A connection state DRX configuration method and device

Abstract

The invention relates to the field of communication, and discloses a connection state DRX configuration method and a connection state DRX configuration device, which are used for ensuring the accuracyof analyzing control information by a user and improving the scheduling efficiency of a base station. The method comprises the following steps that: the base station configures a DRX period as an integral multiple of an NPDCCH period; Then, the starting point of each NPDCCH cycle is used as a reference starting point, the distance between each reference starting point and the corresponding alternative starting point is calculated, and the alternative starting point corresponding to the distance with the minimum value is selected as the starting point of the activation period in one DRX cycle.Thus, the base station can schedule the terminal as soon as possible under the condition that downlink data exist, and scheduling conflicts with other follow-up terminals are reduced as much as possible while service surface time delay is reduced. And on the other hand, the condition that the NPDCCH cannot be correctly analyzed due to insufficient repetition times can be avoided, and the normal service of the terminal is ensured.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for configuring DRX in a connected state. Background technique [0002] In recent years, the mobile Internet has shown a rapid development trend, and the narrowband Internet of Things has broad market application prospects due to its deep coverage and long battery life. Narrow Band Internet of Things (hereinafter referred to as NB-IoT) is a global protocol standard for deep coverage and low power consumption proposed by 3GPP, which has attracted widespread attention in the industry. [0003] In order to achieve the goal of deep coverage and low power consumption, NB-IoT adopts many targeted technologies, among which Discontinuous Reception (DRX) is a key item to help terminals achieve power saving in the connected state. [0004] First, briefly introduce the power saving mechanism of DRX. Normally, the terminal will continuously monitor the physical dow...

Problems solved by technology

[0019] refer to Figure 4 As shown, this scenario will cause DRX OnDuration to fail to include a complete NPDCCH cycle, which will lead to insufficient NPDCCH repetitions when the terminal performs NPDCCH detection in DRX OnDuration, which may cause the terminal to fail to detect NPDCCH correctly, thereby affecting the normal service of the terminal
