Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for enhanced decoding, for example, by providing a multi-phase tail biting convolutional code (TBCC) decoding algorithm. An exemplary method generally includes obtaining, via a wireless medium, a codeword encoded with a TBCC encoding scheme, generating metrics for candidate paths through trellis stages of a decoder, propagating information from at least one of the trellis stages to a later trellis stage, while generating the metrics, selecting a set of the candidate paths based on the propagated information, and decoding the encoded codeword by evaluating the selected set of candidate paths based, at least in part, on the generated metrics. Other aspects, embodiments, and features are claimed and described.

Abstract: Various aspects described herein relate to hybrid automatic repeat/request (HARQ) communications in a wireless network. A first instance of a HARQ communication is transmitted or received over a first set of one or more links. Based on the transmitting or receiving the first instance of the HARQ communication, a scheduling grant can be received for a second instance of the HARQ communication over a second set of one or more links different from the first set of one or more links. The second instance of the HARQ communication can accordingly be transmitted or received over the second set of one or more links based at least in part on the scheduling grant.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a device to distinguish between signals transmitted using frequency modulated continuous wave (FMCW) waveforms. A first wireless device may apply a frequency-domain (FD) scrambling sequence to a reference signal for transmission, and a second wireless device may receive at least a portion of the signal and de-scramble the signal using the FD scrambling sequence. In some examples, the first wireless device may transmit configuration signaling indicating the FD scrambling sequence corresponding to the first wireless device. Additionally, or alternatively, the first wireless device may transmit an indication for the second wireless device to determine the FD scrambling sequence based on identifier (ID) information (e.g., an ID associated with the first wireless device). In some examples, the first wireless device, the second wireless device, or both may use analog or digital transceivers.

Abstract: The apparatus may be a wireless device configured to detect a first trigger condition at the wireless device and transmit, for a network device, a first indication to switch from a first mode of operation associated with a first data bandwidth and a first reference signal bandwidth to a second mode of operation associated with a second data bandwidth and a second reference signal bandwidth, where at least one of the second data bandwidth is smaller than the first data bandwidth and the second reference signal bandwidth is larger than the second data bandwidth, the first data bandwidth is smaller than the first reference signal bandwidth and the second data bandwidth is smaller than the second reference signal bandwidth, or the first data bandwidth is smaller than the second data bandwidth and the first reference signal bandwidth that is larger than the first data bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive encoded data from a network entity. The UE may decode the data in accordance with a size of the circular buffer. The UE, the network entity, or both may determine the size of the circular buffer based on a capability of the UE. In some examples, the size of the circular buffer may be associated with one or more limits for performing the decoding operation, including a limit for a quantity of encoded bits the UE can process during a sliding window. For example, the limits may consider any combination of a quantity of encoded bits or information bits that the UE may write to or write from a memory of the UE. In some cases, the limits may consider multiple bandwidth parts, multiple component carriers, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for avoiding collisions between hybrid automatic repeat request (HARQ) feedback transmissions and between HARQ feedback transmissions and other transmissions. In one example, a base station may configure resources for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In another example, a base station may indicate resources for a user equipment (UE) to use for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In yet another example, if a HARQ feedback transmission and another transmission are scheduled on overlapping resources, a UE may be configured to multiplex bits of the HARQ feedback transmission and the other transmission or drop the other transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may communicate an allocation of a set of time-frequency resources of a carrier for transmission of a first codeword. The first wireless device may map a first portion of the first codeword to resource elements of a first subband of the set of time-frequency resources in a frequency-first, time-second manner and a second portion of the first codeword to resource elements of a second subband of the set of time-frequency resources in the frequency-first, time-second manner. The first portion of the first codeword may include a contiguous portion of the first codeword preceding the second portion of the first codeword. The first wireless device may transmit, within the set of time-frequency resources, the first codeword based on the mapping.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a bundling factor, may first generate a codebook, and may then bundle a quantity of bits into a single bit according to the bundling factor (e.g., may compress the sequence of bits into a smaller, second set of bits, where each bit of the second set of bits represents a quantity of the sequence of bits equal to the bundling factor). The UE may support cross downlink control information (DCI) bundling, in which case each bundle of the sequence of bits may be based on the bundling factor, instead of being based on the DCI (e.g., a given bundle may include feedback bits corresponding to occasions of multiple grants).
