Description

[0001] This application claims the priority of a Chinese patent application with the application number 202010525719.2 and the application title "A Method and UE for Providing Auxiliary Information" filed with the National Intellectual Property Administration on June 10, 2020, the entire content of which is incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly, to a method and apparatus for determining resources in the field of communications. Background Art

[0003] A traditional cell consists of a downlink carrier and an uplink carrier. The base station sends downlink signals to the terminal through the downlink carrier, and the terminal sends uplink signals to the base station through the uplink carrier. When the cell is a time division duplex (TDD) cell, the uplink carrier and the downlink carrier use the same frequency; when the cell is a frequency division duplex (FDD) cell, the uplink carrier and the downlink carrier use two separate frequencies with a certain frequency interval between them. TDD represents time division duplex, which means that the uplink and downlink are multiplexed according to different time domain resources on the same frequency band; FDD represents frequency division duplex, where the uplink and downlink are multiplexed in different frequency bands.

[0004] In the initial stage of the deployment of the fifth generation (5G) mobile communication system, the frequency band used is higher than that of the fourth generation (4G) mobile communication system. For example, 5G is deployed in the 3.5 gigahertz (GHz) frequency band. Due to the electromagnetic wave characteristic that the higher the frequency, the greater the attenuation, and the transmit power of the terminal is lower than that of the base station, the terminal at the edge of the cell can receive the downlink signal from the base station, but the base station cannot receive the uplink signal from the terminal, resulting in a smaller uplink coverage range than the downlink coverage range.

[0005] To improve the uplink coverage of a 5G cell, one or more additional lower-frequency uplink carriers can be introduced outside the original uplink carrier of the cell to send uplink signals. We can call this lower-frequency uplink carrier the "supplemental uplink (SUL) band", "SUL carrier", or "SUL resource". By performing uplink transmission through the time domain resources provided by this SUL carrier, the coverage of the cell edge scenario can be improved.

[0006] In the existing spectrum planning, it is difficult to obtain SUL spectrum resources. There is no dedicated frequency band that can be used as SUL resources and only supports uplink transmission. In addition, with the development of diversified services in 5G, SUL needs to meet not only the requirements of uplink coverage but also the requirements of uplink capacity improvement. Therefore, more SUL resources need to be provided. To sum up, how to deploy SUL resources more effectively and flexibly, and how to use SUL to improve the uplink coverage is an urgent problem to be solved. Summary of the Invention

[0007] This application provides a method and apparatus for determining resources. This method can configure the time-domain resources of the SUL carrier, so that the SUL transmission is not affected by services such as the downlink transmission of the SUL carrier, and the reliability of the transmission and the capacity of the uplink transmission are improved.

[0008] In a first aspect, a method for determining resources is provided, including: sending first indication information to a terminal device, where the first indication information is used to indicate M time-domain resources of a first uplink carrier, where the first uplink carrier supports secondary uplink SUL transmission, and the M time-domain resources are the time-domain resources for SUL transmission among the N time-domain resources included in the first uplink carrier, the N time-domain resources include uplink resources and / or flexible time-domain resources, the time-domain resources include time slots and / or symbols, and M < N; receiving a first uplink signal and / or an uplink channel through the M time-domain resources of the first uplink carrier.

[0009] Optionally, in the embodiment of this application, the case of M = N may also be included. It should be understood that in the prior art, a dedicated SUL carrier is set, and all uplink resources of the SUL carrier are used for uplink transmission. Through the method provided in the embodiment of this application, all or part of the time-domain resources of the SUL carrier can be configured to send uplink signals / uplink channels. Or, within a period of time, all the time-domain resources of the SUL carrier are configured to be used for uplink transmission. Compared with the case where all the time-domain resources of the SUL carrier are used for uplink transmission at any time, the configuration method is more flexible and the resource utilization rate is higher.

[0010] Through the above technical solutions, the embodiment of this application can configure the available time-domain resources of one or more SUL carriers. When the frequency band where the SUL carrier is located multiplexes the TDD frequency band or the low-frequency FDD frequency band, some time-domain resources of the SUL carrier may support some downlink transmissions. The embodiment of this application configures the available time-domain resources for uplink transmission of the SUL carrier, so that the SUL transmission is not affected by services such as the downlink transmission of the SUL carrier, improves the reliability of the transmission, and further improves the capacity of the uplink transmission. In addition, part of the time-domain resources of the one or more SUL carriers can be configured to be dynamic or semi-static for other services, which can improve the resource utilization efficiency.

[0011] It should be understood that in the embodiments of the present application, the first uplink carrier may also be referred to as the "SUL carrier", and one or more first uplink carriers may be included in the system, that is, one or more SUL carriers are included. In the embodiments of the present application, a method for configuring available resources of the SUL carrier will be described by taking one SUL carrier as an example, and the number of SUL carriers (the first uplink carriers) in the embodiments of the present application is not limited.

[0012] In a possible scenario, the base station may provide carriers for multiple terminal devices. For example, the base station may provide an NR carrier for the first terminal device for the uplink transmission and downlink transmission (NUL and NDL) of the terminal device; in addition, the base station may also provide an LTE carrier for the second terminal device for the uplink transmission and downlink transmission (NUL and NDL) of the second terminal device. Optionally, the frequency point of the NR carrier of the first terminal device may be higher than the frequency point of the LTE carrier of the second terminal device. In this scenario, in combination with the embodiments of the present application, the SUL carrier of the first terminal device may reuse the LTE carrier in the lower frequency band of the second terminal device.

[0013] Alternatively, in another possible scenario, both the first terminal device and the second terminal device may be terminal devices operating in NR, and the base station provides NR carriers for the first terminal device and the second terminal device respectively. Optionally, the frequency band range of the NR carrier of the first terminal device may be different from the frequency band range of the NR carrier of the second terminal device. In this scenario, in combination with the embodiments of the present application, the SUL carrier of the first terminal device may reuse the NR carrier in the lower frequency band of the second terminal device, or the SUL carrier of the second terminal device may reuse the NR carrier in the lower frequency band of the first terminal device. It should be understood that the embodiments of the present application do not limit the available scenarios.

[0014] Optionally, the frequency band where the SUL carrier is located may reuse the TDD frequency band of LTE or the low-frequency FDD frequency band deployed by NR. Specifically, the available SUL carrier may be configured for the terminal device by the base station, or the SUL carrier associated with the NDL / NUL frequency band of the terminal device may be predefined, etc. There are many possible ways, and this method is described in detail in other related patent applications, and the embodiments of the present application will not elaborate on this.

[0015] It should also be understood that in the embodiments of the present application, the first uplink carrier supporting the supplementary uplink SUL transmission may include N time-domain resources, and the time-domain resources may specifically refer to the "time slot" and / or "time-domain symbol" introduced above.

[0016] Optionally, among the N time-domain resources of the first uplink carrier, one or more of the time-domain resources configured for uplink transmission (labeled as "U"), flexible time-domain resources (flexible, labeled as "F"), and unavailable time-domain resources (labeled as "D") may be included.

[0017] The method provided by the embodiments of this application may configure the time slots and / or symbols for transmitting uplink signals and / or uplink channels on one or more SUL carriers, or configure the number of time slots or symbols for transmitting the first uplink signal and / or uplink channel on the SUL carrier. The embodiments of this application do not limit this.

[0018] In a possible implementation, the base station may only tell the terminal device the information of the M time-domain resources through the first indication information, such as the location, quantity, etc. of the M time-domain resources. The terminal device can determine the time-domain resources for transmitting the first uplink signal and / or uplink channel based on the location and quantity information of the M time-domain resources indicated by the first indication information.

[0019] Combined with the first aspect, in some possible implementations, when the N time-domain resources include flexible time-domain resources, the first indication information is further used to indicate K of the flexible time-domain resources, where the flexible time-domain resources are used for SUL transmission or downlink transmission, K < N; and receiving the first uplink signal and / or uplink channel through the M time-domain resources of the first uplink carrier includes: receiving the first uplink signal and / or uplink channel through the M time-domain resources and the K flexible time-domain resources of the first uplink carrier.

[0020] Combined with the first aspect and the above implementations, in some possible implementations, the first indication information is carried in the system information block SIB; or the first indication information is carried in the downlink control information DCI; or the first indication information is carried in the radio resource control RRC dedicated signaling.

[0021] It should be understood that the base station may send the first indication information to the terminal device in different ways, that is, the first indication information may be carried in different messages.

[0022] Combined with the first aspect and the above implementations, in some possible implementations, the frequency band where the first uplink carrier is located further includes other resources for downlink transmission, and the frequency band where the first uplink carrier is located is a TDD frequency band.

[0023] It should be understood that the frequency band where the first uplink carrier in the embodiments of the present application is located is a TDD frequency band, and the frequency band where the first uplink carrier is located further includes other resources for downlink transmission. In other words, one or more SUL carriers in the embodiments of the present application multiplex the existing TDD frequency band of LTE or the low-frequency FDD frequency band of NR deployment, and the one or more SUL carriers are different from the dedicated SUL carriers configured in the prior art. Specifically, any resource in the dedicated SUL carrier configured in the prior art can be used for uplink transmission, that is, to send PUCCH / PUSCH.

