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

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...
