Embodiment Construction

[0045] As mentioned in the background technology, the carrier / BWP bandwidth range is relatively large. When the bandwidth is greater than 20MHz or less than 20MHz, the NR system lacks support for flexible uplink channel resource indication and resource allocation without restricting carrier / BWP bandwidth allocation. s solution.

[0046] In the prior art, the LAA technology utilizes a Listen-Before-Talk (LBT for short) mechanism to realize coexistence of different communication systems (for example, an LTE system and a Wi-Fi system) in an unlicensed spectrum. The basic principle of the LBT mechanism is: before the node transmits data in the unlicensed spectrum, it first determines whether the current channel is available based on the result of energy detection through the Clear Channel Assessment (CCA) mechanism. Some regional regulations stipulate an energy detection threshold (Energy detection threshold). If the received energy of a node is higher than the specified energy de...

Abstract

A method and device for allocating uplink channel resources, a storage medium, and a base station, the allocating method includes: determining unlicensed spectrum resources available for uplink transmission; A resource distribution scheme; performing staggered resource allocation on the unlicensed spectrum resources according to the staggered resource distribution scheme. The technical solutions provided by the embodiments of the present invention can support flexible uplink channel resource indication and resource allocation without limiting bandwidth allocation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for allocating uplink channel resources, a storage medium, and a base station. Background technique [0002] The 3rd Generation Partnership Project (3GPP) standards organization will study how to deploy the fifth-generation mobile communications (The Fifth-Generation mobilecommunications, 5G) New Radio (NR) on unlicensed spectrum ) system, so as to achieve the purpose of using the unlicensed spectrum fairly and effectively and improving the data transmission rate of the NR system. The NR system uses an unlicensed spectrum technology, which is also called New RAT Unlicense (NR-U for short) technology. There are three main ways of NR-U technology. The first is that the NR cell of the unlicensed spectrum acts as the main cell; the second is that the user equipment (User Equipment, referred to as UE) accesses the unlicensed spectrum NR cel...
