[0002] In communication scenarios where users gather, the number of user terminals is huge. For dense connections in user gathering places, ensuring the communication quality of users and overcoming interference poses challenges to resource utilization and downlink control channel capacity. Due to limited downlink control channel (Physical Downlink Control Channel, PDCCH) resources, scheduling many users at the same time will increase the probability of PDCCH blocking, making it difficult to support the scheduling of all user communications. An enhanced solution that can schedule the uplink channels / downlink channels corresponding to multiple user terminals through a single downlink control information (Downlink Control Information, DCI) can reduce the PDCCH load.

[0003] A single DCI supports scheduling multiple user terminals simultaneously. However, in the actual scheduling process, the DCI may only schedule some of the multiple user terminals. Currently, a new field can be added to the DCI to indicate the actual scheduled terminal, which will lead to a large control signaling overhead. Summary of the invention

[0025] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0027] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict. It should also be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first\second\third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0028] In some embodiments, the terminal device may be referred to as User Equipment (UE). The terminal device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), etc. The terminal device may also be a smart phone, a tablet computer, a PDA, a Mobile Station (MS), a Mobile Terminal, etc. The terminal device may communicate with one or more network devices via a Radio Access Network (RAN). For example, the terminal device may be a mobile phone (or a "cellular" phone) or a computer with a terminal device, etc. For example, the terminal device may also be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges voice and / or data with a wireless access network. The terminal device may also be a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future evolving network, etc., which is not limited in the implementation of this application.

[0029] A network device is a device that provides wireless communication functions for terminal devices, including but not limited to: evolutionary base stations (eNB or e-NodeB for short), macro base stations, micro base stations (also called "small base stations"), pico base stations, base transceiver stations (BTS), base band units (BBU), access points (AP), transmission points (TP) or new generation base stations (gNodeB) in Long-Term Evolution (LTE) systems, New Radio (NR) systems or Licensed-Assisted Access using Long-Term Evolution (LAA-LTE) systems.

[0030] DCI carries the scheduling information of the cell's uplink and downlink data channels and the control information of the terminal. Different types of DCI formats contain multiple information fields, such as DCI format indication, partial bandwidth (Bandwidth Part, BWP) indication, time domain resource indication, frequency domain resource indication, modulation and coding method indication, etc. Each field in the information field has a specific meaning and occupies a different number of bits of information. The terminal device decodes the DCI through PDCCH blind detection to obtain the time domain and frequency domain resources, modulation and coding methods, antenna ports and number of layers, and other scheduling information for uplink / downlink data transmission.

[0031] DCI instructs the terminal device to receive the physical downlink shared channel (Physical Downlink Shared CHannel, PDSCH) / send the physical uplink shared channel (Physical Uplink Shared CHannel, PUSCH), and the time domain resource information is indicated by the time domain resource allocation (Time Domain Resource Allocation, TDRA). Specifically, the terminal device queries the time domain resource allocation table according to the value indicated by TDRA. The time domain resource allocation table is configured by high-level signaling or is a downlink / uplink time domain resource allocation table predefined by the protocol. The downlink time domain resource allocation table includes the time slot offset K0 between the DCI and the PDSCH it schedules, the starting symbol S and allocation length L of the PDSCH (it should be noted that the Radio Resource Control (Radio Resource Control, RRC) parameters directly indicate the starting symbol and length by configuring the Start and Length Indicator (Start and Length Indicator, SLIV)), PDSCH mapping method and other parameter information. The uplink time domain resource allocation table includes parameter information such as PUSCH mapping type, PUSCH start symbol, length SLIV value or directly indicates symbol position S and length L, and time slot offset K2 of PUSCH transmission relative to DCI.

[0032] In some communication scenarios where users gather, such as factories, stadiums, and large gatherings, a single DCI is used to schedule the uplink channels / downlink channels corresponding to multiple terminal devices. If a single DCI carries the scheduling information of multiple terminal devices, corresponding to user communications in the same scenario, multiple user terminals can be configured the same or similarly. Therefore, a part of the DCI field can be designed to schedule multiple terminals through common information fields. These fields can indicate the same configuration, or different terminals can interpret them independently according to the network side configuration. Overall, compared with multiple DCIs scheduling the uplink / downlink channels of user terminals one-to-one, signaling overhead is saved and PDCCH resource utilization is improved.

