Abstract: Embodiments of the present invention provide an uplink subcarrier spacing indication method, a base station, and a terminal. The base station determines indication information that is used to indicate a first uplink subcarrier spacing supported by the base station, and communicates with the terminal according to the indication information. During the communication, the base station indicates the first uplink subcarrier spacing supported by the base station to the terminal, so that the terminal subsequently determines, based on the first uplink subcarrier spacing, a second uplink subcarrier spacing supported by the terminal; or the base station receives information that is sent by the terminal and that carries a second uplink subcarrier spacing, in other words, receives an indication from the terminal, so as to learn of the second uplink subcarrier spacing supported by the terminal or to be used by the terminal to send an uplink signal.

Abstract: A resource selection method includes monitoring, by a first terminal, a first subframe, where a quantity of the first subframes is less than or equal to a quantity of second subframes; receiving, by the first terminal, indication information in the first subframe determining, by the first terminal, a first resource in the second subframe according to the indication information; and selecting, according to the first resource, a resource in the second subframe for the first terminal to send data. There may be one or more first subframes; the second subframe may be a candidate subframe, and there may be one or more candidate subframes. The indication information includes information that can indicate a resource reserved by a second terminal, that is, indication information that can indicate a resource excluded by the second terminal.

Abstract: An optical switch chip, an optical switch driving module, and an optical switch driving method are disclosed. The optical switch driving module includes an optical switch chip, and the optical switch chip includes multiple optical switch units. The optical switch units are divided into N groups, where N>=1. Each group of optical switch units shares a pair of electrodes, each pair of electrodes is configured to connect to a multi-frequency driving signal source, and each optical switch unit connects to the multi-frequency driving signal source by using the band-pass filter. Pass bands of M band-pass filters that are connected to M optical switch units in a same group are different, where M>=2. The multi-frequency driving signal source outputs multiple driving signals of different frequencies that are respectively corresponding to the M band-pass filters, so as to drive the optical switch unit.

Abstract: This application relates to a communication method and device. A remote terminal device receives a first data packet from a relay terminal device by using an SRB1. The first data packet includes a first message and an SRAP header. The remote terminal device removes the SRAP header via an SRAP entity to obtain configuration information. The SRAP entity is determined before the SRAP header is removed. The remote terminal device configures the SRAP entity based on the configuration information. The remote terminal device may predetermine the SRAP entity.

Abstract: An access network device determines to add, for a remote terminal device, a direct path for connecting a first cell. The remote terminal device is connected to a second cell through an indirect path. The access network device sends an RRC reconfiguration message to indicate the remote terminal device to switch to the direct path. The RRC reconfiguration message further indicate not to release the indirect path. When being indicated to switch to the direct path, the remote terminal device may further be indicated not to release the indirect path.

Abstract: A communication method and a communication apparatus are provided. The method includes: A first terminal device sends data to a second terminal device over a plurality of carriers through a sidelink SL. The first terminal device determines feedback reception situations for the data on feedback reception occasions over the plurality of carriers, where the feedback reception occasion is a feedback reception occasion for the data. The first terminal device determines, based on the feedback reception situations, whether an SL radio link failure RLF occurs between the first terminal device and the second terminal device. According to this application, the SL RLF can be processed when transmission with one PC5-RRC connection is performed over the plurality of carriers.

Abstract: This application relates to a communication method and device. A first terminal device receives at least one message for reserving a resource, and the first terminal device determines, from S resources based on the at least one message, M resources whose signal strengths do not meet a first signal strength threshold. The first terminal device adjusts the first signal strength threshold if M does not meet a first resource quantity or S-M does not meet a first resource quantity. The first terminal device sends a first message to a second terminal device, where the first message indicates a resource determined based on an adjusted signal strength threshold, and the adjusted signal strength threshold enables M or S-M to meet the first resource quantity.
