Description

Carrier measurement method and terminal device

The present application claims priority to Chinese Patent Application No. 201810055011.8, filed on Jan. 19, 2018, the entire disclosure of which is incorporated herein by reference. .

Technical field

The present application relates to the field of communications, and more specifically, to a method and a terminal device for carrier measurement.

Background technique

A terminal device supporting new radio (NR) standard communication needs to perform cell identification and measurement on a carrier other than the serving carrier. The serving carrier is the carrier where the serving cell accessed by the terminal device is located. The carrier is a carrier that is adjacent to the serving carrier. For example, the terminal device searches for and detects a Synchronization Signal Block (SSB) of the cell on the carrier to acquire a physical cell identifier, timing information, and SSB-based measurement result of the cell.

For each carrier, the network device configures corresponding reference signal configuration information for notifying the terminal device of the period of the reference signal on the carrier. For all carriers that the terminal device needs to detect, the network device configures a uniform measurement interval pattern. The terminal device may perform cell identification or measurement operation on all carriers according to information included in the measurement interval pattern, for example, within a measurement interval included in the measurement interval pattern. At present, for a terminal device, it is necessary to measure all carriers that need to be detected according to the measurement indicators specified by the protocol.

1 is a schematic diagram of a communication system suitable for the method of carrier measurement of the present application. As shown in FIG. 1, the communication system 100 includes a network device 102 that can include multiple antennas, such as

antennas

104, 106, 108, 110, 112, and 114. Additionally, network device 102 may additionally include a transmitter chain and a receiver chain, as will be understood by those of ordinary skill in the art, which may include multiple components related to signal transmission and reception (eg, processor, modulator, multiplexer) , encoder, demultiplexer or antenna, etc.).

Network device 102 can communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it will be appreciated that network device 102 can communicate with any number of terminal devices similar to

terminal device

116 or 122.

Terminal devices

116 and 122 can be, for example, cellular telephones, smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other for communicating over wireless communication system 100. Suitable for equipment.

As shown in FIG. 1, terminal device 116 is in communication with

antennas

112 and 114, wherein

antennas

112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, wherein

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

For example, in an FDD system, for example, the forward link 118 can utilize a different frequency band than that used by the reverse link 120, and the forward link 124 can utilize a different frequency band than that used by the reverse link 126.

As another example, in a TDD system and a full duplex system, forward link 118 and reverse link 120 can use a common frequency band, and forward link 124 and reverse link 126 can use a common frequency band.

Each antenna (or set of antennas consisting of multiple antennas) and/or regions designed for communication is referred to as a sector of network device 102. For example, the antenna group can be designed to communicate with terminal devices in sectors of the network device 102 coverage area. In the process in which network device 102 communicates with

terminal devices

116 and 122 via

forward links

118 and 124, respectively, the transmit antenna of network device 102 may utilize beamforming to improve the signal to noise ratio of

forward links

118 and 124. In addition, when the network device 102 uses beamforming to transmit signals to the randomly dispersed

terminal devices

116 and 122 in the relevant coverage area, the network device 102 uses a single antenna to transmit signals to all of its terminal devices. Mobile devices are subject to less interference.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting device and/or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device can encode the data for transmission. In particular, the wireless communication transmitting device may acquire (eg, generate, receive from other communication devices, or store in memory, etc.) a certain number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be included in a transport block (or multiple transport blocks) of data that may be segmented to produce multiple code blocks.

In addition, the communication system 100 may be a PLMN network or a device-to-device (D2D) network or a machine to machine (M2M) network or other network. FIG. 1 is only a simplified schematic diagram of an example in the network. Other network devices may also be included, which are not shown in FIG.

A terminal device supporting NR system communication needs to perform cell identification and measurement on multiple carriers. It should be understood that these carriers may be either co-frequency carriers or inter-frequency carriers. The service carrier refers to the carrier where the serving cell of the terminal device is located, and may also be referred to as a co-frequency carrier. The terminal device can perform data transmission and reception with the serving cell on the service carrier. The inter-frequency carrier is a carrier other than the serving carrier. The inter-frequency carrier and the co-frequency carrier may belong to the same standard, for example, NR system, LTE system, GSM system, and the like. Of course, the intra-frequency carrier and the inter-frequency carrier may also belong to different standards. The terminal device does not perform data transmission and reception on the inter-frequency carrier, but performs cell search, detection of the synchronization signal block SSB of the cell, and measurement of the reference signal, etc., to acquire the physical cell identifier, timing information, and reference signal based on the inter-frequency cell. Measurement results, etc. The co-frequency carrier may be an intra-frequency carrier defined by an existing protocol. The inter-frequency carrier may be an inter-frequency carrier defined by an existing protocol.

