The transition zone is an area in which a path-loss is lower to the LPN than to the at least one neighboring node but a received DL power density is lower from the LPN than from the at least one neighboring node.

If the physical downlink control channel is detected, the terminal reports response information via a physical uplink control channel resource corresponding to the resource in which the physical downlink control channel was detected. If the enhanced physical downlink control channel is detected, the terminal reports via a prescribed physical uplink control channel resource.

Abstract: In various embodiments, a corpus of codecs may be correlated with different, partially overlapping ranges of transmission characteristics. As channel conditions degrade or improve, the system may select a new codec with which to continue the connection based upon the corresponding overlapping range. Codecs may not be switched immediately when the transmission characteristics enter overlapping ranges, to avoid degrading the user's experience. If the characteristics remain in the overlap, or manifest a likely progression toward another region, then the transition may be effected.
