A discontinuous transmission or reception configuration method includes: acquiring target configuration information for configuring a target discontinuous transmission or reception mode on at least one carrier; and performing transmission according to the target configuration information; where the target discontinuous transmission or reception mode includes at least one of a Uu discontinuous transmission or reception mode used by a UE with a sidelink resource allocation mode and a sidelink discontinuous transmission or reception mode. Also disstopd are user equipment for configuring a discontinuous transmission or reception mode and a readable storage medium storing a computer program of the discontinuous transmission or reception configuration method. The target discontinuous transmission or reception mode can meet a sidelink service requirement and a Uu service requirement at the same time, and improve the energy efficiency of a communication system.

The present disclosure provides a method and device for sidelink wireless communications. A first node transmits a first signaling and a first radio signal; monitors a second signaling; maintains a first counter according to whether the second signaling is received; and as a response to a value of the first counter reaching a first threshold, determines an RLF for a second node; the behavior of maintaining a first counter according to whether the second signaling is received comprises: when the second signaling is received, updating the value of the first counter to an initial value; when the second signaling is not received and a time for transmitting the first signaling belongs to an active estimation time, updates the value of the first counter by 1. The application reduces the risk of triggering unnecessary Radio Link Failure (RLF).

The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: based on the UE transmitting the UL data on a UL resource of a configured grant (CG) configuration based on a Hybrid-ARQ (HARQ) process, starting a CG timer for the HARQ process; based on retransmission of the UL data based on the HARQ process not being performed until expiration of the CG timer, determining that a transmission of the UL data is not successful; and performing retransmission of the UL data based on the HARQ process after the expiration of the CG timer.

The present invention provides a method and system of periodic transmission of data between a first entity and a second entity within a mobile communication network. In order to increase transmission quality and take into account application characteristics of the network entities the first entity is able to obtain an adverse response from the second entity and provide an ancillary message to the second entity, where the ancillary message may have different contents depending on transmission circumstances, with the aim to increase the quality of transmission and to ensure the application requirements are met in different situations.

A method for enabling Configured Uplink with repetition in a wireless communications system. In examples discussed herein, a wireless device (e.g., a user equipment) receives a configured number of repetitions from a base station (e.g., an eNB). Accordingly, the wireless device repeats a Transport Block (TB) corresponding to a Physical Uplink Shared Channel (PUSCH) transmission across an equal number of consecutive PUSCHs as the configured number of repetitions. As a result, the wireless device can support Configured Uplink with repletion, for example, when the repetition is configured for New Radio Unlicensed band (NR-U) Configured Uplink.

Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Methods, systems, and devices related to related to digital wireless communication, and more specifically, to techniques related to an improved repetition transmission method. In one exemplary aspect, a method for wireless communication is disclosed. The method can include receiving, at a terminal configured to perform a number of transmission repetitions according to a rule, a first message from a network node, the first message including an indication to modify at least one transmission repetition of the number of transmission repetitions according to the rule. The method can also include modifying, by the terminal, the at least one transmission repetition of the number of transmission repetitions identified in the first message.

A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.
