[0002] The Scheduling Request (SR) is used to notify the base station to allocate corresponding uplink transmission resources to the uplink data in the terminal device.

[0003] In a Long Term Evolution (LTE) system, if a user equipment (UE) needs to send uplink data to an eNB, the UE first uses a pre-configured physical uplink control channel (PUCCH) physical resource to send an SR to the eNB. The eNB configures uplink transmission resources to the UE according to the SR, so that the UE sends uplink data to the eNB according to the uplink transmission resources configured by the eNB.

[0004] In the above method, the eNB pre-configures dedicated physical resources for each UE to transmit the SR. The current LTE system does not make high use of these dedicated physical resources. Summary of the invention

[0072] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0073] The words "first", "second" and similar terms mentioned herein do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, the words "a" or "an" and similar terms do not indicate a quantity limitation, but indicate the existence of at least one. The words "connected" or "connected" and similar terms are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0074] The "module" mentioned in this article generally refers to a program or instruction stored in the memory that can implement certain functions; the "unit" mentioned in this article generally refers to a functional structure divided according to logic, and the "unit" can be implemented by pure hardware, or a combination of software and hardware.

[0075] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0076] In the related art, a terminal device uses multiple uplink logical channels for data transmission, and a logical channel is a channel that the Media Access Control (MAC) layer provides services to the Radio Link Control (RLC) layer. When there is an uplink logical channel for uplink data to be sent in the terminal device, the terminal device needs to send an SR to the base station, and the SR is used to indicate to the base station that there is an uplink logical channel for uplink data to be sent in the terminal device, or in other words, the SR is used to indicate to the base station which uplink logical channels have uplink data to be sent. Therefore, the base station sends configuration information to the terminal device in advance, and the configuration information is used to configure the physical resources for transmitting the SR to the terminal device. Among them, the physical resource is a 2-bit physical resource, and the SR is a 2-bit information. Correspondingly, the terminal device uses the 2-bit physical resource to transmit the SR, and the value of the SR corresponds to the uplink logical channel.

[0077] Optionally, there is a one-to-one correspondence between the value of SR and the uplink logical channel. Schematically, assuming that there are 4 uplink logical channels, the correspondence is shown in Table 1. SR has 4 values: "00", "01", "10" and "11". When the value of SR is "00", it is used to indicate that there is uplink data to be sent in the uplink logical channel 1 in the terminal device. When the value of SR is "01", it is used to indicate that there is uplink data to be sent in the uplink logical channel 2 in the terminal device. When the value of SR is "10", it is used to indicate that there is uplink data to be sent in the uplink logical channel 3 in the terminal device. When the value of SR is "11", it is used to indicate that there is uplink data to be sent in the uplink logical channel 4 in the terminal device.

[0080]

[0081] In the above method, the base station pre-configures a dedicated physical resource for the terminal device to transmit the SR, and the physical resource can be a PUCCH resource. The current LTE system does not make high use of these dedicated physical resources. Based on this technical problem, the present invention provides an uplink control information transmission method, device and system. Figures 1 to 5 Method embodiments are provided.

[0082] First, several terms involved in the embodiments of the present invention are introduced.

[0083] 1. Uplink Control Information (UCI): includes SR and uplink information.

[0084] 2. First scheduling request: used to indicate an uplink logical channel among multiple uplink logical channels that has data to be sent. The first scheduling request is used to specifically indicate to the base station which uplink logical channels have data to be sent. The uplink logical channels with data to be sent are a subset of all uplink logical channels in the terminal. Optionally, in an embodiment of the present invention, the first scheduling request is a scheduling request that needs to be sent within a target time unit but is not actually sent.

[0085] 3. Second scheduling request: used to indicate whether there is uplink data to be sent in multiple uplink logical channels. The second scheduling request does not necessarily indicate to the base station which uplink logical channels have data to be sent, but may only indicate to the base station that there is uplink data to be sent in the terminal. Optionally, in an embodiment of the present invention, the second scheduling request is a scheduling request actually sent and / or implicitly indicated by the terminal device on the physical resources within the target time unit, or is a scheduling request corresponding to the physical resource determined by the access network device when receiving uplink information on the physical resources within the target time unit.

