Pick to the present network TD-SCDMA system data business model HSDPA time slot configuration is 2:4
R4 carrier also time slot configuration
since the R4 carrier are DCH channel
main bearing CS business
the business has downlink symmetrical characteristic
therefore
for R4 carrier downlink will have 2 slot idle
leading to channel resources a waste of.TD-SCDMA R4 and HSDPA carrier technology to solve the HSDPA carrier resource scarcity and other R4 carrier code channel have any problems
can improve the TD-SCDMA system resource utilization rate.This paper discusses the principle of the technology
introduced the network test
analysis of the introduction effect and the possible risks.TD-SCDMA network for subsequent carrier time slot allocation principle provides good planning advice.
