Description

RRM measurement method and device, storage medium, UE and base station
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for RRM measurement, a storage medium, a UE, and a base station.
Background
Radio resource management (Radio resource management, RRM) measurement is a basic activity to achieve mobility management and is also an important component of UE power consumption. In the existing protocol of the narrowband internet of things (Narrow Band Internet of Things, abbreviated as NB-IoT), the UE does not support RRM measurement in a connection STATE (rrc_connection STATE), that is, after the radio link connection of the UE fails, the UE needs to enter an idle STATE, perform target cell search, perform measurement activity on the target cell, then select a cell with better cell quality as a target cell according to the measurement result, initiate an RRC reestablishment procedure based on the selected target cell, and further complete a cell reselection procedure. In the existing mobility management mechanism based on link failure, the UE needs to spend a lot of time to perform cell search and measurement activities after the link failure, and thus, serious cell reselection delay is caused.
To reduce the delay required for the radio resource control (Radio Resource Control, RRC) re-establishment procedure, the UE may perform some RRM measurement activity, i.e. neighbor measurement activity, before the radio link fails. In this case, the UE already knows the target cell before the radio link fails, and the UE does not need to perform the search of the target cell during the RRC reestablishment process, thereby greatly reducing the time delay of cell reselection. The time interval during which a terminal pauses communication with a serving cell to measure an inter-frequency neighbor or other radio neighbor is called a Measurement Gap (Measurement Gap).
The Gap required for RRM measurement in the prior art may use the existing data Transmission Gap (Transmission Gap). However, the current data transmission gap is configured by RRC signaling and only occurs during transmission, for example, the data transmission gap may occur during transmission of a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) or during transmission of a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH for short). If RRM measurement is performed using the data transmission gap, there may be some cases where the UE does not have enough transmission gap to perform measurement activity (e.g., where data traffic is sparse or the configured transmission gap period is sparse or the length of the transmission gap is too small).

Detailed Description
As described in the background, the data transmission gap in the prior art is configured by RRC signaling and the data transmission gap only occurs during transmission, which may cause the UE to have insufficient transmission gap to perform measurement activity in some cases.
Data transfer gap for NB-IOT: for downlink Transmission (Downlink Transmission, DL Transmission for short), in order to ensure effective utilization of resources, a mechanism of data Transmission gap (Transmission Gap) is introduced by NB-IOT to avoid that a certain UE occupies a channel for a long time. The network configures a threshold of data transmission gap, and when the maximum number of repeated transmissions of the PDCCH configured by the RRC message is greater than the threshold of the transmission gap, a periodic data transmission gap is inserted during the PDCCH or PDSCH transmission, wherein the period of the data transmission gap and the length of the gap are configured by the network.
Referring to fig. 1, fig. 1 is a schematic diagram of a time domain distribution of a data transmission gap (gap) in the prior art; the diagonal line area is the time domain distribution of the received downlink data, and the blank area is the data transmission gap. The data transmission gap is configured periodically, and the length of the data transmission gap per cycle is fixed. Assuming that the threshold value of the data transmission gap is 32 and the maximum repetition number of PDCCH configured by RRC signaling is 64, the UE satisfies the condition of the data transmission gap, the repetition number of PDSCH is 128, the period of the data transmission gap is 32ms, and the length of the data transmission gap is 8ms.
In order to solve the above problems, the present invention provides a RRM measurement method and apparatus, a storage medium, a UE, and a base station, where the method includes: if the RRM measurement is judged to be required to be executed, starting the RRM measurement by using the initial data transmission gap configuration, and starting a first timer; when the timing time length of the first timer reaches a first preset time length and the number of the current data transmission gaps in the first preset time length is smaller than a preset value, adjusting the used data transmission gap configuration; performing RRM measurements using the adjusted data transmission gap configuration; wherein the current data transmission gap is determined by the data transmission gap configuration used.
Therefore, the UE can have enough transmission gap to complete measurement activities when the RRM measurement needs to be executed.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 2, fig. 2 is a flow chart of an RRM measurement method according to an embodiment of the invention, which includes:
step S201, if it is determined that RRM measurement needs to be executed, starting RRM measurement by using initial data transmission gap configuration, and starting a first timer;
the data transmission gap configuration (also simply referred to as configuration) is a network configuration, and is a set of parameters such as a period of data transmission gap, a gap length, a threshold value, and the like. Each configuration corresponds to a set of data transfer gaps.
The initial data transmission gap configuration is configured as the data transmission gap configuration configured for the UE in the downlink transmission by the network, and if multiple sets of data transmission gap configurations exist on the UE side, the configuration used by the current UE is called the initial data transmission gap configuration.
When the UE needs to perform RRM measurement, before the UE performs cell handover, the UE may perform RRM measurement by using the gap corresponding to the configuration being used in the current cell (i.e., the current data transmission gap), and when RRM measurement is started, the UE starts a first timer to count time, so as to determine the time for the UE to perform RRM measurement.
Step S202, when the timing duration of the first timer reaches a first preset duration and the number of current data transmission gaps in the first preset duration is smaller than a preset value, adjusting the used data transmission gap configuration;
the first preset duration is a preset time threshold used for judging whether the gap of the current RRM measurement executed by the UE side meets the measurement requirement.
The preset value is a threshold value of the number of gaps for judging whether the gaps for the current RRM measurement of the UE side meet the measurement requirement.
Optionally, the first preset duration and the preset value may be configured to the UE by the network side. The network may send it to the UE through higher layer signaling such as RRC signaling or a broadcast message. Further, the first preset duration and the preset value may be sent to the UE by the network side when the network side instructs the UE to perform RRM measurement.
Step S203, RRM measurement is executed by using the adjusted data transmission gap configuration; wherein the current data transmission gap (gap) is determined by the data transmission gap configuration used.
At the same time as the RRM measurement is initiated, the UE counts the data transmission gap experienced (i.e., the current data transmission gap). If the timing duration of the timer reaches the first preset duration and the number of the current data transmission gaps in the first preset duration is smaller than the preset value, the fact that the currently used data transmission gap of the UE cannot meet the RRM measurement requirement is indicated, the currently used data transmission gap needs to be changed, and the changing mode is to adjust the configuration of the currently used data transmission gap.
The adjustment mode may be preset, so that the UE adjusts the currently used gap configuration according to the preset adjustment mode, so that the UE performs RRM measurement using the data transmission gap capable of meeting the RRM measurement requirement.
Optionally, when the timing duration of the timer reaches a first preset duration and the number of the current data transmission gaps in the first preset duration is greater than or equal to a preset value, performing RRM measurement by using the initial data transmission gap configuration continuously.
That is, if the UE can meet the RRM measurement requirement using the initial configuration, the RRM measurement can be continuously performed using the initial configuration without adjusting the initial configuration.
Further, after the configuration adjustment is completed, RRM measurement may be re-performed, or RRM measurement that has been performed before may be continued.
Further, after completing the RRM measurement, the UE performs cell handover again.
In this embodiment, the RRM measurement method described in fig. 2 is performed by the UE side. Before the UE performs cell switching, RRM measurement can be performed according to the data transmission gap corresponding to the current configuration, and whether the current data transmission gap meets the measurement requirement is tested when the RRM measurement is performed, if not, the current configuration is adjusted to change the used data transmission gap so as to meet the measurement requirement of the RRM, so that the RRM measurement is successfully completed before the cell switching.
In one embodiment, if the number of PDSCH repetitions indicated by the network exceeds a preset number threshold, it is determined that RRM measurements need to be performed.
For a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in uplink transmission, transmission of PUSCH is suspended for 40ms every 256 milliseconds (ms) and then continued. The prior art relates to repeated transmissions of NB-IOT: to guarantee coverage, the NB-IOT employs a technique of repeated transmissions. The maximum number of repetitions is 2048 for downlink transmission and 128 for uplink transmission. The repetition number of PDSCH/PUSCH is dynamically indicated by DCI, namely, UE determines the repetition number of PDSCH according to the indication of DCI, and the maximum repetition number of PDCCH is configured by RRC semi-static state.
Specifically, the number of repeated transmissions of PDSCH is generally indicated by downlink control information (Downlink Control Information, abbreviated DCI) in PDCCH. The UE may acquire the number of repeated transmissions of PDSCH from the DCI and then determine whether RRM measurements need to be performed.
Optionally, the preset frequency threshold may be sent to the UE by the network side when the network side instructs the UE to perform RRM measurement.
In this embodiment, the network may indicate the number of repeated transmissions of PDSCH exceeding a preset number of thresholds to instruct the UE to perform RRM measurements.
In one embodiment, at least 2 sets of data transmission gap configurations are preset, and referring to fig. 2, the adjusting the data transmission gap configuration in step S202 includes: and selecting a data transmission gap configuration with a data transmission gap period smaller than that of the initial data transmission gap configuration or with a data transmission gap length larger than that of the initial data transmission gap configuration from the preset data transmission gap configuration as an adjusted data transmission gap configuration.
When the UE side is configured with a plurality of sets of data transmission gap configurations, the configuration meeting the RRM measurement requirements can be selected for use. Optionally, the network configures multiple sets of preset data transmission gap configurations for the UE through RRC messages.
In general, the UE-side data transmission gap configuration cannot meet the RRM measurement requirement, and because the data transmission gap period is sparse or the gap length is too small, the data transmission gap configuration with a denser gap period or a larger gap length can be selected as the adjusted data transmission gap configuration.
In another embodiment, the adjusting the data transmission gap configuration in step S202 may further include: and adjusting the gap period and/or the gap length in the initial data transmission gap configuration according to a preset coefficient (scaling factors) to obtain an adjusted data transmission gap configuration.
The preset coefficient is a preset coefficient used for adjusting the gap period and/or the gap length in the initial configuration, and the preset coefficient is one or more coefficients. The preset coefficient may be configured to the UE by the network side. When the configured preset coefficients comprise a plurality of coefficients, the network can also instruct the UE to select at least one coefficient from the DCI or the MAC CE to adjust the gap period and/or the gap length of the initial data transmission gap configuration.
For example, for adjustment of the gap period, the preset coefficient is {1,1/2,1/4,1/8}. When the preset coefficient is 1, the gap period is kept unchanged; when the preset coefficient is 1/2,1/4 or 1/8, it means that the UE reduces the gap period in the initial configuration by 2 times, 4 times or 8 times.
For adjusting the gap length, the preset coefficients are {1,2,4,8}. When the preset coefficient is 1, the gap length is kept unchanged; when the preset coefficient is 2,4 or 8, it indicates that the UE expands the size of the gap length in the initial configuration by 2 times, 4 times or 8 times.
In addition, the gap period and the gap length can be modified simultaneously according to a certain coefficient, for example, assume that the predetermined coefficient is {1,1/2,1/4,1/8}. When the preset coefficient is 1, the gap period and the gap length are kept unchanged; when the preset coefficient is 1/2,1/4 or 1/8, the period of transmitting the gap is reduced by 2 times, 4 times or 8 times, and the gap length is enlarged by 2 times, 4 times or 8 times.
In this embodiment, the UE may only set a set of data transmission gap configuration (i.e. initial configuration), and if it needs to be adjusted to meet the RRM measurement requirement, the adjustment objective may be achieved by a method of configuring a preset coefficient.
In one embodiment, the RRM measurement method shown in fig. 2 may further include: starting timing when starting RRM measurement; and when the timing duration reaches a second preset duration, ending the RRM measurement.
After the UE starts the RRM measurement, another timer may be started to start counting, and if the counted time length reaches the second preset time length, the RRM measurement is ended. So as to avoid that RRM measurement is executed too long, and normal data transmission at the UE side is affected.
The second preset duration can be set according to the data transmission condition of the UE side, the signal strength of the cell to which the UE is currently connected, and the like.
And starting timing when the UE starts RRM measurement, and ending the RRM measurement if the timing time length reaches a second preset time length.
In one embodiment, the method further comprises: counting the number of current data transmission gaps experienced when starting RRM measurement; when the counted value reaches the gap threshold, the RRM measurement is ended.
The UE may count the number of current data transmission gaps experienced and set a gap (gap) threshold to control the UE to end RRM measurements. If the gap threshold is set to be M, the measurement is automatically ended when the UE experiences M gaps after the measurement is started.
