Detailed Description

In order 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, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: terminal side devices 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 the specific type of the terminal is not limited in the embodiments of the present invention. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NRNB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or an Access Point (AP); the base station may also be a network node that is composed of a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be noted that, in the embodiment of the present invention, the specific type of the network side device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a method for transmitting an energy saving signal according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. the network side equipment determines the transmission resource of the energy-saving signal;

202. and the network side equipment transmits the energy-saving signal through the transmission resource, wherein the energy-saving signal comprises a plurality of sequences.

In an embodiment of the present invention, the power saving signal may be a signal for waking up, or activating (or triggering) a detection control channel, or enabling the terminal to start selling detection related to decoding of the control channel. For example: the energy saving Signal may be a Wake Up Signal (WUS), but is not limited thereto, and for example: the energy-saving signal may also be another signal defined in the protocol, or another signal pre-agreed by the network side device and the terminal.

The transmission resource of the energy-saving signal may refer to a transmission resource for transmitting the energy-saving signal. The determining of the transmission resource of the energy saving signal may be performed according to a terminal or a terminal group, for example: the transmission resource of the power saving signal of each terminal may be determined according to the terminal, or the transmission resource of the power saving signal of the terminal in the terminal group may be determined according to the terminal group.

In addition, in the embodiment of the present invention, the same sequence indication may indicate one or more functions, for example: a certain sequence may indicate one or more of Wake up area identification (Wake up area ID), Cell identification (Cell ID), terminal identification, carrier information, system information update, distance information, end of data, and the like. The terminal receives the energy-saving signal and then analyzes the indication of the functions to execute corresponding actions. For example: wake up, detect control channels, detect data channels, obtain system information, enter a sleep state, and so on. In this way, a plurality of functions can be indicated by the plurality of sequences, and thus the communication performance of the communication system can be improved.

In addition, in the embodiment of the present invention, the power saving signal may be applied to a Connected (RRC _ Connected) terminal, or a non-Connected terminal, such as an IDLE (RRC _ IDLE) terminal or a non-activated (RRC _ Inactive) terminal. In some embodiments, the same energy-saving signal can be applied to both the connected-state terminal and the unconnected-state terminal, so that the energy-saving signal has a nested characteristic, and transmission resources are saved.

It should be noted that, in the embodiment of the present invention, the Control Channel may be a Physical Downlink Control Channel (PDCCH), but is not limited to this, and in the embodiment of the present invention, the Control Channel may refer to an existing Control Channel and various possible future Control channels, for example: an Enhanced Physical Downlink Control Channel (ePDCCH) or a machine type communication Physical Downlink Control Channel (MPDCCH) and so on. In addition, the embodiment of the invention can support an authorized frequency band and also can support an unlicensed frequency band. The embodiment of the invention can be suitable for NR technology and other communication systems, such as LTE.

Optionally, in this embodiment of the present invention, the energy saving signal includes three or more sequences. Thus, the energy-saving signal can realize more functions through three or more sequences, thereby further improving the communication performance of the communication system. Of course, in the embodiment of the present invention, the energy saving signal may also include two sequences, which is not limited in this respect.

As an optional implementation manner, the determining, by the network side device, transmission resources of the energy saving signal includes:

The grouping of the terminals may be performed according to a terminal identification (UEID) of the terminal, for example: the terminals in the same terminal group have the same UE ID, or the UE IDs of the terminals in the same terminal group are different but satisfy a certain relationship, for example, the UE IDs of the terminals in the same terminal group in the group have the same value after modulo a certain value. In addition, the ue id in the embodiment of the present invention may be a user identifier, and is not limited to a Radio Network Temporary Identity (RNTI), for example: the ID information of the terminal in the Wake up area (Wake up area) or the paging area (paging area) may be used, or may be a function of the global unique identifier of the terminal, such as modulo operation of the global unique identifier of the terminal.

In this embodiment, the transmission resource of the energy-saving signal is determined according to the terminal group, so that the network side device can be effectively prevented from sending the wake-up signals of all the terminals on the same resource, thereby reducing the interference of the terminal in detecting the wake-up signals and reducing the difficulty in designing the wake-up signals.

Optionally, the power saving signal includes one or more signal subsets;

at least one signal subset of terminals in the same terminal group adopts the same transmission resource, and the transmission resource comprises time domain resource and frequency domain resource; or

At least one signal subset of terminals in the same terminal group adopts the same time domain resource, and at least one signal subset of different terminals in the same terminal group adopts different frequency domain resources; or alternatively

In the embodiment of the present invention, the signal subsets may be one or more symbols, and one and the same signal subset may include one or more sequences. It should be noted that, the one or more signal subsets may be referred to as one or more subsets of one energy saving signal, and may also be referred to as one or more different energy saving signals. In addition, the transmission resources for different subsets of signals may be different, for example: different subsets of signals are transmitted on different time domain resources.

