[0042] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a terminal, the method comprising:
[0043] The first information is sent, where the first information is used to request the network device to send a downlink transmission. The first information is also used by the network device to determine whether to send the downlink transmission.
[0044] In the above embodiment, the terminal sends the first information to the network device to request the network device to send downlink transmission through the first information. The network device can determine whether to send downlink transmission based on the first information, so that the network device can send downlink transmission when the terminal needs it, without having to send downlink transmission periodically, thereby reducing the power consumption of the network device.
[0045] With reference to some embodiments of the first aspect, in some embodiments, sending the first information includes:
[0046] The first information is sent on the first time-frequency resource, where the first time-frequency resource is a time-frequency resource used to send a wake-up signal.
[0047] In the above embodiment, by implementing the sending of the first information on the first time-frequency resource used for sending the wake-up signal, the success rate of sending the first information can be improved to ensure the smooth progress of the downlink transmission allocation process.

[0054] With reference to some embodiments of the first aspect, in some embodiments, the first signaling is cell-specific signaling; or
[0055] The first signaling is user equipment-specific radio resource control signaling.
[0056] In the above embodiment, signaling utilization can be improved by multiplexing the first signaling to implement the indication of the first time-frequency resource.
[0057] In combination with some embodiments of the first aspect, in some embodiments, the first signaling includes configuration information, and the configuration information is used to determine the first time-frequency resource allocated by the network device to the terminal.

[0220] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:
[0221] Step S2101: The terminal sends first information to the network device.
[0222] Optionally, the terminal may be a terminal that supports network technology, that is, the terminal can connect to the network and perform network communication. The network device may be a base station, for example, a base station that supports network energy saving (NES) technology, but is not limited thereto, and the network device may also be other types.
[0223] The first information is used to request the network device to send downlink transmission.
[0224] In some embodiments, the terminal may send first information to the network device on a first time-frequency resource. The first time-frequency resource may be a time-frequency resource used to send a wake-up signal (WUS). The first time-frequency resource may also be referred to as a WUS resource.
[0225] In some embodiments, the first time-frequency resource may be determined based on first signaling received from the network device.
[0226] Optionally, the network device may send a first signaling to the terminal, and the terminal may receive the first signaling sent by the network device, thereby determining the first time-frequency resource based on the first signaling received from the network device.
[0227] Optionally, the first signaling may include configuration information, and the configuration information may be used to determine the first time-frequency resource allocated by the network device to the terminal. Then, after receiving the first signaling sent by the network device, the terminal may determine the first time-frequency resource allocated by the network device to the terminal based on the configuration information in the first signaling.
[0228] Optionally, the first signaling may be cell-specific signaling. The embodiment of the present disclosure does not limit the type of cell-specific signaling. For example, the cell-specific signaling may be System Information Block 1 (SIB1) or other SIBs. Alternatively, the first signaling may also be UE-dedicated RRC signaling.
[0229] That is, the terminal may determine the first time-frequency resource based on the configuration information in the cell-specific signaling, or the terminal may determine the first time-frequency resource based on the configuration information in the UE-dedicated RRC signaling.
[0230] In some embodiments, the first time-frequency resource may not be a time-frequency resource used to transmit the second information, and the second information may be any one of confirmation (Acknowledgement, ACK) information, negative acknowledgement (Negative Acknowledgement, NACK) information, and scheduling request (Scheduling Request, SR) information. That is, the first time-frequency resource may be a PUCCH resource different from the traditional one used to carry ACK information, NACK information and SR information (in other words, the first time-frequency resource is an additional time-frequency resource).
[0231] In some embodiments, the first time-frequency resource may also be a physical uplink control channel (PUCCH) resource or multiple PUCCH resources in a PUCCH resource set, that is, the first time-frequency resource can be a time-frequency resource shared with other devices using the traditional PUCCH format (for example, the first time-frequency resource can be shared with the traditional PUCCH resource (legacy PUCCH resource) used in the LTE (Long-Term Evolution) system).
[0232] The first time-frequency resource is not a time-frequency resource used to transmit the second information, or the first time-frequency resource is a PUCCH resource or multiple PUCCH resources in the PUCCH resource set. The first instruction may also include indication information, which can be used to indicate the resource identifier of the first time-frequency resource allocated by the network device to the terminal. The resource identifier may be a resource number, but is not limited to this.
[0233] In some embodiments, the terminal is in an idle (IDLE) state or an inactive (INACTIVE) state, and the terminal can save the configuration information in the first signaling.
[0234] That is, when the terminal is in an idle state or an inactive state, the terminal may not release the first signaling, so that the first time-frequency resource can be determined subsequently according to the unreleased configuration information.
[0235] In some embodiments, the first time-frequency resource may also be predefined by a protocol, that is, the terminal may determine the first time-frequency resource in a manner predefined by the protocol, or the terminal may obtain the first time-frequency resource predefined by the protocol.
[0236] In some embodiments, if the network device is not configured with a cell-specific discontinuous transmission (DTX) / discontinuous reception (DRX) mode (i.e., a cell-specific DTX / DRX pattern), the first time-frequency resource may be an uplink time-frequency resource that is currently active. Alternatively, if the network device is configured but has not activated a cell-specific DTX / DRX pattern, the first time-frequency resource may be an uplink time-frequency resource that is currently active.