[0086] 4. Uplink information: including at least one of feedback response information, channel state information (CSI) and uplink service data. Among them, feedback response information includes confirmation response (ACK) and non-confirmation response (NACK). ACK is used to indicate that the access network device has correctly received the uplink data sent by the terminal device, and NACK is used to indicate that the access network device has not correctly received the uplink data sent by the terminal device; CSI refers to the channel state information of the uplink channel transmitted by the terminal device to the base station, which is used to indicate the channel state of the uplink channel of the terminal device.

[0087] Some of the related terms involved in the embodiments of the present invention may refer to the corresponding related descriptions in the 3GPP protocol, such as ACK / NACK, CSI and uplink service data, etc., which will not be repeated herein.

[0088] Please refer to Figure 1 , which shows a schematic diagram of the structure of a mobile communication system provided by an exemplary embodiment of the present invention. The mobile communication system may be an LTE system or a 5G system, which is also called a New Radio (NR) system, and is not limited in this embodiment. The mobile communication system includes: an access network device 120 and a terminal device 140.

[0089] The access network device 120 may be a base station, which may be used to convert received wireless frames and IP packet messages to each other, and may also coordinate the attribute management of the air interface. For example, the base station may be an evolutionary Node B (eNB or e-NodeB) in LTE, or a base station using a centralized distributed architecture in a 5G system. When the access network device 120 adopts a centralized distributed architecture, it generally includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical layer (PHY) protocol stack. The embodiment of the present invention does not limit the specific implementation of the access network device 120. Optionally, the access network device may also include a home base station (HeNB), a relay, a micro base station Pico, and the like.

[0090] The access network device 120 and the terminal device 140 establish a wireless connection through a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on the 5G standard, such as the wireless air interface is a new air interface (New Radio, NR); or, the wireless air interface may also be a wireless air interface based on the next generation mobile communication network technology standard of 5G; or, the wireless air interface may also be a wireless air interface based on the 4G standard (LTE system). The access network device 120 may receive uplink data sent by the terminal device 140 through a wireless connection.

[0091] The terminal device 140 may refer to a device that performs data communication with the access network device 120. The terminal device 140 may communicate with one or more core networks via a radio access network (RAN). The terminal device 140 may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device. For example, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile station (Mobile), a remote station (Remote Station), an access point (Access Point), a remote terminal device (Remote Terminal), an access terminal device (Access Terminal), a user terminal (User Terminal), a user agent (User Agent), a terminal device (User Device), or a user terminal device (User Equipment, UE). Optionally, the terminal device 140 may also be a relay device, which is not limited in this embodiment. The terminal device 140 may send uplink data to the access network device 120 through a wireless connection with the access network device 120.

[0092] Optionally, the access network device 120 pre-configures physical resources within the target time unit to the terminal device 140. When the terminal device 140 needs to send a first scheduling request and uplink information within the target time unit, the terminal device 140 simultaneously sends the uplink information and the second scheduling request to the access network device 120 on the physical resources within the target time unit.

[0093] It should be noted that in Figure 1 The mobile communication system shown may include multiple access network devices 120 and / or multiple terminal devices 140. Figure 1 An access network device 120 and a terminal device 140 are shown as an example, but this embodiment is not limited to this.

[0094] In order to make full use of the physical resources used to send SR, the embodiment of the present invention uses the physical resources used to send the first scheduling request to send the second scheduling request and other uplink information at the same time, or uses the physical resources used to send other uplink information to send the second scheduling request and other uplink information at the same time, thereby achieving the effect of indicating SR to the access network device and sending other uplink information at the same time.

[0095] Please refer to Figure 2, which shows a flowchart of an uplink control information transmission method provided by an exemplary embodiment of the present invention. This embodiment uses the method for Figure 1 The method is described in the mobile communication system shown in FIG.

[0096] Step 201: The access network device configures physical resources within a target time unit for the terminal device.

[0097] Optionally, the access network device sends configuration information to the terminal device, where the configuration information is used to configure physical resources within the target time unit for the terminal device. The physical resources are used to send the first scheduling request and / or uplink information.

[0098] Optionally, the target time unit refers to the time unit corresponding to when the terminal device needs to send the first scheduling request and uplink information. Schematically, the target time unit is a symbol, b symbol group, c time slot or d subframe, where a, b, c and d are positive integers, which are not limited in this embodiment.

[0099] Optionally, the terminal device uses multiple uplink logical channels for data transmission, and parameters of at least two uplink logical channels among the multiple uplink logical channels are different. The "multiple" may be understood as "n", where n is a positive integer. Optionally, n≥2.

