Description

Information processing method and device

[ technical field ] A method for producing a semiconductor device

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing information.

[ background of the invention ]

With the rapid development of wireless communication technologies, more and more technologies are provided for providing services based on wireless spectrum resources. However, due to the limited range of available wireless spectrum resources, the wireless spectrum resources have been increasingly crowded in recent decades, and it is difficult to find the licensed spectrum that can be exclusively used. Therefore, LTE (Long Term Evolution) communication systems operating in unlicensed frequency bands, which are generally based on LBT (Listen Before Talk) technology, share spectrum with DECT (Digital Enhanced Cordless communications) systems.

The resource distribution of the DECT system and the LTE communication system operating in the unlicensed frequency band in the frequency domain is shown in fig. 1, in which the F2 sub-band, the F3 sub-band, and the F4 sub-band of the DECT system are multiplexed by the LTE communication system operating in the unlicensed frequency band.

At present, an LTE communication system working in an unlicensed frequency band monitors DECT system signals with three sub-bands, namely, an F2 sub-band, an F3 sub-band and an F4 sub-band, as one unit, and cannot run LTE services when LBT of any one sub-band fails (that is, the sub-band is detected to have DECT system signals); and running the LTE service until the LBT of all three sub-bands is successful.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

the LTE communication system working in the unlicensed frequency band listens to signals of the DECT system with three sub-bands, namely, a F2 sub-band, a F3 sub-band and a F4 sub-band, and when any one of the sub-bands has a DECT system signal, the LTE service cannot be operated, so that the utilization rate of the sub-bands by the LTE communication system working in the unlicensed frequency band is low, and the transmission capability cannot meet the communication requirement.

[ detailed description ] embodiments

For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.

It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.

The embodiment of the invention provides an information processing method, which is applied to an unauthorized frequency band LTE communication system sharing a frequency spectrum with a DECT system based on an LBT technology, and is suitable for an interception process of an LTE base station working in an unauthorized frequency band on a DECT system signal, as shown in figure 2, the method comprises the following steps:

102. and taking a sub-band as a detection unit, when detecting that a DECT system signal does not exist on a first appointed sub-band and a DECT system signal exists on a second appointed sub-band, operating a Long Term Evolution (LTE) service on the first appointed sub-band, and testing the DECT system signal on the second appointed sub-band to obtain a test result.

Wherein the first designated sub-band refers to the F2 sub-band and the F4 sub-band of the DECT system, and the second designated sub-band refers to the F3 sub-band of the DECT system. It should be noted that, as shown in fig. 1, the DECT system is a communication system operating in Band39 frequency Band, and the frequency spectrum occupied by the DECT system is divided into six sub-bands F1, F2, F3, F4, F5, and F6, each of which is 1.728MHz (megahertz). The F2 sub-band, F3 sub-band, and F4 sub-band of the DECT system may be multiplexed by the LTE communication system operating in the unlicensed frequency band. In the embodiment of the invention, the frequency spectrum distribution of the LTE communication system has two modes as shown in the figure, wherein each sub-band of the first mode occupies 1.4MHz bandwidth and is divided into three sub-bands; the second way occupies the full bandwidth of 5 MHz.

Specifically, the LTE service refers to an Uplink LTE service, and includes transmission of an Uplink Control Channel (PUCCH) and transmission of an Uplink Shared Channel (PUSCH). The PUCCH is used to carry uplink control signals, and the PUSCH is used to carry uplink data transmission or uplink control signals. In a specific embodiment, an LTE communication system operating in an unlicensed band transmits PUCCH and PUSCH on F2 and F4 sub-bands, and transmits only PUSCH on F3 sub-band. Therefore, as long as there is no DECT signal on the F2 sub-band and the F4 sub-band, the uplink LTE traffic can be operated on the F2 sub-band and the F4 sub-band.

In step 102, when it is detected that there is no digital enhanced cordless telecommunications system signal on the first designated sub-band and a DECT system signal on the second designated sub-band, at this time, the central 11 physical resource block pairs of the second designated sub-band cannot be used for scheduling and allocating uplink resources, the LTE service is run only on the first designated sub-band, and the DECT system signal is tested on the second designated sub-band.

