Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

Abstract: The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and/or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values are received. Each list of processed attribute values includes attribute values considered acceptable to the second entity. The layers and protocols in the first entity are then configured in accordance with the received list of processed attributes and their associated processed attribute values. Other features related to configurable layers and protocols are also provided.

Abstract: Techniques for conveying reports for SMS messages in wireless communication networks that utilize CDMA air interface (e.g., GSM1x and CDMA networks). Two new messages SMS Deliver Report Message and SMS Submit Report Message are defined for CDMA SMS. These report messages may be used to more fully convey the information in the SMS-Deliver-Report TPDU and SMS-Submit-Report TPDU defined in GSM SMS. A new Report_Req field is also provided in the Reply Option subparameter of the SMS Deliver Message and SMS Submit Message defined in CDMA SMS. This new field may be used to request a report for an SMS message to be sent by the message's recipient. Each report message may include (1) a first value indicative of whether the SMS message was received correctly or in error, (2) a second value indicative of a type of error, if any, encountered for the SMS message, and (3) user data.

Abstract: In an exemplary application, an apparatus according to a disclosed embodiment receives a radio frequency signal and outputs an intermediate frequency signal. Rejection of image components in the intermediate frequency signal is obtained without the need to preprocess the radio frequency signal with an image reject filter. Such an apparatus may also exhibit an image rejection performance that is robust to frequency deviation of a local oscillator.

Abstract: Methods and apparatus to optimize delivery of multicast content using probabilistic feedback. A method is provided for transmitting data from a server to a plurality of receiving terminals. The method includes transmitting the data from the server to the plurality of receiving terminals, and generating a random response value at each receiving terminal. The method also includes comparing the response value to an acknowledgement value at each receiving terminal, and transmitting an acknowledgment signal to the server from selected receiving terminals. The selected receiving terminals are a portion of the plurality of receiving terminals where the response value has a selected relationship to the acknowledgement value.
