Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for increasing decoding performance and/or reducing decoding complexity. An exemplary method generally includes receiving, via a wireless medium, a codeword encoded using a tailless convolutional code (TLCC) with a known start state, evaluating a set of decoding candidate paths through a trellis decoder that originate at the known start state of the TLCC, performing, for each of a plurality of the decoding candidate paths, a back trace from a respective end state to the known start state, and selecting one of the decoding candidate paths based, at least in part, on path metrics generated while performing the back trace. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Abstract: Wireless communications systems and methods related to a coupled mode common uplink burst in Time Division Duplex (TDD) sub-frame structure are disclosed. Upon receiving a signal requesting a user to transmit a sounding reference signal (SRS) and a control channel within a common uplink (UL) burst in each sub-frame communicated between the user and a base station, the user transmits the common UL burst comprising the SRS coupled with the control channel spanning the same frequency bandwidth.
