Abstract: A received power of a code division multiple access (CDMA) signal is determined. Samples of a spectrum associated with the received CDMA signal are taken as received samples, which are then correlated with a code of the CDMA signal. For correlated samples below a first threshold, those correlated samples are processed by being made to be zero. For samples between the first threshold and a second threshold, those correlated samples are processed by rescaling. The correlated samples above the second threshold are passed unchanged. The received power level of the received CDMA signal is determined using the correlated samples after the processing.

Abstract: A wireless transmit/receive unit (WTRU) includes a control plane (C-plane) packet data convergence protocol (C-PDCP) layer which performs ciphering of a signalling message. The C-PDCP layer is activated upon power up of the WTRU and initial security parameters are located to the C-PDCP layer. An initial connection signalling message and a user identity are ciphering using the initial security parameters even before the WTRU is authenticated. The initial security parameters including a ciphering key (CK) may be generated from system information broadcast from the network. The CK may be a public key for asymmetric encryption, and may be selected from a public key set broadcast by or derived from the network system information. An index of the selected public key may be separated from a public key set broadcast by or derived from the network system information. An index of the selected public key may be separately encoded. Alternatively, the index may be communicated by using a Diffie-Hellman key exchange method. 4I=5 s qj- W- 0n m ra co r :se Cm Le LU LL cC o 080 CJJ 2e0 uJ~tu U-0I C o o *o LL r I a C, 53c 0 cC5

In one embodiment, the MTP includes: a device manufacturer- trusted subsystem (TSS-DM) configured to store and provide credentials related to a manufacturer of the MTP; a mobile network operator - trusted subsystem (MNO-TSS) configured to store and provide credentials related to a mobile network operator (MNO); and a device user/owner - trusted subsystem (TSS-DO/TSS-U) configured to store and provide credentials related to user of the MTP. The TSS-MNO includes a vSIM core services unit, configured to store, provide and process credential information relating to the MNO. The TSS-DO/TSS-U includes a vSIM management unit, configured to store, provide and process credential information relating to the user/owner of the MTP.

Abstract: Una unidad transmisora/receptora inalámbrica (WTRU) incluye una capa de protocolo de convergencia de datos de paquete (C-PDCP) de plano de control (plano C) la cual realiza cifrado de un mensaje de señalización. Se activa la capa C-PDCP ante el encendido de la WTRU y se cargan los parámetros de seguridad iniciales a la capa CPDCP. Un mensaje de señalización de conexión inicial y una identidad de usuario se cifran utilizando los parámetros de seguridad iniciales incluso antes de que se autentifique la WTRU. Los parámetros de seguridad iniciales incluyen una clave de cifrado (CK) se pueden generar a partir de la información de sistema difundida desde la red. La CK puede ser una clave pública para codificación asimétrica y se puede seleccionar a partir de un conjunto de claves públicas difundidas o derivadas de información de sistema de red. Se puede codificar por separado un índice de la clave pública seleccionada. De manera alternativa, el índice se puede comunicar utilizando un método de intercambio de clave Diffie-Hellman.

Abstract: The system and method of the present invention establishes a communication link between a user equipment (UE) and a base station in a communication system having a plurality of base stations which each transmit a common primary synchronization code (PSC) in a primary synchronization channel in conjunction with a base station specific secondary synchronization code (SSC) within a system frame, which receives with the UE an input signal including the PSC and SSC from at least one of the base stations. The UE analyzes the input signal to detect any received PSCs within a selected time period which has duration corresponding to the length of a system frame and determining a relative location of a strongest PSC within the selected time period. The input signal is then processed to remove the PSC from at least the determined PSC location. A secondary synchronization code (SSC) is then detected for the determined location from the processed signal. The communication link is then established using the detected SSCs.
