Description

Data occupation indication method and device, network side equipment and terminal equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data occupancy indication method, a data occupancy indication apparatus, a network side device, and a terminal device.

Background

Currently, development work of a 5 th generation mobile communication system (5G) is actively underway. According to future application requirements, the 5G system needs to support a variety of service scenarios, wherein Low-Latency and high-reliability (URLLC) communication scenarios such as unmanned driving, industrial automation, and the like are receiving wide attention. Generally, URLLC data has very high burstiness and high requirement on delay, so that this type of data has very high resource scheduling priority. The existing solution proposed for the transmission of URLLC data is: when the URLLC data arrives, the 5G base station immediately schedules the URLLC data, that is, performs puncturing transmission on an enhanced Mobile Broadband (eMBB) data block in which resource allocation has been completed, so as to realize the fastest data transfer, and further meet the requirement of the URLLC data on time delay.

However, the punctured URLLC data will affect the correct demodulation of the eMBB data at the User Equipment (UE). To improve this problem, researchers have proposed that eMBB UEs may be provided with information related to URLLC data in received data, such as the location of URLLC data, by setting a Preemption Indication (PI), and UEs may remove URLLC data according to the information provided by the PI to improve the demodulation success rate of eMBB data. Currently, the PI supports cross-Carrier scheduling, that is, a PI received by a UE on a Component Carrier (CC) may be used to indicate a URLLC occupancy on another CC, multiple PIs may be stored in Downlink Control Information (DCI), and a terminal receives the DCI (DCI format 2_1) and obtains a URLLC data transmission condition on multiple CCs at the same time. In NR (New Radio, New wireless technology), the Bandwidth of a CC is very large, so that a terminal can support NR, the CC is divided into several Bandwidth units (BWPs), and a high layer configures 4 BWPs for a UE at most in one CC, but the UE can only use one BWP at a time, i.e., the UE accesses to a certain CC, and actually operates on a certain BWP in the CC. At present, the higher layer signaling will correspond each CC to each PI in DCI format 2_1, however, the UE supports BWP hopping, and the hopping may occur in each slot, so that, in the case shown in fig. 1 (the UE hops from BWP3 to BWP2 in the next PI cycle), if the base station does not do corresponding processing, the base station still uses PI for the indication of BWP3 according to the content configured by the higher layer signaling, and BWP3 is occupied by URLLC in the current slot, and when the terminal receives the PI indicating this slot, it will understand that BWP2 is occupied by URLLC in the current slot, but is actually not, and thus the false alarm indication occurs.

Therefore, how to optimize the information configuration mode of the PI, reduce the probability of false alarm indication, and improve the performance of the system becomes a technical problem to be solved urgently.

It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The following specifically describes a scheme of a data occupation indication method applied to a network side device according to an embodiment of the present invention with reference to fig. 2 to fig. 5.

As shown in fig. 2, the data occupancy indication method according to the embodiment of the present invention is applicable to a network side device, and specifically includes the following steps:

step 202, in the first sending period, configuring occupation indication information according to occupation information of the first type of data on a target bandwidth unit located in the second sending period of the terminal device, where the target bandwidth unit is located in the first carrier unit.

In this embodiment, the first carrier unit carrying the second type of data also carries the first type of data, in order to inform the terminal device of the specific position of the first type of data on the first carrier unit for the terminal device to accurately remove the first type of data and demodulate the second type of data, and considering that the network side device can acquire all bandwidth units in the transmission period of the occupation indication information of the terminal device, the network side device may perform configuration of the occupation indication information according to the occupation information of the first type of data on a target bandwidth unit in the first carrier unit in which the terminal device is located in the second transmission period, in the first transmission period which is after and adjacent to the second transmission period of the occupation indication information in time sequence, and it is known that the target bandwidth unit refers to a bandwidth unit in which the terminal device has operated on the first carrier unit in the second transmission period, further, the occupation indication information is sent to the terminal device in the first sending period, specifically, the occupation indication information can be sent to the terminal device on the first carrier unit, and the occupation indication information can also be sent to the terminal device on the second carrier unit different from the first carrier unit, so that the terminal device can determine the time-frequency resource occupied by the first type of data on the target bandwidth unit in the previous second sending period according to the occupation indication information, so as to improve the success rate of data demodulation.

Further, it is understood that the occupation indication information of the first type data may include occupation location information, data information, and the like of the first type data.

Further, as shown in fig. 3, step 202 in the foregoing embodiment specifically includes:

step 2022, detecting whether the terminal device jumps in the bandwidth unit on the first carrier unit in the second sending period, so as to obtain a detection result.

Step 2024, configuring the occupation indication information according to the detection result.

