[0043] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0044] Unlicensed spectrum is a spectrum that can be used for radio equipment communication divided by countries and regions. This spectrum is generally considered to be a shared spectrum, that is, as long as the communication equipment in different communication systems meets the regulatory requirements set by the country or region on the spectrum, they can use the spectrum without applying for exclusive spectrum authorization from the government. In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist in a friendly manner on the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, in some regions, communication equipment follows the "Listen Before Talk (LBT)" principle, that is, before the communication equipment sends a signal on the channel of the unlicensed spectrum, it needs to first perform channel sensing. Only when the channel sensing result is that the channel is idle, the communication equipment can send a signal; if the channel sensing result of the communication equipment on the channel of the unlicensed spectrum is that the channel is busy, the communication equipment cannot send a signal. In order to ensure fairness, in one transmission, the duration of the communication equipment using the channel of the unlicensed spectrum for signal transmission cannot exceed MCOT. With the development of wireless communication technology, both LTE systems and NR systems will consider deploying networks on unlicensed spectrum to use unlicensed spectrum to transmit data services.

[0045] Figure 2 A schematic diagram of transmitting data on an unlicensed spectrum is given. If the pre-configured (Configured grant) first transmission resource is within the MCOT, the terminal device can transmit an uplink signal through the first transmission resource of the Configured grant. If the second transmission resource of the Configured grant is outside the MCOT, the terminal device cannot transmit an uplink signal through the second transmission resource of the Configured grant. If part of the third transmission resource of the Configured grant is within the MCOT and the other part is outside the MCOT, it is not clear whether the third transmission resource can be used for signal transmission and how to use the third transmission resource for signal transmission. For this reason, the following technical solution of an embodiment of the present application is proposed. An embodiment of the present application provides a transmission resource determination method, which is suitable for unlicensed frequency band transmission scenarios.

[0046] Figure 3 Schematic diagram of the process of the transmission resource determination method provided in the embodiment of the present application Figure 1 ,like Figure 3 As shown, the transmission resource determination method includes the following steps:

[0047] Step 301: A first device obtains resource configuration information, wherein a portion of a time domain of a first transmission resource configured by the resource configuration information is located within the COT, and another portion is located outside the COT.

[0048] In the embodiment of the present application, the resource configuration information is pre-configured, semi-statically scheduled or dynamically scheduled. Specifically, the first device can determine the first transmission resource in any of the following ways:

[0049] 1) The first device determines a first transmission resource according to pre-configured resource configuration information.

[0050] This method is applicable to the scenario of pre-scheduled transmission, and the first transmission resource is, for example, the transmission resource of the Configured Grant. For example: before the first device transmits a signal, the network side pre-configures all the contents of the resource configuration information (such as frequency domain resources, period of time domain resources, location of time domain resources, modulation and coding method, etc.) for the first device through RRC signaling.

[0051] 2) The first device determines a first transmission resource according to resource configuration information of semi-static scheduling.

[0052] This method is applicable to the scenario of pre-scheduled transmission, and the first transmission resource is, for example, a transmission resource of semi-persistent scheduling (SPS). For example: before the first device transmits a signal, the network side pre-configures part of the resource configuration information (such as frequency domain resources, period of time domain resources, modulation coding method, etc.) for the first device through RRC signaling; when the first device needs to transmit a signal, the network side activates the resource configuration information and configures another part of the resource configuration information (such as the location of time domain resources) through downlink control information (Downlink Control Information, DCI).

[0053] 3) The first device determines a first transmission resource according to dynamically scheduled resource configuration information.

[0054] This method is applicable to the scenario of dynamically scheduled transmission, where the first transmission resource is, for example, a transmission resource scheduled by a downlink grant (DL grant) or an uplink grant (UL grant). For example: when the first device needs to transmit a signal, the network side configures all the contents of the resource configuration information (such as frequency domain resources, time domain resources, modulation and coding methods, etc.) through DCI.

[0055] In the embodiment of the present application, the first transmission resource crosses the COT boundary. Specifically, a portion of the first transmission resource is located within the COT, and another portion is located outside the COT.

[0056] It should be noted that the COT in the embodiment of the present application may refer to the MCOT.

[0057] It should be noted that the COT in the embodiment of the present application may refer to a shared COT or a dedicated COT. A shared COT means that the COT can be used for both uplink transmission and downlink transmission. A dedicated COT means that the COT is only used for uplink transmission or only for downlink transmission.

[0058] Step 302: The first device determines not to transmit a signal on the first transmission resource or to transmit a signal on a second transmission resource, wherein all or part of the second transmission resource is a portion of the transmission resource of the first transmission resource that is located within the COT in the time domain.

