The present disclosure relates to the field of communication technology, in particular to an information reporting method and receiving method, apparatus and device.
In order to reduce an operation and maintenance cost of network, it is desired to adopt a method for configuring user equipment (UE) reporting by a network, to reduce effort spent on manual drive tests. On the other hand, it also desired to obtain radio measurement information of a region to which a common drive test has no access.
Based on the above reasons, minimization of drive tests (MDT) was introduced in Long Term Evolution (LTE). In the same way, New Radio (NR or 5G) networks require an automatic network optimization scheme, including logging downlink (DL) coverage by UE to assist a network side in performing DL coverage optimization.
MDT in the related art continues to use the trace function. Depending on whether an element management (EM) participates in the selection of the particular UE involving in the MDT, and depending on a manner of reporting an MDT result, MDT is further divided into two categories.
1) For Logged MDT, UE obtains logged MDT configuration through dedicated signaling in a radio resource control (RRC) connected state. Having entered an idle state, the UE collects MDT measurement results, and the UE reports the collected results to the network side in a subsequent connected state. Once a configured trigger condition (conventionally, only periodic collection of results is supported) is met, the UE obtains and stores (or logs) a measurement result, and reports the same to an eNB (evolved Node B or base station)/radio network controller (RNC) at a subsequent appropriate occasion.
In LTE, to support DL coverage optimization, the network side notifies UE of relevant Logged MDT configuration through a dedicated RRC message. The configuration information includes: collection interval: the periodicity of logging the logged MDT results; collection duration: it defines a time duration in which the MDT configuration remains valid after the MDT configuration is sent to UE.
Optionally, the configuration information further includes: a logging area configured by the network, such as a cell list or tracking area (TA) list, where the UE only performs the logging measurement when in the logging area; trace collection entity (TCE) identifier corresponding to the collected result reporting, which is used for subsequent data processing of TCE.
After entering the idle state, the UE then logs DL coverage information periodically based on the collection interval. The DL coverage information includes: identifiers of a serving cell and neighboring cells, corresponding signal strengths and signal qualities; time stamp information: it indicates the time when the logging occurs; location information: it indicates the location where the logging occurs.
2) For Immediate MDT, MDT measurement and reporting performed by UE in the connected state. MDT measurement quantity collected by UE and the MDT measurement quantity obtained by a base station statistically are included.
An NR base station supports signal transmission in a manner of multi-beam sweeping. When measuring a certain cell, UE obtains multiple beam-level measurement results of the cell, and the UE should be able to calculate a cell-level measurement result based on one or more beam-level measurement results.
In order to assist a network side in a handover, and assist a target cell in configuring appropriate RACH resources, in addition to the reporting of the cell-level measurement result, a connected-state UE needs to carry a beam-level measurement result in a measurement report according to the requirement configured by the network side. An L3 filtering of both the cell-level measurement result and the beam-level measurement result according to a network side configuration is required to obtain a final L3 measurement result.
In NR, when performing a cell reselection, an idle-state/inactive-state UE adopts a cell-level measurement result obtaining rule same as that adopted by the connected-state UE; a cell-level measurement result obtaining rule for the idle-state/inactive-state UE in performing a cell selection is not specified. In addition, in conventional protocols, an L3 filtering of the cell-level measurement result performed by a non-connected-state UE is not specified, and an L3 filtering of the beam-level measurement result provided by L1 is not required.
An NR network differs from an LTE network in some respects. A solution as to how to collect downlink (DL) coverage information in NR to assist a network in optimizing DL coverage is not discussed in the related art.

In a specific implementation, the step 121 may include: step 1210, transmitting the beam-level relevant information to the network device when a report request transmitted by the network device is received.
In a specific implementation, the step 121 may also include:
In some embodiments of the present disclosure, the step 12 may specifically include: transmitting the beam-level relevant information to the network device through a dedicated message.
Specific implementations of the foregoing embodiment are described hereinafter with respect to specific scenarios.
Step 1: a network device configures UE in a non-connected state (including UE in an idle or inactive state) to log beam-level relevant information periodically, and configuration information includes: a time interval T, that is, how often a result is logged periodically; a valid duration of logging, which, similar to the logged MDT mechanism in LTE, defines a time span in which the configuration is valid.
Optionally, the configuration information configures a layer-3 filtering parameter corresponding to the beam-level measurement result, e.g., a filtering factor.
