Description

Technical Field

[0001] The present disclosure relates to, but is not limited to, the field of communication technologies, and particularly relates to an information processing method, apparatus, communication device, and storage medium. Background Art

[0002] With the rapid growth of data, the available licensed frequency bands tend to be saturated, resulting in a serious spectrum shortage problem. To solve the spectrum shortage problem, a new concept, i.e., unlicensed spectrum, is introduced. The unlicensed spectrum refers to the spectrum that can be used without authorization from the competent authority under the condition of meeting the regulatory rules. Since the unlicensed frequency band has the characteristic of spectrum sharing, in order to ensure fair coexistence among nodes within the system and with other access technologies, the New Radio in Unlicensed Spectrum (NR-U) adopts a Listen Before Talk (LBT)-based channel access mechanism, that is, the sending end needs to perform channel idle detection before transmission and can occupy the channel only after successful detection. And for high data rate communication, the NR frequency band is extended from 52.6 GHz to up to 71 GHz. In the high frequency range, NR-U / Wi-Fi always requires the use of beamforming to overcome the large propagation loss. Therefore, directional LBT should be adopted for directional transmission.

[0003] To improve the LBT-based channel access mechanism, a method based on the Channel Occupancy Time (COT) of directional LBT is proposed. If multiple User Equipments (UEs) share a COT initiated by a 5G gNode B (gNB), the beam directions and beam widths from each UE to the gNB may be different. Therefore, a method to ensure fairness of COT sharing for other Radio Access Technologies (RATs) and uncoordinated networks should be studied.

[0004] NR or NR-U supports Multi-User Multiple-Input Multiple-Output (MU-MIMO), that is, the base station can schedule multiple UEs in the same time-frequency domain resource. In this case, the mechanism for multiple UEs to share a COT needs to be discussed separately according to different refined scenarios, and there may be some problems in certain scenarios. For example, when multiple UEs share a COT, such as UE1, UE2, and UE3 sharing a COT, among which UE2 detects the channel as busy and fails in LBT. However, UE2 does not know the reason for the LBT failure and believes that it cannot upload data, thus losing the opportunity for transmission that could have been carried out, reducing the resource utilization rate of the COT.

As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of user equipments 110 and a plurality of base stations 120.

[0046] To better understand the technical solutions described in any embodiment of the present disclosure, first, a partial description of the shared frequency band resources of multiple UEs is given:

[0047] Currently, for high data rate communication, the NR frequency band can be extended from 52.6 GHz to up to 71 GHz and above. In the high frequency band range, NR-U / WiFi can require the use of beamforming to overcome the large propagation loss; for example, directional LBT can be used for directional transmission. If NR / NR-UE supports multi-user multiple input multiple output (MU-MIMO), that is, the base station can schedule multiple UEs in the same time-frequency domain resource; in this scenario, the mechanism for multiple UEs to share a frequency band resource needs to be discussed separately according to different refined scenarios. For example, in the application scenario shown in Figure 2 the following assumed conditions are proposed for this scenario:

[0048] (1) There are three UEs in the uplink (UL) direction, namely UE1, UE2, and UE3; these three UEs share a frequency band resource;

[0049] (2) The base station and these three UEs all use directional LBT for channel access;

[0050] (3) The beam direction and beam width between each of these three UEs and the base station may be different. Assume that the transmission beam range of UE2 is relatively large, and the transmission beam range of UE2 covers the transmission beam range of UE1; while the transmission beam range of UE3 is not within the transmission beam coverage of any UE, and the transmission beam direction of UE3 is basically the same as that of UE1.

[0051] (4) The time-frequency domain resources of UE1, UE2, and UE3 may have overlapping parts.

[0052] As above Figure 2 In the application scenario as described above, the beam direction and beam width of each UE with respect to the base station are not exactly the same; among them, the transmission beam range of UE1 is within the transmission beam range of UE2, and the transmission beam directions of UE1 and UE2 are basically the same. In this application scenario, UE1 is an important object prone to interference. Whether UE1 can transmit uplink data depends not only on the result of listening to the channel during its LBT, but also on more factors. The sharing of a frequency band resource by these three UEs here can be considered as these three UEs sharing a COT initiated by a base station.

[0053] For example, in one embodiment, the reasons for UE1 to detect the channel as busy and fail the LBT at least include the following two reasons:

[0054] Reason 1: Since the transmission beam coverage range of UE1 is within the transmission beam range of UE2, the uplink data transmission of UE2 will interfere with the LBT result of UE1; however, at this time, UE2 may not occupy the channel of UE1. In this application scenario, if there is only interference from the data transmission of UE2, the LBT result of UE1 is not credible, and at this time, UE1 can actually transmit uplink data on its own channel.

