[0002] In an extended reality (XR) application, when a state of an XR device changes, such as a change in pose, pose information is carried in UL data. Meanwhile, such a change in pose or position can cause a change in channel state. Channel measurement and reporting is unrelated to the pose information of the XR device, so the XR device may not be able to timely report the channel state when the pose or position changes, which can cause unnecessary delay and errors in data issued by the network side, and ultimately affect the interactive experience of the user. SUMMARY

[0029] In order to better understand the technical solutions of the embodiments of the present application, the following contents are first introduced:

[0030] XR service

[0031] XR refers to all combined real and virtual environments and human-machine interactions produced by computer technology and wearable devices. It includes Augmented Reality (AR), Mixed Reality (MR), Virtual Reality (VR), and other representative forms, as well as the interpolation areas between them. The level of virtual world ranges from partial sensory input to fully immersive virtual reality. One key aspect of XR is the extension of human experience, especially the experience related to presence (represented by VR) and cognitive acquisition (represented by AR).

[0032] Take the VR service model as an example: packets arrive at equal intervals, and the interval is 1 / FPS seconds. The typical value of Frames Per Second (FPS) is 60 or 120 per second.

[0033] As shown in Figure 1b , the following different types of degrees of freedom are described:

[0034] (1) 3DoF: three rotations around the X, Y, and Z axes and unlimited motion (pitch, yaw, and roll, respectively). A typical use case is that a user sits in a chair to watch 3D 360 VR content on a head-mounted display (HMD) (see Figure 1b (a) in particular).

[0035] (2) 3DoF+: 3DoF with additional limited translational motion along the X, Y, and Z axes (typically head motion). A typical use case is that a user sits in a chair to watch 3D 360 VR content on an HMD, with the ability to move the head slightly up / down, left / right, and forward / backward (see Figure 1b (b) in particular).

[0036] (3) Constrained 6DoF: 6DoF with constrained translational motion along the X, Y, and Z axes (typically two steps of walking distance). A typical use case is that a user freely navigates VR content displayed on an HMD (physically or through dedicated user input means), but within a limited roaming area (see Figure 1b (c) in particular).

[0037] (4) 6DoF: 3DoF with full translational motion along the X, Y, and Z axes. In addition to the 3DoF experience, it also adds (i) up and down movement (heave / sway); (ii) left and right movement (slew / roll); and (iii) forward and backward movement (walk / pant). A typical use case is that a user freely navigates 3D 360 VR content displayed on an HMD (physically or through dedicated user input means) (see Figure 1b (d) in particular).

[0038] SRS trigger reporting mechanism

[0039] Sounding Reference Signal (SRS) is an uplink reference signal in 5G NR, which is used for uplink channel information acquisition, downlink channel information acquisition when satisfying channel reciprocity, and uplink beam management. In the LTE system, SRS can only be configured in the last symbol of each subframe. In the NR system, SRS has more available resource positions, which can be flexibly configured through high-layer signaling.

[0040] According to the high-layer parameter indication, the UE can be configured with one or more SRS resource sets, each of which contains at least one SRS resource. The number of SRS resources contained in each resource set is related to the processing capability of the UE. The high-layer parameter is used to configure the resource set. The 5G SRS resource type (ResourceType) defines whether the SRS is periodic (configured by RRC), semi-persistent (triggered by MAC CE), or aperiodic (triggered by DCI).

[0041] Periodic SRS transmission: the network will configure the terminal with the period of SRS and the time slot offset information within the period, and the terminal will transmit periodically according to the network configuration

[0042] Semi-persistent SRS transmission: similar to periodic SRS, the network will configure the SRS period and time slot offset. Similar to semi-persistent CSI-RS, the network needs to activate or deactivate the semi-persistent SRS transmission through MAC CE signaling.