[0100] Optionally, the parameters of the uplink logical channel are used to indicate the transmission requirements of the uplink logical channel, and the parameters of the uplink logical channel include: at least one of: Transmission Time Interval (TTI), subcarrier spacing, delay and reliability. Optionally, there is at least one parameter measured by priority. Schematically, TTI is measured in milliseconds (ms) or orthogonal frequency division multiplexing (OFDM), for example: the time length of 1 TTI is 0.5ms, or 7 symbols, 4 symbols, 3 symbols or 2 OFDM symbols, etc.; the subcarrier spacing is measured in kilohertz kHz; reliability can be measured by packet loss rate. Alternatively, both delay and reliability are measured by QoS (Quality of Service) priority. This embodiment does not limit the type and measurement method of the parameters of the uplink logical channel.

[0101] Step 202: The terminal device determines the physical resources within the target time unit configured by the access network device.

[0102] Optionally, the terminal device receives configuration information sent by the access network device, and determines the physical resources within the target time unit according to the configuration information.

[0103] Step 203: When the first scheduling request and uplink information need to be sent within the target time unit, the terminal device simultaneously sends the uplink information and the second scheduling request to the access network device on the physical resources within the target time unit.

[0104] Optionally, the first scheduling request is a scheduling request that is not actually generated by the terminal device or is a scheduling request that is generated by the terminal device but not sent to the access network device. Schematically, the first scheduling request is 2-bit information, and when the value of the first scheduling request is "00", it is used to indicate that there is data to be sent in the uplink logical channel 1; when the value of the first scheduling request is "01", it is used to indicate that there is data to be sent in the logical channel 2; when the value of the first scheduling request is "10", it is used to indicate that there is data to be sent in the logical channel 3; when the value of the first scheduling request is "11", it is used to indicate that there is data to be sent in the logical channel 4.

[0105] The number of physical resources required when the first scheduling request is transmitted is greater than the number of physical resources required when the second scheduling request is transmitted.

[0106] Optionally, the second scheduling request is 1-bit information. When the value of the 1-bit information is a first preset value, it indicates that there is uplink data to be sent in multiple uplink logical channels. When the value of the 1-bit information is a second preset value, it indicates that there is no uplink data to be sent in the multiple uplink logical channels.

[0107] For example, the target time unit is a time slot. When the first scheduling request SR1 and the uplink information X1 need to be sent within the time slot, the terminal device simultaneously sends the uplink information X1 and the second scheduling request SR2 to the access network device on the physical resources within the time slot. The value of the second scheduling request SR2 is the first preset value "1", which indicates to the access network device that there is uplink data to be sent in multiple uplink logical channels of the terminal device.

[0108] Step 204: The access network device receives uplink information and a second scheduling request simultaneously sent by the terminal device on physical resources within the target time unit.

[0109] Optionally, after receiving the uplink information and the second scheduling request on the physical resources within the target time unit, the access network device determines a set of parameters based on the parameters of multiple uplink logical channels of the terminal device, and configures physical resources for transmitting uplink data to the terminal device based on the set of parameters.

[0110] In summary, in the embodiments of the present invention, when the first scheduling request and uplink information need to be sent within the target time unit, the terminal device simultaneously sends the uplink information and the second scheduling request to the access network device on the physical resources within the target time unit; the terminal device can transmit the uplink information and the second scheduling request on the dedicated physical resources used to transmit the first scheduling request or uplink information, thereby improving the utilization rate of these dedicated physical resources by the LTE system.

[0111] It should be noted that the physical resources in the target time unit configured by the access network device to the terminal device include: first-class physical resources and / or second-class physical resources. Among them, the first-class physical resources are physical resources used to transmit the first scheduling request; the second-class physical resources are physical resources used to transmit uplink information. Figure 3 The provided embodiment introduces a process in which a terminal device uses a first type of physical resource to simultaneously transmit uplink information and a second scheduling request. Figure 4 The provided embodiment introduces a process in which a terminal device uses a second type of physical resource to simultaneously transmit uplink information and a second scheduling request.

[0112] Please refer to Figure 3 , which shows a flowchart of an uplink control information transmission method provided by an exemplary embodiment of the present invention, the method is used to Figure 1 In the mobile communication system shown in FIG.

[0113] Step 301: The access network device sends first configuration information to the terminal device.

