System and method for searching for a control channel

摘要

A method performed at a base station and a corresponding method performed at a station receiving a transmission from the base station. The methods relate to signaling the station as to a number of PDCCH information that is included in the transmission so the station may terminate a search when the station has identified the PDCCHs in the transmission. The method performed by the station includes receiving the transmission that includes at least one PDCCH information, each PDCCH information having a respective mapped downlink control information (DCI). The method further includes detecting one of the PDCCH information in the transmission and determining lengths of information bits of the DCI and the PDCCH information. The method also includes terminating a search for a further one of the PDCCH information when a first type of padding is used for the mapping of the DCI over the PDCCH information based on the lengths.

1. A method, comprising:
at a station:
receiving a transmission from a base station of a network, the transmission including at least one control channel information, each control channel information having a respective downlink control information (DCI) mapped thereover;detecting one of the control channel information in the transmission;determining whether carrier aggregation is activated and cross-carrier scheduling is configured for the station;determining whether a length of information bits of the DCI is less than a length of the information bits of the control channel information when the carrier aggregation is activated and the cross-carrier scheduling is configured; andterminating a search for a further one of the control channel information when the length of information bits of the DCI is less than the length of information bits of the control channel information and a first type of padding is used for the mapping of the DCI over the control channel information.
