[0004] --Original application title: A method and apparatus for use in user equipment and base stations for wireless communication Technical Field

[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to communication methods and apparatus that support data transmission on unlicensed spectrum. Background Technology

[0006] In traditional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) systems, data transmission can only occur on licensed spectrum. However, with the rapid increase in traffic volume, especially in some urban areas, licensed spectrum may be insufficient to meet the demand. In Release 13 and Release 14, communication on unlicensed spectrum was introduced into cellular systems for downlink and uplink data transmission. To ensure compatibility with other unlicensed spectrum access technologies, LBT (Listen Before Talk) technology was adopted by LTE's LAA (Licensed Assisted Access) to avoid interference caused by multiple transmitters simultaneously occupying the same frequency resources.

[0007] In LTE Cat 4 LBT (the fourth type of LBT, see 3GPP TR36.889), the transmitter (base station or user equipment) performs a backoff after a certain deferral period. The backoff time is counted in CCA (Clear Channel Assessment) time slots, and the number of backoff time slots is randomly selected by the transmitter within the CWS (Contention Window Size). For downlink transmission, the CWS is adjusted based on the HARQ (Hybrid Automatic Repeat reQuest) feedback corresponding to the data in a previously transmitted reference subframe on the unlicensed spectrum. For uplink transmission, the CWS is adjusted based on whether the data in a previous reference subframe on the unlicensed spectrum includes new data. In LTE, the bandwidth of the LBT is the same as the bandwidth of the corresponding carrier.

[0008] In the 5G NR (New Radio Access Technology) Phase 1 system, to support multiple subcarrier intervals within a single system bandwidth and considering the limited receiving bandwidth of terminals, the concept of BWP (Bandwidth Part) is introduced. When a cell has a large-bandwidth CC (Component Carrier), the base station can divide this large CC into multiple BWPs to accommodate UEs (User Equipment) with different receiving and transmitting bandwidth capabilities. The bandwidth size of the BWP can be flexibly configured. When a UE with a smaller bandwidth communicates with the cell, it can only perform downlink reception or uplink transmission on the smaller-bandwidth BWP. When a UE with a larger bandwidth communicates with the cell, it can perform downlink reception or uplink transmission on the larger-bandwidth BWP. Currently, discussions regarding LBT (Leadership Bandwidth) in 5G NR are underway. Considering that the system bandwidth variation range of NR is larger than that of LTE, traditional LAA (Layered Access) technology needs to be reconsidered, such as the LBT scheme. Summary of the Invention

[0009] Through research, the inventors discovered that a key problem that needs to be solved is how to improve channel access opportunities and more effectively achieve the sharing of unlicensed spectrum resources among multiple transmitting nodes on the unlicensed spectrum of NR systems.

[0010] To address the aforementioned problems, this application discloses a solution. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0011] This application discloses a method for a first node in wireless communication, characterized by comprising:

[0012] Receive T first-type wireless signals, where T is a positive integer greater than 1; perform T access detections on T sub-frequency bands respectively, and transmit T second-type wireless signals in T time-frequency resource blocks respectively;

[0013] Q energy detections are performed in Q time sub-pools in the first sub-frequency band to obtain Q detection values, where Q is a positive integer;

[0014] Wherein, the T sub-frequency bands all include at least one common frequency point, or the T sub-frequency bands all belong to the same carrier; at least one of the T sub-frequency bands is different from the first sub-frequency band; the T first-type wireless signals are respectively associated with the T second-type wireless signals; the reference first-type wireless signal is one of the T first-type wireless signals, and Q is related to only the reference first-type wireless signal among the T first-type wireless signals; the T access detections are respectively used to determine the transmission of the T second-type wireless signals; the reference sub-frequency band is one of the T sub-frequency bands corresponding to the reference first-type wireless signal, and the reference time-frequency resource block is one of the T time-frequency resource blocks corresponding to the reference first-type wireless signal; the selection of the reference time-frequency resource block is related to at least one of the first sub-frequency band and the reference sub-frequency band; the first node is a base station, or the first node is a user equipment.

