Description

Signal transmission method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a signal transmission method and device.

Background

Currently, in each Discontinuous Reception (DRX) cycle of an RRC (Radio Resource Control) idle state, a User Equipment (UE) transmits a wake-up signal to the UE before a Paging signal at a Paging Occasion (PO) is detected in a blind manner, and the UE wakes up at a corresponding Occasion to detect the wake-up signal. If the wake-up signal indicates that the UE blindly detects a Paging Physical Downlink Control Channel (Paging PDCCH), the UE continues to blindly detect a subsequent corresponding Paging PDCCH, otherwise, the UE does not blindly detect the Paging PDCCH.

However, in the related art, one PO supports Paging information transmission of multiple UEs, and if one UE needs to be woken up to receive a Paging, the network device sends a wake-up signal to the terminal device and wakes up all UEs supported at a corresponding PO time and blindly detects a Paging PDCCH, thereby causing unnecessary power consumption of UEs that do not need to blindly detect a Paging PDCCH.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The existing Discontinuous Reception (DRX) mode includes the following two types:

1. DRX in RRC _ IDLE (Radio Resource Control, RRC) IDLE) state

In the LTE or 5G communication system, a UE in an RRC _ IDLE state needs to detect a paging signal transmitted by a base station on a preconfigured paging opportunity, and the procedure for detecting the paging signal is as follows:

blindly detecting a Paging Physical Downlink Control Channel (Paging PDCCH) (namely, a PDCCH scrambled by a Paging-Radio Network temporary identity (P-RNTI)), and if the Paging PDCCH is not detected, ending the detection; if the Paging PDCCH is detected to exist, further detecting a Physical Downlink Shared Channel (PDSCH) indicated by the Paging PDCCH, and if the detected PDSCH is not a Paging signal of the UE, ending the detection; otherwise, determining the detected PDSCH as the paging signal of the user.

The UE in RRC _ IDLE state periodically detects the paging signal, but the probability of receiving the paging signal belonging to the UE is relatively low, and the PDCCH and PDSCH detected each time have large power consumption, which is not favorable for saving power of the terminal.

2. DRX of RRC _ CONNECTED (RRC CONNECTED) state

The basic mechanism of DRX is to configure one DRX cycle (DRX cycle) for a UE in RRC _ CONNECTED state. One DRX cycle consists of "On Duration" and "Opportunity for DRX": in the time of "On Duration", the UE monitors and receives the PDCCH (active period); during the "Opportunity for DRX" time, the UE does not receive data of the downlink channel to save power consumption (sleep period).

Further, in order to save power consumption for blind detection of the Paging signal or PDCCH under the above two DRX scenarios, a wake-up signal (WUS) concept is proposed:

in each DRX cycle of the RRC idle state or the RRC connected state, or in the RRCconnected state (DRX OFF), before the UE blindly detects a Paging signal at PO (Paging occasion), the base station first transmits a wake-up signal to the UE, and the UE wakes up at a corresponding time to detect the wake-up signal. If the wake-up signal indicates the UE to blindly detect the Paging PDCCH, the UE continues to blindly detect a subsequent corresponding Paging PDCCH; otherwise, the UE does not blindly detect the Paging PDCCH.

However, since one PO time instant supports paging information transmission of a plurality of UEs in the existing LTE system. Therefore, if one wake-up signal corresponding to a Paging supports multiple UEs, if only one UE in the multiple UEs needs to be paged, the wake-up signals corresponding to all the UEs need to be designed to instruct all the UEs to detect the corresponding Paging PDCCH, so that all the UEs supported at the corresponding PO time can be woken up to blindly detect the Paging PDCCH, that is, the remaining UEs that do not need to be woken up are unnecessarily woken up to blindly detect the Paging PDCCH, and thus unnecessary power consumption is brought to the UEs.

In order to solve the above problem, embodiments of the present invention provide a signal transmission method and device, in which a network device groups X terminal devices mapped to a PO (i.e. divides X terminal devices with the same PO into N terminal device groups), and then sends first information (indicating the number of groups N, where N is an integer greater than 1) and M wake-up signals to a terminal device side, so as to indicate whether the terminal devices of the N terminal device groups monitor corresponding paging signals at a paging opportunity through the M wake-up signals, so that the X terminal devices mapped to a PO do not need to be unnecessarily woken up, thereby avoiding unnecessary power consumption of the terminal devices, and meanwhile, since one wake-up signal is used to indicate whether the terminal devices of all or part of the N terminal device groups monitor corresponding paging signals at the paging opportunity, the group number of all or part of terminal equipment groups is less than or equal to the first threshold value, so that the group number of the terminal equipment groups indicated by one awakening signal does not exceed the first threshold value, and the performance of the awakening signal is ensured.

