[0027] Referring to Fig. 1, a structural schematic diagram of a wireless communication system provided in an embodiment of the present disclosure is shown. As shown in Fig. 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include several terminals 11 and several base stations 12.

[0028] The terminal 11 may be a device that provides voice and / or data connectivity to a user. The terminal 11 may communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 11 may be an Internet of Things terminal, such as a sensor device, a mobile phone (also called a "cellular" phone), and a computer with an Internet of Things terminal, such as a fixed, portable, pocket, handheld, computer-embedded, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Or, the terminal 11 may be an equipment of an unmanned aerial vehicle. Alternatively, the terminal 11 may be an in-vehicle device, for example, an electronic control unit having a wireless communication function, or a wireless communication device with an external electronic control unit, or the terminal 11 may be a roadside device, for example, a street lamp, a traffic light, or other roadside device having a wireless communication function.

[0029] The base station 12 may be a network side device in a wireless communication system. Here, the wireless communication system may be the 4th generation mobile communication (4G) system, also called a Long Term Evolution (LTE) system, or the wireless communication system may be a 5G system, also called a new radio (NR) system or a 5G NR system. Or the wireless communication system may be a system that is a next generation of the 5G system. Here, the access network in the 5G system may be called a New Generation-Radio Access Network (NG-RAN). Or it may be an MTC system.

[0030] The base station 12 may be an evolutionary base station (eNB) adopted in a 4G system. Or, the base station 12 may be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DU). The centralized unit is set with a packet data convergence protocol (PDCP) layer, a radio link control protocol (RLC) layer, and a media access control (MAC) layer protocol stack, and the distributed unit is set with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation form of the base station 12.

[0031] A radio connection can be established between the base station 12 and the terminal 11 via a radio air interface. In different embodiments, the radio air interface is a radio air interface based on a fourth generation mobile communication network technology (4G) standard, or the radio air interface is a radio air interface based on a fifth generation mobile communication network technology (5G) standard, for example the radio air interface is a new air interface, or the radio air interface may be a radio air interface based on a further next generation mobile communication network technology standard of 5G.

[0032] In some embodiments, an E2E (End to End) connection can be established between the terminals 11, for example in vehicle to everything (V2X) communication scenarios such as V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication.

[0033] In some embodiments, the wireless communication system may further include a network management device 13 .

[0034] The base stations 12 are each connected to a network management device 13. The network management device 13 may be a core network device in a wireless communication system, for example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC) network. Or the network management device may be another core network device, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation form of the network management device 13 is not limited in the embodiment of the present invention.

[0035] An execution subject according to the embodiment of the present disclosure includes, but is not limited to, a user equipment (UE) such as a mobile phone terminal that performs wireless communication by adopting a cellular mobile communication network technology.

[0036] One application scenario of the embodiment of the present disclosure is a UE uplink channel such as REDCAP, such as message 3 (Msg 3) in four-stage random access, a physical uplink control channel (PUCCH), a unicast physical uplink shared channel (PUSCH), etc., which needs to perform coverage extension in certain situations.

[0037] The specific PRACH resource can be divided and used by the UE to indicate the coverage extension means that the base station should use in subsequent uplink transmissions. Alternatively, the terminal may request the network to further extend the coverage. The network side can estimate the quality of the channel in which the UE is located based on the detected PRACH resource or further understand the extent of coverage extension requested by the UE.

[0038] As shown in Table 1, the UE can determine the corresponding PRACH resource according to the RSRP threshold range in which the RSRP value, which is the measurement result of the SS-RSRP, falls.

[0039] [Table 1]

[0040] In current networks, different types of UEs exist simultaneously. For example, enhanced mobile broadband (eMBB) terminals and Redcap terminals exist simultaneously in the network. The number of receiving antennas of different types of UEs is different. For example, one receiving antenna (1Rx), two receiving antennas (2Rx), and four receiving antennas (4Rx) exist simultaneously in the network. When measuring the UE RSRP with different receiving antennas, the RSRP measured for a UE with many antennas is generally high, i.e., RSRP-1Rx. <RSRP-2Rx<RSRP-4Rxである。

[0041] UEs with different receiving antennas may each have only one Tx, that is, UEs with different receiving antennas have the same uplink coverage performance in practice. If different UEs use different numbers of Rx to perform RSRP measurements and then select PRACH resources based on the measured RSRP to characterize coverage extension demand, it is not possible to characterize accurate coverage extension demand in practice. For example, the RSRP measured with 4 Rx is higher than the RSRP measured with 1 Rx, so according to the current rules, the PRACH resources selected by both are different, and the coverage extension demands characterized by the PRACH resources are also different. As a result, the uplink coverage extension degree of the 4Rx terminal is insufficient, or the uplink coverage of the 1Rx terminal is overextended.