In this embodiment, by detecting the skip condition of the bandwidth unit of the terminal device operating on the first carrier unit in the second sending period, all the bandwidth units of the terminal device operating on the first carrier unit in the second sending period are determined, and then the dynamic configuration of the occupation indication condition of the first type of data on the target bandwidth unit is performed, so as to avoid the occurrence of the false alarm indication condition caused by the skip of the bandwidth unit where the terminal device is located, and achieve the purpose of reducing the occurrence probability of the false alarm indication.

Further, in the above embodiment, the occupation indication information includes bit information corresponding to the target bandwidth unit, where the bit information is used to indicate the time-frequency resource; and the first class data is punched and embedded into the second class data, wherein the first class data is low-delay high-reliability data, and the second class data is enhanced mobile broadband data.

In this embodiment, the indication of the time-frequency resource occupied by the first type of data on the target bandwidth unit is specifically performed according to the bit information included in the occupation indication information, so as to more effectively utilize the occupation indication bit resource in the DCI; furthermore, in order to realize the fast transmission of the first type of data, the first type of data may be subjected to puncturing transmission in the second type of data that has completed resource allocation, preferably, the first type of data is low-latency high-reliability data that has a high requirement for latency and a high resource scheduling priority, and the second type of data may be enhanced mobile broadband data that has a high throughput, and by indicating the accurate occupancy of the first type of data, the success rate of the terminal device in demodulating the enhanced mobile broadband data may be improved, and the energy consumption of the terminal device that receives the enhanced mobile broadband data may be reduced.

Further, in step 2024 in the foregoing embodiment, when performing dynamic configuration of the occupied indication content according to the target bandwidth unit condition on the first carrier unit in the second transmission period, the terminal device may be divided into two conditions: the first condition is that the terminal equipment always works on one bandwidth unit in the first carrier unit in the second sending period; the second condition is that the terminal device has jumped to the bandwidth unit in the second sending period, that is, the terminal device has worked on a plurality of bandwidth units in the first carrier unit in the second sending period. Specifically, the method comprises the following steps:

in the first case, when it is detected that the terminal device does not jump to the bandwidth unit in the second sending period, and it is determined that the target bandwidth unit only contains one bandwidth unit, the occupation indication information is configured according to the occupation information of the first type of data on the bandwidth unit.

As shown in fig. 4, if the terminal device UE1 always operates on the target bandwidth unit BWP2 of the CC1 (i.e. the first carrier unit) during the PI period (i.e. the second sending period) and no hop occurs, the occupancy indication information PI is configured according to the occupancy of the first type data URLLC on the target bandwidth unit BWP 2.

In the second case, when it is detected that the terminal device skips the bandwidth unit in the second sending period, it is determined that the target bandwidth unit includes multiple bandwidth units, and the occupation indication information is configured according to the occupation information of the first type of data on the multiple bandwidth units.

As shown in fig. 5, the terminal device UE1 has jumped the bandwidth unit on CC1 (i.e. the first carrier unit) within the PI period (i.e. the second transmission period), and jumped to bandwidth unit BWP2 by bandwidth unit BWP3, and configures occupation indication information PI according to the occupation status of the first type data URLLC on target bandwidth units BWP2 and BWP 3.

In this way, for different situations, corresponding configuration of the occupation indication information is performed according to the occupation information of the first type of data on one or more bandwidth units (i.e., target bandwidth units) where the terminal device is located in the first carrier unit in the second transmission cycle, so as to avoid the occurrence of false alarm indication caused by the terminal device jumping to the located bandwidth units.

In summary, the network side device configures occupation indication information according to the occupation situation of the first type of data in the bandwidth unit where the terminal device is located, and sends the occupation indication information to the terminal device, where the occupation indication information includes the occupation situation of the first type of data in one bandwidth unit in the sending cycle of the previous occupation indication information or in multiple bandwidth units generated by the terminal device performing bandwidth unit hopping.

Fig. 6 shows a schematic block diagram of a data occupancy indication apparatus suitable for a network side device according to an embodiment of the present invention.

As shown in fig. 6, a data occupation indicating device 30 according to an embodiment of the present invention is suitable for a network side device, and the data occupation indicating device 30 includes: a configuration module 302 and a sending module 304.

The configuration module 302 is configured to configure, in a first sending period, occupation indication information according to occupation information of a first type of data on a target bandwidth unit located in a second sending period of the terminal device, where the target bandwidth unit is located in a first carrier unit; the sending module 304 is configured to place the occupation indication information on the first carrier unit or the second carrier unit in the first sending period to send to the terminal device, so that the terminal device determines, according to the occupation indication information, a time-frequency resource occupied by the first type of data on the target bandwidth unit, where the second sending period is located before the first sending period in time order and is adjacent to the first sending period, and the first carrier unit further carries second type of data.

