[0002] Unlicensed bands can be used as a supplement to licensed bands to help operators expand communication services. Since unlicensed bands are shared by multiple technologies, such as Wireless Fidelity (WiFi), radar, Long Term Evolution-Licensed Assisted Access (LTE-LAA), etc., for unlicensed spectrum, communication devices (such as network-side devices or terminals) need to detect whether the channel is idle before transmission, that is, listen before talk (LBT). If the channel is idle, transmission can be carried out. Otherwise, it will wait for the next channel detection.

[0003] In addition, transmission on unlicensed frequency bands also needs to meet the requirements of occupied channel bandwidth (OCB), so the transmission on unlicensed frequency bands can be allocated resources in an interlace manner. In order to improve the resource utilization of unlicensed frequency bands, multiple terminals can reuse unlicensed frequency band resources. However, when multiple terminals reuse unlicensed frequency band resources, if a scheduling conflict occurs, the terminal and the network side device will not be able to transmit, resulting in transmission failure.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0037] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0038] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (Vehicle User Equipment, VUE), a pedestrian terminal (Pedestrian User Equipment, PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, wherein the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0039] In the unlicensed frequency band transmission scenario, in order to improve the resource utilization rate of the unlicensed frequency band, the unlicensed frequency band can be shared between the terminal and the base station, and between the terminals. When multiple terminals have scheduling conflicts, these terminals all try to access the channel, which may cause the channel preemption to fail and the terminal cannot transmit. In this regard, the embodiment of the present application provides a method for canceling transmission in an unlicensed frequency band, which will be described below in conjunction with the accompanying drawings.

[0040] like Figure 2 As shown, the method for canceling transmission in an unlicensed frequency band in an embodiment of the present application includes the following steps:

[0041] Step 21: The network side device sends a cancellation indication CI to the terminal.

[0042] Among them, CI is used to instruct the terminal to cancel the previously scheduled transmission, or to indicate that the previously scheduled transmission of the terminal is canceled. Specifically, if the previously scheduled transmission falls within the resource range indicated by CI, the terminal will cancel the previously scheduled transmission or determine that the previously scheduled transmission is canceled. Optionally, the network side device can send CI via downlink control information (Downlink Control Information, DCI), such as through DCI format 2_4 (DCI format 2_4).

[0043] Step 22: The terminal receives the CI.

[0044] Accordingly, the terminal may receive the CI based on the DCI. Optionally, the CI may carry a terminal identifier (UE ID) or a terminal group identifier (UE group ID) to indicate which terminal or terminals cancel transmission within a specified resource range.

[0045] Step 23: The terminal cancels uplink transmission on the target interlace according to the CI.

[0046] The target interleaving is determined according to the CI. Optionally, the CI may carry interleaving indication information to indicate which interleaving the terminal should cancel transmission on. The interleaving indication information includes but is not limited to: a reference time region, a time domain granularity, a reference frequency region, and a frequency domain granularity.

[0047] Optionally, the transmission cancellation method of the embodiment of the present application also includes: the network side device sends the configuration information of the CI through the Radio Resource Control (RRC), and accordingly, the terminal receives the configuration information of the CI through the RRC. The configuration information carries the optional values ​​of at least some parameters in the CI. For example, information such as the reference time area, time domain granularity, reference frequency area, and frequency domain granularity can be configured by the network side device through high-level signaling, such as configuring a set of optional parameter values ​​through RRC, and then indicating which specific interlaced transmission needs to be canceled through the CI carried by the DCI.

[0048] In this way, when multiple terminals have scheduling conflicts, the network side device can instruct the terminal to cancel the transmission on the conflicting resources through CI, thereby ensuring the transmission of a specific terminal on the conflicting resources and ensuring the transmission reliability of the specific terminal. In addition, CI is based on the interlace granularity indication, which does not affect the transmission on other interlaces and can avoid canceling the transmission on non-conflicting interlaces, thereby ensuring the resource utilization of the unlicensed frequency band.

[0049] The following will further illustrate the method for canceling transmission in an unlicensed frequency band in an embodiment of the present application from the terminal side and the network side device side through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0050] like Figure 3 As shown, the method for canceling transmission in an unlicensed frequency band in an embodiment of the present application is applied to a terminal, including:

[0051] Step 31: The terminal obtains a cancellation indication CI.

[0052] CI is used to instruct the terminal to cancel all or part of the previously scheduled transmission. Specifically, if the previously scheduled transmission falls within the resource range indicated by CI, the terminal will cancel all or part of the previously scheduled transmission.

[0053] Optionally, the CI includes at least one of the following parameters: the number of bits included in the CI, a reference time region, a time domain granularity, a reference frequency region, and a frequency domain granularity. In addition, the CI may also include identification information of the terminal, which is used to indicate which terminal cancels the transmission, or to indicate which terminal the transmission is canceled for.

[0054] Step 32: The terminal cancels uplink transmission on the target interlace according to the CI.

[0055] After obtaining the CI, the terminal determines to cancel the uplink transmission on the target interlace based on the target interlace indicated by the CI to avoid affecting the normal transmission of other terminals on the target interlace. Alternatively, the embodiment of the present application can also be applied to cancel the downlink transmission, and cancel the downlink transmission on the target discrete resource according to the CI, that is, based on the target discrete resource indicated by the CI, it is determined that the network side device cancels the downlink transmission on the target discrete resource, thereby avoiding unnecessary data reception and demodulation operations. Optionally, step 32 includes: if the transmission resource of the uplink transmission overlaps with the target interlace indicated by the CI, cancel the uplink transmission on the target interlace. Alternatively, if the transmission resource of the downlink transmission overlaps with the target discrete resource indicated by the CI, exclude the downlink transmission on the target discrete resource during decoding. That is, if part or all of the resources of any RB in any interlace of a terminal overlap with the time-frequency resources indicated by the CI, then the terminal cancels the transmission of the interlace. Specifically, only the transmission on the overlapping part of the resources in the interlace can be canceled, or the transmission on the entire interlace can be canceled, that is, including the non-overlapping part of the interlace. It should be noted that if the resources scheduled by a terminal are cancelled by CI indication, then if a guard band (GuardBand) is configured, the configured GuardBand resources are also cancelled.

[0056] It is worth pointing out that the method for canceling transmission in the embodiment of the present application can be applied to canceling uplink transmission, and can also be applied to canceling downlink transmission. The scheme for canceling downlink transmission is similar to the scheme for canceling uplink transmission. Therefore, the embodiment of the present application only takes the cancellation of uplink transmission as an exemplary explanation. Those skilled in the art can understand that the specific implementation method of canceling downlink transmission can refer to the implementation method of canceling uplink transmission, so it will not be repeated here.

[0057] In an embodiment of the present application, for the authorized frequency band, in order to improve resource utilization, inter-UE multiplexing is introduced. When a scheduling conflict occurs between terminals, the network-side device can instruct certain terminals to cancel the scheduled services for the transmission of the suddenly arriving services with higher priority. The network-side device sends an uplink CI indication via DCI. If the allocated resources of the previously scheduled terminal fall within the time-frequency region indicated by the CI, the terminal will cancel the previously scheduled transmission. Among them, the resources indicated by the CI are based on the resource allocation of a 2D bitmap, for example, 2bit*3bit are used to indicate the time domain resources and frequency domain resources respectively. For the unlicensed frequency band, a CI indication method similar to that of the authorized frequency band can be adopted. Figure 4As shown in the figure, assuming that the subcarrier spacing is 15kHz, if a 2bit*3bit CI indication method is adopted, the area indicated by the CI indicates 2 symbols in the time domain and 3 physical resource blocks (PRB) or resource blocks (RB) in the frequency domain, namely RB1, RB2, RB3. Terminal 1, terminal 2, terminal 3, and terminal 4 schedule 4 interlaces in an interleaved manner. When there is a terminal among the 4 terminals that has a scheduling conflict with other terminals, the network side device can send a CI to instruct the corresponding terminal to cancel transmission. Among them, when at least one RB of the interlace of a terminal overlaps with the resource indicated by the CI, the terminal needs to cancel the transmission on the corresponding interlace.

[0058] like Figure 4 As shown in the figure, if the time-frequency domain granularity indicated by the CI is relatively coarse, for example, the frequency domain granularity is 3 RBs, corresponding to the three interlace terminals 1, 2 or 3 being scheduled for one interlace respectively, as long as a scheduling conflict occurs in one terminal, even if the scheduling of the other two interlaces does not conflict, if the CI indicates cancellation, then these three terminals all need to cancel the transmission, which causes the terminals that do not need to cancel to cancel the scheduled transmission based on the instruction of the CI, resulting in a decrease in resource utilization.

[0059] Since the unlicensed spectrum is usually in units of 20MHz, the available interlace is related to the sub-carrier space (SCS), and different sub-carriers correspond to different interlace numbers. Taking the sub-carrier spacing of 15kHz as an example, there are 10 interlaces in total. If each interlace is to be indicated, the number of indication bits required for the frequency domain granularity indicated by the CI is greater than or equal to 10; taking the sub-carrier spacing of 30kHz as an example, there are 5 interlaces in total. If each interlace is to be indicated, the number of indication bits required for the frequency domain granularity indicated by the CI is greater than or equal to 5.

[0060] Optionally, the number of bits, time domain granularity, and frequency domain granularity included in the CI satisfy one of the following relationships: the number of bits included in the CI is: the product of the time domain granularity and the frequency domain granularity; or, the number of bits included in the CI is: the sum of the time domain granularity and the frequency domain granularity, for example, the cancellation indication in the frequency domain is applied to all time domain symbols. Assume that the number of bits included in the CI is N CI , the number of bits of the time domain granularity is G CI , the number of bits of frequency domain granularity is N BI , then N CI =G CI ×NBI , that is, N BI =N CI / G CI .

[0061] The frequency domain granularity may be configured by the network side device, predefined, or determined according to the number of bits contained in the CI and the time domain granularity. BI Configured by RRC, the number of CI bits is equal to the number of bits in the frequency domain granularity multiplied by the number of bits in the time domain granularity. For 15kHz, 10 bits are used to indicate the canceled interlace in the form of a bitmap; for 30kHz, 5 bits are used to indicate the canceled interlace in the form of a bitmap. Alternatively, N is calculated BI =N CI / G CI , ensure N BI The number of bits is greater than or equal to 10 (15kHz) or 5 (30Khz). For 15kHz, N BI ≥10, N BI The first 10 bits of the most significant bit (MSB) or the least significant bit (LSB) of the signal are used to indicate each interlace in the form of a bitmap. For 30kHz, N BI ≥5, N BI The first 5 bits of the MSB or LSB of the bitmap indicate each interlace.

[0062] The above uses the CI on a resource block set (RB set) as an example. When there are n RB sets that need to cancel transmission, a similar method can be used. Specifically, when a carrier contains multiple resource block sets, the step of obtaining the cancellation indication CI includes: obtaining the CI corresponding to each of the multiple resource block sets; according to the CI, the step of canceling the uplink transmission on the target interlace includes: according to the CI corresponding to each resource block set, canceling the uplink transmission on the corresponding target interlace. That is to say, when there are n RB sets that need to be canceled, the DCI carrying the CI contains cancellation indication information for each RB set.

[0063] Assume that the CIs of N carriers are indicated by the same DCI, such as Figure 5 As shown, the DCI carrying CI includes CIs of N carriers, one carrier has n RB sets, and the CI corresponding to one carrier includes n CIs indicating RB sets, such as N_1, ..., N_n can represent CIs of n RB sets.

[0064] Alternatively, in the case where a carrier includes at least one resource block set, the step of obtaining a cancellation indication CI includes: obtaining a reference CI corresponding to the at least one resource block set; and the step of canceling the uplink transmission on the target interlace according to the CI includes: canceling the uplink transmission on the corresponding target interlace according to the reference CI. That is, when there are N RB sets that need to be indicated for cancellation, the DCI carrying the CI only includes cancellation indication information of one reference RB set, and the cancellation indication of the reference RB set is used for all RB sets. If a terminal detects that the CI information of the reference RB set overlaps with its scheduled interlace, the terminal will cancel the scheduled uplink transmission.

[0065] Assume that the CIs of N carriers are indicated by the same DCI, such as Figure 6 As shown, the DCI carrying CI contains CIs of N carriers, and one carrier has n RB sets, corresponding to the CI of one carrier including CI of 1 RB set reference. If a terminal receives a CI indication, and any interlace scheduled by the terminal overlaps with any interlace in the RB set reference indicated by the CI, the terminal will cancel the corresponding transmission. The RB set reference may not be an actual RB set, and the cancellation indication of the RBset may be considered valid for any RB set on a carrier or BWP.

[0066] Furthermore, the CI indication may include not only the RB set reference but also the RB set indication to indicate which RB sets the CI is applied to. Figure 7 As shown, the DCI carrying CI contains CIs of N carriers, and one carrier has n RB sets. The CI corresponding to one carrier includes a CI for 1 RB set reference and an RB set indication indicating which RB sets the CI is valid for. Assuming that the network-side device is configured with 5 RB sets, the CI includes a 5-bit RB set indication field to indicate the scope of the cancellation indication, that is, which RB sets are valid. For example, if the RB set indication field is 00101, the cancellation indication applies to the third and fifth RB sets. If the resources scheduled by the terminal overlap with the resources corresponding to the third or fifth RB set, the transmission will be canceled.

[0067] Furthermore, the CI may also include only an RB set indication to indicate which RB sets the cancellation indication is for. Figure 8As shown, the DCI carrying CI contains CIs of N carriers, and one carrier has n RB sets. The CI corresponding to one carrier includes an RB set indication indicating which RB sets the CI is effective in. Assuming that the network side device is configured with 5 RB sets, the CI includes a 5-bit RB set indication field to indicate the scope of the cancellation indication, that is, which RB sets are effective. For example, if the RB set indication field is 00101, the cancellation indication is effective for the third and fifth RB sets. If the terminal is scheduled on the third or fifth RB set, the transmission will be canceled.

[0068] In this way, the terminal can cancel the transmission on the target interlace in the unlicensed frequency band according to the CI, which can avoid the problem of transmission failure caused by scheduling conflicts in the unlicensed frequency band, and improve the service transmission reliability of the unlicensed frequency band. In addition, the CI of the embodiment of the present application is for interlace. When the CI is obtained, it is only necessary to cancel the uplink transmission on the target interlace indicated by the CI, without canceling the uplink transmission on the entire block of resources. This can improve the resource utilization of the unlicensed frequency band.

[0069] The above describes the method for canceling transmission in the present application from the terminal side. The following will further illustrate the method for canceling transmission from the network side device in conjunction with the accompanying drawings.

[0070] like Fig. 9 As shown, the embodiment of the present application provides a method for canceling transmission, comprising the following steps:

[0071] Step 91: The network side device sends a cancellation indication CI, where the CI is used to indicate the cancellation of the target interleaving of uplink transmission.

[0072] Among them, CI is used to instruct the terminal to cancel the previously scheduled transmission, or to indicate that the previously scheduled transmission of the terminal is canceled. Optionally, the network side device can send CI through DCI. Among them, CI includes at least one of the following parameters: the number of bits contained in CI, the reference time area, the time domain granularity, the reference frequency area, and the frequency domain granularity. In addition, CI may also include the identification information of the terminal, which is used to indicate which terminal cancels the transmission, or to indicate which terminal the transmission is canceled.

[0073] Optionally, the transmission cancellation method of the embodiment of the present application further includes: the network side device sends configuration information of CI through RRC, and the configuration information carries optional values ​​of at least some parameters in CI. For example, information such as reference time area, time domain granularity, reference frequency area, and frequency domain granularity can be configured by the network side device through high-level signaling, such as configuring a set of parameter optional values ​​through RRC, and then indicating which specific interlaced transmission needs to be canceled through the CI carried by DCI.

[0074] Furthermore, the number of bits, time domain granularity, and frequency domain granularity contained in the CI satisfy one of the following relationships: the number of bits contained in the CI is: the product of the time domain granularity and the frequency domain granularity; the number of bits contained in the CI is: the sum of the time domain granularity and the frequency domain granularity. The frequency domain granularity can be configured by the network side device, predefined, or determined based on the number of bits contained in the CI and the time domain granularity. The specific determination method can refer to the above-mentioned terminal side embodiment, so it will not be repeated here.

[0075] Optionally, step 91 may include: before uplink transmission, sending CI to ensure that the terminal receives CI indicating cancellation of uplink transmission before uplink transmission, so as to cancel the uplink transmission in time and ensure transmission of other terminals.

[0076] In this way, the network side device sends CI to instruct the terminal to cancel the uplink transmission on the target interlace. The terminal can cancel the transmission on the target interlace in the unlicensed frequency band according to CI, thereby avoiding the problem of transmission failure caused by scheduling conflicts in the unlicensed frequency band, and improving the service transmission reliability of the unlicensed frequency band. In addition, the CI of the embodiment of the present application is for interlace. When the CI is obtained, it is only necessary to cancel the uplink transmission on the target interlace indicated by the CI, without canceling the uplink transmission on the entire block of resources. This can improve the resource utilization rate of the unlicensed frequency band.

[0077] It should be noted that the method for canceling transmission provided in the embodiment of the present application can be executed by a device for canceling transmission in an unlicensed frequency band, or a control module in the device for canceling transmission in an unlicensed frequency band for executing the method for canceling transmission in an unlicensed frequency band.
