Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus, and readable storage medium for determining a detection beam for an unlicensed uplink channel. Background Technology

[0002] In unlicensed spectrum, before a transmitter occupies a channel to send data, it typically needs to listen to the channel, a process known as clear channel assessment (CCA). If the transmitter determines the channel is idle after CCA, it can occupy the channel to send data; otherwise, it cannot. This channel is generally referred to as the unlicensed uplink channel, and the above process is generally known as the listen-before-talk (LBT) channel access mechanism in unlicensed spectrum.

[0003] On unlicensed uplink channels, either omnidirectional LBT or directional LBT can be performed. Omnidirectional LBT corresponds to using an omnidirectional beam for LBT, while directional LBT corresponds to using a specific directional beam for LBT. Determining the corresponding detection beam (i.e., the beam used for LBT) in directional LBT is a problem that needs to be solved. Summary of the Invention

[0104] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station.

[0106] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to a communication system 100. (Refer to...) Figure 2 , Figure 2 This is a flowchart illustrating a method for determining a detection beam for an unlicensed uplink channel according to an exemplary embodiment, such as... Figure 2 As shown, this method includes:

[0107] Step S21, network device 102 sends the first beam configuration information to user equipment 101;

[0108] Step S22: User equipment 101 receives the first beam configuration information sent by network device 102;

[0109] Step S23: User equipment 101 determines the detection beam for performing LBT detection on the unlicensed uplink channel based on the first beam configuration information;

[0110] Optionally, the method may further include step S24, in response to determining the detection beam for performing LBT detection on the unlicensed uplink channel, user equipment 101 may perform LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0111] The first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0112] Among them, the detection beam for performing LBT detection on the unlicensed uplink channel is the detection beam for performing directional LBT detection on the unlicensed uplink channel.

[0113] In some possible implementations, this method for determining the detection beam of the unlicensed uplink channel is applied to the unlicensed frequency band from NR52.6 GHz to 71 GHz.

[0114] The following examples illustrate this.

[0115] Example 1,

[0116] This corresponds to the Physical Uplink Control Channel (PUCCH). The user equipment can receive higher-layer signaling from the network equipment. The higher-layer signaling includes first beam configuration information, which includes multiple spatial relation information. These multiple spatial relation information correspond to multiple transmit beams for transmitting unlicensed uplink channels. In other words, the multiple spatial relation information are used to indicate the SRS transmit beams.

[0117] SRS stands for Sounding Reference Signal, which generally refers to the sounding reference signal, and can also be called the uplink reference signal. The main functions of SRS are uplink channel state information acquisition, downlink channel state information acquisition, and beam management.

[0118] The user equipment also needs to receive MAC CE signaling from the network equipment. The MAC CE signaling is used to activate one of the multiple transmit beams that transmit unlicensed uplink channels. The activated beam is used as the transmit beam to transmit the PUCCH channel.

[0119] Example 2,

[0120] This corresponds to the Physical Uplink Shared Channel (CG-PUSCH). User equipment can receive RRC (Radio Resource Control) layer signaling from network equipment. The RRC layer signaling includes first beam configuration information, which indicates SRS resources to implicitly indicate the transmit beam corresponding to the CG-PUSCH.

[0121] Example 3,

[0122] This corresponds to the dynamically scheduled Physical Uplink Shared channel (PUSCH). The user equipment can receive a scheduled DCI from the network equipment. The scheduled DCI includes first beam configuration information, which is used to indicate an SRS resource to implicitly indicate the transmission beam corresponding to the PUSCH.

[0123] In the embodiments of this disclosure, the network device sends first beam configuration information to the user equipment, enabling the user equipment to determine the detection beam for performing Talk-Before-Talk (LBT) detection on the unlicensed uplink channel based on the first beam configuration information. This allows the user equipment to determine a reasonable detection beam without the network device needing to indicate relevant information about the detection beam, thus saving transmission resources.

[0124] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. (Refer to...) Figure 3 , Figure 3 This is a flowchart illustrating a method for determining a detection beam for an unlicensed uplink channel according to an exemplary embodiment, such as... Figure 3 As shown, this method includes:

[0125] This method includes:

[0126] Step S110a: Receive first beam configuration information from the network device; wherein the first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0127] Step S120a: Determine the detection beam for performing Listen-Before-Speak (LBT) detection on the unlicensed uplink channel based on the first beam configuration information;

[0128] Optionally, the method further includes step S130a, in response to determining the detection beam for performing Listen-Before-Talk (LBT) detection on the unlicensed uplink channel, LBT detection can be performed on the unlicensed uplink channel based on the determined detection beam.