[0055] Reason 2: Since the uplink data transmission of UE3 occupies the channel of UE1, it will interfere with the LBT result of UE1. In this application scenario, UE1 cannot transmit uplink data, otherwise there will be a conflict with the uplink data transmission of UE3.

[0056] In the above application scenario, the uplink data transmission of UE2 can be considered as known interference, and the uplink data transmission of UE3 can be considered as unknown interference. Moreover, since the transmission beam range of UE1 as described above is within the transmission beam range of UE2, it can be considered that UE1 and UE2 are a coverage interference pair.

[0057] Thus, for UE1 as described above, it does not know whether it fails the LBT due to the above Reason 1 or Reason 2; UE1 cannot generate different behaviors for different failure reasons; thus, it will cause UE1 to think that it cannot transmit uplink data and may lose the opportunity to transmit that could have been carried out originally, reducing the utilization rate of the shared frequency band resource.

[0058] As Figure 3 shown, a method for information processing is provided. This method is executed by a first UE and includes:

[0059] Step S31: Receive first information sent by a network device, where the first information is related to the characteristic sequence of uplink data;

[0060] Step S32: Monitor data transmission on the shared frequency band resource, where the shared frequency band resource includes the frequency band resource shared by the first UE and the second UE;

[0061] Step S33: Determine whether uplink transmission can be performed on the shared frequency band resource according to the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource.

[0062] In one embodiment, both the first UE and the second UE can be various mobile terminals or fixed terminals. For example, both the first UE and the second UE can be but are not limited to mobile phones, computers, servers, wearable devices, game control platforms, or multimedia devices, etc.

[0063] In one embodiment, the network device includes: a base station. For example, the above step S31 can be: receiving the definition information sent by the base station.

[0064] In one embodiment, the base station can be an interface device for the UE to access the Internet. The base station can be various types of base stations; for example, 3G base stations, 4G base stations, 5G base stations, or other evolved base stations.

[0065] In other embodiments, the network device can also be a core network or a network side entity in a radio access network, etc.

[0066] In one embodiment, the first UE and the second UE share a shared channel. For example, the first UE and the second UE share the channel occupancy time. Another example is that the first UE and the second UE share a shared frequency band resource. Another example is that the first UE and the second UE share a shared time-frequency domain resource.

[0067] Here, two or more UEs can share a shared frequency band resource. For example, a first UE and a second UE share a shared frequency band resource; another example is that a first UE and multiple second UEs share a shared frequency band resource.

[0068] In one embodiment, the first UE and the second UE sharing a shared channel can be sharing the shared channel with the same base station.

[0069] In one embodiment, the first information is related to the characteristic sequence of the uplink data sent by the second UE. For example, the first information includes: indicating the characteristic sequence of the uplink data sent by the second UE, or any information used to determine the characteristic sequence of the uplink data sent by the second UE. For example, the first information can be the characteristic information of the DMRS of the uplink data sent by the second UE, etc.

[0070] In one embodiment, the first information includes but is not limited to at least one of the following:

[0071] Demodulation reference signal (Dedicated Reference Signal, DMRS) configuration information, which is used for the second UE to transmit DMRS according to the DMRS configuration information;

[0072] DMRS indication information, which is used to indicate the characteristic information after the joint coding of each DMRS configuration information.

[0073] In one embodiment, the DMRS configuration information includes but is not limited to at least one of the following:

[0074] Time-domain resource information of the time-domain resource for transmitting DMRS;

[0075] Frequency-domain configuration information of the frequency-domain resource for transmitting DMRS;

[0076] Indication information for indicating the transmission mode of transmitting DMRS;

[0077] Type information of DMRS; wherein, the type information of DMRS is used to indicate whether DMRS is pre-coded DMRS.

[0078] The DMRS here is the DRMS of the uplink data sent by the second UE. In one embodiment, the configuration information of MDRS and / or the DMRS indication information is the information used to indicate the characteristic sequence of the uplink data sent by the second UE. For example, the configuration information of DMRS and / or the DMRS indication information can be regarded as the prior information of the second UE sending uplink data.

[0079] Exemplarily, as Figure 4 shown, in a resource block (RB), it includes the time-domain resource of one time slot and 12 subcarriers in the frequency domain; wherein, one time slot has 14 symbols; wherein, one symbol and one subcarrier form a time-frequency domain resource unit (RE). Among them, the numbering order of the 14 symbols is from 0 to 13, for example, 0, 1, 2,... 12 and 14; the numbering order of the 12 subcarriers is 0 to 11, for example, 1, 1, 2,... 10 and 11. The DMRS configuration information here can be used to indicate the time-frequency domain resource information of transmitting DMRS; for example, indicating one or more resource blocks.

