In this embodiment and subsequent embodiments, only the base station is taken as an example for introduction.

In order to facilitate a better understanding of the solution proposed by the embodiment of this application, the specific process in this embodiment is introduced below. As shown in Figure 1, when the terminal is in an idle state, the terminal and the base station in the method for reporting measurement information The steps to be performed include:

101. The terminal sends a random access preamble to the base station;

In this embodiment, the terminal can receive a system message sent by the base station before performing random access. The system message includes a narrowband reference signal received power (NRSRP) threshold. The terminal can determine a coverage level based on the NRSRP threshold. (coverage enhancement level, CE).

For ease of understanding, the following is introduced with specific examples. It is assumed that the NRSRP threshold includes two NRSRP thresholds, and the two NRSRP thresholds are the first NRSRP threshold and the second NRSRP threshold. Wherein, the second NRSRP threshold may be smaller than the first NRSRP threshold. If the NRSRP measured by the terminal is less than the second NRSRP threshold, the terminal is in coverage level 2; if the NRSRP measured by the terminal is greater than or equal to the second NRSRP threshold and less than the first NRSRP threshold, the terminal is in coverage level 1; if the terminal measures If the NRSRP value is greater than or equal to the first NRSRP threshold, the terminal is at coverage level 0. Generally, terminals closer to the base station can be considered to be at coverage level 0, which can be understood as "normal coverage", and data transmission does not need to be repeated at this time; terminals farther from the base station can be considered to be at coverage level 1, which can be understood as " Edge coverage", the number of repetitions of data transmission at this time may be 8 or 16; the terminal in the basement and other scenes can be considered as coverage level 2, which can be understood as "extended coverage", at this time the number of repetitions of data transmission can reach 32 Times or 64 times, even higher repetition times can be achieved.

The system message may also include NPRACH configuration information, where each coverage level may correspond to one NPRACH configuration information. The configuration information of the NPRACH may specifically include the maximum number of repetitions Rmax of the search space used for random access, the starting position G, and the offset offset. The search space used for random access may also be referred to as the second type of common search space (type 2 common search space, type 2 CSS). For ease of understanding, assume that there are 3 coverage levels, for example, coverage level 0, coverage level 1, and coverage level 2. At this time, coverage level 0 corresponds to a type 2 CSS Rmax, for example, Rmax_CE0; coverage level 1 corresponds to another type 2 CSS Rmax, for example, Rmax_CE1; coverage level 3 also corresponds to a type 2 CSS Rmax, for example, Rmax_CE2. Taking the anchor carrier as an example, the anchor carrier may correspond to the maximum number of repetitions Rmax of 3 different types 2 CSS. For details, please refer to Table 1-1:

Table 1-1

覆盖等级Coverage level	CE2CE2	CE1CE1	CE0CE0
锚点载波Anchor carrier	Rmax_CE2Rmax_CE2	Rmax_CE1Rmax_CE1	Rmax_CE0Rmax_CE0

In this embodiment, after the terminal receives the system message sent by the base station, the terminal can store the system message for subsequent use.

In this embodiment, before the terminal device performs random access, the terminal device can measure the NRSRP value on the anchor carrier. It can be known from the foregoing steps that, according to the NRSRP value measured by the terminal device and the NRSRP threshold value sent by the base station to the terminal, the terminal can determine a coverage level, such as CE0. Then the terminal randomly selects a carrier, such as carrier A. At this time, the terminal can use the NPRACH configuration corresponding to CE0 on carrier A to send the random access preamble, and the terminal can determine the Rmax of type 2 CSS corresponding to CE0 on carrier A. If the terminal fails to access at this coverage level, for example, the number of failures to send preamble exceeds a threshold, the terminal can perform random access at the next coverage level, for example, perform random access on CE1, and the terminal can use CE1 to correspond Type 2 CSS.

In this embodiment, when the terminal has uplink data to transmit or has other requirements, the terminal can randomly select an uplink carrier to send the random access preamble, and then receive the random access response on the corresponding downlink carrier. The terminal may select an anchor carrier as the carrier for receiving the random access response sent by the base station, or select a non-anchor carrier as the carrier for receiving the random access response sent by the base station, which is not specifically limited here. For ease of understanding, as shown in FIG. 2A to FIG. 2D, this embodiment first takes the example in which the terminal selects a non-anchor carrier as the carrier for receiving the random access response sent by the base station. At this time, the terminal will send a random access preamble to the base station on the uplink non-anchor carrier, that is, msg1 shown in FIG. 2A to FIG. 2D.

