Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The method for measuring the adjacent region in the embodiment is applied to the NR terminal. As shown in fig. 1, the method for measuring a neighboring cell of this embodiment includes:
s101, configuring a measurement frequency point to support N times of antenna time-sharing reception;
the N-time antenna time-sharing reception of the measurement frequency point corresponds to M receiving antennas used for each adjacent area measurement in the NR terminal, N is more than or equal to 2 and less than or equal to M, and M, N are integers;
the antenna sets corresponding to the target receiving antennas which are received by the antennas in a time-sharing manner at each time are not intersected, and the antenna sets formed by all the target receiving antennas which are received by the antennas in a time-sharing manner for N times are M receiving antennas;
for example, when M is 4, N is 4 and the number of target receiving antennas received per antenna division is 1.
When M is 4, N is 2 and the number of target receiving antennas received per antenna division is 2.
The following is specifically described by taking M ═ 4 and N ═ 2 as examples:
receiving antenna set S ═ { Rx corresponding to target measurement frequency point0,Rx1,Rx2,Rx3And configuring a target measurement frequency point to support N times of antenna time-sharing reception (namely, completing data reception by dividing into N times), wherein the antenna set used for data reception, storage and processing for the nth time (N is 1, …, N) is SnIn which S is1∪S2…∪SNS as S, any of i and ji∩Sj0(i ≠ j, i and j take values of 1, …, N); after the target frequency point finishes N times of receiving, storing and processing, the S is pressed againnAnd carrying out a new round of receiving, storing and processing.
When N is 2, S1＝{Rx0,Rx2}，S2＝{Rx1,Rx3Dividing a target measurement frequency point into 2 times of data receiving, storing and processing; the target receiving antenna for the 1 st time-sharing reception is S1Rx in (1)0,Rx2The target receiving antenna for the 2 nd time-division reception is S2Rx in (1)1,Rx3(ii) a The target receiving antenna for the 3 rd time-sharing reception is S1Rx in (1)0,Rx2The above steps are repeated, so as to obtain the received data corresponding to the 4 receiving antennas of each measuring cell (neighboring cell).
When N is 2, S1And S2There are 3 combinations: rx0,Rx1And Rx2,Rx3、Rx0,Rx2And Rx1,Rx3And Rx0,Rx3And Rx1,Rx2. When N is equal to 1, the number of corresponding permutation and combination is greater, the measurement period of 4 receiving antennas completing the cell is longer, and the specific configuration process is similar to that when the principle N is equal to 2, and therefore, the detailed description is omitted here.
S102, selecting a target receiving antenna for receiving data in a time-sharing manner under a target measurement frequency point;
s103, obtaining measurement results corresponding to M receiving antennas of a neighboring region under a target measurement frequency point according to data received by the target receiving antenna;
and S104, acquiring a target measurement value of the adjacent cell according to the measurement result.
In the embodiment, in the measurement of the neighbor cell of the NR terminal, the measurement frequency is configured with a support antenna for time-sharing reception, and the M reception antennas in the neighbor cell of the frequency are measured through N times of time-sharing reception and processing of the antennas, so that the mobility requirement is maintained, the amount of data cached in a unit time is effectively reduced, the bandwidth requirement of the cell measurement on DDR read/write is reduced, the effective bandwidth of the cell measurement is ensured, the performance of cell reselection and handover is improved, and the occurrence of situations such as processing delay due to potential DDR write/read blocking of other functional modules caused by writing/reading of a large amount of data of DDR by the cell measurement is avoided.
Example 2
As shown in fig. 2, the method for measuring a neighboring cell in this embodiment is a further improvement of embodiment 1, and specifically:
step S101 is preceded by:
s10101, acquiring data quantity which needs to be received and stored in unit time of each measurement frequency point in the list of frequency points to be measured;
s10102, judging whether the data volume is larger than a set threshold value, if so, executing a step S101; if not, configuring the measurement frequency point to support M receiving antennas to receive simultaneously.
Each measuring frequency point can independently configure whether to support antenna time-sharing reception or not, and the data size received and stored by the measuring frequency point in unit time is mainly determined. Taking M as an example of 4, when the data volume received by 4 receiving antennas is not greater than the set value, it is determined that the measurement frequency point does not need to configure a supporting antenna for time-sharing reception, and therefore the measurement frequency point is generally set according to the reference signal type and the measurement bandwidth configured by the measurement frequency point.
For example, the SSB (Single Side Band) frequency domain fixedly receives 20 RBs (Resource blocks ), and when the scs is 15khz, the data amount in the unit time is not large (the total data amount is not small, and time domain data with a length of 5ms is received), generally, it is not necessary to perform antenna time-sharing reception on the measurement frequency point; however, for scs (subcarrier spacing) of 30khz, the data amount per unit time is doubled, and for scs of 60khz, the data amount per unit time is increased by four times, so that it is necessary to determine whether the measurement frequency point needs to support antenna time-sharing reception according to actual requirements.
The frequency domain bandwidth of CSI-RS (a reference signal) is at least 24 RB, and whether a measurement frequency point needs to support antenna time-sharing reception or not is determined according to the measurement bandwidth, scs and actual requirements;
the measurement reference signal network of each measurement frequency point is configured with 3 cases: and only SSB, only CSI-RS, both SSB and CSI-RS are provided, and the measurement frequency point can be set to support antenna time-sharing reception under the condition of both SSB and CSI-RS.
After step S101 and before step S102, the method further includes:
s10201, acquiring a measurement frequency point from a to-be-measured frequency point list as a target measurement frequency point;
s10202, judging whether a target measurement frequency point supports antenna time-sharing reception, if so, acquiring a use scene corresponding to a DDR in the NR terminal;
s10203, judging whether the use scene belongs to a set scene, if so, triggering a measurement frequency point to start and support N times of antenna time-sharing reception; otherwise, triggering the measurement frequency point to start M receiving antennas for receiving simultaneously.
The measurement frequency points configured with the antennas for time-sharing reception are not necessarily received in time-sharing manner, and can be triggered according to an actual use scene, for example, when the actual use scene is a low-rate data service, the measurement frequency points are not triggered to start time-sharing reception; and when the actual use scene is a high-speed data service, triggering the measurement frequency point to start time-sharing reception.
In addition, in order to simplify the implementation, the measurement frequency point can be set to trigger the antenna time-sharing reception in all use scenes, and the specific trigger condition can be configured and adjusted according to the actual requirement.
When the measurement frequency points of the neighboring cell are sequentially received by the N antennas in a time-sharing manner, step S103 includes:
s1031, for each adjacent cell, processing data received by the target receiving antenna by using a measurement accelerator, acquiring M first processing results, and respectively storing the M first processing results;
each first processing result corresponds to one receiving antenna;
s1032, when the target measurement frequency point reaches a set reporting period, acquiring first measurement values of K sampling points under each receiving antenna according to a first processing result;
when the target measurement frequency point does not reach the reporting period, the next measurement frequency point obtained from the list of frequency points to be measured according to the set sequence is continuously used as the target measurement frequency point, and step S10202 is executed again.
S1033, performing physical layer filtering processing on the first measurement value to obtain measurement smooth values corresponding to M receiving antennas of each neighboring cell;
step S104 includes:
s1041, obtaining a target measurement value of each neighboring cell according to the measurement smooth value.
Specifically, the maximum value of the measurement smooth values of the M receiving antennas of the neighboring cell is used as a target measurement value of the neighboring cell; or the like, or, alternatively,
and weighting the measurement smooth values of the M receiving antennas of the adjacent region to obtain a weighting result, and taking the weighting result as a target measurement value of the adjacent region.
And obtaining the target measurement value of each neighboring cell by adopting other modes according to the measurement smooth value according to the actual situation.
When the measured data of the target measuring frequency point is according to the antenna S1＝{Rx0,Rx2And antenna S2＝{Rx1,Rx3When time-sharing reception is carried out for 2 times, the target measurement frequency point can obtain first measurement values of 4 receiving antennas through 2 times of data reception, wherein the sampling period of each receiving antenna is 2 times of the data receiving period; after data reception for a set number of times, the sampling point of each receiving antenna is subjected to physical layer filtering processing to obtain a first measured value corresponding to the receiving antenna, and then the first measured values corresponding to the 4 receiving antennas are combined to finally obtain a target measured value corresponding to each neighboring cell.
