Description

RRM (radio resource management) measuring method and device, storage medium, UE (user Equipment) and base station
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a RRM measurement method and apparatus, a storage medium, a UE, and a base station.
Background
Radio Resource Management (RRM) measurement is a basic activity for implementing mobility management and is also an important component of UE energy consumption. Currently, in an existing protocol of a narrowband Internet of Things (NB-IoT for short), a UE does not support RRM measurement in a connected STATE (RRC _ connected STATE), that is, after a radio link of the UE fails to connect, the UE needs to enter an idle STATE and perform search of a target cell, perform search and measurement activities on the target cell, select a cell with better cell quality as the target cell according to a measurement result, and initiate an RRC reestablishment process based on the selected target cell to complete a cell reselection process. In the existing mobility management mechanism based on link failure, after the link failure, the UE needs to spend a lot of time to perform cell search and measurement activities, and therefore, a serious cell reselection delay is caused.
In order to reduce the time delay required for the Radio Resource Control (RRC) reestablishment process, the UE may perform some RRM measurement activities, that is, neighbor measurement activities, 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 in the RRC reestablishment process, thereby greatly reducing the cell reselection delay. The time interval during which the terminal suspends communication with the serving cell to measure the inter-frequency neighbor cell or other wireless neighbor cells is called a Measurement Gap (measgap).
The Gap required for RRM measurement in the related art may use an existing data Transmission Gap (Transmission Gap). However, the current data transmission gap is configured by RRC signaling and only occurs during the transmission process, for example, the data transmission gap may occur during the transmission process of a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH). Performing RRM measurements using the data transmission gap may result in the UE not having sufficient transmission gaps to perform measurement activities in some cases (e.g., when data traffic is sparse or configured transmission gap periods are sparse or the length of the transmission gap is too small).

Detailed Description
As described in the background, in the prior art, the data transmission gap is configured by RRC signaling and the data transmission gap only occurs during the transmission process, which may result in that the UE has insufficient transmission gap to perform the measurement activity in some cases.
Data transfer gap for NB-IOT: for Downlink Transmission (DL Transmission for short), in order to ensure effective utilization of resources and avoid a certain UE from occupying a channel for a long time, the NB-IOT introduces a mechanism of data Transmission gap (Transmission gap). The network configures a threshold of a 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 needs to be inserted during the transmission of the PDCCH or the PDSCH, wherein the period of the data transmission gap and the length of the gap are both configured by the network.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a time domain distribution of a data transmission gap (gap) in the prior art; the slash region is the time domain distribution for receiving downlink data, and the blank region is a data transmission gap. The data transmission gap is configured periodically, and the length of the data transmission gap per period is fixed. Assuming that the threshold of the data transmission gap is 32, and the maximum number of repetitions of the PDCCH configured by the RRC signaling is 64, the UE satisfies the condition of the data transmission gap, the number of repetitions of the PDSCH is 128, the period of the data transmission gap is 32ms, and the length of the data transmission gap is 8 ms.
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 needs to be executed, starting the RRM measurement by using initial data transmission gap configuration, and starting a first timer; when the timing duration of the first timer reaches a first preset duration and the number of the current data transmission gaps in the first preset duration is smaller than a preset value, adjusting the configuration of the used data transmission gaps; 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 the measurement activity when the RRM measurement needs to be performed.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 2, fig. 2 is a flowchart illustrating a RRM measurement method according to an embodiment of the present invention, where the method includes:
step S201, if it is determined that RRM measurement needs to be performed, starting RRM measurement using initial data transmission gap configuration, and starting a first timer;
the data transmission gap configuration (also referred to as configuration for short) is network configuration, and includes parameters such as a period of data transmission gap, a gap length, and a threshold. Each configuration corresponds to a set of data transfer gaps.
The initial data transmission gap configuration is data transmission gap configuration configured for the UE by the network in downlink transmission, and if multiple sets of data transmission gap configurations exist on the UE side, the configuration currently used by the UE is called initial data transmission gap configuration.
When the UE needs to perform RRM measurement, before the UE performs cell handover, the UE may first perform RRM measurement by using a gap corresponding to a configuration currently used in a current cell (i.e., a current data transmission gap), and when the RRM measurement is started, the UE side starts a first timer to time, so as to determine a time for the UE to perform the RRM measurement.
