TLDR
In this article, a mobile station receives a downlink control structure in a first carrier, where the control structure indicates that control information for the mobile station is on a second, different carrier.Abstract:
A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specifies resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.read more

Method of transmitting and receiving control information based on spatial-multiplexing gain
TL;DR: In this paper, a control information transmission and reception method based on a spatial-multiplexing gain was proposed, where the common control information used for decoding the E-PDCCH was transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information.