[0114] The first configuration information is used to configure the first type of physical resources for the terminal device, and the first type of physical resources are physical resources used to transmit the first scheduling request. In other words, the first type of physical resources are physical resources configured by the access network device to the terminal device for transmitting the first scheduling request, but the terminal device does not use the physical resources to transmit the first scheduling request.

[0115] Step 302: The terminal device receives first configuration information sent by the access network device.

[0116] Step 303: The terminal device uses the first type of physical resources within the target time unit to send uplink information to the access network device.

[0117] Optionally, the first type of physical resources are 2-bit physical resources, and the first uplink information transmitted using the first type of physical resources is 2-bit information.

[0118] At this time, the uplink information is sent on the first type of physical resources and is also used to implicitly indicate the second scheduling request.

[0119] Step 304: The access network device receives uplink information sent by the terminal device using the first type of physical resources within the target time unit.

[0120] Step 305: When the access network device receives uplink information on the first type of physical resources, it determines a second scheduling request corresponding to the first type of physical resources.

[0121] The second scheduling request is used to indicate that there is uplink data to be sent in the terminal device.

[0122] Optionally, when the physical resources used by the terminal device to send uplink information to the access network device are first-class physical resources, when the access network device receives uplink information on the first-class physical resources, the access network device determines that there is uplink data to be sent in the terminal device.

[0123] For example, the terminal device uses three uplink logical channels for data transmission, and the terminal device uses the first type of physical resources S to send uplink information X1 to the access network device. When the access network device receives the uplink information X1 on the first type of physical resources S, it determines that the terminal device also indicates a second scheduling request, and the second scheduling request indicates that there is data to be sent on one or several uplink logical channels on the terminal device.

[0124] Step 306: The access network device determines the parameters used for scheduling uplink data transmission according to the parameters of the multiple uplink logical channels of the terminal device.

[0125] Optionally, each uplink logical channel has its own parameters. Taking the example that each logical channel has m (m is a positive integer) parameters, the method for determining the parameters used for scheduling uplink data transmission includes but is not limited to the following two methods:

[0126] A first possible determination method is that the access network device determines, for each type of parameter, parameters that simultaneously meet the transmission requirements of multiple uplink logical channels according to the priority of the parameters corresponding to the uplink logical channels with data to be sent as parameters used for scheduling uplink data transmission.

[0127] For example, the parameters of the uplink logical channel include transmission time interval, subcarrier spacing, delay and packet loss rate. There are three uplink logical channels with data to be sent, namely channel 1, channel 2 and channel 3. The parameters of the three uplink logical channels are shown in Table 2. Among them, the parameters of channel 1 include: transmission time interval "1ms", subcarrier spacing "15kHz", delay "100ms" and packet loss rate 10%"; the parameters of channel 2 include: transmission time interval "0.5ms", subcarrier spacing "30kHz", delay "50ms" and packet loss rate "1%"; the parameters of channel 3 include: transmission time interval "0.25ms", subcarrier spacing "60kHz", delay "25ms" and packet loss rate "1%". Therefore, the access network equipment determines three parameters that meet the transmission requirements of multiple uplink logical channels at the same time: the shortest transmission time interval "0.25ms", the largest subcarrier spacing "60kHz", the shortest delay "25ms" and the highest reliability "1%", and combines these parameters into the parameters used for scheduling uplink data transmission.

[0128] Table 2

[0129]

[0130]

[0131] The second possible determination method is: the access network device determines the uplink logical channel that meets the most stringent preset conditions as the target logical channel, and determines the corresponding parameters of the target logical channel as the parameters used for scheduling uplink data transmission, wherein the preset conditions include at least one of the shortest transmission time interval, the largest subcarrier interval, the shortest delay and the highest reliability.

[0132] As shown in Table 2 above, for the parameters of the three uplink logical channels, the access network device determines channel 3 that meets the two preset conditions of "shortest delay" as the target logical channel, and determines the parameters corresponding to channel 3 (transmission time interval "0.25ms", subcarrier spacing "60kHz", delay "25ms" and packet loss rate "1%) as the parameters used for scheduling uplink data transmission. This embodiment does not limit the method for determining the parameters used for scheduling uplink data transmission.

[0133] Step 307: The access network device configures the third type of physical resources to the terminal device according to the parameters used for scheduling uplink data transmission. The third type of physical resources are physical resources used to transmit uplink data.

[0134] Optionally, the access network device configures the third type of physical resources, and / or modulation and coding level, and / or transmission power, and / or precoding information for transmitting uplink data to the terminal device according to the parameters used for scheduling uplink data transmission.

