Description

Information processing method, device, equipment and readable storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information processing method, an apparatus, a device, and a readable storage medium.

Background

BWP (Bandwidth Part) is introduced in NR (New Radio) technology. Regarding the configuration of BWP, there are two types of UE (User Equipment) capabilities in the prior art: a BWP of a terminal configuration that may be referred to as a basic capability, supporting the basic capability must include SSBs (Synchronization Signal and PBCH block, synchronization signal/physical broadcast channel signal blocks); a terminal that may be referred to as an optional capability, supports the optional capability may not include SSB in the configured BWP.

For conventional eMBB (Enhanced Mobile Broadband ) terminals, a single carrier bandwidth of 100MHz can be supported below 6GHz, so inclusion of SSB in BWP can be guaranteed by flexible bandwidth configuration even for terminals that do not support optional capabilities. But for low capability Redcap (Reduced Capabilities, low capability) terminals, which can only support bandwidths of 20MHz or less, if optional capabilities are not supported, BWP needs to be configured at the location of SSB, which may cause congestion of capacity; but if not so configured, the UE will not be able to make SSB related RRM (Radio resource management ), RLM (Radio Link Monitoring, radio link monitoring), BFD (Bidirectional Forwarding Detection, bi-directional forwarding monitoring), etc. measurements.

For the above problems, several solutions are provided in the prior art. However, the prior art approaches all incur significant overhead.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relationship of the association objects, which means that three relationships may exist, for example, a and/or B may be represented: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

For the problems mentioned in the background art, one solution in the prior art is to configure a terminal on a BWP without SSB and then switch to the BWP with SSB through the BWP to perform measurement. However, a problem with this solution is that RRM, RLM, BFD belongs to L1 measurement, and at present, the L1 measurement is specified to be continuously performed in the protocol, that is, measurement gap is not needed, if the L1 measurement is performed through BWP handover, the BWP handover has a certain overhead, ensuring that the L1 measurement is performed through frequent BWP handover will result in a larger overhead, and an effective mechanism is needed to ensure that network congestion and system overhead are avoided as much as possible without affecting the performance of the L1 measurement. Another possible solution is to configure measurement gap, in the prior art, only support L3 measurement gap for mobility management and neighbor measurement, and not use L1 measurement, even if L1 measurement gap is introduced, there is a problem of measurement discontinuity, and meanwhile, since data transmission cannot be performed in the measurement gap, measurement overhead is increased, and throughput is reduced.

To solve the above-described problems, embodiments of the present application provide an information processing method to reduce overhead while ensuring L1 measurement performance.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step 101, a terminal receives BWP configuration information sent by a network device, where the BWP configuration information includes one or more of the following:

first information indicating information of BWP for L1 measurement;

BWP switch configuration information.

Wherein the L1 measurement comprises one or more of:

In this embodiment of the present application, if the BWP configuration information includes first information or a value indicating the first information is a first preset value (e.g. TRUE), the BWP indicated by the first information may be considered to be used for L1 measurement. If the first information is not included or a value indicating the first information is a second preset value (e.g., FALSE) or not, the BWP indicated by the first information may be considered to be unavailable for L1 measurement. This way may be referred to as a way of displaying an indication whether BWP is available for L1 measurement.

Wherein the configuration information for monitoring beam failure and/or radio link failure comprises configuration information of a reference signal. If a BWP is configured with the configuration information of the reference signal, the BWP can be considered to be used for L1 measurement; otherwise it cannot be used for L1 measurement. This way may be referred to as an implicit way of indicating whether BWP is available for L1 measurement.

Wherein the BWP switch configuration information comprises an Identification (ID) of the first target BWP and/or a switch target or cause. The first target BWP may also be referred to as a switched BWP, including BWP for L1 measurement or BWP not usable for L1 measurement, etc. The handover targets or reasons include for L1 measurement and/or radio link monitoring and/or beam failure detection, or for positioning, etc.

