Description

A method for transmitting indication signaling, base station and terminal

technical field

The present invention relates to the technical field of wireless communication, and in particular, to a method for transmitting indication signaling, a base station and a terminal.

Background technique

In order to satisfy users with richer service experience and smoother network usage experience, 5G introduces larger bandwidth, more antennas, and allows more optional network configurations in system design, but these also bring greater Terminal power consumption. If an effective terminal energy-saving design cannot be introduced to ensure the terminal's use time, the introduction of terminal services will be greatly restricted, and the user's NR (New Radio) network and terminal use experience will be affected. On the other hand, the ITU (International Telecommunication Union) has defined higher energy efficiency indicators for 5G. The high energy efficiency of the terminal is reflected in: 1) In the process of data transmission, more efficient transmission efficiency is adopted; 2) When there is no data transmission , with lower energy consumption. Both the 5G deployment requirements and performance indicators have put forward requirements on the energy consumption of the terminal, and based on this R16, the terminal energy-saving project has been established.

The research goal of the project is to consider the energy-saving design of the terminal on the basis of taking into account the delay and system performance. The research content focuses on the following two aspects in the physical layer:

●Research on energy-saving technology under RRC (Radio Resource Control, Radio Resource Control) connection state, conduct research on adaptive energy-saving transmission based on user service type, involving frequency domain dimension, time domain dimension, antenna dimension, DRX (Discontinuous Reception, non- Design of energy-saving signals, channels, and processes to adapt to user service types in terms of continuous reception) parameter configuration, user time processing capabilities, and other aspects.

• Terminal energy saving design for RRM (Radio Resource Management) measurements in synchronous and asynchronous networks. Work involving RAN1 and RAN2.

From the energy consumption statistics of LTE (Long Term Evolution) terminals, more than half of the terminal power consumption occurs in the terminal RRC_CONNECTED (RRC connection) state, and in most cases, the terminal does not receive valid data scheduling after detection. Or only a small amount of data is scheduled. At this time, if the frequency at which the terminal performs control channel detection or the bandwidth for data reception can be reduced, the power consumption of the terminal can be effectively saved. Therefore, it is very meaningful for the physical layer to focus on the energy-saving design of the connection state from several power consumption-leading elements in the connection state, such as bandwidth, the number of activated RF chains (radio frequency links), and the activation time.

In the prior art, in the enhancement technology of NB-IOT (Narrow Band Internet of Things, Narrow Band Internet of Things), the design of energy saving and the design of the wake-up signal of IDLE (idle state) have been considered. signal, wake-up signal) indicates whether a valid paging message is sent at the paging time of the terminal. If no valid paging message is sent, the terminal does not need to detect the control channel for scheduling the paging message, and can continue to maintain the low power consumption mode to achieve Energy saving effect.

The WUS signal adopts a ZC sequence with a length of 131 and carries the cell ID. The maximum time domain duration of the WUS is configured by the upper layer, and the gap (gap) between the WUS and the PDCCH scheduling the paging message is configured, as shown in Figure 1. Since NB-IOT is a narrowband system, WUS occupies the entire bandwidth of NB-IOT in the frequency domain, and occupies one subframe, ie, 1 ms, in the time domain.

The WUS design in the NB is mainly used to solve the energy consumption problem of the IDLE state user detecting invalid PDCCH. For NR, the energy-saving technology of the physical layer focuses on the energy-saving technology of the connected state. In addition, the design of WUS occupying the entire bandwidth of the system and the entire subframe is no longer applicable, and the system bandwidth of NR will be as large as several hundred megabytes, and occupying the entire bandwidth is obviously too expensive. For the connected state, the scheduling frequency of the control channel is at the slot level. The paging cycle in the idle state is in the order of tens or hundreds of milliseconds. If a time slot level is added for each control channel scheduling (the time domain scheduling unit of LTE is a subframe, which includes 14 OFDM symbols with a 15KHz subcarrier interval, the time domain scheduling unit of NR is a time slot or a mini-slot, a The wake-up signal overhead of the time slot regardless of the sub-carrier spacing includes 14 OFDM symbols) will also be unbearable. On the other hand, the control channel detection complexity in the NR connected state comes from various aspects, such as the frequency of detection, the number of control channel candidates detected, and the bandwidth of detection. The WUS design in the NB-IOT system only needs to indicate whether the PDCCH of the paging channel needs to be detected.

