Embodiment Construction

[0063] The term UE (User Equipment) is used herein for illustrative purposes. This is meant to include any applicable wireless communication device (eg, MTC device, C-MTC device, mobile station (MS), etc.).

[0064] The term "network node" is used herein to denote one or more related network entities. This is meant to include any applicable network entities (e.g., 4G evolved Node B (eNodeB, eNB), 3G Node B (NB), 3G Radio Network Controller (RNC), 2G Base Station (BS), 2G Base Station Controller ( BSC) etc.).

[0065] The term "measurement gap" refers herein to a gap, the purpose of which is to allow the UE to temporarily suspend communication with the serving cell and tune to other carriers (frequencies) possibly belonging to other radio access technologies to perform measurements (e.g. search, detect and / or monitor neighboring cells). For example, such gaps may include (but are not limited to) 4G measurement gaps, 3G FDD transmission gaps (aka compressed mode gaps), 3G TDD...

Abstract

A method a wireless communication device and a corresponding method for a network node of a cellular communication system are disclosed. The network node and the wireless communication device are configured to communicate with each other according to an automatic repeat request (ARQ) protocol having a requirement that a number of time units between reception of an ARQ packet and transmission of anassociated response message is smaller than a maximum response time. According to the methods, the wireless communication device transmits at least one measurement gap adaptation signal to the network node. The network node determines a measurement gap configuration of the wireless communication device based on the measurement gap adaptation signal, wherein measurement gaps of the measurement gapconfiguration have a length smaller than the maximum response time. The network node transmits an indication of the measurement gap configuration to the wireless communication device, which uses themeasurement gap configuration to perform measurements. Corresponding computer program product, arrangements, network node and wireless communication device are also disclosed.

Description

technical field [0001] The present invention generally relates to the field of performing measurements in cellular communication systems. More specifically, it concerns the configuration of measurement gaps used to perform such measurements. Background technique [0002] Some applications and services provided through the use of cellular communication networks may be limited by both low latency requirements and high reliability (robustness) requirements. [0003] Examples of such applications and services can be illustrated in terms of mission critical MTC (Machine Type Communication) devices (hereinafter also referred to as C-MTC devices). [0004] Mission-critical MTC devices are used for communication, for example involving manufacturing, process industry, automotive and medical applications. Mission-critical MTC devices need to be more efficient than before in traditional communication systems (e.g., according to 2nd Generation-2G (e.g. GSM-Global System for Mobile Com...
