Embodiment Construction

[0051] The following disclosure provides many different embodiments or illustrations for implementing different features of the invention. The components and arrangements of particular examples are used in the following discussion to simplify the case. Any exemplifications discussed are for illustrative purposes only and do not in any way limit the scope and meaning of the invention or its exemplifications.

[0052] see figure 1 . figure 1 It is a schematic diagram of coverage extension level (CElevel) according to some embodiments of the present invention. Such as figure 1 As shown, in the LTE-evolved Internet of Things (eMTC) system, coverage extension levels are divided into Mode A and Mode B. Mode A is for better distance or channel quality, and does not require too many repeated transmissions. Mode B is for situations where the distance or channel quality is poor, requiring more repeated transmissions.

Abstract

The invention discloses a wireless communication method, a base station device and a base station system. The wireless communication method comprises the following steps of: measuring a plurality of quality parameters of a channel between a user device and the base station device by a processor; determining, by the processor, a corresponding coverage extension level of a plurality of coverage extension levels corresponding to the channel according to at least one of a bit error rate parameter and a block error rate parameter of the plurality of quality parameters, a reference signal received power parameter, and an interference parameter; and configuring, by the processor, a resource according to the corresponding coverage extension level for the UE to perform a first data uplink operation via the channel to upload uplink data to the base station device. When the method is used for classifying coverage extension levels, interference, a block error rate, a bit error rate and the like are all considered, so that the channel quality is actually reflected, the transmission error rate is effectively reduced, and the resource utilization rate is improved.

Description

technical field [0001] This case relates to a wireless communication method, base station device and base station system, especially the wireless communication method, base station device and base station system related to coverage extension levels. Background technique [0002] In Narrowband Internet of Things (NB-IoT) or LTE-based Internet of Things (eMTC), the coverage extension level is divided into multiple levels. For example, between the base station and the user device of the NB-IoT, the corresponding number of repeated message transmissions will be selected according to the coverage extension level. When selecting the coverage extension level, it is not enough to reflect the actual channel quality if only the distance, signal-to-noise ratio, reference signal received power, etc. are used for judgment. When the allocation of coverage extension levels is inappropriate, it will result in a high transmission error rate or waste a lot of wireless resources. Contents o...
