Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] NB-IoT defines three different coverage levels. User equipment with a high coverage level improves its coverage by repeated repetitions, which is 20dB larger than the traditional coverage. Under the same frequency band, the coverage area is expanded by 100 times. In the coverage enhancement scenario, various channels, such as NPDCCH (Narrowband physical downlink control channel, narrowband physical downlink control channel), NPDSCH (Narrowband physical downlink shared channel, narrowband physical downlink shared channel) and NPUSCH (Narrowband physical uplink shared ...

Abstract

The present application relates to a user equipment uplink scheduling method and device. The method includes: according to the uplink available time-frequency resources, respectively assigning required time-frequency resources to each user equipment waiting for uplink scheduling, and determining each time-frequency position where each user equipment occupies the time-frequency resource; respectively according to each time-frequency position , generating time-domain indication information corresponding to each user equipment; performing data reception and baseband processing on each user equipment according to each time-frequency position and each corresponding time-domain indication information. By allocating required time-frequency resources for each user equipment waiting for uplink scheduling respectively, the time-domain indication information required for uplink scheduling is correspondingly generated. According to the time-frequency resources and time-domain indication information, the data reception and processing of each user equipment can effectively solve the management difficulties of uplink resource allocation and time reception in the continuous scheduling of different UEs in the case of multi-UE services, and greatly improve the uplink scheduling. efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a user equipment uplink scheduling method and device. Background technique [0002] With the development of communication technology, cellular-based Narrow Band Internet of Things (NB-IoT) is an emerging technology in the field of IoT. It is built on a cellular network and consumes only about 180KHz frequency band. System For Mobile Communications (Global Mobile Communications System) network, UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) network or LTE (Long Term Evolution, Long Term Evolution) network to reduce deployment costs and achieve smooth upgrades. NB-IoT has the advantages of low power consumption, wide coverage, low cost, and large capacity, and can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, smart parking, and smart agriculture. [0003] The downl...
