Detailed ways

If there is a scheduling conflict between the dynamic scheduling and the semi-persistent scheduling for the same scheduling time domain unit, the work of the UE may be confused, or the semi-persistent scheduling data cannot be transmitted after the semi-persistent scheduling is conflicted, or the semi-persistent scheduling may not be transmitted. Continuous scheduling needs to be reset. The scheduling time domain unit may be a frame, a subframe, or a time slot, or the like. In view of this, as shown in FIG. 1 , this embodiment provides a semi-persistent scheduling data transmission method, which is applied to a communication device. The communication device may be a base station or a UE. If the communication device is a base station, the transmission of the semi-persistent scheduling data is the transmission of the semi-persistent scheduling data in the uplink direction; if the communication device is the UE, the transmission of the semi-persistent scheduling data is the transmission of the semi-persistent scheduling data in the downlink direction. transmission. The transmission of the semi-persistent scheduling data includes:

Step S100: Acquire a configured transmission time window of semi-persistent scheduling, wherein the transmission time window includes: a plurality of transmission units;

Step S200: According to the acquired control information of the physical control channel, one or more of the transmission units selected within the transmission time window perform semi-persistent scheduling data transmission.

The physical control channel here may include: a first physical control channel and/or a second physical control channel. In some implementations, the physical control channel may further include other control channels than the first physical control channel and the second physical control channel.

If the current execution subject of steps S100 to S200 is the base station, in step S100 the base station reads the locally configured transmission time window attribute parameters to obtain the configured semi-persistent scheduling transmission time window. In step S200, the base station may read the locally generated control information of the first physical control channel and/or the second physical control channel, and select one or more transmission units within the transmission time window to transmit downlink semi-persistent scheduling data .

When the execution subject currently executing steps S100 to S200 is the UE, in step S100, the UE receives the attribute parameters of the transmission time window sent by the base station, for example, receiving broadcast system messages, or information such as radio resource control information to obtain The configured transmission time window for semi-persistent scheduling. In step S200, the UE may select one or more transmission units within the transmission time window to transmit downlink semi-persistent scheduling data by monitoring the control information of the first physical control channel and/or the second physical control channel.

For the UE to monitor the first physical control channel and/or the second physical control channel, it may include: entering a semi-continuous reception (DRX) activation before or at the time domain start position corresponding to the transmission time window state; after entering the DRX active state, monitor the first physical control channel and the second physical control channel to obtain the first physical control channel and/or the second physical control channel.

In this embodiment, the first physical control channel and the second physical control channel may be scheduling signaling in which the transmission priority of data such as dynamically scheduled control information is higher than the priority of semi-persistent scheduling.

In this embodiment, the first physical control channel and the second physical control channel may be different types of control channels. E.g,

The first physical control channel is: a control channel used to send a control channel to a group of user equipment UEs;

The second physical control channel is: a control channel used for sending control information to a single user equipment UE.

The first physical control channel may be a control channel for a group of UEs, and may generally be used to transmit control information of a transmission format such as dynamic scheduling, whose transmission priority is higher than that of semi-persistent scheduling data. The second physical control channel may be a control channel signaling for a single user, transmitted to a specific UE through unicast, indicating that it transmits specific data.

For example, the first physical control channel may be a group common physical downlink control channel (group common Physical Downlink Control Channel, group common PDCCH); the second physical control channel may be a user equipment dedicated physical downlink control channel (UE specific Physical Downlink Control Channel). Downlink Control Channel, UE specific PDCCH) can be used for dynamic scheduling.

The control information of the group common PDCCH may carry relevant information indicating a transmission format of a scheduling unit provided by a group of user equipments, and the scheduling unit here may be a frame, a subframe, or a time slot.

The control information of the UE specific PDCCH may carry dynamic scheduling information for the specific UE, and the dynamic scheduling information directly instructs the corresponding UE to perform uplink transmission or downlink reception.

The semi-persistent scheduling data is data transmitted by using semi-persistent scheduling resources.

The transmission time window includes: at least two transmission units. Optionally, the number of transmission units included in the transmission time window is greater than the number of transmission units required for one semi-persistent scheduling data transmission.

