Description

Technical Field

[0001] The present application relates to a method, a chip and a terminal device for improving the measurement capability of a terminal device, and in particular to the measurement capability of the terminal device for measuring hetero-frequencies or hetero-systems. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) proposed that if the terminal device needs to perform inter-frequency or inter-system measurements, a simple way is to install two RF receivers in the terminal device to measure the frequency of the local cell and the frequency of the target cell respectively, but this will increase costs and cause interference between different frequencies. Therefore, 3GPP proposed the measurement gap (Gap) method, which is to reserve a part of time (i.e., the measurement Gap duration). During this time, the terminal device will not send or receive any data, but will adjust the receiver to the target cell frequency to perform inter-frequency measurements, and then switch to the current cell when the Gap time ends.

[0003] During the Gap measurement period, the terminal device will not send or receive any data, which may cause the user's data service to be interrupted or suspended, resulting in a poor user experience. Summary of the invention

[0041] Generally speaking, according to the provisions of the 3GPP protocol (for example, 3GPP TS36.214), when the terminal device is in a connected state (connection), the terminal device will periodically or event-basedly report the measured service cell and neighboring cell measurement reports to the network side. According to the measurement report, cell selection, reselection, switching and other actions can be completed; when the terminal device is in an idle state (idle), the terminal device will reside in the cell with the highest priority. In some possible embodiments, the priority of the cell's residence can be set by parameters such as the cell's signal quality, latency, packet loss rate, reference signal receiving power (PSRP), received signal strength indication (RSSI), and reference signal received quality (RSRQ).

[0042] like Figure 1 As shown, a network system is provided, comprising at least one terminal device 100 and at least one network device 1. In some embodiments, the terminal device 100 may be a mobile phone, a tablet computer, a handheld computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, and a personal digital assistant (PDA), a wearable device (such as a smart watch), an augmented reality (AR) or a virtual reality (VR) device, etc. This embodiment does not impose any special restrictions on the specific form of the device; the network device may be a base station (for example, a GSM base station, a NB base station, an eNB base station, a NR base station, etc.), a server, a network element, etc. This embodiment takes an LTE (Long Term Evolution Advanced, "LTE") network system as an example, that is, the network device and the user equipment are devices supporting LTE functions. This embodiment can be extended to other network systems.

[0043] The network device 1 is a 4G base station supporting LTE function, i.e., eNB. According to the radio coverage of the eNB, it can usually include at least one service cell, i.e., service cell 1. A cell is an area that provides wireless communication services to users and is the basic component unit of a wireless network. The eNB can also be divided into multiple cells, each of which can use a different wireless carrier, and each wireless carrier uses a certain carrier frequency. This application does not facilitate description, each cell corresponds to a network device, but it is not limited. A network device can also correspond to multiple different cells, including a primary cell and multiple secondary cells.

[0044] In wireless technology, the concept of CA (Carrier Aggregation) is introduced. Simply put, it can aggregate multiple carriers into a wider spectrum, and it can also aggregate some discontinuous spectrum fragments together. It can be understood that carrier aggregation (CA) is to aggregate two or more component carriers (CC) together to support a larger transmission bandwidth. In order to efficiently utilize fragmented spectrum, CA supports multiple aggregation methods: CCs with the same or different bandwidths; CCs that are adjacent or non-adjacent in the same frequency band; CCs in different frequency bands.

[0045] Each carrier unit CC corresponds to an independent cell, which can be divided into the following types of cells in the CA scenario:

[0046] Primary Cell (Pcell): The primary cell is a cell operating on the primary frequency band. The terminal device performs the initial connection establishment process or starts the connection reestablishment process in this cell. During the handover process, this cell is indicated as the primary cell;

[0047] Secondary Cell (Scell): A secondary cell is a cell operating on a secondary frequency band. Once an RRC connection is established, the secondary cell may be configured to provide additional radio resources;

[0048] Serving Cell: A terminal device in the RRC_CONNECTED state. If CA is not configured, there is only one Serving Cell, namely PCell. If CA is configured, the Serving Cell set consists of PCell and SCell.

[0049] Pcell and Scell ​​are user-level concepts for CA users. The carrier that the user initially accesses is the Pcell of the CA user. The primary cell is the cell that works on the primary frequency band. The terminal device performs the initial connection establishment process in this cell, or starts the connection reestablishment process. During the handover process, the cell is indicated as the primary cell; the secondary cell is the cell that works on the secondary frequency band. Once the RRC (Radio Resource Control, RRC) connection is established, the secondary cell may be configured to provide additional radio resources (see Section 3.1 of 36.331).

[0050] like Figure 2 As shown, a schematic diagram of a terminal device reporting measured network quality is provided. The measurement report (MR, Measurement Report) is an important function of the LTE system. The measurement results reported by the physical layer can be used by the wireless resource control sublayer in the system to trigger events such as cell selection / reselection and switching, and can also be used for network neighbor maintenance, SCG addition and other functions. The LTE MR report can also include reference signal received power, reference signal received quality, eNB received interference power, eNB antenna arrival angle, terminal device transmit power margin, uplink packet loss rate, downlink packet loss rate, uplink signal-to-noise ratio, PRB granularity eNB received interference power, etc. Based on MR, the coverage of the entire network, interference, uplink high transmit power, and terminal device location can be analyzed. For example, the eNB received interference power RIP in MR can be used to statistically analyze the interference situation of the entire network and locate high-interference cells. In the connected state, network measurement usually has the following purposes:

[0051] 1. Pcell switching: When the network quality of the Pcell where the terminal device resides meets the preset conditions, for example, the signal quality of the current cell is lower than the threshold, the A2 event (Event A2) is triggered, and the network allocates a different frequency point to measure the network quality of the neighboring cell. The network does not need to indicate the same frequency neighboring cell measurement, and the terminal device can measure at any time in the connected state.

