Embodiment Construction

[0026] The detailed description set forth below in conjunction with the drawings is intended as a description of various configurations, and is not intended to represent the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. However, it is obvious to those skilled in the art that these concepts can be practiced without these specific details. In some cases, to avoid obscuring these concepts, well-known structures and components are shown in the form of block diagrams.

[0027] Several aspects of the telecommunication system will now be presented with reference to various devices and methods. These devices and methods will be described in the following detailed description, and illustrated by various blocks, components, circuits, processes, algorithms (collectively referred to as "elements"), etc. in the drawings. These elements can be implemented ...

Abstract

An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving, at UE, a random access response including a first signal via a first physical channel and a second signal via a second physical channel from a base station (BS), generating a connection request based on the random access response, estimating a carrier to interference plus noise ratio (CINR) ofa random-access channel based on at least one the first signal or the second signal, and sending a message including the CINR and the connection request to the BS in response to the random access response.

Description

[0001] Cross references to related applications [0002] This application requires the U.S. Provisional Application No. 62 / 634,583, filed on February 23, 2018, entitled "Efficient Method of DL-CINR Measurement and Reporting in NB IOT", and the title of " Efficient Method of DL-CINR Measurement and Reporting in NBIOT" US Patent Application No. 16 / 273,904 priority, these two applications are expressly incorporated by reference in their entire contents. Technical field [0003] Aspects of the present disclosure generally relate to wireless communication networks, and more specifically, to devices and methods for measuring and reporting conditions such as carrier-to-interference plus noise ratio (CINR) by narrowband Internet of Things user equipment (NB-IoT UE). Background technique [0004] Wireless communication networks are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multi...
