Problems solved by technology

However, for the same terminal, the MAC-d flow mapped to the highest priority logical channel in the MAC-e PDU transmitted at different times may change. Correspondingly, the corresponding Δ harq will keep changing, and because the base station (Node B) is the receiving end of the MAC-ePDU, it cannot accurately know Δ harq Therefore, Node B cannot base on the accurate Δ harq Calculate beta e , which in turn affects the performance of power control, and also causes a series of problems related to power control and other scheduling

Embodiment Construction

[0059] The embodiment of the present invention mainly includes: configuring the PO corresponding to the constituent cells of the MAC-e PDU for the base station and the terminal; after that, the terminal and the base station configure the PO according to the constituent cells of the currently transmitted MAC-e PDU, the configured PO, and the predefined PO A rule is determined to determine the PO corresponding to the currently transmitted MAC-e PDU.

[0060] Considering that in the high-speed uplink enhancement technology, the terminal will report scheduling information (SI: Scheduling Information) in order to request the base station to schedule resources or assist the base station in resource scheduling. In the embodiment of the present invention, the constituent information elements of the above-mentioned currently transmitted MAC-e PDU can be in various forms, for example, the constituent information elements of the currently transmitted MAC-e PDU only include scheduling info...

Abstract

The invention discloses a device for determining a power offset parameter. The method comprises the following steps: a media access control E-DCH protocol data unit MAC-e PDU is configured for a base station and a terminal to form a power offset parameter PO corresponding to a cell; and the PO corresponding to the currently transmitted MAC-e PDU is determined by the terminal and the base station according to the cell of the currently transmitted MAC-e PDU, the configured PO and the predefined PO determination rule. The invention also discloses a system, a terminal and a base station for determining the power offset parameter. The power ratio of the fuzzy target signal and the interference noise can be avoided to be calculated through the base station to further enhance the accuracy of the high-power control command.

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...
