Patent Description:
In an LTE (Long-Term Evolution) system, during a process in which the base station performs the dynamic scheduling on the terminal, the terminal can detect scheduling signalings for itself on each downlink time domain unit. The number of detections supported by the terminal on each downlink time domain unit affects detection performance of the scheduling signalings and detection complexity of the terminal. The more the number of detections, the better the detection performance of the scheduling signalings, but the detection complexity and power consumption of the corresponding terminal will increase accordingly.

In a new generation of communication systems, control regions which is required to be detected by the terminal may be increased significantly, which will bring significant detection complexity to the terminal and cause greater power consumption.

<CIT> discloses a base station comprising a transmitter configured to transmit a downlink frame. The downlink frame comprises a resource allocation region, and the resource allocation region comprises a set of resource allocation messages comprising at least one resource allocation message. All or a subset of the resource allocation messages each comprise one or more fields with an indicator, interpreted from a particular field or a combination of some or all of the one or more fields, to indicate a number of resource allocation messages intended for a particular subscriber station in the resource allocation region.

In the related art, <FIG> shows a process in which the base station performs the dynamic scheduling of data transmission on the terminal. As illustrated in <FIG>, the scheduling signaling can schedule a data carrier for a time domain unit. For example, when the scheduling signaling is a downlink scheduling signaling, the terminal can schedule one time domain unit to receive data according to the signaling. Wherein, the time domain unit can be in units of OFDM (Orthogonal Frequency Division Multiplexing) symbols, slots, subframes, radio frames or the like.

In the related art, the terminal can perform up to <NUM> detections on each downlink time domain unit, for example, on a subframe. However, in the <NUM> system, once control intervals that the terminal needs to detect are significantly increased, the detection complexity is increased for the terminal, and greater power consumption is caused.

In the embodiment of the present disclosure, in order to effectively prevent the terminal from performing invalid detection on the useless scheduling signaling and save the power of the terminal, a method for detecting a scheduling signaling is provided, which is applicable to the base station, and includes the following steps.

In step <NUM>, the target information is sent to the terminal, wherein the target information is configured to determine whether a condition for stopping scheduling signaling detection on a current downlink time domain unit is satisfied, when the terminal performs the scheduling signaling detection on each downlink time domain unit.

In the above embodiment, the base station can send the target information to the terminal, and if the terminal performs the scheduling signaling detection on each downlink time domain unit, it is determined whether the condition for stopping the scheduling signaling detection on the current downlink time domain unit is satisfied. Through the foregoing process, the base station can send the target information to the terminal, the target information configured to determine the condition for stopping scheduling signaling detection, so that the terminal stops the scheduling signaling detection on the current downlink time domain unit, if the condition for stopping scheduling signaling detection is satisfied, so that in the dynamic scheduling process, the detection complexity of the terminal is reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved.

In an embodiment of the present disclosure, optionally, the base station can determine whether the terminal needs to receive or transmit data based on scheduling according to the current uplink and downlink service requirements of the terminal, and further transmit the target information to the terminal when determining that the terminal needs to receive or transmit data based on scheduling.

For example, for the terminal that supports a service type with a low latency requirement, the base station can perform scheduling-based data reception or transmission on the terminal, and can send target information to the terminal at this time, thereby reducing detection complexity for the terminal. wherein the target information includes any one of the following:.

The step <NUM> is described below for different target information.

In the first case, in accordance with the claims, the target information includes the maximum of the amount of the scheduling signalings transmitted on each downlink time domain unit.

In this case, the maximum of the amount of the scheduling signalings that can be transmitted on each downlink time domain unit such as each downlink subframe is taken as the target information configured to determine whether the condition for stopping the scheduling signaling detection is satisfied.

In step <NUM>, the base station can send the target information to the terminal through the first target signaling or the second target signaling.

Wherein, the first target signaling is a signaling sent to the terminal before sending the scheduling signaling. The first target signaling is an RRC (Radio Resource Control) signaling as claimed, or, not claimed: a system message, a MAC CE (MAC Control Element) or a physical layer signaling. That is, the base station can send the maximum of the amount of the scheduling signalings transmitted on each downlink time domain unit to the terminal before sending the scheduling signaling.

