Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

Abstract: Techniques are described herein for coding video content using recurrent-based machine learning tools. A device can include a neural network system including encoder and decoder portions. The encoder portion can generate output data for the current time step of operation of the neural network system based on an input video frame for a current time step of operation of the neural network system, reconstructed motion estimation data from a previous time step of operation, reconstructed residual data from the previous time step of operation, and recurrent state data from at least one recurrent layer of a decoder portion of the neural network system from the previous time step of operation. A decoder portion of the neural network system can generate, based on the output data and recurrent state data from the previous time step of operation, a reconstructed video frame for the current time step of operation.

Abstract: Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to techniques that may help reduce or eliminate ambiguity in acknowledging multiple physical downlink shared channel (PDSCH) transmissions in a single transmission time interval (TTI). According to aspects, a codebook with fewer fields than a number of PDSCH candidates may be used to provide acknowledgement/negative acknowledgement (ACK/NACK) feedback.

Abstract: Techniques are described for wireless communication. One method includes identifying a transmission time interval (TTI)-level control region, where the cascaded control region includes a TTI-level common control region and a TTI-level UE-specific control region, and where the TTI-level common control region has a pointer to a location of the TTI-level UE-specific control region; and demodulating at least one of the TTI-level common control region and the TTI-level UE-specific control region. Some techniques enable control information in a first region to point to a second region that includes additional control information. Some techniques enable two-stages of control. Semi-persistent scheduling/prescheduling control may be configured to cause an entity to refrain from demodulating one of the stages of control.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

Abstract: Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

Abstract: Wireless communications systems may support user equipment (UE)-specific hybrid automatic repeat request (HARQ) timeline offsets such that transmission time intervals (TTIs) reserved for uplink HARQ transmissions are reserved on a per UE basis (e.g., TTIs are not reserved or designated on a network level or aligned across all or many UEs within the system). That is, UEs within a wireless communications system may employ a UE-specific offset for their respective HARQ timelines. UE-specific HARQ timeline offsets may be derived, by the UEs, explicitly or implicitly. Further, the network (e.g., a base station) may configure UE-specific HARQ timeline offsets to be distributed in time to avoid uplink HARQ transmission collisions between UEs, to eliminate the loss of TTIs for a second carrier operation (e.g., such as NR uplink) on a network wide basis, etc. The base station may then communicate with the UEs according to their corresponding UE-specific offset HARQ timelines.

Abstract: Systems and methods herein increase the throughput and decreases the collisions of transmitted resource element group (REG) bundles. Prior to transmitting a PDCCH comprising REG bundles, one or more processors perform a multi-component interleaver process that diversifies and randomizes the sequence of the REG bundles while also supporting CORESETs having different symbol lengths. In embodiments, the multi-component interleaver diversifies a virtual sequence of REG bundles using a block interleaver and then uses a randomizer interleaver to randomize the output sequence of the block interleaver. The diversified and randomized output sequence of REG bundles may be the physical channel sequenced of the REG bundles. The physical channel sequence of REG bundles is diversified and randomized such that the physical sequence increases throughput and decreases the collisions of transmitted REG bundles. Other aspects are claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to block puncture or to block shorten a set of transmitted bits of an adjusted fractally enhanced kernel polar code for a communication of an incremental redundancy (IR)-hybrid automatic repeat request (HARQ) process based at least in part on a code rate associated with the communication of the IR-HARQ process. The wireless communication device may generate the adjusted fractally enhanced kernel polar code for the communication based at least in part on determining to block puncture or to block shorten the set of transmitted bits. The wireless communication device may transmit the communication using the adjusted fractally enhanced kernel polar code. Numerous other aspects are provided.
