Description

Scheduling indication method, terminal and network side equipment

Technical Field

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

Background

At present, in order to reduce power consumption of a terminal, an energy-saving scheme based on cross-slot (slot) scheduling is proposed in the field of communication technology. When the scheme is adopted, the terminal can acquire the transceiving time of a Physical Downlink Shared Channel (PDSCH)/a Physical Uplink Shared Channel (PUSCH) only after demodulating and decoding Downlink Control Information (DCI) used for scheduling, and then the terminal needs to configure higher processing performance so as to be able to process demodulation and decoding of the DCI in time.

Detailed Description

To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a system architecture diagram is shown in which an embodiment of the present invention is applicable. As shown in fig. 1, the system includes a terminal 11 and a network side device 12, and the terminal 11 and the network side device 12 communicate via a network.

Here, the terminal 11 may be a User Equipment (UE), such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). It should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited at all.

The network side device 12 may be a base station (i.e., eNB), for example, a macro station; alternatively, the network side device 12 may be a small station, such as a Low Power Node (LPN: Low Power Node) pico, femto, etc. It should be noted that, in the embodiment of the present invention, no limitation is imposed on the specific type of the network-side device 12.

Referring to fig. 2, a flowchart of a scheduling indication method according to an embodiment of the present invention is shown. As shown in fig. 2, the method is applied to a terminal, and the method includes the following steps:

receiving first scheduling energy-saving information sent by network side equipment at a first moment; the first scheduling energy-saving information is used for indicating a time slot scheduling type of the terminal in a first time window, the starting time of the first time window is later than or equal to a first time, and the time slot scheduling type is the current time slot scheduling type or a cross-time slot scheduling type.

Here, in the case where the slot scheduling type indicated by the first scheduling energy saving information is a cross-slot scheduling type, the first scheduling energy saving information may also be referred to as cross-slot scheduling energy saving information or cross-slot scheduling information.

Here, the first time window may be predefined, may be Radio Resource Control (RRC) configured, may be Medium access Control-Control element (MAC-CE) configured, or may be dynamically signaling configured.

It should be noted that the starting time and the ending time of the first time window may be the same time, and then the first time window represents one time; alternatively, the start time and the end time of the first time window may be different times, and then the first time window represents a time period. For convenience of understanding, in the embodiment of the present invention, a case where the first time window represents one time period is taken as an example for explanation.

In the embodiment of the invention, the terminal can receive first scheduling energy-saving information sent by the network side equipment at a first time, the first scheduling energy-saving information is used for indicating the time slot scheduling type of the terminal at a first time window, and the starting time of the first time window is later than or equal to the first time. Then, according to the first scheduling power saving information, the terminal may determine a slot scheduling type of itself in the first time window. If the timeslot scheduling type of the terminal in the first time window is a cross-timeslot scheduling type, in the first time window, after receiving the scheduling DCI each time, the terminal may immediately turn off a relevant device (e.g., a part of transceiver devices) to enter a sleep state, and in the sleep state, the terminal may demodulate and decode the scheduling DCI and determine when to exit the sleep state to receive data according to a demodulation and decoding result; if the time slot scheduling type of the terminal in the first time window is the time slot scheduling type, the terminal does not enter the dormant state in the first time window.

It should be noted that, in some cases, the scheduling type indicated by the scheduling energy saving information sent by the network side device to the terminal may be the current timeslot scheduling type, and in other cases, the scheduling type indicated by the scheduling energy saving information sent by the network side device to the terminal may be a cross timeslot scheduling type, that is, the network side device may send scheduling energy saving information indicating a corresponding timeslot scheduling type to the terminal according to an actual situation, which is beneficial to implement fast switching between current timeslot scheduling and cross timeslot scheduling, thereby further reducing power consumption of the terminal.

Optionally, the first scheduled power saving information is carried on the first power saving signal.

It is emphasized that the "first" of the first power saving signals does not constitute any limitation of the first power saving signals.

Here, the first power saving signal may carry related signaling information for power saving of the terminal, which may include at least one of: whether to wake up to monitor a Physical Downlink Control Channel (PDCCH), whether to sleep without monitoring the PDCCH, whether to monitor F PDCCH time units, whether to skip monitoring G PDCCH time units, whether to switch partial Bandwidth (BWP), whether to activate/deactivate a carrier, whether to configure a dormant secondary cell (dormant cell), whether to configure a Discontinuous Reception (DRX) parameter set, whether to configure PDCCH decoding (decoding) energy saving information, whether to configure a Radio Resource Management (RRM) energy saving function, and whether to trigger reference signal transmission and/or related measurement information reporting. The Scell may be referred to as a Secondary Cell or a Secondary Cell, in addition to being referred to as a Secondary Cell.