[0052] 2. Adding Scell: If the measured cell meets the A4 event, that is, EvenA4, the triggering condition of the A4 event can be understood as when the measured cell is greater than a certain threshold configured by the network, the network can configure Scell ​​for the user, and the user can exchange data with the core network through Pcell and Scell ​​cells. Figure 1As shown, when the terminal device resides in service cell 1, service cell 1 is Pcell. After adopting CA technology, the terminal device also needs to measure the network parameters of the neighboring cells (such as service cell 2 or service cell 3). When the measured network parameters of the neighboring cells meet a certain threshold value configured by the network side, that is, the trigger condition of the A4 event is met, the network side can configure the Scell ​​cell for the terminal device, thereby realizing high-bandwidth data transmission.

[0053] 3. Use measurement reports to perform network system operation and maintenance, automatic configuration of inter-frequency adjacent cells, and other operations.

[0054] 4. In some special scenarios, such as LTE dual connection Eutran-dual connection (EE-DC) and EN-DC dual connection, the terminal device also needs to measure the target cell of the dual connection, such as measuring NR (5G cell or LTE cell.

[0055] If the terminal device does not have the no Gap measurement capability for the relevant frequency point (it can be understood that the terminal device must require the network to allocate a Gap for measurement), the network will allocate the following two types of Gap for measurement (before 3GPP release 14). Table 1 shows the two different types of Gap specified in the protocol, as shown in the table:

[0056]

[0057] It can be seen that the length of the Gap is 6ms, the period is 40ms or 80ms, and it is used to measure the network parameters of cells with different frequencies or systems. Generally speaking, due to the existence of the Gap, the terminal device cannot send or receive data at this time, that is, when the terminal device measures the network quality of the neighboring cell according to the Gap allocated by the network side, the terminal device usually cannot send or receive data. Figure 1 Take the system shown in FIG. 1 as an example, that is, when the current network side allocates Gap to measure the neighboring cell (serving cell 2 or serving cell 3), data cannot be sent or received through serving cell 1; or Figure 1 Taking the system shown as an example, the current terminal device supports CA capability, for example, service cell 1 is Pcell, the frequency band is A1, service cell 2 is auxiliary cell, the frequency band is A3, and the terminal device can obtain the A1+A3 frequency band capability through CA. If the current Gap is used to measure the neighboring cell (for example, service cell 3), data cannot be sent or received through service cell 1 or service cell 2.

[0058] like Figure 3As shown, a typical Gap diagram is provided. For example, Gap needs to be allocated because the LTE scheduling / feedback duration is at least 4ms. Data cannot be sent or received within at least 4ms before and after the Gap measurement duration, that is, data cannot be transmitted for 10ms for uplink and downlink data respectively. If the measurement period is 40ms, at least 10 / 40=25% scheduling opportunities are lost, that is, 25% performance is lost.

[0059] Terminal equipment usually consists of antenna, RF front end module (FEM), RF processing unit (RFIC), baseband integrated circuits (BBIC), etc., where RFIC represents the RF channel capability of the terminal equipment, for example, Rx1, Rx2...RxN represent the receiving channel of a certain frequency band (such as the main receiving channel or the diversity receiving channel). Figure 4 As shown, a typical terminal device 100 is provided, including a baseband processor 103 , a radio frequency circuit 102 , and an antenna 101 .

[0060] like Figure 5 As shown, a typical terminal device schematic diagram is provided; the terminal device 100 includes a baseband processor, a radio frequency processing unit (RFIC), a power amplifier (PA), a filter, a duplexer and an antenna. The chip platform, the radio frequency front end and the antenna constitute the wireless communication module of the terminal. Among them, the chip platform includes a baseband chip, a radio frequency chip and a power management chip. The baseband chip is responsible for the physical layer algorithm, the processing of high-level protocols and the implementation of multi-mode interoperability; the radio frequency chip is responsible for the mutual conversion between radio frequency signals and baseband signals; the radio frequency front end module is the only way to connect the radio frequency processing unit and the antenna, such as Figure 1 It mainly includes: power amplifier (PA), filter (Filter), duplexer or multiplexer (Duplexer or Mult iplexer), low noise amplifier (LNA) and switch (Switch) or antenna tuning module (ASM), etc. In the RF front-end architecture of some terminals, devices such as diplexer (Diplexer) and connector (Coupler) are added after the antenna switch.

[0061] But generally speaking, whether the measurement capability of Gap is needed for inter-frequency or inter-system measurement is often determined by the number of receiving channels of the radio frequency processing unit RFIC. In this embodiment, it is assumed that the RF front-end FEM (including power amplifier, filter, duplexer, etc.) of the terminal equipment supports 3 frequency bands (B1, B3, B7), and the RFIC has 4 receiving channels (Rx1, Rx2, Rx3, Rx4), and the BBIC can simultaneously support the service cell data reception and inter-frequency measurement. Assuming that the frequency of the inter-system and the service cell frequency also support CA combination, the BBIC also supports simultaneous service cell data reception and inter-system measurement. As shown in Table 2, the inter-frequency measurement capability of the terminal equipment is shown (for example, through the command InterFreq NeedforGaps), hereinafter referred to as "measurement capability" or "whether Gap capability needs to be allocated" or "Gap capability", "Gap measurement capability", etc.:

[0062]

[0063] As shown in Table 2, 1A, 3A, and 7A indicate carrier units of different frequency bands (band 1, band 2, and band 3, respectively). Each frequency band occupies two receiving channels of the terminal device, where [1A] indicates that four receiving channels are occupied, and T represents the need to allocate a Gap. It can be seen that when the terminal device is a CA combination or 4Rx, inter-frequency measurement requires the network to allocate a Gap. The specific description is as follows: The current terminal device is sending and receiving data on the 1A frequency band (for example, the terminal device resides in the first cell), where the 1A frequency band occupies two receiving channels (for example, Rx1, Rx2). At this time, the network allocates Gap measurement, and only needs to use Rx3 and Rx4 channels to measure the neighboring cells. The network side does not need to allocate Gap. However, when the terminal device is in the [1A] frequency band, that is, it occupies four channels, Rx1, Rx2, Rx3, and Rx4. At this time, the network side needs to allocate Gap to measure the network quality of the neighboring cells. When the four channels of the terminal device are all occupied, only the data transmission and reception of the terminal device in the serving cell is suspended, and any two channels (for example, Rx1, Rx2) are allocated to the terminal device to measure the neighboring cells. Similarly, when the terminal device uses CA capabilities to send and receive data, for example, in the 1A+3A scenario, a total of 4 channels are occupied for neighboring cell measurement. Since the channel resources of the current terminal device are already full, the network needs to allocate Gap to measure the network instructions of the neighboring cells, causing the current service to be interrupted.

