Description
Technical Field
The present invention relates to carrier measurement technologies, and in particular, to a method and a system for measuring a carrier in a multi-carrier system.
Background
In a Long Term Evolution (LTE) system, the maximum transmission bandwidth supported by the system is 20 MHz. In order to provide a higher data rate for a mobile User, a Carrier Aggregation technology (CA) is proposed in a Long Term Evolution advanced (LTE-a) system, which aims to provide a larger bandwidth for a User Equipment (UE) with a corresponding capability and increase a peak rate of the UE. The CA aggregates two or more Component Carriers (CCs) to support a transmission bandwidth greater than 20MHz, up to 100 MHz. An LTE-a system employing carrier aggregation technology is a multi-carrier system.
Fig. 1 is a schematic diagram of carrier aggregation according to the related art, and as shown in fig. 1, each component carrier performing carrier aggregation may be continuous or discontinuous in a frequency domain. To support carrier aggregation so that a UE can simultaneously operate on multiple carriers, the radio frequency structure of the UE needs to meet corresponding requirements. Taking the example that the UE supports downlink carrier aggregation in a Frequency Division Duplex (FDD) mode, if receiving more than two discontinuous component carriers, the UE needs more than two radio receiving devices (receivers) to receive data on the multiple discontinuous component carriers at the same time; if more than two contiguous component carriers in the frequency domain are received, the UE needs to have one radio receiving apparatus with a maximum bandwidth exceeding 20MHz to receive data on multiple contiguous component carriers simultaneously, relative to a radio receiving apparatus with a maximum bandwidth of 20MHz in a single carrier system, or if the UE has multiple radio receiving apparatuses, the UE can receive data on the multiple contiguous component carriers simultaneously using the multiple radio receiving apparatuses.
Similarly, for the UE supporting uplink carrier aggregation under FDD, if the UE simultaneously transmits data on more than two discontinuous component carriers, the UE needs to have more than two radio transmitters (transmitters); if the UE transmits data on more than two consecutive component carriers simultaneously, the UE needs to have a radio transmission device with a maximum bandwidth exceeding 20MHz or more than two radio transmission devices. The same is true for the Time Division Duplex (TDD) mode in which the UE supports carrier aggregation. The above Receiver and Transmitter may be implemented in the UE as the same device, i.e. a unified radio transceiver device, or radio frequency unit.
After introducing the carrier aggregation technology, a base station (eNB, evolved NodeB) may configure up to 5 cells for a UE. After the UE establishes a service in a cell, because the UE traffic increases or based on Radio Resource Management (RRM) requirements of the base station, the base station may add a new cell configuration to the UE through a Radio Resource Control (RRC) signaling, specifically including configuration information related to uplink and downlink carriers of the newly added cell. On the contrary, because the UE traffic flow is reduced, or the signal quality of the cell currently configured to the UE is degraded, or RRM management based on the base station, the base station may delete the cell already configured to the UE through RRC signaling, specifically, the cell includes configuration information of uplink and downlink carriers of the deleted cell. The above processes of adding and deleting cell configurations may occur simultaneously.
In the process of adding or deleting the cell configuration, the base station configures a Primary serving cell (Pcell) for the UE through explicit configuration or according to protocol agreement, a Downlink Carrier in which the Pcell operates is called a Downlink Primary Carrier (DL PCC, Downlink Primary Component Carrier), an Uplink Carrier in which the Pcell operates is called an Uplink Primary Carrier (UL PCC), other cells except the Pcell configured for the UE by the base station are called Secondary serving cells (scells, serving cells), a Downlink Carrier in which the Scell operates is called a Downlink Secondary Carrier (DL SCC, Downlink Secondary Component Carrier), and an Uplink Carrier in which the Scell operates is called an Uplink Secondary Carrier (UL SCC, Uplink Secondary Component Carrier).
