    Abstract: Techniques for encoding and decoding data are described. In an aspect, multiple code rates for a forward error correction (FEC) code may be supported, and a suitable code rate may be selected based on packet size. A transmitter may obtain at least one threshold to use for code rate selection, determine a packet size to use for data transmission, and select a code rate from among the multiple code rates based on the packet size and the at least one threshold. In another aspect, multiple FEC codes of different types (e.g., Turbo, LDPC, and convolutional codes) may be supported, and a suitable FEC code may be selected based on packet size. The transmitter may obtain at least one threshold to use for FEC code selection and may select an FEC code from among the multiple FEC codes based on the packet size and the at least one threshold.

    Abstract: Systems and methodologies are described that facilitate silence interval specification and utilization in wireless communications. In particular, a silence interval can be defined such that communications cease during the interval, defined by an interval period, offset within the interval period, and duration; the communication can be that of mobile devices to base stations in a wireless communication network. In this regard, base stations can measure thermal noise during the silence to set a interference over thermal (IoT) level in one example. Additionally, other systems and networks can use the silence intervals to transmit, such as public safety devices and/or peer-to-peer communication. The wireless mobile devices can receive the silence interval information and appropriately blank out communications during the defined period.

    Abstract: In a communication system wherein a CDMA segment at each access point consists of multiple sub-segments a three frame transmission time interval (TTI) with eight retransmissions is utilized for data transmission. The access point not only specifies the interlaces to be utilized for data transmission it also assigns packet start interlaces for particular access terminals. An auxiliary pilot channel R-AuxPICH is transmitted by an access terminal along with CDMA data on reverse link. The ratio of R-AuxPICH to R-PICH is varied based on ACK/NACK feedback. A reverse link activity bit (RAB) which can be used as an emergency load-control mechanism for non-QoS flows is also disclosed.
