[0002] The current power margin reporting mechanism is mainly that, when the terminal device receives an uplink authorization indication, for each cell to which the terminal device is connected, if the current time slot of the terminal device in the cell is an uplink time slot, the actual power margin is reported; if the current time slot of the terminal device in the cell is a downlink time slot, the virtual power margin is reported.

[0003] In the above scheme, the virtual power margin reported by the terminal device is limited, that is, when the virtual power margin is greater than the preset margin threshold, only the margin threshold is reported, resulting in insufficient resource blocks scheduled by the network device based on the power margin reported by the terminal device, affecting the transmission rate of the terminal device.

[0039] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0041] The current power margin reporting mechanism is mainly that, when the terminal device receives an uplink authorization indication, for each cell to which the terminal device is connected, if the current time slot of the terminal device in the cell is an uplink time slot, the actual power margin is reported; if the current time slot of the terminal device in the cell is a downlink time slot, the virtual power margin is reported.

[0042] In the above scheme, the virtual power margin reported by the terminal device is limited, that is, when the virtual power margin is greater than the preset margin threshold, only the margin threshold is reported, resulting in insufficient resource blocks scheduled by the network device based on the power margin reported by the terminal device, affecting the transmission rate of the terminal device.

[0043] Figure 1 The present invention is a flowchart of a method for reporting power headroom according to an embodiment of the present invention. It should be noted that the method for reporting power headroom according to the present embodiment can be applied to a device for reporting power headroom, which can be configured in an electronic device or chip so that the electronic device or chip can perform a function of reporting power headroom.

[0044] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0045] In addition, the power headroom reporting device may also be software in an electronic device, etc. The software may be, for example, power headroom reporting software, etc. In the following embodiments, the execution subject is an example of a terminal device for description.

[0046] like Figure 1 As shown, the method comprises the following steps:

[0047] Step 101, receiving an uplink authorization indication; the uplink authorization indication is sent to the terminal device by a network device corresponding to any cell to which the terminal device is connected.

[0048] In the embodiment of the present disclosure, the uplink authorization indication may be indication information sent by the network device to the terminal device, which is used to indicate which uplink resources the terminal device can use for uplink data transmission. For example, the uplink authorization indication may indicate the number of resource blocks (Resource Block) allocated by the network device to the terminal device.

[0049] It should be noted that the terminal device can be connected to multiple cells; for each cell, the uplink resources when the terminal device communicates with the network device corresponding to the cell can be indicated by the network device.

[0050] It should be noted that one network device can cover multiple cells. To facilitate the distinction, the uplink authorization indication can carry a cell identifier, and based on the cell identifier, it can be determined for which cell the uplink resources allocated by the network device are for. The network device covers multiple adjacent cells, and the multiple cells connected to the terminal device can be adjacent cells. Here, the multiple cells connected to the terminal device correspond to the same network device as an example for explanation.

[0051] In an embodiment of the present disclosure, when a terminal device receives an uplink authorization indication from a network device for one of the cells, it can report the power margins for multiple cells to enable the network device to allocate uplink resources for multiple cells based on the reported power margins for multiple cells.

[0052] Step 102, when the virtual power headroom of the terminal device exceeds the limit and the power headroom reporting mechanism is triggered, the target time slot is determined in combination with the time slot configurations of multiple cells to which the terminal device is connected; the target time slots of multiple cells are all uplink time slots.

[0053] In the embodiment of the present disclosure, the process of the terminal device determining whether the terminal device has a virtual power margin exceeding phenomenon may be, for example, determining the reference virtual power margin of the terminal device at each path loss value within a preset path loss range; and determining that the terminal device has a virtual power margin exceeding phenomenon when there is a reference virtual power margin greater than a preset margin threshold. For example, when the path loss value is less than 82dB, there may be a situation where the reference virtual power margin is greater than the preset margin threshold.

[0054] Among them, the reference virtual power margin of the terminal device based on the path loss value can be determined by combining the path loss value, the control parameters of the physical random access channel (PRACH) transmission power, etc.

[0055] It should be noted that if a certain reference virtual power margin is greater than the preset margin threshold, the virtual power margin calculated in combination with the actual path loss value may exceed the preset margin threshold, resulting in the terminal device only reporting the preset margin threshold when reporting, but not reporting the calculated virtual power margin, which may result in too few allocated uplink resources. Therefore, determining whether the terminal device has a virtual power margin exceeding the limit based on the reference power margin can improve the accuracy of determining the virtual power margin exceeding the limit.

