Abstract
Techniques and structures are provided to support a short-NAV type wireless medium reservation scheme in a network that utilizes adaptive modulation techniques.
Claims31
A method for use during a wireless frame exchange in a wireless network, comprising:
- receiving a first wireless frame from a remote network device, said first wireless frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device;
- determining an actual data rate to use to transmit user data to said remote network device;
- and
- when said actual data rate does not allow an entire data MAC protocol data unit (MPDU) to be transmitted in a data frame within said medium reservation period, fragmenting said data MPDU to identify a first fragment that can be transmitted in a data frame within said medium reservation period.

A method comprising:
- receiving a first wireless frame from a remote network device, said first wireless frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device;
- determining a data rate to use to transmit user data to said remote network device;
- determining a number of data MAC protocol data units (MPDUs) that can be aggregated within a wireless frame at said data rate for transmission to said remote network device within said medium reservation period;
- and
- transmitting a second wireless frame to said remote network device that includes said number of data MPDUs.
2 more elements
An apparatus comprising:
- a wireless transceiver to support wireless communication with one or more remote wireless entities;
- and
- a baseband processing subsystem, coupled to said wireless transceiver, to perform baseband processing and control functions, wherein said baseband processing subsystem is operative to (a) receive a first frame from a remote network device during a wireless frame exchange, said first frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device, (b) determine an actual data rate to use to transmit user data to said remote network device, and (c) when said actual data rate does not allow an entire MAC protocol data unit (MPDU) to be transmitted in a subsequent frame within said medium reservation period, fragment said data MPDU to achieve a first fragment that can be transmitted in a subsequent frame within said medium reservation period.
An apparatus comprising:
- a wireless transceiver to support wireless communication with one or more remote wireless entities;
- and
- a baseband processing subsystem, coupled to said wireless transceiver, to perform baseband processing and control functions, said baseband processing subsystem to:
- (a) receive a first frame from a remote network device during a wireless frame exchange, said first frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device, (b) determine an actual data rate to use to transmit user data to said remote network device, (c) determine a number of MAC protocol data units (MPDUs) that can be aggregated within a wireless frame at said data rate for transmission to said remote network device within said medium reservation period, and (d) cause a second frame to be transmitted to said remote network device, said second frame including said number of MPDUs.

An article comprising a storage medium having instructions stored thereon that, when executed by a computing platform, operate to:
- receive a first wireless frame from a remote network device, said first wireless frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device;
- determine an actual data rate to use to transmit user data to said remote network device;
- determine a number of MAC protocol data units (MPDUs) that can be aggregated within a wireless frame at said data rate for transmission to said remote network device within said medium reservation period;
- and
- transmit a second wireless frame to said remote network device, said second wireless frame including said number of MPDUs.
2 more elements
A system comprising:
- at least one dipole antenna;
- a wireless transceiver, coupled to said at least one dipole antenna, to support wireless communication with one or more remote wireless entities;
- and
- a baseband processing subsystem, coupled to said wireless transceiver, to perform baseband processing and control functions, wherein said baseband processing subsystem is operative to:
- (a) receive a first frame from a remote network device during a wireless frame exchange, said first frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device, (b) determine a data rate to use to transmit user data to said remote network device, (c) determine a number of MAC protocol data units (MPDUs) that can be aggregated within a wireless frame at said data rate for transmission to said remote network device within said medium reservation period, and (d) cause a second wireless frame to be transmitted to said remote network device, said second wireless frame including said number of MPDUs.