[0059] In an embodiment of the present application, optionally, the second transmission resource does not include a portion of the first transmission resource whose time domain is outside the COT.

[0060] In the embodiment of the present application, the first transmission resource has the following implementation methods for whether the first transmission resource can be used to transmit signals and how to transmit signals.

[0061] ●Method 1: The first device does not transmit signals on the first transmission resource.

[0062] By adopting the above-mentioned method 1, for the first transmission resource across the COT boundary, the terminal device does not transmit signals on the first transmission resource, which is simple to implement.

[0063] ● Mode 2: The first device transmits a signal on a second transmission resource, wherein all or part of the second transmission resource is a portion of the transmission resource of the first transmission resource that is located within the COT in the time domain.

[0064] Here, the first device transmits a signal on a portion of the transmission resources (ie, the second transmission resources) located within the COT in the first transmission resource time domain. The following describes how to determine the second transmission resources.

[0065] A) The first transmission resource configured by the resource configuration information is used for transmission of at least one channel; if all of N channels in the at least one channel are within the COT, then the second transmission resource is the transmission resource corresponding to the N channels, and N is a positive integer.

[0066] B) The first transmission resource configured by the resource configuration information is used for transmission of at least one channel; part of N channels in the at least one channel is within the COT, then the second transmission resource is the transmission resource corresponding to the N channels in the at least one channel and located within the COT, and N is a positive integer.

[0067] In an optional manner, a first sub-portion of a first channel in the at least one channel is within the COT, and a second sub-portion of the first channel is outside the COT. That is, the first channel in the at least one channel is a channel across the COT boundary. For the first channel, the first device may transmit the first channel in the following manner:

[0068] I) The first device maps all transport blocks (TBs) corresponding to the first channel to a first target resource according to a first coding rate, and transmits all TBs corresponding to the first channel through the first target resource (i.e., transmits the signal on the first target resource); wherein the first target resource is a transmission resource corresponding to a first sub-part of the first channel. Or,

[0069] II) The first device maps all TBs corresponding to the first channel to the second target resource according to the second coding rate, and transmits part of the TBs corresponding to the first channel through the transmission resources in the second target resource that are located within the COT in the time domain (i.e., only transmits the signals on the transmission resources in the second target resource that are located within the COT in the time domain); wherein the second target resource is the transmission resource corresponding to the first channel.

[0070] In an optional manner, the first device transmits a signal on the second transmission resource using a first transmission mode. Further, optionally, the first transmission mode is determined based on preconfigured scheduling information; or, the first transmission mode is determined based on preconfigured scheduling information, the first transmission resource, and the second transmission resource.

[0071] Here, optionally, the first transmission mode is, for example, a modulation and coding scheme (MCS).

[0072] For example: when a first MCS is indicated in the pre-configured scheduling information, the first transmission mode may be the first MCS.

[0073] For example: when the first MCS is indicated in the preconfigured scheduling information, the first transmission mode may be a second MCS determined based on the first MCS, the first transmission resource, and the second transmission resource. For example: if the first transmission resource is 14 symbols and the second transmission resource is 7 symbols, the coderate of the second MCS is 1 / 2 of the coderate of the first MCS.

[0074] C) The first transmission resource configured by the resource configuration information is used for transmission of at least one channel; if all of N channels in the at least one channel are within the COT, then the first part of the second transmission resource is the transmission resource occupied by N channels in the at least one channel, and the second part of the second transmission resource is obtained by LBT or preemption based on frame structure (Frame Based Equipment, FBE), and N is a positive integer.

[0075] In an optional manner, the first device transmits N channels of the at least one channel on a first part of the second transmission resources; and the first device transmits channels of the at least one channel other than the N channels on a second part of the second transmission resources.

[0076] In the above scheme, optionally, the preemption level of the LBT or FBE is a specified priority (eg, the highest priority); or, the preemption level of the LBT or FBE is the priority corresponding to the signal to be transmitted.

[0077] In an optional manner, the execution start time of the LBT or FBE is the end time of the COT. In another optional manner, the execution start time of the LBT or FBE is the first time after the end time of the COT. Further, optionally, the time interval between the first time and the end time of the COT is a fixed interval or a random interval.

[0078] By adopting A) and B) in the above-mentioned method 2, for the first transmission resource across the COT boundary, the terminal device only occupies the resources within the MCOT to transmit the signal, which can make full use of the existing resources and avoid the delay and complexity caused by resource preemption.

[0079] Using C) in the above-mentioned method 2, for the first transmission resource across the COT boundary, the first transmission resource is divided into two parts. The first part is the resources occupied within the COT, and the second part is the resources obtained through LBT or FBE preemption, so as to maximize the signal transmission and ensure the integrity and reliability of the signal transmission.

[0080] It should be noted that the transmission resources in the above scheme of the embodiment of the present application mainly refer to time domain resources.

[0081] It should be noted that the N channels in the above scheme of the embodiment of the present application are used to transmit the same TB (that is, the N channels can be repeated transmissions for the same TB); or, the N channels are used to transmit multiple independent TBs (that is, the N channels can be transmissions for multiple independent TBs).

[0082] In an optional manner, the technical solution of the embodiment of the present application can be applied to uplink transmission, and accordingly, the first device is a terminal device, and the channel is a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or a physical uplink control channel (Physical Uplink Control Channel, PUCCH).

[0083] In another optional embodiment, the technical solution of the embodiment of the present application can be applied to downlink transmission, and accordingly, the first device is a network device, and the channel is a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) or a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

[0084] It should be noted that the technical solution of the embodiment of the present application is applicable to data transmission, and accordingly, the signal in the above solution is data, and the channel in the above solution is PUSCH or PDSCH. The technical solution of the embodiment of the present application is also applicable to control signaling transmission, and accordingly, the signal in the above solution is control signaling, and the channel in the above solution is PUCCH or PDCCH.

[0085] In specific implementation, different channels (or different signals) can use different transmission methods. For example, the transmission of PUCCH (or uplink control signaling) adopts method 1 in the above scheme, so that the transmission quality can be guaranteed first. The transmission of PUSCH (or uplink data) adopts method 2 in the above scheme, so as to give priority to low transmission delay.

[0086] The following is an example of the technical solution of the embodiment of the present application in conjunction with a specific application example. It should be noted that the following example is an example of the first device being a terminal device, the signal being uplink data, and the channel being PUSCH. It should be understood that the technical solution of the embodiment of the present application can also be applied to the network device side, the signal being downlink data or downlink control signaling, and the channel being PDSCH or PDCCH.

[0087] Example 1

[0088] Figure 4 Schematic diagram of the process of the transmission resource determination method provided in the embodiment of the present application Figure 2 ,like Figure 4 As shown, the transmission resource determination method includes the following steps:

[0089] Step 401: The terminal device determines a first transmission resource.

[0090] In one optional manner, the terminal device determines the first transmission resource according to the resource configuration information of the Configured grant. In another optional manner, the terminal device determines a part of the configuration of the first transmission resource (such as the period of the time domain resource, etc.) according to the resource configuration information of the Configured grant, the terminal device receives a DCI, the DCI is used to activate the Type2Configured grant, and the terminal device determines another part of the configuration of the first transmission resource (such as the location of the time domain resource) according to the Time Domain ResourceAllocation (TDRA) field in the DCI.

[0091] Step 402: The terminal device determines whether to transmit uplink data on the first transmission resource.

[0092] Specifically, if the first transmission resource is completely contained in the MCOT, the terminal device can transmit uplink data on the first transmission resource.

[0093] If the first transmission resource is not completely contained in the MCOT, the terminal device does not transmit uplink data on the first transmission resource, referring to Figure 5 Specifically, the first transmission resource is used for transmission of at least one PUSCH, wherein if any one of the at least one PUSCH is partially or completely located outside the MCOT, the terminal device does not transmit uplink data on the first transmission resource. Further, optionally, the terminal device can transmit the PUSCH by re-seizing the resource.

[0094] Example 2

[0095] Figure 6 Schematic diagram of the process of the transmission resource determination method provided in the embodiment of the present application Figure 3 ,like Figure 6 As shown, the transmission resource determination method includes the following steps:

[0096] Step 601: The terminal device determines a first transmission resource, and determines a second transmission resource in the first transmission resource.

[0097] In one optional manner, the terminal device determines the first transmission resource according to the resource configuration information of the Configured grant. In another optional manner, the terminal device determines a part of the configuration of the first transmission resource (such as the period of the time domain resource, etc.) according to the resource configuration information of the Configured grant, the terminal device receives a DCI, the DCI is used to activate the Type2Configured grant, and the terminal device determines another part of the configuration of the first transmission resource (such as the position of the time domain resource) according to the TDRA field in the DCI.

[0098] In this example, the terminal device can determine the second transmission resource in the first transmission resource according to the following method.