[0024] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the time slots and / or symbols used by the first uplink carrier are configured as a subset of the uplink time slots and / or symbols and flexible time slots and / or symbols to which the frequency band where the first uplink carrier is located belongs; or the time slots and / or symbols used by the first uplink carrier are configured as a subset of the uplink time slots and / or symbols or flexible time slots and / or symbols to which the frequency band where the first uplink carrier is located belongs.

[0025] It should be understood that the "subset" here may include configuring the time slots of the SUL carrier according to the same number of uplink time slots and / or flexible time slots, or configuring the symbols of the SUL carrier according to the same number of uplink symbols and / or flexible symbols. Or, configuring the time slots of the SUL carrier according to a number of uplink time slots and / or flexible time slots less than that included in the frequency band where the SUL carrier is located, or configuring the symbols of the SUL carrier according to a number of uplink symbols and / or flexible symbols less than that included in the frequency band where the SUL carrier is located. The embodiments of the present application do not limit this.

[0026] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when the N time domain resources include K flexible time domain resources, the method further includes: sending second indication information to the terminal device, where the second indication information is used to indicate L time domain resources used for SUL transmission among the K flexible time domain resources, where the L time domain resources include L0 uplink resources and L1 flexible time domain resources, 0≤L≤K, and receiving a first uplink signal and / or an uplink channel through M time domain resources of the first uplink carrier, including: receiving the first uplink signal and / or the uplink channel through the M time domain resources and the L time domain resources of the first uplink carrier.

[0027] It should be understood that the L time domain resources here may include L0 uplink resources and L1 flexible time domain resources. In other words, the L time domain resources here may include L0 resources configured as "U" and L1 flexible time domain resources configured as "F".

[0028] It should also be understood that after the base station configures the time-domain resources of one or more SUL carriers for the terminal device, it can also modify the K flexible time-domain resources of the one or more already-configured SUL carriers according to different scenarios and requirements, that is, modify the configuration of the flexible time-domain resources through the second indication information provided in the embodiments of the present application.

[0029] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the second indication information is carried in the Radio Resource Control (RRC) dedicated signaling; or the second indication information is carried in the Downlink Control Information (DCI).

[0030] Optionally, when the first indication information is sent through the SIB, the second indication information may be carried in the RRC dedicated signaling. Specifically, the configuration of the flexible time-domain resources of the SUL carrier is further modified through the RRC dedicated signaling.

[0031] Or, when the first indication information is sent through the SIB, the second indication information may also be carried in the DCI or MAC CE. Specifically, the above implementation manner sends the second indication information to the terminal device through the DCI or MAC CE to further modify the flexible time-domain resource F configured in the first indication information.

[0032] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: sending a third indication information to the terminal device, where the third indication information is used to indicate S time-domain resources for uplink transmission among the L1 flexible time-domain resources, 0≤S≤L1; and receiving a first uplink signal and / or an uplink channel through M time-domain resources of the first uplink carrier, including: receiving the first uplink signal and / or the uplink channel through M time-domain resources, L0 uplink resources, and S time-domain resources of the first uplink carrier.

[0033] It should be understood that the S time-domain resources may include S0 uplink resources and S1 flexible time-domain resources. In other words, the S time-domain resources may include S0 resources configured as "U" and S1 flexible time-domain resources configured as "F".

[0034] It should also be understood that the base station can also modify the L1 flexible time-domain resources of the one or more already-configured SUL carriers according to different scenarios and requirements, that is, modify the configuration of the flexible time-domain resources through the third indication information provided in the embodiments of the present application.

[0035] Exemplarily, the base station first sends the first indication information to the terminal device, configuring the time-domain resources of one or more SUL carriers; then sends the second indication information to the terminal device. After modifying the flexible time-domain resources of one or more SUL carriers, the flexible time-domain resources of the one or more configured SUL carriers can be further modified, that is, modified through the third indication information provided in the embodiments of the present application.

[0036] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the third indication information is carried in the downlink control information DCI, and the DCI is used to indicate one or more of the first uplink carriers for SUL transmission.

[0037] Optionally, the DCI or the MAC CE can further configure the specified time slots and / or symbols on the SUL carrier as the time-domain resources for sending the first uplink signal / channel. Exemplarily, the DCI or the MAC CE may include the third indication information for re-indicating the configuration of the flexible time-domain resources of the SUL carrier within a certain period.

[0038] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when indicating n of the first uplink carriers through the downlink control information DCI, the DCI specifically indicates multiple groups of time slot configuration sets, and the multiple groups of time slot configuration sets are used to configure the n first uplink carriers. Each group of time slot configuration sets in the multiple groups of time slot configuration sets includes m single time slot pattern indexes, and m is determined according to the following formula: K1 / K min +K2 / K min +…+K n / K min +K n+1 / K min =m; where K1, K2, …, K n , K n+1 are different reference subcarrier spacings SCS of the n + 1 uplink carriers of the terminal device, and K min is the minimum reference subcarrier spacing SCS of the uplink carrier of the terminal device. The n + 1 uplink carriers include n of the first uplink carriers and 1 normal uplink carrier. According to K1 / K min , K2 / K min , …, K n / K min , K n+1 / K min the m single time slot pattern indexes are divided to indicate the time slot configuration of the n + 1 uplink carriers of the terminal device.

[0039] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the single-slot pattern index includes at least one of the following: the single-slot pattern index is the same as the single-slot pattern index configured for the TDD band where the first uplink carrier is located; or the time-domain resources for SUL transmission are indicated according to a predefined first slot pattern; or the time-domain resources for SUL transmission and the flexible time-domain resources are indicated according to a predefined second slot pattern.

[0041] In summary, when the frequency band where the SUL carrier is located multiplexes the TDD band or the low-frequency FDD band, some time-domain resources of the SUL carrier may support some downlink transmissions. Embodiments of the present application configure available time-domain resources for the SUL carrier for uplink transmission, so that SUL transmission is not affected by services such as downlink transmission of the SUL carrier, improving the reliability of transmission and further increasing the capacity of uplink transmission.

[0107] Next, the technical solutions in the present application will be described with reference to the accompanying drawings.

[0108] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD), 5th generation (5G) mobile communication systems, or New Radio (NR) communication systems, as well as future mobile communication systems, etc.

[0109] Figure 1 It is a schematic diagram of the architecture of the mobile communication system applicable to the embodiments of the present application. As Figure 1 shown, the wireless communication system may include at least one network device 101, and the network device 101 communicates with one or more terminal devices (such as Figure 1 the terminal devices 102 and 103 shown in ). When the network device sends a signal, the network device is the transmitting end and the terminal device is the receiving end. Conversely, when the terminal device sends a signal, the terminal device is the transmitting end and the network device is the receiving end.

[0110] The terminal device can be fixed in position or movable. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not drawn in Figure 1 . The embodiments of the present application do not limit the types and quantities of the network devices and terminal devices included in the mobile communication system.

[0111] In the mobile communication system 100, the terminal device accesses the network device in the mobile communication system wirelessly. The network device 101 may be: a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It may also be a gNB in the NR system, or it may also be a component or part of the device that constitutes the base station, such as a central unit (CU), a distributed unit (DU), or a baseband unit (BBU), etc. It should be understood that in the embodiments of the present application, the specific technologies and specific device forms adopted by the network device are not limited. In the present application, if not otherwise specified, in the present application, the network device refers to a radio access network device. In the present application, the network device may refer to the network device itself, or a chip that completes the wireless communication processing function in the network device.

[0112] The terminal device in the mobile communication system 100 may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device in the embodiments of this application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, and may also be a wireless terminal applied to scenarios such as virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, and smart home. In this application, the foregoing terminal device and the chip applicable to the foregoing terminal device are collectively referred to as the terminal device. It should be understood that the embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0113] The embodiments of this application may be applicable to downlink data transmission, may also be applicable to uplink data transmission, and may also be applicable to device-to-device (D2D) data transmission. For downlink data transmission, the data sending device is a network device, and the data receiving device is a terminal device. After receiving the downlink data, the terminal device will send feedback information to the network device to notify the network device whether the downlink data is correctly received by the terminal device. For uplink data transmission, the data sending device is a terminal device, and the data receiving device is a network device. After receiving the uplink data, the network device will send feedback information to the terminal device to notify the terminal device whether the uplink data is correctly received by the network device. For D2D signal transmission, the data sending device is a terminal device, and the data receiving device is also a terminal device. The embodiments of this application do not limit the direction of data transmission.

[0114] It should be understood that the division of the methods, situations, categories, and embodiments in the embodiments of this application is only for convenience of description and should not constitute a special limitation. The features in various methods, categories, situations, and embodiments may be combined without conflict.

