Methods and apparatus related to enhanced machine type communication

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the memory and the at least one processor being configured to:
• receive, from a base station via an anchor channel, information within at least one of a master information block or a system information block, the information indicating a subset of non-anchor channels selected from a set of available non-anchor channels having a bandwidth within an unlicensed frequency band, wherein the information indicating the subset of non-anchor channels identifies a set of channel groups from a plurality of channel groups, the subset of non-anchor channels corresponding to channels in the set of channel groups;
• and
• transmit data on at least one non-anchor channel of the subset of non-anchor channels.

A method of wireless communication at a base station, comprising:

• selecting a subset of non-anchor channels from a set of available non-anchor channels, wherein the subset of non-anchor channels corresponds to a bandwidth within an unlicensed frequency band;
• forming a plurality of channel groups;
• and
• transmitting information within at least one of a master information block or a system information block on an anchor channel, the information indicating a set of channel groups of the plurality of channel groups, wherein the subset of non-anchor channels corresponds to channels in the set of channel groups.
