Abstract
A method of wireless communication includes detecting uplink interference in a received uplink transmission of a user equipment. The received uplink transmission is padded with noise based on the detected interference and also based on a frequency domain partition, whether a subframe is protected, and/or a user equipment type.
Claims22
A method of wireless communication, comprising:
- detecting, by a base station, uplink interference in a first portion of a received uplink transmission of a user equipment (UE);
- and
- noise padding a second portion of the received uplink transmission to reduce interference variation between the first portion and the second portion based on the detected uplink interference and based on at least one of a frequency domain partition, whether a subframe is protected, and user equipment type, wherein the second portion of the received uplink transmission is different than the first portion of the received uplink transmission.
A method for virtual noise padding in a wireless communication, comprising:
- detecting, by a base station, uplink interference in a first portion of an uplink transmission;
- calculating an increased interference for a second portion of the uplink transmission based on the detected uplink interference;
- and
- directly signaling to a user equipment (UE) at least one of a power control command and a rate control command in response to the calculated interference to reduce interference variation between the first portion and the second portion, wherein the second portion of the received uplink transmission is different than the first portion of the received uplink transmission.
