[0001] Divisional Application Instructions
[0002] This application is a divisional application of Chinese Patent Application No. 201880001865.6, filed on August 17, 2018, entitled "Method and Apparatus for Determining Channel Occupancy Information". Technical Field
[0003] This disclosure relates to the field of communication technology, and more specifically, to a method for determining channel occupancy information, a device for determining channel occupancy information, an electronic device, and a computer-readable storage medium. Background Technology
[0004] To expand the frequency bands available for communication, LAA (License Assisted Access) technology has been proposed, which uses unlicensed spectrum for auxiliary access.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0041] Figure 1This is a schematic flowchart illustrating a method for determining channel occupancy information according to an embodiment of this disclosure. The method for determining channel occupancy information shown in this embodiment can be applied to user equipment, wherein the user equipment can be a mobile phone, tablet computer, wearable device, etc., and the user equipment can communicate with a base station, for example, it can communicate with the base station based on NR technology.
[0042] like Figure 1 As shown, the method for determining the channel occupancy information may include the following steps:
[0043] In step S11, the identification information of the measurement object is determined according to the first indication information sent by the base station.
[0044] In one embodiment, the base station may send first indication information to the user equipment. The first indication information may carry identification information of the measurement object, wherein the identification information of the measurement object has a corresponding relationship with the beam. For example, the identification information of the measurement object may be an index of the Synchronization Signal Block (SSB) or an identifier of the Channel State Information Reference Signal (CSI-RS). The CSI-RS may be an NZP (non-zero power) CSI-RS.
[0045] The base station can send only the index of the synchronization signal block, or only the identifier of the channel state information reference signal, or both. The specific content sent to the user equipment as the identifier of the measurement object can be configured as needed.
[0046] In addition, the first indication information sent by the base station and the method of sending the first indication information may differ depending on the user equipment in different states.
[0047] For example, for a user equipment in an idle state, there is no communication connection between the user equipment and the base station. Therefore, the base station can send the first indication information by broadcasting. The identification information of the measurement object carried in the first indication information can be the identification of the synchronization signal block index or the channel state information reference signal.
[0048] For example, for a user equipment in a connected state, there is a communication connection between the user equipment and the base station. Therefore, the base station can send a first indication information to the user equipment in a targeted manner. For example, the first indication information can be sent in the form of a Radio Resource Control (RRC) message. The identification information of the measurement object carried in the first indication information can be the identifier of the channel state information reference signal or the index of the synchronization signal block.
[0049] In step S12, the target beam corresponding to the identification information of the measurement object is determined according to the pre-stored correspondence between the identification information of the measurement object and the beam.
[0050] In one embodiment, there is a correspondence between the identification information of the measurement object and the beam. The user equipment can store the correspondence in advance. The identification information of one measurement object can correspond to one beam or multiple beams.
[0051] In step S13, the first strength information of the signal received on the target beam is measured.
[0052] In one embodiment, the strength information can be RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), or RSSI (Received Signal Strength Indicator). The specific measurement of RSRP, RSRQ, or RSSI can be chosen as needed.
[0053] For example, when measuring channel occupancy information, if RSSI is selected, it can be performed when the base station is not transmitting signals. The received signals are mainly interference signals within the angle corresponding to the target beam.
[0054] In step S14, channel occupancy information is determined based on the first strength information.
[0055] In one embodiment, the user equipment can transmit the intensity information measured once as channel occupancy information to the base station, or it can transmit the intensity information measured multiple times as channel occupancy information to the base station. It can also further process the intensity information measured multiple times, for example, comparing the intensity information measured multiple times with a preset threshold, determining the intensity information that is greater than the preset threshold, and calculating the ratio of the intensity information greater than the preset threshold to the number of the multiple intensity information as the channel occupancy information.
[0056] In step S15, the channel occupancy information is sent to the base station, wherein the channel occupancy information is marked as being associated with the identification information of the measurement object.
[0057] According to embodiments of this disclosure, channel occupancy information can be determined on the beam corresponding to the identification information of the measurement object indicated by the base station, and the channel occupancy information sent to the base station can be associated with the identification information of the measurement object. This allows the base station to determine the beam where the channel occupancy information measured by the user equipment is located based on the identification information of the measurement object associated with the channel occupancy information when it receives the channel occupancy information. This facilitates the base station in determining the channel status of the channel corresponding to the beam, and helps the base station to reasonably schedule the channel on the beam for the user equipment, thereby avoiding the direction corresponding to the beam with greater interference, so as to improve the data throughput of the user equipment.