A sync signal block, or a Synchronization Sigal (SS)/physical broadcast channel block (PBCH block), is a signal structure suitable for use in 5G and subsequent communication systems. 2 is a schematic diagram of a possible structure of a sync signal block. As shown in FIG. 2, the sync signal block includes a Primary Synchronization Sigal (PSS), a Secondary Synchronization Signal (SSS), and a physical broadcast channel. (Physical Broadcast Channel, PBCH). The main function of PSS and SSS is to help the user equipment identify the cell and synchronize with the cell. The PBCH contains the most basic system information such as system frame number and intraframe timing information. The successful reception of the synchronization signal block by the user equipment is a prerequisite for its access to the cell.

For each carrier, especially the inter-frequency carrier, the network device configures corresponding reference signal configuration information for notifying the terminal device of the period of measuring or receiving the reference signal on the carrier. Taking the synchronization signal block as an example, the network device configures the SSB Measurement Timing Configuration (SMTC) for the terminal device. The SMTC includes an SMTC period, which is a period in which the terminal device receives or measures the SSB, and the SMTC may further include a position and a length of the SSB receiving window. That is, for different carriers, such as inter-frequency carriers or inter-frequency carriers, the network device configures the SMTC pattern (corresponding to SMTC) accordingly. 3 is a schematic diagram of five SMTC patterns configured for five carriers. Take SSB as an example for explanation. The SMTC pattern may include information such as the SMTC period, the position of the SSB receiving window, and the like. As shown in FIG. 3, for carrier 1, the SMTC period is 20 ms, that is, the time interval between the receiving windows of the two SSBs is 20 ms. For carriers 2 to 5, the SMTC periods are 40 ms, 80 ms, 160 ms, 160 ms, respectively.

It should be understood that FIG. 3 is merely exemplary, just to illustrate the form and inclusion of the SMTC. The SMTC can also be in other forms of expression, for example, in the form of a table. Alternatively, the SMTC may also include other content. The embodiments of the present application are not limited herein.

For a certain terminal device, the network device will detect all or part of the carriers (including the same-frequency carrier and/or the inter-frequency carrier) of the terminal device, or all or part of the carriers in a certain frequency range (including the same-frequency carrier and / or inter-frequency carrier) configure a unified measurement gap pattern (MGP). The MGP may include information such as a Measurement Gap Length (MGL) and a Measurement Gap Repetition Period (MGPR). The terminal device may perform cell identification or measurement operation on a plurality of carriers, etc. according to information included in the measurement interval pattern, for example, in a time period in which the duration is a measurement interval (Measurement Gap). 4 is a schematic diagram of a measurement interval pattern for a five carrier configuration. The synchronization signal block is taken as an example for description. As shown in FIG. 4, the measurement interval repetition period is 40 ms, and for carriers 1 to 5, the SMTC periods are 20 ms, 40 ms, 80 ms, 160 ms, and 160 ms, respectively. This measurement interval pattern is applied to carriers 1 to 5. The terminal device may perform operations such as SSB measurement on carriers 1 to 5 during the time period in which the measurement interval is located (the length of time is the length of the measurement interval). For example, within the measurement interval numbered 1, the reference signals on

carriers

1, 2, and 3 can be measured simultaneously. In the measurement interval labeled 2, the reference signals on

carriers

1, 2 and 4 can be measured simultaneously.

In the standard protocol, some measurement indicators (measurement requirements) need to be defined to standardize the measurement behavior of the terminal equipment, especially in the inter-frequency measurement. For example, the measurement indicator can include a cell identification time. Synchronization signal detection time, reference signal index read time, and the like. The terminal device performs measurement of signals on a plurality of carriers and the like based on these measurement indexes.

Currently, in an LTE system, for a terminal device, all carriers that need to be measured define the same measurement index. However, since the period of the reference signals configured on the respective carriers in the NR is different. The chances that each carrier can be measured are different during the same time period. For example, the description shown in FIG. 3 will be described. The SMTC periods configured for carriers 1 through 5 are different. The SMTC period of carrier 1 is 20 ms, the SMTC period of carrier 5 is 160 ms, and the value of MGPR is 40 ms. In the same period of time, it is assumed that the start positions of the reception windows of carrier 1 and carrier 5 are the same. For example, in the 160 ms period, carrier 1 can obtain 4 measurement opportunities, and carrier 5 can only obtain 1 measurement opportunity. In order to ensure that there are enough measurement opportunities on carriers with large SMTC periods, it will inevitably lead to the definition of a long measurement index. E.g. Very long cell identification time or measurement period, etc. However, long measurement metrics are not conducive to the fast moving performance of the terminal equipment. The performance of the terminal device is deteriorated, which affects the user experience.

