09565231 · 2017-02-07 · ·

Systems and methods are described for providing multiple voice service modes to a wireless device using data packet transmission through a wireless network. Application requirements including a signal level threshold for a wireless device may be determined. Signal level information for the wireless device may be received and transmitted among various network nodes. The received signal level may be compared with the signal level threshold for the wireless device. The wireless device and the access node may communicate wirelessly to provide voice services to the wireless device application. Data transmission may be converted between a first mode and a second mode depending upon a relative position of the received signal level with respect to the signal level threshold. The second mode of data transmission may be used where the first mode of data transmission cannot because the second mode may consume less network resources.

METHODS AND MODULES FOR QUALITY OF SERVICE PROVISIONING IN LINK ADAPTATION

The present disclosure relates to methods and modules for link adaptation in a network system comprising an access point (AP) linked to one or more stations through one or more links. The stations generate a set of quality of service provisioning link adaptation (QPLA) parameters, which comprise a data rate requirement, a packet error rate (PER) requirement, and a performance preference. The AP receives the QPLA parameters and determines link adaptation for each of the one or more stations based on the QPLA parameters.

SYSTEMS AND METHODS OF FORWARD ERROR CORRECTION FOR CELLULAR COMMUNICATIONS

Systems and methods for forward error correction for cellular communication may include an endpoint which receives, from a wireless communication node, an indication of a portion of packets which are to be dropped by the wireless communication node, according to a first forward error correction (FEC) ratio. The endpoint may receive quality of service (QOS) feedback from another endpoint. The endpoint may determine whether to switch from the first FEC ratio to a second FEC ratio, according to the QoS feedback and the indication.

User equipment feedback on number of repetitions needed for decoding

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transport block (TB). The UE may fail to successfully decode the TB. The UE may transmit a negative acknowledgement (NACK) message based at least in part on the failing to successfully decode the TB. The NACK message may indicate a quantity of repetitions for retransmitting the TB. Numerous other aspects are described.

Reliable link quality estimation in multi-rate networks

Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.