The above-mentioned at least one signal subset of terminals in the same terminal group using the same transmission resource may mean that all signal subsets of terminals in the same terminal group use the same time domain resource and frequency domain resource; or, a part of signal subsets of terminals in the same terminal group use the same time domain resources and frequency domain resources, while another part of signal subsets use the same time domain resources but use different frequency domain resources, or another part of signal subsets use the same frequency domain resources but use different time domain resources. That is, multiple resource allocation schemes may be used in combination, for example, when the energy saving signal includes multiple signal subsets to be transmitted, it may be considered that each signal subset is mapped to a different resource allocation scheme.

In this embodiment, at least one signal subset of terminals in the same terminal group uses the same time domain resource and frequency domain resource, so that transmission resources for transmitting energy-saving signals in the communication system can be saved.

The above-mentioned at least one signal subset of terminals in the same terminal group using different transmission resources may be that all or part of signal subsets of terminals in the same terminal group use different time domain resources and frequency domain resources.

In this embodiment, because at least one signal subset of terminals in the same terminal group uses different transmission resources, flexible configuration can be performed according to the requirements of different terminals, thereby improving the flexibility of energy-saving signal transmission and increasing the communication performance of the communication system.

The above-mentioned at least one signal subset of terminals in the same terminal group uses the same time domain resource, and at least one signal subset of different terminals in the same terminal group uses different frequency domain resources, which may mean that all signal subsets in the same terminal group use the same time domain resource, and different signal subsets use different frequency domain resources, or may mean that some signal subsets in the same terminal group use the same time domain resource, and different signal subsets in the same signal subset use different frequency domain resources. Therefore, different energy-saving signals can be sent to a plurality of terminals in the same time domain resource, and the time domain resource of the terminals can be saved.

The above-mentioned at least one signal subset of terminals in the same terminal group uses the same frequency domain resource, and at least one signal subset of different terminals in the same terminal group uses different time domain resources, may mean that all signal subsets in the same terminal group use the same frequency domain resource, and different signal subsets use different time domain resources, or may mean that some signal subsets in the same terminal group use the same frequency domain resource, and different signal subsets in the signal subsets use different time domain resources. Therefore, different energy-saving signals can be sent to a plurality of terminals in the same frequency domain resource, and the frequency domain resource of the terminals can be saved.

It should be noted that, in the embodiment of the present invention, a unit of the time domain resource may refer to different Orthogonal Frequency Division Multiplexing (OFDM) symbols or time slots or other time domain resource units, which is not limited in this respect. The unit of the frequency domain Resource may be a Physical Resource Block (PRB), or may be a subcarrier, or may also be a frequency domain Resource unit, which is not limited.

The terminals in the terminal group have the same UE ID, or the UE IDs of the terminals in the terminal group are different but satisfy a certain relationship, for example, the UE IDs of the terminals in the same terminal group in the group have the same value after modulo a certain value.

The determining of the frequency domain resource of the energy saving signal corresponding to the terminal identifier may be that the frequency domain resource determined for the terminal is corresponding to the terminal identifier of the terminal, or that the frequency domain resource determined for the terminal group is corresponding to the terminal identifier in the terminal group.

Due to the fact that the determined frequency domain resources and the time domain resources are corresponding to the terminal identification, the frequency domain resources and the time domain resources do not need to be added with extra information when being determined, and complexity of implementation is reduced.

Optionally, the determining, by the network side device, the frequency domain resource of the energy saving signal corresponding to the terminal identifier for the terminal or the terminal group includes:

the network side equipment determines the frequency domain resource of the energy-saving signal corresponding to the terminal identifier for the terminal or the terminal group in a static or semi-static mode; and/or

The determining, by the network side device, the frequency domain resource of the energy saving signal corresponding to the terminal identifier for the terminal or the terminal group in a static or semi-static manner may include:

the network side equipment determines the frequency domain Resource of the energy-saving signal corresponding to the terminal identification for the terminal or the terminal group through Radio Resource Control (RRC) signaling semi-static; or alternatively

And the network side equipment determines the frequency domain resource of the energy-saving signal corresponding to the terminal identification for the terminal or the terminal group in a predetermined or system information indication mode.

In this embodiment, the frequency domain resource of the energy saving signal corresponding to the terminal identifier is determined for the terminal or the terminal group in a static or semi-static manner, so that the transmission resource of the dynamic signaling can be reduced to save the transmission resource.