[0033] Due to the limitation of scheduling capability and DCI control signaling overhead, the number of multiple terminal devices scheduled by a single DCI is limited. For each DCI, the scheduled terminal devices may configure a candidate combination according to the maximum number, for example, supporting a single DCI to schedule terminal device 1, terminal device 2, terminal device 3 and terminal device 4 at the same time. However, in the actual scheduling process, DCI may only need to schedule some terminal devices in the combination, for example, only scheduling downlink data reception / uplink data transmission of terminal device 1 and terminal device 2. Therefore, one of the problems that need to be solved in supporting a single DCI to schedule multiple terminal devices is to effectively indicate the terminal actually scheduled in a group of candidate terminals, so that the terminal can determine whether to transmit data according to the scheduling information of the DCI during the blind detection process.

[0034] At present, an effective way is to add a new field in the DCI to indicate the terminal device that is actually scheduled. The high-level signaling configures a set of candidate scheduled terminals. The new field indicates a bitmap, and each bit of information corresponds to the identification information of a terminal device. For example, bit "1" is used to indicate that the corresponding terminal device is scheduled, and bit "0" is used to indicate that the corresponding terminal device is not scheduled this time.

[0035] The problem with the method of determining the terminal device actually scheduled by using a bitmap indication method is that a new DCI field needs to be introduced into the DCI, which increases the control signaling overhead.

[0036] To solve the above problems, the present application provides a scheduling method, such as Figure 1 As shown, applied to a terminal device, the method may include:

[0037] S101. Receive a first DCI sent by a network device, where the first DCI includes a first information field for indicating TDRA; the first information field is used to indicate whether a terminal device is scheduled and / or to indicate time domain resource information of a PDSCH / PUSCH of the terminal device.

[0038] It should be noted that the network device configures the control information carried by the first DCI. In order to maintain scheduling flexibility and full utilization of time domain resources, the network device can independently configure time domain resource information for each terminal device, that is, the time slot offset, starting symbol and symbol length of the time domain resource information corresponding to each terminal device may be the same or different. The TDRA indicating the time domain resource information can be indicated by public information or by configuring independent indication information cascade for each terminal device.

[0039] It should be noted that TDRA includes two types of fields: one is common information indicating the time domain resource information corresponding to each terminal device; the other is an independent subfield indicating the time domain resource information of each terminal device.

[0040] For the time domain resource information corresponding to each terminal device indicated by the public information, the network device needs to configure a TDRA index indication mapping table (second parameter table) to indicate the time domain resources of each actually scheduled terminal device through the public information. Each row in the table corresponds to the index value of the time domain resource allocation table (first parameter table) for multiple terminal devices to search for. Each terminal device searches the TDRA index indication mapping table based on the value indicated by the TDRA, determines the index of the corresponding time domain resource parameter allocation table, and then searches the time domain resource allocation table to determine the time domain resource parameters.

[0041] For an independent subfield indicating the time domain resource information of each terminal device, multiple subfields are cascaded in the order of the terminal set to form the first information field of TDRA, and each subfield independently indicates that the corresponding terminal device indexes a row of time domain resource parameters in the time domain resource allocation table.

[0042] In one embodiment, a terminal device receives a first parameter table configured by a network device; the first parameter table is used to indicate time domain resources, and a time slot offset parameter in the first parameter table is configured as a first value or a second value; wherein the first value is used to indicate that a terminal device indexed to a corresponding row of time domain resource parameters is not scheduled, and the second value is used to indicate a time slot offset value of PDSCH / PUSCH relative to the first DCI.

[0043] It should be noted that the network device configures a first parameter table, which includes at least one of the following parameters: resource mapping type, time slot offset value, start symbol, and length. The setting of the time slot offset parameter includes: a first value and a second value, wherein the first value is an invalid value, which is used to notify the terminal device that it is not scheduled.

[0044] It should be noted that the first value can be set to a negative number, infinity, or a defined invalid value (Invalid).

