[0002] Currently, the R17 version introduces directional listen-before-speak (directional LBT) in its research on frequency bands above 52.6 GHz.

[0003] If multiple beams are transmitted in different directions within a Channel Occupation Time (COT), then the corresponding LBT (Low-Level Transmission) needs to be performed on each beam before the COT begins.

[0004] However, there is no solution for determining the backoff counter value for each beam when performing LBT. Summary of the Invention

[0011] Optionally, selecting a random positive integer between [0, CWp] includes: selecting the random positive integer in [0, CWp] with a uniform probability distribution.

[0012] To address the aforementioned technical problems, this invention also provides a multi-beam transmission device, comprising: a priority determination unit, configured to determine the reference channel access priority corresponding to all beams within an occupied time; and a backoff count value determination unit, configured to determine the backoff count value corresponding to all beams based on the contention window parameter, wherein the backoff count values ​​corresponding to all beams are the same.

[0013] Optionally, the priority determination unit is used to obtain the minimum channel access priority corresponding to the physical shared channel associated with each beam, wherein the physical shared channel includes a physical uplink shared channel and / or a physical downlink shared channel; and to use the minimum value among the minimum channel access priorities corresponding to all beams as the reference channel access priority.

[0015] Optionally, the priority determination unit is used to take the channel access priority of any physical uplink shared channel corresponding to any beam as the reference channel access priority; or, take the channel access priority of any physical downlink shared channel corresponding to any beam as the reference channel access priority.

[0017] Optionally, the backoff count value determination unit is used to select the random positive integer in [0, CWp] with a uniform probability distribution.

[0018] This invention also provides a computer-readable storage medium, which is a non-volatile or non-transient storage medium, storing a computer program thereon. When the computer program is run by a processor, it executes the steps of any of the above-described multi-beam transmission methods.

When the processor runs the computer program, it executes the steps of any of the multi-beam transmission methods described above.

[0020] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects:

[0021] The reference channel access priority for all beams within the occupied time is determined, and then the contention window parameters corresponding to the reference channel access priorities are obtained. Based on the contention window parameters, the backoff count value for each beam is determined; all beams have the same backoff count value. Therefore, the backoff count value for each beam within the occupied time can be determined. Furthermore, since the backoff count value for all beams within the occupied time is the same, different beams can perform LBT in different directions at the same time. Attached Figure Description

[0023] Figure 2 This is a schematic diagram of the structure of a multi-beam transmission device according to an embodiment of the present invention. Detailed Implementation

[0024] As described in the background section above, there is no solution in the prior art for determining the backoff counter value for each beam during LBT.

[0025] In this embodiment of the invention, the reference channel access priority corresponding to all beams within the occupied time is determined, and then the contention window parameter corresponding to the reference channel access priority is obtained. The backoff count value corresponding to all beams is determined based on the contention window parameter or the LBT access priority class, and all beams have the same backoff count value. Therefore, the backoff count value corresponding to all beams within the occupied time can be determined. Furthermore, since the backoff count value corresponding to all beams within the occupied time is the same, different beams can perform LBT in different directions at the same time.

[0026] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] This invention provides a multi-beam transmission method, referring to... Figure 1 The following will provide a detailed explanation through specific steps.

[0028] In specific implementation, the multi-beam transmission method provided in steps S101 to S103 below can be executed by a chip with data processing function (such as a baseband chip) in the user equipment, or by a chip module in the user equipment that contains a chip with data processing function.

[0029] Step S101: Determine the access priority of the reference channel corresponding to all beams within the occupied time.

[0030] In practice, multiple beams can exist within a single Channel Occupation Time (COT), and these beams can correspond to different beams. Before the start of the COT, all beams within that COT need to undergo Listen Before Talk (LBT).

[0031] In this embodiment of the invention, the channel access priority corresponding to the physical shared channel associated with each beam can be obtained during the occupied time. The physical shared channel includes the Physical Uplink Shared Channel (PUSCH) and / or the Physical Downlink Shared Channel (PDSCH).

