Description

[0001] This application is a divisional application. The original application has the application number 201980001358.7, the application date is July 16, 2019, and the invention title is "Data Transmission Method, Apparatus and Storage Medium". Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a data transmission method, apparatus and storage medium. Background Technology

[0003] In unlicensed spectrum, licensed assisted access (LAA) employs a listen-before-talk (LBT) channel access mechanism.

[0004] In scenarios where a terminal has multiple antenna panels, the active bandwidth part (BWP) configured for the terminal on each panel is the same, meaning the bandwidth and spectrum location are identical. In New Radio unlicensed (NR-U) spectrum, the bandwidth of the active BWP can be up to the same as the component carrier (CC) bandwidth. In NR-U, the maximum bandwidth on each CC can reach 100MHz or even 400MHz, while the maximum LBT (channel detection bandwidth unit) is 20MHz. Therefore, for each terminal, the active BWP can contain multiple LBTs. Furthermore, in multi-panel scenarios, the terminal needs to perform channel detection before transmitting uplink information.

[0005] In multi-panel scenarios, how to perform channel detection across multiple panels, and how to reasonably allocate resources for terminals to send uplink information across multiple panels when the active BWP contains multiple LBT channel detection bandwidth units, are problems that need to be solved.

[0063] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0064] The resource allocation method provided in this disclosure can be applied to... Figure 1 In the wireless communication system 100 shown. See also Figure 1 As shown, the wireless communication system 100 includes a network device 110 and a terminal 120. The terminal 120 is connected to the network device 110 via wireless resources and performs data transmission and reception.

[0065] Understandable, Figure 1 The wireless communication system 100 shown is for illustrative purposes only. The wireless communication system 100 may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0066] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0067] Furthermore, the network device 110 involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (EB), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited. In this disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within that coverage area (cell).

[0068] Furthermore, the terminal 120 involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0069] In this embodiment, network device 110 and terminal 120 can operate on unlicensed spectrum. Before using unlicensed spectrum, network device 110 and terminal 120 need to use a listen-before-talk (LBT) channel access mechanism to perform channel detection. LBT, also known as channel listening, specifically refers to the process where a transmitting node listens to the channel before transmitting data, and only after successful channel listening can data transmission proceed. During channel listening, the transmitting node detects the Received Signal Strength Indication (RSSI) value on the surrounding unlicensed spectrum. If the RSSI value is higher than a threshold, it indicates that other devices are using the unlicensed spectrum, so the transmitting node cannot use it temporarily; otherwise, it indicates that no other devices are using the unlicensed spectrum, so the transmitting node can use the unlicensed spectrum for data transmission.

[0070] Terminal 120 may have one or more antenna panels.

[0071] In the LAA unlicensed spectrum, the maximum bandwidth on each CC (i.e., each cell) is 20MHz, while the maximum LBT channel detection bandwidth is 20MHz. Therefore, there is only one LBT channel detection bandwidth on each CC, so the channel detection results on the entire CC are consistent. Either the entire bandwidth is idle, or the entire bandwidth is occupied by other devices.

[0072] In NR-U, the maximum channel bandwidth per carrier can reach 400MHz. However, considering the capabilities of terminal 120, the maximum bandwidth supported by terminal 120 can be less than 400MHz, and terminal 120 can be configured on multiple small bandwidth parts (BWPs). Network device 110 can configure more than one BWP for terminal 120. In this case, network device 110 needs to tell the terminal which BWP to operate on, i.e., which BWP to activate. This activated BWP can be called the active BWP. Terminal 120 transmits on the corresponding active BWP. In unlicensed frequency bands, network devices or terminals also need to perform channel sensing before transmitting on an active BWP; information can only be transmitted when the channel is empty. In NR-U, the maximum bandwidth per CC can reach 100MHz or even 400MHz, while the maximum LBT channel detection bandwidth unit is 20MHz. Therefore, for each terminal, the active BWP can contain multiple LBT channel detection bandwidth units (BWUs).

[0073] Currently, in scenarios where terminal 120 contains multiple panels, the active BWP configured on the terminals across multiple panels is identical, meaning the bandwidth and spectrum location are the same. For example, before channel detection, the uplink active BWP configured by network device 110 for terminal 120 includes, for instance, the active BWP configured by network device 110 for terminal 120. Figure 2 The diagram shows five LBT BWUs. Before sending uplink information, terminal 120 needs to perform channel detection. How these multiple panels perform channel detection, and which BWUs on which panels the terminal sends uplink information when channel detection is idle in a portion of the LBT channel detection bandwidth units of the currently active BWP, are issues that need to be addressed.

[0074] This disclosure provides a data transmission method in which, in a scenario where the terminal has multiple panels, the multiple panels independently perform channel detection and transmit uplink information such as uplink signaling or data based on the BWU (Broadband Unknown) detected by the multiple panels as an idle channel, thereby improving spectrum efficiency while reducing terminal power consumption.

[0075] Figure 3 This is a flowchart illustrating a data transmission method according to an exemplary embodiment, such as... Figure 3 As shown, this data transmission method is used in a terminal and includes the following steps.

[0076] In step S11, one or more BWUs are selected as a subset of the first channel idle BWU set.

[0077] In this disclosure, the terminal has multiple panels, which can be understood as having at least two panels. Each of the at least two panels performs channel detection on each BWU to be detected, and determines that each panel detects a BWU with an idle channel.

[0078] In this disclosure, the first BWU set is determined based on the channel idle BWUs detected by each panel of the terminal on the active BWP.

[0079] In step S12, one or more of the at least two panels send uplink information on one or more BWUs in the first BWU subset.

[0080] In this disclosure, each panel transmits uplink information on the same BWU or different BWUs. The uplink information includes an uplink reference signal, a sounding reference signal (SRS), a demodulation reference signal (DMRS), control signals and / or data carried on the Physical Uplink Control Channel (PUCCH), control signals and / or data carried on the Physical Uplink Share Channel (PUSCH), and a random access preamble carried on the Physical Random Access Channel (PRACH).

[0081] In this disclosure, in scenarios where the terminal has multiple panels, each panel independently performs channel detection and transmits uplink information such as uplink signaling or data based on the BWU (Broadband Unlocked) detected by the multiple panels as an idle channel, thereby improving spectrum efficiency while reducing terminal power consumption.

[0082] The data transmission methods mentioned above will be explained below in conjunction with practical applications.

[0083] This disclosure first describes the process of channel detection for each panel of the terminal.

[0084] In this disclosure, if the terminal needs to send uplink information through multiple panels, each panel performs channel detection before sending the uplink information. The BWU for channel detection is determined based on downlink control information (DCI) or uplink unlicensed (UL grant free) resource pre-configuration signaling. For example, the terminal determines whether uplink information needs to be sent on multiple panels, and which BWUs on the active BWP should perform channel detection and send uplink information, in the following manner:

[0085] In one example, DCI signaling is downlink resource scheduling information. When a network device sends DCI signaling to a terminal that schedules uplink information on a designated BWU on an active BWP, it uses multiple panels to perform channel detection on that designated BWU and sends uplink information using multiple panels.

[0086] In another example, the network device pre-configures resources on some BWUs for UL grant-free by sending Radio Resource Control (RRC) and / or Media Access Control (MAC) signaling. Then, the terminal uses multiple panels to perform channel detection and send uplink information on the pre-configured BWUs to improve reliability or throughput, etc.

[0087] In another example, the terminal independently determines which BWUs in multiple panels will perform channel detection and sends uplink information. For instance, when there is no downlink control information or uplink unlicensed resource pre-configuration signaling, the terminal can perform channel detection on all BWUs on the active BWP and send uplink information on the BWUs where the channel is detected to be idle.

[0088] For ease of description, the BWU used for channel detection of multiple panels based on DCI signaling, UL grant-free resource pre-configuration signaling, or determined by the terminal itself in this disclosure will be referred to as the BWU to be detected.

[0089] Furthermore, in this disclosure, when each panel of the terminal performs channel detection on each BWU to be channel detected, each panel selects a channel detection mechanism and / or channel detection parameters according to the channel detection priority of the uplink information to be transmitted, and each panel performs channel detection on each BWU to be channel detected according to its selected channel detection mechanism and / or channel detection parameters.

[0090] In this disclosure, the channel detection mechanism includes Cat.2 and Cat.4. Channel detection parameters include contention window size, maximum channel occupancy time, and parameters used to determine the time granularity.

[0091] The Cat.2 channel detection mechanism is a single detection; if the channel is idle within 25µs, it indicates that the channel can be occupied, but the channel occupation time is short, such as 1ms. Cat.4 is a channel detection mechanism based on an adjustable contention window. First, it checks if the channel is idle at a first-time granularity. If the channel is idle, a random number N is generated between 0 and the CWS value, and then the channel is checked again at a second-time granularity. If idle, the random number N is decremented by 1; otherwise, the channel is checked again at the first-time granularity. If idle, the random number N is decremented by 1, and the process switches to checking for idleness at the second-time granularity, and so on... When the random number N decreases to 0, it indicates that the channel is idle, and channel occupation begins. After the maximum channel occupation time ends, channel detection needs to be performed again. The first-time granularity is 16µs + M * 9µs, where the value of M is determined by mp (priority parameter). Different priorities result in different values ​​for M. The second-time granularity is 9µs. Different Cat.4 priorities result in different values ​​for M, CWS, and channel occupation time. For example, the higher the priority, the smaller the M and CWS, and the shorter the channel occupation time. This makes it easier to seize the channel, but the occupation time is relatively short. This type of priority is generally used for latency-sensitive services.

[0092] In this disclosure, the channel detection priority for uplink information to be transmitted is the same for each antenna panel, and the selected channel detection mechanism is the same.

[0093] In this disclosure, when channel detection is performed on multiple BWUs for a certain antenna panel, each BWU can perform channel detection independently, or a primary BWU can be selected for Cat.4 channel detection. Other auxiliary BWUs only need to detect channel idleness within 25µs before the primary BWU's N=0; in this case, both the primary and auxiliary BWUs will detect the channel as idle. When multiple BWUs on various antenna panels perform channel detection using the primary BWU method, the primary BWU for each antenna panel can be selected independently.

[0094] In this disclosure, each of the multiple panels in the terminal independently detects its own channel status, such as using the Cat.4 channel detection mechanism, without distinguishing between a primary BWU and a secondary BWU.

[0095] In this disclosure, when the terminal has multiple panels, the multiple panels independently select the channel detection mechanism and channel detection parameters according to the priority of the uplink information sent, and independently perform channel detection, thereby improving spectrum efficiency while reducing terminal power consumption.

[0096] In this disclosure, multiple panels of the terminal use the same active BWP. The terminal determines the active BWP for transmitting uplink information using different methods based on the different channel detection results obtained from the LBT BWU detection of each antenna panel in the active BWP. The following will explain the different processing methods for different channel detection results in conjunction with practical applications.

[0097] In this disclosure, to inform the network device which BWUs (Browser Wireless Units) have actually detected as idle and / or which BWUs the terminal is actually using to transmit uplink information, the terminal needs to send an indication signaling message to the network device. This indication signaling message can also include the channel occupancy time of each BWU. This has two advantages: first, the network device only needs to receive uplink information on the BWUs detected as idle or actually used for uplink information transmission by the terminal; second, during the channel occupancy time, when the terminal is not using these idle BWUs, the network device can use those idle BWUs to transmit downlink information.

[0098] In one implementation, each of the at least two panels contains the same channel idle BWUs detected by the active BWP. The BWUs in the first BWU set are the set of identical channel idle BWUs detected by each of the at least two panels.

[0099] There are two examples where each panel has the same Channel Idle Us (BWUs) detected by the active BWP: Example 1: All antenna panels detect identical Channel Idle Us in the active BWP currently used by the terminal; that is, for a given terminal's active BWP, the detection results are the same for all antenna panels. For example, in... Figure 2 In Example 2, Panel #0 detects two free channel BWUs (BWUs): BWU #0 and BWU #1. Panel #1 also detects two free channel BWUs: BWU #0 and BWU #1. In Example 2, the free channel BWUs detected by each antenna panel in the currently used active BWP of the terminal are the same. For example, in... Figure 2 In the diagram, Panel#0 detects two idle channel BWUs, BWU#0 and BWU#1, while Panel#1 detects only one idle channel BWU, BWU#0.