As an example, in the embodiment of the present invention, fig. 1 illustrates that the terminal is a mobile phone.

The first embodiment:

the signal transmission method according to the embodiment of the present invention is described below with reference to a flow chart of the signal transmission method shown in fig. 2, where fig. 2 is a schematic flow chart of the signal transmission method according to the embodiment of the present invention, and for a network device side, the signal transmission method according to the embodiment of the present invention includes steps 201 and 202:

step 201: the network device transmits the first information.

Step 202: the network device sends M wake-up signals.

It should be noted that, the step 201 and the step 202 are only for distinguishing the steps, and the sequence of the steps is not limited, and in the specific implementation, the step 201 may be executed first and then the step 202 is executed, or the step 201 and the step 202 may be executed at the same time, which is not limited in the embodiment of the present invention.

In an embodiment of the present invention, the first information is used to indicate the number N; the number N is the number of terminal device groups obtained by grouping X terminal devices, and X, N is an integer greater than 1. The paging opportunities of the above-mentioned X terminal devices are the same, that is, the X terminal devices mapped to the same paging opportunity are divided into N terminal device groups.

It should be noted that the number N is less than or equal to a second threshold, where the second threshold is the maximum number of packets of the terminal device corresponding to the paging opportunity, and the second threshold is predefined or configured by the network device.

In the embodiment of the present invention, the M wake-up signals are used to indicate whether terminal devices in N terminal device groups monitor corresponding paging signals at the paging opportunity; m is a positive integer.

Optionally, in this embodiment of the present invention, a wake-up signal is used to indicate whether terminal devices of all or part of the N terminal device groups listen to a corresponding paging signal at the paging opportunity.

Optionally, the first threshold is the maximum number of groups of the terminal device supported by one wake-up signal, that is, one wake-up signal may indicate whether the maximum number of groups of the terminal device with the first threshold monitors the corresponding paging signal. It should be noted that the first threshold is a positive integer, and the first threshold is predefined or configured by the network device.

Further optionally, in an embodiment of the present invention, the wake-up signal includes a first identifier; the first identifier of one wake-up signal is used for indicating the working state of all or part of terminal equipment in the N terminal equipment groups; the above working state is used to indicate whether the corresponding terminal device monitors the corresponding paging signal at the paging opportunity. For example, when the first identifier is used to indicate that the terminal device is in an active state, it indicates that the first identifier is used to indicate that the terminal device listens to a corresponding paging signal at the paging opportunity, and when the first identifier is used to indicate that the terminal device is in a dormant state, it indicates that the first identifier is used to indicate that the terminal device does not listen to a corresponding paging signal at the paging opportunity.

For example, taking an example that one first identifier indicates two terminal device groups (terminal device group a (abbreviated as group a) and terminal device group B (abbreviated as group B)), group a and group B represent specific operating states by four different first identifiers, for example, by three different sequences and DTX, DTX is used to indicate that group a is in a sleep state and group B is in a sleep state, if index numbers corresponding to the three sequences are 0, 1, and 2, respectively, where:

sequence 0 is used to indicate that group a is in a sleep state and group B is in an active state;

sequence 1 is used to indicate that group a is in an active state and group B is in a dormant state;

sequence 2 is used to indicate that group a is active and group B is active.

For example, if the network device determines that group a is in a sleep state and group B is in an active state, it may send a wake-up signal to the terminal device side, and configure sequence 0 in the wake-up signal, so that when the terminal device in group a receives the wake-up signal, it may determine that it does not need to monitor a corresponding paging signal based on sequence 0 in the wake-up signal, and when the terminal device in group B receives the wake-up signal, it may determine that it monitors a corresponding paging signal based on sequence 0 in the wake-up signal.

In the embodiments of the present invention, the sequence-based WUS communication method described above is referred to as a CDM (code division multiplexing) method.

Illustratively, the sequence may be any one of a ZC (Zadoff-Chu) sequence, an M sequence, a Gold sequence, and a Walsh sequence or a product of at least two sequences; the sequence parameters of different sequences are different, wherein the sequence parameters comprise at least one of the following: root sequence, generator polynomial, cyclic shift, phase, Cover Code, and scrambling sequence.

Optionally, in this embodiment of the present invention, in a case that the wake-up signal includes the first identifier, before step 202, the method further includes the following steps:

step 202 a: and the network equipment determines a first identifier corresponding to each awakening signal according to the first mapping relation and the equipment identifier of the terminal equipment corresponding to each awakening signal.

