Method for receiving data and communication device

A method for receiving data, comprising:

• (a) receiving a plurality of packages according to a sliding window W(N) having been slid for N times, N is a positive integer, the W(N) corresponds to a plurality of block sequence numbers (BSNs), both the packages and a plurality of counters all correspond to the BSNs to which the W(N) corresponds;
• (b) sliding the W(N) to a W(N+1) if a starting package of the packages is received successfully;
• (c) activating the counter corresponding to a non-starting package for counting if the non-starting package of the packages is received successfully;
• (d) rewiring a plurality of count label values indicating whether each of the counting values of the counters has achieved an up-limited value to obtain a rewired time-out table if the starting package of the packages is not received successfully and part of the counters counts to the up-limited value, wherein the rewired time-out table has a plurality of first groups each having a first group values, and the first group values form a group time-out table;
• (e) rewiring a plurality of acknowledge label values indicating whether the packages are received successfully to obtain a rewire acknowledge table if the starting package of the packages is not received successfully and part of the counting values of the counters has achieved the up-limited value, wherein the rewire acknowledge table has a plurality of second groups each having a second group value, and the second group values forms a group acknowledge table;
• (f) sliding the W(N) to the W(N+1) according to the group time-out table and the group acknowledge table;
• and
• (g) continuously receiving another plurality of packages according to the W(N+1).

A communication device, comprising:

• a receiver used for receiving a plurality of packages according to a sliding window W(N) having been slid for N times, wherein N is a positive integer, the W(N) corresponds to a plurality of block sequence numbers (BSNs), both the packages and a plurality of counters all correspond to the BSNs to which the W(N) corresponds;
• wherein the receiver further slides the W(N) to a W(N+1) if the receiver successfully receives a starting package of the packages;
• wherein the receiver further activates the counter corresponding to a non-starting package for counting if the receiver successfully receives the non-starting package of the packages;
• wherein the receiver further slides the W(N) to the W(N+1) if the receiver does not successfully receive the starting package of the packages and part of the counters counts to an up-limited value;
• wherein the receiver further continuously receives another plurality of packages according to the W(N+1) and determines whether the BSNs to which the counters correspond is located in the overlap area between the W(N) and the W(N+1);
• wherein when at least one BSN to which at least one counter among the counters corresponds is not located in the overlap area, the receiver further resets the at least one counter corresponding to the at least one BSN not located in the overlap area, and each of the at least one counter corresponding to the at least one BSN not located in the overlap area corresponds to another BSN.
