Basic service set resource reservation
Basic Service Set (BSS) resource reservation may be provided. BSS resource reservation may include determining a time window for a to accommodate a transmission of a target Station (STA) in a BSS, wherein the BSS further comprises one or more other STAs. An AP may then transmit a reservation scheduling frame, to claim access of a channel, inform the target STA of the time window, and reserve the channel for a duration defined by the time window.
1 . A method comprising:
determining a time window for an Access Point (AP) to accommodate a transmission of a target Station (STA) in a Basic Service Set (BSS), wherein the BSS further comprises one or more other STAs;
transmitting a reservation scheduling frame, to:
claim access of a channel,
inform the target STA of the time window, and
reserve the channel for a duration defined by the time window, wherein the reservation scheduling frame is a Medium Access Control (MAC) Protocol Data Unit (MPDU), wherein the MPDU comprises a header including a duration field that indicates a transmission time of the reservation scheduling frame and the duration defined by the time window; and
instructing each of the one or more other STAs of the BSS not to transmit during the time window.
2 . The method of claim 1 , wherein the reservation scheduling frame comprises a value setting a Network Allocation Vector (NAV), wherein the NAV indicates the duration defined by the time window.
3 . The method of claim 1 , wherein the MPDU comprises:
a body; and
a trailer.
4 . The method of claim 1 , wherein the reservation scheduling frame is included in an Aggregate-MPDU (A-MPDU).
5 . The method of claim 1 , further comprising:
setting an inter-BSS NAV to indicate the reservation of the channel for the duration.
6 . The method of claim 1 , further comprising:
locking-out an Enhanced Distributed Channel Access (EDCA) function before transmitting the reservation scheduling frame.
7 . The method of claim 1 , further comprising:
pre-polling at least a portion of the one or more other STAs to minimize Uplink (UL) contention.
8 . A system comprising:
a memory storage; and
a processing unit coupled to the memory storage, wherein the processing unit is operative to:
determine a time window for an Access Point (AP) to accommodate a transmission of a target Station (STA) in a Basic Service Set (BSS), wherein the BSS further comprises one or more other STAs; and
transmit a reservation scheduling frame, to:
claim access of a channel,
inform the target STA of the time window, and
reserve the channel for a duration defined by the time window, wherein the reservation scheduling frame is a Medium Access Control (MAC) Protocol Data Unit (MPDU), wherein the MPDU comprises a header including a duration field that indicates a transmission time of the reservation scheduling frame and the duration defined by the time window; and
instruct each of the one or more other STAs of the BSS not to transmit during the time window.
9 . The system of claim 8 , wherein the reservation scheduling frame comprises a value setting a Network Allocation Vector (NAV), wherein the NAV indicates the duration defined by the time window.
10 . The system of claim 8 , wherein the MPDU further comprises:
a body; and
a trailer.
11 . The system of claim 8 , wherein the reservation scheduling frame is included in an Aggregate-MPDU (A-MPDU).
12 . The system of claim 8 , wherein the processing unit is further operative to:
set an inter-BSS NAV to indicate the reservation of the channel for the duration.
13 . The system of claim 8 , wherein the processing unit is further operative to:
lock-out an Enhanced Distributed Channel Access (EDCA) function before transmitting the reservation scheduling frame.
14 . The system of claim 8 , wherein the processing unit is further operative to:
pre-poll at least a portion of the one or more other STAs to minimize Uplink (UL) contention.
15 . A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
determining a time window for an Access Point (AP) to accommodate a transmission of a target Station (STA) in a Basic Service Set (BSS), wherein the BSS further comprises one or more other STAs; and
transmitting a reservation scheduling frame, to:
claim access of a channel,
inform the target STA of the time window, and
reserve the channel for a duration defined by the time window, wherein the reservation scheduling frame is a Medium Access Control (MAC) Protocol Data Unit (MPDU), wherein the MPDU comprises a header including a duration field that indicates a transmission time of the reservation scheduling frame and the duration defined by the time window; and
instructing each of the one or more other STAs of the BSS not to transmit during the time window.
16 . The non-transitory computer-readable medium of claim 15 , wherein the reservation scheduling frame comprises a value setting a Network Allocation Vector (NAV), wherein the NAV indicates the duration defined by the time window.
17 . The non-transitory computer-readable medium of claim 15 , wherein the MPDU further comprises:
a body; and
a trailer.
18 . The non-transitory computer-readable medium of claim 15 , wherein the reservation scheduling frame is included in an Aggregate-MPDU (A-MPDU).
19 . The non-transitory computer-readable medium of claim 15 , wherein the method executed by the set of instructions further comprises:
setting an inter-BSS NAV to indicate the reservation of the channel for the duration.
20 . The non-transitory computer-readable medium of claim 15 , wherein the method executed by the set of instructions further comprises:
locking-out an Enhanced Distributed Channel Access (EDCA) function before transmitting the reservation scheduling frame.
