Detailed Description

If scheduling conflict between dynamic scheduling and semi-persistent scheduling for the same scheduling time domain unit occurs, the UE may work in a confused state, or after the semi-persistent scheduling is conflicted, data of the semi-persistent scheduling cannot be transmitted, or the semi-persistent scheduling needs to be reset. The scheduling time domain unit may be a frame, a subframe, a time slot, or the like. In view of the above, as shown in fig. 1, the present embodiment provides a method for semi-persistently scheduled data transmission, which is applied in 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, and if the communication device is a UE, the transmission of the semi-persistent scheduling data is the transmission of the semi-persistent scheduling data in the downlink direction. The transmission of the semi-persistent scheduling data comprises:

step S100: obtaining a configured semi-persistently scheduled transmission time window, wherein the transmission time window comprises: a plurality of transmission units;

step S200: and according to the acquired control information of the physical control channel, one or more transmission units selected in the transmission time window carry out the transmission of the semi-persistent scheduling data.

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

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

When the main execution entity currently executing steps S100 to S200 is UE, in step S100, the UE receives the attribute parameter of the transmission time window sent by the base station, for example, receives the broadcasted system message or information such as radio resource control information, so as to obtain the configured semi-persistent scheduled transmission time window. 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.

Listening, for the UE, to the first physical control channel and/or the second physical control channel may include: before or when the time domain starting position corresponding to the transmission time window, entering a semi-continuous receiving (DRX) activated state; after entering the DRX active state, monitoring 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 transmission priority of data such as dynamically scheduled control information is higher than 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. For example,

The first physical control channel may be a control channel for a group of UEs, and may typically be used for transmitting control information for transport formats with higher transmission priority for dynamic scheduling and/or the like than for semi-persistent scheduling data. The second physical control channel may be signaling, which is transmitted to a specific UE in a unicast manner for a single user, indicating a control channel for transmitting specific data.

Specifically, for example, the first Physical Control Channel may be a group common Physical Downlink Control Channel (group common PDCCH); the second Physical Control Channel may be a UE specific Physical Downlink Control Channel (UE specific PDCCH), and may be used for dynamic scheduling.

The control information of the group common PDCCH may carry information related to a transmission format of a scheduling unit provided by a group of user equipments, where the scheduling unit may be a frame, a subframe, a slot, or the like.

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

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

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

For example, if s1 transmission units are consumed by using the semi-persistent scheduling once, in this embodiment, the number of transmission units included in the transmission time window is greater than the s 1.

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

In the embodiment, a transmission time window is introduced, the transmission time window comprises at least two transmission units, data to be transmitted by semi-persistent scheduling (i.e. semi-persistent scheduling data) can be selected from any one or more transmission units in the transmission time window for transmission, rather than being limited to the semi-persistent scheduling unit indicating only one transmission unit for transmission, once the transmission unit is collided or delayed, the semi-persistent scheduling data has to be delayed for transmission or not transmitted, so that the flexibility and the transmission success rate of the semi-persistent scheduling transmission are improved, and the problem of repeated scheduling is reduced. The transmission of the semi-persistent scheduling data herein may be uplink transmission and/or downlink transmission.

Transmission collisions between high transmission priority data (high transmission priority data herein refers exclusively to data having a transmission priority higher than that of semi-persistently scheduled data, e.g., dynamically scheduled data) such as dynamic scheduling and semi-persistently scheduled data can be embodied in two levels:

in the first layer, there is scheduling collision between high transmission priority data and semi-persistent scheduling, and there is inconsistency of scheduled transmission directions, for example, the mth transmission unit is scheduled for uplink transmission by dynamic scheduling, and the mth transmission unit is required for downlink transmission by semi-persistent scheduling. Thus, not only does both schedules need to occupy the transmission unit, but also the transmission directions of the transmission units are configured to be different. For example, in some transmission scenarios, the transmission format of a scheduled time-domain unit may be multiple. For example, in a 5G scenario. The transmission format includes: the uplink transmission formats of all uplink transmissions and the downlink transmission formats of all downlink transmissions comprise uplink and downlink mixed transmission formats.

If a scheduling time domain unit is a frame, the frame can be an uplink transmission frame, a downlink transmission frame, and a hybrid transmission frame. The transmission format corresponding to the uplink transmission frame is as follows: the transmission direction of each transmission unit in the uplink transmission frame is the uplink direction. The corresponding transmission format of the downlink transmission frame is as follows: 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 as follows: some transmission units are in the uplink direction, and the other transmission units are in the downlink direction. The downlink direction is as follows: direction from the base station to the UE. The uplink direction is: UE to base station direction.