[0032] In practical applications, the channel access priority corresponding to the PUSCH or the channel access priority corresponding to the PDSCH can be obtained from the downlink control information (DCI) of the PDSCH or PUSCH.

[0033] In this embodiment of the invention, it is necessary to determine a reference channel access priority, which can be used for the LBT (Local Time Bypass) of the occupancy time. All LBT directions corresponding to the occupancy time can use the same channel access priority. Alternatively, all LBT directions corresponding to the occupancy time can have the same backoff counter.

[0034] In this embodiment of the invention, if a beam is associated with multiple PUSCHs, the channel access priority corresponding to each PUSCH can be obtained separately, and then the lowest channel access priority can be selected. If a beam is associated with only one PUSCH, the channel access priority corresponding to that PUSCH is taken as the lowest channel access priority corresponding to that beam. The lowest channel access priority refers to the access channel priority with the smallest index number.

[0035] Accordingly, if a beam is associated with only one PDSCH, the channel access priority corresponding to each PDSCH can be obtained, and then the lowest channel access priority can be selected. If a beam is associated with only one PDSCH, the channel access priority corresponding to that PDSCH is taken as the lowest channel access priority for that beam.

[0036] For example, beam 1 is associated with PUSCH including PUSCH1 and PUSCH2. The channel access priority corresponding to PUSCH1 is 1, and the channel access priority corresponding to PUSCH2 is 2. Then the minimum channel access priority selected is 1.

[0037] For example, the PDSCH associated with beam 2 includes PDSCH1 and PDSCH2. The channel access priority corresponding to PDSCH1 is 1, and the channel access priority corresponding to PDSCH2 is 2. Therefore, the minimum channel access priority selected is 1.

[0038] After obtaining the minimum channel access priority corresponding to the physical shared channel associated with each beam, the minimum value among the minimum channel access priorities corresponding to all beams is used as the reference channel access priority.

[0039] For example, a time slot may include four beams, namely beam 1, beam 2, beam 3, and beam 4. The minimum channel access priority for beam 1 is 1, for beam 2 it is 2, for beam 3 it is 2, and for beam 4 it is 3. Therefore, the final reference channel access priority is determined to be 1.

[0040] In this embodiment of the invention, if a beam is associated with multiple PUSCHs, the channel access priority corresponding to each PUSCH can be obtained separately, and then the highest channel access priority can be selected. If a beam is associated with only one PUSCH, the channel access priority corresponding to that PUSCH is taken as the highest channel access priority corresponding to that beam. Here, the highest channel access priority refers to the access channel priority with the highest index number.

[0041] Accordingly, if a beam is associated with multiple PDSCHs, the channel access priority corresponding to each PDSCH can be obtained separately, and then the highest channel access priority can be selected. If a beam is associated with only one PDSCH, the channel access priority corresponding to that PDSCH is taken as the highest channel access priority for that beam.

[0042] For example, beam 1 is associated with PUSCH including PUSCH1 and PUSCH2. PUSCH1 has a channel access priority of 1 and PUSCH2 has a channel access priority of 2. Then the maximum channel access priority selected is 2.

[0043] For example, if beam 2 is associated with PDSCH including PDSCH1 and PDSCH2, and the channel access priority corresponding to PDSCH1 is 1 and the channel access priority corresponding to PDSCH2 is 2, then the maximum channel access priority selected is 2.

[0044] After obtaining the maximum channel access priority corresponding to the physical shared channel associated with each beam, the maximum value among the maximum channel access priorities corresponding to all beams is used as the reference channel access priority.

[0045] For example, a time slot may include four beams, namely beam 1, beam 2, beam 3, and beam 4. The maximum channel access priority corresponding to beam 1 is 1, the maximum channel access priority corresponding to beam 2 is 2, the maximum channel access priority corresponding to beam 3 is 2, and the maximum channel access priority corresponding to beam 4 is 3. Therefore, the final reference channel access priority is determined to be 3.