[0237] That is, the network device is not configured with a cell-specific DTX / DRX pattern, or the network device is configured but not activated with a cell-specific DTX / DRX pattern, then the terminal may send the first information within the active duration.
[0238] In some embodiments, the network device has configured and activated a cell-specific DTX / DRX mode, and the first time-frequency resource may include an uplink time-frequency resource that is currently active and / or an uplink time-frequency resource that is currently in an inactive state.
[0239] That is, when the network device configures and activates the cell-specific DTX / DRX pattern, the terminal can send the first information not only within the active duration, but also within the inactive duration.
[0240] Optionally, the first time-frequency resource may be a single time-frequency resource that appears periodically; or, the first time-frequency resource may include multiple time-frequency resources, for example, the first time-frequency resource may include multiple time-frequency resources that appear periodically.
[0241] In some embodiments, the first time-frequency resource is a single time-frequency resource that appears periodically. When the terminal sends the first information on the first time-frequency resource, it may use a specific sequence to send the first information on the first time-frequency resource, or it may use multiple sequences to send the first information on the first time-frequency resource. That is, when the first time-frequency resource is a single time-frequency resource that appears periodically, the embodiments of the present disclosure do not limit the number of sequences used to carry the first information.
[0242] Optionally, when multiple sequences are used to send the first information on the first time-frequency resource, the multiple sequences used to carry the first information can be multiple sequences with different cyclic shifts on the first time-frequency resource. Different sequences can be used to carry the first information requesting the network device to send different types of downlink transmissions, that is, the type of downlink transmission requested by the first information carried on different sequences can be different.
[0243] In some embodiments, the correspondence between the sequence and the downlink transmission may be determined based on an indication of higher layer signaling, or may be determined in a manner predefined by a protocol.
[0244] Optionally, the first time-frequency resource includes multiple time-frequency resources, and different time-frequency resources can be used to carry first information requesting the network device to send different types of downlink transmissions. That is, the first information carried on different time-frequency resources can request different types of downlink transmissions. In addition, multiple sequences can be transmitted on multiple time-frequency resources, and the first information carried by the multiple sequences transmitted on the multiple time-frequency resources can be used by the terminal to request the network device to send different types of downlink transmissions.
[0245] In some embodiments, the correspondence between time-frequency resources and downlink transmission may be determined based on an indication of higher-layer signaling; or, the correspondence between time-frequency resources and downlink transmission may be determined in a manner predefined by a protocol.
[0246] In some embodiments, the correspondence between multiple sequences transmitted on multiple time-frequency resources and downlink transmission can be determined based on the indication of high-layer signaling; or, the correspondence between multiple sequences transmitted on multiple time-frequency resources and downlink transmission can be determined in a manner predefined by the protocol.
[0247] In some embodiments, the terminal may send a PUCCH in a first format to the network device, where the PUCCH in the first format includes the first information. The PUCCH in the first format may be a physical uplink control channel format 0 (PUCCH format #0).
[0248] For example, the terminal may send PUCCH format #0 to the network device on the first time-frequency resource. The PUCCH format #0 may include first information for requesting the network device to send downlink transmission.
[0249] Optionally, the downlink transmission may include a downlink channel and / or a downlink signal.
[0250] Optionally, the downlink channel may include at least one of SIB1, a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), but is not limited thereto. The downlink channel may also be of other types.
[0251] Optionally, the downlink signal may include a synchronization signal block (Synchronization Signal Block, SSB), a tracking reference signal (Tracking Reference Signal, TRS), and a channel state information reference signal (CSI-RS), but is not limited thereto, and the downlink signal may also be of other types.
[0252] In some embodiments, the first time-frequency resource overlaps with the time-frequency resource used to transmit the second information, and the second information is sent on the first time-frequency resource.
[0253] Optionally, the second information may be ACK information, NACK information, or SR information, but is not limited thereto. The second information may also be of other types, and it is only necessary to ensure that the second information is information that can be transmitted on the PUCCH of the first format.
[0254] That is, when the first time-frequency resource overlaps with other PUCCH format#0 resources configured by the network device for the terminal, the terminal can send information on the PUCCH format#0 resource as needed, and the information sent includes but is not limited to ACK information, NACK information and SR information.
[0255] In some embodiments, after sending the first information to the network device, the terminal may detect and receive downlink transmission on the first first time-frequency resource that is first transmitted after the first information is transmitted for a first duration. Optionally, the first duration may be determined based on the capabilities of the terminal, or the first duration may be determined based on the configuration of the network device.
[0256] Step S2102: The network device determines whether to send a downlink transmission based on the first information.
[0257] In some embodiments, the network device may receive first information sent by the terminal, and thereby determine whether to send downlink transmission based on the received first information.
[0258] In some embodiments, the network device may detect and receive the first information on the first time-frequency resource (ie, the WUS resource).
[0259] As described in step S2101, the first time-frequency resource can be predefined by the protocol or configured by the network device. For the first time-frequency resource configured by the network device, the network device can send a first signaling to the terminal so that the terminal can determine the first time-frequency resource based on the first signaling. The specific implementation method can be found in step S2101 and will not be repeated here.
