[0026] Embodiments of the present disclosure will be described below with reference to the accompanying drawings. Elements and features described in one drawing or one embodiment of the present disclosure may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that for the purpose of clarity, representations and descriptions of components and processes that are not related to the present disclosure and are known to those of ordinary skill in the art are omitted from the drawings and descriptions.

[0027] Refer to the following Figure 1 An example configuration of an electronic device for wireless communication according to an embodiment of the present disclosure is described. Figure 1 As shown, the electronic device 100 for wireless communication according to this embodiment includes a processing circuit 110. The processing circuit 110 may be implemented as, for example, a specific chip, a chipset, or a central processing unit (CPU).

[0028] The electronic device according to this embodiment may be implemented on a user equipment (UE) side, for example.

[0029] The processing circuit 110 includes a first control unit 111 and a second control unit 113. It should be noted that although the first control unit 111 and the second control unit 113 are shown in the form of functional blocks in the figure, it should be understood that the functions of each unit can also be implemented by the processing circuit as a whole, and not necessarily by discrete actual components in the processing circuit. In addition, although the processing circuit is shown as a box in the figure, the electronic device may include multiple processing circuits, and the functions of each unit may be distributed to multiple processing circuits, so that the multiple processing circuits cooperate to perform these functions.

[0030] The first control unit 111 is configured to control to receive indication information about a bandwidth block set from a base station, where the bandwidth block set includes one or more bandwidth blocks.

[0031] The second control unit 113 is configured to control the communication with the base station by using at least one bandwidth block in the bandwidth block set.

[0032] For example, the indication information may be included in a radio resource control (RRC) signaling, and the indication information may indicate a set of configured bandwidth blocks. In this case, the UE may, for example, select a bandwidth block for uplink transmission from among the configured multiple bandwidth blocks in a grant-free manner.

[0033] Alternatively, the indication information may be included in downlink control information (DCI), and the indication information may indicate a set of activated bandwidth blocks. In this case, the base station side determines one or more activated bandwidth blocks from the configured multiple bandwidth blocks, and notifies the UE of the set of activated bandwidth blocks.

[0034] The activated bandwidth blocks are a subset of the configured bandwidth blocks, and the number of sets of activated bandwidth blocks depends on the number of configured bandwidth blocks. Accordingly, the bit width of the indication information may be determined based on the number of configured bandwidth blocks.

[0035] Before describing the indication information for the BWP set according to the embodiment of the present disclosure, as a comparative example, a method for determining the bit width of the indication information for indicating the BWP in the DCI is first described.

[0036] The bit width of the indication information for indicating the BWP may be determined as in Indicates rounding up. BWP，RRC If ≤3, n can be set BWP =n BWP，RRC +1, in which case the BWP indication is equivalent to the higher layer parameter BWP-ID. Alternatively, n BWP =n BWP，RRC , assuming that the number of configured BWPs is 4, the BWP indication can be defined as shown in Table 1 below.

[0037] Table 1

[0038] The value of the BWP indication field (2 bits) BWP 00 The first BWP configured by the top management 01 Second BWP configured by senior management 10 The third BWP configured by senior management 11 The fourth BWP configured by senior management

[0039] Different from the indication information for BWP described above, the indication information according to this embodiment indicates a set of BWPs, where each set may include one or more BWPs.

[0040] Also assuming that the number of configured BWPs is 4, the number of BWP sets is 15. Accordingly, the bit width of the indication information may be set to 4, and the BWP set indication may be defined as shown in Table 2 below, for example.

[0041] Table 2

[0042]

[0043]

[0044] It should be noted that the setting of the indication information of the BWP set is not limited to the above example, but can be set in a variety of ways. For example, the BWP set indication can also be defined in a bitmap-like manner, where each bit corresponds to a configured BWP, and when the value of a certain bit is 1, it indicates that the corresponding BWP is activated, as shown in Table 3 below.

[0045] Table 3

[0046]

[0047]

[0048] The above describes the contents related to the configuration and activation of multiple BWPs in the embodiment. Next, the contents related to transmission using multiple BWPs will be described.

[0049] According to an embodiment, the first control unit 111 may be configured to perform control to detect a pilot signal or a channel on the target bandwidth block, where the pilot signal or the channel contains information related to the future occupation duration of the target bandwidth block.

