Abstract
Aspects of the present disclosure provide an apparatus and techniques for wireless communication. A node (e.g., a BS or UE) may receive information regarding a configuration of at least one subframe for measuring mixed interference between the node and one or more nodes in a network. The configuration specifies a pattern for measuring reference signals by the node within the at least one subframe. The node may measure reference signals according to the pattern, and determine interference between the node and the one or more nodes, based on the measured reference signals.
Claims26
A method for wireless communication by a user equipment (UE), comprising:
- receiving information regarding a configuration of at least one subframe for measuring mixed interference between the UE and one or more other UEs in a network, the configuration specifyinga first pattern for measuring first reference signals from the one or more other UEs within the at least one subframe and a second pattern for transmitting second reference signals to the one or more other UEs within the at least one subframe, wherein the first pattern for measuring first reference signals indicates at least a first set of time slots within the at least one subframe for receiving the first reference signals and the second pattern for transmitting second reference signals indicates at least a second set of time slots within the at least one subframe for transmitting the second reference signals;
- measuring the first reference signals from the one or more other UEs within the at least one subframe according to the first pattern;
- transmitting the second reference signals to the one or more other UEs within the at least one subframe according to the second pattern, wherein the first reference signals are of a same type as the second reference signals;
- and
- determining interference between the UE and the one or more other UEs, based on the measured first reference signals.
