FIG. 2 is a schematic flowchart of a communication method according to an exemplary embodiment. As shown in FIG. 2 , the communication method in this example is applicable to the network device side, and the network device may include a base station, a relay station, or a remote radio unit to access the network. equipment, which specifically includes the following processing steps:

Step 201: Send resource configuration information of the reference signal.

The reference signal is valid for all paging occasions (Paging Occasion, PO) or part of POs in a paging frame (Paging Frame, PF), that is, in the embodiment of the present disclosure, the reference signal configured by the network device Valid for all POs in the PF, or only for a certain PO or some POs. Specifically, the configuration of whether the PO is valid may be implemented by a network device, or the configuration of whether the PO in the PF is valid may be implemented by a network protocol.

In the embodiment of the present disclosure, the resource configuration information of the reference signal includes: time-frequency location information that carries the reference signal; and the time-frequency location is offset information relative to the starting point of the PF/PO. In order to simplify the configuration of the reference signal, the embodiment of the present disclosure uses the offset information of the reference signal relative to the starting point of the PF/PO to indicate, so that the UE can analyze the time-frequency position of the reference signal as soon as possible for monitoring to synchronize. In the embodiments of the present disclosure, although the starting point of PF/PO is recorded, for those skilled in the art, the starting point of PF/PO is only a reference time point, and may also be offset information of other reference time points, such as The start or end time point of other notification message frames, etc.

As an implementation manner, when the network device determines the time-frequency location information that bears the reference signal, it needs to receive the minimum offset between the reference signal supported by the UE and the PF/PO reported by the UE, that is, the network device needs to The UE reports the minimum offset between the reference signal supported by itself and the PF/PO to configure the time-frequency position of the reference signal, so that the UE can wake up at a suitable time to monitor the reference signal based on its own capabilities. Signal. Specifically, the network device determines, in the capability information of the UE, the minimum offset between the reference signal supported when demodulating the reference signal and the PF/PO; based on the minimum offset between the UE's reference signal and the PF/PO, determines offset value.

As an implementation manner, the network device determines the time-frequency position based on the minimum offset; wherein, the offset of the time-frequency position relative to the starting point of the PF/PO is greater than or equal to the minimum offset. That is, the network device needs to set the time-frequency location information of the reference signal according to the minimum offset between the reference signal supported by the UE and the PF/PO, so that the UE can monitor the reference signal within its own capability. , therefore, it is necessary to set the time-frequency position information of the reference signal according to the maximum value of the minimum offset between the reference signal reported by the UE and the PF/PO, so that the configured time-frequency position of the reference signal The offset between the information and the PF/PO is greater than the maximum value of the minimum offsets between the reference signal and the PF/PO supported by all UEs, so as to ensure that all UEs can normally monitor the reference signal in the DTX receiving mode .

As an implementation manner, the network device may obtain the minimum offset between the reference signal supported by the UE and the PF/PO based on the communication protocol. That is to say, when the minimum offset between the reference signal supported by the UE and the PF/PO is configured through the protocol, the network device can obtain the minimum offset between the reference signal supported by the UE and the PF/PO based on the communication protocol. Bias. Alternatively, the network device may receive the minimum offset between the reference signal supported by the UE and the PF/PO reported by the UE itself. At this time, the UE may realize the minimum offset between the reference signal supported by the UE and the PF/PO based on the uplink message. Biased reporting. Alternatively, the network device may also receive the minimum offset between the reference signal supported by the UE and the PF/PO sent by other network devices. The other network devices here may be related network devices on the core network side. For example, the core network may implement sending a notification of the minimum offset between the reference signal supported by the UE and the PF/PO to the access side network device.

As an implementation manner, the network device receives the capability information of the GAP between the reference signal supported by the UE and the PF/PO in the DRX scenario; or, receives the capability information for the GAP between the reference signal supported by the UE and the PF/PO .

At this time, the transmission period of the resource configuration information for transmitting the reference signal is implicitly indicated by a multiple of the paging frame period. As an example, the resource configuration information for sending the reference signal does not include information about the sending period, and the sending period and the paging frame density have a corresponding relationship:

oneT, halfT, quarterT, oneEighthT, and oneSixteenthT correspond to 10ms, 20ms, 40ms, 80ms, and 160ms of the transmission period, respectively. This is just an example of an implementation. Those skilled in the art should understand that other indicators can also be used to express corresponding indication information. As an example, inverted indication information can also be used to respectively indicate the above sending cycle, etc.

In the embodiment of the present disclosure, the sending reference signal includes at least one of the following: Tracking Reference Signal (TRS) and Cell Reference Signal (CRS).

In the embodiment of the present disclosure, when the base station does not deliver the resource configuration information of the TRS/CRS, the UE still performs synchronization based on monitoring the SSB according to the original synchronization method.

FIG. 3 is a schematic flowchart of a communication method according to an exemplary embodiment. As shown in FIG. 3 , the communication method in this example is applicable to the network device side, and the network device may include a base station, a relay station, or a remote radio unit to access the network. equipment, which specifically includes the following processing steps:

Step 301, when it is determined that the SSB configuration density exceeds the first set threshold, the TRS is not sent.

Here, when the configuration density of the SSB is relatively high, the UE can be completely synchronized based on the SSB without configuring the TRS.

Specifically, when the SSB configuration period and the paging frame interval are the same or smaller than the paging frame interval, and the PF configuration position is relatively close to the SSB, the TRS is not configured.

That is, when the SSB configuration period and the paging frame interval are the same or smaller than the paging frame interval, and the interval between the PF configuration position and the SSB is smaller, eg, smaller than the second set threshold, TRS does not need to be configured. The second set threshold here may be 5ms, 10ms or 15ms, and so on.

As an implementation manner, when the network device determines that the configuration period of the SSB is 5ms or 10ms, the resource configuration information of the TRS is not sent; or

When it is determined that the SSB configuration period is not greater than the paging frame interval and the interval between the PF and the SSB is less than the second set threshold, the resource configuration information of the TRS is not sent; the second set threshold here may be 5ms, 10ms or 15ms, etc.

As an implementation manner, when the network device determines that the paging search space pagingSearchSpace indication is 0 and the multiplexing mode is mode 2 or 3, the resource configuration information of the TRS is not sent.

As an implementation manner, when the network device determines that the paging search space pagingSearchSpace indication is 0, the multiplexing mode is mode 2 or 3, and the interval between the PF configuration location and the SSB is small, for example, it is smaller than the second set threshold. The resource configuration information of TRS is not sent below.

FIG. 4 is a schematic flowchart of a communication method according to an exemplary embodiment. As shown in FIG. 4 , the communication method in this example is applicable to a UE, and specifically includes the following processing steps:

Step 401: Send the minimum offset between the supported reference signal and the PF/PO to the network device.

According to the TRS/CRS configuration mode, the embodiments of the present disclosure perform TRS/CRS bias configuration for the PF and/or PO, so as to reduce signaling overhead and configuration complexity. Taking the network device as a base station as an example, the technical solutions of the embodiments of the present disclosure are further illustrated.

The base station or the base station obtains it from the core network as a reference for the time domain position of the resource for configuring the TRS/CRS by the base station. As an implementation, the UE can report a capability configuration gap for DRX/eDRX; as another implementation, the UE can report the GAP indication capability for the eDRX scenario. In the eDRX configuration scenario, the eDRX gap is used for the first PF/PO in the Paging Time Window (PTW), and it can also be used for the DRX gap in the eDRX configuration scenario. PF/PO.

In the embodiment of the present disclosure, the offset configuration of the time domain position of the TRS/CRS resource delivered by the base station to the UE relative to the starting point of the PF frame/PO may be different from the capability supported by the UE: the UE needs to determine the monitoring time of TRS/CRS according to the rules. Or, if the time domain position of the TRS/CRS resource delivered by the base station to the UE is the same as the offset configuration of the starting point of the PF frame/PO and the value supported by the UE, the UE wakes up in advance according to this value and performs time-frequency domain synchronization with the TRS/CRS resource configuration .

As an example, if the offset of the time domain position of the TRS/CRS resource delivered to the UE relative to the starting point of the PF frame/PO is greater than the value supported by the UE, the UE monitors the reference signal in a continuous monitoring manner. The offset of the TRS/CRS relative to the starting point of the PF frame/PO is greater than the offset of the TRS/CRS configured by the network device relative to the starting point of the PF frame/PO, which exceeds the monitoring capability of the UE. In this case, the UE abandons the DTX mode. , continuously monitor the TRS/CRS; or the UE receives the second offset of the reference signal reconfigured by the network device relative to the starting point of the PF/PO. As an example, the second offset may be no less than The offset between the reference signal supported by the UE and the PF/PO, at this time, the UE can monitor the TRS/CRS based on the second offset; of course, the second offset can still be smaller than that supported by the UE Offset from reference signal to PF/PO. As an implementation manner, the UE may also monitor the reference signal according to the offset between the reference signal supported by the UE and the PF/PO, and perform time-frequency domain synchronization based on the reference signal. At this time, the UE may miss the reference signal. In the embodiment of the present disclosure, the period of the TRS/CRS resource delivered by the base station is {10ms, 20ms, 40ms, 80ms, 160ms}.

In the embodiment of the present disclosure, when the network device binds the TRS/CRS period and the paging frame period, the base station does not need to issue the TRS/CRS period configuration at this time. Specifically, the base station can send indication information such as oneT, halfT, quarterT, oneEighthT, oneSixteenthT, etc. to the UE. The indication information of oneT, halfT, quarterT, oneEighthT, and oneSixteenthT corresponds to the sending period of the indication reference signal of 10ms, 20ms, 40ms, 80ms, and 160ms, respectively. .

As an embodiment, the SSB configuration period=5ms, and no TRS is required; as an embodiment, the SSB configuration period=10ms, and no TRS is required; as an embodiment, the SSB configuration period and the paging frame interval are the same or less than If the paging frame interval is set and the PF is configured close to the SSB, no TRS is required. For example, the PF is the next radio frame next to the SSB. As an embodiment, when pagingSearchSpace=0 and the multiplexing mode is Mode 2 or Mode 3, TRS is not required. That is to say, when the paging frame density is more sparse than the SSB configuration period, each paging PF can always find the corresponding SSB, and when the PF and SSB are frequency-division multiplexed, there is no need to send TRS, and no TRS configuration is required. information.