The second target signaling detection indication information can further include a third detection indication information configured to indicate currently remaining amount of scheduling signalings to be detected. Optionally, the second target signaling can be a common scheduling signaling for public information transmission, or an exclusive scheduling signaling corresponding only to the terminal, or a predefined signaling not belonging to the scheduling signaling. That is, the second target signaling can multiplex the scheduling signaling, for example, the second target signaling can be the common scheduling signaling or the exclusive scheduling signaling. The second target signaling may also not multiplex the scheduling signaling, but instead adopt a predefined individual signaling. However, the second target signaling and the scheduling signaling should belong to the same downlink time domain unit.

After the terminal receives the target information, if the amount of the scheduling signalings that have been detected on the current downlink time domain unit reaches the maximum, it is indicated that the terminal has detected all the scheduling signaling transmitted on the current downlink time domain unit, and it is determined that the condition for stopping the scheduling signaling detection is satisfied, thus it is not necessary to continue the scheduling signaling detection on the current downlink time domain unit.

In the second case, the target information includes the detection indication information configured to indicate whether to stop performing the scheduling signaling detection.

In the embodiment of the disclosure, the target information can be carried by the scheduling signaling, that is, the detection indication information can be carried in the scheduling signaling. Optionally, a region can be defined in the scheduling signaling, wherein the region is configured to carry the target information, that is, the detection indication information. Further, the target information can be located at a preset position of the scheduling signaling, and the target information can have a preset length. That is, the detection indication information can be located at a preset position of the scheduling signaling and have the preset length.

Optionally, the detection indication information can include a first detection indication information configured to indicate continuing the scheduling signaling detection, and a second detection indication information configured to indicate stopping the scheduling signaling detection.

At this time, the detection indication information can adopt different preset values to indicate whether it is necessary to continue the scheduling signaling detection. For example, the detection indication information can occupy a length of <NUM> bit, and the value of the first detection indication information can be <NUM> which indicates continuing the scheduling signaling detection; the value of the second detection indication information can be <NUM>, which indicates stopping the scheduling signaling detection.

In step <NUM>, the base station can send the detection indication information carried in the scheduling signaling to the terminal.

Of course, in the embodiment of the present disclosure, the first detection indication information and the second detection indication information can be configured to indicate whether it is necessary to perform the scheduling signaling detection on the current downlink time domain unit, and can further be configured to indicate whether it is necessary to continue to perform the scheduling signaling detection on the subsequent downlink time domain unit.

Alternatively, in the embodiment of the present disclosure, the detection indication information can further include a third detection indication information configured to indicate currently remaining amount of scheduling signalings to be detected.

At this time, the scheduling signalings can be arranged in sequence. The base station can add the third detection indication information to a preset location corresponding to each scheduling signaling. The third detection indication information is configured to indicate the currently remaining amount of the scheduling signalings to be detected.

For example, the third detection indication information may be respectively added to the N scheduling signalings arranged in sequence, and the third detection indication information respectively corresponds to the number N-<NUM>, N-<NUM>,. <NUM> of the currently remaining amount of the scheduling signalings to be detected.

In the step <NUM>, the base station can carry the third detection indication information in the scheduling signalings, and send the third detection indication information to the terminal while sending the scheduling signalings. After receiving the scheduling signalings, the terminal can determine whether the condition for stopping the scheduling signaling detection is satisfied according to the value of the corresponding detection indication information in the scheduling signalings. If the value indicated by the third detection indication information carried in the scheduling signalings is <NUM>, the terminal determines that the condition for stopping the scheduling signaling detection is satisfied.

In a third case, the target information includes the feature information configured to indicate whether to stop performing the scheduling signaling detection.

Optionally, the feature information can include: a first preset scrambling sequence and a second preset scrambling sequence configured to scramble downlink control information; wherein, the first preset scrambling sequence is configured to indicate continuing the scheduling signaling detection, and the second preset scrambling sequence is configured to indicate stopping the scheduling signaling detection.

In the embodiment of the present disclosure, two preset scrambling sequences can be provided, wherein the first preset scrambling sequence is configured to indicate continuing the scheduling signaling detection, and the second preset scrambling sequence is configured to indicate stopping the scheduling signaling detection. Different scheduling signalings can be scrambled through the preset scrambling sequence.