[0050] The second control unit 113 may be configured to control to notify the base station of information related to the future occupation duration. In addition to the information related to the future occupation duration, information related to the congestion level of the target bandwidth block may also be notified to the base station.

[0051] Further, the second control unit 113 may also be configured to perform control to receive downlink transmission, where the downlink transmission is sent by the base station based on the future occupation duration of the target bandwidth block.

[0052] That is, the UE can report the channel availability by detecting the pilot signal or channel, so as to help the base station select the BWP and the corresponding CCA timing, etc. By doing so, for example, when it is determined that the same or different channel access technologies (RATs) occupy a specific channel for a long time, the base station can omit unnecessary channel detection, thereby improving processing efficiency.

[0053] This process can be regarded as an enhanced preamble detection with channel occupation time indication. Incidentally, preamble detection can be performed only at BWPs that fail to perform downlink transmission due to LBT (Listen Before Transmit) failure, while energy detection can be applied to all BWPs that attempt to access.

[0054] The specific form of the channel occupancy information may vary depending on the type of preamble. For example, an enhanced new radio (NR) channel or signal may be defined, which indicates, for example, the channel occupancy duration and congestion level of the intra-RAT device occupying the channel. In addition, the type of preamble may also include, for example, an 802.11a / 802.11ax preamble, which may also indicate the channel occupancy duration and congestion level of the intra-RAT device occupying the channel.

[0055] Next, an example method of performing downlink transmission according to channel occupancy information is described in more detail.

[0056] According to one embodiment, if the occupation end time of the target bandwidth block is later than the scheduled start time of the downlink transmission by less than one time slot, the downlink transmission can be performed on the target bandwidth block through partial slot transmission. If the occupation end time of the target bandwidth block is later than the scheduled start time of the downlink transmission by more than one time slot, the downlink transmission is not performed through the target bandwidth block, that is, the use of the target bandwidth block can be abandoned.

[0057] Reference Fig. 9A and Fig. 9B An example of Fig. 9A shows an example of transmission in which the user does not provide channel occupancy information, Fig. 9B An example of transmission is shown where the user provides channel occupancy information.

[0058] like Fig. 9A As shown in the figure, when the user does not provide channel occupancy information, before uplink transmission, the UE performs LBT on each bandwidth block, wherein the LBT of part of BWP#1 and BWP#2 fails, so uplink transmission is not performed on BWP#1 and BWP#2. Similarly, before downlink transmission, the base station performs LBT on each bandwidth block, wherein the LBT of BWP#2 fails, so downlink transmission is not performed on BWP#2.

[0059] For the case where the user provides channel occupancy information, such as Fig. 9B As shown, before uplink transmission, the UE performs LBT on each bandwidth block, wherein the LBT of part of BWP#1 and BWP#2 fails, and therefore uplink transmission is not performed on BWP#1 and BWP#2. However, the UE sends channel occupancy information to the base station through BWP#0, which indicates the channel occupancy time of BWP#1, and the UE sends channel occupancy information to the base station through BWP#3, which indicates the channel occupancy time of BWP#2. Based on the channel occupancy information, the base station can determine the channel occupancy stop time of BWP#1 and BWP#2.

[0060] Since the occupation end time of BWP#1 is earlier than the scheduled start time of downlink transmission, the base station can perform downlink transmission on BWP#1 without performing LBT.

[0061] In addition, although not shown in the figure, if the occupation end time of BWP#1 is within one time slot later than the scheduled start time of downlink transmission, downlink transmission can be performed on BWP#1 through partial time slot transmission.

[0062] For BWP#2, since its occupancy end time is more than one time slot later than the scheduled start time of downlink transmission, the base station does not perform downlink transmission through BWP#2.

[0063] In addition, when information about the future occupation duration is obtained, the base station can determine whether to perform channel detection for downlink transmission on the target bandwidth block based on the interval between the occupation end time of the target bandwidth block and the planned start time of downlink transmission.

[0064] For example, if the detection result of the UE indicates that no other device is occupying the target bandwidth block, the base station may not perform channel detection but directly use the target bandwidth block to continue downlink transmission.