In the above, multiple cells are configured for the UE through RRC signaling, that is, the UE operates on multiple carriers, and the UE needs to use a radio transceiver with a bandwidth exceeding 20MHz or use multiple radio transceivers, which greatly increases battery power consumption of the UE. Therefore, considering the burst characteristics of the traffic, although the UE may use up to 5 carriers of bandwidth, the actual traffic flow of the UE is very little or close to zero in the burst gap, which may result in high power overhead if the UE continues to receive/transmit data on multiple carriers. Therefore, in order to extend the operating time of the UE, turn off unnecessary radio transceiver devices, and reduce unnecessary battery consumption, a carrier activation/deactivation mechanism may be introduced on the basis of the above-mentioned increase/decrease of cell configuration (carrier configuration). The downlink carrier and the uplink carrier in one cell can be activated/deactivated independently. The base station activates/deactivates the secondary carrier by explicit Media Access Control (MAC) command notification or by agreed implicit rule. To ensure continuity of communication, the primary carrier is activated once configured, i.e., the activation/deactivation mechanism is performed only for the secondary carrier.
The UE performs data reception only on the activated Downlink carrier, for example, only monitoring a Physical Downlink Control Channel (PDCCH); on the deactivated downlink carrier, the UE does not monitor the PDCCH and does not receive data on a Physical Downlink Shared Channel (PDSCH), thereby achieving the purpose of saving power.
The UE only transmits data on the activated uplink carrier; on the deactivated Uplink carrier, the UE stops sending Uplink data, including stopping sending Uplink Reference signals (SRS), stopping sending data on a Physical Uplink Control Channel (PUCCH), stopping sending data on a Physical Uplink Shared Channel (PUSCH), and the like.
In an LTE system, in order to meet both power saving and measurement requirements, frequencies in the system are divided into two measurement requirements, namely a common-frequency measurement requirement and a different-frequency measurement requirement. The measurement requirements include: identification (identity) time of a cell, measurement accuracy, and the like. The measurement in the LTE system is mainly used for supporting switching judgment, and the measurement requirement of the same frequency is higher than that of the different frequency because the frequency of the same frequency switching is more frequent than that of the different frequency switching, and the different frequency measurement requires the UE to adjust a radio frequency unit, and the measurement is more troublesome only at a service frequency point compared with the same frequency measurement. For example, during the co-frequency measurement, the cell identification time is 800ms, and the measurement period is 200ms, whereas during the inter-frequency measurement, if 1 inter-frequency is configured and the configured measurement time slot (measurement gap) is in the case of mode 0 (period 40), the basic cell identification time is 3840ms, and the measurement period is 480 ms. In addition, under the condition of configuring the DRX, the requirements of same-frequency and different-frequency measurement are further relaxed along with the DRX period in consideration of the requirement of power saving.
According to the existing conclusion, three carrier configuration modes may exist in the UE of the LTE-a system in the connected state, which are respectively configuring and activating a carrier, configuring and deactivating a carrier, and not configuring a carrier. The same-frequency measurement requirement of the LTE system is adopted for the activated carrier, and the different-frequency measurement requirement is adopted for the unconfigured carrier. While the requirements for employing that measurement have not been determined for configuring and deactivating carriers. Since the measurement of the deactivated carrier serves more in the carrier management part, the deactivated carrier can be activated quickly according to the change of the service. Therefore, if the measurement requirement is relaxed, for example, measurement is performed according to the requirement of inter-frequency measurement, which results in slow reflection of the radio quality change of the deactivated carrier, and the deactivated carrier and the activated carrier use the same measurement requirement, which results in that the UE needs to measure the deactivated carrier like the activated carrier, and power consumption is inevitably high.

Detailed Description
The basic idea of the invention is that there are multiple measurement requirements for the deactivated carrier, and different measurement requirements are applied according to different states of the deactivated carrier. The corresponding relation between the measurement state judgment and the measurement requirement can be that a predefined corresponding relation is configured in the UE, or the predefined corresponding relation is broadcasted to the UE by a network side or sent to the UE through a special signaling, and each UE measures the deactivated carrier wave according to the set measurement requirement, so that the UE can dynamically adjust the measurement requirement on the deactivated carrier wave according to the state change of the deactivated carrier wave.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
The state of deactivating the carrier may deactivate a radio state of the carrier, deactivate a transmission state of the carrier, deactivate a priority state of the carrier.
The radio state of the deactivated carrier is determined by the signal quality of the deactivated carrier. The transmission state of the deactivated carrier or the priority state of the deactivated carrier is similar to the radio state but is different from the judgment condition, for example, the transmission state may be obtained according to previous historical transmission statistics of the carrier or the priority state set according to information indicated by the eNB.