[0115] It should also be understood that the "first", "second", and "third" in the embodiments of this application are only for distinction and should not constitute any limitation to this application. For example, the "first uplink carrier" in the embodiments of this application represents the resource used for SUL transmission.

[0116] It should also be understood that in various embodiments of the present application, the magnitudes of the serial numbers of the various processes do not imply the order of execution, and the order of execution of the various processes should be determined by their functions and internal logics, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0117] It should also be noted that in the embodiments of the present application, "predetermined" and "predefined" can be implemented by pre-saving corresponding codes, tables or other means that can be used to indicate relevant information in a device (for example, including a terminal device and a network device). For example, the predefined time slot pattern in the embodiments of the present application can be the time slot configuration method specified in the standard, and the present application does not limit its specific implementation method.

[0118] It should also be noted that "and / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after. The technical solution provided by the present application will be described in detail below with reference to the drawings.

[0119] To facilitate the understanding of the embodiments of the present application, several concepts related to the present application will be briefly introduced below.

[0120] 1. Time slot and time domain symbol

[0121] A time slot can be understood as a part of the serial self-multiplexing of time slot information dedicated to a single channel. A time slot can be understood as a channel.

[0122] In the embodiments of the present application, a symbol, also known as a time domain symbol, can be an orthogonal frequency division multiplexing (OFDM) symbol or a single carrier frequency division multiple access (SC-FDMA) symbol, where SC-FDMA is also known as orthogonal frequency division multiplexing with transform precoding (OFDM with TP), and the embodiments of the present application do not limit this.

[0123] Exemplarily, for the frame structure of the NR frequency division duplex (FDD) mode, the frame length is 10 ms, each frame contains 10 subframes. Taking a 30 KHz subcarrier as an example, each subframe contains 20 time slots. Each subframe has two time slots, each time slot is 0.5 ms and contains 14 OFDM symbols. Each time slot in NR can have several resource blocks, and each resource block contains multiple subcarriers.

[0124] For the frame structure of the NR time division duplex (TDD) mode, the length of one frame is 10 ms, including 10 subframes with a length of 1 ms. Taking a 30 KHz subcarrier as an example, each subframe contains 20 time slots. Each subframe has two time slots, each time slot is 0.5 ms and contains 14 OFDM symbols. Therefore, the entire 10 - ms frame can be understood as being divided into several time slots as the unit for data scheduling and transmission - the transmission time interval (TTI). It should be understood that the embodiments of the present application do not limit the frame structure.

[0125] It should be understood that for different carriers in NR, different carriers can correspond to different reference subcarrier spacings (SCSs), such as 15 KHz, 30 KHz, and 60 KHz, etc. For different reference subcarrier spacings, the number of time slots (slots) included in one subframe is different. For a carrier with an SCS of 15 KHz, each subframe can include 1 time slot; for a carrier with an SCS of 30 KHz, each subframe can include 2 time slots; for a carrier with an SCS of 60 KHz, each subframe can include 4 time slots. Among them, for carriers with different SCSs, each time slot can include 14 symbols (symbols), which will not be elaborated here.

[0126] 2. Physical Uplink Channel

[0127] A channel used to carry uplink control information (UCI) and / or uplink data. For example, this physical uplink channel can include the physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) defined in the LTE protocol or NR protocol, and other uplink channels with the above functions defined as the network evolves.

[0128] 3. Downlink Control Information (DCI)

[0129] It is mainly used to send downlink scheduling assignment information and has multiple different formats, including but not limited to DCI format0-0, 0-1, 1-0, 1-1, 2-0, 2-1, 2-2, 2-3, etc. It should be understood that the embodiments of the present application do not limit the format of DCI.

[0130] 4. Supplementary uplink (SUL)

[0131] In the initial stage of the deployment of 5G mobile communication systems, the frequency bands used are higher than those of the fourth generation (4G) mobile communication systems. Since the characteristics of electromagnetic waves are such that the higher the frequency, the greater the attenuation, and the transmit power of the terminal is lower than that of the base station, terminals at the edge of the cell can receive the downlink signals from the base station, but the base station cannot receive the uplink signals from the terminals, resulting in the uplink coverage range being smaller than the downlink coverage range.

[0132] Figure 2 This is a schematic diagram of cell deployment. According to the background art and the foregoing related introduction, taking the communication process between base station 101 and terminal 102 as an example of network equipment, as Figure 2 shown, an NR cell may include a Normal downlink (NDL) carrier and a Normal uplink (NUL) carrier. Combining Figure 2 with the foregoing related introduction, when currently deploying a cell, the downlink (DL) coverage range of network equipment 101 is greater than the uplink (UL) coverage range, or in other words, the coverage range of the normal downlink (NDL) is greater than the coverage range of the normal uplink (NUL), as Figure 2 shown, the UL coverage range is smaller than the DL coverage range of the first frequency band.

[0133] To improve the uplink coverage of 5G cells, an SUL (supplementary uplink) carrier is introduced in NR. This carrier usually uses a lower frequency and thus has less attenuation, thereby achieving the purpose of improving uplink coverage. Therefore, when actually deploying an NR cell, an NR cell is composed of 3 carriers. For example, a downlink NDL carrier, in the 3.5 Giga Hertz (GHz) frequency band, a NUL carrier, in the 3.5 GHz frequency band, and an SUL carrier, in the 1.8 GHz frequency band. The uplink services of the terminal device can be transmitted on the NUL and SUL.

[0134] To improve the uplink transmission reliability of cell-edge users, the current standard supports the retransmission of PUCCH / PUSCH. The retransmission of PUCCH can be indicated by RRC configuration, and the retransmission of PUSCH can be indicated by downlink control information (DCI) or radio resource control (RRC) signaling configuration. For example, the DCI indication can include DCI dynamic scheduling and Configured Grant Type 2 grant-free scheduling, and the RRC configuration indication can include Configured Grant type 1 grant-free scheduling, etc. Figure 3 is a schematic diagram of transmitting a physical uplink shared channel, as Figure 3 shown, the retransmitted PUCCH / PUSCH can use the same time-domain resources and / or frequency-domain resources on each slot, which will not be elaborated here.

[0135] It should be understood that in the prior art, the SUL band configured for a cell is only used for uplink transmission. Currently, when supporting PUCCH / PUSCH retransmission on the SUL band, it is assumed that the corresponding symbols on the SUL band are uplink symbols, that is, the terminal believes that uplink transmission can be performed on any slot and symbol on the SUL band. However, considering the band deployment and application resource limitations of existing operators, in order to improve resource utilization, some resources of the SUL band can be dynamically or semi-statically configured for other services, and even support some downlink transmissions. When some resources of the SUL band are configured for other services, how to ensure that the original processes such as PUCCH and / or PUSCH retransmission on the SUL band are not affected by other services is an urgent problem to be solved currently.

[0136] The embodiment of the present application provides a method for configuring the SUL band, which can determine the resources for SUL transmission for network devices and terminal devices, and improve the transmission reliability. It should be understood that the embodiment of the present application will take the base station 101 as the network device, and take Figure 2 the transmission process between the base station 101 and the terminal device 102 shown in as an example to specifically introduce the method for configuring the SUL band in the present application.

[0137] Figure 4 is a schematic interaction diagram of a method 400 for determining resources provided by the embodiment of the present application. It should be understood that the embodiment of the present application can be applied to Figure 1 or Figure 2In the shown scenario, specifically, the method 400 can be applied to a terminal device or a base station in this scenario. There are an NDL carrier, an NUL carrier, and one or more SUL carriers configured between the terminal device 102 and the base station 101, which is not limited in the embodiments of the present application.

[0138] As Figure 4 shown, the method 400 includes the following:

[0139] S410, the base station 101 sends first indication information to the terminal device 102, and the first indication information is used to indicate M time-domain resources of a first uplink carrier.

[0140] Optionally, before S410, the first indication information may be determined by the base station 101 from N time-domain resources included in the first uplink carrier, that is, the base station 101 determines M time-domain resources for the terminal device 102 to perform auxiliary uplink SUL transmission, and notifies the terminal device 102 through the first indication information.

[0141] Specifically, the first uplink carrier supports auxiliary uplink SUL transmission, the first uplink carrier includes N time-domain resources, the N time-domain resources include uplink resources and / or flexible time-domain resources, the time-domain resources include time slots and / or symbols, and M < N.

[0142] Optionally, in the embodiments of the present application, the case of M = N may also be included. It should be understood that in the prior art, a dedicated SUL carrier is set, and all uplink resources of the SUL carrier are used for uplink transmission. Through the method provided by the embodiments of the present application, all or part of the time-domain resources of the SUL carrier can be configured to send uplink signals / uplink channels. Or, within a period of time, all the time-domain resources of the SUL carrier are configured for uplink transmission. Compared with the case where all the time-domain resources of the SUL carrier are used for uplink transmission at any time, the configuration method is more flexible and the resource utilization rate is higher.

[0143] S420, the terminal device 102 determines the M time-domain resources for performing auxiliary uplink SUL transmission from the N time-domain resources included in the first uplink carrier according to the first indication information.

[0144] The base station 101 sends the first indication information to the terminal device 102 according to various methods described in S420, and the terminal device 102 can configure M available time-domain resources for the SUL carrier according to the first indication information.

[0145] S430, the terminal device 102 sends a first uplink signal and / or an uplink channel to the base station 101 through the M time-domain resources of the first uplink carrier. Correspondingly, the base station 101 receives the first uplink signal and / or the uplink channel sent by the terminal device 102 through the M time-domain resources of the first uplink carrier.

[0146] It should be understood that in the embodiments of the present application, the first uplink carrier may also be referred to as the "SUL carrier", and one or more first uplink carriers may be included in the system, that is, one or more SUL carriers are included. In the embodiments of the present application, the method for configuring the available resources of the SUL carrier will be described by taking one SUL carrier as an example, and the number of SUL carriers (the first uplink carriers) in the embodiments of the present application is not limited.

[0147] It should also be understood that the frequency band where the first uplink carrier is located in the embodiments of the present application is a TDD frequency band, and the frequency band where the first uplink carrier is located also includes other resources for downlink transmission. In other words, one or more SUL carriers in the embodiments of the present application multiplex the existing TDD frequency band of LTE or the low-frequency FDD frequency band of NR deployment, and the one or more SUL carriers are different from the dedicated SUL carriers configured in the prior art. Specifically, any resources in the dedicated SUL carriers configured in the prior art can be used for uplink transmission, that is, for sending PUCCH / PUSCH.

[0148] In a possible scenario, the base station 101 may provide carriers for multiple terminal devices. For example, the base station 101 may provide an NR carrier for the first terminal device for uplink and downlink transmissions (NUL and NDL) of the terminal device; in addition, the base station 101 may also provide an LTE carrier for the second terminal device for uplink and downlink transmissions (NUL and NDL) of the second terminal device. Optionally, the frequency point of the frequency band where the NR carrier of the first terminal device is located may be higher than the frequency point of the frequency band where the LTE carrier of the second terminal device is located. In this scenario, in combination with the embodiments of the present application, the SUL carrier of the first terminal device may multiplex the LTE carrier in the lower frequency band of the second terminal device.

[0149] Alternatively, in another possible scenario, both the first terminal device and the second terminal device may be terminal devices operating in NR, and the base station 101 provides NR carriers for the first terminal device and the second terminal device respectively. Optionally, the frequency band range of the frequency band where the NR carrier of the first terminal device is located may be different from the frequency band range of the frequency band where the NR carrier of the second terminal device is located. In this scenario, in combination with the embodiments of the present application, the SUL carrier of the first terminal device may multiplex the NR carrier in the lower frequency band of the second terminal device, or the SUL carrier of the second terminal device may multiplex the NR carrier in the lower frequency band of the first terminal device. It should be understood that the embodiments of the present application do not limit the available scenarios.

[0150] Optionally, the frequency band where the SUL carrier is located can reuse the TDD frequency band of LTE or the low-frequency FDD frequency band of NR deployment. Specifically, the base station 101 can configure available SUL carriers for the terminal device 102, or pre-define associated SUL carriers for the NDL / NUL frequency bands of the terminal device 102 in various possible ways. This method is introduced in detail in other related patent applications, and will not be elaborated in this embodiment of the present application.

[0151] It should also be understood that in this embodiment of the present application, the first uplink carrier supporting secondary uplink (SUL) transmission may include N time-domain resources, and the time-domain resources may specifically refer to the "time slot" and / or "time-domain symbol" introduced above.

[0152] Optionally, among the N time-domain resources of the first uplink carrier, there may be included one or more of the time-domain resources configured for uplink transmission (labeled as "U"), flexible time-domain resources (labeled as "F"), and unavailable time-domain resources (labeled as "D").

[0153] The method provided in this embodiment of the present application can configure the time slots and / or symbols for sending uplink signals and / or uplink channels on one or more SUL carriers, or configure the number of time slots or symbols for sending the first uplink signal and / or uplink channel on the SUL carrier. This embodiment of the present application does not make any limitations in this regard.

[0154] Assuming that symbols are used as the unit of time-domain resources, for a SUL carrier, assuming that the SUL carrier includes N symbols, the base station 101 can determine M symbols from the N symbols for the terminal device 102 to send the first uplink signal and / or uplink channel. In this process, the base station 101 can determine the positions of the M symbols and / or the number of symbols M, and notify the terminal device 102 of the positions of the M symbols and / or the number of symbols M.

[0155] In a possible implementation, the base station 101 can only tell the terminal device 102 the information of the M time-domain resources through the first indication information, such as the positions, quantities, etc. of the M time-domain resources. The terminal device 102 can determine the time-domain resources for sending the first uplink signal and / or uplink channel based on the position and quantity information of the M time-domain resources indicated by the first indication information.

[0156] Optionally, the M time-domain resources are the time-domain resources configured as "U", that is, the first indication information is used to configure the uplink resources of the SUL carrier.

[0157] In another possible implementation, when the N time-domain resources include flexible time-domain resources, the first indication information is further used to indicate K flexible time-domain resources, where the flexible time-domain resources are used for SUL transmission or downlink transmission, and K < N; and the process of S430 may specifically be: The terminal device 102 sends a first uplink signal and / or an uplink channel to the base station 101 through the M time-domain resources and the K flexible time-domain resources of the first uplink carrier. Correspondingly, the base station 101 receives the first uplink signal and / or the uplink channel through the M time-domain resources and the K flexible time-domain resources of the first uplink carrier.

[0158] It should be understood that the flexible time-domain resources can be further configured for uplink transmission or downlink transmission. In other words, the resources marked as "F" can be further configured as "U" or "D". When the N time-domain resources include flexible time-domain resources, in addition to telling the terminal device 102 the information of the time-domain resources that can be used for uplink transmission (marked as "U"), the base station 101 can also tell the terminal device 102 the information of the flexible (marked as "F") time-domain resources. Among them, the time-domain resources configured as U and F can be used for SUL transmission.

[0159] In another possible implementation, the time slots and / or symbols used by the first uplink carrier are configured as a subset of the uplink time slots and / or symbols and flexible time slots and / or symbols to which the frequency band where the first uplink carrier is located belongs; or the time slots and / or symbols used by the first uplink carrier are configured as a subset of the uplink time slots and / or symbols or flexible time slots and / or symbols to which the frequency band where the first uplink carrier is located belongs.

[0160] Exemplarily, the base station 101 tells the terminal device 102 through the first indication information that it can determine the configuration of the time-domain resources of the SUL carrier according to a subset of the configuration set of the uplink time slots and / or flexible time slots of the frequency band where the SUL carrier is located.

[0161] It should be understood that the "subset" here may include configuring the time slots of the SUL carrier according to the same number of uplink time slots and / or flexible time slots, or configuring the symbols of the SUL carrier according to the same number of uplink symbols and / or flexible symbols. Or, configuring the time slots of the SUL carrier according to a number of uplink time slots and / or flexible time slots less than that included in the frequency band where the SUL carrier is located, or configuring the symbols of the SUL carrier according to a number of uplink symbols and / or flexible symbols less than that included in the frequency band where the SUL carrier is located. The embodiments of the present application do not make any limitations in this regard.

[0162] Optionally, the base station 101 may send the first indication information to the terminal device 102 in different ways, that is, the first indication information may be carried in different messages. Exemplarily, the first indication information may be carried in a system information block (SIB); or the first indication information is carried in downlink control information DCI; or the first indication information is carried in radio resource control (RRC) dedicated signaling.

[0163] Three possible implementation manners of the first indication information in S410 will be specifically introduced below.

[0164] Manner 1

[0165] In a possible implementation manner, the base station 101 may send the first indication information to the terminal device 102 through the system information block SIB, and configure M time domain resources for one or more first uplink carriers through the first indication information.

[0166] Optionally, when the N time domain resources include flexible time domain resources, the SIB is further used to indicate K of the flexible time domain resources, so that the terminal device 102 may send a first uplink signal and / or an uplink channel to the base station 101 through the M time domain resources and the K flexible time domain resources of the first uplink carrier. Correspondingly, the base station 101 receives the first uplink signal and / or the uplink channel through the M time domain resources and the K flexible time domain resources of the first uplink carrier.

[0167] Optionally, the SIB may include multiple configuration parameters, and the configuration parameters may include the reference sub-carrier spacing (SCS) of the first uplink carrier and at least one configuration pattern. Further, the configuration pattern may include a configuration period in the configuration pattern. The terminal device 102 may obtain information about M time domain resources, that is, available uplink resources, according to at least one configuration pattern and the configuration period in the configuration pattern.

[0168] Optionally, at least one configuration pattern may include a single configuration pattern, a dual configuration pattern, etc. Among them, the period and the configuration format of the time domain resources in each pattern of the single configuration pattern are the same, and the period and the configuration format of the time domain resources in each pattern of the dual configuration pattern may be different.

[0169] Figure 5 is a schematic diagram of time domain resource configuration of a single configuration pattern provided in an embodiment of the present application. Exemplarily, such as Figure 5As shown, U is used to represent time slots and / or symbols configured as uplink resources, F is used to represent time slots and / or symbols configured as flexible time-domain resources, and D is used to represent time slots and / or symbols configured as unavailable time-domain resources. Optionally, the unavailable time-domain resources may be time-domain resources configured for downlink transmission, and the embodiments of the present application do not limit this.

[0170] For the time-domain resources in the single-configuration mode, during the process that the base station 101 indicates the configuration parameters of the first uplink carrier through the first indication information within one period, the first indication information may include the configuration parameters of at least one of the following situations:

[0171] (1) Configuring the time slots and / or symbols of the uplink resources. Exemplarily, taking the number of time slots and / or symbols as an example, configure Figure 5 the number of time slots x1 and / or the number of symbols x2 of the uplink resources marked as U in

[0172] (2) Configuring the symbols of the uplink resources. Exemplarily, taking the number of symbols as an example, configure Figure 5 the number of symbols X of the uplink resources marked as U in

[0173] (3) Configuring the time slots and / or symbols of the uplink resources and the flexible time-domain resources. Exemplarily, taking the number of time slots and / or symbols as an example, configure Figure 5 the number of time slots x1 and / or the number of symbols x2 of the uplink resources marked as U in

[0174] (4) Configuring the symbols of the uplink resources and the flexible time-domain resources. Exemplarily, taking the number of symbols as an example, configure Figure 5 the number of symbols X of the uplink resources marked as U and the number of symbols Y of the flexible time-domain resources marked as F in

[0175] (5) Configuring the time slots and / or symbols of the uplink resources and the unavailable time-domain resources. Exemplarily, taking the number of time slots and / or symbols as an example, configure Figure 5 the number of time slots x1 and / or the number of symbols x2 of the uplink resources marked as U in

[0176] (6) Configuring the symbols of the uplink resources and the unavailable time-domain resources. Exemplarily, taking the number of symbols as an example, configure Figure 5 the number of symbols X of the uplink resources marked as U and the number of symbols Z of the unavailable time-domain resources marked as D in

[0177] (7) Configure the time slots and / or symbols of the uplink resources, flexible time-domain resources, and unavailable time-domain resources. Exemplarily, taking the number of time slots and / or symbols as an example, configure Figure 5 the number of time slots x1 and / or the number of symbols x2 of the uplink resources marked as U in Figure 5 , the number of time slots y1 and / or the number of symbols y2 + y3 of the flexible time-domain resources marked as F, and the number of time slots z1 and / or the number of symbols z2 of the unavailable time-domain resources marked as D;

[0178] (8) Configure the symbols of the uplink resources, flexible time-domain resources, and unavailable time-domain resources. Exemplarily, taking the number of symbols as an example, configure Figure 5 the number of symbols X of the uplink resources marked as U, the number of symbols Y of the flexible time-domain resources marked as F, and the number of symbols Z of the unavailable time-domain resources marked as D in Figure 5 .

[0179] It should be understood that the base station 101 can select any possible way to configure the first uplink carrier for the terminal device 102, so that the terminal device 102 can determine the time slots and / or symbols of the M time-domain resources for SUL transmission according to the first indication information.

[0180] It should also be understood that among the above-mentioned various possible ways, the less configuration information included in the first indication information, the more signaling overhead can be saved. For example, configuration method (1) includes fewer configuration parameter information than configuration method (8), thus saving signaling overhead.

[0181] In a possible implementation manner, after the base station 101 tells the terminal device 102 the M time-domain resources and K flexible time-domain resources for SUL transmission through the first indication information, the terminal device 102 can, in a pattern, configure the time-domain resources of "U" and the time-domain resources of "F" in the reverse configuration order and sequentially, and determine the time-domain resources of "F" and "U" as the time-domain resources that can perform SUL transmission, and determine the remaining time-domain resources in the pattern as unavailable time-domain resources.

[0182] Exemplarily, taking the above-listed configuration case (8) as an example, as Figure 5As shown, in a pattern, the terminal device 102 first configures X symbols as uplink resources from the back to the front, marks these X symbols as "U", then continues to configure Y symbols as flexible time-domain resources, marks these Y symbols as "F", then continues to configure Z symbols as unavailable time-domain resources, marks these Z symbols as "D", and determines the time-domain resources of "F" and the time-domain resources of "U" as the time-domain resources that can perform SUL transmission. Similarly, in the process of configuring time-domain resources introduced later, it can also be configured according to this implementation method, or configured in the order from the front to the back in each pattern. The embodiments of the present application do not limit this.

[0183] It should be understood that for dual-configuration modes, etc., each pattern can be configured according to the single-configuration mode introduced above, which will not be elaborated here.

[0184] In a possible implementation, for multiple SUL carriers, common configuration parameters can be included in the SIB. In other words, only the parameters different from the common configuration parameters are configured for multiple SUL carriers to reduce signaling overhead.

[0185] Figure 6 It is a schematic diagram of time-domain resource configuration for a dual-configuration mode provided by an embodiment of the present application. Exemplarily, as Figure 6 shown, it includes the configuration parameters in two patterns, and the configuration parameters in the two patterns are different. For example, some or all of the number of symbols included in X, Y, and Z in configuration mode one are different.

[0186] In this implementation, the first indication information can indicate the configuration parameters of the time-domain resources within one period of configuration mode one and can also indicate the configuration parameters of the time-domain resources within one period of configuration mode two. For the time-domain resources of the dual-configuration mode, the time-domain resources of configuration mode one and configuration mode two cycle in sequence to complete the time-domain resource configuration of the first uplink carrier, which will not be elaborated here.

[0187] According to the method provided in Method 1, the base station 101 can semi-statically configure available time-domain resources for one or more SUL carriers through the SIB. After receiving the SIB, the terminal device 102 determines the time-domain resources configured as U and / or F as the time-domain resources that can perform uplink transmission according to the configuration information (the first indication information) in the SIB, and determines other time-domain resources as unavailable time-domain resources.

[0188] Through the above solution, embodiments of the present application can configure time-domain resources available for one or more SUL carriers. When the frequency band where the SUL carrier is located multiplexes a TDD frequency band or a low-frequency FDD frequency band, some time-domain resources of the SUL carrier may support some downlink transmissions. Embodiments of the present application configure time-domain resources available for uplink transmission for the SUL carrier, so that SUL transmission is not affected by services such as downlink transmission of the SUL carrier, improving the reliability of transmission and further improving the capacity of uplink transmission. In addition, part of the time-domain resources of the one or more SUL carriers can be configured as dynamic or semi-static for other services to use, which can improve the resource utilization efficiency.

[0189] In another possible implementation, when the base station 101 sends the first indication information to the terminal device 102 through the SIB introduced in the first method, and the N time-domain resources of the first uplink carrier configured through the SIB include K flexible time-domain resources, after S410-S420, the following steps may further be included:

[0190] S440, the base station 101 sends the second indication information to the terminal device 102, and the second indication information is used to indicate L time-domain resources for SUL transmission among the K flexible time-domain resources, where the L time-domain resources include L0 uplink resources and L1 flexible time-domain resources, 0≤L≤K;

[0191] S420-1, the terminal device 102 determines L time-domain resources for SUL transmission from the K flexible time-domain resources according to the second indication information.

[0192] It should be understood that the L time-domain resources here may include L0 uplink resources and L1 flexible time-domain resources. In other words, the L time-domain resources here may include L0 resources configured as "U" and L1 flexible time-domain resources configured as "F".

[0193] S430-1, the terminal device 102 sends the first uplink signal and / or uplink channel to the base station 101 through the M time-domain resources and the L time-domain resources. Correspondingly, the base station 101 receives the first uplink signal and / or uplink channel sent by the terminal device 102 through the M time-domain resources and the L time-domain resources of the first uplink carrier.

[0194] It should be understood that after the base station 101 configures M+K time-domain resources of one or more SUL carriers for the terminal device 102 through S410-S420, the time-domain resources of the one or more SUL carriers that have been configured can also be modified according to different scenarios and requirements, that is, the configuration of the flexible time-domain resources is modified through the second indication information provided by the embodiments of the present application.

[0195] It should also be understood that when the configuration of the flexible time-domain resource is modified by the second indication information, S420-1 and S430-1 can be understood as a specific implementation form of S420 and S430, that is, S420-1 and S430-1 can replace S420 and S430, and the purpose is to determine the time-domain resource for transmitting the first uplink signal / channel. The embodiments of the present application do not limit this.

[0196] It should also be understood that S440, S420-1 and S430-1 are optional steps in the embodiments of the present application, and are thus shown in the dashed box in Figure 4 method 400.