In the step <NUM>, after the scheduling signalings are scrambled through the target information, the scrambled scheduling signalings can be sent to the terminal. After the scrambled scheduling signalings are received by the terminal, the scrambled scheduling signalings can be descrambled through the preset scrambling sequence. If the scheduling signalings are successfully descrambled through the second preset scrambling sequence, it can be determined that the condition for stopping the scheduling signaling detection is satisfied.

In the embodiment of the present disclosure, optionally, a plurality of preset scrambling sequences can be further provided, which respectively correspond to currently remaining amount of scheduling signalings to be detected. The scheduling signalings are scrambled by a plurality of preset scrambling sequences and then sent to the terminal. After the scrambled scheduling signalings are received by the terminal, the scheduling signalings are descrambled by a plurality of preset scrambling sequences. If the scheduling signalings are successfully descrambled by the preset scrambling sequence, it can be determined that the condition for stopping the scheduling signaling detection is satisfied, wherein the currently remaining amount of scheduling signalings to be detected corresponding to the target preset scrambling sequence is zero.

The embodiment of the present disclosure provides another method for detecting a scheduling signaling, which can be applicable to a terminal. Referring to <FIG> is another method for detecting a scheduling signaling according to an embodiment, including the following steps:.

In step <NUM>, the target information sent by the base station is received; wherein the target information is configured to determine whether a condition for stopping scheduling signaling detection on a current downlink time domain unit is satisfied, when the terminal performs the scheduling signaling detection on each downlink time domain unit;.

In step <NUM>, when the scheduling signaling detection is performed on each downlink time domain unit, if it is determined that the condition for stopping the scheduling signaling detection is satisfied according to the target information, the scheduling signaling detection on the current downlink time domain unit is stopped.

In the above embodiment, when the terminal performs the scheduling signaling detection on each downlink time domain unit sent by the base station after receiving the target information sent by the base station, it can determine whether the condition for stopping the scheduling signaling detection is satisfied according to the target information. If the condition for stopping the scheduling signaling detection is satisfied, the terminal stops performing the scheduling signaling detection on the current downlink time domain unit. Through the above process, during the dynamic scheduling, the invalid scheduling signaling detection performed by the terminal can be effectively avoided, the detection complexity of the terminal is reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved.

For the above step <NUM>, the base station can send any one of the target information to the terminal through the above method, and the terminal can directly receive it according to the related art.

For the above step <NUM>, in the related art, the terminal can search for the corresponding DCI formats (Downlink Control Information Format) according to the transmission mode supported by the terminal in the search space where the downlink control information is located, thereby implementing the scheduling signaling detection.

In this step, the terminal can perform the scheduling signaling detection on each downlink time domain unit according to the above related art. In the detection process, if it is determined that the condition for stopping the scheduling signaling detection is satisfied, the scheduling signaling detection on the current downlink time domain unit is stopped.

If, in accordance with the claims, the target information includes the maximum of the amount of the scheduling signalings transmitted on each downlink time domain unit, the terminal needs to determine whether amount of the scheduling signalings that have been detected on the current downlink time domain unit reaches the maximum. If the amount of the scheduling signalings that have been detected on the current downlink time domain unit reaches the maximum, then even if the scheduling signaling detection is continued, no scheduling signaling can be detected. In order to effectively avoid invalid scheduling signaling detection, it can be determined that the condition for stopping the scheduling signaling detection is satisfied.

The detection indication information includes a first detection indication information configured to indicate continuing the scheduling signaling detection, and a second detection indication information configured to indicate stopping the scheduling signaling detection. When the second detection indication information can be detected in the current downlink time domain unit by the terminal, it can be determined that the condition for stopping the scheduling signaling detection is satisfied.

The target information includes a third detection indication information configured to indicate a currently remaining amount of scheduling signalings to be detected. When the third detection indication information is detected by the terminal on the current downlink time domain unit, and the currently remaining amount of the scheduling signalings to be detected indicated by the third detection indication information is zero, it can be determined that the terminal has detected all the scheduling signaling transmitted on the current downlink time domain unit, and it can be determined that the condition for stopping the scheduling signaling detection is satisfied.