Firstly, setting a corresponding relation between a measurement requirement of a deactivated carrier and a condition that the signal quality needs to meet, and when the signal quality of the deactivated carrier meets the condition, the UE measures the deactivated carrier according to the measurement requirement.
Specifically, the correspondence between the radio status and the measurement requirement is that when the signal quality of the deactivated carrier meets the condition of better signal quality or worse, the UE measures the deactivated carrier with a lower measurement requirement (measurement requirement 1). The signal quality is better or worse is judged by the condition that the corresponding signal quality meets the condition, the lower measurement requirement is relative to the higher measurement requirement, the specific measurement needs to be described in detail later, and if the different-frequency measurement requirement in the LTE system is lower than the same-frequency measurement requirement, the lower measurement requirement can be the different-frequency measurement requirement in the LTE system, namely the measurement requirement for deactivating the carrier is consistent with the measurement requirement for the different-frequency cell; or consistent with measurement requirements for DRX for active carrier configurations.
When the signal quality of the deactivated carrier cannot meet the condition of good signal quality or poor signal quality, the UE measures the deactivated carrier with a higher measurement requirement (measurement requirement 2). The higher measurement requirement may be a relatively lower inter-frequency measurement requirement, such as a frequency measurement requirement, that is, a measurement requirement for deactivating carriers is consistent with a measurement requirement for an intra-frequency cell or other activated serving cells thereof; or the measurement requirement of the DRX with the activated carrier configuration is consistent, wherein the measurement requirement of the DRX configuration is higher than the DRX configuration with the lower measurement requirement.
Specifically, the correspondence may also be that when the signal quality of the deactivated carrier satisfies that the signal quality is good, the UE measures the deactivated carrier with a lower measurement requirement (measurement requirement 1). When the deactivated carrier meets the condition of poor signal quality, the UE measures the deactivated carrier with higher measurement requirement (measurement requirement 2).
The Signal quality condition may be specifically a threshold condition of a measurement quantity, and the measurement condition may be Power of a Received Reference Signal (RSRP) or quality of a Reference Signal Received by the UE (RSRQ) in dB in LTE. The threshold condition may be that the measured quantity is above or below a certain threshold value, or above and below a certain threshold value. The threshold value may be an absolute threshold, such as a deactivation carrier RSRP higher than N dBm, a deactivation carrier RSRQ lower than M dB, or a deactivation carrier RSRP higher than a dBm and lower than B dBm; wherein A, B, M and N are both real numbers. The above threshold may also be a relative threshold, which may be a measurement quantity relative to a specified Cell, for example, relative to a serving Cell, and in an LTE-a system, the serving Cell may be a Primary Cell (Primary Cell) in carrier aggregation, for example, an RSRP of a deactivated carrier is higher than an rsrqk (real number) dB of the Primary Cell. The threshold condition may be that the eNB notifies the UE through dedicated or common signaling, or may be specified by the UE itself, such as a threshold that can be flexibly adjusted according to its own capability or power saving requirement, or may be a threshold predefined by a protocol. To prevent false triggering of the signal quality condition due to signal fluctuation, the signal quality trigger may be a filtered result, such as the measured value is filtered by L3 of LTE before being subjected to condition judgment.
The measurement requirements comprise the measurement capability requirement of the UE, the frequency measurement number and time requirement, the cell detection number and time requirement, and the cell measurement number and time requirement. Wherein, the more the number of the measurement, the shorter the measurement time means the higher the measurement requirement. Taking the measurement time as an example, the measurement period of the co-frequency cell in the LTE system is 200 ms; the measurement period of the inter-frequency cell is related to the configuration of the measurement GAP (GAP) and the number of frequencies to be measured (including all inter-frequency frequencies and inter-system frequencies measured by using the GAP), when the GAP pattern 0(GAP pattern0) is used, the measurement period is 480 × Nfreq, and when the GAP pattern 1(GAP pattern1) is used, the measurement period is 240 × Nfreq, wherein Nfreq is the number of frequencies; the configured measurement requirement is also related to a DRX period, when the DRX period is less than 40ms, the same-frequency measurement period is 200ms as the same-frequency measurement period of the unconfigured DRX, and when the DRX period is more than 40ms, the same-frequency measurement period is 5 s; the inter-frequency measurement period is related to the GAP pattern, when the DRX period is less than 160ms, the measurement period is the same as the same-frequency measurement period of the non-configured DRX, when the DRX period is 256ms, the measurement period is 5.12 XNfreq, and when the DRX period is 320ms, the measurement period is 6.4 XNfreq. The present invention is not limited to specific measurement requirement parameters, and in the following description, the existing defined measurement requirements are taken as an example, but the present invention is not limited to be only applicable to the defined measurement requirements, and is also applicable to measurement requirements that may be newly added in the future.
