Abstract
Abstract A communication system includes a shared channel occupied by a plurality of user equipments (UEs) and spread with a plurality of channelization codes to transmit user data, and a plurality of control channels for transmitting control information related to the shared channel in order to enable the UEs to receive the shared channel signal. The system generates a plurality of control channel sets by classifying the control channels into a predetermined number of control channels, and assigns the control channel sets so that each of the UEs monitors a particular control channel set among the control channel sets. Upon detecting necessity to modify a control channel set to be assigned to a particular UE among the UEs, a Node B determines to modify a control channel set assigned into the UE to a new control channel set at a predetermined point of time to come. After determining to modify the control channel set, the Node B transmits an indicator indicating expected modification of the control channel set and information on the control channel set to be modified to the UE over a downlink.

The method of claim 31 , wherein the step (b) further comprises the step of waiting retransmission of corresponding user data upon determining that the third buffer has user data to be transmitted if a sequence number of user data to be transmitted from the first buffer is greater by a predetermined value or over than a sequence number of user data stored in the third buffer.
Claim 47
Dependent Claim
86 words
The method of claim 31 , further comprising the step of comparing, by the UE receiving the status information, a sequence number of user data to be retransmitted from the second buffer with a sequence number stored in the third buffer and processing user data stored in the third buffer according to the comparison result, if a sequence number of user data to be transmitted from the first buffer is grater by a predetermined value or over than the sequence number stored in the third buffer.
Claim 48
Dependent Claim
66 words
The method of claim 34 , wherein the UE delivers the user data stored in the third buffer to an upper layer upon determining that an error has occurred in the third buffer, if there exists a sequence number which belongs to sequence numbers of user data to be transmitted from the second buffer but does not belong to sequence numbers stored in the third buffer.
Claim 49
Dependent Claim
55 words
The method of claim 34 , wherein the UE delivers the user data stored in the third buffer to an upper layer, if there exists a sequence number which does not belong to sequence numbers of user data to be transmitted from the second buffer but belongs to sequence numbers stored in the third buffer.
Claim 50
Independent Claim
194 words
An apparatus for transmitting status information of a first buffer and a second buffer in a communication system in which a Node B assigns a sequence number to user data in transmission order and includes the first buffer for storing the transmitted user data in transmission order and the second buffer for storing data to be retransmitted out of the transmitted user data, and a user equipment (UE) includes a third buffer for storing user data received from the Node B according to a sequence number of the received user data, the apparatus comprising: a Node B transmitter for transmitting the status information of a sequence number of user data to be transmitted from the first buffer and a sequence number of user data to be transmitted from the second buffer, for a transmission time interval (TTI) following a current point of time; and a UE receiver for receiving the status information and comparing a sequence number of user data to be transmitted from the first buffer with a sequence number of user data stored in the third buffer, and processing the user data stored in the third buffer according to the comparison result.
Claim 51
Independent Claim
194 words
An apparatus for transmitting status information of a first buffer and a second buffer in a communication system in which a Node B assigns a sequence number to user data in transmission order and includes the first buffer for storing the transmitted user data in transmission order and the second buffer for storing data to be retransmitted out of the transmitted user data, and a user equipment (UE) includes a third buffer for storing user data received from the Node B according to a sequence number of the received user data, the apparatus comprising: a Node B transmitter for transmitting the status information of a sequence number of user data to be transmitted from the first buffer and a sequence number of user data to be transmitted from the second buffer, for a transmission time interval (TTI) following a current point of time; and a UE receiver for receiving the status information and comparing a sequence number of user data to be transmitted from the first buffer with a sequence number of user data stored in the third buffer, and processing the user data stored in the third buffer according to the comparison result.
Claim 52
Dependent Claim
65 words
The method of claim 37 , wherein the UE receiver delivers the user data stored in the third buffer to an upper layer upon determining that an error has occurred in the third buffer if a sequence number of user data to be transmitted from the first buffer is less than or equal to a sequence number of user data stored in the third buffer.
Claim 53
Dependent Claim
62 words
The method of claim 37 , wherein the UE receiver waits retransmission of corresponding user data upon determining that the third buffer has user data to be transmitted if a sequence number of user data to be transmitted from the first buffer is greater by a predetermined value or over than a sequence number of user data stored in the third buffer.