DRX technology is a terminal energy-saving technology that can be used in the connected state. The configuration of DRX in the connected state in NR is carried out through high-level signaling, and a series of timer (timer) parameters of the terminal are configured, such as on duration timer (active period timer), inactivity timer (inactive period timer), uplink and downlink HARQ-RTT timer (discontinuous reception-hybrid automatic repeat request-round-trip time timer), uplink and downlink retransmission timer (retransmission timer), long and short DRX cycle settings, initial time slot offset settings, time slot offset ( Offset) settings, etc., the user performs the transition between the active state and the DRX state based on these high-level parameter configurations. Based on these configurations it is determined when the terminal is in the active period. The PDCCH is only detected during the activation period, and the PDCCH may not be detected at other times to achieve the purpose of energy saving.

However, the configuration of the DRX in the connected state is performed through high-level signaling, and the adjustment of configuration information is not flexible, and the energy-saving effect cannot quickly adapt to the service type of the terminal.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for transmitting indication signaling according to Embodiment 1 of the present invention. The method for transmitting indication signaling is applied to a base station, including:

Step 21: Send an indication signaling on the designated transmission resource, the designated transmission resource is determined by the time domain and/or frequency domain resources for transmitting the SSB (SS/PBCH Block, synchronization signal/physical broadcast channel block), and the indication signaling Indicates at least one of the following information:

In this embodiment of the present invention, the transmission resource of the indication signaling is determined by the time domain and/or frequency domain resources for transmitting the SSB, that is, the transmission resource of the indication signaling and the transmission resource of the SSB have a definite positional relationship, because the SSB is sent periodically , so the indication signaling is also sent periodically, thereby improving the flexibility of the configuration of the DRX in the connected state and achieving the purpose of more effective energy saving.

The SSB in the embodiment of the present invention may be all the SSBs sent by the base station, or may be the SSB at a specified location.

In addition, in this embodiment of the present invention, the instruction instruction may indicate the activation state in the next at least one DRX cycle, the configuration of DRX parameters in at least one DRX cycle, the detection state of the PDCCH, and the detection state of the next at least one paging occasion , which can indicate more and more flexible content.

The transmission method of the indication signaling and the indication content of the indication signaling are described in detail below.

1. Transmission mode of instruction signaling

In this embodiment of the present invention, the transmission resources of the indication signaling are determined by the time domain and/or frequency domain resources for transmitting the SSB, that is, the transmission resources of the indication signaling and the transmission resources of the SSB have a definite positional relationship.

The following first describes the transmission method and carried content of the SSB.

The transmission period of SSB can be configured as {5, 10, 20, 40, 80, 160} ms. An SSB in the time domain contains 4 OFDM symbols, and in the frequency domain, it contains 240 consecutive sub-carriers. According to the current design of NR, in the SSB The subcarriers used to transmit PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), PBCH (Physical Broadcast Channel) and DM-RS (Demodulation Reference Signal) are shown in the table below (from 38.211). That is, the sequences of PSS and SSS are transmitted on a total of 127 subcarriers from subcarriers 56 to 182 of the first and third OFDM symbols (the corresponding symbol indices are 0, 2). The PBCH is transmitted on the 2nd and 4th OFDM symbols, and at the same time, it is transmitted on the 3rd OFDM symbol, that is, the 96 sub-carriers of No. 0 to 47, 192 to 239 on both sides of the SSS. In the table, v represents the shift of the subcarriers mapped by the DM-RS.

Table 1: Resources occupied by PSS, SSS, PBCH and DM-RS in an SSB (Resources within an SS/PBCH block for PSS, SSS, PBCH, and DM-RS for PBCH)

In some embodiments of the present invention, optionally, the designated transmission resource of the indication signaling may be located in an OFDM (Orthogonal Frequency Division Multiplexing) symbol for transmitting the SSB.

As can be seen from the above table, among the four symbols of SSB, the same subcarrier position on the first OFDM symbol (the corresponding symbol index is 0) corresponding to the third OFDM symbol for transmitting PBCH is set to 0 ( That is, Set to 0) in the table, therefore, the above-mentioned set to 0 position can be used as the designated transmission resource of the indication signaling. That is, the designated transmission resource may be located in the first OFDM symbol of the SSB.

Referring to FIG. 3, in some embodiments, the designated transmission resources may be located on both sides of the frequency domain resources of the PSS in the first OFDM symbol, and the subcarriers used for transmission are the same as the third OFDM of the SSB. The subcarriers on which the PBCH is transmitted on the symbols are the same.

In the embodiment of the present invention, the indication signaling is carried on the sub-carrier set to 0 of the SSB, which can fully utilize the time-frequency domain resources, and does not require additional allocation resources, thereby avoiding resource fragmentation.