[0129] Among them, the detection beam for performing LBT detection on the unlicensed uplink channel is the detection beam for performing directional LBT detection on the unlicensed uplink channel.

[0130] In some possible implementations, the detection beam used to perform LBT detection on unlicensed uplink channels is an omnidirectional beam.

[0131] In some possible implementations, the unlicensed uplink channel is PUCCH, CG-PUSCH, or PUSCH.

[0132] In the embodiments of this disclosure, the user equipment receives first beam configuration information from the network device to determine the transmission beam for transmitting the unlicensed uplink channel, and then determines the detection beam for performing READ-LOBT LBT detection on the unlicensed uplink channel based on the transmission beam. Thus, the user equipment can determine a reasonable detection beam without the network device indicating relevant information about the detection beam, saving transmission resources.

[0133] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. This method includes:

[0134] Step S110b: Receive higher-layer signaling from the network device; wherein, the higher-layer signaling includes LBT configuration information, and the LBT configuration information indicates that the LBT mode is directional LBT.

[0135] Step S120b: Receive the first beam configuration information from the network device;

[0136] Step S130b: Determine the detection beam for performing Listen-Before-Speak (LBT) detection on the unlicensed uplink channel based on the first beam configuration information.

[0137] Optionally, the method further includes step S140b, in response to determining the detection beam for performing Listen-Before-Talk (LBT) detection on the unlicensed uplink channel, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0138] Once the user equipment receives higher-layer signaling from the network equipment, it can determine whether the LBT mode is directional LBT mode based on the LBT configuration information in the higher-layer signaling.

[0139] The first beam configuration information is used to indicate the transmission beam for transmitting the unlicensed uplink channel. The user equipment receives the first beam configuration information from the network equipment to determine the transmission beam for transmitting the unlicensed uplink channel, and then determines the detection beam for performing READ-LOCK LBT detection on the unlicensed uplink channel based on the transmission beam.

[0140] In the embodiments of this disclosure, the user equipment receives higher-layer signaling and first beam configuration information from the network device to determine the LBT mode and detection beam. Then, the user equipment performs LBT detection on the unlicensed uplink channel using the detection beam in a directional LBT mode. This allows the user equipment to determine a reasonable detection beam without the network device needing to indicate relevant information about the detection beam, thus saving transmission resources.

[0141] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. (Refer to...)

[0150] In some possible implementations, the second selection condition includes at least:

[0151] The maximum beamwidth for setting attenuation

[0152] or

[0153] The spatial relationship information index is the smallest.

[0154] In the embodiments of this disclosure, conditions can be agreed upon in the protocol. After the user equipment determines the transmission beam of the unlicensed uplink channel, it can determine the detection beam of this unlicensed uplink channel based on the conditions agreed upon in the protocol, and then use this detection beam to perform LBT detection on this unlicensed uplink channel.

[0155] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. This method includes:

[0156] Step S110d: Receive first beam configuration information from the network device; wherein the first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0157] Step S120d: Based on the transmission beam indicated by the first beam configuration information and the first selection condition agreed upon in the protocol, determine the detection beam for performing LBT detection on the unlicensed uplink channel.

[0158] Optionally, the method further includes step S130d, in response to determining the 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.

[0159] In some possible implementations, the first selection condition includes at least:

[0160] The detection beam is the same as the transmission beam;

[0161] The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship;

[0162] or

[0163] The detection beam is the detection beam associated with the transmit beam.

[0164] The following three examples illustrate this.

[0165] Example 1,

[0166] The first selection condition is condition 1, namely "the detection beam is the transmission beam". The user equipment determines beam A as the transmission beam based on the first beam configuration information. The user equipment can directly determine beam A as the detection beam based on condition 1, and then use beam A to perform LBT detection.