[0045] It should be noted that the second value is a value within the normal range of the time slot offset value, and is used to indicate the time slot offset value of the PDSCH / PUSCH relative to the PDCCH. The second value can be 1, 2, etc.

[0046] For an exemplary first parameter table, see Table 1. Based on Table 1, if the terminal device indexes a row of time domain resources corresponding to index 0, it indicates that the terminal device is not scheduled, and if the terminal device indexes a row of time domain resources corresponding to indexes 1 and 2, it indicates that the terminal device is scheduled.

[0047] Table 1

[0048] index Slot offset value Resource Mapping Type SLIV 0 Invalid Type A 0 1 0 Type A 45 2 0 Type A 46

[0049] In an embodiment of the present application, a terminal device receives a first parameter table configured by a network device. After the terminal device detects a first DCI, it obtains a TDRA field from the first information field, and indexes a row of time domain resource information in the first parameter table based on the value corresponding to the terminal device in the TDRA field, and checks the time slot offset value of the row of time domain resource information, and determines whether the terminal device is scheduled based on the time slot offset value.

[0050] It should be noted that, for the above two TDRA field types, there are two corresponding methods for determining whether the terminal device is scheduled.

[0051] Based on the above embodiments, in one embodiment, a second parameter table configured by a network device is received, and the second parameter table is used by a terminal device to search for an index according to an indication of a first information field; the index is used to indicate a row of time domain resource parameters in the first parameter table.

[0052] It should be noted that the terminal device searches the TDRA index indication mapping table according to the index indicated by the TDRA field, and then searches the time domain resource allocation table according to the index value of the terminal device indicated in the TDRA field index indication mapping table to determine a row of time domain resource parameters corresponding to the terminal device. If the time slot offset value is an invalid value, such as the invalid value listed above, the terminal device determines that it is not scheduled this time. If the terminal device obtains a valid time slot offset value, the terminal is actually scheduled and continues to obtain other time domain resource parameters to determine the time domain resources for its transmission information.

[0053] Based on the above embodiments, in another embodiment, the first information field is composed of multiple subfields; each subfield corresponds to a terminal device among one or more terminal devices that can be scheduled by the first DCI, and each subfield is used to indicate that the corresponding terminal device indexes a row of time domain resource parameters in the first parameter table.

[0054] It should be noted that the terminal device obtains the TDRA field information, determines the subfield corresponding to the terminal device according to the order in the terminal device set that supports scheduling by the first DCI, searches the time domain resource allocation table according to the index value indicated by the subfield, and determines a row of time domain resource parameters corresponding to the terminal device. If the time slot offset value is an invalid value, such as the invalid value listed above, the terminal device determines that it is not scheduled this time. If the terminal device obtains a valid time slot offset value, the terminal is actually scheduled, and continues to obtain other time domain resource parameters to determine the time domain resources of its PDSCH / PUSCH.

[0055] In another embodiment, the first information field is composed of multiple subfields, each subfield corresponds to a terminal device among one or more terminal devices that can be scheduled by the first DCI, and each subfield is configured as a third value or a fourth value; wherein the third value is used to indicate that the corresponding terminal device is not scheduled, and the fourth value is used to indicate that the corresponding terminal device indexes a row of time domain resource parameters in the first parameter table.

[0056] It should be noted that this method is applicable to the TDRA field type in which an independent subfield indicates the time domain resource information of each terminal device. Whether the terminal device is scheduled is indicated by indicating the TDRA subfield of invalid information.

[0057] In an embodiment of the present application, a network device configures a time domain resource allocation table, which includes parameters such as resource mapping type, time slot offset value, starting symbol and length.

[0058] In an embodiment of the present application, the network device determines several terminal devices that are actually scheduled among one or more terminal devices that can be scheduled by the first DCI, and notifies the terminal whether it is scheduled by indicating a valid value / invalid value in the first information field of the TDRA.

