Technical field
[0001]
The embodiments of the present invention relate to the field of communication technologies, and in particular to a method for monitoring and sending downlink signals, a method and a device for parameter configuration.
Background technique
[0002]
In the high-frequency communication scenario, the communication link is susceptible to physical conditions, such as weather, obstacles, changes in direction and angle, and other factors, resulting in transmission failure in the original beam direction. The beam failure recovery technology is mainly aimed at this scenario, using the measurement results of beam power in different directions to quickly locate a new and reliable beam direction, thereby completing the rapid recovery of the link.
[0003]
The beam failure recovery (BFR, Beam Failure Recovery) technology is not only very effective in single carrier scenarios, but also can play an important role in multi-carrier scenarios. In a multi-carrier scenario, a terminal device can be connected to one network device (for example, a base station) or multiple network devices. When different carriers of a terminal device are connected to network devices in different directions at the same time, because the spatial directions are relatively independent, at a certain moment, only part of the connections on the different carriers may have beam failure. At this time, the beam failure recovery technology must be optimized for this scenario; for example, the use of the carrier without beam failure for parameter measurement and data transmission, etc., so as to improve the robustness of the system.
[0004]

It should not be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention.

[0065]
The following describes the scenarios of the embodiments of the present invention through examples, but the present invention is not limited to this.
[0066]
FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present invention, which schematically illustrates a case where a terminal device and a network device are taken as an example. As shown in FIG. 1, the communication system 100 may include a network device 101 and a terminal device 102. For the sake of simplicity, FIG. 1 only takes one terminal device and one network device as an example for description, but the embodiment of the present invention is not limited to this.

[0068]
Take beam failure recovery as an example. For example, when the conditions related to beam failure detection are met, the corresponding random access process will be triggered, and the beam failure recovery response is the corresponding random access response (RAR, Random Access Response); that is, The beam failure recovery process can be understood as: a random access procedure for beam failure recovery (random access procedure for beam failure recovery). When the network device configures multiple carriers for the terminal device, the terminal device may not be able to determine the quasi-positioning synchronization parameters of the antenna port of the receiving beam failure recovery response.
[0069]
2 is a schematic diagram of the same serving cell that initiates the beam failure recovery process and the serving cell that receives the beam failure recovery response.

[0071]
When the spatial locations of the base stations corresponding to the serving cell 1 and the serving cell 2 are different, the quasi positioning synchronization parameters of the antenna ports of the terminal devices corresponding to FIG. 2 and FIG. 3 for receiving the random access response should be different. However, according to the current standard, the terminal device does not have the ability to distinguish between the scenarios corresponding to Figure 2 and Figure 3. Therefore, the terminal device will still use the same antenna port quasi-positioning synchronization parameter to cope with the two scenarios in FIG. 2 and FIG. 3, resulting in the inability to accurately receive the random access response.
[0072]
The embodiments of the present invention are described below. It is worth noting that the embodiment of the present invention takes beam failure recovery response or random access response as an example for description, but the present invention is not limited to this, and can also be applied to other similar downlink signals.

[0082]

[0083]
Step 501: The terminal device receives the monitoring parameter sent by the network device.
[0084]
For example, the monitoring parameters may include the transmission configuration indicator (TCI, Transmission Configuration Indicator) state in the control resource set (CORESET), the beam failure recovery configuration, etc.; they can be configured through RRC messages. For these monitoring parameters, you can refer to related technologies, which will not be repeated here.
[0085]
Step 502: The terminal device sends a beam failure recovery request to the network device.
[0086]
For example, when the beam failure recovery process is initiated by the higher layer (for example, the MAC layer) of the terminal device, the higher layer provides the index q new of the reference signal related to the beam failure response corresponding to the beam failure recovery process . Q new new is high in the list of candidate beam reference signal configured by higher layers (e.g., candidateBeamRSList) selected reference signal index, and Q new new serving cell associated or Q new new cells corresponding to the random access procedure is occurring c 1 (the first cell).

