Information Processing Method and Method for UE Random Accessing LTE System

摘要

The information processing method includes: an evolved NodeB sending information of PRACH resources configured for a UE to the UE via a PDSCH indicated by a downlink control channel, and after receiving a random access preamble sequence sent from the UE, the evolved NodeB sending downlink control information and a Random Access Response (RAR), wherein the downlink control channel is an enhanced Physical Downlink Control Channel (ePDCCH); or, information carried by PBCH indicates that the downlink control channel is the ePDCCH or a physical downlink control channel; or, when the LTE system bandwidth is less than or equal to the reception bandwidth of the UE, the downlink control channel is a physical downlink control channel, and when the LTE system bandwidth is larger than the reception bandwidth of the UE, the downlink control channel is the ePDCCH.

1. An information processing method, wherein the method comprises:
an evolved nodeB (eNodeB) sending information of a physical random access channel (PRACH) resource configured for a user equipment to the UE through a physical downlink shared channel (PDSCH) indicated by a downlink control channel; wherein the downlink control channel is an enhanced physical downlink control channel (ePDCCH); or information carried in a physical broadcast channel (PBCH) indicates that the downlink control channel is the ePDCCH or a physical downlink control channel; or, when a Long Term Evolution (LTE) system bandwidth is less than or equal to a reception bandwidth of the UE, the downlink control channel is a physical downlink control channel, when the LTE system bandwidth is greater than the reception bandwidth of the UE, the downlink control channel is the ePDCCH.
