Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for terminating HARQ retransmissions. A wireless receiver may determine that a transmission of a first TB based on a first redundancy version is not received from a wireless transmitter. Based on the determination, the wireless receiver may transmit, to the wireless transmitter, a HARQ ACK to terminate one or more HARQ retransmissions associated with the different redundancy versions of the first TB.

Abstract: Techniques and apparatus for using downlink control information (DCI) to avoid hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One example technique involves a user equipment (UE) receiving an indication of a plurality of SPS configurations, each SPS configuration allocating the UE with a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. Information for resolving a conflict between a first HARQ process ID associated with a first SPS occasion of a first of the plurality of SPS configurations and a second HARQ process ID associated with a second SPS occasion of a second of the plurality of SPS configurations is received. The first SPS occasion occurs prior to the second SPS occasion. The conflict is resolved based on the information.

The method also includes receiving, by the network device, the TB from a terminal on the non-dynamic resource according to the HARQ ID.

Abstract: A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via a sidelink sub-channel of a primary carrier, an indication that identifies one or more resources on the primary carrier for transmitting one or more hybrid automatic repeat request (HARQ) responses for one or more sidelink communications between the first UE and the second UE on a secondary carrier; and receive, from the second UE, on the one or more resources on the primary carrier, the one or more HARQ responses for the one or more sidelink communications on the secondary carrier. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions across multiple transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the TTIs being indicated as passing the LBT channel access procedure based on the performance.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: A wireless device receives one or more radio resource control (RRC) messages. The RRC messages comprise: one or more first feedback parameters for selecting first feedback radio resources of a sidelink; and one or more second feedback parameters for selecting second feedback radio resources of the sidelink. A sidelink transmission comprising sidelink control information (SCI) indicating a priority level of the sidelink transmission is received. Based on the priority level, one or more radio resources are selected from one of: the first feedback radio resources based on the one or more first feedback parameters; and the second feedback radio resources based on the one or more second feedback parameters. A hybrid automatic repeat request (HARQ) feedback for the sidelink transmission is transmitted via the selected one or more radio resources.

Abstract: Systems and methods are disclosed for dynamic Hybrid Automatic Repeat Request (HARQ) codebook construction with enabling or disabling of HARQ Acknowledgment (HARQ-ACK) feedback per HARQ process. In one embodiment, a method performed by a wireless communication device comprises receiving, from a network node, information that configures the wireless communication device with a first set of HARQ processes for which HARQ-ACK feedback is disabled and a second set of HARQ processes for which HARQ-ACK feedback is enabled. The method further comprises receiving first downlink control information that schedules a first downlink shared channel transmission and determining that the transmission corresponds to one of the first set of HARQ processes for which HARQ-ACK feedback is disabled. The method further comprises, upon making this determination, performing a first set of actions for HARQ-ACK feedback generation for HARQ processes with HARQ-ACK feedback disabled.

The TB or the SPS configuration may be associated with a first priority or a second priority. The wireless device may transmit a feedback via an unlicensed cell. Transmitting the feedback may be based on a first value of an unlicensed parameter in response to the TB or the SPS configuration being associated with the first priority. Transmitting the feedback may be based on a second value of the unlicensed parameter in response to the TB or the SPS configuration being associated with the second priority.

Abstract: Configuration data associated with a router is converted. A selector tool identifies a first port of a first router having first data lines, and identifies a second port of a second router to receive the first data lines to be migrated from the first port. The first router and the second router use different, incompatible configuration data formats. A data transceiver captures first port configuration data associated with the first port of the first router, and a configuration data converter is to identify a type of interface associated with the captured first port configuration data and convert the captured first port configuration data from a first format compatible with the first router to a second format compatible with the second router based on the identified type of interface. A conversion file generator generates a configuration file containing the converted first port configuration data in the second format.