[0088]
For example, if the primary serving cell (PCell) of the terminal device is c 2 (the second cell), the terminal device can determine the quasi-positioning synchronization parameters of the antenna port according to the first cell and/or the second cell; for details, please refer to the following Examples.
[0089]
In step 504, the terminal device uses the antenna port quasi positioning synchronization parameter to receive a beam failure recovery response.
[0090]
It is worth noting that the above Figures 4 or 5 only schematically illustrate the embodiments of the present invention, but the present invention is not limited thereto. For example, the order of execution among the various steps can be appropriately adjusted, and some other steps can be added or some steps can be reduced. Those skilled in the art can make appropriate modifications based on the foregoing content, and are not limited to the description of the foregoing FIG. 4 or 5.
[0091]
The following uses multiple implementation manners as an example to describe how to determine the antenna port quasi positioning synchronization parameter.
[0092]
In one embodiment, when the first cell and the second cell are the same, the terminal device monitors the quasi positioning synchronization parameters of the antenna port associated with the reference signal index associated with the first cell The downlink signal.
[0093]
For example, after the beam failure recovery process is initiated by the higher layer, the higher layer provides the reference signal index q new related to the beam failure response corresponding to the beam failure recovery process . Wherein, Q new new is a list of candidate reference signal level at the top beam configuration (e.g., candidateBeamRSList) selected reference signal index, and Q new new serving cell associated or Q new new corresponding random access procedure occurred The cell is c 1 . The serving cell where the terminal device monitors the downlink signal is c 2 . If c 1 and c 2 are the same, or c 1 is a SpCell (for example, when the serving cell that monitors the downlink signal can only be SpCell), the terminal device monitors the downlink signal according to the antenna port quasi positioning synchronization parameter associated with q new . Wherein, the antenna port quasi-positioning synchronization parameter associated with q new may be understood as the reference signal corresponding to the candidate beam reference signal list indicated by q new .
[0094]
In addition, the serving cell associated with q new may be equivalent to the corresponding serving cell that initiates the beam failure procedure. The serving cell associated with q new may also be equivalent to the cell that sends the corresponding beam failure report (for example, PRACH, MAC CE).
[0095]
In another embodiment, the terminal device is in a situation where the first cell and the second cell are different, and the control resource set (CORESET) for monitoring the downlink signal does not have a corresponding activated TCI state And monitor the downlink signal according to the antenna port quasi-positioning synchronization parameter associated with the reference signal index associated with the first cell.
[0096]
For example, after the beam failure recovery process is initiated by the higher layer, the higher layer provides the index q new of the reference signal related to the beam failure response corresponding to the beam failure recovery process . Wherein, Q new new is a list of candidate reference signal level at the top beam configuration (e.g., candidateBeamRSList) selected reference signal index, and Q new new serving cell associated or Q new new corresponding random access procedure occurred The cell is c 1 . The serving cell where the terminal device monitors the downlink signal is c 2 . If c 1 and c 2 are different, or when c 1 is a non-SpCell (for example, when the serving cell that monitors the downlink signal can only be SpCell), and the TCI state in which the CORESET corresponding to the downlink signal is not activated, The terminal device monitors the downlink signal according to the quasi-positioning synchronization parameter of the antenna port associated with q new . Wherein, the antenna port quasi-positioning synchronization parameter associated with q new may be understood as the reference signal corresponding to the candidate beam reference signal list indicated by q new .
[0097]
In addition, the serving cell associated with q new may be equivalent to the corresponding serving cell that initiates the beam failure procedure. The serving cell associated with q new may also be equivalent to the cell that sends the corresponding beam failure report (for example, PRACH, MAC CE).
[0098]
In another embodiment, when the first cell and the second cell are different, and high-level configuration parameters are not configured or configured in the first state, the terminal device is The antenna port quasi positioning synchronization parameter associated with the reference signal index associated with the cell monitors the downlink signal.
[0099]
The high-level configuration parameters can be configured by a network device and used to obtain the quasi-positioning synchronization parameters; the high-level configuration parameters can be configured as the first state (for example, disable) or the second state (for example, enable Can enable).