In 5G, the measurement of the same-frequency carrier assumes an opportunity for the terminal device to measure at least once in each SMTC period (or each MGPR). It is assumed that the measurement index of the inter-frequency carrier is similar to the above definition. That is, the inter-frequency measurement index is an opportunity for the terminal device to measure at least once in each SMTC period (or each MGPR) for each carrier. Since the inter-frequency carrier needs to be measured on multiple carriers, as shown in FIG. 4, for one terminal device, within one measurement measurement interval (Measurement Gap), multiple carriers may need to be measured at the same time. . For example, at measurement interval 1, the reference signals on

carriers

1, 2, 3 need to be measured simultaneously. That is, the measurement interval available for one carrier conflicts with the measurement interval available for other carriers. If the terminal device does not support simultaneous measurement on two or more carriers, then for each of the

carriers

1, 2, and 3, each SMTC period (or each MGRP is not guaranteed). There are opportunities to make measurements. That is to say, such a measurement index requires the terminal device to meet certain capability requirements, which will increase the cost of the terminal device.

There is no definition of inter-frequency carrier measurement requirements in the existing protocols, and it is impossible to constrain the inter-frequency measurement behavior of the terminal equipment. It affects the performance of the terminal device when performing inter-frequency carrier measurement, which causes the inter-frequency measurement delay of the terminal device to be too long, which affects the normal communication of the terminal device.

Based on the above problem, the embodiment of the present application provides a method for measuring a carrier. For a terminal device, a measurement indicator on the carrier may be defined according to each measurement configuration information related to each carrier that the terminal device needs to measure. Consider the fairness and competitiveness of measurement opportunities for different carriers themselves. On the basis of fully considering the equal opportunity of measurement on each carrier, the measurement delay of the terminal device can also be reduced. At the same time, excessive requirements on the measurement capability of the terminal device are avoided, and the cost of the terminal device is reduced. It ensures that the terminal device can communicate normally. Improve the user experience. It should be understood that the carrier measurement method can also be applied to the same frequency carrier.

The method for carrier measurement provided by the present application is described in detail below with reference to FIG. 5. FIG. 5 is a schematic flowchart of a method 200 for carrier measurement according to an embodiment of the present application. The method 200 can be applied to the scenario shown in FIG. It is also applicable to other communication scenarios, and the embodiments of the present application are not limited herein.

As shown in FIG. 5, the method 200 includes:

S210. The terminal device determines, according to the first measurement configuration information, the second measurement configuration information, and the first parameter of the first carrier, a first measurement requirement on the first carrier, where the second measurement configuration information includes being applied to at least two carriers. The measurement configuration information on the at least two carriers includes the first carrier.

The first parameter is determined according to the first measurement configuration information of the first carrier and the second measurement configuration information, or the first parameter is determined according to the number of valid detection carriers of the terminal device.

S220. The terminal device performs measurement on the first carrier according to the first measurement requirement.

The method for carrier measurement provided by the present application, for each carrier to be measured that needs to be measured by the terminal device, the measurement requirement (measurement index) of the carrier to be measured is based on measurement configuration information on the carrier to be measured (first carrier) A measurement configuration information), carrier measurement configuration information (second measurement configuration information) applicable to the plurality of carriers (including the to-be-measured carrier) that the terminal device needs to detect, and a parameter (first parameter) determination. The first parameter is determined according to the measurement configuration information of the to-be-measured carrier and the second measurement configuration information, and is corresponding to the to-be-measured carrier. Or the first parameter is determined according to the number of valid detection carriers of the terminal device. That is, in the process of determining the measurement requirement of the carrier to be measured, the configuration information of the carrier to be measured and other measurement configuration information related to the carrier to be measured are fully considered. According to the actual situation of each carrier, the corresponding measurement requirements are determined. Differentiate processing for different carriers. The fairness and competitiveness of measurement opportunities for different carriers themselves are considered. On the basis of fully considering the measurement opportunities of each carrier, the measurement delay of the terminal device can also be reduced. At the same time, excessive requirements on the measurement capability of the terminal device are avoided, and the cost of the terminal device is reduced. It ensures that the terminal device can communicate normally. Improve the user experience.

Specifically, in S210, when the terminal device needs to perform measurement on a certain carrier (the first carrier is taken as an example for description), the first measurement requirement of the first carrier needs to be determined first, and the first measurement requirement may be referred to as The first measurement indicator or the like is used to regulate the measurement behavior of the first carrier of the terminal device.

The first measurement requirement is determined according to the first measurement configuration information, the second measurement configuration information, and the first parameter of the first carrier. The first measurement configuration information is measurement configuration information corresponding to the first carrier, and the corresponding first measurement configuration information may be the same or different for different carriers. For example, as shown in FIG. 3 or FIG. 4, the five carriers respectively have first measurement configuration information corresponding to themselves, and the five first measurement configuration information are different. It should be understood that the measurement configuration information corresponding to each of the five carriers may be referred to as the first measurement configuration information, but the content included in the five first measurement configuration information is actually different, or the measurement corresponding to the five carriers respectively. The configuration information can be referred to as different measurement configuration information. The embodiments of the present application are not limited herein. For example, the first measurement configuration information may be an SMTC pattern or the like. The SMTC pattern corresponding to each carrier can be different.

The second measurement configuration information includes configuration information applied to a plurality of carriers (at least two carriers), the plurality of carriers including the first carrier. For example, as shown in FIG. 4, the second measurement configuration information may be a measurement interval pattern applied to carriers 1 to 5, and the first carrier may be any one of carriers 1 to 5. It should be understood that the multiple carriers may be all carriers that the terminal device needs to detect, or all carriers within a certain frequency range. The embodiments of the present application are not limited herein. The first parameter is determined according to the first measurement configuration information of the first carrier and the second measurement configuration information, or the first parameter is determined according to the number of valid detection carriers of the terminal device. The number of valid detection carriers is related to the capabilities of the terminal device. The number of valid detection carriers corresponding to different terminal devices may be the same or different. Moreover, the number of effective monitoring carriers corresponding to each carrier may also be the same or different. That is, in the process of determining the first measurement requirement of the first carrier, various measurement configuration information related to the first carrier is fully considered. It is ensured that differentiating processing is performed for different carriers.

When the first parameter is determined according to the number of valid detection carriers of the terminal device, since the number of valid detection carriers is related to the capability of the terminal device, the number of effective detection carriers corresponding to different terminal devices may be different. Also, for one terminal device, since the requirements for different carriers are different, or in other words, the importance of different carriers to the terminal device is different. Therefore, the number of effective monitoring carriers corresponding to each carrier may be the same or different. For all carriers that need to be measured, the same first parameter (carrier coefficient) is used. Alternatively, it may be a first parameter corresponding to each carrier that needs to be measured. The embodiments of the present application are not limited herein.

In S220, the terminal device performs measurement on the first carrier according to the first measurement requirement. For example, the terminal device performs measurement of the reference signal and the like on the first carrier according to the determined first measurement requirement. The terminal device performs signal measurement according to the measurement requirement corresponding to the carrier to be measured, and can ensure differentiated processing for different carriers. Different carriers can use different measurement requirements, fully considering the fairness and competitiveness of measurement opportunities of different carriers themselves.

It should be understood that, in this embodiment of the present application, the first carrier may be an inter-frequency carrier or an intra-frequency carrier. The at least two carriers to which the second measurement configuration information is applied may be the same frequency carrier or the inter-frequency carrier, or may include the same-frequency carrier and the inter-frequency carrier, or may include other standard carriers. . The embodiments of the present application are not limited herein.

Optionally, as an embodiment, the first parameter is determined according to the first measurement configuration information of each carrier and the second measurement configuration information of the at least two carriers.

Specifically, the second measurement configuration information includes measurement configuration information applied to at least two carriers. Among the at least two carriers, the first carrier is included. And, each of the at least two carriers corresponds to one measurement configuration information. For example, the example shown in FIG. 4 will be described as an example. The second measurement configuration information includes measurement configuration information applied to carriers 1 to 5. The second measurement configuration information may be a measurement interval pattern. Each of the carriers 1 to 5 has a corresponding SMTC pattern. The five SMTC patterns can be understood as the first measurement configuration information corresponding to each carrier. That is, the first measurement configuration information corresponding to each carrier is different. It should be understood that the measurement configuration information corresponding to each of the carriers 1 to 5 is referred to as the first measurement configuration information, but the contents of the five first measurement configuration information, for example, the period and the like are different. Alternatively, the measurement configuration information corresponding to each carrier may be named as different measurement configuration information, and distinguished by name. For example, the measurement configuration information corresponding to carriers 1 to 5 may be respectively referred to as: carrier measurement configuration information No. 1, carrier measurement configuration information No. 2, carrier measurement configuration information No. 3, carrier measurement configuration information No. 4, carrier measurement configuration No. 5 information. The embodiments of the present application are not limited herein. The first parameter is determined according to the measurement configuration information corresponding to each carrier and the second measurement configuration information of the at least two carriers. For example, the example shown in FIG. 4 will be described as an example. The first parameter is determined according to the measurement interval pattern information and the SMTC pattern information corresponding to the five carriers respectively. In other words, the first parameter is determined according to measurement configuration information corresponding to each of the at least two carriers, second measurement configuration information applied to the multiple carriers, and first measurement configuration information on the first carrier. . In this embodiment, the first parameter is determined by using the measurement configuration information corresponding to each carrier and the second measurement configuration information, and various measurement configuration information related to the first carrier is fully considered . It is ensured that differentiating processing is performed for different carriers. The parameters corresponding to different carriers can be different. It improves the fairness and competitiveness of measurement opportunities of different carriers themselves.

