Description

Transmission and reception method, device and communication system for transmitting configuration indication Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a transmission and reception method, apparatus, and communication system for a Transmission Configuration Indication (TCI).

Background technique

Large-scale multiple-input multiple-output (MIMO) technology is a key technology in new wireless (NR, New radio) systems, including studies below 6 GHz and above 6 GHz. As the frequency band increases, the fading and loss generated in the transmission will increase accordingly. Beamforming technology becomes a key technology in large-scale MIMO technology because it can effectively compensate for fading.

In the study of massive MIMO technology, in order to improve the reliability of transmission, beamforming techniques that simultaneously transmit multiple beams for physical channels (eg, broadcast channels, data channels, control channels, etc.) are allowed. Since network devices (such as base stations) and user equipments (UE, User Equipment) have the capability of transmitting and receiving multiple beams, beam management can be obtained by beam management, for example, beam scanning by the receiving end and the transmitting end. Optimal transmit and receive beam combination.

For example, the current Third Generation Partnership Project ^{(3GPP, 3 rd Generation Partnership Project} ) NR downlink beam management system can include the following three processes.

Process 1 (P1): The base station transmits a plurality of different beams; the UE measures the beams and selects a better-quality transmitter beam.

Process 2 (P2): The base station transmits a plurality of different beams. Compared with P1, the P2 phase beams are more fine (narrow), which may be a smaller set of P1 phase beams; the UE measures these beams and selects them. A better quality transmitter beam.

Process 3 (P3): The base station transmits multiple identical beams; the UE uses different receiving end beams to receive, thereby selecting a better quality receiving end beam.

It can be seen that, through the three processes of beam management, the UE can obtain the quality of the beam pair (BPL, Beam Pair Link) of multiple different beams at the transmitting end and multiple different beam combinations at the receiving end. The current NR system supports the reporting of the beam quality of the multiple transmitters by the UE, for example, reporting the better-quality beam number and the corresponding reference signal received power (RSRP, Reference Signal Received Power) to the base station. Beam number, for example The resource number of the channel state information reference signal (CSI-RS, Channel State Information Reference Signal) and/or the time number of the synchronization signal (SS, Synchronization Signal) block may be used.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of the present invention.

Summary of the invention

The inventors have found that after the base station obtains the better quality beam reported by the UE, these beams can be used in the transmission of physical channels (for example, broadcast channels, data channels, control channels, etc.) to obtain higher transmission quality. At the same time, the NR supports the base station to indicate the transmitting end beam to the UE, so that the UE can decide which receiving end beam to use for the aligned receiving.

However, there is currently no solution for how to send and receive beam indications or how to update the beam indication status. It should be noted that the beam indication in the embodiment of the present invention may be referred to as a Quasi-Co-Location (QCL) indication, or may also be used as a parameter or partial configuration of a Transmission Configuration Indication (TCI).

Example 1

An embodiment of the present invention provides a method for receiving a transmission configuration indication, which is applied to a user equipment side.

2 is a schematic diagram of a method for receiving a transmission configuration indication according to an embodiment of the present invention, which is performed from a user equipment side. Description. As shown in FIG. 2, the method includes:

Step 201: The user equipment receives a command sent by the network device to trigger the user equipment to perform a transmission configuration indication status update;

Step 202: The user equipment feeds back, to the network device, status information of the updated one or more transmission configuration indications, and/or indication information indicating whether the status of the one or more transmission configuration indications changes. Feedback to network devices.

In this embodiment, the user equipment may further receive configuration information of multiple transmission configuration indications sent by the network device, and/or receive update information of one or more transmission configuration indications sent by the network device.

For example, the network device can notify the user equipment of the M candidate TCI states and/or update one or more candidate TCI states to the user equipment. For example, the network device may update the current TCI state for the previous TCI state, for example, using RRC signaling or MAC CE or DCI; or may indicate all M TCI states to the user equipment at intervals, for example, using RRC. Signaling.

In addition, regarding the specific content of the TCI, reference may be made to related technologies, and details are not described herein again.

In this embodiment, the update information indicated by the transmission configuration may include one or more of the following: the number of states indicated by the transmission configuration, and the reference signal identification (ID) information corresponding to the sender beam of the increase or decrease. The number of the transmission configuration indication state corresponding to the transmitting end beam, the set of the reference signal ID information corresponding to the increasing or decreasing of the transmitting end beam, and the set of the transmission configuration indication state corresponding to the increasing or decreasing transmitting beam of the transmitting end beam, and the increase or decrease Or the reduced set number of the reference signal identification information corresponding to the sender beam.