As an alternative embodiment, the power saving signal includes a plurality of signal subsets, wherein a partial signal subset precedes another partial signal subset.

Wherein, the time domain resources of the another part of signal subsets may be dynamically configured, for example: the energy-saving signal comprises a signal subset 1 and a signal subset 2, wherein the signal subset 1 precedes the signal subset 2, and the time domain resource of the signal subset 2 is related to the transmission starting point of the data reality, for example: the time domain resource of the signal subset 2 is 0 related to the interval of the transmission start point of the data, or the interval is within a preset range, and so on. And the time domain resources of the partial signal subsets may be statically or semi-statically configured.

In this embodiment, the present invention is not limited to be applied to the DRX scenario, and for example: in a non-DRX scenario, the power saving signal may also include a plurality of signal subsets, wherein a subset of signals precedes another subset of signals.

Wherein, the time domain resource of the partial signal subset for the DRX scenario may be according to the terminal identity and the DRX cycle. When the power saving signal includes a plurality of signal subsets, the determining, by the network side device, the time domain resource of the power saving signal of the terminal according to the terminal identifier and the DRX cycle may include:

and the network side equipment determines that the time domain resources of a partial signal subset of the energy-saving signal of the terminal are before or in the DRX period according to the terminal identification, wherein the other partial signal subset is dynamically transmitted on the OFDM symbol.

In this embodiment, it may be achieved that the time domain resource of the partial signal subset is determined before the DRX cycle or within the DRX cycle, and another partial signal subset is dynamically transmitted, so that the flexibility of energy saving signal transmission may be improved, and the function of the terminal may also be reduced. For example: the signal subsets can be dynamically transmitted by OFDM symbols in front of the PDCCH, so that the terminal reduces the time of blind detection of the PDCCH by the terminal, and the purpose of energy saving is achieved.

Certainly, in this embodiment of the present invention, the network side device may determine, according to the terminal identifier and the DRX cycle, the time domain resource of the energy saving signal of the terminal, and according to the terminal identifier and the DRX cycle, determine that the time domain resources of all signal subsets of the energy saving signal of the terminal are all before the DRX cycle or in the DRX cycle, which is not limited to this, for example: for non-DRX scenarios, time domain resources corresponding to the terminal identity may also be determined.

In addition, in the embodiment of the present invention, the determining, according to the terminal identifier, the time domain resource of the energy saving signal of the terminal may be determined according to a predetermined algorithm of the terminal identifier, or according to a semi-static configuration of the terminal identifier, which is not limited to this. In addition, some of the parameters in the above algorithm may be semi-statically configured.

In this way, the time domain resources of the partial signal subsets may be configured by a predetermined algorithm and/or semi-statically. For example: the semi-statically configured parameters such as DRX cycle may be included in the above algorithm.

The algorithm may be pre-agreed between the network side device and the terminal, or pre-defined in a protocol, so that the time domain resource is determined by the pre-agreed algorithm, thereby reducing the transmission overhead before the network side device and the terminal, and in addition, the time domain resource is determined by the algorithm, thereby enabling the time domain resource allocation to be more flexible

For example: if the time domain resources of the partial signal subset are determined by the algorithm, the position of the time domain resources of the partial signal subset is a function of the terminal identifier and the DRX cycle; and/or

The function may be pre-agreed between the network side device and the terminal, or pre-defined in a protocol, and specific contents of the function are not limited, for example: the function may include operations such as addition, subtraction, multiplication, division, or modulo.

The semi-static configuration is not limited to the RRC signaling dedicated to the terminal, and may be other high layer signaling or system information indication, and the like.

As an optional implementation manner, for the unlicensed frequency band, the frequency domain resources of the energy-saving signals of one or more terminals are in an interlace (interlace) structure occupying a full bandwidth; and/or

The unlicensed frequency band may include an unlicensed frequency band, and may also refer to an unlicensed frequency band outside the unlicensed frequency band. The above-mentioned interlace structure occupying the full bandwidth may be an interlace structure occupying the entire transmission bandwidth of the terminal.

Optionally, the interlace structure includes multiple resource sets, where a resource with the same index in the multiple resource sets serves as an interlace;

that is, the interlace structure may include a plurality of interlaces, wherein each interlace includes resources of the same index in different resource sets, respectively.

