    摘要： Disclosed are a resource configuration method and apparatus, and a computer storage medium, being used for enabling, when a remaining minimum system information control resource set and an associated synchronization information block are in a time division multiplexing mode, the configuration of the remaining minimum system information control resource set to be more flexible, being applicable to more application scenarios. The resource configuration method comprises: determining that a remaining minimum system information control resource set (RMSI CORESET) and an associated synchronization information block (SS Block) occupy different symbols for transmission in a time division multiplexing mode; and determining the configuration parameters of the RMSI CORESET and the associated SS Block, the remaining minimum system information control resource sets associated with the SS Blocks in each SS Block burst set having identical configuration parameters.

    摘要： The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.

    摘要： The present application relates to the field of wireless communications, and in particular, to a method and device for random access, for use in resolving the problem in the prior art of conflict between a time domain resource used by a terminal for random access and a time domain resource occupied for transmission of a SS Block and/or RMSI. In embodiments of the present application, a terminal determines a PRACH time domain resource configured by a base station for the terminal; when determining that at least one time slot comprises a first type of OFDM symbols used for transmission of a SS Block and/or RMSI, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the at least one time slot. In the embodiments of the present application, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the time slot, so that conflict between the time domain resource used for random access and the time domain resource occupied for transmission of the SS Block and/or RMSI is avoided, and the system performance is further improved.

    摘要： An uplink scheduling-free transmission method and an uplink scheduling-free transmission device are provided. The uplink scheduling-free transmission method includes: dividing, by a base station, MA resources into groups of MA resources, and configuring, by the base station, the groups of MA resources to obtain at least two groups of MA resource pools, wherein at least parts of respective MA resources in the at least two groups of MA resource pools are different from each other; and notifying, by the base station, a UE of the at least two groups of MA resource pools, to enable the UE to select an MA resource pool from the at least two groups of MA resource pools, wherein the selected MA resource pool is to be used by the UE.

    摘要： The present disclosure discloses an uplink detection method and device in a NOMA system. The method includes: performing pilot activation detection on each terminal in a first terminal set corresponding to a NOMA transmission unit block repeatedly until a detection end condition is met, wherein the first terminal set includes terminals that may transmit uplink data on the NOMA transmission unit block; performing channel estimation on each terminal in a second terminal set that determined through the pilot activation detection within each repetition period, wherein the second terminal set includes terminals that have actually transmitted uplink data on the NOMA transmission unit block; and detecting and decoding a data channel of each terminal in the second terminal set within each repetition period. In the technical solution provided by the embodiment of the present disclosure, a probability of error of the pilot activation detection and data detection at the base station side is reduced effectively, and the accuracy of the pilot activation detection and the data detection is improved.
