Embodiment Construction

[0024] figure 1 Is the overall flow chart of the present invention. Such as figure 1 Shown, the present invention comprises the following steps:

[0025] Step 101, the present invention first removes the overloaded transmission format combination and its session derivative set according to the current requirements of the physical channel carrying capacity after deducting the influence of the compressed mode transmission interval, and obtains the TFCS subset;

[0026] Step 102, then check whether the TFCS subset contains the minimum set and its session class derivative set;

[0027] Step 103, if the minimum set and its session class derivative set are not included, return failure;

[0028] Step 104, otherwise check whether there is more than one non-conversational service in the concurrent service except signaling;

[0029] Step 105, if there is more than one, use the minimum set and its session class derivative set as a new TFCS subset;

[0030] Step 106, finally output t...

Abstract

This invention discloses one WCDMA mobile communicating system transfer grid combination filter method, which comprises the following steps: filtering super load transmission grade and its dialogue derivative set to get one transmission set; testing the said transmission grid set whether or not comprising one transmission set and its dialogue set; if not comprising transmission form set minimum set and its derivative set and then reporting filter failure and close; otherwise, there is only one non-dialogue besides signals and using the transmission form set as final filter result.

Description

technical field [0001] The present invention relates to a high-level scheduling transport format combination set (TransportFormat Combination Set, TFCS) screening method of a wireless cellular communication system, in particular to a wideband code division multiple access (WCDMA) mobile communication system compression mode high-level scheduling transport format combination set screening method . Background technique [0002] Adopting the compressed mode in the WCDMA system means that in the process of sending and receiving, some time slots will not be used for data transmission, but are used for measurements on other frequencies. The protocol stipulates that there are three methods for generating compressed mode frames: 1) halving the spreading factor (SF / 2); 2) Higher Layer Scheduling; 3) Puncturing. The halving of the spreading factor is to send the data bits to be transmitted in a transmission time interval (TransmissionTime Interval, TTI) in the time slot except the tr...