[0065] In addition, the base station can determine the type of channel detection to be performed based on the interval between the end time of occupation of the target bandwidth block and the planned start time of downlink transmission. As an example, there are the following LBT types: CAT1 LBT, that is, no LBT is performed; CAT2 LBT, that is, LBT is performed without random backoff; CAT3 LBT, that is, LBT is performed with a fixed backoff contention window size; CAT4 LBT, that is, LBT is performed with a variable backoff contention window size.

[0066] The following intervals may be defined: the interval between the end time of occupation of the target bandwidth block determined based on the pilot signal detected by the UE and the start time of the specified downlink transmission. For example, if the interval is less than 16 μm, downlink transmission may be performed immediately without LBT; if the interval is less than between 16 μm and 25 μm, one shot LBT may be performed; if the interval is greater than 25 μm, CAT4 LBT may be performed. It should be noted that the above examples are merely illustrative and not restrictive.

[0067] The downlink transmission described above may be performed within a shared occupation time (shared COT) of a bandwidth block set between the user equipment and the base station.

[0068] The shared occupied time may be obtained by the user equipment and shared with the base station. Fig. 9A and Fig. 9B In the example shown, the channel occupancy time is acquired by the UE and shared with the base station for downlink transmission.

[0069] In addition, the shared occupied time may also be obtained by the base station and shared with the user equipment.

[0070] See also Fig. 10A and Fig. 10B ,in Fig. 10A shows an example of transmission in which the user does not provide channel occupancy information, Fig. 10B An example of transmission is shown where the user provides channel occupancy information.

[0071] like Fig. 10AAs shown, the channel occupancy time is obtained by the base station for downlink transmission and shared with the UE for uplink transmission. In the case where the user does not provide channel occupancy information, before downlink transmission, the base station performs LBT on each bandwidth block, wherein the LBT of part of BWP#1 and BWP#2 fails, so downlink transmission is not performed on BWP#1 and BWP#2. Next, before uplink transmission, the UE performs LBT on each bandwidth block and performs uplink transmission. Then, before downlink transmission is performed again within the channel occupancy time, the base station performs LBT on each bandwidth block, wherein the LBT of part of BWP#1 and BWP#2 fails, so downlink transmission is not performed on BWP#1 and BWP#2.

[0072] For the case where the user provides channel occupancy information, such as Fig. 10B As shown, before downlink transmission, the base station performs LBT on each bandwidth block, wherein the LBT of part of BWP#1 and BWP#2 fails, and therefore downlink transmission is not performed on BWP#1 and BWP#2. Next, before uplink transmission, the UE performs LBT on each bandwidth block and performs uplink transmission. In this process, the UE sends channel occupancy information to the base station through BWP#1, which indicates the channel occupancy time of BWP#1, and the UE sends channel occupancy information to the base station through BWP#2, which indicates the channel occupancy time of BWP#2. Based on the channel occupancy information, the base station can determine the channel occupancy stop time of BWP#1 and BWP#2.

[0073] When downlink transmission is performed again within the channel occupation time, since the occupation end time of BWP#1 is within one time slot later than the planned start time of downlink transmission, downlink transmission can be performed on BWP#1 through partial time slot transmission.

[0074] For BWP#2, since its occupancy end time is more than one time slot later than the scheduled start time of downlink transmission, the base station does not perform downlink transmission through BWP#2.

[0075] It should be noted that the above examples are merely illustrative and not restrictive.

[0076] In addition, according to one embodiment, the second control unit 113 may be configured to control the information related to the future occupation duration to be transmitted through another bandwidth block other than the target bandwidth block.

[0077] The another bandwidth block includes a bandwidth block having a preset corresponding relationship with the target bandwidth block, so that the base station can determine the target bandwidth block based on the preset corresponding relationship.

[0078] For example, the preset corresponding relationship may include an adjacent relationship. Fig. 9B, the UE sends channel occupancy information to the base station through BWP#0, which indicates the channel occupancy time of BWP#1 adjacent to BWP#0, and the UE sends channel occupancy information to the base station through BWP#3, which indicates the channel occupancy time of BWP#2 adjacent to BWP#3. In addition, the indication information sent by the UE may include, for example, an indication bit to indicate the adjacent direction of the BWP. Alternatively, a corresponding relationship of rotation may be set, for example, the occupancy information of BWP#1 is indicated through BWP#0, the occupancy information of BWP#2 is indicated through BWP#1, the occupancy information of BWP#3 is indicated through BWP#2, and the occupancy information of BWP#0 is indicated through BWP#3.