For example, if the semi-persistent scheduling is used once, s1 transmission units need to be consumed, then in this embodiment, the number of transmission units included in the transmission time window is greater than the s1.

In other embodiments, the plurality of transmission units included in the transmission unit are continuously distributed in the time domain, or may be discretely distributed, and may optionally be continuously distributed in the time domain, so as to improve the response of semi-persistent scheduling as much as possible rate. The transmission unit included in the transmission time window in this embodiment may be: a time domain resource set that can be used for semi-persistent scheduling data transmission.

In this embodiment, a transmission time window is introduced, and the transmission time window includes at least two transmission units. The data to be transmitted in the semi-persistent scheduling (that is, the semi-persistent scheduling data) can be selected from any one or more of these transmission time windows. The transmission unit is no longer limited to the semi-persistent scheduling unit that only instructs one transmission unit to transmit. Once the transmission unit is collided or delayed, the semi-persistent scheduling data has to be delayed or not transmitted. The flexibility and transmission success rate of semi-persistent scheduling transmission are improved, and the problem of repeated scheduling is reduced. The transmission of the semi-persistent scheduling data here may be uplink transmission and/or downlink transmission.

High transmission priority data such as dynamic scheduling (here, high transmission priority data specifically refers to data whose transmission priority is higher than that of semi-persistent scheduling data, such as dynamic scheduling data) and transmission conflicts between semi-persistent scheduling data It can be reflected in two levels:

At the first level, there is a scheduling collision between high transmission priority data and semi-persistent scheduling, and the transmission direction of the scheduling is inconsistent. For example, dynamic scheduling schedules the mth transmission unit for uplink transmission, while semi-persistent scheduling needs to use the mth transmission unit. Downlink transmission. In this way, not only the two scheduling types need to occupy the transmission unit, but also the transmission directions of the transmission units are configured as different transmission directions. For example, in some transmission scenarios, there may be multiple transmission formats for a scheduled time-domain unit. For example, in 5G scenarios. The transmission formats include: an uplink transmission format for all uplink transmissions, a downlink transmission format for all downlink transmissions, and a mixed transmission format including both uplink and downlink.

For example, if a scheduling time domain unit is a frame, the frame may be an uplink transmission frame, a downlink transmission frame and a mixed transmission frame. The transmission format corresponding to the uplink transmission frame is: the transmission direction of each transmission unit in the uplink transmission frame is the uplink direction. The transmission format corresponding to the downlink transmission frame is: the transmission direction of each transmission unit in the downlink transmission frame is the downlink direction. The transmission format corresponding to the hybrid transmission frame is: some transmission units are in the uplink direction, and another part of the transmission units are in the downlink direction. The downlink direction is: the direction from the base station to the UE. The uplink direction is: the direction from the UE to the base station.

At the second level, high transmission priority data and semi-persistent scheduling both schedule the same transmission unit, resulting in scheduling collision. For example, high transmission priority data needs to use the mth transmission unit to transmit dynamic scheduling data, and semi-persistent scheduling needs to use the mth transmission unit to transmit semi-persistent scheduling data.

The high transmission priority data and semi-persistent scheduling data here are service data scheduled for transmission in a corresponding scheduling manner, and may include uplink data and/or downlink data.

The specific length of the time domain resource corresponding to the transmission unit may be determined according to the scheduling time domain unit. For example, if a time slot is scheduled, the time slot may also include the aforementioned three transmission formats, and the transmission unit may be a mini-slot or a transmission symbol. In this case, the transmission format of each transmission slot may be indeterminate, and the transmission direction of each transmission unit in each transmission slot may be indeterminate. In this case, the method provided in this embodiment resolves conflicts at two levels respectively based on the scheduling priority.

As shown in FIG. 2, the step S200 may include:

Step S201: Determine the transmission direction of at least one of the transmission units and/or at least one transmission sub-unit in at least one of the transmission units in the transmission time window according to the acquired control information of the physical control channel; wherein, the transmission The directions include: the upward direction and the downward direction;

Step S202: Select a transmission unit or a transmission sub-unit whose transmission direction is consistent with the transmission direction of the semi-persistent scheduling data to be transmitted within the transmission time window, and transmit the semi-persistent scheduling data.

