A method for managing a non-volatile memory is provided. The non-volatile memory has a number of blocks, and each block has a number of sub-blocks. The method includes a number of steps. First, a last physical address is obtained. The last physical address corresponds to a sub-block which is close to another sub-block where data is newly stored. Next, it is determined, for each sub-block of at least one block, the validity of data being stored. The at least one block is at least one neighboring block of a block containing the corresponding sub-block of the last physical address. Then, a mapping table is produced according to the step of determining the validity of data.

A signal detecting method and a receiver using the same are provided. The method includes the following steps. A receiving signal vector y is received through a number of channels, wherein the receiving signal vector y corresponds to a transmitting signal vector x transmitted by at least one of the channels.

A method is provided for a device in a wireless communication network including a base station. The method includes sending a sleep mode request to the base station; and receiving a sleep mode response including negotiating parameters from the base station. The method also includes entering a sleep mode determined by a single power saving class applicable to all traffic conditions between the device and the base station; and communicating with the base station based on the sleep mode. Further, the single power saving class is used to define a frame structure for configuring frames to form alternating listening windows and sleep windows, to define an initial sleep window, and to define a default listening window.