[0197] It should be understood that the configuration period of the SUL carrier can be the same as the period of the SIB semi-static configuration introduced in Method 1. When further configuring the time-domain resource of the SUL carrier through the first RRC dedicated signaling, the configuration parameters of the first RRC dedicated signaling can overwrite the flexible time-domain resource (F) part configured by the SIB in the original Method 1, and after accepting the configuration of the first RRC dedicated signaling, each period of the SUL carrier changes according to the configuration parameters of the first RRC dedicated signaling. Optionally, when the first indication information is sent through the SIB, the second indication information can be implemented in the following two ways:

[0198] 1. Implementation Method 1

[0199] Optionally, when the first indication information is sent through the SIB, the second indication information can be carried in the first Radio Resource Control (RRC) dedicated signaling.

[0200] Specifically, the first RRC dedicated signaling can also be implemented in any of the following possible ways to further modify the configuration of the flexible time-domain resource of the SUL carrier. For example:

[0201] (1) Allocate some time slots of the SUL carrier as time-domain resources for uplink transmission, that is, mark these time slots as U;

[0202] (2) Allocate all the symbols included in a time slot of the SUL carrier as time-domain resources for uplink transmission, that is, mark all the symbols of this time slot as U;

[0203] (3) Configure the number of flexible symbols (nrofFlexibleSymbols) and / or the number of uplink transmission symbols (nrofUplinkSymbols) of a time slot.

[0204] Specifically, the first RRC dedicated signaling can be embodied in the following form:

[0205] TDD-SUL-Config Dedicated::=SEQUENCE{

[0206] slotSpecificConfigurationsToAddModlist

[0207] SEQUENCE(size(1…maxNrofslots)) OF SUL-slotConfig

[0208] slotSpecificConfigurationsToReleaselist

[0209] SEQUENCE(size(1…maxNrofslots)) OF SUL-slotConfig

[0210] }

[0211] SUL-slotConfig ::= SEQUENCE {

[0212] slotIndex SUL-slotIndex

[0213] symbols CHOICE {

[0214] allUplink NULL,

[0215] explicit SEQUENCE {

[0216] nrofFlexibleSymbols INTEDER(1…maxNrofUplinkSymbols - 1)

[0217] nrofUplinkSymbols INTEDER(1…maxNrofUplinkSymbols - 1)}

[0218] }

[0219] }

[0220] It should be understood that the above implementation method sends the second indication information to the terminal device 102 through the first RRC dedicated signaling, and further modifies the flexible time-domain resource F configured in the original SIB. Exemplarily, the first indication information configures K flexible time-domain resources, and the second indication information can reconfigure L time-domain resources among the K flexible time-domain resources as uplink resources for SUL transmission, where the L time-domain resources include L0 uplink resources and L1 flexible time-domain resources, and 0 ≤ L ≤ K.

[0221] Further, for Implementation Manner 1, the base station 101 first sends first indication information to the terminal device 102 through the SIB, configuring the time-domain resources of one or more SUL carriers; then sends second indication information to the terminal device 102 through the first RRC dedicated signaling. After modifying the flexible time-domain resources of one or more SUL carriers, the flexible time-domain resources of the one or more already configured SUL carriers can be further modified, that is, modified through the third indication information provided in the embodiments of the present application. In other words, when the base station 101 sends the first indication information to the terminal device 102 through the SIB introduced in Implementation Manner 1, and configures the M time-domain resources and L time-domain resources of the first uplink carrier to be available for SUL transmission through the second indication information of the first RRC dedicated signaling, after S410, S420, S440, and S420-1, the embodiments of the present application may further include the following steps:

[0222] S450, the base station 101 sends third indication information to the terminal device 102, where the third indication information is used to indicate S time-domain resources for uplink transmission among the L1 flexible time-domain resources, 0≤S≤L1.

[0223] S420-2, the terminal device 102 determines S time-domain resources for SUL transmission from the L1 flexible time-domain resources according to the third indication information.

[0224] It should be understood that the S time-domain resources here may include S0 uplink resources and S1 flexible time-domain resources. In other words, the S time-domain resources here may include S0 resources configured as "U" and S1 flexible time-domain resources configured as "F".

[0225] It should also be understood that the base station 101 can also modify the L1 flexible time-domain resources of one or more already configured SUL carriers according to different scenarios and requirements, that is, modify the configuration of the flexible time-domain resources through the third indication information provided in the embodiments of the present application.

[0226] S430-2, the terminal device 102 sends a first uplink signal and / or an uplink channel to the base station 101 through the M time-domain resources, L0 uplink resources, and S time-domain resources. Correspondingly, the base station 101 receives the first uplink signal and / or the uplink channel sent by the terminal device 102 through the M time-domain resources, L0 uplink resources, and S time-domain resources of the first uplink carrier.

[0227] It should be understood that when the configuration of the flexible time-domain resource is further modified by the third indication information, S420-2 and S430-2 can be understood as a specific implementation form of S420 and S430. Or rather, the implementation processes of S420-2 and S430-2, S420-1 and S430-1 can replace those of S420 and S430, aiming to determine the time-domain resource for transmitting the first uplink signal / channel. The embodiments of the present application do not limit this.

[0228] It should also be understood that S450, S420-2 and S430-2 are optional steps in the embodiments of the present application, and thus are shown in the dashed box in Figure 4 Method 400.

[0229] Optionally, the third indication information may be carried in the downlink control information DCI or the media access control element (MAC CE), and the DCI is used to indicate one or more of the first uplink carriers for SUL transmission.

[0230] Optionally, the DCI or the MAC CE may further configure the specified time slots and / or symbols on the SUL carrier as the time-domain resources for transmitting the first uplink signal / channel. Exemplarily, the DCI or the MAC CE may include the third indication information for re-indicating the configuration of the flexible time-domain resources of the SUL carrier within a certain period.

[0231] Exemplarily, when the third indication information is carried by the DCI or the MAC CE to configure the time-domain resources within a certain duration (e.g., 10 ms), starting from the moment when the terminal device 102 receives the third indication information, the SUL carrier is reconfigured according to the time-domain resource configuration rules indicated by the third indication information within 10 ms after receiving the third indication information, until a new DCI or MAC CE is received.

[0232] Outside 10 ms, for example, within the period from 11 ms to 15 ms, the time-domain resources of the SUL carrier are configured according to the configuration rules of the original first indication information and / or the second indication information; or, if the time-domain resources of the SUL carrier are not configured by the previous first indication information and / or the second indication information, the time-domain resources of the SUL carrier may be all configured as uplink resources. The configuration rules of the DCI will not be elaborated in the subsequent embodiments.

[0233] In addition, if there are one or more SUL carriers and the one or more SUL carriers and the NUL in the same cell include at least two different subcarrier spacings, when the DCI or the MAC CE indicates multiple groups of time slot configuration sets for configuring n SUL carriers, the n SUL carriers can be configured in different ways.

[0234] In a possible configuration, it is assumed that the n + 1 uplink carriers of the terminal device include n SUL carriers and 1 NUL carrier. The reference subcarrier spacings (SCS) of the n + 1 uplink carriers are respectively denoted as K1, K2, …, K n , K n+1 , where K min is the minimum reference subcarrier spacing among the uplink carriers of the terminal device. The ratios between the reference subcarrier spacings of each uplink carrier and the minimum reference subcarrier spacing are denoted as K1 / K min , K2 / K min , …, K n / K min , K n+1 / K min .

[0235] DCI or MAC CE can indicate multiple sets of slot configuration sets (SlotFormatCombination). Among them, the multiple sets of slot configuration sets can be predefined by RRC, and each set of slot configuration sets in the multiple sets of slot configuration sets can contain m preconfigured single-slot pattern indexes, and m can be determined according to the following formula:

[0236] K1 / K min + K2 / K min + … + K n / K min + K n+1 / K min = m Formula (1)

[0237] In other words, each set of slot configuration sets indicated by DCI or MAC CE contains m preconfigured single-slot pattern indexes to configure time-domain resources for the n + 1 uplink carriers of the terminal device.

[0238] Figure 7 is another schematic diagram of time-domain resource configuration provided by the embodiments of the present application. Exemplarily, as Figure 7 shown, taking 1 NUL carrier and 2 SUL carriers of the terminal device as an example, the reference subcarrier spacing corresponding to 1 NUL carrier is 60 KHz, and the reference subcarrier spacings corresponding to the 2 SUL carriers are 30 KHz and 15 KHz respectively. Taking the time slot of the SUL carrier with the minimum reference subcarrier spacing as the unit period, within this unit period, there can be 4 time slot configurations corresponding to the NUL carrier and 2 time slot configurations corresponding to SUL 1. Specifically, m can be calculated according to the above Formula (1).

[0239] m = K1 / K min + K2 / K min + … + K n / K min + Kn+1 / K min = 30 / 15 + 60 / 15 + 15 / 15 = 2 + 4 + 1 = 7

[0240] Therefore, each set of time slot configuration sets indicated by DCI or MAC CE contains 7 pre-configured single time slot pattern indexes, and time domain resources are configured for 3 uplink carriers of the terminal device within a unit period.