Optionally, the configuration information configures a threshold value for logging the beam-level relevant information.
Optionally, the configuration information configures a maximum value k of quantity of logged beam-level relevant information.
Optionally, the configuration information configures the UE to only log beam-level relevant information corresponding to a serving cell.
Optionally, the configuration information configures the UE to log beam-level relevant information corresponding to the serving cell and surrounding neighboring cells, at this time, the configuration information may further configure in advance a maximum quantity of neighboring cells to be logged.
Step 2: optionally, according to the configuration in step 1, the UE in the non-connected state performs an L3 filtering on beam-level measurement results delivered from L1, e.g., reference signal received power (RSRP) and reference signal received quality (RSRQ) corresponding to a certain beam, to obtain L3-filtered beam-level measurement results.
According to the configuration in step 1, the UE in the non-connected state periodically, at an interval of T, logs beam-level relevant information, time-related information (so that a network side may be aware of the time when the logging occurs), and location related information (so that a network side may be aware of the location where the logging occurs).
According to the configuration at the network side, or as pre-defined in a protocol, the beam-level relevant information may include only the beam-level relevant information corresponding to a current serving cell, or include the beam-level relevant information corresponding to the serving cell and surrounding neighboring cells (the maximum quantity of neighboring cells to be logged may be pre-defined, or configured in advance in step 1).
In addition to identifiers of the serving cell and/or neighboring cells, the beam-level relevant information corresponding to the serving cell and/or neighboring cells that is logged by the UE in the non-connected state includes one or more of:
Here, when logging the beam-level relevant information corresponding to a certain cell, the UE may log all beam-level relevant information detected in the cell; alternatively, the logged information may be restricted, for example, the UE only logs beam-level relevant information corresponding to the beam-level measurement result exceeding a predefined threshold in the cell (the threshold may be configured in the step 1, or may be predefined), or the UE logs beam-level relevant information corresponding to top k beam-level measurement results in the cell ranked according to the measurement result (k may be configured in the step 1, or may be predefined).
Step 3: after entering the connected state, the UE reports to the network side the measurement results collected in step 1. The network side may perform DL coverage optimization according to the beam-level relevant information reported by the UE.
Possible UE reporting manners include that, 1) the UE may report to the network side the indication indicating that the beam-level relevant information is available (which may be carried in an RRC (connection) establishment complete message, an RRC (connection) recovery complete message, an RRC (connection) reestablishment complete message or a new RRC message); the network side derives from the indication that the UE has collected beam-level relevant information; the network side determines, according to its own algorithm, whether the UE should report the collected beam-level relevant information, if so, the network side requests the UE to report the collected beam-level relevant information; at the request of the network side, the UE reports the logged beam-level relevant information; 2) the network side determines, according to its own algorithm, whether the UE should report the collected results, if so, the network side requests the UE to report the collected beam-level relevant information; at the request of the network side, the UE reports the logged beam-level relevant information; 3) the UE voluntarily reports the collected beam-level relevant information to the network side through an uplink message.
Further, in the embodiment, according to the configuration in step 1, the UE in the non-connected state may periodically, at an interval of T, log a cell-level measurement result, and meanwhile log time-related information, location related information and the like.
Step 1: when the UE in the non-connected state exits a coverage area (i.e., out of coverage), the UE processes the beam-level relevant information, and logs time-related information and location related information. The processing the beam-level relevant information includes at least one of: logging, by the UE, beam-level relevant information at this time when the UE exits the coverage area; logging, by the UE, that the UE exits the coverage area at this time when the UE exits the coverage area.
For example, when the UE in the non-connected state exits the coverage area, the UE may log a currently detectable cell and beam-level relevant information of the currently detectable cell (if there is no detectable cell, NULL may be used to identify the detectable cell and beam-level relevant information of the cell), time-related information and location related information; or, the UE may log a currently detectable cell and beam-level relevant information of the currently detectable cell (if there is no detectable cell, NULL may be used to identify the detectable cell and its beam-level relevant information of the currently detectable cell), time-related information, location related information and a 1-bit flag indicating that the UE exits the coverage area; or, the UE may not log any cell and corresponding beam-level relevant information, and only log the 1-bit flag indicating that the UE exits the coverage area.