[0043] Aperiodic SRS transmission: the network triggers the transmission of SRS through DCI command, and the related configuration background is as follows:

[0044] (1) The network configures through RRC: the RRC parameter SRS resource set contains the resource type resourceType field, if the field is configured as aperiodic, the aperiodic field contains aperiodicSRS-ResourceTrigger and aperiodicSRS-ResourceTriggerList, which select one or select two as the trigger state of the set in the trigger candidate state (1, 2, 3).

[0045] (2) The network activates through DCI:

[0046] SRS request, 2 bits as defined in Table 1, for UEs not configured with supplementary uplink in ServingCellConfig of the cell; 3 bits for UEs configured with supplementary uplink in ServingCellConfig of the cell, where the first bit is the non-SUL / SUL indicator as defined in Table 1, and the second and third bits are defined by Table 1. This bit field can also indicate the associated CSI-RS.

[0047] where SRS request is 2 bits for indicating trigger state for UEs not configured with SUL in this cell;

[0048] SRS request is 1 bit for non-SUL / SUL indication and 2 bits for indicating trigger state for UEs configured with SUL in this cell;

[0049] The specific indication is as follows:

[0050] 00 represents not activated;

[0051] 01 represents activating trigger state = 1 or 1 contained in trigger state list;

[0052] 10 represents activating trigger state = 2 or 2 contained in trigger state list;

[0053] 11 represents activating trigger state = 3 or 3 contained in trigger state list;

[0056]

[0057] The method and device provided by the embodiments of the present application will be described in detail below with reference to the specific embodiments and application scenarios.

[0058] Referring to Figure 2 The embodiments of the present application provide a method for sending uplink signals, the execution subject of the method can be a terminal, and the specific steps include:

[0059] Step 201: In the case of meeting the preset condition and / or the preset service information, the terminal performs uplink signal sending related operation;

[0060] Wherein, the uplink signal sending related operation includes at least one of the following:

[0061] transmitting the SRS;

[0062] transmitting the SRS transmission request.

[0063] In the embodiments of the present application, taking the XR application scenario as an example, when the posture of the XR device changes, it may bring changes in the channel state. Of course, in other scenarios, such as terminal positioning scenarios, as the position and posture of the device change, it may also bring changes in the channel state, and the present application does not make specific limitations on the application scenario.

[0064] The above SRS transmission request is mainly used to instruct the network that the terminal has transmitted the SRS.

[0065] It should be noted that the preset condition and / or the preset service information can include any of the following cases: (1) the terminal or the related parameters (such as related information, identifiers, data packets, channels, etc.) of the terminal meet the preset condition; (2) the service information of the terminal is the preset service information; (3) the terminal or the related parameters of the terminal meet the preset condition, and the service information of the terminal is the preset service information.

[0066] In the embodiments of the present application, in the case of meeting the preset condition and / or the preset service information, the terminal performs the uplink signal transmission related operation, which can make the network side more quickly and effectively perceive the change of the channel state, and adjust the parameters of the uplink and downlink transmission according to these changes, so as to further meet the service demand and improve the transmission efficiency.

[0067] In a possible implementation, the preset condition is associated with the preset service information of the terminal, for example: the preset service is the XR service, and the corresponding preset condition is associated with the XR service information, such as the posture information.

[0068] In a possible implementation, the preset condition includes:

[0069] The first target information obtained by the terminal includes at least one of the following:

[0070] (1) a specific Quality of Service (QoS) flow;

[0071] (2) specific QoS synchronization information;

[0072] (3) mapping relationship information between multiple specific QoSs, i.e., association and mapping relationship between multiple data packets, for example, QoS flow 1 depends on QoS flow 2, or there is some correlation between PDB and PER performance indicators, or there is some correlation between data packets, the mapping relationship information can also be referred to as dependency relationship information;

[0073] (4) specific logical channel information;

[0074] (5) specific logical channel information synchronization information;

[0075] (6) mapping relationship information between multiple specific logical channel information, i.e., association and mapping relationship between multiple data packets, for example, logical channel 1 depends on logical channel 2, or there is some correlation between PDB and PER performance indicators, or there is some correlation between data packets, the mapping relationship information can also be referred to as dependency relationship information.

