Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may support use of separate precoding matrices, among other parameters, while the UE is operating in a half duplex mode or a full duplex mode, or a combination thereof. For example, the UE may determine a first precoding matrix associated with wireless communication (e.g., downlink, uplink) when in a half duplex mode during a first portion of a transmission time interval (TTI), and determine a second precoding matrix to use for the wireless communication when in a full duplex mode during a second portion of the TTI. The second precoding matrix may be different from the first precoding. The UE may, as a result, perform the wireless communication based on the second precoding matrix when in the full duplex mode during the second portion of the TTI.
