Description

[0001] This application claims the priority of an international patent application filed with the China Patent Office on January 10, 2018, with application number PCT / CN2018 / 072169 and invention name “Method for sending data, method for receiving data, terminal device and network device”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The embodiments of the present invention relate to the field of communications, and more specifically, to a method for sending data, a method for receiving data, a terminal device, and a network device. Background Art

[0003] At present, the fifth generation mobile communication technology (5-Generation, 5G) New Radio (New Radio, NR) system has introduced inter-slot frequency hopping and intra-slot frequency hopping. In addition, intra-slot frequency hopping has been discussed quite thoroughly, but there is basically no clear conclusion on inter-slot frequency hopping. Therefore, the current intra-slot frequency hopping does not work.

[0004] In addition, 5G also introduces Ultra-Reliable and Low Latency Communication (URLLC), which is characterized by ultra-high reliability (for example, 99.999%) transmission within extreme latency (for example, 1ms). In order to achieve this goal, the concept of Grant free was proposed. Grant free adopts a pre-configured / semi-permanent resource configuration method, and the terminal can transmit on the configured resources according to business needs. This technology avoids the process of resource request (Schedule request, SR) and buffer status report (Buffer status report, BSR), and increases the effective transmission time of the terminal.

[0005] However, in unlicensed transmission, the location where the user initiates the transmission is relatively flexible, including a fixed location and an arbitrary location. Since the arbitrary location is used, the access user cannot be controlled, so the access user interference problem must also be considered in the design of frequency hopping. For example, if the terminal device uses non-slot transmission, such as Figure 1 As shown, the actual transmission of the terminal may only occur in the same frequency domain resource, which cannot guarantee that non-time slot transmission obtains frequency diversity gain, and may also cause the transmission resources of multiple terminals to overlap, thereby causing user conflicts. Summary of the invention

[0010] In addition, since the terminal device determines the target resource based on the configuration information, it can increase the randomness of interference as much as possible to avoid constant or frequent conflicts with the same user. Therefore, when the DMRS of the terminal device conflicts with other terminals, it can effectively improve the performance of user identification and improve the system transmission efficiency.

[0056] Figure 2 It is a schematic diagram of a 5G application scenario of an embodiment of the present invention.

[0057] like Figure 2 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0058] It should be understood that the embodiment of the present invention is only exemplified by the 5G communication system 100, but the embodiment of the present invention is not limited thereto. That is to say, the technical solution of the embodiment of the present invention can be applied to various scenarios including 5G communication systems. For example, a hybrid deployment scenario consisting of a 5G communication system and a first communication system, and the like. Among them, the first communication system can be any communication system. For example: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), etc.

[0059] Furthermore, the present invention describes various embodiments in conjunction with network devices and terminal devices.

[0060] The network device 120 may refer to any entity on the network side that is used to send or receive signals, for example, a base station device in a 5G network.

[0061] The terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more core networks via a radio access network (RAN), and may also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), 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, etc.

[0062] Figure 3 It is a schematic flow chart of a method for sending data according to an embodiment of the present invention.

[0063] Specifically, if Figure 3 As shown, the method includes:

[0064] 210. The terminal device determines a target resource based on a time index and / or configuration information.

[0065] 220. The terminal device sends data to the network device on the target resource.

[0066] Specifically, the terminal device can directly determine the target resource based on the time index, or the terminal device can determine the target resource through configuration information sent by the network device. Then, the terminal device sends data to the network device on the target resource. Furthermore, the configuration information includes information for the terminal device to determine the target resource based on the time index.

[0067] Further, if the terminal device determines the target resource based on the configuration information, before the terminal device determines the target resource based on the configuration information, the terminal device receives the configuration information sent by the network device, and the configuration information is exclusive information of the terminal device. Thus, the terminal device determines the target resource based on the configuration information. The network device may also determine the target resource based on the configuration information and receive data sent by the terminal device on the target resource.

[0068] In other words, the network device determines configuration information used by the terminal device to determine the target resource based on the time index, and the configuration information is exclusive information of the terminal device. Before the network device determines the target resource based on the configuration information, the network device sends the configuration information to the terminal device.

