Abstract
A method for transmitting, to one or more wireless stations in a wireless network, map information identifying resources allocated to one or more of the wireless stations, the map information including a plurality of Maps, each Map allocating resources to one or more of the wireless stations, one or more of the Maps including a Next Map Pointer (NSP) that includes location information identifying a location of the next Map within a frame.
Claims27
A method comprising:
- transmitting, to one or more wireless stations in a wireless network,
- map information identifying resources allocated to one or more of the wireless stations, the map information including a plurality of Maps, each Map allocating resources to one or more of the wireless stations, one or more of the Maps including a Next Map Pointer (NSP) that includes location information identifying a location of the next Map within a frame.
An apparatus comprising:
- a controller;
- and
- a wireless transmitter coupled to the controller, the wireless transmitter configured to transmit, to one or more wireless stations in a wireless network, map information identifying resources allocated to one or more of the wireless stations, the map information including a plurality of Maps, each Map allocating resources to one or more of the wireless stations, one or more of the Maps including a Next Map Pointer (NSP) that includes location information identifying a location of the next Map within a frame.
A method comprising:
- receiving a Map indicating an allocation of resources to a wireless station;
- decoding the received Map;
- determining a physical transmission mode for the Map based on the decoding of the Map;
- receiving data via the allocated resources as indicated by the decoded Map;
- decoding and/or demodulating the received data using a same physical transmission mode used to decode the received Map, wherein the same physical transmission mode is used to transmit both the Map and the received data.
