Embodiment Construction

[0030] The detailed description relates to enhanced signaling of transmission settings or parameters for post-processing of wireless communications, such as fifth generation wireless new radio (5G NR) systems. Enhanced signaling of transmission settings or parameters for post-processing may be used for high frequency and / or "narrow" beam communications to achieve improved transmission efficiency for wireless communications. Signaling enhancements may include transmitting device confirmation of nonlinear distortion information for improved post-processing, such as digital post-distortion (DPoD) processing. Improved post-processing can enable transmissions to be transmitted with greater power efficiency.

[0031]Traditionally, wireless networks such as LTE and 5G utilize digital predistortion (DPD) processing and address nonlinear distortion and its effects, such as in-band and out-of-band interference, at the transmitter. Alternatively, some systems may employ user equipment (...

Abstract

In one aspect, a method for wireless communication includes transmitting a first message indicating a precoding matrix identifier configured to identify a particular precoding matrix for precoding at least one future transmission by another wireless communication device; and receiving a second message indicating information regarding whether the particular precoding matrix has been or will be used for at least one future transmission. In another aspect, a method for wireless communication includes receiving a first message indicating a precoding matrix identifier configured to identify a particular precoding matrix for precoding at least one future transmission by a wireless communication device; and transmitting a second message indicating information regarding whether the particular precoding matrix has been or will be used for precoding the at least one future transmission. Other aspects and features are also claimed and described.
