Abstract: This application discloses a path switching method that includes: sending, by a first terminal, a first message to a first network device, where the first message is used to request to switch a second terminal from an indirect connection path for communicating with the first network device by using the first terminal to a direct connection path for communicating with the first network device or a second network device, or the first message is used to request to release a link between the first terminal and the second terminal, and the first network device is different from the second network device; and releasing, by the first terminal, the link between the first terminal and the second terminal. With this solution, a relay terminal can trigger switching of a remote terminal from an indirect connection path to a direct connection path, to adapt to a relay scenario more flexibly.

Abstract: A scheduling switching method includes receiving, by a terminal, a switching indication from a network device, where the switching indication indicates the terminal to switch from a first scheduling mode to a second scheduling mode. The method further includes determining an application time of the second scheduling mode such that the terminal schedules a data channel or triggers a reference signal using the second scheduling mode when the application time arrives.

Abstract: This application provides a pending SR cancellation method and an apparatus. In the method, when a specific condition is met, a terminal cancels a pending SR triggered by an uplink BSR, and when some other conditions are met, the terminal cancels a pending SR triggered by a sidelink BSR. In other words, the terminal may independently cancel the SR triggered by the uplink BSR and the SR triggered by the sidelink BSR. When canceling the SR triggered by the uplink BSR, the terminal may not cancel the SR triggered by the sidelink BSR, so that when sidelink data has a relatively high latency requirement.

Abstract: A timer control method includes a receiving device that performs re-establishment or data recovery on a Packet Data Convergence Protocol (PDCP) layer of the receiving device. The PDCP layer stops the running of a reordering timer of the PDCP layer when the reordering timer is in a running state, where the reordering timer enables the PDCP layer to wait to receive a lost data packet. Because the reordering timer is stopped from running rather than expires, the PDCP layer does not update a value of RX_DELIV.

Abstract: When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and a PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity.

Abstract: A path switching method and a related device, where the method includes receiving, by a base station, a first message from a first user equipment requesting to switch the first user equipment from a non-direct path for communicating with the base station using a second user equipment to a direct path communicating with the base station, and sending, by the base station, a second message to the first user equipment instructing the first user equipment to perform path switching. The second message includes at least one of a timing advance, a closed-loop power control value or an uplink grant configuration.

Abstract: Embodiments provide a data transmission method and a related device. Under the method, after determining a first data packet to be sent to a receive end, a transmit end may generate a second data packet based on the first data packet, encode the second data packet, and send an encoded second data packet. A length of the second data packet is greater than a length of the first data packet. In various embodiments, when sending a data packet to the receive end, the transmit end may generate a longer data packet from a shorter data packet through combination, and send the longer data packet to the receive end after channel coding. In this way, a relatively high channel coding gain can be obtained during data transmission, and a relatively high bit error rate of short packet transmission is avoided, so that data transmission reliability can be improved.
