Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a communication processing method and a terminal. Background Art

[0002] Currently, in order to ensure the efficiency of data transmission between the UE and the base station, the UE and the base station may interact with each other so that the base station may configure radio resources for data transmission for the UE.

[0003] In some implementations, the base station does not allocate wireless resources for data transmission to the UE, or allocates fewer wireless resources to the UE, resulting in low efficiency of data transmission between the UE and the base station, causing communication jams in the UE. Summary of the invention

[0004] The embodiments of the present application provide a communication processing method and a terminal, so that a base station can configure wireless resources for data transmission for a UE, thereby ensuring the efficiency of data transmission between the UE and the base station and improving the user's communication experience.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a communication processing method is applied to a terminal. A first radio resource control (RRC) connection is established between the terminal and a first access network device. The method includes: sending first UE auxiliary information. The first UE auxiliary information is used to request a first physical resource from the first access network device. The first physical resource is used to transmit at least one of a scheduling request SR, a channel state information CS I report, and a sounding reference signal SRS. A first RRC connection reconfiguration message is received. The first RRC connection reconfiguration message includes first information. The first information is used to indicate information about the first physical resource.

[0007] Based on the above solution, the UE can obtain the first physical resource by sending the first UE auxiliary information to the first access network device. In this way, the UE can subsequently realize at least one of transmitting a wireless resource for data transmission based on the first physical resource transmission SR request, transmitting a CSI report based on the first physical resource to feedback the current channel quality, and sending an SRS to the first access network device for channel quality measurement. This provides a guarantee for the subsequent UE to obtain more wireless resources for data transmission.

[0008] Optionally, the first physical resource is used to transmit the SR. After receiving the first RRC connection reconfiguration message, the method also includes: sending the SR. The SR is used to request resources for uplink data transmission from the first access network device. Obtain a first wireless resource. The first wireless resource is allocated to the terminal when the first access network device receives the SR. Based on the first wireless resource, the first uplink data is sent. Thus, the UE can obtain wireless resources for data transmission by sending an SR to the first access network device. The efficiency of the UE in data transmission is guaranteed, and the problem of communication jamming of the UE is avoided.

[0009] Optionally, the first physical resource is used to transmit the CSI report. After receiving the first RRC connection reconfiguration message, the method further includes: sending the first CSI report. The first CSI report includes a first channel quality indication CQI. The first CQI is used to indicate the current first channel quality. The first CQI is obtained by measuring a first CSI reference signal. The first CSI reference signal is sent by the first access network device. Based on the second wireless resource, the first downlink data is received. The second wireless resource is allocated to the terminal by the first access network device according to the first CQI.

[0010] Based on the above solution, the UE can send a CSI report to the first access network device to feedback the current channel quality. After receiving the CSI report, the first access network device can allocate wireless resources for transmitting downlink data to the UE according to the current channel quality. This can ensure the performance of the UE in downlink data transmission, improve the efficiency of UE data transmission, and improve the user's communication experience.

[0011] Optionally, the first physical resource is used to transmit the SRS. After receiving the first RRC connection reconfiguration message, the method further includes: sending the SRS. Sending second uplink data based on a third wireless resource. The third wireless resource is allocated to the terminal by the first access network device according to a second channel quality. The second channel quality is obtained by the first access network device by measuring the SRS.

[0012] Based on the above scheme, the UE can send an SRS to the first access network device, so that the first access network device can obtain the current second channel quality by measuring the SRS. The first access network device can allocate a third wireless resource for transmitting uplink data to the terminal according to the second channel quality, so that the UE can transmit the second uplink data on the third wireless resource. The performance and rate of the terminal in uplink data transmission are guaranteed.

[0013] Optionally, before sending the first UE auxiliary information, the method further includes: sending the SR N times.

[0014] When N exceeds a preset number of times, the second physical resource configured for transmitting the SR is released, a first random access process is initiated to the first access network device to obtain a fourth wireless resource, and third uplink data is sent based on the fourth wireless resource.

[0015] Optionally, the terminal is configured with a first counter. The first counter is configured to increase by 1 each time the first random access process is initiated to the first access network device. The method also includes: starting the first counter when the first random access process is initiated to the first access network device for the first time. Thus, the terminal can obtain the number of times the terminal initiates the random access process to the first access network device through the first counter. So that the subsequent terminal can perform subsequent processing according to the number.