Further, as shown in fig. 7, the configuration module 302 in the above embodiment includes: a detection sub-module 3022 and a configuration sub-module 3024.

The detecting submodule 3022 is configured to detect whether the terminal device jumps in the bandwidth unit on the first carrier unit in the second sending period, so as to obtain a detection result; the configuration sub-module 3024 is configured to configure the occupancy indication information according to the detection result.

Further, in the above embodiment, the configuration sub-module 3024 is specifically configured to: when it is detected that the terminal device does not jump to the bandwidth unit in the second sending period, and it is determined that the target bandwidth unit only contains one bandwidth unit, configuring the occupation indication information according to the occupation information of the first type of data on the one bandwidth unit; when it is detected that the terminal device jumps in the bandwidth unit in the second sending period, determining that the target bandwidth unit includes multiple bandwidth units, and configuring the occupation indication information according to the occupation information of the first type of data in the multiple bandwidth units.

In this embodiment, when performing dynamic configuration of the occupation indication content according to the target bandwidth unit condition on the first carrier unit in which the terminal device is located in the second transmission period, specifically, two conditions are divided: the first condition is that the terminal equipment always works on one bandwidth unit in the first carrier unit in the second sending period; the second condition is that the terminal device has jumped to the bandwidth unit in the second sending period, that is, the terminal device has worked on multiple bandwidth units in the first carrier unit in the second sending period, so as to perform, for different conditions, dynamic configuration of corresponding occupation indication information according to the occupation information of the first type of data on one or more bandwidth units (that is, target bandwidth units) in the first carrier unit in the second sending period, thereby avoiding the occurrence of false alarm indication caused by the terminal device jumping to the bandwidth unit.

Further, in the above embodiment, the occupation indication information includes bit information corresponding to the target bandwidth unit, where the bit information is used to indicate the time-frequency resource.

In this embodiment, the indication of the time-frequency resource occupied by the first type of data on the target bandwidth unit is specifically performed according to the bit information included in the occupation indication information, so as to more effectively utilize the occupation indication bit resource in the DCI.

Further preferably, the bit information contains 14 bits. If the terminal equipment does not jump the bandwidth unit on the first carrier unit, 14 bits of the occupied indication information point to time-frequency information occupied by the first type data on one bandwidth unit of the first carrier unit; if the terminal device has a bandwidth unit hop on the first carrier unit, the 14 bits of the occupation indication information need to point to the time-frequency information occupied by the first type of data on multiple bandwidth units of the first carrier unit, for example, if two hops have occurred, the 14 bits of the occupation indication information need to be divided into two groups, which may be divided into equal parts or not, where one group points to the bandwidth unit before the hop, and the other group points to the bandwidth unit after the hop.

Further, in the above embodiment, the first type of data is punctured and embedded into the second type of data, where the first type of data is low-latency high-reliability data, and the second type of data is enhanced mobile broadband data.

In this embodiment, in order to implement fast delivery of the first type of data, the first type of data may be subjected to puncturing transmission in the second type of data that has completed resource configuration, preferably, the first type of data is low-latency high-reliability data that has a high requirement for latency and has a high resource scheduling priority, and the second type of data may be enhanced mobile broadband data that has a high throughput, and by indicating the accurate occupancy of the first type of data, the demodulation success rate of the enhanced mobile broadband data by the terminal device may be improved, and energy consumption of the terminal device that receives the enhanced mobile broadband data may be reduced.

A scheme of a data occupation indication method suitable for a terminal device according to an embodiment of the present invention is specifically described below with reference to fig. 9 to 11.

As shown in fig. 9, the data occupation indicating method suitable for a terminal device according to the embodiment of the present invention specifically includes the following steps:

step 502, receiving occupation indication information carried on a target carrier unit by a network side device in a first sending cycle.

Step 504, determining, according to the occupation indication information, a time-frequency resource occupied by the first type of data in a target bandwidth unit in a second sending period of the terminal device, where the second sending period is located before the first sending period in time sequence and adjacent to the first sending period, the target bandwidth unit is located in a first carrier unit, the first carrier unit further carries the second type of data, and the target carrier unit is the first carrier unit or a second carrier unit.

In this embodiment, a first type of data is also carried on a first carrier unit carrying a second type of data, and the terminal device may obtain occupation indication information carried by the network side device on a target carrier unit in a first transmission period to determine a time-frequency resource occupied by the first type of data on a target bandwidth unit in which the terminal device is located in the first carrier unit in a second transmission period, and further determine a specific position of the first type of data on the first carrier unit so that the first type of data can be accurately removed and the second type of data can be demodulated The carrier unit and the second sending period of the occupation indication information are arranged before the first sending period adjacent to the carrier unit in time sequence, that is, the terminal device determines the occupation condition of the first type data of the previous sending period on the bandwidth unit which is operated by the terminal device according to the occupation indication information received in the next sending period, which not only can improve the success rate of data demodulation, but also can effectively optimize the information configuration mode of the occupation indication, reduce the probability of the false alarm indication and improve the performance of the system.

