The present disclosure provides a method and a device used for discontinuous reception. A first node monitors a first signal in a first time resource pool, a first bit block is used to generate the first signal, the first bit block comprises a MAC PDU, and the first bit block comprises a first identification component; and a second receiver, when the first signal is successfully received in the first time resource pool, monitors a first signaling in a first time-frequency resource block; when the first signal is not successfully received in the first time resource pool, drops monitoring a first signaling in a first time-frequency resource block. The application can avoid the introduction of sidelink MAC CE to maintain the compatibility with the existing standards as far as possible; in addition, the application can reduce the overhead of air interface.

A first node transmits a first physical-layer signaling and a first Medium Access Control (MAC) Protocol Data Unit (PDU) via an air interface. The first MAC PDU comprises a first MAC header and a first MAC Service Data Unit (SDU). The first node monitors a first Hybrid Automatic Repeat reQuest Acknowledgment (HARQ-ACK) on each channel in a first channel set, and the first HARQ-ACK indicates whether the first MAC PDU is correctly decoded. The first physical-layer signaling comprises scheduling information of the first MAC PDU. The first channel set comprises Q channel(s), Q being a non-negative integer. The condition of whether a number of continuous HARQ DTXs reaches a first threshold is used to determine Q. The first MAC SDU is transmitted through a first radio bearer, and the first radio bearer is unrelated to whether the number of the continuous HARQ DTXs reaches the first threshold.

The present application provides a method and a device for sidelink relay wireless communications. A first node transmits first assistance information, the first assistance information indicating a transmission state of a first channel; and receives first configuration information, the first configuration information indicating a first time length; and receives a first MAC PDU, the first MAC PDU comprising a first MAC SDU; and selects a first time unit from a first time resource pool; and transmits a second MAC PDU in the first time unit; herein, the first assistance information is used for generating the first configuration information, and the second MAC PDU comprises at least partial bits in the first MAC SDU; the first channel connects the first node to a target receiver receiving the second MAC PDU. The present application addresses the delay coordination of relay transmission.

A node for wireless communications includes a transmitter for transmitting first signaling carrying a first source ID and a receiver for receiving a first signal on a target time-frequency resource block that is a time-frequency resource block in a target resource pool. The first source ID is used to identify another node, and the target resource pool includes a plurality of time-frequency resource blocks. In various embodiments, the first signaling indicates a first zone ID and/or a first candidate resource set that includes at least one time-frequency resource block. The first zone ID and/or a measurement corresponding to the first candidate resource set may be used to determine whether the first candidate resource set is within the target resource pool.

A method and device used for discontinuous reception. A first node transmits a first signaling, the first signaling indicating a current parameter of a first timer, and monitors a target signal in a first time-resource set; when the target signal is detected in the first time-resource set and the first timer is in a stopped state, starts the first timer; when the first timer is in a running state, updates the first timer in each candidate slot; wherein the current parameter of the first timer is related to at least one of a state of the first timer or a value of the first timer. The present disclosure prevents misunderstanding of the first time-frequency resource pool, thus reducing power consumption and radio interference.

A method and a device in a User Equipment (UE) and a base station for wireless communication. The UE first receives a first radio signal and a second radio signal, and then transmits a third radio signal. The first radio signal is used for determining a first signature sequence, and a receiving timing of the second radio signal is used for determining a transmitting timing of the third radio signal. The first signature sequence is used for generating the third radio signal. The first radio signal and the second radio signal are associated with a first synchronization sequence and a second synchronization sequence respectively, and the first synchronization sequence is different from the second synchronization sequence. Through the designs of the first radio signal and the second radio signal, system performances and transmission efficiency are improved.

The present application discloses a method and a device for wireless communications, including detecting invalidation of a first bearer; the first bearer being associated with a first cell group; and as a response to the action of detecting invalidation of a first bearer, executing a first operation set, the first operation set being related to a type of the first bearer; and transmitting first information as a response to the action of detecting invalidation of a first bearer; the first information being used to indicate the invalidation of the first bearer; and transmitting a second message as a response to all conditions in a first condition set being satisfied; the second message indicating existence of available information. The present application helps network optimization by detecting invalidation of the first bearer and executing the first operation set, thus enhancing the communication reliability and avoiding interruption.

A method and a device used for DRX. A first node receives K radio signal, K being a positive integer greater than 1; and updates a first timer per candidate slot passed when a value of the first timer is unequal to a first expiration value; or stops a first timer when a value of the first timer is equal to a first expiration value; herein, physical-layer channels occupied by the K radio signals respectively comprise K PSSCHs, and the K radio signals respectively comprise K Destination ID fields, the K Destination ID fields respectively being indicated by K SCIs; active time of the first node comprises time while the first timer is running, the first timer being a DRX-related timer. The present application can avoid misunderstanding of the state of the first timer, thus reducing power consumption and air-interface interferences.
