One embodiment of the present invention relates to a method for transmitting, by a terminal, feedback on a signal from another terminal in a wireless communication system. The method for transmitting feedback information comprises the steps of: receiving signals transmitted by a plurality of terminals; and transmitting feedback information on each of at least parts of the received signals, wherein the feedback information is transmitted together with data of the terminal transmitting the feedback information, and the feedback information includes time information that allows the terminals that transmitted each of the parts of signals that are subject to the feedback to recognize that the feedback information is feedback on the signals transmitted by the same terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

Certain aspects of the present disclosure are directed to techniques for hybrid automatic repeat request (HARQ) codebook design. For example, a user equipment (UE) configured for feedback processing may comprise a memory and a processor configured to receive, from a base station (BS), a first indication of a first feedback process type for providing feedback to the BS for a plurality of feedback processes of the UE. The memory and the processor may also be configured to receive one or more first downlink transmissions from the BS associated with at least one feedback process of the plurality of feedback processes. The memory and the processor may also be configured to transmit feedback or withhold transmission of feedback to the BS regarding decoding of the one or more first downlink transmissions according to the first feedback process type.

The present disclosure provides a method and a device in a communication node for wireless communications. The communication node in the present disclosure first receives first information, and then transmits a first radio signal; a length of a time interval between a start time for transmitting the first radio signal and a first reference time is equal to a sum of a first timing adjustment and a second timing adjustment, the first timing adjustment being one of X candidate timing adjustments, the X being a positive integer greater than 1; the second timing adjustment is used for determining a transmission timing of a radio signal transmitted before the first radio signal in time domain; a transmitter of the first radio signal determines the first timing adjustment out of the X candidate timing adjustments by itself. The present disclosure can improve uplink synchronization performance.

The technologies described herein are generally directed to changing error mitigation protocols used for a connection based on the quality of a network connection in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include determining, by network equipment comprising a processor, that a quality of a connection between a user equipment and a network access point is below a connection quality threshold, with the connection employing a communications protocol using a first error mitigation process, and where the network access point enables respective access to services enabled via a communication network. The method can further include, based on the quality and the first error mitigation process, enabling, by the network equipment, a second error mitigation process of the communications protocol of the connection, the second error mitigation process being different than the first error mitigation process.

Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

A wireless device, network node and a method for managing a hybrid automatic repeat request (HARQ) process for grant-free uplink access. The method includes transmitting data to a network node during a first time slot corresponding to a first PID according to a first mapping. The method further includes receiving a HARQ feedback signal indicating one of an acknowledgement, ACK, and a non-acknowledgement, NACK, associated with the first PID. When a NACK is received, an indication of a second time slot for a retransmission is received. The data corresponding to the first PID is retransmitted during the second time slot.

A method for determining a contention window size (CWS) is applied to a network device and includes determining hybrid automatic repeat request-acknowledgement (HARQ-ACK) information corresponding to a physical downlink shared channel (PDSCH) transmitted on a reference time unit on a first unlicensed carrier; and determining a first CWS according to the HARQ-ACK information, wherein the first CWS is used for performing channel detection on the first unlicensed carrier.