Optionally, the second preset duration and the gap threshold may be configured to the UE by the network side, and the network may send the second preset duration and the gap threshold to the UE through higher layer signaling (such as RRC signaling or a broadcast message). Further, the second preset duration and the gap threshold may be configured to the UE by the network side when the UE is instructed to perform RRM measurements.
In this embodiment, after the UE starts RRM measurement, a time threshold (i.e. a second preset duration) or a gap threshold may be set for the UE to control the UE to automatically end measurement, so as to avoid that RRM measurement is performed too long, which affects normal data transmission on the UE side.
In one embodiment, after initiating the RRM measurement, further comprising: and receiving a measurement ending instruction, and ending RRM measurement according to the measurement ending instruction.
Optionally, the measurement end instruction is carried by DCI or MAC CE.
Because DCI and MAC CE are dynamic signaling, less resources are occupied by transmission, and the configuration of transmission gap can be adjusted in real time.
When the network side hopes that the UE does not conduct RRM measurement any more, a measurement ending instruction can be sent to the UE so that the UE ends the RRM measurement process.
Optionally, for the above embodiment, if the UE adjusts the initial configuration during RRM measurement, after the UE finishes RRM measurement, the adjustment made before needs to be recovered, that is, the initial data transmission gap configuration is returned.
Optionally, the one or more predetermined sets of data transmission gap configurations configured by the UE may include a default data transmission gap configuration, which may be switched to after the UE finishes RRM measurements.
Referring to fig. 3, another RRM measurement method is provided in the embodiment of the present invention, including:
step S301, instructing the UE to start RRM measurement so that the UE performs RRM measurement by using the initial data transmission gap configuration;
step S302, when the UE starts RRM measurement, a second timer is started;
step S303, when the timing duration of the second timer reaches a first preset duration and the number of the current data transmission gaps of the UE in the first preset duration is smaller than a preset value, determining the adjusted data transmission gap configuration of the UE;
and the UE performs RRM measurement by using the adjusted data transmission gap configuration, and the current data transmission gap is determined by the data transmission gap configuration used by the UE.
When the UE performs RRM measurement, the network side also tracks the measurement status of the UE at any time to determine the situation where the UE performs RRM measurement and when to end RRM measurement. Therefore, after the UE starts the RRM measurement, the network side may determine, through the same detection mechanism as the UE, that is, the mechanism for timing by the second timer, whether the UE needs to adjust the initial data transmission gap configuration and the data transmission gap configuration used when the UE actually performs the RRM measurement.
Optionally, the UE is instructed to initiate RRM measurements by indicating the number of PDSCH repetitions exceeding a preset number of thresholds.
Optionally, at least 2 sets of data transmission gap configurations are preset for the UE, and the adjusted data transmission gap configuration is a data transmission gap configuration obtained by selecting, from the preset data transmission gap configurations, that the data transmission gap period is smaller than the initial data transmission gap configuration or that the data transmission gap length is greater than the initial data transmission gap configuration by the UE.
Optionally, the adjusted data transmission gap configuration is a data transmission gap configuration obtained by adjusting a gap period and/or a gap length in the initial data transmission gap configuration according to a preset coefficient by the UE.
In one embodiment, the method further comprises: starting timing when the UE starts RRM measurement; and when the timing duration reaches a second preset duration, determining that the UE finishes RRM measurement.
In one embodiment, the method further comprises: counting the number of current data transmission gaps experienced when the UE starts RRM measurement; when the timed value reaches a gap threshold, determining that the UE ends RRM measurement.
In one embodiment, the method further comprises: after the UE starts RRM measurement, a measurement ending instruction is sent to the UE, so that the UE ends RRM measurement.
Optionally, the measurement end instruction is carried by DCI or MAC CE.
Optionally, after the UE ends RRM measurements, the UE returns to the initial data transmission gap configuration.
The RRM measurement method described in fig. 3 is performed by the network side or the base station side, and for more details about the working principle and the working manner, reference may be made to the description related to the network side in the RRM measurement method in fig. 2, which is not repeated here.