In the second level, both high transmission priority data and semi-persistent scheduling schedule the same transmission unit, resulting in scheduling collisions. For example, high transmission priority data requires the transmission of dynamically scheduled data using the mth transmission unit, and semi-persistent scheduling requires the transmission of semi-persistent scheduled data using the mth transmission unit.

The high transmission priority data and the semi-persistent scheduling data may be service data scheduled and transmitted by using a corresponding scheduling method, and may include: upstream data and/or downstream data.

The length of the time domain resource specifically corresponding to the transmission unit may be determined according to the scheduling time domain unit. For example, if a time slot is scheduled, and the time slot may also include the three transmission formats, the transmission unit may be a micro-slot or a transmission symbol. In this way, it may happen that the transmission format of each transmission slot is not fixed, and the transmission direction of each transmission unit in each transmission slot is not fixed. In this way, the method provided by this embodiment separately solves the conflicts of the two layers based on the scheduling priority.

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

step S201: determining the transmission direction of at least one transmission unit and/or at least one transmission subunit in at least one transmission unit in the transmission time window according to the acquired control information of the physical control channel; wherein the transmission direction comprises: an uplink direction and a downlink direction;

step S202: and selecting a transmission unit or a transmission subunit with the transmission direction consistent with the transmission direction of the semi-persistent scheduling data to be transmitted in the transmission time window, and transmitting 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 in the transmission time is determined first, and then the transmission unit or the transmission sub-unit consistent with the transmission direction of the semi-persistent scheduling data is selected for the semi-persistent scheduling data transmission.

Only when the transmission unit still has the semi-persistent scheduling data to be transmitted, the transmission unit of the transmission time window is used for transmitting the dynamic scheduling data or the semi-persistent scheduling data by combining the control channel signaling; otherwise, the UE may only perform dynamic scheduling to reduce the complexity of UE scheduling. For example, if the UE has already completed the semi-persistent scheduling data transmission in the corresponding transmission unit, or if there is no semi-persistent scheduling data to be transmitted in the transmission time window, the UE may not combine the two schedules to perform operations such as the transmission direction of the transmission unit in the transmission time window and/or the confirmation of specific transmission data, so as to simplify the UE operation and save the UE power consumption.

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

In some implementations, the step S202 may include:

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

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

For example, when the resource granularity of the transmission time window is smaller than the minimum resource unit used for transmitting the semi-persistent scheduling data at one time, a plurality of transmission units or transmission sub-units of the plurality of transmission units which are equal to the minimum resource unit of the semi-persistent scheduling data are selected for transmitting the semi-persistent scheduling data. Of course, transmission units or transmission sub-units are selected here which must be in accordance with the transmission direction of the semi-persistent scheduling.

In some embodiments, the step S201 may include:

and when the control information conflicts with the configuration of the scheduling information of the semi-persistent scheduling on the transmission direction, determining the transmission direction of the transmission unit or the sub-transmission unit according to the control information. In this embodiment, the configuration of the control information to the transmission direction of each transmission unit or transmission sub-unit in the transmission time window is prioritized.

In other embodiments, the step S201 may further include:

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

The step S202 may specifically include transmitting the semi-persistent scheduling data on the transmission unit or the transmission subunit when the control information and the scheduling information of the semi-persistent scheduling do not conflict with each other in configuration of the transmission direction and there is no to-be-transmitted data corresponding to the control information. When the configuration of the transmission direction of the transmission unit or the transmission subunit is not conflicted or consistent by the control information and the scheduling information, and the control information has no corresponding data to transmit, for example, no dynamic data to transmit, the transmission unit or the transmission subunit may be used for the transmission of the semi-persistent scheduling data.

In some embodiments, the method further comprises the following optional cases:

optional cases one:

and when the control information and the scheduling information of the semi-persistent scheduling conflict with the configuration of the transmission direction, giving up the transmission of the semi-persistent scheduling data on the transmission unit or the transmission sub-unit.

Optional case two:

In an optional case, since the configuration of the control information and the scheduling information of the semi-persistent scheduling for the transmission direction of the transmission unit or the transmission sub-unit are not consistent, it is obvious that the transmission of the semi-persistent scheduling data on the transmission unit or the transmission sub-unit cannot be performed, and therefore, the transmission of the semi-persistent scheduling data on the corresponding transmission unit or the transmission sub-unit is abandoned.