[0058] It should be noted that the embodiments of this disclosure can be applied to LAA or NR unlicensed spectrum technologies, for example, to determine whether the channel of the unlicensed spectrum on the target beam is idle based on channel occupancy information during LBT. Of course, the embodiments described in this disclosure can also be applied to other scenarios as needed.
[0059] Figure 2 This is a schematic flowchart illustrating another method for determining channel occupancy information according to embodiments of the present disclosure. Figure 2 As shown, in Figure 1 Based on the illustrated embodiment, the method further includes:
[0060] In step S16, before measuring the first intensity information of the signal received on the target beam, the second intensity information of the measured object received based on multiple alternative beams is recorded; in this case, one measured object can correspond to multiple alternative beams, that is, the measured object can be received on multiple alternative beams, so in step S12, multiple beams can be determined as alternative beams based on the received measured object.
[0061] The measurement of the first intensity information of the signal received on the target beam includes:
[0062] In step S131, the candidate beam corresponding to the measurement object with the largest second intensity information is determined as the target beam;
[0063] In step S132, first intensity information of the signal received on the target beam is measured.
[0064] In one embodiment, before measuring the first intensity information of the signal received on the target beam, the user equipment may receive the measurement object on multiple alternative beams and record the second intensity information of the received measurement object. The first signal strength and the second signal strength may be different parameters, for example, the first signal strength is RSSI and the second signal strength is RSRP or RSRP; or the first signal strength and the second signal strength may be the same parameter, for example, both are RSRP.
[0065] In one embodiment, when measuring the second strength information, the base station can transmit a specified measurement object at a specified time. Taking a synchronization signal block as an example, the user equipment uses multiple alternative beams to receive the synchronization signal block at the specified time. If the RSRP or RSRQ of the synchronization signal block is the highest when using a certain beam, it indicates that the channel conditions for receiving the synchronization signal block using that receiving beam are the best, and this beam is then determined as the target beam corresponding to the synchronization signal block. When measuring the first strength information, it is for channel detection, i.e., determining whether other devices are occupying the unlicensed spectrum corresponding to the detected channel on the target beam corresponding to the synchronization signal block. At this time, the base station does not transmit the synchronization signal block; the user equipment mainly detects the energy of signals transmitted by other devices. Therefore, the first strength information measures RSSI. When the RSSI is higher than a threshold, it indicates that other devices are using this unlicensed spectrum nearby. The ratio of the number of RSSIs higher than the threshold to the total number of detected RSSIs can then be used as channel occupancy information.
[0066] By determining the second strength information of the measured object recorded on multiple candidate beams, the measured object corresponding to the largest second strength information can be identified. The user equipment (UE) then receives the strongest signal on the candidate beam corresponding to that measured object. This candidate beam is then used as the target beam, and the first strength information of the received signal is measured on the target beam. This allows the base station to receive the channel occupancy information determined by the UE on the beam with the strongest received signal. The base station can then perform channel scheduling based on the beam with the strongest received signal, ensuring that the UE receives signals on that beam and maximizing its communication quality.
[0067] Figure 3 This is a schematic flowchart illustrating yet another method for determining channel occupancy information according to embodiments of the present disclosure. Figure 3 As shown, in Figure 1 Based on the illustrated embodiment, the method further includes:
[0068] In step S17, before measuring the first strength information of the signal received on the target beam, the timing of the measurement is determined according to the second indication information sent by the base station; wherein, step S17 can be as follows: Figure 3 As shown, step S17 is executed after step S11. The execution order of step S17 can also be adjusted as needed. For example, it can be executed before step S11 or simultaneously with step S11.
[0069] The measurement of the first intensity information of the signal received on the target beam includes:
[0070] In step S133, at the measurement timing, the first strength information of the received signal is measured on the target beam.
