Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: Wireless communication devices are adapted to facilitate non-orthogonal underlay transmissions. In one example, devices can receive a wireless transmission on a particular time and frequency resource including a first signal from a first wireless device and a second signal from a second wireless device. The first signal may utilize a first type of modulation for orthogonal wireless communication, and the second signal may utilize a second type of modulation non-orthogonal to the first type of modulation. The wireless communication device can decode the first and second signals. In another example, devices may transmit a first signal utilizing a first type of modulation over a time and frequency resource scheduled for a second signal from a second wireless communication device, the second signal utilizing a second type of modulation for orthogonal wireless communication, where the first type of modulation is non-orthogonal with the second type of modulation. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. A communications device may receive a downlink control message that supports indicating multiple modes for reporting hybrid automatic repeat request feedback, including a first mode for reporting hybrid automatic repeat request feedback and channel information according to a bundled configuration and a second mode for reporting hybrid automatic repeat request feedback according to a standalone configuration. The communications device may use the downlink control message to determine a mode for transmitting hybrid automatic repeat request feedback. The communications device may also transmit either bundled hybrid automatic repeat request feedback and channel information or standalone hybrid automatic repeat request according to the determined mode.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for the establishment of a communication link between a base station and a user equipment (UE). The UE may have a spatial partial reciprocity capability. The UE may be configured to determine antenna cross-correlation information for at least a first subset of antenna elements in the UE. The cross-correlation information may include one or more correlation parameters (e.g., correlation coefficients), a correlation model, or both. The UE may transmit sounding reference signals for a second set of antenna elements in accordance with the spatial partial reciprocity capability. The UE may also transmit an indication of the cross-correlation information for at least the first subset of antenna elements of the UE. The base station may use such information to derive correlation parameters for the unsounded antennas and determine precoders for downlink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may generate an uplink random access message, including a random access preamble and an uplink shared channel resource unit, of a two-step random access procedure. The UE may identify configuration information for uplink control information (UCI) multiplexing. The UE may identify a trigger for inclusion of UCI with the uplink random access message. The UE may multiplex the UCI and a reference signal with the uplink shared channel resource unit and map the uplink control information to resource elements in the uplink shared channel resource unit based on a priority of the uplink control information and a location of resource elements to which the reference signal is mapped. The UE may transmit the uplink random access message comprising the uplink control information and an indication of the used UCI configuration to the base station.

Abstract: This disclosure provides methods, devices, and systems for physical uplink shared channel (PUSCH) repetition based on support signaling, such as an uplink grant that includes a time domain resource assignment for transmitting one or more data repetitions that may cross a slot boundary. The UE may identify directions (for example, uplink, downlink, flexible) for one or more symbols spanning a transmission duration of the time domain resource assignment. The directions may be determined using a dynamic slot format indication (SFI), or semi-static SFIs may be used as a fallback (when dynamic slot format indications do not meet a target reliability). The uplink grant may include an indication of which symbol directions can be used for the one or more data repetitions. A subset of the one or more symbols for scheduling the one or more data repetitions may be determined based on the identified directions.

Abstract: 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.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for enabling a single media access control (MAC) layer to control a variety of physical (PHY) layers or entities for multiplexing signals corresponding to each of the PHY layers over an air interface. Here, the MAC layer may include a resource manager configured to determine a time-frequency resource allocation within the air interface for communication with one or more subordinate entities utilizing each of the PHY layers. In this way, The MAC entity may provide dynamic control over the allocation of time-frequency resources within a given resource group, which may include transmission time intervals (TTIs) having multiple time scales.