In the second option, when the control information and the scheduling information do not conflict or coincide with each other with respect to the configuration of the transmission direction of the transmission unit or the transmission sub-unit, but the control information has corresponding data to be transmitted, for example, if there is corresponding dynamic data to be transmitted, the semi-persistent scheduling data needs to be necessarily transmitted by the dynamic data, so that the transmission of the semi-persistent scheduling data needs to be abandoned on the corresponding transmission unit and/or transmission sub-unit.

The transmission sub-unit is a more subdivided transmission resource granularity of the transmission unit, for example, one transmission subframe is one transmission unit, and one transmission symbol included in one transmission subframe may be one transmission sub-unit. In summary, a transmission unit comprises a plurality of transmission subunits.

The step S100 may include:

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

The attribute parameters may include window period, window length, resource granularity, and time domain location parameters. The base station can be configured together and issued to the UE, before configuration, part of attribute parameters can be determined first through negotiation, or part of attribute parameters can be determined first through defaults based on a communication protocol and the like, and when the attribute parameters are issued to the base station at this time, only the newly added configuration part can be issued.

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

one of the transmission units is a minimum time domain transmission unit of the semi-persistent scheduling; for example, if the minimum 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. And if the minimum time domain transmission unit used by the semi-persistent scheduling is a transmission symbol, the transmission unit in the transmission time window is the transmission symbol.

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

The step S110 may include:

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

One of the transmission units is: one subframe, one slot, one minislot, or one transmission symbol.

and the transmission unit is used for transmitting the semi-persistent scheduling data by one or more transmission units selected in the transmission time window according to the acquired control information of the physical control channel.

And the transmission module corresponds to the receiving and transmitting antenna and is used for transmitting the semi-persistent scheduling data.

Optionally, the direction determining module may be configured to perform at least one of:

Optionally, the transmission module may be configured to transmit the semi-persistent scheduling data on the transmission unit or the transmission subunit when the control information and the scheduling information of the semi-persistent scheduling do not conflict with each other in configuration of the transmission direction and there is no to-be-transmitted data corresponding to the control information.

In still other embodiments, the transmission module may be further configured to perform at least one of: : when the control information and the scheduling information of the semi-persistent scheduling conflict with the configuration of the transmission direction, giving up the transmission of the semi-persistent scheduling data on the transmission unit or the transmission sub-unit;

In some embodiments, the obtaining unit 100 is specifically configured to obtain an attribute parameter of the transmission time window; the attribute parameters include: at least one of a window period of the transmission time window, a window length, a resource granularity of a transmission unit, and a time domain position parameter at a time domain position; 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 position parameter is used for indicating the position of the transmission time window in the time domain.

The technical solution of the present invention is further described in detail with reference to dynamic scheduling data and embodiments.

As shown in fig. 3, the present embodiment provides a method for semi-persistently scheduled data transmission, including:

step S110: determining the transmission direction of a transmission unit in a transmission time window according to scheduling priorities respectively corresponding to scheduling and semi-persistent scheduling of control information, wherein the transmission direction comprises: an uplink direction and a downlink direction; the control information is information such as a control instruction transmitted by a physical control channel.

Step S120: and transmitting the dynamic scheduling data or the semi-persistent scheduling data in a configured transmission direction by using the transmission unit according to the scheduling priority.

In fig. 3, semi-persistent scheduling data transmission of the UE is taken as an example, and in a specific implementation, the base station may also send downlink semi-persistent scheduling data to the UE, and is not limited to the UE transmitting uplink semi-persistent scheduling data. The semi-persistent tti in fig. 4 is the tti described above.

In this embodiment, if the control information scheduling such as dynamic scheduling and semi-persistent scheduling corresponding to the control information of the physical control channel is inconsistent with the transmission direction configuration of the same transmission unit in the transmission time window, the scheduling priority of the dynamic scheduling is higher than the scheduling priority of the semi-persistent scheduling, and 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 a group common PDCCH signaling indicating that the transmission direction of the nth transmission unit in the transmission time window is the uplink direction; and the semi-persistent scheduling indicates the nth transmission unit to perform downlink reception, and obviously, the two corresponding scheduling modes are inconsistent in the transmission direction configuration of the nth transmission unit, that is, a collision occurs. At this time, the transmission direction of the nth transmission unit is configured to be the uplink direction based on the scheduling priority. In this embodiment, first, the transmission direction of the corresponding transmission unit is determined based on the scheduling priority.

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

In this embodiment, the scheduling priorities include: can be used for determining the priority of the transmission direction and can also be used for determining the priority of data transmission. In this embodiment, the dynamic scheduling priority is higher than the semi-persistent scheduling priority, the transmission direction priority is the same as the dynamic scheduling configuration, if the transmission direction configurations of two types of scheduling for one transmission unit are the same, the dynamic scheduling data is preferentially transmitted, and when no dynamic scheduling data is transmitted, the semi-persistent scheduling data is transmitted again.

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

the first method comprises the following steps:

and when the control information scheduling and the semi-persistent scheduling conflict with the configuration of the transmission direction, configuring the transmission direction of the corresponding transmission unit according to the dynamic scheduling. In this way, once the control information scheduling and the semi-persistent scheduling conflict, the transmission direction of the corresponding transmission unit is configured directly based on the control information scheduling.

And the second method comprises the following steps:

and when the control information scheduling and the semi-persistent scheduling are consistent in configuration of the transmission direction, configuring the transmission direction of the corresponding transmission unit according to the control information scheduling or the semi-persistent scheduling. In this embodiment, since the transmission directions corresponding to the control information scheduling and the semi-persistent scheduling are the same, the transmission direction of the corresponding transmission unit can be determined according to either the control information scheduling or the semi-persistent scheduling

In a word, when two scheduling modes, namely control information scheduling and semi-persistent scheduling, conflict is configured for the transmission direction of the same transmission unit, the control information scheduling is taken as the standard; if no conflict occurs, semi-persistent scheduling may be the standard.

In some embodiments, the UE may receive the control information scheduled by the control information and semi-persistent scheduling information scheduled by the semi-persistent scheduling. Control information of control information scheduling and semi-persistent scheduling information explicitly or implicitly indicate the transmission direction of transmission units within the transmission time window. The explicit indication carries explicit indication information, and the implicit indication may implicitly indicate the transmission direction of the corresponding transmission unit to the UE based on a correspondence between parameters such as scheduling information (resource identifier of transmission resource) of control information and/or semi-persistent scheduling information and the transmission direction based on a correspondence negotiated by the base station and the UE in advance or based on a communication protocol.

If conflict between control information scheduling and semi-persistent scheduling occurs, a transmission direction indicated by the control information scheduling is adopted to configure the transmission direction of a transmission unit, if data needing to be transmitted in the transmission direction in the control information scheduling currently exists, the transmission unit is used for transmitting the data scheduled by the control information in the direction, otherwise, the UE can not transmit the data in the transmission unit.

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

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

the first method comprises the following steps:

and when the control information scheduling and the scheduling information of the semi-persistent scheduling conflict with the configuration of the transmission direction, transmitting the data scheduled by the control information or not transmitting the data in the transmission unit with the configured transmission direction. The configuration conflict here is: the two kinds of scheduling have different configurations for the transmission direction of the same transmission unit in the transmission time window.

And the second method comprises the following steps:

and when the control information and the scheduling information of the semi-persistent scheduling are consistent in configuration of a transmission direction and no data scheduled by the control information to be transmitted exists, transmitting the semi-persistent scheduling data in the transmission unit. The configuration here is consistent with: the two schedules have the same configuration for the transmission direction of the same transmission unit within the transmission time window.

And the third is that:

and when the configuration of the control information scheduling and the scheduling information of the semi-persistent scheduling to the transmission direction is consistent and the data scheduled by the control information is to be transmitted, transmitting the data scheduled by the control information in the transmission unit.

Further, the method further comprises:

and monitoring the control information scheduled by the control information at the initial time of the transmission time window or after entering a discontinuous reception activated state.

In this embodiment, to detect collision, the physical control channel starts to listen after entering a Discontinuous Transmission (DTX) active state from the beginning or before the beginning of the transmission time window.

The physical control channel control here may be: the group common PDCCH and/or the UE specific PDCCH. 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 dedicated physical control channel of the user equipment. In this way, if the control information of the group common PDCCH and the UE specific PDCCH conflicts, the scheduling configuration of the control information of the group common PDCCH is preferentially satisfied. Here, the scheduling priority also includes configuration priority of the transmission direction and transmission priority of the scheduled data.

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

For example, if the semi-persistent scheduling period is equal to M slots, then the window period is also equal to M slots. It should be noted, however, 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 monitoring of the control information can be ensured as soon as possible, and a transmission unit capable of transmitting the semi-persistent scheduling data is selected as soon as possible to complete transmission of the semi-persistent scheduling data.

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

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

Further, the indication information includes at least one of:

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

an indication parameter indicating a starting time domain position and a window length of the transmission time window;

an indication parameter indicating an end time domain position of the transmission time window and a window length.

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

For example, in some embodiments a semi-persistent scheduling period has been indicated, a relative position parameter is indicated, e.g., the first x transmission units of the semi-persistent scheduling period are selected as the transmission time window. For another example, the offset between the start time and position of the transmission time window and the start time domain position of the semi-persistent scheduling period is indicated, and the offset between the end time and position of the transmission time window and the start end time domain position of the semi-persistent scheduling period is indicated. The position of the transmission time window in the time domain can be easily determined by the indication of the offset in combination with the window length.

Fig. 4 is a diagram illustrating 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 less than the number of transmission units included in the whole window period. In fig. 4, the window period is offset two transmission units forward from the scheduling period.

The step S110 may include:

and if the semi-persistent scheduling data to be transmitted still exist in the transmission time window, determining the transmission direction of the transmission unit in the transmission time window according to the scheduling priority.

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

For example, if there is no semi-persistent scheduling data to be transmitted in one transmission time window, the transmission direction in which the corresponding semi-persistent scheduling data can be transmitted is determined without combining the two scheduling methods, and the corresponding semi-persistent scheduling data is operated. If the transmission of the corresponding semi-persistent scheduling data within one transmission time is completed, step S110 to step S120 may not be performed any more, so as to simplify the UE operation. For another example, if there is semi-persistent scheduling data that has not been transmitted in a transmission time period, step S110 to step S120 need to be performed for each transmission unit of the transmission unit by combining two scheduling manners.

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

example 1:

the present example proposes a semi-persistent scheduling transmission enhancement method. The method uses high-level signaling to configure a transmission time window of semi-persistent scheduling transmission through a base station, and after physical layer downlink control information is activated, user equipment transmits or receives semi-persistent scheduling data on a transmission unit of an available transmission time window on the basis of ensuring that dynamic scheduling is greater than semi-persistent scheduling priority. The scheme can shorten the transmission delay of the semi-persistent scheduling data and increase the flexibility of the semi-persistent scheduling.

Specifically, in this example, the ue can transmit or receive semi-persistent scheduling data on a transmission unit of an available transmission time window on the basis of ensuring that dynamic scheduling is better than scheduling priority of semi-persistent scheduling according to a transmission time window configured by the base station through high-level signaling, thereby increasing scheduling flexibility. The specific implementation method is summarized as follows:

the base station configures a transmission time window for the user equipment in a high-level signaling configuration mode, and specifically, the configuration information and method include:

a base station configures a transmission time window for user equipment in a high-level signaling configuration mode, wherein the transmission time window specifically comprises a transmission period, a timing granularity and a time domain position of the transmission time window;

the base station configures a transmission time window for the user equipment in a high-level signaling configuration mode, and the transmission time window information activates or releases the physical layer activation or release signaling accompanied with the semi-persistent scheduling transmission.

The UE judges and decides the semi-persistent scheduling data transmission according to the read transmission time window information configured by the high-level signaling, and the specific method comprises the following steps:

entering a DRX (discontinuous reception) active state at or before the beginning of a transmission time window to monitor dynamic scheduling information, wherein the dynamic scheduling information specifically comprises control information carried by a group common PDCCH (physical downlink control channel) and a UE specific PDCCH (user equipment);

and the UE sequentially judges whether to schedule the semi-persistent transmission data in the transmission time window according to the acquired control information of the dynamic scheduling and the configuration information of the semi-persistent data transmission by taking the dynamic scheduling to be superior to the semi-persistent scheduling (specifically, the group common PDCCH is superior to the UE specific PDCCH to be superior to the SPS) as a criterion.

Example 2:

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

Side of base station

The design of high-level configuration information, a base station configures a transmission time window for a user in a high-level signaling configuration mode, specifically, the configuration information and the corresponding configuration method comprise:

window period of the transmission time window:

the transmission time window is designed to ensure the timeliness and accuracy of the semi-persistent scheduling data packet transmission in each transmission interval, so the transmission time window should be configured to occur periodically, and the period of the transmission time window is consistent with the transmission period of the semi-persistent scheduling.

Example 1: one such periodic transmission time window is shown in fig. 4, where the window period T1 of the transmission time window is equal to the scheduling period T2 of the semi-persistent scheduling.

Time domain position of the transmission time window:

after the window period of the transmission time window is determined, the time domain position of the transmission time window in each transmission period needs to be further determined, and the indication method thereof can be specifically represented by the following three options:

option 1: a start time domain position and an end time domain position of the transmission time window;

option 2: a starting time domain position and a window length of the transmission time window;

option 3: an end time domain position of the transmission time window and a window length.

Option 4: the start and end positions of the transmission time window may be indicated by their relative position parameters with respect to transmission units of semi-persistently scheduled data. For example, in fig. 4, the start time domain position of the transmission time window is 2 transmission units forward offset for the transmission unit of the semi-persistent scheduling data, and the end position is 2 transmission units backward offset for the transmission unit of the semi-persistent scheduling data.

The window length of the transmission time window may be represented by its ratio to the period of the semi-persistent scheduled transmission. For example, in fig. 4, the transmission period T1-T2-10 transmission unit times of semi-persistent scheduling, and the window length of the transmission time window is 5 transmission unit times, so the window length of the transmission time window is 1/2-half-persistent scheduling transmission period.

Granularity of transmission time window:

the determination of the time domain position of the transmission time window and the window period needs to be characterized by a certain time unit, which is the granularity of the transmission time window, and should be consistent with the granularity of the semi-persistent scheduling, i.e. the granularity of the transmission unit of the semi-persistent scheduling is used as the granularity, and the transmission unit includes but is not limited to a subframe, a time slot, a micro-slot, etc.

(2) Physical layer control information

The base station activates or releases the transmission time window configured for the user equipment by a high-level signaling configuration mode through physical layer control information, and the physical layer control information multiplexes the activation or release information of the semi-persistent scheduling transmission.

UE side

According to the read transmission time window information configured by the high-level signaling, once the transmission time window information is in an active state, the UE enters a DRX active state at or before the beginning of the transmission time window, and monitors dynamic scheduling information after entering the DRX active state, wherein the dynamic scheduling information specifically comprises group common PDCCH and control information carried by UE specific PDCCH. The UE judges and decides semi-persistent scheduling data transmission by transmission units within a transmission time window according to the dynamic scheduling information monitored by the UE and the semi-persistent scheduling information of self semi-persistent scheduling, and the specific method comprises the following steps:

if the user color is not in the transmission period, the data waiting for the semi-persistent scheduling transmission exists

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

B. when the transmission direction of the transmission unit of the semi-persistent scheduling transmission configuration and the group common PDCCH configuration is the same and dynamic scheduling data of dynamic scheduling exists, the transmission unit is used for sending or receiving the dynamic scheduling data.

C. When the transmission direction of the transmission unit of the semi-persistent scheduling transmission configuration and the group common PDCCH configuration is the same, and no dynamically scheduled data exists, the transmission unit is used for transmitting or receiving the semi-persistent scheduled data.

D. When the group common PDCCH does not limit the transmission direction of the transmission unit, the transmission unit transmits or receives dynamic data or semi-persistent scheduling data according to the principle that the dynamic scheduling data has priority over the semi-persistent scheduling.

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

In particular, the data transmission performed by the transmission unit here is divided into: the uplink of the semi-persistent scheduling transmission indicates the uplink data transmitted by the UE to the base station; the downlink of the semi-persistent scheduling transmission refers to monitoring and receiving downlink data sent by the base station to the UE.

In this example, the base station determines a best transmission unit within a transmission time window to transmit the SPS based on semi-persistent scheduling. However, other transmission units within the transmission time window described in this example may be used to transmit SPS instead of other transmission units without dynamic scheduling conflicts.

In fig. 7, the uplink SPS transmission unit for semi-persistent scheduling is shown, and in fact, in conjunction with dynamic scheduling and semi-persistent scheduling, the uplink SPS transmitted by another transmission unit located within the transmission time window is selected.

In fig. 8, a downlink SPS transmission unit for semi-persistent scheduling is shown, and in fact, in conjunction with dynamic scheduling and semi-persistent scheduling, a downlink SPS transmitted by another transmission unit within the transmission time window is selected.
