Abstract
Wireless devices may communicate with each other, for example, via sidelink. A wireless device may request reference signals from another wireless device to determine a new beam to prevent beam failure of wireless communications. A base station may send beam information for sidelink communications to assist a wireless device in recovering from a beam failure.
Claims18
A method comprising:
- receiving, by a first wireless device, a beam failure recovery threshold for wireless communications between the first wireless device and a second wireless device;
- based on a determination that a channel quality associated with the wireless communications fails to satisfy the beam failure recovery threshold, sending, to a base station, a message comprising:
- an indication of a beam failure recovery of the wireless communications;
- and
- an identifier of the second wireless device;
- receiving, from the base station and based on the message, an indication of a reference signal;
- and
- receiving, via the wireless communications and based on the reference signal, at least one transport block from the second wireless device.
5 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by one or more processors, cause the wireless device to:
- receive a beam failure recovery threshold for wireless communications between the wireless device and a second wireless device;
- based on a determination that a channel quality associated with the wireless communications fails to satisfy the beam failure recovery threshold, sending, to a base station, a message comprising:
- an indication of a beam failure recovery of the wireless communications;
- and
- an identifier of the second wireless device;
- receive, from the base station and based on the message, an indication of a reference signal;
- and
- receive, via the wireless communications and based on the reference signal, at least one transport block from the second wireless device.
8 more elements
One or more non-transitory computer readable media storing instructions that, when executed cause:
- receiving a beam failure recovery threshold for wireless communications between a first wireless device and a second wireless device;
- based on a determination that a channel quality associated with the wireless communications fails to satisfy the beam failure recovery threshold, sending, to a base station, a message comprising:
- an indication of a beam failure recovery of the wireless communications;
- and
- an identifier of the second wireless device;
- receiving, from the base station and based on the message, an indication of a reference signal;
- and
- receiving, via the wireless communications and based on the reference signal, at least one transport block from the second wireless device.