[0260] In some embodiments, the first time-frequency resource is not a time-frequency resource used to transmit the second information, or the first time-frequency resource is a PUCCH resource or multiple PUCCH resources in a PUCCH resource set, then the first signaling sent by the network device to the terminal needs to include indication information, and the indication information is used to indicate the resource identifier (such as the resource number) of the first time-frequency resource allocated by the network device to the terminal.
[0261] Optionally, the second information may be ACK information, NACK information, and SR information, but is not limited thereto.
[0262] In some embodiments, the network device may receive the first information on a single first time-frequency resource that occurs periodically.
[0263] Optionally, the network device may receive the first information on a specific sequence of a single first time-frequency resource that appears periodically; or, the network device may receive the first information on multiple sequences of a single first time-frequency resource that appears periodically.
[0264] It should be noted that the network device receives the first information on multiple sequences of a single first time-frequency resource that appears periodically. These multiple sequences can be multiple sequences with different cyclic shifts on the first time-frequency resource, and the downlink transmission type requested by the first information carried by different sequences is different.
[0265] Optionally, the correspondence between the sequence and the downlink transmission may be determined based on an indication of a higher layer signaling, or the correspondence between the sequence and the downlink transmission may be predefined by a protocol.
[0266] In some embodiments, the network device may receive the first information on multiple first time-frequency resources, or may receive the first information on multiple sequences transmitted on multiple first time-frequency resources.
[0267] For example, the network device may receive the first information on a plurality of first time-frequency resources that appear periodically. Alternatively, the network device may receive the first information on a plurality of sequences transmitted on a plurality of first time-frequency resources that appear periodically.
[0268] It should be noted that the network device receives the first information on multiple first time-frequency resources, and the downlink transmission type requested by the first information carried on different time-frequency resources may be different; the network device receives the first information on multiple sequences transmitted on multiple first time-frequency resources, and the downlink transmission type requested by the first information carried by multiple sequences transmitted on multiple time-frequency resources may be different.
[0269] Optionally, the correspondence between time domain resources and downlink transmission can be determined based on the indication of high-level signaling, or the correspondence between time domain resources and downlink transmission can be predefined by the protocol; in addition, the correspondence between sequence and downlink transmission can be determined based on the indication of high-level signaling, or the correspondence between sequence and downlink transmission can be predefined by the protocol.
[0270] In some embodiments, the network device is not configured with a cell DTX / DRX mode, or the network device is configured but the cell-specific DTX / DRX mode is not activated, then the network device can detect and receive the first information on the currently active uplink time-frequency resource, and the currently active uplink time-frequency resource is the first time-frequency resource.
[0271] That is, the network device is not configured with a cell-specific DTX / DRX pattern, or the network device is configured but not activated with a cell-specific DTX / DRX pattern, then the network device may detect and receive the first information within the active duration.
[0272] In some embodiments, if the network device has been configured and activated a cell-specific DTX / DRX mode, the network device can detect and receive the first information on the uplink time-frequency resources that are currently active and / or the uplink time-frequency resources that are currently inactive, and the uplink time-frequency resources that are currently active and / or the uplink time-frequency resources that are currently inactive can both be used as the first time-frequency resources.
[0273] That is, when the network device configures and activates the cell-specific DTX / DRX pattern, the network device can detect and receive the first information not only within the active duration, but also within the inactive duration.
[0274] In some embodiments, the network device may receive a PUCCH in a first format, where the PUCCH in the first format includes the first information. Optionally, the PUCCH in the first format may be PUCCH format #0.
[0275] In some embodiments, after receiving the first information, the network device may send a downlink transmission matching the downlink transmission type requested by the first information to the terminal based on the received first information.
[0276] Optionally, the downlink transmission may include a downlink channel and / or a downlink signal. For an introduction to the downlink channel and the downlink signal, please refer to step S2101 and will not be repeated here.
[0277] In some embodiments, the first time-frequency resource overlaps with the time-frequency resource used to transmit the second information. The network device can detect and receive the second information on the first time-frequency resource. For an introduction to the second information, please refer to step S2101 and will not be repeated here.
[0278] For example, when the first time-frequency resource overlaps with other PUCCH format#0 resources configured by the network device for the terminal, the network device can detect and receive second information such as ACK information, NACK information and SR information on the PUCCH format#0 resource as needed, but is not limited to this.
[0279] In some embodiments, the network device may configure a first duration for the terminal so that the terminal can detect and receive downlink transmission on the first first time-frequency resource after the first information is sent for the first duration.

[0362] In some embodiments, step S3201 is optional and may be omitted or replaced in different embodiments.
[0363] Through the communication method provided by the embodiments of the present disclosure, a terminal supporting network skills sends a PUCCH carrying first information to a network device (such as a base station) supporting network energy-saving technology, and requests the network device to send a downlink transmission (including a downlink channel and / or a downlink signal) through the first information carried on the PUCCH; the network device supporting network energy-saving technology receives the PUCCH carrying the first information sent by the terminal, and determines whether to send the corresponding downlink transmission based on the first information.
