[0103] An embodiment of the present disclosure provides a method for determining a detection beam for an unlicensed uplink channel, which is applied to the user equipment 101. The method includes steps S110d to S120d.

[0104] In step S110d, first beam setting information is received from the network device, where the first beam setting information indicates a transmission beam for transmitting the unlicensed uplink channel.

[0105] In step S120d, a detection beam for performing LBT detection on the unlicensed uplink channel is determined based on the transmission beam indicated by the first beam setting information and the first selection condition promised by the protocol.

[0106] Optionally, the method further includes step S130d, in which, in step S130d, in response to determining a detection beam for performing LBT detection on the unlicensed uplink channel, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0107] In some possible embodiments, the first selection condition is at least: the detection beam is the transmit beam; The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship; or The detection beam is a detection beam associated with the transmission beam.

[0108] Three examples are given below.

[0109] In Example 1, The first selection condition is condition 1, i.e., "the detection beam is the transmission beam," and the user equipment determines that beam A is the transmission beam based on the first beam setting information. Based on condition 1, the user equipment directly determines beam A as the detection beam, and can then perform LBT detection using beam A.

[0110] In Example 2, The first selection condition is condition 2, i.e., "the coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship." The set relationship is that the 3 dB beamwidth of the transmission beam is within the 3 dB beamwidth of the detection beam. Based on the first beam setting information, the user equipment determines that the transmission beams of the unlicensed uplink channel include beam A, beam B, and beam C, and based on condition 2, determines that the beam that satisfies the set relationship is beam A. Beam A is determined to be the detection beam, and then beam A is used to perform LBT detection.

[0111] In Example 3, The first selection condition is condition 3, i.e., "the detection beam is a detection beam associated with the transmission beam," where the base station associates three beams, i.e., beam E, beam F, and beam G, with the transmission beam of the unlicensed uplink channel. The user equipment determines the transmission beam of the unlicensed uplink channel and condition 3 based on the first beam setting information, and determines that the beams that satisfy the set relationship are beam E, beam F, and beam G.

[0112] In an embodiment of the present disclosure, a first selection condition can be promised in the protocol, and after the user equipment determines a transmission beam for the unlicensed uplink channel, it can determine a detection beam for this unlicensed uplink channel based on the first selection condition, and perform LBT detection for this unlicensed uplink channel on this detection beam.

[0113] An embodiment of the present disclosure provides a method for determining a detection beam for an unlicensed uplink channel, which is applied to the user equipment 101. The method includes steps S110e to S120e.

[0114] In step S110e, first beam setting information is received from the network device, where the first beam setting information indicates a transmission beam for transmitting the unlicensed uplink channel.

[0115] In step S120e, a detection beam for performing LBT detection on the unlicensed uplink channel is determined based on the transmission beam indicated by the first beam setting information and the second selection condition promised by the protocol.

[0116] Optionally, the method may further include step S130e, in which, in step S130e, in response to determining a detection beam for performing LBT detection on the unlicensed uplink channel, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0117] In some possible embodiments, the second selection condition is at least: The beam width is the largest at the set attenuation. or Including the smallest spatial relationship information index.

[0118] Two examples are given below.

[0119] In Example 1, The first selection condition is condition 4, i.e., "the beam width at the set attenuation is the largest," and the user equipment determines that beam A and beam B are the transmission beams based on the first beam setting information. If the user equipment determines based on condition 4 that, of beam A and beam B, beam A is the beam with the largest beam width at the set attenuation, it determines beam A as the detection beam and can then perform LBT detection using beam A.

[0120] In Example 2, The first selection condition is condition 5, i.e., "the spatial relationship information index is the smallest," and based on the first beam setting information of the user equipment, the user equipment determines that beam A and beam B are the transmission beams. If the user equipment determines based on condition 5 that beam B is the beam with the smallest spatial relationship information index among beam A and beam B, the user equipment determines beam B as the detection beam, and can then perform LBT detection using beam B.

[0121] In an embodiment of the present disclosure, the protocol may stipulate a second selection condition, and after determining a transmission beam for an unlicensed uplink channel, the user equipment may determine a detection beam for the unlicensed uplink channel based on the second selection condition, and then perform LBT detection on the unlicensed uplink channel using the detection beam. Of course, in the above example, the second selection condition is based on the selection result of the first selection condition, but the second selection condition may not be dependent on the first selection condition. In other words, multiple detection beams may be determined as a set of detection beam candidates using other methods, and one detection beam may be selected from the set based on the second selection condition.

[0122] An embodiment of the present disclosure provides a method for determining a detection beam for an unlicensed uplink channel, which is applied to the user equipment 101. The method includes steps S110c to S130c.

[0123] In step S110c, first beam setting information is received from the network device, where the first beam setting information indicates a transmission beam for transmitting the unlicensed uplink channel.

[0124] In step S120c, a detection beam for performing LBT detection on the unlicensed uplink channel is determined based on the transmission beam indicated by the first beam setting information and the first selection condition and second selection condition promised by the protocol.

[0125] In step S130c, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0126] In some possible embodiments, The first selection condition is at least: the detection beam is the transmit beam; The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship; or The detection beam is a detection beam associated with the transmission beam.

[0127] In some possible embodiments, the second selection condition is at least: The beam width is the largest at the set attenuation. or Including the smallest spatial relationship information index.

[0128] An example will be described below.

[0129] for example, The first selection condition is condition 3, i.e., "the detection beam is the detection beam associated with the transmission beam," and the second selection condition is condition 5, i.e., "the beam width is the largest at the set attenuation."

[0130] Based on the first beam setting information, the user equipment determines that beam A and beam B are the transmission beams. If the user equipment determines that beam A is the beam that simultaneously satisfies conditions 4 and 5 between beam A and beam B, it determines beam A as the detection beam and then performs LBT detection using beam A.

[0131] In an embodiment of the present disclosure, two conditions, namely, a first selection condition and a second selection condition, can be promised in the protocol, and after the user equipment determines a transmission beam for the unlicensed uplink channel, it can determine a detection beam for the unlicensed uplink channel based on at least one of the two conditions, and perform LBT detection for the unlicensed uplink channel on the detection beam.

[0132] An embodiment of the present disclosure provides a method for determining a detection beam for an unlicensed uplink channel, which is applied to the user equipment 101. The method includes steps S110d to S140d.

[0133] In step S110d, first beam setting information is received from the network device, where the first beam setting information indicates a transmission beam for transmitting the unlicensed uplink channel.

[0134] In step S120d, one or more detection beams are determined based on the transmission beam indicated by the first beam setting information and the first selection condition promised by the protocol.

[0135] In step S130d, based on a second selection condition, one detection beam of the one or more detection beams is determined as a detection beam that performs LBT for the unlicensed uplink channel.

[0136] In step S140d, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0137] In some possible embodiments, the first selection condition is at least: the detection beam is the transmit beam; The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship; or The detection beam is a detection beam associated with the transmission beam.

[0138] In some possible embodiments, the second selection condition is at least: The beam width is the largest at the set attenuation. or The spatial relationship information index (SRS index) is the smallest.

[0139] Four examples are given below.

[0140] In Example 1, The first selection condition is condition 1. The established relationship is that the 3 dB beamwidth of the transmit beam is within the 3 dB beamwidth of the detect beam, and the second selection condition is condition 4.

[0141] The user equipment determines the transmission beam for the unlicensed uplink channel based on the first beam setting information, and then determines that the beams that satisfy the set relationship are beam A, beam B, and beam C based on condition 1. Among beam A, beam B, and beam C, beam A has the largest 3 dB beam width.

[0142] In this case, the user equipment can determine beam A as the detection beam for this unlicensed uplink channel based on condition 4, and use beam A to perform LBT detection for this unlicensed uplink channel.

[0143] In Example 2, The first selection condition is condition 2, where the relationship established is that the 3 dB beamwidth of the transmit beam is within the 3 dB beamwidth of the detect beam. The second selection condition is condition 5.

[0144] The user equipment determines the transmission beam for the unlicensed uplink channel based on the first beam setting information, and then determines that the beams that satisfy the set relationship are beam A, beam B, and beam C based on condition 2. Among beam A, beam B, and beam C, beam B has the smallest SRS index.

[0145] In this case, the user equipment can determine beam B as the detection beam for this unlicensed uplink channel based on condition 5, and use beam B to perform LBT detection for this unlicensed uplink channel.

[0146] In Example 3, The first selection condition is condition 3, in which three beams, namely beam A, beam B, and beam C, are associated with the transmission beam of the unlicensed uplink channel. The second selection condition is condition 4, in which the set attenuation is 3 dB.

[0147] The user equipment determines a transmission beam for the unlicensed uplink channel based on the first beam setting information, and then determines beam A, beam B, and beam C associated with the transmission beam based on condition 3. Of beam A, beam B, and beam C, beam A has the largest 3 dB beam width.

[0148] In this case, the user equipment can determine beam A as the detection beam for this unlicensed uplink channel based on condition 4, and use beam A to perform LBT detection for this unlicensed uplink channel.

[0149] In Example 4, The first selection condition is condition 3, in which three beams, namely beam A, beam B, and beam C, are associated with the transmission beam of the unlicensed uplink channel. The second selection condition is condition 5.

[0150] The user equipment determines a transmission beam for the unlicensed uplink channel based on the first beam setting information, and then determines beam A, beam B, and beam C associated with the transmission beam based on condition 3. Of beam A, beam B, and beam C, beam B has the smallest SRS index.

[0151] In this case, the user equipment can determine beam B as the detection beam for this unlicensed uplink channel based on condition 5, and use beam B to perform LBT detection for this unlicensed uplink channel.

[0152] In an embodiment of the present disclosure, a first selection condition and a second selection condition can be set, and after the user equipment determines a transmission beam for an unlicensed uplink channel, it can sequentially determine a detection beam for this unlicensed uplink channel based on the first selection condition and the second selection condition, and then perform LBT detection for this unlicensed uplink channel using this detection beam.
