Claim:
A method comprising: receiving a control channel in a receiver path of a device over a link comprising a plurality of series of slots that are interlaced; determining that a control message for said device occupies two or more of said plurality of series of slots based, at least in part, on a detected presence of a control channel preamble in each of said two or more series of slots; determining that at least one of said plurality of series of slots is not occupied by said control message based, at least in part, on a detected absence of said control channel preamble in said at least one of said plurality of series of slots; and subsequently enabling operation of one or more circuits in a receiver path of said device during a first time corresponding to at least said two or more of said plurality of series of slots, and disabling said operation of one or more circuits in said receiver path during a second time corresponding to at least a portion of said at least one of said plurality of series of slots.
