Abstract: This application provides a method for determining a time of applying media access control MAC signaling and an apparatus, and relates to the field of communication technologies, to determine the time of applying the MAC signaling when DCI indicates that a terminal device delays feedback of a HARQ-ACK. In the method, the terminal device receives the MAC signaling. The terminal device receives first indication information, where the first indication information includes a first value for the terminal device to send the HARQ-ACK. The first value indicates whether the terminal device delays feedback of the HARQ-ACK. The terminal device determines the time of applying the MAC signaling. Based on the method, understandings of a network device and the terminal device on the time of applying the MAC signaling can be aligned, thereby improving communication performance.

Abstract: A beam information reporting and receiving method and apparatus are disclosed. The method at least includes: A terminal device receives first activation signaling from a network device, where the first activation signaling is used to activate a first cell, and the first cell is a secondary cell that has a capability of sending a physical uplink control channel PUCCH. The terminal device measures a reference signal of the first cell to determine beam information of the first cell. The terminal device sends layer 2 signaling to the network device by using a second cell, where the layer 2 signaling includes the beam information of the first cell, and the second cell is a primary cell or a primary secondary cell corresponding to the first cell.

Abstract: This application relates to a communication method and apparatus. An activation command is received from a network device, where the activation command indicates to activate a first secondary carrier, and the first secondary carrier is one of secondary carriers of a terminal device. When the first secondary carrier is known, whether to adjust AGC of the first secondary carrier is determined based on a measurement cycle of the terminal device for the first secondary carrier, where a temporary reference signal is used to adjust the AGC of the first secondary carrier. A first temporary reference signal is received from the first secondary carrier, and time-frequency synchronization with the first secondary carrier is performed based on the first temporary reference signal.

Abstract: This application provides example measurement methods and related example apparatuses. One example measurement method includes determining, by a terminal device and to generate a determining result, whether a measurement gap is involved when each of one or more measurement objects is measured in a first bandwidth part (BWP) group, where the first BWP group includes an active BWP of one or more serving cells of the terminal device. The terminal device can perform measurement-gap-based measurement or non-measurement-gap-based measurement based on the determination.

Abstract: A terminal determines whether a measurement gap type corresponding to a first group of MOs is an MG or an NCSG, measures the first group of MOs based on the measurement gap type corresponding to the first group of MOs, and determines a data transmission behavior in a serving cell of the terminal based on the measurement gap type corresponding to the first group of MOs.

Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus, to determine a measurement periodicity in which a communication device performs layer 1 signal to interference plus noise ratio (L1-SINR) beam measurement based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The method includes: A communication device receives a CMR and an IMR corresponding to the CMR. A terminal measures an L1-SINR of a receive beam based on the CMR and the IMR, to determine an optimal receive beam of the terminal. The CMR and the IMR are channel state information reference signal (CSI-RS) resources in different CSI-RS resource sets. The communication device determines a value of a first parameter based on repetition corresponding to a CSI-RS resource set corresponding to the CMR, and determines, based on the value of the first parameter, a measurement periodicity for measuring the L1-SINR.
