Channel mapping in shared spectrum in the presence of higher tier users

Abstract

Techniques and apparatus for channel mapping in shared spectrum in the presence of higher tier users are provided. One technique includes evaluating, for different channel locations of orthogonal channel(s) within available spectrum, an amount of transmission limitation imposed to a group of devices due to incumbent protection, an amount of available bandwidth, and/or a maximum contiguous channel size. A channel location is assigned to each orthogonal channel, based on the evaluation. Another technique includes determining first channel location(s) in order to assign at least a first orthogonal channel within available spectrum. Each first orthogonal channel is associated with a group of devices sharing bandwidth within one or more networks. An exchange is participated in with a network entity to share a first set of information associated with the first channel locations. A determination is made whether to modify portion(s) of the first set of information, based on the exchange.

What is claimed is: 
     
         1 . A method for wireless communication by a first network entity, comprising:
 determining one or more first channel locations to assign at least a first channel within available spectrum, wherein each first channel is associated with a group of devices sharing bandwidth within one or more networks;   participating in an exchange with at least a second network entity to share a first set of information associated with the first channel locations; and   determining whether to modify at least a portion of the first set of information, based on the exchange.   
     
     
         2 . The method of  claim 1 , wherein participating in the exchange further comprises receiving, from the second network entity, a second set of information associated with second channel locations determined by the second network entity to assign to at least a second channel within the available spectrum. 
     
     
         3 . The method of  claim 2 , wherein the at least first channel within the available spectrum and the at least second channel within the available spectrum are orthogonal channels. 
     
     
         4 . The method of  claim 2 , wherein the determination is to refrain from modifying the first set of information if there is not a conflict between the first set of information and the second set of information. 
     
     
         5 . The method of  claim 2 , wherein the determination is to modify at least the portion of the first set of information if there is a conflict between the first set of information and the second set of information, the method further comprising modifying at least the portion of the first set of information based on the determination. 
     
     
         6 . The method of  claim 5 , wherein:
 the first set of information comprises at least one of the first channel locations, a first coverage overlap graph used to determine a first number of networks in the one or more networks that have overlapping coverage, or a number of the at least first channel; and   the second set of information comprises at least one of the second channel locations, a second coverage overlap graph used to determine a second number of networks in the one or more networks that have overlapping coverage, or a number of the at least second channel.   
     
     
         7 . The method of  claim 6 , wherein the modifying comprises modifying the first channel locations if there is a conflict between the first channel locations from the first set of information and the second channel locations from the second set of information. 
     
     
         8 . The method of  claim 6 , wherein the modifying comprises modifying the at least first channel if the number of the at least first channel from the first set of information is different than the number of the at least second channel from the second set of information. 
     
     
         9 . The method of  claim 6 , wherein the modifying comprises modifying the first coverage overlap graph if at least a part of the first coverage overlap graph is different from the second coverage overlap graph. 
     
     
         10 . An apparatus for wireless communications, comprising:
 at least one processor configured to:

 the determination is to modify at least the portion of the first set of information if there is a conflict between the first set of information and the second set of information; and   the at least one processor is further configured to modify at least the portion of the first set of information based on the determination.
