US 2023/0145901 A1 · LINK ERROR RECOVERY METHOD AND APPARATUS

Abstract

A link error recovery method applied to a transmitter MLD is provided. Links between the transmitter MLD and a receiver MLD include a first link and a second link, and one of the transmitter MLD and the receiver MLD has an STR capability while the other does not have the STR capability. The method includes: determining that transmission of a first PPDU on the first link fails; and transmitting a second PPDU to the receiver MLD at a first moment by using the first link, the second PPDU being used to retransmit an error part in the first PPDU. The first moment is a moment at which the transmitter MLD obtains transmission status information of the second link. Alternatively, the first moment is a moment for transmitting a next PPDU on the first link if the first PPDU is normally transmitted.

Dependent claims

A link error recovery method, wherein the method is applied to a transmitter multi-link device (MLD), links between the transmitter MLD and a receiver MLD comprise a first link and a second link, one of the transmitter MLD and the receiver MLD has a simultaneous transmitting and receiving (STR) capability while the other does not have the STR capability, and the method comprises:

determining, by the transmitter MLD, that transmission of a first physical protocol data unit (PPDU) on the first link fails;
and
transmitting, by the transmitter MLD, a second PPDU to the receiver MLD at a first moment through the first link, wherein the second PPDU comprises a retransmitted error part from the first PPDU, wherein
the first moment is a moment at which the transmitter MLD obtains transmission status information of the second link, and the transmission status information of the second link indicates that transmission of a third PPDU on the second link fails;
or the first moment is a moment for transmitting a next PPDU on the first link assuming that the first PPDU is normally transmitted.

2 more elements

A transmitter multi-link device (MLD), comprising:

at least one memory, configured to store computer instructions;
and
at least one processor, configured to perform the computer instructions to cause the transmitter MLD to:
determine that transmission of a first physical protocol data unit (PPDU) on a first link fails;
and
transmit a second PPDU to a receiver MLD at a first moment through the first link, wherein the second PPDU comprises a retransmitted error part from the first PPDU;
wherein the first moment is a moment at which the transmitter MLD obtains transmission status information of a second link, and the transmission status information of the second link indicates that transmission of a third PPDU on the second link fails;
or the first moment is a moment for transmitting a next PPDU on the first link assuming that the first PPDU is normally transmitted;
wherein the first link and the second link are links between the transmitter MLD and the receiver MLD, one of the transmitter MLD and the receiver MLD has a simultaneous transmitting and receiving (STR) capability while the other does not have the STR capability.

6 more elements

A non-transitory computer readable storage medium storing computer instructions, which when executed by at least one processor, cause a transmitter multi-link device (MLD) comprising the at least one processor to:

determine that transmission of a first physical protocol data unit (PPDU) on a first link fails;
and
transmit a second PPDU to a receiver MLD at a first moment through the first link, wherein the second PPDU comprises a retransmitted error part from the first PPDU;
wherein the first moment is a moment at which the transmitter MLD obtains transmission status information of a second link, and the transmission status information of the second link indicates that transmission of a third PPDU on the second link fails;
or the first moment is a moment for transmitting a next PPDU on the first link assuming that the first PPDU is normally transmitted;
wherein the first link and the second link are links between the transmitter MLD and the receiver MLD, one of the transmitter MLD and the receiver MLD has a simultaneous transmitting and receiving (STR) capability while the other does not have the STR capability.
