Abstract
Aspects of the present disclosure provide a manner of avoiding excessive latency and resource consumption due to exhaustive beam searching and pairing for finding an appropriate bi-directional beam pair combination with manageable mutual interference to enable point-to-point FD transmission. Aspects of the present disclosure also provide a solution for enabling multi-user transmission where one or all UEs are with FD capability and the cross-UE interference raised from FD transmission are measured and taken into account during multi-user pairing.
Claims20
A method comprising:
- receiving, by an apparatus, configuration information comprising a set of candidate beams;
- transmitting, by the apparatus, a reference signal (RS) on a first beam identified in the set of candidate beams;
- measuring, by the apparatus, interference signal strength of the RS on a second beam identified in the set of candidate beams;
- determining, by the apparatus, self-interference status for the first and second beams based on the measured interference strength signal;
- selecting an apparatus transmit and apparatus receive beam pair from the set of candidate beams based on the determined self-interference status;
- and
- transmitting, by the apparatus to a base station, identification of the apparatus transmit and apparatus receive beam pair.
An apparatus comprising:
- a processor;
- and
- a computer-readable medium, having stored thereon computer executable instructions, that when executed cause the apparatus to:
- receive configuration information comprising a set of candidate beams;
- transmit a reference signal (RS) on a first beam identified in the set of candidate beams;
- measure interference signal strength of the RS on a second beam identified in the set of candidate beams;
- determine self-interference status for the first and second beams based on the measured interference strength signal;
- select an apparatus transmit and apparatus receive beam pair from the set of candidate beams based on the determined self-interference status;
- and
- transmit to a base station identification of the apparatus transmit and apparatus receive beam pair.
A computer-readable storage medium having stored thereon computer-executable instructions, that when executed by a processor, cause the processor to:
- receive configuration information comprising a set of candidate beams;
- transmit a reference signal (RS) on a first beam identified in the set of candidate beams;
- measure interference signal strength of the RS on a second beam identified in the set of candidate beams;
- determine self-interference status for the first and second beams based on the measured interference strength signal;
- select transmit and receive beam pair from the set of candidate beams based on the determined self-interference status;
- and
- transmit identification of the apparatus transmit and apparatus receive beam pair.