In this embodiment, by bearing the first scheduling energy-saving information on the first energy-saving signal, the transmission of the first scheduling energy-saving information between the network-side device and the terminal can be very conveniently achieved.

Optionally, the first scheduling power saving information is carried on the first DCI.

It is emphasized that "first" in the first DCI does not constitute any limitation of the first DCI.

Here, the first scheduling energy saving information may be carried by the first DCI by the configuration of the network side device. Specifically, the first DCI may be an existing DCI, which may be Broadcast DCI (i.e., closed DCI), group-common DCI, UE-specific DCI, or the like.

It should be noted that the existing DCI carries the cross-slot scheduling energy saving information, which may be configured periodically or non-periodically; the existing DCI carries the cross-slot scheduling energy saving information, which may be transmitted periodically or aperiodically. In addition, the DCI carrying the cross-slot scheduling energy saving information may carry the cross-slot scheduling energy saving information in a manner of newly adding a bit field, or may carry the cross-slot scheduling energy saving information in a manner of redefining the meaning of an existing bit field.

In this embodiment, by bearing the first scheduling energy-saving information on the first DCI, the transmission of the first scheduling energy-saving information between the network side device and the terminal can be very conveniently achieved.

Optionally, in a case that the first scheduling energy saving information is carried on the first DCI, the method further includes:

the second scheduling energy saving information is used for indicating a time slot scheduling type of the terminal in a second time window, the starting time of the second time window is later than or equal to a second time, and the second scheduling energy saving information is carried on the second energy saving signal.

Here, the second timing may be the same as or different from the first timing; the first time window and the second time window may be non-overlapping or overlapping in time.

In this embodiment, a part of the scheduling energy saving information may be carried on the existing DCI, and another part of the scheduling energy saving information may be carried on the energy saving signal, that is, there may be two types of carrying positions of the scheduling energy saving information, so that a suitable carrying position may be selected for the scheduling energy saving information according to an actual situation.

Optionally, the method further comprises:

under the condition that the first time window and the second time window are overlapped, selecting scheduling energy-saving information from the first scheduling energy-saving information and the second scheduling energy-saving information aiming at the overlapped area of the first time window and the second time window;

and taking the time slot scheduling type indicated by the selected scheduling energy-saving information as the time slot scheduling type of the terminal in the overlapping area.

Here, in the case where the first time window and the second time window overlap, the first scheduling energy saving information and the second scheduling energy saving information have a collision problem in an overlapping region of the first time window and the second time window. To solve the conflict problem, one scheduling energy saving information may be selected from the first scheduling energy saving information and the second scheduling energy saving information according to a predefined manner or according to a dynamically indicated manner. For example, the scheduled energy saving information having the closest reception time among the first scheduled energy saving information and the second scheduled energy saving information may be selected.

Then, the slot scheduling type indicated by the selected scheduling energy saving information may be used as the slot scheduling type of the terminal in the overlapping area.

Therefore, the embodiment can better solve the problem of conflict between scheduling energy-saving information.

Optionally, the first scheduling power saving information is carried on the first carrier and/or the first fractional bandwidth BWP, and the first scheduling power saving information is specifically used to indicate a slot scheduling type of the terminal on the second carrier and/or the second BWP in the first time window.

Here, the first carrier and the second carrier may be the same or different; and/or the first BWP and the second BWP may be the same or different.

In this embodiment, the carrier indicated by the scheduling power saving information may be different from the carrier carrying the scheduling power saving information, and the BWP indicated by the scheduling power saving information may be different from the BWP carrying the scheduling power saving information, so that the indication of the cross-carrier and/or cross-BWP slot scheduling type can be implemented.

determining a mapping relationship between active carriers in a first carrier and active carriers in a second carrier;

and/or the presence of a gas in the gas,

a mapping relationship between the active BWP in the first BWP and the active BWP in the second BWP is determined.

Here, the number of active carriers included in the first carrier may be one, two, three, or more than three, and the number of active carriers included in the second carrier may be one, two, three, or more than three, which are not listed here. It is noted that the number of active carriers included in the first carrier may be the same as or different from the number of active carriers included in the second carrier.

Here, the number of the active BWPs included in the first BWP may be one, two, three or more, and the number of the active BWPs included in the second BWP may be one, two, three or more, which are not listed herein. It should be noted that the number of active BWPs included in the first BWP may be the same as or different from the number of active BWPs included in the second BWP.

Here, the first rule for determining the mapping relationship between the activated carriers and the second rule for determining the mapping relationship between the activated BWPs may be configured in a predefined manner, an RRC signaling manner, a MAC-CE notification manner, or a dynamic signaling manner. Thus, according to the first rule, a mapping relationship between the activated carrier in the first carrier and the activated carrier in the second carrier can be determined, and the mapping relationship can be one-to-many mapping, many-to-one mapping, or one-to-one mapping, etc.; according to the second rule, a mapping relationship between the active BWP in the first BWP and the active BWP in the second BWP may be determined, and the mapping relationship may be a one-to-many mapping, a many-to-one mapping, or a one-to-one mapping, etc.

After the above determining operation is performed according to the first rule and/or the second rule, a corresponding mapping relationship may be obtained, and according to the mapping relationship, it can be known to which active carriers and/or which active BWPs are specifically pointed by the timeslot scheduling type indicated by the first scheduling energy saving information, so as to perform subsequent operations.

the method further comprises the following steps:

and determining the time slot scheduling type of the terminal in the first time window according to the time slot scheduling type identifier.

Here, the slot scheduling type identifier in the first scheduling energy saving information may be a character identifier, for example, the present slot scheduling type identifier (which corresponds to the present slot scheduling type) may be represented by 0, and the cross slot scheduling type identifier (which corresponds to the cross slot scheduling type) may be represented by 1. In this way, under the condition that the timeslot scheduling type identifier in the first scheduling energy-saving information is 0, the timeslot scheduling type of the terminal in the first time window may be determined as the timeslot scheduling type; in the case that the slot scheduling type identifier in the first scheduling energy saving information is 1, the slot scheduling type of the terminal in the first time window may be determined as a cross-slot scheduling type.

It can be seen that, the time slot scheduling type of the terminal in the first time window can be determined very conveniently in this embodiment.

a time interval from the second DCI transceiving to the PDSCH transceiving;

a time interval from the second DCI transceiving to the PUSCH transceiving;

a time interval from the Channel-State Information reference signal (CSI-RS) transceiving to the second DCI transceiving;

a time interval from the sending of the uplink Sounding Reference Signal (SRS) to the sending of the second DCI;

a minimum time interval between SRS transceiving and second DCI transceiving;

the method further comprises the following steps:

and determining the time slot scheduling type of the terminal in the first time window according to the time interval in the first scheduling energy-saving information.

Here, the second DCI may specifically be a scheduling DCI; the CSI-RS may be an aperiodic CSI-RS.

It should be noted that, the time interval between the second DCI transceiving and the PDSCH transceiving represents a specific time interval; the minimum time interval between the second DCI transceiving to the PDSCH transceiving represents a minimum time interval, that is, the time interval between the second DCI transceiving to the PDSCH transceiving may be greater than or equal to the minimum time interval. The meaning of other time intervals can refer to the above description, and are not described herein again.

It is noted that for any of the time intervals described above, it may be slot-granular, symbol-granular, or subframe-granular.

Assuming that the first scheduling energy-saving information includes a time interval between the transmission and reception of the second DCI and the transmission and reception of the PDSCH (assuming that the time interval is T time slots), a time slot value (for example, 0 time slot) may be stored in the terminal in advance, and when T is equal to 0, it may be determined that the time slot scheduling type of the terminal in the first time window is the present time slot scheduling type; in the case that T is greater than 0 (e.g., 1 or 2), it may be determined that the slot scheduling type of the terminal in the first time window is the cross-slot scheduling type.

It should be noted that, in the case that the first scheduling energy saving information includes the at least one time interval, and the first time window represents one time, the idea of the scheduling indication method in this embodiment may be described as: indicating the time interval of the cross-slot scheduling in the scheduling DCI at the Mth time through the DCI which bears the cross-slot scheduling information at the Nth time; wherein the Mth time is not earlier than the Nth time.

alternatively, the first and second liquid crystal display panels may be,

As can be seen, in this embodiment, according to the time interval in the scheduling energy-saving information, the DCI in the corresponding DCI format may be used to carry the scheduling energy-saving information, so that transmission of the scheduling energy-saving information can be better ensured.

It should be noted that, at present, a scheme for reducing power consumption of a terminal by using cross-slot scheduling is proposed in a UE energy saving problem of a New Radio (NR) 16WI, and specifically, if the UE knows an interval of a slot scheduled in advance, the UE may enter a slot after receiving a PDCCH, wait until a PDSCH receiving time, and then turn on a relevant device to receive a PDSCH, thereby reducing power consumption. Further, in a Radio Access Network (RAN) 196bis conference, a DCI-based is proposed as a power saving signal/channel (power saving signal/channel) to indicate an energy saving scheme of the UE, wherein MAC-CE is not excluded, and how to indicate cross-slot scheduling of the UE based on this, so that the UE can turn off some devices after receiving a PDCCH, enter a sleep state, and further research is required.

