Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs, The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a base station has scheduled the UE for one or more downlink transmissions, each of the one or more downlink transmissions having an associated repetition factor that corresponds to one of a plurality of configured repetition factors configured at the UE. The UE may identify an applied repetition factor to apply to feedback codebook generation for the one or more downlink transmissions. The UE may generate a feedback codebook for reporting feedback for the one or more downlink transmissions, the feedback codebook populated based at least in part on the applied repetition factor and on whether the one or more downlink transmissions were successfully received and decoded. The UE may transmit to the base station a feedback report that includes the feedback codebook.

A wireless device receives a radio resource control (RRC) message that includes configuration parameters for scheduling a plurality of physical uplink shared channels (PUSCHs) via a downlink control information (DCI). In an embodiment, the configuration parameters may include an indication enabling a dynamic determination of a PUSCH of the plurality of PUSCHs for multiplexing an uplink control information (UCI). In an additional embodiment, the UCI may overlap with a first PUSCH of the plurality of PUSCHs. The wireless device may transmit the UCI via a second PUSCH of the plurality of PUSCHs in response to a failed listen-before-talk (LBT) procedure for the first PUSCH.

Certain aspects of the present disclosure provide techniques for cross layer improvement with radio link control feedback on physical layer. In aspects, a method performed by a user equipment (UE) includes receiving a radio link control (RLC) packet; and transmitting, in response to the RLC packet, an RLC acknowledgment (ACK) or an RLC negative acknowledgment (NACK) on a pre-configured uplink resource associated with the RLC packet.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a first terminal in a communication system is provided. The method includes transmitting data of a physical side link shared channel (PSSCH) and sidelink control information (SCI) associated with the data, and receiving, from a second terminal, a hybrid automatic repeat request (HARQ) feedback for the data, wherein the HARQ feedback is performed based on a distance between the first terminal and the second terminal, in case that the SCI includes location information of the first terminal.

A wireless device receives one or more configuration parameters including a plurality of sidelink feedback resources, where at least two sidelink feedback resources, of the plurality of sidelink feedback resources, are associated with different values for received signal power, and each of the at least two sidelink feedback resources are at least one of a time resource or a frequency resource. The wireless device selects, based on a received signal power of the different values for the received signal power, a sidelink feedback resource from the at least two sidelink feedback resources. The wireless device transmits a sidelink feedback signal, to a second wireless device, via the sidelink feedback resource.

A basestation (e.g., a gNodeB) may transmit transmission scheduling information (such as downlink control information) to user equipment (UE). The basestation may include repetition related parameters (such as repetition numbers, aggregation factors, or other repetition information) for transmission repetition control within the transmission scheduling information.

A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.

Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA via a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a band of 320/160+160 MHz including a primary channel of 160 MHz and a secondary channel of 160 MHz, the data field is received via a first multiple RU in which a 996-RU and a 484-RU are aggregated. The first multiple RU is allocated within the primary channel of 160 MHz or the secondary channel of 160 MHz.

A method for controlling block acknowledgement feedback includes: for multiple transmission links for transmitting continuous data frames, sending a block acknowledgement feedback control identifier from a first communication device to a second communication device. The block acknowledgement feedback control identifier is configured to indicate an enabled or disenabled state of block confirmation feedback of the transmission link.