However, the invention is not limited thereto, and for example, other information may also be included. The reference signal ID information generally corresponds to the number information of the beam, such as the ID of the CSI-RS, the number of the CSI-RS resource indication (CRI), or the number of the SSB (SS Block).

For example, when performing the TCI status update, the network device may only include the reference signal ID information corresponding to the added or subtracted transmit end beam, and does not include its corresponding TCI status number; or it may include both added or subtracted The TCI status number that is dropped also includes the reference signal ID information corresponding to the added or subtracted transmit end beam; or, in order to reduce the misinterpretation between the network device and the user equipment, when updating the TCI status, each time Only one transmit beam is added or subtracted.

In this embodiment, the status information indicated by the transmission configuration includes one or more of the following information:

The number of states indicated by the transmission configuration, the number of the transmission configuration indication state, the reference signal ID information corresponding to the transmitter beam, the reference signal ID information corresponding to the increased or decreased transmit beam, and the increased or decreased transmission The transmission configuration corresponding to the sending end beam indicates the number of the status, the set of the reference signal ID information corresponding to the increasing or decreasing of the transmitting end beam, the set of the transmission configuration indication state corresponding to the increasing or decreasing transmitting beam, and the increasing or decreasing transmitting end The set number of the reference signal identification information corresponding to the beam.

In this embodiment, the network device may explicitly or implicitly send a command for triggering the user equipment to perform a transmission configuration indication status update. The command may be trigger information included in the DCI, or other trigger information; further explanation will be given below.

FIG. 3 is a schematic diagram of a method for transmitting and receiving a transmission configuration indication according to an embodiment of the present invention, which is described from a user equipment side and a network equipment side. As shown in FIG. 3, the method may include:

Step 301: The network device sends initial configuration information of multiple transmission configuration indications, and/or sends update information of one or more transmission configuration indications.

In this embodiment, the network device may implicitly trigger the user equipment to perform a transmission configuration indication status update. For example, whenever the network device notifies or updates the TCI status, the user equipment is implicitly triggered to report whether to update the current TCI status. However, the present invention is not limited thereto, and the user equipment may be explicitly triggered to perform the transmission configuration indication status update as described in the following embodiments.

Step 302: The user equipment updates one or more transmission configuration indications according to the configuration information and/or the update information and a current status of the pre-stored multiple transmission configuration indications.

In this embodiment, the user equipment may add and/or merge the multiple transmission configuration indications according to the configuration information and/or the update information, the current status of the multiple transmission configuration indications pre-stored, and the result of the beam measurement. status.

For example, after the beam management process (P1, P2, and P3), the user equipment can obtain the association information of the better-quality transceiver beam pairs, and can report the better-quality transmitter beam numbers and/or corresponding beams by beam reporting. The RSRP is reported to the base station. Although the base station can know the transmitter beam number of the better quality, it does not know the corresponding receiver beam number. From the perspective of the user equipment, the transmitter beam corresponding to one or more states sent by the base station may correspond to the same receiver beam, and therefore, the multiple TCIs are indicated from the perspective of indicating the user equipment to determine the receiver beam. The status is merging.

Similarly, the status of TCI can also be increased. In addition, one or more quality transmitter beams may be added to a current TCI state, or one or more poor quality transmitter beams may be removed from the corresponding TCI state.

For example, the current state of the TCI of the user equipment may include six. Receiving updates sent by network devices After the information, the user equipment may merge some of the states; thereby updating the status of the TCI to 4; or after receiving the update information sent by the network device, the user equipment may add some new status; thereby updating the status of the TCI to 8; or after receiving the update information sent by the network device, the user equipment adds one or more sender beams to the current TCI state; or after receiving the update information sent by the network device, the user equipment One or more transmit end beams are removed from the corresponding TCI state.

Step 303: The user equipment feeds back the updated TCI status information to the network device.

For example, the user equipment sends the number of the beam number (eg, CSI-RS ID, SSB ID) and the recommended transmission configuration indication status that are desired to be added to the network device. The number of the beam that is desired to be lost (eg, CSI-RS ID, SSB ID) and the number of the transmission configuration indication status of the beam configuration configured by the network device may also be sent to the network device. The update information can be sent using the uplink control information.

In this embodiment, after the user equipment updates the multiple transmission configuration indications, the status information of the updated multiple TCIs may be directly fed back to the network device; the network device may also be based on the status information. Multiple transport configuration indications are updated to indicate that the update of the user device is in effect. Thereby, the network device and the user equipment can agree on the state of the transmission configuration indication, and can accurately perform beam-based information transmission.