[0015] As an example, the problem this application aims to solve is that when the bandwidth of the CC or BWP is large, if the bandwidth of the LBT is the same as that of the CC or BWP, the large LBT bandwidth will lead to a lower channel access opportunity. To improve channel access opportunity and more effectively realize the sharing of unlicensed spectrum resources among multiple transmitting nodes, while meeting the requirement of a bandwidth not less than the regulatory requirements (e.g., 20MHz for a 5GHz carrier frequency, 1GHz for a 60GHz carrier frequency), selecting a narrowband LBT (i.e., a bandwidth smaller than that of the CC or BWP, or in other words, an LBT bandwidth smaller than the transmission bandwidth of the wireless signal) can improve channel access opportunity. Wireless transmission under the narrowband LBT condition is a key problem that needs to be solved.

[0016] As an example, the problem this application aims to solve is that, when using narrowband LBT technology, the bandwidth of the LBT at different times may vary. Calculating the current frequency response frame (CWS) of the current LBT requires determining a reference subframe, and this reference subframe must reflect the interference situation of the current LBT bandwidth. This places new demands on the CWS adjustment method. The above solution considers the current LBT bandwidth and / or previous LBT bandwidth when determining the reference subframe, thus solving this problem and reducing the probability of multiple transmitters simultaneously occupying the same frequency resources, thereby reducing co-channel interference.

[0017] As an example, the essence of the above method is that the T access detections are T LBTs, the T sub-bands are the bandwidths of these T LBTs, the first sub-band is the bandwidth of the current LBT, the reference time-frequency resource block is a reference subframe, and Q is related to CWS. The selection of the reference subframe is related to the bandwidth of the current LBT and / or the bandwidths of the T LBTs. The advantage of using the above method is that it enables CWS to more accurately reflect the interference status of the current LBT bandwidth, thereby configuring an optimal backoff conflict window (Contention Window) for the Q energy detections.

[0018] According to one aspect of this application, the above method is characterized in that the bandwidth of the reference sub-band is equal to the bandwidth of the carrier to which the reference sub-band belongs.

[0019] As an example, the essence of the above method is that the reference sub-band is wideband, the LBT corresponding to the reference sub-band is a wideband LBT, and the frequency band of the current LBT will not exceed the range of the reference sub-band. The advantage of using this method is that, regardless of the bandwidth of the current LBT, selecting the time-frequency resource in the uplink / downlink burst corresponding to the wideband LBT as the reference subframe can reflect the interference status of the current LBT, thereby configuring an optimal backoff conflict window for the Q-order energy detection.

[0020] According to one aspect of this application, the above method is characterized in that t of the T time-frequency resource blocks all include the first sub-frequency band in the frequency domain, where t is a positive integer not greater than T; and the reference time-frequency resource block is one of the t time-frequency resource blocks.

[0021] As an example, the essence of the above method is that the frequency bands of the t LBTs corresponding to the t time-frequency resource blocks each include the frequency band of the current LBT, and the reference subframe corresponds to one of the t time-frequency resource blocks, such as the time-frequency resource block that is closest to the current LBT in time. The advantage of using the above method is that the reference subframe can reflect the interference status of the current LBT, thereby configuring an optimal backoff conflict window for the Q-time energy detection.

[0022] According to one aspect of this application, the above method is characterized in that t of the T time-frequency resource blocks all include the first sub-frequency band in the frequency domain, where t is a positive integer not greater than T; the t1 time-frequency resource blocks among the t time-frequency resource blocks each include the same frequency domain resources as the first sub-frequency band, where t1 is a positive integer not greater than t, and the reference time-frequency resource block is one of the t1 time-frequency resource blocks; or, the frequency domain resources included in any of the t time-frequency resource blocks are not completely the same as the frequency domain resources included in the first sub-frequency band, and the reference time-frequency resource block is one of the t time-frequency resource blocks.

[0023] As an example, the essence of the above method is that if the frequency bands of the t1 LBTs corresponding to the t1 time-frequency resource blocks are all the same as the frequency band of the current LBT, the reference subframe corresponds to one of the t1 time-frequency resource blocks, such as the time-frequency resource block closest to the current LBT in time; otherwise, if the frequency band ranges of the t LBTs corresponding to the t time-frequency resource blocks are all greater than the frequency band range of the current LBT, the reference subframe corresponds to one of the t time-frequency resource blocks, such as the time-frequency resource block closest to the current LBT in time. The advantage of using the above method is that prioritizing the selection of time-frequency resources corresponding to LBTs with the same frequency band as the current LBT for the reference subframe can better reflect the interference status of the current LBT, thereby configuring an optimal backoff conflict window for the Q-time energy detection.

