Abstract  Abstract

The invention generally claims for operating in the coverage enhancement (CE) mode an embodiment of user equipment (UE) and an evolved Node B (eNB). the UE comprises a hardware processing circuit the hardware processing circuit is configured downlink channel statistics is based at least in part on the received one or more downlink signal from the eNB to determine CE of the category of the UE. CE category can reflect the performance reaches or is higher than the performance threshold of system resource level and one of the additional link margin level. the hardware processing circuit may also be configured to uplink access repeat number in a physical random access channel (PRACH) frequency resource to send the PRACH preamble. PRACH frequency resource and an uplink access repeat number based at least in part on CE category of the UE.

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.
