Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method and apparatus for determining time-domain resources, and a computer storage medium. Background Technology

[0002] In Long Term Evolution (LTE) systems, uplink and downlink configurations are statically determined by the frame structure, and the time-domain resource scheduling of data channels (such as Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH)) follows the uplink and downlink configurations of the frame structure.

[0003] In the fifth generation (5G, 5 th In 5G New Radio (NR) systems, to improve resource allocation flexibility and reduce latency, the uplink and downlink configurations for each time slot can be configured semi-statically or even dynamically. Meanwhile, to improve coverage at cell edges, 5G NR will support multi-slot scheduling, where the base station allocates resources from multiple time slots to the terminal at once, improving signal coverage through energy accumulation in the time domain.

[0004] In addition, in 5G NR systems, some time slots or symbols can be configured as "undetermined" (or flexible), meaning that it is not yet certain whether they are used for downlink or uplink transmission, and they can be scheduled as downlink or uplink as needed when scheduling resources.

[0005] In multi-slot scheduling, to limit the overhead of control signaling, the same symbols are assigned to each slot. The terminal determines whether a slot is to be used for multi-slot scheduling based on whether it contains enough symbols consistent with the transmission direction of the resource allocation. However, there is no clear scheme for whether "undetermined" symbols (or flexible symbols) are used for multi-slot scheduling, making it impossible to simultaneously achieve coverage enhancement and large user capacity in a system.

[0085] If flexible symbols (or undetermined symbols) are allowed for transmission in multi-slot scheduling, then in order to avoid interference between different transmission directions, terminals in the same cell or terminals in adjacent cells must also schedule the same transmission direction on the corresponding flexible symbols. This limits the flexibility of scheduling and is not conducive to achieving high spectral efficiency in scenarios with a large number of terminals.

[0086] If flexible symbols (or undetermined symbols) are not allowed to be used for multi-slot scheduling transmissions, the number of slots that conform to multi-slot scheduling will be greatly reduced, making it difficult to use multi-slot scheduling effectively and limiting the coverage enhancement capabilities at the cell edge.

[0087] To address this, this invention proposes a time-domain resource determination method that allows for the use or non-use of time-domain resources with flexible transmission directions based on network device instructions, enabling greater coverage or scheduling flexibility for different application scenarios.

[0088] Figure 1This is a flowchart illustrating the time-domain resource determination method according to an embodiment of the present invention. Figure 1 ,like Figure 1 As shown, the time-domain resource determination method includes the following steps:

[0089] Step 101: The terminal receives first indication information sent by the network device. The first indication information is used to indicate whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information, whether the first time domain resource determination rule or the second time domain resource determination rule is used.

[0090] In this embodiment of the invention, the terminal can be any device capable of communicating with network devices, such as a mobile phone, tablet computer, laptop computer, or desktop computer.

[0091] In this embodiment of the invention, the network device refers to a base station, such as a gNB in ​​a 5G system or an eNB in ​​a 4G system.

[0092] In this embodiment of the invention, the terminal receiving the first indication information sent by the network device can be achieved through any of the following methods:

[0093] 1) The terminal receives the SI sent by the network device, wherein the SI includes the first indication information.

[0094] 2) The terminal receives the RRC signaling sent by the network device, wherein the RRC includes the first indication information.

[0095] 3) The terminal receives the DCI sent by the network device, and the DCI includes the first indication information.

[0096] 4) The terminal receives a MAC CE sent by the network device, wherein the MAC CE includes the first indication information.

[0097] In this embodiment of the invention, the first indication information is used to indicate whether a first time-domain resource determination rule or a second time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information. For example, the first indication information is represented by one bit. When the bit is 1, it indicates that the first time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information; when the bit is 0, it indicates that the second time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information. Of course, it is also possible that when the bit is 1, it indicates that the second time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information; when the bit is 0, it indicates that the first time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information.

[0098] The first time-domain resource determination rule and the second time-domain resource determination rule are described below.

[0099] Assuming the first scheduling information schedules N symbols for the first transmission direction in at least one time slot, where N is a positive integer, then:

[0100] The first time-domain resource determination rule is: if the transmission direction of all N symbols in the first time slot is configured as the first transmission direction, then the terminal determines that the first time slot can be used for transmission of the first channel;

[0101] The second time-domain resource determination rule is as follows: if all N symbols in the first time slot are configured for the first transmission direction and / or the flexible transmission direction, then the terminal determines that the first time slot can be used for transmission in the first channel.

[0102] In the above scheme, the first time slot refers to a specific time slot in general.

[0103] For the first time-domain resource determination rule, the transmission directions of all N symbols in a certain time slot need to be configured as the first transmission direction (that is, the transmission direction of the first channel scheduled by the first scheduling information). It can be seen that flexible symbols cannot be used as resources for multi-time-slot scheduling.

[0104] For the second time-domain resource determination rules, there are three cases:

[0105] Case 1: The transmission direction of all N symbols in a certain time slot is configured as the first transmission direction (that is, the transmission direction of the first channel scheduled by the first scheduling information).

[0106] Scenario 2: The transmission directions of all N symbols in a certain time slot are configured as flexible transmission directions (that is, the N symbols are flexible symbols that can be used for uplink or downlink scheduling).

[0107] Scenario 3: In a certain time slot, the transmission direction of N symbols is partially configured as the first transmission direction, and the rest are all configured as flexible transmission directions.

[0108] It is evident that flexible symbols can be used as a resource for multi-slot scheduling.

[0109] In this embodiment of the invention, the first transmission direction is either the uplink transmission direction or the downlink transmission direction.

[0110] In this embodiment of the invention, the first scheduling information is carried in DCI or RRC signaling.

[0111] In this embodiment of the invention, the terminal determines the transmission direction of the N symbols in the first time slot in the following manner:

[0112] The terminal obtains first configuration information, which is used to configure the transmission direction of each symbol in at least one time slot, including the first time slot; the terminal determines the transmission direction of the N symbols in the first time slot based on the first configuration information.

[0113] In one embodiment, the terminal obtains the first configuration information based on pre-configured information.

[0114] In one embodiment, the terminal obtains the first configuration information from the SI sent by the network device.

[0115] In one embodiment, the terminal obtains the first configuration information from the RRC signaling sent by the network device.

[0116] In one embodiment, the terminal obtains the first configuration information from the downlink control information (DCI) sent by the network device.

[0117] In one embodiment, the terminal may determine the first configuration information based on a combination of any information in SI, RRC signaling, and DCI.

[0118] Step 102: The terminal determines the time-domain resource determination rule to be adopted according to the first indication information, and determines at least one time slot for transmitting the first channel based on the adopted time-domain resource determination rule.

[0119] Step 103: The terminal transmits the first channel with the network device in the determined at least one time slot.

[0120] In this embodiment of the invention, the terminal transmitting the first channel with the network device in the determined at least one time slot includes the following two cases:

[0121] 1) Uplink transmission: The terminal transmits the first channel to the network device in the determined at least one time slot.

[0122] 2) Downlink transmission: The terminal receives the first channel sent by the network device in the determined at least one time slot.

[0123] The technical solutions of this invention can be optimized according to various application scenarios to improve the overall system's spectral efficiency. For example, in urban scenarios, where there are many users in a cell but a small cell radius, strong coverage is not required, so the first time-domain resource determination rule can be used. As another example, in suburban scenarios, where there are fewer users in a cell but a larger cell radius, strong coverage is required, so the second time-domain resource determination rule can be used.

[0124] Figure 2 This is a flowchart illustrating the time-domain resource determination method according to an embodiment of the present invention. Figure 2 ,like Figure 2 As shown, the time-domain resource determination method includes the following steps:

[0125] Step 201: The network device sends a first indication information to the terminal. The first indication information is used to indicate whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information, whether the first time domain resource determination rule or the second time domain resource determination rule is used.

[0126] In this embodiment of the invention, the terminal can be any device capable of communicating with network devices, such as a mobile phone, tablet computer, laptop computer, or desktop computer.

[0127] In this embodiment of the invention, the network device refers to a base station, such as a gNB in ​​a 5G system or an eNB in ​​a 4G system.

[0128] In this embodiment of the invention, the network device sends the first indication information to the terminal, which can be achieved through any of the following methods:

[0129] 1) The network device sends an SI to the terminal, the SI including the first indication information.

[0130] 2) The network device sends an RRC signaling message to the terminal, wherein the RRC message includes the first indication information.

[0131] 3) The network device sends a DCI to the terminal, the DCI including the first indication information.

[0132] 4) The network device sends a MAC CE to the terminal, and the MAC CE includes the first indication information.

[0133] In this embodiment of the invention, the first indication information is used to indicate whether a first time-domain resource determination rule or a second time-domain resource determination rule is used to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information. Assuming that the first scheduling information schedules N symbols for the first transmission direction in at least one time slot, where N is a positive integer, then:

[0134] The first time-domain resource determination rule is: if the transmission direction of all N symbols in the first time slot is configured as the first transmission direction, then the terminal determines that the first time slot can be used for transmission of the first channel;

[0135] The second time-domain resource determination rule is as follows: if all N symbols in the first time slot are configured for the first transmission direction and / or the flexible transmission direction, then the terminal determines that the first time slot can be used for transmission in the first channel.

[0136] In this embodiment of the invention, the first transmission direction is either the uplink transmission direction or the downlink transmission direction.

[0137] In this embodiment of the invention, the first scheduling information is carried in DCI or RRC signaling.

[0138] In this embodiment of the invention, in order to let the terminal know the transmission direction of the N symbols in the first time slot, the network device sends first configuration information to the terminal. The first configuration information is used to configure the transmission direction of each symbol in at least one time slot, including the first time slot.

[0139] In this embodiment of the invention, the network device sends first configuration information to the terminal, including:

[0140] The network device sends an SI to the terminal, the SI including the first configuration information; and / or,

[0141] The network device sends an RRC to the terminal, the RRC including the first configuration information; and / or,

[0142] The network device sends a DCI to the terminal, and the DCI includes the first configuration information.

[0143] Step 202: The network device transmits the first channel with the terminal in at least one time slot scheduled by the first scheduling information corresponding to the first indication information.

[0144] In this embodiment of the invention, the network device transmits the first channel with the terminal in at least one time slot scheduled by the first scheduling information corresponding to the first indication information, including the following two cases:

[0145] 1) Uplink transmission: The network device receives the first channel sent by the terminal in at least one time slot scheduled by the first scheduling information corresponding to the first indication information.

[0146] 2) Downlink transmission: The network device transmits the first channel to the terminal in at least one time slot scheduled by the first scheduling information corresponding to the first indication information.

[0147] The technical solutions of the embodiments of the present invention will be further described in detail below with reference to specific examples.

[0148] Example 1: Using the first time-domain resource determination rule to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information.

[0149] Reference Figure 3 The first channel is the downlink channel. The network equipment schedules four time slots for the terminal to transmit on the first channel, with each time slot containing a portion of symbols (…). Figure 3 Symbols 2-10 are scheduled for transmission in the first channel. Based on the first time-domain resource determination rule, only time slots where symbols 2-10 are downlink symbols are available for transmission in the first channel. Figure 3 In the example, symbols 2-10 in time slots 0 and 1 are downlink symbols, which meet the requirements. However, symbols 2-10 in time slot 2 are undetermined symbols, which do not meet the requirements. Symbols 2-10 in time slot 3 are uplink symbols, which also do not meet the requirements. Therefore, time slots 0 and 1 can be used for transmission on the first channel, while the latter two time slots scheduled for the first channel can only be mapped to subsequent time slots with sufficient downlink resources, namely time slots 5 and 6.

[0150] Example 2: Using the second time-domain resource determination rule to determine whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information.

[0151] Reference Figure 4 The first channel is the downlink channel. The network equipment schedules four time slots for the terminal to transmit on the first channel, with each time slot containing a portion of symbols (…). Figure 4 Symbols 2-10 are scheduled for transmission in the first channel. Based on the second time-domain resource determination rule, only time slots containing downlink symbols and / or undetermined symbols (symbols 2-10) are available for transmission in the first channel. Figure 4 In the example, symbols 2-10 in time slots 0 and 1 are downlink symbols, which meet the requirements. Symbols 2-10 in time slot 2 are undetermined symbols, which also meet the requirements. Symbols 2-10 in time slot 3 are uplink symbols, which do not meet the requirements. Therefore, time slots 0, 1, and 2 can be used for transmission on the first channel, and the last time slot scheduled for the first channel can only be mapped to a subsequent time slot with sufficient downlink resources, i.e., time slot 5.

[0152] Figure 5 This is a schematic diagram of the structural composition of the time-domain resource determination device according to an embodiment of the present invention. Figure 1 In this embodiment, the time-domain resource determination device is applied to the terminal side, such as... Figure 5 As shown, the time-domain resource determination device includes:

[0153] The receiving unit 501 is used to receive first indication information sent by the network device. The first indication information is used to indicate whether the first time slot is used for transmission of the first channel scheduled by the first scheduling information, whether the first time domain resource determination rule or the second time domain resource determination rule is used to determine the first time slot.

[0154] The first determining unit 502 is used to determine the time-domain resource determination rule to be adopted based on the first indication information;

[0155] The second determining unit 503 is used to determine at least one time slot for transmitting the first channel based on the adopted time-domain resource determining rules;

[0156] Transmission unit 504 is configured to transmit the first channel with a network device in the determined at least one time slot.
