Method, system and device for determining power offset parameter

Abstract

A method for determining a Power Offset (PO) is disclosed. The method includes: configuring a PO corresponding to an information element for a NodeB and a UE; the UE and the NodeB determines a PO for a currently transmitted MAC-e PDU according to an information element constituting the MAC-e PDU, the PO configured and a predefined PO determining rule. A system, a UE and a NodeB for determining PO are also disclosed. According to the present invention, when MAC-d flows carrying a service to be transmitted at the UE are not changed, the PO corresponding to any MAC-e PDU which is transmitted at any time and uses the same type of resource as the above MAC-e PDU will not change. Thus, the NodeB needs not to decode a received MAC-e PDU to determine the PO corresponding to the MAC-e PDU, which improves power control performance of the NodeB.

Description

technical field

[0001] The present invention relates to High Speed ​​Uplink Packet Access (HSUPA: High Speed ​​Uplink Packet Access) technology, in particular to a method, system and device for determining power offset parameters. Background technique

[0002] In order to meet the development needs of high-speed data services in mobile networks, Frequency Division Duplex (FDD: Frequency Division Duplex) and Time Division Duplex (Time Division Duplex) were successively introduced in Version 6 and Version 7 of the 3rd Generation Partnership Project (3GPP). Enhanced Uplink (EnhancedUplink) technology, also known as HSUPA technology.

[0003] Among them, in the TDD HSUPA technology, an enhanced uplink physical channel (E-PUCH: Enhanced Physical Uplink Control Channel) and an uplink enhanced dedicated channel uplink control channel (E-UCCH: E-DCH Uplink Control Channel) are introduced, where E -PUCH is used to transmit uplink Enhanced Dedicated Channel (E-DCH: Enhanced Dedicated...
