Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to identify, by a user equipment of a communication network, downlink control information (DCI) indicating that at least one hybrid automatic repeat request-acknowledgment (HARQ-ACK) codebook scheduled earlier for transmission needs to be re-transmitted in a physical uplink control channel (PUCCH) occasion indicated by the DCI and identifying which at least one HARQ-ACK codebook scheduled earlier for transmission needs to be re-transmitted in the PUCCH occasion. And based on the DCI, prepare the PUCCH for re-transmitting the identified at least one HARQ-ACK codebook in the PUCCH occasion. Further, to determine and transmit, by a network equipment of a communication network, the DCI to the user equipment of the communication network and to receive the PUCCH for re-transmitting the at least one HARQ-ACK codebook in the PUCCH occasion from the user equipment.

Abstract: A method may include receiving, by a user equipment from a network entity, a first downlink (DL) control signal activating semi-persistent scheduling (SPS) of a first set of downlink data transmissions, the downlink control signal indicating an applicable hybrid automatic repeat request (HARQ) feedback timing for the first set of downlink data transmissions and receiving one or more of the first set of downlink data transmissions. The user equipment may determine that an applicable HARQ feedback timing for a second set of downlink data transmission previously received with an inapplicable HARQ feedback timing has not been provided. In response to the determination, the user equipment may determine a HARQ feedback timing for the one or more of the first set of downlink data transmissions based a second DL control signal indicating an applicable HARQ feedback timing received after reception of the one or more of the first set of downlink data transmissions.

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: It is provided a method, comprising checking if an option grant for an uplink transmission is received, wherein the option grant comprises, for a subframe, a first allocation option to start the uplink transmission and a second allocation option to start the uplink transmission, wherein the first allocation option is earlier in the subframe than the second allocation option; deciding if the uplink transmission is allowed at the first allocation option; starting the uplink transmission at the first allocation option if the option grant is received and the uplink transmission is allowed at the first allocation option; deciding if the uplink transmission is allowed at the second allocation option; starting the uplink transmission at the second allocation option if the option grant is received, the uplink transmission is not allowed at the first allocation option, and the uplink transmission is allowed at the second allocation option.

Abstract: According to an example embodiment, a method may include receiving, by a user device in a wireless network, an uplink grant, the uplink grant indicating granted resources having a priority level; determining, by the user device, whether or not information to be transmitted has a priority level that matches the priority level of the granted resources; and transmitting, by the user device, the information via at least a portion of the granted resources, and an indication of whether or not a priority level of the information matches a priority level of the granted resources.

Abstract: A method is provided including: transmitting an uplink grant to a user equipment indicating a plurality of scheduled transmission time intervals within a continuous wideband resource allocation over a plurality of sub-channels; attempting to receive a plurality of first transmissions from the user equipment in each of one or more first transmission time intervals of the transmission time intervals, where each of the first transmissions in each of the first transmission time intervals corresponds to a different one of the sub-channels and corresponds to a different hybrid automatic repeat request process; attempting to receive a further transmission from the user equipment in each of the transmission time intervals following the first transmission time intervals, where each further transmission corresponds to a further hybrid automatic repeat request process; and determining a hybrid automatic repeat request process identifier for each successfully received first transmission and for each successfully received further transmission.

Abstract: Various communication systems may benefit from the appropriate handling of multiple competing transmissions. For example, high or ultra reliable low latency communication systems may benefit from cycling hybrid automatic repeat request transmission processes for grant-less uplink transmission. A method can include identifying or predicting a plurality of pending data transmissions. The method can also include deterministically cycling the pending data transmissions among a plurality of available resources.

Abstract: A radio network sends to a user equipment (UE) an indication that reduced processing time associated with a reduced search space is operational for the UE. The reduced search space is a sub-set of a larger search space associated with a non-reduced processing time. The network sends to the UE within the reduced search space downlink control information (DCI) in subframe N that allocates to the UE a radio resource. If the allocated radio resource is uplink, the network receives uplink data from the UE on the allocated radio resource in a subframe spaced from the subframe N an amount of the reduced processing time (N+reduced processing time); and/or if the allocated radio resource is downlink the network sends downlink data to the UE on the allocated radio resource in subframe N and receives from the UE in reply feedback (ACK/NACK) signaling in a subframe N+reduced processing time.

Abstract: Systems, methods, apparatuses, and computer program products for packet combining for PDCP duplication, e.g., in ultra-reliable low-latency-communication (URLLC) scenarios are provided. One method may include providing, from a network node to at least one second node, a pointer to an earlier or first transmission of a protocol data unit (PDU). The pointer may be used by subsequent transmissions of the protocol data unit (PDU) through the at least one second node to indicate to a user equipment (UE) what transmissions are to be combined.
