Problems solved by technology

[0002] At present, how to effectively reduce the power loss of the base station has always been a concern of equipment manufacturers and operators. Therefore, the 3GPP protocol provides the downlink CPC (continuous packet connectivity) technology in the R7 version, which saves energy through downlink discontinuous transmission. The transmit power on the base station side improves the system capacity. However, the CPC function defined by the protocol can only be used in pure HSPA (High-Speed ​​Packet Access, high-speed data packet access / access technology), that is, the downlink uses F- DPCH (Fractional Dedicated Physical Channel, some dedicated physical channels), this function requires terminal support of R7 and above protocol versions
At present, there are many ordinary R99, R5 and R6 terminals in the commercial network. These terminals do not support the CPC function. Therefore, based on the current situation, there is no similar technology to save the power of the base station for these terminals, and only the continuous transmission mode can be used.

Abstract

A method and a device for transmitting a downlink dedicated physical channel (DPCH). The method comprises: determining whether a preset condition is met; if yes, performing processing of discontinuously sending a pilot of a pilot domain of a DPCH; and otherwise, continuously sending the pilot of the pilot domain of the DPCH.

Description

technical field [0001] The present invention relates to the field of UMTS (Universal Mobile Telecommunications System, universal mobile communication system), in particular to a method and device for transmitting a downlink dedicated physical channel (DPCH). Background technique [0002] At present, how to effectively reduce the power loss of the base station has always been a concern of equipment manufacturers and operators. Therefore, the 3GPP protocol provides the downlink CPC (continuous packet connectivity) technology in the R7 version, which saves energy through downlink discontinuous transmission.
