Abstract
A method for parallel communication with wireless local area network (WLAN) receivers is described. A parallel transmission is started. A first MAC protocol data unit (MPDU) is sent to a first WLAN receiver. An acknowledgment (ACK) request is sent to the first WLAN receiver. An ACK is received from the first WLAN receiver.
Claims31
A method for parallel communication with wireless local area network (WLAN) receivers, the method being implemented by a wireless device, the method comprising:
- sending a first medium access control (MAC) protocol data unit (MPDU) to a first WLAN receiver;
- sending a second MPDU to a second WLAN receiver in parallel to the first MPDU;
- and
- including, in a MAC header of the first MPDU, instructions to the first WLAN receiver that comprise an acknowledgement policy for the first WLAN receiver.
A wireless device that is configured for parallel communication with wireless local area network (WLAN) receivers, comprising:
- a processor;
- and
- circuitry coupled to said processor configured to:
- send a first medium access control (MAC) protocol data unit (MPDU) to a first WLAN receiver;
- send a second MPDU to a second WLAN receiver in parallel to the first MPDU;
- and
- include, in a MAC header of the first MPDU, instructions to the first WLAN receiver that comprise an acknowledgement policy for the first WLAN receiver.
An apparatus that is configured for spatial division multiple access (SDMA) communication with wireless local area network (WLAN) receivers, comprising:
- means for sending a first medium access control (MAC) protocol data unit (MPDU) to a first WLAN receiver, wherein a MAC header of the MPDU comprises a method of acknowledgment for the first WLAN receiver;
- means for sending a second MPDU to a second WLAN receiver in parallel to the first MPDU;
- means for sending an acknowledgment (ACK) request to the first WLAN receiver;
- and
- means for receiving an ACK from the first WLAN receiver.
A computer-program product for spatial division multiple access (SDMA) communication with wireless local area network (WLAN) receivers, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:
- code for sending a first medium access control (MAC) protocol data unit (MPDU) to a first WLAN receiver, wherein a MAC header of the MPDU comprises a method of acknowledgment for the first WLAN receiver;
- code for sending a second MPDU to a second WLAN receiver in parallel to the first MPDU;
- code for sending an acknowledgment (ACK) request to the first WLAN receiver;
- and
- code for receiving an ACK from the first WLAN receiver.
A method for parallel communication with wireless local area network (WLAN) receivers, the method comprising:
- sending a Power Save Multi-Poll (PSMP) frame indicating a Power Save Multi-Poll Downlink Transmission Time (PSMP-DTT) and a Power Save Multi-Poll Uplink Transmission Time (PSMP-UTT);
- sending a first MAC protocol data unit (MPDU) to a first WLAN receiver indicating a PSMP acknowledgement (ACK) policy, wherein the PMSP ACK policy is indicated in a MAC header of the MPDU;
- sending a second MPDU to a second WLAN receiver in parallel to the first MPDU;
- and
- receiving a Multicast Traffic Identifier Block ACK (MTBA) frame from the first WLAN receiver during the PSMP-UTT.