For example: with resource aggregation as a group (group) of multiple consecutive PRBs, as shown in fig. 3, the full bandwidth is first divided into multiple groups by one group every 10 consecutive PRBs, assuming that a total of N groups is obtained; each of the N groups takes one PRB to form an interlace, that is, a PRB set with the same index (index) in the N groups in fig. 3, where the index is 0. Of course, in the embodiment of the present invention, the resource set is not limited to a group formed by a plurality of consecutive PRBs, for example: the set of resources may be a set of subcarriers. That is, the granularity of the frequency domain resource may be PRB or an integer multiple of the number of subcarriers, but is not a multiple of PRB.

In addition, when the network side device needs to allocate all terminals of the energy saving signal or the energy saving signal of one terminal occupies all interlaces in the interlace structure, the energy saving signal includes an orthogonal sequence.

For the authorized frequency band, the frequency domain resource of the energy saving signal of one or more terminals may be an interlace structure occupying part or all of the bandwidth, where the interlace structure may occupy part or all of the transmission bandwidth when in the authorized frequency band, the network side device sends the energy saving signal on an interlace allocated to a certain terminal, and the number of interlaces allocated to the terminal by the network side device and the interlace index thereof are semi-statically configured or agreed in advance. As shown in fig. 3, different terminals use different interlaces, and preferably, when the number of users is large, different terminals may allocate the same interlaces, which is the case where the energy saving signals of the terminals in the terminal group use the same frequency domain resource as described in the foregoing embodiment.

In this embodiment, the frequency domain basic unit for energy-saving signal transmission can be interlace, so that frequency domain resources can be fully utilized to improve resource utilization rate. And the interlace structure is adopted, so that only the interlace index needs to be indicated when the resources are allocated, and the signaling overhead is saved.

As an alternative embodiment, the power saving signal comprises a subset of m signals, wherein the subset of signals i comprises n _i A sequence of, wherein m>＝1，0＝<n _i <N, i is 1,2,. m, and n ₁ +n ₂ +,…+n _m N is the number of sequences included in the power saving signal.

In this embodiment, it can be realized that the power saving signal includes one or more signal subsets, and the number of sequences included in different signal subsets may be the same or different, for example: some subset of signals may include 0 sequences, while other subset of signals may include one or more sequences. Therefore, the flexibility of the energy-saving signal can be improved to adapt to different scenes, services or the requirements of terminals.

Pseudo-Noise (PN) sequences, ZC sequences, orthogonal sequences, Costa sequences, Kasumi sequences, Primary Synchronization Signal (PSS) sequences, Secondary Synchronization Signal (SSS) sequences, functionally equivalent Synchronization sequences, and sequence combinations.

The Costa sequence may be a Costa sequence defined in a protocol, or may be a time domain sequence determined by the following formula:

wherein s is _CS (n) represents the Costa sequence described above, and the length of the Costas sequence is LM. Where vl is a sequence of integers, L and M are constants, n is a constant, p (n) is defined as follows,

for example: generating a Costas sequence with length of 256, L ═ M ═ 16, ν can be set _l The following sequence was used:

{ν _l }＝{5 2 8 9 12 4 14 10 15 13 7 6 3 11 1 5}

in addition, a 256-point frequency domain sequence can be obtained by a 256-point discrete Fourier transform (FFT).

It should be noted that the above formula is only an example of the Costa sequence, and is not limited thereto, for example: but also Costa sequences generated by other formulas.

And the above Kasami sequence may be generated as follows:

a selected period of 2 ⁿ 1(n is an even number) m sequences a, every 2 pairs of sequences a ^n/2 +1 samples to get a length of 2 ^n/2 -1. It can be verified that this sequence remains m-sequence, and this sequence is repeated 2 ^n/2 +1 passes to obtain a sequence a' with the same length as the sequence a. And adding the a sequence and the a' sequence bit by bit modulo 2 to obtain a Kasami sequence. In addition, when one of the sequence phases is changed (shifted backward or forward), a new Kasami sequence is obtained.

It should be noted that the above description is only an example, and the m-sequence a is not necessarily periodic, and the length thereof is not necessarily the sameBut is 2 ⁿ -1(n is an even number), etc.

The sequence included in the energy-saving signal can be flexibly configured according to actual requirements. In this embodiment, the energy-saving signal can include a plurality of sequences, so that the energy-saving signal has a stronger function, and the communication performance of the communication system is further improved.

Optionally, the power saving signal is used to indicate at least one of:

wake-up area identification (Wakeup area ID), Cell identification (Cell ID), terminal identification (UEID), carrier information, system information update, distance information and data end, wherein the distance information represents the distance between the energy-saving signal and the control channel.

Since the power saving signal may indicate at least one of the above items, the function of the power saving signal may be improved to further improve the communication performance of the communication system.