[0046] In this embodiment of the invention, if there is only one PUSCH associated with a beam, the channel access priority corresponding to that PUSCH can be obtained and used as a reference channel access priority. Conversely, if there are multiple PDSCHs associated with a beam, the channel access priority corresponding to each PDSCH can be obtained separately, and then the highest channel access priority can be selected.

[0047] For example, beam 1 is associated with PUSCH including PUSCH1 and PUSCH2. PUSCH1 has a channel access priority of 1 and PUSCH2 has a channel access priority of 2. Then the maximum channel access priority selected is 2.

[0048] For example, if beam 2 is associated with PDSCH including PDSCH1 and PDSCH2, and the channel access priority corresponding to PDSCH1 is 1 and the channel access priority corresponding to PDSCH2 is 2, then the maximum channel access priority selected is 2.

[0049] After obtaining the maximum channel access priority corresponding to the physical shared channel associated with each beam, the maximum value among the maximum channel access priorities corresponding to all beams is used as the reference channel access priority.

[0050] For example, a time slot may include four beams, namely beam 1, beam 2, beam 3, and beam 4. The maximum channel access priority corresponding to beam 1 is 1, the maximum channel access priority corresponding to beam 2 is 2, the maximum channel access priority corresponding to beam 3 is 2, and the maximum channel access priority corresponding to beam 4 is 3. Therefore, the final reference channel access priority is determined to be 3.

[0051] In this embodiment of the invention, if each beam is associated with only one PUSCH or one PDSCH during the occupied time, the minimum value among the channel access priorities corresponding to all beam-associated PUSCHs or PDSCHs is selected as the reference channel access priority; or, the maximum value among the channel access priorities corresponding to all beam-associated PUSCHs or PDSCHs is selected as the reference channel access priority.

[0052] For example, a single occupied time period includes four beams, namely beam 1, beam 2, beam 3, and beam 4. Beam 1 is associated with PUSCH1, and the channel access priority corresponding to PUSCH1 is 1; beam 2 is associated with PUSCH2, and the channel access priority corresponding to PUSCH2 is 2; beam 3 is associated with PUSCH3, and the channel access priority corresponding to PUSCH3 is 2; beam 4 is associated with PDSCH1, and the channel access priority corresponding to PDSCH1 is 3.

[0053] If the maximum value among the channel access priorities is selected as the reference channel access priority, then the reference channel access priority is 3; if the minimum value among the channel access priorities is selected as the reference channel access priority, then the reference channel access priority is 1.

[0054] In this embodiment of the invention, the channel access priority of any PUSCH corresponding to any beam within the occupied time period can also be used as the reference channel access priority; or, the channel access priority of any PDSCH corresponding to any beam within the occupied time period can be used as the reference channel access priority.

[0055] For example, a single occupied time period includes four beams, namely beam 1, beam 2, beam 3, and beam 4. Beam 1 is associated with PUSCH1, and the channel access priority corresponding to PUSCH1 is 1; beam 2 is associated with PUSCH2, and the channel access priority corresponding to PUSCH2 is 2; beam 3 is associated with PUSCH3, and the channel access priority corresponding to PUSCH3 is 2; beam 4 is associated with PDSCH1, and the channel access priority corresponding to PDSCH1 is 3. If the channel access priority corresponding to PUSCH2 is selected as the reference channel access priority, then the reference channel access priority is determined to be 2.

[0056] In this embodiment of the invention, any channel access priority can also be confirmed as a reference channel access priority. That is, the reference channel access priority is different from the channel access priority corresponding to any beam within the occupied time.

[0057] In this embodiment of the invention, all beams within the same occupied time period have the same reference channel access priority.

[0058] Step S102: Obtain the contention window parameters corresponding to the access priority of the reference channel.

[0059] In practice, after obtaining the reference channel access priority, the corresponding contention window parameters can be determined based on the reference channel access priority in the preset mapping relationship between channel access priority and contention window parameters.

[0060] According to existing protocols, when the channel access priority is 1, the maximum value of the corresponding contention window is CW. max,p The value is 7, and the minimum value is CW. min,p The contention window parameter CWp is 3 or 7; when the channel access priority is 2, the maximum value of the corresponding contention window CWp is 3. max,p The minimum value is 15, CW. min,p The contention window parameter CWp is 7 or 15; when the channel access priority is 3, the maximum value of the corresponding contention window CWp is 7. max,p The value is 63, and the minimum value is CW. min,p The contention window parameter CWp is 15, and its value can be any value from the set {15, 31, 63}; when the channel access priority is 4, the maximum value of the corresponding contention window is CW. max,p The minimum value is 1023, CW. min,pThe value is 15, and the competition window parameter CWp can take any value from the set {15, 31, 63, 127, 255, 511, 1023}.

[0061] Therefore, if the reference channel access priority is determined to be 1, and the contention window parameter is determined to be 3 or 7 according to the existing protocol.

[0062] Step S103: Determine the backoff count value corresponding to all beams based on the competition window parameters.

[0063] In practice, after obtaining the contention window parameter CWp, the backoff count value corresponding to all beams within the occupied time can be determined based on the obtained contention window parameter.

[0064] In this embodiment of the invention, the backoff count values ​​corresponding to all beams within a given time period are equal. That is, within a given time period, beams from different directions correspond to the same backoff count value.

[0065] In practice, a positive integer can be selected from the interval [0, CWp] and used as the backoff counter value for all beams.

[0066] In this embodiment of the invention, a random positive integer can be selected in the interval [0, CWp], and the selected random positive integer can be used as the backoff counter value for all beams.

[0067] For example, if the competition window parameter CWp is obtained to be 7, and a positive integer of 3 is randomly selected from 0 to 7, then 3 will be used as the backoff count value for all beams.

[0068] In this embodiment of the invention, a random positive integer can be selected in the interval [0, CWp] with a uniform probability as the backoff count value corresponding to all beams.

[0069] For example, if the competition window parameter CWp is set to 7, then every positive integer between 0 and 7 has an equal probability of being selected. If the randomly selected positive integer is 2, then 2 will be used as the backoff count value for all beams.

[0070] In this embodiment of the invention, a positive integer corresponding to the value of CWp can be selected from the interval [0, CWp] as the backoff count value for all beams, based on the value of CWp.

[0071] For example, when CWp is 7, the fixed positive integer selected is 4; when CWp is 15, the fixed positive integer selected is 8.

[0072] In this embodiment of the invention, a fixed positive integer can be selected for all CWp values ​​as the backoff count value for all beams. That is, regardless of the value of CWp, the final selected backoff count value for all beams is the same.

[0073] For example, the fixed positive integer corresponding to all values ​​of CWp is 4.

[0074] The multi-beam transmission method provided in the above embodiments of the present invention will be described below through specific examples.

[0075] Example 1

[0076] A time period is defined with N beams, each beam associated with multiple PDSCH transmissions or multiple PUSCH transmissions. The downlink control information (DCI) scheduling the PDSCHs or PUSCHs carries the channel access priority for each PDSCH or PUSCH.

[0077] Typically, a beam is associated with multiple PDSCHs, or a beam is associated with multiple PUSCHs. When a beam is associated with multiple PDSCHs, the lowest channel access priority is selected from the channel access priorities corresponding to the multiple PDSCHs, and this lowest channel access priority is used as the minimum channel access priority for that beam. Similarly, when a beam is associated with multiple PUSCHs, the lowest channel access priority is selected from the channel access priorities corresponding to the multiple PUSCHs, and this lowest channel access priority is used as the minimum channel access priority for that beam.

[0078] For example, if beam 1 is associated with PDSCH1 and PDSCH2, and the channel access priority corresponding to PDSCH1 is 2 and the channel access priority corresponding to PDSCH2 is 3, then the minimum channel access priority corresponding to beam 1 is 2.

[0079] By analogy, the minimum channel access priority corresponding to all beams within the occupied time period is obtained.

[0080] After obtaining the minimum channel access priority for all beams within the occupied time, the minimum value is selected from the minimum channel access priorities for all beams and used as the reference channel access priority.

[0081] For example, if there are 4 beams within a certain time period, namely beam 1, beam 2, beam 3 and beam 4, and the minimum channel access priority corresponding to beam 1 is 2, the minimum channel access priority corresponding to beam 2 is 3, the minimum channel access priority corresponding to beam 3 is 2, and the minimum channel access priority corresponding to beam 4 is 1, then the reference channel access priority is determined to be 1.

[0082] From the preset mapping relationship between channel access priority and contention window parameters, it can be seen that when the channel access priority is 1, the corresponding maximum value of the contention window is CW. max,p The value is 7, and the minimum value is CW. min,p Since the value is 3, the contention window parameter CWp can be either 3 or 7. According to the existing protocol, the contention window parameter CWp is determined to be 3. Randomly selecting a positive integer 2 from 0 to 3 ensures that the backoff count values ​​for beams 1 through 4 are all 2.

[0083] Example 2

[0084] A time period is defined with N beams, each beam associated with multiple PDSCH transmissions or multiple PUSCH transmissions. The DCI (Distributed Channel Access Control) that schedules PDSCHs or PUSCHs carries the channel access priority for each PDSCH or PUSCH.

[0085] If a beam is associated with multiple PDSCHs, the highest channel access priority among the multiple PDSCHs is selected as the maximum channel access priority for that beam. Similarly, if a beam is associated with multiple PUSCHs, the highest channel access priority among the multiple PUSCHs is selected as the maximum channel access priority for that beam.

[0086] For example, if beam 1 is associated with PDSCH1 and PDSCH2, and the channel access priority corresponding to PDSCH1 is 2 and the channel access priority corresponding to PDSCH2 is 3, then the maximum channel access priority corresponding to beam 2 is 3.

[0087] By analogy, the maximum channel access priority corresponding to all beams within the occupied time period can be obtained.

[0088] After obtaining the maximum channel access priority for all beams within the occupied time, the maximum value is selected from the maximum channel access priorities for all beams as the reference channel access priority.

[0089] For example, if there are 4 beams within a certain time period, namely beam 1, beam 2, beam 3 and beam 4, and the maximum channel access priority corresponding to beam 1 is 2, the maximum channel access priority corresponding to beam 2 is 3, the maximum channel access priority corresponding to beam 3 is 2, and the maximum channel access priority corresponding to beam 4 is 1, then the reference channel access priority is determined to be 3.

[0090] From the preset mapping relationship between channel access priority and contention window parameters, it can be seen that when the channel access priority is 1, the corresponding maximum value of the contention window is CW. max,pIt is 63, and the maximum value is CW. min,p The contention window parameter CWp is set to 15, and can take values ​​of 15, 31, or 63. According to the existing protocol, the contention window parameter CWp is set to 15. A positive integer of 4 is randomly selected from 0 to 15, thus determining that the backoff count value for beams 1 through 4 is all 4.

[0091] Example 3

[0092] Within a specified time period, N beams are defined, each beam associated with either a PDSCH transmission or a PUSCH transmission. The DCI (Distributed Channel Access Control) that schedules the PDSCH or PUSCH carries the channel access priority corresponding to each PDSCH or PUSCH.

[0093] The channel access priority corresponding to a PDSCH associated with each beam is taken as the channel access priority corresponding to that beam, or the channel access priority corresponding to a PUSCH associated with each beam is taken as the channel access priority corresponding to that beam.

[0094] Select the minimum value from the channel access priorities corresponding to N beams as the reference channel access priority.

[0095] For example, if there are 4 beams within a certain time period, namely beam 1, beam 2, beam 3 and beam 4, the channel access priority corresponding to beam 1 is 2, the channel access priority corresponding to beam 2 is 3, the channel access priority corresponding to beam 3 is 2, and the channel access priority corresponding to beam 4 is 1, then the reference channel access priority is determined to be 1.

[0096] From the preset mapping relationship between channel access priority and contention window parameters, it can be seen that when the channel access priority is 1, the corresponding maximum value of the contention window is CW. max,p The value is 7, and the minimum value is CW. min,p Since the value is 3, the contention window parameter CWp can be either 3 or 7. According to the existing protocol, the contention window parameter CWp is determined to be 3. Randomly selecting a positive integer 2 from 0 to 3 ensures that the backoff count values ​​for beams 1 through 4 are all 2.

[0097] Example 4

[0098] Within a specified time period, N beams are defined, each beam associated with either a PDSCH transmission or a PUSCH transmission. The DCI (Distributed Channel Access Control) that schedules the PDSCH or PUSCH carries the channel access priority corresponding to each PDSCH or PUSCH.

[0099] The channel access priority corresponding to a PDSCH associated with each beam is taken as the channel access priority corresponding to that beam, or the channel access priority corresponding to a PUSCH associated with each beam is taken as the channel access priority corresponding to that beam.

[0100] Select the maximum value from the channel access priorities corresponding to N beams as the reference channel access priority.

[0101] For example, if there are 4 beams within a certain time period, namely beam 1, beam 2, beam 3 and beam 4, and the channel access priority corresponding to beam 1 is 2, the channel access priority corresponding to beam 2 is 3, the channel access priority corresponding to beam 3 is 2, and the channel access priority corresponding to beam 4 is 1, then the reference channel access priority is determined to be 3.

[0102] From the preset mapping relationship between channel access priority and contention window parameters, it can be seen that when the channel access priority is 1, the corresponding maximum value of the contention window is CW. max,p It is 63, and the maximum value is CW. min,p The contention window parameter CWp is set to 15, and can take values ​​of 15, 31, or 63. According to the existing protocol, the contention window parameter CWp is set to 15. A positive integer of 4 is randomly selected from 0 to 15, thus determining that the backoff count value for beams 1 through 4 is all 4.

[0103] Therefore, in this embodiment of the invention, the reference channel access priority corresponding to all beams within the occupied time is determined, and then the contention window parameters corresponding to the reference channel access priorities are obtained. The backoff count value corresponding to all beams is determined based on the contention window parameters, and the backoff count values ​​corresponding to all beams are the same. Thus, the backoff count value corresponding to all beams within the occupied time can be determined. Furthermore, since the backoff count value corresponding to all beams is the same within the occupied time, different beams can perform LBT in different directions at the same time.

[0104] Reference Figure 2 A schematic diagram of a multi-beam transmission device according to an embodiment of the present invention is provided. The multi-beam transmission device 20 includes: a priority determination unit 201, an acquisition unit 202, and a backoff count value determination unit 203, wherein:

[0107] The backoff count determination unit 203 is used to determine the backoff count value corresponding to all beams according to the competition window parameters, wherein the backoff count value corresponding to all beams is the same.

[0110] In a specific implementation, the priority determination unit 201 can be used to take the channel access priority of any physical uplink shared channel corresponding to any beam as the reference channel access priority; or, take the channel access priority of any physical downlink shared channel corresponding to any beam as the reference channel access priority.

[0111] In a specific implementation, the backoff count value determination unit 203 can be used to select a random positive integer in [0, CWp] and use the random positive integer as the backoff count value corresponding to all beams, where CWp is the competition window parameter.

[0112] In a specific implementation, the retreat count value determination unit 203 can be used to select the random positive integer in [0, CWp] with a uniform probability distribution.

[0113] In specific implementation, the aforementioned multi-beam transmission device 20 may correspond to a chip with data processing function in the user equipment, such as a baseband chip; or to a chip in the user equipment that includes a baseband chip; or to the user equipment itself.