[0076] (7) packets belonging to a specific service or satisfying a specific service period;

[0077] (8) packets satisfying a specific size;

[0078] (9) packets satisfying a specific PDB;

[0079] (10) specific PDU (Protocol Data Unit) identifier;

[0080] (11) specific SDU (Service Data Unit) identifier;

[0081] (12) specific TB (Transport Block) identifier.

[0082] In a possible implementation, the preset condition includes:

[0083] (1) a target transport unit reaches a target protocol layer, the target transport unit including at least one of a data frame, a data slice, an Application Data Unit (ADU) and an Internet Protocol (IP) packet, the target protocol layer including at least one of an application layer, an IP layer, a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer and a physical layer;

[0084] (2) the terminal identifies a target object, or the terminal generates an action or a control service corresponding to the target object, wherein the target object includes at least one of a target gesture, a target action, a target pose and a target object at a preset angle;

[0085] Further, the preset condition further includes any one of the following:

[0086] (1) the preset service of the terminal is mapped to a specific logical channel, preset service information changes, and the specific logical channel has preset service packets;

[0087] (2) the preset service of the terminal is mapped to a specific logical channel, the change value of the preset service information is greater than a preset threshold, and the specific logical channel has preset service packets.

[0088] In a possible implementation, the preset service information includes action information or control service information, and the action information or control service information includes at least one of a target change direction, a target movement speed, a target pose, a target pose change amount and a target action.

[0089] It should be noted that the preset service is not limited to the action control service, and can also include an XR interaction service, a basic layer service of adaptive transmission, an enhanced layer service of adaptive transmission, and a data transmission service of a video service.

[0090] Taking the preset service information as an example, the preset service information is pose information of an XR service:

[0091] The change of the preset service information can refer to a change direction or a movement trend of the pose, for example, left or right.

[0092] The change value of the preset service information can refer to: a change degree of the pose, for example, a speed of the UE, an average speed, a change amount of an instantaneous speed. For another example, the change degree of the pose can be measured by an Euclidean distance between space points or a two-dimensional displacement distance, and the like. In a 3DoF scenario, an angle ≥ Y, or, the Euclidean distance between a point a (x1, y1, z1) and a point b (x2, y2, z2) in a three-dimensional space If a 6DoF scenario is taken as an example, in addition to the above change in the three-dimensional space, a change in position information, such as a displacement distance, is also included.

[0093] It can be understood that the pose information can also be a combination of the above change trend and change degree, which will not be described here.

[0094] Optionally, the preset service information can be further classified, and different degrees (numbers) of SRS reporting can be triggered according to different classifications. How to classify or group the preset service information and the reporting content can be configured by the network.

[0095] In a possible implementation, a terminal performs an uplink signal sending related operation, including: the terminal sends an SRS and / or an SRS sending request on a target resource.

[0096] Further, the target resource satisfies any one of the following conditions:

[0097] (1) The target resource is a resource for sending a PUSCH, wherein the resource for sending the PUSCH is a resource for sending a grant-free PUSCH or a resource for sending a dynamically scheduled PUSCH.

[0098] At this time, the existing conditions include: (1) the target resource is a resource for sending a PUSCH, but since the sending of the SRS is triggered, the processing mode is to send the SRS using the target resource, and the target resource is not used to send the PUSCH; (2) the target resource is used to send the PUSCH, but since the sending of the SRS is triggered, the processing mode is to send the PUSCH and the SRS together on the target resource, that is, the target resource is multiplexed; (3) the PUSCH is a grant-free PUSCH or a dynamically scheduled PUSCH, and when the SRS or the SRS sending request is triggered, the processing mode is to send the SRS or the SRS sending request using the target resource, and the target resource is not used to send the PUSCH.

