China on Wednesday lauded Taiwan’s launch of a 3G mobile network using Chinese TD-SCDMA technology as a successful display of how they can work together on technical standards.

Executives and officials from both places on Wednesday concluded a technical standards forum in Taipei where they discussed TD-SCDMA (Time-Division Synchronous Code Division Multiple Access), as well as the creation of standards for LCD screens, LED technology, audio/visual devices, Internet TV, green technologies and more. continue reading…

China issued 3G licenses in January, 2009, to three telcos, China Mobile,China Telecom and China Unicom. The Chinese Ministry of Industry and Information Technology said the country would invest CNY400 billion (US$59 billion) in the next three years. China Mobile received a licence forTD-SCDMA, the domestically-developed 3G standard, China Telecom will use the US-developed CDMA2000 and China Unicom will use WCDMA(GSM). continue reading…

Air interface framing is illustrated as in figure below. A super frame is made up of 4096 radio frames. Each radio frame is made up of 15 timeslots. A timeslot can be allocated to either UL (uplink) and DL (downlink) transmission.

Within each timeslot several Resource Units (RUs) (sometime termed “codes” or “bursts”) can be supported. An RU is defined as a single code within a single timeslot. As defined in 3GPP TD-CDMA downlink supports two spreading factor, SF1 and SF16. IPWireless implements both SF1 and SF16 for the downlink.
