Abstract
Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving, via a plurality of input ports, one or more input signals carrying information via one or more input ports of the plurality of input ports, transforming, via a mapping module each of the one or more input signals into two or more output signals carrying the information, amplifying the two or more output signals, and transmitting, coherently, the amplified two or more output signals in a multiple-in multiple-out (MIMO) network.
Claims26
A method of wireless communication by a repeater in a network, comprising:
- receiving, via one or more of a plurality of input ports, one or more input signals carrying information;
- mapping, via a mapping module, one or more of the plurality of input ports to a subset of a plurality of output ports based on feedback information associated with a plurality of output beam sweep procedures;
- transforming, via the mapping module, each of the one or more input signals into two or more output signals carrying the information;
- amplifying the two or more output signals;
- adjusting, via the mapping module, phases of at least one of the two or more output signals such that the two or more output signals are coherently phased when received by a receiver;
- and
- transmitting, via the subset of the plurality of output ports, the two or more output signals in a multiple-in multiple-out (MIMO) network.
A repeater, comprising:
- a plurality of input ports configured to receive one or more input signals carrying information via one or more input ports of the plurality of input ports;
- a mapping module configured to:
- map the one or more of the plurality of input ports to a subset of a plurality of output ports based on feedback information associated with a plurality of output beam sweep procedures;
- and
- transform each of the one or more input signals into two or more output signals carrying the information;
- and
- a plurality of output ports configured to:
- amplify the two or more output signals,
- adjust, via the mapping module, phases of at least one of the two or more output signals such that the two or more output signals are coherently phased when received by a receiver;
- and
- transmit, via the subset of the plurality of output ports, the two or more output signals in a multiple-in multiple-out (MIMO) network.
A repeater, comprising:
- means for receiving, via one or more of a plurality of input ports, one or more input signals carrying information;
- means for mapping, via a mapping module, one or more of the plurality of input ports to a subset of a plurality of output ports based on feedback information associated with a plurality of output beam sweep procedures;
- means for transforming, via the mapping module, each of the one or more input signals into two or more output signals carrying the information;
- means for amplifying the two or more output signals;
- means for adjusting, via the mapping module, phases of at least one of the two or more output signals such that the two or more output signals are coherently phased when received by a receiver;
- and
- means for transmitting, via the subset of the plurality of output ports, the two or more output signals in a multiple-in multiple-out (MIMO) network.
A non-transitory computer readable medium having instructions that, when executed by a processor of a repeater, causes the processor to:
- cause a plurality of input ports to receive one or more input signals carrying information via one or more input ports of the plurality of input ports;
- cause a mapping module to:
- map the one or more of the plurality of input ports to a subset of a plurality of output ports based on feedback information associated with a plurality of output beam sweep procedures;
- and
- transform each of the one or more input signals into two or more output signals carrying the information;
- cause a plurality of power amplifiers to amplify the two or more output signals;
- cause the mapping module to adjust phases of at least one of the two or more output signals such that the two or more output signals are coherently phased when received by a receiver;
- and
- cause a plurality of output ports to transmit, via the subset of the plurality of output ports, the two or more output signals in a multiple-in multiple-out (MIMO) network.