[0099] (2) The target resource is a first resource that does not overlap with a resource for sending a PUSCH; that is, the target resource is an independent resource that does not overlap with the resource for sending the PUSCH.

[0100] (3) The target resource is a Physical Random Access Channel (PRACH);

[0101] (4) The target resource is a Physical Uplink Control Channel (PUCCH).

[0102] In a possible implementation, the SRS transmission request is carried in a Media Access Control Element (MAC CE) or first Uplink Control Information (UCI).

[0103] In a possible implementation, the method further includes:

[0104] The terminal transmits a second UCI. In one specific implementation, when the terminal uses a grant-free PUSCH resource, the second UCI is a configured grant UCI (CG-UCI), and the second UCI includes at least one of the following:

[0105] (1) Indication information for indicating whether to transmit an SRS and / or an SRS transmission request; for example, 1 bit is used for indication, and '0' indicates that no transmission is performed, and '1' indicates that transmission is performed.

[0106] (2) Related information of an SRS configuration;

[0107] Further, before the step of performing an uplink signal transmission related operation by the terminal, the method further includes: obtaining, by the terminal, a correspondence between one or more grant-free resources and an SRS configuration.

[0108] Further, the related information of the SRS configuration includes:

[0109] One or more SRS resource identifiers, that is, one or more SRS Resource IDs are reported in the CG-UCI, and the SRS Resource ID is used to identify which SRS is transmitted.

[0110] Optionally, the related information of the SRS configuration can also include a first index, and the first index has a preconfigured correspondence with the SRS configuration; that is, the network side preconfigures a correspondence between an SRS configuration (group) and an index (index) for the UE, and the UE notifies the network side of the SRS configuration (group) transmitted by the UE by indicating the index in the CG-UCI.

[0111] Optionally, the information related to the SRS configuration can also include a first parameter, which is used for network side detection of SRS; that is, all parameters required by gNB for detecting SRS are contained in CG-UCI, and then the network side detects SRS at the corresponding position after receiving the corresponding information.

[0112] Optionally, the network pre-configures a correspondence between a preset service (or information) and a configured grant (CG) resource, for example, CG config 1 is used for transmission of type 1 preset service information, and CG config 2 is used for transmission of type 2 preset service information. When the preset service is transmitted through CG config 1, the transmission of SRS is not triggered; when the preset service is transmitted through CG config 2, the transmission of SRS is triggered.

[0113] The type 1 preset service information and the type 2 preset service information refer to classified preset service information.

[0114] In one possible implementation, the terminal performs an uplink signal transmission related operation, including at least one of the following:

[0115] The terminal triggers the transmission of SRS through a high layer or a physical layer;

[0116] The terminal triggers the transmission of an SRS transmission request through a high layer or a physical layer.

[0117] That is, the above process can be triggered by a high layer or a physical layer:

[0118] The high layer and the physical layer interact with each other to inform the physical layer to trigger the above process;

[0119] Alternatively, the physical layer triggers the above process through high layer service related information;

[0120] The high layer includes, for example, a MAC, RLC or PDCP layer.

[0121] The technical solutions of the present application will be described below in combination with specific embodiments:

[0122] Embodiment 1:

[0123] Referring to Figure 3a, the network configures downlink SPS for the transmission of downlink video service data, and configures uplink CG resources for the transmission of uplink pose service. The period of the uplink CG resource is shorter than that of the downlink SPS. When the IP packet of the pose service arrives, the UE detects that the change degree of the pose information exceeds a certain range, and indicates the transmission of SRS through CG-UCI (when the change degree of the pose is less than a certain value, SRS reporting is not triggered). SRS uses resources independent of PUSCH for transmission, and gNB detects SRS at the corresponding position according to the indication of CG-UCI.

[0124] Embodiment 2:

[0126] When the user pose changes, the UE carries SRS when sending CG-PUSCH, that is, SRS and CG-PUSCH are multiplexed on the CG-PUSCH resource for transmission.