[0080] In one embodiment, the time-domain resource information includes at least one of the following:

[0081] Number of symbols; the number of symbols is used to indicate the number of DMRS symbols to be sent;

[0082] Symbol distribution information; the symbol distribution information is used to indicate the number of symbols continuously occupied by transmitting DMRS in the time domain;

[0083] Time domain start position; The time domain start position is used to indicate the position of the first symbol occupied by the DMRS in the time domain;

[0084] Symbol position; The symbol position is used to indicate the sequence of symbols occupied by the DMRS.

[0085] Exemplarily, the time domain resource information of the time domain resource for transmitting the DMRS includes the number of symbols. For example, as Figure 4 shown, the number of symbols indicates that the number of symbols for transmitting the DMRS is 1; Another example, as Figure 5 shown, the number of symbols is used to indicate that the number of symbols for transmitting the DMRS is 2.

[0086] Exemplarily, the time domain resource information of the time domain resource for transmitting the DMRS includes symbol distribution information. For example, as Figure 4 shown, the symbol distribution information includes: single symbol distribution information; wherein, the single symbol distribution information is used to indicate that the number of consecutive symbols occupied by the transmitted DMRS in the time domain is 1. Another example, as Figure 5 shown, the symbol distribution information includes: double symbol distribution information; wherein, the double symbol distribution information is used to indicate that the number of consecutive symbols occupied by the transmitted DMRS in the time domain is 2.

[0087] In other embodiments, the symbol distribution information can be "0", which is used to indicate that the number of consecutive symbols occupied by the transmitted DMRS in the time domain is 1; the symbol distribution information can be "1", which is used to indicate that the number of consecutive symbols occupied by the transmitted DMRS in the time domain is 2.

[0088] Exemplarily, the time domain resource information of the time domain resource for transmitting the DMRS includes the time domain start position. For example, as Figure 4 shown, the time domain start position is used to indicate that the position of the first symbol occupied by the DMRS is the 2nd symbol. Another example, as Figure 5 shown, the time domain start position is used to indicate that the position of the first symbol occupied by the DMRS is the 3rd symbol. In other embodiments, the time domain start position for indicating the position of the first symbol occupied by the transmitted DMRS can also be other symbols or symbols in other columns. For example, it can be the 1st symbol, the 4th symbol, or the 5th symbol, etc.

[0089] In other embodiments, the time domain start position can also refer to the time domain start position of the preamble DMRS. Among them, in 5G NR, the DMRS adopts a preamble design concept, and this DMRS can be called the preamble DMRS.

[0090] Exemplarily, the time domain resource information of the time domain resource for transmitting the DMRS includes the symbol position. For example, as Figure 4 shown, the symbol position is used to indicate that the sequence of symbols occupied by the DMRS is the 2nd column. Another example, as Figure 5As shown, the symbol position is used to indicate that the symbols occupied by the DMRS are the 3rd and 4th columns. Currently, in other embodiments, the symbol position can also indicate other column numbers of the symbols occupied by the DMRS.

[0091] Exemplarily, the time-domain resource position of the time-domain resource for transmitting the DMRS includes: the maximum number of symbols. For example, the maximum number of symbols can be the number of symbols in a time slot, such as 14 symbols. Of course, in other embodiments, the maximum number of symbols can be other numbers, such as 8, 10, or 3, etc.

[0092] In other embodiments, the first information can also be: the DMRS sequence. For example, the first information can be one or more DMRS sequences. In one embodiment, one DMRS sequence can indicate the time-domain resource information for transmitting the DMRS in a resource block.

[0093] Exemplarily, the frequency-domain configuration information of the frequency-domain resource for transmitting the DMRS can be the frequency-domain resource information of the frequency-domain resource for transmitting the DMRS. For example, as Figure 5 shown, the frequency-domain resource information can be the 0th and 1st subcarriers, and the 6th and 7th symbols.

[0094] Of course, in other embodiments, the frequency-domain configuration information of the frequency-domain resource for transmitting the DMRS can also be other frequency-domain configuration information, such as frequency-domain multiplexing mode information, etc.

[0095] In one embodiment, the indication information for indicating the transmission mode of the DMRS includes at least one of the following:

[0096] Frequency-domain multiplexing mode information, used to indicate the frequency-domain multiplexing mode for transmitting the DMRS;

[0097] Frequency hopping indication information, used to indicate whether there is frequency hopping transmission for the DMRS.

[0098] In one embodiment, the frequency-division multiplexing mode is used to indicate the frequency-domain multiplexing mode for transmitting one or more columns of DMRS.

