An apparatus and method in which an Enhanced Uplink Dedicated transport CHannel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system is provided. 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 apparatus and method allocate optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.

An interleaving method to which time-first-mapping is applied for a plurality of channel-coded and rate-matched code blocks considering a modulation scheme in a mobile communication system is provided. The interleaving method includes determining sizes of a horizontal area and a vertical area of an interleaver memory, selecting a defined number of adjacent coded symbols in a same code block according to a modulation scheme, generating modulation groups in a vertical direction, sequentially writing the modulation groups in the horizontal area on a row-by-row basis, and sequentially reading the symbols written in the interleaver memory on a column-by-column basis.

A method and apparatus for estimating the radio link status between all MS and a BS in a wireless communication system are provided, in which the MS and the BS make the same decision as to the radio link status. The method and apparatus provide a radio link status estimation procedure suitable for a Packet-Switched network system. Thus, when each of an MS and a BS detects errors in its radio link status, it notifies the other party of the poor radio link status, thereby preventing an unnecessary MS or BS operation and saving radio resources.

An interleaving method to which time-first-mapping is applied in a mobile communication system is provided. The interleaving method includes writing coded bits into an interleaver on a row-by-row basis, and reading the coded bits written in the interleaver on a column-by-column basis, wherein the coded bits are written by groups having a size according to a modulation order

A method for configuring gain factors in a WCDMA telecommunication system is provided in which the gain factor for defining power required for normal reception of uplink data in an environment supporting an uplink service over an E-DCH can be configured using minimal signaling information. First gain factors for first TFs corresponding to a part of a TF set including a plurality of TFs available for an uplink service are received. One of the first TFs is determined as a reference TF for a second TF other than the first TFs in the TF set. Then, a second gain factor for the second TF is calculated using the first gain factor for the determined reference TF. The second gain factor is used for transmitting or receiving uplink data.

A method for allocating resources in a mobile communication system is provided. The resource allocation method includes determining whether a transmission time of response information indicating presence/absence of an error in received data overlaps a transmission time of channel state information; and when the transmission times overlap each other, allocating, to the response information, a resource block for the channel state information, cyclic shift values in a frequency domain, and orthogonal sequences having orthogonality in a time domain.
摘要:
A method for allocating resources for transmission of an uplink Acknowledgement (ACK)/Negative ACK (NACK) used for indicating success/failure in reception of downlink transmission data by a base station in a mobile communication system. The resource allocation method includes determining a mapping rule between control channel elements constituting a downlink control channel and resources for ACK/NACK transmission; transmitting, to at least one User Equipment (UE), control information used for indicating to acquire the determined mapping rule and resources for ACK/NACK transmission allocated using the mapping rule; transmitting a downlink data channel though a predetermined scheduling operation; and transmitting the downlink control channel to the UE.

A method is provided for allocating resources of a control channel in a mobile communication system using Orthogonal Frequency Division Multiplexing (OFDM). The method includes, when a time index and a frequency index of available Resource Elements (REs) are defined as l and k, respectively, dividing the available REs in a two-dimensional structure of (k, l); and time-first-allocating each RE to a plurality of RE groups while increasing the time index l for each frequency index k from an initial value up to a predetermined range.
摘要:
An apparatus and method are provided for setting gain factors for dedicated physical channels in a mobile communication system. The UE receives configuration information indicating uplink dedicated physical channel configuration. The UE sets a gain factor of a dedicated physical control channel (DPCCH) to 1 in the case that no DPDCH is configured. The UE calculates a gain factor of a enhanced dedicated physical control channel (E-DPCCH) using the gain factor of the DPCCH.