[0135] To summarize, in the embodiments of the present invention, when the first scheduling request and uplink information need to be sent within the target time unit, the terminal device simultaneously sends the uplink information and the second scheduling request to the access network device on the physical resources within the target time unit; the terminal device can schedule the request and uplink information simultaneously, thereby improving the transmission efficiency of the uplink control signaling.

[0136] It should be noted that the first type of physical resources includes multiple first physical resources, and there is a corresponding relationship between the multiple first physical resources and the multiple uplink logical channels, including the following three possible corresponding relationships:

[0137] The first possible correspondence is that there is a one-to-one correspondence between each first physical resource and the uplink logical channel. The correspondence is pre-configured and stored by the access network device, and the correspondence is shown in Table 3. Among them, the first type of physical resources includes the first physical resource S1, the first physical resource S2, the first physical resource S3 and the first physical resource S4. When the terminal uses the first physical resource S1, it is used to indicate that there is uplink data to be sent in the uplink logical channel 1; when the terminal uses the first physical resource S2, it is used to indicate that there is uplink data to be sent in the uplink logical channel 3; when the terminal uses the first physical resource S3, it is used to indicate that there is uplink data to be sent in the uplink logical channel 3; when the terminal uses the first physical resource S4, it is used to indicate that there is uplink data to be sent in the uplink logical channel 4.

[0138] Table 3

[0139] First physical resource Uplink logical channel First physical resource S1 Uplink logical channel 1 First physical resource S2 Uplink logical channel 2 First physical resource S3 Uplink logical channel 3 First physical resource S4 Uplink logical channel 4

[0140] The second possible correspondence is that each uplink logical channel corresponds to multiple first physical resources. The correspondence is pre-configured and stored by the access network device, and the correspondence is shown in Table 4. Among them, the first type of physical resources includes the first physical resource S1, the first physical resource S2 and the first physical resource S3. When the terminal uses the first physical resource S1, it is used to indicate that there is uplink data to be sent in the uplink logical channel 1. When the terminal uses the first physical resource S2, it is used to indicate that there is uplink data to be sent in the uplink logical channel 2. When the terminal uses the first physical resource S3, it is used to indicate that there is uplink data to be sent in the uplink logical channel 1 and the uplink logical channel 2.

[0141] Table 4

[0142] Uplink logical channel First physical resource Uplink logical channel 1 First physical resource S1 Uplink logical channel 2 First physical resource S2 Uplink logical channels 1 and 2 First physical resource S3

[0143] The third possible correspondence is that each first physical resource corresponds to multiple uplink logical channels. This correspondence is pre-configured and stored by the access network device, and the correspondence is shown in Table 5. Among them, the first type of physical resources includes the first physical resource S1 and the first physical resource S2. When the terminal uses the first physical resource S1, it is used to indicate that there is uplink data to be sent in the uplink logical channel 1 and / or the uplink logical channel 2. When the terminal uses the first physical resource S2, it is used to indicate that there is uplink data to be sent in the uplink logical channel 3 and / or the uplink logical channel 4. For example, the first physical resource S1 is 1-bit information. When the value is 0, it indicates that there is data to be sent in the uplink logical channel 1; when the value is 1, it indicates that there is data to be sent in the uplink logical channel 2.

[0144] Table 5

[0145]

[0146] The correspondence between the above-mentioned multiple first physical resources and multiple uplink logical channels is only illustrative. On the basis of the above-mentioned various possible implementation methods, the solutions that can be obtained by those skilled in the art in combination with conventional technical means are all within the scope of protection required by this application.

[0147] Optionally, based on the third possible corresponding relationship provided in Table 5, there is a fourth possible corresponding relationship, which is shown in Table 6. For example, the first physical resource S3 is 1-bit information, and when the value is 0, it indicates that there is data to be sent in the uplink logical channel 1 and the uplink logical channel 2; when the value is 1, it indicates that there is data to be sent in the uplink logical channel 1 and the uplink logical channel 3.

[0148] Table 6

[0149]

[0150]

[0151] Please refer to Figure 4 , which shows a flowchart of an uplink control information transmission method provided by another exemplary embodiment of the present invention, the method is used to Figure 1 In the mobile communication system shown in FIG.

[0152] Step 401: The access network device sends first configuration information to the terminal device.