[0364] According to the communication method provided in the embodiments of the present disclosure, the terminal can request the network device to send downlink transmission through the following optional implementation methods:
[0365] Optional implementation manner 1: The terminal sends PUCCH format #0 using a specific sequence on a single first time-frequency resource (ie, a WUS resource) that appears periodically. The PUCCH format #0 includes first information for requesting a network device to send downlink transmission.
[0366] Optionally, the terminal may determine the first time-frequency resource occupied by PUCCH format#0 according to the following method:
[0367] Configuration information in cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or,
[0368] Configuration information in UE-dedicated RRC signaling; or,
[0369] The protocol is predefined.
[0370] In some embodiments, when the terminal is in IDLE state or INACTIVE state, the configuration information may not be released so that the terminal can still send PUCCH format#0 on the first time-frequency resource according to the unreleased configuration information to request the network device to send the corresponding downlink transmission.
[0371] In some embodiments, when the first time-frequency resource overlaps with other PUCCH format#0 resources configured by the network device for the terminal, the terminal sends second information on the first time-frequency resource as needed, and the second information includes but is not limited to ACK information, NACK information and SR information.
[0372] In some embodiments, the first time-frequency resource is an additional PUCCH resource, or the first time-frequency resource is shared with a legacy PUCCH resource, that is, the first time-frequency resource is one or more PUCCH resources in a PUCCH resource set, and the network device needs to clearly indicate to the terminal the specific resource number of the first time-frequency resource allocated to it.
[0373] In some embodiments, the terminal may send the first information on a specific sequence of the first time-frequency resource when the network device is required to send a downlink transmission. The specific sequence may be any sequence in the first time-frequency resource.
[0374] In some embodiments, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the terminal's capabilities, or the first duration is determined by configuration information sent by the network device.
[0375] For ease of understanding, optional implementation method 1 is introduced below using a specific embodiment.
[0376] In an embodiment of the present disclosure, the network device may be a base station that supports network energy-saving technology. The network device may choose to stop sending part of the downlink transmission based on the network load, the number of resident terminals, the service type, the service period, etc. The embodiment of the present disclosure does not limit the decision-making process and decision-making strategy of whether the network device sends part of the downlink transmission. After receiving the first information sent by the terminal, the network device may choose to resume sending the downlink transmission based on the first information sent by the terminal. In an embodiment of the present disclosure, the network device may determine to send any one or any combination of the following downlink signals (or channels) based on the terminal request:
[0377] SSB; SIB1; TRS; PDCCH; PDSCH; CSI-RS; other newly defined downlink reference signals, such as the combination of the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), or the demodulation reference signal (DRS), etc.
[0378] In an embodiment of the present disclosure, a terminal may send a PUCCH to a network device to request the network device to send a downlink transmission using first information carried on the PUCCH. For example, the terminal may send a PUCCH format #0 to the network device to carry the first information using the PUCCH format #0. The PUCCH format #0 may also be referred to as a wake-up signal (WUS).
[0379] In the disclosed embodiment, a terminal transmits first information using a specific sequence on a single, periodically occurring first time-frequency resource. This specific sequence can be used to carry the first information, allowing the characteristic sequence to be used to request a network device to send a downlink transmission. The first time-frequency resource is used by the terminal to transmit PUCCH format #0, which carries a sequence used to request a network device to send a downlink transmission.
[0380] In the embodiment of the present disclosure, the terminal may determine the first time-frequency resource by the following method:
[0381] Determined according to configuration information in the cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or
[0382] Determined according to the configuration information in the UE-dedicated RRC signalling sent by the network device; or,
[0383] It is determined in a manner predefined in the protocol, that is, the terminal sends PUCCH format #0 on the default resource specified in the protocol to request the network device to send downlink transmission.
[0384] The embodiments of the present disclosure do not make any provisions for the state of the terminal. For example, the embodiments of the present disclosure can be applied to terminals in a connected state, as well as to terminals in an idle state or an inactive state. This patent also does not impose any restrictions on the type of network device that transmits the configuration of the first time-frequency resource. For example, the relevant configuration information in the present disclosure can be sent by the network device that the terminal requests downlink transmission, or it can be sent by other network devices.
[0385] Since the PUCCH format#0 resource used to request the network device to send downlink transmission may conflict with other PUCCH format#0 resources used to send ACK information, NACK information or SR information, in this scenario, the terminal can send ACK information, NACK information or SR information as needed on the overlapping resources.
[0386] For the first time-frequency resource used to send PUCCH format#0, it can be an additional PUCCH resource configured or determined by any of the aforementioned methods, that is, the first time-frequency resource can be different from the traditional time-frequency resource used to carry ACK information, NACK information or SR information; or, the first time-frequency resource used to send PUCCH format#0 is shared with the legacy PUCCH resource, that is, one or more PUCCH resources can be selected in the PUCCH resource set by any of the aforementioned methods for sending the first information. In the above scenario, the network device needs to inform the terminal of the resource identifier of the PUCCH resource used to send the first information, and the PUCCH resource used to send the first information cannot be used to send PUCCH format#0 carrying HARQ-ACK information or SR information.
[0387] Based on the above configuration, when the terminal needs to request the network device to send a downlink transmission, it can send PUCCH format #0 on the first time-frequency resource, carrying the first information requesting the network device to send a downlink transmission. In the embodiment of the present disclosure, the terminal can send any allowed sequence on the first time-frequency resource to request the network device to send a downlink transmission.