[0099] In one embodiment, the frequency-domain multiplexing mode includes: type 1 or type 2; where the code-division multiplexing (CDM) group of type 1 is 2 groups, and the CDM group of type 2 is 3 groups. For example, as Figure 4 shown, in the 2nd column of symbols, 2 groups of CDM are used. Another example, as Figure 5 shown, in the 2nd and 3rd columns of symbols, 3 groups of CDM are respectively used.

[0100] In one embodiment, the transmission mode indication information includes: CDM group internal multiplexing mode information, which is used to indicate the mode of transmitting the number of multiplexing ports supported when the DMRS is for different numbers of CDM groups. For example, as Figure 4 shown, in the symbols of the second column, when the frequency-domain multiplexing mode of 2 groups of CDM is adopted for transmission, up to 4 ports can be multiplexed; for the DMRS of the 0th subcarrier, 2 ports, namely port 0 and port 1, are supported for multiplexing, etc. Also, as Figure 5 shown, in the symbols of the second column and the third column, when the frequency-domain multiplexing mode of 3 groups of CDM is adopted for transmission, up to 12 ports can be multiplexed; for the DMRS of the 0th symbol, 4 ports, namely port 0, port 1, port 6, and port 7, are supported for multiplexing, etc.

[0101] Exemplarily, when the hopping indication information is "0", it is used to indicate that there is no hopping for the DMRS; when the hopping indication information is "1", it is used to indicate that there is hopping for the DMRS.

[0102] In one embodiment, the hopping indication information is used to indicate whether there is hopping transmission of the DMRS in a time slot. In another embodiment, the hopping indication information is used to indicate whether there is hopping transmission of the DMRS between time slots.

[0103] Exemplarily, as Figure 4 shown, in the symbols of the second column of 1 time slot, there is hopping transmission. Of course, in other embodiments, the hopping indication information can also indicate whether there is hopping between time slots, or can also indicate whether there is hopping between different frequency bands, etc.

[0104] Exemplarily, the DMRS configuration information may include the type information of the DMRS. For example, when the type information of the DMRS is "0", it is used to indicate that the DMRS is not the DMRS after precoding; when the type information of the DMRS is "1", it is used to indicate that the DMRS is the DMRS after precoding.

[0105] In the embodiments of the present disclosure, the first UE may obtain first information related to the characteristic sequence of the uplink data transmitted by the second UE. For example, obtain the time-domain resource information of the time-frequency resource for transmitting the DMRS and the frequency-domain resource information of the frequency domain, the transmission mode indication information for transmitting the DMRS, and the type information of the DMRS, such as at least one or more of the number of symbols, symbol distribution information, time-domain start position, symbol position, frequency-domain multiplexing mode information, and hopping indication information. In this way, the embodiments of the present disclosure can obtain the prior information (i.e., the first information) of the characteristic sequence of the uplink data transmitted by the second UE sharing the same frequency-domain resource with the first UE; in this way, it can be beneficial for the first UE to perform relevant detections on the data transmission characteristics on the shared frequency-band resource based on this prior information.

[0106] In one embodiment, the first information includes DMRS indication information. For example, the DMRS indication information is used to indicate the characteristic information after joint coding of at least two of the number of symbols, symbol distribution information, time-domain starting position, symbol position, frequency-domain multiplexing mode information, and hopping indication information. Another example is that the DMRS indication information can also be the characteristic information after joint coding of at least two DMRS sequences among each DMRS sequence. Thus, in the embodiments of the present disclosure, each DMRS configuration information, such as the number of symbols, symbol distribution information, time-domain starting position, symbol position, frequency-division multiplexing mode, and hopping indication information, etc., is jointly coded to obtain a jointly coded characteristic information (such as a characteristic sequence, etc.); this is beneficial for the first UE to perform relevant detection on the data transmission characteristics on the shared frequency band resource based on the jointly coded characteristic information.

[0107] In the embodiments of the present disclosure, when the first UE monitors the data transmission on the shared frequency band resource of the first UE and the second UE, by detecting the correlation between the first information and the data characteristics of the second UE on the shared frequency band, it is determined whether the first UE can perform data transmission on the shared frequency band resource. Thus, the embodiments of the present disclosure can reduce the situation where the first UE determines that it can perform uplink transmission on the shared frequency band resource but loses the originally available transmission opportunity due to detecting the presence of transmitted data on the shared frequency band resource, and can greatly improve the utilization rate of the shared frequency band resource.

[0108] For example, in the Figure 2 application scenario shown, when UE1 monitors the data transmission of UE2 on the shared frequency band resource, whether it is caused by reason one or reason two. If it is caused by reason one, it can be determined that UE1 can still perform uplink transmission based on the shared frequency band resource.