[0153] The first configuration information is used to configure the first type of physical resources for the terminal device, and the first type of physical resources includes multiple first physical resources, and there is a corresponding relationship between the multiple first physical resources and the multiple uplink logical channels.

[0154] Step 402: The terminal device receives first configuration information sent by the access network device.

[0155] Step 403: The terminal device uses at least one first physical resource within the target time unit to send uplink information to the access network device.

[0156] Optionally, the first type of physical resources includes multiple first physical resources, each first physical resource is a 2-bit physical resource, and the uplink information transmitted using the first physical resource is 2-bit information.

[0157] The terminal device uses at least one first physical resource within the target time unit to send uplink information to the access network device, including but not limited to the following two possible implementations:

[0158] In a first possible implementation manner, the terminal device uses a first physical resource within a target time unit to send uplink information to the access network device.

[0159] For example, the first type of physical resources includes the first physical resource S1 and the first physical resource S2, and the access network device pre-configures: the first physical resource S1 corresponds to the uplink logical channel 1 and the uplink logical channel 2, and the first physical resource S2 corresponds to the uplink logical channel 3 and the uplink logical channel 4. The terminal device uses the first physical resource S1 within the target time unit to send the uplink information X1 to the access network device.

[0160] In a second possible implementation manner, the terminal device uses at least two first physical resources within the target time unit to send uplink information to the access network device, and each first physical resource transmits the same uplink information.

[0161] For example, the first type of physical resources includes the first physical resource S1 and the first physical resource S2, and the access network device pre-configures: the first physical resource S1 corresponds to the uplink logical channel 1 and the uplink logical channel 2, and the first physical resource S2 corresponds to the uplink logical channel 3 and the uplink logical channel 4. When the terminal device uses the first physical resource S1 within the target time unit to send the uplink information X1 to the access network device, it also uses the first physical resource S2 within the target time unit to send the uplink information X1 to the access network device.

[0162] Optionally, at least one first physical resource used by the terminal to transmit uplink information includes: a physical resource corresponding to a first logical channel, the first logical channel being an uplink logical channel determined by the terminal device according to the priority of parameters corresponding to the uplink logical channel in which data to be sent exists. Schematically, the priority of the parameters corresponding to the uplink logical channel is agreed upon by the protocol.

[0163] Optionally, the terminal device determines that the first logical channel is the uplink logical channel with the highest transmission requirement based on the priority of the corresponding parameters of the uplink logical channel where data to be sent exists, and the first logical channel satisfies at least one of the following parameter conditions: minimum transmission time interval, minimum subcarrier spacing, shortest delay and highest reliability.

[0164] For example, there are uplink logical channels for data to be sent, namely uplink logical channel 1 and uplink logical channel 2, uplink logical channel 1 corresponds to physical resource S1, and uplink logical channel 1 corresponds to physical resource S2. If uplink logical channel 1 satisfies the above-mentioned parameter conditions, that is, uplink logical channel 1 is the first logical channel, then the at least one first physical resource S used by the terminal device to send uplink information to the access network device includes the physical resource S1 corresponding to logical channel 1.

[0165] Step 404: The access network device receives uplink information sent by the terminal device using at least one first physical resource within the target time unit.

[0166] Step 405: When the access network device receives uplink information on at least one first physical resource, it determines a second scheduling request corresponding to the at least one first physical resource.

[0167] The second scheduling request is used to indicate that there is uplink data to be sent on the uplink logical channel corresponding to the at least one first physical resource.

[0168] Optionally, the terminal device sends uplink information to the access network device using the first possible implementation method in step 403. Correspondingly, when the access network device receives the uplink information on the first physical resource, it determines that there is uplink data to be sent on the uplink logical channel corresponding to the first physical resource.

[0169] For example, when the access network device receives uplink information X1 on the first physical resource S1, it determines that there is uplink data to be sent on the uplink logical channel 1 and / or uplink logical channel 2 corresponding to the first physical resource S1. Optionally, the terminal device sends uplink information to the access network device using the second possible implementation method in step 403, and correspondingly, when the access network device receives uplink information on at least two first physical resources, it determines that there is uplink data to be sent on the uplink logical channels corresponding to at least two first physical resources.

[0170] For example, when the access network device receives uplink information X1 on the first physical resource S1, it determines that there is uplink data to be sent on the uplink logical channel 1 and / or the uplink logical channel 2 corresponding to the first physical resource S1; and / or, when the access network device receives uplink information X1 on the first physical resource S2, it determines that there is uplink data to be sent on the uplink logical channel 1 and / or the uplink logical channel 2 corresponding to the first physical resource S2.

[0171] Step 406: The access network device determines parameters used for scheduling uplink data transmission according to parameters of an uplink logical channel corresponding to the at least one first physical resource.

[0172] Optionally, each uplink logical channel corresponds to its own parameters. Taking the example that each logical channel corresponds to m (m is a positive integer) parameters, the method for determining the parameters used for scheduling uplink data transmission includes but is not limited to the following possible implementation methods.

[0173] In a possible implementation, based on the correspondence shown in Table 3, that is, each first physical resource corresponds to an uplink logical channel one-to-one. If the terminal device uses a first physical resource to send uplink data to the access network device, the access network device determines the parameters of the uplink logical channel corresponding to the first physical resource as the parameters used for scheduling uplink data transmission.

[0174] For example, the terminal device uses a first physical resource S1 to send uplink data to the access network device. The access network device determines the parameters of the uplink logical channel 1 corresponding to the first physical resource S1 (transmission time interval "0.25ms", subcarrier spacing "60kHz", delay "25ms" and packet loss rate "1%) as the parameters used for scheduling uplink data transmission.

[0175] In another possible implementation, based on the correspondence shown in Table 3, each first physical resource corresponds to an uplink logical channel one-to-one. If the terminal device uses at least two first physical resources to send uplink data to the access network device, the access network device determines the parameters used for scheduling uplink data transmission according to the parameters of the uplink logical channels corresponding to the at least two first physical resources. Figure 3 The method for determining the parameters used for scheduling uplink data transmission in the provided embodiment will not be described in detail here.

[0176] In another possible implementation, based on the correspondence shown in Table 4, that is, each uplink logical channel has a correspondence with multiple first physical resources. If the terminal device uses a first physical resource to send uplink data to the access network device, the access network device determines the parameters of the uplink logical channel corresponding to the first physical resource as the parameters used for scheduling uplink data transmission.

[0177] For example, the terminal device uses a first physical resource S2 to send uplink data to the access network device. The access network device determines the parameters of the uplink logical channel 2 corresponding to the first physical resource S2 (transmission time interval "0.5ms", subcarrier spacing "30kHz", delay "50ms" and packet loss rate "1%) as the parameters used for scheduling uplink data transmission.

[0178] In another possible implementation, based on the correspondence shown in Table 4, each uplink logical channel corresponds to multiple first physical resources. If the terminal device uses at least two first physical resources to send uplink data to the access network device, the access network device determines the parameters used for scheduling uplink data transmission according to the parameters of the uplink logical channels corresponding to the at least two first physical resources. Figure 3 The method for determining the parameters used for scheduling uplink data transmission in the provided embodiment will not be described in detail here.

[0179] In another possible implementation, based on the correspondence shown in Table 5, that is, each first physical resource has a correspondence with multiple uplink logical channels. If the terminal device uses at least one first physical resource to send uplink data to the access network device, the access network device determines the parameters used for scheduling uplink data transmission according to the parameters of the uplink logical channel corresponding to the at least one first physical resource. Figure 3 The method for determining the parameters used for scheduling uplink data transmission in the provided embodiment will not be described in detail here.

[0180] Step 407: The access network device configures the third type of physical resources to the terminal device according to the parameters used for scheduling uplink data transmission. The third type of physical resources are physical resources used to transmit uplink data.

[0181] Optionally, the access network device configures a third type of physical resource for transmitting uplink data to the terminal device according to the parameters used for scheduling uplink data transmission, where the third type of physical resource is an i-bit physical resource, where i is a positive integer greater than 1.

[0182] In summary, in the embodiments of the present invention, when the first scheduling request and uplink information need to be sent within the target time unit, the terminal device simultaneously sends the uplink information and the second scheduling request to the access network device on the physical resources within the target time unit; the terminal device can transmit the uplink information and the second scheduling request on the dedicated physical resources used to transmit the first scheduling request or uplink information, thereby improving the utilization rate of these dedicated physical resources by the LTE system.

[0183] The embodiment of the present invention also configures the first type of physical resources for transmitting the first scheduling request to the terminal device through the access network device, and the terminal device uses the first type of physical resources within the target time unit to send uplink information to the access network device, so that the terminal device can transmit uplink information on the dedicated physical resources used to transmit the first scheduling request, thereby improving the utilization rate of these dedicated physical resources by the LTE system.