In the existing energy-saving scheme of the cross-slot-based scheduling UE, the UE knows cross-slot scheduling before demodulating the PDCCH, so that the UE can reduce power consumption for PDCCH processing through lower power consumption device processing capability, and can avoid extra invalid power consumption caused by invalid PDSCH buffering, and even the UE can turn off part of the devices and enter a sleep state. Based on the above analysis, the UE can reduce the power consumption of the terminal through cross-slot scheduling, and thus is one of the main directions of WI research.

It should be noted that, in current scheduling based on cross-slot, information of the cross-slot indicates K0 and K2 through a TDRA table (which is specifically located in scheduling DCI), and K0 indicates a slot interval between DCI transceiving and PDSCH transceiving; the K2 indicates a slot interval between DCI transmission and reception to PUSCH transmission and reception. After receiving the DCI (which is specifically the scheduling DCI), the UE can acquire the K0 and K2 information only after completing demodulation and decoding of the scheduling DCI. In addition, the transmission of aperiodic a-CSI-RS is currently based on RRC signaling semi-static configuration. Based on the prior art, the UE can know the transceiving time of the PDSCH/PUSCH only after demodulating and decoding DCI, so that the UE needs to configure higher processing performance to process the demodulation and decoding of the scheduling DCI in time; on the other hand, before obtaining DCI bit domain information by demodulation and decoding, the UE cannot judge the time of PDSH/PUSCH reception and transmission, and needs to buffer the PDSCH/PUSCH all the time, thereby consuming higher power consumption; moreover, since the UE does not know the time of PDSCH/PUSCH transmission and reception, some devices of the UE cannot be turned off in time, which also results in higher power consumption.

Furthermore, in the prior art, the energy saving scheme of the UE includes cross slot scheduling, and the RAN196bis conference is passed through, and may be indicated by a DCI-based energy saving signal, or may be indicated by a MAC-CE. If a design based on DCI-based power saving signal is considered, the design can be based on a new DCI format, and the design can be based on an existing DCI with a new bit field added. Therefore, the design based on the DCI-based power saving signal and the design based on the existing DCI newly added bit field, how to indicate the scheduling information of cross-slot, so that the UE can reduce the power consumption needs further research.

Finally, multi-carrier or multiple BWP configurations are important functional features in NR. Based on this, when there are multiple carriers or multiple BWPs configured, in the current technology, cross scheduling information of the BWPs configured with multiple carriers is configured through the MAC-CE, which has a major problem of large delay. When there is a fast change due to a service requirement, and switching between the local slot scheduling and the cross-slot scheduling is required, the switching cannot be completed fast.

It is easy to see that, in the prior art, the parameters K0 and K2 related to the cross-slot scheduling are configured by scheduling DCI, and before the scheduling DCI is demodulated, the UE cannot know whether the scheduling DCI is the local slot scheduling or the cross-slot scheduling, so that the UE needs to adopt a high-performance processing device to complete the demodulation and decoding of the scheduling DCI as soon as possible, and continuously buffer the PDSCH/PUSCH, and cannot turn off part of the transceiving devices of the terminal, thereby bringing greater power consumption to the terminal. Further, the slot interval for transmitting the a-CSI-RS is configured semi-statically through RRC signaling, and cannot support fast handover between cross-slot scheduling and local slot scheduling.

In view of this, the present solution may provide a scheduling indication method from the perspective of the base station and the terminal; wherein the content of the first and second substances,

the specific flow of the scheduling indication method at the base station side is as follows:

step 1: the base station configures cross-slot scheduling energy-saving related information.

Step 2: the base station transmits energy saving information scheduled across time slots.

And step 3, optionally, the base station sends scheduling information.

And 4, the base station sends the first data information or receives the second data information.

The specific process of the scheduling indication method at the terminal side is as follows:

step 1: the terminal receives cross-slot scheduling power saving information.

And 2, step: optionally, the terminal receives the scheduling information.

And 3, step 3: the terminal sends the first data information, or the terminal receives the second data information.

The following describes a specific implementation procedure of the scheduling indication method at the base station side in several specific embodiments.

Step 1: the base station configures cross-slot scheduling energy-saving related information. Specifically, the method comprises the following steps:

scheduling power saving information across time slots, comprising at least one of: a first time interval between DCI transceiving to PDSCH transceiving; a second time interval from DCI transceiving to PUSCH transceiving; a third time interval from the aperiodic CSI-RS transceiving to the DCI transceiving; a fourth time interval from SRS transceiving to DCI transceiving; a minimum time interval from DCI transceiving to PDSCH transceiving, that is, a fifth time interval; a sixth time interval, which is a minimum time interval from DCI transceiving to PUSCH transceiving; a minimum time interval from the non-periodic CSI-RS to the DCI transceiving, namely a seventh time interval; a minimum time interval from SRS transceiving to DCI transceiving, that is, an eighth time interval; the time interval from DCI transceiving to PU/DSCH transceiving or the minimum time interval, namely the ninth time interval; a time interval or a minimum time interval between the receiving and sending of DCI to PU/DSCH and a time interval or a minimum time interval between the receiving and sending of aperiodic CSI-RS to the receiving and sending of DCI, namely a tenth time interval; the time interval or the minimum time interval between the DCI transceiving to the PU/DSCH, the time interval or the minimum time interval between the aperiodic CSI-RS transceiving to the DCI transceiving, and the time interval or the minimum time interval between the SRS transceiving to the DCI transceiving, namely the eleventh time interval. Any of the above time intervals may be equal to or different from other time intervals.

The time interval may be a slot granularity, a symbol granularity, a subframe granularity, or a predetermined time granularity.

The base station configuration may be based on an existing DCI type bearer. The existing DCI may be Broadcast DCI, group-common DCI, or UE-specific DCI.

Broadcast DCI: the scheduling information used for indicating all the UEs in a cell includes DCI format0-0 for uplink scheduling and DCI format 1-0 for downlink scheduling. For the DCI for scheduling broadcast information, only basic scheduling information is needed to ensure high reliability.

Group-common DCI: the scheduling information used for indicating a plurality of UE groups in a cell corresponds to DCI format2-0, DCI format2-1, DCI format 2-2 and DCI format 2-3. The DCI format2 series is used to transmit control information of a group of terminals, and includes DCI format2-0, DCI format2-1, DCI format 2-2 and DCI format 2-3. The DCI format2-0 is used for transmitting the indication information of the time slot structure, the DCI format2-1 is used for transmitting PI information, and the DCI format 2-2 is used for transmitting the power control information of the PUSCH or PUCCH;

the DCI format 2-3 is used for SRS power control and SRS request. The UE-specific DCI comprises fallback DCI and Non-fallback DCI, and part of information domains in the Non-fallback DCI can be configured through high-level signaling. In addition, since there are no more Transmission Modes (TM) in the NR, the non-fallback includes only the DCI format0-1 for uplink scheduling and the DCI format 1-1 for downlink scheduling.

The cross-slot scheduling information may be carried in at least one DCI format. For example, the first time interval, the fifth time interval, the ninth time interval, the tenth time interval, and the eleventh time interval may be carried in a Downlink (DL) DL DCI format, for example, in DL DCI, such as DCI format 1-0, DCI format 1-1, and also DCI format2-0, DCI format 2-1. For another example, the second time interval, the third time interval, the fourth time interval, the sixth time interval, the seventh time interval, the eighth time interval, the ninth time interval, the tenth time interval, and the eleventh time interval may be carried in an Uplink (UL) DCI format, for example, in UL DCI, such as DCI format0-0, DCI format0-1, DCI format 2-2, and DCI format 2-3.

The existing DCI carries cross-slot scheduling information, which may be configured periodically or non-periodically. Taking fig. 3 and fig. 4 as examples, in the diagrams, the first DCI may represent a DCI carrying cross-slot scheduling information, and the fourth DCI may represent a DCI carrying scheduling information other than the cross-slot scheduling information, where the first DCI and the fourth DCI may be the same DCI or different DCIs.

The DCI carrying the cross-slot scheduling information at the nth time indicates a time interval of cross-slot scheduling in the scheduling DCI at the mth time, where the time interval is as described above, and the mth time is not earlier than the nth time.

The DCI carrying the energy-saving information for cross-slot scheduling may be a method of carrying the energy-saving information for cross-slot scheduling by newly adding a bit field, or a method of redefining the meaning of an existing bit field. The new bit field addition manner may be to use {0, 1.... K } bits to represent the energy saving information of the cross-slot scheduling, wherein the number of the time intervals that may be indicated does not exceed 2K, K0, 1.... K, or the number of the index of the time interval that may be indicated does not exceed 2K, K0, 1.... K.

