[0041] FIG1 shows a schematic diagram of a communication system provided by an exemplary embodiment of the present application. The communication system includes a terminal device 110 and a network device 120 .

[0044] Terminal device 110 and network device 120 communicate with each other via an air interface technology, such as a Uu interface. For example, there are two communication scenarios between terminal device 110 and network device 120: uplink communication and downlink communication. Uplink communication refers to the transmission of signals from terminal device 110 to network device 120; downlink communication refers to the transmission of signals from network device 120 to terminal device 110.

[0045] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G mobile communication system, NR system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Terrestrial Networks (TN) system, Non-Terrestrial Networks (NTN) system, Wireless Local Area Network (WLAN) system. Networks, WLAN), Wi-Fi, cellular IoT systems, cellular passive IoT systems, and can also be applied to subsequent evolution systems of 5G NR systems, as well as B5G, 6G and subsequent evolution systems.

[0046] In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. Among them, the 5G mobile communication system may include non-standalone networking (NSA) and / or standalone networking (SA). The technical solutions provided in the embodiments of the present application may also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device to device (D2D) network, machine to machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network may include, for example, the Internet of Vehicles. Among them, the communication methods in the Internet of Vehicles system are collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything). For example, the V2X may include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication or vehicle to network (V2N) communication, etc.

[0047] In related technologies, 5G systems support multiple methods for reporting uplink measurement information, including periodic reporting (also known as semi-static reporting), semi-persistent reporting, and aperiodic reporting. For periodic reporting or semi-persistent reporting, the terminal device performs measurements based on the signals periodically sent by the network device, obtains measurement information within the current period, and sends the measurement information using predetermined periodic resources.

[0048] Because 5G system design prioritizes factors like system capacity and transmission latency, overall 5G system power consumption is high. Subsequent 6G systems will further consider low-power design. From the perspective of terminal devices transmitting measurement information, minimizing the transmission of invalid information can help reduce power consumption.

[0049] Based on this, an embodiment of the present application provides a method for sending measurement information, as shown in Figure 2. The method is executed by a terminal device and includes:

[0050] Step 220: When the first condition is met, the first measurement information is not measured and / or the first measurement information is not sent; wherein the first measurement information is obtained based on the measurement result of the first signal, and the first measurement information is preconfigured to be sent on the first time domain resource.

[0051] In some embodiments, the first measurement information is obtained by measuring the first signal.

[0052] In some embodiments, the first signal is sent by the network device to the terminal device. For example, the first signal includes a downlink reference signal sent by the network device to the terminal device. By way of example and not limitation, the first signal includes a channel state information reference signal (CSI-RS). Alternatively, the first signal includes tracking reference information (TRS).

[0053] The network device may send the first signal to the terminal device in a periodic or semi-continuous manner.

[0054] In some embodiments, the first signal may be sent by a terminal device to other terminal devices. In this case, the first signal may include, for example, a sounding reference signal (SRS).

[0055] In some embodiments, the first signal is used to measure and obtain first measurement information. For example, a CSI-RS is used to measure and obtain measurement information related to channel state information.

[0056] In some embodiments, the method further includes receiving a first signal. It should be understood that the terminal device receives the first signal before step 220. If the first signal is periodically transmitted by the network device to the terminal device, the terminal device periodically receives the first signal. If the first signal is semi-continuously transmitted by the network device to the terminal device, the terminal device semi-continuously receives the first signal.

[0057] In some embodiments, when the first condition is met, the first measurement information is not measured, including: when the first condition is met, the first signal is not measured to obtain the first measurement information. It should be understood that in this case, the terminal device does not obtain the first measurement information based on the first signal measurement. When the terminal device does not measure the first signal, the first measurement information obtained based on the first signal measurement will not be sent to the network device. That is, the terminal device does not measure the first measurement information and does not send the first measurement information. Among them, "not measuring the first measurement information" can be understood as "not generating the first measurement information" and can also be understood as "not calculating the first measurement information."

[0058] In some embodiments, if the first condition is met, the first measurement information is not sent. It should be understood that, in one possible scenario, the terminal device has obtained the first measurement information based on the first signal measurement, but if the first condition is met, the first measurement information obtained is not sent; in another possible scenario, the terminal device has not obtained the first measurement information based on the first signal measurement, and if the first condition is met, the terminal device does not measure the first measurement information and does not send the first measurement information.

[0059] In some embodiments, the above situations can be divided into the following two types:

[0060] Case 1: the first measurement information has been obtained based on the first signal measurement; then the terminal device does not send the first measurement information if the first condition is met;

[0061] Case 2: The first measurement information is not obtained based on the first signal measurement; then the terminal device does not measure the first measurement information and does not send the first measurement information when the first condition is met; or the terminal device measures the first measurement information but does not send the first measurement information when the first condition is met.

[0062] In some embodiments, the first measurement information is preconfigured and sent on a first transmission resource. The first transmission resource includes a first time domain resource and / or a first frequency domain resource. Since the embodiments of the present application primarily relate to the measurement timing of the first signal and / or the transmission timing of the first measurement information, the embodiments of the present application are primarily described using the example of the first measurement information being preconfigured and sent on the first time domain resource.

[0063] In some embodiments, the first transmission resource is a periodic resource or a semi-persistent resource. If the first signal is periodically transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also periodic, then the first transmission resource is also periodic. If the first signal is semi-persistently transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also semi-persistent, then the first transmission resource is also semi-persistent.

[0064] In some embodiments, the first measurement information is carried in a measurement report and sent. The measurement report includes one or more types of first measurement information.

[0065] In some embodiments, the first measurement information includes one or more of the following: Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); Rank Indicator (RI); Layer Indicator (LI); Reference Signal Received Power (RSRP); Reference Signal Received Quality (RSRQ); Signal to Interference plus Noise Ratio (SINR); Received Signal Strength Indicator (RSSI). CQI, PMI, RI, and LI can also be understood as channel state information, and RSRP, RSPQ, and SINR can also be understood as interference measurement information.

[0066] In some embodiments, the CQI is used to indicate the quality of the downlink channel. The network device determines appropriate downlink parameters based on the CQI sent by the terminal device. For example, assuming that the CQI value ranges from 0 to 15, a CQI value of 0 indicates the worst downlink channel quality; a CQI value of 15 indicates the best downlink channel quality.

[0067] In some embodiments, the PMI is used to indicate the precoding matrix used by the downlink channel.

[0068] In some embodiments, the RI is used to indicate the number of valid data streams of the downlink channel.

[0069] In some embodiments, LI is used to indicate the number of valid data layers of the downlink channel.

[0070] In some embodiments, RSRP, RSRQ, SINR, and RSSI are all used to indicate the quality of the downlink channel. The values ​​of RSRP, RSRQ, SINR, and RSSI are proportional to the quality of the downlink channel. For example, a larger RSRP value indicates better downlink channel quality; a smaller RSRP value indicates worse downlink channel quality.

[0071] It is worth noting that the first measurement information in the embodiment of the present application can be understood as measurement information to be sent.

[0072] In some embodiments, the first measurement information is represented in numerical form, or in matrix form, or in level form.

[0073] In summary, the method provided in this embodiment utilizes a first condition to control a terminal device to not measure or send the first measurement information when the first condition is met. On the one hand, the terminal device does not measure the first measurement information when the first condition is met, thereby reducing the power consumption generated by measuring the first measurement information and also reducing the power consumption generated by sending the first measurement information. On the other hand, the terminal device does not send the first measurement information when the first condition is met, thereby at least reducing the power consumption generated by sending the first measurement information.

[0074] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0075] Condition 1: The difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value.

[0076] In some embodiments, the first predetermined value is agreed upon by a communication protocol, or the first predetermined value is configured by a network device.

[0077] For example, assuming that the first measurement information is 80dB, the second measurement information is 78dB, and the first predetermined value is 3dB, the difference between the first measurement information and the second measurement information is 2dB. Since 5dB is less than 6dB, it is determined that the first condition is met.

[0078] For example, assuming that the first measurement information is 80dB, the second measurement information is 70dB, and the first predetermined value is 3dB, the difference between the first measurement information and the second measurement information is 10dB. Since 10dB is greater than 3dB, it is determined that the first condition is not met.

[0079] In some embodiments, assuming that the first measurement information is a CQI, the CQI result is indicated by a CQI index value. In some embodiments, the CQI index value corresponds to a modulation and coding scheme (MCS) index value based on a modulation order.

[0080] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 3, and the first predetermined value is 2, then the difference between the first measurement information and the second measurement information is 1. Since 1 is less than 2, it is judged that the first condition is met.

[0081] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 5, and the first predetermined value is 2, then the difference between the first measurement information and the second measurement information is 3. Since 3 is greater than 2, it is judged that the first condition is not met.

[0082] In some embodiments, assuming that the first measurement information is PMI, the result of the PMI is indicated by a precoding matrix index value (index).

[0083] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are the same, it is judged that the first condition is met; when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are different, it is judged that the first condition is not met.

[0084] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1, and the second measurement information also corresponds to a precoding matrix index value of 1, that is, the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are the same, it is judged that the first condition is met.

[0085] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1, and the second measurement information corresponds to a precoding matrix index value of 2, that is, the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are different, it is judged that the first condition is not met.

[0086] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information both belong to a predetermined index value set, it is judged that the first condition is met; when the precoding matrix index value corresponding to the first measurement information does not belong to the index value set where the precoding matrix index value corresponding to the second measurement information is located, it is judged that the first condition is not met.

[0087] Exemplarily, assuming that the first measurement information corresponds to a precoding matrix index value of 1, the second measurement information also corresponds to a precoding matrix index value of 2, and the predetermined index value set is {1, 2, 5}, then the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information both belong to the predetermined index value set, and therefore, it is determined that the first condition is satisfied. Alternatively, it can be understood that the precoding matrix index value corresponding to the first measurement information belongs to the index value set in which the precoding matrix index value corresponding to the second measurement information belongs.

[0088] In some embodiments, matrices corresponding to index values ​​in the same index value set are correlated.

[0089] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information belong to the same index value set, it is considered that the precoding matrix corresponding to the first measurement information and the precoding matrix corresponding to the second measurement information are correlated.

[0090] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1, the second measurement information also corresponds to a precoding matrix index value of 2, and the predetermined index value set is {2, 3, 5}, the precoding matrix index value corresponding to the first measurement information does not belong to the index value set where the precoding matrix index value corresponding to the second measurement information is located, and therefore it is judged that the first condition is not met.

[0091] In some embodiments, assuming that the first measurement information is RI, the result of RI corresponds to the matrix rank of the precoding matrix.

[0092] In some embodiments, when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information are the same, it is judged that the first condition is satisfied; when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information are different, it is judged that the first condition is not satisfied.

[0093] Exemplarily, assuming that the matrix rank corresponding to the first measurement information = 1, and the matrix rank corresponding to the second measurement information = 1, the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information are the same, so it is judged that the first condition is met.

[0094] For example, assuming that the matrix rank corresponding to the first measurement information is 1 and the matrix rank corresponding to the second measurement information is 2, the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information are different, so it is judged that the first condition is not met.

[0095] In some embodiments, the first condition is judged to be satisfied when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information both belong to a predetermined rank number set; and the first condition is judged to be not satisfied when the matrix rank number corresponding to the first measurement information does not belong to the rank number set where the matrix rank number corresponding to the second measurement information belongs.

[0096] For example, assuming that the matrix rank corresponding to the first measurement information is 1, the matrix rank corresponding to the second measurement information is 2, and the predetermined rank set is {1, 2}, then the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information both belong to the predetermined rank set, and therefore, it is determined that the first condition is satisfied. Alternatively, it can be understood that the matrix rank corresponding to the first measurement information belongs to the rank set in which the matrix rank corresponding to the second measurement information belongs.

[0097] In some embodiments, matrices corresponding to matrix ranks in the same rank number set are correlated.

[0098] In some embodiments, when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information belong to the same rank number set, it is considered that the matrix corresponding to the first measurement information and the matrix corresponding to the second measurement information are correlated.

[0099] For example, assuming that the matrix rank corresponding to the first measurement information = 1, the matrix rank corresponding to the second measurement information = 2, and the predetermined rank set is {2, 3}, the matrix rank corresponding to the first measurement information does not belong to the rank set where the matrix rank corresponding to the second measurement information is located, and therefore it is judged that the first condition is not met.

[0100] In some embodiments, the first predetermined value indicates the maximum allowable difference between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value, the difference between the first measurement information and the second measurement information is not significant. If the difference between the first measurement information and the second measurement information is greater than the first predetermined value, the difference between the first measurement information and the second measurement information is significant.

[0101] In an embodiment of the present application, when the difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value, it can be determined that the first measurement information and the second measurement information are not much different, and therefore the first measurement information may not be sent, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption of the terminal device in sending the first measurement information.

[0102] In some embodiments, the second measurement information is obtained by measuring the second signal.

