摘要： This application provides a method for monitoring a physical downlink control channel and a communications apparatus. The method includes: receiving, by a terminal device, a first message sent by a network device, where the first message includes M sleep time sets, and the sleep time is used to indicate a time length in which monitoring the PDCCH is stopped; receiving, by the terminal device, a second message sent by the network device, where the second message includes sleep time indication information, the sleep time indication information is used to indicate a target sleep time index, and the target sleep time index is an index in the M sleep time sets; and stopping, by the terminal device, monitoring the PDCCH in a target time period. Based on the foregoing technical solution, the terminal device can determine, based on the indication information sent by the network device, the time in which monitoring the PDCCH is stopped. In this way, the terminal device can monitor the PDCCH more flexibly.

摘要： This application relates to a communication method and a device. An access network device receives a first cycle from a core network device, where the first cycle is a maximum eDRX cycle that can be configured for a first terminal device, and the first cycle is used by the first terminal device in RRC inactive state. The access network device determines a second cycle based on the first cycle, where the second cycle is an eDRX cycle configured for the first terminal device, the second cycle is used by the first terminal device in RRC inactive state, and a length of the second cycle is less than or equal to a length of the first cycle. The access network device sends a second message to the core network device, where the second message includes the second cycle. The second cycle determined by the access network device based on the first cycle meets a requirement of the core network device, the core network device sends a NAS message according to the second cycle, and the first terminal device can properly receive the NAS message according to the second cycle. This increases a probability of the reception of the NAS message by the terminal device.

摘要： This application provides a timer processing method and a terminal device. The 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 and deactivate the active BWP pair. This resolves a prior-art problem that the default downlink BWP cannot be correctly switched to during timer start or restart, thereby reducing power consumption of the terminal device.

摘要： This specification provides a resource determining method and an apparatus, to optimize sidelink transmission performance. In this specification, a first communication apparatus may receive preferred resource information and/or non-preferred resource information, determine a transmission resource based on received resource information and a type of the first communication apparatus, and perform sidelink transmission by using the transmission resource. First resource information can indicate a high-interference or high-usage resource and/or a low-interference or low-usage resource. The first communication apparatus can select, based on the type of the first communication apparatus, a resource with relatively low interference to perform sidelink transmission. This improves sidelink transmission performance.

摘要： A measurement configuration method and an apparatus are provided. The method includes: A network device sends first information to a terminal device. The first information includes configuration information of an SCC. The network device sends second information to the terminal device. The second information includes configuration information of a first measurement window, and the second information is used to enable the terminal device to switch, when supporting CA, from performing cell measurement in a measurement window-free measurement manner to performing cell measurement by using the first measurement window. A carrier included in the CA includes the SCC configured based on the first information. According to the foregoing method, after the network device configures the SCC, the terminal device may switch, based on the second information, from performing cell measurement in the measurement window-free measurement manner to performing cell measurement by using the first measurement window. This can resolve a problem that a measurement capability of measurement-free window measurement is affected after the SCC is activated.

摘要： This specification provides a resource determining method and an apparatus, to optimize sidelink transmission performance. In this specification, a terminal device may obtain resource information, and determine a first resource jointly reserved by N services, where N is greater than or equal to 2. Whether to use the first resource jointly reserved by the N services as a candidate resource is properly determined based on signal strength thresholds of the N services and signal strength of the N services. Therefore, a transmission resource determining manner is optimized, and sidelink transmission performance can be improved.

摘要： Embodiments of this application relate to the communications field, and provide a signal monitoring method and an apparatus, to determine whether an occasion for monitoring a power saving signal is in an active time, so as to determine whether a terminal device needs to monitor the power saving signal at a corresponding occasion. The method is as follows: If the terminal device determines, based on a message received or sent in a first time unit, that the terminal device is not in a DRX active time in a second time unit, the terminal device monitors the power saving signal in the second time unit. The terminal device determines, based on the power saving signal, whether to monitor a PDCCH in a first time interval. The first time unit is located before the second time unit, and is separated from the second time unit by M third time units. M is an integer greater than or equal to 1. The embodiments of this application are applied to a mobile communications system such as 5G NR.
