APPARATUS, SYSTEMS AND METHODS FOR USER EQUIPMENT (UE) COVERAGE ENHANCEMENT LEVEL DEFINITION, SELECTION AND ALLOCATION

摘要

Systems, apparatus, methods, computer program products and the like provide for updating the CE (Coverage Enhancement)-level of a User Terminal/Equipment (UE). The UE may be a NB-IoT (Narrow Band Internet of Things) device, a MTC (Machine Type Communication) device or any other device supporting CE. Embodiments of the invention implement UE selection/re-selection of random access resources and/or base station definition of CE configuration, allocation and/or re-allocation of resources between CE levels.

主权项

1. A method for selecting a Coverage Enhancement (CE) level from a plurality of CE levels, the method comprising:
determining, by a User Equipment (UE), a matching Coverage Enhancement (CE) level from a plurality of CE levels matching the UE; determining, by the UE, that the matching CE level is not defined in a CE configuration or has no available allocated Physical Random Access Channel (PRACH) resources; determining, by the UE, a new CE level from the plurality of CE levels, wherein the new CE level is the next highest available CE level from the plurality of CE levels; and transmitting, by the UE, using the determined new CE level.