[0079] It should be noted that the preset corresponding relationship is not limited to the above examples, but may include any preset corresponding relationship as long as it enables the base station to determine the target BWP according to the BWP that sends the indication information.

[0080] In addition, according to an embodiment, the second control unit 113 may also be configured to control sending a pilot signal or a channel when using the target bandwidth block for uplink transmission, the pilot signal or the channel containing information related to the future occupation duration of the target bandwidth block. Thus, other devices can determine the occupation of the target bandwidth block by the current device.

[0081] In addition, according to an embodiment, the base station may determine the future occupation duration of the target bandwidth block, and send indication information related to the future occupation duration of the target bandwidth block to the user equipment, for example, by sending indication information related to the future occupation duration to the user equipment through DCI and / or RRC signaling, so that the user equipment performs corresponding data transmission. Specifically, for example, the base station configures multiple bandwidth blocks for the user equipment by sending high-layer signaling such as RRC signaling to the user equipment, includes indication information of the activated bandwidth block in downlink control information and notifies the user equipment, and determines the future occupation duration of the activated target bandwidth block, and includes indication information of the future occupation duration in downlink control information and sends it to the user equipment, wherein the future occupation duration corresponds to a certain number of time slots.

[0082] In the above description of the apparatus according to the embodiment of the present disclosure, it is obvious that some methods and processes are also disclosed. Next, without repeating the details described above, a description of the wireless communication method according to the embodiment of the present disclosure is given.

[0083] like Figure 2 As shown, the wireless communication method according to this embodiment includes step S210 of receiving indication information about a bandwidth block set from a base station, wherein the bandwidth block set includes one or more bandwidth blocks.

[0084] In addition, the method further includes step S220 of communicating with a base station by using at least one bandwidth block in the bandwidth block set.

[0085] The above describes an embodiment that can be implemented on the user equipment side. In addition, the embodiments of the present disclosure also include an apparatus and method that can be implemented on the base station side. Next, without repeating the details corresponding to the details described above, a description of an embodiment of the apparatus and method corresponding to the base station side according to the embodiments of the present disclosure is given.

[0086] Also refer to Figure 1 According to the present embodiment, the electronic device 100 for wireless communication includes a processing circuit 110. The processing circuit 110 includes a first control unit 111 and a second control unit 113.

[0087] The first control unit 111 is configured to control to send indication information about a bandwidth block set to the user equipment, where the bandwidth block set includes one or more bandwidth blocks.

[0088] The second control unit 113 is configured to control the communication with the user equipment by using at least one bandwidth block in the bandwidth block set.

[0089] According to one embodiment, the second control unit 113 may also be configured to control receiving information related to the future occupation duration of the target bandwidth block from the user equipment. The information related to the future occupation duration may be obtained by the user equipment by detecting a pilot signal or channel on the target bandwidth block.

[0090] According to an embodiment, the second control unit 113 may also be configured to control sending downlink transmission to the user equipment based on the future occupation duration of the target bandwidth block.

[0091] The downlink transmission may be performed during the shared occupation time of the bandwidth block set between the user equipment and the base station. The shared occupation time may be obtained by the user equipment or by the base station.

[0092] If the occupation end time of the target bandwidth block is within one time slot later than the scheduled start time of the downlink transmission, the downlink transmission can be performed on the target bandwidth block through partial time slot transmission. If the occupation end time of the target bandwidth block is more than one time slot later than the scheduled start time of the downlink transmission, the downlink transmission is not performed through the target bandwidth block.

[0093] According to one embodiment, the second control unit 113 may also be configured to determine whether to perform channel detection for downlink transmission on the target bandwidth block based on the interval between the occupancy end time of the target bandwidth block and the planned start time of the downlink transmission, and / or determine the type of channel detection.

[0094] According to one embodiment, the second control unit 113 may also be configured to control to receive information related to the future occupation duration through another bandwidth block other than the target bandwidth block. The other bandwidth block may include a bandwidth block having a preset corresponding relationship with the target bandwidth block, so that the target bandwidth block can be determined based on the predetermined corresponding relationship.