[0184] The embodiment of the present invention also establishes a correspondence between multiple first physical resources and the multiple uplink logical channels. When the access network device receives uplink information on the first type of physical resources, it can determine the second scheduling request, and then determine that there is uplink data to be sent in the terminal device indicated by the second scheduling request, so that the first physical resource can implicitly indicate the second scheduling request.

[0185] Please refer to Figure 5 , which shows a flowchart of an uplink control information transmission method provided by an exemplary embodiment of the present invention, the method is used to Figure 1 In the mobile communication system shown in FIG.

[0186] Step 501: The access network device sends second configuration information to the terminal device.

[0187] The second configuration information is used to configure the second type of physical resources for the terminal device, and the second type of physical resources are physical resources used to transmit uplink information.

[0188] Step 502: The terminal device receives second configuration information sent by the access network device.

[0189] Step 503: The terminal device uses the second type of physical resources within the target time unit to send uplink information and a second scheduling request to the access network device.

[0190] The second type of physical resources are physical resources configured by the access network device to the terminal device for transmitting uplink information. Optionally, the second type of physical resources are P-bit physical resources, the uplink information transmitted using the second type of physical resources is P-1-bit information, the second scheduling request transmitted using the second type of physical resources is 1-bit information, and P is a positive integer greater than 1.

[0191] Optionally, the second scheduling request is 1-bit information. When the value of the 1-bit information is a first preset value (such as "1"), it indicates that there is uplink data to be sent in multiple uplink logical channels. When the value of the 1-bit information is a second preset value (such as "0"), it indicates that there is no uplink data to be sent in the multiple uplink logical channels.

[0192] Schematically, when the terminal device determines a 1-bit second scheduling request, it concatenates the 1-bit second scheduling request with P-1 bits of uplink information and performs joint encoding. After encoding, the terminal device uses the second type of physical resources within the target time unit to send the uplink information and the second scheduling request to the access network device.

[0193] For example, the second scheduling request is 1-bit information "1" and the uplink information is 4-bit information "1010", then the terminal device uses the second type of physical resources T to send 5-bit information "10101" to the access network device.

[0194] Step 504: The access network device receives uplink information and a second scheduling request sent by the terminal device using the second type of physical resources within the target time unit.

[0195] Optionally, after receiving the 5-bit information "10101" sent by the terminal device using the second type of physical resources within the target time unit, the access network device determines the uplink information "1010" and the second scheduling request "1", where the second scheduling request "1" is used to indicate to the access network device that there is uplink data to be sent in multiple uplink logical channels of the terminal device.

[0196] Step 505: The access network device determines the parameters used for scheduling uplink data transmission according to the parameters of multiple uplink logical channels of the terminal device.

[0197] Optionally, each uplink logical channel has its own parameters. Taking m (m is a positive integer) parameters corresponding to each logical channel as an example, the method for determining the parameters used for scheduling uplink data transmission includes but is not limited to two possible determination methods. For details, refer to Figure 3 The method for determining the parameters used for scheduling uplink data transmission in the illustrated embodiment will not be described in detail here.

[0198] Step 506: The access network device configures the third type of physical resources to the terminal device according to the parameters used for scheduling uplink data transmission. The third type of physical resources are physical resources used to transmit uplink data.

[0199] Optionally, the access network device configures a third type of physical resource for transmitting uplink data to the terminal device according to the parameters used for scheduling uplink data transmission, where the third type of physical resource is an i-bit physical resource, where i is a positive integer greater than 1.

[0200] In summary, in the embodiments of the present invention, when the first scheduling request and uplink information need to be sent within the target time unit, the terminal device simultaneously sends the uplink information and the second scheduling request to the access network device on the physical resources within the target time unit; the terminal device can transmit the uplink information and the second scheduling request on the dedicated physical resources used to transmit the first scheduling request or uplink information, thereby improving the utilization rate of these dedicated physical resources by the LTE system.

[0201] The embodiment of the present invention also configures the second type of physical resources for transmitting uplink information to the terminal device through the access network device, and the terminal device uses the second type of physical resources within the target time unit to send the uplink information and the second scheduling request to the access network device, so that the terminal device can transmit the uplink information and the second scheduling request on the dedicated physical resources for transmitting the uplink information, thereby improving the utilization rate of these dedicated physical resources by the LTE system.