Step 2: the base station sends cross-time-slot scheduling energy-saving information, specifically:

the cross-slot scheduling energy saving information may be periodically transmitted, and a period of the first DCI carrying the cross-slot scheduling energy saving information and a period of the fourth DCI carrying other scheduling information may be the same, for example, a DCI of the cross-slot scheduling information used to indicate a time interval from a DCI to a PDSCH may be the same as or different from an existing fourth DCI period used for PDSCH scheduling, for example, a period of the first DCI may be a multiple of a period of the fourth DCI.

The energy saving information scheduled across time slots may be transmitted aperiodically. The scope window of the DCI of the energy saving information scheduled across the time slots may be statically configured, semi-statically configured, for example, RRC signaling configuration, or dynamically configured, for example, MAC-CE, PDCCH, power saving signal, and the like. The scope window represents a time window within which energy saving information scheduled across time slots is the same.

And step 3, optionally, the base station sends scheduling information.

The DCI carrying the scheduling information and the DCI carrying the energy saving information scheduled in the cross-slot may be the same DCI bearer, and this step may be skipped over; if it is carried on a different DCI, this step is performed.

The first data information may be downlink data carried on the PDSCH, which may be a reference signal or a pilot signal, for example, an aperiodic CSI-RS; the second data information may be uplink data carried on a PUSCH, and may be a reference signal, a pilot signal, such as an SRS.

Example 2: the cross-time slot scheduling energy saving information is indicated by an energy saving signal;

the same procedure as in example 1, except that:

the energy-saving signal may carry signaling information related to terminal energy saving, and the signaling information may include at least one of whether to wake up to monitor a PDCCH, whether to sleep without monitoring the PDCCH, whether to monitor F PDCCH time units, whether to skip monitoring G PDCCH time units, whether to switch BWP, whether to activate/deactivate a carrier, whether to configure a dormant Scell, whether to configure a DRX parameter set, whether to configure PDCCH decoding energy-saving information, whether to configure an RRM energy-saving function, whether to trigger reference signal transmission and/or related measurement information reporting.

The concrete procedure is the same as example 1, step 2. Further, in the above-mentioned case,

the power saving signal carries cross-slot scheduling power saving information, and the scope of the cross-slot scheduling power saving information may be semi-statically configured, for example, RRC signaling configuration, or may be dynamically configured, for example, DCI configuration, or MAC-CE configuration.

The energy saving signal carries the cross-time-slot scheduling energy saving information, and the scope of the energy saving signal can be the same as or different from the scope of other energy saving information except the cross-time-slot scheduling energy saving information. For example, the scope of the cross-slot scheduling energy saving information may be N to N +5 time slots in fig. 5, and the scope of the other energy saving information may be N to N +3 time slots in fig. 5, so that the same energy saving information configuration may be adopted in all the N to N +5 time windows, and the same cross-slot scheduling information may be adopted in all the N to N +3 time windows. Of course, the scope of scheduling energy saving information across time slots and the scope of other energy saving information may also be both N to N +5 time slots in fig. 3. It should be noted that the bearer for scheduling energy saving information across timeslots may be an energy saving signal or DCI, and the bearers for other energy saving information may also be energy saving signals or DCI.

And step 3, optionally, the base station sends scheduling information.

The concrete procedure is the same as example 1, step 3.

The concrete procedure is the same as in step 4 of example 1.

Example 3: the cross-time slot scheduling energy-saving information is indicated by an energy-saving signal and/or an existing DCI format;

the same as step 1 in example 1 and step 2 in example 1. The energy saving signal, the existing DCI, is the same as the previous description.

The difference lies in that:

the base station configures the cross-slot scheduling energy-saving information, and the cross-slot scheduling energy-saving information can be carried in an existing DCI format and can be carried on an energy-saving signal. The cross-slot scheduling energy saving information is carried in an existing DCI format and on an energy saving signal, and may be predefined, configured by RRC signaling, configured by MAC-CE, and configured by dynamic signaling.

The cross-slot scheduling energy saving information may be carried on the existing DCI in the first time window, may be carried on the energy saving signal in the second time window, and may be carried on the existing DCI and the energy saving signal in the third time window.

The first time window, the second time window, and the third time window may be non-overlapping, or partially overlapping in time.

The first time window, the second time window, and the third time window may be predefined, may be RRC-configured, may be MAC-CE-configured, and may be dynamically signaled.

The first time window, the second time window, and the third time window may be in a DRX cycle granularity, a slot granularity, a symbol granularity, or a predefined time granularity.