In this embodiment, one sequence may indicate one or more of the plurality of items, one sequence may indicate one of the plurality of items, or a plurality of sequences may jointly indicate one item, and the like, which is not limited thereto.

For example: the same sequence in the energy-saving signal indicates one or more of the wake-up area identifier, the cell identifier, the terminal identifier, the carrier information, the system information update, the distance information and the data end. This saves the overhead of power saving signals since one sequence may indicate one or more terms.

Another example is: the energy-saving signal indicates a wake-up area identifier through at least one sequence; and/or

The power save signal indicates the end of the data by at least one sequence.

This allows different functions to be indicated by different sequences to increase the flexibility of the power saving signal.

In this embodiment, it may be implemented that multiple sequences occupy the same OFDM symbol, or multiple sequences occupy multiple OFDM symbols, for example: different sequences occupy different OFDM symbols or some sequences occupy the same OFDM symbol and some occupy different OFDM symbols to increase the flexibility of the power saving signal.

The following is illustrated by taking the power saving signal as the wake-up signal according to different indications:

for Wake up area ID indication, the Wake up signal carries multiple information fields, each information field carries one subsequence, and the Wake up area ID maps to one of the subsequences, for example:

wherein, the multi-level sequence of the Wake-up signal occupies one or more OFDM symbols in the time domain, sequence 1 represents the mapping Wake up area ID information, preferably sequence 1 is a function of the Wake up area ID, e.g. the Wake up area ID is the root index of the ZC sequence. The terminal firstly detects the sequence 1 at the mapped WUS sending position, if the Wake up area ID of the sequence identification is found to be the Wake up area identification of the terminal, the terminal can continue to detect the latter sequence, otherwise, the terminal stops detecting the latter multi-stage sequence and continues to enter the sleep state, thus being very beneficial to saving the power consumption of the terminal.

For Cell ID indication, the wake-up signal carries multiple information fields, each information field carrying one subsequence, to which the Cell ID maps 1-2 subsequences, for example:

the multi-stage sequences of the wake-up signal respectively occupy one or more OFDM symbols in a time domain, PSS/SSS can be reused by the

sequences

2 and 3 for time-frequency coarse synchronization operation, Cell ID can be identified after the terminal successfully detects the PSS/SSS of the synchronization sequence, and PSS/SSS design sequences can be reused by the

better sequences

2 and 3. After the terminal resolves the Cell ID, coarse synchronization can be completed, and the Cell ID can be used to assist subsequent decoding of a Physical Broadcast Channel (PBCH), for example, the PSS/SSS in the SSB can be directly detected or the PBCH can be directly detected by removing the PSS/SSS detection step directly according to the sequence ID and the previous synchronization information, thereby realizing fast Cell search for the RRC-connected mode terminal.

For the UE ID indication, the UE ID maps one or more subsequences of the wake-up signal, such as:

sequence 4 may be used for ue id indication, for example, a PN sequence may be generated as sequence 4 using ue id as initial information, and the sequence may occupy one or more OFDM symbols in time domain. And after detecting that the former multi-stage sequence belongs to the sequence of the UE, the UE starts to detect the sequence of the UE ID mapping, for example, through the peak value judgment of sliding correlation detection, if the terminal finds that the UE identified by the sequence is the UE, the subsequent sequence is continuously detected, and otherwise, the WUS detection is stopped, and the UE continues to enter a sleep state.

For carrier information indication, the carrier information maps to a subsequence of the wake-up signal, such as:

for example, the sequence 5 may be used for carrier information indication, for example, indicating that the base station supports 4 carriers for the terminal, the base station uses 4 bits [ b0b1b2b3] as an index indication of the activated carrier, and may use bit mapping (bit mapping) to set the bit of the activated carrier mapping to 1, set the bit of the inactivated carrier mapping to 0, and then use the decimal value of the bit mapping vector mapping as the input of the PN sequence, or the root index of the ZC sequence to obtain the sequence of carrier information mapping. The terminal can prepare for subsequent power ramp on the carrier after detecting the sequence mapped by the carrier information, and the method effectively avoids the need of detecting WUS in a plurality of radio frequency channels and continues to enter a sleep state on the carrier which is not activated, thereby obviously reducing the power consumption of the terminal.

For the system information update indication, the system information update indication maps to a subsequence of the wake-up signal, such as:

if sequence 6 can be used for system information update indication, the sequence only needs to distinguish whether the system information needs to be updated or not, so only two cases (cases) are mapped, for example, two orthogonal sequences can be constructed, where sequence 0 indicates that the system information is not updated, and sequence 1 indicates that the system information needs to be updated. The terminal can obtain the indication of the system information only by detecting the mapping sequence at the mapping position. If the wake-up signal sequence carries the system information updating mark, the terminal will detect new information at the later system information updating time. If the wake-up signal has no system Information update flag, the terminal considers that Downlink data arrives, and the terminal in RRC _ IDLE and RRC _ Inactive mode will detect Downlink Control Information (DCI) of paging (page), and then detect PDSCH for data reception.

Distance information for wake-up signal and mapped PDCCH

As shown in fig. 4, the WUS may be divided into a plurality of subsets, such as WUS subset 1 for indicating that the terminal is about to have data to arrive in the present DRX cycle, and the terminal starts to start power ramp-up after correctly identifying WUS subset 1, and prepares for normal receiving and measuring operations. However, the terminal may have a longer distance from the position of the WUS subset 1 to the data arrival, in order to avoid the terminal blindly detecting the PDCCH after waking up, a sequence is introduced to indicate the distance from the WUS subset 1 to the PDSCH, optionally the WUS subset 2 is introduced before the PDCCH or the PDSCH, and the distance indicated by the sequence may also be the distance between the WUS subset 1 and the subset 2. The distance may be expressed in terms of the number of OFDM symbols, which need only be input as a sequence that is a function of the distance. The distance may be accurate to OFDM symbols but also to an estimate, e.g. to a subframe or slot. The terminal finds that the WUS subset 1 starts to start power climbing, necessary cell searching and wireless channel measuring processes are carried out, but PDCCH blind detection is not carried out, and the PDCCH blind detection operation is not started until the WUS subset 2 arrives and detection is successful. Since the complexity of the WUS subset 2 indicating the arrival of the PDCCH is low, the terminal can start detecting the WUS subset 2 after the WUS subset 1 receives the PDCCH, and the distance indication between the WUS and the PDCCH is used as further verification, or both signals can be solved to perform blind detection on the PDCCH, and of course, only one indication information can be reserved, for example, only the WUS subset 2, or only the distance indication information between the WUS and the PDCCH.

For the end of data indication, the power saving signal is as follows:

after the terminal detects and successfully decodes the data belonging to the subset, the terminal does not know whether the base station continues to transmit the data to the terminal, so that the terminal cannot enter a sleep state after being activated by the WUS even if the data is finished. In a specific method, a sequence may be designed, such as similar to indicating whether system information is changed, for indicating whether data is over, as shown in fig. 5. The WUS subset (set)1 is used for indicating data arrival, the terminal starts power ramp-up, the WUS set2 is used for activating PDCCH detection, the WUS set3 is used for detecting whether data is finished, and the terminal enters a sleep state if the WUS set3 is successfully detected. For ease of detection in fig. 5, WUS set3 is placed at the last symbol of DRX on, but does not exclude its more power-saving benefit, as WUS set3 is located after the PDSCH at the agreed OFDM symbol number from the PDSCH.

As an alternative implementation, the power saving signal includes a plurality of sequences, a part of the sequences is used for connected terminals, and the whole sequences are used for unconnected terminals.

The operation state of the terminal in the NR may include: RRC _ IDLE, RRC _ Inactive, and RRC _ Connected, and the terminal has two operating states RRC _ IDLE and RRC _ Connected in LTE. A terminal in RRC _ IDLE mode may need more time to wake up after being woken up by the WUS than a terminal in RRC _ Connected, and may need to perform more operations than RRC _ IDLE, and the WUS may support more functions. For example: as shown in the following table, the power saving signals in different states preferably have a nested relationship, where sequences 1 to n 'are used in RRC _ Connected mode, and 1 to n are used in RRC _ IDLE mode, and if the terminal is in RRC _ Connected mode, only sequences 1 to n' need to be detected, thereby reducing the detection complexity.

In this embodiment, since part of the sequence is used for the connected terminal and the whole sequence is used for the unconnected terminal, different energy-saving signals do not need to be sent to the network side devices of the terminals in different states, thereby reducing the transmission overhead.

It should be noted that, in the embodiment of the present invention, the various optional implementation manners provided above may be implemented independently, or may be implemented in combination with each other, which is not limited herein.

In the embodiment of the invention, network side equipment determines the transmission resource of the energy-saving signal; and the network side equipment transmits the energy-saving signal through the transmission resource, wherein the energy-saving signal comprises a plurality of sequences. Thereby, the transmission of the power saving signal including a plurality of sequences can be realized, and the communication performance of the communication system can be improved.