Referring to FIG. 4 , in some other embodiments, the designated transmission resource may also be located on the side of the frequency domain resource of the PSS in the first OFDM symbol, wherein part of the frequency domain resource of the designated transmission resource is the same as that of the SSB. The partial frequency domain resources of the first OFDM symbol are the same.

Certainly, in some other embodiments of the present invention, optionally, the designated transmission resource may also be located in an OFDM symbol adjacent to the OFDM symbol of the SSB.

In the embodiment of the present invention, the sending the indication signaling on the designated transmission resource includes:

The indication signaling is encoded by channel coding, or repetition coding, or a coding manner in which information bits and coded bits have a mapping relationship;

sending the encoded indication signaling on the designated transmission resource;

or,

The indication signaling is carried by a sequence;

The sequence is sent on the designated transmission resource.

The indication signaling for different terminals can be distinguished by different orthogonal codes and transmitted on the same transmission resource.

2. Indication content of instruction signaling

In the above-mentioned embodiment, the one-to-one indication signaling may indicate the first information, the second information, the third information and/or the fourth information, which will be described separately below.

1. The first information is used to indicate the activation state in the next at least one DRX cycle

In this embodiment of the present invention, the first information indicating the activation state in the next at least one DRX cycle includes:

a) Indicate the time position that satisfies the constraint relationship between the drx-ShortCycle (discontinuous reception-short cycle) and drx-StartOffset (discontinuous reception-start offset) parameters in the next at least one DRX cycle, and/or, The time position that satisfies the constraint relationship between drx-LongCycle (discontinuous reception-long cycle) and drx-StartOffset (discontinuous reception-slot offset) parameters, and/or, satisfies drx-SlotOffset (discontinuous reception-slot offset) ) The time position constrained by the parameter, whether to start drx-onDurationTimer (discontinuous reception-activation period timer);

or,

b) indicating whether to detect the PDCCH during the activation period of the next at least one DRX cycle;

or

c) Indicate the time position that satisfies the constraint relationship between the drx-ShortCycle and the drx-StartOffset parameter, and/or the time position that satisfies the constraint relationship between the drx-LongCycle and the drx-StartOffset parameter in at least one next DRX cycle, and/or , the time position that satisfies the constraint of the drx-SlotOffset parameter, starts the drx-onDurationTimer;

or,

d) Instruct to detect the PDCCH within the active period of the next at least one DRX cycle. Examples are given below.

For example, the first information indicates the on duration (activation period) of the next DRX cycle, and the terminal does not need to wake up to receive the PDCCH, that is, there will be no PDCCH scheduling in the on duration of the next DRX cycle, and the terminal can continue to keep the inactivity (inactive) state to achieve the effect of energy saving.

For example, when using Short DRX Cycle, satisfy [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle), or, when using Long DRXCycle, satisfy [(SFN ×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset, the start position of the subframe starts offset from the time position indicated by drx-SlotOffset and starts drx-onDurationTimer.

Through the indication signaling, it is possible to indicate whether to start the drx-onDurationTimer at the next times when the drx-onDurationTimer should be started.

Alternatively, it indicates whether to detect the PDCCH at the next activation time.

The activation time includes the activation time stated in 38.321: When DRX is configured, the activation time includes the following:

-drx-onDurationTimer or drx-InactivityTimer or drx-RetransmissionTimerDL or drx-RetransmissionTimerUL or ra-ContentionResolutionTimer (random access procedure contention resolution timer) during operation;

or

- An SR (scheduling) request was sent on the PUCCH, but no response has been received (in the pending stage);

or

- A random access response has been successfully received. The random access sequence corresponding to the random access response is not selected by the MAC (medium access control) entity from the contention-based random access sequence, but the corresponding random access sequence has not been received. The PDCCH in the C-RNTI of the MAC entity indicates the transmission of new data.

2. The second information is used to indicate the configuration of DRX parameters of the at least one DRX cycle

In this embodiment of the present invention, optionally, the DRX parameter includes at least one of the following: drx-onDurationTimer (discontinuous reception-active period timer), drx-InactivityTimer (discontinuous reception-inactive period timer), drx -HARQ-RTT-TimerDL (Discontinuous Reception - Hybrid Automatic Repeat Request - Round Trip Time Timer), drx-HARQ-RTT-TimerUL (Discontinuous Reception - Hybrid Automatic Repeat Request - Round Trip Time Timer), drx-RetransmissionTimerDL (Discontinuous Reception-Retransmission Timer), drx-RetransmissionTimerUL (Discontinuous Reception-Retransmission Timer), drx-LongCycleStartOffset (Discontinuous Reception-Long Cycle Start Offset), shortDRX (Short Cycle Discontinuous Reception) and drx-SlotOffset (discontinuous reception-slot offset).

The configuration of DRX parameters is as follows:

In this embodiment of the present invention, the configuration of DRX parameters may be indicated in the following manner:

a) The configuration of multiple sets of DRX parameters is sent through high-layer signaling, and the configuration of at least part of the DRX parameters in each set is different from the configuration of the DRX parameters of other sets; wherein, the second information is used to indicate the multiple sets of DRX parameters set of configurations.

b) Sending a set of DRX parameter configurations through high layer signaling; wherein the second information includes a scaling factor, and the DRX parameters applied to the at least one DRX cycle are configured by the high layer signaling for DRX The configuration of parameters and the scaling factor are determined.

In this embodiment of the present invention, the scaling factor may be 1/8, 1/4, 1/2, 1, 2, 4, 8 and other values.

For the value of the timer (one or more of the above-mentioned timers) in the configuration of the DRX parameter, the scaling factor can be multiplied by the value of the timer configured by the higher layer, and the obtained result can be added to the value of the timer in the value range of the timer. Comparing optional values to find the closest timer value, or the largest optional value smaller than the multiplication result, or the smallest optional value larger than the multiplication result, as applied to the at least one The value of the timer of the DRX cycle. In addition, if the multiplication result is a decimal, it can be rounded first.

For the scaling factors of the long DRX cycle and the short DRX cycle, the cycle and offset values of the long DRX cycle are defined at the same time, and the cycle and offset values can be multiplied by the scaling factor and then rounded. For the value of the Short DRX cycle, the ratio between the high-level configuration and the long DRX cycle can be k. For example, the cycle of the long DRX is k times that of the short DRX cycle, then the scaling factor can be directly multiplied and rounded. The corresponding value of the long DRX cycle is divided by k to obtain the corresponding value of the short DRX cycle.

3. The third information is used to indicate the detection state of the PDCCH

The complexity of PDCCH detection comes from the fact that there are many PDCCH configurations that the terminal needs to blindly detect at the same time. For example, there are many search space types, search space sets, and DCI formats (downlink control information formats). There are many candidates.

Therefore, various types of configuration information can be combined and indicated to the terminal through the indication signaling. The terminal will omit unnecessary detection according to the indication signaling, and only perform blind detection of part of the PDCCH, thereby reducing the detection of the terminal. the complexity. The above configuration information includes at least one of the following: type of search space, set of search space, RNTI of search space, DCI format, length of DCI, and candidate ratio of PDCCH.

The combined design collection is performed through different state values of some or all of the above configuration information. Take the PDCCH detection of the user in the connected state as an example. For the terminal in the connected state, the system information can only be read at a fixed time, and the change of the system information is indicated by paging (paging). Consider the detection of system messages. PDCCH detection for paging (transmission of control information scrambled by P-RNTI), random access response (random access response, transmission of control information scrambled by RA-RNTI or TC-RNTI) and other SFI (slotformat indicator, Time slot format indication), power control command, interrupted transmission indication (detection of type3 common control information such as interrupted transmission indicator).

The state of the search space type can be divided into: common search space, UE specific search space, and both the common search space and the UE specific search space need to be detected.

The status of the DCI format can be divided into: the common search space includes DCI format 0_0, 1_0, 2_0, 2_1, 2_2, 2_3. The UE specific search space has 0_1, 1_1, 0_0, 1_0.

These formats can be further grouped according to the DCI size of the format, and a status indication is made for the same grouping. For example, the DCI formats 0_0, 1_0, 2_2, 2_3 of the public search space can be merged into the same state due to the same DCI size. If the location, that is, the monitoring occasion (monitoring occasion) occurs in the same time slot, the terminal may need to blindly detect multiple DCI formats at the same time.

The PDCCH candidate ratio can be divided into 1/4, 1/2, and 1 of the candidates configured in the search space (search space); that is, only the first 1/4 candidates, 1/2 candidates, and all candidates need to be detected during detection. . As for the value of the ratio, there can be other settings. In order to ensure that the final number of candidates is an integer value, it can also be rounded up or rounded down.

If you consider the search space set (search space set), it can be 1/4, 1/2, 1 of all sets; or the configured search space set can be divided into different groups according to ID, for example, group 1 corresponds to search spaceID 0 to 1, group 2 corresponds to IDs 2 to 3, group 3 corresponds to IDs 4 to 5, and successive group 5 corresponds to 8 to 9. The number of configured groups and the corresponding ID conditions can be configured by a high layer.

RNTI distinction, for example, different RNTI scrambling will be distinguished for the same type of search space. But usually the same DCI size, the blind detection complexity brought by different formats is not large, therefore, the energy saving effect of RNTI distinction is limited.

Part or all of the above configuration information are combined to form different indication states of the control information.

a) In some embodiments of the present invention, the third information includes: state indication information, the state indication information corresponds to a detection state of the PDCCH, and each of the detection states includes n types of configuration information values Combination, n is a positive integer greater than or equal to 1, and the n kinds of configuration information are selected from at least one of the following configuration information: type of search space, set of search space, RNTI of search space, DCI format, length of DCI and The candidate ratio of PDCCH.

Examples are given below.

Table 2 3-bit table indication

Taking the status indication information as 110 as an example, it indicates that the current user only needs to detect the UE specific search space. If the current time slot corresponds to the paging occasion (paging occasion), since the paging control information belongs to the public control information, it means that the current user does not need to detect the UE specific search space. There will be paging control information sent, and users do not need to detect paging to obtain system message updates. The detected DCI format includes both fall back DCI, that is, DCI format 0_0, 1_0, and DCI format 0_1, 1_1. This state is applicable when the user configures multiple UE-specific search spaces, because a certain The search space can only monitor DCI format 0_0,1_0 or DCI format 0_1,1_1. Simultaneous monitor DCI format 0_0,1_0 and DCIformat0_1,1_1 are only required in the case of multiple search spaces.

For the status indication information of 101, since the indication only requires monitor DCI format 0_1, 1_1, for those search spaces configured to detect DCI format 0_0, 1_0, the user does not need to perform detection.

For the status indication information to be 000, it means that the current UE does not need to perform control channel detection.

The above table design is only an example here. How many kinds of configuration information are combined in the current state indication information, and which kinds of configuration information are combined, and the state division of each configuration information can be configured by a high layer. That is, the base station can send the correspondence between the status indication information and the detection status of the PDCCH through high-layer signaling, wherein each of the status indication information corresponds to one of the detection statuses.

b) In some embodiments of the present invention, the third information includes: x bits, where the x bits are used to indicate a combination of values of y types of configuration information, wherein each type of the configuration information corresponds to the At least 1 bit of x bits, wherein the y types of configuration information are selected from at least one of the following configuration information: type of search space, RNTI of search space, DCI format, length of DCI, candidate ratio of PDCCH and search space gather.

For example, the third information includes: x bits, which are used to indicate a combination of values of two kinds of configuration information, including the search space set and the candidate ratio. Assuming that the search space set is divided into 5 groups, 5 bits are used, and each bit corresponds to a group to indicate which search space sets need to be detected. At the same time, the ratio of candidates is also indicated. Assuming that there are 4 candidate ratios, there are two ways. One is to have 2 bits for each search space set (in this case, x is equal to 15). The other is to make a common 2-bit indication for all search space sets (in this case, x is equal to 7).

The indication information itself may be an individual indication for each UE, or a common indication.

For example, the combination indicated by the current indication information includes only one type, that is, the ratio of PDCCH candidates, and there are 3 ratio states, so 2-bit indication information is required.

When a common indication is used, each information only contains 2 bits, and the UE that detects this information follows the same control channel detection information;

When the UE alone indicates, there are two ways. One is that each UE detects its own indication information. The other is that multiple UEs are multiplexed in the same indication information, and each UE corresponds to different 2 bits in the indication information. The way of indicating other first, second and fourth information is similar.

4. The fourth information is used to indicate the detection state of the next at least one paging occasion.

The indication information here can also be used to indicate the paging status of the RRC IDLE state. Similar to the role of WUS, it indicates whether there is a valid paging message sent at the paging time of the terminal. If no valid paging message is sent, the terminal does not need to detect The control channel for scheduling paging messages can continue to maintain a low power consumption mode to achieve the effect of energy saving. The difference is that the transmission resources are different from WUS. WUS occupies the entire bandwidth and transmits one or more subframes. The transmission resources of the indication information here are determined by the time domain and/or frequency domain resources for transmitting the synchronization signal/physical broadcast channel block SSB.

3. Indication form of indication signaling

In this embodiment of the present invention, the indication signaling may be indicated in the following manner:

a) The indication signaling may be common indication signaling, that is, the indication content of the signaling is the same for all UEs;

b) The indication signaling includes indication signaling of m terminals, where m is a positive integer greater than or equal to 1;

In this mode, different UEs occupy different bits in the signaling in the indication information, and in this indication mode, the control information may be different for different UEs.

c) The indication signaling is terminal-specific signaling.

The indication information may indicate that the UE needs to detect control information in one or more time slots. Wake-up or configuration information for one or more DRX cycles may also be indicated.