[0241] Optionally, in a possible implementation, the single time slot pattern index may reuse the single time slot pattern configured for the TDD band where the SUL carrier is located, and the terminal device may ignore the configuration of the downlink symbol (D) in the single time slot pattern.

[0242] Alternatively, the single time slot pattern index is determined according to a preset rule. According to a predefined first time slot pattern, the time domain resources for SUL transmission are indicated. Or, according to a predefined second time slot pattern, the time domain resources for SUL transmission and the flexible time domain resources are indicated.

[0243] Exemplarily, Figure 8 is another schematic diagram of time domain resource configuration provided by an embodiment of the present application. Exemplarily, as shown in Figure 8 figure (a) therein, the single time slot pattern index reuses the time slot configuration table in the existing standard, or, as shown in Figure 8 figure (b) therein, the single time slot pattern index is a newly defined time slot configuration table in the standard, and the embodiments of the present application do not limit this.

[0244] It should be understood that whether reusing the time slot configuration table in the existing standard or newly defining the time slot configuration table in the standard, each set of time slot configuration sets contains 7 pre-configured single time slot pattern indexes. For example, the time slot configuration set {10, 11, 1, 1, 1, 2, 10} represents Figure 7 in which time slots 1, 2, 3, and 4 of 60KHz NUL are configured with 10, 11, 1, and 1, that is, time slot 1 is configured with 14 symbols according to the table row number 10 defined in Figure 8 figure (a) therein. Similarly, time slots 3 and 4 are configured with 14 symbols according to the table row number 1 defined in Figure 8 figure (b) therein, which will not be elaborated here.

[0245] 2. Implementation Method 2

[0246] Optionally, when the first indication information is sent through SIB, the second indication information may also be carried in downlink control information DCI or MAC CE.

[0247] Specifically, in the above implementation manner, the second indication information is sent to the terminal device 102 through DCI or MAC CE to further modify the flexible time-domain resource F configured in the original SIB. Exemplarily, the first indication information configures K flexible time-domain resources, and the second indication information can reconfigure L time-domain resources among the K flexible time-domain resources as uplink resources for SUL transmission, where 0 ≤ L ≤ K.

[0248] In the second implementation manner, there may be no process in which the base station 101 further modifies the time-domain resources of the SUL carrier through the third indication information. In other words, there is no process of S450, S420-2, and S430-2 introduced above.

[0249] When further configuring the time-domain resources of the SUL carrier through DCI or MAC CE, the configuration parameters of the DCI or MAC CE can cover the flexible time-domain resource (F) part configured in the original manner one. Specifically, the process of modifying the time-domain resources of the SUL carrier through DCI or MAC CE can refer to the foregoing introduction and Figure 7 、 Figure 8 the process, which will not be elaborated here.

[0250] Manner Two

[0251] In another possible implementation manner, the base station 101 can send the first indication information to the terminal device 102 through the second RRC dedicated signaling, and configure M time-domain resources for one or more first uplink carriers through the first indication information.

[0252] Optionally, when the N time-domain resources include flexible time-domain resources, the second RRC dedicated signaling is further used to indicate K of the flexible time-domain resources. Then, the terminal device 102 can send the first uplink signal and / or uplink channel to the base station 101 through the M time-domain resources of the first uplink carrier and the K flexible time-domain resources. Correspondingly, the base station 101 receives the first uplink signal and / or uplink channel through the M time-domain resources of the first uplink carrier and the K flexible time-domain resources. Optionally, the specified time slots and / or symbols on the SUL carrier can be configured in the second RRC dedicated signaling as the time-domain resources for sending the first uplink signal / channel. Exemplarily, the first indication information included in the second RRC dedicated signaling can configure the SUL carrier in any one of the 8 configuration manners introduced in Manner One, which will not be elaborated here. Please refer to the specific introduction in Manner One.

[0253] Specifically, the base station 101 can also configure the time-domain resources of the SUL carrier for the terminal device 102 through the second RRC dedicated signaling and select 8 possible ways introduced in the above method 1, so that the terminal device 102 can determine the time slots and / or symbols of M time-domain resources or M+K time-domain resources for SUL transmission according to the second RRC dedicated signaling, achieving the same configuration effect as the SIB in method 1.

[0254] It should also be understood that the second RRC dedicated signaling here is different from the first RRC dedicated signaling in method 1. The first RRC dedicated signaling is a possible implementation manner of the second indication information. Therefore, the first RRC dedicated signaling and the second RRC dedicated signaling are only used to distinguish RRC dedicated signaling for different purposes in different scenarios. In the specific implementation process, the format, content, etc. of the RRC dedicated signaling are not limited.

[0255] In a possible implementation manner, for multiple SUL carriers, common configuration parameters can be included in the second RRC dedicated signaling. In other words, only parameters different from the common configuration parameters are configured for multiple SUL carriers to reduce signaling overhead.

[0256] In another possible implementation manner, when the base station 101 sends the first indication information to the terminal device 102 through the second RRC dedicated signaling introduced in method 2 and configures K flexible time-domain resources among the N time-domain resources of the first uplink carrier through the second RRC dedicated signaling, after S410 - S420, it can also include Figure 4 the processes of S440, S420-1, and S430-1 in, which will not be elaborated here.

[0257] It should be understood that after the base station 101 configures the time-domain resources of one or more SUL carriers for the terminal device 102 through S410 - S420, it can also modify the flexible time-domain resources of the one or more already configured SUL carriers according to different scenarios and requirements, that is, modify the flexible time-domain resources through the second indication information provided in the embodiments of the present application. And when the first indication information is sent through the second RRC dedicated signaling, the second indication information can have the following 2 implementation manners:

[0258] 1. Implementation manner 1

[0259] Optionally, when the first indication information is sent through the second RRC dedicated signaling, the second indication information can be carried in the first radio resource control RRC dedicated signaling. The specific process of further modifying the original configuration of the SUL carrier through the first RRC dedicated signaling can refer to the relevant description in implementation manner 1 of method 1, which will not be elaborated here.

[0260] Specifically, the above implementation sends the second indication information to the terminal device 102 through the first RRC dedicated signaling, and further modifies the flexible time-domain resource F configured in the original second RRC dedicated signaling. Exemplarily, the first indication information configures K flexible time-domain resources, and the second indication information can reconfigure L of the K flexible time-domain resources into uplink resources for SUL transmission, where the L time-domain resources include L0 uplink resources and L1 flexible time-domain resources, and 0 ≤ L ≤ K.

[0261] Further, for the first implementation method, the base station 101 first sends the first indication information to the terminal device 102 through the second RRC dedicated signaling, and then sends the second indication information to the terminal device 102 through the first RRC dedicated signaling. After configuring the time-domain resources of one or more SUL carriers, the flexible time-domain resources of the one or more SUL carriers that have been configured can be further modified, that is, the foregoing L1 flexible time-domain resources are modified through the third indication information provided by the embodiments of the present application. In other words, after S440, S420-1, and S430-1, it may further include Figure 4 the processes of S450, S420-2, and S430-2 in, which will not be elaborated here.

[0262] Optionally, the third indication information may be carried in DCI or MAC CE, and the DCI is used to indicate one or more of the first uplink carriers for SUL transmission. The specific process of further modifying the original configuration of the SUL carrier through the third indication information included in DCI or MAC CE may refer to the relevant description in the first implementation method of the first method, which will not be elaborated here.

[0263] 2. Second implementation method

[0264] Optionally, when the first indication information is sent through the second RRC dedicated signaling, the second indication information may also be carried in DCI or MAC CE.

[0265] Specifically, the above implementation sends the second indication information to the terminal device 102 through DCI or MAC CE, and further modifies the flexible time-domain resource F configured in the original second RRC dedicated signaling. Exemplarily, the first indication information configures K flexible time-domain resources, and the second indication information can reconfigure L of the K flexible time-domain resources into L0 uplink resources and L1 flexible time-domain resources for SUL transmission, where 0 ≤ L ≤ K.

[0266] In the second implementation method, there may be no process in which the base station 101 further modifies the time-domain resources of the SUL carrier through the third indication information. In other words, there is no process of S450, S420-2, and S430-2 described above, which will not be elaborated here.

[0267] Through the above solution, embodiments of the present application can configure time-domain resources available for one or more SUL carriers. When the frequency band where the SUL carrier is located multiplexes the TDD frequency band or the low-frequency FDD frequency band, some time-domain resources of the SUL carrier may support some downlink transmissions. Embodiments of the present application configure time-domain resources available for uplink transmission for the SUL carrier, so that SUL transmission is not affected by services such as downlink transmission of the SUL carrier, improving the reliability of transmission and further increasing the capacity of uplink transmission. In addition, some time-domain resources of the one or more SUL carriers can be configured as dynamic or semi-static for other services to use, which can improve the resource utilization efficiency.

[0268] Method 3

[0269] In another possible implementation, the base station 101 can dynamically send the first indication information to the terminal device 102 through DCI or MAC CE, and configure M time-domain resources for one or more first uplink carriers through the first indication information.

[0270] Optionally, when the N time-domain resources include flexible time-domain resources, DCI or MAC CE is further used to indicate K of the flexible time-domain resources. Then, the terminal device 102 can send a first uplink signal and / or an uplink channel to the base station 101 through the M time-domain resources of the first uplink carrier and the K flexible time-domain resources. Correspondingly, the base station 101 receives the first uplink signal and / or the uplink channel through the M time-domain resources of the first uplink carrier and the K flexible time-domain resources. Specifically, the above implementation sends the first indication information to the terminal device 102 through DCI or MAC CE to configure the time-domain resources of the SUL carrier. The specific process of further modifying the original configuration of the SUL carrier through the first indication information included in DCI or MAC CE can refer to the relevant description in the first implementation manner of Method 1, which will not be elaborated here.

[0271] It should be understood that in this Method 3, there may be no process in which the base station 101 modifies the L1 flexible time-domain resources of the SUL carrier again through the second indication information and the third indication information. In other words, there are no processes of S440, S420-1 and S430-1, and S450, S420-2 and S430-2 introduced above.

[0272] According to the method provided in Mode 3, the base station 101 can dynamically configure available time-domain resources for one or more SUL carriers through DCI or MAC CE. After receiving the DCI or MAC CE, the terminal device 102 determines the time-domain resources configured as U and / or F as the time-domain resources available for uplink transmission according to the configuration information (the first indication information) in the DCI or MAC CE, and determines other time-domain resources as unavailable time-domain resources.

[0273] Through the above solution, embodiments of the present application can configure available time-domain resources for one or more SUL carriers. When the frequency band where the SUL carrier is located multiplexes the TDD frequency band or the low-frequency FDD frequency band, some time-domain resources of the SUL carrier may support some downlink transmissions. Embodiments of the present application configure available uplink transmission time-domain resources for the SUL carrier, so that SUL transmission is not affected by services such as downlink transmission of the SUL carrier, improving the reliability of transmission and further improving the uplink transmission capacity. In addition, some time-domain resources of the one or more SUL carriers can be configured as dynamic or semi-static for other services, which can improve the resource utilization efficiency.

[0274] It should be noted here that in the process of configuring the time-domain resources of the SUL carrier for the terminal device 102, the terminal device 102 follows the following rules for using the time-domain resources of the SUL carrier:

[0275] (1) The terminal device can only perform SUL transmission, that is, send the first uplink signal / uplink channel to the base station, on the time-domain resources configured as U and F.

[0276] (2) If the terminal device does not receive any configuration information for the SUL carrier, the terminal device defaults that all time-domain resources of the SUL carrier are U and can be used for SUL transmission, that is, send the first uplink signal / uplink channel to the base station.

[0277] (3) For the time slots and / or symbols configured as F on the SUL carrier, the time slots and / or symbols of F can be further dynamically modified. Optionally, the time slots and / or symbols of F can be modified by SIB, RRC dedicated signaling, and DCI, and the priorities of the above three signaling for modifying the time slots and / or symbols of F are:

[0278] The priority of SIB < the priority of RRC dedicated signaling < the priority of DCI / MAC CE.

[0279] (4) If there are multiple levels of modification, after the multiple levels of modification, the terminal device can perform SUL transmission, that is, send the first uplink signal / uplink channel to the base station, on the time-domain resources finally configured as F and U, and other time-domain resources cannot be used for SUL transmission.

[0280] (5) The terminal device detects DCI related to uplink scheduling only on the relevant resources of the time-domain resources configured as F and U to determine whether to send uplink signals / uplink channels such as PUCCH, PUSCH, physical random access channel (PRACH), and sounding reference signal (SRS).

[0281] (6) When dynamically configuring the time-domain resources of the SUL carrier through DCI / MAC CE, the terminal device can ignore the configuration of the unavailable time-domain resource "D" in the table and only apply the configuration schemes of the flexible time-domain resource (F) and the uplink resource (U).

[0282] Through the above relevant definitions of the usage rules of the time-domain resources of the SUL carrier for the terminal device 102, a method for determining the time-domain resources of SUL transmission is agreed between the terminal device 102 and the base station 101, which helps to reach a consensus on SUL transmission between the base station and the terminal device and improves the reliability of transmission.

[0283] It should also be noted here that when the terminal device 102 sends the first uplink signal / uplink channel through the time-domain resources of the SUL carrier, the use of certain time-domain resources can be cancelled according to certain rules. For example, when the base station 101 dynamically configures the time-domain resources on the SUL carrier as non-uplink resources (D or F) through DCI or MAC CE, the transmission of uplink signals and / or uplink channels on the time-domain resources configured by RRC dedicated signaling can be cancelled, and the cancellation rules are as follows:

[0284] (1) When the transmission of uplink signals and / or uplink channels meets the N2 time limit requirement, the transmission of PUCCH / PUSCH on the time-domain resources configured by RRC dedicated signaling can be cancelled;

[0285] (2) For the repeated transmission of PUCCH / PUSCH configured by RRC dedicated signaling, cancel the repeated transmission of PUCCH / PUSCH in the conflicting time slots. Exemplarily, taking Figure 3 as an example, PUCCH / PUSCH is repeatedly transmitted in time slots 1 - 4, and time slot 2 is the conflicting time slot. The repeated transmission of PUCCH / PUSCH in time slot 2 can be cancelled only, and the cancellation unit is all symbols of the entire time slot 2.

[0286] (3) For the non-repeated transmission of PUCCH / PUSCH configured by RRC dedicated signaling, cancel the transmission of PUCCH / PUSCH on the entire SUL carrier. Exemplarily, taking Figure 3 as an example, it is configured to send PUCCH / PUSCH in time slot 2, and time slot 2 is the conflicting time slot. The transmission of PUCCH / PUSCH in all time slots can be cancelled.

[0287] (4) The SRS transmission configured by RRC dedicated signaling only cancels the transmission of PUCCH / PUSCH on the conflicting symbols within a certain time slot, and the cancellation unit is the conflicting symbols within the time slot.

[0288] Through the above solutions, the embodiments of the present application can configure the time-domain resources available for one or more SUL carriers. When the frequency band where the SUL carrier is located multiplexes the TDD frequency band or the low-frequency FDD frequency band, some time-domain resources of the SUL carrier may support some downlink transmissions. The embodiments of the present application configure the time-domain resources available for uplink transmission for the SUL carrier, so that the SUL transmission is not affected by services such as the downlink transmission of the SUL carrier, improving the transmission reliability and further improving the uplink transmission capacity. In addition, part of the time-domain resources of the one or more SUL carriers can be configured as dynamic or semi-static for other services to use, which can improve the resource utilization efficiency. In addition, the above embodiments also define the rules for configuring the time-domain resources of the SUL carrier for the terminal device and the rules for the terminal device to use the time-domain resources of the SUL carrier. After configuring the time-domain resources of the SUL carrier according to the above method, the terminal device can only perform SUL transmission on the available uplink resources and cancel the uplink transmission of the unavailable resources according to certain rules, further ensuring that the SUL transmission is not affected by services such as downlink transmission and improving the transmission reliability.

[0289] The above combination Figures 1 to 8 has made a detailed description of the method for determining resources in the embodiments of the present application. Next, in combination with Figures 9 to 12 a detailed description of the apparatus for determining resources in the embodiments of the present application will be given.

[0291] The sending unit 910 is configured to send first indication information to a terminal device, where the first indication information is used to indicate M time-domain resources of a first uplink carrier, where the first uplink carrier supports auxiliary uplink SUL transmission, and the M time-domain resources are the time-domain resources for SUL transmission among the N time-domain resources included in the first uplink carrier.

[0293] In a possible implementation, when the N time-domain resources include flexible resources, when the N time-domain resources include flexible time-domain resources, the first indication information is further used to indicate K of the flexible time-domain resources, where the flexible time-domain resources are used for SUL transmission or downlink transmission, K < N; and the receiving unit 920 is further configured to receive the first uplink signal and / or the uplink channel via the M time-domain resources of the first uplink carrier and the K flexible time-domain resources.

[0301] When n first uplink carriers are indicated by the downlink control information DCI, the DCI specifically indicates multiple sets of time slot configuration sets, and the multiple sets of time slot configuration sets are used to configure the n first uplink carriers. Each set of time slot configuration sets in the multiple sets of time slot configuration sets includes m single time slot pattern indexes, and m is determined according to the following formula:

[0302] K1 / K min +K2 / K min +…+K n / K min +K n+1 / K min =m

[0303] Wherein, K1, K2, …, K n , K n+1 are different reference subcarrier spacings SCS of n + 1 uplink carriers of the user equipment, and K min is the minimum reference subcarrier spacing SCS of the uplink carrier of the user equipment. The n + 1 uplink carriers include n first uplink carriers and 1 normal uplink carrier. According to K1 / K min , K2 / K min , …, K n / K min , K n+1 / K min divide the m single time slot pattern indexes to indicate the time slot configuration of n + 1 uplink carriers of the user equipment.
