Terminal equipment can also be simply referred to as terminal or UE, the meaning of which can be understood by those skilled in the art.
[0044] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between terminal device 10 and core network element 30 through access network device 20. For example, in an LTE (Long Term Evolution) system, access network device 20 may be one or more eNodeBs in an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or EUTRAN; in a 5G NR system, access network device 20 may be one or more gNBs in a RAN (Radio Access Network). In the embodiments of this application, unless otherwise specified, the term "network device" refers to access network device 20, such as a base station.
[0045] Core network element 30 is a network element deployed in the core network.

The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.
[0049] The following sections describe the background of network energy saving, the initial access process in the NR system, and the configuration of cell DTX (Discontinuous Transmission) and / or cell DRX (Discontinuous Reception) in the NR system. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.
[0050] 1. Background of Network Energy Conservation
[0051] Network energy saving (NES) is of great significance for environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. Energy consumption has become a key part of operators' operating expenditure (OPEX). According to a report by the GSMA (Global System for Mobile Communications Association), energy costs of mobile networks account for approximately 23% of total operating costs. Most energy consumption comes from the radio access network, more specifically from the active antenna unit (AAU), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being transmitted or received; the static part includes the power consumption at all times necessary for the operation of the radio access equipment, including power consumption when no data is being transmitted or received.
[0052] With the development of communication technology and the evolution of communication systems, energy consumption has gradually become an important KPI (Key Performance Indicator) for the operating efficiency of communication systems. Therefore, when designing 6G communication systems, network energy-saving technologies need to be considered from the very first version.
[0053] 2. Initial Access Procedure in NR System
[0054] In NR systems, the initial access process for terminal devices can be completed by detecting synchronization signal blocks (SSBs or SS / PBCH blocks) on the GSCN (Global Synchronization Channel Number) (also known as the Sync Raster). During the initial access process, the terminal device determines the possible time-frequency locations of SSBs using a predefined set of GSCNs, attempts to search for SSBs, and obtains time and frequency synchronization, radio frame timing, and cell IDs (identifiers) through the detected SSBs.
[0055] After detecting an SSB, the terminal device can determine the configuration of the Type0-PDCCH (Physical Downlink Control Channel) CSS (Common Search Space) set through the MIB (Master Information Block) message in the SSB. The terminal device can receive the network device's scheduling of SIB1 (System Information Block) messages by listening to the Type0-PDCCH CSS set. Both the MIB and SIB1 messages include the serving cell's system configuration information. Furthermore, the terminal device can receive the network device's scheduling of other system messages besides SIB1 messages by listening to the Type0A-PDCCH CSS set, receive the network device's scheduling of paging messages by listening to the Type2-PDCCH CSS set, and receive the Paging Early Indication (PEI) information for paging messages sent by the network device by listening to the Type2A-PDCCH CSS set.
[0056] The terminal device can also obtain the resource configuration of PRACH (Physical Random Access Channel) transmission opportunities (RO) during random access based on the received cell system message SIB1. According to the RO resources configured by the network device, the terminal device can initiate random access to the network device or request the transmission of system messages. The system messages that the terminal device requests to be sent to the network device can be other system messages besides SIB1.
[0057] 3. Cell DTX and / or cell DRX configuration in the NR system
[0058] In NR systems, to achieve network energy saving, network devices can configure cell DTX and / or cell DRX for terminal devices. Cell DTX and / or cell DRX are primarily configured for terminal devices in connected mode. Cell DTX and / or cell DRX can be considered as cell-common DTX and / or DRX. Cell DTX can refer to discontinuous transmission by network devices in the cell. Cell DRX can refer to discontinuous reception by network devices in the cell.
[0059] During the inactive period of the cell DTX configured for the terminal device, the terminal device does not expect to receive the following downlink channels or signals (e.g., the network device may not send the following downlink channels or signals): periodic or semi-persistent CSI-RS (Channel State Information-Reference Signal) associated with CSI (Channel State Information) reporting, PDCCH with UE-specific RNTI (Radio Network Temporary Identifier) scrambling, SPS-PDSCH (Semi-Persistent Scheduling-Physical Downlink Shared Channel), and PDCCH associated with DCI (Downlink Control Information) formats 2_0 to 2_5. During the inactive period of the cell DRX configured for the terminal device, the terminal device does not expect to send the following uplink channels or signals (e.g., network devices may not receive the following uplink channels or signals): SR (Scheduling Request), periodic or semi-persistent CSI reporting, periodic or semi-persistent SRS (Sounding Reference Signal) (excluding SRS used for positioning), and CG-PUSCH (Configured Grant-Physical Uplink Shared Channel). This method enables energy savings for network devices.
[0060] Network devices can be configured with cell DTX and cell DRX independently, or simultaneously. The configuration of cell DTX and / or cell DRX can be activated or deactivated via RRC (Radio Resource Control) signaling or DCI signaling.
[0061] With the development of communication technology, research on 6G communication technology has begun. Considering the importance of network energy conservation, possible energy-saving solutions need to be considered from the initial design stage of 6G communication technology. From the perspective of network energy conservation, to achieve network energy saving, network equipment should minimize the transmission of "always-on" signals (such as SSB, SIB, Paging, and other common channels or signals) to avoid potentially meaningless energy consumption. From the perspective of terminal device communication performance, terminal devices need to receive a sufficient number of signal samples to achieve the required communication performance through methods such as combining. This requires network equipment to allocate sufficient resources to transmit "always-on" signals. In future 6G systems, how to optimize system design to achieve a good trade-off between the energy-saving performance of network equipment and the communication performance of terminal devices remains a problem to be solved.
[0062] In existing NR systems, cell DTX and / or cell DRX are configured for NES-enabled terminal devices in connected mode. This is mainly because traditional terminal devices cannot recognize the NES configuration of a cell. If the transmission of common channels or signals in an NES cell is also affected by the cell DTX and / or cell DRX configuration, it may cause traditional terminal devices to incorrectly receive common channels or signals in the NES cell, resulting in reduced performance when accessing the NES cell. However, the 6G system is a completely new system. If cell DTX and / or cell DRX configuration is introduced from the first version, there will be no backward compatibility issues. Network devices and terminal devices can refrain from communicating with "always-on" signals during the off-duration (also known as the non-activation period) of cell DTX and / or cell DRX, saving energy consumption for both network and terminal devices. Furthermore, to enhance the communication performance of terminal devices receiving "always-on" signals, the transmission density of "always-on" signals can be increased during the on-duration (also known as the activation period) of cell DTX and / or cell DRX. Based on the above considerations, this application proposes the following technical solution.
[0063] Please refer to Figure 2, which shows a flowchart of a wireless communication method provided in one embodiment of this application. This method can be applied to the network architecture shown in Figure 1. The method may include the following step 210.

If the first indication information is configured, the cell DTX configuration of the first cell is effective; and / or, if the first indication information is not configured, the cell DTX configuration of the first cell is invalid.
