Abstract: A method, apparatus, and a computer-readable storage medium are provided for constructing a HARQ-ACK codebook for managing the trade-off between codebook size and feedback granularity. In an example implementation, the method may include a network node determining a second time domain resource allocation table and transmitting configuration information to the UE. The method may further include the network node transmitting downlink data to the UE and receiving the one or more ACKs and/or NACKs from the UE in response to the transmitting of the downlink data, the one or more ACKs/NACKs being generated based at least on the second time resource allocation table. In another example implementation, the method may include a user equipment (UE) receiving configuration information from a network node, receiving downlink data from the network node, and transmitting one or more ACKs/NACKs to the network node.

Abstract: A technique includes multiplying, by a user device, a first uplink control information, associated with a first control channel format length, with a first orthogonal signal to obtain a first spread control signal, multiplying, by the user device, a second uplink control information, associated with a second control channel format length, with a second orthogonal signal that is different than the first orthogonal signal to obtain a second spread control signal, the second control channel format length being different than the first control channel format length, receiving, by the user device, a first resource grant indicating one or more resource blocks for uplink transmission, the first resource grant associated with or provided for the first uplink control information, and transmitting, by the user device, at least partially simultaneously via the one or more resource blocks, the first spread control signal and the second spread control signal.

Abstract: A technique is provided for receiving, by a user device from a base station, a control signal indicating that base station-triggered reference signals will be transmitted to the user device, and receiving, by the user device, the base station-triggered reference signals on a set of time-frequency resources in at least one physical downlink control channel (PDCCH) search space.

Abstract: Systems, methods, apparatuses, and computer program products for supporting different downlink and/or uplink processing times on a serving cell are provided. This can be used, for example, to support mixed enhanced mobile broadband (eMBB) and/or ultra-reliable low-latency communication (URLLC) traffic on the cell.

Abstract: A system, apparatus, method, and non-transitory computer readable medium for providing transfer block indications in uplink (UL) grant-free transmissions may include a memory having computer readable instructions stored thereon, and at least one processor configured to execute the computer readable instructions to transmit a first transport block (TB) to a base station (BS) during a first transmission time interval (TTI) using a grant-free UL transmission, receive a UL grant from the BS in a physical downlink control channel (PDCCH) region during a time window, determine a target of the UL grant, the target including at least one of the first TB, a second TB, or a previously transmitted TB, based on the UL grant, and transmitting the target of the UL grant to the BS.

Abstract: A method may include receiving, from a network node, association and configuration information for a plurality of sequences, where each sequence may be associated to at least one network-node beam or beam-pair link. The method may also include performing beam measurements of beams from the network node to obtain beam measurement information. The method may further include detecting beam misalignment of the beam based on the beam measurement information. In addition, the method may include transmitting a sequence among the plurality of sequences to the network node to inform the network node of the beam misalignment, and to trigger the network node to start a beam adjustment procedure and a monitoring procedure for a configured-grant configuration. Further, the method may include, after transmitting the sequence, considering the indicated preferred beam as a new serving beam, and switching to the configured-grant configuration associated with this new serving beam.

Abstract: According to a first embodiment, a method may include receiving, by a user equipment, at least one downlink assignment indicating at least one multiplexing group indicator. The method may further include generating, by the user equipment, at least one hybrid automatic repeat request acknowledgement codebook in a sub-slot for each received multiplexing group indicator value. The method may further include determining, by the user equipment, whether more than one PUCCH resource associated with more than one multiplexing group indicator overlaps in time. The method may further include transmitting, by the user equipment, the highest priority codebook on the determined PUCCH resource and preventing, by the user equipment, transmission of the lower-priority HARQ-ACKs based on the at least one MGI indication in case an overlap in time has been determined. The method may further include transmitting, by the user equipment, the generated codebook on the determined PUCCH resource.

Abstract: Various communication systems may benefit from improved signaling. For example, anew radio communication system may benefit from a flexible indication of transmission timing. A method may include determining, at the user equipment, transmission timing based on a first parameter and a second parameter. The first parameter may indicate an offset as a number of slots. The second parameter may indicate an offset as a number of symbols within one of the slots. The method may also include using the transmission timing to at least one of send an uplink transmission or receive a downlink transmission.