[0095] Figure 3 An example of a process of a corresponding wireless communication method is shown. Figure 3 As shown, at S310, indication information about a bandwidth block set is sent to a user equipment, where the bandwidth block set includes one or more bandwidth blocks. At S320, at least one bandwidth block in the bandwidth block set is used to communicate with the user equipment.

[0096] The above describes the embodiments of aspects related to configuration and activation of multiple BWPs, although aspects related to transmission using multiple BWPs are involved therein, however, the embodiments of these two aspects can be implemented independently of each other.

[0097] Next, the embodiments of the apparatus and method of another aspect of the present disclosure are described, including apparatus and method corresponding to the user equipment side and apparatus and method corresponding to the base station side. Since part of the content of this aspect has been described in conjunction with the embodiments of the first aspect, the repeated description of some details will be omitted below.

[0098] Also refer to Figure 1 According to the present embodiment, the electronic device 100 for wireless communication includes a processing circuit 110. The processing circuit 110 includes a first control unit 111 and a second control unit 113.

[0099] The first control unit 111 is configured to perform control to detect a pilot signal or a channel on the target bandwidth block, where the pilot signal or the channel contains information related to a future occupation duration of the target bandwidth block.

[0100] The second control unit 113 is configured to control so as to notify the base station of information related to the future occupation duration. In addition, information related to the congestion level of the target bandwidth block may also be notified to the base station.

[0101] According to an embodiment, the second control unit 113 may also be configured to perform control to receive downlink transmission, where the downlink transmission is sent by the base station based on the future occupation duration of the target bandwidth block.

[0102] The downlink transmission may be performed during the shared occupation time of the configured bandwidth block set between the user equipment and the base station. The shared occupation time may be obtained by the user equipment or by the base station.

[0103] If the occupation end time of the target bandwidth block is within one time slot later than the planned start time of the downlink transmission, the downlink transmission can be performed on the target bandwidth block through partial time slot transmission. If the occupation end time of the target bandwidth block is more than one time slot later than the planned start time of the downlink transmission, the downlink transmission is not performed through the target bandwidth block.

[0104] In addition, the base station may also determine whether to perform channel detection for downlink transmission on the target bandwidth block based on the interval between the occupation end time of the target bandwidth block and the planned start time of downlink transmission, and / or may determine the type of channel detection.

[0105] According to an embodiment, the second control unit 113 may be further configured to control the information related to the future occupation duration to be sent through another bandwidth block other than the target bandwidth block.

[0106] The another bandwidth block may include a bandwidth block having a preset corresponding relationship with the target bandwidth block, so that the base station can determine the target bandwidth block based on the predetermined corresponding relationship.

[0107] According to an embodiment, the second control unit 113 may also be configured to control the sending of a pilot signal or a channel, where the pilot signal or the channel contains information related to the future occupation duration of the used bandwidth block.

[0109] The indication information may be included in radio resource control signaling and indicate a set of configured bandwidth blocks. Alternatively, the indication information may be included in a downlink control indication and indicate a set of activated bandwidth blocks.

[0110] The bit width of the indication information may be based on the number of configured bandwidth blocks.

[0111] Figure 4 An example of a process of a corresponding wireless communication method is shown. Figure 4 As shown, the method includes step S410 of detecting a pilot signal or channel on a target bandwidth block. The pilot signal or channel includes information related to the future occupation duration of the target bandwidth block. The method also includes step S420 of notifying the base station of the information related to the future occupation duration.

[0112] Refer again Figure 1 An embodiment of the present aspect implemented on the base station side is described.

[0113] The electronic device 100 for wireless communication according to the present embodiment includes a processing circuit 110. The processing circuit 110 includes a first control unit 111 and a second control unit 113.

[0114] The first control unit 111 is configured to control to receive information related to the future occupation duration of the target bandwidth block from the user equipment. The information related to the future occupation duration may be obtained by the user equipment by detecting a pilot signal or a channel on the target bandwidth block.

[0115] The second control unit 113 is configured to control sending downlink transmission to the user equipment based on the future occupation duration.

[0116] The downlink transmission may be performed during the shared occupation time of the bandwidth block set between the user equipment and the base station. The shared occupation time may be obtained by the user equipment or by the base station.