[0042] Therefore, for UEs with different receive antennas, how to select PRACH resources and more accurately characterize the coverage extension demand is an urgent problem to be solved.

[0043] As shown in FIG. 2, the present exemplary embodiment provides a resource configuration method, which can be applied to a UE of a wireless communication, and includes step 201 of determining a PRACH resource based on the number of antennas of the UE and a channel measurement result.

[0044] Here, the steps of the method of this embodiment may be performed by a UE, such as a Redcap or eMBB terminal.

[0045] Different PRACH resources are used to indicate different coverage extension levels to the base station, i.e., different PRACH resources can indicate different coverage extension levels to the base station. The base station can determine the coverage extension level of the UE's uplink transmission based on the PRACH resources employed by the UE, including but not limited to random access messages such as Msg 3, uplink transmissions employing PUCCH and / or PUSCH resources to transmit information, etc.

[0046] The coverage extension level may be an uplink coverage extension level, for example, a coverage extension level carried by Msg 3, and / or a coverage extension level carried by employing PUCCH resources and / or PUSCH resources.

[0047] The UE may employ different PRACH resources to indicate different coverage extension levels to the base station.

[0048] The UE may employ the receive antenna to perform channel measurement to obtain a channel measurement result. The UE may employ the transmit antenna to transmit uplink data. A coverage extension level is associated with the transmit antenna.

[0049] In one embodiment, the different PRACH resources may include different time domain resources, and / or different frequency domain resources, and / or different random access preambles, and / or the like.

[0050] Here, the channel measurement result may be a measurement result obtained by the UE performing channel measurement. The UE can obtain the channel measurement result by measuring a downlink signal of the base station, such as a Tracking Reference Signal (TRS) and / or a Channel State Information Reference Signal (CSI-RS). The number of antennas of the UE may include the number of antennas for channel measurement.

[0051] In one embodiment, the channel measurements include a Reference Signal Received Power (RSRP) value.

[0052] The RSRP value is a key parameter of radio signal strength and is the average value of the signal power received on all resource elements (REs) carrying reference signals in a symbol. Different RSRP values ​​may be obtained by performing RSRP measurements via different numbers of antennas. The antennas for RSRP measurements may be the receiving antennas of the UE.

[0053] In the prior art, the UE determines the PRACH resource to indicate the coverage extension level based on the measured RSRP value without considering the number of antennas that perform RSRP measurement, and the indicated coverage extension level does not meet the actual coverage extension demand.

[0054] In this embodiment, the PRACH resource indicating the coverage extension level can be jointly determined based on the number of antennas performing RSRP measurement and the RSRP value.

[0055] Since the RSRP values ​​obtained by performing RSRP measurements using different numbers of antennas are different, they cannot accurately reflect the demand for coverage extension, so that the coverage extension level associated with the determined PRACH resource can meet the actual demand by compensating for the RSRP values ​​obtained by performing RSRP measurements using different numbers of antennas and / or adjusting the RSRP threshold range for determining the PRACH resource.

[0056] For example, the RSRP value measured by a UE having four receive antennas is higher than the RSRP value measured by a UE having one receive antenna, so that according to the rules of the related art, the PRACH resources selected for the two RSRP values ​​are different, and the coverage extension demands associated with the PRACH resources are also different. In general, it may ultimately cause a lower level of coverage extension to be selected for a UE with a higher RSRP value, and a higher level of coverage extension to be selected for a UE with a lower RSRP value. Assuming that two UEs both have the same number of transmit antennas and are used for uplink transmission, when performing RSRP measurement, the number of receive antennas for measuring the RSRP value is not distinguished, and the PRACH resource is determined and caused only based on the RSRP value, resulting in an insufficient degree of uplink coverage extension for a UE having four receive antennas, or an overextended degree of uplink coverage for a UE having one receive antenna.

[0057] Here, the measured RSRP value can be compensated based on the number of antennas performing RSRP measurement, and the coverage extension level determined based on the compensated RSRP value can be matched to the actual demand for uplink coverage. Also, the RSRP threshold ranges corresponding to different PRACH resources can be adjusted according to the number of antennas performing RSRP measurement, and the coverage extension level determined based on the RSRP values ​​measured by different numbers of antennas can be matched to the actual demand for uplink coverage.

[0058] In this way, the PRACH resource corresponding to the coverage extension level is jointly determined based on the number of UE antennas and the channel measurement result, the deviation caused by determining the coverage extension demand according to only the channel measurement result is reduced, and the accuracy of selecting the PRACH resource for indicating the coverage extension is further improved, and the problem of signal transmission instability caused by adopting a coverage extension level that is too low or high power consumption caused by adopting a coverage extension level that is too high is reduced.

[0059] In one embodiment, the step of determining a PRACH resource based on the number of antennas of the UE and a channel measurement result includes the steps of: determining to employ one antenna to perform channel measurement; and determining the PRACH resource based on the channel measurement result obtained in the channel measurement.

[0060] Here, the channel measurement may be an RSRP measurement, and the channel measurement result may be an RSRP value, which may be specified in a manner such as a communication protocol. When the UE uses the RSRP value to determine the PRACH resource and further indicates a coverage extension demand, the UE may perform the RSRP measurement using only one antenna.

[0061] UEs that perform RSRP measurement through one antenna and have different numbers of antennas can adopt similar signal reception capabilities to determine the RSRP value. For the same signal strength, the RSRP values ​​measured by RSRP are closer, and a unified standard can be adopted, that is, the RSRP threshold range determines the PRACH resource indicating the coverage extension level. The determined coverage extension level can further meet the actual coverage extension demand.

[0062] In one embodiment, the step of determining a PRACH resource based on the number of antennas and channel measurement results of the UE includes the steps of determining a threshold range of a corresponding channel measurement result based on the number of antennas for channel measurement, and determining a PRACH resource from a PRACH resource set corresponding to the threshold range of the channel measurement result in which the measured channel measurement result is located, where one PRACH resource set includes at least one PRACH resource.

[0063] The same UE or different UEs may employ different numbers of antennas to perform RSRP measurements. Corresponding RSRP threshold ranges can be set for different numbers of antennas. The RSRP threshold ranges corresponding to different numbers of antennas are set to be the same or different. The same number of antennas may have multiple RSRP threshold ranges, and the PRACH resource sets corresponding to different RSRP threshold ranges may be different. The coverage extension levels associated with the PRACH resources in the same PRACH resource set are the same. Therefore, the coverage extension level demands corresponding to different RSRP threshold ranges are different.

[0064] The UE may determine an RSRP threshold range based on the number of antennas for RSRP measurement, and may determine a PRACH resource indicating a coverage extension level based on the RSRP threshold range in which the measured RSRP value falls.

[0065] In this way, for different numbers of antennas, a corresponding RSRP threshold range can be set, and then a measured RSRP value can be compared with the RSRP threshold range to determine a correct PRACH resource, i.e., a correct coverage extension level can be determined, thereby reducing the problem of signal transmission instability caused by adopting a coverage extension level that is too low, or high power consumption caused by adopting a coverage extension level that is too high.

[0066] In one embodiment, for different numbers of antennas, the channel measurement threshold ranges corresponding to the same PRACH resource set are different.

[0067] Here, different RSRP threshold ranges can be used for different numbers of antennas for RSRP measurement, and the same number of antennas can have multiple RSRP threshold ranges corresponding to different PRACH resource sets, respectively.

[0068] For example, as shown in Table 2, when one antenna is employed to perform RSRP measurement, the RSRP threshold ranges corresponding to three PRACH resource sets (PRACH set#1, PRACH set#2, and PRACH set#3) are R1-R2, R2-R3, and >R3, respectively. When two antennas are employed to perform RSRP measurement, the RSRP threshold ranges corresponding to three PRACH resource sets are R1'-R2', R2'-R3', and >R3', respectively. When four antennas are employed to perform RSRP measurement, the RSRP threshold ranges corresponding to three PRACH resource sets are R1''-R2'', R2''-R3'', and >R3'', respectively. Here, R1, R2, R3, R1', R2', R3', R1'', R2'', and R3'' respectively indicate RSRP thresholds.

[0069] [Table 2]

[0070] In this way, different RSRP threshold ranges are adopted for different numbers of antennas, so as to reduce the impact of differences in RSRP values ​​measured by different numbers of antennas on PRACH resource determination, and improve the accuracy of PRACH resource determination.

