Abstract
Certain aspects of the present disclosure provide techniques for accounting for potential increased interference caused by MU-MIMO transmissions by applying a first set of one or more criteria configured to limit transmit power in a first direction, when a wireless node is operating in an SU-MIMO mode; and applying a second set of one or more criteria configured to limit transmit power in the first direction, when the wireless node is operating in an MU-MIMO mode.
Claims20
An apparatus for wireless communication, comprising:
- at least one memory comprising computer-executable instructions;
- and
- one or more processors configured to execute the computer-executable instructions and cause the apparatus to:
- apply a first set of one or more criteria configured to limit transmit power in a first direction, when the apparatus is operating in a single-user (SU) multiple-input multiple-output (MIMO) mode;
- and
- apply a second set of one or more criteria configured to limit transmit power in the first direction, when the apparatus is operating in a multi-user (MU) MIMO mode.
A method for wireless communication at a wireless node, comprising:
- applying a first set of one or more criteria configured to limit transmit power in a first direction, when the wireless node is operating in a single-user (SU) multiple-input multiple-output (MIMO) mode;
- and
- applying a second set of one or more criteria configured to limit transmit power in the first direction, when the wireless node is operating in a multi-user (MU) MIMO mode.
A network entity, comprising:
- at least one transceiver, at least one memory comprising computer-executable instructions;
- and one or more processors configured to execute the computer-executable instructions and cause the network entity to:
- transmit via the at least one transceiver in a single-user (SU) multiple-input multiple-output (MIMO) mode, subject to a first set of one or more criteria configured to limit transmit power in a first direction;
- and
- transmit via the at least one transceiver in a multi-user (MU) MIMO mode, subject to a second set of one or more criteria configured to limit transmit power in the first direction.
