Abstract: It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.

Abstract: Methods and apparatus for limiting communication capabilities in mobile communication devices are disclosed. In one illustrative example, a predetermined condition such as an unsatisfactory temperature or a low battery voltage is detected at the mobile communication device. At this time, a communication request for communicating information through a wireless communication network is received through a user interface. If the communication request is for a non-emergency communication, the non-emergency communication is inhibited during the existence of the predetermined condition. If the communication request is for an emergency communication, however, the emergency communication is allowed despite the existence of the predetermined condition. The emergency communication may be allowed at a reduced transmit power and/or using limited coding/modulation methods. The emergency communication may be a “911” voice call or an emergency message. The reception of communications may still be allowed but inhibited upon more adverse conditions.

Abstract: The application relates to wireless networks and more particularly to a method of reducing factory test time of receiver sensitivity in a Code Division Multiple Access (CDMA) wireless device. Under TIA/EIA/-98E, the radio frequency (RF) sensitivity of a CDMA wireless receiver is the minimum received power, measured at the mobile station antenna connector, at which the frame error rate (FER) does not exceed 0.5% with 95% confidence. In order to reduce the test time of FER test method, the relation between correlated energy (or Ec/Io) and FER is determined using simulated traffic and the correlated energy (or Ec/Io) measurement is then used as the test parameter on like models to achieve the same or superior test confidence with significantly reduced test time.

Abstract: Methods and apparatus for facilitating concurrent Push-to-talk over Cellular (PoC) group communication sessions for a mobile station (102) are disclosed. A first PoC communication session (550) for a first user group (504) is maintained while a second PoC communication session (552) for a second user group (506) is concurrently maintained, where the second user group (506) has at least one common member (516) with the first user group (504). The second user group (506) may have at least one member (518, 520) which is not included in the first user group (504). Through a user interface, a PoC user may select between the first and the second user groups (504 and 506) for communication or combine the communications. In an alternative embodiment, all of the members (518, 520, 522) of a second user group (604) may be included in a first user group (602). In a specific approach, encrypted data packets of a PoC communication sub-session are communicated during a PoC communication session. If a key for the encrypted data packets is known for the mobile station (102), the encrypted data packets are decrypted to facilitate the PoC communication sub-session involving the mobile station (102); otherwise the encrypted data packets are discarded.