[0056] In the embodiment of the present disclosure, when the target time slots of multiple cells are all uplink time slots, the terminal device can calculate and report the actual power margin for each of the multiple cells. Among them, since the actual power margin is calculated and determined based on the multiple allocated resource blocks, the calculated actual power margin is small; while the virtual power margin is calculated and determined based on the assumption that only a single resource block is allocated, the calculated virtual power margin is large. Therefore, it is much smaller than the virtual power margin, and the actual power margin does not exceed the preset margin threshold, which can avoid the situation where the subsequent uplink resources allocated are too few.

[0057] The target time slot may be the current time slot; or the target time slot may be a time slot after the current time slot.

[0058] The actual power headroom may be determined in combination with the uplink grant type, the configuration of a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) where the allocated resource blocks are located, the number of allocated resource blocks, and the like.

[0059] Step 103: determine the actual power headroom of the terminal equipment in multiple cells in the target time slot.

[0060] Step 104: reporting multiple actual power headrooms.

[0061] In an embodiment of the present disclosure, the terminal device may also perform the following process: when the target time slot is not determined by combining the time slot configurations of multiple cells to which the terminal device is connected, determine multiple power margins to be reported by combining the time slot configurations of multiple cells; and report the multiple power margins.

[0062] Specifically, the process of the terminal device determining multiple power margins to be reported in combination with the time slot configurations of multiple cells can be, for example, determining, for each cell to which the terminal device is connected, whether the current time slot of the terminal device in the cell is an uplink time slot according to the time slot configuration of the cell; when the current time slot is an uplink time slot, determining the actual power margin of the terminal device in the cell; or, when the current time slot is a downlink time slot, determining the virtual power margin of the terminal device in the cell; and determining the actual power margin or virtual power margin of the terminal devices in multiple cells in the current time slot as the power margin to be reported.

[0063] In the power margin reporting method of the disclosed embodiment, an uplink authorization indication is received; the uplink authorization indication is sent to the terminal device by the network device corresponding to any cell to which the terminal device is connected; when the virtual power margin of the terminal device exceeds the limit and the power margin reporting mechanism is triggered, the target time slot is determined in combination with the time slot configurations of the multiple cells to which the terminal device is connected; the target time slots of the multiple cells are all uplink time slots; the actual power margins of the terminal devices in the multiple cells are determined in the target time slot; the multiple actual power margins are reported; wherein, reporting the actual power margin of the terminal device in the target time slot can avoid reporting the virtual power margin of the terminal device in the target time slot, thereby being able to report accurate power margin, thereby ensuring that the network device schedules sufficient resource blocks for the terminal device, thereby improving the transmission rate of the terminal device.

[0064] Figure 2 This is a flow chart of a method for reporting power headroom according to another embodiment of the present disclosure. It should be noted that the method for reporting power headroom according to this embodiment can be applied to a device for reporting power headroom, which can be configured in an electronic device or chip so that the electronic device or chip can perform a function of reporting power headroom.

[0065] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, a controller in a vehicle, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0066] In addition, the power headroom reporting device may also be software in an electronic device, etc. The software may be, for example, power headroom reporting software, etc. In the following embodiments, the execution subject is an example of a terminal device for description.

[0067] like Figure 2 As shown, the method comprises the following steps:

[0068] Step 201, receiving an uplink authorization indication; the uplink authorization indication is sent to the terminal device by a network device corresponding to any cell to which the terminal device is connected.

[0069] Step 202, when the virtual power headroom of the terminal device exceeds the limit and the power headroom reporting mechanism is triggered, for each cell to which the terminal device is connected, determine whether each time slot of the cell is an uplink time slot according to the time slot configuration of the cell.

[0070] Step 203: for each of the time slots, if the time slots of multiple cells are all uplink time slots, determine the time slot as a candidate time slot.

[0071] In the disclosed embodiment, when the terminal device calculates the actual power margin, the resource blocks in the number of allocated resource blocks that need to be used are uplink resource blocks. When the time slot is a downlink time slot, the allocated resource blocks are downlink resource blocks, which are difficult to use for the calculation of the actual power margin, and only the calculation of the virtual power margin can be performed. Therefore, it is necessary to first determine whether each time slot of the cell is an uplink time slot, and then determine the time slot as a candidate time slot when the time slots of multiple cells are all uplink time slots.