Step 2: optionally, when the UE re-enters the coverage area, the UE processes the beam-level relevant information, and logs time-related information and location related information. The processing the beam-level relevant information includes at least one of: when the UE re-enters the coverage area after exiting the coverage area, logging, by the UE, beam-level relevant information at this time; when the UE re-enters the coverage area after exiting the coverage area, logging, by the UE, that the UE re-enters the coverage area at this time.
For example, when the UE in the non-connected state re-enters the coverage area, the UE may log a serving cell or detectable cell (including the serving cell and neighboring cell), beam-level relevant information of the cell, time-related information and location related information; or, the UE may log the serving cell or detectable cell and its beam-level relevant information of the cell, time-related information, location related information and a 1-bit flag indicating that the UE re-enters the coverage area; or, the UE may not log any cell and corresponding beam-level relevant information, and only log the 1-bit flag indicating that the UE re-enters the coverage area.
In the embodiment, the content of the beam-level relevant information in the above step 1 and step 2 is the same as that in the step 2 of embodiment 1.
In the step 1, the UE may log, in an incremental manner, a total number of times the UE exits the coverage area. For example, if the UE exits the coverage area at time instants T1, T2 (T2>T1) and T3 (T3>T2), the UE logs its exiting the coverage area at each of the time instants T1, T2 and T3.
For example, at the time instant T1, the UE logs the beam-level relevant information, and/or exiting the coverage area once, and/or location information, and/or time information; at the time instant T2, the UE logs the beam-level relevant information, and/or exiting the coverage area twice, and/or location information, and/or time information; at the time instant T3, the UE logs the beam-level relevant information, and/or exiting the coverage area three times.
In subsequent reporting to the network side, the UE may only report the result of the time instant T3, or the UE may report the results of the time instants T1, T2 and T3.
In the same way, in the step 2, the UE may log, in an incremental manner, a number of times the UE re-enters the coverage area after exiting the coverage area.
Step 3: the UE reports the collected measurement results to the network side after entering the connected state. The network side may discover a coverage loophole according to information reported by the UE, to perform DL coverage optimization.
Possible UE reporting manners include that, 1) the UE may first report to the network side the indication indicating that a coverage problem is available (which may be carried in an RRC (connection) establishment complete message, an RRC (connection) recovery complete message, an RRC (connection) reestablishment complete message or a new RRC message); the network side derives from the indication that the UE has collected results about exiting the coverage area and/or re-entering the coverage area; the network side determines, according to its own algorithm, whether the UE should report the collected measurement results, if so, the network side requests the UE to report the collected results; at the request of the network side, the UE reports the logged results; 2) the network side voluntarily requests the UE to report collected results about exiting the coverage area and/or re-entering the coverage area; at the request of the network side, the UE reports the logged results; 3) the UE voluntarily reports the collected results to the network side through an uplink message.
Here, the example in step 3 is a case in which the UE separately reports the results about exiting the coverage area and/or re-entering the coverage area to the network side. Sometimes, an embodiment 3 may be a special example of the process of the embodiment 1, in this case, the step 3 in the embodiment 3 is the same as the step 3 of the embodiment 1, i.e., the UE reports the results about exiting the coverage area and/or re-entering the coverage area along with other collected results about normal coverage to the network side.
In the above embodiments of the present disclosure, UE in the non-connected state processes beam-level relevant information, to assist the network side in performing DL coverage optimization, especially the beam-level DL coverage optimization.
Some embodiments of the present disclosure further provide an information receiving method. The method is applied to a network device and includes: receiving the beam-level relevant information reported by the UE in a non-connected state.
Prior to the receiving the beam-level relevant information reported by the UE in the non-connected state, the information receiving method further includes at least one of: transmitting configuration information to UE; transmitting a report request for beam-level relevant information to UE; receiving an indication transmitted by the UE indicating that the beam-level relevant information is available or an indication reported by the UE indicating that a coverage problem is available.
The configuration information includes at least one of: a time interval T of logging the beam-level relevant information; a valid duration of logging the beam-level relevant information; a layer-3 filtering parameter corresponding to the beam-level measurement result; a threshold value for logging the beam-level relevant information; a maximum value k of quantity of logged beam-level relevant information; beam-level relevant information to be logged corresponding to a serving cell; beam-level relevant information to be logged corresponding to the serving cell and a neighboring cell; a maximum quantity of neighboring cells to be logged.
It is noted, all implementations of the UE side method are applicable to embodiments at the network device side, and may achieve the same technical effects.
