Abstract: This application provides a paging method and a communications apparatus. In the method, a first access network device may determine, based on grouping capability information of a first terminal device and a grouping manner supported by the first access network device for use, a first manner for paging the first terminal device. When determining the first manner, the first access network device considers the grouping capability information of the first terminal device. In this way, the determined first manner is a grouping manner supported by the first terminal device.

Abstract: A timer processing method includes: receiving, by a terminal device, a first message sent by a network device, and starting or restarting a timer based on a scrambling identifier of the first message, wherein the timer is a timer used by the terminal device to switch from an active downlink BWP to a default downlink BWP, or is a timer used by the terminal device to activate a default downlink BWP and deactivate an active downlink BWP; or if an active BWP pair of the terminal device is not a default BWP pair, starting or restarting, by the terminal device, a timer based on a scrambling identifier of the first message, wherein the timer is a timer used by the terminal device to switch from the active BWP pair to the default BWP pair, or is a timer used by the terminal device to activate the default BWP pair.

Abstract: Embodiments of this application provide a scheduling request processing method and a terminal device. The scheduling request processing method includes: determining that a regular buffer status report, BSR, associated with a first logical channel is triggered and has not been canceled; determining that there is no uplink resource available to transmit data of the first logical channel, and a first timer of a terminal device is not running; and triggering a scheduling request, SR, wherein the first timer is configured to delay transmission of the SR.

Abstract: A data processing method, a terminal device, and a base station are disclosed. The method includes: determining to change a type of at least one radio bearer of the terminal device from a first type to a second type; discarding a radio link control protocol RLC protocol data unit and/or an RLC service data unit buffered by a transmit side of an RLC layer entity of the at least one radio bearer; and assembling an RLC protocol data unit received by a receive side of the RLC layer entity of the at least one radio bearer into an RLC service data unit, and delivering the RLC service data unit in sequence to an upper layer entity of the RLC layer entity, where the upper layer entity is an upper layer entity of the RLC layer entity before the type of the at least one radio bearer is changed.

Abstract: An indication method, including receiving, by first user equipment, a first message sent by second user equipment, where the first message includes information indicating that the second user equipment supports an evolved user equipment-to-network relay function, and receiving, by the first user equipment, a second message sent by a network device, where the second message includes information indicating that the network device supports an evolved user equipment-to-network relay, or the second message includes information indicating that a cell in which the network device sends the second message supports an evolved user equipment-to-network relay.

Abstract: Methods are provided for ascertaining and measuring RPTP-? activity in response to insults such as UV irradiation and with respect to administration of a treatment and/or composition. Attenuation of EGFR activity by RPTP-? affects aspects of photoaging, including damage to the skin, suppression of the immune system, DNA damage, and connective tissue degradation. Intervention with respect to the effects of photoaging can include protection of RPTP-? from oxidation. The methods can be used for discovery of anti-aging treatments, adjuncts, or other preventative treatments, such as sunscreens.