104. And when the test result indicates that the second appointed sub-band does not have a DECT system signal, operating LTE service on the first appointed sub-band and the second appointed sub-band.

Specifically, if the test result on the second designated sub-band indicates that no DECT system signal exists, it is considered that the uplink resources can be scheduled and allocated on both the first designated sub-band and the second designated sub-band (i.e., the full bandwidth of the unlicensed band LTE communication system), and at this time, the LTE service is operated on the full bandwidth of the unlicensed band LTE communication system.

106. And when the test result indicates that the DECT system signal exists in the second designated sub-band, continuing to operate the LTE service on the first designated sub-band, and continuing to test the DECT system signal on the second designated sub-band.

Specifically, if the test result on the second designated subband indicates that the DECT system signal exists, the second designated subband is considered to be still unable to schedule and allocate the uplink resource, at this time, the LTE service is kept running on the first designated subband, and the DECT system signal is continuously tested on the second designated subband.

When the test results are different, the process is performed in two different ways, step 104 and step 106. And, in step 106, continuing to test the DECT system signal on the second designated sub-band, and when the test result indicates that the DECT system signal is not present in the second designated sub-band, operating the LTE service on the first designated sub-band and the second designated sub-band.

The embodiment of the invention provides an information processing method, which takes sub-bands as detection units, when a DECT system signal does not exist on a first appointed sub-band is detected, an LTE service is firstly operated on the first appointed sub-band, at the moment, the DECT system signal is tested on a second appointed sub-band independently, and when the test result indicates that the DECT system signal does not exist on the second appointed sub-band, the LTE service is started to be operated on the first appointed sub-band and the second appointed sub-band simultaneously. According to the technical scheme provided by the embodiment of the invention, when the first designated sub-band is available, the LTE service starts to operate, and when the second designated sub-band is available, the LTE service is instantly operated at the first designated sub-band and the second designated sub-band simultaneously, so that the utilization rate of the sub-band by the LTE communication system working in an unauthorized frequency band is improved, and the transmission capability of the LTE communication system can better meet the communication requirement.

Further, with reference to the foregoing method flow, another possible implementation manner of the embodiment of the present invention provides, for a specific manner of operating the LTE service on the first designated sub-band and the second designated sub-band in step 104, the following method flow, as shown in fig. 3, where step 104 includes:

1041. and when the test result indicates that the second designated sub-band does not have a DECT system signal, transmitting PUCCH and PUSCH on the first designated sub-band, and transmitting PUSCH on the second designated sub-band.

Further, in combination with the foregoing method flow, another possible implementation manner of the embodiment of the present invention provides the following method flow for a specific implementation manner of how to test the DECT system signal on the second designated sub-band in step 102, as shown in fig. 4, where step 102 includes:

1021. and selecting a plurality of terminals requesting to operate the LTE service.

Specifically, a plurality of terminals are selected as test terminals from the terminals requesting to run the uplink LTE service. If the Uplink Modulation and Coding Scheme U-MCS of the selected terminal is used as a criterion for determining the quality of the channel, the Uplink Modulation orders of a plurality of terminals are greater than a specified value, and the specified value may be 22 or 24.

1022. And transmitting the PUSCH of the plurality of terminals on a second designated sub-band of the designated sub-frame.

The designated subframe may be a pair of subframes consisting of subframe 2 and subframe 7 of an LTE system frame, or may also be a pair of subframes consisting of subframe 3 and subframe 8 of an LTE system frame, or a pair of subframes corresponding to a pair of uplink and downlink transmission slots (one pair slots) in the DECT system. Specifically, as shown in fig. 5, it can be seen from fig. 5 that the LTE system frame is divided into ten subframes 0 to 9, the DECT system frame is divided into twelve time slots 0 to 11, subframe 2 and subframe 7 of the LTE system frame correspond to a pair of uplink and downlink transmission time slots in the DECT system frame, and subframe 3 and subframe 8 of the LTE system frame also correspond to a pair of uplink and downlink transmission time slots in the DECT system frame. It should be noted that, by testing the DECT signals transmitted in the uplink and downlink on a pair of uplink and downlink transmission timeslots of the DECT system frame, it can be more accurately determined whether the DECT system signal occurs.