For ease of introduction, in this embodiment and subsequent embodiments, the non-anchor carrier receiving the random access response is referred to as the downlink non-anchor carrier A used for random access. It should be understood that the downlink non-anchor carrier A used for random access may be any one of the 15 downlink carriers configured in SIB22-NB. Therefore, the carrier selected for random access by the terminal each time may not be The same carrier.

102. The terminal receives a random access response sent by the base station on the first carrier.

In this embodiment, after the terminal sends the random access preamble to the base station, and the terminal has determined to receive the random access response through the downlink non-anchor carrier A used for random access, the base station will The downlink non-anchor carrier A used for random access replies with a random access response to the terminal, and the random access response is also msg2 shown in FIG. 2A to FIG. 2D.

103. The terminal sends downlink channel measurement information of at least two carriers to the base station in message 3 of the random access procedure, where the at least two carriers include the first carrier;

In this embodiment, after the terminal receives the random access response sent by the base station, the terminal can measure the downlink channel measurement information of the downlink non-anchor carrier A used for random access. Of course, the terminal can also report to the base station. The terminal measures the downlink channel measurement information of the downlink non-anchor carrier A used for random access before replying to the random access response, and the details are not limited here. The carrier used for random access may specifically refer to the downlink carrier used for random access, that is, the carrier where msg2 is located.

In addition, the terminal can also measure the downlink channel measurement information of the downlink anchor carrier and the downlink channel measurement information of the downlink non-anchor carrier B used to page the terminal. Specifically, the downlink channel measurement information used to page the terminal The downlink non-anchor carrier B is calculated by the terminal according to the identification information of the terminal. Therefore, the base station can send a paging to the terminal through the downlink non-anchor carrier B used to page the terminal at a specific moment. Call messages to notify the terminal to perform corresponding operations or update related parameters. In addition, since the downlink channel measurement information of the downlink non-anchor carrier B used to page the terminal is determined by the terminal during the paging phase, the terminal may not need to measure the downlink non-anchor carrier B used to page the terminal again. The downlink channel measurement information of the terminal's downlink non-anchor carrier B, therefore, the measurement of the terminal will not be increased. The reason why the terminal measures the anchor carrier is because the terminal in the idle state needs to perform (radio resource measurement, RRM) measurement on the anchor carrier.

Then, when the terminal replies to the base station with msg3, the terminal sends the downlink channel measurement information of at least two carriers to the base station in msg3 of the random access process. The at least two carriers include the first carrier and the first carrier. One carrier is the carrier that receives the random access response, that is, the downlink non-anchor carrier A used for random access in Figures 2A to 2D. Still taking Figures 2A to 2D as an example, the terminal will send at least The downlink channel measurement information of two carriers, where the downlink channel measurement information of the at least two carriers includes the downlink channel measurement information of the downlink non-anchor carrier A used for random access in FIGS. 2A to 2D. In addition, when the terminal is in an idle state, the downlink channel measurement information of the at least two carriers may also include the downlink channel measurement information of the downlink non-anchor carrier B used to page the terminal and the anchor carrier information. Downlink channel measurement information.

It should be understood that, before sending the downlink channel measurement information of at least two carriers to the base station, the terminal may first screen the multiple downlink channel measurement information. For example, the downlink channel measurement information that the terminal has measured and can send is: downlink channel measurement information of the downlink non-anchor carrier A used for random access, and downlink channel measurement information of the downlink non-anchor carrier B used to page the terminal Channel measurement information, and downlink channel measurement information of the anchor carrier. Wherein, when the downlink channel quality of the downlink non-anchor carrier A used for random access and the downlink channel quality of the anchor carrier are much better than the downlink channel quality of the downlink non-anchor carrier B used for paging the terminal , The terminal may only send the downlink channel measurement information of the downlink non-anchor carrier A used for random access and the downlink channel measurement information of the anchor carrier. Similarly, if the downlink channel quality of the downlink non-anchor carrier B used to page the terminal is better than the downlink channel quality of the anchor carrier, it can also only send the downlink of the downlink non-anchor carrier A used for random access. Channel measurement information and downlink channel measurement information of the downlink non-anchor carrier B used to page the terminal.

For ease of understanding, the quality of the downlink channel measurement information can be distinguished by the number of repetitions. For example, the number of repetitions of the downlink non-anchor carrier A used for random access is 8 times, and the number of repetitions of the anchor carrier is 8 times. If the number of repetitions of the downlink non-anchor carrier B used for paging the terminal is 16, it can be determined that the downlink channel quality of the downlink non-anchor carrier A used for random access and the downlink channel quality of the anchor carrier is far Better than the downlink channel quality of the downlink non-anchor carrier B used to page the terminal. The number of repetitions will be described in detail later, and the details will not be repeated here. In addition, other indicators may also reflect the pros and cons of the downlink channel measurement information, for example, the signal-to-noise ratio and the reference signal reception quality RSRQ, etc., which are not specifically limited here.

In addition, it should be noted that when the carrier used for random access is an anchor point carrier, as shown in Figures 3A and 3B, at this time, the msg3 may only contain the downlink channel measurement information and the anchor point carrier. The downlink non-anchor carrier B used to page the terminal.

In addition, the terminal sending to the base station the downlink channel measurement information of the downlink non-anchor carrier used to page the terminal may also include when the base station and the terminal both support the absence of paging messages, and paging occasion (paging occasion, PO) When there is also a narrowband reference signal (NRS) before, the terminal sends the downlink channel measurement information of the downlink non-anchor carrier used to page the terminal to the base station.

In this embodiment, the downlink channel measurement information includes the number of repetitions. The number of repetitions refers to the number of times that the base station repeatedly sends the data to ensure that the data sent to the terminal can be received by the terminal. In this embodiment, it refers to the number of repetitions that the base station recommends to set when receiving data sent by the base station on a certain carrier, obtained by the terminal by measuring a certain carrier. That is, when the base station receives the number of repetitions in the downlink channel measurement information sent by the terminal, the base station can refer to the number of repetitions in the downlink channel measurement information and other information in the downlink channel measurement information, and then the base station Then determine the carrier configured for the terminal and the number of repetitions of sending data on the configured carrier.

More specifically, the number of repetitions is the number of repetitions of the NPDCCH, or the minimum number of repetitions of the NPDCCH, which satisfies when the transmission parameters of the NPDCCH are shown in Table 1-2, or the terminal assumes that the transmission parameters of the NPDCCH sent by the base station are shown in Table 1. At -2, the block error rate (BLER) of the NPDCCH can reach 1%.

Table 1-2

It should be understood that the number of repetitions can be represented by multiple bits. For example, it is represented by 2 bits, "00" means no measurement is performed, "01" means the number of repetitions is 8, "10" means the number of repetitions is 16, and "11" means the number of repetitions is 32. In actual applications, it can be adjusted appropriately according to the specific conditions, and the details are not limited here.

For ease of understanding, the following will introduce specific examples:

Assuming that the downlink non-anchor carrier used to page the terminal is carrier B, when the number of repetitions of the downlink non-anchor carrier B used to page the terminal is reported with 2 bits, the non-anchor carrier B can be The maximum number of repetitions Rmax is for reference, as shown in Table 1-3. Among them, the maximum number of repetitions Rmax may be Rmax of the search space used for paging, that is, Rmax_paging, and this search space may also be called type 1 CSS. For ease of understanding, specific values are listed below for introduction. Assuming that Rmax_paging=64, the number of repetitions of the downlink non-anchor carrier B used to page the terminal measured by the terminal is 32 times. At this time, the terminal may use "10" in determining the downlink channel measurement information to be sent to the base station.

Table 1-3

0101	Rmax_paging/4Rmax_paging/4
1010	Rmax_paging/2Rmax_paging/2
1111	Rmax_pagingRmax_paging

It should also be noted that when the terminal reports the downlink channel measurement information of the anchor carrier, the number of repetitions in the downlink channel measurement information can be based on the maximum number of repetitions of the anchor carrier Rmax. Specifically, the Rmax can be of type 2 CSS Rmax. Since different coverage levels correspond to different type 2 CSS Rmax, there may be 3 Rmax on the anchor carrier, as shown in Table 1-1. Therefore, when the terminal reports the downlink channel measurement information of the anchor carrier, the maximum number of repetitions Rmax can be the second type of public search space corresponding to the coverage level when the random access response is successfully received on the anchor carrier, type 2 Rmax of CSS . Specifically, when the NRSRP measured by the terminal is on CE0, the terminal uses the NPRACH configuration corresponding to CE0 to send the random access preamble. At this time, the terminal uses the type 2 CSS Rmax corresponding to the anchor carrier CE0 as a reference to report the downlink channel quality of the anchor carrier, as shown in Table 1-4.

Table 1-4

0000	没有测量No measurement
0101	Rmax_CE0/4Rmax_CE0/4
1010	Rmax_CE0/2Rmax_CE0/2
1111	Rmax_CE0Rmax_CE0

If the terminal fails to access on CE0, for example, the number of failed preamble sending exceeds a threshold, the terminal can switch to CE1 for random access. At this time, the terminal uses the type 2 CSS Rmax corresponding to the anchor carrier CE1 as a reference to report the number of repetitions in the downlink channel quality of the anchor carrier, as shown in Table 1-5.

Table 1-5

0000	没有测量No measurement
0101	Rmax_CE1/4Rmax_CE1/4
1010	Rmax_CE1/2Rmax_CE1/2
1111	Rmax_CE1Rmax_CE1

In addition, when reporting the downlink channel measurement information of the anchor carrier, the protocol can also stipulate that the type 2 CSS Rmax corresponding to a coverage level is always used as a reference to report, or the terminal can also use the type 1 CSS Rmax of the anchor carrier as a reference. To report, the details are not repeated here.

In addition, if the terminal reports the second carrier in the determined downlink channel measurement information, the number of repetitions in the downlink channel measurement information reported by the terminal can be based on the maximum number of repetitions of the second carrier Rmax, which can be the first carrier. The Rmax of the UE-specific search space (UE-specific search space, USS) on the second carrier is not detailed here.

In some feasible embodiments, the downlink channel measurement information may also include signal-to-noise ratio, reference signal reception quality RSRQ, and other information that can reflect the downlink channel quality of the carrier, which is not specifically limited here. In this embodiment and subsequent embodiments, only the downlink channel measurement information includes the number of repetitions as an example for introduction.

In this embodiment, when the terminal sends downlink channel measurement information of at least two carriers to the base station in msg3 for random access, the terminal can report the downlink channel measurement information of each carrier in the following ways:

(1) Different carrier identification information is set for different carriers, so that the base station can distinguish the downlink channel measurement information corresponding to the different carriers in the msg3. As shown in Table 2, it can be represented by 2 bits. The carrier identification information is 00 to indicate the anchor carrier, the carrier identification information is 01 to indicate the non-anchor carrier used to page the terminal, and the carrier identification information is 10 to indicate the carrier. Non-anchor carrier for random access.

Or, 4 bits are used to distinguish the 15 carriers configured by the system message and the anchor carrier. For the specific identification, please refer to Table 2-1.

In addition, in some feasible embodiments, 1 bit may also be used to indicate an anchor point carrier or a non-anchor point carrier for random access, for example, 0 indicates an anchor point carrier, and 1 indicates a non-anchor point. Carrier, and then use the other 4 bits alone to indicate the non-anchor carrier used to page the terminal.

It should be understood that, in practical applications, the identification method of the carrier identification information may be different from the above identification methods. For example, the anchor carrier is represented by no carrier identification information, and the base station configuration is identified by 1 to 15 characters. Of 15 non-anchor carriers. It should be understood that the correspondence between the carrier identification information and the carrier in Table 2 and Table 2-1 can be changed, and the specific correspondence is not limited here. In this embodiment, other identification methods may also be used, which are not specifically limited here.

A more specific possible implementation is to express the downlink channel measurement information of a carrier in the form of carrier identification information and the number of repetitions, that is {carrier identification information, repetition number}, as shown in Table 2-2, { 00, 01} indicates that the number of repetitions on the anchor carrier is 8. The terminal can report multiple carriers, such as {carrier identification information 1, repetition number 1}, {carrier identification information 2, repetition number 2}, etc.

Table 2-2

载波标识信息Carrier identification information	重复次数repeat times	含义meaning
0000	0101	终端上报锚点载波上的重复次数为8The number of repetitions reported by the terminal on the anchor carrier is 8

Therefore, when the base station receives the downlink channel measurement information, the base station can distinguish different carriers and the number of repetitions corresponding to the carriers.

(2) The downlink channel measurement information does not include carrier identification information, and the order of the number of repetitions in message 3 is used to distinguish the number of repetitions corresponding to different carriers. Taking the downlink channel measurement information of the three carriers reported in the msg3 as an example, the downlink channel measurement information is extended to 6 bits, where every 2 bits corresponds to a carrier, so you can distinguish the corresponding carriers according to the bit position sequence The number of repetitions. For example, the highest 2 bits can represent the number of repetitions corresponding to the anchor carrier, the lowest 2 bits can represent the number of repetitions corresponding to the non-anchor carrier used for random access, and the middle 2 bits can represent the non-anchor used to page the terminal. The number of repetitions corresponding to the anchor carrier. Of course, in practical applications, the number of repetitions corresponding to the carrier indicated by the bit position sequence may be different from the sequence listed above, which is not specifically limited here.

In this embodiment, the above two methods can also be combined. For example, it is agreed that the highest two digits represent the number of repetitions corresponding to the anchor carrier, and the next two digits represent the number of repetitions corresponding to the non-anchor carrier for random access. The bit represents the carrier identifier, and the last two digits represent the number of repetitions of the carrier corresponding to the carrier identifier. The order of the above-mentioned bit positions can also be changed, which is not limited here.

The combined results of the above methods are respectively introduced below:

In a possible implementation, if both the base station and the terminal support the absence of paging and there is also a narrowband downlink reference signal NRS before the paging opportunity PO, at this time, the terminal can send a downlink non-anchor point for random access The downlink channel measurement information of the carrier, the downlink channel measurement information of the anchor carrier, and the downlink channel measurement information of the non-anchor carrier used to page the terminal. Among them, in the agreed report bits, the first X1 bits represent the downlink channel measurement information of the downlink non-anchor carrier used for random access, and the next X2 bits represent the downlink channel measurement information of the anchor carrier. X3 bits represent downlink channel measurement information corresponding to a carrier identifier, and the following X4 bits are carrier identifiers. It should be understood that the carrier identifier may indicate a non-anchor carrier used for paging the terminal, where X1, X2, X3, and X4 are all integers greater than or equal to 1.

The specific reporting method can also be similar to implementation A.

In addition, in another possible implementation manner, if neither the base station nor the terminal supports when there is no paging, and there is also a narrowband downlink reference signal NRS before the paging opportunity PO, at this time, the terminal can send The downlink channel measurement information of the random access downlink non-anchor carrier and the downlink channel measurement information of the anchor carrier. Among the bits agreed to be reported, the first Y1 bits represent the downlink channel measurement information of the downlink non-anchor carrier used for random access, and the Y2 bits immediately after represent the downlink channel measurement information of the anchor carrier.

104. The base station determines, according to the downlink channel measurement information of at least two carriers, at least one of the following: the carrier configured to transmit data to the terminal device, the number of repetitions used to send data to the terminal device, and the number of repetitions used to send signaling to the terminal device ；

In this embodiment, after the base station receives the downlink channel measurement information in msg3 sent by the terminal, the base station will determine at least one of the following according to the downlink channel measurement information of at least two carriers: Carrier, the number of repetitions used to send data to the terminal equipment and the number of repetitions used to send signaling to the terminal equipment.

Specifically, when the base station refers to the downlink channel measurement information sent by the terminal, the base station can directly select a carrier from the carriers involved in the downlink channel measurement information as the carrier configured by the base station for the terminal. For ease of introduction, it is called Configure the carrier, and then determine the number of repetitions corresponding to the configured carrier. To facilitate understanding, take Table 3 as an example for introduction. Assume that after receiving the downlink channel measurement information reported by the terminal, the base station determines the anchor carrier and the non-anchor carrier used to page the terminal after a comprehensive evaluation of the block error rate, resource occupancy, and data importance level. B and the carrier A used for random access, the non-anchor carrier B used for paging the terminal is the most suitable, then the base station determines that the non-anchor carrier B used for paging the terminal is the configured carrier, Then, the base station determines the number of repetitions of sending data on the non-anchor point carrier B used to page the terminal. At this time, the base station will refer to the number of repetitions in the downlink channel measurement information reported by the terminal. Then, the base station can use 32 times as the number of repetitions of data sent on the non-anchor carrier B used to page the terminal, but The base station can also reset the number of repetitions, for example, reset the number of repetitions to 16, to ensure that the terminal can save resources when receiving data sent by the base station.

It should be noted that there is an implementation manner, when the terminal uses the downlink non-anchor carrier A for random access, the downlink non-anchor carrier B for paging the terminal, and the downlink channel of the downlink anchor carrier The measurement information is reported to the base station. However, after the base station refers to the downlink channel measurement information reported by the terminal, if the base station analyzes and finds that the carriers involved in the downlink channel measurement information are not suitable, the base station configures the carrier for the terminal It may not be the carrier involved in the downlink channel measurement information, but the base station may refer to the downlink channel measurement information reported by the terminal to determine the configured carrier.
