Provided are a codebook feedback method, a codebook feedback apparatus, a device, and a storage medium. The codebook feedback method includes: triggering, according to control information (CI), a hybrid automatic repeat request-acknowledgement (HARQ-ACK) codebook of a data channel group to perform feedback, where the CI includes at least one of: information of new feedback indication (NFI) corresponding to one or more data channel groups, a data channel group identifier and a group index corresponding to a currently scheduled data channel, or, a total downlink assignment index (T-DAI) corresponding to one or more data channel groups.

A physical sidelink feedback channel custom indication may be defined to indicate a half-duplex collision between one or more sidelink UE to a transmitting UE involved in the collision. In response to the indication, the transmitting UE may not retransmit the packet involved in the collision, and may stay awake for an extended period of time. A receiving UE that identified the collision and transmitted the indication may retransmit the packets involved in the collision to the transmitting UEs that have not yet received the respective packets.

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.

Methods and apparatuses for narrowband Internet-of-things (NBIoT) hybrid automatic repeat request (HARQ) related enhancement in a non-terrestrial network (NTN) are disclosed. A method comprises transmitting a control signal, the control signal includes at least one of a transmission repetition number index, a scheduling delay index, a resource assignment index, a NDI, a HARQ resource indication, and a MCS index; and transmitting or receiving a data signal based on the control signal, the data signal starts at the end of the control signal plus a first number of time slots, the data signal includes a second number of transmission repetitions of a third number of time durations.

A wireless device may receive a first TB associated with a first HARQ process number. The wireless device may determine to defer a first HARQ feedback, associated with the first TB, from a first timing to a second timing. The wireless device may receive, in a third timing, a second TB associated with the first HARQ process number. The wireless device may transmit the first HARQ feedback in the second timing or may drop the first HARQ feedback based on the second timing and the third timing.

A method for transmitting a HARQ-ACK by a UE is provided. The method receives an SPS configuration. The method then receives a DCI format which activates the SPS configuration and also indicates a first offset for transmitting the HARQ-ACK. After receiving an SPS PDSCH associated with the SPS configuration in a first slot, the method identifies a second slot based on the first slot and the first offset for transmitting the HARQ-ACK. The method determines whether a first PUCCH for transmitting the HARQ-ACK is contained within uplink/flexible symbols of the second slot. When the first PUCCH is not contained within the uplink/flexible symbols and also a parameter that is included in the SPS configuration indicates a deferred HARQ transmission, the method identifies a third slot based on the first slot and a second offset and transmits the HARQ-ACK on a second PUCCH in the third slot.

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.

According to an embodiment of the present disclosure, a method for performing sidelink communication by a first device is provided. The method comprises the steps of: transmitting at least one PSSCH to at least one reception device by using at least one sub channel and at least one slot in a resource pool; and receiving at least one HARQ feedback for the at least one PSSCH through at least one PSFCH resource from among M PSFCH resources in the resource pool, wherein the resource pool comprises K PSSCH-associated slots and L sub channels, which are associated with the PSFCH resources, M is greater than or equal to K*L, and K, L, and M may be positive integers.

Systems and methods for implementation of modified decision feedback equalization. In one embodiment, a method, includes sweeping a reference voltage signal across a set of voltages to find a center point of an eye diagram, determining whether an asymmetry is present in the eye diagram relative to the center point of the eye diagram, and when an asymmetry is determined to be present, generating a control signal to select a mode of decision feedback equalization to be applied to an input data bit.

There is provided an apparatus comprising means for receiving, at an analytics function from a first network function, a request for one or more timer adjustments for at least one timer associated with one or more network functions; obtaining, by the analytics function from one or more further network functions, one or more input parameters relating to network behaviour; and sending, from the analytics function to the first network function, an output comprising one or more timer adjustments for the at least one timer, wherein the output is based on the obtained one or more input parameters.