[0099] A) If the first transmission resource is completely contained in the MCOT, then the second transmission resource is the first transmission resource.

[0100] B) If the first transmission resource is not completely contained in the MCOT, then:

[0101] b1) The first transmission resource is used for transmission of at least one PUSCH, wherein N PUSCHs in the at least one PUSCH are all within the MCOT, and the second transmission resource is the resource occupied by N PUSCHs in the at least one PUSCH, where N is a positive integer, refer to Figure 7 (a) and (b) in . Optionally, the N PUSCHs are applicable to a scenario of PUSCH repetition transmission, that is, the N PUSCHs are used to transmit the same TB or the N PUSCHs can be repeated transmissions for the same TB. Not limited to this, the N PUSCHs can also be used to transmit multiple independent TBs.

[0102] b2) The first transmission resource is used for transmission of at least one PUSCH, wherein N PUSCHs in the at least one PUSCH are partially or entirely within the MCOT, and the second transmission resource is the resource within the MCOT occupied by the N PUSCHs in the at least one PUSCH, where N is a positive integer, refer to Figure 7 (a) and (c) in . The PUSCH (i.e., the first channel) that crosses the MCOT boundary is split. The splitting methods include: I) the TB remains unchanged, and the TB corresponding to the PUSCH is mapped to (i.e., adapted to) the available resources within the MCOT (i.e., the resources of the PUSCH within the MCOT) according to the modified coding rate (coderate). Or, II) the TB remains unchanged, and the TB corresponding to the PUSCH is mapped to (i.e., adapted to) the resources corresponding to the PUSCH according to the configured coderate, and then the PUSCH is punctured to only transmit the uplink data of the PUSCH on the resources within the MCOT. Optionally, the N PUSCHs are suitable for the scenario of PUSCH repetition transmission, that is, the N PUSCHs are used to transmit the same TB or the N PUSCHs can be repeated transmissions for the same TB. Not limited to this, the N PUSCHs can also be used to transmit multiple independent TBs.

[0103] Step 602: The terminal device transmits uplink data on the second transmission resource.

[0104] In an optional manner, the terminal device determines the first transmission mode according to the scheduling information of the Configured grant, for example, the terminal device determines the first MCS according to the Modulation and Coding Scheme (MCS) field in the DCI, and the DCI is used to activate the Type 2 Configured grant. The terminal device uses the first MCS to transmit uplink data on the second transmission resource.

[0105] In another optional manner, the terminal device determines the first transmission mode according to the scheduling information of the Configured grant, the first transmission resource and the second transmission resource. For example, the terminal device determines the first MCS according to the MCS field in the DCI (the DCI is used to activate the Type2Configured grant), and determines the second MCS according to the first MCS, the first transmission resource and the second transmission resource. The terminal device uses the second MCS to transmit uplink data on the second transmission resource. For example: the first transmission resource is 14 symbols and the second transmission resource is 7 symbols, then the coderate of the second MCS is 1 / 2 of the coderate of the first MCS, and occupies more frequency domain resources.

[0106] Example 3

[0107] Figure 8 Schematic diagram of the process of the transmission resource determination method provided in the embodiment of the present application Figure 4 ,like Figure 8 As shown, the transmission resource determination method includes the following steps:

[0108] Step 801: The terminal device determines a first transmission resource and determines a second transmission resource.

[0109] In one optional manner, the terminal device determines the first transmission resource according to the resource configuration information of the Configured grant. In another optional manner, the terminal device determines a part of the configuration of the first transmission resource (such as the period of the time domain resource, etc.) according to the resource configuration information of the Configured grant, the terminal device receives a DCI, the DCI is used to activate the Type2Configured grant, and the terminal device determines another part of the configuration of the first transmission resource (such as the position of the time domain resource) according to the TDRA field in the DCI.

[0110] In this example, the terminal device can determine the second transmission resource in the first transmission resource according to the following method.

[0111] A) If the first transmission resource is completely contained in the MCOT, the first part of the second transmission resource is the first transmission resource, and the second part of the second transmission resource is empty.

[0112] B) If the first transmission resource is not completely contained in the MCOT, then:

[0113] The first transmission resource is used for the transmission of at least one PUSCH, wherein N PUSCHs in the at least one PUSCH are all within the MCOT, then the first part of the second transmission resource is the resource occupied by N PUSCHs in the at least one PUSCH, N is a positive integer; the second part of the second transmission resource is obtained by LBT or FBE preemption, refer to Fig. 9 Optionally, the preemption level of LBT or FBE may adopt the highest priority, or adopt the priority corresponding to the uplink data to be transmitted.