[0071] In one embodiment, the channel measurement threshold ranges corresponding to different numbers of antennas are the same, and the PRACH resource sets corresponding to the channel measurement threshold ranges corresponding to different numbers of antennas are different.

[0072] Here, the same RSRP threshold range can be used for different numbers of antennas for RSRP measurement, and the PRACH resources corresponding to the same RSRP threshold range for different numbers of antennas are different. The same number of antennas can correspond to different PRACH resource sets corresponding to multiple RSRP threshold ranges, respectively.

[0073] Exemplarily, as shown in Table 3, when performing RSRP measurement using one antenna, two antennas, or four antennas, the RSRP threshold ranges are all <R1, R1 to R2, and >R2. However, for different numbers of antennas, the PRACH resource sets corresponding to the same RSRP threshold range are different. That is, even if the RSRP measured with different numbers of antennas has the same RSRP threshold, the determined PRACH resource sets are different, that is, the selected coverage expansions are different.

[0074]

Table 3

[0075] Thus, for different numbers of antennas, the same RSRP threshold range corresponds to different PRACH resources. To avoid differentiating the number of antennas, by adopting the same PRACH resource selection criterion, the problem that the generated PRACH resource selection is inaccurate is reduced, and the accuracy of determining the PRACH resources is improved.

[0076] In one embodiment, the threshold ranges of the channel measurement results corresponding to different numbers of antennas are different, and the PRACH resource sets corresponding to the threshold ranges of the channel measurement results of different numbers of antennas are different.

[0077] Here, for different numbers of antennas for RSRP measurement, different RSRP threshold ranges can be used, and the PRACH resources corresponding to the RSRP threshold ranges of different numbers of antennas are different.

[0078] Exemplarily, as shown in Table 4, when performing RSRP measurement using one antenna, two antennas, or four antennas, the RSRP threshold ranges are all different, and the PRACH resources corresponding to each RSRP threshold range may also be different.

[0079] [Table 4]

[0080] In this way, independent RSRP threshold ranges and corresponding PRACH resources for each RSRP threshold range are established for different numbers of antennas, which improves the directivity of PRACH resource selection and further improves the accuracy of PRACH resource selection.

[0081] Below, one specific example is provided in conjunction with any of the above embodiments.

[0082] This example provides four different methods to be used to determine the PRACH resource.

[0083] In method 1, which is predefined by the protocol, the terminal uses RSRP to determine the PRACH resource and further indicates the coverage extension level, and then performs measurement using only 1Rx.

[0084] In method 2, as shown in Table 2, different receive antennas use different RSRP threshold ranges when the terminal determines the PRACH resources and / or determines the uplink coverage extension level it needs to perform.

[0085] In method 3, as shown in Table 3, when a terminal determines a PRACH resource and / or determines an uplink coverage extension level that needs to be performed, the PRACH resources used by terminals of different receive antennas with the same RSRP threshold range are different.

[0086] In method 4, as shown in Table 4, when the terminal determines the PRACH resource and / or determines the uplink coverage extension level that needs to be performed, the RSRP threshold ranges and corresponding PRACH resources used by the terminals of different receive antennas are all different.

[0087] According to this embodiment, a resource configuration apparatus is further provided and can be applied to a UE, and as shown in FIG. 3, the apparatus 100 includes a determination module 110 for determining a PRACH resource based on the number of antennas of the UE and a channel measurement result.

[0088] In one embodiment, the determination module is used for determining to employ one antenna to perform channel measurement, and determining the PRACH resource based on a channel measurement result obtained in the channel measurement.

[0089] In one embodiment, the determination module 110 is used for determining a threshold range of a corresponding channel measurement result based on the number of antennas for channel measurement, and determining a PRACH resource from a PRACH resource set corresponding to the threshold range of the channel measurement result in which the measured channel measurement result is located, where one PRACH resource set includes at least one PRACH resource.

[0090] In one embodiment, for different numbers of antennas, the channel measurement threshold ranges corresponding to the same PRACH resource set are different.

[0091] In one embodiment, the channel measurement threshold ranges corresponding to different numbers of antennas are the same, and the PRACH resource sets corresponding to the channel measurement threshold ranges corresponding to different numbers of antennas are different.

[0092] In one embodiment, the channel measurement threshold ranges corresponding to different numbers of antennas are different, and the PRACH resource sets corresponding to the channel measurement threshold ranges of different numbers of antennas are different.

[0093] In one embodiment, the channel measurements include a Reference Signal Received Power (RSRP) value.