When the target information includes a first preset scrambling sequence and a second preset scrambling sequence configured to scrambling downlink control information, the terminal may attempt to descramble the scheduling signaling through the first preset scrambling sequence and the second preset scrambling sequence respectively. If the scheduling signaling is descrambled through the second preset scrambling sequence, it can be determined that the condition for stopping the scheduling signaling detection is satisfied.

Or, the target information can further include a plurality of preset scrambling sequences corresponding to the currently remaining amount of scheduling signalings to be detected. If the terminal descrambles the scheduling signaling through the target preset scrambling sequence, the terminal can determine that the condition for stopping the scheduling signaling detection is satisfied. The target preset scrambling sequence is a preset scrambling sequence corresponding to the currently remaining amount of scheduling signalings to be detected.

Through the above process, when the condition for stopping the scheduling signaling detection is satisfied, the scheduling signaling detection on the current downlink time domain unit will be stopped, so that in the dynamic scheduling process, the detection complexity of the terminal is reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved.

In an embodiment, referring to <FIG> is a flowchart of another method for detecting a scheduling signaling on the basis of the embodiment illustrated in <FIG>, further including:.

in step <NUM>, if it is determined that the condition for stopping the scheduling signaling detection is not satisfied according to the target information, and the amount of the scheduling signaling detection on the current downlink time domain unit has not reached a preset maximum corresponding to the terminal, the scheduling signaling detection on the current downlink time domain unit continues.

In this step, if it is determined that the condition for stopping the scheduling signaling detection is not satisfied according to the target information, and the amount of the scheduling signaling detection on the current downlink time domain unit has not reached a preset maximum corresponding to the terminal, the terminal can continue to perform the scheduling signaling detection on the current downlink time domain unit according to the related art.

In the foregoing embodiment, in a process in which the base station performs the dynamic scheduling on the terminal, if it is determined that the condition for stopping the scheduling signaling detection is not satisfied according to the target information sent by the base station, the scheduling signaling detection on the current downlink time domain unit can be continued; if it is determined that the condition for stopping the scheduling signaling detection is satisfied according to the target information, the scheduling signaling detection on the current downlink time domain unit will be stopped immediately. The complexity of the scheduling signaling detection is effectively reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved.

Referring to <FIG> is a method for detecting a scheduling signaling according to another embodiment, including the following steps:
in step <NUM>, the base station sends the target information to the terminal through the first target signaling or the second target signaling.

Wherein the target information includes a maximum of the amount of the scheduling signalings transmitted on each downlink time domain unit.

In step <NUM>, the terminal performs the scheduling signaling detection on each downlink time domain unit.

In step <NUM>, the terminal determines whether the amount of the scheduling signalings that have been detected on the current downlink time domain unit reaches the maximum.

If the amount of the scheduling signalings that have been detected on the current downlink time domain unit reaches the maximum, the step <NUM> is performed, and if the number does not reach the maximum, then then step <NUM> is performed.

In step <NUM>, the terminal determines that the condition for stopping the scheduling signaling detection is satisfied, and the scheduling signaling detection on the current downlink time domain unit is stopped.

Of course, in the above embodiment, the amount of the scheduling signaling detection on the current downlink time domain unit does not reach the preset detection amount.

The foregoing process is further illustrated in <FIG>. The base station can send the maximum to the terminal through the first target signaling. For example, the downlink control region on one slot includes <NUM> OFDM symbols, and the maximum of the scheduling signalings transmitted on one slot is <NUM>, and the terminal has detected <NUM> scheduling signalings on the OFDM symbol <NUM>. Then, the terminal can determine that the condition for stopping the scheduling signaling detection is satisfied, and the scheduling signaling detection on the current slot is stopped. That is, there is no need to detect the scheduling signaling on the OFDM symbol <NUM>.

In the above embodiment, the target information that is sent by the base station to the terminal can include a maximum of the number of the scheduling signalings transmitted on each downlink time domain unit; or detection indication information configured to indicate whether to stop scheduling signaling detection; or feature information configured to characterize whether to stop scheduling signaling detection. Through the target information sent by the base station, the terminal is allowed to quickly determine whether the condition for stopping scheduling signaling detection is satisfied with high availability.

