Embodiment Construction

[0041] As described above, the UE identifies new cells and performs measurements on them. For example, the identified cell may be a serving cell or a neighboring cell. The existing methods of the measurement process described above have certain drawbacks. For example, for NB-IoT, the existing measurement procedure using CRS may not work well because the UE bandwidth is reduced to only 1 PRB. This means that the number of resource elements available for measurement is significantly reduced, which affects both measurement accuracy and measurement time / rate. Furthermore, a NB-IoT UE may be capable of two or more modes of operation (eg, standalone, guard-band, and in-band modes of operation). This may further affect the UE's measurement process. Therefore, NB-IoT requires new measurements.

[0042] The present disclosure contemplates various embodiments that may address these and other deficiencies associated with existing approaches to measurement procedures in NB-IoT. In so...

Abstract

Methods in nodes (405A, 410A) are disclosed. The method includes obtaining (504) information related to the mode of operation of the first cell (415B) to be measured by the node. The method includes selecting (508) a measurement procedure from a plurality of possible measurement procedures based on the obtained information related to the mode of operation of the first cell, wherein one or more measurement parameters of the selected measurement procedure are suitable for the first cell mode of operation. The method includes performing (512) one or more measurements in the first cell using the selected measurement procedure.

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly to regulating measurement procedures for the narrowband Internet of Things. Background technique [0002] Machine-to-machine (M2M) communication (or Machine Type Communication (MTC) or Internet–of-Things (IoT)) is used to establish communication between devices and between devices and people. Communications may, for example, include data exchanges, signaling, measurement data, configuration information, and other suitable types of communications. The device size may vary from the size of a wallet to the size of a base station. IoT devices may be used for applications such as sensing environmental conditions (eg, temperature readings), metering or measurement (eg, power usage, etc.), fault finding, error detection, and other suitable applications. In these applications, depending on the type of service (e.g. ~200ms every 2 seconds, ~500ms every 60 minutes, etc.)...