Step S202, when the timing duration of the first timer reaches a first preset duration and the number of the current data transmission gaps in the first preset duration is less than a preset value, adjusting the configuration of the used data transmission gaps;
the first preset duration is a preset time threshold used for judging whether gap of the currently executed RRM measurement at the UE side meets the measurement requirement.
The preset value is a gap number threshold used for judging whether gap of the current RRM measurement executed by the UE side meets 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 broadcast messages. 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, performing RRM measurement using the adjusted data transmission gap configuration; wherein the current data transmission gap (gap) is determined by the data transmission gap configuration used.
While the RRM measurement is initiated, the UE counts the experienced data transmission gap (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, it indicates that the data transmission gap currently used by the UE cannot meet the RRM measurement requirement, and the data transmission gap currently used needs to be changed in a manner of adjusting the configuration of the data transmission gap currently used.
The adjustment mode can 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 satisfying the RRM measurement requirement.
Optionally, when 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 greater than or equal to the preset value, the initial data transmission gap configuration is continuously used to perform the RRM measurement.
That is, if the UE can satisfy the RRM measurement requirement using the initial configuration, the RRM measurement may be continuously performed using the initial configuration without adjusting the initial configuration.
Further, after the configuration adjustment is completed, the RRM measurement may be re-performed, or the RRM measurement that has been performed before may be continued.
Further, after completing the RRM measurement, the UE performs the cell handover again.
In this embodiment, the RRM measurement method illustrated in fig. 2 is executed by the UE side. Before the UE performs the cell handover, the RRM measurement may be performed according to the data transmission gap corresponding to the currently used configuration, and whether the current data transmission gap meets the measurement requirement is tested while performing the RRM measurement, and if not, the current configuration is adjusted to change the used data transmission gap and meet the measurement requirement of the RRM, so that the RRM measurement is successfully completed before the cell handover.
In one embodiment, if the number of repetitions of the PDSCH indicated by the network exceeds a preset number threshold, it is determined that RRM measurement needs to be performed.
For a Physical Uplink Shared Channel (PUSCH) in Uplink transmission, transmission of a PUSCH needs to be suspended for 40ms every 256 milliseconds (ms), and then transmission is continued. In the prior art, for repeated transmission of NB-IOT: in order to ensure the coverage, the NB-IOT adopts the technology of repeated transmission. The maximum number of repetitions is 2048 for downlink transmission and 128 for uplink transmission. The number of the repeated PDSCH/PUSCH is dynamically indicated by the DCI, namely the UE determines the number of the repeated PDSCH according to the indication of the DCI, and the maximum number of the repeated PDSCH is configured by RRC in a semi-static mode.
Specifically, the number of repeated transmissions of the PDSCH is usually indicated by Downlink Control Information (DCI) in the PDCCH. The UE may acquire the number of repeated transmissions of the PDSCH from the DCI, and then determine whether RRM measurement needs to be performed.
Optionally, the preset number 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 the PDSCH exceeding a preset number threshold to instruct the UE to perform RRM measurements.
In an embodiment, at least 2 sets of data transmission gap configurations are preset, please refer to fig. 2, and the adjusting the used data transmission gap configuration in step S202 includes: and selecting the data transmission gap configuration with the data transmission gap period smaller than the initial data transmission gap configuration or the data transmission gap length larger than the initial data transmission gap configuration from the preset data transmission gap configuration as the adjusted data transmission gap configuration.
When a plurality of sets of data transmission gap configurations are configured on the UE side, the configuration meeting the RRM measurement requirement can be selected from the sets of data transmission gap configurations for use. Optionally, the network configures multiple sets of preset data transmission gap configurations for the UE through an RRC message.
In general, the reason why the data transmission gap configuration on the UE side cannot meet the RRM measurement requirement is that the data transmission gap period is sparse or the gap length is too small, so the data transmission gap configuration with a denser gap period or a larger gap length may be selected as the adjusted data transmission gap configuration.
In another embodiment, adjusting the data transmission gap configuration used in step S202 may further include: and adjusting the gap (gap) period and/or the gap (gap) length in the initial data transmission gap configuration according to a preset coefficient (scaling factors) to obtain the adjusted data transmission gap configuration.
