A method for a UE reporting a CQI comprising steps of: obtaining a total
number M of CQI report sub-bands in a system and a number N of CQI report sub-
bands needed to be reported; measuring channel qualities of all sub-bands and
according to the measurement result, determining N CQI report sub-bands needed
to be reported and corresponding CQI values; sending a L-bit long sequence to
a base station for indicating the sub-bands that need to be reported; sending
CQI values corresponding to the sub-bands needed to be reported to the base
station. The present invention uses comparatively shorter bit sequence to
indicate CQI report sub-bands needed to be reported and reduces the number of
information bits necessary for CQI report sub-bands and also reduces the
number of information bits corresponding to the CQI values in the CQI report
sub-bands.

A method and a UE apparatus for radio resource management in a mobile communication system. When a discontinuous reception period or an inactivity period of a UE exceeds a threshold, an ENB releases resources for uplink control information transmission allocated to the UE, and the UE recognizes the release of the resources and stops transmitting the uplink control information through the resources. This reduces the explicit reconfiguration procedure through an RRC message, which is otherwise necessary whenever the UE enters a new discontinuous reception mode.

A method and apparatus for multiplexing positive or negative acknowledgement
signals (ACK or NACK, respec-tively)

serving base station (Node B) during a CQI
transmission time interval (TTI) in a single-carrier frequency division

each of the possible orthogonal covers applied at the UE transmitter. For
robust system performance, absence of ACK/NACK

The present invention supposes a situation in which an Enhanced Uplink Dedicated transport Channel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system. In a user equipment (UE), when physical channels for transmitting EUDCH data are transmitted in addition to existing physical channels, a Peak-to-Average Power Ratio (PAPR) of an uplink transport signal increases. The increase in PAPR depends upon Orthogonal Variable Spreading Factor (OVSF) codes allocated to the corresponding physical channels and in-phase/quadrature-phase (I/Q) channels. Therefore, the present invention proposes an apparatus and method for allocating optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.

Time synchronization in a wireless communication system comprises transmitting a synchronization frame from a transmitter to a receiver over a wireless communication medium. The synchronization frame includes a timestamp indicating the transmitter local time when a symbol at a predefined position of the synchronization frame is placed on the wireless communication medium for transmission. The synchronization frame is received at the receiver which determines a receiving time comprising the receiver local time when said symbol of the synchronization frame was received at the physical layer of the receiver. Time synchronizing is performed by determining a difference between said timestamp and said receiving time, and adjusting the receiver local time based on said difference to time synchronize the receiver with the transmitter.