[0167] Example 2,

[0168] The first selection condition is condition 2, namely, "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 3dB beamwidth of the transmission beam is within the 3dB beamwidth of the detection beam. Based on the first beam configuration information, the user equipment determines that the transmission beams of the unlicensed uplink channel include beams A, B, and C. Based on condition 2, beam A is determined to be the beam satisfying the set relationship. Beam A is then selected as the detection beam, and LBT detection is performed using beam A.

[0169] Example 3,

[0170] The first selection condition is condition 3, namely, "the detection beam is the detection beam associated with the transmission beam." Here, the base station can associate three beams with the transmission beam of the unlicensed uplink channel, abbreviated as beam E, beam F, and beam G. The user equipment determines the transmission beam of the unlicensed uplink channel and condition 3 based on the first beam configuration information, identifying beams E, F, and G as satisfying the set relationship.

[0171] In the embodiments of this disclosure, a first selection condition can be agreed in the protocol. After the user equipment determines the transmission beam of the unlicensed uplink channel, it can determine the detection beam of the unlicensed uplink channel based on the first selection condition, and then perform LBT detection on the unlicensed uplink channel using the detection beam.

[0172] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. This method includes:

[0173] Step S110e: Receive first beam configuration information from the network device; wherein the first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0174] Step S120e: Based on the transmission beam indicated by the first beam configuration information and the second selection condition agreed upon in the protocol, determine the detection beam for performing LBT detection on the unlicensed uplink channel.

[0175] Optionally, the method may further include step S130e, in response to determining the 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.

[0176] In some possible implementations, the second selection condition includes at least:

[0177] The maximum beamwidth for setting attenuation

[0178] or

[0179] The spatial relationship information index is the smallest.

[0180] The following two examples illustrate this.

[0181] Example 1,

[0182] The first selection condition is condition 4, namely "the beamwidth with the set attenuation is the largest". The user equipment determines beams A and B as the transmit beams based on the first beam configuration information. The user equipment can determine that the beam with the largest beamwidth with the set attenuation among beams A and beam B is beam A based on condition 4, and then determine beam A as the detection beam, and then use beam A to perform LBT detection.

[0183] Example 2,

[0184] The first selection condition is condition 5, namely "minimum spatial relationship information index". The user equipment determines beam A and beam B as the transmission beams based on the first beam configuration information. The user equipment can determine the beam with the smallest spatial relationship information index between beam A and beam B based on condition 5, and then determine beam B as the detection beam, and then use beam B to perform LBT detection.

[0185] In the embodiments of this disclosure, a second selection condition can be agreed upon in the protocol. After determining the transmission beam of the unlicensed uplink channel, the user equipment can determine the detection beam of this unlicensed uplink channel based on the second selection condition, and then perform LBT detection on this unlicensed uplink channel using this detection beam. Of course, it should be understood that in the above example, the second selection condition is based on the selection result of the first selection condition. However, the implementation of the second selection condition does not necessarily depend on the first selection condition. That is, multiple detection beams can be determined as a candidate set through other means, and then a detection beam can be selected through the second selection condition.

[0186] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. This method includes:

[0187] Step S110c: Receive first beam configuration information from the network device; wherein the first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0188] Step S120c: Based on the transmission beam indicated by the first beam configuration information and the first and second selection conditions agreed upon in the protocol, determine the detection beam for performing LBT detection on the unlicensed uplink channel;

[0189] In step S130c, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0190] In some possible implementations,

[0191] The first selection criteria must include at least:

[0192] The detection beam is the same as the transmission beam;

[0193] The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship;

[0194] or

[0195] The detection beam is the detection beam associated with the transmit beam.

[0196] In some possible implementations, the second selection condition includes at least:

[0197] The maximum beamwidth for setting attenuation

[0198] or

[0199] The spatial relationship information index is the smallest.

[0200] The following example illustrates this.

[0201] For example:

[0202] The first selection condition is condition 3, which is "the detection beam is the detection beam associated with the transmission beam", and the second selection condition is condition 5, which is "the beamwidth with the set attenuation is the largest".

[0203] The user equipment (UE) determines beams A and B as transmit beams based on the first beam configuration information. If the UE determines that beam A is the one that simultaneously satisfies conditions 4 and 5, then beam A is designated as the detection beam, and LBT detection is performed using beam A.

[0204] In the embodiments of this disclosure, two conditions can be agreed in the protocol, namely a first selection condition and a second selection condition. After the user equipment determines the transmission beam of the unlicensed uplink channel, it can determine the detection beam of the unlicensed uplink channel based on at least one of the two conditions, and then perform LBT detection on the unlicensed uplink channel using the detection beam.

[0205] This disclosure provides a method for determining the detection beam of an unlicensed uplink channel, applied to user equipment 101. This method includes:

[0206] Step S110d: Receive first beam configuration information from the network device; wherein the first beam configuration information is used to indicate the transmit beam for transmitting the unlicensed uplink channel.

[0207] Step S120d: Based on the transmission beam indicated by the first beam configuration information and the first selection condition agreed upon in the protocol, determine one or more detection beams;

[0208] Step S130d: Based on the second selection condition, determine one of the one or more detection beams as the detection beam for performing LBT on the unlicensed uplink channel;

[0209] In step S140d, the user equipment performs LBT detection on the unlicensed uplink channel based on the determined detection beam.

[0210] In some possible implementations, the first selection condition includes at least:

[0211] The detection beam is the same as the transmission beam;

[0212] The coverage direction of the detection beam and the coverage direction of the transmission beam satisfy a set relationship;

[0213] or,

[0214] The detection beam is the detection beam associated with the transmit beam.

[0215] In some possible implementations, the second selection condition includes at least: the beamwidth at which the attenuation is set is the largest;

[0216] or,

[0217] The Spatial Relationship Information Index (SRS index) is the smallest.

[0218] The following four examples illustrate this.

[0219] Example 1,

[0220] The first selection condition is condition 1. The relationship is set such that the 3dB beamwidth of the transmitted beam is within the 3dB beamwidth of the detected beam. The second selection condition is condition 4.

[0221] After the user equipment determines the transmission beam of the unlicensed uplink channel based on the first beam configuration information, it determines beams A, B, and C that satisfy the set relationship based on condition 1. Among beams A, B, and C, beam A has the largest 3dB beamwidth.

[0222] In this case, the user equipment can determine beam A as the detection beam for this unlicensed uplink channel based on condition 4, and then use beam A to perform LBT detection on this unlicensed uplink channel.

[0223] Example 2,

[0224] The first selection condition is condition 2, which sets the relationship to the 3dB beamwidth of the transmitted beam being within the 3dB beamwidth of the detected beam. The second selection condition is condition 5.

[0225] After the user equipment determines the transmission beam of the unlicensed uplink channel based on the first beam configuration information, it determines beams A, B, and C that satisfy the set relationship based on condition 2. Among beams A, B, and C, beam B has the smallest SRS index.

[0226] In this case, the user equipment can determine beam B as the detection beam for this unlicensed uplink channel based on condition 5, and then use beam B to perform LBT detection on this unlicensed uplink channel.

[0227] Example 3,

[0228] The first selection condition is condition 3, where the unlicensed uplink channel transmits three beams, referred to as beam A, beam B, and beam C. The second selection condition is condition 4, where the attenuation is set to 3dB.

[0229] After determining the transmit beam of the unlicensed uplink channel based on the first beam configuration information, the user equipment determines the beams A, B, and C associated with the transmit beam based on condition 3. Among beams A, B, and C, beam A has the largest 3dB beamwidth.

[0230] In this case, the user equipment can determine beam A as the detection beam for this unlicensed uplink channel based on condition 4, and then use beam A to perform LBT detection on this unlicensed uplink channel.

[0231] Example 4,

[0232] The first selection condition is condition 3, where the unlicensed uplink channel transmits three beams, referred to as beam A, beam B, and beam C. The second selection condition is condition 5.

[0233] After determining the transmit beam of the unlicensed uplink channel based on the first beam configuration information, the user equipment determines the beams A, B, and C associated with the transmit beam based on condition 3. Among beams A, B, and C, beam B has the smallest SRS index.

[0234] In this case, the user equipment can determine beam B as the detection beam for this unlicensed uplink channel based on condition 5, and then use beam B to perform LBT detection on this unlicensed uplink channel.

[0235] In the embodiments of this disclosure, a first selection condition and a second selection condition can be set. After the user equipment determines the transmission beam of the unlicensed uplink channel, it can determine the detection beam of the unlicensed uplink channel based on the first selection condition and the second selection condition in sequence, and then perform LBT detection on the unlicensed uplink channel using the detection beam.