The energy saving signal is illustrated by a number of embodiments below:

example 1

In order to effectively avoid the base station from sending the WUSs of all users on the same resource, thereby reducing the interference of UE detecting the wake-up signal and reducing the difficulty of wake-up signal design, the following design scheme can be adopted.

Firstly, the network divides the UE needing to monitor the WUS into a plurality of groups according to the UE ID information, and each group of UE sends a wake-up signal on the same resource. The UE ID is only a user identity, and is not limited to RNTI, for example, ID information of the UE in Wake up area/paging area may be also a function of the global unique identity of the UE, such as a modulo operation of the global unique identity of the UE.

And the network divides the UE needing to monitor the WUS into a plurality of groups according to the UEID information, and each group of UE sends the wake-up signal on the same frequency domain resource and different time domain resources. The different time domain resources may refer to different OFDM symbols or time slots, for example.

And thirdly, the network divides the UE needing to monitor the WUS into a plurality of groups according to the UE ID information, and each group of UE sends the wake-up signal on the same time domain resource and different frequency domain resources, for example, the wake-up signal can be sent on different PRB resources calculated according to the UE ID.

And fourthly, the network divides the UE needing to monitor the WUS into a plurality of groups according to the ID information of the UE, and the UE in the groups respectively sends the wake-up signals on different time domain resources. The number of users in the group is 1, which is a special case of the above scheme, and when the number of users in the group is greater than 1, the mode one to the mode three and the mode four has smaller resource overhead. The above four schemes may be combined if necessary, for example, when the wake-up signal includes a plurality of subsets to be transmitted, different resource allocation schemes for each WUS subset may be considered.

Example 2

In all of the three schemes described in embodiment 1, resources for transmitting a wake-up signal need to be configured, and unlike a transmission resource for transmitting a paging signal (paging signal) which is indicated by a PDCCH, a base station needs to determine time-frequency resources for WUS transmission in advance before blind detection of the PDCCH.

The method for the configuration of the WUS frequency domain transmission resource comprises the following steps:

the base station configures the WUS frequency domain transmission resources for the UE or the UE group in a static or semi-static mode, and the frequency domain resources are mapped with the UE ID. The UE group is determined according to a determined rule, for example, the UEs in the group have the same UE id identifier, or the UE ids in the group are different but satisfy a certain relationship, for example, the UE ids in the group have the same value after being modulo a certain value.

Optionally, the base station may also configure resource information sent by the WUS related to the UE ID or the UE group in a semi-static manner through RRC signaling;

optionally, the base station indicates, to the UE, resource information sent by the WUS as a resource configuration supplementary method according to a predetermined or system information indication manner, which cannot be excluded, for example, the WUS is divided into a plurality of subsets, and a certain subset sending resource is configured by the method; the aforementioned transmission resource information generally refers to time-frequency resources, and sometimes includes Beam-related information, such as Beam ID.

For an example of the unlicensed band, if each WUS occupies a part of the transmission Bandwidth, it may cause that the wake-up signal may not satisfy the rule (regulation) of occupying the Channel Bandwidth (OCB), so it may be preferable to adopt an interlace structure occupying the full Bandwidth for the WUS, as shown in fig. 3. In fig. 3 first the full bandwidth is divided into multiple groups with one group per 10 consecutive PRBs, assuming a total of N groups results; in the foregoing N groups, each group takes one PRB to form an interlace (i.e. the PRB set with the same index in the N groups in fig. 3, for example, the index is 0). The frequency domain basic unit for WUS transmission is interlace. The interlace is only an example, and in each group, the granularity of the frequency domain resource allocated to each UE may be PRB, or may be an integer multiple of the number of subcarriers, but is not a multiple of PRB. The above-mentioned interlace structure is full bandwidth in the unlicensed band, and the interlace may occupy part or all of the transmission bandwidth in the licensed band. The base station sends the WUS on the interlaces allocated to a certain UE, and the number of the interlaces allocated to the UE by the base station and the interlace index thereof are semi-statically configured or agreed in advance. In the example shown in fig. 3, different UEs use different interlaces, and preferably, when the number of users is large, different UEs can allocate the same interlaces, which corresponds to the case where the users in the group occupy the same resource in embodiment 1. The invention does not of course exclude the special case that one UE occupies all interlaces, in which case in practice each UE occupies the full bandwidth, and the WUS signal is an orthogonal sequence.