The following specific examples illustrate specific uses of the above-described process.
In the embodiment, a wireless state is adopted, and the relative conditions are used for judgment, so that the condition 1 is that RSRP Scell is larger than RSRP cell-2dBm, the condition 2 is that RSRP Scell is smaller than RSRP cell-5dBm, and the condition 3 is that the condition 1 or the condition 2 cannot be met. The corresponding measurement requirements include 2 common-frequency measurement requirements and different-frequency measurement requirements. The condition 1 or the condition 2 is satisfied to correspond to the different-frequency measurement requirement, and the condition 3 is satisfied to correspond to the same-frequency measurement requirement.
The base station configures 2 carriers for the UE to perform carrier aggregation, and the carriers are a primary cell (primary cell) Pcell and a secondary cell (secondary cell) Scell. The Pcell and the Scell have uplink and downlink carriers at the same time, the downlink carrier of the Pcell belongs to a 2G Hz frequency band, and the Scell belongs to an 800M Hz frequency band. Generally, the UE performs carrier aggregation on such carriers with relatively far frequency band, that is, the carriers in one frequency band are received by using a group of independent rf receiving circuits. The Pcell is in an active state by default, and the Scell is in an inactive state by default. When the traffic flow of the UE increases, the Scell is activated for data transmission, when the traffic flow decreases, the eNB may notify the UE to deactivate the Scell, or the UE may enter a deactivated state by itself according to a deactivation timer when there is no data transmission for a period of time. Meanwhile, the eNB also configures corresponding measurement for the UE, the eNB configures the UE to measure a frequency F1 where the Pcell is located, a frequency F2 where the Scell is located, and another frequency F3, and configures MeasurementGAP as pattern 0. According to the measurement requirement of an LTE system, the UE measures the cell on the frequency of the Pcell according to the same frequency measurement requirement configured by non-DRX, namely the cell on the frequency of the Pcell is measured by taking 200ms as a period, and the cell on the frequency of F3 is measured by 480 XNfreq according to the regulation. According to a set rule, when the deactivated carrier wave meets the signal quality meeting the condition 1 (in the embodiment, a relative threshold is adopted, such as RSRP Scell > RSRPCell-2 dBm), the deactivated Scell is measured by using the different-frequency measurement requirement, otherwise, the cell on the frequency where the deactivated Scell is located is measured by using the same-frequency measurement requirement. If the Scell meets the condition that RSRP Scell is larger than RSRPPCell-2dBm, the Scell signal is better, and the Scell signal does not need to be frequently measured, UE measures the Scell and other adjacent cells on F2/F3, the Scell signal is measured in each GAP, the measurement requirement is 480 XNfreq according to the requirement of inter-frequency measurement, and the Nfreq is 2 at the moment, namely the Scell signal is measured in the GAP once every 960 ms. Similarly, further, when the signal quality meets the condition 2 (relative threshold RSRP Scell < rsrpcell-5 dBm), it indicates that the Scell signal is poor, is not suitable for being activated, and does not need to be measured frequently. When the Scell signal is between strong and weak, whether the Scell signal is suitable for activation or not is required to be determined as early as possible; in addition, the UE needs to shorten the measurement period for deactivating the Scell, and for example, in this embodiment, when the Scell signal quality satisfies the condition that the condition 1 or the condition 2 cannot be satisfied, that is, RSRP Scell < rsrpcell-2 dBm and RSRP Scell > rsrpcell-5 dBm, the UE measures the Scell by using the same-frequency measurement requirement, that is, the Scell deactivated is measured once every 200 ms. In order to meet the measurement requirement, for this embodiment, when the UE has redundant unused rf receiving circuits, the UE may activate the independent rf receiving circuit to measure the cell on the frequency where the Scell is located. If the Pcell and the Scell belong to the same frequency band, as belonging to a 2G frequency band, the Scell needs to tune a receiver thereof when the RSRP Scell < RSRPCell-2 dBm and the RSRP Scell > RSRPCell-5 dBm are met, and simultaneously receive and measure the Pcell and the Scell, wherein the Pcell and the Scell use the same measurement requirement. After the condition 1 or the condition 2 is met, for the UE with the redundant receiver, the UE can close the special receiver of the Scell and measure the Scell in the GAP, for the UE without the redundant receiver, the receiver can be tuned when the condition is met, only the Pcell is received, the different frequency measurement requirement is adopted for the Scell, and the measurement is carried out in the GAP.
The condition that the signal quality should satisfy may be preset, or configured by the eNB through common signaling or dedicated signaling. For example, the dedicated signaling may be configured through a measurement task of the LTE system, such as configuring an a1 event or an a2 event of the Scell, where a1 indicates that the serving cell is better than the specified threshold 1, for example, 80dBm is taken in this embodiment, and a2 indicates that the serving cell is worse than the specified threshold 2, for example, 100dBm is taken in this embodiment. When the Scell satisfies the a1 event or the a2 event, that is, enters a triggered cell list (CellTriggerList) of the a1 event or the a2 event, at this time, when a signal for deactivating the Scell is good enough or bad enough, it may be determined that the deactivated Scell may be activated or may not be deactivated, the Scell adopts a looser measurement requirement to achieve the purpose of power saving, in addition to the above-described inter-frequency measurement requirement, it may also be configured to perform measurement requirement relaxation in a manner similar to a DRX cycle, for example, a measurement cycle with a DRX greater than 40ms is used, and measurement is performed every 5s, and the latter is suitable for the Pcell to configure a DRX scenario, for example, the DRX cycle is configured to 0.256s, and at this time, the inter-frequency cell measurement cycle is extended to 5.12 × nfreq s. When the deactivated carrier does not satisfy the a1 event and the a2 event, i.e. is not in the trigger cell list of the a1 event or the a2 event, according to the above rule, the deactivated Scell adopts the measurement requirement of the activated carrier, which is the same as the measurement requirement of the PCell.
Fig. 2 is a schematic diagram illustrating dynamic adjustment of measurement requirements according to signal quality change, as shown in fig. 2, two horizontal dashed lines in the diagram are condition 1 and condition 2, where the set measurement requirements are relatively low and the measurement activities are relatively small when the deactivated carrier condition is better or worse, and the measurement activities are relatively frequent when the deactivated carrier condition is located between the two horizontal dashed lines in the diagram. Fig. 2a is another schematic diagram of dynamically adjusting the measurement requirement according to the signal quality change, as shown in fig. 2a, the dashed line in the diagram corresponds to the aforementioned set condition 3, when the condition 3 (lower part of the dashed line) cannot be satisfied, the measurement requirement is relatively high, the measurement activity is relatively frequent, and when the condition 3 (upper part of the dashed line) is satisfied, the set measurement requirement is relatively low, and the measurement activity is relatively small.
The above is the scenario that the two radio states correspond to two measurement requirements, and another typical manner may also be the scenario that the two radio states correspond to two measurement requirements, according to a certain threshold, this threshold may be predefined or specified by the eNB to the UE, such as the above-mentioned a1 event or a2 event, or otherwise specified s-threshold. When the UE judges that the deactivated cell meets the A1 event or is greater than s-threshold, the signal for deactivating the Scell is good enough, the deactivated Scell is determined to be activated, and the Scell adopts the loose measurement requirement to achieve the purpose of saving power. Otherwise, when the eNB does not satisfy the event a1, or satisfies the event a2 or is less than s-threshold, the signal for deactivating the Scell is not good enough, it cannot be determined that the activated Scell can be activated, and the Scell adopts the measurement requirement with higher requirement.
In a word, the UE dynamically adjusts the measurement requirement on the deactivated carrier according to the signal quality change of the deactivated carrier, so that the effects of quickly activating the deactivated carrier and saving electricity are achieved