[0388] When the terminal is in the IDLE state or the INACTIVE state, the configuration information may not be released, and the terminal may still send PUCCH format#0 on the corresponding first time-frequency resource according to the configuration information to request the network device to send the corresponding downlink transmission.
[0389] Furthermore, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the capability of the terminal, or the first duration is determined by configuration information sent by the network device.
[0390] After detecting and receiving the first information sent by the terminal, the network device may send a downlink transmission that matches the downlink transmission type requested by the terminal.
[0391] Based on the embodiment corresponding to Optional Implementation 1, the transmission timing of the downlink transmission can be seen in Figure 4A. Figure 4A is a schematic diagram of the transmission timing of the first information according to an embodiment of the present disclosure. As shown in Figure 4A, the WUS signal can be used to carry the first information, and the downlink transmission requested by the WUS signal is SSB. In addition, it should be noted that during the SSB OFF period, the network device may selectively transmit other channels or signals, which is not limited in the embodiment of the present disclosure.
[0392] Optional implementation manner 2: The terminal uses multiple sequences to send PUCCH format #0 on a single first time-frequency resource (ie, WUS resource) that appears periodically. PUCCH format #0 includes first information for requesting the network device to send downlink transmission.
[0393] Optionally, the terminal may determine the first time-frequency resource occupied by PUCCH format#0 according to the following method:
[0394] Configuration information in cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or,
[0395] Configuration information in UE-dedicated RRC signaling; or,
[0396] The protocol is predefined.
[0397] In some embodiments, when the terminal is in IDLE state or INACTIVE state, the configuration information may not be released so that the terminal can still send PUCCH format#0 on the first time-frequency resource according to the unreleased configuration information to request the network device to send the corresponding downlink transmission.
[0398] In some embodiments, when the first time-frequency resource overlaps with other PUCCH format#0 resources configured by the network device for the terminal, the terminal sends second information on the first time-frequency resource as needed, and the second information includes but is not limited to ACK information, NACK information and SR information.
[0399] In some embodiments, the first time-frequency resource is an additional PUCCH resource, or the first time-frequency resource is shared with a legacy PUCCH resource, that is, the first time-frequency resource is one or more PUCCH resources in a PUCCH resource set, and the network device needs to clearly indicate to the terminal the specific resource number of the first time-frequency resource allocated to it.
[0400] In some embodiments, the terminal may send the first information on multiple sequences of the first time-frequency resource when requiring the network device to send a downlink transmission. Different sequences may be used to carry the first information requesting different types of downlink transmissions.
[0401] Optionally, the correspondence between the sequence and the downlink transmission is determined by one of the following methods:
[0402] Configuration is performed through higher-layer signaling;
[0403] Determined by a method predefined by the protocol.
[0404] In some embodiments, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the terminal's capabilities, or the first duration is determined by configuration information sent by the network device.
[0405] For ease of understanding, optional implementation method 2 is introduced below using a specific embodiment.
[0406] In an embodiment of the present disclosure, the network device may be a base station that supports network energy-saving technology. The network device may choose to stop sending part of the downlink transmission based on the network load, the number of resident terminals, the service type, the service period, etc. The embodiment of the present disclosure does not limit the decision-making process and decision-making strategy of whether the network device sends part of the downlink transmission. After receiving the first information sent by the terminal, the network device may choose to resume sending the downlink transmission based on the first information sent by the terminal. In an embodiment of the present disclosure, the network device may determine to send any one or any combination of the following downlink signals (or channels) based on the terminal request:
[0407] SSB; SIB1; TRS; PDCCH; PDSCH; CSI-RS; other newly defined downlink reference signals, such as the combination of the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), or the demodulation reference signal (DRS), etc.
[0408] In an embodiment of the present disclosure, a terminal may send a PUCCH to a network device to request the network device to send a downlink transmission using first information carried on the PUCCH. For example, the terminal may send a PUCCH format #0 to the network device to carry the first information using the PUCCH format #0. The PUCCH format #0 may also be referred to as a wake-up signal (WUS).
[0409] In the disclosed embodiment, a terminal transmits first information using a specific sequence on a single, periodically occurring first time-frequency resource. This specific sequence can be used to carry the first information, allowing the characteristic sequence to be used to request a network device to send a downlink transmission. The first time-frequency resource is used by the terminal to transmit PUCCH format #0, which carries a sequence used to request a network device to send a downlink transmission.
[0410] In the embodiment of the present disclosure, the terminal may determine the first time-frequency resource by the following method:
[0411] Determined according to configuration information in the cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or
[0412] Determined according to the configuration information in the UE-dedicated RRC signalling sent by the network device; or,
[0413] It is determined in a manner predefined in the protocol, that is, the terminal sends PUCCH format #0 on the default resource specified in the protocol to request the network device to send downlink transmission.
[0414] The embodiments of the present disclosure do not make any provisions for the state of the terminal. For example, the embodiments of the present disclosure can be applied to terminals in a connected state, as well as to terminals in an idle state or an inactive state. This patent also does not impose any restrictions on the type of network device that transmits the configuration of the first time-frequency resource. For example, the relevant configuration information in the present disclosure can be sent by the network device that the terminal requests downlink transmission, or it can be sent by other network devices.