The first time window may be the same as the energy saving information scheduled across the time slot; the second time window, the energy saving information scheduled across the time slots, may be the same; the third time window, the energy saving information scheduled across time slots, may be the same. If the first time window, the second time window and the third time window are overlapped or partially overlapped, the energy-saving information scheduled by crossing time slots in the overlapped time windows can cause a conflict problem. In order to solve the conflict problem, a predefined manner or a dynamic indication manner may be adopted, for example, a base station may predefine a rule, for example, if a conflict occurs, the indication may be performed in accordance with an indication manner of predefined energy saving information scheduled across time slots; for another example, the energy saving information indication of the cross-slot scheduling closest to the terminal receiving the scheduling DCI may be used.

Example 4: indication of cross-slot scheduling of energy saving information under multi-carrier/multi-BWP

Specifically, the same procedure as in step 1 of example 1, example 2 and example 3 was repeated. The difference lies in that:

the cross-slot scheduling energy saving information is carried in fifth information/signaling, where the fifth information/signaling may be existing DCI and/or energy saving signal DCI. The fifth information/signaling is carried on a first carrier and/or first BWP information, the first carrier including at least one activated carrier information, and the first BWP information including at least one activated BWP information. The activated carrier information may be data transceiving, signaling transceiving, reference signal transceiving on the carrier; the activated BWP information may be data transceiving, signaling transceiving, or reference signal transceiving on the BWP.

The energy saving information scheduled across time slots indicates a second carrier and/or second BWP information, where the second carrier includes at least one activated carrier information, and the second BWP information includes at least one activated BWP information.

The relationship between the first carrier, the first BWP information, the second carrier information, and the second BWP information may be at least one of the following relationships, including the first carrier information and/or the first BWP information, and the second carrier information and/or the second BWP information, which may be the same or different; the first BWP information may be the same as, and may be different from, the second BWP information; the first carrier information may be the same as or different from the second carrier information.

The number of the first carriers activated by the first carrier information, the number of the second carriers activated by the second carrier information, and the number of the first carriers may be smaller than the number of the second carriers, so that the mapping of the indication relationship from the first carrier information to the second carrier information may be one-to-many mapping, and the mapping relationship may be predefined, may be notified by RRC signaling, may be notified by MAC-CE, or may be notified by dynamic signaling. For example, if the number of first carriers is equal to X, including { X1, X2}, and the number of indicated second carriers is equal to Y, including { Y1, Y2, Y3}, the mapping relationship may be: x1 is mapped as Y1, X2 is mapped as Y2, Y3; alternatively, the mapping relationship may be: x2 maps to Y1, Y2, Y3.

The number of the first carriers activated by the first carrier information and the number of the second carriers activated by the second carrier information may be greater than the number of the second carriers, and then the mapping of the indication relationship of the first carrier information to the second carrier information may be a many-to-one mapping, and the mapping relationship may be predefined, may be notified by RRC signaling, may be notified by MAC-CE, or may be notified by dynamic signaling. For example, if the number of first carriers is equal to X, including { X1, X2, X3}, and the number of indicated second carriers is equal to Y, including { Y1, Y2, Y3}, then the mapping relationship may be: x1 maps to Y1, X2 maps to Y2, Y3, Y3; alternatively, the mapping relationship may be: x1 maps to Y1, Y2, Y3.

The number of the first carriers activated by the first carrier information and the number of the second carriers activated by the second carrier information may be equal to the number of the second carriers, the number of the carriers is the same, and the number of the corresponding carriers activated by the first carrier information may be different from the number of the corresponding carriers activated by the second carrier information. The mapping of the indication relationship of the first carrier information to the second carrier information may be one-to-one mapping, may be one-to-many mapping, may be many-to-one mapping, and the mapping relationship may be predefined, may be RRC signaled, may be MAC-CE signaled, and may be dynamically signaled. Specific examples are as described above.

It should be noted that the mapping relationship between the first carrier information and the second carrier information may be specifically as shown in fig. 6.

The number of the first BWP, the number of the second BWP, and the mapping relationship, such as the number of the first carrier activated by the first carrier information and the number of the second carrier activated by the second carrier information, are the same, and the numerical relationship and the mapping relationship are not described herein again.

The following describes in detail a specific implementation procedure of the scheduling indication method at the terminal side in several specific embodiments.

Example 5: the cross-slot scheduling power saving information is indicated by an existing DCI format.

Step 1: the terminal receives cross-slot scheduling energy saving information. Specifically, the procedure was as in example 1, step 1 and step 2.

Step 2: optionally, the terminal receives the scheduling information. Specifically, the procedure was as in step 3 of example 1.

And step 3: and the terminal sends the first data information or receives the second data information. Specifically, the procedure was as in step 4 of example 1.

Example 6: the cross-slot scheduling power saving information is indicated by a power saving signal.

Step 1: the terminal receives cross-slot scheduling power saving information. Specifically, the procedure was as in example 2, step 1 and step 2.

Step 2: optionally, the terminal receives the scheduling information. Specifically, the procedure was as in step 3 of example 2.

And step 3: the terminal sends the first data information, or the terminal receives the second data information. Specifically, the procedure was as in step 4 of example 2.

Example 7: the cross-time slot scheduling energy-saving information is indicated by an energy-saving signal and/or an existing DCI format;

step 1: the terminal receives cross-slot scheduling power saving information. Specifically, the procedure was as in step 1 and step 2 of example 3.

Step 2: optionally, the terminal receives the scheduling information. Specifically, the procedure was as in step 3 of example 3.

And step 3: the terminal sends the first data information, or the terminal receives the second data information. Specifically, the same procedure as in step 4 of example 3 was repeated.

Example 8: scheduling an indication of energy saving information under multi-carrier/multi-BWP across time slots;

step 1: the terminal receives cross-slot scheduling power saving information. Specifically, the procedure was as in step 1 and step 2 of example 4.

Step 2: optionally, the terminal receives the scheduling information. Specifically, the procedure was as in step 3 of example 4.

And step 3: the terminal sends the first data information, or the terminal receives the second data information. Specifically, the procedure was as in step 4 of example 4.

It can be seen that the main idea of the scheduling indication method provided in the foregoing embodiments 1 to 8 is to carry the first information/signaling, that is, the energy saving information of cross-slot scheduling, through the energy saving signal or the design of the existing DCI information domain. The cross-slot scheduling energy saving information may be carried on the existing DCI in the first time window, may be carried on the energy saving signal in the second time window, and may be carried on the existing DCI and the energy saving signal in the third time window. The first time window, the second time window, and the third time window may be non-overlapping, or partially overlapping in time. The DCI carrying the cross-slot scheduling information at the Nth time indicates the time interval of the cross-slot scheduling in the scheduling DCI at the Mth time, and the time interval is as described above. The first information/signaling may be carried on first carrier information and/or first BWP information, and the energy saving information scheduled across timeslots indicated by the first information/signaling may indicate second carrier information and/or second BWP information. The first carrier information comprises at least one activated carrier information; the first BWP information including at least one activated BWP information; the second carrier information comprises at least one activated carrier information; the second BWP information includes at least one activated BWP information. The first carrier information and/or the first BWP information may be the same as or different from the second carrier information and/or the second BWP information; the first BWP information may be the same as or different from the second BWP information; the first carrier information may be the same as or different from the second carrier information. The number of the first carriers activated by the first carrier information and the number of the second carriers activated by the second carrier information may be smaller than, equal to, or larger than.

By adopting the above scheme, the time interval of the cross-slot scheduling in the DCI at the M time can be indicated through the DCI carrying the cross-slot scheduling information at the N time, and the time interval is as described above, wherein the M time is not earlier than the N time, so that the UE can know the cross-slot scheduling information before demodulating and decoding the DCI, thereby turning off the related equipment, or reducing the processing power consumption of the equipment, and further reducing the power consumption of the UE. In addition, the fast switching between the time slot scheduling and the cross time slot scheduling can be realized in a dynamic signaling mode, so that the power consumption of the UE can be reduced.

Therefore, in the embodiment of the present invention, through the timeslot scheduling type indicated by the scheduling energy saving information, before the DCI is demodulated, decoded and scheduled, the terminal can recognize that the terminal can enter the sleep state, and turn off the relevant device, so as to reduce the power consumption of the terminal.

Optionally, the first scheduling energy saving information is carried on the first downlink control information DCI.

Optionally, the method further comprises:

Optionally, the first scheduling energy-saving information is carried on the first carrier and/or the first fractional bandwidth BWP, and the first scheduling energy-saving information is specifically used to indicate a timeslot scheduling type of the terminal on the second carrier and/or the second BWP in the first time window.

the first scheduling energy-saving information is used for indicating a time slot scheduling type of the terminal in a first time window, the starting time of the first time window is later than or equal to a first time, and the time slot scheduling type is the current time slot scheduling type or a cross-time slot scheduling type.

It can be seen that, in the embodiment of the present invention, through the timeslot scheduling type indicated by the scheduling energy saving information, before demodulating and decoding the scheduling DCI, the terminal 800 can identify a condition that the terminal 800 can enter the sleep state, and turn off the relevant device, so as to reduce the power consumption of the terminal 800, therefore, compared with the prior art, the effect of the scheme for reducing the power consumption of the terminal 800 in the embodiment of the present invention is better.
