Description

Information processing method, device, base station, terminal and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, a base station, a terminal, and a storage medium.

Background

In the new generation of wireless communication technology, an important feature is the flexible configuration that supports multiple service types. Because different service types have different requirements for wireless communication technology, for example, the main requirements of the mobile bandwidth enhanced (eMBB) service type focus on the aspects of large bandwidth, high rate and the like; ultra-high-reliability and low-Latency Communications (URLLC) service types mainly require emphasis on higher reliability and low Latency; the major requirements of large-scale internet of things (mtc) traffic types focus on large connection numbers. New generation wireless communication technologies therefore require flexible and configurable designs to support the transmission of multiple traffic types.

In recent years, with the vigorous development of the technology of the internet of things, a large number of new applications are generated. For example, some sensor applications in industrial internet of things, wireless video monitoring in smart cities, and wearable devices such as bracelets, watches, and health medical monitoring devices, etc. are included.

In some application scenarios, there may be a large number of connected terminals in the system, however, the service characteristics of the large number of terminals are relatively similar and the data size is relatively small. In this case, if a conventional method of scheduling data transmission for each terminal using independent scheduling signaling is used, a large amount of control signaling overhead is caused.

As shown in fig. 2, an embodiment of the present disclosure provides an information processing method, including the following steps:

step S21: and sending a group scheduling signaling, wherein the group scheduling signaling is used for scheduling data transmission of a plurality of terminals in one terminal group.

The information processing method in the embodiment of the disclosure is applied to a base station. Here, the base station is an interface device for the user equipment to access the internet. The base station may be various types of base stations, such as a 3G base station, a 4G base station, a 5G base station, or other evolved node base station.

Here, the terminal may be a mobile phone, a computer, a server, a transceiving device, a tablet device, or a medical device, etc.

In some application scenarios, a plurality of terminals of the one terminal group satisfy a certain similarity.

Here, the similarity includes, but is not limited to, at least one of: channel similarity, capability similarity, and traffic feature similarity.

Here, the channel similarity may be: the channel state parameters of the terminal are within a predetermined range. If the channel state parameter is the signal-to-noise ratio, the terminal 1 and the terminal 2 satisfy the following channel similarity: the difference between the signal-to-noise ratios of the terminal 1 and the terminal 2 is smaller than a predetermined signal-to-noise ratio threshold. Of course, the channel state parameter may also be other parameters indicating the channel condition, such as bandwidth, etc.

Here, the capability similarity may be: the terminal capability parameter of the terminal is within a predetermined range. If the terminal capability parameter is data processing delay, the terminal 1 and the terminal 2 satisfy the capability similarity as follows: and the difference between the data processing time delays of the terminal 1 and the terminal 2 is less than a preset time threshold. Of course, the terminal capability parameter may also be a parameter of other terminal capabilities, such as MIMO capability supported by the terminal.

Here, the service feature similarity may be: the service characteristics of the terminals are similar. If the service characteristics of the terminal 1 and the terminal 2 are similar: the arrival time of the service of the terminal 1 and the terminal 2 is within the predetermined time threshold range, and/or the end time of the service of the terminal 1 and the terminal 2 is within the predetermined time threshold range. As another example, the service characteristics of the terminal 1 and the terminal 2 are similar, and the service distribution is similar.

In an embodiment, a plurality of terminals whose channel states satisfy channel similarity are located in the same terminal group.

In this embodiment, a base station triggers a plurality of terminals to report channel state parameters; the base station receives channel state parameters reported by a plurality of terminals; the base station allocates a plurality of terminals of which the channel states satisfy the channel similarity to a terminal Group, and allocates corresponding Group identification information (Group ID, GI) to the terminal Group.

In another embodiment, a plurality of terminals whose terminal capabilities satisfy the capability similarity are located in the same terminal group.

In this embodiment, a base station receives terminal capability parameters reported by a plurality of terminals; and the base station allocates a plurality of terminals with the terminal capability meeting the similarity to one terminal group and allocates corresponding group identification information to the terminal group.

In a further embodiment, a plurality of terminals whose service features satisfy the service feature similarity are located in the same terminal group.

In this embodiment, a base station receives service characteristic information reported by a plurality of terminals; and the base station allocates a plurality of terminals with service characteristics meeting the service characteristic similarity into a terminal group and allocates corresponding group identification information to the terminals.

As such, in the embodiments of the present disclosure, a plurality of terminals similar in channel condition, or terminal capability or traffic characteristics of transmission data may be allocated as one terminal group. In this way, group scheduling signaling can be transmitted for a plurality of terminals supporting multicast scheduling.

Of course, in other application scenarios, the data amount of the data transmitted by the plurality of terminals grouped by one terminal is less than the predetermined bit number. In this way, in the embodiment of the present disclosure, terminals whose data volume of transmission data is smaller than a certain number of bits may be allocated in one terminal group.

As shown in fig. 3, in some embodiments, the method further comprises:

step S20: sending grouping information of a terminal to the terminal;

the step S21 includes:

step S211: and sending a group scheduling signaling according to the grouping information.

Here, the grouping information is used to indicate a terminal group to which the terminal belongs. Here, the grouping information may be determined based on one of a channel state parameter, a terminal capability parameter, and traffic characteristic information.

In one embodiment, the grouping information includes: group identification information.

In another embodiment, the grouping information includes: group identification information and the number of terminals.

In an embodiment of the present disclosure, one implementation manner of the step S20 is: and sending the group identification information of the terminal to the terminal.

In an embodiment of the present disclosure, one implementation manner of step S211 is: and sending the group scheduling signaling carrying the group identification information.

In some embodiments, the step S20 includes:

alternatively, the first and second electrodes may be,

Here, the higher layer information order includes: radio Resource Control (RRC) signaling, or Media Access Control (MAC) signaling.

Here, the physical layer signaling includes: and (6) DCI.

In the embodiment of the present disclosure, the base station may send a corresponding group scheduling signaling to the terminal based on the grouping information; therefore, the probability of group scheduling signaling missending can be reduced, and the success rate of scheduling terminal data transmission is favorably improved.

In addition, in the embodiment of the present disclosure, the grouping information of the terminal may also be sent to the terminal in advance. When the terminal receives a group scheduling signaling sent based on the grouping information, detecting whether the group scheduling signaling is the group scheduling signaling for the terminal; and if so, transmitting data based on the group scheduling signaling.

Here, one way to detect whether the group scheduling signaling is the group scheduling signaling for itself is as follows: and determining whether the group identification information carried in the group scheduling signaling is the group identification information of the terminal, if so, determining the group scheduling signaling as the group scheduling signaling for the group scheduling signaling.

In addition, in the embodiments of the present disclosure, various ways of sending packet information are also provided, for example, the packet information is sent to a corresponding terminal through higher layer signaling or physical layer signaling.

As shown in fig. 4, in some embodiments, the step S21 includes:

step S212: sending DCI (downlink control information) for bearing the group scheduling signaling;

In one embodiment, the step S212 includes: and sending a downlink control information DCI for bearing the group scheduling signaling.

Here, the grouping information field is a fixed information field or a dynamically configured information field in the DCI.

Here, the fixed information field is an information field with a fixed position and/or a fixed length.

For example, in an embodiment, the DCI occupies N bits, and the N bits are numbered 1 st to N once; the packet information field may be the bit occupying the numbers O to P in the N bits; wherein N > P > O >1, N, P, and O are positive integers. Here, O and P are fixed values set. As such, the packet information field is located at a fixed location of the DCI.

For another example, in the above example, if N is 6, O is 2, and P is 4, the packet information field occupies 3 bits numbered from 2 to 4. Thus, the packet information field is located in a fixed-length information field of the DCI.

Thus, in this embodiment, if the terminal receives the group scheduling signaling, the group information may be detected based on the DCI fixed position and/or the fixed length, which is beneficial for the terminal to quickly find the group information.

Here, the dynamically configured information field may be an information field whose position and/or length dynamically changes.

For example, in the above example, the base station configures the packet field to occupy bits encoded as H to L among the N bits; wherein N > H > L >1, and H and L are positive integers. Here, H and L may be any number of bits configured by the base station. In this way, the grouping information field may be located at any position of the DCI, and the grouping information field may occupy any number of bits of the DCI.

Thus, the grouping information can be carried in any unoccupied position in the DCI, so that the base station can more flexibly configure the group scheduling signaling; and the influence of the grouping information on the scheduling information in the group scheduling signaling can be greatly reduced.

In some embodiments, the group scheduling signaling further comprises: a resource location field; and the resource location domain carries resource information for data transmission.

Here, the resource location field is a fixed information field or a dynamically configured information field in the DCI.

Here, the resource location field is the DCI internal fixed information field or the dynamically configured information field, and similar to the description that the grouping information field is the DCI internal fixed information field or the dynamically configured information field, it is only required to satisfy that the grouping information field and the resource location field are different in location on the DCI.

In an embodiment, the packet information field carries group identification information of the terminal packet for scheduled data transmission.

In an embodiment, the resource location field carries resource information of data transmission of the terminal packet.

For example, the terminals are grouped into 2 terminals, and the resource location domain carries resource information of data transmission of the 2 terminals. In this way, the terminal receiving the group scheduling signaling can know the resource information allocated to the terminal group by the base station.

In another embodiment, the resource location field carries resource information of data transmission of the terminal group and resource information of data transmission of each terminal in the terminal group.

For example, the terminals are grouped into 2 terminals, and the 2 terminals are terminal 1 and terminal 2 respectively; the resource location domain carries the resource information of the data transmission of the 2 terminals, and the resource information of the data transmission corresponding to the terminal 1 and the terminal 2 respectively. Thus, after terminal 1 or terminal 2 receives the group scheduling signaling, it can know the resource information allocated to the terminal group by the base station and the resource information corresponding to itself.

In one embodiment, the resource information includes: frequency domain location information.

In the embodiment of the present disclosure, the group scheduling signaling may be sent to a plurality of terminals in a corresponding terminal group based on the DCI bearer group scheduling signaling. Wherein, one information field of the DCI may be a packet information field, and is configured to carry the packet information. Thus, when the terminal in the terminal group receives the group scheduling signaling, the terminal is favorable for determining whether the group scheduling signaling is directed to the self scheduling.

In addition, in this embodiment of the present disclosure, another information field of the DCI may be a resource location field, and is configured to carry resource information of the data transmission. Therefore, when the terminal in the terminal group receives the group scheduling signaling, the terminal is favorable for carrying out data transmission based on the resource information carried in the resource location domain.

And, in the embodiment of the present disclosure, the packet information or the resource information is carried in one DCI to be transmitted; therefore, the terminal does not need to use extra signaling to inform whether the group scheduling signaling is the resource information used for scheduling the terminal or sending data transmission, and the signaling overhead can be further reduced.

In some embodiments, the method further comprises: issuing the number of terminals (Group Size, GS) in a Group where the terminals scheduled for data transmission are located;

alternatively, the first and second electrodes may be,

In an embodiment, a resource location (Scheduled ID, SI) of each of the terminals within the terminal group is contiguous.

For example, in an application scenario, as shown in fig. 5, the number of frequency domain resources allocated to group 1 by the base station is 10 RBs. If group 1 includes 5 terminals, the 5 terminals are respectively: UE1, UE2, UE3, UE4, and UE 5. In this example, the base station allocates 2 consecutive RBs to each of UE1, UE2, UE3, UE4, and UE 5.

For another example, in another application scenario, as shown in fig. 6, the number of frequency domain resources allocated to group 1 by the base station is 10 RBs. If group 1 includes 2 terminals, the 2 terminals are respectively: UE1, and UE 2. In this example, the base station allocated 5 consecutive RBs to both UE1 and UE 2.

In another embodiment, the resource location of each of the terminals within the terminal group is non-contiguous.

For example, in an application scenario, as shown in fig. 7, the number of frequency domain resources allocated to group 1 by the base station is 10 RBs. If group 1 includes 5 terminals, the 5 terminals are respectively: UE1, UE2, UE3, UE4, and UE 5. In this example, the base station allocates 2 non-consecutive RBs to each of UE1, UE2, UE3, UE4, and UE 5.

For another example, in another application scenario, as shown in fig. 8, the number of frequency domain resources allocated to group 1 by the base station is 10 RBs. If group 1 includes 2 terminals, the 2 terminals are respectively: UE1, and UE 2. In this example, the base station allocated 5 non-consecutive RBs to both UE1 and UE 2.

In one embodiment, the number of resources for each of the terminals in the terminal group is evenly distributed.

For example, in the examples shown in fig. 5 and 7, the number of resources per terminal of 5 terminals in group 1 is evenly distributed, with 2 RBs being distributed.

As another example, in the examples shown in fig. 6 and 8, the number of resources per terminal of the 2 terminals in group 1 is evenly allocated, with 5 RBs being allocated.

In another embodiment, the number of resources per said terminal within said terminal group is not evenly distributed.

For example, in an application scenario, as shown in fig. 9, the number of frequency domain resources allocated to group 1 by the base station is 10 RBs. If group 1 includes 5 terminals, the 5 terminals are respectively: UE1, UE2, UE3, UE4, and UE 5. In this example, the RBs allocated by the base station to UE1, UE2, UE3, UE4, and UE5 are not evenly allocated; wherein 2 RBs are allocated to UE1, 1 RB is allocated to both UE2 and UE5, and 3 RBs are allocated to both UE3 and UE 4.

In yet another embodiment, the location of the resource scheduled by each of the terminals within the terminal group at a time is dynamically changed.

For example, the base station determines the resource location of each terminal in the current multicast scheduling based on a predetermined algorithm.

In practical application, the base station obtains a time domain unit serial number bearing the multicast scheduling and/or a network temporary identifier (RNTI) of the terminal; inputting the time domain unit serial number and/or the network temporary identifier into a preset algorithm model for calculation; and determining the SI of the terminal based on the output result of the predetermined algorithm model.

Thus, the present embodiment can dynamically and flexibly allocate resource locations required by the terminal according to the specific situation that the terminal is scheduled each time.