[0016] Optionally, after initiating the first random access process to the first access network device, the method further includes: determining whether the value of the first counter exceeds the first preset threshold. The sending of the first UE auxiliary information includes: sending the first UE auxiliary information when it is determined that the value of the first counter exceeds the first preset threshold. Thus, when the number of times the terminal initiates a random access process to the first access network device exceeds a preset number, the first UE auxiliary information is initiated to request the first physical resource for transmitting the SR. The terminal can subsequently request wireless resources for data transmission by sending an SR, thereby avoiding the terminal obtaining wireless resources for data transmission by initiating a random access process multiple times, and further enabling the terminal to obtain more wireless resources for transmission, thereby improving the efficiency of data transmission.

[0017] Optionally, the terminal is configured with a first timer. The timing duration of the first timer is a first duration. When the first random access process is initiated to the first access network device for the first time, the method further includes: starting the first timer. The sending of the first UE auxiliary information includes: sending the first UE auxiliary information when the first timer expires.

[0018] Thus, after the terminal initiates the first duration of the random access process to the first access network device, it can initiate the first UE auxiliary information request to transmit the first physical resource of the SR. The terminal can subsequently request the wireless resource for data transmission by sending the SR, avoiding the terminal from obtaining the wireless resource for data transmission by initiating the random access process multiple times, and then the terminal can obtain more wireless resources for transmission, thereby improving the efficiency of data transmission.

[0019] Optionally, before sending the first UE auxiliary information, the method further includes: receiving a second RRC connection reconfiguration message. The sending of the first UE auxiliary information includes: when the second RRC connection reconfiguration message does not include the first information, sending the first UE auxiliary information. Thus, when the first physical resource for transmitting the CSI report or transmitting the SRS is not configured in the terminal, the terminal can request the first physical resource for transmitting the CSI report or transmitting the SRS by sending the first UE auxiliary information.

[0020] Optionally, the terminal is configured with a second timer. The timing duration of the second timer is a second duration. Before sending the first UE auxiliary information, the method also includes: when the second RRC connection reconfiguration message does not include the first information, starting the second timer. Sending the first UE auxiliary information includes: sending the first UE auxiliary information when the second timer expires. Thus, the terminal can start the second timer when it is determined that the first physical resource for transmitting the CSI report or transmitting the SRS is not configured in the terminal. When the second timer expires, the first UE auxiliary information is sent to the first access network device to request the first physical resource.

[0021] In a second aspect, a terminal includes: a memory and one or more processors. The memory is coupled to the processor. The memory is used to store computer program code, and the computer program code includes computer instructions. When the processor executes the computer instructions, the terminal executes the communication processing method provided in the first aspect and any possible design thereof.

[0022] In a third aspect, a chip system includes a processor and a communication interface. The processor is used to call and run a computer program stored in a storage medium from a storage medium to execute a communication processing method provided in the first aspect and any possible design thereof.

[0023] In a fourth aspect, a computer-readable storage medium stores computer instructions thereon, which, when executed by a processor, implement the communication processing method provided in the first aspect and any possible design thereof.

[0024] In a fifth aspect, a computer program product comprises computer instructions, which, when executed by a processor, implement the communication processing method provided in the first aspect and any possible design thereof.

[0025] It can be understood that the technical solutions provided in the second to fifth aspects above can respectively correspond to the communication processing methods provided in the aforementioned designs, and the beneficial effects that can be obtained are similar and will not be repeated here.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0038] The technical solution provided in the embodiments of the present application can be applied to various wireless communication networks, such as: global system for mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, universal mobile telecommunication system (UMTS) system, general packet radio service (GPRS) system, long term evolution (LTE) system, long term evolution advanced (LTE-A) system, world-wide interoperability for microwave access (WiMAX) system, new radio network of fifth generation mobile communication technology (5G), network of sixth generation mobile communication technology (6G), etc. The terms "network" and "system" can be used interchangeably.

[0039] In the embodiment of the present application, a base station (BS) may be a device that communicates with a user equipment (UE) or other communication sites such as a relay site, and the base station may provide communication coverage for a specific physical area. For example, the base station may be a base transceiver station (BTS) or a base station controller (BSC) in GSM or CDMA; it may also be a node B (NB) in UMTS or a radio network controller (RNC) in UMTS; it may also be an evolutionary Node B (eNB or eNodeB) in LTE; it may also be a next generation Node B (gNB) in 5G NR; or it may be other access network devices that provide access services in a wireless communication network, which is not limited by the present invention.

[0040] Currently, a base station can allocate radio resources for data transmission to a UE to ensure the efficiency of data transmission by the UE.

[0041] Exemplary, reference Figure 1 , Figure 1 The diagram shows an interaction diagram of a UE requesting a base station (such as base station A) for uplink radio resources for data transmission.