[0103] In some embodiments, the second signal is sent by the network device to the terminal device. For example, the second signal includes a downlink reference signal sent by the network device to the terminal device. By way of example and not limitation, the second signal includes a CSI-RS. Alternatively, the second signal includes a TRS.

[0104] The network device may send the second signal to the terminal device in a periodic or semi-continuous manner.

[0105] In some embodiments, the second signal may be sent by one terminal device to other terminal devices. In this case, the second signal may include an SRS, for example.

[0106] In some embodiments, the second measurement information is sent on a second transmission resource. The second transmission resource includes a second time domain resource and / or a second frequency domain resource. In the embodiments of the present application, the second measurement information is sent on the second time domain resource as an example.

[0107] In some embodiments, the second measurement information is carried in a measurement report and sent. The second measurement information includes one or more of the following: CQI, PMI, RI, LI, RSRP, RSRQ, SINR, and RSSI.

[0108] In some embodiments, the second measurement information is represented in numerical form, or in matrix form, or in level form.

[0109] In some embodiments, the second measurement information and the first measurement information are of the same type of information. Exemplarily, both the first measurement information and the second measurement information are CQIs.

[0110] In some embodiments, the second measurement information corresponds to the same representation as the first measurement information.

[0111] In some embodiments, when multiple first measurement information are preconfigured to be sent on the first time domain resource, the second measurement information is also a plurality of second measurement information corresponding to each piece of the multiple first measurement information. Exemplarily, assuming that the multiple first measurement information includes CQI, PMI, and RI, the second measurement information is also the corresponding CQI, PMI, and RI.

[0112] In some embodiments, the second measurement information is information of the same type as the first measurement information that is sent by the terminal device for the last time before the first time domain resource.

[0113] In some embodiments, only one type of first measurement information is preconfigured for transmission on the first time domain resource. For example, as shown in FIG3 , assume that the first measurement information is a CQI to be reported at time t2, and a PMI was reported at time t1, prior to time t2. Although time t1 is closest to time t2, no CQI was reported at time t1, so the PMI reported at time t1 is not the second measurement information. However, at time t0, prior to time t1, RI, PMI, and CQI, including the CQI, were reported, so the CQI reported at time t0 is considered the second measurement information.

[0114] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple types. For example, as shown in Figure 4, it is assumed that three types of first measurement information are to be reported at time t2, namely RI, PMI and CQI. CQI was reported at time t1 before time t2, so it is considered that the CQI reported at time t1 is the second measurement information corresponding to the CQI to be reported at time t2. PMI was reported at time t0 before time t1, so it is considered that the PMI reported at time t0 is the second measurement information corresponding to the PMI to be reported at time t2. However, there is no second measurement information corresponding to the RI to be reported at time t2 within the preset time period. In some embodiments, the second measurement information is measurement information within a preset time period, and the preset time period includes the second time domain resource.

[0115] It is worth noting that the second measurement information in the embodiment of the present application can be understood as the measurement information that has been sent.

[0116] In some embodiments, the second time domain resource for sending the second measurement information is before the first time domain resource.

[0117] In some embodiments, the second time domain resource includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time domain resource includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiment of the present application includes at least one of a subframe, a time slot, and a symbol. For example, as shown in Figure 5, it is assumed that the first time domain resource 11 is a time domain resource occupying symbol 10 to symbol 13, and the second time domain resource 12 includes 4 time domain units preceding the first time domain resource. For example, the second time domain resource 12 is a time domain resource occupying symbol 4 to symbol 7.

[0118] In some embodiments, the second time domain resource includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the second time domain resource includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the second time domain resource includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located. Exemplarily, as shown in FIG6 , assuming that the time domain unit where the first time domain resource 11 is located is the 4th time slot, the second time domain resource 12 includes 2 time slots preceding the time slot where the first time domain resource 11 is located. For example, the second time domain resource 12 includes the 1st time slot and the 2nd time slot.

[0119] In some embodiments, the second time domain resource includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time domain resource includes Q milliseconds before the starting position of the first time domain resource. Exemplarily, the second time domain resource includes 5 ms before the first time domain resource.

[0120] In some embodiments, the second time domain resource is a resource that is most recently used to send the second measurement information before the first time domain resource.

[0121] In some embodiments, there is only one type of first measurement information preconfigured to be sent on the first time domain resource. For example, as shown in FIG3 , the first time domain resource is the time domain resource corresponding to time t2, and the second time domain resource is the time domain resource corresponding to time t0.

[0122] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple types. Exemplarily, as shown in FIG4 , the first time domain resource corresponding to each first measurement information is the time domain resource corresponding to time t2, the second time domain resource corresponding to the CQI is the time domain resource corresponding to time t1, and the second time domain resource corresponding to the PMI is the time domain resource corresponding to time t0.

[0123] In some embodiments, the first time domain resource and the second time domain resource are adjacent time domain resources, or the first time domain resource and the second time domain resource are non-adjacent time domain resources.

[0124] In some embodiments, the time domain resource lengths corresponding to the first time domain resource and the second time domain resource are the same. For example, the first time domain resource and the second time domain resource are both time domain resources including 4 symbols.

[0125] In some embodiments, the time domain resource lengths corresponding to the first time domain resource and the second time domain resource are different. For example, the first time domain resource is a time domain resource including 3 symbols, and the second time domain resource is a time domain resource including 4 symbols.

[0126] In some embodiments, the time domain interval between the second time domain resource and the first time domain resource is less than or equal to a first value. The first value is used to indicate the maximum value of the time domain interval allowed between the first time domain resource and the second time domain resource. Whether the difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value is determined only when the time domain interval between the second time domain resource and the first time domain resource is less than or equal to the first value.

[0127] In some embodiments, the first value is agreed upon by a communication protocol, or the first value is configured by a network device.

[0128] For example, as shown in FIG5 , assume that the first time domain resource 11 is a time domain resource occupying symbols 10 to 13, and the second time domain resource 12 includes the four time domain units preceding the first time domain resource. For example, the second time domain resource 12 is a time domain resource occupying symbols 4 to 7. The time domain interval between the first time domain resource 11 and the second time domain resource 12 is two symbols (symbols 8 and 9). Assuming the first value is three symbols, the time domain interval between the second time domain resource 12 and the first time domain resource 11 is smaller than the first value.

[0129] In some embodiments, the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to a second value. The second value is used to indicate the maximum value of the time domain interval allowed between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal. Only when the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to the second value is it determined whether the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value.

[0130] In an embodiment of the present application, by limiting the maximum time domain interval between the second time domain resources and the first time domain resources, or limiting the maximum time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal, it is possible to ensure that the correlation between the first measurement information and the second measurement information is relatively large, thereby being able to determine that the second measurement information is valid, thereby avoiding the terminal device from storing invalid information for a long time.

[0131] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0132] Condition 2: The difference between the first measurement information and the second measurement information is within a first difference range.

[0133] In some embodiments, the first difference range is agreed upon by a communication protocol, or the first difference range is configured by a network device.

[0134] For example, assuming that the first measurement information is 80dB, the second measurement information is 78dB, and the first difference range is 0dB~3dB, the difference between the first measurement information and the second measurement information is 2dB. Since 2dB is within 0dB~3dB, it is judged that the first condition is met.

[0135] For example, assuming that the first measurement information is 80dB, the second measurement information is 70dB, and the first difference range is 0dB~3dB, then the difference between the first measurement information and the second measurement information is 10dB. Since 10dB is not within 0dB~3dB, it is judged that the first condition is not met.

[0136] In some embodiments, assuming that the first measurement information is CQI, the CQI result is indicated by a CQI index value (index). In some embodiments, the CQI index value (index) corresponds to the MCS index value (index) based on the modulation order.

[0137] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 3, and the first difference range is 2, then the difference between the first measurement information and the second measurement information is 1. Since 1 is within the first difference range, it is judged that the first condition is met.

[0138] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 5, and the first difference range is 2, then the difference between the first measurement information and the second measurement information is 3. Since 3 is not within the first difference range, it is judged that the first condition is not met.

[0139] In some embodiments, assuming that the first measurement information is PMI, the result of the PMI is indicated by a precoding matrix index value (index).

[0140] In some embodiments, the first difference range indicates a permissible range of differences between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is within the first difference range, the first measurement information and the second measurement information are not significantly different. If the difference between the first measurement information and the second measurement information is not within the first difference range, the first measurement information and the second measurement information are significantly different.

[0141] For details, please refer to the embodiment corresponding to the above condition 1.

[0142] In an embodiment of the present application, when the difference between the first measurement information and the second measurement information is within a first difference range, it can be determined that the first measurement information and the second measurement information are not much different, and therefore the first measurement information may not be sent, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption of the terminal device when sending the first measurement information.

[0143] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple items. Based on the embodiment shown in FIG2 , the above step 220 can be replaced by the following sub-steps:

[0144] Step 221: When one piece of first measurement information among multiple pieces of first measurement information meets a first condition, do not measure the first measurement information, and / or do not send the first measurement information.

[0145] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the i-th piece of first measurement information among the n pieces of first measurement information satisfies a first condition, the i-th piece of first measurement information is not measured and / or the i-th piece of first measurement information is not sent. The value of i is an integer greater than 0 and less than or equal to n.

[0146] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the first condition, the CQI is not measured and / or is not sent.

[0147] In some embodiments, the plurality of first measurement information have different priorities. For example, assuming that the plurality of first measurement information includes CQI and PMI, the priority of PMI is higher than that of CQI.

[0148] In some embodiments, the first measurement information is information that satisfies the first condition and has the highest priority among multiple measurement information. That is, the i-th first measurement information is information that satisfies the first condition and has the highest priority among multiple measurement information.

[0149] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0150] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information meets the first condition, the first measurement information with the highest priority is the above-mentioned one first measurement information.

[0151] In some embodiments, when first measurement information with the highest priority among multiple first measurement information satisfies the first condition, the first measurement information with the highest priority is not measured, and / or the first measurement information with the highest priority is not sent.

[0152] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the first condition, PMI is not measured and / or PMI is not sent.

[0153] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information satisfies the first condition, it is further determined whether the first measurement information with the second highest priority among the multiple first measurement information satisfies the first condition.

[0154] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information does not meet the first condition, it is determined whether the first measurement information with the second highest priority among the multiple first measurement information meets the first condition.

[0155] If the first measurement information of the second-highest priority satisfies the first condition, the first measurement information of the second-highest priority is not measured and / or the first measurement information of the second-highest priority is not sent. If the first measurement information of the second-highest priority does not satisfy the first condition, the first measurement information of the second-highest priority is measured and / or the first measurement information of the second-highest priority is sent. Exemplarily, assuming that the multiple first measurement information include CQI and PMI, the priority of PMI is higher than the priority of CQI. That is, if the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI does not satisfy the first condition, the PMI is measured and / or the PMI is sent.

[0156] Similarly, each piece of first measurement information is judged in sequence according to the priority of the plurality of first measurement information until the first measurement information with the lowest priority is judged.

[0157] It will be appreciated that in the embodiment described in step 221, each piece of first measurement information is judged based on each piece of first measurement information in the plurality of first measurement information. By judging each piece of first measurement information in the plurality of first measurement information, and thereby determining whether to measure and / or send each piece of first measurement information, it is advantageous to make a judgment for each piece of first measurement information, thereby more meticulously reducing the power consumption of the terminal device.

[0158] Based on the embodiment shown in FIG. 2 , step 220 may be replaced by the following sub-steps:

[0159] Step 222: When one piece of first measurement information among the multiple pieces of first measurement information meets the first condition, the multiple pieces of first measurement information are not measured, and / or the multiple pieces of first measurement information are not sent.

[0160] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the kth piece of first measurement information among the n pieces of first measurement information meets the first condition, not all n pieces of first measurement information are measured, and / or not all n pieces of first measurement information are sent. The value of k is an integer greater than 0 and less than or equal to n.

[0161] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the first condition, the CQI and PMI are not measured and / or are not sent.

[0162] In some embodiments, the plurality of first measurement information have different priorities.

[0163] In some embodiments, the first measurement information is information that satisfies the first condition and has the highest priority among the multiple measurement information. That is, the kth first measurement information is information that satisfies the first condition and has the highest priority among the multiple measurement information.

[0164] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0165] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information satisfies the first condition, the first measurement information with the highest priority is the above-mentioned one piece of first measurement information.

[0166] In some embodiments, when first measurement information with the highest priority among multiple first measurement information satisfies a first condition, the multiple first measurement information are not measured and / or the multiple first measurement information are not sent.

[0167] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the first condition, CQI and PMI are not measured and / or CQI and PMI are not sent.

[0168] It should be understood that in an embodiment of the present application, when the first measurement information with the highest priority among multiple first measurement information meets the first condition, it is no longer necessary to determine whether other first measurement information among the multiple first measurement information meet the first condition.

[0169] In some embodiments, if the first measurement information with the highest priority among multiple pieces of first measurement information does not meet the first condition, then the first measurement information with the second highest priority among the multiple pieces of first measurement information is determined to meet the first condition. If the first measurement information with the second highest priority among the multiple pieces of first measurement information meets the first condition, then further determination of whether other pieces of first measurement information meet the first condition is discontinued. This process is analogous and not further detailed here.

[0170] If the first measurement information with the second highest priority meets the first condition, the multiple first measurement information are not measured and / or the multiple first measurement information are not sent. If the first measurement information with the second highest priority does not meet the first condition, the first measurement information with the third priority among the multiple first measurement information is further determined to determine whether it meets the first condition.

[0171] In an embodiment of the present application, by judging one first measurement information among multiple first measurement information, it is determined whether to measure and / or send each first measurement information, which is beneficial to reducing the power consumption required for the terminal device to judge each first measurement information. The terminal device only needs to judge that there is one first measurement information that meets the first condition, thereby being able to reduce the power consumption of the terminal device to a greater extent.

[0172] Based on the embodiment shown in FIG. 2 , step 220 may be replaced by the following sub-steps:

[0173] Step 223: When each piece of first measurement information in the plurality of first measurement information satisfies the first condition, the plurality of first measurement information is not measured, and / or the plurality of first measurement information is not sent.

[0174] In some embodiments, when at least one first measurement information among the multiple first measurement information does not satisfy the first condition, the multiple first measurement information are measured and / or the multiple first measurement information are sent.

[0175] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer, if each piece of the n first measurement information satisfies a first condition, not all n pieces of the first measurement information are measured, and / or not all of the n pieces of the first measurement information are sent.

[0176] Exemplarily, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes CQI and PMI, if both CQI and PMI meet the first condition, CQI and PMI are not measured and / or are not sent.

[0177] In some embodiments, the plurality of first measurement information have different priorities.

[0178] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0179] In some embodiments, based on the priority of each piece of first measurement information among the plurality of first measurement information, each piece of first measurement information is sequentially determined to determine whether it satisfies the first condition. If the first measurement information corresponding to the tth priority does not satisfy the first condition, the plurality of first measurement information is measured and / or sent. The remaining first measurement information is not further determined.

[0180] For example, assuming that the first measurement information preconfigured for transmission on the first time domain resource includes CQI, PMI, and RSRP. The priority of PMI is higher than the priority of CQI, which in turn is higher than the priority of RSRP. First, whether the PMI satisfies the first condition is determined. If the PMI satisfies the first condition, the CQI is determined to satisfy the first condition. If the CQI satisfies the first condition, the RSRP is determined to satisfy the first condition. If the PMI satisfies the first condition, the CQI satisfies the first condition, and the RSRP satisfies the first condition, the CQI, PMI, and RSRP are not measured and / or are not transmitted. If the PMI does not satisfy the first condition, the determination of whether the CQI satisfies the first condition is discontinued, and the CQI, PMI, and RSRP are measured and / or transmitted. If the PMI satisfies the first condition, and the CQI does not satisfy the first condition, the determination of whether the RSRP satisfies the first condition is discontinued, and the CQI, PMI, and RSRP are measured and / or transmitted. When the PMI satisfies the first condition, the CQI satisfies the first condition, and the RSRP does not satisfy the first condition, the CQI, the PMI, and the RSRP are measured, and / or the CQI, the PMI, and the RSRP are sent.

[0181] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0182] Condition three: the first measurement information is less than or equal to the second predetermined value.

[0183] In some embodiments, the second predetermined value is agreed upon by a communication protocol, or the second predetermined value is configured by a network device.

[0184] Exemplarily, assuming that the first measurement information is 45 dB and the second predetermined value is 50 dB, since 45 dB is less than 50 dB, it is determined that the first condition is met.

[0185] Exemplarily, assuming that the first measurement information is 70 dB and the second predetermined value is 50 dB, since 70 dB is greater than 50 dB, it is determined that the first condition is not met.

[0186] In some embodiments, assuming that the first measurement information is CQI, the CQI result is indicated by a CQI index value (index). In some embodiments, the CQI index value (index) corresponds to the MCS index value (index) based on the modulation order.

[0187] Exemplarily, assuming that the first measurement information corresponds to a CQI index value of 2, and the second predetermined value is 5, since 2 is less than 5, it is determined that the first condition is met.

[0188] Exemplarily, assuming that the first measurement information corresponds to a CQI index value of 8, and the second predetermined value is 5, since 8 is greater than 5, it is determined that the first condition is not met.

[0189] In some embodiments, the second predetermined value is used to indicate a minimum value of the first measurement information allowed. If the first measurement information is greater than the second predetermined value, it indicates that the current communication transmission condition is good. If the first measurement information is less than or equal to the second predetermined value, it indicates that the current communication transmission condition is poor.

[0190] In an embodiment of the present application, when the first measurement information is less than or equal to the second predetermined value, it can be determined that the current transmission conditions are poor and it is meaningless to send the first measurement information. Therefore, the first measurement information may not be sent to save power consumption.

[0191] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0192] Condition four: the first measurement information is greater than or equal to a third predetermined value.

[0193] In some embodiments, the third predetermined value is agreed upon by a communication protocol, or the third predetermined value is configured by a network device.

[0194] Exemplarily, assuming that the first measurement information is 90 dB and the third predetermined value is 80 dB, since 90 dB is greater than 80 dB, it is determined that the first condition is met.

[0195] Exemplarily, assuming that the first measurement information is 70 dB and the third predetermined value is 80 dB, since 70 dB is less than 80 dB, it is determined that the first condition is not met.

[0196] In some embodiments, assuming that the first measurement information is CQI, the CQI result is indicated by a CQI index value (index). In some embodiments, the CQI index value (index) corresponds to the MCS index value (index) based on the modulation order.

[0197] Exemplarily, assuming that the first measurement information corresponds to a CQI index value of 15, and the third predetermined value is 12, since 15 is greater than 12, it is determined that the first condition is met.

[0198] Exemplarily, assuming that the first measurement information corresponds to a CQI index value of 8, and the third predetermined value is 12, since 8 is less than 12, it is determined that the first condition is not met.

[0199] In an embodiment of the present application, when the first measurement information is greater than or equal to the third predetermined value, it can be determined that the current transmission conditions are relatively excellent, and the network device and the terminal device can communicate freely. Therefore, the terminal device does not need to inform the network device by sending the first measurement information, thereby saving power consumption.

[0200] In some embodiments, since the measurement information is determined based on the downlink signal sent by the network device to the terminal device, the terminal device can report the current downlink channel status to the network device by sending the measurement information to the network device. In some embodiments, the network device directly sends the downlink channel to the terminal device based on the measurement information reported historically. If the terminal device can correctly receive the downlink channel, it can be considered that the current downlink channel status is good, and the terminal device does not need to measure and / or send measurement information again.

[0201] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0202] Condition 5: During the first time period, the terminal device correctly receives the downlink channel.

[0203] In some embodiments, the first time period is before the first time domain resource.

[0204] In some embodiments, the first time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the first time period includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0205] In some embodiments, the first time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the first time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the first time period includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located.

[0206] In some embodiments, the first time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the first time period includes Q milliseconds before the start position of the first time domain resource. Exemplarily, the first time period includes 5 ms before the first time domain resource.

[0207] In some embodiments, the first time period is agreed upon by a communication protocol, or the first time period is configured by a network device.

[0208] In the embodiment of the present application, by presetting the first time period, it is possible to ensure that the result of the judgment based on condition five is valid.

[0209] In some embodiments, the situation in which the terminal device correctly receives the downlink channel includes:

[0210] All downlink channels received by the terminal device are decoded correctly; or,

[0211] The number of correctly decoded channels among the downlink channels received by the terminal device is greater than or equal to a first number threshold; or,

[0212] The probability that the downlink channel received by the terminal device is correctly decoded is greater than or equal to the probability threshold; or,

[0213] The number of downlink channels received by the terminal device is greater than the second number threshold, and the probability of correct decoding is greater than or equal to the probability threshold; or,

[0214] The number of downlink channels received by the terminal device is greater than the second number threshold, and the number of channels decoded correctly is greater than or equal to the first number threshold.

[0215] In some embodiments, the downlink channel includes one or more of the following: a channel carrying downlink control information; a channel carrying downlink data information.

[0216] In some embodiments, the downlink channel includes a channel that carries dedicated downlink control signaling for the terminal device.

[0217] Optionally, the downlink channel includes a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

[0218] In some embodiments, information is channel-coded and then carried in at least one of the downlink channels for transmission. The information transmitted in the downlink channel is channel-coded, and the terminal device can determine whether the received downlink channel is accurate by decoding.

[0219] In some embodiments, the step of the terminal device determining whether the received downlink channel is correct includes:

[0220] Step 1: Receive a downlink channel in a first time period;

[0221] Step 2: Decode the downlink channel;

[0222] Step 3: Based on the accuracy of downlink channel decoding, determine whether the terminal device correctly receives the downlink channel.

[0223] In some embodiments, if all downlink channels received by the terminal device are decoded correctly, the terminal device is judged to have correctly received the downlink channels. If at least one downlink channel received by the terminal device is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels. For example, assuming that the number of downlink channels received by the terminal device is 10, if all 10 downlink channels are decoded correctly, the terminal device is judged to have correctly received the downlink channels; if at least one downlink channel among the 10 downlink channels is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels.

[0224] In some embodiments, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to a first quantity threshold, it is judged that the terminal device has correctly received the downlink channel. When the number of correctly decoded channels in the downlink channels received by the terminal device is less than the first quantity threshold, it is judged that the terminal device has not correctly received the downlink channel. For example, assuming that the number of downlink channels received by the terminal device is 10 and the first quantity threshold is 8, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to 8, it is judged that the terminal device has correctly received the downlink channel; when the number of correctly decoded channels in the downlink channels received by the terminal device is less than 8, it is judged that the terminal device has not correctly received the downlink channel.

[0225] In some embodiments, the first quantity threshold is agreed upon by a communication protocol, or the first quantity threshold is configured by a network device.

[0226] In some embodiments, if the probability that the downlink channel received by the terminal device is correctly decoded is greater than or equal to a probability threshold, it is determined that the terminal device has correctly received the downlink channel. If the probability that the downlink channel received by the terminal device is correctly decoded is less than the probability threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0227] In some embodiments, the probability threshold is agreed upon by a communication protocol, or the probability threshold is configured by a network device.

[0228] In some embodiments, if the number of downlink channels received by the terminal device is greater than a second number threshold and the probability of correct decoding is greater than or equal to a probability threshold, it is determined that the terminal device has correctly received the downlink channel. If the number of downlink channels received by the terminal device is less than the second number threshold and / or the probability of correct decoding of the received downlink channels is less than the probability threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0229] In some embodiments, the second quantity threshold is agreed upon by a communication protocol, or the second quantity threshold is configured by a network device.

[0230] In some embodiments, if the number of downlink channels received by the terminal device is greater than a second quantity threshold and the number of channels correctly decoded is greater than or equal to a first quantity threshold, it is determined that the terminal device has correctly received the downlink channel. If the number of downlink channels received by the terminal device is less than or equal to the second quantity threshold and / or the number of channels correctly decoded is less than the first quantity threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0231] In some embodiments, the transmission parameters of the downlink channel are determined based on physical layer signaling or dynamic signaling. For example, the transmission parameters of the downlink channel are dynamically determined based on measurement information periodically reported by the terminal device.

[0232] In some embodiments, the transmission parameters of the downlink channel include one or more of the following: number of information bits; time domain resources; frequency domain resources; modulation method; coding method; coding rate; precoding information; and antenna port information.

[0233] In the embodiment of the present application, the correct reception of the downlink channel by the terminal device in the first time period implicitly indicates that the measurement information previously sent by the terminal device is still valid. Therefore, the first measurement information may not be measured and / or sent, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption generated by the terminal device measuring the first measurement, and is also beneficial to reducing the power consumption generated by the terminal device sending the first measurement information.

[0234] In some embodiments, the uplink channel and the downlink channel in some communication systems use the same frequency for transmission, such as in a TDD system. In some embodiments, when the uplink channel and the downlink channel use the same frequency for transmission, and the time interval between the sending moment of the uplink channel and the sending moment of the downlink channel is less than the interval threshold, it can be considered that there is channel reciprocity between the uplink channel and the downlink channel. That is, at this time, the quality of the uplink channel can be regarded as equivalent to the quality of the downlink channel. In this case, the terminal device can send an uplink channel or signal to the network device to let the network device know the current downlink channel situation, without the terminal device having to measure and / or send measurement information again.

[0235] In some embodiments, based on the embodiment shown in FIG. 2 , the first condition includes:

[0236] Condition six: During the second time period, the terminal device sends an uplink channel or signal.

[0237] In some embodiments, the second time period is before the first time domain resource.

[0238] In some embodiments, the second time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time period includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0239] In some embodiments, the second time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the second time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the second time period includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located.

[0240] In some embodiments, the second time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time period includes Q milliseconds before the start position of the first time domain resource. Exemplarily, the second time period includes 5 ms before the first time domain resource.

[0241] In some embodiments, the second time period is agreed upon in a communication protocol, or the second time period is configured by a network device.

