Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may transmit, in a time-frequency resource occasion to a second wireless communication device, a first orbital angular momentum (OAM) signal in a first OAM mode. The first wireless communication device may receive, in the time-frequency resource occasion from the second wireless communication device, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal. Numerous other aspects are described.
Claims30
A first wireless communication device for wireless communication, comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more memories and the one or more processors, individually or collectively configured to:
- receive, from a network node, an indication indicating a first circle index of a first multi-circle transceiver and a first orbital angular momentum (OAM) mode for transmitting OAM signals;
- transmit, in a time-frequency resource occasion to a second wireless communication device and using antennas of a first circle of the first multi-circle transceiver, a first OAM signal in the first OAM mode;
- and
- receive, in the time-frequency resource occasion from the second wireless communication device and using antennas of a second circle of the first multi-circle transceiver, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal, wherein the first circle has a different radius than the second circle.
A method of wireless communication performed by a first wireless communication device, comprising:
- receiving, from a network node, an indication indicating a first circle index of a first multi-circle transceiver and a first orbital angular momentum (OAM) mode for transmitting OAM signals;
- transmitting, in a time-frequency resource occasion to a second wireless communication device and using antennas of a first circle of the first multi-circle transceiver, a first OAM signal in the first OAM mode;
- and
- receiving, in the time-frequency resource occasion from the second wireless communication device and using antennas of a second circle of the first multi-circle transceiver, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal, wherein the first circle has a different radius than the second circle.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that when executed by one or more processors of a first wireless communication device, cause the first wireless communication device to:
- receive, from a network node, an indication indicating a first circle index of a first multi-circle transceiver and a first orbital angular momentum (OAM) mode for transmitting OAM signals;
- transmit, in a time-frequency resource occasion to a second wireless communication device and using antennas of a first circle of the first multi-circle transceiver, a first OAM signal in the first OAM mode;
- and
- receive, in the time-frequency resource occasion from the second wireless communication device and using antennas of a second circle of the first multi-circle transceiver, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal, wherein the first circle has a different radius than the second circle.
An apparatus for wireless communication at a first wireless communication device, comprising:
- means for receiving, from a network node, an indication indicating a first circle index of a first multi-circle transceiver and a first orbital angular momentum (OAM) mode for transmitting OAM signals;
- means for transmitting, in a time-frequency resource occasion to a second wireless communication device and using antennas of a first circle of the first multi-circle transceiver, a first OAM signal in the first OAM mode;
- and
- means for receiving, in the time-frequency resource occasion from the second wireless communication device and using antennas of a second circle of the first multi-circle transceiver, a second OAM signal, in a second OAM mode, that is orthogonal to the first OAM signal, wherein the first circle has a different radius than the second circle.