[0415] Since the PUCCH format#0 resource used to request the network device to send downlink transmission may conflict with other PUCCH format#0 resources used to send ACK information, NACK information or SR information, in this scenario, the terminal can send ACK information, NACK information or SR information as needed on the overlapping resources.
[0416] For the first time-frequency resource used to send PUCCH format#0, it can be an additional PUCCH resource configured or determined by any of the aforementioned methods, that is, the first time-frequency resource can be different from the traditional time-frequency resource used to carry ACK information, NACK information or SR information; or, the first time-frequency resource used to send PUCCH format#0 is shared with the legacy PUCCH resource, that is, one or more PUCCH resources can be selected in the PUCCH resource set by any of the aforementioned methods for sending the first information. In the above scenario, the network device needs to inform the terminal of the resource identifier of the PUCCH resource used to send the first information, and the PUCCH resource used to send the first information cannot be used to send PUCCH format#0 carrying HARQ-ACK information or SR information.
[0417] Based on the above configuration, when the terminal needs to request the network device to send a downlink transmission, it can send PUCCH format #0 on the first time-frequency resource to carry the first information requesting the network device to send a downlink transmission. In the embodiment of the present disclosure, the terminal can send multiple sequences on the first time-frequency resource to request the network device to send a downlink transmission.
[0418] Optionally, multiple sequences for carrying the first information can be determined in a manner predefined by the protocol. For example, multiple sequences of specific cyclic shifts can be used as multiple sequences for carrying the first information. Multiple sequences for carrying the first information can also be configured by a network device, that is, the network device can specify which cyclic shift sequence is used as the sequence for carrying the first information.
[0419] Furthermore, the above sequence may correspond to a transmission beam of a downlink signal and / or channel, such as one or more corresponding SSB indices.
[0420] The correspondence between the sequence and the downlink transmission may be configured through high-layer signaling, or may be determined in a protocol predefined manner, which is not limited in the embodiments of the present disclosure.
[0421] When the terminal is in the IDLE state or the INACTIVE state, the configuration information may not be released, and the terminal may still send PUCCH format#0 on the corresponding first time-frequency resource according to the configuration information to request the network device to send the corresponding downlink transmission.
[0422] Furthermore, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the capability of the terminal, or the first duration is determined by configuration information sent by the network device.
[0423] After detecting and receiving the first information sent by the terminal, the network device may send a downlink transmission that matches the downlink transmission type requested by the terminal.
[0424] Based on the embodiment corresponding to Optional Implementation 2, the transmission timing of the downlink transmission can be seen in Figure 4B. Figure 4B is a schematic diagram of the transmission timing of the first information according to an embodiment of the present disclosure. As shown in Figure 4B, the WUS signal can be used to carry the first information, and the downlink transmission requested by the WUS signal is SSB. In addition, it should be noted that during the SSB OFF period, the network device may selectively transmit other channels or signals, which is not limited in the embodiment of the present disclosure.
[0425] Assuming that the terminal can request the network device to send SSB through three different sequences, and assuming that the SSB transmission pattern is case A and is below 3 GHz, there are 4 SSBs in the system. In the embodiment of the present disclosure, it is assumed that the correspondence between the terminal sending sequence and the SSB is as follows:
[0426] Sequence #1 corresponds to SSB #0 and SSB #1;
[0427] Sequence #2 corresponds to SSB #2 and SSB #3;
[0428] Sequence#3 corresponds to SSB#0, SSB#1, SSB#2 and SSB#4.
[0429] In order to fully illustrate the scheme of this embodiment, it is assumed that the terminal sends different sequences at three different WUS transmission positions. As can be seen from Figure 4B, when the network device does not receive any WUS signal sent by any terminal, the network device does not need to send SSB; when the network device receives sequence #1 sent by the terminal, the network device sends SSB #0 and SSB #1; when the network device receives sequence #2 sent by the terminal, the network device sends SSB #2 and SSB #3; when the network device receives sequence #3 sent by the terminal, the network device sends SSB #0, SSB #1, SSB #2 and SSB #4.
[0430] Optional implementation manner 3: The terminal sends PUCCH format #0 on multiple first time-frequency resources (that is, WUS resources), where PUCCH format #0 includes first information for requesting the network device to send downlink transmission.
[0431] For example, the terminal may send PUCCH format #0 on a plurality of periodically occurring first time-frequency resources (ie, WUS resources).
[0432] Optionally, the terminal may determine the first time-frequency resource occupied by PUCCH format#0 according to the following method:
[0433] Configuration information in cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or,
[0434] Configuration information in UE-dedicated RRC signaling; or,
[0435] The protocol is predefined.
[0436] In some embodiments, when the terminal is in IDLE state or INACTIVE state, the configuration information may not be released so that the terminal can still send PUCCH format#0 on the first time-frequency resource according to the unreleased configuration information to request the network device to send the corresponding downlink transmission.
[0437] In some embodiments, when the first time-frequency resource overlaps with other PUCCH format#0 resources configured by the network device for the terminal, the terminal sends second information on the first time-frequency resource as needed, and the second information includes but is not limited to ACK information, NACK information and SR information.