[0242] In some embodiments, within the second time period, the terminal device sends an uplink channel or signal, including: within the second time period, the number of times the terminal device sends the uplink channel or signal is greater than a number threshold.

[0243] In some embodiments, the number threshold is agreed upon by a communication protocol, or the number threshold is configured by a network device.

[0244] Exemplarily, assuming that the number threshold is 10 times, if the number of times the terminal device sends the uplink channel or signal is greater than 10 times within the second time period, it is considered that the first condition is met.

[0245] In the embodiment of the present application, a number threshold is set to determine whether the number of times the terminal device sends an uplink channel or signal within the second time period meets the number threshold, so that the judgment result is valid.

[0246] In some embodiments, the uplink channel or signal includes one or more of the following: a channel carrying uplink control information; a channel carrying uplink data information; a random access channel; a channel carrying non-periodic measurement information; a preamble sequence; a reference signal; or a sounding signal.

[0247] In some embodiments, the uplink channel or signal includes a channel carrying uplink control information. For example, the uplink channel or signal includes a physical uplink control channel (PUCCH).

[0248] In some embodiments, the uplink channel or signal includes a channel carrying uplink data information. For example, the uplink channel or signal includes a physical uplink shared channel (PUSCH).

[0249] In some embodiments, the uplink channel or signal includes a random access channel. For example, the uplink channel or signal includes a physical random access channel (PRACH).

[0250] In some embodiments, the uplink channel or signal includes a preamble sequence. For example, the uplink channel or signal includes a Preamble.

[0251] In some embodiments, the uplink channel or signal includes a reference signal. For example, the uplink channel or signal includes a demodulation reference signal (DMRS).

[0252] In some embodiments, the uplink channel or signal includes a sounding signal, for example, an SRS.

[0253] In some embodiments, the uplink channel or signal includes a channel carrying aperiodic measurement information, wherein the aperiodic measurement information is measurement information for a target cell, carrier, or frequency band portion.

[0254] In some embodiments, the non-periodic measurement information is measurement information for the target cell or carrier or frequency band portion, and the non-periodic measurement information includes information of the same type as the first measurement information; wherein the first information is also measurement information for the target cell or carrier or frequency band portion.

[0255] In some embodiments, the transmission bandwidth of the uplink channel or signal is greater than or equal to a bandwidth threshold; and / or the number of resources occupied by the uplink channel or signal in the target frequency domain resources is greater than or equal to a third number threshold.

[0256] In some embodiments, the bandwidth threshold is agreed upon in a communication protocol, or configured by a network device. The wider the transmission bandwidth of the uplink channel or signal, the more effective the determination result of whether the first condition is satisfied by the uplink channel or signal transmitted by the terminal device within the second time period.

[0257] In some embodiments, the third quantity threshold is agreed upon in a communication protocol, or the third quantity threshold is configured by a network device. The more resources the uplink channel or signal occupies, the more effective the result of determining whether the first condition is satisfied by transmitting the uplink channel or signal by the terminal device within the second time period.

[0258] In some embodiments, the target frequency domain resources are at least part of the frequency domain resources in the maximum range of uplink frequency domain resources; or, the target frequency domain resources are at least part of the frequency domain resources in the maximum range of frequency domain resources used to transmit uplink channels or signals.

[0259] In some embodiments, the target frequency domain resource is agreed upon by a communication protocol, or the target frequency domain resource is configured by a network device.

[0260] In some embodiments, condition six applies to TDD cells or carriers.

[0261] In an embodiment of the present application, the terminal device sends an uplink channel or signal within the second time period, which means that the terminal device realizes the function of sending measurement information to the network device by sending the uplink channel or signal. Therefore, the first measurement information may not be measured and / or sent, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption generated by the terminal device measuring the first measurement information, and is also beneficial to reducing the power consumption generated by the terminal device sending the first measurement information.

[0262] In some embodiments, based on the embodiments shown in conditions 1 to 6 above, the first condition further includes:

[0263] Condition seven: The first measurement information and the uplink information do not multiplex transmission resources.

[0264] In some embodiments, the first measurement information and the uplink information do not multiplex transmission resources, including:

[0265] The uplink time domain resource occupied by the uplink channel for transmitting uplink information is different from the first time domain resource; or,

[0266] The uplink time domain resource and the first time domain resource belong to different time units; or,

[0267] The uplink time domain resource does not overlap with the first time domain resource.

[0268] In the embodiment of the present application, the first measurement information and the uplink information do not multiplex transmission resources, which means that the terminal device has achieved the same effect as sending the measurement information by sending the uplink information. Therefore, the first measurement information can be not measured and / or sent, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption of the terminal device.

[0269] FIG7 shows a flow chart of a method for sending measurement information provided by an exemplary embodiment of the present application. The method is executed by a terminal device, and the method further includes:

[0270] Step 320: When the second condition is met, measure first measurement information, and / or send first measurement information; wherein the first measurement information is obtained based on the measurement result of the first signal, and the first measurement information is preconfigured to be sent on the first time domain resource.

[0271] In some embodiments, the first measurement information is obtained by measuring the first signal.

[0272] In some embodiments, the first signal is sent by the network device to the terminal device. For example, the first signal includes a downlink reference signal sent by the network device to the terminal device. By way of example and not limitation, the first signal includes a CSI-RS. Alternatively, the first signal includes a TRS.

[0273] The network device may send the first signal to the terminal device in a periodic or semi-continuous manner.

[0274] In some embodiments, the first signal may be sent by one terminal device to other terminal devices. In this case, the first signal may include an SRS, for example.

[0275] In some embodiments, the first signal is used to measure and obtain first measurement information. For example, a CSI-RS is used to measure and obtain measurement information related to channel state information.

[0276] In some embodiments, the method further includes receiving a first signal. It should be understood that the terminal device receives the first signal before step 220. If the first signal is periodically transmitted by the network device to the terminal device, the terminal device periodically receives the first signal. If the first signal is semi-continuously transmitted by the network device to the terminal device, the terminal device semi-continuously receives the first signal.

[0277] In some embodiments, the first measurement information is preconfigured and sent on a first transmission resource. The first transmission resource includes a first time domain resource and / or a first frequency domain resource. Since the embodiments of the present application primarily relate to the measurement timing of the first signal and / or the transmission timing of the first measurement information, the embodiments of the present application are primarily described using the example of the first measurement information being preconfigured and sent on the first time domain resource.

[0278] In some embodiments, the first transmission resource is a periodic resource or a semi-persistent resource. If the first signal is periodically transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also periodic, then the first transmission resource is also periodic. If the first signal is semi-persistently transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also semi-persistent, then the first transmission resource is also semi-persistent.

[0279] In some embodiments, the first measurement information is carried in a measurement report and sent. The measurement report includes one or more types of measurement information.

[0280] In some embodiments, the first measurement information includes one or more of the following: CQI, PMI, RI, LI, RSRP, RSRQ, SINR, and RSSI. CQI, PMI, RI, and LI can also be understood as channel state information, and RSRP, RSPQ, and SINR can also be understood as interference measurement information.

[0281] In some embodiments, the CQI is used to indicate the quality of the downlink channel. The network device determines appropriate downlink parameters based on the CQI sent by the terminal device. For example, assuming that the CQI value ranges from 0 to 15, a CQI value of 0 indicates the worst downlink channel quality; a CQI value of 15 indicates the best downlink channel quality.

[0282] In some embodiments, the PMI is used to indicate the precoding matrix used by the downlink channel. In some embodiments, the RI is used to indicate the number of valid data streams of the downlink channel. In some embodiments, the LI is used to indicate the number of valid data layers of the downlink channel.

[0283] In some embodiments, RSRP, RSRQ, SINR, and RSSI are all used to indicate the quality of the downlink channel. The values ​​of RSRP, RSRQ, SINR, and RSSI are proportional to the quality of the downlink channel. For example, a larger RSRP value indicates better downlink channel quality; a smaller RSRP value indicates worse downlink channel quality.

[0284] It is worth noting that the first measurement information in the embodiment of the present application can be understood as measurement information to be sent.

[0285] In some embodiments, the first measurement information is represented in numerical form, or in matrix form, or in level form.

[0286] To sum up, the method provided in this embodiment utilizes the second condition to control the terminal device to measure the first measurement information and send the first measurement information when the second condition is met, so that the terminal device does not measure the first measurement information and does not send the first measurement information when the second condition is not met, thereby reducing power consumption.

[0287] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0288] Condition 1: The difference between the first measurement information and the second measurement information is greater than a first predetermined value.

[0289] In some embodiments, the first predetermined value is agreed upon by a communication protocol, or the first predetermined value is configured by a network device.

[0290] For example, assuming that the first measurement information is 80dB, the second measurement information is 78dB, and the first predetermined value is 3dB, the difference between the first measurement information and the second measurement information is 2dB. Since 2dB is less than 3dB, it is determined that the second condition is not met.

[0291] For example, assuming that the first measurement information is 80 dB, the second measurement information is 70 dB, and the first predetermined value is 3 dB, the difference between the first measurement information and the second measurement information is 10 dB. Since 10 dB is greater than 3 dB, it is determined that the second condition is met.

[0292] In some embodiments, assuming that the first measurement information is CQI, the CQI result is indicated by a CQI index value (index). In some embodiments, the CQI index value (index) corresponds to the MCS index value (index) based on the modulation order.

[0293] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 3, and the first predetermined value is 2, then the difference between the first measurement information and the second measurement information is 1. Since 1 is less than 2, it is judged that the second condition is not met.

[0294] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 5, and the first predetermined value is 2, then the difference between the first measurement information and the second measurement information is 3. Since 3 is greater than 2, it is judged that the second condition is met.

[0295] In some embodiments, assuming that the first measurement information is PMI, the result of the PMI is indicated by a precoding matrix index value (index).

[0296] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are the same, it is judged that the second condition is not met; when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are different, it is judged that the second condition is met.

[0297] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1, and the second measurement information also corresponds to a precoding matrix index value of 1, that is, the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are the same, it is judged that the second condition is not met.

[0298] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1 and the second measurement information corresponds to a precoding matrix index value of 2, that is, the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information are different, it is judged that the second condition is met.

[0299] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information both belong to a predetermined index value set, it is judged that the second condition is not met; when the precoding matrix index value corresponding to the first measurement information does not belong to the index value set where the precoding matrix index value corresponding to the second measurement information is located, it is judged that the second condition is met.

[0300] Exemplarily, assuming that the first measurement information corresponds to a precoding matrix index value of 1, the second measurement information also corresponds to a precoding matrix index value of 2, and the predetermined index value set is {1, 2, 5}, then the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information both belong to the predetermined index value set, and therefore, it is determined that the second condition is not met. Alternatively, it can be understood that the precoding matrix index value corresponding to the first measurement information belongs to the index value set in which the precoding matrix index value corresponding to the second measurement information belongs.

[0301] In some embodiments, matrices corresponding to index values ​​in the same index value set are correlated.

[0302] In some embodiments, when the precoding matrix index value corresponding to the first measurement information and the precoding matrix index value corresponding to the second measurement information belong to the same index value set, it is considered that the precoding matrix corresponding to the first measurement information and the precoding matrix corresponding to the second measurement information are correlated.

[0303] For example, assuming that the first measurement information corresponds to a precoding matrix index value of 1, the second measurement information also corresponds to a precoding matrix index value of 2, and the predetermined index value set is {2, 3, 5}, the precoding matrix index value corresponding to the first measurement information does not belong to the index value set where the precoding matrix index value corresponding to the second measurement information is located, and therefore it is judged that the second condition is met.

[0304] In some embodiments, assuming that the first measurement information is RI, the result of RI corresponds to the matrix rank of the precoding matrix.

[0305] In some embodiments, when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information are the same, it is judged that the second condition is not satisfied; when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information are different, it is judged that the second condition is satisfied.

[0306] For example, assuming that the matrix rank corresponding to the first measurement information = 1, and the matrix rank corresponding to the second measurement information = 1, the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information are the same, so it is judged that the second condition is not met.

[0307] For example, assuming that the matrix rank corresponding to the first measurement information is 1 and the matrix rank corresponding to the second measurement information is 2, the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information are different, so it is judged that the second condition is met.

[0308] In some embodiments, when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information both belong to a predetermined rank number set, it is judged that the second condition is not satisfied; when the matrix rank number corresponding to the first measurement information does not belong to the rank number set where the matrix rank number corresponding to the second measurement information belongs, it is judged that the second condition is satisfied.

[0309] For example, assuming that the matrix rank corresponding to the first measurement information is 1, the matrix rank corresponding to the second measurement information is 2, and the predetermined rank set is {1, 2}, then the matrix rank corresponding to the first measurement information and the matrix rank corresponding to the second measurement information both belong to the predetermined rank set, and therefore it is determined that the second condition is not met. Alternatively, it can be understood that the matrix rank corresponding to the first measurement information belongs to the rank set in which the matrix rank corresponding to the second measurement information belongs.