Wherein, the target information includes the detection indication information configured to indicate whether to stop the scheduling signaling detection. Optionally, the detection indication information may include a first detection indication information configured to indicate continuing the scheduling signaling detection, and a second detection indication information configured to indicate stopping the scheduling signaling detection.

When the second detection indication information is detected upon the terminal detects the current downlink time domain unit, the step <NUM> is performed, and if the first detection indication information is detected, the step <NUM> is continued.

The foregoing process is further illustrated in <FIG>. The base station can send the scheduling signalings carrying the target information to the terminal. For example, if the terminal detects the first detection indication information (that is, the detection indication information with the value of <NUM>) in the downlink control region <NUM> on a certain slot, the terminal continues to perform the scheduling signaling detection on the downlink control region <NUM>. If the second detection indication information ((that is, the detection indication information with the value of <NUM>), that is, the detection indication information whose value is <NUM>, the terminal stops performing the scheduling signaling detection on the downlink control region <NUM>.

In the foregoing embodiment, the detection indication information further includes a third detection indication information configured to indicate the currently remaining amount of scheduling signalings to be detected. If the terminal detects the third detection indication information with the value of <NUM> in the downlink control region <NUM>, it is determined that the condition for stopping the scheduling signaling detection is satisfied, and there is no need to perform the scheduling signaling detection on the downlink control region <NUM>. Otherwise, the terminal still needs to perform the scheduling signaling detection on the downlink control region <NUM>.

In the above embodiment, the target information can further include the detection indication information. Optionally, the detection indication information includes a first detection indication information configured to indicate that the scheduling signaling detection needs to be continued, and a second detection indication information configured to indicate stopping the scheduling signaling detection. Or the detection indication information can further include a third detection indication information configured to indicate the currently remaining amount of scheduling signalings to be detected. The base station can send the scheduling signalings carrying the target information to the terminal. When the terminal detects the second detection indication information, or detects the third detection indication information, and the currently remaining amount of the scheduling signalings to be detected indicated by the third detection indication information is zero, it can be determined that the condition for stopping the scheduling signaling detection is satisfied. The following purposes are realized: the detection complexity of the terminal is reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved during the dynamic scheduling.

In step <NUM>, the base station scrambles the scheduling signalings through the target information.

wherein the target information includes the feature information configured to characterize whether to stop scheduling signaling detection. Optionally, the feature information includes a first preset scrambling sequence and a second preset scrambling sequence for scrambling downlink control information; wherein, the first preset scrambling sequence is configured to indicate continuing the scheduling signaling detection, and the second preset scrambling sequence is configured to indicate stopping the scheduling signaling detection.

In step <NUM>, the base station sends the scrambled scheduling signalings to the terminal.

After the terminal descrambles the scheduling signalings on the current downlink time domain unit through the second preset scrambling sequence, the step <NUM> is performed. If the scheduling signalings are descrambled through the first preset scrambling sequence, the step <NUM> is performed.

In the embodiment of the disclosure, the target information can also be a plurality of preset scrambling sequences, which respectively correspond to currently remaining amount of scheduling signalings to be detected. The scheduling signalings are scrambled by a plurality of preset scrambling sequences and then sent to the terminal. After the scrambled scheduling signalings are received by the terminal, the scheduling signalings are descrambled through a plurality of preset scrambling sequences. If the scheduling signalings are successfully descrambled through the target preset scrambling sequence, it can be determined that the condition for stopping the scheduling signaling detection is satisfied. Wherein, the currently remaining amount of scheduling signalings to be detected corresponding to the target preset scrambling sequence is zero.

In the above embodiment, the target information can further include feature information. The base station can send the scrambled scheduling signalings to the terminal, after the scheduling signalings are scrambled through the target information. On the terminal side, if the scheduling signalings are descrambled through the second preset scrambling sequence configured to indicate stopping the scheduling signaling detection, it can be determined that the condition for stopping the scheduling signaling detection is satisfied. The following purposes are realized: the detection complexity of the terminal is reduced, the power consumption of the terminal is reduced, and the power of the terminal is saved during the dynamic scheduling.