Therefore, in this embodiment, the transmission direction of one or more transmission units and/or one or more transmission sub-units in at least one transmission unit within the transmission time is first determined, and then the transmission direction of the semi-persistent scheduling data is selected. Coherent transmission units or transmission sub-units perform semi-persistently scheduled data transmission.

Of course, only when there is semi-persistent scheduling data that needs to be transmitted in the transmission unit, it is necessary to combine the control channel signaling and use the transmission unit of the transmission time window to transmit dynamic scheduling data or semi-persistent scheduling data; otherwise, the UE can only perform dynamic scheduling data. scheduling to reduce the complexity of UE scheduling. For example, if the UE has completed the transmission of SPS data in the corresponding transmission unit, or if there is no SPS data to be transmitted within the transmission time window, it is no longer necessary to combine the two scheduling to perform the transmission unit data transmission in the transmission time window. The transmission direction and/or the confirmation of specific transmission data and other operations are performed to simplify UE operations and save UE power consumption.

The information carried by the first physical control channel and the second physical control channel are both referred to as control information in this embodiment.

In some implementations, the step S202 may include:

In the transmission time window, the first N transmission units or transmission subunits of the first N transmission units whose transmission directions are consistent with the transmission direction of the semi-persistent scheduling data to be transmitted are selected to transmit the semi-persistent scheduling data, wherein the N is a positive integer smaller than M; the M is the number of transmission units included in the transmission time window.

In this embodiment, N transmission units may be selected at one time to transmit the semi-persistent scheduling data, which satisfies the transmission of the semi-persistent scheduling data once.

In some embodiments, one may be selected in step S202, or multiple transmission units may be selected at one time to transmit the semi-persistent scheduling data.

For example, when the resource granularity of the transmission time window is smaller than the minimum resource unit used by the semi-persistent scheduling data transmission for one time, select multiple transmission units or a number of transmission units equal to the minimum resource unit of the semi-persistent scheduling data. The transmission subunit performs the transmission of the semi-persistent scheduling data. Of course, the selection here must be the transmission unit or transmission sub-unit that is consistent with the transmission direction of the semi-persistent scheduling.

In some embodiments, the step S201 may include:

When the configuration of the transmission direction between the control information and the scheduling information of the semi-persistent scheduling conflicts, the transmission direction of the transmission unit or the sub-transmission unit is determined according to the control information. In this embodiment, the configuration of the control information on the transmission direction of each transmission unit or transmission sub-unit within the transmission time window is prioritized.

In other embodiments, the step S201 may further include:

When the configuration of the transmission direction between the control information and the scheduling information of the semi-persistent scheduling does not conflict, the transmission direction of the transmission unit or the sub-transmission unit is determined according to the control information or the scheduling information.

In a word, the configuration of the transmission direction of each transmission unit or transmission sub-unit in the transmission time window can be a combination of the above two methods. In a word, if there is control information, the transmission direction is preferentially determined according to the control information. When there is no control information, the transmission direction is determined according to the scheduling information.

The step S202 may specifically include that when the configuration of the transmission direction between the control information and the scheduling information of the semi-persistent scheduling does not conflict and there is no data to be transmitted corresponding to the control information, in the transmission unit or transmission sub-unit. Transmit semi-persistent scheduling data up. When the configuration of the transmission direction of the transmission unit or the transmission sub-unit does not conflict with the control information and the scheduling information, that is, the configuration of the transmission direction is consistent, and there is no corresponding data to be transmitted in the control information, for example, no dynamic data to be transmitted, the transmission unit or transmission can be transmitted. Subunits are used for the transmission of semi-persistent scheduling data.

In some embodiments, the method further includes the following optional situations:

Option 1:

When the configuration of the transmission direction between the control information and the scheduling information of the semi-persistent scheduling collides, the transmission of the semi-persistent scheduling data on the transmission unit or the transmission sub-unit is abandoned.

Option two:

When the configuration of the transmission direction between the control information and the scheduling information does not conflict and there is data to be transmitted corresponding to the control information, the transmission of the semi-persistent scheduling on the transmission unit or the transmission and sub-unit is abandoned. data.

In optional case 1, since the configuration of the transmission direction of the transmission unit or transmission subunit is inconsistent between the control information and the scheduling information of semi-persistent scheduling, it is obvious that semi-persistent scheduling data cannot be performed on the transmission unit or transmission subunit. Therefore, the transmission of semi-persistent scheduling data on the corresponding transmission unit or transmission sub-unit is abandoned.

In optional case 2, when the configuration of the transmission direction of the transmission unit or the transmission sub-unit does not conflict with the configuration of the control information and the scheduling information, that is, they are consistent, but the control information has corresponding data to be transmitted, for example, there is corresponding dynamic data to be transmitted , the semi-persistent scheduling data requires certain dynamic data transmission, so the transmission of the semi-persistent scheduling data needs to be abandoned on the corresponding transmission unit and/or transmission sub-unit.

The transmission subunit here is a more subdivided transmission resource granularity of the transmission unit. For example, if one transmission subframe is one transmission unit, then one transmission symbol included in one transmission subframe may be one transmission subunit. In short, a transmission unit includes a plurality of transmission sub-units.

The step S100 may include:

Acquiring attribute parameters of the transmission time window; the attribute parameters include: at least one of the window period of the transmission time window, the window length, the resource granularity of the transmission unit, and the time domain position parameters in the time domain position; all The window length is the number of transmission units included in the transmission time window; the resource granularity is the time domain resource length of the transmission unit; the time domain location parameter is used to indicate that the transmission time window is in the time domain s position.

The attribute parameters here can be various related information describing the transmission time window.

The attribute parameters here may include window period, window length, resource granularity and domain location parameters, and the like. The base station can configure and deliver it to the UE together. Before configuring, it can also determine some attribute parameters through negotiation, or determine some attribute parameters by default based on communication protocols, etc. When delivering the attribute parameters to the base station this time, it can be Only the newly added configuration part is delivered.

In short, the attribute parameters may include the acquisition of the above-mentioned various attribute parameters, and the transmission time window may be uniquely determined.

The number of transmission units included in one semi-persistent scheduling period is the semi-persistent scheduling length; the ratio of the window length to the semi-persistent scheduling length is within a preset range;

One of the transmission units is the smallest time-domain transmission unit of the semi-persistent scheduling; for example, if the smallest time-domain transmission unit used by the semi-persistent scheduling is a subframe, the transmission unit included in the transmission time window is a subframe. If the smallest time-domain transmission unit used in semi-persistent scheduling is a transmission symbol, the transmission unit within the transmission time window is a transmission symbol.

The time domain location parameters may include a start time domain location and/or an end time domain location. The start time domain position is the time position of the first transmission unit in the transmission time window in the time domain, and the end time domain position may be the time domain occupied by the last transmission unit in the transmission time window. time location.

The step S110 may include:

Obtain high-level signaling carrying indication information, wherein the indication information is used to indicate the attribute parameter of the transmission time window; the high-level signaling includes: medium access control MAC layer signaling and/or radio resource control RRC layer signaling.

Here, for the base station, the step S100 may be to read the high-layer signaling locally; for the UE, it may be to receive the high-layer signaling.

In specific implementation, the base station may also send downlink semi-persistent scheduling data to the UE, and the UE is not limited to transmitting uplink semi-persistent scheduling data. The semi-persistent transmission time window in FIG. 4 is the aforementioned transmission time window.

In this embodiment, if the control information scheduling and semi-persistent scheduling such as dynamic scheduling corresponding to the control information of the physical control channel are inconsistent with the transmission direction configuration of the same transmission unit within the transmission time window, the scheduling priority of dynamic scheduling is higher. Based on the scheduling priority of the semi-persistent scheduling, the transmission direction of the transmission unit is configured as the transmission direction corresponding to the dynamic scheduling.