It should be understood that the first parameter may also be determined based on other measurement configuration information associated with the first carrier. The embodiments of the present application are not limited herein.

Optionally, as an embodiment, the first parameter is determined according to a total number of carriers of the at least two carriers that collide with the first measurement configuration information of the first carrier.

Specifically, an example will be described as shown in FIG. 4 . The second measurement configuration information includes measurement configuration information applied to carriers 1 to 5. Assuming that the first carrier is carrier 1, the measurement configuration information of carrier 1 may be the SMTC pattern of carrier 1. It can be seen that since the terminal needs to perform measurement on carrier 1 according to the second measurement configuration information. However, the second measurement configuration information is simultaneously applied to carriers 2 to 5. Therefore, when measuring carrier 1, it is likely that there will be a conflict with the measurement of carriers 2 to 5 by the terminal device. For example, at the same time, the signal on the carrier 1 is measured according to the second measurement configuration information, and the signals on the

carriers

2 and 3 are also measured according to the second measurement configuration information. A measurement collision may occur with the first carrier at the same time. That is, at the same time, the terminal device measures other carriers in addition to the first carrier. A measurement conflict will occur. Therefore, the first parameter is determined according to a total number of carriers of the at least two carriers that collide with the first measurement configuration information of the first carrier. That is, at the same time, it is determined by the total number of carriers with measurement collisions including the first carrier. By determining the first parameter in this way, it can be more accurately and truly reflected that the first parameter corresponds to the first carrier. Improve the accuracy of the first parameter. The first parameter can more accurately reflect the fairness and competitiveness of measurement opportunities of different carriers themselves.

It should be understood that, in the application embodiment, the first parameter may also be determined according to the first measurement configuration information and the second measurement configuration information, or other configuration information related to the first carrier. The embodiments of the present application are not limited herein.

Optionally, when the first parameter is determined according to the number of valid detection carriers of the terminal device, for example, as shown in FIG. 4, if the terminal has the capability to perform SSB measurement on carriers 1 to 5 at the same time, for carrier 1 In this case, the first parameter may also be equal to the total number of carriers that have collision with carrier 1 minus 4, ie for carrier 1, the first parameter may be 1. Alternatively, for carrier 1, the first parameter may also be at least one of the same number of carriers minus the interval of the measurement window of carrier 1 minus 4. That is, the first parameter is 1. It should be understood that, when the first parameter is determined according to the number of valid detection carriers of the terminal device, the minimum value of the first parameter is 1. The network device can configure different measurement configuration information for different terminal devices according to the first parameter reported by the terminal device. Improve the measurement performance and user experience of the terminal device.

Optionally, as an embodiment. The first measurement configuration information includes a measurement window, and the second measurement information includes a measurement interval. The collision then includes: the measurement interval on the carrier included in the at least two carriers is at least one of the measurement interval in which the measurement window on the first carrier is located.

in particular. For each carrier, the first measurement configuration information may include a measurement window (receiving window) configured by the network device to notify the terminal device of the period or position when receiving or measuring the measurement window on the carrier. The second measurement configuration information includes a measurement interval. The second measurement configuration information is also configured by the network device, and is used to notify the terminal device of measurement information and the like when measuring multiple carriers. For example, the terminal device may perform cell identification or measurement operation or the like on the plurality of carriers within each measurement interval (Measurement Gap) notified by the second measurement configuration information. And the collision between the at least two carriers and the first measurement configuration information of the first carrier includes: a measurement interval where a measurement window on a carrier included in the at least two carriers is located, and a measurement window on the first carrier At least one measurement interval is the same. That is, the total number of carriers that need to be measured, including the first carrier itself, within the same measurement interval. Using the above method to determine whether a collision occurs, the result can be obtained accurately and quickly. Improve the efficiency of the terminal device to determine the first parameter.

For example, the example shown in FIG. 4 will be described as an example. The second measurement configuration information includes a measurement interval period of 40 ms, and for carriers 1 to 5, the SMTC periods are 20 ms, 40 ms, 80 ms, 160 ms, and 160 ms, respectively. It is assumed that the first carrier is carrier 1, and the at least two carriers are 5 carriers. The at least two carriers include carrier 1. For carrier 1 itself, the measurement interval of each SSB receiving window is the same as carrier 1 itself, and carrier 1 itself can be considered to collide with itself. The measurement interval at which the second SSB receive window on carrier 2 is located is within the same measurement interval as the third SSB receive window on carrier 1. Carrier 2 can also be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 3 is located is within the same measurement interval as the first SSB receive window on carrier 1. Carrier 3 can be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 4 is located is within the same measurement interval as the third SSB receive window on carrier 1. Carrier 4 can be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 5 is located is within the same measurement interval as the seventh SSB receive window on carrier 1. Carrier 5 can be considered to collide with carrier 1. Therefore, among the five carriers, the total number of carriers that collide with carrier 1 is five. That is, for carrier 1, the value of the first parameter is 5.

Similarly, for carrier 2, the measurement interval of the SSB window on carrier 2 is {0, 1, 2, 3, 4, ...}. The measurement interval of the SSB window on carrier 3 is {0, 2, 4, 8, 10, ...}. The measurement interval of the SSB window on carrier 4 is {1, 5, 9, 13, 17, ...}. The measurement interval of the SSB window on carrier 5 is {3, 7, 11, 15, 19, ...}. Correspondingly, the other carriers having the "SSB measurement interval collision" with the carrier 2 are

carriers

1, 3, 4, and 5, and the first parameter corresponding to the carrier 2 has a value of 5. The other carriers having the "SSB measurement interval collision" with the carrier 3 are

carriers

1, 2, and the first parameter corresponding to the carrier 3 has a value of 3. The other carriers having the "SSB measurement interval collision" with the carrier 4 are

carriers

1, 2, and the first parameter corresponding to the carrier 4 has a value of 3. The other carriers having the "SSB measurement interval collision" with the carrier 5 are 1, 2, and the first parameter corresponding to the carrier 5 has a value of 3.

Optionally, as an embodiment. The first measurement configuration information includes a measurement window, the second measurement information includes a measurement interval, and the collision includes at least one measurement window on the carrier included in the at least two carriers, and at least one measurement on the first carrier Window, within the same measurement interval.

in particular. For each of the multiple carriers, the first measurement configuration information may include measurement window (receiving window) information, and the measurement window is configured by the network device to notify the terminal device to receive or measure the period or position of the measurement window. . The second measurement information includes a measurement interval and the like. The second measurement configuration information is also configured by the network device, and is used to notify the terminal device of measurement information and the like when measuring multiple carriers. The terminal device may perform cell identification or measurement operation, etc. on the plurality of carriers within each measurement interval (Measurement Gap). And the collision of the first measurement configuration information of the first carrier, the at least one measurement window included in the carrier of the at least two carriers, and the at least one measurement window on the first carrier are Within the same measurement interval. That is, within the same measurement interval, in addition to the first carrier, there are measurement windows of other carriers within the measurement interval.

For example, as shown in FIG. 4, an example will be described. The measurement interval period is 40 ms. For carriers 1 to 5, the SMTC periods are 20 ms, 40 ms, 80 ms, 160 ms, and 160 ms, respectively. It is assumed that the first carrier is carrier 1, and the at least two carriers include 5 carriers. The at least two carriers include carrier 1. For carrier 1, the measurement interval in which the first SSB measurement window and the second SSB reception window on carrier 2 are located is within the same measurement interval. Carrier 2 can also be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 3 is located is within the same measurement interval as the first SSB receive window on carrier 1. Carrier 3 can be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 4 is located is within the same measurement interval as the third SSB receive window on carrier 1. Carrier 4 can be considered to collide with carrier 1. The measurement interval at which the first SSB receive window on carrier 5 is located is within the same measurement interval as the seventh SSB receive window on carrier 1. Carrier 5 can be considered to collide with carrier 1. Therefore, among the five carriers, the total number of carriers that collide with carrier 1 is five. That is, except for the carrier 1, the number of carriers (four) that collide with the carrier 1 is increased by one to obtain the total number of carriers that collide with the carrier 1, and for the carrier 1, the value of the first parameter is five.

Optionally, as an embodiment. The first measurement configuration information includes a measurement window, the second measurement information includes a measurement interval, and the collision includes a measurement interval in which a measurement window on the carrier included in the at least two carriers is located, and a measurement on the first carrier The measurement intervals at which the windows are located are all the same or all overlap.

Specifically, for example, as shown in FIG. 4, the measurement interval period is 40 ms, and for carriers 1 to 5, the SMTC periods are 20 ms, 40 ms, 80 ms, 160 ms, and 160 ms, respectively. It is assumed that the first carrier is carrier 1, and the at least two carriers include 5 carriers. The at least two carriers include carrier 1, and each SSB receiving window on carrier 2 is all the same or all overlaps with the time interval of the receiving window of the SSB on carrier 1. That is, carrier 2 needs to be measured when measuring carrier 1 in any one measurement interval. Therefore, carrier 2 and carrier 1 collide.

Optionally, as an embodiment. The first measurement configuration information includes a measurement window, the second measurement information includes a measurement interval, and the collision includes a measurement interval in which a measurement window on the carrier included in the at least two carriers is located, and a measurement on the first carrier The measurement interval at which the window is located is partially the same or partially overlapped.

Specifically, for example, as shown in FIG. 4, the measurement interval period is 40 ms, and for carriers 1 to 5, the SMTC periods are 20 ms, 40 ms, 80 ms, 160 ms, and 160 ms, respectively. It is assumed that the first carrier is carrier 1, and the at least two carriers include 5 carriers. The measurement interval at which each SSB window on carrier 3 is located is only partially measured or overlapped with the measurement interval at which the reception window of the SSB on wave 1 is located. For example, within the measurement interval in which the second SSB receive window on carrier 1 is located, there is no need to perform SSB receive window measurements on carrier 3. That is, only on a part of the measurement interval in the measurement interval in which all the SSB reception windows of the carrier 1 are located, when the carrier 1 is measured, the carrier 3 is also required to be measured. Therefore, carrier 3 and carrier 1 collide. Similarly, for carriers 4 and 5, it is also collision with carrier 1.

It should be understood that if the terminal is configured with a measurement interval that is used for both NR carrier measurement and heterogeneous carrier measurement, then these heterogeneous carriers are considered to have "measurement interval collision" with other NR carriers. The heterogeneous carrier includes, but is not limited to, LTE, Evolved Universal Terrestrial Radio Access Network (UTRAN), GSM, High Rate Packet Data (HRPD), and the like. The embodiments of the present application are not limited herein.

It should also be understood that the explanation or description of the collision may also be other related descriptions, but the nature of the collision is within the same measurement interval, in addition to the first carrier, there are measurement windows of other carriers in the measurement. Measurements are required during the interval. Therefore, there may be other similar descriptions for the collision. All should be covered within the scope of this application. The embodiments of the present application are not limited herein.

Optionally, as an embodiment, the measurement window included in the first measurement configuration information includes at least one of a measurement window start position, a measurement window duration, and a measurement window period. The measurement interval included in the second measurement information includes at least one of a measurement interval start position, a measurement interval duration, and a measurement interval period.

Specifically, for each carrier, the network device configures corresponding measurement configuration information for notifying the terminal device of the period of measuring or receiving the signal on the carrier. Accordingly, the measurement window further includes at least one of a measurement window start position, a measurement window duration, and a measurement window period. According to the measurement window start position on each carrier, the measurement window duration and other information, the terminal device can actually determine when the measurement is needed, the length of the measurement time, and the like. Taking the example shown in FIG. 3 as an example, the starting position of the measuring window is equivalent to the starting position of the SSB receiving window, the measuring window duration is equivalent to the length of the SSB receiving window, and the measuring window period is equivalent to the SMTC period. The measurement interval included in the second measurement information includes at least one of a measurement interval start position, a measurement interval duration, and a measurement interval period. It is used to notify the terminal device that the measurement of the signal to the plurality of carriers, and the like can be performed within the measurement intervals. The measurement interval start position is used by the terminal device to determine the location of the measurement interval. The measurement interval duration is equivalent to the length of time of the measurement interval. The measurement interval period is equivalent to the length of time between every two measurement intervals. For example, as shown in FIG. The measurement interval period (measurement interval repetition period) is 40 ms. When the first measurement configuration information and the second measurement configuration information include the foregoing content, the first measurement requirement determined by the terminal device may be more accurately and truly reflected on the characteristics of the first carrier. Improve the accuracy of the first parameter and the first measurement requirement. The first measurement requirement can more realistically reflect the fairness and competitiveness of the measurement opportunities of different carriers themselves.

It should be understood that the measurement window included in the first measurement configuration information may further include other information related to the measurement window. The measurement interval included in the second measurement information is also included in the information related to the measurement interval. The embodiment of the present application is not limited herein.

Optionally, as an embodiment, in S210, the terminal device determines, according to the first measurement configuration information, the second measurement configuration information, and the first parameter of the first carrier, the first measurement requirement on the first carrier, including The terminal device determines the first measurement requirement according to the measurement window period on the first carrier, the measurement interval period, and the first parameter.

Specifically, since the first measurement information includes the measurement window period, the second measurement information includes the measurement interval period. Therefore, the terminal device may determine the first measurement requirement according to the measurement window period on the first carrier, the measurement interval period, and the first parameter. In this way, the determined first measurement requirement can reflect the characteristics of the first carrier more accurately and truly. Improve the accuracy of the first measurement requirement. This makes the first measurement requirement more realistically reflect the fairness and competitiveness of measurement opportunities of different carriers themselves. On the basis of fully considering the measurement opportunities of each carrier, the measurement delay of the terminal device can also be reduced. At the same time, excessive requirements on the measurement capability of the terminal device are avoided, and the cost of the terminal device is reduced. Improve the user experience.

Optionally, as an embodiment, the terminal device determines the first measurement requirement according to the measurement window period, the measurement interval period, and the first parameter on the first carrier, including:

Determining the first measurement requirement according to the following formula (1),

S=R×Max(T1,T2)×A (1)

Where S is the value of the measurement index of the first measurement requirement, R is a constant, T1 is the measurement window period, T2 is the measurement interval period, and Max (T1, T2) is the larger value of T1 and T2. , A is the first parameter.

Specifically, the terminal device can calculate the value of the measurement index corresponding to the first measurement requirement according to the above formula (1). R is a constant (corresponding to a coefficient), and the value of R is a positive number. T1 is a measurement window period corresponding to the first carrier included in the first measurement configuration information, and measurement window periods corresponding to different carriers may be different. T2 is a measurement interval period for the plurality of carriers included in the second measurement configuration information. The value of Max(T1, T2) is the larger of T1 and T2, and A is the first parameter corresponding to the first carrier.

The example shown in FIG. 4 will be described as an example. Assuming that the first carrier is carrier 1, the measurement window period of the first carrier is 20 ms, that is, the value of T1 is 20 ms. T2 is a measurement interval period for the 5 carrier included in the second measurement configuration information, that is, for carriers 1 to 5, the value of T2 is 40 ms. Then the value of Max(T1, T2) is 40ms. According to the related explanation of the first parameter, it can be concluded that the first parameter corresponding to the carrier is 5. R is a predefined constant. Therefore, based on the values of the above parameters, the value of the measurement index of the first measurement demand on the first carrier can be calculated. Similarly, for carriers 2 to 5, the values of the measurement indicators of the measurement requirements corresponding to each carrier can be separately calculated by the above method.

Alternatively, in equation (1), R may represent the number of measurement opportunities required. For example, if the first measurement requirement (measurement indicator) is the cell identification time/delay, then R represents the number of measurement opportunities required during the time identified by the cell. If the first measurement requires the detection time of the Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS), then R indicates the number of measurement opportunities required during the PSS/SSS detection time. If the measurement index is the SSB index detection time, it indicates the number of measurement opportunities required for the SSB index detection time. If the first measurement requirement is the SSB measurement period, then R represents the number of measurement opportunities required to obtain an SSB measurement within the time. It should be understood that for different carriers, the R values may be the same or different. For different measurement indicators, the R values may be the same or different.

Determining the first measurement requirement according to the following formula (2),

S=Max(T1,T2)×A (2)

Where S is the value of the measurement index of the first measurement requirement, T1 is the measurement window period, T2 is the measurement interval period, and Max (T1, T2) is the larger value of T1 and T2, and A is the value The first parameter.

Specifically, in addition to calculating the value of the measurement index corresponding to the first measurement demand by using the above formula (1), the value of the measurement index corresponding to the first measurement demand may be calculated using the formula (2). A constant coefficient is not required to correct the calculation. T1 is a measurement window period corresponding to the first carrier included in the first measurement configuration information, and measurement window periods corresponding to different carriers may be different. T2 is a measurement interval period for the plurality of carriers included in the second measurement configuration information. The value of Max(T1, T2) is the larger of T1 and T2, and A is the first parameter corresponding to the first carrier. The calculation method is similar to the above. For the sake of brevity, we will not go into details here.

By using the above formulas (1) and (2) to calculate the value of the measurement index of the first measurement requirement, the first measurement requirement can be quickly and accurately obtained, and the efficiency of the carrier detection by the terminal device is improved. Improve the user experience.

It should be understood that in addition to using the above formulas (1) and (2) to calculate the value of the measurement index of the first measurement demand, other formulas may be utilized, for example, between S and Max (T1, T2), A, and R. The relationship can also satisfy any possible form of quadratic functions, exponential functions, and the like. The embodiments of the present application are not limited herein.

Optionally, as an embodiment, the first measurement configuration information of the first carrier is first measurement configuration information of the synchronization signal block SSB on the first carrier.

Specifically, if the first measurement configuration information of the first carrier is the first measurement configuration information of the SSB on the first carrier, as shown in FIG. 3 or FIG. 4 .
