[0045] The embodiments of this application can be used in wireless networks of different standards. Wireless access networks may include different communication nodes in different systems. The wireless network system includes a base station and multiple user devices. The base station communicates wirelessly with each of the multiple user devices.

[0046] First, it should be noted that in the embodiments of this application, the base station can be a device capable of communicating with a user terminal. The base station can be any device with wireless transceiver capabilities, including but not limited to: NodeB, eNodeB, base station in a 5G communication system, base station in a future communication system, access node in a WiFi system, wireless relay node, wireless backhaul node, etc. The base station can also be a wireless controller in a cloud radioaccess network (CRAN) scenario; the base station can also be a small cell, transmission reference point (TRP), etc., and this embodiment of the application is not limited to these.

[0048] Rel-16 introduces downlink channel quality measurement and reporting functions for anchored / non-anchored carriers in connected mode. For connected downlink channel quality reporting, once triggered, the corresponding carrier will be measured and reported.

[0049] The carrier whose quality is measured and reported is Msg4 or a carrier configured for dedicated transmission by subsequent reconfiguration signaling. For the base station to trigger this function for connected terminals, the terminal needs to report its capability to support this function (cqi-reporting) to the base station. For terminals with this capability, the base station triggers the terminal to report downlink channel quality via a new MAC CE command when it needs to obtain the terminal's downlink channel quality. Upon receiving the triggering MAC CE command, the terminal performs downlink channel quality measurement. When a UL grant becomes available, the terminal uses that UL grant to complete the reporting.

[0050] Format of MAC CE for downlink channel quality reporting Figure 1 As shown, this MAC CE contains 4 reserved bits R (set to 0) and a QualityReport field with a length of 4 bits.

[0051] The QualityReport supports 12 possible values, taken from the set {1,2,4,8,16,32,64,128,256,512,1024,2048}, where each value corresponds to a certain number of repetitions of an NPDCCH.

[0052] The codepoint / index is the LCID value of the MAC subheader used for MAC CE quality reporting: the LCID value is UL-SCH.

[0053] Codepoint / Index LCID value 10001 DCQR and AS RAI

[0054] The current quality report shows the number of repetitions of the control channel, which the base station uses to determine the number of repetitions. If it is necessary to determine the modulation scheme for the service channel based on its quality value, the terminal needs to report an extended quality value, i.e., the quality of the service channel.

[0055] In one embodiment, this embodiment provides a quality type determination method, which is applied to a first node, such as... Figure 2 As shown, the quality type determination method provided in this embodiment mainly includes steps S11 and S12.

[0056] S11. Receive the trigger media access control layer control unit (MAC CE) sent by the second node;

[0057] S12. Determine the quality type to be sent based on the triggered MAC CE.

[0058] In one embodiment, the triggering of the MAC CE includes one or more of the following:

[0059] Share the existing quality reporting trigger MAC CE;

[0060] Reuse the existing quality reporting trigger MAC CE;

[0061] Introducing a new trigger MAC CE.

[0062] In this embodiment, the first node is any of the aforementioned base stations. The second node is any of the aforementioned terminals.

[0063] In this embodiment, the method for a base station to trigger a terminal to report quality values ​​includes: sharing an existing quality reporting trigger MAC CE; reusing an existing quality reporting trigger MAC CE and distinguishing the trigger reporting quality type; and introducing a new MAC CE to trigger extended quality reporting.

[0064] In one embodiment, when the triggering MAC CE is a triggering MAC CE that shares existing quality reporting, the quality type to be transmitted is determined based on the triggering MAC CE signaling, including one of the following methods:

[0065] The quality type to be sent is determined based on the relationship between RSRP value and threshold.

[0066] The quality type to be transmitted is determined based on the number of repetitions in the control channel;

[0067] The quality type to be transmitted is determined based on the number of repetitions in the data channel.

[0068] In this embodiment, determining the transmission quality type based on the relationship between the RSRP value and the threshold includes the following two methods: One method is to determine the transmission quality type as a control channel if the RSRP value is greater than or equal to the threshold, and as a service channel if the RSRP value is less than the threshold. The other method is to determine the transmission quality type as a service channel if the RSRP value is greater than or equal to the threshold, and as a control channel if the RSRP value is less than the threshold. It should be noted that these two methods are parallel technical solutions, and either method can be chosen for implementation.

[0069] In this embodiment, determining the transmission quality type based on the control channel repetition count includes the following two methods: One method is to determine the transmission quality type as a control channel if the control channel repetition count is greater than or equal to a repetition threshold; otherwise, it is determined as a service channel. The other method is to determine the transmission quality type as a service channel if the control channel repetition count is greater than or equal to a repetition threshold; otherwise, it is determined as a control channel. It should be noted that these two methods are parallel technical solutions, and either method can be chosen for implementation.

[0070] In this embodiment, determining the transmission quality type based on the data channel repetition count includes the following two methods: One method is to determine the transmission quality type as a control channel if the data channel repetition count is greater than or equal to a repetition threshold, and as a service channel if the data channel repetition count is less than the repetition threshold. The other method is to determine the transmission quality type as a service channel if the data channel repetition count is greater than or equal to the repetition threshold, and as a control channel if the data channel repetition count is less than the repetition threshold. It should be noted that these two methods are parallel technical solutions, and either method can be chosen for implementation.

[0071] The specific value of the aforementioned threshold and the repeat threshold can be determined according to the actual situation. In this embodiment, the specific value of the threshold is not limited.

[0072] In this embodiment, the existing quality reporting trigger MAC CE is used; including the following methods:

[0073] The terminal determines whether to report the quality value of the original control channel or the extended service channel. If the Channel Quality Indicator (CQI) index is 0, or the quality report corresponding to the CQI is out of range, the terminal reports the quality of the control channel. If the CQI index is greater than or equal to 1, the terminal reports the quality value of the service channel.

[0074] In one embodiment, if the triggering MAC CE is a reused triggering MAC CE for existing quality reporting, the bit bits in the subheader of the triggering MAC CE are used to determine the quality type to be transmitted.

[0075] In one embodiment, the quality type to be reported is determined using bits in the subheader of the triggering MAC CE, including: when the bits in the subheader of the triggering MAC CE are in a first state, indicating that the quality type to be transmitted is control channel quality; and when the bits in the subheader of the triggering MAC CE are in a second state, indicating that the quality type to be transmitted is traffic channel quality.

[0076] Reuse the existing quality reporting trigger MAC CE and distinguish the trigger reporting quality type. The subheader of the existing trigger reporting MAC CE has three bits, R, F2, and E, which can be used to distinguish the trigger reporting quality type.

[0077] For example, a single bit, such as R, F2, or E, can be used to indicate the quality type triggering the report. Setting it to '0' indicates reporting the original control channel quality value, while setting it to '1' indicates reporting the extended service channel quality value. Alternatively, two bits, such as R+F2, R+E, or F2+E, can be used to indicate the reporting content: 00 for reporting the original control channel quality value; 01 for reporting the extended service channel quality value; 10 for reporting both the original control channel quality value and the extended service channel quality value; and 11 for reporting either the original control channel quality value or the extended service channel quality value.

[0078] In one embodiment, if the triggering MAC CE is a new triggering MAC CE, the quality type to be transmitted is determined to be traffic channel quality.

[0079] In this embodiment, a new MAC CE is introduced to trigger extended service channel quality reporting; that is, a new logical channel identifier (LCID) value is introduced to identify the subheader of this MAC CE, such as selecting a value from the existing remaining LCID values, such as '01111', and also including R, F2, and E fields.

[0080] In one embodiment, this embodiment provides a quality value transmission method, the method being applied to a first node, such as... Figure 3 As shown, the quality value transmission method provided in this embodiment mainly includes steps S21 and S22.

[0081] S21. Determine the service channel quality value;

[0082] S22. Use the reported MAC CE to send the service channel quality value to the second node.

[0083] In one embodiment, the reporting MAC CE includes: reporting MAC CE using existing control channels; and / or, reporting MAC CE using new transmit service channel quality values.

[0084] In one embodiment, when the reported MAC CE is a reported MAC CE that reuses an existing control channel, the format of the reported MAC CE includes: Access Layer Release Assist Indication AS RAI, Reserved R, and Channel Quality Value.

[0085] In one embodiment, the format of the reported MAC CE includes a reserved R and a channel quality value. When the reserved R is in a second state, the channel quality value is used to report the service channel quality value; when the reserved R is in a first state, the channel quality value is used to report the control channel quality value.

[0086] In this implementation, the MAC CE reported by the existing control channel is reused; the format of the MAC CE includes a 2-bit Access Stratum Release Assistance Indication (AS RAI), a 2-bit Reserved R, and a 4-bit control channel quality value.

[0087] The specific reuse methods are as follows:

[0088] Use 2 reserved R bits, or any R bits, to indicate the type of reported quality. For example, setting any R bit to '0' indicates that the 4 bits are used to report the quality value of the original control channel; setting it to '1' indicates that the 4 bits are used to report the quality value of the extended service channel.

[0089] The first reserved R bit is used to indicate the type of reported quality; if set to '0', it indicates that the 4 bits are used to report the quality value of the original control channel; if set to '1', it indicates that the following 5 bits are used to report the quality value of the extended service channel.

[0090] In one embodiment, when the reported MAC CE is a new transmit traffic channel quality value, the reported MAC CE includes: the LCID value of the new MAC CE subheader.

[0091] In one embodiment, the new MAC CE format for reporting the transmission service channel quality value includes one of the following forms:

[0092] AS RAI, reserved space, service channel quality;

[0093] Reserved space, service channel quality;

[0094] Quality of control channels and quality of traffic channels.

[0095] In this implementation, a new MAC CE for reporting extended quality values ​​of the service channel is introduced; this includes the introduction of a new LCID value for the MAC CE subheader, such as '01111'. The specific format of the MAC CE includes the following methods;

[0096] MAC CE includes 2 bits of AS RAI, 2 reserved bits, and 4 quality of traffic channel extension;

[0097] MAC CE includes 2 bits of AS RAI, 1 reserved bit, and 5 quality of traffic channel extension;

[0098] MAC CE includes 2 bits of AS RAI, 3 reserved bits, and 3 quality of traffic channel extension;

[0099] The MAC CE includes 4 reserved bits and 4 service channel extension quality;

[0100] MAC CE includes 4 bits of extended channel quality and 4 bits of traffic channel extended quality;

[0101] In one embodiment, the method further includes: receiving a semi-persistent scheduling (SPS) resource sent by a second node, the SPS resource being used to carry the reported MAC CE.

[0102] In one embodiment, the SPS resource includes one or more of the following: an SPS shared by periodic reporting of service channel quality values ​​and periodic reporting of buffer status BSR; and an independent SPS for periodic reporting of service channel quality values.

Furthermore, this SPS resource can be used for reporting when there is a need to report service channel quality, a need to report BSRs, or a need to report both service channel quality and BSRs.

[0110] This includes two independent SPSs: one for periodically reporting the extended quality value of the service channel and the other for periodically reporting the BSR; the other includes the configuration of the uplink semi-static scheduling interval semiPersistSchedIntervalUL and the network temporary identifier semiPersistSchedC-RNTI information applied to the SPS.

[0165] Table 1

[0166]

[0167]

[0168] Here, Rateij represents the bitrate defined when the number of repetitions is i (i = 1, 2, 4); in addition, the bitrate can be configured with the same bitrate value when the number of repetitions is different, such as Rate11 = Rate21.

[0170] Table 2

[0171]

[0172] In one applicable implementation, this embodiment provides a method for a base station to trigger a terminal to report service channel quality values.

[0173] The base station triggers the terminal to report the service channel quality value in the following three ways;

[0174] 1. Share the existing quality reporting trigger MAC CE; including the following methods:

[0175] The terminal determines whether to report the quality value of the original control channel or the extended service channel. If the Channel Quality Indicator (CQI) index is 0, or the quality report corresponding to the CQI is out of range, the terminal reports the control channel quality value; otherwise, it reports the service channel quality value. In other words, if the corresponding CQI index is greater than or equal to 1, the service channel quality value is reported.

[0176] If the base station broadcasts the threshold values ​​for the control channel quality value and / or the extended quality value of the service channel (such as the threshold value of RSRP), or if the base station sends the threshold values ​​for the control channel quality value and / or the extended quality value of the service channel via RRC, the terminal determines the type of quality to be reported based on the results of the quality measurement and the setting of the threshold values.

[0177] 2. Reuse existing quality reporting trigger MAC CEs and distinguish the quality types of trigger reports;

[0178] The existing subheader of the triggered MAC CE has three bits, R, F2, and E, which can be used to distinguish the quality type of the triggered report; the LCID of the existing quality reporting triggered MAC CE subheader is shown in Table 3.

[0179] Table 3

[0180] Codepoint / Index LCID value 10001 DCQR Command

[0181] The format of the subheader is as follows: Figure 6 As shown.

[0182] For example, a single bit, such as R, F2, or E, can be used to indicate the quality type triggering the report. Setting it to '0' indicates reporting the original control channel quality value, and setting it to '1' indicates reporting the extended service channel quality value. Alternatively, two bits, such as R+F2, R+E, or F2+E, can be used to indicate the reporting content: 00 reports the original control channel quality value; 01 reports the extended service channel quality value; 10 reports both the original control channel quality value and the extended service channel quality value; and 11 reports either the original control channel quality value or the extended service channel quality value.

[0183] 3. Introduce a new MAC CE to trigger extended service channel quality reporting.

[0184] A new Logical Channel Identifier (LCID) value is introduced to identify the subheader of this MAC CE. For example, a value is selected from the existing remaining LCID values, such as '01111'. It also includes the R, F2, and E fields.

[0185] The LCID of the subheader that triggers the MAC CE for quality reporting is shown in Table 4.

[0186] Table 4

[0187] Codepoint / Index LCID values 01111 extendDCQR command

[0188] In one application implementation, a method for reporting extended service channel quality values ​​is provided, including the following two methods:

[0189] 1. Reuse the MAC CE reported by the existing control channel.

[0190] The MAC CE format includes a 2-bit Access Stratum Release Assistance Indication (AS RAI), a 2-bit Reserved R, and a 4-bit Control Channel Quality value.

[0191] The LCID of the subheader of this MAC CE is shown in Table 5.

[0192] Table 5

[0193] Codepoint / Index LCID values 10001 DCQR and AS RAI

[0194] The format of MAC CE is as follows Figure 7 As shown.

[0195] The specific reuse methods are as follows:

[0196] Use 2 reserved R bits, or any R bits, to indicate the type of reported quality. For example, setting any R bit to '0' indicates that the 4 bits are used to report the quality value of the original control channel; setting it to '1' indicates that the 4 bits are used to report the quality value of the extended service channel.

[0197] The first reserved R bit is used to indicate the type of reported quality; if set to '0', it indicates that the 4 bits are used to report the quality value of the original control channel; if set to '1', it indicates that the following 5 bits are used to report the quality value of the extended service channel.

[0198] 2. Introduce a new MAC CE for reporting extended service channel quality values.

[0199] This includes introducing a new LCID value for the MAC CE subheader, such as '01111'. The specific format of the MAC CE includes the following methods;

[0200] The MAC CE format includes 2 bits of AS RAI, 2 reserved bits, and 4 quality of traffic channel extension.

[0201] The MAC CE format includes 2 bits of AS RAI, 1 reserved bit, and 5 quality of traffic channel extension.

[0202] The MAC CE format includes 2 bits of AS RAI, 3 reserved bits, and 3 quality bits for traffic channel extension.

[0203] The MAC CE format includes 4 reserved bits and 4 service channel extension quality bits.

[0204] The MAC CE format includes 4 bits of extended channel quality and 4 service channel extension quality.

[0205] In one application implementation, the base station is configured with semi-persistent scheduling (SPS) resources for periodically reporting extended service channel quality values.

[0206] The base station is configured with semi-persistent scheduling (SPS) resources for periodically reporting service channel spread quality values, including the following methods:

[0207] 1. Configure the SPS for periodic reporting of service channel extended quality values.

[0208] The SPS that configures the periodic reporting of service channel extended quality values ​​includes configuring the uplink semi-static scheduling interval (semiPersistSchedIntervalUL) and the network temporary identifier (semiPersistSchedC-RNTI) information applied to the SPS.

[0209] 2. Configure the SPS shared by the periodic reporting of service channel extended quality values ​​and the periodic reporting of buffer state reports (BSR);

[0210] This includes configuring the uplink semi-static scheduling interval (semiPersistSchedIntervalUL) and applying network temporary identifier (semiPersistSchedC-RNTI) information to SPS.

[0211] In addition, when there is a service channel quality value that needs to be reported, or a BSR that needs to be reported, or both the service channel quality value and the BSR need to be reported, this SPS resource can be used for reporting.

[0212] 3. Configure two independent SPSs for periodic reporting of Service Channel Extended Quality Value and BSR.

[0213] This includes configuring the uplink semi-static scheduling interval (semiPersistSchedIntervalUL) and applying network temporary identifiers (semiPersistSchedC-RNTI) information to the SPS. Additionally, when service channel quality or BSR needs to be reported, any SPS resource can be used for reporting.

[0217] ecqi ENUMERATED{supported} OPTIONAL,

[0218] Complete the reporting process during the capability query.

[0219] When a base station needs to obtain terminal capabilities, it sends a UECapabilityEnquiry message to the terminal. The terminal will carry 16QAM capability support information in the UECapabilityInformation message.

[0225] Meanwhile, the base station configures an SNR / RSRP threshold value in SIB2 to report service channel quality. When the measurement result reaches the threshold value, the service channel quality is reported.

[0226] 2. Implicitly enabled in SIB2 messages, such as when configuration information for reporting SNR / RSRP threshold values ​​for service channel quality is available, service channel quality can be reported.