In this embodiment, the network device may also use the trigger information to trigger the user equipment to report and update the status information of the TCI.

4 is another schematic diagram of a method for transmitting and receiving a transmission configuration indication according to an embodiment of the present invention, which is described from the user equipment side and the network equipment side; the same content as that of FIG. 3 is not described again. As shown in FIG. 4, the method may include:

Step 401: The network device sends configuration information of multiple transmission configuration indications, and/or sends update information of one or more transmission configuration indications.

For example, when performing the TCI status update, the network device may only include the added or subtracted transmit end beam number, and does not include its corresponding TCI status number; or it may include both the added or subtracted TCI status number. It also includes the added or subtracted transmit beam number; or, in order to reduce the misinterpretation between the network device and the user equipment, when updating the TCI state, it is also possible to add or subtract only one transmit end beam at a time. set.

Step 402: The network device sends first trigger information for triggering the user equipment to report whether to update multiple TCIs; that is, the network device triggers a command for the user equipment to update the transmission configuration indication.

In an embodiment, the first trigger information may be explicitly carried by DCI. For example, use A control area in the DCI directly triggers the user equipment to report whether to update the current TCI status.

For example, a bit of a DCI format uses a bit to trigger the user equipment to report whether to update the current TCI status. When the bit is set to 1, it indicates that the network device triggers the user equipment to report whether to update the current TCI status. When the bit is set to 0, it indicates that the network device does not trigger the user equipment to report whether to update the current TCI status.

In another embodiment, the first trigger information may be implicitly carried by the update information.

For example, whenever the network device notifies or updates the TCI status (ie, when step 401 is executed), the user equipment is implicitly triggered to report whether to update the current TCI status. In this case, step 402 can be omitted.

In another embodiment, the first trigger information may be jointly encoded with control signaling to be carried. For example, it can be jointly coded with control signaling of other DCI control domains.

For example, the trigger information of the aperiodic CSI-RS transmission or the aperiodic beam reporting may be jointly coded. For example, when the encoding is performed in combination with the triggering information of the non-periodic beam reporting, the state 00 may indicate that the user equipment is triggered to report whether to update the current TCI state; the state 01 may indicate an aperiodic beam reporting mode; the state 10 may indicate another An aperiodic beam reporting mode.

In this embodiment, different modes may indicate that the parameters reported by the beam are different. When coding with other control signaling, the total number of bits may be 1, 2, 3, etc., depending on the number of states of other control signaling, and is used to trigger the UE to report whether the current TCI state is updated. There can be only one; there can be more than one.

In addition, the above methods can be used in conjunction with RRC signaling, that is, the switch of the trigger function is configured using RRC signaling. For example, when the RRC signaling configures the trigger function to be “on”, the above methods take effect; when the RRC signaling configures the trigger function to “off”, the above methods do not take effect.

In another embodiment, the network device may also configure the user equipment to periodically report whether to update the current TCI status. That is, the first trigger information is a periodic report configuration configured by RRC signaling; however, the present invention is not limited thereto.

Step 403: The user equipment determines whether a status of one or more transmission configuration indications changes.

Step 404: The user equipment sends, to the network device, indication information indicating whether the status of the one or more transmission configuration indications changes.

In this embodiment, the indication information may include one or more of the following information: indicating the transmission configuration Information indicating a change in the number of bits of the indicated number of states, information indicating that the number of bits of the state of the transmission configuration indication has not changed, information indicating that the state of the transmission configuration indication is increased, indicating the transmission configuration indication Status merged information; however, the invention is not limited thereto.

For example, suppose the number of TCI states after the status update is N _af , and if [log ₂ N _af ]>[log ₂ M], the UE reports “00”, which occurs when the gNB updates the TCI status, and is updated. The status cannot be merged with the current other TCI status. If [log ₂ N _af ]<[log ₂ M], the UE reports "01". If [log ₂ N _af ]=[log ₂ M], the UE reports "10".

In the present embodiment, the states "00", "01", and "10" are for illustrative purposes only, but are not limited thereto.

In this embodiment, in the case that the number of bits indicating the number of states of the plurality of transmission configuration indications does not change, the user equipment may not update, that is, the TCI state information remains in the original state, and the network device is temporarily not fed back. Status information of the TCI.