Wherein, the first mapping relation comprises: the corresponding relation between the device identification of the X terminal devices and the Y first identifications; the device identifier of a terminal device corresponds to at least one first identifier.

For example, the network device may determine that several wake-up signals need to be sent specifically and the first identifier included in each wake-up signal based on the first mapping relationship, the device identifier of the terminal device included in each terminal device group of the N terminal device groups, and the operating state of each terminal device.

Optionally, in this embodiment of the present invention, the Y first identifiers may be distinguished by different sequences or DTX.

Optionally, in an embodiment of the present invention, the step 202 specifically includes the following steps:

step 202b 1: and the network equipment determines M target time-frequency resources according to the number N and the first threshold value.

Step 202b 2: the network equipment sends M awakening signals on M target time frequency resources, and one target time frequency resource corresponds to one awakening signal.

Optionally, in the embodiment of the present invention, if the network device does not start the function of sending the wake-up signal of the old version, the target time-frequency resource includes a second time-frequency resource; if the network device starts the function of sending the wake-up signal of the old version, the target time-frequency resource does not comprise a second time-frequency resource; the second time frequency resource is used for transmitting the resource of the wake-up signal of the old version. For example, when the WUS function of Release 15 is not started, the WUS of Release 16 may transmit through the time-frequency resources of the WUS of Release 15 (i.e., the time-frequency resources of the two overlap), or the time-frequency resources of the WUS of Release 16 may be determined through the WUS time-frequency resource determination method of Release 15.

Further optionally, in the embodiment of the present invention, the step 202b1 described above may be implemented in the following three implementation manners.

A first possible implementation:

illustratively, the step 202b1 includes the following steps:

step A1: the network device determines the number M according to the number N, a first threshold value, and a first rule.

Step A2: and the network equipment determines M target time-frequency resources according to the number M.

Wherein the first rule comprises: in the case where the number N is less than or equal to a first threshold, M is equal to 1; alternatively, when the number N is greater than the first threshold, the quotient of the number N and the first threshold is rounded up to obtain M (i.e., M is ceil (N/Z)), and for example, if the first threshold is Z, N is 3, and Z is 2, M is 2.

It should be noted that the first rule described above is protocol-specific or network device-configured.

For example, in the case that the number N is less than or equal to the first threshold, the network device only needs to use the CDM scheme to transmit the wake-up signal, and in the case that the number N is greater than the first threshold, the network device also needs to consider using the TDM (time division multiplexing) scheme and/or the FDM (frequency division multiplexing) scheme, as shown in table 1 below (where the first threshold Z is 2 corresponding to table 1):

TABLE 1

N	<＝2	>2
			CDM	Is that	Is that
TDM	Whether or not	Is that
			FDM	Whether or not	Is that

A second possible implementation:

illustratively, the step 202b1 includes the following steps:

step B1: and under the condition that the number N is less than or equal to a first threshold value, the network equipment takes the first time-frequency resource as a target time-frequency resource.

Wherein, the interval between the starting time of the first time-frequency resource and the starting time of the paging opportunity is associated with a first time interval. For example, the network device may determine a first time-frequency resource on which an actual duration of the wake-up signal transmitted does not exceed a maximum duration of the wake-up signal based on a starting time of the paging opportunity and a first time interval.

It should be noted that this first time interval is protocol specified or network device configured.

A third possible implementation:

illustratively, the step 202b1 includes the following steps:

step C1: and under the condition that the number N is greater than the first threshold value, the network equipment determines M target time-frequency resources according to the equipment identifications of the X terminal equipment and a second rule.

Wherein the second rule comprises at least one of: the second mapping relation, the interval between the starting time of the first target time frequency resource and the starting time of the paging opportunity are associated with the first time interval; the first target time-frequency resource is the last target time-frequency resource in the M target time-frequency resources; the second mapping relationship is a corresponding relationship between the device identifiers of the X terminal devices and the M target time-frequency resources, and the device identifier of one terminal device is mapped to one target time-frequency resource. For example, the second mapping relationship may be: and mapping the device identifications of the X terminal devices to the M target time-frequency resources through a hash function.

It should be noted that, in this embodiment, the mapping between the device identifier of the terminal device and the target time-frequency resource is not limited to be performed by a hash function, and may also be performed by other manners, for example, the mapping relationship between the device identifier of the terminal device and the target time-frequency resource is predefined by the base station and the terminal, which is not limited in this invention.

