[0019] The subject matter described herein will now be discussed with reference to several example embodiments. It should be understood that these embodiments are discussed only for the purpose of enabling those skilled in the art to better understand and thereby implement the subject matter described herein, and do not imply any limitation on the scope of the subject matter.

[0020] The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments. As used herein, the singular forms of "a", "an", and "the" are also intended to include plural forms unless the context clearly indicates otherwise. It should be further understood that when used herein, the terms "include", "comprise", "include", "include" and / or "include" specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or increase of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.

For example, depending on the functions / actions involved, two functions or actions shown in succession may actually be performed simultaneously, or may sometimes be performed in the reverse order.

[0022] As used herein, the term "communication network" refers to a network that complies with any suitable communication standard, such as Long Term Evolution (LTE), Advanced LTE (LTE-A), Wideband Code Division Multiple Access (WCDMA), High Speed ​​Packet Access (HSPA), etc. In addition, the communication between the terminal device and the network equipment in the communication network can be performed according to any suitable generation of communication protocols, including but not limited to first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, future fifth generation (5G) communication protocols and / or any other protocols currently known or to be developed in the future.

[0023] Embodiments of the present disclosure may be applied to various communication systems. Considering the rapid development of communications, of course, there will be future types of communication technologies and systems that may embody the present disclosure. The scope of the present disclosure should not be limited to only the above-mentioned systems.

[0024] The term "network device" includes, but is not limited to, a base station (BS), a gateway, a management entity, and other suitable equipment in a communication system. The term "base station" or "BS" means a Node B (NodeB or NB), an evolved NodeB (eNodeB or eNB), a remote radio unit (RRU), a radio head (RH), a remote radio head (RRH), a relay, a low power node (e.g., a femto, a pico, etc.).

[0025] The term "terminal device" includes, but is not limited to, "user equipment (UE)" and other suitable terminal devices capable of communicating with network devices. For example, "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).

[0026] The term "intra-frequency measurement" used in this article refers to measuring the signal quality of the serving cell and / or the target cell if the target cell is in the same frequency band as the current serving cell of the terminal device. The term "inter-band measurement" used in this article refers to measuring the signal quality of the target cell if the target cell is in a different frequency band than the current serving cell of the terminal device.

[0027] The term "component carrier" as used herein refers to each carrier in a carrier aggregation. The term "primary component carrier" as used herein refers to the primary carrier in any group.

[0028] As mentioned above, the terminal device needs to perform communication measurements on the carrier component. Some agreement has been reached on the following measurement requirements. The term "FR1" used in this article refers to the frequency range below 6 GHz, and the term "FR2" used in this article refers to the frequency range above 24 GHz. Requirements for FR1

[0029] For each frequency inner layer, the terminal device shall be able to monitor at least 8 cells. For each frequency inner layer, during each layer 1 measurement period, the terminal device shall be able to monitor at least 14 SSBs (synchronization blocks) with different SSB indices and / or PCIs on the frequency inner layer, where the number of SBBs in the serving cell (except the secondary cell SCell) is not less than the number of configured radio link monitoring reference signal (RLM-RS) SSB resources.

[0030] FR2 requirements

[0031] For each frequency inner layer, the terminal device shall be able to monitor at least 6 cells on a single serving carrier among all serving carriers configured in the same frequency band.

[0032] For each intra-frequency layer, during each Layer 1 measurement period, the terminal device shall be able to monitor at least 24 SSBs with different SSB indices and / or PCIs on a single serving carrier among all serving carriers configured in the same frequency band (e.g., PCC or PSCC or 1 SCC if the PCC / PSCC is in a different frequency band than the SCC). The terminal device shall be able to monitor 1-4 SSBs on the serving cell for each other serving carrier in the same frequency band. The terminal device shall be able to perform Reference Signal Received Power (RSRP) and / or Reference Signal Received Quality (RSRQ) on all the above SSBs.

[0033] It can be seen from the protocol that, in addition to one primary component carrier, the terminal device may not perform cell detection on the in-band secondary component carriers. In addition, there is no consensus on whether the terminal device can measure 1, 2, 3 or 4 SSB-based beams for each in-band secondary component carrier.