[0438] In some embodiments, the first time-frequency resource is an additional PUCCH resource, or the first time-frequency resource is shared with a legacy PUCCH resource, that is, the first time-frequency resource is one or more PUCCH resources in a PUCCH resource set, and the network device needs to clearly indicate to the terminal the specific resource number of the first time-frequency resource allocated to it.
[0439] In some embodiments, when the network device is required to send a downlink transmission, the terminal may send the first information on multiple time-frequency resources included in the first time-frequency resource, and different time-frequency resources may be used to carry the first information requesting different types of downlink transmissions; or, the first information may be sent on multiple sequences transmitted on multiple first time-frequency resources, and different sequences may be used to carry the first information requesting different types of downlink transmissions.
[0440] Optionally, the correspondence between the sequence and the downlink transmission and the correspondence between the time-frequency resources and the downlink transmission may be determined by one of the following methods:
[0441] Configuration is performed through higher-layer signaling;
[0442] Determined by a method predefined by the protocol.
[0443] In some embodiments, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the terminal's capabilities, or the first duration is determined by configuration information sent by the network device.
[0444] For ease of understanding, optional implementation method 3 is introduced below using a specific embodiment.
[0445] In an embodiment of the present disclosure, the network device may be a network device that supports network energy-saving technology. The network device may choose to stop sending part of the downlink transmission based on the network load, the number of resident terminals, the service type, the service period, etc. The embodiment of the present disclosure does not limit the decision-making process and decision-making strategy of whether the network device sends part of the downlink transmission. After receiving the first information sent by the terminal, the network device may choose to resume sending the downlink transmission based on the first information sent by the terminal. In an embodiment of the present disclosure, the network device may determine to send any one or any combination of the following downlink signals (or channels) based on the terminal request:
[0446] SSB; SIB1; TRS; PDCCH; PDSCH; CSI-RS; other newly defined downlink reference signals, such as the combination of the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), or the demodulation reference signal (DRS), etc.
[0447] In an embodiment of the present disclosure, a terminal may send a PUCCH to a network device to request the network device to send a downlink transmission using first information carried on the PUCCH. For example, the terminal may send a PUCCH format #0 to the network device to carry the first information using the PUCCH format #0. The PUCCH format #0 may also be referred to as a wake-up signal (WUS).
[0448] In the disclosed embodiment, a terminal transmits first information using a specific sequence on a single, periodically occurring first time-frequency resource. This specific sequence can be used to carry the first information, allowing the characteristic sequence to be used to request a network device to send a downlink transmission. The first time-frequency resource is used by the terminal to transmit PUCCH format #0, which carries a sequence used to request a network device to send a downlink transmission.
[0449] In the embodiment of the present disclosure, the terminal may determine the first time-frequency resource by the following method:
[0450] Determined according to configuration information in the cell-specific signaling sent by the network device. The embodiment of the present disclosure does not limit the type of cell-specific signaling, including but not limited to SIB1 or other SIBs; or
[0451] Determined according to the configuration information in the UE-dedicated RRC signalling sent by the network device; or,
[0452] It is determined in a manner predefined in the protocol, that is, the terminal sends PUCCH format #0 on the default resource specified in the protocol to request the network device to send downlink transmission.
[0453] The embodiments of the present disclosure do not make any provisions for the state of the terminal. For example, the embodiments of the present disclosure can be applied to terminals in a connected state, as well as to terminals in an idle state or an inactive state. This patent also does not impose any restrictions on the type of network device that transmits the configuration of the first time-frequency resource. For example, the relevant configuration information in the present disclosure can be sent by the network device that the terminal requests downlink transmission, or it can be sent by other network devices.
[0454] Since the PUCCH format#0 resource used to request the network device to send downlink transmission may conflict with other PUCCH format#0 resources used to send ACK information, NACK information or SR information, in this scenario, the terminal can send ACK information, NACK information or SR information as needed on the overlapping resources.
[0455] For the first time-frequency resource used to send PUCCH format#0, it can be an additional PUCCH resource configured or determined by any of the aforementioned methods, that is, the first time-frequency resource can be different from the traditional time-frequency resource used to carry ACK information, NACK information or SR information; or, the first time-frequency resource used to send PUCCH format#0 is shared with the legacy PUCCH resource, that is, one or more PUCCH resources can be selected in the PUCCH resource set by any of the aforementioned methods for sending the first information. In the above scenario, the network device needs to inform the terminal of the resource identifier of the PUCCH resource used to send the first information, and the PUCCH resource used to send the first information cannot be used to send PUCCH format#0 carrying HARQ-ACK information or SR information.
[0456] Based on the above configuration, when a terminal needs to request a network device to send a downlink transmission, it can send PUCCH format #0 on the first time-frequency resource, carrying the first information requesting the network device to send a downlink transmission. In an embodiment of the present disclosure, the terminal can send a specific sequence on multiple time-frequency resources included in the first time-frequency resource to request the network device to send a downlink transmission.
[0457] Optionally, the specific sequence used to carry the first information can be determined in a manner predefined by the protocol, for example, a specific cyclic shift sequence can be used as the sequence used to carry the first information; the sequence used to carry the first information can also be configured by a network device, that is, the network device can specify which cyclic shift sequence is used as the sequence used to carry the first information.
