Downlink control information format design for wireless communication

摘要

Certain aspects present methods for designing a downlink control information (DCI) message that may be transmitted in a downlink channel such as a physical downlink control channel (PDCCH). The proposed DCI message supports uplink enhancements such as clustered single input multiple output (SIMO) operation.

1. A method for wireless communications by a base station, comprising:
selecting a downlink control information (DCI) format for conveying information about an uplink operation to a user equipment (UE) based on a transmission mode of the UE, such that a DCI format selected for conveying information about a clustered single input multiple output (SIMO) uplink transmission mode has a property of being a same size as a DCI format selected for conveying information about a non-clustered uplink transmission; generating a DCI message in accordance with the selected DCI format; and transmitting the DCI message.