1023. And if the PUSCH transmission of the plurality of terminals is successful, determining that the test result is that the DECT system signal does not exist on the second designated subband.

1024. And if the PUSCH transmission of the plurality of terminals fails, determining that the test result is that a DECT system signal exists on the second designated subband.

When the PUSCHs of a plurality of terminals fail to be transmitted, considering that the LTE services of the plurality of terminals need to be normally operated, the PUSCHs of the plurality of terminals need to be retransmitted on a first appointed sub-band, so the number of physical resource block pairs occupied by the PUSCHs of the plurality of terminals is less than or equal to the number of available physical resource block pairs of the PUSCHs on the first appointed sub-band.

It should be noted that, a terminal with better channel quality is selected, on one hand, because uplink transmission is performed under the condition that the uplink channel quality is good, if the PUSCH still fails to be transmitted, there is a high probability that the interference caused by the DECT signal is confirmed; on the other hand, good channel quality means a higher code rate and a smaller number of redundant bits, which decreases the possibility that the base station corrects uplink transmission using redundant data, and thus the DECT signal, once it occurs, may cause a corresponding PUSCH transmission failure at a high rate.

Further, with reference to the foregoing method flow, after PUSCH transmission of a plurality of terminals fails, in order to ensure that LTE of the plurality of terminals can operate normally, PUSCH of the plurality of terminals needs to be retransmitted, so another possible implementation manner of the embodiment of the present invention further provides the following method flow, after step 1022 is executed, as shown in fig. 6, step 102 further includes:

1025. and if the PUSCHs of the plurality of terminals fail to be transmitted, retransmitting the PUSCHs of the plurality of terminals on the first appointed sub-band.

Furthermore, in combination with the above method flow, a period for testing the DECT system signal on the second designated stator band may be set by the timer so as to avoid frequent testing of the DECT system signal on the second designated stator band. Therefore, another possible implementation manner of the embodiment of the present invention is directed to implementation of step 102, and further provides the following method flow, as shown in fig. 7, step 102 is specifically executed as:

1026. and after the LTE service is operated on the first appointed sub-band, starting a timer, and after the timer is overtime, if the DECT system signals still exist in the second appointed sub-band, testing the DECT system signals on the second appointed sub-band to obtain a test result.

The function of the timer is to set a test period for the DECT system signal, and to test the DECT signal on the second designated stator band after the timer has expired. And when the DECT system signal continues to be tested on the second designated sub-band in step 106, the test period may also be set by a timer.

Further, in combination with the foregoing method flow, since the second designated subband cannot be used for scheduling and allocating uplink resources when a DECT system signal exists on the second designated subband, and thus a Physical Random Access Channel (PRACH) needs to be transmitted on the first designated subband, another possible implementation manner of the embodiment of the present invention further provides the following method flow, which is executed after step 102, as shown in fig. 8, and further includes:

103. and configuring a physical resource block pair occupied by a Physical Random Access Channel (PRACH) to be positioned on the first designated sub-band.

The embodiment of the invention provides an information processing method, which is applied to an unauthorized frequency band LTE communication system sharing a frequency spectrum with a DECT system based on an LBT technology, and is suitable for a process of monitoring signals of the DECT system by a base station working in the unauthorized frequency band, as shown in figure 9, the method comprises the following steps:

202. and taking the sub-band as a detection unit, and when the DECT system signal does not exist on the first appointed sub-band and the DECT system signal exists on the second appointed sub-band, operating the Long Term Evolution (LTE) service on the first appointed sub-band.

The LTE service at least comprises one of uplink GBR service and uplink non-GBR service. Wherein, GBR is called Guaranteed Bit Rate, and translated into Guaranteed Bit Rate, GBR service refers to service with lowest Guaranteed Rate, and generally includes ductility sensitive service such as voice call, video chat, etc.; non-GBR traffic, which refers to traffic without the lowest guaranteed rate (only the maximum rate limit), generally includes traffic that is not ductility insensitive, such as file downloading, web browsing, etc.

The first designated sub-band and the second designated sub-band are explained in step 102, and are not described herein again.

204. And if the running uplink GBR service exists in the current cell, rejecting a terminal access request and an uplink GBR service request of the current cell, and stopping the running uplink non-GBR service of the current cell after the running of the running uplink GBR service is finished.

It should be noted that, considering that some base stations can only test the DECT system signals on the first designated sub-band and the second designated sub-band simultaneously, before starting the test, the LTE service currently running in the cell needs to be interrupted based on the method described in step 204 so as not to interfere with the test of the DECT system signals on the first designated sub-band and the second designated sub-band.

206. And testing the DECT system signal on the first designated sub-band and the second designated sub-band to obtain a test result.

The test method can be a traditional detection method, namely, the strength of the DECT system signal on certain OFDM symbols in an uplink system frame is detected, and whether the DECT system signal exists is judged according to a strength threshold value; the method may also be similar to the method described in steps 1021 to 1024, and specifically may transmit the PUCCH on the first designated subband, transmit the PUSCH on the second designated subband, and determine whether the DECT system signal exists according to the transmission condition of the PUCCH and the PUSCH.

208. And when the test result indicates that the second appointed sub-band does not have a DECT system signal, operating LTE service on the first appointed sub-band and the second appointed sub-band.

Specifically, it may be assumed that no DECT system signal exists on the first designated subband, and therefore, when the test result indicates that no DECT system signal exists on the second designated subband, it is considered that the first designated subband and the second designated subband (i.e., the full bandwidth of the unlicensed band LTE communication system) may both schedule and allocate uplink resources, and at this time, the LTE service is operated on the full bandwidth of the unlicensed band LTE communication system.

210. When the test result indicates that the DECT system signal exists in the second designated sub-band, continuing to test the DECT system signal on the first designated sub-band and the second designated sub-band.

Specifically, if the test result indicates that the DECT system signal exists on the second designated subband, the second designated subband is considered to be still unable to schedule and allocate the uplink resource, and at this time, the DECT system signal is continuously tested on the first designated subband and the second designated subband.

According to the technical scheme provided by the embodiment of the invention, when the first designated sub-band is available, the LTE service starts to operate, and when the second designated sub-band is available, the LTE service is instantly operated at the first designated sub-band and the second designated sub-band simultaneously, so that the utilization rate of the sub-band by the LTE communication system working in an unauthorized frequency band is improved, and the transmission capability of the LTE communication system can better meet the communication requirement.

Furthermore, in combination with the foregoing method flow, a period for testing the DECT system signal on the first designated sub-band and the second designated sub-band may be set by the timer, so as to avoid the need to frequently interrupt the running LTE service before testing. Therefore, another possible implementation manner of the embodiment of the present invention is directed to the implementation of step 204, and further provides the following method flow, as shown in fig. 10, step 204 is specifically executed as:

2041. and after the LTE service is operated on the first appointed sub-band, starting a timer, after the timer is overtime, if the operating uplink GBR service still exists in the current cell, rejecting a terminal access request and an uplink GBR service request of the current cell, and stopping the operating uplink non-GBR service of the current cell after the operation of the operating uplink GBR service is finished.

The function of the timer is to set a test period for the DECT system signal, and to test the DECT signal in the first and second designated sub-bands after the timer has reached the time. And in step 210, when the DECT system signal is continuously tested on the first designated sub-band and the second designated sub-band, the test period may also be set by a timer.

Further, in combination with the foregoing method flow, since the second designated subband cannot be used for scheduling and allocating uplink resources when a DECT system signal exists on the second designated subband, a Physical Random Access Channel (PRACH) needs to be transmitted on the first designated subband, so that another possible implementation manner of the embodiment of the present invention further provides the following method flow, which is executed after step 202, as shown in fig. 11, and further includes:
