A method for transmitting an enhanced Random Access CHannel (RACH) in a User Equipment (UE) in a mobile communication system is provided, in which the UE transmits an uplink preamble to a Node B and upon receipt of an ACKnowledgment (ACK) for the uplink preamble, transmits an Enhanced Uplink Dedicated CHannel (E-DCH) and a Dedicated Physical Control CHannel (DPCCH) to the Node B. The transmission of the DPCCH starts before the transmission of the E-DCH.

A method for transmitting an enhanced Random Access CHannel (RACH) in a User Equipment (UE) in a mobile communication system is provided, in which the UE transmits an uplink preamble to a Node B and upon receipt of an ACKnowledgment (ACK) for the uplink preamble, transmits an Enhanced Uplink Dedicated CHannel (E-DCH) and a Dedicated Physical Control CHannel (DPCCH) to the Node B. The transmission of the DPCCH starts before the transmission of the E-DCH.

Methods and apparatus are provided for communication between a User Equipment (UE) and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including scheduling information having information representing an amount of packet data to be transmitted. The MAC-PDU including the scheduling information is transmitted to the Node B. The information representing the amount of packet data exists per priority queue.

A method and apparatus are provided for transmitting user equipment (UE) status information in communication with one serving Node B and at least one non-serving Node B in a mobile communication system. The method and apparatus comprise generating transport channel data including UE status information; transmitting the transport channel data to the serving Node B and the at least one non-serving Node B, receiving a response signal for the transport channel data from the serving Node B, and retransmitting the transport channel data if the response signal received from the serving Node B is a non-acknowledge (NACK) signal, and ending the retransmission of the transport channel data if the response signal received from the serving Node B is an acknowledge (ACK) signal.

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.

A system and method are provided for setting gain factors for dedicated physical channels in a mobile communication system supporting E-DCH service. If the E-DCH is established without the legacy DCH, the UE sets a gain factor for a DPCCH related to the DCH to a predetermined constant and calculates gain factors for dedicated physical channels related to the E-DCH using the gain factor of the DPCCH. In another embodiment of the present invention, if the E-DCH is established without the legacy DCH, the RNC sets a gain factor for a DPCCH related to a virtual DCH to a predetermined constant and sends channel configuration information including the gain factor to the UE.

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.
摘要:
A method and apparatus for scheduling uplink data transmission for a UE in a mobile communication system supporting an uplink packet data service are provided. A serving Node B and at least one non-serving Node B are included in an active set of a UE located in a soft handover region. The UE receives a dedicated scheduling grant from the serving Node B by dedicated scheduling and a common scheduling grant from the at least one non-serving Node B, controls an uplink data rate not to exceed a previous uplink data rate during a predetermined validity duration, if the common scheduling grant indicates a rate-down, and transmits uplink data at the controlled uplink data rate.

Disclosed are a method and an apparatus for determining rate matching parameters for transport channels in mobile telecommunication system. The apparatus and method include determining first physical channel bit sizes usable in transmitting at least one first transport channel not supporting hybrid automatic repeat request (HARQ) and at least one second transport channel supporting the hybrid automatic repeat request, determining if there is at least one second physical channel bit size in the first physical channel bit sizes, the second physical channel bit size allowing transmission for a size of coded bits corresponding to the first transport channel and a size of coded bits corresponding to the second transport channel based on rate matching and puncturing, reducing the size of the coded bits corresponding to the second transport channel when the second physical channel bit size is not included in the first physical channel bit sizes, returning to the step of determining if there is at least one second physical channel bit size after the size of the coded bits corresponding to the second transport channel is reduced, and when there is at least one second physical channel bit size, selecting one second physical channel size based on at least one second physical channel bit size as a rate matching parameter for the first transport channel and the second transport channel.
摘要:
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.
