Definitions
- the present invention relates to the field of communications, and in particular to a method, system, and user equipment for measuring results in a multi-carrier system (User Equipment In order to provide higher data rates to mobile users, the Long Term Evolution Advance (LTE-A) technology proposes Carrier Aggregation (CA) technology.
- LTE Long Term Evolution Advance
- CA Carrier Aggregation
- the purpose is to provide a larger bandwidth for user equipment with corresponding capabilities to improve the peak rate of the UE.
- the maximum downlink transmission bandwidth supported by the system is 20 MHz
- carrier aggregation is to use two or more component carriers (Component Carriers).
- CC component carriers
- each component carrier performing carrier aggregation may be continuous in the frequency domain. It can also be discontinuous.
- the LTE-A system using carrier aggregation technology is more than one.
- Carrier system In a mobile communication system, a UE can move between cells. To ensure service continuity and ensure service quality, after a user establishes a service, the UE needs to perform measurement according to the configuration of the serving base station, and report the satisfaction to the serving base station. The serving base station configures the required measurement report, so that the serving base station can make a reasonable handover decision according to the measurement information of the UE and other Radio Resource Management (RRM) algorithms, that is, selecting a reasonable one.
- RRM Radio Resource Management
- the target cell performs the handover to meet the mobility requirement.
- the measurement behavior of the UE is controlled by the base station, and the specific process of the measurement is:
- Step 1 The network side (for example, the serving base station) sends a measurement control message to the UE, where
- the measurement control message includes a measurement object (Measurement Object, referred to as MO) list, the MO includes the LTE frequency to be measured, and each frequency is uniquely identified by a MOID (measObjectld); a report configuration (Report Configuration, referred to as RC) list, Includes attributes for each measurement report configuration, Whether the measurement report is an event report or a periodic report, and corresponding configuration parameters, such as the event type reported by the event and related parameters of the event type, and the duration of the trigger condition reported by the event (Time To Trigger, referred to as TTT), etc.
- MO Measurement Object
- RC Report Configuration
- Measurement report The configuration is uniquely labeled with an RCID (reportConfigld); a list of measurement IDs (MIDs), which is the identifier of each specific measurement task. In the MID list, each MID is associated with a MOID and an RCID, thereby uniquely characterizing one.
- the measurement task that is, uniquely characterizes the measurement configuration information at a certain frequency.
- There is also a measurement threshold (s-Measure) that represents the signal quality threshold of the resident cell; a Quantity Configuration to indicate the specific measurement; a Measurement Gap Configuration for the inter-frequency, Configuration of different system measurements, etc.
- Step 2 The UE receives the measurement control message, and the number of the measurement tasks is obtained by the number of the MIDs.
- the attributes of the measurement tasks that is, the MO information and the RC information of each measurement task are obtained by using the MOID and the RCID corresponding to the MID.
- Step 3 The UE performs measurement according to the configuration of the measurement control message, and reports the measurement 4 report that satisfies the RC configuration of each measurement task.
- the UE measures the configured frequency (MO), and performs event evaluation on the measurement result of each cell measured on the frequency, and determines that the measurement result of the cell is in the RC configuration.
- the UE When the configured TTT time meets the entry conditions of the events configured in the RC configuration, and the cells have not been saved, the UE locally saves the cells satisfying the entry condition and their measurement results to a MID using the measurement task.
- the identified cell list ( cellsTriggeredList )
- the N best cells specified in the RC configuration are obtained from the cell list in order of strong to weak signal quality, a measurement report is generated, and the measurement report is sent to the network side.
- the UE performs an event evaluation, and determines that the cell in the cell list that the measurement result satisfies the leaving condition of the event configured by the RC configuration in the TTT time configured by the RC configuration, the UE compares the cells that satisfy the leaving condition.
- the measurement result is deleted from the cell list.
- the UE After the deletion operation, if no cell information is stored in the cell list, the UE deletes the cell list identified by the MID locally.
- the UE in order to ensure the communication quality of the UE, the UE needs to always measure the serving cell in the connected state, and for the neighboring cell, the UE needs to consume additional power when measuring, especially for the inter-frequency and the different system neighboring cells. Measurement, if the UE has only one radio frequency receiving device, the UE only allows the radio frequency receiving device to adjust from the serving cell to the neighboring cell to perform measurement within the measurement gap configured by the base station, without affecting the UE's communication in the serving cell; Reporting measurement reports can also take up too much wireless resources.
- the serving base station determines whether the signal quality of the UE is in the serving cell.
- Configure the inter-frequency/different for the UE The system measurement, in particular, may be configured according to the following policies: a measurement event for the serving cell configured by the base station for the UE, an event A1 (the signal quality of the serving cell is greater than a threshold) and event A2 (the signal quality of the serving cell is less than
- the measurement result of the threshold is determined whether the UE performs or stops the inter-frequency/differential system measurement task.
- the base station may configure the inter-frequency/differential system measurement task for the UE, and receive the A1 event reported by the UE. , You can delete the inter-frequency/different system measurement task previously configured for the UE.
- the base station needs to configure the measurement event for the neighboring cell for the UE.
- the base station may determine whether to switch the UE to the adjacent cell by measuring the decision of the advertisement and other RRM algorithms to perform handover.
- the base station may configure information of multiple carriers (called a configuration carrier or a working carrier) for the UE, and activate some or all of the carriers, so that the UE performs data transmission on the activated carriers at the same time.
- a configuration carrier or a working carrier For activate a carrier, other carriers that have been configured but not yet activated may be referred to as inactive carriers.
- the power consumption of the UE is one of the key issues to be considered in designing the carrier aggregation related technology. Therefore, in order to ensure the communication quality of the UE, it does not consume too much.
- the base station in carrier aggregation also needs to consider the signal quality of each activated carrier to determine whether to configure inter-frequency/differential system measurement for the UE. Switching the UE to the adjacent cell will interrupt the data transmission of the UE in the serving cell in a short time during the handover process, and even cause a certain data loss. At the same time, the handover process itself will bring a large system overhead, so in addition to some operations
- the special strategy of the quotient (such as load balancing), unless the UE cannot guarantee the quality of data transmission in the serving cell, or the base station determines that there is a better neighboring cell than the current serving cell, the base station generally does not easily switch the UE to Adjacent cell.
- the base station In carrier aggregation, in order to minimize unnecessary handover, the base station also needs to comprehensively consider the signal quality of each activated carrier to determine whether to handover the UE to the adjacent cell.
- a trigger condition for example, the serving cell satisfies an entry trigger condition or a leave trigger condition of a related event (A1 event and A2 event), or the neighboring cell satisfies the comparison. Entry of type events (A3 events and A5 events)
- the trigger condition is generated, the measurement report is generated and reported to the base station, that is, the triggering and reporting policy is adopted for all the measurement tasks, and the reporting method is applied to carrier aggregation lacking flexibility.
- a primary object of the present invention is to provide a method, system and user equipment for measuring results in a multi-carrier system to at least solve the above problems.