After receiving the BWP configuration information, the terminal determines a second target BWP according to the BWP configuration information, wherein the second target BWP is a BWP for L1 measurement. The terminal may also perform L1 measurement using the second target BWP.

For example, the terminal may regard the BWP indicated by the first information as the second target BWP; alternatively, the terminal may take BWP including configuration information configuring a reference signal as the second target BWP; alternatively, the terminal may take BWP for L1 measurement indicated by the BWP switching configuration information as the second target BWP, or the like.

As can be seen from the above description, in the embodiment of the present application, the terminal receives BWP configuration information of the network device, so that the terminal can determine BWP information for L1 measurement according to the BWP configuration information, frequent BWP handover is avoided, and overhead can be reduced while ensuring L1 measurement performance. Moreover, by using the scheme of the embodiment of the application, the measurement interval (measurement gap) is not required to be configured for L1 measurement, the problem of measurement discontinuity caused by the measurement gap is avoided, the measurement cost is saved, and the throughput is improved.

Optionally, on the basis of the foregoing embodiment, the terminal may further send auxiliary information to the network device, where the auxiliary information includes one or more of the following:

measurement completion indication information;

BWP switch request.

The time window for the terminal to execute the L1 measurement is used for the terminal to execute the L1 related measurement.

In practical application, a certain continuity is needed for terminal measurement to ensure the reliability of the measurement result. This is because if the measurement switches BWP, but the BWP is switched without waiting for the measurement of the terminal, the measurement requirement of the terminal cannot be satisfied, resulting in performance degradation. The current protocol defines a time window (e.g., several hundred ms) required for the terminal to perform RLM, BFD, etc. measurements, where the time window is the worst case measurement time window. When the actual terminal measures, because of different implementations and different channel quality, the time window possibly needed is smaller than the time specified in the protocol, so if the time window is not reported, the network equipment can only schedule the terminal according to the longest time window specified in the protocol, thereby affecting the performance and efficiency of the system. Therefore, in the embodiment of the application, the terminal sends the second indication information to the network device, so that the network device can accurately determine the time window to schedule the terminal, and the system performance and efficiency are improved.

The measurement completion indication information is used for indicating that the L1 measurement is completed. After the L1-related measurement is completed, the terminal transmits measurement completion instruction information to the network. At this time, the network device may switch the terminal to other BWP not including SSB or not used for L1 measurement for continuing data transmission.

Wherein the BWP switch request comprises an Identification (ID) of the third target BWP and/or a switch reason. The reason for the handover may be L1 measurement completion or the like. The third target BWP may be a destination BWP for which the terminal requests the handover.

By transmitting the auxiliary information to the network device, the network device can accurately perform BWP switching configuration on the terminal.

Optionally, on the basis of the foregoing embodiment, the terminal receives one or more of the following information sent by the network device:

Wherein the event comprises one or more of:

(1) The measurement result of the serving cell is worse or better than the absolute threshold;

(2) The measurement result of the serving cell is worse or better than an absolute threshold in a certain time;

(3) The measurement result of the serving cell is worse or better than the relative threshold;

(4) The measurement results of the serving cell are worse or better than the relative threshold for a certain time.

Wherein the threshold information may include: a first threshold and a second threshold. The first threshold is an absolute threshold, such as a threshold of RSRP and/or RSRQ and/or SINR, etc. And through the first threshold, the terminal determines whether the BWP needs to be switched. E.g. the measurement result is below the threshold, the terminal sends a measurement report to the network device, which configures the terminal to switch BWP. The second threshold is a relative threshold, such as a rate of change or a value of change of RSRP and/or RSRQ and/or SINR. And through the second threshold, the terminal determines whether the BWP needs to be switched. E.g. RSRP and/or RSRQ and/or SINR, above which threshold the terminal sends a measurement report to the network device, which configures the terminal to switch BWP.

The absolute threshold in the third information may be a first threshold, and the relative threshold may be a second threshold.

