Abstract: This application provides a configuration method and a communication apparatus, and relates to the communication field. In the method, a terminal device may send first information to an access network device, where the first information indicates to reduce a capability of the terminal device. The access network device may send a first configuration to the terminal device based on a first capability, where the first capability of the terminal device and corresponding to the first configuration is a reduced capability of the terminal device.

Abstract: A method includes: determining, by a terminal device, first assistance information, wherein the first assistance information is used to indicate a configuration parameter requested by the terminal device from a first network device; and sending, by the terminal device, the first assistance information to a second network device, wherein the second network device is used to send the first assistance information to the first network device.

Abstract: A communications method includes the terminal device receiving a first message from a network device, where the first message indicates a second cell, the second cell includes a first downlink carrier and a second uplink carrier, and a duplex mode of a band to which the first downlink carrier belongs is different from a duplex mode of a band to which the second uplink carrier belongs, and the terminal device accesses the second cell.

Abstract: A random access method and device. The method includes receiving, by user equipment, a radio resource control (RRC) connection reconfiguration message from a first network device, the RRC connection reconfiguration message indicating a primary serving cell of the second network device for a user equipment, an active uplink bandwidth part (BWP) in the primary serving cell, and an active downlink BWP in the primary serving cell, the RRC connection reconfiguration message includes an uplink BWP identifier indicating the active uplink BWP and a downlink BWP identifier indicating the active downlink BWP, the uplink BWP identifier corresponds to the active uplink BWP, the downlink BWP identifier corresponds to the active downlink BWP, and initiating, by the user equipment, a random access procedure to the second network device on the active uplink BWP and the active downlink BWP.

Abstract: A data transmission method comprising: after sending first data on a first resource, a first apparatus may monitor second data on a second resource associated with the first resource. In other words, because the second resource is associated with the first resource, the first apparatus directly monitors the second data on the second resource, so that power consumption caused by blind detection can be avoided, or power consumption caused by detection based on a DRX function can be avoided, thereby reducing power consumption of the first apparatus.

Abstract: A communication method includes receiving a paging message, wherein the paging message comprises a first identifier. The first identifier is useable to identify a paged first terminal device. A bit length of the first identifier is less than a bit length of a second identifier. The second identifier is a 5th generation-system-temporary subscriber identity (5G-S-TMSI) or a radio network temporary identity (I-RNTI). The communication method further includes determining, based on the first identifier, that the first terminal device is paged.

Abstract: A terminal device receives a first system information change indication on a WUR link, and/or determines, on the WUR link, that a cell is changed, where the first system information change indication indicates that system information is changed. The terminal device receives the system information on an NR link if the system information is changed, before establishing or restoring a connection on the NR link. If the terminal device determines that the system information is not changed, the terminal device may not need to receive the system information. For example, the terminal device may directly establish or restore the connection on the NR link when the terminal device does not need to receive the system information.

Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

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.