Further, the step of determining, according to the occupation indication information, the time-frequency resource occupied by the first type of data on the target bandwidth unit in the second sending period by the terminal device in step 504 of the foregoing embodiment is specifically executed as:

and acquiring bit information corresponding to the target bandwidth unit contained in the occupation indication information.

And when the terminal equipment does not jump to the bandwidth unit in the second sending period, determining the time-frequency resource occupied by the first type of data on the bandwidth unit in which the terminal equipment is located according to the bit information.

It can be understood that, if the terminal device always operates in one bandwidth unit of the first carrier unit in the second transmission period, the bit information corresponds to the time-frequency resource occupied by the first type of data in the one bandwidth unit; as shown in fig. 10, the 14 bits (i.e., bit information) of the occupancy indication information PI each correspond to a target bandwidth unit BWP2 of the terminal device UE1 in the carrier unit CC 1.

And when the terminal equipment jumps in the bandwidth unit in the second sending period, determining the time-frequency resources occupied by the first type of data in a plurality of bandwidth units in which the terminal equipment is positioned according to the bit information.

It can be understood that, if the terminal device skips the bandwidth unit in the second transmission period, that is, the terminal device has worked on multiple bandwidth units in the first carrier unit in the second transmission period, the bit information corresponds to the time-frequency resources occupied by the first type of data on the multiple bandwidth units; as shown in fig. 11, the 14 bits (i.e. bit information) of the occupancy indication information PI are divided into two parts, which respectively correspond to the target bandwidth units BWP2 and BWP3 of the terminal device UE1 in the carrier cell CC1, although the 14 bits of the occupancy indication information PI may or may not be divided equally.

In summary, the indication of the time-frequency resource occupied by the first type of data in the target bandwidth unit is performed according to the bit information included in the occupation indication information, so as to more effectively utilize the occupation indication bit resource in the DCI, and avoid the occurrence of false alarm indication caused by the terminal device jumping to the bandwidth unit.

Further, the data occupation indicating method in the above embodiment further includes: demodulating the second type of data which is loaded on the first carrier unit and punched by the first type of data according to the time-frequency resource; the first type of data is low-delay and high-reliability data, and the second type of data is enhanced mobile broadband data.

In this embodiment, the second type of data punctured by the first type of data can be accurately demodulated, where the first type of data is punctured and transmitted in the second type of data with completed resource configuration, so as to achieve fast delivery of the first type of data, where preferably the first type of data is low-latency high-reliability data with a higher requirement for latency and a higher resource scheduling priority, and the second type of data is preferably enhanced mobile broadband data with a higher throughput, so that a demodulation success rate of the enhanced mobile broadband data by the terminal device can be increased, and energy consumption of the terminal device receiving the enhanced mobile broadband data is reduced.

Further, in the above embodiments, the processor 604 is configured to implement the following operations when executing the computer program stored in the memory 606:

acquiring bit information corresponding to the target bandwidth unit contained in the occupation indication information; when the terminal equipment does not jump to the bandwidth unit in the second sending period, determining the time-frequency resource occupied by the first type of data on the bandwidth unit in which the terminal equipment is located according to the bit information; and when the terminal equipment jumps in the bandwidth unit in the second sending period, determining the time-frequency resources occupied by the first type of data in a plurality of bandwidth units in which the terminal equipment is positioned according to the bit information.

In this embodiment, the indication of the occupied time-frequency resource of the first type data on the target bandwidth unit is performed according to the bit information contained in the occupation indication information, to more effectively utilize the occupied indication bit resource in the DCI, specifically, if the terminal device always operates on one bandwidth unit in the first carrier unit in the second transmission period, the aforementioned bit information corresponds to the time-frequency resource occupied by the first type data in the bandwidth unit, and if the terminal device skips the bandwidth unit in the second transmission period, i.e. the terminal device has operated on a plurality of bandwidth units in the first carrier unit during the second transmission period, the aforementioned bit information corresponds to the time-frequency resources occupied by the first type of data over the plurality of bandwidth units, therefore, the situation that the terminal equipment skips the bandwidth unit where the terminal equipment is located to cause false alarm indication can be avoided.

Further, in the above embodiments, the processor 604 is configured to execute the computer program stored in the memory 606 to further implement the following operations:
