    • A method and apparatus for estimating channelization codes in a wireless transmit/receive unit (WTRU) using blind code detection (BCD). A WTRU receives communication bursts and detects a midamble in the received burst. A candidate code list is generated in accordance with the detected midamble. The candidate code list includes channelization codes intended for both the intended WTRU and other WTRUs. Active channelization codes among the codes in the candidate list are identified, and the identified codes are forwarded to a multi-user detector (MUD). Since the orthogonal variable spreading factor code maintains the orthogonality between codes of different SF, SFs of other WTRUs follow the SF of the intended WTRU. Moreover, since the data for other WTRUs is not used in symbol processing after MUD, the performance of MUD for the intended WTRU is preserved with the SF ambiguity of other WTRUs.
    • 一种使用盲码检测(BCD)估计无线发射/接收单元(WTRU)中的信道化码的方法和装置。 WTRU接收通信突发并检测接收到的突发中的中间码。 根据检测到的中间码产生候选码列表。 候选代码列表包括旨在用于预期的WTRU和其他WTRU的信道化代码。 识别候选列表中的代码之间的主动信道化代码,并将所识别的代码转发到多用户检测器(MUD)。 由于正交可变扩频因子码维持不同SF的码之间的正交性,其他WTRU的SF遵循预期的WTRU的SF。 此外,由于在MUD之后的其他WTRU的数据不用于符号处理,所以对于预定的WTRU的MUD的性能由其他WTRU的SF模糊性来保留。

    • A transmitting station performs closed loop power control prior to a transmission pause. A closed loop transmission power level prior to the pause is determined. A reference signal is received and a received power level of the reference signal prior to and during the transmission pause is determined. The measured reference signal received power levels are compared to a transmit power level of the reference signals to produce a pathloss estimate of the reference signal prior to and during the transmission pause. A new transmit power level is determined by adjusting the closed loop transmission power level by a change between the prior to and during pathloss estimates. A transmission power level of the transmitting station is set to the determined new transmit power level. A communication is transmitted at the set transmission power level.
