摘要： A system and method for low latency acknowledgements includes a first communication unit receiving a data message from a second communication unit on a data channel, decoding the data message, and transmitting, in response to the decoding, an acknowledgement signal on a control channel to the second communication unit. The acknowledgement signal has a partially decodable structure. Transmitting the acknowledgement signal further includes transmitting multiple repetitions of a same time domain waveform during one symbol period. In some embodiments, transmitting the acknowledgement signal further transmitting K repetitions of a same time domain waveform with a frequency domain characteristic consisting of one non-zero tone for every K tones, K being a positive integer. In some embodiments, the acknowledgement signal is processable by the second communication unit using a first N out of the K repetitions, N being a positive integer less than K.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, wireless devices may implement adjusted fractally enhanced kernel polar coding. An encoder may receive a number of information bits and a block size for transmission, and may append an additional number of information bits to the information bits for transmission. The encoder may perform a recursive bit allocation process to allocate the aggregate set of information bits between a set of sub-blocks based on mutual information metrics. To obtain the correct number of information bits and block size, the encoder may remove a number of information bits equal to the number of appended additional bits (e.g., from a first half of the sub-blocks), assign the remaining information bits to bit channels in each sub-block, and block puncture a set of bits (e.g., from the first half). The resulting codeword may mitigate occurrences of achievable signal-to-noise ratio (SNR) spikes.

摘要： Methods, systems, and devices for wireless communications are described. A wireless communications system may support multicast transmissions from a base station to multiple user equipments (UEs). Each UE may have uplink resources allocated for providing feedback to the base station regarding multicast transmissions. For example, a UE may not successfully decode one or more frames of a multicast transmission. When a UE does not successfully decode the one or more frames, the UE may transmit negative acknowledgment (NACK) feedback indicating the one or more frames that were not successfully received. A serving base station may store frames within a buffer for a transmission window and retransmit each of the frames indicated within the NACK feedback from the stored frames. In some cases, the serving base station may not retransmit frames that were not indicated within the NACK feedback (e.g., frames that may have been received successfully by the UE).

摘要： Methods, systems, and devices for wireless communication are described. The method, systems, and devices may include receiving a plurality of sets of input bits associated with respective transmission symbol periods at an encoder of a transmitting device, the plurality of sets of input bits associated with a single input vector to be encoded into a single codeword. The encoder may process the plurality of sets of input bits to generate a plurality of sets of output bits associated with respective transmission symbol periods, and output a first of the plurality of sets of output bits associated with a first of the plurality of sets of input bits prior receiving a second of the plurality of sets of input bits, the second of the plurality of sets of input bits being received at the encoder subsequent to the first of the plurality of sets of input bits.

摘要： Aspects of the present disclosure provide a code block group (CBG) based HARQ retransmission process in which HARQ retransmission is performed based on CBG units. The CBG based HARQ process uses a CBG failure mask that can reduce the signaling overhead of CBG-based HARQ retransmissions. A base station can determine the error CBGs from different UEs that share a slot, and generate a CBG failure mask that capture all the CBGs NACKs from the UEs.

摘要： Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or other base stations); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method of wireless communication includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or other base stations); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.

摘要： Methods, systems, and devices for wireless communication are described. A wireless communication network may support mission critical (MiCr) communications and mobile broadband (MBB) communications with hybrid multiplexing (e.g., time division multiplexing (TDM) and frequency division multiplexing (FDM)). A base station may identify a first set of resources allocated for MiCr communications and a second set of resources allocated for MBB communications. The first and second set of resources may be multiplexed in the frequency domain, and the base station may transmit MiCr information over the first set of resources under normal data traffic conditions. As data traffic or other conditions associated with MiCr communications change, the base station may schedule MiCr transmissions on the second set of resources allocated for MBB communications, by puncturing the second set of resources for the MiCr communications.

摘要： Methods, systems, and devices for wireless communication are described that provide for uplink channel multiplexing and waveform selection. Uplink channels to be transmitted from one or more user equipment (UEs) to a base station are multiplexed together or separately into an uplink subframe. Each UE is capable of using different waveforms to transmit different channels. Reference signals are communicated according to an RS pattern, which is symmetric across uplink and downlink channels.

摘要： Methods, systems, and devices for wireless communication are described that support channel selection for parity bits in polar coding techniques. In some cases, an encoder or decoder of a wireless device may assign information bits, frozen bits, and parity check bits to polar channels of an encoder or decoder based on reliability metrics. The information bits may initially be assigned and based on a channel index of the first information bit, the parity check bits may be assigned to channels having higher channel indices than the first information bit. After assignment, the bits may be encoded or decoded.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple physical downlink control channels (PDCCHs) in one or more slots along with data traffic, where one of the PDCCHs includes a downlink preemption indication (DLPI) signifying that a portion of the data traffic was preempted. In some cases, the UE may monitor, within a same slot, for both the data traffic and an additional PDCCH carrying the DLPI and then transmit, within the same slot, a feedback message based on attempting to decode the data traffic, taking into account the DLPI. Additionally, the UE may receive the data traffic via a first service, where the DLPI indicates a second service preempts the first service. In some cases, the DLPI may be transmitted based on the UE being capable of processing the data traffic and transmitting the feedback message within the same slot.
