METHODS TO ENHANCE NEIGHBOR PDCCH DECODING BY EXPLOITING CORRELATION OF RNTIS

摘要

Network identifiers used for control information are typically correlated in time. This correlation in time may be leveraged to reduce the control space searched, and thus the number of blind decodes performed by a UE during blind decoding of neighbor cell control information. An apparatus that exploits this correlation in time decodes a control channel transmitted by a neighbor cell to obtain a current network identifier used to perform an operation on the control channel transmission, compares the current network identifier with a set of network identifiers obtained from previously decoded control channels transmitted from the neighbor cell, and determines if the decoded control channel is valid based at least in part on the comparison. The set of network identifiers may be a list of network identifiers, or a range of network identifiers. The set of network identifiers may further include aggregation level information and frequency of occurrence information.

1. A method of wireless communication of a user equipment, comprising:
decoding a control channel transmitted by a neighbor cell to obtain a current network identifier used to perform an operation on the control channel transmission; determining if the current network identifier satisfies a network-identifier criterion; and applying a validation algorithm when the current network identifier satisfies the network-identifier criterion, wherein the validation algorithm determines if the decoded control channel was successfully decoded based on measurements of a data region corresponding to control information in the decoded control channel.