[0064] In the above embodiments, when the network allocates heterogeneous frequencies or heterogeneous systems for the terminal device to monitor and measure, in this case, since the terminal device cannot send and receive data when measuring the neighboring cell, it will cause problems such as suspension and delay in the user's data transmission and reception, and the user experience is not good. It is worth noting that in this application, heterogeneous frequencies can be frequency bands with different central frequencies, which can be understood as heterogeneous frequencies, and heterogeneous systems refer to systems with different network standards, which can be understood as heterogeneous systems, such as 3G and 4G.

[0065] Based on this, the present application also provides another embodiment, where the terminal device has the ability to simultaneously receive the frequency point where the heterogeneous frequency or heterogeneous system is located and the frequency point of the serving cell, then the network does not need to allocate a gap. In this case, the terminal device can perform heterogeneous frequency or heterogeneous system measurements without interrupting communication with the serving cell.

[0066] like Figure 6 As shown, a method for allocating Gap according to the measurement capability of a terminal device is provided. In this embodiment, when the network allocates Gap for inter-frequency measurement, it is determined whether Gap needs to be allocated according to the measurement capability of the terminal device. This is to solve the problem of how to perform neighboring cell measurement without allocating Gap when the terminal device is in a connected state and the receiving channel of the terminal device is limited.

[0067] Step 601: The terminal device registers to the first cell and reports the Gap measurement capability.

[0068] Generally speaking, if a terminal device wants to obtain services, it needs to register with the network. This registration process is called Attach (taking the LTE system as an example). The terminal device can report the measurement capability of the terminal device during the Attach process. According to the protocol, for example, the parameters that identify the measurement capability of the current terminal device may be interFreqNeedForGaps and interRAT-NeedForGaps, which are described in the protocol as "Indicates need for measurement Gaps when operating on the E UTRA band given by the entry in bandListEUTRA or on the E-UTRA band combination given by the entry in bandCombinationListEUTRA andmeasuring on the E UTRA band given by the entry in interFreqBandList." and "Indicates need for DL ​​measurement Gaps when operating on the E UTRA bandgiven by the entry in bandListEUTRA or on the E-UTRA band combination givenby the entry in bandCombinationListEUTRA and measuring on the inter-RAT bandgiven by the entry in the interRAT-BandList".

[0069] For ease of description, Table 2 can be understood as the measurement capability of the current terminal device. It is worth noting that Table 2 only provides a form of expression of the measurement capability of a terminal device. As shown in Table 2, the content reported by the terminal device includes but is not limited to the CA capability of the terminal device, such as supporting the following CA combinations: CA_1A-3A; CA_1A-7A; CA_1A-1A; CA_3A-1A; CA_3A-3A; CA_3A-7A; CA_7A-3A. In some possible designs, CA combinations of multiple frequency bands may also be supported, such as CA_1A-3A-5A. The capabilities reported by the terminal device to the network side also include whether the CA combination supported by all terminal devices or the supported frequency bands need to allocate Gap capabilities, etc. Specifically: InterFreqNeedForGaps is used to identify whether a certain CA combination or a service cell needs a Gap for single-band measurement of different frequency points, and interRAT-NeedForGaps is used to identify whether a certain CA or service cell needs a Gap for single-band measurement of different systems. O,1 bits can be used to identify whether a Gap is needed, and the Boolean function BOOLEAN can also be used to identify. In some embodiments, the content reported by the terminal device also includes the multi-input and multi-output capabilities of each cell or CA. For example, in the cell corresponding to the A1 frequency band, the number of receiving channels of the terminal device is 2. When implementing, it can be the following way:

[0070] bandEUTRA-r10:3,0x26;

[0071] supportedMOMO-CapabilityDL-r10:twoLayers(0,0x0) indicates that in band 3, the number of layers supporting multi-input and multi-output is 2, supportedMOMO-CapabilityDL-r10:fourLayers(0,0x0) indicates that the number of layers supporting multi-input and multi-output is 4 in the current frequency band. In some embodiments, the number of layers is the number of receiving channels of the corresponding terminal device.

[0072] Table 2 shows the measurement capabilities of 11 CA combinations or frequency bands, that is, whether a Gap needs to be allocated. For example, in the case of 1A+3A, since the CA combination needs to occupy 4 receiving channels, and the current terminal device has 4 channels, that is, there are no extra channels to measure the neighboring cells, the network side needs to allocate a Gap. However, Table 2 only shows the ability to allocate a Gap for different frequency bands. Whether a Gap needs to be allocated for measuring different frequency systems can also refer to the capabilities reported by the terminal device, as shown in Table 3:

[0073]

[0074] Table 3 shows a schematic diagram of whether the terminal device needs to allocate Gap capability when measuring an inter-frequency system, that is, it shows whether the Gap capability needs to be allocated if the cells belong to different network systems under the CA combination. For example, taking CA_1A+3A as an example, when inter-system measurement is required, for example, the trigger condition may be an A4 event or initiated by the network, and according to the inter-frequency measurement capability of the terminal device, the network needs to allocate Gap to the terminal device for inter-frequency measurement.

[0075] The terminal device also needs to report the supported CA capabilities and the multi-input and multi-output capabilities (number of layers) of each cell or CC and the corresponding measurement capabilities. The network side can configure the corresponding number of layers according to the receiving channel capabilities of the terminal device in each cell or CC. The network side determines whether a gap needs to be allocated based on the measurement capability reported by the terminal device, and determines various different CA combinations based on the CA capabilities uploaded by the terminal device.

