Embodiment Construction

[0030] Functional Overview

[0031] Embodiments of the present invention provide a power state determination scheme, which can be used but not limited to Wideband Code Division Multiple Access (WCDMA for short), for example, can also be applied to time division synchronization code For a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, the embodiment of the present invention takes the WCDMA system as an example for illustration. The processing principle of this scheme is: , to estimate the transmit power of other unused TFCs (Transport Format Combinations) in the TFCS (Transport Format Combination Set). The detailed processing of this scheme is as follows: according to the information of the first transmitting power and TFC of each uploading time slot in the frame, determine the second transmitting power required to use TFC in each uploading time slot; The maximum transmit power of the devices is compared one by one to determine the number of times ...

Abstract

The invention discloses a method and a device for determining power state. The method comprises the following steps: determining a second transmission power desired for transmission format combination used in each uploading time slot according to information of transmission format combination not used in the set of the first emission power and the transmission format combination of each uploadingtime slot in a frame; comparing the second transmission power with the maximum transmission power of user equipment one by one to determine the times that of the second transmission power exceed the maximum power; and according to the times, determining the power state of the transmission format combination. The invention solves the problem of transfer among three power states of the transmissionformat combination (TFC_, and ensures the real-time monitoring of the power state of each TFC so as to avoid using the TFC at the forbidden state and ensure the QoS of the service.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for determining a power state. Background technique [0002] In the data link layer, the media access control (Media Access Control, referred to as MAC) layer provides a logical channel (Logical Channel, referred to as LC) for the radio link control (Radio Link Control, referred to as RLC) to carry the RLC data, and the physical layer provides a transport channel (Transport Channel, referred to as TrCH) for the MAC layer to carry the data of the MAC layer. Each transport channel TrCH can only transmit data in certain fixed formats, and these fixed formats are called Transport Format Set (TransportFormat Set, referred to as TFS), all transport channels TrCH that are multiplexed into a code composite transport channel (CodeComposite Transport Channel, referred to as CCTrCH) are configured with a Transport Format Combinations Set (Transport Format CombinationsS...
