    • A method and a device for reconfiguration in a wireless system utilizing flexible layer one (FLO). In proposed solution one TFC (Transport Format Combination) is selected and reserved (504) exclusively for signalling use. The TFC may contain only one active transport channel and always utilize the same CRC and transport block size in order to unambiguously define the proper settings for signalling. Considering uplink transmission in a wireless system and special case of TFCI (Transport Format Combination Identifier) size change due to the TFCS (Transport Format Combination Set) reconfiguration that also generates a need to switch to a new dedicated basic physical subchannel (DBPSCH); whenever the network notices that the mobile station does not switch to the new DBPSCH (518), it concludes that the TFCS reconfiguration message sent was lost and stays with the existing configuration (520). Otherwise the new configuration is taken into use (514).
    • 一种利用柔性层一(FLO)的无线系统中的重新配置的方法和装置。 在提出的解决方案中,专门用于信令使用的TFC(传输格式组合)被选择和保留(504)。 TFC可以仅包含一个活动传输信道,并且始终使用相同的CRC和传输块大小,以明确地定义用于信令的适当设置。 考虑到无线系统中的上行链路传输和由于TFCS(传输格式组合集)重配置而导致的TFCI(传输格式组合标识符)大小变化的特殊情况,TFCS(传输格式组合集)重新配置也产生切换到新的专用基本物理子信道(DBPSCH)的需要; 每当网络注意到移动台不切换到新的DBPSCH(518)时,它得出结论,发送的TFCS重新配置消息已经丢失并且保持现有配置(520)。 否则将使用新配置(514)。

    • A data transmission method and system for circuit switched and other services that can be employed in TDMA-based systems, and that supports the use of one or several types of modulation (e.g., 8-PSK modulation), in addition to a “normal” modulation (e.g., GMSK modulation) on a radio interface. An additional modulation/channel coding (e.g., one based on 8-PSK) may be used in the downlink transmission, while the normal modulation/channel coding (e.g., one based on GMSK) may be used in the uplink transmissions, under a variety of different conditions. A first condition arises where the radio conditions allow the use of the additional modulation in both directions, but the mobile station transmitter does not support it. A second condition arises where the radio conditions allow the use of the additional modulation in both directions, and the mobile station supports it, but the user requests a downlink-biased or uplink-biased data transmission service. A third condition arises where the mobile station supports the use of the additional modulation in both directions, but the uplink (or downlink) radio conditions do not permit the use of the additional modulation (e.g., because of link budget limitations.) Also, a lower data rate may be desired on the uplink in order to reduce the power consumption of the mobile station, and/or in the downlink direction to avoid unnecessary interference. This is especially true in the case that one direction or the other has less data to transmit, and the high speed data transmission mode is not required (even if supported).
    • 一种用于电路交换和其他服务的数据传输方法和系统,其可以在基于TDMA的系统中使用,并且除了“正常”之外还支持使用一种或几种类型的调制(例如,8-PSK调制) 在无线电接口上进行调制(例如,GMSK调制)。 在下行链路传输中可以使用附加的调制/信道编码(例如,基于8-PSK的一个)编码(例如,基于GMSK的正常调制/信道编码)可以在上行链路传输中使用 的不同条件。 出现无线电条件允许在两个方向上使用附加调制的第一个条件,但移动台发射机不支持它。 出现第二个条件,其中无线电条件允许在两个方向上使用附加调制,并且移动台支持它,但是用户请求下行链路偏置或上行链路偏置的数据传输服务。 第三个条件出现在移动台支持在两个方向上使用附加调制,但是上行链路(或下行链路)无线电条件不允许使用附加调制(例如,由于链路预算限制)。另外,一个 为了降低移动台的功率消耗和/或在下行链路方向,为了避免不必要的干扰,在上行链路上可能希望较低的数据速率。 在一个方向或另一方向具有较少的传输数据的情况下尤其如此,并且不需要高速数据传输模式(即使被支持)。
