Abstract: A method for controlling positioning integrity. A location management device receives a first message sent by a terminal device, where the first message includes a first parameter set. The first parameter set includes measurement information and/or error information relating to location information of the terminal device. The error information is related to the positioning integrity. The location management device obtains a first positioning result based on the first parameter set and/or positioning assistance data. The first positioning result includes location information and/or integrity information of the terminal device. The integrity information includes the error information and/or alarm information, and the alarm information includes a determining result obtained by comparing the first positioning result with a preset determining condition.

Abstract: Example cross-link interference (CLI) measurement configuration methods and apparatus are described. In one example method, a first network device receives, from a second network device, a first message that indicates information about a CLI measurement. The first network device configures the CLI measurement for a terminal device based on the first message.

Abstract: A communication method and apparatus, a storage medium, and a chip system relate to the field of communication technologies, to reduce a bit error and/or a packet loss. In this application, a terminal device receives configuration information from a network device, where the configuration information is used to configure a first carrier. The terminal device sends first information to the network device. The first information indicates to stop data transmission on the first carrier. The first information further indicates that the terminal device stops measurement on the first carrier. Therefore, the network device may determine that a reason for receiving no measurement result of the first carrier from the terminal device is that a first terminal device does not measure the first carrier, rather than another reason, and then the network device can activate a carrier more properly.

Abstract: This application discloses a cell measurement method and an apparatus, where the method includes: A first network device determines first indication information, where the first indication information indicates at least one candidate cell and a first cell set corresponding to a first candidate cell in the at least one candidate cell, and the first cell set includes at least one cell. The first network device sends the first indication information. A terminal device receives the first indication information. The terminal device measures a cell in the first cell set based on the first indication information. A serving cell of the terminal device is the first candidate cell. In this manner, a range of cells measured and evaluated by the terminal device is specified, and cell handover efficiency and a cell handover success rate are improved.

Abstract: Example communication methods and apparatus are described. One example method includes receiving a first message by a terminal device from an access network device, where the first message indicates the terminal device to be handed over to a target cell or to be redirected to a target frequency. If the handover to the target cell fails or the redirection to the target frequency fails, the terminal device searches for an acceptable cell or a suitable cell. According to some embodiments of this application, an emergency call delay can be reduced.

Abstract: This application relates to a measurement method, an apparatus, and a system. The method includes: A terminal device performs, based on a first measurement requirement, measurement for radio link connection quality monitoring; and if a trigger condition is met, the terminal device performs, based on a second measurement requirement, the measurement for radio link connection quality monitoring, where the second measurement requirement is obtained through relaxing based on the first measurement requirement. In this solution, the terminal device may determine whether the trigger condition is met. If the trigger condition is met, it indicates that a communication condition or a network environment of the terminal device is stable, or the terminal device has a low requirement for current communication quality. In this case, frequent measurement for radio link connection quality monitoring is equivalent to an unnecessary measurement process, and power consumption is high.

Abstract: Example communication methods and communication apparatus are described. In one example method, a terminal device obtains first information, where the first information is different from second information, the first information is used to determine a start time of a first timer in a first hyper system frame, and the second information is used to determine a start time of a first timer in a second hyper system frame. The terminal device determines, based on the first information and a first parameter, the start time of the first timer in the first hyper system frame, where the first parameter is drx-StartOffset, and the first timer is a discontinuous reception on-duration time.

Abstract: This disclosure describes a random access method, an apparatus, and a system, to resolve an RNTI conflict during random access of different types of terminal devices or different types of services. An example method includes: sending a random access preamble to a network device on a first random access channel occasion RO, where the first RO corresponds to a first device type and/or a first service type; and listening to physical downlink control information PDCCH scrambled by using a first radio network temporary identifier RNTI associated with the first RO. Calculation of the first RNTI is associated with the first device type and/or the first service type.