[0100]
In this embodiment, the above-mentioned high-level configuration information may be, for example, SCell_SpCell_Diff_QCL_Flag.
[0101]
For example, after the beam failure recovery process is initiated by the higher layer, the higher layer provides the index q new of the reference signal related to the beam failure response corresponding to the beam failure recovery process . Wherein, Q new new is arranged candidateBeamRSList reference signal index information selected by the rise in the level, and Q new new serving cell associated or Q new new cells corresponding to the random access procedure is occurring C . 1 . The serving cell where the terminal device monitors the downlink signal is c 2 . If c 1 is different from c 2 , or c 1 is a non-SpCell (for example, when the serving cell that monitors the downlink signal can only be SpCell), and when the high-level configuration information is configured to be disabled (for example, SCell_SpCell_Diff_QCL_Flag=disable) At this time, the terminal device monitors the downlink signal according to the quasi-positioning synchronization parameter of the antenna port associated with q new . Wherein, the antenna port quasi positioning synchronization parameter associated with q new may be understood as a reference signal corresponding to the candidate beam reference signal list indicated by q new .
[0102]
In the present embodiment, when the high-level configuration information configured to enable the terminal equipment listens C 2 when BFR in response to a serving cell and other than C2 BFR other serving cell response, can be synchronized according to the same port quasi positioning antenna Parameter monitoring BFR response. Or, in a scenario where the BFR response is only monitored in the SpCell, when the high-level configuration information is configured to be disabled, the terminal device monitors the non-SpCell BFR response and the SpCell BFR response according to the same antenna port quasi positioning synchronization parameter.
[0103]
In addition, the serving cell associated with q new may be equivalent to the corresponding serving cell that initiates the beam failure procedure. The serving cell associated with q new may also be equivalent to the cell that sends the corresponding beam failure report (for example, PRACH, MAC CE).
[0104]
In another embodiment, when the first cell and the second cell are not the same, the terminal device monitors the downlink signal according to an antenna port quasi positioning synchronization parameter associated with the second cell.
[0105]
For example, after the beam failure recovery process is initiated by the higher layer, the higher layer provides the index q new of the reference signal related to the beam failure response corresponding to the beam failure recovery process . Among them, q new is the reference signal index selected by the higher layer in the high-level configuration information candidateBeamRSList, and the associated serving cell where q new is located, or the cell where the random access process corresponding to q new occurs is c 1 . The serving cell where the terminal device monitors the downlink signal is c 2 . If c 1 and c 2 are not the same, or c 1 is a non-SpCell (for example, when the serving cell that monitors the downlink signal can only be SpCell), the terminal device can quasi-position according to the antenna port of the serving cell c 2 (or SpCell) The synchronization parameter monitors the downlink signal.
[0106]
In this embodiment, the antenna port quasi-positioning synchronization parameter associated with the second cell may include at least one of the following:
[0107]
The quasi positioning synchronization parameter of the antenna port of the reference signal associated with the physical random access channel (PRACH) transmission corresponding to the downlink signal;
[0108]
When the interval between the downlink control information (DCI) and the physical downlink shared channel (PDSCH) scheduled by the DCI is less than a certain threshold, the quasi-positioning synchronization parameter of the antenna port used to receive the PDSCH; for example, the parameter It can be: QCL parameter(s) used for PDCCH quasi co-location indication of the lowest CORESET-ID in the latest slot in which one or more CORESETs within the active BWP of the serving cell are configured for the UE;
[0109]
Monitoring the quasi positioning synchronization parameter of the antenna port corresponding to the activated TCI state corresponding to the control resource set (CORESET) of the downlink signal;
[0110]
If the CORESET monitoring the downlink signal does not have a corresponding activated TCI state, it means that the most recent time slot in the one or more control resource sets configured for the terminal device in the active part bandwidth (BWP, Bandwidth Part) of the cell has The parameter (for example, QCL parameter(s) used for PDCCH quasi co-location indication of the lowest CORESET-ID in the latest slot in which one) of the lowest control resource set number for the physical downlink control channel (PDCCH) quasi-location synchronization indication or more CORESETs within the active BWP of the serving cell are configured for the UE);
[0111]