[0069] Specifically, if Figure 4 As shown, the process of interaction between the network device and the terminal device in the embodiment of the present application includes:

[0070] 310, the network device determines configuration information.

[0071] 320. The network device sends the configuration information to the terminal device.

[0072] 330. The network device determines the target resource based on the configuration information.

[0073] 340. The network device receives data on the target resource.

[0074] It should be understood that in the embodiment of the present application, the time index can be understood as an index of a time unit, wherein the time unit can be understood as a period of time. However, the embodiment of the present application does not specifically limit the length of this period of time.

[0075] For example, in one embodiment, the unit of the time unit corresponding to the time index includes at least one of the following: at least one symbol, at least one time slot, and at least one transmission opportunity. Specifically, for example, the unit of the time unit corresponding to the time index may be a symbol, or a time period consisting of multiple symbols, or 1 time slot, or a time period consisting of multiple time slots.

[0076] Furthermore, the unit of the time unit corresponding to the time index is determined by the high-layer signaling or physical layer signaling sent by the terminal device through the network device.

[0077] For example, the unit of the time unit corresponding to the time index may be directly indicated by the network device, or may be indirectly indicated by the network device, or may be specified by a protocol, and this application does not make any specific limitation.

[0078] Furthermore, the time unit involved in the embodiments of the present application may refer to a relative time unit or an absolute time unit, and the embodiments of the present application do not make any specific limitations.

[0079] Since the terminal device in the embodiment of the present application directly determines the target resource based on the time index, the terminal device can control the resource granularity of the target resource to meet the transmission requirements of the terminal device, and thus, can avoid the actual data transmission process occurring only on the same frequency domain resource, thereby further improving the frequency diversity gain in non-time slot transmission.

[0080] In addition, since the terminal device determines the target resource based on the configuration information, it can increase the randomness of interference as much as possible to avoid constant or frequent conflicts with the same user. Furthermore, when the demodulation reference signal (DMRS) of the terminal device conflicts with other terminals, it can effectively improve the performance of user identification and improve the system transmission efficiency.

[0081] It should be noted that in the embodiment of the present application, the terminal device can directly determine the target resource based on the time index, and then control the resource granularity of the target resource. The terminal device can also directly control the resource granularity of the target resource based on the configuration information and determine the target resource, and avoid resource conflicts. However, the embodiment of the present application does not specifically limit the implementation method of determining the target resource.

[0082] For example, the terminal device may also determine the target resource according to the number of data transmissions, that is, the terminal device determines the resource location of the target resource based on the number of data transmissions.

[0083] The following is an exemplary description of the implementation method in which the terminal device determines the target resource based on the configuration information in the embodiment of the present application:

[0084] In one embodiment, the configuration information includes at least one of the following information:

[0085] The first frequency hopping parameter RB start , the second frequency hopping parameter RB offset , the number of available resources N, the frequency hopping parameter K and the demarcation point parameter B, where the RB start Indicates the starting resource location. offset The terminal device is used to obtain the next hop resource location. Thus, the terminal device can obtain the target resource based on each parameter information in the configuration information.

[0086] It should be understood that in the embodiments of the present application, the implementation method of determining the target resource based on the configuration information is applicable to both the terminal device side and the network device side. Therefore, in order to avoid repetition, the terminal device side is used as an example for exemplary description below.

[0087] The following is an exemplary description of a specific implementation method in which the terminal device determines the target resource based on the parameters in the above configuration information:

[0088] In one embodiment, the terminal device may determine the target resource according to formula (1):

[0089]

[0090] Wherein, RB(n) represents the target resource, mod represents the modulus operation, represents the size of the bandwidth portion, and n represents the time index.

[0091] Specifically, Figure 5 As shown, since the resource granularity of the target resource is based on the time unit corresponding to the time index, it is possible to avoid that the actual data transmission process only occurs on the same frequency domain resource, and further improve the frequency diversity gain in non-time slot transmission. It should be understood that when the target resource is determined using the above formula (1), the configuration information may include the first frequency hopping parameter RB start and / or the second frequency hopping parameter RB offset .