[0076] Step 602: The network side determines whether a Gap needs to be allocated based on the triggering condition and the measurement capability reported by the terminal device. If a Gap does not need to be allocated based on the measurement capability reported by the terminal device, step 603 is executed; if a Gap needs to be allocated based on the measurement capability reported by the terminal device, step 604 is executed.

[0077] Generally speaking, the establishment process of the secondary cell SCell mainly includes: the terminal device initiates the radio resource control layer (RRC) connection process in the primary cell PCel l, and the network side determines whether to configure the measurement Gap based on the measurement capability reported by the terminal device. If the terminal device needs Gap for inter-frequency measurement, the network side sends measurement control information (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) and configures the measurement Gap period and subframe offset parameters; if the terminal device does not need to start Gap for measurement, the network side skips the configuration of the measurement Gap and directly sends the measurement control information.

[0078] Step 603: When the network side determines that no Gap is needed for the terminal device based on the measurement capability reported by the terminal device, the network side configures the measurement control messages such as frequency, measurement threshold, measurement bandwidth, measurement parameters, and measurement report parameters in the radio resource control layer reconfiguration message (RRC Connection Reconfiguration), and does not allocate Gap related information.

[0079] When the terminal device measures an inter-frequency point that meets the threshold of the A4 event (A4 Event), the A4 event is reported. The network side detects the cell that meets the A4 measurement conditions reported by the terminal device. If there is one in the same cell set, it sends an RRC reconfiguration request message RRC Reconfiguration Req to the terminal device to configure it as the Scell ​​of the CA terminal device. According to the protocol, the A4 event is defined as the quality of the inter-frequency neighboring cell is higher than a certain threshold. The trigger condition is Mn+Ofn+Ocn-Hys>Thresh, where Mn: inter-frequency cell measurement result; Ofn: frequency offset, the specific frequency offset of the neighboring cell frequency; Ocn: cell offset, the specific cell offset of the cell; Hys: inter-frequency switching amplitude hysteresis, event A4 hysteresis parameter, determined by the parameter InterFreqHoA4Hyst; Thresh: added as the trigger threshold of the Scell, usually set to -94dbm, -100dbm, -105dbm based on RSRP. Figure 1 Taking the system shown in the figure as an example, the RSRP of the current main serving cell is -92bdm, and the RSRP of the inter-frequency cell is -88bdm. If the threshold value of A4 is set to -91dbm, cell 2 can be configured as Scell.

[0080] Step 604: The network side sends measurement control information (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) and configures the measurement Gap period and subframe offset according to the measurement capability reported by the terminal device.

[0081] Generally speaking, the network side periodically sends measurement control information and configures the Gap period to the terminal device to measure the information of hetero-frequency or hetero-system cells.

[0082] Step 605: Further, in this embodiment, when the terminal device receives the measurement control information and parameters such as the Gap period sent by the network side, the terminal device evaluates whether it can achieve the ability to measure the neighboring cells without allocating Gap by reducing the receiving channels of the current cell (for example, reducing the number of layers). For example, if the cell frequency band of the current Pcell is configured as 4 layers by the network, the CC of the current Pcell occupies 4 channels, and the network side needs to perform inter-frequency measurement in order to increase the Scell, according to whether the Gap capability needs to be allocated as reported by the terminal device, it is confirmed that the Gap needs to be allocated at present. In this embodiment, in order to avoid service performance such as data delay and interruption, the terminal device evaluates whether it can achieve the measurement capability without allocating Gap by reducing the Pcell receiving channels, that is, changing the receiving capability of 4 layers of the Pcell frequency band to the receiving capability of 2 layers, then the terminal can modify the Pcell occupying 4 receiving channels to occupying 2 receiving channels, and use the released 2 channels to measure the network quality of the neighboring cells, that is, the purpose of measuring the neighboring cells without allocating Gap can be achieved.

[0083] Step 606: When the terminal device evaluates that the number of layers of certain CCs can be reduced to achieve the capability of measuring neighboring cells without allocating Gap, auxiliary information can be reported for the network side to reconfigure not allocating Gap.

[0084] For example, the layer is reduced through the terminal device AssistanceInformation message. The description of the terminal device AssistanceInformation message in the protocol is as follows:

[0085] 1.if the UE prefers a configuration primarily optimized for powersaving:

[0086] 2>set powerPrefindication to lowPowerConsumption;

[0087] 2.else

[0088] 2>start or restart T340 with the timer val UE set to thePowerprefindicationTimer

[0089] 2>set PowerprefindicationTimer to normal;

[0090] The UE shall submit the UE AssistanceInforamation message to lowerlayers for transmission.

[0091] After receiving the auxiliary information reported by the terminal device, the network side reconfigures the number of layers of the primary cell Pcell. The network side determines not to allocate a Gap to the terminal device based on the configured number of layers and the measurement capability of the terminal device.

[0092] Step 607: Based on the measurement capability reported by the terminal device, if the network side determines that even by reducing the number of layers of some CCs, it is still impossible to avoid allocating Gap, then according to the existing process, the network side can send down measurement control (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) and configure the measurement Gap period and subframe offset.

[0093] Step 608: The terminal device performs measurement according to the measurement control sent by the network and reports the measurement result.

[0094] Step 609: The network side configures the secondary cell according to the measurement result reported by the terminal device.

[0095] like Figure 7 As shown, another method for allocating Gap according to the terminal device capability is provided. In this embodiment, when the network allocates inter-frequency measurement, it is determined whether Gap is needed according to the measurement capability of the terminal device. This is to solve the problem of how to perform neighboring cell measurement without allocating Gap when the terminal device receiving channel is limited in the connected state.