[0109] In the above step S32, monitoring the transmitted data on the shared frequency band resource can be monitoring the transmitted data of any UE on the shared frequency band resource; any UE only needs to satisfy having a shared frequency band resource with the first UE.

[0110] In one embodiment, the monitoring of the data transmission on the shared frequency band resource in the above step S32 includes: monitoring the data transmission of the second UE on the shared frequency band resource.

[0111] In one embodiment, the above step S33 includes: if the data transmission on the shared frequency band resource is monitored, determine whether uplink transmission can be performed on the shared frequency band resource according to the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource. Thus, in the embodiments of the present disclosure, only when the data transmission on the shared frequency band is monitored, that is, when the shared frequency band resource is relatively busy, the correlation between the first information domain and the data transmission characteristics of the second UE on the shared frequency band resource is detected, thereby improving the detection efficiency.

[0112] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0113] As Figure 6 shown, an information processing method is provided, which is executed by a first UE and includes:

[0114] Step S61: Receive downlink control information (DCI) of the first information.

[0115] The embodiments of the present disclosure provide an information processing method, which is executed by a first UE and may include: receiving DCI sent by a network device, where the DCI carries the first information.

[0116] Exemplarily, the first UE receives DCI sent by a base station, where the DCI carries the first information. For example, the first information is carried in at least one information field of the DCI.

[0117] In some embodiments of the present disclosure, the first information may be the first information described in step S31 above.

[0118] Exemplarily, in the DCI received by the first UE, one or more of the time-domain resource information of the time-domain resource for transmitting DMRS, the frequency-domain configuration information of the frequency-domain resource for transmitting DMRS, the transmission mode indication information for transmitting DMRS, and the type information for transmitting DMRS are carried. If the first UE obtains that the second UE uses the same time-domain resource information of the time-domain resource for transmitting DMRS as the first UE, only one or more of the frequency-domain configuration information of the frequency-domain resource for transmitting DMRS, the transmission mode indication information for transmitting DMRS, and the type information for transmitting DMRS may be carried in the DCI.

[0119] In some embodiments, the above step S31 includes: receiving downlink control information DCI containing the first information.

[0120] In the embodiments of the present disclosure, the first information can be received through DCI; in this way, the first UE can accurately know the situation of the first UE's estimated uplink transmission of the second UE and can improve the utilization rate of DCI.

[0121] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0122] As Figure 7 shown, an information processing method is provided, which is executed by a first UE and includes:

[0123] Step S71: If the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than the threshold value, it is determined that uplink transmission can be performed on the shared frequency band resource; or, if the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resource.

[0124] In some embodiments of the present disclosure, the first information may be the first information described in step S31 above.

[0125] An information processing method provided by an embodiment of the present disclosure, which is executed by the first UE, may include: if the transmission beam range of the second UE covers the transmission beam range of the first UE, and the signal peak value in the time-frequency domain resource corresponding to the first information is greater than the threshold peak value, it is determined that uplink transmission can be performed on the shared frequency band resource.

[0126] An information processing method provided by an embodiment of the present disclosure, which is executed by the first UE, may include: if the transmission beam range of the second UE covers the transmission beam range of the first UE, and the signal peak value in the time-frequency domain resource corresponding to the first information is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resource.

[0127] Exemplarily, if the first information is the time-domain resource information of the time-domain resource for transmitting DMRS. For example, if the time-domain resource information indicates that DMRS is transmitted in the 2nd to 6th symbols of the 1st time slot, and if the signal peak value detected in the 2nd to 6th symbols of the 1st time slot is greater than the threshold value, it is determined that the second UE performs uplink data transmission in the 2nd to 6th symbols of the 1st time slot. At this time, since the transmission beam range of the second UE covers the transmission beam range of the first UE, it is determined that the second UE is a known interference object; and if it is determined that the UE transmitting uplink data on the shared frequency band resource is a known interference object, it is determined that the first UE can perform uplink transmission on the shared frequency band resource.

[0128] Exemplarily, if the first information is the time-domain resource information of the time-domain resource for transmitting DMRS. For example, if the time-domain resource information indicates that DMRS is transmitted in the 2nd to 6th symbols of the 1st time slot, and if the signal peak value detected in the 2nd to 6th symbols of the 1st time slot is less than or equal to the threshold value, it is determined that the second UE does not actually perform uplink data transmission in the 2nd to 6th symbols of the 1st time slot, and it is determined that there is a UE other than the second UE performing uplink data transmission in the 2nd to 6th symbols of the 1st time slot; such as Figure 2In the application scenario shown, UE1 determines that UE2 is not performing data transmission and determines that UE3 is performing uplink data transmission. At this time, the first UE determines that the interference object affecting the first UE is not the second UE, but an unknown interference object, such as a third UE that does not cover the transmission beam range of the first UE. Then, it is determined that the first UE cannot perform uplink transmission on the shared frequency band resource.

[0129] Exemplarily, if the first information is the time-domain resource information of the time-frequency resource for transmitting DMRS and the frequency-domain resource information of the frequency-domain resource for transmitting DMRS; that is, the time-domain resource information of the time-domain resource for transmitting DMRS. For example, if the time-frequency domain resource information indicates that DMRS is transmitted in the time-frequency domain resource of the 2nd to 4th symbols in the 2nd time slot and the 5th to 6th subcarriers, and if a signal peak greater than the threshold value is detected in the time-frequency domain resource of the 2nd to 4th symbols in the 2nd time slot and the 5th to 6th subcarriers, it is determined that UE2 performs uplink data transmission in the time-frequency domain resource of the 2nd to 4th symbols in the 2nd time slot and the 5th to 6th subcarriers. At this time, since the transmission beam range of the second UE covers the transmission beam range of the first UE, it is determined that the second UE is a known interference object; and it is determined that the UE transmitting uplink data on the shared frequency band resource is a known interference object, then it is determined that the first UE can perform uplink transmission on the shared frequency band resource.

[0130] Exemplarily, in the above example, if a signal peak less than or equal to the threshold value is detected in the time-frequency domain resource of the 2nd to 4th symbols in the 2nd time slot and the 5th to 6th subcarriers, it is determined that UE2 does not actually perform uplink data transmission in the time-frequency domain resource of the 2nd to 4th symbols in the 2nd time slot and the 5th to 6th subcarriers, and it is determined that other UEs except UE2 perform uplink data transmission in the time-frequency domain resource of the 2nd to 4th symbols and the 5th to 6th subcarriers in the 2nd time slot. At this time, the first UE determines that the interference object affecting the first UE is an unknown interference object, then it is determined that the first UE cannot perform uplink transmission on the shared frequency band resource.

[0131] Exemplarily, it is also possible to detect a signal peak greater than the threshold value in the time-frequency domain resources indicated by at least one of other information in the first information, such as symbol distribution information, frequency-domain multiplexing mode information, frequency hopping indication information, and CDM group-internal multiplexing mode information, etc., and determine that the first UE can perform uplink transmission on the shared frequency band resource; or, detect a signal peak less than or equal to the threshold value in the time-frequency domain resources indicated by at least one of symbol distribution information, frequency-domain multiplexing mode information, frequency hopping indication information, and CDM group-internal multiplexing mode information, etc., and determine that the first UE cannot perform uplink transmission on the shared frequency band resource.

[0132] In some embodiments, the signal peak may be, but is not limited to, the peak of the Reference Signal Receiving Power (RSRP) and / or the Reference Signal Receiving Quality (RSRQ). Of course, in other embodiments, the signal peak may be the peak of any signal characterizing data transmission on the shared frequency band.

[0133] In some embodiments, the above step S31 includes one of the following:

[0134] If the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than the threshold value, it is determined that uplink transmission can be performed on the shared frequency band resource; or,

[0135] If the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resource.

[0136] In some embodiments, if the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than the threshold value, determining whether uplink transmission can be performed on the shared frequency band resource includes:

[0137] If the transmission beam range of the second UE covers the transmission beam range of the first UE, and the signal peak in the time-frequency domain resource corresponding to the first information is greater than the threshold peak, it is determined that uplink transmission can be performed on the shared frequency band resource.

[0138] In some embodiments, if the transmission beam range of the second UE covers the transmission beam range of the first UE, and the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is less than or equal to the threshold value, determining that uplink transmission cannot be performed on the shared frequency band resource includes:

[0139] If the transmission beam range of the second UE covers the transmission beam range of the first UE, and the signal peak in the time-frequency domain resource corresponding to the first information is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resource.

[0140] In the embodiments of the present disclosure, when it is monitored that data is being transmitted on the shared frequency band, if the transmission beam range of the second UE covers the transmission beam range of the first UE, and if the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources is greater than a threshold value, it is determined that uplink transmission can be performed on the shared frequency band resources. For example, as Figure 2 shown in the application scenario, it is determined that the UE2 transmits uplink data on the shared frequency band resources; that is, it is determined that the interfering object of the UE1 is a known interfering object. Thus, the UE1 can perform uplink transmission on the shared frequency band resources.

[0141] Alternatively, when it is monitored that data is being transmitted on the shared frequency band, if the transmission beam range of the second UE covers the transmission beam range of the first UE, and if the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resources. For example, as Figure 2 shown in the application scenario, it is determined that the UE2 does not transmit uplink data on the shared frequency band resources, while the UE3 transmits uplink data on the shared frequency band resources; that is, it is determined that the interfering object of the UE1 is an unknown interfering object. Thus, the UE1 cannot perform uplink transmission on the shared frequency band resources.