[0024] According to one aspect of this application, the above method is characterized in that the first node is a base station, the T first-type wireless signals respectively indicate whether the T second-type wireless signals are correctly received; the reference second-type wireless signal is one of the T second-type wireless signals to which the reference first-type wireless signal is associated, the reference second-type wireless signal includes W sub-signals, where W is a positive integer; whether the W sub-signals are correctly received is used to determine Q.

[0029] The start time of the time domain resources occupied by the third type of wireless signal is no earlier than the end time of the Q time sub-pools.

[0037] As an example, the device in the first node described above is characterized in that the bandwidth of the reference sub-band is equal to the bandwidth of the carrier to which the reference sub-band belongs.

[0041] As an example, the device in the first node described above is characterized in that the first node is a user equipment, the T first-type wireless signals each include scheduling information of the T second-type wireless signals; the reference second-type wireless signal is one of the T second-type wireless signals to which the reference first-type wireless signal is associated, the reference second-type wireless signal includes V sub-signals, where V is a positive integer; the reference first-type wireless signal is used to determine whether the V sub-signals include new data; whether the V sub-signals include new data is used to determine Q.

[0047] As an example, compared with conventional solutions, this application has the following advantages:

[0048] When the bandwidth of the CC or BWP is large, if the bandwidth of the LBT is the same as that of the CC or BWP, the larger LBT bandwidth will result in a lower channel access opportunity. To improve channel access opportunity and more effectively enable multiple transmitting nodes to share unlicensed spectrum resources, allowing a narrowband LBT (i.e., bandwidth smaller than the CC or BWP, or in other words, LBT bandwidth smaller than the transmission bandwidth of the radio signal) can improve channel access opportunity, provided that the bandwidth is not less than the regulatory requirements (e.g., 20MHz for a 5GHz carrier frequency, 1GHz for a 60GHz carrier frequency).

[0049] - Using narrowband LBT technology, the bandwidth of the LBT of the transmitting node may be different at different times. When calculating the current LBT CWS, it is necessary to determine the reference subframe. This paper proposes to take into account the current LBT bandwidth and / or the previous LBT bandwidth when determining the reference subframe, so that the determination of the reference subframe can reflect the interference situation of the current LBT bandwidth. The optimal backoff conflict window is configured, thereby reducing the probability of multiple transmitters occupying the same frequency resources at the same time, thus reducing the co-channel interference caused by this.

[0204] Example 3

[0206] Appendix Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and control plane. Figure 3The radio protocol architecture for User Equipment (UE) and Base Station Equipment (gNB or eNB) is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the UE and gNB via PHY301. In the user plane, L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not illustrated, a UE may have several upper layers above L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.). PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides header compression for upper layer packets to reduce radio transmission overhead, provides security through packet encryption, and provides handover support between gNBs to the UE. RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among UEs. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and gNB is largely the same for physical layer 301 and L2 layer 305, but header compression functionality for the control plane is absent. The control plane also includes a Layer 3 (L3) RRC (Radio Resource Control) sublayer 306. RRC sublayer 306 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE.

In step S1003, energy detection is performed within a deferral duration. In step S1004, it is determined whether all time slots within this deferral duration are idle. If so, proceed to step S1005 and set the first counter to X1, where X1 is an integer not greater than X; otherwise, return to step S1004. In step S1006, it is determined whether the first counter is 0. If so, proceed to step S1007 and perform wireless transmission within a given time domain resource in the given sub-frequency band; otherwise, proceed to step S1008 and perform energy detection within an additional slot duration. In step S1009, it is determined whether this additional slot duration is idle. If so, proceed to step S1010 and decrement the first counter by 1, then return to step S1006; otherwise, proceed to step S1011 and perform energy detection within an additional deferral duration. Energy detection is performed within the duration; in step S1012, it is determined whether all time slots within this additional delay period are idle. If so, proceed to step S1010; otherwise, return to step S1011.

If the channel is idle, wireless transmission can be performed within the given time domain resources of the given sub-frequency band; otherwise, wireless transmission within the given time domain resources of the given sub-frequency band is abandoned.