[0059] Exemplarily, if the set of terminal devices that can be scheduled simultaneously by the first DCI configured by the network device is {terminal device 1, terminal device 2, terminal device 3, terminal device 4}, the TDRA field is composed of 4 subfields corresponding to 4 terminal devices cascaded, and the bit length of each subfield is determined according to the number of rows in the time domain resource allocation table, which is assumed to be N. The network device defines an invalid value, for example, a subfield of length N indicates a value of all 0 or all 1, which means that the subfield is invalid, and the invalid subfield is used to indicate that the terminal device is not scheduled. Other values ​​indicated by the subfield are considered valid and are used to indicate a row of time domain resource information in the time domain resource allocation table.

[0060] See Table 2 for an example, which is the first information field in the first DCI for indicating TDRA.

[0061] Table 2

[0062] 0000 0010 0110 1001 Terminal device 1 Terminal device 2 Terminal device 3 Terminal device 4

[0063] Based on Table 2, it can be seen that the subfield corresponding to terminal device 1 is all 0, indicating that terminal device 1 is not scheduled in this round, while terminal device 2, terminal device 3, and terminal device 4 are all scheduled in this round.

[0064] In the example of the present application, the terminal device detects the first DCI, obtains the first information field used to indicate TDRA, obtains the corresponding TDRA subfield according to the order in the set of terminal devices that support simultaneous scheduling of the first DCI, and determines whether to be scheduled according to whether the value indicated by the subfield is a valid value. If it is an invalid value, it is not scheduled; if it is a valid value, the time domain resource allocation table is searched according to the index indicated by the subfield to determine the corresponding time domain resource information.

[0065] It can be understood that TDRA is used to indicate the time domain resource information corresponding to multiple terminal devices supported by the first DCI for scheduling. By multiplexing the first information field indicating TDRA in the first DCI to indicate the terminal devices actually scheduled, the scheduling of the terminal devices can be dynamically indicated while retaining the original function of DCI, thereby saving the overhead of control signaling.

[0066] The present application also proposes a scheduling method, such as Figure 2 As shown, applied to a network device, the method includes:

[0067] S201. Send a first DCI to a terminal device, where the first DCI includes a first information field for indicating TDRA; the first information field is used to indicate whether the terminal device is scheduled and / or indicate time domain resource information of PDSCH / PUSCH of the terminal device.

[0068] In one embodiment, a network device configures a first parameter table for a terminal device; the first parameter table is used to indicate time domain resources, and a time slot offset parameter in the first parameter table is configured as a first value or a second value; wherein the first value is used to indicate that a terminal device indexed to a corresponding row of time domain resource parameters is not scheduled, and the second value is used to indicate a time slot offset value of PDSCH / PUSCH relative to the first DCI.

[0069] Based on the above embodiments, in one embodiment, the network device configures a second parameter table for the terminal device, the second parameter table is used by the terminal device to search for an index according to the first information field, and the index is used to indicate a row of time domain resource parameters in the first parameter table.

[0070] Based on the above embodiments, in another embodiment, the first information field is composed of multiple subfields; each subfield corresponds to a terminal device among one or more terminal devices that can be scheduled by the first DCI, and each subfield is used to indicate that the corresponding terminal device indexes a row of time domain resource parameters in the first parameter table.

[0071] In the embodiment of the present application, the first parameter table includes at least one of the following parameters: resource mapping type, time slot offset value, start symbol, length. The specific parameters can be selected according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0072] In another embodiment, the first information field is composed of multiple subfields, each subfield corresponds to a terminal device among one or more terminal devices that can be scheduled by the first DCI, and each subfield is configured as a third value or a fourth value; wherein the third value is used to indicate that the corresponding terminal device is not scheduled, and the fourth value is used to indicate that the corresponding terminal device indexes a row of time domain resource parameters in the first parameter table.

[0073] It should be noted that S201 is a step executed by the network device corresponding to S101. For a specific description, please refer to S101 and will not be repeated here.

[0074] It can be understood that TDRA is used to indicate the time domain resource information corresponding to multiple terminal devices supported by the first DCI for scheduling. By multiplexing the first information field indicating TDRA in the first DCI to indicate the terminal devices actually scheduled, the scheduling status of the terminal devices can be dynamically indicated while retaining the original function of DCI, thereby saving the overhead of control signaling.

[0075] The present application embodiment provides a terminal device. Figure 3 As shown, the terminal device 1 includes:
