It is the process for the processing method that a kind of downlink reference signal provided in an embodiment of the present invention occupies referring to Fig. 1, Fig. 1 Figure, as shown in Figure 1, comprising the following steps:

Step 101, the RS information preempted is obtained；

The processing method that downlink reference signal provided in an embodiment of the present invention occupies is applied to user terminal, for working as downlink Reference signal is decoded the processing of control when occupying.

In the present embodiment, the content that above-mentioned RS information includes can be configured according to actual needs, such as may include Type, quantity and the position of RS.

Above-mentioned preemption can be realized by way of punching (puncture).

Specifically, the mode that user terminal obtains the RS information preempted can be configured according to the actual situation, such as Instruction information can directly be passed through by network side equipment to be indicated, can also be indicated indirectly by signaling, that is, above-mentioned steps 101 include the instruction information for obtaining network side equipment and sending, and obtains the RS information preempted；Or the letter according to network side equipment Enable the RS information for inferring and determining and being preempted.For example, when network side equipment needs to dispatch the transmission of URLLC business, it may be pre- Account for the signal that a part is carrying out eMBB business, it is also possible to the signal that a part is carrying out eMBB business will not be preempted.This Inventive embodiments are for the processing that can preempt the case where a part is carrying out the signal of eMBB business.Wherein, the money of preemption Source includes RS resource, i.e., can preempt RS.The information network side apparatus of preemption can be referred to by descending control signaling, such as preemption Show (preemption indication) or dedicated (UE-specific) Downlink Control Information (downlink of UE Control information, DCI), notify which running time-frequency resource of UE or the data block of which scheduling are preempted.

Step 102, determined whether to carry out weight to target service data according to the RS not preempted according to preemption status information New decoding, the preemption status information are used to indicate the state that the user terminal RS allows to be preempted.

In the step, above-mentioned preemption status information can be determined by network side or by protocol configuration, specifically, preemption Status information may include allow the maximum RS number preempted and RS to allow to be preempted position at least one, pass through RS The several and position RS at least one indicating user terminal RS allows occupied state.

For example, in the present embodiment, user terminal can be obtained according to the descending control signaling that network side equipment is sent first The information preempted in target service data is taken, so that it is determined which running time-frequency resource and/or which data block are camped on, then According to the relationship between preemption status information and the information preempted, that is, can determine whether can be according to the RS not preempted to mesh Mark business datum is decoded again.If can decode again, according to the RS that is not preempted attempt to target service data into Row decoding.

It should be noted that the target service data are not decoded again if the user terminal is determining, or Again decoding failure then feeds back negative response (NACK) to network side equipment.Specifically, user terminal can be corresponding HARQ-ACK feeds back timing (timing) and feeds back NACK, then re-starts target service data according to NACK by network side equipment Transmission.

It should be noted that above-mentioned preemption status information can be determined by network side or by protocol configuration, referring to figure 2, according to network configuration, then before above-mentioned steps 102, this method further include:

Step 103, the preemption status information that network side equipment is sent is received.

Specifically, network side setting can directly configure the preemption status information of user terminal according to agreement.But due to It is different that different user terminals corresponds to the state that RS allows to be preempted, that is to say, that can be carried out according to the ability of user terminal Preempt the configuration of status information.Attempt decoded success rate to improve user terminal, in the present embodiment, as shown in figure 3, Before above-mentioned steps 103, this method can also include:

Step 104, the ability information of user terminal is sent to network side equipment, the ability information for network side for setting It is standby to configure the preemption status information.

In the step, aforementioned capabilities information may include buffer memory capacity and processing time of user terminal etc..Such as user The buffer memory capacity of terminal is big, and the RS number that the preemption status information user terminal of configuration allows to be preempted is larger；User terminal delays Deposit that capacity is small, the RS number that the preemption status information user terminal of configuration allows to be preempted is smaller, once RS preempted, just put Abandon the decoding (RS not being allowed to be preempted) of data.At the same time, if the short processing time of user terminal, the preemption state of configuration In information, the RS for allowing time (i.e. time-frequency resource location) forward is preempted；The processing time of user terminal is longer, then only allows Time (i.e. time-frequency resource location), RS rearward was preempted, once or RS preempted, the decoding for just abandoning data (does not allow RS It is preempted).

It should be noted that above-mentioned RS number may include the corresponding antenna port quantity of RS and the corresponding running time-frequency resource of RS Quantity at least one.

