Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for receiving or calculating an interference parameter based, at least in part, on one or more estimated power delay profiles (PDPs), one or more precoding rules, and one or more kernels, the one or more estimated PDPs being associated with one or more communication channels. The UE may receive a configuration for applying the interference parameter to a transmission having a power near a compression point of a power amplifier to reduce transmission non-linearities. Numerous other aspects are described.
Claims29
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, the one or more processors, individually or collectively and based at least in part on information stored in the one or more memories, being configured to:
- receive a configuration for receiving or calculating an interference parameter, indicative of an ergodic average of interference, based at least in part on one or more estimated power delay profiles (PDPs), one or more precoding rules, and one or more kernels, the one or more estimated PDPs being associated with one or more communication channels;
- receive the one or more precoding rules via radio resource control messaging;
- receive a selection of one of the multiple precoding rules via medium access control (MAC) control element (MAC-CE) messaging or downlink control information (DCI) messaging;
- and
- receive a configuration for applying the interference parameter to a transmission having a power near a compression point of a power amplifier to reduce transmission non-linearities.
An apparatus for wireless communication at a network node, comprising:
- one or more memories;
- and
- one or more processors, the one or more processors, individually or collectively and based at least in part on information stored in the one or more memories, being configured to:
- transmit, or configure a user equipment (UE) to calculate, an interference parameter, indicative of an ergodic average of interference, based at least in part on one or more estimated power delay profiles (PDPs), one or more precoding rules, and one or more kernels, the one or more estimated PDPs being associated with one or more communication channels;
- transmit the one or more precoding rules via radio resource control messaging;
- transmit a selection of one of the multiple precoding rules via medium access control (MAC) control element (MAC-CE) messaging or downlink control information (DCI) messaging;
- and
- configure the UE to apply the interference parameter to a transmission having a power near a compression point of a power amplifier to reduce transmission non-linearities.
