Abstract: A complex spreading and/or scrambling code sequence ("scrambling code sequence") generation system uses a first complex code sequence having at least two components and a second complex code sequence having at least two components. The components of the first complex code sequence are respectively mixed with the corresponding components of the second complex code sequence to generate the complex scrambling code sequence. In doing so, an offset between the components of the complex scrambling code sequence is achieved for the same and/or different users. For example, the complex spreading code sequence generation system can use a long code generator which produces a long code sequence produced from the inner product of a code vector and a user mask. The long code sequence is provided to an I path and a Q path. To produce a complex long code sequence, the long code sequence on the Q path is delayed to produce a second long code sequence on the Q path or a Q component of the complex long code sequence. On the I path, the I long code sequence or the I component of the complex long code sequence is multiplied with an I component of a short code sequence to produce the I component of the complex scrambling code sequence. On the Q path, the Q long code sequence is multiplied with a Q component of the short code sequence to produce the Q component of the complex scrambling code sequence. As such, the offset between the components of the complex scrambling code sequence between different and/or the same user is at least the period of the short code. The complex scrambling code sequence can be used for spreading, scrambling, de-spreading or de-scrambling an information signal.

Abstract: In a wireless communications system, a base station transmits power control signals (e.g., the power control bits of a power control sub-channel) to a mobile using a forward-link channel that is decoupled from all other signals transmitted from that base station to that mobile. For example, the decoupled forward-link channel may be a common power control channel. The mobile then uses the power control signals received in the decoupled forward-link channel to control its power level for transmitting one or more reverse-link channels to the base station. The ability of base stations to use decoupled forward-link channels in order to transmit their power control signals to a mobile enables a mobile to operate with different active sets for the forward and reverse links. This enables forward-link data traffic to be implemented using a simplex mode, even when the mobile is operating in soft handoff in the reverse link. This in turn greatly reduces the reactivation time involved in transitioning a mobile from the suspended state to the active state, which is particularly desirable for bursty (i.e., intermittent) packet data flow, as opposed to continuous circuit-oriented voice messaging.

Abstract: Disclosed is a common transmitter architecture having incorporated both open loop transmit diversity schemes using a plurality of binary switches. Employment of binary switches allows for the sharing of certain components whether the transmitter is utilizing a orthogonal transmit diversity (OTD) scheme or a space time spreading (STS) scheme. Accordingly, the number of components in the transmitter is minimized and the complexity of the transmitter is simple enough to be implemented into a single application specific integrated chip.
