ML, IQ linked the specs to 25.304 over at RB. You know where it is. Note that IQ and others are trying to corroborate IDCC's claims in the 1999 annual report which represent indirect feedback from 3GPP's Release 99. Given how WCDMA will be rolled out in different parts of the world over the next decade, the reasonable expectation is that 3GPP will continuously tweak the WCDMA specs every year to reflect progress in other parts of technology that enable certain solutions that were not previously practical. Anyway, that discussion revolves around these IDCC claims. The question is whether seamless handover is being designed in for Release 2000. Note that IDCC has not yet claimed that it is part of the standard. You will also find the minutes of the last meeting held in France about 2 weeks ago. 6) Global Pilot Channel -- This feature is a key element of virtually every CDMA system. It is a reference signal transmitted by the base station that allows reliable and robust communications by all mobile users. Now a part of the new 3G standard, we originally used this technique as part of our B-CDMA air interface. 9) Power Ramp-up and Call Establishment -- In CDMA systems, it is critical that no one user transmit more power than is required to establish and maintain a call to avoid interference with other callers. We invented this ramp-up scheme to allow a user to enter a system at a low power level and increase it gradually until the call is recognized by the base station. We developed and used this technique in our B-CDMA air interface, and a modified version of it is part of the 3G standard. 10) Seamless Hand-Over -- Our method of handing over CDMA calls between cells requires minimum system overhead and maximizes CDMA system capacity. This increases the coverage area, accommodates more users and saves battery life. Message 14053468 Draft Report of the 14th TSG-RAN WG2 meeting (Paris, France, 3 - 7 July 2000) Document for Comments Source: 3GPP support team .........Experts from WG4 and SMG2 took part in the meeting on Monday 3 and Tuesday 4 July to resolve issues on various types of handovers and cell selection/re-selection. The immediate cell evaluation procedure came under renewed scrutiny (more study needed). On inter-RAT reselection it was understood that consistent behavour in both GSM-UMTS and UMTS-GSM directions was possible. Since SMG2 had already decided that it was not feasible to align all GSM and UMTS procedures, a solution needs to be found to minimise the number of reselections to another technology...... ragingbull.altavista.com
