Abstract: According to an aspect, a first node determines that transmission of a packet to a second node failed. A cause for the failed packet transmission is determined as a function of a comparison between one or more signal parameters and one or more predetermined thresholds. The cause is either channel impairment or packet collision. The first node selects either to adjust one or more link adaptation parameters or to adjust one or more collision avoidance parameters for succeeding packet transmissions responsive to the determined cause. The link adaptation parameters are adjusted responsive to the cause being determined to be channel impairment, and the collision avoidance parameters are adjusted responsive to the cause being determined to be packet collision.

Abstract: Methods, systems, and devices are described for identifying and mitigating in-device coexistence interference for multicarrier systems implementing soft combining decoding techniques. In some aspects, the described techniques include identifying time-frequency resources of a received signal subject to coexistence interference at a transceiver of a wireless device. The time-frequency resources may include, for example, symbols, slots, code-blocks, sub-frames, subcarriers, etc . Resource-specific mitigation may then be applied to the identified resources, for example, including skipping or nulling the interfered resources in the time domain, frequency domain, or both. In some aspects, the resource-specific mitigation may be performed at the soft-combining stage of the decoding process, such as by skipping or nulling one or more log likelihood ratio (LLR) instances that correspond to the interfered resource(s).

Abstract: Techniques for detecting discontinuous transmission (DTX) are disclosed. In an example method, given a sequence of bits that is known by a wireless receiver to be included in transmission bursts targeted to the wireless receiver and given a series of received signal samples corresponding to an expected transmission burst for the wireless receiver, the wireless receiver estimates a channel response and a location for the sequence within the series. The wireless receiver generates a plurality of bit estimates from the subset of received signal samples, based on the estimated channel response, compares the bit estimates to bits in the sequence of bits, and determines whether a valid burst for the wireless receiver is present, based on said comparing. The disclosed techniques are particularly suitable for use in detecting DTX in VAMOS scenarios.

Abstract: Methods and apparatus are disclosed for estimating a quality of a received data frame in a trellis decoder. The decoder utilizes a trellis diagram to depict the states and stages the decoder transitions through in search of a sequence of bits that closely resemble the received sequence. In the trellis diagram, each state at one stage is connected to a state at the next stage by a branch and a group of connected branches form a path. The decoder selects a winning path by comparing path metrics computed for each of the paths in the trellis diagram and outputs a most-likely sequence of hard bits from the winning path. A count of non-ideal branches over the winning path can be used for calculating the frame quality of the received data frame or the burst quality of a data burst in the received data frame.

Abstract: Apparatus and methods for selective decoding of received code blocks are disclosed. An example method includes receiving a code block, determining a code block quality indicator for the received code block, and attempting to decode the received code block if the code block quality indicator is greater than or equal to a threshold. If the code block quality indicator is less than the threshold, the received code block is discarded without decoding attempts. The threshold may be a static or dynamic threshold.