[0458] The disclosed embodiments also support different sequences on different timing resources corresponding to transmit beams for downlink transmissions, such as corresponding one or more SSB indices. That is, a terminal may transmit multiple sequences on multiple time-frequency resources included in the first time-frequency resource to request a network device to transmit a downlink transmission. The time-frequency resources may correspond to transmit beams for downlink signals and / or channels, such as corresponding one or more SSB indices.
[0459] The correspondence between the sequence and the downlink transmission, and the correspondence between the time-frequency resources and the downlink transmission can be configured through high-layer signaling, or can be determined in a protocol predefined manner, which is not limited in the embodiments of the present disclosure.
[0460] When the terminal is in the IDLE state or the INACTIVE state, the configuration information may not be released, and the terminal may still send PUCCH format#0 on the corresponding first time-frequency resource according to the configuration information to request the network device to send the corresponding downlink transmission.
[0461] Furthermore, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the capability of the terminal, or the first duration is determined by configuration information sent by the network device.
[0462] After detecting and receiving the first information sent by the terminal, the network device may send a downlink transmission that matches the downlink transmission type requested by the terminal.
[0463] Based on the embodiment corresponding to Optional Implementation 3, the transmission timing of the downlink transmission can be seen in Figure 4C. Figure 4C is a schematic diagram of the transmission timing of the first information according to an embodiment of the present disclosure. As shown in Figure 4C, the WUS signal can be used to carry the first information, and the downlink transmission requested by the WUS signal is SSB. In addition, it should be noted that during the SSB OFF period, the network device may selectively transmit other channels or signals, which is not limited in the embodiment of the present disclosure.
[0464] Assuming that the terminal can request the network device to send SSB through three different time-frequency resources, and assuming that the SSB transmission pattern is case A and is below 3 GHz, there are 4 SSBs in the system. In the embodiment of the present disclosure, it is assumed that the correspondence between the terminal transmission sequence and the SSB is as follows:
[0465] Sequence #1 on Resource #1 corresponds to SSB #0;
[0466] Sequence #2 on Resource #1 corresponds to SSB #1;
[0467] Sequence #1 on Resource #2 corresponds to SSB #2;
[0468] Sequence #2 on Resource #2 corresponds to SSB #3;
[0469] The Sequence on Resource#3 corresponds to SSB#0, SSB#1, SSB#2 and SSB#4.
[0470] In order to fully illustrate the scheme of this embodiment, it is assumed that the terminal sends different sequences at three different WUS transmission positions. As can be seen from Figure 4C, when the network device does not receive any WUS signal sent by any terminal, the network device does not need to send SSB; when the network device receives sequence#1 sent by the terminal on resource#1, the network device sends SSB#0; when the network device receives sequence#1 sent by the terminal on resource#1, the network device sends SSB#0; when the network device receives sequence#2 sent by the terminal on resource#1, the network device sends SSB#1; when the network device receives sequence#1 sent by the terminal on resource#2, the network device sends SSB#3; when the network device receives sequence#2 sent by the terminal on resource#2, the network device sends SSB#4; when the network device receives any sequence sent by the terminal on resource#3, the network device sends SSB#0, SSB#1, SSB#2 and SSB#4.
[0471] Optional implementation method 4: As in any embodiment of optional implementation method 1-optional implementation method 3, when the network device configures and activates the cell-specific DTX / DRX pattern, the terminal can still send the first information according to actual needs within the inactive duration. For specific implementation, please refer to the above optional implementation methods 1-optional implementation method 3, which will not be repeated here.
[0472] In some embodiments, after the terminal sends the first information, it can detect and receive the corresponding downlink transmission at the time domain resource location of the first downlink transmission request after the first duration. The first duration is determined according to the terminal's capabilities, or the first duration is determined by configuration information sent by the network device.
[0473] In the embodiment of the present disclosure, the implementation process of the terminal sending the first information and the network device receiving the first information and determining to send the downlink transmission can refer to any embodiment of optional implementation mode 1 to optional implementation mode 3.
[0474] In an embodiment of the present disclosure, when a network device is configured and a cell-specific DTX / DRX pattern is activated, regardless of whether the first time-frequency resource configured by the network device or predefined by the protocol is in the active duration, the terminal can send the first information on the corresponding first time-frequency resource according to its own needs to request the network device to send the corresponding downlink transmission. Referring to Figure 4D, Figure 4D is a schematic diagram of the transmission timing of the first information shown in accordance with an embodiment of the present disclosure. As shown in Figure 4D, when the network device is configured and a cell-specific DTX / DRX pattern is activated, regardless of whether the first time-frequency resource is in the active duration or in the inactive duration, the first information (i.e., the WUS signal) can be sent.
[0475] It should be noted that the communication method provided in the embodiments of the present disclosure can be applied to UEs in any state, including but not limited to CONNECTED UE, IDLE UE and INACTIVE UE.
[0476] In some embodiments, when the first time-frequency resource is determined via RRC signaling and the terminal enters an IDLE state or an INACTIVE state, the relevant configuration may be retained, and the terminal may still send the first information according to the retained configuration. Correspondingly, the network device needs to detect and receive the first information at the corresponding resource location according to the configuration and perform the corresponding action.
[0477] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
