that a first PUSCH overlaps with a second PUSCH in time domain. The first PUSCH is configured by semi-persistent scheduling and the second PUSCH is configured by dynamic scheduling. A relationship between a first priority of the PUSCH configured by the semi-persistent scheduling and a second priority of the PUSCH configured by the dynamic scheduling is determined. The first PUSCH is sent in an overlapped time domain in response to the first priority is greater than the second priority, or the second PUSCH is sent in an overlapped time domain in response to the second priority is higher than the first priority.

Abstract: Disclosed is an HARQ feedback method, belonging to the technical field of wireless communications. The method is implemented by a base station. The method comprises: sending power-saving signals to at least two terminals, wherein the power-saving signals are used for indicating that the at least two terminals execute corresponding actions related to power saving; and receiving HARQ feedback respectively sent, with regard to the power-saving signals, by the at least two terminals, wherein HARQ feedback resources used when the at least two terminals respectively send the HARQ feedback with regard to the power-saving signals do not overlap. According to the present disclosure, the base station sends the power-saving signals to the at least two terminals and receives the HARQ feedback returned, with regard to the power-saving signals, by the at least two terminals by means of using different HARQ feedback resources, thereby reducing collisions when the at least two terminals use the same HARQ feedback resource and improving the feedback efficiency of the terminals with regard to the power-saving signals.

Abstract: A random access method and device may be used in a wireless communications network. The random access method includes selecting a preamble of a message A; determining a logical resource unit for transmitting the message A based on the preamble of the message A, in which the preamble has a predetermined mapping relationship with the logical resource unit, and the logical resource unit includes at least one physical resource unit part, the physical resource unit part is a partial physical resource obtained by dividing a physical uplink shared channel (PUSCH) physical resource; and transmitting the message A through the physical resource unit part included in the logical resource unit.

Abstract: Methods, apparatuses and systems are provided for transmitting data. A method includes: sending a target random access preamble to a base station; receiving a target random access response that is sent by the base station based on the target random access preamble and carries repetition-number-indicating information; and transmitting, in accordance with a target transmission repetition number, the target uplink data to the base station during the random access procedure. The target transmission repetition number indicates a number of times the user equipment is configured to repeatedly transmit the target uplink data to the base station during the random access procedure. The target transmission repetition number is determined based on the repetition-number-indicating information and a target transmission block size. The target transmission block size is for the user equipment to transmit the target uplink data to the base station during the random access procedure.

Abstract: A hybrid automatic repeat request (HARQ) feedback method is applied to a terminal, wherein a base station allocates to the terminal multiple available scheduling resources configured to provide Early Data Transmission (EDT) service. The method includes: selecting an available scheduling resource from the multiple available scheduling resources; sending EDT data to the base station on the selected available scheduling resource; determining a HARQ feedback time point for the EDT data according to a preset rule; and when HARQ information sent by the base station is received at the HARQ feedback time point, determining a transmission result of the EDT data based on the HARQ information.
