各态样提供了控制被配置成根据利用重复传讯的通讯模式支援与用户设备之通讯的无线通讯网路中之用户设备操作之方法、以及可操作而执行那些方法之电脑程式产品及网路节点。一种方法包含下列步骤：决定该用户设备将使用之一调变及编码机制；识别该用户设备将配合该调变及编码机制而实施之一重复机制；以及将该被决定之调变及编码机制及被识别之重复机制的一指示传送到该用户设备。各态样认知：在一网路内实施一覆盖增强区时，可为CE-MTC UE界定固定的重复等级。可由一网路实施那些固定的重复等级，且那些固定的重复等级认知CE-MTC UE无线电状况间之差异。亦即，被使用之重复次数可对应于机器类型通讯装置所经历的无线电状况，因而在不良覆盖区中之那些装置将被选择成接收比在较佳无线电覆盖区中之那些装置的次数多的次数之重复。此种重复等级之粒度可能取决于特定营运商对覆盖增强区的实施方式。该第一态样认知：可针对在一网路存取节点支援的覆盖增强区中操作之用户设备实施不同的重复等级。可在诸如eNodeB等的网路存取节点上配置那些不同的重复等级。; computer program products and network nodes operable to perform those methods. One method comprises: determining a modulation and coding regime to be used by the user equipment; identifying a repetition regime to be implemented by the user equipment in conjunction with the modulation and coding regime; and communicating an indication of the determined modulation and coding regime and identified repetition regime to the user equipment. Aspects recognise that when implementing a coverage enhanced region within a network it is possible that fixed repetition levels can be defined for CE-MTC UE. Those fixed repetition levels can be implemented by a network and recognise differences between the CE-MTC UE radio condition. That is to say, the number of repetitions used may correspond to radio condition being experienced at a machine-type communication device: those in poorer coverage regions will be selected to receive a greater number of repetitions than those in a better radio coverage region. The granularity of such repetition levels may subject to a given operator’s implementation of a coverage enhanced region. The first aspect recognises that it is possible to implement varying repetition levels for user equipment operating in the coverage enhanced region supported by a network access node. Those varying repetition levels can be configured at the network access node; for example, an eNodeB.