The preset coefficients are pre-configured coefficients for adjusting the gap period and/or the gap length in the initial configuration, and the preset coefficients are one or more coefficients. The preset coefficient can be configured to the UE by the network side. When the preset configured coefficient comprises a plurality of coefficients, the network may further instruct the UE to select at least one coefficient from the preset configured coefficient through 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 the adjustment of the gap period, the preset coefficient is {1, 1/2, 1/4, 1/8 }. Wherein, 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 indicates 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 predetermined coefficient is {1, 2, 4, 8 }. Wherein, when the preset coefficient is 1, the gap length is kept unchanged; when the preset coefficient is 2, 4 or 8, it means 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, assuming that the preset 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 predetermined coefficient is 1/2, 1/4, or 1/8, it means that the period of transmitting the gap is reduced by 2 times, 4 times, or 8 times, and the gap length is increased by 2 times, 4 times, or 8 times.
In this embodiment, the UE may only set a set of data transmission gap configurations (i.e., initial configurations), and if the UE needs to adjust the configuration to meet the RRM measurement requirement, the adjustment may be achieved by configuring a preset coefficient.
In one embodiment, the RRM measurement method illustrated 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 timing, and if the timing duration reaches a second preset duration, the RRM measurement is ended. So as to avoid the RRM measurement from being performed too long to affect the normal data transmission on the UE side.
The second preset time length 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 duration reaches a second preset duration.
In one embodiment, the method further comprises: counting the number of experienced current data transmission gaps when starting RRM measurements; 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 the RRM measurement. If the gap threshold is set to be M, when the UE experiences M gaps after starting measurement, the measurement is automatically ended.
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 a higher layer signaling (e.g., RRC signaling or broadcast message). Further, the second preset duration and the gap threshold may be configured to the UE by the network side when instructing the UE to perform the RRM measurement.
In this embodiment, after the UE starts the RRM measurement, a time threshold (i.e. a second preset duration) or a gap threshold may be set for the RRM measurement, so as to control the UE to automatically end the measurement, thereby preventing the RRM measurement from being performed too long to affect the normal data transmission at the UE side.
In one embodiment, after initiating the RRM measurement, further comprising: and receiving a measurement ending instruction, and ending the RRM measurement according to the measurement ending instruction.
Optionally, the measurement ending instruction is carried by DCI or MAC CE.
Because DCI and MAC CE are dynamic signaling, the resources occupied by transmission are less, and the gap configuration of transmission can be adjusted in real time.
When the network side desires that the UE does not perform RRM measurement any more, a measurement ending instruction may 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 the RRM measurement, after the UE finishes the RRM measurement, the UE needs to recover the adjustment made before, that is, return to the initial data transmission gap configuration.
Optionally, the one or more preset sets of data transmission gap configurations configured by the UE may include a default data transmission gap configuration, and the UE may switch to the default configuration after ending the RRM measurement.
Referring to fig. 3, another RRM measurement method is further provided in the embodiment of the present invention, which includes:
step S301, instructing UE to start RRM measurement so as to enable the UE to execute RRM measurement by using 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 less than a preset value, determining the configuration of the data transmission gaps after the UE is adjusted;
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 keeps track of the measurement status of the UE at any time to determine the situation when the UE performs RRM measurement and when to end RRM measurement. Therefore, after the UE side starts the RRM measurement, the network side may determine 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 through the same detection mechanism as the UE side, that is, the mechanism of the second timer for timing.
Optionally, the UE is instructed to initiate RRM measurement by indicating a number of PDSCH repetitions that exceeds a preset number threshold.
Optionally, the UE presets at least 2 sets of data transmission gap configurations, and the adjusted data transmission gap configuration is a data transmission gap configuration obtained by selecting, by the UE, a data transmission gap configuration from the preset data transmission gap configurations, where a data transmission gap period is smaller than an initial data transmission gap configuration, or a data transmission gap length is larger than the initial data transmission gap configuration.
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 by the UE according to a preset coefficient.
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 ends RRM measurement.
In one embodiment, the method further comprises: counting the number of experienced current data transmission gaps when the UE starts RRM measurement; determining that the UE ends RRM measurement when the timed value reaches a gap threshold.
In one embodiment, the method further comprises: after the UE starts RRM measurement, sending a measurement ending instruction to the UE so that the UE ends RRM measurement.
Optionally, the measurement ending instruction is carried by DCI or MAC CE.
Optionally, after the UE finishes RRM measurement, the UE returns to the initial data transmission gap configuration.
The RRM measurement method illustrated in fig. 3 is executed by the network side or the base station side, and for more content of the working principle and the working mode, reference may be made to the description related to the network side in the RRM measurement method in fig. 2, and details are not repeated here.

wherein the current data transmission gap is determined by the data transmission gap configuration used.
