Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication processing method and terminal. Background Technology

[0002] Currently, in order to ensure the efficiency of data transmission between the UE and the base station, the UE and the base station can interact, allowing the base station to configure radio resources for data transmission for the UE.

[0003] In some implementations, the base station does not allocate radio resources for data transmission to the UE, or allocates too few radio resources to the UE, resulting in low efficiency of data transmission between the UE and the base station, causing communication lag issues for the UE. Summary of the Invention

[0004] This application provides a communication processing method and terminal, which enables the base station to configure wireless resources for data transmission for the UE, 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 this application adopt the following technical solutions:

[0006] A first aspect includes a communication processing method applied to a terminal. The terminal establishes a first Radio Resource Control (RRC) connection with a first access network device. The method includes: sending first UE assistance information. The first UE assistance 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). The method also includes receiving a first RRC connection reconfiguration message. 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 scheme, the UE can obtain the first physical resource by sending the first UE Assistance Information to the first access network device. This enables the UE to subsequently perform at least one of the following: requesting radio resources for data transmission via SR based on the first physical resource, reporting the current channel quality via CSI based on the first physical resource, and sending SRS to the first access network device for channel quality measurement. This provides a guarantee for the UE to subsequently obtain more radio 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 further includes: sending the SR. The SR is used to request uplink data transmission resources from the first access network device. Acquiring first radio resources. The first radio resources are allocated to the terminal by the first access network device when it receives the SR. Based on the first radio resources, sending first uplink data. Thus, the UE can obtain radio resources for data transmission by sending the SR to the first access network device. This ensures the efficiency of data transmission by the UE and avoids communication lag issues for the UE.

[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 indicator (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 transmitted by the first access network device. Based on second radio resources, first downlink data is received. The second radio resources are allocated to the terminal by the first access network device according to the first CQI.

[0010] Based on the above scheme, the UE can send a CSI report to the first access network device to provide feedback on the current channel quality. Upon receiving the CSI report, the first access network device can allocate radio resources for downlink data transmission to the UE based on the current channel quality. This ensures the performance of downlink data transmission for the UE, improves the efficiency of UE data transmission, and enhances 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: transmitting the SRS; and transmitting second uplink data based on a third radio resource. The third radio 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, enabling the first access network device to obtain the current second channel quality by measuring the SRS. The first access network device can then allocate third radio resources for uplink data transmission to the terminal based on the second channel quality, allowing the UE to transmit second uplink data on the third radio resources. This ensures the performance and rate of the terminal during uplink data transmission.

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

[0014] If N exceeds a preset number of times, the second physical resource configured for transmitting the SR is released. A first random access procedure is initiated to the first access network device to acquire the fourth radio resource. Based on the fourth radio resource, the third uplink data is transmitted.

[0015] Optionally, the terminal is configured with a first counter. This first counter is configured to increment by 1 each time the first random access procedure is initiated with the first access network device. The method further includes starting the first counter when the first random access procedure is first initiated with the first access network device. Thus, the terminal can use the first counter to obtain the number of times it has initiated a random access procedure with the first access network device, so that the terminal can perform subsequent processing based on this number.

[0016] Optionally, after initiating the first random access procedure to the first access network device, the method further includes: determining whether the value of the first counter exceeds a first preset threshold. Sending the first UE assistance information includes: sending the first UE assistance information when it is determined that the value of the first counter exceeds the first preset threshold. Therefore, if the terminal initiates a random access procedure to the first access network device more than a preset number of times, it can initiate a first UE assistance information request to transmit the first physical resource (SR). This allows the terminal to subsequently request radio resources for data transmission by sending SR, avoiding the need for the terminal to repeatedly initiate random access procedures to obtain radio resources for data transmission. This allows the terminal to obtain more radio resources for transmission, improving data transmission efficiency.

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

[0018] Therefore, after the terminal initiates a random access procedure with the first access network device for the first duration, it can initiate a first UE Assist Information Request (SR) to transmit the first physical resource. This allows the terminal to subsequently request radio resources for data transmission by sending an SR, avoiding the need for the terminal to repeatedly initiate random access procedures to obtain radio resources for data transmission. Consequently, the terminal can acquire more radio resources for transmission, improving data transmission efficiency.

[0019] Optionally, before sending the first UE assistance information, the method further includes: receiving a second RRC connection reconfiguration message. Sending the first UE assistance information includes sending the first UE assistance information when the second RRC connection reconfiguration message does not include the first information. Therefore, when the terminal is not configured with first physical resources for transmitting CSI reports or SRS, the terminal can request first physical resources for transmitting CSI reports or SRS by sending the first UE assistance information.

[0020] Optionally, the terminal is configured with a second timer. The duration of the second timer is a second duration. Before sending the first UE assistance information, the method further includes: starting the second timer when the second RRC connection reconfiguration message does not include the first information. Sending the first UE assistance information includes: sending the first UE assistance information when the second timer expires. Thus, the terminal can start the second timer when it determines that no first physical resource for transmitting CSI reports or SRS is configured in the terminal. When the second timer expires, the terminal sends the first UE assistance information 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 processors. The memory stores computer program code, including computer instructions, which, when executed by the processor, cause the terminal to perform communication processing methods as provided in the first aspect and any of its possible designs.

[0022] Thirdly, a chip system includes a processor and a communication interface. The processor is used to retrieve and run a computer program stored in a storage medium, performing communication processing methods as provided in the first aspect and any of its possible designs.

[0023] Fourthly, a computer-readable storage medium having stored thereon computer instructions that, when executed by a processor, implement the communication processing method provided in the first aspect and any possible design thereof.

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

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

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

[0038] The technical solutions provided in this application can be applied to various wireless communication networks, such as: Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Universal Mobile Telecommunication System (UMTS), General Packet Radio Service (GPRS), Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A), Worldwide Interoperability for Microwave Access (WiMAX), 5G New Radio networks, and 6G networks. The terms "network" and "system" are interchangeable.

[0039] In the embodiments of this application, a base station (BS) can be a device that communicates with user equipment (UE) or other communication sites such as relay sites, and the base station can provide communication coverage for a specific physical area. For example, a base station can be a Base Transceiver Station (BTS) or Base Station Controller (BSC) in GSM or CDMA; it can also be a Node B (NB) or Radio Network Controller (RNC) in UMTS; it can also be an Evolutionary Node B (eNB or eNodeB) in LTE; it can also be a Next Generation Node B (gNB) in 5G NR; or it can be other access network equipment providing access services in a wireless communication network. This invention is not limited to any particular type.

[0040] Currently, base stations can allocate radio resources for data transmission to UEs, ensuring the efficiency of data transmission by UEs.

[0041] For example, refer to Figure 1 , Figure 1 This diagram illustrates the interaction between a UE and a base station (e.g., base station A) when the UE requests uplink radio resources for data transmission.

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

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

[0044] For example, the UE sends an RRC connection establishment request to base station A. This RRC connection establishment request can be an 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] Next, the UE can establish an RRC connection based on the RRC connection establishment message. In this example, after completing the RRC connection establishment, the UE sends an RRC connection establishment completion message to base station A. For example, this RRC connection establishment completion message can be RRCConnectionComplete.

[0047] Therefore, an RRC connection is established between the UE and base station A.

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

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

[0050] In the embodiments of this application, when the UE needs to transmit data, it can send an SR to base station A based on the RRC connection in S101. This SR is used to request radio resources from base station A for data transmission.

[0051] It is understandable that before the UE sends the SR to base station A, the UE has a corresponding first SR resource configured. This first SR resource is used to transmit the SR. This first SR resource is configured to the UE by base station A.

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

[0053] S103, Base station A sends uplink scheduling authorization A to UE.

[0054] For example, when base station A receives the SR, in response to the SR, it allocates radio resource 1 for data transmission to the UE and sends an uplink scheduling grant A to the UE. The uplink scheduling grant A may include allocation information for radio resource 1. The uplink scheduling grant A is used to indicate to the UE that it can transmit data on radio resource 1.

[0055] For example, radio resource 1 can be a Physical Uplink Shared Channel (PUSCH) resource. Uplink scheduling grant A can be a UL GRANT.

[0056] Accordingly, after receiving uplink scheduling authorization A, the UE can transmit data on the designated radio resource 1 according to uplink scheduling authorization A.

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

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

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

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

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

[0062] S105, Base station A sends uplink scheduling authorization B to UE.

[0063] For example, base station A can configure radio resource 2 for the UE based on the amount of data the UE needs to transmit as indicated in the buffer status report, and send uplink scheduling authorization B to the UE. Uplink scheduling authorization B may include allocation information for radio resource 2. Uplink scheduling authorization B is used to instruct the UE to transmit data on radio resource 2.

[0064] Accordingly, after receiving uplink scheduling authorization B, the UE can transmit data on the designated radio resource 2 according to uplink scheduling authorization B.

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

[0066] For example, after receiving uplink scheduling authorization B, the UE can send uplink data 1 on the designated radio resource 2.

[0067] exist Figure 1 In the example, the UE obtains radio resources for data transmission by sending an SR to base station A. In other embodiments, refer to... Figure 2 , Figure 2 This diagram illustrates another interaction in which a UE requests uplink radio resources 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. The UE establishes an RRC connection with base station A.

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

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

[0072] For example, when a UE needs to transmit data, it can send an SR request for radio resources to base station A based on the configured first SR resource.

[0073] In some situations (such as network congestion), the UE may not receive a timely response from base station A. In such cases, the UE may send SR requests for radio resources to base station A multiple times.

[0074] In existing protocols, the base station can configure the maximum number of times an SR (Signal Response) can be sent to the UE (e.g., sr-TransMax). The UE can increment SR_COUNTER by 1 for each SR sent. Before the next SR transmission, the UE can determine whether SR_COUNTER is less than sr-TransMax.

[0075] Specifically, if SR_COUNTER is less than sr-TransMax and the UE does not receive a response from the base station for the SR, then the physical layer is instructed to "instruct the physical layer to signal the SR on one valid PUCCH resource for SR". Conversely, if SR_COUNTER is greater than or equal to sr-TransMax, the UE can release all SR resources. This release of all SR resources can be initiated by the UE's lower-level layer (e.g., the MAC layer) to the upper-level layer (e.g., the RRC layer).

[0076] The following example, assuming SR_COUNTER is greater than or equal to sr-TransMax, will be used to further illustrate this example.

[0077] S203. When the UE determines that the number of SR transmissions has reached the maximum, it releases the first SR resource.

[0078] Based on the foregoing explanation, the UE can release the first SR resource when it determines that SR_COUNTER is greater than or equal to sr-TransMax. This release of the first SR resource may include releasing the PUCCH resource.

[0079] In this example, when the UE needs to transmit data again, it cannot request radio resources for data transmission by sending an SR because the UE is not configured with SR resources. In this case, the UE can obtain radio resources for data transmission by initiating a random access procedure to base station A.

[0080] S204, The UE initiates random access procedure 1 to base station A.

[0081] For example, when a UE needs to send data and the UE is not configured with available SR resources, it can initiate a random access procedure 1 to base station A in order to obtain radio resources for data transmission.

[0082] For example, a UE can send a random access request 1 to base station A through the Random Access Channel (RACH).

[0083] Correspondingly, when base station A receives random access request 1, it returns random access response 1 to the UE. This random access response 1 carries uplink scheduling grant C. Uplink scheduling grant C carries information about radio resource 1. This uplink scheduling grant C is used to indicate to the UE that data transmission is permitted.

[0084] In other embodiments of this application, the random access procedure 1 may also be referred to as the first random access procedure. The radio resource 1 may also be referred to as the fourth radio resource.

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

[0086] For example, when the UE receives the uplink scheduling grant C carried in the random access response 1, it 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 this application, uplink data 2 may also be referred to as third uplink data.

[0088] It should be noted that, in the embodiments of this application, compared with the radio resource 2 corresponding to uplink scheduling grant B, the radio resource 1 corresponding to uplink scheduling grant C is less, and the amount of data that the UE can transmit using this radio resource is also less.

[0089] In other embodiments of this application, when the UE needs to send data later, it can continue to initiate multiple random access procedures to base station A in order to obtain radio resources for data transmission.

[0090] In such Figure 2 In the example, if the UE fails to acquire radio resources by sending SR (Signal Transfer), it releases the SR resources and initiates a random access procedure with base station A to acquire radio resources for data transmission. Because the UE acquires limited radio resources through the random access procedure, the data transmission rate is low, resulting in communication lag within the UE.

[0091] In other embodiments, the UE is configured with available CSI reporting resources. These CSI reporting 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 base station A based on these CSI reporting resources, providing feedback on the current channel quality. This allows base station A to schedule and allocate downlink radio resources according to the current channel quality, ensuring the performance of downlink data transmission.

[0092] For example, refer to Figure 3 , Figure 3 This illustrates an interaction process between a UE and a base station A for data transmission in the downlink.

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

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

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

[0096] S302, Base station A sends a CSI report on resource configuration to the UE.

[0097] For example, when a UE accesses base station A, base station A configures CSI reporting resources for the UE and sends this CSI reporting resource configuration to the UE. This allows the UE to subsequently report CSI reports to base station A based on the CSI reporting resource configuration. The CSI reporting resource configuration may include the reporting period, time slot location, and PUCCH or PUSCH resource configuration, etc.

[0098] For example, base station A can carry the CSI report resource configuration in the 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 other embodiments of this application, the CSI report resource configuration is included in the first information. This RRC connection reconfiguration message 31 may also be referred to as the first RRC connection reconfiguration message.

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

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

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

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

[0105] CQI_1 is used to indicate the current channel quality. Taking CQI_1 including a first value as an example, generally, the larger the first value, the better the current channel quality. Conversely, the smaller the first value, the worse the channel quality.

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

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

[0108] For example, after determining CQI_1, the UE can send a CSI report to base station A. This CSI report contains CQI_1.

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

[0110] It is understood that, in some embodiments, base station A may periodically send a CSI reference signal A to the UE. This allows the UE to perform processing as described in S304 and S305 upon receiving the CSI reference signal A, thereby enabling periodic feedback of real-time channel quality in the downlink to base station A.

[0111] S306. Based on the CSI report, base station A adjusts the scheduling and allocation of downlink radio resources for the UE.

[0112] For example, after receiving a CSI report, base station A can 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 a first value as an example, a smaller first value corresponds to poorer channel quality in the current downlink. In this implementation, when base station A receives CQI_1 carried in the CSI report, it reduces the allocation of radio resources in the downlink and lowers the order of the modulation scheme and modulation coding scheme (MCS) in the downlink. Conversely, a larger first value corresponds to better downlink quality. In this implementation, when base station A receives CQI_1 carried in the CSI report, it increases the allocation of radio resources in the downlink and increases the order of the modulation scheme and MCS in the downlink.

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

[0115] For example, after completing the processing in S306, base station A can send downlink data to the UE based on the radio resource 3 currently allocated to the UE for transmitting downlink data, as well as the adjusted modulation scheme and MCS order.

[0116] In some other embodiments of this application, the downlink data may also be referred to as first downlink data. Radio resource 3 may also be referred to as second radio resource.

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

[0118] In this embodiment, the UE and base station A can perform the processes described in S303 and S304.

[0119] For example, base station A can send a CSI reference signal B to the UE. Upon receiving the CSI reference signal B, the UE can measure the CSI reference signal B to determine CQI_2. This CQI_2 is used to indicate the current channel quality.

[0120] It should be noted that the specific implementation of this embodiment can be found by referring to... Figure 3 The relevant explanations will not be repeated here.

[0121] Since the UE does not have CSI reporting resources configured, it will be unable to send a CSI report to base station A. In other words, the UE will be unable to send CQ1_2 to base station A by submitting a CSI report.

[0122] In this embodiment, base station A fails to receive the CSI report shown in S305, thus preventing it from acquiring the current channel quality. In this case, base station A reduces the allocation of radio resources in the downlink, and also lowers the order of the modulation scheme and the order of the MCS in the downlink. This results in a lower data transmission rate in the downlink, causing communication lag for the UE.

[0123] For example, referring to Table 1, Table 1 shows the time A during which the UE fails to report a CSI to base station A and the time B during which the UE experiences communication lag when it receives CSI reference signal A as shown in S303. As shown in Table 1, time A includes time T1, time T2, and time T4, and time B includes time T3 and time T5. Among them, time T2 is the same as time T3, and time T4 is the same as time T5.

[0124] In other words, when the UE does not report a CSI report to base station A, base station A will perform processes such as reducing the allocation of radio resources in the downlink, and reducing the order of the modulation scheme and the order of the MCS in the downlink, resulting in a lower data transmission rate in the downlink, which in turn causes communication lag in the UE.

[0125] Table 1

[0126]

[0127] In some other embodiments, the UE is configured with available SRS resources. These SRS resources are used to transmit SRS, so that base station A can determine the current channel quality based on the SRS, and then perform corresponding radio resource scheduling and allocation to ensure the efficiency of data transmission by the UE.

[0128] For example, refer to Figure 4 , Figure 4 This illustrates an interaction process between a UE and base station A for data transmission in the uplink.

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

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

[0131] In this example, S401 is implemented in the same way as S101. For details, please refer to the description in S101. It 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 can configure SRS resources for the UE and send the SRS resource configuration to the UE. This allows the UE to subsequently send SRS to base station A according to the SRS resource configuration. The SRS resource configuration includes the SRS transmission period, time slot location, bandwidth configuration, and power configuration, among other things.

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

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

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

[0137] For example, the UE can send SRS to base station A according to the SRS resource configuration in S402.

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

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

[0140] In the embodiments of this application, after receiving the SRS, base station A measures the SRS to determine the current channel quality 2. This allows base station A to schedule and allocate radio resources based on the channel quality 2.

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

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

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

[0144] The following example illustrates how base station A schedules and allocates uplink radio resources, using the UE requesting data transmission resources from base station A as an example.

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

[0146] For example, this SR is used to request radio resources for data transmission from base station A. When the UE needs to transmit data, it can send an SR to base station A.

[0147] S406. Base station A sends uplink scheduling authorization D to UE based on channel quality 2.

[0148] For example, after receiving the SR, base station A can allocate radio resources 3 to the UE based on the current channel quality 2, and send an uplink scheduling grant D to the UE. The uplink scheduling grant D includes the allocation information for radio resources 3.

[0149] In this example, when the current channel quality 2 is poor, base station A allocates less radio resources 3 to the UE. Simultaneously, base station A reduces the order of the modulation scheme and the order of the MCS in the downlink. Conversely, when the current channel quality 2 is good, base station A allocates more radio resources 3 to the UE. Simultaneously, base station A increases the order of the modulation scheme and the order of the MCS in the downlink.

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

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

[0152] For example, after receiving the uplink scheduling authorization D, the UE can send uplink data 3 to the base station A based on the allocated radio resources 3, the adjusted modulation scheme and the order of the MCS.

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

[0154] In such Figure 4 The example provided illustrates how base station A sends SRS resource configuration to the UE. In other embodiments, base station A does not send SRS resource configuration to the UE. That is, base station A does not configure SRS resources for the UE. In this embodiment, the UE will be unable to send SRS to base station A, thus causing base station A to be unable to determine the current channel quality.

[0155] In this embodiment, because base station A does not receive the SRS as shown in S403, it cannot determine the current channel quality based on the SRS. At this time, base station A will reduce the allocation and scheduling of radio resources in the uplink, resulting in a lower data transmission rate in the uplink, which will also cause communication lag issues for the UE.

[0156] To address the aforementioned issues, this application provides a communication processing method and terminal. Based on this method, when the base station detects that it has not sent the configuration of physical resource 1 to the UE, the UE can send UE assistance information 1 to the base station. This UE assistance information 1 may carry a request A. Request A is used to request the base station to configure physical resource 1 for the UE. This physical resource 1 is used to transmit at least one of SR, CSI, and SRS. This allows the base station to configure physical resource 1 for the UE after receiving the UE assistance information 1.

[0157] In this way, the UE can obtain more radio resources when transmitting data with the base station. This improves the efficiency of UE data transmission and alleviates the problem of communication interruptions.

[0158] In other embodiments of this 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.

[0159] For example, refer to Figure 5 ,by Figure 2 The scenario shown is used as an example. The solution provided in the embodiments of this application will be illustrated with examples.

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

[0161] An RRC connection is established between S501, 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 transmissions has reached the maximum, it releases the first SR resource.

[0164] In the embodiments of this application, the implementation of S501 to S503 can correspond to the implementation of S201 to S203. For details, please refer to the description in A201 to S203, which will not be repeated here.

[0165] S504, UE Startup Counter 1.

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

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

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

[0169] For example, when a UE needs to transmit data in the uplink and has not configured available SR resources, it can initiate random access procedure 1 to base station A in order to obtain radio resources for data transmission. Furthermore, the specific implementation of the UE initiating random access procedure 1 to base station A can be found in the description in S204, and will not be repeated here.

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

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

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

[0173] Based on the description in S204 above, the UE can obtain uplink scheduling authorization C by initiating a random access procedure to base station A. The UE can then send uplink data 2 to base station A on designated radio resources based on this uplink scheduling authorization C.

[0174] S507, UE increments the value of counter 1 by 1.

[0175] For example, after the UE completes the processing of sending uplink data 2, it can increment the value of counter 1 by 1 and continue to execute the processing in S508.

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

[0177] In the embodiments of this application, after the UE performs the process of incrementing the value of counter 1 by 1, it also needs to determine whether the value of counter 1 exceeds a preset threshold.

[0178] In one implementation, the UE determines that the value of counter 1 exceeds a preset threshold. In this implementation, the UE can continue the operation in S509.

[0179] In 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 transmit data again, it can repeat the processing in S505 to S507.

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

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

[0182] For example, UE assistance information 51 may include UEAssistanceInformation. When the UE determines that the value of counter 1 exceeds a preset threshold, it sends UE assistance information 51 to base station A. This UE assistance information 51 carries request A1. Request A1 is used to request configuration of SR resources from base station A. Request A1 is included in request A.

[0183] Accordingly, after receiving the UE assistance 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 this application, in response to request A1 in UE assistance information 51, base station A may send SR resource configuration to the UE. This SR resource configuration may include the period for sending SR, the time slot location, and PUCCH resource configuration, etc.

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

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

[0188] In some embodiments of this application, after obtaining the SR resource configuration, the UE can continue to perform operations with base station A as follows: Figure 1 The interactions in S102 to S106 allow the UE to send an SR request for radio resources to base station A for data transmission. This avoids the UE having to subsequently obtain radio resources through random access procedures for data transmission. Consequently, this improves the efficiency of data transmission for the UE and enhances the user's communication experience.

[0189] exist Figure 5 The description uses the example of the UE sending UE assistance information 51 to base station A when it determines that the value of counter 1 exceeds a preset threshold. In other embodiments of this application, reference is made to... Figure 6 The UE can initiate random access procedure 2 to base station A for the first time and wait for a duration of T6 before sending UE auxiliary information 51 to base station A. During this T6 duration, the UE does not receive SR resource configuration from base station A.

[0190] In some other embodiments of this application, the T6 duration can also be referred to as the first duration.

[0191] like Figure 6 As shown, the scheme includes:

[0192] An RRC connection is established between S601, UE, and base station A.

[0193] S602, UE sends SR to base station A.

[0194] S603. When the UE determines that the number of SR transmissions has reached the maximum, it releases the first SR resource.

[0195] In the embodiments of this application, the implementation of S601 to S603 can correspond to the implementation of S201 to S203. For details, please refer to the description in S201 to S203, which will not be repeated here.

[0196] S604, UE starts timer 1.

[0197] In some other embodiments of this application, the timer 1 may also be referred to as the first timer.

[0198] S605, UE initiates random access procedure 1 to base station A.

[0199] In this example, the UE can be configured with a timer 1, which has a duration of T6. The UE can start this timer 1 when it first initiates the random access procedure 1 to base station A.

[0200] For example, the UE can start the timer 1 after sending a random access request 1 to base station A.

[0201] S606, UE sends uplink data 2 to base station A.

[0202] In this example, the implementation of S605 and S606 can be found in the descriptions of S505 and S506 respectively, and will not be repeated here.

[0203] S607, Timer 1 timer ends.

[0204] S608, The UE sends UE auxiliary information 61 to base station A.

[0205] In some embodiments of this application, when timer 1 expires, the UE can send UE assistance information 61 to base station A. In this embodiment, UE assistance information 61 can be UE assistance information 51 in S509. The specific implementation of the UE sending UE assistance information 61 to base station A can be found in the description in S509, and will not be repeated here.

[0206] S609, Base station A sends SR resource configuration to UE.

[0207] In this example, the implementation of S609 corresponds to S510. For details, please refer to the description in S609, which will not be repeated here.

[0208] and Figure 5 Similar to the example in [example 1], when the UE obtains the SR resource configuration in S609, it can continue to perform actions with base station A, such as [example 2]. Figure 1 The interaction between S102 and S106 in the process enables the UE to subsequently transmit data by sending an SR request for radio resources to base station A.

[0209] refer to Figure 7 , Figure 7 This is a flowchart illustrating another communication processing method provided in an embodiment of this application.

[0210] like Figure 7 As shown, the solution may include:

[0211] S701, UE establishes RRC connection with base station A.

[0212] In the embodiments of this application, the implementation of S701 can correspond to the implementation of S301. For details, please refer to the description in S301, which will not be repeated here.

[0213] S702, Base station A sends an RRC connection reconfiguration message 71 to the UE.

[0214] In the embodiments of this application, during the process of the UE accessing base station A, base station A can send an RRC connection reconfiguration message 71 to the UE. The RRC connection reconfiguration message 71 can carry information cell information A for reconfiguring the UE.

[0215] For example, the information cell A may include the resource configuration of the CSI reference signal A, etc.

[0216] S703. When the UE does not include CSI report resource configuration in RRC connection reconfiguration message 71, start timer 2.

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

[0218] In this example, the UE is configured with Timer 2. The duration of Timer 2 is T7. Timer 2 is started when the UE does not include CSI report resource configuration in RRC connection reconfiguration message 71.

[0219] S704, Timer 2 timer ends.

[0220] S705, The UE sends UE assistance information 72 to base station A.

[0221] For example, the UE may send UE assistance information 72 to base station A when timer 2 expires. This UE assistance information includes request A2. Request A2 is used to request base station A to configure CSI reporting resources. Request A2 is included in request A.

[0222] Accordingly, after receiving the UE assistance information 72, base station A can perform the operation in S706.

[0223] S706, Base station A sends a CSI report on resource configuration to the UE.

[0224] In some embodiments of this application, in response to request A2 in UE assistance information 72, base station A can send CSI report resource configuration to the UE. This CSI report resource configuration may include the CSI report reporting period, time slot location, and PUCCH or PUSCH resource configuration, etc. This allows the UE to subsequently send CSI reports to base station A based on this CSI report resource configuration, providing feedback on the current channel quality.

[0225] As one implementation, base station A can 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. In some other embodiments of this application, the RRC connection reconfiguration message 73 can also be referred to as the first RRC connection reconfiguration message.

[0226] In some embodiments of this application, after receiving the CSI report resource configuration, the UE can continue to perform operations with base station A. Figure 3 The processing steps in S303 to S307 avoid the situation where base station A, unable to obtain the current channel quality, would reduce the allocation of radio resources in the downlink. This allows the UE and base station A to use more radio resources for downlink data transmission, thereby improving the efficiency of UE data transmission and enhancing the user's communication experience.

[0227] refer to Figure 8 , Figure 8 This is a flowchart illustrating another communication processing method provided in an embodiment of this application.

[0228] like Figure 8 As shown, the solution may include:

[0229] S801, UE establishes RRC connection with base station A.

[0230] In the embodiments of this application, the implementation of S801 can correspond to the implementation of S301. For details, please refer to the description in S301, which will not be repeated here.

[0231] S802, Base station A sends an RRC connection reconfiguration message 81 to the UE.

[0232] In an embodiment of this application, during the process of the UE accessing base station A, base station A may send an RRC connection reconfiguration message 81 to the UE. In this embodiment, the RRC connection reconfiguration message 81 does not include SRS resource configuration.

[0233] S803. When the UE does not include SRS resource configuration in RRC connection reconfiguration message 81, start timer 3.

[0234] For example, after receiving the RRC connection reconfiguration message 81, the UE can identify whether the RRC connection reconfiguration message 81 carries SRS resource configuration.

[0235] In this example, the UE is configured with Timer 3. The duration of Timer 3 is T8. Timer 3 is started when the UE does not include SRS resource configuration in RRC connection reconfiguration message 81.

[0236] S804, Timer 3 timer ends.

[0237] S805, UE sends UE assistance information 82 to base station A.

[0238] For example, the UE may send UE assistance information 82 to base station A when timer 3 expires. This UE assistance information includes request A3. Request A3 is used to request configuration of SRS resources from base station A. Request A3 is included in request A.

[0239] Accordingly, after receiving the UE assistance information 82, base station A can perform the operation in S806.

[0240] S806, Base station A sends SRS resource configuration to UE.

[0241] In some embodiments of this application, in response to request A3 in UE assistance information 82, base station A can send SRS resource configuration to the UE. This SRS resource configuration may include the SRS reporting period, timeslot location, and PUCCH or PUSCH resource configuration, etc. This allows the UE to subsequently send SRS to base station A based on this SRS resource configuration.

[0242] As one implementation, base station A can carry the SRS resource configuration in the RRC connection reconfiguration message 83, and send the SRS resource configuration to the UE by sending the RRC connection reconfiguration message 83 to the UE.

[0243] In some embodiments of this application, after receiving the SRS resource configuration, the UE can continue to perform operations with base station A such as... Figure 4 The processing steps in S403 to S407 enable the UE to acquire more radio resources for data transmission. This improves the efficiency of UE data transmission and enhances the user's communication experience.

[0244] It should be noted that, in cases such as Figures 5 to 8 The illustrated scheme uses UE assistance information to request base station A to transmit one of SR, CSI report, and SRS as an example. In other embodiments of this application, the UE assistance information can be used to request base station A to transmit at least one of SR, CSI report, and SRS.

[0245] In the embodiments of this application, such as Figures 5 to 8 The solutions shown can all be applied to terminals with communication functions.

[0246] For example, the terminal in this application embodiment may include at least one of the following: mobile phone, foldable terminal, tablet computer, desktop computer, laptop computer, handheld computer, laptop, ultra-mobile personal computer (UMPC), netbook, cellular phone, personal digital assistant (PDA), augmented reality (AR) device, virtual reality (VR) device, artificial intelligence (AI) device, wearable device, in-vehicle device, smart home device, or smart city device. This application embodiment does not impose any special limitation on the specific type of the terminal.

[0247] As an example, Figure 9 This is a schematic diagram of the composition of a terminal provided in an embodiment of this application.

[0248] like Figure 9 As shown, the terminal may include a multi-layer structure. In this example, the terminal may include a NAS layer 901, an RRC layer 902, a PDCP layer 903, an RLC layer 904, a MAC layer 905, and a PHY layer 906.

[0249] NAS stands for Non-Access Stratum, and NAS layer 901 is also known as the non-access stratum. NAS layer 901 is mainly responsible for providing control and management of the non-access stratum portion. For example, it is responsible for EPS bearer management, authentication, mobility management in the idle state of EPS connection management mode (i.e., ECM-IDLE state), generating paging messages for UEs in ECM-IDLE state, security control, and other functions.

[0250] RRC layer 902 is a higher layer in the control plane, primarily responsible for controlling L1 / L2 to complete air interface resource transmission and providing information transmission services to NAS layer 901. For example, RRC layer 902 can be used to manage functions such as system message broadcasting, RRC connection control, mobility management, and measurement configuration reporting. RRC connection control management includes paging, establishing / modifying / suspending / resuming / releasing RRC connections, initial security activation, establishing / modifying / activating SRB / DRB, cell management in DC and CA modes, and radio link fault recovery.

[0251] PDCP stands for Packet Data Convergence Protocol, and PDCP layer 903 is also known as the Packet Data Convergence Protocol layer. PDCP layer 903 processes RRC messages on the control plane and Internet Protocol (IP) packets on the user plane. For example, on the user plane, after receiving IP data packets from the upper layer, PDCP layer 903 can compress and encrypt the IP data packets before delivering them to RLC layer 904. PDCP layer 903 also provides in-order delivery and duplicate packet detection functions to the upper layer. On the control plane, PDCP layer 903 provides signaling transmission services for upper-layer RRC and implements encryption and consistency protection for RRC signaling, as well as decryption and consistency checks of RRC signaling in the reverse direction.

[0252] RLC stands for Radio Link Control, and RLC layer 904 is the radio link control layer. RLC layer 904 primarily provides radio link control functions, offering services such as segmentation, retransmission control, and on-demand transmission to upper layers. RLC layer 904 includes three transmission modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM), mainly providing error correction, segmentation, and reassembly functions.

[0253] MAC stands for Media Access Control, and MAC layer 905 is the Media Access Control layer. 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 PHY layer 906; demultiplex transport blocks from PHY layer 906 into multiple MAC SDUs and pass them to one or more logical channels; report scheduling information; perform error correction via HARQ; manage user priorities through dynamic scheduling; and manage logical channel priorities, among other functions.

[0254] PHY layer 906 is the physical layer. PHY layer 906 provides mechanical, electronic, functional, and specification characteristics for creating, maintaining, and dismantling the physical links required for data transmission. The physical layer can be used to ensure that raw data can be transmitted over various physical media.

[0255] like Figure 9 As shown in the embodiments of this application, the aforementioned NAS layer 901, RRC layer 902, PDCP layer 903, RLC layer 904, MAC layer 905, and PHY layer 906 can be integrated into the first chip module of the terminal. For example, the first chip module can be the terminal's modem.

[0256] Furthermore, in some embodiments, an application layer 907 may also be provided in the terminal. This application layer 907 may be located above the NAS layer 901. The application layer can be used to process and judge signaling from the NAS layer, and to send communication signaling and data to the NAS layer.

[0257] In such Figure 9 In the example, the application layer 907 can be located in the second chip module of the terminal. For example, the second chip module can be the terminal's application processor (APU or AP).

[0258] In other embodiments, the application layer 907, as well as the NAS layer 901, RRC layer 902, PDCP layer 903, RLC layer 904, MAC layer 905, and PHY layer 906, may also be in the same chip module. This application does not specifically limit the division and configuration of the various protocol layers in the terminal.