[0100] The following disclosure describes an implementation method for determining a first subset of BWUs in two examples where each panel detects the same BWUs in the channel idle BWUs detected by the active BWP.

[0101] Example 1: The channel idle BWU detected by each panel in the active BWP currently used by the terminal is exactly the same.

[0102] In this disclosure, when all panels detect identical Channel Idle Units (BWUs) in the active BWP currently used by the terminal, the terminal uses these identical BWUs as a first set of BWUs. The terminal selects one or more BWUs from the first set of BWUs as a first subset of BWUs and uses this first subset of BWUs to send uplink information.

[0103] Furthermore, in this disclosure, the terminal needs to send indication information, which is used to indicate to each panel which BWUs have detected an idle channel, and / or which BWUs on which the panel has sent uplink information. The terminal informs the network device by sending the indication information which BWUs have detected an idle channel, or on which BWUs the terminal has sent uplink information. Then, during the subsequent channel occupancy period, the network device receives the uplink information sent by the terminal on the corresponding BWUs.

[0104] In one implementation, the terminal sends the instruction information in the following manner:

[0105] Indication information is sent based on the following: uplink DMRS; uplink reference signal, such as SRS; whether the BWU channel is idle as indicated by PUCCH; whether the BWU channel is idle as indicated by PUSCH; whether the BWU channel is idle as indicated by both DMRS and PUCCH; whether the BWU channel is idle as indicated by both DMRS and PUSCH; signals transmitted on an idle BWU, such as shockwave-like signals; Wi-Fi preambles, such as Wi-Fi preambles; and random access preambles transmitted on an idle BWU.

[0106] It is understood that in this embodiment of the present disclosure, the BWUs detected by each panel of the terminal are the same, so the terminal uses the same indication information to indicate which BWUs of the channel are detected by each panel of the network device. Furthermore, since the BWUs of the channel detected by each panel of the terminal in this embodiment of the present disclosure are completely identical, each panel of the terminal can send uplink information on the detected BWUs.

[0107] Example 2: The channel idle BWU portion detected by each panel in the active BWP currently used by the terminal is the same.

[0108] In this disclosure, if the channel idle BWUs detected by each antenna panel in the active BWP currently used by the terminal are partially the same and partially different, then the channel idle BWUs detected by each antenna panel that are the same are used as a first set of BWUs, and one or more BWUs are selected from the first set of BWUs as a first subset of BWUs, and uplink transmission is performed based on the first subset of BWUs. In other words, in this disclosure, if the channel idle BWUs detected by each antenna panel in the active BWP currently used by the terminal are partially the same and partially different, then a subset of the intersection of the channel idle BWUs detected by each antenna panel is used for uplink transmission. For example, in... Figure 2 In the above, the channel idle BWUs detected by Panel#0 are BWU#0 and BWU#1, and the channel idle BWU detected by Panel#1 is BWU#0. Therefore, BWU#0 is determined as the first BWU subset.

[0109] Furthermore, in this disclosure, the terminal needs to send indication information, which is used to indicate the channel idle BWUs detected by each panel, and / or the BWUs on which each panel transmits uplink information. The terminal informs the network device by sending the indication information which BWUs detect channel idleness, and / or on which BWUs the terminal transmits uplink information; that is, the terminal selects a subset from the set of BWUs that detect channel idleness for uplink transmission. The network device receives the uplink information sent by the terminal on the corresponding BWU. Furthermore, since each panel transmits uplink information on the same BWU, the indication information can be sent together for each panel. This is because the network device needs to receive the terminal's uplink transmission on the BWUs on which the terminal transmits uplink information based on the indication information sent by the terminal, or use the idle BWU for downlink transmission when the terminal does not transmit uplink during the channel occupancy period.

[0110] In another implementation, the Channel Free BWUs detected by each panel in at least two panels are not entirely the same in the active BWP. The BWUs in the first BWU set are a set consisting of all Channel Free BWUs detected by each panel in at least two panels.

[0111] In this disclosure, the Channel Free BWUs detected by each panel in at least two panels are not completely identical. This can be because the Channel Free BWUs detected by each panel in at least two panels in the active BWP include both the same and different BWUs, or it can be that only the different BWUs are included.

