Abstract
Buffer indication signaling during seamless roaming may be provided. A serving access point (AP) establishes one or more links with a client device, wherein the client device is configured to roam from the serving AP to a target AP. The serving AP transmits buffered downlink (DL) data to the client device during a roaming transition from the serving AP to the target AP. The serving AP determines that the buffered DL data for the client device has been transmitted to the client device and transmits to the client device buffer indication signaling indicating that the serving AP has delivered the buffered DL data for the client device.
Claims20
A method comprising:
- establishing, by a serving access point (AP), one or more links with a client device, wherein the client device is configured to roam from the serving AP to a target AP;
- transmitting, by the serving AP, buffered downlink (DL) data to the client device during a roaming transition from the serving AP to the target AP;
- determining, by the serving AP, that the buffered DL data for the client device has been transmitted to the client device;
- and
- transmitting, by the serving AP to the client device, buffer indication signaling indicating that the serving AP has delivered the buffered DL data for the client device.
A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- establish one or more links with a client device, wherein the client device is configured to roam to a target AP;
- transmit buffered downlink (DL) data to the client device during a roaming transition to the target AP;
- determine that the buffered DL data for the client device has been transmitted to the client device;
- and
- transmit, to the client device, buffer indication signaling indicating that the buffered DL data for the client device has been delivered.
A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method comprising:
- establishing one or more links with a client device, wherein the client device is configured to roam to a target AP;
- transmitting buffered downlink (DL) data to the client device during a roaming transition to the target AP;
- determining that the buffered DL data for the client device has been transmitted to the client device;
- and
- transmitting, to the client device, buffer indication signaling indicating that the buffered DL data for the client device has been delivered.