[0092] In some embodiments, whether the cell DRX configuration of the first cell is an effective configuration is determined based on one of the following:
[0093] (1) When the first configuration information is used to configure the cell DRX of the first cell, the configuration of the cell DRX of the first cell is effective;
[0094] (2) When the first configuration information is used to configure the cell DRX of the first cell and the configuration of the cell DRX of the first cell is in an active state, the configuration of the cell DRX of the first cell is an effective configuration;
[0095] (3) If the first configuration information is used to configure the cell DRX of the first cell, determine whether the configuration of the cell DRX of the first cell is effective according to the second indication information;
[0096] (4) If the first configuration information is used to configure the cell DRX of the first cell and the configuration of the cell DRX of the first cell is inactive, determine whether the configuration of the cell DRX of the first cell is effective according to the second instruction information.
[0097] The second indication information is used to determine whether the cell DRX configuration of the first cell is an effective configuration.
[0098] In the above situation (1), if the first configuration information configures the cell DRX of the first cell, it means that the configuration of the cell DRX of the first cell is effective; otherwise, if the first configuration information does not configure the cell DRX of the first cell, it means that there is no configuration of the cell DRX of the first cell, or the configuration of the cell DRX of the first cell is not effective.
[0099] In the above situation (2), if the first configuration information configures the cell DRX of the first cell, and the cell DRX of the first cell is determined to be in an active state based on the first configuration information, then the configuration of the cell DRX of the first cell is effective; otherwise, if the first configuration information configures the cell DRX of the first cell, and the cell DRX of the first cell is determined to be in an inactive state based on the first configuration information, then the configuration of the cell DRX of the first cell is invalid; or, if the first configuration information does not configure the cell DRX of the first cell, then there is no configuration of the cell DRX of the first cell, or the configuration of the cell DRX of the first cell is not effective.
[0100] For the above situations (3) or (4), determine whether the configuration of the cell DRX of the first cell is effective by combining the second instruction information.
[0101] For example, the second indication information is used to indicate whether to activate or deactivate the cell DRX configuration of the first cell. When the second indication information indicates that the cell DRX configuration of the first cell is activated, the cell DRX configuration of the first cell is an active configuration; and / or, when the second indication information indicates that the cell DRX configuration of the first cell is deactivated, the cell DRX configuration of the first cell is an invalid configuration.
[0102] For example, the effectiveness of the cell DRX configuration of the first cell is determined based on whether the second indication information is configured. If the second indication information is configured, the cell DRX configuration of the first cell is effective; and / or, if the second indication information is not configured, the cell DRX configuration of the first cell is invalid.
[0103] In some embodiments, the first indication information is carried in at least one of the following: PDCCH, PDSCH, SSB, DL RS; and / or, the second indication information is carried in at least one of the following: PDCCH, PDSCH, SSB, DL RS.
[0104] In some embodiments, the first indication information and the second indication information are the same information. That is, the indication information is used to determine whether the configuration of the cell DTX and / or cell DRX of the first cell is an effective configuration. For example, when the first configuration information is used to configure the cell DTX of the first cell but the cell DRX of the first cell is not configured, the indication information is used to determine whether the configuration of the cell DTX of the first cell is an effective configuration. For example, when the first configuration information is used to configure the cell DRX of the first cell but the cell DTX of the first cell is not configured, the indication information is used to determine whether the configuration of the cell DRX of the first cell is an effective configuration. For example, when the first configuration information is used to configure both the cell DTX and cell DRX of the first cell, the indication information is used to determine whether the configurations of both the cell DTX and cell DRX of the first cell are effective configurations or both are invalid configurations.
[0105] In some embodiments, the first indication information and the second indication information are two independent information. That is, the first indication information is specifically used to determine whether the cell DTX configuration of the first cell is effective, and the second indication information is specifically used to determine whether the cell DRX configuration of the first cell is effective.
[0106] In some embodiments, the first indication information and the second indication information are carried in the same message. Exemplarily, the first indication information and the second indication information are two independent pieces of information, and these two independent pieces of information can be carried in the same message. In some embodiments, the first indication information and the second indication information can also be carried in two different messages. Optionally, the above message includes at least one of the following: SIB, RRC signaling, DCI, MAC CE (Media Access Control Control Element), and paging message indication.
[0107] In some embodiments, the first indication information and the second indication information are transmitted through the same channel or signal. Exemplarily, the first indication information and the second indication information are two independent pieces of information, and these two independent pieces of information can be transmitted through the same channel or signal. In some embodiments, the first indication information and the second indication information can also be transmitted through two different channels or signals. Optionally, the aforementioned channel or signal includes at least one of the following: PDCCH, PDSCH, SSB, and DL RS.
[0108] In some embodiments, the first configuration information is carried in at least one of the following: SIB, RRC signaling, MAC CE, paging message indication, and DCI. In some embodiments, the first configuration information includes one or more configuration information. For example, the first configuration information includes two configuration information, which are used to configure the cell DTX and cell DRX of the first cell, respectively.
[0109] In some embodiments, the frequency domain resources corresponding to the cell DTX of the first cell are the downlink frequency domain resources of the first cell. For example, the frequency domain resources corresponding to the cell DTX of the first cell are the frequency domain resources corresponding to the downlink carrier bandwidth of the first cell.
[0110] In some embodiments, the frequency domain resources corresponding to the cell DRX of the first cell are the uplink frequency domain resources of the first cell. For example, the frequency domain resources corresponding to the cell DRX of the first cell are the frequency domain resources corresponding to the uplink carrier bandwidth of the first cell.
[0111] In some embodiments, the first configuration information is used to configure the cell DTX and / or cell DRX of the first cell. The first configuration information is also used to configure the downlink frequency domain resources corresponding to the cell DTX of the first cell, and / or the uplink frequency domain resources corresponding to the cell DRX of the first cell.
[0112] In some embodiments, in an FDD (Frequency Division Duplexing) scenario, the downlink frequency domain resources corresponding to the cell DTX of the first cell and the uplink frequency domain resources corresponding to the cell DRX of the first cell are different. For example, the first configuration information is also used to configure the cell DTX of the first cell to correspond to the first downlink BWP (Bandwidth Part), and / or, the cell DRX of the first cell to correspond to the first uplink BWP, wherein the first downlink BWP and the first uplink BWP are two different BWPs.
[0113] In some embodiments, in a TDD (Time Division Duplexing) scenario, the downlink frequency domain resources corresponding to the cell DTX of the first cell and the uplink frequency domain resources corresponding to the cell DRX of the first cell can be the same or different. For example, the first configuration information is further used to configure the cell DTX of the first cell to correspond to a first BWP, and / or, the cell DRX of the first cell to correspond to a first BWP. As another example, the first configuration information is further used to configure the cell DTX of the first cell to correspond to a first BWP, and / or, the cell DRX of the first cell to correspond to a second BWP, wherein the first BWP and the second BWP are two different BWPs.
[0114] In some embodiments, BWP can be replaced by frequency domain resources corresponding to the transmission bandwidth.
[0115] The technical solution provided in this application provides that by configuring a first downlink resource in periodic downlink resources for transmitting a first downlink channel or signal, and / or configuring a first uplink resource in periodic uplink resources for transmitting a first uplink channel or signal, such as configuring cell DTX for downlink common channels or signals, and / or configuring cell DRX for uplink contention resources, this helps to save energy consumption of network equipment and terminal equipment.