In the present embodiment, network side equipment can be configured based on antenna port quantity allows the RS number that is preempted, i.e., and RS pairs The antenna port quantity answered；The RS number that can also allow to be preempted based on running time-frequency resource quantity configuration, the i.e. corresponding time-frequency money of RS Source quantity.Specifically, the RS number configured in one embodiment only includes antenna port quantity or running time-frequency resource quantity；Another The RS number configured in embodiment includes antenna port quantity and running time-frequency resource quantity.Following embodiment carries out specifically this It is bright.

Specifically, above-mentioned steps 102, comprising:

Step 1021, if the RS number preempted is less than or equal to the RS number for allowing maximum to be preempted, it is determined that institute Target service data are stated to be decoded again；

Step 1022, if the RS number preempted is greater than the RS number for allowing maximum to be preempted, it is determined that abandon to described The decoding again of target service data.

In the present embodiment, the type of above-mentioned RS can be configured according to actual needs, such as RS may include RS demodulation Reference signal DMRS and Phase Tracking reference signal PTRS at least one.When preempting DMRS, above-mentioned RS number be can wrap Include the corresponding antenna port quantity of RS and the corresponding running time-frequency resource quantity of RS at least one, below to being under different situations No determination carries out decoding again to the target service data and is illustrated:

For example, the first situation: indicate that the RS number that is preempted of DMRS maximum is N in above-mentioned preemption status information, with symbol/ Number of time slots is unit, if getting in the RS information preempted has Y symbol/time slot DMRS to be preempted.As Y≤N, then use Family terminal can be attempted to decode target service data.Specifically, channel estimation is carried out in the DMRS that can be never preempted, obtain Channel information is got, target service data are decoded again.Due to attempt decoding need to cache a large amount of original number it is believed that Breath such as I/Q data, thus it is more demanding for ability of user terminal.As Y > N, the solution again for the business datum that forgoes one's aim Code.

Second situation: the RS number for indicating that DMRS maximum is preempted in above-mentioned preemption status information is N, with antenna port number For unit, if getting in the RS information preempted has the DMRS of Y antenna port to be preempted.As Y≤N, then user terminal can To attempt to decode target service data.Specifically, channel estimation is carried out in the DMRS that can be never preempted, channel is got Information decodes target service data again.Need to cache a large amount of primary data information (pdi) such as I/Q number due to attempting decoding According to, therefore it is more demanding for ability of user terminal.As Y > N, the decoding again for the business datum that forgoes one's aim.

The third situation: the antenna port number for indicating that DMRS maximum is preempted in above-mentioned preemption status information is N, is captured Symbol/number of time slots be M, if getting in the RS information preempted has X antenna port and Y symbol/time slot DMRS It is preempted.As Y≤M and X≤N, then user terminal trial is decoded target service data.

When preempting PTRS, above-mentioned RS number may include the corresponding antenna port quantity of RS or the corresponding running time-frequency resource number of RS Amount, below to whether determined under different situations to the target service data carry out again decoding be illustrated:

For example, the first situation: indicate that the RS number that is preempted of PTRS maximum is N in above-mentioned preemption status information, with symbol/ Number of time slots is unit, if getting in the RS information preempted has Y symbol/time slot PTRS to be preempted.As Y≤N, then use Family terminal can be attempted to decode target service data.Estimate specifically, phase noise is carried out in the PTRS that can be never preempted Meter, gets phase noise information and compensated information, is decoded again to target service data.It needs to delay due to attempting decoding A large amount of primary data information (pdi) such as I/Q data are deposited, therefore more demanding for ability of user terminal.As Y > N, forgo one's aim The decoding again of business datum.

Second situation: the RS number for indicating that PTRS maximum is preempted in above-mentioned preemption status information is N, with antenna port number For unit, if getting in the RS information preempted has the PTRS of Y antenna port to be preempted.As Y≤N, then user terminal can To attempt to decode target service data.Specifically, phase noise estimation is carried out in the PTRS that can be never preempted, get Phase noise information and compensated information decode target service data again.It needs to cache largely due to attempting to decode Primary data information (pdi) such as I/Q data, thus it is more demanding for ability of user terminal.As Y > N, forgo one's aim business datum Decoding again.

Further, when the preemption status information includes the position for allowing to be preempted, above-mentioned steps 102 include:

Step 1023, if the position RS preempted all belongs to the position that RS allows to be preempted in the preemption status information It sets, it is determined that the target service data are decoded again according to the RS not preempted.