[0096] Step 701: The current terminal device serving cell is a CA combination, and resides in the primary cell Pcell and the secondary cell Scell. Figure 1 In the system shown, the terminal device 100 obtains wireless resources through serving cell 1 and serving cell 2. As shown in Table 3, the terminal device can obtain unlimited resources through the following CA combinations, such as the following CA combinations: CA_1A-3A; CA_1A-7A; CA_1A-1A; CA_3A-1A; CA_3A-3A; CA_3A-7A; CA_7A-3A;

[0097] Step 702: The current system meets the triggering condition;

[0098] In this embodiment, the triggering condition may be, for example, the A2 event specified in the protocol, that is, the signal quality of the current serving cell (such as serving cell 1 or serving cell 2) is lower than a predetermined threshold, that is, Ms + Hys < Thresh, where Ms is the measurement result of the serving cell; Hys is the inter-frequency A1 or A2 amplitude hysteresis; Thresh is the A2 inter-frequency threshold based on a certain event, and A2 is used to initiate inter-frequency or inter-system measurements; in a possible embodiment, the network side needs to actively initiate the requirement for measuring neighboring cells, and it may also be a triggering condition such as the mobility measurement of the terminal device.

[0099] Step 703: The network side determines whether to allocate a corresponding Gap according to the triggering condition and the capabilities reported by the terminal device. If no Gap needs to be allocated, go to Step 704; if a Gap needs to be allocated, go to Step 705.

[0100] When the network side needs to measure neighboring cells according to the event reported by the terminal device (such as the A2 event) or when the network side needs to actively measure neighboring cells, it needs to determine whether to allocate a Gap for measurement according to the capabilities reported by the terminal device. In this application, it is further determined whether the terminal device can be evaluated to achieve measurement without a Gap by releasing some Scells. As shown in Table 4, after the network side receives the measurement capabilities reported by the terminal device, it also needs to consider whether to achieve the purpose of not allocating a Gap by releasing the Scell, so that the terminal device will not experience interruption or delay.

[0101]

[0102] Specifically, as shown in Table 4, for example, when the current terminal device is in the CA_1A + 3A combination, according to the measurement capabilities reported by the terminal device, if the network side needs to measure the information of inter-frequency neighboring cells, the network side needs to allocate a Gap. However, when the terminal device can be evaluated to be able to measure inter-frequency neighboring cells by configuring secondary cells, it can prompt the network side to configure secondary cells and re-combine CA so that the network does not allocate a Gap, and it is determined that the terminal does not need a measurement gap when measuring the same target frequency point, and the measurement configuration does not include gap-related configuration information. For example, when the network side needs to measure the inter-frequency cell frequency point of band 7, by prompting the network to configure Scell (3A), at this time the terminal device only transmits and receives data on band 1, then at this time the terminal device can measure the inter-frequency cell on band 7 without a Gap.

[0103] Step 704: When the network side determines that no Gap is needed according to the capabilities reported by the terminal device, the network side configures measurement control messages (frequency point information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) in the RRC connection reconfiguration message without allocating Gap-related information.

[0104] Step 705: If the terminal device needs to start the Gap, the network side sends measurement control information (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.), measurement Gap period and subframe offset in the RRC connection reconfiguration message;

[0105] Step 706: The terminal device further determines whether it is possible to achieve the purpose of not needing to allocate Gap measurement by deconfiguring CA or deactivating CA. If it is determined that it is possible, step 707 is executed, otherwise step 708 is executed.

[0106] Step 707: The terminal device can prompt the network to configure the secondary cell CC so that the network measurement does not need to allocate a Gap. Specifically, the terminal device can actively report the A2 event of the secondary cell Scell, and the network side completes the Scell ​​deconfiguration action. After the network side deconfigures the Scell, the network side reconfigures a new CA combination to determine whether the measurement of the heterofrequency point has the ability to not allocate a Gap. The network side reconfigures the CA and measurement configuration information based on the A2 event reported by the terminal device and the measurement capability reported by the terminal device. Under the new CA combination, it is determined that the terminal does not need to measure a gap when measuring the same target frequency point, and the measurement configuration does not include gap-related configuration information, wherein the measurement configuration information does not include gap-related configuration information.

[0107] Specifically, after the network side receives the A2 event actively reported by the terminal device, the network side configures the secondary cell by sending an RRC reconfiguration message. The terminal device releases the receiving channel of the secondary cell and sends a response message to the network device to indicate that the second cell has been released. Further, the network side resends the measurement control information, in which the Gap information is not configured.

[0108] Step 708: The terminal device evaluates that it is unavailable and prompts the network to configure the auxiliary CC, so that the network measurement does not need to allocate a Gap, and the terminal device has the ability to measure the inter-frequency point without allocating a Gap. The terminal device then measures the inter-frequency cell or inter-system allocated by the network according to the Gap allocated by the network.

[0109] Step 709: The terminal device performs measurement according to the measurement control sent by the network and reports the measurement result.

[0110] Step 710: The network side performs cell switching based on the measurement results reported by the terminal device.

[0111] like Figure 8As shown, a method for allocating gaps according to terminal equipment capabilities is provided, which actively reduces the layer specifications of certain carrier units in the CA combination, so that the terminal equipment has the ability to measure different frequencies and systems without allocating gap measurement networks.

[0112] Step 801: The terminal device resides in at least two cells through CA combination, and one of the cells requires the network side to configure 4 layers capabilities;

[0113] The current terminal device serving cell is a CA combination, residing on the primary cell Pcell and the secondary cell Scell. Figure 1 In the system shown, the terminal device 100 obtains wireless resources through service cell 1 and service cell 2, where either cell has a 2Rx receiving capability. For example, when the terminal device reports that it needs to occupy 2 receiving channels in the 1A frequency band, the network side allocates the corresponding number of layers according to the capacity of occupying the receiving channels during configuration.

[0114] Step 802: The system meets the triggering condition, such as the A2 event reported by the terminal device or the network instructs the terminal device to monitor other out-of-frequency cells;

[0115] Step 803: The network side determines whether a Gap is required to be allocated to the terminal device for measuring neighboring cell information according to the Gap measurement capability reported by the terminal device. If it is determined that a Gap does not need to be allocated, step 804 is executed. If it is determined that a Gap needs to be allocated, step 805 is executed.

[0116] Step 804: When the network side determines that a Gap is not required based on the capability report of the terminal device, the network side configures measurement control messages such as frequency points in the radio frequency control reconfiguration RRC re-configuration message, and does not allocate related information such as the Gap period.