[0116] Furthermore, the following beneficial effects can also be obtained:
[0117] 1) Allows network devices to stop transmitting signals for a period of time. When network devices in multiple cells use cell DTX technology on the same frequency band, it can effectively reduce unnecessary signal transmission in the air, reduce inter-cell interference, improve the accuracy and stability of data transmission, reduce the bit error rate, improve the utilization efficiency of spectrum resources, and thus improve the communication quality of the entire network.
[0118] 2) It can effectively reduce the energy consumption of network equipment and lower operating costs without affecting the quality of communication services, which is more in line with the development concept of green communication.
[0119] 3) During sleep mode, terminal devices reduce their listening to the downlink control channel, thereby reducing signaling interactions with network devices, which reduces signaling overhead and saves power consumption of terminal devices.
[0120] 4) Although frequent switching of the transmitter on and off will cause some losses, compared with continuous transmission, turning off the transmitter when there is no data transmission can reduce the transmitter's heat generation and the aging of electronic components, extend the service life of network equipment and terminal equipment, and reduce the frequency of equipment maintenance and replacement.
[0121] 5) By selecting and adjusting the period and parameters of cell DTX and / or cell DRX, the network can better cope with different service traffic demands and achieve the optimal solution to meet network communication quality and network energy saving requirements.
[0122] The following describes how to determine the first downlink resource when the first configuration information is used to configure the cell DTX of the first cell.
[0123] In some embodiments, the terminal device determines the first downlink resource in the first cell for transmitting the first downlink channel or signal based on the cell DTX of the first cell, including: when the cell DTX of the first cell is configured to be active, the terminal device determines the first downlink resource in the first cell for transmitting the first downlink channel or signal based on the cell DTX of the first cell.
[0124] For example, when the cell DTX configuration of the first cell is active, the terminal device determines the first downlink resource in the first cell for transmitting the first downlink channel or signal according to the activation period of the cell DTX of the first cell.
[0125] In some embodiments, the first configuration information is used to configure the cell DTX of the first cell, and the first downlink resources are determined based on the second configuration information and the cell DTX of the first cell.
[0126] In some embodiments, the first configuration information is used to configure the cell DTX of the first cell. When the cell DTX of the first cell is configured as an effective configuration, the first downlink resources are determined according to the second configuration information and the cell DTX of the first cell.
[0127] For details on how to determine whether the cell DTX configuration of the first cell is effective, please refer to the description in the above embodiments.
[0128] The terminal device determines the first downlink resource in the first cell for transmitting the first downlink channel or signal based on the second configuration information and the cell DTX of the first cell, including the following case 1 or case 2.
[0129] Case 1: The second configuration information is used to determine or configure a periodic first downlink resource. Specifically, the first downlink resource is valid during the active period of the cell DTX of the first cell, and / or invalid during the inactive period of the cell DTX of the first cell. A specific example of Case 1 can be found in Example 1 below.
[0130] Case 2: The second configuration information is used to determine or configure the first downlink resources during the activation period of the cell DTX of the first cell. For a specific example of Case 2, please refer to Example 2 below.
[0131] In some embodiments, the second configuration information is used to determine at least one of the following: the length of the period of the first downlink resource, the starting position of the period of the first downlink resource, the position of the starting position of the first downlink resource within the period of the first downlink resource, the frequency domain resource position corresponding to the first downlink resource, the position of the starting position of the first downlink resource within the activation period of the cell DTX of the first cell, the offset between the starting position of the first downlink resource and the starting position of the activation period of the cell DTX of the first cell, the offset between the starting position of the first downlink resource and the starting position of the period of the cell DTX of the first cell, and the time domain resource length corresponding to the first downlink resource.
[0132] Optionally, the above starting position includes the starting position in the time domain.
[0133] Optionally, when the starting position of the first downlink resource is the same as the starting position of the activation period of the cell DTX of the first cell, it can be considered that the offset between the starting position of the first downlink resource and the starting position of the activation period of the cell DTX of the first cell is 0, or there is no offset.
[0134] Optionally, when the starting position of the first downlink resource is the same as the starting position of the cell DTX period of the first cell, it can be considered that the offset between the starting position of the first downlink resource and the starting position of the cell DTX period of the first cell is 0, or there is no offset.
[0135] In some embodiments, the first downlink resource may include one downlink resource, or the first downlink resource may include N downlink resources, where N is an integer greater than 1. One downlink resource is used to transmit a first downlink channel or signal.
[0136] When the first downlink resource comprises N downlink resources, it can also be understood as the first downlink resource comprising a group of downlink resources, or the first downlink resource comprising a group of downlink resources, which in turn comprises N downlink resources. It is understood that if the first downlink resource comprises N downlink resources, more downlink resources can be used for the first downlink channel or signal transmission during the activation period of the cell DTX in the first cell. If these N downlink resources are used to repeatedly transmit the first downlink channel or signal, the performance of the terminal device in receiving the first downlink channel or signal can be improved. If these N downlink resources are candidate resources for transmitting the first downlink channel or signal, the transmission opportunities for the first downlink channel or signal can be increased, and the transmission latency of the first downlink channel or signal can be reduced. Both approaches can improve the communication performance of the terminal device.
[0137] For example, as shown in Figure 3, a schematic diagram of a first downlink resource comprising a downlink resource group is presented. In Figure 3, the length of the first time period is 1 ms, and the first downlink resource includes 4 downlink resources (N=4). The advantage of Figure 3 is that more downlink resources can be added during the activation period of the cell DTX of the first cell, thereby improving the communication performance of the terminal device.
[0138] In some embodiments, the aforementioned N downlink resources are used within a first time period. The first downlink resources include N downlink resources within the first time period, each of which is used to transmit a first downlink channel or signal. For example, the first downlink resources are used to transmit a first SSB transmission opportunity, which includes at most N candidate SSB indices, and each of the N downlink resources is used to transmit one SSB. Another example is that the first downlink resources are candidate resources for first PDCCH transmission, and each of the N downlink resources can be used to transmit the first PDCCH. Yet another example is that the first downlink resources are resources for first DL RS transmission, and each of the N downlink resources is used to transmit one first DL RS.
[0139] In some embodiments, the first downlink resource is determined based on at least one of the following: the length of a first time period, the number N of downlink resources included in the first time period, the number of symbols occupied by a downlink resource in the time domain, and the time domain interval between two adjacent downlink resources. Optionally, the above information is predefined, or the above information is configured by the network device, or some of the above information is predefined and some is configured by the network device. Optionally, the network device is configured using second configuration information.
[0140] For example, the first downlink channel or signal is an SSB, and the length of the first time period, the number N of downlink resources included in the first time period, the number of symbols occupied by a downlink resource in the time domain, and the time domain interval between two adjacent downlink resources are predefined.
[0141] For example, the first downlink channel or signal is PDCCH, and the length of the first time period, the number N of downlink resources included in the first time period, the number of symbols occupied by a downlink resource in the time domain, and the time domain interval between two adjacent downlink resources are configured by the network device.
[0142] For example, the first downlink channel or signal is DL RS, the length of the first time period and the number of symbols occupied by a downlink resource in the time domain are predefined, and the number N of downlink resources included in the first time period and the time domain interval between two adjacent downlink resources are configured by the network device.
[0143] In some embodiments, when the first downlink resource includes N downlink resources, the N downlink resources correspond to the same frequency domain resource location and size, and / or, the N downlink resources correspond to the same number of symbols.
[0144] In some embodiments, the time-domain resource length corresponding to the first downlink resource mentioned above refers to the number of symbols occupied by a downlink resource in the time domain, and / or the length of the first time period. For example, when the first downlink resource includes one downlink resource, the time-domain resource length corresponding to the first downlink resource mentioned above may refer to the number of symbols occupied by that one downlink resource in the time domain. For example, when the first downlink resource includes N downlink resources, the time-domain resource length corresponding to the first downlink resource mentioned above may refer to the length of the first time period in which the N downlink resources are located.
[0145] In some embodiments, the first configuration information is used to configure the cell DTX of the first cell. If at least a portion of the first downlink resources are located in the inactive period of the cell DTX of the first cell, and the first downlink resources include N downlink resources, where N is greater than 1, whether the first downlink resources are valid includes one of the following:
[0146] (1) All N downlink resources are invalid resources;
[0147] (2) All N downlink resources are valid resources;
[0148] (3) Among the N downlink resources, the downlink resources in the cell DTX of the first cell during the activation period are valid resources, and / or the downlink resources in the cell DTX of the first cell during the non-activation period are invalid resources.
[0149] (4) For each of the N downlink resources, the downlink resource is a valid resource if all its symbols are located within the active period of the cell DTX of the first cell; and / or, the downlink resource is an invalid resource if some or all of its symbols are located within the inactive period of the cell DTX of the first cell.
[0150] In some embodiments, the first configuration information is used to configure the cell DTX of the first cell. If at least a portion of the first downlink resources are located within the inactive period of the cell DTX of the first cell, and the first downlink resources include one downlink resource, whether the first downlink resource is valid includes one of the following:
[0151] (1) The first downlink resource is an invalid resource;
[0152] (2) The first downlink resource is a valid resource;
[0153] (3) Symbols in the first downlink resources that are located in the cell DTX of the first cell during the activation period are valid resources, and / or symbols in the first downlink resources that are located in the cell DTX of the first cell during the non-activation period are invalid resources.
[0154] Optionally, if the downlink resource is a valid resource, the downlink resource can be used to transmit the first downlink channel or signal, and the terminal device assumes that the network device has transmitted the first downlink channel or signal on the valid downlink resource; if the downlink resource is an invalid resource, the downlink resource cannot be used to transmit the first downlink channel or signal, and the terminal device assumes that the network device has not transmitted the first downlink channel or signal on the invalid downlink resource.
[0155] Optionally, the terminal device listens for or receives the first downlink channel or signal on valid resources, and does not listen for or receive the first downlink channel or signal on invalid resources.
[0156] Optionally, the method for determining whether the first downlink resource is valid is predefined or configured by the network device.
[0157] Using the above method, when the first configuration information is used to configure the cell DTX of the first cell, the terminal device and the network device can determine the first downlink resource in the same way and determine whether the first downlink resource is valid in the same way, thereby ensuring that the terminal device and the network device have a consistent understanding of the first downlink resource, which helps to improve the transmission performance of the first downlink channel or signal.
[0158] The following describes how to determine the first uplink resource when the first configuration information is used to configure the cell DRX of the first cell.
[0159] In some embodiments, the terminal device determines the first uplink resource in the first cell for transmitting the first uplink channel or signal based on the cell DRX of the first cell, including: when the cell DRX of the first cell is configured to be active, the terminal device determines the first uplink resource in the first cell for transmitting the first uplink channel or signal based on the cell DRX of the first cell.
[0160] For example, when the cell DRX configuration of the first cell is active, the terminal device determines the first uplink resource in the first cell for transmitting the first uplink channel or signal according to the activation period of the cell DRX of the first cell.
[0161] In some embodiments, the first configuration information is used to configure the cell DRX of the first cell, and the first uplink resource is determined based on the third configuration information and the cell DRX of the first cell.
[0162] In some embodiments, the first configuration information is used to configure the cell DRX of the first cell. When the configuration of the cell DRX of the first cell is active, the first uplink resource is determined according to the third configuration information and the cell DRX of the first cell.
[0163] For details on how to determine whether the cell DRX configuration of the first cell is effective, please refer to the description in the above embodiments.
[0164] The terminal device determines the first uplink resource in the first cell for transmitting the first uplink channel or signal based on the third configuration information and the cell DRX of the first cell, including the following case 1 or case 2.
[0165] Case 1: The third configuration information is used to determine or configure a periodic first uplink resource. Specifically, the first uplink resource is valid during the active period of the cell DRX of the first cell, and / or invalid during the inactive period of the cell DRX of the first cell. A specific example of Case 1 can be found in Example 1 below.
[0166] Scenario 2: The third configuration information is used to determine or configure the first uplink resource during the activation period of the cell DRX of the first cell. For a specific example of Scenario 2, please refer to Example 2 below.
[0167] In some embodiments, the third configuration information is used to determine at least one of the following: the length of the period of the first uplink resource, the start position of the period of the first uplink resource, the position of the start position of the first uplink resource within the period of the first uplink resource, the frequency domain resource position corresponding to the first uplink resource, the position of the start position of the first uplink resource within the activation period of the cell DRX of the first cell, the offset between the start position of the first uplink resource and the start position of the activation period of the cell DRX of the first cell, the offset between the start position of the first uplink resource and the start position of the period of the cell DRX of the first cell, and the time domain resource length corresponding to the first uplink resource.
[0168] Optionally, the above starting position includes the starting position in the time domain.
[0169] Optionally, when the starting position of the first uplink resource is the same as the starting position of the activation period of the cell DRX of the first cell, it can be considered that the offset between the starting position of the first uplink resource and the starting position of the activation period of the cell DRX of the first cell is 0, or there is no offset.
[0170] Optionally, when the starting position of the first uplink resource is the same as the starting position of the cell DRX period of the first cell, it can be considered that the offset between the starting position of the first uplink resource and the starting position of the cell DRX period of the first cell is 0, or there is no offset.
[0171] In some embodiments, the first uplink resource may include one uplink resource, or the first uplink resource may include M uplink resources, where M is an integer greater than 1. One uplink resource is used to transmit a first uplink channel or signal.
[0172] When the first uplink resource comprises M uplink resources, it can also be understood as the first uplink resource comprising a group of uplink resources, or the first uplink resource comprising a group of uplink resources, which in turn comprises M uplink resources. It is understood that if the first uplink resource comprises M uplink resources, then during the activation period of the cell DRX in the first cell, more uplink resources can be used for the first uplink channel or signal transmission. If these M uplink resources are used to repeatedly transmit the first uplink channel or signal, the performance of the network device in receiving the first uplink channel or signal can be improved. If these M uplink resources are candidate resources for transmitting the first uplink channel or signal, the transmission opportunities for the first uplink channel or signal can be increased, and the transmission latency of the first uplink channel or signal can be reduced. Both approaches can improve the communication performance of the terminal device.
[0173] In some embodiments, the aforementioned M uplink resources are used within a second time period. The first uplink resources include the M uplink resources within the second time period, each of the M uplink resources being used to transmit a first uplink channel or signal. For example, each of the M uplink resources is used to transmit a PRACH. Another example is that each of the M uplink resources is used to transmit a PRACH and a PUSCH. Yet another example is that each of the M uplink resources is used to transmit a PUSCH. Yet another example is that each of the M uplink resources is used to transmit a PUCCH. Yet another example is that each of the M uplink resources is used to transmit an SRS.
[0174] In some embodiments, the first uplink resource is determined based on at least one of the following: the length of the second time period, the number M of uplink resources included in the second time period, the number of symbols occupied by one uplink resource in the time domain, and the time domain interval between two adjacent uplink resources. Optionally, the above information is predefined, or the above information is configured by the network device, or some of the above information is predefined and some is configured by the network device. Optionally, the network device is configured using third configuration information.
[0175] For example, the first uplink channel or signal is PRACH, the length of the second time period and the time domain interval between two adjacent uplink resources are predefined, and the number of uplink resources M included in the second time period and the number of symbols occupied by an uplink resource in the time domain are configured by the network device.
[0176] For example, the first uplink channel or signal is PUSCH, PUCCH or UL RS, and the length of the second time period, the number of uplink resources M included in the second time period, the number of symbols occupied by an uplink resource in the time domain, and the time domain interval between two adjacent uplink resources are configured by the network device.
[0177] In some embodiments, when the first uplink resource includes M uplink resources, the M uplink resources correspond to the same frequency domain resource location and size, and / or, the M uplink resources correspond to the same number of symbols.
[0178] In some embodiments, the time-domain resource length corresponding to the first uplink resource mentioned above refers to the number of symbols occupied by one uplink resource in the time domain, and / or the length of the second time period. For example, when the first uplink resource includes one uplink resource, the time-domain resource length corresponding to the first uplink resource mentioned above may refer to the number of symbols occupied by that one uplink resource in the time domain. For example, when the first uplink resource includes M uplink resources, the time-domain resource length corresponding to the first uplink resource mentioned above may refer to the length of the second time period in which the M uplink resources are located.
[0179] In some embodiments, the first configuration information is used to configure the cell DRX of the first cell. If at least a portion of the first uplink resources are located in the inactive period of the cell DRX of the first cell, and the first uplink resources include M uplink resources, where M is greater than 1, whether the first uplink resources are valid includes one of the following:
[0180] (1) All M uplink resources are invalid resources;
[0181] (2) All M uplink resources are valid resources;
[0182] (3) Among the M uplink resources, the uplink resources in the cell DRX of the first cell during the activation period are valid resources, and / or the uplink resources in the cell DRX of the first cell during the non-activation period are invalid resources.
[0183] (4) For each of the M uplink resources, if all symbols of the uplink resource are located within the active period of the cell DRX of the first cell, the uplink resource is a valid resource; and / or, if some or all symbols of the uplink resource are located within the inactive period of the cell DRX of the first cell, the uplink resource is an invalid resource.
[0184] In some embodiments, the first configuration information is used to configure the cell DRX of the first cell. If at least a portion of the first uplink resources are located in the inactive period of the cell DRX of the first cell, and the first uplink resources include one uplink resource, whether the first uplink resource is valid includes one of the following:
[0185] (1) The first uplink resource is an invalid resource;

[0188] Optionally, when the uplink resource is a valid resource, it can be used to transmit a first uplink channel or signal, and the terminal device can transmit the first uplink channel or signal on the valid uplink resource; when the uplink resource is an invalid resource, it cannot be used to transmit the first uplink channel or signal, and the terminal device cannot transmit the first uplink channel or signal on the invalid uplink resource.
[0189] Optionally, the terminal device transmits the first uplink channel or signal on valid resources, and does not transmit the first uplink channel or signal on invalid resources.
[0190] Optionally, the method for determining whether the first uplink resource is valid is predefined or configured by the network device.
[0191] Using the above method, when the first configuration information is used to configure the cell DRX of the first cell, the terminal device and the network device can determine the first uplink resource in the same way and determine whether the first uplink resource is valid in the same way, thereby ensuring that the terminal device and the network device have a consistent understanding of the first uplink resource, which helps to improve the transmission performance of the first uplink channel or signal.
[0192] In some embodiments, the first downlink channel or signal includes at least one of the following: SSB, PDCCH, and DL RS. These are described below in detail.
[0193] Example 1: The first downlink channel or signal includes the SSB.
[0194] Optionally, the SSB mentioned above is the SSB of the first cell.
[0195] Optionally, the first downlink channel or signal includes a first SSB transmission opportunity, which is used to transmit an SSB. Optionally, the first SSB transmission opportunity is an SSB transmission opportunity of the first cell, which is used to transmit the SSB of the first cell.
[0196] Optionally, if the first downlink channel or signal includes a first SSB transmission opportunity, among the SSBs included in the first SSB transmission opportunity, the terminal device should assume that the same SSB indexes have a QCL (Quasi-Colocation) relationship, and / or that different SSB indices do not have a QCL relationship. In other words, the same SSB indexes correspond to the same beam direction, and / or that different SSB indices correspond to different beam directions.
[0197] Optionally, when the first downlink channel or signal includes a first SSB transmission opportunity, the SSB included in the first SSB transmission opportunity has an SSB index and a candidate SSB index, and there is a mapping relationship between the SSB index and the candidate SSB index. Optionally, the mapping relationship between the SSB index and the candidate SSB index is predefined or determined based on the configuration parameters of the network device.
[0198] In some embodiments, the first downlink resource includes N downlink resources, each used to transmit one SSB, where N is an integer greater than 1. The mapping relationship between the first downlink resource, the SSB index, or the candidate SSB index includes at least one of the following:
[0199] (1) Each downlink resource in the first downlink resource corresponds to a candidate SSB index;
[0200] (2) Each downlink resource in the first downlink resource corresponds to an SSB index;
[0201] (3) One candidate SSB index corresponds to one SSB index.
[0202] For example, the first downlink resource includes N downlink resources, each of which corresponds to a candidate SSB index and an SSB index, and the candidate SSB index and the SSB index are in a one-to-one correspondence. For example, the candidate SSB index is C, and the SSB index is T, with C and T corresponding one-to-one. Optionally, C and T have the same value.
[0203] Figure 4 illustrates a schematic diagram of the mapping relationship between the SSB index and candidate SSB indexes of the SSB included in the first SSB transmission opportunity, when the first downlink channel or signal includes the first SSB transmission opportunity. The first SSB transmission opportunity includes N candidate SSB indices, where each candidate SSB index corresponds to one SSB index. Figure 4 gives an example where N is 8, with the 8 candidate SSB indices being 0, 1, 2, 3, 4, 5, 6, and 7 respectively. Correspondingly, the 8 SSB indices are also 0, 1, 2, 3, 4, 5, 6, and 7, meaning the candidate SSB index and the SSB index have the same value.