[0034] Furthermore, the communication measurements may place a burden on the terminal device. In particular, considering FR2, the measurement bandwidth of 240kHz SSB results in high sampling rate and storage requirements on the terminal device side. In addition, it has been decided that the initial phase of the new radio will include intra-band carrier aggregation of up to 8 component carriers, covering bandwidths of up to 800MHz. Therefore, there is a need to investigate how to limit the measurement requirements of the terminal device to reduce the overall terminal device complexity and power consumption.

[0035] In conventional technology, since the initial stage of new radio covers intra-band carrier aggregation (CA) of up to 8 component carriers, the terminal device can only measure 1 component carrier per frequency band and other component carriers (intra-frequency CC) in the same frequency band do not need to be measured. However, in the above solution, there is a question as to how the network will be able to receive load information from other component carriers unless measured.

[0036] The number of SSB-based beams that the terminal device needs to monitor has not yet been determined. In conventional techniques, if the terminal device measures one in-band component carrier, the measurement result of the one component carrier can represent any measurement of all other component carriers in the same band as the measured component carrier. That is, the terminal device will need to perform measurements on one in-band component carrier and will not need to measure any other in-band component carrier other than the primary component carrier. However, the above solution depends on the network deployment and cannot be used as a general assumption for formulating general terminal device measurement requirements.

[0037] In addition, in conventional technology, if all in-band component carriers are collocated, have the same directional orientation (or direction) and have the same or similar coverage (e.g., the same transmit power and the same beam coverage), the measurement workload and burden of the terminal device can be reduced. However, the above solution may be too restrictive for further deployment of the network.

[0038] Furthermore, it is not clear what is required on the network side in terms of the measurement capabilities of the terminal equipment and the information used to measure the auxiliary information.

[0039] In conventional technology, in LTE carrier aggregation, a terminal device can measure any configured component carrier according to the communication measurement requirements, where the measurement period for deactivated SCells is different from the measurement period for activated SCells. These requirements can be assumed as a benchmark for new radios. However, in current protocols, these requirements may not be suitable.

[0040] In order to at least partially solve the above and other potential problems, embodiments of the present disclosure provide solutions for new radio management measurements. Now, some example embodiments of the present disclosure are described below with reference to the accompanying drawings. However, those skilled in the art will readily appreciate that since the present disclosure goes beyond these limited embodiments, the detailed description given herein with respect to these drawings is for illustrative purposes.

[0041] Figure 1 1 is a schematic diagram of a communication system in which embodiments of the present disclosure may be implemented. The communication system 100, as part of a communication network, includes a network device 120 and one or more terminal devices 110-1 and 110-2. It should 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 that are omitted for clarity. The network device 120 may communicate with the terminal device 110. It should be understood that Figure 1 The number of network devices and terminal devices shown is given for illustrative purposes and does not imply any limitation. Communication system 100 may include any suitable number of network devices and terminal devices.

[0042] The communication in the communication system 100 can be implemented according to any appropriate communication protocol, including but not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G) and fifth generation (5G), wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol currently known or developed in the future. Moreover, the communication can utilize any appropriate wireless communication technology, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDMA), and / or any other technology currently known or developed in the future.

[0043] According to an embodiment of the present disclosure, the network device 120 may send the colocation information of the component carrier to the terminal device 110. For example, the network device 120 will indicate to the terminal device 110 whether the terminal device 110 can assume the same channel conditions for the component carrier (CC) (e.g., in-band CC) and therefore the terminal device 110 is allowed to relax the measurement requirements for certain CCs compared to the main CC. The terminal device 110 may perform measurements based on the colocation information. In this way, the measurement workload and burden of the terminal device 110 may be reduced while maintaining the flexibility of network deployment.

[0044] It should be noted that, for the purpose of illustration only and not limitation, the embodiments of the present disclosure are described using in-band measurements. Those skilled in the art will appreciate that the embodiments of the present disclosure may be implemented using any suitable communication measurements. For example, the measurements may include at least one of in-band measurements, inter-band measurements, and radio resource management (RRM) measurements. The present disclosure is not limited in this regard.