[0310] In some embodiments, matrices corresponding to matrix ranks in the same rank number set are correlated.

[0311] In some embodiments, when the matrix rank number corresponding to the first measurement information and the matrix rank number corresponding to the second measurement information belong to the same rank number set, it is considered that the matrix corresponding to the first measurement information and the matrix corresponding to the second measurement information are correlated.

[0312] For example, assuming that the matrix rank corresponding to the first measurement information = 1, the matrix rank corresponding to the second measurement information = 2, and the predetermined rank set is {2, 3}, the matrix rank corresponding to the first measurement information does not belong to the rank set where the matrix rank corresponding to the second measurement information is located, and therefore it is judged that the second condition is met.

[0313] In some embodiments, the first predetermined value indicates the maximum allowable difference between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value, the difference between the first measurement information and the second measurement information is not significant. If the difference between the first measurement information and the second measurement information is greater than the first predetermined value, the difference between the first measurement information and the second measurement information is significant.

[0314] In an embodiment of the present application, if the difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value, it can be determined that the first measurement information and the second measurement information are not significantly different, and therefore the first measurement information may not be sent, thereby avoiding invalid uplink transmission and facilitating reduced power consumption of the terminal device. If the difference between the first measurement information and the second measurement information is greater than the first predetermined value, it can be determined that the first measurement information and the second measurement information are significantly different, and therefore the first measurement information is sent.

[0315] In some embodiments, the second measurement information is obtained by measuring the second signal.

[0316] In some embodiments, the second signal is sent by the network device to the terminal device. For example, the second signal includes a downlink reference signal sent by the network device to the terminal device. By way of example and not limitation, the second signal includes a CSI-RS. Alternatively, the second signal includes a TRS.

[0317] The network device may send the second signal to the terminal device in a periodic or semi-continuous manner.

[0318] In some embodiments, the second signal may be sent by one terminal device to other terminal devices. In this case, the second signal may include an SRS, for example.

[0319] In some embodiments, the second measurement information is sent on a second transmission resource. The second transmission resource includes a second time domain resource and / or a second frequency domain resource. In the embodiments of the present application, the second measurement information is sent on the second time domain resource as an example.

[0320] In some embodiments, the second measurement information is carried in a measurement report and sent. The second measurement information includes one or more of the following: CQI, PMI, RI, LI, RSRP, RSRQ, SINR, and RSSI.

[0321] In some embodiments, the second measurement information is represented in numerical form, or in matrix form, or in level form.

[0322] In some embodiments, the second measurement information and the first measurement information are of the same type of information. Exemplarily, both the first measurement information and the second measurement information are CQIs.

[0323] In some embodiments, the second measurement information corresponds to the same representation as the first measurement information.

[0324] In some embodiments, when multiple first measurement information are preconfigured to be sent on the first time domain resource, the second measurement information is also a plurality of second measurement information corresponding to each piece of the multiple first measurement information. Exemplarily, assuming that the multiple first measurement information includes CQI, PMI, and RI, the second measurement information is also the corresponding CQI, PMI, and RI.

[0325] In some embodiments, the second measurement information is information of the same type as the first measurement information that is sent by the terminal device for the last time before the first time domain resource.

[0326] In some embodiments, only one type of first measurement information is preconfigured for transmission on the first time domain resource. For example, as shown in FIG3 , assume that the first measurement information is a CQI to be reported at time t2, and a PMI was reported at time t1, prior to time t2. Although time t1 is closest to time t2, no CQI was reported at time t1, so the PMI reported at time t1 is not the second measurement information. However, at time t0, prior to time t1, RI, PMI, and CQI, including the CQI, were reported, so the CQI reported at time t0 is considered the second measurement information.

[0327] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple types. For example, as shown in Figure 4, it is assumed that three types of first measurement information are to be reported at time t2, namely RI, PMI and CQI. CQI was reported at time t1 before time t2, so it is considered that the CQI reported at time t1 is the second measurement information corresponding to the CQI to be reported at time t2. PMI was reported at time t0 before time t1, so it is considered that the PMI reported at time t0 is the second measurement information corresponding to the PMI to be reported at time t2. However, there is no second measurement information corresponding to the RI to be reported at time t2 within the preset time period. In some embodiments, the second measurement information is measurement information within a preset time period, and the preset time period includes the second time domain resource.

[0328] It is worth noting that the second measurement information in the embodiment of the present application can be understood as the measurement information that has been sent.

[0329] In some embodiments, the second time domain resource for sending the second measurement information is before the first time domain resource.

[0330] In some embodiments, the second time domain resource includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time domain resource includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiment of the present application includes at least one of a subframe, a time slot, and a symbol. For example, as shown in Figure 5, it is assumed that the first time domain resource 11 is a time domain resource occupying symbol 10 to symbol 13, and the second time domain resource 12 includes 4 time domain units preceding the first time domain resource. For example, the second time domain resource 12 is a time domain resource occupying symbol 4 to symbol 7.

[0331] In some embodiments, the second time domain resource includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the second time domain resource includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the second time domain resource includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located. Exemplarily, as shown in FIG6 , assuming that the time domain unit where the first time domain resource 11 is located is the 4th time slot, the second time domain resource 12 includes 2 time slots preceding the time slot where the first time domain resource 11 is located. For example, the second time domain resource 12 includes the 1st time slot and the 2nd time slot.

[0332] In some embodiments, the second time domain resource includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time domain resource includes Q milliseconds before the starting position of the first time domain resource. Exemplarily, the second time domain resource includes 5 ms before the first time domain resource.

[0333] In some embodiments, the second time domain resource is a resource that is most recently used to send the second measurement information before the first time domain resource.

[0334] In some embodiments, there is only one type of first measurement information preconfigured to be sent on the first time domain resource. For example, as shown in FIG3 , the first time domain resource is the time domain resource corresponding to time t2, and the second time domain resource is the time domain resource corresponding to time t0.

[0335] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple types. Exemplarily, as shown in FIG4 , the first time domain resource corresponding to each first measurement information is the time domain resource corresponding to time t2, the second time domain resource corresponding to the CQI is the time domain resource corresponding to time t1, and the second time domain resource corresponding to the PMI is the time domain resource corresponding to time t0.

[0336] In some embodiments, the first time domain resource and the second time domain resource are adjacent time domain resources, or the first time domain resource and the second time domain resource are non-adjacent time domain resources.

[0337] In some embodiments, the time domain resource lengths corresponding to the first time domain resource and the second time domain resource are the same. For example, the first time domain resource and the second time domain resource are both time domain resources including 4 symbols.

[0338] In some embodiments, the time domain resource lengths corresponding to the first time domain resource and the second time domain resource are different. For example, the first time domain resource is a time domain resource including 3 symbols, and the second time domain resource is a time domain resource including 4 symbols.

[0339] In some embodiments, a time domain interval between the second time domain resource and the first time domain resource is less than or equal to a first value. The first value is used to indicate a maximum value of the time domain interval allowed between the first time domain resource and the second time domain resource. Whether the difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value is determined only when the time domain interval between the second time domain resource and the first time domain resource is less than or equal to the first value.

[0340] In some embodiments, the first value is agreed upon by a communication protocol, or the first value is configured by a network device.

[0341] For example, as shown in FIG5 , assume that the first time domain resource 11 is a time domain resource occupying symbols 10 to 13, and the second time domain resource 12 includes the four time domain units preceding the first time domain resource. For example, the second time domain resource 12 is a time domain resource occupying symbols 4 to 7. The time domain interval between the first time domain resource 11 and the second time domain resource 12 is two symbols (symbols 8 and 9). Assuming the first value is three symbols, the time domain interval between the second time domain resource 12 and the first time domain resource 11 is smaller than the first value.

[0342] In some embodiments, the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to a second value. The second value is used to indicate the maximum value of the time domain interval allowed between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal. Only when the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to the second value is it determined whether the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value.

[0343] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0344] Condition 2: The difference between the first measurement information and the second measurement information is not within the first difference range.

[0345] In some embodiments, the first difference range is agreed upon by a communication protocol, or the first difference range is configured by a network device.

[0346] For example, assuming that the first measurement information is 80dB, the second measurement information is 78dB, and the first difference range is 0dB~3dB, the difference between the first measurement information and the second measurement information is 2dB. Since 2dB is within 0dB~3dB, it is judged that the second condition is not met.

[0347] For example, assuming that the first measurement information is 80dB, the second measurement information is 70dB, and the first difference range is 0dB~3dB, then the difference between the first measurement information and the second measurement information is 10dB. Since 10dB is not within 0dB~3dB, it is judged that the second condition is met.

[0348] In some embodiments, assuming that the first measurement information is CQI, the CQI result is indicated by a CQI index value (index). In some embodiments, the CQI index value (index) corresponds to the MCS index value (index) based on the modulation order.

[0349] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 3, and the first difference range is 2, then the difference between the first measurement information and the second measurement information is 1. Since 1 is within the first difference range, it is judged that the second condition is not met.

[0350] For example, assuming that the first measurement information corresponds to a CQI index value = 2, the second measurement information corresponds to a CQI index value = 5, and the first difference range is 2, then the difference between the first measurement information and the second measurement information is 3. Since 3 is not within the first difference range, it is judged that the second condition is met.

[0351] In some embodiments, the first difference range indicates a permissible range of differences between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is within the first difference range, the first measurement information and the second measurement information are not significantly different. If the difference between the first measurement information and the second measurement information is not within the first difference range, the first measurement information and the second measurement information are significantly different.

[0352] For details, please refer to the embodiment corresponding to the above condition 1.

[0353] In an embodiment of the present application, if the difference between the first measurement information and the second measurement information is within a first difference range, it can be determined that the first measurement information and the second measurement information are not significantly different, and therefore the first measurement information may not be sent, thereby avoiding invalid uplink transmission and facilitating reduced power consumption of the terminal device. If the difference between the first measurement information and the second measurement information is not within the first difference range, it can be determined that the first measurement information and the second measurement information are significantly different, and therefore the first measurement information is sent.

[0354] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple items. Based on the embodiment shown in FIG7 , the above step 320 can be replaced by the following sub-steps:

[0355] Step 321: When one piece of first measurement information among multiple pieces of first measurement information meets the second condition, measure the first measurement information and / or send the first measurement information.

[0356] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the i-th piece of first measurement information among the n pieces of first measurement information satisfies a second condition, the i-th piece of first measurement information is measured and / or the i-th piece of first measurement information is sent. The value of i is an integer greater than 0 and less than or equal to n.

[0357] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the second condition, the CQI is measured and / or sent.

[0358] In some embodiments, the plurality of first measurement information have different priorities. For example, assuming that the plurality of first measurement information includes CQI and PMI, the priority of PMI is higher than that of CQI.

[0359] In some embodiments, the first measurement information is the information that satisfies the second condition and has the highest priority among the multiple measurement information. That is, the i-th first measurement information is the information that satisfies the second condition and has the highest priority among the multiple measurement information.

[0360] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0361] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information satisfies the second condition, the first measurement information with the highest priority is the above-mentioned one first measurement information.

[0362] In some embodiments, when the first measurement information with the highest priority among the plurality of first measurement information meets the second condition, the first measurement information with the highest priority is measured, and / or the first measurement information with the highest priority is sent.

[0363] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the second condition, the PMI is measured and / or the PMI is sent.

[0364] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information meets the second condition, it is further determined whether the first measurement information with the second highest priority among the multiple first measurement information meets the second condition.

[0365] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information does not meet the second condition, it is determined whether the first measurement information with the second highest priority among the multiple first measurement information meets the second condition.

[0366] If the first measurement information of the second highest priority satisfies the second condition, the first measurement information of the second highest priority is measured and / or the first measurement information of the second highest priority is transmitted. If the first measurement information of the second highest priority does not satisfy the second condition, the first measurement information of the second highest priority is measured and / or the first measurement information of the second highest priority is transmitted. Exemplarily, assuming that the multiple first measurement information include CQI and PMI, the priority of PMI is higher than the priority of CQI. That is, if the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI does not satisfy the second condition, the PMI is measured and / or the PMI is transmitted.

[0367] Similarly, each piece of first measurement information is judged in sequence according to the priority of the plurality of first measurement information until the first measurement information with the lowest priority is judged.

[0368] It can be understood that, in the embodiment described in step 321, each first measurement information in the plurality of first measurement information is used as a unit to perform a judgment on each first measurement information.

[0369] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple items. Based on the embodiment shown in FIG7 , the above step 320 can be replaced by the following sub-steps:

[0370] Step 322: When one piece of first measurement information among the multiple pieces of first measurement information meets the second condition, measure the multiple pieces of first measurement information, and / or send the multiple pieces of first measurement information.

[0371] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the kth piece of first measurement information among the n pieces of first measurement information meets the second condition, all n pieces of first measurement information are measured and / or all n pieces of first measurement information are sent. The value of k is an integer greater than 0 and less than or equal to n.

[0372] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the second condition, the CQI and PMI are measured and / or sent.

[0373] In some embodiments, the plurality of first measurement information have different priorities.

[0374] In some embodiments, the first measurement information is information that satisfies the second condition and has the highest priority among the multiple measurement information. That is, the kth first measurement information is information that satisfies the second condition and has the highest priority among the multiple measurement information.

[0375] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0376] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information satisfies the second condition, the first measurement information with the highest priority is the above-mentioned one first measurement information.

[0377] In some embodiments, when first measurement information with the highest priority among multiple first measurement information satisfies the second condition, the multiple first measurement information are measured and / or the multiple first measurement information are sent.

[0378] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if the PMI meets the second condition, the CQI and PMI are measured and / or the CQI and PMI are sent.

[0379] It should be understood that in an embodiment of the present application, when the first measurement information with the highest priority among multiple first measurement information meets the second condition, it is no longer necessary to determine whether other first measurement information among the multiple first measurement information meet the second condition.

[0380] In some embodiments, if the first measurement information with the highest priority among multiple pieces of first measurement information does not meet the second condition, then the first measurement information with the second highest priority among the multiple pieces of first measurement information is determined to meet the second condition. If the first measurement information with the second highest priority among the multiple pieces of first measurement information meets the second condition, then further determination of whether other pieces of first measurement information meet the second condition is discontinued. This process is analogous and not further detailed here.

[0381] If the first measurement information with the second highest priority meets the second condition, multiple pieces of first measurement information are measured and / or multiple pieces of first measurement information are sent. If the first measurement information with the second highest priority does not meet the second condition, further determining whether the first measurement information with the third priority among the multiple pieces of first measurement information meets the second condition.

[0382] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple items. Based on the embodiment shown in FIG7 , the above step 320 can be replaced by the following sub-steps:

[0383] Step 323: When each piece of first measurement information in the multiple pieces of first measurement information satisfies the second condition, measure the multiple pieces of first measurement information, and / or send the multiple pieces of first measurement information.

[0384] In some embodiments, if at least one piece of first measurement information among the multiple pieces of first measurement information does not satisfy the second condition, the multiple pieces of first measurement information are not measured, and / or the multiple pieces of first measurement information are not sent.

[0385] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer, if each piece of the n first measurement information satisfies the second condition, all n pieces of the first measurement information are measured and / or all n pieces of the first measurement information are sent.

[0386] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when both CQI and PMI meet the second condition, the CQI and PMI are measured and / or sent.

[0387] In some embodiments, the plurality of first measurement information have different priorities.

[0388] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0389] In some embodiments, based on the priority of each piece of first measurement information among the plurality of first measurement information, each piece of first measurement information is sequentially determined to determine whether it satisfies the second condition. If the first measurement information corresponding to the tth priority does not satisfy the second condition, the plurality of first measurement information is not measured and / or the plurality of first measurement information is not sent. Furthermore, the remaining first measurement information is not determined.

[0390] Exemplarily, it is assumed that the first measurement information pre-configured to be sent on the first time domain resource includes CQI, PMI, and RSRP. The priority of PMI is greater than the priority of CQI, and the priority of CQI is greater than the priority of RSRP. Whether the PMI satisfies the second condition is first determined. If the PMI satisfies the second condition, whether the CQI satisfies the second condition is further determined. If the CQI satisfies the second condition, whether the RSRP satisfies the second condition is further determined. If the PMI satisfies the second condition, the CQI satisfies the second condition, and the RSRP satisfies the second condition, the CQI, PMI, and RSRP are measured and / or sent. If the PMI does not satisfy the second condition, whether the CQI satisfies the second condition is no longer determined, and the CQI, PMI, and RSRP are not measured and / or sent. If the PMI satisfies the second condition and the CQI does not, the determination of whether the RSRP satisfies the second condition is discontinued, and the CQI, PMI, and RSRP are not measured and / or the CQI, PMI, and RSRP are not sent. If the PMI satisfies the second condition and the CQI satisfies the second condition and the RSRP does not, the CQI, PMI, and RSRP are not measured and / or the CQI, PMI, and RSRP are not sent.

[0391] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0392] Condition three: the time domain interval between the second time domain resource and the first time domain resource is greater than the first value.

[0393] In some embodiments, the first value is agreed upon by a communication protocol, or the first value is configured by a network device.

[0394] In some embodiments, the first value is used to indicate a maximum value of the time domain interval allowed between the first time domain resource and the second time domain resource. If the time domain interval between the second time domain resource and the first time domain resource is greater than the first value, the second condition is determined to be satisfied.

[0395] For details, please refer to the embodiment corresponding to the above condition 1.

[0396] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0397] Condition 4: a time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is greater than a second value.

[0398] In some embodiments, the second value is agreed upon by a communication protocol, or the second value is configured by a network device.

[0399] In some embodiments, the second value is used to indicate a maximum value of a time domain interval allowed between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal. If the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is greater than the second value, the second condition is determined to be satisfied.

[0400] For details, please refer to the embodiment corresponding to the above condition 1.

[0401] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0402] Condition five: the first measurement information is greater than the second predetermined value and less than the third predetermined value.

[0403] In some embodiments, the second predetermined value is agreed upon by a communication protocol, or the second predetermined value is configured by a network device.

[0404] In some embodiments, the third predetermined value is agreed upon by a communication protocol, or the third predetermined value is configured by a network device.

[0405] In this embodiment of the present application, when the first measurement information is greater than the second predetermined value and less than the third predetermined value, it can be determined that the current transmission condition is normal, and the terminal device can inform the network device by sending the first measurement information.

[0406] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0407] Condition six: During the first time period, the terminal device does not correctly receive the downlink channel.

[0408] In some embodiments, the first time period is before the first time domain resource.

[0409] In some embodiments, the first time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the first time period includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0410] In some embodiments, the first time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the first time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the first time period includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located.

[0411] In some embodiments, the first time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the first time period includes Q milliseconds before the start position of the first time domain resource. Exemplarily, the first time period includes 5 ms before the first time domain resource.

[0412] In some embodiments, the first time period is agreed upon by a communication protocol, or the first time period is configured by a network device.

[0413] In some embodiments, the situation where the terminal device fails to correctly receive the downlink channel includes:

[0414] The downlink channel received by the terminal device is not fully decoded correctly; or,

[0415] The number of correctly decoded channels among the downlink channels received by the terminal device is less than a first number threshold; or,

[0416] The probability that the downlink channel received by the terminal device is correctly decoded is less than the probability threshold; or,

[0417] The number of downlink channels received by the terminal device is less than the second number threshold.

[0418] In some embodiments, the downlink channel includes one or more of the following: a channel carrying downlink control information; a channel carrying downlink data information.

[0419] In some embodiments, the downlink channel includes a channel that carries dedicated downlink control signaling for the terminal device.

[0420] Optionally, the downlink channel includes PDCCH or PDSCH.

[0421] In some embodiments, information is channel-coded and then carried in at least one of the downlink channels for transmission. The information transmitted in the downlink channel is channel-coded, and the terminal device can determine whether the received downlink channel is accurate by decoding.

[0422] In some embodiments, the step of the terminal device determining whether the received downlink channel is correct includes:

[0423] Step 1: Receive a downlink channel in a first time period;

[0424] Step 2: Decode the downlink channel;

[0425] Step 3: Based on the accuracy of downlink channel decoding, determine whether the terminal device correctly receives the downlink channel.

[0426] In some embodiments, if all downlink channels received by the terminal device are decoded correctly, the terminal device is judged to have correctly received the downlink channels. If at least one downlink channel received by the terminal device is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels. For example, assuming that the number of downlink channels received by the terminal device is 10, if all 10 downlink channels are decoded correctly, the terminal device is judged to have correctly received the downlink channels; if at least one downlink channel among the 10 downlink channels is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels.

[0427] In some embodiments, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to a first quantity threshold, it is judged that the terminal device has correctly received the downlink channel. When the number of correctly decoded channels in the downlink channels received by the terminal device is less than the first quantity threshold, it is judged that the terminal device has not correctly received the downlink channel. For example, assuming that the number of downlink channels received by the terminal device is 10 and the first quantity threshold is 8, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to 8, it is judged that the terminal device has correctly received the downlink channel; when the number of correctly decoded channels in the downlink channels received by the terminal device is less than 8, it is judged that the terminal device has not correctly received the downlink channel.

[0428] In some embodiments, the first quantity threshold is agreed upon by a communication protocol, or the first quantity threshold is configured by a network device.

[0429] In some embodiments, if the probability that the downlink channel received by the terminal device is correctly decoded is greater than or equal to a probability threshold, it is determined that the terminal device has correctly received the downlink channel. If the probability that the downlink channel received by the terminal device is correctly decoded is less than the probability threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0430] In some embodiments, the probability threshold is agreed upon by a communication protocol, or the probability threshold is configured by a network device.

[0431] In some embodiments, if the number of downlink channels received by the terminal device is greater than a second number threshold and the probability of correct decoding is greater than or equal to a probability threshold, it is determined that the terminal device has correctly received the downlink channel. If the number of downlink channels received by the terminal device is less than the second number threshold and / or the probability of correct decoding of the received downlink channels is less than the probability threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0432] In some embodiments, the second quantity threshold is agreed upon by a communication protocol, or the second quantity threshold is configured by a network device.

[0433] In some embodiments, if the number of downlink channels received by the terminal device is greater than a second quantity threshold and the number of channels correctly decoded is greater than or equal to a first quantity threshold, it is determined that the terminal device has correctly received the downlink channel. If the number of downlink channels received by the terminal device is less than or equal to the second quantity threshold and / or the number of channels correctly decoded is less than the first quantity threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0434] In some embodiments, the transmission parameters of the downlink channel are determined based on physical layer signaling or dynamic signaling. For example, the transmission parameters of the downlink channel are dynamically determined based on measurement information periodically reported by the terminal device.

[0435] In some embodiments, the transmission parameters of the downlink channel include one or more of the following: number of information bits; time domain resources; frequency domain resources; modulation method; coding method; coding rate; precoding information; and antenna port information.

[0436] In this embodiment of the present application, the correct reception of the downlink channel by the terminal device in the first time period implicitly indicates that the measurement information previously sent by the terminal device is still valid. Therefore, it is possible not to measure and / or send the first measurement information, thereby avoiding invalid uplink transmission, which is beneficial to reducing the power consumption of the terminal device. The failure of the terminal device to correctly receive the downlink channel in the first time period implicitly indicates that the measurement information previously sent by the terminal device is no longer valid. Therefore, it is necessary to measure and / or send the first measurement information.

[0437] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0438] Condition seven: During the second time period, the terminal device does not send an uplink channel or signal.

[0439] In some embodiments, the second time period is before the first time domain resource.

[0440] In some embodiments, the second time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time period includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0441] In some embodiments, the second time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the second time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the second time period includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located.

[0442] In some embodiments, the second time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time period includes Q milliseconds before the start position of the first time domain resource. Exemplarily, the second time period includes 5 ms before the first time domain resource.

[0443] In some embodiments, the second time period is agreed upon in a communication protocol, or the second time period is configured by a network device.

[0444] In some embodiments, the uplink channel or signal includes one or more of the following: a channel carrying uplink control information; a channel carrying uplink data information; a random access channel; a channel carrying non-periodic measurement information; a preamble sequence; a reference signal; or a sounding signal.

[0445] In some embodiments, the uplink channel or signal includes a channel carrying uplink control information, for example, the uplink channel or signal includes a PUCCH.

[0446] In some embodiments, the uplink channel or signal includes a channel carrying uplink data information. For example, the uplink channel or signal includes a PUSCH.

[0447] In some embodiments, the uplink channel or signal includes a random access channel, for example, the uplink channel or signal includes a PRACH.

[0448] In some embodiments, the uplink channel or signal includes a preamble sequence. For example, the uplink channel or signal includes a Preamble.

[0449] In some embodiments, the uplink channel or signal includes a reference signal, for example, a DMRS.

[0450] In some embodiments, the uplink channel or signal includes a sounding signal, for example, an SRS.

[0451] In some embodiments, the uplink channel or signal includes a channel carrying aperiodic measurement information, wherein the aperiodic measurement information is measurement information for a target cell, carrier, or frequency band portion.

[0452] In some embodiments, the non-periodic measurement information is measurement information for the target cell or carrier or frequency band portion, and the non-periodic measurement information includes information of the same type as the first measurement information; wherein the first information is also measurement information for the target cell or carrier or frequency band portion.

[0453] In some embodiments, the transmission bandwidth of the uplink channel or signal is greater than or equal to a bandwidth threshold; and / or the number of resources occupied by the uplink channel or signal in the target frequency domain resources is greater than or equal to a third number threshold.

[0454] In some embodiments, the bandwidth threshold is agreed upon in a communication protocol, or configured by a network device. The wider the transmission bandwidth of the uplink channel or signal, the more effective the determination result of whether the first condition is satisfied by the uplink channel or signal transmitted by the terminal device within the second time period.

[0455] In some embodiments, the third quantity threshold is agreed upon in a communication protocol, or the third quantity threshold is configured by a network device. The more resources the uplink channel or signal occupies, the more effective the result of determining whether the first condition is satisfied by transmitting the uplink channel or signal by the terminal device within the second time period.

[0456] In some embodiments, the target frequency domain resources are at least part of the frequency domain resources in the maximum range of uplink frequency domain resources; or, the target frequency domain resources are at least part of the frequency domain resources in the maximum range of frequency domain resources used to transmit uplink channels or signals.

[0457] In some embodiments, the target frequency domain resource is agreed upon by a communication protocol, or the target frequency domain resource is configured by a network device.

[0458] In some embodiments, condition seven applies to TDD cells or carriers.

[0459] In this embodiment of the present application, if the terminal device does not send an uplink channel or signal within the second time period, it means that the terminal device does not send measurement information to the network device by sending an uplink channel or signal, and therefore it is necessary to measure and / or send the first measurement information.

[0460] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0461] Condition eight: During the second time period, the number of times the terminal device sends an uplink channel or signal is less than or equal to the number threshold.

[0462] In some embodiments, the number threshold is agreed upon in a communication protocol, or the number threshold is configured by a network device. For example, assuming the number threshold is 10 times, then within the second time period, if the number of times the terminal device sends an uplink channel or signal is less than or equal to 10 times, the second condition is considered to be met.

[0463] For details, please refer to the embodiment corresponding to the above condition seven.

[0464] In the embodiment of the present application, a number threshold is set to determine whether the number of times the terminal device sends an uplink channel or signal within the second time period meets the number threshold, so that the judgment result is valid.

[0465] In some embodiments, based on the embodiment shown in FIG. 7 , the second condition includes:

[0466] Condition nine: The first measurement information and uplink information use the same transmission resources.

[0467] In some embodiments, the first measurement information and uplink information are multiplexed in transmission resources, including:

[0468] The uplink time domain resources occupied by the uplink channel for transmitting uplink information include at least part of the time domain resources in the first time domain resources; or,

[0469] The uplink time domain resource and the first time domain resource belong to the same time unit; or,

[0470] The uplink time domain resource overlaps with the first time domain resource.

[0471] In this embodiment of the present application, when the first measurement information and uplink information are multiplexed on transmission resources, it is possible to avoid blind detection by network devices due to uncertainty about whether the measurement information is transmitted simultaneously with the uplink information, thereby affecting reliability. The terminal device has already consumed its basic power consumption when sending uplink information. The power consumption reduction gain from transmitting less information on this basis is limited. However, multiplexing the measurement information may also avoid the need to specifically enable the radio frequency next time to transmit subsequent measurement results separately.

[0472] FIG8 shows a block diagram of a device for sending measurement information according to an exemplary embodiment of the present application. The device includes:

[0473] The transmission module 810 is used to not measure the first measurement information and / or not send the first measurement information when a first condition is met; wherein the first measurement information is obtained based on the measurement result of the first signal, and the first measurement information is preconfigured to be sent on the first time domain resource.

[0474] In some embodiments, the first measurement information is obtained by measuring the first signal.

[0475] In some embodiments, the first signal is sent by the network device to the terminal device. For example, the first signal includes a downlink reference signal sent by the network device to the terminal device.

[0476] In some embodiments, when the first condition is met, not measuring the first measurement information includes: when the first condition is met, not measuring the first signal to obtain the first measurement information. It should be understood that in this case, the terminal device does not obtain the first measurement information based on the first signal. If the terminal device does not measure the first signal, the first measurement information obtained based on the first signal measurement is not sent to the network device. In other words, the terminal device does not measure the first measurement information and does not send the first measurement information.

[0477] In some embodiments, if the first condition is met, the first measurement information is not sent. It should be understood that, in one possible scenario, the terminal device has obtained the first measurement information based on the first signal measurement, but if the first condition is met, the first measurement information obtained is not sent; in another possible scenario, the terminal device has not obtained the first measurement information based on the first signal measurement, and if the first condition is met, the terminal device does not measure the first measurement information and does not send the first measurement information.

[0478] In some embodiments, the above situations can be divided into the following two types:

[0479] Case 1: the first measurement information has been obtained based on the first signal measurement; then the terminal device does not send the first measurement information if the first condition is met;

[0480] Case 2: The first measurement information is not obtained based on the first signal measurement; then the terminal device does not measure the first measurement information and does not send the first measurement information when the first condition is met; or the terminal device measures the first measurement information but does not send the first measurement information when the first condition is met.

[0481] In some embodiments, the first measurement information is preconfigured and sent on a first transmission resource. The first transmission resource includes a first time domain resource and / or a first frequency domain resource. Since the embodiments of the present application primarily relate to the measurement timing of the first signal and / or the transmission timing of the first measurement information, the embodiments of the present application are primarily described using the example of the first measurement information being preconfigured and sent on the first time domain resource.

[0482] In some embodiments, the first transmission resource is a periodic resource or a semi-persistent resource. If the first signal is periodically transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also periodic, then the first transmission resource is also periodic. If the first signal is semi-persistently transmitted by the network device to the terminal device, and the first measurement information obtained by the terminal device based on the first signal is also semi-persistent, then the first transmission resource is also semi-persistent.

[0483] In some embodiments, the first measurement information is carried in a measurement report and sent. The measurement report includes one or more types of measurement information.

[0484] In some embodiments, the first measurement information includes one or more of the following: CQI, PMI, RI, LI, RSRP, RSRQ, SINR, and RSSI. CQI, PMI, RI, and LI can also be understood as channel state information, and RSRP, RSPQ, and SINR can also be understood as interference measurement information.

[0485] It is worth noting that the first measurement information in the embodiment of the present application can be understood as measurement information to be sent.

[0486] In some embodiments, the first measurement information is represented in numerical form, or in matrix form, or in level form.

[0487] In some embodiments, the first condition includes:

[0488] Condition 1: The difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value.

[0489] In some embodiments, the first predetermined value is agreed upon by a communication protocol, or the first predetermined value is configured by a network device.

[0490] In some embodiments, the first predetermined value indicates the maximum allowable difference between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value, the difference between the first measurement information and the second measurement information is not significant. If the difference between the first measurement information and the second measurement information is greater than the first predetermined value, the difference between the first measurement information and the second measurement information is significant.

[0491] In some embodiments, the second measurement information is obtained by measuring the second signal.

[0492] In some embodiments, the second signal is sent by the network device to the terminal device. For example, the second signal includes a downlink reference signal sent by the network device to the terminal device.

[0493] In some embodiments, the second measurement information is sent on a second transmission resource. The second transmission resource includes a second time domain resource and / or a second frequency domain resource. In the embodiments of the present application, the second measurement information is sent on the second time domain resource as an example.

[0494] In some embodiments, the second measurement information is carried in a measurement report and sent. The second measurement information includes one or more of the following: CQI, PMI, RI, LI, RSRP, RSRQ, SINR, and RSSI.

[0495] In some embodiments, the second measurement information is represented in numerical form, or in matrix form, or in level form.

[0496] In some embodiments, the second measurement information and the first measurement information are of the same type of information. Exemplarily, both the first measurement information and the second measurement information are CQIs.

[0497] In some embodiments, the second measurement information corresponds to the same representation as the first measurement information.

[0498] In some embodiments, when multiple first measurement information are preconfigured to be sent on the first time domain resource, the second measurement information is also a plurality of second measurement information corresponding to each piece of the multiple first measurement information. Exemplarily, assuming that the multiple first measurement information includes CQI, PMI, and RI, the second measurement information is also the corresponding CQI, PMI, and RI.

[0499] In some embodiments, the second measurement information is information of the same type as the first measurement information that is sent by the terminal device for the last time before the first time domain resource.

[0500] In some embodiments, there is only one type of first measurement information pre-configured to be sent on the first time domain resource.

[0501] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes multiple types.

[0502] It is worth noting that the second measurement information in the embodiment of the present application can be understood as the measurement information that has been sent.

[0503] In some embodiments, the second time domain resource for sending the second measurement information is before the first time domain resource.

[0504] In some embodiments, the second time domain resource includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time domain resource includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0505] In some embodiments, the second time domain resource includes M time domain units preceding the time domain unit in which the first time domain resource is located, where M is a positive integer. For example, the second time domain resource includes M time domain units preceding the time domain unit in which the starting position of the first time domain resource is located. For example, the second time domain resource includes M time domain units preceding the time domain unit in which the ending position of the first time domain resource is located.

[0506] In some embodiments, the second time domain resource includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time domain resource includes Q milliseconds before the starting position of the first time domain resource.

[0507] In some embodiments, the second time domain resource is a resource that is most recently used to send the second measurement information before the first time domain resource.

[0508] In some embodiments, the first time domain resource and the second time domain resource are adjacent time domain resources.

[0509] In some embodiments, the first time domain resource and the second time domain resource are non-adjacent time domain resources.

[0510] In some embodiments, the time domain resource lengths corresponding to the first time domain resource and the second time domain resource are the same.

[0511] In some embodiments, the time domain interval between the second time domain resource and the first time domain resource is less than or equal to a first value. The first value is used to indicate the maximum value of the time domain interval allowed between the first time domain resource and the second time domain resource. Whether the difference between the first measurement information and the second measurement information is less than or equal to a first predetermined value is determined only when the time domain interval between the second time domain resource and the first time domain resource is less than or equal to the first value.

[0512] In some embodiments, the first value is agreed upon by a communication protocol, or the first value is configured by a network device.

[0513] In some embodiments, the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to a second value. The second value is used to indicate the maximum value of the time domain interval allowed between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal. Only when the time domain interval between the time domain resources occupied by the first signal and the time domain resources occupied by the second signal is less than or equal to the second value is it determined whether the difference between the first measurement information and the second measurement information is less than or equal to the first predetermined value.

[0514] In some embodiments, the first condition includes:

[0515] Condition 2: The difference between the first measurement information and the second measurement information is within a first difference range.

[0516] In some embodiments, the first difference range is agreed upon by a communication protocol, or the first difference range is configured by a network device.

[0517] In some embodiments, the first difference range indicates a permissible range of differences between the first measurement information and the second measurement information. If the difference between the first measurement information and the second measurement information is within the first difference range, the first measurement information and the second measurement information are not significantly different. If the difference between the first measurement information and the second measurement information is not within the first difference range, the first measurement information and the second measurement information are significantly different.

[0518] For details, please refer to the embodiment corresponding to the above condition 1.

[0519] In some embodiments, the first measurement information pre-configured to be sent on the first time domain resource includes a plurality of items.

[0520] The transmission module 810 is further configured to, when a piece of first measurement information among the multiple pieces of first measurement information meets a first condition, not measure the piece of first measurement information and / or not send the piece of first measurement information.

[0521] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the i-th piece of first measurement information among the n pieces of first measurement information satisfies a first condition, the i-th piece of first measurement information is not measured and / or the i-th piece of first measurement information is not sent. The value of i is an integer greater than 0 and less than or equal to n.

[0522] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the first condition, the CQI is not measured and / or is not sent.

[0523] In some embodiments, the plurality of first measurement information have different priorities. For example, assuming that the plurality of first measurement information includes CQI and PMI, the priority of PMI is higher than that of CQI.

[0524] In some embodiments, the first measurement information is information that satisfies the first condition and has the highest priority among multiple measurement information. That is, the i-th first measurement information is information that satisfies the first condition and has the highest priority among multiple measurement information.

[0525] In some embodiments, the priority order of the plurality of first measurement information includes at least one of the following: RI priority is higher than CQI priority; RI priority is higher than PMI priority; PMI priority is higher than CQI priority; CQI priority is higher than RSRP priority; CQI priority is higher than RSRQ priority; CQI priority is higher than SINR priority; CQI priority is higher than RSSI priority. Exemplarily, the priority order of the plurality of first measurement information is RI / PMI / LI>CQI>RSRP>RSRQ>SINR.

[0526] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information meets the first condition, the first measurement information with the highest priority is the above-mentioned one first measurement information.

[0527] In some embodiments, when first measurement information with the highest priority among multiple first measurement information satisfies the first condition, the first measurement information with the highest priority is not measured, and / or the first measurement information with the highest priority is not sent.

[0528] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the first condition, PMI is not measured and / or PMI is not sent.

[0529] In some embodiments, if the first measurement information with the highest priority among the multiple pieces of first measurement information meets the first condition, the first measurement information with the second highest priority among the multiple pieces of first measurement information is further determined to determine whether it meets the first condition. If the first measurement information with the highest priority among the multiple pieces of first measurement information does not meet the first condition, the first measurement information with the second highest priority among the multiple pieces of first measurement information is determined to determine whether it meets the first condition.

[0530] If the first measurement information of the second-highest priority satisfies the first condition, the first measurement information of the second-highest priority is not measured and / or the first measurement information of the second-highest priority is not sent. If the first measurement information of the second-highest priority does not satisfy the first condition, the first measurement information of the second-highest priority is measured and / or the first measurement information of the second-highest priority is sent. Exemplarily, assuming that the multiple first measurement information include CQI and PMI, the priority of PMI is higher than the priority of CQI. That is, if the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI does not satisfy the first condition, the PMI is measured and / or the PMI is sent.

[0531] Similarly, each piece of first measurement information is judged in sequence according to the priority of the plurality of first measurement information until the first measurement information with the lowest priority is judged.

[0532] The transmission module 810 is further configured to, if one piece of first measurement information among the multiple pieces of first measurement information meets a first condition, not measure the multiple pieces of first measurement information, and / or not send the multiple pieces of first measurement information.

If the kth piece of first measurement information among the n pieces of first measurement information meets the first condition, not all n pieces of first measurement information are measured, and / or not all n pieces of first measurement information are sent. The value of k is an integer greater than 0 and less than or equal to n.

[0534] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the first condition, the CQI and PMI are not measured and / or are not sent.

[0535] In some embodiments, the plurality of first measurement information have different priorities.

[0536] In some embodiments, the first measurement information is information that satisfies the first condition and has the highest priority among the multiple measurement information. That is, the kth first measurement information is information that satisfies the first condition and has the highest priority among the multiple measurement information.

[0537] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information meets the first condition, the first measurement information with the highest priority is the above-mentioned one first measurement information.

[0538] In some embodiments, when first measurement information with the highest priority among multiple first measurement information satisfies a first condition, the multiple first measurement information are not measured and / or the multiple first measurement information are not sent.

[0539] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the first condition, CQI and PMI are not measured and / or CQI and PMI are not sent.

[0540] It should be understood that in an embodiment of the present application, when the first measurement information with the highest priority among multiple first measurement information meets the first condition, it is no longer necessary to determine whether other first measurement information among the multiple first measurement information meet the first condition.

[0541] In some embodiments, if the first measurement information with the highest priority among multiple pieces of first measurement information does not meet the first condition, then the first measurement information with the second highest priority among the multiple pieces of first measurement information is determined to meet the first condition. If the first measurement information with the second highest priority among the multiple pieces of first measurement information meets the first condition, then further determination of whether other pieces of first measurement information meet the first condition is discontinued. This process is analogous and not further detailed here.

[0542] If the first measurement information with the second highest priority meets the first condition, the multiple first measurement information are not measured and / or the multiple first measurement information are not sent. If the first measurement information with the second highest priority does not meet the first condition, the first measurement information with the third priority among the multiple first measurement information is further determined to determine whether it meets the first condition.

[0543] The transmission module 810 is further configured to, when each piece of first measurement information in the plurality of first measurement information satisfies a first condition, not measure the plurality of first measurement information and / or not send the plurality of first measurement information.

[0544] In some embodiments, when at least one first measurement information among the multiple first measurement information does not satisfy the first condition, the multiple first measurement information are measured and / or the multiple first measurement information are sent.

[0545] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer, if each piece of the n first measurement information satisfies a first condition, not all n pieces of the first measurement information are measured, and / or not all of the n pieces of the first measurement information are sent.

[0546] Exemplarily, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes CQI and PMI, if both CQI and PMI meet the first condition, CQI and PMI are not measured and / or are not sent.

[0547] In some embodiments, based on the priority of each piece of first measurement information among the plurality of first measurement information, each piece of first measurement information is sequentially determined to determine whether it satisfies the first condition. If the first measurement information corresponding to the tth priority does not satisfy the first condition, the plurality of first measurement information is measured and / or sent. The remaining first measurement information is not further determined.

[0548] In some embodiments, the first condition includes:

[0549] Condition three: the first measurement information is less than or equal to the second predetermined value.

[0550] In some embodiments, the second predetermined value is agreed upon by a communication protocol, or the second predetermined value is configured by a network device.

[0551] In some embodiments, the second predetermined value is used to indicate a minimum value of the first measurement information allowed. If the first measurement information is greater than the second predetermined value, it indicates that the current communication transmission condition is good. If the first measurement information is less than or equal to the second predetermined value, it indicates that the current communication transmission condition is poor.

[0552] In some embodiments, the first condition includes:

[0553] Condition four: the first measurement information is greater than or equal to a third predetermined value.

[0554] In some embodiments, the third predetermined value is agreed upon by a communication protocol, or the third predetermined value is configured by a network device.

[0555] In some embodiments, the first condition includes:

[0556] Condition 5: During the first time period, the terminal device correctly receives the downlink channel.

[0557] In some embodiments, the first time period is before the first time domain resource.

[0558] In some embodiments, the first time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the first time period includes N time domain units preceding the starting position of the first time domain resource. It should be noted that the time domain unit described in the embodiments of the present application includes at least one of a subframe, a time slot, and a symbol.

[0559] In some embodiments, the first time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the first time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located.

[0560] In some embodiments, the first time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the first time period includes Q milliseconds before the start position of the first time domain resource.

The information transmitted in the downlink channel is channel-coded, and the terminal device can determine whether the received downlink channel is accurate by decoding.

[0572] In some embodiments, if all downlink channels received by the terminal device are decoded correctly, the terminal device is judged to have correctly received the downlink channels. If at least one downlink channel received by the terminal device is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels. For example, assuming that the number of downlink channels received by the terminal device is 10, if all 10 downlink channels are decoded correctly, the terminal device is judged to have correctly received the downlink channels; if at least one downlink channel among the 10 downlink channels is decoded incorrectly, the terminal device is judged to have incorrectly received the downlink channels.

[0573] In some embodiments, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to a first quantity threshold, it is judged that the terminal device has correctly received the downlink channel. When the number of correctly decoded channels in the downlink channels received by the terminal device is less than the first quantity threshold, it is judged that the terminal device has not correctly received the downlink channel. For example, assuming that the number of downlink channels received by the terminal device is 10 and the first quantity threshold is 8, when the number of correctly decoded channels in the downlink channels received by the terminal device is greater than or equal to 8, it is judged that the terminal device has correctly received the downlink channel; when the number of correctly decoded channels in the downlink channels received by the terminal device is less than 8, it is judged that the terminal device has not correctly received the downlink channel.

[0574] In some embodiments, the first quantity threshold is agreed upon by a communication protocol, or the first quantity threshold is configured by a network device.

[0575] In some embodiments, if the probability that the downlink channel received by the terminal device is correctly decoded is greater than or equal to a probability threshold, it is determined that the terminal device has correctly received the downlink channel. If the probability that the downlink channel received by the terminal device is correctly decoded is less than the probability threshold, it is determined that the terminal device has not correctly received the downlink channel.

If the number of downlink channels received by the terminal device is less than the second quantity threshold and / or the probability of correct decoding of the received downlink channels is less than the probability threshold, the terminal device is judged to have incorrectly received the downlink channels. In some embodiments, the second quantity threshold is agreed upon in a communication protocol, or the second quantity threshold is configured by a network device.

[0578] In some embodiments, if the number of downlink channels received by the terminal device is greater than a second quantity threshold and the number of channels correctly decoded is greater than or equal to a first quantity threshold, it is determined that the terminal device has correctly received the downlink channel. If the number of downlink channels received by the terminal device is less than or equal to the second quantity threshold and / or the number of channels correctly decoded is less than the first quantity threshold, it is determined that the terminal device has not correctly received the downlink channel.

[0579] In some embodiments, the transmission parameters of the downlink channel are determined based on physical layer signaling or dynamic signaling. For example, the transmission parameters of the downlink channel are dynamically determined based on measurement information periodically reported by the terminal device.

[0580] In some embodiments, the transmission parameters of the downlink channel include one or more of the following: number of information bits; time domain resources; frequency domain resources; modulation method; coding method; coding rate; precoding information; and antenna port information.

[0581] In some embodiments, the first condition includes:

[0584] In some embodiments, the second time period includes N time domain units preceding the first time domain resource, where N is a positive integer. For example, the second time period includes N time domain units preceding the starting position of the first time domain resource.

[0585] In some embodiments, the second time period includes M time domain units preceding the time domain unit where the first time domain resource is located, where M is a positive integer. For example, the second time period includes M time domain units preceding the time domain unit where the starting position of the first time domain resource is located. For example, the second time period includes M time domain units preceding the time domain unit where the ending position of the first time domain resource is located.

[0586] In some embodiments, the second time period includes Q milliseconds before the first time domain resource, where Q is a positive real number. For example, the second time period includes Q milliseconds before the start position of the first time domain resource.

[0599] In some embodiments, the transmission bandwidth of the uplink channel or signal is greater than or equal to a bandwidth threshold; and / or the number of resources occupied by the uplink channel or signal in the target frequency domain resources is greater than or equal to a third number threshold.

[0600] In some embodiments, the bandwidth threshold is agreed upon in a communication protocol, or configured by a network device. The wider the transmission bandwidth of the uplink channel or signal, the more effective the determination result of whether the first condition is satisfied by the uplink channel or signal transmitted by the terminal device within the second time period.

[0601] In some embodiments, the third quantity threshold is agreed upon in a communication protocol, or the third quantity threshold is configured by a network device. The more resources the uplink channel or signal occupies, the more effective the result of determining whether the first condition is satisfied by transmitting the uplink channel or signal by the terminal device within the second time period.

[0659] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer. If the i-th piece of first measurement information among the n pieces of first measurement information satisfies a second condition, the i-th piece of first measurement information is measured and / or the i-th piece of first measurement information is sent. The value of i is an integer greater than 0 and less than or equal to n.

[0660] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the second condition, the CQI is measured and / or sent.

[0661] In some embodiments, the plurality of first measurement information have different priorities. For example, assuming that the plurality of first measurement information includes CQI and PMI, the priority of PMI is higher than that of CQI.

[0662] In some embodiments, the first measurement information is the information that satisfies the second condition and has the highest priority among the multiple measurement information. That is, the i-th first measurement information is the information that satisfies the second condition and has the highest priority among the multiple measurement information.

[0665] In some embodiments, when the first measurement information with the highest priority among the plurality of first measurement information meets the second condition, the first measurement information with the highest priority is measured, and / or the first measurement information with the highest priority is sent.

[0666] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI meets the second condition, the PMI is measured and / or the PMI is sent.

[0667] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information meets the second condition, it is further determined whether the first measurement information with the second highest priority among the multiple first measurement information meets the second condition.

[0668] In some embodiments, when the first measurement information with the highest priority among the multiple first measurement information does not meet the second condition, it is determined whether the first measurement information with the second highest priority among the multiple first measurement information meets the second condition.

[0669] If the first measurement information of the second highest priority satisfies the second condition, the first measurement information of the second highest priority is measured and / or the first measurement information of the second highest priority is transmitted. If the first measurement information of the second highest priority does not satisfy the second condition, the first measurement information of the second highest priority is measured and / or the first measurement information of the second highest priority is transmitted. Exemplarily, assuming that the multiple first measurement information include CQI and PMI, the priority of PMI is higher than the priority of CQI. That is, if the first measurement information with the highest priority among the multiple first measurement information is PMI, then if PMI does not satisfy the second condition, the PMI is measured and / or the PMI is transmitted.

[0673] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when the CQI satisfies the second condition, the CQI and PMI are measured and / or sent.

[0678] Exemplarily, assuming that the multiple first measurement information include CQI and PMI, and the priority of PMI is higher than the priority of CQI. That is, the first measurement information with the highest priority among the multiple first measurement information is PMI, then if the PMI meets the second condition, the CQI and PMI are measured and / or the CQI and PMI are sent.

[0679] It should be understood that in an embodiment of the present application, when the first measurement information with the highest priority among multiple first measurement information meets the second condition, it is no longer necessary to determine whether other first measurement information among the multiple first measurement information meet the second condition.

[0680] In some embodiments, if the first measurement information with the highest priority among multiple pieces of first measurement information does not meet the second condition, then the first measurement information with the second highest priority among the multiple pieces of first measurement information is determined to meet the second condition. If the first measurement information with the second highest priority among the multiple pieces of first measurement information meets the second condition, then further determination of whether other pieces of first measurement information meet the second condition is discontinued. This process is analogous and not further detailed here.

[0683] In some embodiments, if at least one piece of first measurement information among the multiple pieces of first measurement information does not satisfy the second condition, the multiple pieces of first measurement information are not measured, and / or the multiple pieces of first measurement information are not sent.

[0684] In some embodiments, assuming that the first measurement information preconfigured to be sent on the first time domain resource includes n pieces, where n is a positive integer, if each piece of the n first measurement information satisfies the second condition, all n pieces of the first measurement information are measured and / or all n pieces of the first measurement information are sent.

[0685] Exemplarily, assuming that the first measurement information pre-configured to be sent on the first time domain resource includes CQI and PMI, when both CQI and PMI meet the second condition, the CQI and PMI are measured and / or sent.

[0686] In some embodiments, based on the priority of each piece of first measurement information among the plurality of first measurement information, each piece of first measurement information is sequentially determined to determine whether it satisfies the second condition. If the first measurement information corresponding to the tth priority does not satisfy the second condition, the plurality of first measurement information is not measured and / or the plurality of first measurement information is not sent.