[0204] In some embodiments, the first downlink resource includes N downlink resources, each used to transmit one SSB, where N is an integer greater than 1. The mapping relationship between the first downlink resource, the SSB index, or the candidate SSB index includes at least one of the following:
[0205] (1) Each downlink resource in the first downlink resource corresponds to a candidate SSB index;
[0206] (2) Each SSB index corresponds to one of the K downlink resources in the first downlink resource;
[0207] (3) K candidate SSB indexes correspond to one SSB index;
[0208] Where K is an integer greater than 1 and less than or equal to N.
[0209] For example, the first downlink resource includes N downlink resources, each of which corresponds to a candidate SSB index. Every K downlink resources and / or every K candidate SSB indices corresponds to one SSB index, and the candidate SSB indexes and SSB indices have a many-to-one relationship. The value of K can be predefined or configured by the network device.
[0210] For example, let C be a candidate SSB index and T be an SSB index. K candidate SSB indices correspond to one SSB index, including: C = T * K + r, where r is an integer in the interval [0, K-1], i.e., r = 0, 1, ..., K-1; C is an integer in the interval [0, N-1], i.e., C includes 0, 1, ..., N-1; and T is an integer in the interval [0, Q-1], i.e., T includes 0, 1, ..., Q-1. Here, Q = N / K, or Q = ceil(N / K), or Q = floor(N / K), where ceil() represents rounding up and floor() represents rounding down.
[0211] Figure 5 illustrates another schematic diagram showing the mapping relationship between the SSB index and candidate SSB indexes of the SSB included in the first SSB transmission opportunity when the first downlink channel or signal includes the first SSB transmission opportunity. The first SSB transmission opportunity includes N candidate SSB indices, where every K candidate SSB indices correspond to one SSB index. Figure 5 gives an example where N is 8, and the candidate SSB index C = T*K + r, where K = 4, Q = N / K = 2, T is an integer in the range [0, 1], and r is an integer in the range [0, 3]. In Figure 5, the 8 candidate SSB indices are 0, 1, 2, 3, 4, 5, 6, 7, and correspondingly, the 8 SSB indices are 0, 0, 0, 0, 1, 1, 1, 1.
[0212] For example, let C be a candidate SSB index and T be an SSB index. K candidate SSB indices correspond to one SSB index, including: T = mod(C, Q), where mod() represents the modulo operation, C is an integer in the interval [0, N-1], i.e., the value of C includes 0, 1, ..., N-1, and T is an integer in the interval [0, Q-1], i.e., the value of T includes 0, 1, ..., Q-1. Here, Q = N / K, or Q = ceil(N / K), or Q = floor(N / K), where ceil() represents rounding up and floor() represents rounding down.
[0213] Figure 6 illustrates another schematic diagram of the mapping relationship between the SSB index and candidate SSB indexes of the SSB included in the first SSB transmission opportunity, when the first downlink channel or signal includes the first SSB transmission opportunity. The first SSB transmission opportunity includes N candidate SSB indices, where every K candidate SSB indices correspond to one SSB index. Figure 6 gives an example where N is 8, and the SSB index T = mod(C, Q), where K = 4, Q = N / K = 2, and T is an integer in the range [0, 1]. In Figure 6, the 8 candidate SSB indices are 0, 1, 2, 3, 4, 5, 6, 7, and correspondingly, the 8 SSB indices are 0, 1, 0, 1, 0, 1, 0, 1.
[0214] In the examples given in Figures 5 and 6 above, multiple downlink resources in the first downlink resource correspond to one SSB index, and multiple candidate SSB indices correspond to one SSB index. The advantage of doing this is that it can increase the transmission density of the same SSB, and the terminal device can obtain the merging result of multiple SSBs as soon as possible, thereby improving the performance of receiving SSBs.
[0215] Example 2: The first downlink channel or signal includes the PDCCH.
[0216] Optionally, the aforementioned PDCCH is the cell public PDCCH or group public PDCCH of the first cell.
[0217] Optionally, the PDCCH described above is used to schedule PDSCH, or the PDCCH described above is not used to schedule PDSCH.
[0218] In some embodiments, the first downlink channel or signal includes one or more PDCCHs for determining at least one of the following:
[0219] (1) Downlink authorization information for scheduling paging message transmission;
[0220] (2) Downlink authorization information for message transmission in the scheduling system;
[0221] (3) Schedule downlink authorization information for broadcast message transmission;
[0222] (4) System message update indication information;
[0223] (5) Whether to listen for paging message indication information during the activation period of the cell DTX of the first cell associated with the first downlink resource;
[0224] (6) Whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes SSB indication information;
[0225] (7) Whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes the indication information of DL RS;
[0226] (8) Indication information on whether to listen to or receive a first downlink channel or signal on at least one downlink resource in the first downlink resources; Optionally, the first downlink channel or signal here includes at least one of PDCCH, SSB, and DL RS;
[0227] (9) Whether the configuration of the cell DTX of the first cell is an indication of the effective configuration, i.e. the first indication information mentioned above;
[0228] (10) Whether the configuration of the cell DRX of the first cell is an effective configuration indication information, i.e. the second indication information mentioned above.
[0229] Optionally, the first downlink channel or signal includes a PDCCH, in which first indication information and / or second indication information are carried; or, the first indication information and / or second indication information are carried in a PDSCH scheduled by the PDCCH.
[0230] For example, the PDCCH is used to determine at least one of the following: first indication information, second indication information, indicating whether a system message is updated, indicating whether paging messages are being listened to during the activation period of the cell DTX of the first cell associated with the first downlink resource, scheduling system message transmission, scheduling paging message transmission, scheduling broadcast message transmission, indicating whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes an SSB, indicating whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes a DL RS, indicating whether the terminal device is listening to or receiving a first downlink channel or signal on at least one downlink resource in the first downlink resource, and indicating whether the network device is transmitting a first downlink channel or signal, wherein the first downlink channel or signal includes at least one of PDCCH, SSB, and DL RS.
[0231] For example, the PDSCH is used to carry at least one of the following: system messages (e.g., SIB1), paging messages, broadcast messages, first indication information, second indication information, indication information for system message updates, indication information for whether paging messages are being listened to during the activation period of the cell DTX of the first cell associated with the first downlink resource, indication information for whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes an SSB, indication information for whether the activation period of the cell DTX of the first cell associated with the first downlink resource includes a DL RS, indication information for whether a first downlink channel or signal is being listened to or received on at least one downlink resource in the first downlink resource, and indication information for whether the network device transmits a first downlink channel or signal, wherein the first downlink channel or signal includes at least one of PDCCH, SSB, and DL RS.
[0232] In some embodiments, the first configuration information is used to configure the cell DTX of the first cell. The first downlink channel or signal includes a first PDCCH, which is used to schedule the first PDSCH. The time-domain resources occupied by the first PDSCH are all within the active period of the cell DTX of the first cell, or the time-domain resources occupied by the first PDSCH are partially within the active period of the cell DTX of the first cell, or the time-domain resources occupied by the first PDSCH are all within the inactive period of the cell DTX of the first cell. When the time-domain resources occupied by the first PDSCH may be partially or entirely within the inactive period of the cell DTX of the first cell, the transmission of the first PDSCH is not affected by the cell DTX of the first cell.
[0233] Example 3: The first downlink channel or signal includes DL RS.
[0234] Optionally, DL RS is used for at least one of the following: downlink CSI measurement, time-frequency synchronization tracking, beam measurement, RRM (Radio Resource Management) measurement, and RLM (Radio Link Monitoring) measurement.
[0235] Optionally, the DL RS is the cell-common DL RS or group-common DL RS of the first cell.
[0236] Optionally, when the first downlink channel or signal is DL RS, the starting position of the first downlink resource is the same as the starting position of the activation period of the cell DTX of the first cell. That is, in this case, including one or more downlink resources for transmitting DL RS starting from the starting position of the activation period of the cell DTX of the first cell can enable the terminal device to receive DL RS as soon as possible after entering the working state from the sleep state, thereby obtaining the time and frequency synchronization information of the first cell as soon as possible.
[0237] In some embodiments, a first downlink resource is associated with a second downlink resource, the second downlink resource being used to transmit a second downlink channel or signal, the second downlink channel or signaling being used to determine at least one of the following:
[0238] (1) System message update indication information;
[0239] (2) Whether to listen for paging message indication information during the activation period of the cell DTX of the first cell associated with the first downlink resource;

[0242] (5) Indication information on whether to listen to or receive the first downlink channel or signal on at least one downlink resource in the first downlink resources;
[0243] (6) Whether the configuration of the cell DTX of the first cell is an indication of the effective configuration, i.e., the first indication information mentioned above;
[0244] (7) Whether the configuration of the cell DRX of the first cell is an indication of the effective configuration, i.e. the second indication information mentioned above.
[0245] Optionally, the association between the first downlink resource and the second downlink resource can be predefined or configured by the network device; this application does not limit this.
[0246] In some embodiments, the starting position of the second downlink resource is the same as the starting position of the activation period of the cell DTX; or, the ending position of the second downlink resource is the same as the starting position of the activation period of the cell DTX; or, the second downlink resource is located within the inactive period of the cell DTX.
[0247] For example, the second downlink resource is associated with the first downlink resource. The second downlink resource is used to transmit first paging early indication (PEI) information. The first downlink resource is the downlink control channel resource used to transmit downlink grant information for scheduling paging messages during the active period of the cell DTX of the first cell. In other words, the first downlink resource is the downlink resource corresponding to the paging occupancy (PO) during the active period of the cell DTX of the first cell. The first PEI information is used to indicate whether the terminal device is listening for paging messages on the second downlink resource.
[0248] In the above embodiments, various possible situations and examples of the first downlink channel or signal are given, and the terminal device can obtain relevant reference signals or indication information accordingly, thereby completing the corresponding communication behavior.

[0263] Optionally, SRS is an uplink channel or signal sent by the terminal device for channel detection.
[0264] In the above embodiments, various possible situations and examples of the first uplink channel or signal are given. The terminal device can use the first uplink channel or signal to send relevant information or signals to the network device, thereby completing the corresponding communication behavior.
[0265] In some embodiments, a first uplink resource is associated with a second downlink resource, the second downlink resource being used to transmit a second downlink channel or signal, the second downlink channel or signal being used to determine at least one of the following:
[0266] (1) Indication information on whether the first uplink resource can be used to transmit the first uplink channel or signal;

[0272] For details not described in the method steps on the network device side, please refer to the description in the above embodiments, which will not be repeated here.
[0273] Example 1
[0274] In some embodiments, the first downlink resource during the activation period of the cell DTX of the first cell is a valid resource; and / or, the first downlink resource during the inactive period of the cell DTX of the first cell is an invalid resource.
[0275] In some embodiments, the first uplink resource during the activation period of the cell DRX of the first cell is a valid resource; and / or, the first uplink resource during the inactive period of the cell DRX of the first cell is an invalid resource.
[0276] In some embodiments, the first downlink channel or signal includes: a first SSB transmission opportunity.
[0277] The second configuration information is used to determine at least one of the following: the SSB index or candidate SSB index included in the first SSB transmission opportunity, the first SSB period, the position of the first SSB transmission opportunity in the first SSB period, and the frequency of the first SSB transmission opportunity.
[0278] For example, the second configuration information is used to configure the SSB index or candidate SSB index included in the first SSB transmission opportunity. The terminal device can determine the time-domain resources used for transmitting the SSB based on the SSB index or candidate SSB index.
[0279] For example, the maximum length corresponding to the first SSB transmission opportunity is fixed, such as 5ms. The number of candidate SSBs included in the first SSB transmission opportunity and the position of each candidate SSB are also fixed. For example, the first SSB transmission opportunity includes 8 candidate SSBs, corresponding to SSB indices 0 to 7 respectively. Each candidate SSB occupies a fixed number of symbols, and the starting symbol index of each candidate SSB in the time domain is related to the SSB index. The terminal device can determine which candidate SSBs in the first SSB transmission opportunity have SSB transmission based on the SSB index configured by the second configuration information, thereby determining the first downlink resource used for SSB transmission.
[0280] For example, the second configuration information is used to configure the offset value between the starting position of the first SSB cycle and the starting position of the first SSB transmission opportunity. The terminal device can determine the position of the first SSB transmission opportunity in the first SSB cycle based on this offset value.
[0281] For example, the first SSB cycle length is 20ms, and the starting position of each cycle is SFN x, where mod(SFN x,2)=0. The maximum length corresponding to the first SSB transmission opportunity is 5ms, and each cycle includes 4 possible time-domain positions for transmitting the first SSB transmission opportunity. The offset value ranges from 0 to 3. When the offset value is 0, the first SSB transmission opportunity occurs in the first 5ms of every 20ms; when the offset value is 1, the first SSB transmission opportunity occurs in the second 5ms of every 20ms; when the offset value is 2, the first SSB transmission opportunity occurs in the third 5ms of every 20ms; and when the offset value is 3, the first SSB transmission opportunity occurs in the fourth 5ms of every 20ms.
[0282] For example, the length of the first SSB cycle is y ms, and the starting position of each cycle is SFN x, where mod(10*x,y) = 0. The offset value is the number of time-domain units included between the starting position of SFN x and the starting position of the first SSB transmission opportunity, or the offset value is the number of time-domain units included between the starting position of the first SSB transmission opportunity and the starting position of SFN x. The unit of this time-domain unit includes one of the following: half-frame, radio frame, maximum length corresponding to the first SSB transmission opportunity, time slot, subframe, or symbol.
[0283] For example, the second configuration information is used to configure the system frame information and / or half-frame information in which the first SSB transmission opportunity is located. The terminal device can determine the position of the first SSB transmission opportunity in the first SSB cycle based on the system frame information and / or half-frame information.
[0284] For example, the first SSB cycle length is y ms, and the starting position of each cycle is SFN x, where mod(10*x,y)=0. The second configuration information configures the number of radio frames offset between SFN x and the system frame where the first SSB transmitter is located. Further, half-frame information is used to indicate whether the first SSB transmitter is located in the first half-frame or the second half-frame of the system frame where the first SSB transmitter is located.
[0285] For example, the second configuration information is used to configure the center frequency of the first SSB transmission opportunity. The terminal device can determine the frequency domain resources occupied by the SSB transmission based on the center frequency.
