Robust channel reservation on a shared communication medium
First Claim
1. A communication method, comprising:
- contending for access to a communication medium shared between a competing Radio Access Technology (RAT) and a primary RAT;
encoding a first portion of a channel reservation message defined by the competing RAT with a transmission opportunity duration associated with the primary RAT;
encoding a second portion of the channel reservation message with the transmission opportunity duration;
encoding the second portion of the channel reservation message with an operator identifier associated with the primary RAT; and
transmitting, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending,wherein the transmission opportunity duration in the first portion is decodable by devices of the competing RAT but is not decodable by devices of the primary RAT,wherein the transmission opportunity duration in the second portion is decodable by the devices of the competing RAT and by the devices of the primary RAT, andwherein the encoding of the second portion comprises;
selecting a duration for the channel reservation message based on the transmission opportunity duration, the operator identifier, or a combination thereof; and
setting a length field of the channel reservation message based on the selected duration.

Abstract
Techniques for managing channel reservation on a shared communication medium are disclosed. An access point or an access terminal contending for access to a communication medium shared between a first Radio Access Technology (RAT) and a second RAT, for example, may encode a first portion of a channel reservation message defined by the first RAT with a transmission opportunity duration associated with the second RAT and also encode a second portion of the channel reservation message with the transmission opportunity duration. The access point or the access terminal may then transmit, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending.

13. A communication apparatus, comprising:
-
at least one processor; at least one memory, the at least one processor and the at least one memory being configured to; contend for access to a communication medium shared between a competing Radio Access Technology (RAT) and a primary RAT, encode a first portion of a channel reservation message defined by the competing RAT with a transmission opportunity duration associated with the primary RAT, encode the second portion of the channel reservation message with an operator identifier associated with the primary RAT, and encode a second portion of the channel reservation message with the transmission opportunity duration; and a transceiver configured to transmit, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending, wherein the transmission opportunity duration in the first portion is decodable by devices of the competing RAT but is not decodable by devices of the primary RAT, wherein the transmission opportunity duration in the second portion is decodable by the devices of the competing RAT and by the devices of the primary RAT, and wherein the at least one processor and the at least one memory are configured to encode the second portion by; selecting a duration for the channel reservation message based on the transmission opportunity duration, the operator identifier, or a combination thereof; and setting a length field of the channel reservation message based on the selected duration. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 24)

22. A communication apparatus, comprising:
-
means for contending for access to a communication medium shared between a competing Radio Access Technology (RAT) and a primary RAT; means for encoding a first portion of a channel reservation message defined by the competing RAT with a transmission opportunity duration associated with the primary RAT; means for encoding a second portion of the channel reservation message with the transmission opportunity duration; means for encoding the second portion of the channel reservation message with an operator identifier associated with the primary RAT; and means for transmitting, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending, wherein the transmission opportunity duration in the first portion is decodable by devices of the competing RAT but is not decodable by devices of the primary RAT, wherein the transmission opportunity duration in the second portion is decodable by the devices of the competing RAT and by the devices of the primary RAT, and wherein the means for encoding of the second portion comprises; selects a duration for the channel reservation message based on the transmission opportunity duration, the operator identifier, or a combination thereof, and sets a length field of the channel reservation message based on the selected duration. - View Dependent Claims (23, 25, 26, 27, 28)

29. A non-transitory computer-readable medium comprising code, which, when executed by at least one processor, causes the at least one processor to perform operations for communication, the non-transitory computer-readable medium comprising:
-
code for contending for access to a communication medium shared between a competing Radio Access Technology (RAT) and a primary RAT; code for encoding a first portion of a channel reservation message defined by the competing RAT with a transmission opportunity duration associated with the primary RAT; code for encoding a second portion of the channel reservation message with the transmission opportunity duration; code for encoding the second portion of the channel reservation message with an operator identifier associated with the primary RAT; and code for transmitting, over the communication medium, the channel reservation message including the first and second portions to reserve the communication medium based on the contending, wherein the transmission opportunity duration in the first portion is decodable by devices of the competing RAT but is not decodable by devices of the primary RAT, wherein the transmission opportunity duration in the second portion is decodable by the devices of the competing RAT and by the devices of the primary RAT, and wherein the code for encoding of the second portion comprises; code for selecting a duration for the channel reservation message based on the transmission opportunity duration, the operator identifier, or a combination thereof; and code for setting a length field of the channel reservation message based on the selected duration. - View Dependent Claims (30, 31, 32, 33, 34)