The method for configuring the WUS time domain transmission resource comprises the following steps:

the base station determines the possible sending period of the UE specific wake-up signal according to the UE ID and the DRX period, and sends the wake-up signal in the WUS sending period before data transmission. The WUS may be made up of multiple subsets, with the base station needing to send some subsets of the wake-up signal before each DRX cycle or at certain locations within DRX, based on the UE ID information, dynamically sending other parts of the WUS on some OFDM symbols, as shown in fig. 4. The subset 1 of WUS is sent in a subframe M, and a base station and a terminal which send better positions make the base station and the terminal transparent to the positions through an agreed algorithm or semi-static configuration of the base station, when the algorithm is adopted for calculation, the positions are functions of UEID and DRX period, and when the semi-static configuration is adopted, the UE is preferably informed through dedicated RRC signaling of UE; the WUS subset 2, if present, transmits after the WUS subset 1, the position of transmitting the subset is related to the real transmission starting point of the data, the position is dynamic and can not be determined before the WUS subset 1 transmits, and the position has a determined mapping relation with the subset of the transmitting WUS subset 1; fig. 4 depicts only two subsets of WUS and does not preclude the presence of WUS for still other subsets. If the terminal detects the WUS, the terminal starts a timer, the timer has a threshold value configured by the base station, and if the timer is overtime but does not detect the PDCCH belonging to the terminal, the terminal enters a sleep state again.

It should be noted that

embodiments

1 and 2 correspond to the implementation of transmission resource allocation in the embodiment shown in fig. 2, and in addition, in

embodiments

1 and 2, it may not be limited that the energy saving signal includes multiple sequences, that is, in the technical solutions corresponding to

embodiments

1 and 2, the energy saving signal may include a single sequence.

Example 3

The base station transmits a wake-up signal consisting of a multilevel sequence. The wake-up signal comprises n sequences, preferably n sequences may be divided into m, m > 1 subsets, each subset comprising 0 ═ ni < ═ n, i ═ 1,2,. m sequences form the WUS subset i, and n1+ n2+, … + nm ═ n. The WUS subset may be transmitted on mapped resources according to the methods of

embodiments

1 and 2. The n sequences can be one or more of PN sequences (such as m sequences and gold sequences), ZC sequences, orthogonal sequences, Costa sequences, Kasumi sequences and the like; the m subsets of n sequences are used to transmit the wake-up signal in order to support part or a combination of the following functions:

indicating Wakeup area ID, Cell ID, ue ID, carrier information, system information update, distance information indicating wake-up signal and mapped PDCCH, and indication of end of data.

For the energy saving signal, the sequence included therein, and the like, reference may be made to the corresponding description of the embodiment shown in fig. 2, which is not described herein again.

Example 4:

in the embodiment of the present invention, the described multi-level wake-up signal or multi-level energy saving signal may be composed of different single-level signals, and the base station may notify the single-level energy saving signals used by the terminal through signaling, such as semi-static signaling, and more specifically, through RRC signaling, that is, the number of the single-level signals in the multi-level energy saving signals is variable, so that the function of the multi-level energy saving signals is also variable, and certainly, the system overhead is also variable. For example: the multi-stage energy saving signal or the wake-up signal at most comprises Nmax single-stage energy saving signals, the base station indicates the multi-stage energy saving signal or the wake-up signal through a signaling, for example, through a bit mapping (bit mapping) method, that is, the indication information comprises Nmax binary bits, which respectively correspond to the preset identifiers of the multi-stage energy saving signal, and when the multi-stage energy saving signal is adopted, the corresponding bit is set to 1. Of course, less bits of signaling may be used, such as defining several candidates (candidates) for multilevel sequence combinations, and signaling different sequence combinations. The scheme can reduce the overhead of the multi-level wake-up signal or the multi-level energy-saving signal and provide more flexibility for the network. The notification signaling is preferably semi-static signaling as described above, but does not exclude other signaling, such as dynamic signaling.

Example 5:

in an embodiment of the present invention, the described energy saving signal is used to indicate at least one of the following:

The power saving signal is not exclusive of other signals, except that it may be a multi-level power saving signal. If a PDCCH signal is sent as a power-saving signal before the DRX cycle for waking up the UE, DCI of the PDCCH is used to indicate at least one of:

the information of the area to be woken up, the cell to be woken up, the terminal to be woken up, the carrier information to be woken up, the system information update, the location information of the data start (such as relative distance information: the distance can be the distance between the energy saving signal and the control channel, the distance between the time when the data/PDCCH really arrives in the DRX on period and the DRX start, or the absolute location information such as the distance between the data end location and the DRX on period start, or the specific identification of the wireless frame, subframe, time slot or OFDM symbol reached by the data or the specific information of the wireless frame, subframe, time slot or OFDM symbol or the specific information of the data end location such as the distance between the data end location and the DRX on period start location or the distance between the energy saving signal and the data end location).