The information of the timers may include a time duration of the first timer and a time duration of the second timer. If the terminal determines that the measurement results obtained in the time duration of the first timer are lower than the first threshold, the terminal sends a measurement report to the network equipment, and the network equipment configures the terminal to switch BWP. If the terminal determines that the measurement results obtained in the timing duration of the second timer are all higher than the second threshold, the terminal sends a measurement report to the network equipment, and the network equipment configures the terminal to switch BWP.

The timing duration of the first timer or the timing duration of the second timer can be set according to actual needs.

And if the terminal determines that the measurement result of the serving cell meets the third information or the threshold information, the terminal sends a measurement report to the network equipment, and/or the terminal sends BWP switching information to the network equipment. Wherein, the BWP switching information is used for indicating the switching BWP, and optionally may include the identification of the destination BWP of the switching, the reason of the switching, etc.

Optionally, on the basis of the foregoing embodiment, the terminal may send BWP handover information to the network device, where the BWP handover information includes one or more of the following:

Request information for switching BWP;

reasons for switching BWP;

the fourth target BWP identification.

Wherein, the request information of the switch BWP may be a BWP switch request initiated by the terminal. For example, if the terminal finds that its current channel quality is unstable or poor, or the terminal does not measure for a period of time, the terminal initiates a request message for switching BWP to the network. The terminal may carry cause information when requesting BWP handover, and the cause information may include: l1-related measurements or to complete measurements. The fourth target BWP identity may also be referred to as the target BWP identity of the handover. The terminal may select BWP that can be used for measurement as a target BWP or select BWP that is not used for measurement as a target BWP from the configured BWP and inform the network device of the BWP ID of the selected target BWP to perform BWP handover configuration by the network device.

As can be seen from the above embodiments, by using the solution according to the embodiments of the present application, the L1 measurement performance of the terminal can be ensured under the condition of minimizing the BWP switching and measurement interval overhead.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 2, including the following steps:

step 201, the network device sends BWP configuration information to the terminal.

first information indicating information of BWP for L1 measurement;

BWP switch configuration information.

The meaning of the BWP configuration information may be referred to the description of the foregoing embodiments.

Step 202, the network device configures the terminal to perform BWP handover.

Here, the network device configuring the terminal for BWP switching may be understood as that the network device configuring the terminal switches from BWP for measurement to BWP for non-measurement, or from BWP for non-measurement to BWP for measurement, etc.

Optionally, the network device may receive the auxiliary information sent by the terminal, and perform BWP handover according to the auxiliary information. The meaning of the auxiliary information may refer to the description of the foregoing method embodiment.

Optionally, if the network device determines that the link quality meets the BWP handover condition according to one or more of the following information, the network device configures the terminal to perform BWP handover:

quality of uplink signal, CQI reported by the terminal, and measurement result reported by the terminal.

For example, if it is determined according to the above information that the link quality is lower than the threshold preset by the network device, the network device configures the terminal to perform BWP handover. For example, it is possible to switch to BWP for measurement or BWP including SSB.

Optionally, in an embodiment of the present application, the network device may further send one or more of the following information to the terminal:

The meaning of the third information and the threshold information may refer to the description of the foregoing method embodiment.

In order to solve the above problems, an embodiment of the present application provides an information processing method. In the embodiment of the application, the network device sends BWP configuration information to the terminal. Wherein, the BWP configuration information may include:

first information indicating information of BWP for L1 measurement;

BWP switch configuration information.

Assume that there are a total of 4 BWP's, each: BWP0, BWP1, BWP2, BWP3, wherein BWP0 is initial BWP (initial BWP) and the terminal current active BWP (active BWP) is BWP1.

The process may include:

s1: the network device transmits BWP configuration information, including information of one or more BWP that can be used for the L1-related measurement, to the terminal. Wherein the L1-related measurement comprises an L1 RSRP/RSRQ/SINR measurement, and/or a radio link monitoring, and/or a beam failure detection, etc. Wherein which one or more BWP may be used for the L1 related measurement may be indicated by one or more of the following:

(1) Displaying an indication: let BWP3 be the BWP for measurement. A specific implementation manner may be that when the BWP configuration is performed, the network device adds indication information, and if the configuration includes the indication information or the indication information is true, the BWP3 is indicated as the BWP for measurement; if the indication information is not included in the configuration or is false, it means that the BWP3 is not used for measurement.

(2) The hidden indication: the network device includes configuration information, in particular, the configuration of the reference signal, in the configuration of BWP3 to monitor beam failure and/or radio link failure. That is, if the configuration of BWP3 includes configuration information for monitoring beam failure and/or radio link failure, it means that the BWP3 is the BWP for measurement.

S2: the terminal transmits the auxiliary information to the network device. Specifically, the terminal sends the switching information for switching the BWP to the network device, specifically including:

the target BWP ID of the handover, in this embodiment BWP 3;

the reason (cause) value of the BWP is to perform the L1-related measurement.

S4: the network device receives the assistance information of the terminal, switches the terminal to BWP3, and at the same time decides when the terminal can be switched back to non-measured BWP (BWP 0, BWP1, BWP 2) based on the time window.

The process may include:

S2: the terminal sends auxiliary information to the network device, specifically, the terminal sends switching information for switching BWP to the network device, which may specifically include:

the target BWP ID of the handover, in this embodiment BWP 3;

the reason (cause) value of the BWP is to perform the L1-related measurement.

S3: the network device receives the auxiliary information of the terminal and switches the terminal to BWP 3.

S4: the terminal transmits assistance information to the network device including the handover information of the BWP, in particular, the reason for the handover BWP, because the L1-related measurement is completed.

S5: the network device receives the assistance information of the terminal and switches the terminal back to a non-measured BWP, e.g. BWP1.

In one embodiment of the present application, BWP handover may be reported based on terminal measurements. Assume that there are a total of 4 BWP's, each: BWP0, BWP1, BWP2, BWP3, wherein BWP0 is initial BWP (initial BWP) and the terminal current active BWP (active BWP) is BWP1.

The process may include:

S2: the network device configures the event to the terminal, and the threshold and timer information needed by the event correspond to the event, and the embodiment of the application takes the following events as examples:

event 1: the serving cell is worse than the absolute threshold (RSRP 1) for a certain time (timer T1)

Event 2: the serving cell is worse than the relative threshold (delta RSRP 1) for a certain time (timer T2)

Event 3: the serving cell is better than the absolute threshold (RSRP 2) for a certain time (timer T3)

S5: the terminal performs L1 related measurement on BWP3, and when the measurement result satisfies event 3 and event 4, the measurement report of the terminal is triggered.

S6: the network device receives the measurement result reported by the terminal and switches the terminal back to BWP1.

In the above embodiment, the BWP switching based on the auxiliary information and the measurement report may be used in combination, for example, the auxiliary information is used when switching to the measurement BWP, and the measurement report is used when switching back to the non-measurement BWP; or vice versa.

For example, the network device may determine to switch the terminal onto BWP3 according to the assistance information of the terminal; and determining to switch the terminal to the non-measured BWP (BWP 0, BWP1, BWP 2) according to the measurement result reported by the terminal.

In one embodiment of the present application, BWP handover is performed based on base station measurements or implementations. Assume that there are a total of 4 BWP's, each: BWP0, BWP1, BWP2, BWP3, wherein BWP0 is initial BWP (initial BWP) and the terminal current active BWP (active BWP) is BWP1.

The process may include:

S2: the network equipment judges the link quality through the quality of the uplink signal, the CQI reported by the terminal, the measurement result reported by the terminal and other information. When the link quality is below a threshold predetermined by the network device, the terminal is switched to BWP3 for measurement.

S3: the terminal transmits assistance information to the network device including the handover information of the BWP, in particular, the reason for the handover BWP, because the L1-related measurement is completed.

S4: the network device receives the auxiliary information of the terminal, and switches the terminal back to BWP1 when the network device side determines that the link quality is higher than the threshold predetermined by the network device side.