Step S104 is followed by:
reporting the target measurement value to a high layer;
removing target measured values corresponding to all adjacent cells under the target measuring frequency point;
and judging whether to continue the neighbor cell measurement, if so, taking the next measurement frequency point obtained from the frequency point list to be measured according to the set sequence as a target measurement frequency point, and executing step S10202 again, and then starting a new round of neighbor cell measurement on the target measurement frequency point, wherein the specific measurement process is similar to that described above, and therefore the detailed description is omitted here.
In this embodiment, when the measurement frequency does not support antenna time-sharing reception or when the measurement frequency does not need to trigger antenna time-sharing reception, the M reception antennas receive simultaneously based on normally configured hardware (radio frequency RF, automatic gain control AGC, digital front end DFE, measurement accelerator ACC), and the measurement accelerator outputs a measurement result of a cell and stores the measurement result according to the antenna.
When the measurement frequency point needs to trigger antenna time-sharing reception, time-sharing reception and processing are carried out on a target receiving antenna appointed by software configuration hardware (radio frequency RF, automatic gain control AGC, digital front end DFE and measurement accelerator ACC), and measurement accelerator outputs the measurement result of a cell and respectively and independently stores the measurement result according to the appointed antenna.
Namely, the radio frequency RF, the automatic gain control AGC, the digital front end DFE, the measurement accelerator ACC in the present embodiment support simultaneous reception and buffering of DDR to NR terminals for 4 receive antennas, and off-line processing by reading buffered receive data of 4 receive antennas at maximum from DDR, while also supporting reception and processing of measurement data configured into X (1/2/4) receive antennas by software; the NR terminal estimates DDR read/write bandwidth requirements of cell measurement according to current service conditions and configuration conditions of cell measurement, starts time division multiplexing of an antenna in time to receive and process measurement data of the NR cell, and reduces read/write load of DDR under the condition of ensuring cell mobility to the maximum extent, thereby reducing the bandwidth requirements of the cell measurement on DDR read/write.
In the embodiment, in the measurement of the adjacent cell of the NR terminal, the measurement frequency is configured with a support antenna for time-sharing reception, and the M reception antennas in the adjacent cell of the frequency are measured through N times of antenna time-sharing reception and processing, so that the requirement on mobility is maintained, the amount of data cached in a unit time is effectively reduced, the requirement on the DDR read/write bandwidth in cell measurement is reduced, the effective bandwidth in cell measurement is ensured, and the performance of cell reselection and handover is improved; in addition, on the basis of not increasing hardware cost, time-sharing reception can be started in time when the read/write bandwidth of the DDR of the NR terminal is short, and the flexibility of cell measurement and the inheritance of a platform are improved.

for example, when M is 4, N is 4 and the number of target receiving antennas received per antenna division is 1.
When M is 4, N is 2 and the number of target receiving antennas received per antenna division is 2.
The following is specifically described by taking M ═ 4 and N ═ 2 as examples:
receiving antenna set S ═ { Rx corresponding to target measurement frequency point0,Rx1,Rx2,Rx3And configuring a target measurement frequency point to support N times of antenna time-sharing reception (namely, completing data reception by dividing into N times), wherein the antenna set used for data reception, storage and processing for the nth time (N is 1, …, N) is SnIn which S is1∪S2…∪SNS as S, any of i and ji∩Sj0(i ≠ j, i and j take values of 1, …, N); after the target frequency point finishes N times of receiving, storing and processing, the S is pressed againnAnd carrying out a new round of receiving, storing and processing.
When N is 2, S1＝{Rx0,Rx2}，S2＝{Rx1,Rx3Dividing a target measurement frequency point into 2 times of data receiving, storing and processing; the target receiving antenna for the 1 st time-sharing reception is S1Rx in (1)0,Rx2The target receiving antenna for the 2 nd time-division reception is S2Rx in (1)1,Rx3(ii) a The target receiving antenna for the 3 rd time-sharing reception is S1Rx in (1)0,Rx2The above steps are repeated, so as to obtain the received data corresponding to the 4 receiving antennas of each measuring cell (neighboring cell).

When N is equal to 1, the number of corresponding permutation and combination is greater, the measurement period of 4 receiving antennas completing the cell is longer, and the specific configuration process is similar to that when the principle N is equal to 2, and therefore, the detailed description is omitted here.