[0071] In one embodiment, the base station can instruct the user equipment to measure the first strength information of the received signal on the target beam through the second indication information, so that the user equipment can measure the first strength information of the received signal on the target beam at the measurement time. The measurement time can be a time period, that is, the user equipment measures the first strength information of the received signal on the target beam only during the time period. Accordingly, the user equipment can avoid wasting its resources by measuring the first strength information of the received signal on the target beam too much.
[0072] Figure 4 This is a schematic flowchart illustrating yet another method for determining channel occupancy information according to embodiments of the present disclosure. Figure 4 As shown, in Figure 1 Based on the illustrated embodiment, the measurement of the first strength information of the signal received on the target beam further includes:
[0073] In step S134, multiple first intensity information measured at the measurement timing is recorded;
[0074] The step of determining channel occupancy information based on the first strength information includes:
[0075] In step S141, the ratio of the number of first intensity information greater than a preset threshold to the number of the plurality of first intensity information is calculated as the channel occupancy information.
[0076] In one embodiment, the user equipment can measure the first strength information of the received signal multiple times on the target beam during the measurement time. For example, N first strength information are measured. For each measured first strength information, the first strength information can be compared with a preset threshold. For example, if M of the N first strength information are greater than the preset value, then M / N can be calculated as channel occupancy information and transmitted to the base station.
[0077] Since the channel state can change, if the channel occupancy information is determined based on the first strength information obtained from a single measurement, the measurement result cannot accurately reflect the channel occupancy status. However, the quantity ratio is calculated based on multiple measurement results, which can better reflect the channel occupancy status. Therefore, using the quantity ratio as channel occupancy information allows the base station to more accurately determine the channel occupancy status.
[0078] Optionally, the identification information of the measurement object includes at least one of the following:
[0079] The index of the synchronization signal block, and the identifier of the channel state information reference signal.
[0080] Figure 5 This is a schematic flowchart illustrating another method for determining channel occupancy information according to an embodiment of this disclosure. The method for determining channel occupancy information shown in this embodiment can be applied to a base station that can communicate with user equipment, for example, it can communicate with user equipment based on NR technology, wherein the user equipment can be a mobile phone, tablet computer, wearable device, etc.
[0081] like Figure 5 As shown, the method for determining the channel occupancy information may include the following steps:
[0082] In step S51, a first indication information is sent to the user equipment, wherein the first indication information is used to indicate the identification information of the measurement object, so that the user equipment measures the first strength information of the received signal on the target beam corresponding to the identification information of the measurement object, and determines the channel occupancy information based on the first strength information;
[0083] In step S52, the channel occupancy information and the identification information of the measurement object associated with the channel occupancy information are received from the user equipment.
[0084] According to embodiments of this disclosure, a base station can indicate the identification information of a measurement object to a user equipment (UE), thereby determining channel occupancy information on the beam corresponding to the identification information of the measurement object indicated by the UE, and associating the channel occupancy information sent to the base station with the identification information of the measurement object. This allows the base station to determine the beam where the channel occupancy information measured by the UE is located based on the identification information of the measurement object associated with the channel occupancy information when it receives the channel occupancy information. This facilitates the base station in determining the channel status of the channel corresponding to the beam, enabling the base station to rationally schedule channels on the beam for the UE, thereby avoiding directions corresponding to beams with greater interference and improving the data throughput of the UE.
[0085] Figure 6This is a schematic flowchart illustrating yet another method for determining channel occupancy information according to embodiments of the present disclosure. Figure 6 As shown, in Figure 5 Based on the illustrated embodiment, the method further includes:
[0086] In step S53, before receiving the channel occupancy information and the identification information of the measurement object associated with the channel occupancy information sent by the user equipment, a second indication information is sent to the user equipment, wherein the second indication information is used to indicate the measurement timing so that the user equipment measures the first strength information of the received signal on the target beam corresponding to the identification information of the measurement object at the measurement timing.
[0087] In one embodiment, the base station can instruct the user equipment to measure the first strength information of the received signal on the target beam through the second indication information, so that the user equipment can measure the first strength information of the received signal on the target beam at the measurement time. The measurement time can be a time period, that is, the user equipment measures the first strength information of the received signal on the target beam only during the time period. Accordingly, the user equipment can avoid wasting its resources by measuring the first strength information of the received signal on the target beam too much.
[0088] Optionally, the identification information of the measurement object includes at least one of the following:
