The link quality reporting method includes measuring link quality for received radio blocks, and if there is a modulation scheme with a largest number of radio blocks, reporting link quality for the modulation scheme, and if there is a plurality of schemes with the same number of radio blocks, reporting link quality for a modulation scheme selected using a predetermined method. Performance deterioration can be minimized in a link adaptation process.

Method of requesting and reporting link quality in an EGPRS2 system

To report channel quality in RTTI configuration, channel quality parameters for at least one radio block intended for the MS is calculated over a filtering period. A filtering period is two times longer than the time needed to transmit the radio block.

Method of reporting channel quality in EGPRS system

A method and an apparatus of performing a cell reselection procedure in a wireless communication system are provided. The method includes starting a first reselection timer if a signal property value of a first neighbor cell with a higher priority than a serving cell is increased to above a threshold, starting a first delay timer if a second reselection timer that is a reselection timer of a second neighbor cell with a higher priority than the first neighbor cell is running at the expiry of the first reselection timer, reselecting the second neighbor cell as a suitable cell if the second reselection timer expires before the expiry of the first delay timer, and reselecting the first neighbor cell as the suitable cell if the first delay timer expires before the expiry of the second reselection timer.

Method and apparatus of performing cell reselection procedure in wireless communication system

A method and apparatus for an enhanced general packet radio service (EGPRS) system is provided. A plurality of temporary block flows (TBFs) are established or reconfigured. If fast ACK/NACK reporting (FANR) activation for one TBF is inconsistent with FANR activation for another TBF, the allocated TBFs are aborted.

Method and apparatus for handling abnormal situation in EGPRS system

A method of enabling a mobile station (MS) to request radio resources for uplink packet transmission is provided. The method includes starting a supervision timer at the beginning of a packet access procedure, the packet access procedure initiated by scheduling the sending of a packet channel request message and performing cell re-selection when the supervision timer expires, wherein the supervision timer is stopped when any message is received from a network in response to the packet channel request message or after M+1 (M&#x2267;0) attempts to send the packet channel request message.

Method for requesting radio resources for uplink packet transmission in GPRS system

A method of controlling a transmit power includes determining a power control parameter of an assigned timeslot, wherein the value of the power control parameter is a default value if the assigned timeslot is assigned with no power control parameter and the value of the power control parameter is the current value if the assigned timeslot is already used by the mobile station and determining the transmit power on an uplink channel.

Method of controlling transmit power in wireless communication system

There is provided a method of enabling a mobile station to report channel quality in a wireless communication system. The method includes receiving a radio block allocated for a control block, the control block having a header and a control message, the header having an identifier, measuring channel quality for the radio block allocated for the control block when the identifier identifies the mobile station, and reporting the channel quality. A mobile station can report channel quality for its own control block.

A data transmission method for a MIMO (Multiple-input Multiple-Output) system allowing multiple terminals to share channelization codes according to the channel states, by receiving channel information from terminals, allocating channelization codes for each transmit antenna based upon the received channel information, and transmitting data via each transmit antenna according to the allocated channelization codes. When there are many user terminals and if the number of channelization codes are limited, namely, when the total number of channel codes used to distinguish the terminals is less than the total number of terminals, channelization code sharing per transmit antenna among multiple terminals is performed, such that the throughput of data that can be sent by using each channelization code is increased.