[0286] For example, the second configuration information is used to configure the ARFCN (Absolute Radio Frequency Channel Number) or GSCN (Global Synchronization Channel Number) value corresponding to the first SSB transmitter.
[0287] Figure 8 illustrates the use of the first downlink resources to transmit the first SSB transmission opportunity. As shown in Figure 8, the first configuration information is used to configure the cell DTX of the first cell, which includes an active period (i.e., "on-demand period") and an inactive period (i.e., "dormant period"). The second configuration information is used to determine or configure the periodic first downlink resources, with each box in Figure 8 representing a first downlink resource. During the active period of the cell DTX of the first cell, the first downlink resources are valid (shown by the diagonal fill line in the figure); during the inactive period of the cell DTX of the first cell, the first downlink resources are invalid (shown by the dashed box in the figure). The terminal device receives the SSBs included in the first SSB transmission opportunity on the valid first downlink resources.
[0288] In some embodiments, the first downlink channel or signal includes at least one of the following: a first PDCCH and a first DL RS.
[0289] The second configuration information is used to determine at least one of the following: the length of the first time period, the number N of downlink resources included in the first time period, the number of symbols occupied by a downlink resource in the time domain, the time domain interval between two adjacent downlink resources, the first downlink resource period, the position of the first downlink resource in the first downlink resource period, and the frequency domain resource position corresponding to the first downlink resource.
[0290] In some embodiments, where the first downlink channel or signal includes a first PDCCH, the second configuration information is used to determine a first search space set corresponding to the first PDCCH. The first downlink resource is a resource in the first search space set.
[0291] For example, the second configuration information is used to determine at least one of the following: the period and offset value of the first search space set, the number N of time-domain PDCCH transmission opportunities included in the first search space set, and the CORESET corresponding to the first search space set (e.g., the starting position of COREST and / or the size of CORESET).
[0292] Figure 9 illustrates a first downlink resource group comprising a set of downlink resources. As shown in Figure 9, the first configuration information is used to configure the cell DTX of the first cell, which includes an active period (i.e., "on-demand") and an inactive period (i.e., "dormant period"). The second configuration information is used to determine or configure periodic first downlink resource groups. Each box in Figure 9 represents a first downlink resource, and each first downlink resource group includes N (N=4) first downlink resources. During the active period of the cell DTX of the first cell, the first downlink resource group is valid (shown by the diagonal fill line in the figure); during the inactive period of the cell DTX of the first cell, the first downlink resource group is invalid (shown by the dashed box in the figure). The terminal device receives the first downlink channel or signal on the valid first downlink resource group.
[0293] In some embodiments, the first uplink channel or signal includes at least one of the following: PRACH, PUSCH, PUCCH, UL RS.
[0294] The third configuration information is used to determine at least one of the following: the length of the second time period, the number M of uplink resources included in the second time period, the number of symbols occupied by an uplink resource in the time domain, the time domain interval between two adjacent uplink resources, the first uplink resource period, the position of the first uplink resource in the first uplink resource period, and the frequency domain resource position corresponding to the first uplink resource.
[0295] In some embodiments, when the first uplink channel or signal is PRACH, or when the first uplink channel or signal is both PRACH and PUSCH, the first uplink resource is a random access resource, and the third configuration information is used to configure the configuration information corresponding to the random access resource.
[0296] Example 2
[0297] In some embodiments, the first downlink channel or signal includes: a first SSB transmission opportunity.
[0298] The second configuration information is used to determine at least one of the following during the activation period of the cell DTX of the first cell: the SSB index or candidate SSB index included in the first SSB transmission opportunity, the first SSB period, the position of the first SSB transmission opportunity in the first SSB period, and the frequency of the first SSB transmission opportunity.
[0299] For example, the second configuration information is used to configure the SSB index or candidate SSB index included in the first SSB transmission opportunity during the activation period of the cell DTX of the first cell. The terminal device can determine the time-domain resources used for transmitting SSBs during the activation period of the cell DTX of the first cell based on the SSB index or candidate SSB index.
[0300] For example, the starting position of the first SSB cycle is the same as the starting position of the activation cycle of the cell DTX of the first cell, or the second configuration information is used to configure the offset value between the starting position of the first SSB cycle and the starting position of the activation cycle of the cell DTX of the first cell.
[0301] For example, the second configuration information is used to configure the offset value between the starting position of the first SSB cycle and the starting position of the first SSB transmission opportunity during the activation period of the cell DTX of the first cell. The terminal device can determine the position of the first SSB transmission opportunity in the first SSB cycle during the activation period of the cell DTX of the first cell based on this offset value.
[0302] For example, the second configuration information is used to configure the system frame information and / or half-frame information where the first SSB transmission opportunity is located during the activation period of the cell DTX of the first cell. The terminal device can determine the position of the first SSB transmission opportunity in the first SSB period based on the system frame information and / or half-frame information.
[0303] For example, the second configuration information is used to configure the center frequency point of the first SSB transmission opportunity. The terminal device can determine the frequency domain resources occupied by SSB transmission during the activation period of the cell DTX of the first cell based on the center frequency point.
[0304] Figure 10 illustrates the use of the first downlink resource for transmitting the first SSB transmission opportunity. As shown in Figure 10, the first configuration information is used to configure the cell DTX of the first cell, the period of which includes an active period (i.e., "on period") and an inactive period (i.e., "dormant period"). The second configuration information is used to determine or configure the first downlink resource during the active period of the cell DTX of the first cell. Each box in Figure 10 represents a first downlink resource. The terminal device receives the SSB included in the first SSB transmission opportunity on the aforementioned first downlink resource during the active period of the cell DTX of the first cell.
[0305] In some embodiments, the first downlink channel or signal includes at least one of the following: a first PDCCH and a first DL RS.
[0306] The second configuration information is used to determine at least one of the following during the activation period of the cell DTX of the first cell: the length of the first time period, the number N of downlink resources included in the first time period, the number of symbols occupied by a downlink resource in the time domain, the time domain interval between two adjacent downlink resources, the first downlink resource period, the position of the first downlink resource in the first downlink resource period, and the position of the frequency domain resource corresponding to the first downlink resource.
[0307] In some embodiments, where the first downlink channel or signal includes a first PDCCH, the second configuration information is used to determine a first search space set corresponding to the first PDCCH. The first downlink resource is a resource in the first search space set.
[0308] For example, the second configuration information is used to determine at least one of the following: the period and offset value of the first search space set during the activation period of the cell DTX of the first cell, the number N of time-domain PDCCH transmission opportunities included in the first search space set during the activation period of the cell DTX of the first cell, and the CORESET (e.g., the starting position of COREST and / or the size of CORESET) corresponding to the first search space set during the activation period of the cell DTX of the first cell.
[0309] Figure 11 illustrates a first downlink resource group comprising a set of downlink resources. As shown in Figure 11, the first configuration information is used to configure the cell DTX of the first cell, the period of which includes an active period (i.e., "on period") and an inactive period (i.e., "dormant period"). The second configuration information is used to determine or configure the first downlink resource group within the active period of the cell DTX of the first cell.
