METHOD AND SYSTEM FOR MILLIMETER WAVE HOTSPOT (mmH) BACKHAUL AND PHYSICAL (PHY) LAYER TRANSMISSIONS

Abstract

A method and apparatus are disclosed for communication in a Millimeter Wave Hotspot (mmH) backhaul system which uses mesh nodes. A mmH mesh node may receive a control signal which includes a total number of available control slots. The mesh node may determine the number of iterations of a resource scheduling mechanism that can be made during the time period of all available control slots, based on the number of neighbor nodes for the mesh node. Further, the mesh node may receive control slot information, including information about traffic queues and priorities. The mesh node may then perform resource scheduling using the resource scheduling mechanism based on the currently received control slot information and control slot information received in previous iterations of resource scheduling. The mesh node may also adjust a preamble based on a time between a last packet transmission and a current packet transmission to a neighboring node.

What is claimed is: 
     
         1 . A station (STA) comprising:
 a processor configured to:
 encode a payload using a Long low-density parity check code (LDPC) code word; 
 insert an indicator within a physical layer (PHY) header of a packet, wherein the indictor corresponds to a length of the LDPC code word; and 
   a transmitter configured to transmit the packet.   
     
     
         2 . The STA of  claim 1 , wherein the indicator comprises a forward error correction (FEC) indicator. 
     
     
         3 . The STA of  claim 1 , wherein the indicator indicates one of a long, short, or other specific length. 
     
     
         4 . The STA of  claim 1 , wherein the transmitter is configured to transmit the packet to a neighboring node. 
     
     
         5 . A method comprising:
 encoding a payload using a Long low-density parity check code (LDPC) code word;   inserting an indicator within a physical layer (PHY) header of a packet, wherein the indictor corresponds to a length of the LDPC code word; and   transmitting the packet.   
     
     
         6 . The method of  claim 5 , wherein the indicator comprises a forward error correction (FEC) indicator. 
     
     
         7 . The method of  claim 5 , wherein the indicator indicates one of a long, short, or other specific length. 
     
     
         8 . The method of  claim 5 , wherein transmitting the packet comprises transmitting to a neighboring node. 
     
     
         9 . A station (STA) comprising:
 a receive antenna configured to receive a plurality of discovery messages, each discovery message comprising a respective beam index and a respective response offset;   a processor configured to determine an optimal discovery message from the plurality of discovery messages, the optimal discover message comprising an optimal beam index and an optimal response offset; and   a transmit antenna configured to transmit a feedback transmission, wherein the feedback transmission is transmitted after a duration of the optimal respond offset and comprises a characteristic corresponding to the optimal beam index.   
     
     
         10 . The STA of  claim 9 , wherein the optimal beam index comprises an identifier for a beam being transmitted. 
     
     
         11 . The STA of  claim 9 , wherein each response offset comprises an offset, in time units, to the next beacon response interval (BRI) available for transmission of the feedback transmission. 
     
     
         12 . The STA of  claim 11 , wherein each BRI is split into slots separated by a Long Inter-Frame Spacing (LIFS). 
     
     
         13 . The STA of  claim 9 , wherein the characteristic corresponding to the beam index is at least one of a direction or a slot.
