USER EQUIPMENT AND EVOLVED NODE-B AND METHODS FOR OPERATION IN A COVERAGE ENHANCEMENT MODE

摘要

Embodiments of a User Equipment (UE) and an Evolved Node-B (eNB) and methods for operating in a coverage enhancement (CE) mode are generally described herein. The UE may include hardware processing circuitry configured to determine a CE category for the UE based at least partly on downlink channel statistics related to reception of one or more downlink signals from an eNB. The CE category may reflect one of a level of additional link margin and a level of system resources for performance at or above a performance threshold. The hardware processing circuitry may be further configured to transmit, in physical random access channel (PRACH) frequency resources, a PRACH preamble according to an uplink access repetition number. The PRACH frequency resources and the uplink access repetition number may be based at least partly on the CE category for the UE.