[0142] Thus, in the embodiments of the present disclosure, it can be accurately determined whether the first UE can perform uplink transmission on the shared frequency band resources; when it is determined that the first UE can perform uplink transmission on the shared frequency band resources, the situation where the first UE loses the originally transmissible opportunity due to monitoring the existence of data transmission on the shared frequency band resources can be reduced, and the utilization rate of the shared frequency band resources can be greatly improved.

[0143] In other embodiments, if there is no prerequisite that the transmission beam ranges of the first UE and the second UE cover each other, that is, the transmission beam range of the second UE does not cover the transmission beam range of the first UE, then an information processing method in the embodiments of the present disclosure can also be: if the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources is greater than the threshold value, it is determined that uplink transmission can be performed on the shared frequency band resources; or, if the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources is less than or equal to the threshold value, it is determined that uplink transmission cannot be performed on the shared frequency band resources. Thus, in the embodiments of the present disclosure, it can also be directly determined whether the second UE actually performs uplink data transmission by detecting the correlation between the first information and the data transmission on the shared frequency band resources of the second UE, and further determine whether the first UE can use the shared frequency band resources for transmission.

[0144] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0145] As Figure 8 shown, an information processing method is provided, which is executed by a first UE and includes:

[0146] Step S81: If the first UE can perform uplink transmission on the shared frequency band resource, use a predetermined channel detection mechanism to detect the channel to determine whether it can occupy the shared frequency band resource.

[0147] In some embodiments of the present disclosure, the first information may be the first information described in step S31 above.

[0148] In one embodiment, the predetermined channel detection mechanism may be any mechanism for detecting a channel; for example, it may be the LBT mechanism with a higher channel occupancy priority. For example, the mechanisms for detecting a channel include but are not limited to one of the following: no LBT mechanism, no random backoff LBT mechanism, random backoff LBT with a fixed-length contention window, and random backoff LBT with a non-fixed-length contention window. In one embodiment, the above-mentioned LBT mechanism with a higher channel occupancy priority may be the mechanism that uses a relatively small contention window among the above-mentioned channel detection mechanisms.

[0149] In the present disclosure, the channel detection in the embodiments may be to detect the shared frequency band resource.

[0150] An information processing method provided by the embodiments of the present disclosure, which is executed by a first UE, may include: if the first UE can perform uplink transmission on the shared frequency band resource, use an enhanced channel access method to occupy the shared frequency band resource to perform uplink transmission.

[0151] In the embodiments of the present disclosure, if the first UE can perform uplink transmission on the shared frequency band resource, the probability of the first UE accessing the channel can be increased by detecting the channel through a predetermined channel detection mechanism, that is, the probability of the first UE occupying the shared frequency band resource to perform uplink transmission can be increased, so that the utilization rate of the shared frequency band resource for uplink transmission can be increased.

[0152] It should be noted that those skilled in the art can understand that the method provided in the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0153] As Figure 9 shown, an information processing method is provided, which is executed by a first UE and includes:

[0154] Step S91: If the first UE is unable to perform uplink transmission on the shared frequency band resource, after waiting for a predetermined time, perform the correlation detection of the data transmission characteristics of the first information and the second UE on the shared frequency band resource again.

[0155] In some embodiments of the present disclosure, the first information may be the first information described in step S31 above.

[0156] In step S71 above, after waiting for a predetermined time and then performing the correlation detection of the data transmission characteristics of the first information and the second UE on the shared frequency band resource again, it may be: detecting whether the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than a threshold value; or, it may be: if data transmission on the shared frequency band resource is monitored, detecting whether the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than a threshold value.

[0157] In one embodiment, the predetermined time may be pre-configured. In another embodiment, the predetermined time may be determined according to the time interval of the historical detection of the correlation of the output transmission characteristics of the first information and the second UE on the shared frequency band resource.

[0158] In the embodiments of the present disclosure, after the first UE determines that it is unable to perform uplink transmission on the shared frequency band resource, at this time, the first UE cannot rashly increase the LBT threshold or the like to increase the access probability of the first UE; instead, after waiting for a predetermined time, it can continue to perform the correlation detection of the data transmission characteristics of the first information and the second UE on the shared frequency band resource, so that after the subsequent correlation detection meets the conditions for the first UE to access the shared frequency band resource, the first UE can access the shared frequency band resource to perform uplink transmission.

[0159] In an information processing method provided by the embodiments of the present disclosure, which is executed by the first UE, it may include: if the first UE is unable to perform uplink transmission on the shared frequency band resource, wait for a predetermined time and then monitor the data transmission on the shared frequency band resource; if the first UE does not monitor the data transmission on the shared frequency band resource, determine that the first UE can perform uplink transmission on the shared frequency band resource. In this way, the embodiments of the present disclosure can also monitor whether the shared frequency band resource is busy after a predetermined time. If the shared frequency band resource is idle, it can also be determined that the first UE can perform uplink transmission on the shared frequency band resource.

[0160] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0161] To further explain any embodiment of the present disclosure, the following example is provided for illustration:

[0162] Combined with Figure 10 and Figure 2 as shown, an information processing method is provided. In an embodiment of the present disclosure, Figure 2 the UE1 in Figure 2 can be regarded as the first UE, and the UE2 in

[0163] Step S101: Receive the first information of the characteristic sequence of the uplink data transmitted by the second UE sent by the base station;

[0164] In one embodiment, the first UE receives the DCI sent by the base station, where the DCI carries the first information of the characteristic sequence of the uplink data transmitted by the second UE.

[0165] Step S102: Monitor the shared frequency band resources between the first UE and the second UE;

[0166] In one embodiment, the first UE monitors the shared frequency band resources between the first UE and the second UE.

[0167] Step S103: Whether data transmission on the shared frequency band resources is monitored; if yes, execute step S104; if not, execute step S107;

[0168] In one embodiment, whether the first UE monitors data transmission on the shared frequency band resources between the first UE and the second UE; if yes, execute step S104; if not, execute step S107.

[0169] Step S104: Determine whether the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources is greater than a threshold value; if yes, execute step S105; if not, execute step S106;

[0170] In one embodiment, the first UE detects the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resources, and whether this correlation is greater than a threshold value; if yes, execute step S105; if not, execute step S106.

[0171] Step S105: Determine that the first UE performs uplink transmission on the shared frequency band resources;

[0172] In one embodiment, the first UE uses an enhanced access method to perform uplink transmission using the shared frequency band resources. For example, the first UE uses a predetermined channel detection mechanism to detect the channel to determine whether it can occupy the shared frequency band resources, and after determining that it can occupy the shared frequency band resources, it occupies the shared frequency band resources to perform uplink transmission.

[0173] Step S106: Listen to the shared frequency band resource again to transmit data, so as to determine whether the shared frequency band resource can be occupied to perform uplink transmission;

[0174] In one embodiment, the first UE listens again to whether there is data transmission on the shared frequency band resource after waiting for a predetermined time. If no data transmission on the shared frequency band resource is detected, it is determined that the first UE can occupy the shared frequency band resource to perform uplink transmission; if data transmission of the second UE on the shared frequency band resource is detected, then according to the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource, it is determined whether the first UE can perform uplink transmission on the shared frequency band resource.

[0175] Step S107: Occupy the shared frequency band resource to perform uplink transmission.

[0176] In one embodiment, the first UE occupies the shared frequency band resource to perform uplink transmission.

[0177] In the embodiments of the present disclosure, the first UE can obtain the first information of the characteristic sequence of the uplink data sent by the second UE, and based on whether the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is greater than a threshold value, it is determined whether the first UE can perform uplink transmission on the shared frequency band resource; if so, it is determined that the interference of the first UE is caused by the second UE sending uplink data on the shared frequency band resource. Since the second UE is a known interference object, it is determined that the first UE can perform uplink transmission on the shared frequency band resource. In this way, the situation where the opportunity to transmit originally available is lost due to detecting that there is data transmission on the shared frequency band resource can be reduced, and the utilization rate of the shared frequency band resource can be greatly improved.

[0178] Moreover, if it is determined that the correlation between the first information and the data transmission characteristics of the second UE on the shared frequency band resource is less than or equal to the threshold value, it is determined that the second UE does not actually transmit data on the shared frequency band resource, and it is determined that the interference to the first UE is an unknown interference. In this way, the shared frequency band resource can be listened to again after waiting for a predetermined time until the shared frequency band resource is idle or the interference object that occupies the shared frequency band resource for data transmission is a known interference object, and then it is determined that the first UE can use the shared frequency band resource to perform uplink transmission; in this way, the utilization rate of the shared frequency band resource can also be improved.

[0179] It should be noted that in the embodiments of the present disclosure, when the first UE performs correlation detection, it generally can at least know whether the second UE in the same coverage interference pair as the first UE transmits data on the shared frequency band resource; for example, Figure 2 in the application scenario shown, UE1 and UE2 are in the same coverage interference pair, and UE1 at least knows whether UE2 transmits data on the shared frequency band resource to determine whether UE1 can occupy the shared frequency band resource to transmit data.