[0092] In another embodiment, the terminal device may determine the target resource according to formula (2):

[0093]

[0094] Wherein, RB(n) represents the target resource, mod represents the modulus operation, represents the size of the bandwidth portion, and n represents the time index.

[0095] Specifically, Figure 6 As shown, the unit of the time unit is a transmission opportunity. It should be understood that when the target resource is determined using the above formula (2), the configuration information may include the first frequency hopping parameter RB start and / or the second frequency hopping parameter RB offset .

[0096] In another embodiment, the terminal device may determine the target resource according to formula (3):

[0097]

[0098] Wherein, RB(n) represents the target resource, mod represents the modulus operation, represents the size of the bandwidth portion, and n represents the time index.

[0099] It should be understood that when the target resource is determined using the above formula (3), the configuration information may include the first frequency hopping parameter RB start , the second frequency hopping parameter RB offsetand any one of the number N of available resources.

[0100] For example, suppose RB in the configuration information of user 1 offset =2, the number of available resources N = 2. In the configuration information of user 2, RB offset =1, the number of available resources N = 3. Figure 7 As shown, the probability of resource conflict between user 1 and user 2 can be effectively reduced.

[0101] Furthermore, in the embodiment of the present application, N may be greater than or equal to 2.

[0102] For another example, the terminal device may determine the target resource according to formula (4):

[0103]

[0104] Wherein, RB(n) represents the target resource, mod represents the modulo operation, ceiling() represents the integer operation, represents the size of the bandwidth portion, and n represents the time index.

[0105] It should be understood that when the target resource is determined using the above formula (4), the configuration information may include the first frequency hopping parameter RB start , the second frequency hopping parameter RB offset and any one of the cut-off point parameters B.

[0106] For example, assume that the configuration information in the embodiment of the present application includes a demarcation point parameter B, and B=1 in the configuration information of user 1. B=2 in the configuration information of user 2. Figure 8 As shown, the probability of resource conflict between user 1 and user 2 can be effectively reduced.

[0107] For another example, the terminal device may determine the target resource according to formula (5):

[0108]

[0109] Wherein, RB(n) represents the target resource, mod represents the modulus operation, represents the size of the bandwidth portion, and n represents the time index.

[0110] It should be understood that when the target resource is determined using the above formula (5), the configuration information may include the first frequency hopping parameter RB start , the second frequency hopping parameter RB offset and any one of the frequency hopping parameters K.

[0111] Here, K may be implicitly or explicitly configured by the network device.

[0112] For example, K is equal to the number of repeated transmissions of the data.

[0113] Furthermore, if the terminal device is not configured with the number of repeated transmissions of the data, the K may default to being equal to the first value; if the terminal device is configured with the number of repeated transmissions of the data, the K may be equal to the number of repeated transmissions of the data.

[0114] For example, if the terminal device is not configured with the number of repeated transmissions of the data, K may be defaulted to be equal to 2; if the terminal device is configured with the number of repeated transmissions of the data, K is equal to the number of repeated transmissions of the data.

[0115] It should also be understood that the above formulas (1), (2), (3), (4) and (5) are merely exemplary descriptions of the terminal device determining the target resource based on the frequency modulation parameters in the configuration information in the embodiment of the present application. The manner in which the terminal device determines the target resource based on the configuration information in the embodiment of the present application is not limited to the above formulas.

[0116] In another embodiment, the configuration information includes the location information of the target resource, so that the terminal device can directly send data to the network device based on the location information of the target resource.

[0117] For example, it is assumed that the configuration information in the embodiment of the present application includes a series of transmission resources. Fig. 9 As shown, assuming that user 1 is configured with {RB_1, RB_3, RB_1, RB_3, RB_1}, and user 2 is configured with {RB_3, RB_1, RB_2, RB_1, RB_3}, the method of the embodiment of the present application can effectively reduce the probability of resource conflict between user 1 and user 2, or even eliminate the conflict.
