DETAILED DESCRIPTION OF EMBODIMENTS

The subject matter described herein will now be discussed with reference to several example embodiments. It should be understood these embodiments are discussed only for the purpose of enabling those skilled persons in the art to better understand and thus implement the subject matter described herein, rather than suggesting any limitations on the scope of the subject matter.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a, ” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises, ” “comprising, ” “includes” and/or “including, ” when used herein, specify the presence of stated features, integers, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.

It should also be noted that in some alternative implementations, the functions/acts noted may occur out of the order noted in the figures. For example, two functions or acts shown in succession may in fact be executed concurrently or may sometimes be executed in the reverse order, depending upon the functionality/acts involved.

As used herein, the term “communication network” refers to a network following any suitable communication standards, such as Long Term Evolution (LTE) , LTE-Advanced (LTE-A) , Wideband Code Division Multiple Access (WCDMA) , High-Speed Packet Access (HSPA) , and so on. Furthermore, the communications between a terminal device and a network device in the communication network may be performed according to any suitable generation communication protocols, including, but not limited to, the first generation (1G) , the second generation (2G) , 2.5G, 2.75G, the third generation (3G) , the fourth generation (4G) , 4.5G, the future fifth generation (5G) communication protocols, and/or any other protocols either currently known or to be developed in the future.

Embodiments of the present disclosure may be applied in various communication systems. Given the rapid development in communications, there will of course also be future type communication technologies and systems with which the present disclosure may be embodied. It should not be seen as limiting the scope of the present disclosure to only the aforementioned system. For the purpose of illustrations, embodiments of the present disclosure will be described with reference to EN-DC network in 5G communication system.

The term “communication device” may refer to a network device and/or a terminal device. The term “network device” includes, but not limited to, a base station (BS) , a gateway, a management entity, and other suitable device in a communication system. The term “base station” or “BS” represents a node B (NodeB or NB) , an evolved NodeB (eNodeB or eNB) , a Remote Radio Unit (RRU) , a radio header (RH) , a remote radio head (RRH) , a relay, a low power node such as a femto, a pico, and so forth.

The term “terminal device” includes, but not limited to, “user equipment (UE) ” and other suitable end device capable of communicating with the network device. By way of example, the “terminal device” may refer to a terminal, a Mobile Terminal (MT) , a Subscriber Station (SS) , a Portable Subscriber Station, a Mobile Station (MS) , or an Access Terminal (AT) .

The term “measurement gap” used herein refers to a gap during which no transmission and reception happens. Since there is no signal transmission and reception during the gap, the terminal device can switch to the target cell and perform the signal quality measurement and come back to the current cell.

The term “circuitry” used herein may refer to one or more or all of the following:

(a) hardware-only circuit implementations (such as implementations in only analog and/or digital circuitry) and

(b) combinations of hardware circuits and software, such as (as applicable) :

(i) a combination of analog and/or digital hardware circuit (s) with

software/firmware and

(ii) any portions of hardware processor (s) with software (including digital signal processor (s) ) , software, and memory (ies) that work together to cause an apparatus, such as a mobile phone or server, to perform various functions) and

(c) hardware circuit (s) and or processor (s) , such as a microprocessor (s) or a portion of a microprocessor (s) , that requires software (e.g., firmware) for operation, but the software may not be present when it is not needed for operation. ”

This definition of circuitry applies to all uses of this term in this application, including in any claims. As a further example, as used in this application, the term circuitry also covers an implementation of merely a hardware circuit or processor (or multiple processors) or portion of a hardware circuit or processor and its (or their) accompanying software and/or firmware. The term circuitry also covers, for example and if applicable to the particular claim element, a baseband integrated circuit or processor integrated circuit for a mobile device or a similar integrated circuit in server, a cellular network device, or other computing or network device.

As described above, embodiments of the present disclosure is described with reference to the EN-DC network in 5G communication system. Due to the higher frequencies bands used and other reasons, it is deemed better to enable terminal devices to connect to LTE and 5G New Radio (NR) simultaneously. This is referred to as Dual Connectivity EN-DC. In some embodiments, the LTE eNB is referred to as the MNB to indicate that it is the ‘Master’ base station (i.e., Master Node, MN) controlling the ‘Secondary’ 5G NR base station (i.e., Secondary Node, SN) . In the scenario of EN-DC, if the terminal device needs to measure the signal quality of the target cell, which node to decide the type of measurement still needs to be discussed.

If the MN decides the type of measurement, the MN informs the SN and the terminal device. However, if the SN is the first node that tends to configure the type of measurement and the SN does not receive any information regarding the measurement, the behaviors of the SN have not decided yet. There are two options regarding the behaviors of the SN.

Option 1. If the SN first configures the measurement, the SN transmits all measured frequencies to the MN via CG-Config signaling. After the MN decides the type of measurement, the MN informs the SN the decided type via CG-ConfigInfo signaling. Option 2. If the SN first configures the measurement, the SN decides the type of measurement and informs the decided type to the MN via CG-Config signaling.

Compared with Option 1, Option 2 can reduce the network implementation. However, for Option 2, the SN needs an extra explicit indication in CG-Config to inform the MN the decided type. In particular, if the SN can change the type dynamically, the signaling procedure between the MN and the SN will become much more complex. Further, if the MN and the SN decide different types of measurement, the behaviors of the SN and the terminal device are not discussed yet.

In order to at least in part solve above and other potential problems, embodiments of the present disclosure provide solutions for signal quality measurements between cells. According to embodiments of the present disclosure, the priorities of types of measurement gap are defined and the terminal device and/or the network device are able to determine the type of measurement gap based on the defined priorities. Thus, embodiments of the present disclosure can achieve the determination of measurement gap without introducing other signaling.

Now some example embodiments of the present disclosure are described below with reference to the figures. However, those skilled in the art would readily appreciate that the detailed description given herein with respect to these figures is for explanatory purpose as the present disclosure extends beyond theses limited embodiments.

Fig. 1 illustrates a schematic diagram of a communication system in which embodiments of the present disclosure can be implemented. The communication system 100, which is a part of a communication network, includes

network devices

120 and 130, and terminal devices 110-1, 110-2, ..., 110-2, where N is an integer number. It is to be understood that the communication system 100 may include any suitable number of terminal devices. It should be noted that the communication system 100 may also include other elements which are omitted for the purpose of clarity. The

network devices

120 and 130 may communicate with the terminal devices 110. The network device 120 and the network device 130 may communicate with each other. It is to be understood that the number of network devices and terminal devices shown in Fig. 1 is given for the purpose of illustration without suggesting any limitations. The communication system 100 may include any suitable number of network devices and terminal devices. Only for the purpose of illustrations, the network device 120 is referred to as an MN hereinafter and the network device 130 is referred to as an SN hereinafter.

Communications in the communication system 100 may be implemented according to any proper communication protocol (s) , including, but not limited to, cellular communication protocols of the first generation (1G) , the second generation (2G) , the third generation (3G) , the fourth generation (4G) and the fifth generation (5G) and on the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and/or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any proper wireless communication technology, including but not limited to: Code Divided Multiple Address (CDMA) , Frequency Divided Multiple Address (FDMA) , Time Divided Multiple Address (TDMA) , Frequency Divided Duplexer (FDD) , Time Divided Duplexer (TDD) , Multiple-Input Multiple-Output (MIMO) , Orthogonal Frequency Divided Multiple Access (OFDMA) and/or any other technologies currently known or to be developed in the future.

Fig. 2 illustrates an interaction operation 200 among the terminal device 110, the network device 120 and the network device 130. Only for the purpose of illustrations, Fig. 2 is described with reference to the scenario of EN-DC network. It should be noted that the interaction operation may be implemented in any suitable communication network.

The network device 130 configures 2010 a type of measurement gap to the terminal device 110. For example, if the network device 130 is an SN which needs an FR2 gap pattern for measurement, it configures the FR2 measurement gap to the terminal device 110 directly without informing the network device 120 (i.e., the MN) . It should be noted that the FR2 gap measurement gap is only an example of a per frequency range (FR) measurement gap. The per frequency range measurement gap may also include an FR1 gap pattern. FR1 used herein refers to the frequency range which is below 6GHz and FR2 used herein refers to the frequency range which is above 24GHz. It should be noted that the network device 130 may configure any suitable types of measurement gap. The per UE measurement gap, the per frequency range measurement gap and the per CC measurement gap are only examples and embodiments of the present disclosure are not limited in this aspect.

In some embodiments, if the network device 120 needs the same gap pattern as the network device 130, it may transmit 2020 a request to the network device 130. The terminal device 110 may perform 2030 the measurement using the FR gap pattern.

The network device 120 transmits 2040 information indicating a further type of measurement gap to the network device 120 and also transmits 2050 the information to the terminal device 110. It should be noted that the network device 120 may transmit the information to the network device 130 and the terminal device 120 simultaneously or in any suitable order. In some embodiments, the further type of measurement gap may be a per user equipment (UE) measurement gap. The further type of measurement gap may also be a per component carrier (CC) measurement gap. Alternatively or in addition, the further type of measurement gap may be a FR2 measurement gap.

The terminal device 110 compares 2070 the priorities of the type of measurement gap and the further type of measurement gap. The network device 130 compares 2060 the priorities of the type of measurement gap and the further type of measurement gap. It should be noted that the comparisons 2060 and 2070 may be performed in any suitable manner.

The terminal device 110 and the network device 130 may perform the comparisons based on predetermined priorities. In some embodiments, the predetermined priorities may be preconfigured to the terminal device 110 and the network device 130. In some embodiments, the priorities may be defined by the operator of the communication system 100. For example, in some embodiments, the per UE measurement gap may have a greater priority than the per FR measurement gap and the per FR measurement gap may have a greater priority than per CC measurement gap. In this way, the terminal device 120 may achieve the determination of measurement gap without introducing other signaling. The predetermined priorities may be stored locally in the terminal device 110 and/or the

network devices

120 and 130. In other embodiments, the predetermined priorities may be stored in remote storage which can be accessed by the terminal device 110 and/or the

network devices

120 and 130.

The terminal device 110 performs 2090 the measurement based on the comparison. For example, the terminal device 110 may perform the measurement using the type of measurement gap with a greater priority. By way of example, if the further type is the per UE measurement gap which has a greater priority than the FR1 type, the terminal device 110 may perform the measurement using the per UE measurement gap. If the further type is the per CC measurement gap which has a lower priority than the FR1 type, the terminal device 110 may perform the measurement using the FR1 type.

In some embodiments, if the type of measurement gap is FR1 and the further type of measurement gap is FR2, the terminal device 110 may perform the measurement using FR1 for FR1 measured objects and perform the measurement using FR2 for FR2 measured objects.

In an example embodiment, the network device 130 override 2080 the type of measurement based on the comparison. For example, the network device 130 may override the type of measurement with a greater priority. By way of example, if the further type is the per UE measurement gap which has a greater priority than the FR1 type, the network device 130 may override the FR1 type with the per UE measurement gap.

In some embodiments, the network device 120 may also transmit information indicating that the further type of measurement gap is to be used. For example, if the network device 120 may transmit the information that the FR1 type is to be used and the terminal device 130 perform the measurement using the per UE measurement gap, the terminal device 130 may remove the per UE measurement gap firstly and then perform the measurement using the FR1 type.

In a further embodiment, the network device 120 may transmit 2110, to the network device 130, further information for de-configuring the further type and may also transmit 2120 the further information to the terminal device 110. The network device 130 may resume 2130 the type of measurement gap and the terminal device 2140 may also resume 2140 the type of measurement gap.

Fig. 3 illustrates a flow chart of method 300 in accordance with embodiments of the present disclosure. The method 300 may be implemented at the terminal device 110. The method 300 may also be implemented at the network device 130. For the purpose of illustrations, the method 300 is described with the reference to the terminal device 110.

At block 310, the terminal device 110 receives information indicating a type (referred to as the first type) of measurement gap for measurement of signal quality. The first type may be a per UE measurement gap. The first type may also be a per CC measurement gap. Alternatively or in addition, the first type may be a per FR measurement gap. In some embodiments, the first type of measurement gap is received from the network device 120. In other embodiments, the first type of measurement gap is received from the network device 130.

Another type (referred to as the second type) of measurement gap for measurement of signal quality may be configured previously. For example, the network device 130 may previously configure the second type of measurement gap to the terminal device 110. In other embodiment, the network device 120 may previously configure the second type of measurement gap to the terminal device 110. The first type of measurement gap and the second type of measurement gap may be configured by the same network device. Alternatively or in addition, the first type of measurement gap and the second type of measurement gap may be configured by different network devices.

The terminal device 110 determines that the second type of measurement gap has been configured. At block 320, the terminal device 110 may compare the priority (referred to as the first priority) of the first type and the priority (referred to as the second priority) of the second type. For example, the terminal device 120 may compare the first and second priorities based on predefined priorities. In some embodiments, the priorities may be defined by the operator.

At block 330, the terminal device 110 performs the measurement of signal quality based on the comparing results. For example, if the first type has a greater priority than the second type, the terminal device 110 may perform the measurement using the first type. If the second type has a greater priority than the first type, the terminal device 110 may perform the measurement using the second type. In some embodiments, the terminal device 110 may ignore the first type of measurement and transmit indication for invalidity of configuring the first type of measurement gap to the network device 120. For example, the indication may indicate a failure of configuring the first type of measurement gap and/or a rejection to configuring the first type of measurement gap.

In an example embodiment, the terminal device 110 may receive information indicating that the first type is to be used. In this embodiment, if the second type has a greater priority than the first type, the terminal device 110 may remove the second type and perform the measurement using the first type. In some embodiments, the terminal device 110 may transmit indication for removing the second type of measurement gap to the network device which configures the second type of measurement gap.

In other embodiments, the first type of measurement gap and the second type of measurement gap may be used for different sets of frequencies. In this embodiment, the first type of measurement gap and the second type of measurement gap may be kept and the terminal device 110 may use the proper type of measurement gap the based on the frequencies or the serving cells. That is to say, the terminal device 110 may use different types of measurement gaps to measure signal quality with data connection on different sets of frequencies and the different types of measurement gaps may coexist at the terminal device 110 regardless of their priorities.

In some embodiments, an apparatus for performing the method 300 (for example, the terminal device 110 and the network device 130) may comprise respective means for performing the corresponding steps in the method 300. These means may be implemented in any suitable manners. For example, it can be implemented by circuitry or software modules.

In some embodiments, the apparatus comprises: means for receiving information indicating a first type of measurement gap for measurement of signal quality means for in response to a determination that a second type of measurement gap for the measurement of signal has been configured, comparing a first priority of the first type and a second priority of the second type; and means for performing the measurement of signal quality at least in part based on the comparison.

In some embodiments, the means for performing the measurement of signal quality comprises: means for in response to the first priority being greater than the second priority, overriding the second type of measurement gap; means for performing the measurement of signal quality using the first type of measurement gap; and means for in response to the second priority being greater than the first priority, performing the measurement of signal quality using the second type of measurement gap.

In some embodiments, the means for performing the measurement of signal quality comprises: means for in response to the information indicating that the first type of measurement gap is to be used, removing the second type of measurement gap if the second priority is greater than the first priority; and means for performing the measurement of signal quality using the first type.

In some embodiments, the first type of measurement gap may comprise at least one of the followings: a per user equipment measurement gap, a per frequency range measurement gap, and a per component carrier measurement gap.