For example, the current state of the TCI of the user equipment may include 6 (represented by 3 bits); after receiving the update information sent by the network device, the user equipment may add some new status; thereby updating the status of the TCI to 8 ( Still using 3 bits). Alternatively, after receiving the update information sent by the network device, the user equipment may merge some states; thereby updating the state of the TCI to 5 (still using 3 bits). Then, the number of bits of the number of states of the multiple TCIs does not change, and the user equipment can no longer feed back the state information of the TCI to the network device, and the TCI state information of the user equipment side remains in the original state, that is, no update is performed.

Thereby, the network device and the user equipment can maintain the same state of the transmission configuration indication, and can accurately perform beam-based information transmission.

In this embodiment, the network device may also use the trigger information to trigger the user equipment to report the updated TCI status information. In addition, updating the network transmission configuration indications by the network device may be completed by using RRC signaling or MAC CE.

5 is another schematic diagram of a method for transmitting and receiving a transmission configuration indication according to an embodiment of the present invention, which is described from the user equipment side and the network equipment side; the same contents as those in FIGS. 3 and 4 are not described again. As shown in FIG. 5, the method may include:

Step 501: The network device sends configuration information of multiple transmission configuration indications, and/or sends update information of one or more transmission configuration indications.

Step 502: The network device sends first trigger information used to trigger the user equipment to report whether to update multiple TCIs.

Step 503: The user equipment determines whether a status of the one or more transmission configuration indications changes.

Step 504: The user equipment sends, to the network device, indication information indicating whether the status of the one or more transmission configuration indications changes.

For example, suppose that the number of TCI states after the status update is N _af , and if [log ₂ N _af ]≠[log ₂ M], the UE reports “1”, that is, increasing the number of TCI states and reducing the number of TCI states are reported in the report. The same state is indicated. If [log ₂ N _af ]=[log ₂ M], the UE reports "0".

For example, suppose that the number of TCI states after the status update is N _af , and if [ log ₂ N _af ] ≤ [log ₂ M] or N _af ≤ M, the UE reports "1", that is, the number of TCI states can be merged. Otherwise, the UE reports "0".

It should be noted that the foregoing only exemplifies the content of the indication information and the timing of the transmission, but the present invention is not limited thereto, and the specific content or form may be determined according to actual needs.

Step 505: The user equipment updates one or more transmission configuration indications according to the configuration information and/or the update information and a current status of the pre-stored multiple transmission configuration indications.

In this embodiment, the user equipment may update according to one or more of the configuration information, the update information, and the result of the beam measurement, and the current status of the pre-stored multiple transmission configuration indications (for example, may include: adding And/or merge and/or subtract and/or split, ie may be one or more of the four operations) states of the plurality of transmission configuration indications. In addition, reference signal identification information corresponding to the one or more transmit end beams may also be added and/or combined and/or subtracted and/or split.

In this embodiment, in a case where the number of bits indicating the number of states of the plurality of transmission configuration indications changes, the user equipment may feed back the state information of the TCI to the network device.

For example, the current state of the TCI of the user equipment may include 6 (using 3 bit representation); after receiving the update information sent by the network device, the user equipment may add some new status; thereby updating the status of the TCI to 9 ( Use 4 bits to indicate). Alternatively, after receiving the update information sent by the network device, the user equipment may merge some states; thereby updating the state of the TCI to 4 (using 2 bits). Then, the number of bits of the number of states of the multiple TCIs changes, and the user equipment can feed back the state information of the TCI to the network device.

Step 506: The network device sends the multiple transmission configuration indications that are used to trigger the user equipment to report the update. Second trigger information;

For example, if the UE reports the status of "00" or "01", the network device further triggers the UE to report the updated TCI status information. Alternatively, if the reporting of the UE is "0" or "1" in step 504, and the status reported by the UE is "1", the network device further triggers the UE to report the updated TCI status.

The state used in the triggering may be one or more. For example, one state may be used to indicate the TCI state that triggers the UE to report the update; or multiple states may be used to indicate multiple reporting forms of the trigger.

In this embodiment, the second trigger information may be explicitly carried by the DCI, or may be carried by jointly coding with the trigger information reported by the beam aperiodically. For example, the state “0” is used to trigger the beam number and the RSRP report, and the state “1” is used to trigger the TCI status update report. Or when a plurality of states are reported on the aperiodic beam, the 2 bits of the control area may be used, and the 3 bits are set to set the TCI state for triggering the UE to report the update and the aperiodic beam reporting of the UE to be jointly coded, and the UE is reported to be updated. The TCI state occupies one or more of these states.

Alternatively, the second trigger information may also be configured to be sent periodically.

Step 507: The user equipment feeds back the status information of the updated transmission configuration indication to the network device.