For example, in one embodiment, the UE receives the group common PDCCH signaling, indicating that the transmission direction of the nth transmission unit in the transmission time window is the uplink direction; while the semi-persistent scheduling instructs the nth transmission unit to perform downlink reception, obviously The two corresponding scheduling methods are inconsistent in the configuration of the transmission direction of the nth transmission unit, that is, a conflict occurs. At this time, based on the scheduling priority, the transmission direction of the nth transmission unit will be configured as the uplink direction. In this embodiment, first, based on the scheduling priority, the transmission direction of the corresponding transmission unit is determined.

After the transmission direction is determined, the dynamic scheduling data or the semi-persistent scheduling data is transmitted based on the scheduling priority in the corresponding transmission direction.

In this embodiment, the scheduling priority includes: a priority order that can be used to determine a transmission direction, and can also be used to determine a priority order of data transmission. In this embodiment, the priority of dynamic scheduling is higher than that of semi-persistent scheduling, and the transmission direction priority is the same as that of dynamic scheduling. When there is no dynamic scheduling data transmission, the semi-persistent scheduling data is transmitted.

Specifically, the step S110 determines the transmission direction, including at least one or more of the following:

The first:

When the configuration of the transmission direction by the control information scheduling and the semi-persistent scheduling conflict, the transmission direction of the corresponding transmission unit is configured according to the dynamic scheduling. In this manner, once there is a conflict between the control information scheduling and the semi-persistent scheduling, the transmission direction of the corresponding transmission unit is directly configured based on the control information scheduling.

The second:

When the configuration of the transmission direction by the control information scheduling and the semi-persistent scheduling is consistent, the transmission direction of the corresponding transmission unit is configured according to the control information scheduling or the semi-persistent scheduling. In this method, the transmission directions of the control information scheduling and the semi-persistent scheduling are the same, so the transmission direction of the corresponding transmission unit can be determined according to any one of the control information scheduling and the semi-persistent scheduling.

In short, when the two scheduling methods of control information scheduling and semi-persistent scheduling conflict with the transmission direction configuration of the same transmission unit, the control information scheduling shall prevail; if there is no conflict, the semi-persistent scheduling shall prevail.

In some embodiments, the UE may receive the control information scheduled by the control information and the semi-persistent scheduling information scheduled by the semi-persistent scheduling. The control information and semi-persistent scheduling information scheduled by the control information explicitly or implicitly indicate the transmission direction of the transmission unit within the transmission time window. Explicit indications carry explicit indication information. Implicit indications can be based on the corresponding relationship pre-negotiated by the base station and the UE or based on communication protocols, etc., using the scheduling information (resource identifier of transmission resources) of control information and/or semi-persistent scheduling information. The corresponding relationship between the parameters and the transmission direction implicitly indicates the transmission direction of the corresponding transmission unit to the UE.

If there is a conflict between control information scheduling and semi-persistent scheduling, the transmission direction indicated by the control information scheduling is used to configure the transmission direction of a transmission unit. The transmission unit transmits data scheduled by the control information in this direction, otherwise the UE may not transmit data on this transmission unit.

If the control information scheduling and the semi-persistent scheduling do not conflict, the transmission direction configured by the current transmission unit can be used for the transmission of the data scheduled by the control information or the transmission of the semi-persistent scheduling data, and the transmission conflict needs to be resolved at this time. In this embodiment, firstly, the scheduling priority is used to resolve the transmission direction conflict at the second level, and secondly, the transmission priority included in the scheduling priority is used to resolve the transmission conflict.

Optionally, the step S120 may include one or more of the following situations:

The first:

When the scheduling information of the control information and the scheduling information of the semi-persistent scheduling collide with the configuration of the transmission direction, the data scheduled by the control information is transmitted or the data is not transmitted in the transmission unit in which the transmission direction has been configured. The configuration conflict here is: the two scheduling pairs have different configurations of the transmission direction of the same transmission unit in the transmission time window.

The second:

When the configuration of the transmission direction of the control information and the scheduling information of the semi-persistent scheduling is consistent, and there is no data scheduled by the control information to be transmitted, the semi-persistent scheduling data is transmitted in the transmission unit. The configurations here are consistent: the two scheduling pairs have the same configuration of the transmission direction of the same transmission unit in the transmission time window.

The third:

When the scheduling information of the control information scheduling and the semi-persistent scheduling have the same configuration of the transmission direction, and there is data scheduled by the control information to be transmitted, the data scheduled by the control information is transmitted in the transmission unit.

Further, the method also includes:

Monitor the control information scheduled by the control information at the start time of the transmission time window or after entering the discontinuous reception active state.

In this embodiment, in order to detect a collision, from the start time of the transmission time window or before the start time, the monitoring of the physical control channel starts after entering the discontinuous connection (DTX) active state.

The physical control channel control here may be: the aforementioned group common PDCCH and/or UE specific PDCCH, etc. Further, the scheduling priority corresponding to the control information of the common physical control channel is higher than the scheduling priority corresponding to the control information of the user equipment dedicated physical control channel. In this way, if there is conflict between the control information of the group common PDCCH and the UE specific PDCCH, the scheduling configuration of the control information of the group common PDCCH is preferentially satisfied. The scheduling priority here also includes the configuration priority of the transmission direction and the transmission priority of the scheduled data.

Optionally, the window period of the transmission time window is equal to the semi-persistent scheduling period of the semi-persistent scheduling; the start time of the transmission time window is not later than the corresponding start time of the semi-persistent scheduling.

For example, if the semi-persistent scheduling period is equal to M time slots, the window period is also equal to M time slots. However, it should be noted that the number of transmission units included in the transmission time window is not less than the number of transmission units included in the window period.

In this embodiment, the start time of the transmission time window is not later than the start time of the corresponding semi-persistent scheduling, so that the monitoring of the control information can be entered as soon as possible, and the semi-persistent scheduling can be transmitted as soon as possible. The data transmission unit completes the transmission of semi-persistent scheduling data.

Optionally, the number of transmission units included in the transmission time window is the window length; the number of transmission units included in the semi-persistent scheduling period is the semi-persistent scheduling length; the window length and the semi-persistent scheduling length are divided. ratio, within a preset range. The preset range here can be 1/2 to 1/3, etc.

Optionally, high layer signaling carrying the indication information of the transmission time window is received, wherein the high layer signaling includes: MAC layer signaling and/or RRC layer signaling.

Further, the indication information includes at least one of the following:

an indication parameter indicating the start time domain position and the end time domain position of the transmission time window;

Indication parameters indicating the start time domain position and window length of the transmission time window;

Indication parameters indicating the end time domain position and window length of the transmission time window.

In some embodiments, the indication information can also be used to indicate the relative position parameter of the scheduling period of the semi-persistent scheduling and the time domain of the transmission time window.

For example, in some embodiments a semi-persistent scheduling period has been indicated, indicating a relative location parameter, eg, the first x transmission units of the semi-persistent scheduling period are selected as the transmission time window. For another example, indicate the offset of the start time and position of the transmission time window and the start time domain position of the semi-persistent scheduling period, and indicate the end time and position of the transmission time window and the start and end of the semi-persistent scheduling period. The offset of the time domain position. Through the indication of the offset and the length of the window, the position of the transmission time window in the time domain can be easily determined.

FIG. 4 is a schematic diagram showing a corresponding relationship between a transmission time window and a semi-persistent scheduling period.

T1 is the scheduling period of semi-persistent scheduling; T2 is the window period of the transmission time window. Obviously, the window period is earlier than the scheduling period of the corresponding semi-persistent scheduling, and the number of transmission units included in the transmission time window is smaller than the number of transmission units included in the entire window period. In Figure 4, the window period is shifted forward by two transmission units from the scheduling period.

The step S110 may include:

If there is still semi-persistent scheduling data to be transmitted in the transmission time window, the transmission direction of the transmission unit in the transmission time window is determined according to the scheduling priority.

In this embodiment, in order to reduce the unnecessary operations of the UE as little as possible and reduce the power consumption of the UE, only when there is semi-persistent scheduling data to be transmitted, the scheduling priority is determined based on the scheduling of the control information and the semi-persistent scheduling. The transmission direction, otherwise, the determination of the transmission direction and subsequent data transmission can be performed only based on the scheduling of the control information.

For example, if there is no SPS data that needs to be transmitted within a transmission time window, it is not necessary to combine the two scheduling methods to determine the transmission direction that can transmit the corresponding SPS data, and perform the operation of the corresponding SPS data. If the corresponding semi-persistent scheduling data in one transmission time frame has been transmitted, steps S110 to S120 may not be performed, so as to simplify the UE operation. For another example, if there is always untransmitted semi-persistent scheduling data within a transmission time pass, steps S110 to S120 need to be performed in combination with two scheduling methods for each transmission unit of the transmission unit.

Several specific examples are provided below in conjunction with any one of the above embodiments:

Example 1:

This example presents a semi-persistent scheduling transmission enhancement method. In the method, the base station uses high-level signaling to configure the transmission time window of semi-persistent scheduling transmission. After the physical layer downlink control information is activated, the user equipment can use the available transmission time window on the basis of ensuring that the dynamic scheduling is greater than the priority of the semi-persistent scheduling. On the transmission unit, the semi-persistent scheduling data is sent or received. This solution can shorten the transmission delay of semi-persistent scheduling data and increase the flexibility of semi-persistent scheduling.

Specifically, in this example, according to the transmission time window configured by the base station through the high-level signaling, the user equipment can be used on the transmission unit of the available transmission time window on the basis of ensuring that dynamic scheduling is superior to the scheduling priority of semi-persistent scheduling. , to send or receive semi-persistent scheduling data to increase scheduling flexibility. The specific implementation method is summarized as follows:

The base station configures the transmission time window for the user equipment by means of high-level signaling configuration. Specifically, the configuration information and method include:

The base station configures the transmission time window for the user equipment by means of high-level signaling configuration, which specifically includes the transmission period, timing granularity and time domain position of the transmission time window;

The base station configures the transmission time window for the user equipment by means of high-level signaling configuration, and the transmission time window information will be activated or released together with the physical layer activation or release signaling accompanying the semi-persistent scheduling transmission.

The UE performs the judgment and decision of the semi-persistent scheduling data transmission according to the transmission time window information configured by the read high-level signaling, and the specific methods include:

Enter the DRX active state at or before the beginning of the transmission time window to monitor dynamic scheduling information, specifically including monitoring the control information carried by group common PDCCH and UE specific PDCCH;

According to the acquired control information of dynamic scheduling, combined with the configuration information of semi-persistent data transmission, the UE takes dynamic scheduling better than semi-persistent scheduling (specifically, group common PDCCH is prior to UE specific PDCCH prior to SPS) as the criterion. Within the window, it is judged in turn whether to schedule semi-persistently transmitted data.

Example 2:

This example provides a data transmission method for enhanced semi-persistent scheduling, which is described below from the base station side and the UE side respectively.

base station side

In the design of the high-level configuration message, the base station configures the transmission time window for the user by means of high-level signaling configuration. Specifically, the configuration information and the corresponding configuration method include:

Window period of the transmission time window:

The design of the transmission time window is to ensure the timeliness and accuracy of the transmission of semi-persistent scheduling data packets in each transmission interval, so the transmission time window should be configured to appear periodically, and its periodic and semi-persistent scheduling The transmission cycle remains the same.

Example 1: One of the above-mentioned periodic transmission time windows As shown in FIG. 4 , the window period T1 of the transmission time window is equal to the scheduling period T2 of the semi-persistent scheduling.

The time domain position of the transmission time window:

After the window period of the transmission time window is determined, it is necessary to further determine its time domain position in each transmission period, and the indicating method can be specifically represented by the following three options:

Option 1: the start time domain position and the end time domain position of the transmission time window;

Option 2: the start time domain position and window length of the transmission time window;

Option 3: End time domain position and window length of the transmission time window.

Option 4: The start position and end position of the transmission time window may be indicated by a relative position parameter to the transmission unit of the semi-persistent scheduling data. For example, in Figure 4, the transmission unit whose starting time domain position of the transmission time window is the semi-persistent scheduling data is shifted forward by 2 transmission units, and the transmission unit whose end position is the semi-persistent scheduling data is shifted backward by 2 transmission units .

The window length of the transmission time window can be represented by its ratio to the period of semi-persistent scheduling transmission. For example, in FIG. 4 , the transmission period of semi-persistent scheduling is T1 = T2 = 10 transmission unit times, and the window length of the transmission time window = 5 transmission unit times. Therefore, the window length of the transmission time window = 1/2 Semi-persistent scheduling transmission period.

Granularity of the transmission time window:

The time domain position of the above-mentioned transmission time window and the determination of the window period need to be characterized by a certain time unit. This time unit is the granularity of the transmission time window, which should be consistent with the granularity of semi-persistent scheduling. The transmission unit is granular, and the transmission unit includes but is not limited to subframes, time slots, mini-slots, and the like.

(2) Physical layer control information

The transmission time window configured by the base station for the user equipment by means of high-level signaling configuration will be activated or released through physical layer control information, and the physical layer control information will multiplex the activation or release information of semi-persistent scheduling transmission.

UE side

According to the transmission time window information configured by the UE read high-level signaling, once it is in the active state, the UE will enter the DRX active state at the beginning of the transmission time window or before the start, and monitor the dynamic scheduling information after entering the DRX active state, which includes: Control information carried by group common PDCCH and UE specific PDCCH. According to the dynamic scheduling information of the dynamic scheduling and the semi-persistent scheduling information of its own semi-persistent scheduling, the UE performs the judgment and decision of the semi-persistent scheduling data transmission unit by transmission unit within the transmission time window. The specific methods include:

If the user color is not within this transmission period, there is data waiting for semi-persistent scheduling transmission

A. When the semi-persistent scheduling transmission configuration is different from the transmission direction of the transmission unit configured by the group common PDCCH, the direction of the transmission unit is consistent with the configuration of the group common PDCCH,

B. When the transmission direction of the transmission unit in the semi-persistent scheduling transmission configuration is the same as that in the group common PDCCH configuration, and there is dynamically scheduled dynamic scheduling data, the transmission unit is used to send or receive the dynamic scheduling data.

C. When the transmission direction of the transmission unit in the semi-persistent scheduling transmission configuration is the same as that in the group common PDCCH configuration, and when there is no dynamic scheduling data for dynamic scheduling, the transmission unit is used to send or receive data for semi-persistent scheduling.

D. When the group common PDCCH does not limit the transmission direction of the transmission unit, the transmission unit sends or receives dynamic data or semi-persistent scheduling data according to the principle that dynamic scheduling data is prior to semi-persistent scheduling.

If the user equipment does not have data waiting for semi-persistent scheduling transmission in this transmission period. Then, the transmission format of the transmission unit and the transmitted data are jointly determined by the group common PDCCH and the UE specific PDCCH.

In particular, the data transmission performed by the transmission unit here is divided into two directions: uplink and downlink, wherein the uplink of the semi-persistent scheduling transmission means transmitting the uplink data sent by the UE to the base station; the downlink of the semi-persistent scheduling transmission means monitoring and receiving the base station. Downlink data sent to the UE.

In this example, the base station determines an optimal transmission unit for transmitting SPS within the transmission time window based on semi-persistent scheduling. However, other transmission units within the transmission time window described in this example may also use other transmission units to replace the transmission SPS under the condition of no dynamic scheduling conflict.

Fig. 7 shows the uplink SPS transmission unit for semi-persistent scheduling, but in fact, in combination with dynamic scheduling and semi-persistent scheduling, the uplink SPS transmitted by another transmission unit within the transmission time window is selected.

Figure 8 shows the downlink SPS transmission unit for semi-persistent scheduling, but in fact, combined with dynamic scheduling and semi-persistent scheduling, the downlink SPS transmitted by another transmission unit within the transmission time window is selected.
