Problems solved by technology

In the mixed time slot of scheduled E-DCH and non-scheduled E-DCH / DPCH, if the RNC and Node B have inconsistent understanding of the maximum RTWP allowed for this time slot, it will cause the RNC to perform non-scheduled E-DCH in the mixed time slot Contradictions occur between the DPCH radio resource management algorithm decision and the Node B scheduling E-DCH power grant, resulting in the failure of each other's algorithms

Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] refer to figure 1 , illustrating a method for power granting a scheduling enhanced dedicated channel according to an embodiment of the present invention. Among them, the method is used in the TD-SCDMA system supporting HSUPA. Such as figure 1 As shown, the method includes the following steps: S102, the radio network controller sends a physical shared channel reconfiguration message to the Node B, wherein the physical shared channel reconfiguration message adds the maximum received total broadband power that can be used by the scheduling enhanced dedicated channel information; and S104, the Node B grants to the scheduling user a power not greater than the maximum received total broadband power that can be used by the scheduling enhanced dedicated channel in one time slot.

[0018] refer to figure 2 , illustrating a meth...

Abstract

The invention discloses a method for obtaining available power of a dispatching enhancement private channel by a node B, which comprises the following steps: a wireless network controller transmits reconfiguration information of a physical shared channel to the node B; wherein, the reconfiguration information of the physical shared channel carries out information of the maximum RTWP which can be used by the dispatching enhancement private channel; the node B obtains the maximum RTWP which can be used by the dispatching enhancement private channel from the reconfiguration information of the physical shared channel. The method can solve the problems that the dispatching enhancement private channel and the non dispatching enhancement private channel coexist in the same time slot so that the node B can not obtain the available power of the dispatching enhancement private channel.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for a node B to obtain the available power of a scheduling enhanced dedicated channel. Background technique [0002] In a Time Division-Sychronous Code Division Multiple Access (TD-SCDMA) system supporting High Speed ​​Uplink Packet Access (HSUPA for short), an Enhanced Dedicated Channel (Enhanced Dedicated Channel, The uplink received total wide band power (Received total wide band power, RTWP) used by E-DCH for short is controlled by Node B, and the RTWP used by non-scheduled E-DCH and Dedicated Physical Channel (DPCH for short) It is controlled by a radio network controller (Radio Network Controller, RNC for short). In the mixed time slot of scheduled E-DCH and non-scheduled E-DCH / DPCH, if the RNC and Node B have inconsistent understanding of the maximum RTWP allowed for this time slot, it will cause the RNC to perform non-scheduled E-DCH in the mixe...
