Neighbor relations for disproportional/dissimilar bandwidth/carrier allocation

A communications system comprising:

• a first device including:
• a first receiver;
• and
• a first processor configured to:
• operate the first device to receive first channel assignment information indicating a first channel assignment to a first cell, said first channel assignment being an assignment to a new channel;
• check the first channel assignment information to determine if the first channel assignment is a dissimilar channel assignment which differs from a previous channel assignment in at least one of bandwidth or carrier frequency;
• operate the first device to request existing neighbor list information corresponding to the first cell with the dissimilar channel assignment in response to said checking determining that the first channel assignment is a dissimilar channel assignment;
• operate the first device to receive neighbor list information, said neighbor list information including at least a neighbor list of a first neighbor of said first cell;
• and
• generate updated neighbor list information for one or more cells, said step of generating updated neighbor list information for one or more cells including generating at least some neighbor list supplemental information for the neighbor list of the first neighbor of the first cell.

A non-transitory computer readable medium including machine executable instruction which when executed by a processor of a first device, control the first device to perform the steps of:

• receiving first channel assignment information indicating a first channel assignment to a first cell, said first channel assignment being an assignment to a new channel;
• checking the first channel assignment information to determine if the first channel assignment is a dissimilar channel assignment which differs from a previous channel assignment in at least one of bandwidth or carrier frequency;
• in response to said checking determining that the first channel assignment is a dissimilar channel assignment, requesting existing neighbor list information corresponding to the first cell with the dissimilar channel assignment;
• receiving neighbor list information, said neighbor list information including at least a neighbor list of a first neighbor of said first cell;
• and
• generating updated neighbor list information for one or more cells, said step of generating updated neighbor list information for one or more cells including generating at least some neighbor list supplemental information for the neighbor list of the first neighbor of the first cell.