[0112] In this disclosure, when each panel detects different channel idle BWUs in the active BWP, the first BWU set is determined using the following two methods:

[0113] In one implementation, one or more BWUs are selected as a first BWU subset from the first BWU set consisting of all channel-idle BWUs detected by each panel in the active BWP. Uplink transmission is performed based on the first BWU subset to utilize as many channel-idle BWUs as possible detected by each panel. In this disclosure, the first BWU set can be understood as the union of the channel-idle BWUs detected by each panel. The first BWU subset can be understood as a subset of the union of the channel-idle BWUs detected by each panel. The first BWU subset can include one or more BWUs; for example, the maximum number of BWUs in the first BWU subset can be all channel-idle BWUs detected by each panel.

[0114] Furthermore, in this disclosure, the terminal needs to send indication information, which is used to indicate the channel idle BWUs detected by each panel, and / or the BWUs on which each panel transmits uplink information. The terminal informs the network device by sending the indication information which BWUs have detected channel idleness, and / or on which BWUs the terminal has transmitted uplink information; that is, the terminal selects a subset from the set of BWUs that have detected channel idleness for uplink transmission. The network device receives the uplink information sent by the terminal on the corresponding BWUs. Furthermore, since the BWUs on which each panel detects channel idleness may be different, or uplink information may be transmitted on different BWUs, in this disclosure, the terminal sends indication information independently for each panel. This can be understood as follows: when there are differing panels among at least two panels, indication information is sent separately for each panel in each of the differing panels. The differing panels have different BWUs on which they detect channel idleness and / or different BWUs on which they transmit uplink information.

[0115] Understandably, if some BWUs detect idle activity on a certain panel, but the terminal does not send uplink information on that BWU, that BWU is also classified as a BWU on which the terminal did not send uplink information. This is because network devices need to receive uplink transmissions from the terminal on BWUs where the terminal does send uplink information, based on the indication information sent by the terminal.

[0116] In another implementation, the channel idle BWUs detected by the active BWP in at least two panels are not entirely the same. The first BWU set is a set of all channel idle BWUs detected by a specified panel in each panel. The specified panel is the panel that detects the most channel idle BWUs. This method is used to determine the first BWU subset based on the specified panel. For example... Figure 2If Panel#0 detects that there are more BWUs with idle channels, then Panel#0 will be used to send uplink information, and Panel#0 will be the primary BWU when configuring the first subset of BWUs.

[0117] Furthermore, in this disclosure, the terminal needs to send indication information, which is used to indicate the channel idle BWUs detected by each panel, and / or the BWUs on which each panel transmits uplink information. The terminal informs the network device by sending the indication information which BWUs detect channel idleness, and / or on which BWUs the terminal transmits uplink information. The network device receives the uplink information sent by the terminal on the corresponding BWUs. Further still, in this embodiment, uplink information is transmitted only on a designated panel; therefore, in this disclosure, the indication information is sent only to the designated panel, and no indication information needs to be sent to other panels besides the designated panel. Of course, MAC signaling can also be sent to other panels besides the designated panel to instruct the network device to temporarily deactivate that panel.

[0118] This disclosure pertains to situations where at least two panels each contain completely different Channel Free BWUs detected by the active BWP. If one panel detects a Channel Free BWU, and other antenna panels do not detect a Channel Free BWU, then the designated antenna panel is the panel from which the detection side is connected to the Channel Free BWU.

[0119] In the embodiments disclosed above, when the indication information is not sent to each panel individually, the following two methods can be used: In one method, all panels detect an idle BWU as idle, otherwise it is busy; in the other method, as long as one panel detects an idle BWU, it is idle, otherwise it is busy. The same principle applies to BWUs indicating the transmission of uplink information.

[0120] In this disclosure, when the terminal has multiple panels, the multiple panels independently select the channel detection mechanism and channel detection parameters according to the priority of the uplink information to be sent, independently perform channel detection, and perform uplink transmission according to the channel idle BWU detected by the multiple panels. At the same time, the terminal informs the network device which BWU each panel of the terminal detected channel idle and / or performed uplink transmission, thereby improving spectrum efficiency while reducing terminal power consumption.

[0121] Based on the same concept, embodiments of this disclosure also provide a data transmission device.

[0122] It is understood that the data transmission apparatus provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.