[0117] Step 805: If the terminal device needs to start the Gap, the network side sends measurement control information (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) and configures the measurement Gap period and subframe offset;

[0118] Step 806: When the terminal device evaluates that the number of layers of some cell CCs can be reduced to achieve the capability of measuring neighboring cells without allocating gaps, step 807 is executed; otherwise, step 808 is executed.

[0119] Step 807: The network side allocates Gap to measure these inter-frequency points, and the terminal device evaluates whether it can achieve the capability of not allocating Gap measurement by releasing 1layer of some CCs. If the Gap measurement capability can be achieved by releasing 1layer. When the terminal device evaluates that it can achieve the capability of measuring neighboring cells without allocating Gap by reducing the number of layers of some CCs, it can report auxiliary information for the network side to stop allocating Gap.

[0120] For example, the layer data can be reconfigured through the terminal device AssistanceInformation message. The description of the terminal device AssistanceInformation message in the protocol is as follows:

[0121] 1.if the UE prefers a configuration primarily optimized for powersaving:

[0122] 2>set powerPrefindication to lowPowerConsumption;

[0123] 2.else

[0124] 2>start or restart T340 with the timer val UE set to thePowerprefindicationTimer

[0125] 2>set PowerprefindicationTimer to normal;

[0126] The UE shall submit the UE AssistanceInforamation message to lowerlayers for transmission.

[0127] After the network side receives the auxiliary information reported by the terminal device, it reconfigures the measurement information, such as reconfiguring the number of layers of the main cell Pcell. The network side determines not to allocate Gap to the terminal device based on the configured number of layers and the measurement capability of the terminal device. Specifically: Pcell or Scell ​​occupies only one receiving channel, and the measurement frequency also occupies only one channel. A channel is released within a certain carrier unit. The heterodyne frequency points allocated by the network are measured through the released channel and a front-end receiving antenna. Another antenna is used to send and receive data for this carrier unit. At this time, because Pcell only has one receiving channel for reception, the corresponding receiving capability will decrease, and the channel quality indicator (Channel Quality Indicator, CQI) will be fed back based on the actual receiving capability.

[0128] Step 808: Based on the measurement capability reported by the terminal device, if the network side determines that even by reducing the number of layers of some CCs, it is still impossible to avoid allocating Gap, then according to the existing process, the network side can send down measurement control (frequency information, measurement bandwidth, measurement parameters, measurement report parameters, etc.) and configure the measurement Gap period and subframe offset.

[0129] Step 809: The terminal device performs measurement according to the measurement control sent by the network and reports the measurement result.

[0130] Step 810: The network side configures the secondary cell according to the measurement results reported by the terminal device.

[0131] like Fig. 9 As shown, a method for allocating Gap according to the terminal device capability is also provided. The terminal device can achieve the measurement capability of measuring hetero-frequency or hetero-system by actively reducing the receiving specification, and actively reports the updated Gap measurement capability when the terminal device is registered. When the network allocates hetero-frequency and hetero-system measurement, it reports whether to allocate Gap measurement according to the terminal device capability.

[0132] The network side allocates the measurement frequency without dividing the measurement interval Gap. The terminal device determines whether the frequency allocated by the network and the frequency of the serving cell have the ability to receive simultaneously. If there is no ability to receive simultaneously, the terminal device actively reduces the receiving specification through the PHY and MAC layer methods, which may be adopted in the following ways:

[0133] 1) Deactivate the secondary cell SCC; 2) The terminal device actively reduces the reception specifications of certain carriers, for example, from 4Rx to 2Rx, and reports the measurement value according to the reception capability of 2Rx; or 3) Short-term preemption and other methods, so that the terminal device can measure the heterogeneous frequency or heterogeneous system assigned by the network without Gap measurement. 4) The terminal device actively changes from 2Rx to 1Rx in certain carrier units, and reports the measurement value according to the reception capability of 1Rx, releasing the channel for corresponding heterogeneous frequency or heterogeneous system measurement.

[0134] Assuming that the front-end FEM of the terminal device supports 3 bands, the RFIC has 4 channels, and the BBIC can support both the service cell transmission and reception and the inter-frequency measurement. Assuming that the frequency of the inter-system and the service cell also support CA combination, the BBIC also supports the service cell transmission and reception and the inter-system measurement. For simplicity, the following table only lists the inter-frequency measurement of LTE. The following CA combinations are supported at the same time (1A represents the band1 frequency point 20MHz bandwidth, which is 2Rx); [1A] represents band1 is 4Rx.

[0135] Assume that the CA combinations can be supported: CA_1A-3A; CA_1A-7A; CA_1A-1A; CA_3A-1A; CA_3A-3A; CA_3A-7A; CA_7A-3A. Assume that the inter-frequency measurement capability of the terminal device depends entirely on the CA capability. Then the inter-frequency measurement capability is reported as follows: T represents the need for Gaps; F represents the need for Gaps. As shown in Table 5:

[0136]

[0137] After the terminal device reports its capability, when the network allocates inter-frequency measurement, it determines whether a Gap is needed based on the measurement capability of the terminal device. As can be seen from the above table, when the terminal device is a CA combination or 4Rx, inter-frequency measurement requires a Gap due to the capability limitation of the terminal device. If the terminal device can reduce the receiving specification or configure the secondary cell CC so that the terminal device does not need to allocate a Gap, the terminal device actively reports the updated measurement capability. As shown in Table 6, the corresponding reported Gap measurement capability is:

[0138]

[0139] It can be seen from the table that the Gap measurement capability of the terminal equipment is greatly enhanced. In various CA combinations, Gap-free measurement can be achieved by reducing the number of channels for receiving data and removing auxiliary cells.