[0072] It should be further explained that, in order to ensure that the actual power margin can be calculated later, when it is determined that the time slots of multiple cells are all uplink time slots, it is also necessary to determine whether resource blocks are allocated on the time slots of multiple cells. If resource blocks are allocated, uplink resource blocks are allocated to ensure that the actual power margin can be calculated later. Correspondingly, the process of the terminal device executing step 203 can be, for example, for each time slot in each time slot, when the time slots of multiple cells are all uplink time slots and are allocated resource blocks, determining the time slot as a candidate time slot.

[0073] Step 204: When the number of interval time slots between the candidate time slot and the current time slot of the terminal device is less than or equal to a first number threshold, determine the candidate time slot as a target time slot.

[0074] In order to ensure timely and rapid reporting of the power margin and avoid delays in reporting the power margin, the terminal device needs to ensure that the number of interval time slots between the target time slot and the current time slot is less than or equal to a first number threshold.

[0075] Specifically, the terminal device may also perform the following process: when the number of interval time slots between the candidate time slot and the current time slot of the terminal device is greater than a first number threshold, stop determining the candidate time slot as the target time slot.

[0076] In addition, when there are multiple target time slots, the number of interval time slots between each target time slot and the current time slot may be determined; the target time slot with the smallest number of interval time slots is retained, and other target time slots are ignored.

[0077] Step 205: determine the actual power headroom of the terminal equipment in multiple cells in the target time slot.

[0078] In an embodiment of the present disclosure, the process of the terminal device executing step 205 may, for example, be to determine, for each cell among multiple cells, the actual power margin of the terminal device in the cell at the target time slot based on the uplink authorization type at the target time slot, the number of allocated resource blocks, etc.

[0079] Step 206: reporting multiple actual power headrooms.

[0080] It should be noted that the detailed description of step 201, step 205 and step 206 can be found in Figure 1 Step 101, step 103 and step 104 in the illustrated embodiment will not be described in detail herein.

[0081] In the power headroom reporting method of the disclosed embodiment, an uplink authorization indication is received; the uplink authorization indication is sent to the terminal device by the network device corresponding to any cell to which the terminal device is connected; when the virtual power headroom of the terminal device exceeds the limit and the power headroom reporting mechanism is triggered, for each cell to which the terminal device is connected, it is determined whether each time slot of the cell is an uplink time slot according to the time slot configuration of the cell; for each time slot in each time slot, when the time slots of multiple cells are all uplink time slots, the time slot is determined as a candidate time slot; the interval between the candidate time slot and the current time slot of the terminal device is When the number of time slots is less than or equal to a first number threshold, the candidate time slot is determined as a target time slot; the actual power margin of the terminal devices in multiple cells is determined on the target time slot; and multiple actual power margins are reported; wherein, when the time slots of multiple cells are all uplink time slots, and the number of interval time slots between the time slot and the current time slot of the terminal device is less than or equal to the first number threshold, the time slot is determined as the target time slot, which can further ensure the reporting of the actual power margin on the target time slot, and further ensure that the network device schedules sufficient resource blocks for the terminal device, thereby improving the transmission rate of the terminal device.

[0082] Figure 3This is a flow chart of a method for reporting power headroom according to another embodiment of the present disclosure. It should be noted that the method for reporting power headroom according to this embodiment can be applied to a device for reporting power headroom, which can be configured in an electronic device or chip so that the electronic device or chip can perform a function of reporting power headroom.

[0083] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, a controller in a vehicle, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0084] In addition, the power headroom reporting device may also be software in an electronic device, etc. The software may be, for example, power headroom reporting software, etc. In the following embodiments, the execution subject is an example of a terminal device for description.

[0085] like Figure 3 As shown, the method comprises the following steps:

[0086] Step 301, receiving an uplink authorization indication; the uplink authorization indication is sent to the terminal device by a network device corresponding to any cell to which the terminal device is connected.

[0087] Step 302, when the virtual power headroom of the terminal device exceeds the limit and the power headroom reporting mechanism is triggered, the target time slot is determined in combination with the time slot configurations of multiple cells to which the terminal device is connected; the target time slots of multiple cells are all uplink time slots.

[0088] In the embodiment of the present disclosure, the terminal device may further perform the following process: when the terminal device does not have a virtual power headroom exceeding the limit, multiple power headrooms to be reported are determined in combination with the time slot configurations of multiple cells. Among the multiple power headrooms to be reported, some may be virtual power headrooms and some may be actual power headrooms.

[0089] In addition, when the terminal device does not trigger the power headroom reporting mechanism, the terminal device can stop performing power headroom reporting processing.

[0090] Step 303, when the target time slot is not determined by combining the time slot configurations of multiple cells to which the terminal device is connected, multiple actual power headrooms to be reported are determined by combining multiple historical power headrooms reported in each historical time slot.

[0091] In the embodiment of the present disclosure, the process of the terminal device executing step 303 may, for example, be: for each historical time slot, when the multiple historical power margins reported in the historical time slot are all historical actual power margins, determine the number of interval time slots between the historical time slot and the current time slot of the terminal device; when the number of interval time slots is less than or equal to the second number threshold, determine the multiple historical actual power margins reported in the historical time slot as the multiple actual power margins to be reported.

[0092] Among them, when the target time slot is not determined by combining the time slot configurations of multiple cells to which the terminal device is connected, it means that there may be a situation where virtual power margins are reported in each time slot after the current time slot, making it difficult to ensure the accuracy of the uplink resources subsequently allocated. However, by using each historical actual power margin in the historical time slots in which the historical actual power margins are reported as the actual power margin in the current time slot for reporting, the situation of reporting virtual power margins can be avoided, thereby ensuring the accuracy of the uplink resources subsequently allocated.

[0093] Step 304, when the target time slot has not been determined by combining the time slot configurations of multiple cells to which the terminal device is connected, and the multiple actual power margins to be reported have not been determined by combining the multiple historical power margins reported in each historical time slot, determine the multiple power margins to be reported by combining the time slot configurations of multiple cells.

[0094] The actual process of the terminal device determining the multiple power headrooms to be reported in combination with the time slot configurations of multiple cells can be referred to Figure 1 The description in the illustrated embodiment will not be described in detail here.

[0095] Step 305: reporting multiple power headrooms.

[0096] It should be noted that the resource scheduling comparison diagram of resource block scheduling based on actual power headroom and resource block scheduling based on virtual power headroom can be shown as follows: Figure 4 As shown. Figure 4 In the figure, PL-RB Alloc represents the relationship between path loss and scheduled resource blocks, that is, the resource blocks scheduled under various path loss conditions. PL represents path loss; RB represents resource blocks.

[0097] It should be noted that the detailed description of step 301 and step 302 can be found in Figure 1 Step 101 and step 102 in the illustrated embodiment will not be described in detail herein.

[0098] In the power headroom reporting method of the disclosed embodiment, an uplink authorization indication is received; the uplink authorization indication is sent to the terminal device by the network device corresponding to any cell to which the terminal device is connected; when the virtual power headroom of the terminal device exceeds the limit and the power headroom reporting mechanism is triggered, the target time slot is determined in combination with the time slot configurations of the multiple cells to which the terminal device is connected; the target time slots of the multiple cells are all uplink time slots; when the target time slot is not determined in combination with the time slot configurations of the multiple cells to which the terminal device is connected, the multiple actual power headrooms to be reported are determined in combination with the multiple historical power headrooms reported in each historical time slot; in combination with the time slot configurations of the multiple cells to which the terminal device is connected In the case where the target time slot has not been determined, and the multiple actual power margins to be reported have not been determined based on the multiple historical power margins reported in each historical time slot, the multiple power margins to be reported are determined in combination with the time slot configurations of multiple cells; the multiple power margins are reported; wherein, in the case where the target time slot has not been determined based on the time slot configurations of multiple cells to which the terminal device is connected, the multiple actual power margins to be reported are determined in combination with the multiple historical power margins reported in each historical time slot, which can further avoid the reporting of the virtual power margin, thereby being able to report the accurate power margin, thereby ensuring that the network device schedules sufficient resource blocks for the terminal device, thereby improving the transmission rate of the terminal device.