[0045] Figure 2 A flow chart of a method 200 according to an embodiment of the present disclosure is shown. The method 200 may be implemented at the network device 120.

[0046] At block 210, network device 120 determines a first direction of a beam associated with one or more component carriers. In some embodiments, network device 120 may determine the first direction based on a direction of a transmit antenna.

[0047] At block 220, the network device 120 determines collocation information of one or more component carriers. The collocation information indicates whether one or more component carriers are collocated with another component carrier, and beam direction information associated with at least one component carrier. If two component carriers are collocated with each other, it means that they have the same channel conditions. The network device 120 may determine whether the component carriers are collocated with each other based on their configuration. The collocation information may also include quasi collocation (QCL) information.

[0048] In an example embodiment, network device 120 may compare a first direction of one or more component carriers to a second direction of a beam associated with a primary component carrier.

[0049] If the similarity value between the first direction and the second direction exceeds a threshold similarity, the network device 120 may determine that the one or more component carriers are collocated with the primary component carrier and have the same beam direction. If the similarity value between the first direction and the second direction does not exceed the threshold similarity, the network device 120 may determine that the one or more component carriers are not collocated with the primary component carrier, or are collocated but do not have the same beam direction.

[0050] In other embodiments, the network device 120 may compare the first direction with a third direction of a beam associated with a group of component carriers. If the similarity value between the first direction and the third direction exceeds a threshold, the network device 120 may determine that the one or more component carriers and the group of component carriers may be grouped into a collocated group having the same beam direction or beam angle. In other embodiments, the one or more component carriers and the group of component carriers may be grouped into a collocated group not having the same beam direction or beam angle.

[0051] At block 230, the network device 120 sends at least one of the collocation information and the information of the first direction of the beam associated with at least one of the one or more component carriers to the terminal device 110. In some embodiments, the network device 120 determines the primary component carrier from the collocated component carrier group. The terminal device 120 may send the information of the determined primary component carrier as shown in Table 1 below.

[0054]

[0055]

[0056] In some embodiments, the network device 120 may directly indicate to the terminal device 110 whether the terminal device 110 needs to explicitly measure one or more component carriers. Such an indication may be explicitly signaled. Alternatively, such an indication may be sent via an existing measCycleScell. Table 2 shown below is an example signaling.

[0057] Table 2

[0058]

[0059]

[0060]

[0061] Alternatively, the network device 120 may indicate to the terminal device 110 whether it is necessary to explicitly measure the component carrier. Such an indication may be explicitly signaled, or may be performed by not configuring any measurement cycle (eg, measCycleScell) for the component carrier. Table 3 shown below is an example signaling.

[0062] Table 3

[0063]

[0064]

[0065] In some embodiments, if the network device 120 determines that the one or more component carriers are collocated with another component carrier, the collocation information may indicate that the one or more component carriers are collocated with the other component carrier. In other embodiments, if the network device 120 determines that the one or more component carriers are not collocated with another component carrier, the collocation information may indicate that the one or more component carriers are not collocated with the other component carrier. In some embodiments, the other component carrier may be a primary component carrier.

[0066] In an example embodiment, if the network device 120 determines that the one or more component carriers and the set of component carriers belong to the same collocation group, the collocation information may include an index of the one or more component carriers and an index of the set of component carriers.

[0067] As described above, the collocation information may also refer to an indication indicating whether the terminal device 110 needs to perform communication measurements on one or more component carriers.

[0068] In other embodiments, the concatenation information may also include measurement requirements of one or more component carriers, which will be described later.

[0069] Figure 3 A flow chart of method 300 is shown. Method 300 may be implemented at terminal device 110.

[0070] At block 310, the terminal device 110 receives collocation information of at least one component carrier and / or information of a first direction of a beam associated with at least one component carrier from the network device 110. In some embodiments, the collocation information may directly indicate whether the terminal device 110 needs to perform communication measurements on at least one component carrier or perform a reduced amount of communication measurements. For example, if the collocation information indicates that one or more component carriers are primary component carriers, the terminal device 110 may need to perform communication measurements on the one or more component carriers.

[0071] Alternatively, the collocation information may include an index of a collocated component carrier group including one or more component carriers. The terminal device 110 may determine the primary component carrier from the collocated group. For example, if there is a component carrier of a primary cell, the component carrier may be determined as the primary component carrier. If the component carriers in the collocated group are all component carriers of the SCell, the terminal device 110 may randomly determine the primary component carrier. Alternatively, the collocation information may indicate the primary component carrier determined by the network device 120.

[0072] At box 320, the terminal device 110 determines the requirement for communication measurement of one or more component carriers based on the collocation information and / or the information of the first direction of the beam associated with the one or more component carriers. In some embodiments, if the terminal device 110 determines that one or more component carriers are primary carriers or are not collocated with other primary carriers, the terminal device 110 determines to perform regular communication measurements on the one or more component carriers. For example, the terminal device 110 needs to measure RSRP and RSRQ and measure a minimum number of SSB-based beams on one or more component carriers. In another embodiment, the terminal device 110 may need to perform periodic neighboring cell searches on other component carriers. The primary component carrier can be determined by the terminal device 110 based on predetermined conditions. Alternatively, the primary component carrier can be indicated by the network device 120.

[0073] In other embodiments, if the terminal device 110 determines that one or more component carriers are collocated with other carriers and the one or more component carriers are not primary carrier components, the terminal device 110 determines to perform reduced communication measurements on the one or more component carriers. For example, the terminal device 110 may not need to measure the one or more component carriers at all. In this way, the measurement workload and power consumption of the terminal device 110 can be significantly reduced. Alternatively or additionally, if the collocation information indicates that the one or more component carriers have the same beam direction as other component carriers (e.g., primary component carriers), the terminal device 110 may also determine to perform reduced communication measurements on the one or more component carriers.

[0074] In another example, if the component carrier is not a primary carrier component, the terminal device 110 may determine to measure only a received signal strength indicator (RSSI). Alternatively or additionally, the terminal device 110 may determine not to measure RSPP / RSRQ measurements on one or more component carriers. In other embodiments, the terminal device 110 may determine that only one SSB needs to be measured per component carrier. In some embodiments, the terminal device 110 may determine not to perform neighbor cell searches on other in-band component carriers.

[0075] As described above, the requirements for communication measurements may be determined by the terminal device 110. Alternatively, the requirements for communication measurements may be configured by the network device 120.

[0076] At block 330, the terminal device 110 performs communication measurements on one or more component carriers based on the determined requirements. For example:

[0077] 1) The requirement specifies the terminal device measurement workload on a collocated CC (which may be different from a non-collocated CC). The network device 120 indicates the cells that may be assumed to be collocated (eg, via the collocatedWithServCell field as shown in the signaling above).

[0078] 2) The network device 120 indicates to the terminal device 110 whether the reduced measurement requirements apply to the CC (eg, via the presence of the field relaxedMeasurements in the above signaling example).

[0079] Based on these requirements, the terminal device 110 may perform measurements accordingly.

[0080] In one embodiment, the terminal device 110 may not need to measure any in-band CCs except the primary CC, which will significantly reduce the measurement workload and power consumption of the UE.

[0081] In some embodiments, if the collocation information indicates that one or more component carriers cannot be assumed to be collocated with any primary CC (e.g., via the absence of a collocation indication field or via setting the collocation id to be the same as the parent serving cell id), the terminal device 110 may perform measurements on the one or more component carriers accordingly. That is, the terminal device 110 may perform conventional measurements on one or more component carriers across multiple cells and beams.

[0082] As described above, if one or more component carriers are collocated with other component carriers and are not primary component carriers, the terminal device 110 may perform partial communication measurements on one or more component carriers. For example, the terminal device 110 may only provide layer 1 (L1) RSRP results without any layer 3 (L3) filtering. The terminal device 110 may also only provide cell detected / not detected information.

[0083] That is, it is not necessary to measure certain measurement parameters. In this way, the measurement workload and power consumption of the terminal device 110 can be significantly reduced.

[0084] In some embodiments, an apparatus for executing method 200 (e.g., network device 120) may include corresponding modules for executing corresponding steps in method 200. These modules may be implemented in any suitable manner. For example, it may be implemented by a circuit system or a software module.
