20130039290 | Method and System for Uplink Control Channel Transmit Diversity Using Multiple Downlink Control Channel Based Resource Allocation - A method and network element for allocating uplink resources for hybrid automatic repeat request acknowledgement at a user equipment (UE), the method indicating a first set of uplink resources to the user equipment; and indicating a first subset of the first set of uplink resources that the UE may transmit upon using a position of a first downlink control channel (DCCH) scheduling a downlink shared channel (DSCH) on a cell. Further, a method at a user equipment (UE) for receiving an allocation of uplink resources for HARQ acknowledgement, the method receiving a first set of uplink resources; deriving a first subset of uplink resources that the UE may transmit upon using downlink control information bits within a first downlink control channel on a primary cell, and deriving a second subset of the first set of uplink resources that the UE may transmit upon within a second downlink control channel. | 02-14-2013 |