[0099] The following examples are used to illustrate this. Figure 5 The figure shows a schematic diagram of reporting power margin. Figure 5 In the process, the terminal device can perform the following steps. Step 501, determine whether the NW configuration (network configuration) will cause the better point virtual PH to exceed the reporting upper limit (i.e., whether the terminal device has a virtual power margin exceeding the limit); if so, execute step 502; if not, execute step 507. Step 502, determine whether there is a triggered PHR in the carrier aggregation scenario (i.e., triggering the power margin reporting mechanism). Step 503, if it is determined that an uplink authorization (i.e., an uplink authorization indication) is received, determine whether the configuration on the primary and secondary cell time slots is different; if the same, execute step 505; if different, execute step 504. Step 504, whether the sending time slot of the uplink authorization indication is an uplink time slot for the primary and secondary cells (each cell connected to the terminal device); if so, execute step 505; if not, execute step 503. Step 505, confirm the PH type of the primary and secondary cells (i.e., confirm the reporting of the actual power margin). Step 506, calculate the PH and report the PHR (calculate the actual power margin and perform reporting processing). Step 507, normal PHR process (ie, combining the time slot configurations of multiple cells, determining multiple power headrooms to be reported, and performing reporting processing).

[0100] Figure 6The flowchart of the power headroom receiving method of an embodiment of the present disclosure is as follows. It should be noted that the power headroom receiving method of the present embodiment can be applied to a power headroom receiving device, which can be configured in an electronic device or chip so that the electronic device or chip can perform the power headroom receiving function.

[0101] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0102] In addition, the power headroom receiving device may also be software in an electronic device, etc. The software may be, for example, power headroom receiving software, etc. In the following embodiments, the execution subject is a network device as an example for description.

[0103] like Figure 6 As shown, the method comprises the following steps:

[0104] Step 601, sending an uplink authorization indication to a terminal device; the network devices corresponding to the multiple cells connected to the terminal device include the network device that sends the uplink authorization indication.

[0105] In the embodiment of the present disclosure, the uplink authorization indication may be indication information sent by the network device to the terminal device, which is used to indicate which uplink resources the terminal device can use for uplink data transmission. For example, the uplink authorization indication may indicate the number of resource blocks (Resource Block) allocated by the network device to the terminal device.

[0106] It should be noted that one network device can cover multiple cells. To facilitate the distinction, the uplink authorization indication can carry a cell identifier, and based on the cell identifier, it can be determined for which cell the uplink resources allocated by the network device are for. The network device covers multiple adjacent cells, and the multiple cells connected to the terminal device can be adjacent cells. Here, the multiple cells connected to the terminal device correspond to the same network device as an example for explanation.

[0107] Step 602, receiving multiple actual power margins reported by the terminal device; the multiple actual power margins are the actual power margins to be reported on the target time slot; the target time slots of multiple cells are all uplink time slots; or, the multiple actual power margins are the actual power margins to be reported on the current time slot; the actual power margin to be reported on the current time slot is determined in combination with multiple historical power margins reported by the terminal device on each historical time slot.

[0108] In an embodiment of the present disclosure, in one example, the multiple actual power headrooms are actual power headrooms to be reported on target time slots; and the target time slots of the multiple cells are all uplink time slots.

[0109] The number of interval time slots between the target time slot and the current time slot for which the network device sends an uplink authorization indication may be less than or equal to the first number threshold.

[0110] In another example, multiple actual power margins are actual power margins to be reported in the current time slot; the actual power margin to be reported in the current time slot is determined by combining multiple historical power margins reported by terminal devices in each historical time slot.

[0111] The actual power headroom to be reported in the current time slot may specifically be a plurality of historical power headrooms reported by the terminal device in a certain historical time slot, wherein the number of interval time slots between the historical time slot and the current time slot may be less than or equal to the second number threshold.

[0112] In the embodiment of the present disclosure, after step 602, the network device may further perform the following process: performing resource block allocation processing in multiple cells for the terminal device in combination with multiple actual power headrooms reported by the terminal device.

[0113] In the method for receiving power margin in the embodiment of the present disclosure, an uplink authorization indication is sent to the terminal device; the network devices corresponding to the multiple cells connected to the terminal device include the network device that sends the uplink authorization indication; multiple actual power margins reported by the terminal device are received; the multiple actual power margins are the actual power margins to be reported on the target time slot; the target time slots of the multiple cells are all uplink time slots; or, the multiple actual power margins are the actual power margins to be reported on the current time slot; the actual power margin to be reported on the current time slot is determined in combination with the multiple historical power margins reported by the terminal device on each historical time slot; wherein, the reception of multiple actual power margins avoids the reception of virtual power margins, thereby being able to receive accurate power margins, thereby ensuring that the network device schedules sufficient resource blocks for the terminal device.
