Embodiment Construction

[0057] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0058] The main idea of ​​the multi-carrier HSUPA power limited indication scheme of the present invention is: the terminal carries the information of whether the network authorized power meets its own requirements to the network side (NodeB) through SI, so that when the network authorized power cannot meet the terminal's own requirements, it will happen When the power is limited, the NodeB will give more authorized power to the terminal.

[0059] Such as figure 1 Shown is the flow of the indication method of multi-carrier HSUPA power limitation in the present invention, including:

[0060] Step 101, the terminal determines whether the authorized power of the network meets its own requirements;

[0061] When the terminal determines that the sum of the E-PUCH power calculated by each carrier based on the authorized ...

Abstract

The invention discloses an instruction method of multicarrier high speed uplink packet access (HSUPA) power constraint. The method comprises the following steps that: a terminal determines whether a network authorization power satisfies a requirement of the terminal; the terminal carries the information that whether the network authorization power satisfies the requirement of the terminal in scheduling information (SI) and sends to a node B. The invention also discloses the terminal and an instruction system of the multicarrier HSUPA power constraint. By using the method, the terminal and the system of the invention, an error probability of receiving E-DCH uplink control channel (E-UCCH) by a network side caused by the power constraint can not be increased, and the probability that enhanced uplink physical channel (E-PUCH) can not be received correctly by the user can not be increased.

Description

technical field [0001] The present invention relates to Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division Synchronous Code Division Multiple Access) technology, in particular to a multi-carrier high speed uplink packet access (HSUPA, high speed uplink packet access) power limited Methods, systems and terminals are indicated. Background technique [0002] In the HSUPA system, the transmit power of the enhanced uplink physical channel (E-PUCH, Enhanced Uplink Physical Channel) at the user terminal (UE, User Equipment) side is calculated according to the following formula: [0003] (1)P E-PUCH =P e-base +L+β e . [0004] Among them, P E-PUCH is the transmit power of E-PUCH; P e-base A closed-loop quantity maintained for UE and Node B (NodeB), which will increase or decrease a certain value Δ every time a transmission power control (TPC, Transmission Power Control) command is received e-base ,Δ e-base The size of the value is configured by ...