[0140] Furthermore, the service cell of the terminal device can further reduce the receiving antenna to achieve the gap measurement capability without allocation. For example, assume that B7 and B1 do not have CA capability. B7 can only use the main channel without the diversity channel. Then the terminal device uses the diversity channel to measure the frequency point capability of B3. Similarly, the service cell B7 measures other frequency points of B7. As shown in Table 7:

[0141]

[0142] The specific method is as follows:

[0143] Step 901: The terminal device reports updated capabilities;

[0144] In this application, as shown in Table 5, when the terminal device is camping in a cell, it will report the CA capabilities supported by the terminal device and the multiple input multiple output capabilities (number of layers) of each cell or CC and whether the Gap measurement capability is required in different cells;

[0145] In Table 6, the measurement capability of whether a Gap needs to be allocated in the table is updated. On the one hand, the terminal device determines whether the receiving specification of the terminal device can be reduced to achieve the capability of not allocating a Gap. For example, Table 5 shows the original Gap measurement capability of the terminal device. In most scenarios, the inter-frequency measurement requires the network side to allocate a Gap. For example, when the terminal device is at the [1A] frequency point, it currently needs to send and receive data through 4Rx, and the network needs to allocate a Gap to measure the inter-frequency cell; the terminal device further evaluates that it can achieve the purpose of not allocating a Gap by reducing the receiving specification, as shown in Table 6, and the terminal device reports the updated capability, and the network does not need to allocate a Gap to measure the inter-frequency cell; for another example, as shown in Table 5, the terminal device is in the CA_1A+3A scenario, and currently needs to send and receive data through 4Rx, and the network needs to allocate a Gap to measure the inter-frequency cell. The terminal device further evaluates that it can achieve the purpose of not allocating a Gap by reducing the receiving specification, as shown in Table 6, and the terminal device reports the updated capability, and the network does not need to allocate a Gap to measure the inter-frequency cell. On the other hand, the terminal device can also perform area measurement by deconfiguring or deactivating the secondary cell. If the current terminal is in the CA_1A+3A scenario and currently needs to send and receive data through 4Rx, the network needs to allocate a Gap to measure the inter-frequency cell. The terminal device further evaluates that it can achieve the purpose of not needing to allocate a Gap by deactivating the CC of the secondary cell. As shown in Table 6, the terminal device reports the updated capability and does not need the network to allocate a Gap to measure the inter-frequency cell.

[0146] In some embodiments, as shown in Table 7, it is assumed that B7 and B1 do not have CA capabilities. B7 can use only the main channel without the diversity channel. Then the terminal device uses the diversity channel to measure the frequency capability of B3. Similarly, the service cell B7 measures other frequencies of B7.

[0147] Step 902: The system meets the triggering condition, such as the A2 event reported by the terminal device or the network instructs the terminal device to monitor other out-of-frequency cells;

[0148] Step 903: The network side determines whether a Gap is required to be allocated to the terminal device for measuring neighboring cell information according to the Gap measurement capability reported by the terminal device. If it is determined that a Gap does not need to be allocated, step 907 is executed. If it is determined that a Gap needs to be partially allocated, step 904 or step 906 is executed.

[0149] Step 904: The terminal device reduces the current data receiving channel specification.

[0150] For example, in the current scenario of CA_1A+3A, where 1A occupies receiving channels Rx1 and Rx2, and 3A occupies Rx3 and Rx4, neighboring area measurement can be performed by reducing the current data receiving channel specification, specifically, using Rx2 and Rx3 for neighboring area measurement.

[0151] In the implementation of this embodiment, the terminal device reduces the multi-input and multi-output capability of the terminal device, and can reconfigure the layer data by configuring the AssistanceInformation message to the network side; in a possible design, the terminal device can reduce the multi-input and multi-output capability by closing the number of its own receiving channels. It can be understood that in this case, the network side still periodically allocates Gap-related information to the terminal.

[0152] Step 905: The terminal device reports updated CQI and rank indication parameters.

[0153] Since the receiving channel rules of the terminal equipment are lowered, correspondingly, in order to avoid a decrease in the receiving service capability, the corresponding measurements, such as rank, CQI, etc., can be lowered. The terminal equipment uses the released receiving capability to measure different frequencies or systems.

[0154] Step 906: The terminal equipment area suspends data transmission and reception of the secondary cell;

[0155] Currently in the CA_1A+3A scenario, where 1A occupies receiving channels Rx1 and Rx2, and 3A occupies Rx3 and Rx4, neighbor cell measurement can be performed by deconfiguring or deactivating the secondary cell, specifically, using Rx2 and Rx3 for neighbor cell measurement.

[0156] In the implementation of this embodiment, the terminal device reduces the transmission and reception of data in the secondary cell by suspending the transmission and reception of data in the secondary cell, and the secondary cell may be deactivated or deconfigured through the RRC reconfiguration message of the terminal device; in a possible design, the terminal device may suspend the transmission and reception of data in the secondary cell. It can be understood that in this case, the network side still periodically allocates Gap-related information to the terminal.

[0157] Step 907: No Gap needs to be allocated for cell measurement.

[0158] When the network side determines that a Gap is not required based on the capability report of the terminal device, the network side configures measurement control messages such as frequency in the RRC connection reconfiguration message and does not allocate Gap related information.

[0159] Step 908: The terminal device performs measurement according to the measurement control sent by the network and reports the measurement result.

[0160] Step 909: The network side configures the secondary cell according to the measurement results reported by the terminal device.

[0161] In the NSA scenario, the LTE standard currently does not have the corresponding NR measurement no Gap capability. The network defaults to allocating a Gap, and the Gap length is 6ms as specified in the LTE standard. Background: With the formulation of 5G standards, non-standalone (NSA) and standalone (SA) scenarios are being deployed. NSA refers to the LTE system as the Master Cell group (MCG) and the NR system as the Secondary Cell group (SCG). Fig. 9 The diagram shows a typical dual connection.

[0162] like Fig.10As shown, under dual connection, taking downlink data transmission as an example, the data stream is separated and merged at the PDCP (Packet Data Convergence Protocol) layer, and then the data stream is transmitted to the user simultaneously through multiple base stations. In this case, one PDCP entity can be associated with two RLC (Radio Link Control) entities, which can be understood as the PDCP layer transmitting the data stream to the RLC layer through the RLC1 and RLC2 links. Specifically, the RLC1 link can be understood as the LTE link, and the RLC2 link can be understood as the NR link. Each RLC entity corresponds to the LTE air interface and the NR air interface respectively. In this scenario, the PDCP data stream will send the PDCP message on the LTE and NR air interfaces respectively according to the obtained authorization. This method can be called the MCG Split bearer mode.

[0163] Before dual connectivity EN-DC, the terminal device needs to measure the 5G NR signal. Generally speaking, the synchronization signal period of NR is 20ms, while the Gap allocated by the LTE system is 6ms. If the LTE allocated by the network is not synchronized with the NR, LTE cannot measure NR using the Gap. At this time, the no Gap method must be used to measure NR. If LTE occupies the RF channel, the terminal device cannot measure the NR signal, resulting in the inability to stay in NR.

[0164] like Fig.11 A method for measuring network parameters of different systems is provided, as follows:

[0165] Step 1101: The terminal device resides in a first cell and a second cell, wherein the first cell and the second cell may be cells in an LTE system; generally speaking, the terminal device has reported the Gap measurement capability supported by the terminal device to the network side (base station or core network, etc.), such as InterFreqNeedForGaps mentioned in the present application, and also includes the multiple-input multiple-output capability supported by the terminal device;

[0166] In some embodiments, the terminal device may also reside in a third cell that needs to occupy four receiving channels.

[0167] Step 1102: The network system meets the triggering condition;

[0168] Usually, the trigger condition may be that the network side needs to measure the network parameters of the neighboring cells, or that the signal quality of the current serving cell is poor and lower than a preset threshold, etc., triggering the network side to measure the network parameters of the neighboring cells.

[0169] Step 1103: The network side allocates NR measurement and Gap related information;

[0170] The network side will configure the NR frequency through configuration messages, and has reported the B1 event threshold and corresponding Gap configuration accordingly. According to the definition of TS36.331 of the protocol, the B1 event means that the signal of the neighboring cell of the heterogeneous system is stronger than the absolute threshold. The terminal device uses the Gap to measure the NR frequency cell.

[0171] Step 1104: If the terminal device receives the Gap information allocated by the network side, execute step 1110; if the terminal device does not receive the Gap information allocated by the network side, the next step is to determine whether the receiving channel of the terminal device is full.

[0172] Generally speaking, the reason why the terminal device does not receive the Gap-related information sent by the network side may be due to the inconsistency of the signal cycle between the LTE system and the NR system. Fig.12 In the system, a dual link EN-DC method is shown, for example, before the step "RRC connection reconfiguration message", LTE is required to be synchronized with NR, such as Fig.13 As shown in the figure, the synchronization signal of NR is within the Gap allocated by the network. The synchronization signal period of NR is 20ms, while the Gap length allocated by the LTE system is 6ms. It cannot be guaranteed that the synchronization signal of NR is contained within 6ms. That is, if the LTE allocated by the network is not synchronized with the NR, the Gap allocated by LTE does not contain NR information, and the terminal device cannot detect NR within the Gap.

[0173] Step 1105: If the terminal device has redundant receiving channels, the idle channels are directly used to measure the network parameters of the NR cell.

[0174] In this case, the terminal device uses the remaining receiving channels to measure the network parameters of the NR cell. The network side allocates the control information of the NR measurement and does not need to allocate Gap related information.

[0175] Step 1106: If the receiving connection of the terminal device is fully occupied, the terminal device can perform neighboring area measurement in two ways, step 1107 or step 1108.

[0176] Step 1107: If the receiving channel of the current terminal device is already full, the terminal device evaluates to lower the corresponding receiving specification to perform neighboring cell measurement.

[0177] For example, if the current terminal is in the CA_1A+3A scenario and currently needs to send and receive data through 4Rx, the network needs to allocate a Gap to measure the inter-frequency cell. The terminal device further evaluates that it can achieve the purpose of not needing to allocate a Gap by lowering the current receiving specification, such as reconfiguring the layer data through the above-mentioned AssistanceInformation message.

[0178] In the implementation of this embodiment, the terminal device reduces the multi-input and multi-output capability of the terminal device, and can reconfigure the layer data by configuring the AssistanceInformation message to the network side; in a possible design, the terminal device can reduce the multi-input and multi-output capability by closing the number of its own receiving channels. It can be understood that in this case, the network side still periodically allocates Gap-related information to the terminal.

[0179] Step 1108: When the number of receiving channels of the terminal device decreases, the updated CQI and RANK parameters are reported.

[0180] Step 1109: If the receiving channel of the current terminal device is already fully occupied, the terminal device may evaluate that it can measure the leading cell by deactivating the secondary cell.

[0181] For example, if the current terminal is in the CA_1A+3A scenario and currently needs to send and receive data through 4Rx, the network needs to allocate a Gap to measure the heterofrequency cell. The terminal device can further evaluate whether it does not need to allocate a Gap by deconfiguring or deconfiguring the secondary cell CC, such as by reporting the A2 event above.

[0182] In the implementation of this embodiment, the terminal device reduces the transmission and reception of data in the secondary cell by suspending the transmission and reception of data in the secondary cell, and the secondary cell may be deactivated or deconfigured through the RRC reconfiguration message of the terminal device; in a possible design, the terminal device may suspend the transmission and reception of data in the secondary cell. It can be understood that in this case, the network side still periodically allocates Gap-related information to the terminal.

[0183] Step 1110: The terminal device suspends sending and receiving data of the secondary cell.

[0184] The terminal device performs cell measurement on the receiving channel occupied by the secondary cell and suspends data reception and transmission of the secondary cell. This can be done by deconfiguring or deactivating the secondary cell in the above-mentioned manner, and this application does not impose any restrictions.

[0185] Step 1111: The terminal device reports a measurement report.

[0186] The terminal device measures the network parameters of the NR cell according to Figure 2 Upload the measurement report to the network device in the manner shown.

[0187] Step 1112: If the NR measurement meets the network configuration B1 threshold, report the NR measurement and start the SCG adding process.

The embodiments of the present application can also be expanded to assume that RFIC has 8 receiving channels, etc., and the embodiments of the present application are not limited.
