Abstract
Methods and apparatus for parameter (e.g., timing) adjustment in a wireless network. In one embodiment, the timing adjustment includes detection and compensation for one or more missed adjustment messages. In one variant, for certain designated events, a client device may ignore a timer expiration, and apply a previously stored timing advance (TA) command. For example, a user equipment (UE) will determine if a TA command has been missed during a measurement gap interval (such as e.g., to perform measurements on an unsynchronized network), and reuse the previous TA command value. Reusing the TA command value introduces negligible error, which can be corrected in existing error correction capabilities (e.g., OFDM cyclic prefixes, etc.).