[0042] like Figure 1 As shown, the interaction process may include:

[0043] S101. UE establishes an RRC connection with base station A.

[0044] Exemplarily, the UE sends an RRC connection establishment request to base station A. The RRC connection establishment request may be RRCConnectionRequest.

[0045] Correspondingly, after receiving the RRC connection establishment request, base station A sends an RRC connection establishment message (such as RRCConnectionsetup) to the UE.

[0046] Then, the UE may perform RRC connection establishment according to the RRC connection establishment message. In this example, after completing the RRC connection establishment, the UE feeds back an RRC connection establishment completion message to the base station A. For example, the RRC connection establishment completion message may be RRCConnectionComplete.

[0047] As a result, an RRC connection is established between UE and base station A.

[0048] In other embodiments of the present application, the RRC connection may also be referred to as a first RRC connection.

[0049] S102. UE sends SR to base station A.

[0050] In the embodiment of the present application, when the UE needs to transmit data, it can send an SR to the base station A based on the RRC connection in S101. The SR is used to request the base station A for radio resources for transmitting data.

[0051] It can be understood that before the UE sends the SR to the base station A, the UE is correspondingly configured with a first SR resource. The first SR resource is used to transmit the SR. The first SR resource is configured by the base station A to the UE.

[0052] In some other embodiments of the present application, the first SR resource may also be referred to as a second physical resource.

[0053] S103. Base station A sends an uplink scheduling grant A to the UE.

[0054] Exemplarily, when receiving the SR, base station A allocates wireless resource 1 for transmitting data to the UE in response to the SR, and sends an uplink scheduling authorization A to the UE. The uplink scheduling authorization A may include allocation information of wireless resource 1. The uplink scheduling authorization A is used to indicate that the UE can transmit data on wireless resource 1.

[0055] For example, the wireless resource 1 may be a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resource. The uplink scheduling grant A may be a UL GRANT.

[0056] Correspondingly, after receiving the uplink scheduling grant A, the UE can transmit data on the designated wireless resource 1 according to the uplink scheduling grant A.

[0057] For example, the UE may transmit uplink data 1 to the base station A on the radio resource 1.

[0058] In some other embodiments of the present application, the wireless resource 1 may also be referred to as a first wireless resource. The uplink data 1 may also be referred to as first uplink data.

[0059] S104. UE sends a buffer status report to base station A.

[0060] Optionally, after receiving the uplink scheduling grant A, the UE may send a buffer status report to the base station A on the designated radio resource 1 based on the uplink scheduling grant A. The buffer status report is used to indicate the amount of data that the UE needs to transmit.

[0061] Correspondingly, after receiving the buffer status report, base station A can perform the processing in S105 and S106.

[0062] S105. Base station A sends an uplink scheduling grant B to the UE.

[0063] Exemplarily, base station A may configure radio resource 2 for the UE according to the amount of data that the UE needs to transmit as indicated in the buffer status report, and send an uplink scheduling grant B to the UE. The uplink scheduling grant B may include allocation information of radio resource 2. The uplink scheduling grant B is used to indicate that the UE can transmit data on radio resource 2.

[0064] Correspondingly, after receiving the uplink scheduling grant B, the UE can transmit data on the designated wireless resource 2 according to the uplink scheduling grant B.

[0065] S106. UE sends uplink data 1 to base station A.

[0066] For example, after receiving the uplink scheduling grant B, the UE may send uplink data 1 on the designated wireless resource 2.

[0067] exist Figure 1 In the example of FIG. 1 , the UE sends an SR to the base station A to obtain the wireless resources for transmitting data. In other embodiments, reference is made to FIG. Figure 2 , Figure 2 Another interactive schematic diagram is shown in which a UE requests an uplink radio resource from a base station (such as base station A) for data transmission.

[0068] like Figure 2 As shown, the interaction process may include:

[0069] S201. UE establishes an RRC connection with base station A.

[0070] In this example, S201 is implemented in the same manner as S101. For details, please refer to the description in S101 and will not be repeated here.

[0071] S202. UE sends SR to base station A.

[0072] Exemplarily, when the UE needs to transmit data, it can send an SR to base station A to request wireless resources for data transmission based on the configured first SR resources.

[0073] In some cases (such as network congestion), the UE cannot get a timely response from base station A. Then the UE can send SR to base station A multiple times to request wireless resources.

[0074] In the existing protocol, the base station can configure the maximum number of SR transmissions (such as sr-TransMax) to the UE. Each time the UE transmits an SR, the corresponding SR_COUNTER increases by 1. Before the next SR transmission, the UE can determine whether the SR_COUNTER is less than sr-TransMax.

[0075] Specifically, when SR_COUNTER is less than sr-TransMax and the UE has not received a response from the base station to the SR, "instruct the physical layer to signal the SR on one valid PUCCHresource for SR" is executed, that is, instructing the physical layer to send SR on a valid uplink control channel (Physical UplinkControl Channel, PUCCH) resource. Correspondingly, when SR_COUNTER is greater than or equal to sr-TransMax, the UE can release all SR resources. The execution of releasing all SR resources can be issued by the bottom layer of the UE (such as the MAC layer) to the upper layer (such as the RRC layer).

[0076] The following takes SR_COUNTER being greater than or equal to sr-TransMax as an example, and continues to explain the example.

[0077] S203. When the UE determines that the number of SR transmissions reaches a maximum number, the UE releases the first SR resource.

[0078] In combination with the above description, the UE may release the first SR resource when determining that SR_COUNTER is greater than or equal to sr-TransMax. The UE releasing the first SR resource may include releasing PUCCH resources.

[0079] In this example, when the UE needs to send data again, since the UE is not configured with SR resources, the UE cannot request wireless resources for data transmission by sending SR. At this time, the UE can obtain wireless resources for data transmission by initiating a random access process to base station A.

[0080] S204. UE initiates random access process 1 to base station A.

[0081] Exemplarily, when the UE needs to send data and the UE is not configured with available SR resources, the UE may initiate a random access process 1 to the base station A so as to obtain wireless resources for data transmission.

[0082] For example, the UE may send a random access request 1 to the base station A through a random access channel (RACH).

[0083] Correspondingly, when receiving the random access request 1, the base station A returns a random access response 1 to the UE. The random access response 1 carries an uplink scheduling grant C. The uplink scheduling grant C carries information of the radio resource_1. The uplink scheduling grant C is used to indicate that the UE can perform data transmission.

[0084] In some other embodiments of the present application, the random access procedure 1 may also be referred to as a first random access procedure. The wireless resource_1 may also be referred to as a fourth wireless resource.

[0085] S205. UE sends uplink data 2 to base station A.

[0086] Exemplarily, when the UE receives the uplink scheduling grant C carried in the random access response 1, the UE can send uplink data 2 to the base station A based on the radio resource_1 in the uplink scheduling grant C.

[0087] In some other embodiments of the present application, the uplink data 2 may also be referred to as third uplink data.

[0088] It should be noted that, in the embodiment of the present application, compared with the wireless resource 2 corresponding to the uplink scheduling grant B, the wireless resource _1 corresponding to the uplink scheduling grant C is less, and the corresponding data transmitted by the UE using the wireless resource is also less.

[0089] In other embodiments of the present application, when the UE needs to send data subsequently, it may continue to initiate multiple random access processes to the base station A so as to obtain wireless resources for data transmission.

[0090] In such Figure 2 In the example, when the UE fails to obtain wireless resources by sending SR, it releases the SR resources and obtains wireless resources for data transmission by initiating a random access process to base station A. Since the UE obtains fewer wireless resources through the random access process, the UE's data transmission rate is low, resulting in communication jams in the UE.

[0091] In other embodiments, the UE is configured with available CSI report resources. The CSI report resources are used to send CSI reports. The CSI report includes the current channel quality. In this embodiment, the UE can send a CSI report to the base station A based on the CSI report resources to feedback the current channel quality, so that the base station A can schedule and allocate wireless resources in the downlink according to the current channel quality to ensure the performance of data transmission in the downlink.

[0092] Exemplary, reference Figure 3 , Figure 3 The figure shows an interactive process of data transmission between UE and base station A in downlink.

[0093] like Figure 3 As shown, the interaction process may include:

[0094] S301. UE establishes an RRC connection with base station A.

[0095] In this example, S301 is implemented in the same manner as S101. For details, please refer to the description in S101 and will not be repeated here.

[0096] S302. Base station A sends CSI report resource configuration to UE.

[0097] Exemplarily, when a UE accesses base station A, base station A configures CSI report resources for the UE and sends the CSI report resource configuration to the UE. This facilitates the subsequent UE to report a CSI report to base station A according to the CSI report resource configuration. The CSI report resource configuration may include a period for reporting a CSI report, a time slot position, and a PUCCH or PUSCH resource configuration.

[0098] For example, base station A may carry the CSI report resource configuration in an RRC connection reconfiguration message 31 and send the RRC connection reconfiguration message 31 to the UE.

[0099] Among them, the RRC connection reconfiguration message 31 can be RRCConnectionReconfiguration.

[0100] In some other embodiments of the present application, the CSI report resource configuration is included in the first information. The RRC connection reconfiguration message 31 may also be referred to as a first RRC connection reconfiguration message.

[0101] S303. Base station A sends CSI reference signal A to UE.

[0102] In some other embodiments of the present application, the CSI reference signal A may also be referred to as a first CSI reference signal.

[0103] S304. The UE measures the CSI reference signal A to determine the current channel quality 1.

[0104] Exemplarily, after receiving the CSI reference signal A in S202, the UE may measure the CSI reference signal A and calculate a channel quality indication (CQI)_1 in the current downlink.

[0105] Wherein, CQI_1 is used to indicate the current channel quality 1. Take CQI_1 including the first value as an example. Generally, the larger the first value is, the better the corresponding current channel quality 1 is. On the contrary, the smaller the first value is, the worse the corresponding channel quality 1 is.

[0106] In some other embodiments of the present application, channel quality 1 may also be referred to as the first channel quality. CQI_1 may also be referred to as the first CQI.

[0107] S305. UE sends a CSI report to base station A.

[0108] Exemplarily, after determining CQI_1, the UE may send a CSI report to base station A. The CSI report carries CQI_1.

[0109] In this example, the UE may send a CSI report to base station A according to the CSI report resource configuration in S302, so that base station A may receive the CSI report later.

[0110] It is understandable that, in some embodiments, base station A may periodically send CSI reference signal A to UE, so that UE performs processing as in S304 and S305 upon receiving CSI reference signal A, and periodically feeds back real-time channel quality in the downlink to base station A.

[0111] S306. Base station A adjusts scheduling and allocation of downlink radio resources for the UE according to the CSI report.

[0112] Exemplarily, after receiving the CSI report, base station A may adjust the scheduling and allocation of radio resources in the downlink according to CQI_1 in the CSI report to ensure the communication performance of the downlink.

[0113] For example, taking CQI_1 including the first value as an example, when the first value is small, the channel quality corresponding to the current downlink is poor. In this implementation, when base station A receives CQI_1 carried in the CSI report, it will reduce the allocation of wireless resources in the downlink, and at the same time reduce the order of the modulation method and the order of the modulation coding scheme (MCS) in the downlink. On the contrary, when the first value is large, the quality corresponding to the current downlink is good. In this implementation, when base station A receives CQI_1 carried in the CSI report, it will increase the allocation of wireless resources in the downlink, and at the same time increase the order of the modulation method and the order of the MCS in the downlink.

[0114] S307. Base station A sends downlink data to UE.

[0115] Exemplarily, after completing the processing in S306, base station A may send downlink data to the UE based on the wireless resource 3 for transmitting downlink data currently allocated to the UE, and the adjusted modulation mode and MCS order.

[0116] In some other embodiments of the present application, the downlink data may also be referred to as first downlink data. The wireless resource 3 may also be referred to as a second wireless resource.

[0117] In such Figure 3 In the example, base station A sends CSI report resource configuration to UE as an example. In other embodiments, base station A does not send CSI report resource configuration to UE. That is, base station A does not configure CSI report resource for UE.

[0118] In this embodiment, the UE and the base station A may perform the processing in S303 and S304.

[0119] For example, base station A may send a CSI reference signal B to the UE. When the UE receives the CSI reference signal B, it may measure the CSI reference signal B to determine CQI_2. The CQI_2 is used to indicate the current channel quality.

[0120] It should be noted that the specific implementation of this embodiment can refer to Figure 3 The relevant instructions in will not be repeated here.

[0121] Since the UE is not configured with CSI reporting resources, the UE will not be able to send a CSI report to the base station A. In other words, the UE will not be able to send CQ1_2 to the base station A by reporting a CSI report.

[0122] In this embodiment, since base station A does not receive the CSI report shown in S305, base station A cannot obtain the current channel quality. At this time, base station A will reduce the allocation of wireless resources in the downlink, and reduce the order of the modulation method and the order of MCS in the downlink. As a result, the data transmission rate in the downlink is low, causing the UE to experience communication jams.

[0123] For example, referring to Table 1, Table 1 shows the time A when the UE does not feed back the CSI report to the base station A when receiving the CSI reference signal A as in S303, and the time B when the UE experiences communication jam. As shown in Table 1, time A includes T1 time, T2 time and T4 time, and time B includes T3 time and T5 time. Among them, T2 time is the same as T3 time, and T4 time is the same as T5 time.

[0124] That is to say, when the UE does not report the CSI report to base station A, base station A will reduce the allocation of wireless resources in the downlink, and at the same time reduce the modulation order and MCS order in the downlink, resulting in a low data transmission rate in the downlink, which in turn causes communication jams in the UE.

[0125] Table 1

[0126]

[0127] In some other embodiments, the UE is configured with available SRS resources, which are used to send SRS, so that the base station A can determine the current channel quality based on the SRS, and then schedule and allocate corresponding wireless resources to ensure the efficiency of data transmission of the UE.

[0128] Exemplary, reference Figure 4 , Figure 4 The diagram shows an interactive process of data transmission between a UE and a base station A in an uplink.

[0129] like Figure 4 As shown, the interaction process may include:

[0130] S401. UE establishes an RRC connection with base station A.

[0131] In this example, S401 is implemented in the same manner as S101. For details, please refer to the description in S101 and will not be repeated here.

[0132] S402. Base station A sends SRS resource configuration to UE.

[0133] In some embodiments, when a UE accesses base station A, base station A may configure SRS resources for the UE and send the SRS resource configuration to the UE, so that the UE can subsequently send SRS to base station A according to the SRS resource configuration. The SRS resource configuration includes the period of sending SRS, time slot position, bandwidth configuration, power configuration, etc.

[0134] For example, base station A may carry the SRS resource configuration in an RRC connection reconfiguration message 41 and send the RRC connection reconfiguration message 41 to the UE.

[0135] In some other embodiments of the present application, the SRS resource configuration is included in the first information. The RRC connection reconfiguration message 41 may also be referred to as a first RRC connection reconfiguration message.

[0136] S403: UE sends SRS to base station A.

[0137] Exemplarily, the UE may send the SRS to the base station A according to the SRS resource configuration in S402.

[0138] Correspondingly, after receiving the SRS, base station A may continue the process in S404.

[0139] S404. Base station A measures SRS to determine current channel quality 2.

[0140] In the embodiment of the present application, after receiving the SRS, the base station A measures the SRS to determine the current channel quality 2, so that the base station A can schedule and allocate wireless resources according to the channel quality 2 later.

[0141] For example, base station A can obtain current channel state information by measuring the received SRS. The channel state information may include received signal strength and / or signal-to-noise ratio, etc. Base station A can determine channel quality 2 in the current uplink according to the channel state information.

[0142] In this embodiment, after determining the current channel quality 2, base station A may adjust the scheduling and allocation of uplink radio resources for the UE according to the channel quality 2.

[0143] In other embodiments of the present application, the channel quality 2 may also be referred to as the second channel quality.

[0144] The following takes the example of UE requesting base station A for radio resources to transmit data to illustrate the manner in which base station A implements scheduling and allocation of uplink radio resources.

[0145] S405. UE sends SR to base station A.

[0146] Exemplarily, the SR is used to request radio resources for data transmission from base station A. The UE may send the SR to base station A when data transmission is required.

[0147] S406. Base station A sends an uplink scheduling grant D to the UE according to channel quality 2.

[0148] Exemplarily, after receiving the SR, the base station A may allocate radio resources 3 to the UE according to the current channel quality 2, and send an uplink scheduling grant D to the UE. The uplink scheduling grant D includes allocation information of the radio resources 3.

[0149] In this example, when the current channel quality 2 is poor, the radio resources 3 allocated by base station A to the UE are relatively small. At the same time, base station A reduces the order of the modulation method and the order of MCS in the downlink. On the contrary, when the current channel quality 2 is relatively good, base station A allocates more radio resources 3 to the UE. At the same time, base station A increases the order of the modulation method and the order of MCS in the downlink.

[0150] In other embodiments of the present application, wireless resource 3 may also be referred to as a third wireless resource.

[0151] S407. UE sends uplink data 3 to base station A.

[0152] Exemplarily, after receiving the uplink scheduling grant D, the UE may send uplink data 3 to the base station A based on the allocated wireless resources 3 and the adjusted modulation mode and MCS order.

[0153] In other embodiments of the present application, the uplink data 3 may also be referred to as second uplink data.

[0154] In such Figure 4 In the example, the example of base station A sending SRS resource configuration to UE is used for explanation. In other embodiments, base station A does not send SRS resource configuration to UE. In other words, base station A does not configure SRS resources for UE. In this embodiment, UE will not be able to send SRS to base station A. As a result, base station A cannot determine the quality of the current channel.

[0155] In this embodiment, since base station A does not receive the SRS as shown in S403, base station A cannot determine the current channel quality based on the SRS. At this time, base station A will reduce the allocation and scheduling of wireless resources in the uplink, thereby reducing the data transmission rate in the uplink, which will also cause the UE to experience communication jams.

[0156] To solve the above problems, an embodiment of the present application provides a communication processing method and a terminal. Based on the method, when it is detected that the base station has not sent the configuration of physical resource 1 to the UE, the UE can send UE auxiliary information 1 to the base station. Among them, the UE auxiliary information 1 can carry request A. Request A is used to request the base station to configure physical resource 1 for the UE. The physical resource 1 is used to transmit at least one of SR, CSI and SRS. In this way, the base station can configure physical resource 1 for the UE after receiving the UE auxiliary information 1.

[0157] In this way, the UE can obtain more wireless resources when transmitting data with the base station, thereby improving the efficiency of UE data transmission and improving the problem of communication interruption.

[0158] In some other embodiments of the present application, UE assistance information 1 may also be referred to as first UE assistance information. Physical resource 1 may also be referred to as first physical resource.

[0160] like Figure 5 As shown, the program may include:

[0161] S501: An RRC connection is established between UE and base station A.

[0162] S502: UE sends SR to base station A.

[0163] S503: When the UE determines that the number of SR transmission times reaches the maximum number, the UE releases the first SR resource.

[0164] In the embodiment of the present application, the implementation method of S501 to S503 may correspond to the implementation method of S201 to S203. For the specific content, please refer to the description in A201 to S203, which will not be repeated here.

[0165] S504. UE starts counter 1.

[0166] In some embodiments of the present application, the UE is configured with a counter 1. The counter 1 is used to record the number of times the UE initiates a random access procedure to the base station A to request for radio resources.

[0167] In other embodiments of the present application, the counter 1 may also be referred to as a first counter.

[0168] S505. UE initiates random access process 1 to base station A.

[0169] Exemplarily, when the UE needs to send data in the uplink and the UE is not configured with available SR resources, it can initiate a random access process 1 to base station A to obtain wireless resources for data transmission. In addition, the specific implementation method of the UE initiating the random access process 1 to base station A can refer to the description in S204, which will not be repeated here.

[0170] In this example, the UE may start the counter 1 when initiating the random access procedure 1 to the base station A for the first time.

[0171] For example, after sending a random access request 1 to base station A, the UE may start the counter 1.

[0172] S506. UE sends uplink data 2 to base station A.

[0173] In combination with the description in the above S204, the UE may obtain the uplink scheduling grant C by initiating a random access process to the base station A. Based on the uplink scheduling grant C, the UE may send uplink data 2 to the base station A on the designated radio resources.

[0174] S507: The UE increases the value of counter 1 by 1.

[0175] Exemplarily, after completing the process of sending uplink data 2, the UE may add 1 to the value of counter 1 and continue to execute the process in S508.

[0176] S508. The UE determines whether the value of counter 1 exceeds a preset threshold.

[0177] In an embodiment of the present application, after executing the process of adding 1 to the value of counter 1, the UE also needs to determine whether the value of counter 1 exceeds a preset threshold.

[0178] As an implementation manner, the UE determines that the value of counter 1 exceeds a preset threshold. In this implementation manner, the UE may continue to perform the operation in S509.

[0179] As another implementation, the UE determines that the value of counter 1 is less than a preset threshold. In this implementation, when the UE needs to perform data transmission again, the processing in S505 to S507 may be repeatedly performed.

[0180] In other embodiments of the present application, the preset threshold may also be referred to as a first preset threshold.

[0181] S509 , UE sends UE auxiliary information 51 to base station A.

[0182] Exemplarily, the UE assistance information 51 may include UEAssistanceInformation. When the UE determines that the value of counter 1 exceeds a preset threshold, the UE sends the UE assistance information 51 to the base station A. The UE assistance information 51 carries a request A1. The request A1 is used to request the base station A to configure SR resources. The request A1 is included in the request A.

[0183] Correspondingly, after receiving the UE auxiliary information 51, base station A can perform the operation in S510.

[0184] S510. Base station A sends SR resource configuration to UE.

[0185] In some embodiments of the present application, in response to request A1 in UE auxiliary information 51, base station A may send SR resource configuration to UE. The SR resource configuration may include a period for sending SR, a time slot position, and PUCCH resource configuration.

[0186] As an implementation, base station A may carry the SR resource configuration in the RRC connection reconfiguration message 52, and send the RRC connection reconfiguration message 52 to the UE to send the SR resource configuration to the UE.

[0187] It should be noted that, in some embodiments of the present application, when the UE receives the SR resource configuration sent by base station A, the UE can turn off counter 1.

[0188] In some embodiments of the present application, after obtaining the SR resource configuration, the UE can continue to execute the following with the base station A: Figure 1 The interaction from S102 to S106 in the above method enables the UE to request wireless resources for data transmission by sending an SR to the base station A. This avoids the UE from continuing to obtain wireless resources for data transmission through a random access process in the future. This can improve the efficiency of UE data transmission and improve the user's communication experience.

[0189] exist Figure 5 In the description of FIG. 1 , the UE sends UE auxiliary information 51 to the base station A when the value of the counter 1 exceeds the preset threshold. In other embodiments of the present application, refer to Figure 6 , after initiating random access procedure 2 to base station A for the first time and waiting for T6 duration, UE can send UE auxiliary information 51 to base station A. In this T6 duration, UE does not receive SR resource configuration sent by base station A.

[0217] Exemplarily, after receiving the RRC connection reconfiguration message 71, the UE can identify whether the RRC connection reconfiguration message 71 carries the CSI report resource configuration.

[0218] In this example, the UE is configured with a timer 2. The timing duration of the timer 2 is T7. When the RRC connection reconfiguration message 71 does not include the CSI report resource configuration, the UE starts the timer 2.

The CSI report resource configuration may include a period of reporting CSI reports, a time slot position, and a PUCCH or PUSCH resource configuration, etc. In this way, the UE can subsequently send a CSI report to base station A based on the CSI report resource configuration to feedback the current channel quality.

[0225] As an implementation, base station A may carry the CSI report resource configuration in the RRC connection reconfiguration message 73, and send the CSI report resource configuration to the UE by sending the RRC connection reconfiguration message 73 to the UE. In some other embodiments of the present application, the RRC connection reconfiguration message 73 may also be referred to as a first RRC connection reconfiguration message.

This allows the UE and base station A to use more wireless resources for downlink data transmission, thereby improving the efficiency of UE data transmission and improving the user's communication experience.

For example, EPS bearer management, authentication, mobility management in the idle state (i.e., ECM-IDLE state) of the EPS connection management mode, responsible for generating paging messages for UEs in the ECM-IDLE state, security control and other functions.

[0250] The RRC layer 902 is a high-level layer of the control plane, which is mainly responsible for controlling L1 / L2 to complete air interface resource transmission and providing information transmission services for the NAS layer 901. Exemplarily, the RRC layer 902 can be used to manage functions such as system message broadcasting, RRC connection control, mobility management, and measurement configuration reporting.

The PDCP layer 903 also provides in-order submission and duplicate packet detection functions to the upper layer. In the control plane, the PDCP layer 903 provides signaling transmission services for the upper layer RRC, implements encryption and consistency protection of RRC signaling, and implements decryption and consistency checking of RRC signaling in the reverse direction.

The RLC layer 904 mainly provides radio link control functions and provides services such as segmentation, retransmission control, and on-demand transmission for the upper layer. The RLC layer 904 includes three transmission modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM), and mainly provides functions such as error correction, segmentation, and reassembly.

[0253] MAC is the abbreviation of Media Access Control, and the MAC layer 905 is the media access control layer. The MAC layer 905 is used to provide mapping between logical channels and transport channels; multiplex MAC SDUs from one or more logical channels into a transport block and pass it to the PHY layer 906; demultiplex the transport block from the PHY layer 906 into multiple MAC SDUs and pass them to one or more logical channels; report scheduling information; perform error correction through HARQ; manage the priority between users through dynamic scheduling; manage logical channel priority, etc.

[0254] The PHY layer 906 is the physical layer. The PHY layer 906 provides mechanical, electrical, functional and regulatory characteristics for creating, maintaining and dismantling the physical link required for data transmission. The physical layer can be used to ensure that the original data can be transmitted on various physical media.

[0255] like Fig. 9 As shown, in the embodiment of the present application, the above NAS layer 901, RRC layer 902, PDCP layer 903, RLC layer 904, MAC layer 905, and PHY layer 906 can be integrated in the first chip module of the terminal. For example, the first chip module can be a modem of the terminal.

[0256] In addition, in some embodiments, an application layer 907 may be provided in the terminal. The application layer 907 may be provided on the upper layer of the NAS layer 901. The application layer may be used to process and judge the signaling from the NAS layer, and send communication signaling and data to the NAS layer.

[0257] In such Fig. 9 In the example of , the application layer 907 can be set in the second chip module of the terminal. For example, the second chip module can be an application processor (Application Processor Unit, referred to as APU or AP) of the terminal.

[0258] In other embodiments, the application layer 907, the NAS layer 901, the RRC layer 902, the PDCP layer 903, the RLC layer 904, the MAC layer 905, and the PHY layer 906 may also be in the same chip module.
