Mixed size expression peer discovery in WWAN

An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:

• means for determining a second set of resource block pairs on which to transmit a peer discovery message in a second time cycle based on a mapping of a first set of resource block pairs in a first time cycle to the second set of resource block pairs in the second time cycle, the mapping being a one-to-one mapping between each resource block pair in the first set of resource block pairs to a corresponding resource block pair in the second set of resource block pairs, resource block pairs in the first set of resource block pairs being in adjacent allocated resources;
• and
• means for transmitting the peer discovery message in the determined second set of resource block pairs, wherein the peer discovery message is transmitted with information indicating a message that is based on an order of a particular resource block pair within the second set of resource block pairs.

A non-transitory computer-readable medium storing computer executable code, comprising code for:

• determining a second set of resource block pairs on which to transmit a peer discovery message in a second time cycle based on a mapping of a first set of resource block pairs in a first time cycle to the second set of resource block pairs in the second time cycle, the mapping being a one-to-one mapping between each resource block pair in the first set of resource block pairs to a corresponding resource block pair in the second set of resource block pairs, resource block pairs in the first set of resource block pairs being in adjacent allocated resources;
• and
• transmitting the peer discovery message in the determined second set of resource block pairs, wherein the peer discovery message is transmitted with information indicating a message that is based on an order of a particular resource block pair within the second set of resource block pairs.