The device identifier of the terminal device referred to in this patent may be: an International Mobile Subscriber Identity (IMSI), a Packet-domain Subscriber Temporary identifier (P-TMS), a Subscriber Temporary identifier (TMS), or a Short format Subscriber Temporary identifier (TMS), and the like.

Further, the second rule includes: when the M target time frequency resources are TDM, the time interval between the M target time frequency resources is associated with a second time interval; or, when the M target time-frequency resources are FDM, the frequency domain interval between the M target time-frequency resources is associated with the first frequency domain interval. It should be noted that the second rule, the first time interval, the second time interval, the first frequency domain interval, described above, are protocol specified or network device configured.

Illustratively, if the terminal device side knows that R15(Release 15) turns on the WUS function (R15 signals whether the terminal device turns on the WUS function), and R16 needs to transmit 1 wake-up signal, the start time of the wake-up signal transmitted by R16(Release 16) is before the start time of the wake-up signal transmitted by R15, and the interval between the two is a third time interval. The third time interval may be 0 or greater than 0. If R16 needs to send 2 wake-up signals, the start time of the first wake-up signal can be determined according to the first time interval and the start time of the paging opportunity, and the start time of the second wake-up signal is before the start time of the first wake-up signal with a second time interval in between, so that the target time frequency resources of all wake-up signals can be determined.

If the terminal device side knows that the R15 does not turn on the WUS function (the R15 signaling informs the terminal device whether to turn on the WUS function), if the R16 needs to transmit 1 wake-up signal, the starting time of the R16 transmitting the wake-up signal may coincide with the starting time of the R15 transmitting the wake-up signal, or reuse the time domain resource used by the R15 transmitting the wake-up signal; if R16 needs to send 2 wake-up signals, the start time of the first wake-up signal can be determined according to the first time interval and the start time of the paging opportunity, and the start time of the second wake-up signal is before the start time of the first wake-up signal with a second time interval in between, so that the target time frequency resources of all wake-up signals can be determined.

Optionally, in an embodiment of the present invention, the method further includes:

step 203: the network device transmits the second information.

Wherein the second information is used to indicate transmission modes of M wake-up signals, and the transmission modes include at least one of the following: a CDM scheme, and at least one of a TDM scheme and an FDM scheme.

For example, the second information may carry different second identifiers to indicate transmission manners of the M wake-up signals, for example, as shown in table 2 below:

TABLE 2

Second label	1	2	3	4	5	6
							Means of	CDM	TDM	FDM	CDM+TDM	CDM+FDM	CDM+FDM+TDM

When the second identifier is 1, it indicates that the transmission mode of the M wake-up signals is a CDM mode, when the second identifier is 2, it indicates that the transmission mode of the M wake-up signals is a TDM mode, when the second identifier is 3, it indicates that the transmission mode of the M wake-up signals is an FDM mode, when the second identifier is 4, it indicates that the transmission mode of the M wake-up signals is a CDM + TDM mode, when the second identifier is 5, it indicates that the transmission mode of the M wake-up signals is a CDM + FDM mode, and when the second identifier is 6, it indicates that the transmission mode of the M wake-up signals is a CDM + FDM + TDM mode.

It should be noted that 1, 2, 3, 4, 5, and 6 are only examples, and other numbers or symbols may be used to represent the examples in practical applications, and the present invention is not limited thereto.

In the signal transmission method provided by the embodiment of the present invention, the network device groups X terminal devices mapped to one paging opportunity (i.e., the X terminal devices with the same paging opportunity are divided into N terminal device groups), and then sends the first information (used to indicate the number N of groups, where N is an integer greater than 1) and M wake-up signals to the terminal device side, so as to indicate whether the terminal devices of the N terminal device groups monitor corresponding paging signals at the paging opportunity through the M wake-up signals, thereby reducing unnecessary power consumption of the terminal devices. Meanwhile, one wake-up signal is used for indicating whether all or part of the terminal devices in the N terminal device groups monitor the corresponding paging signal at the paging opportunity, and the group number of all or part of the terminal device groups is less than or equal to the first threshold, so that the group number of the terminal devices indicated by one wake-up signal does not exceed the first threshold, the performance of the wake-up signal is ensured, and the reliability and effectiveness of communication can be improved.

Second embodiment:

the signal transmission method according to the embodiment of the present invention is described below with reference to a signal transmission method flowchart shown in fig. 3, where fig. 3 is a schematic flowchart of a signal transmission method according to the embodiment of the present invention, and for a terminal device side, the signal transmission method according to the embodiment of the present invention includes steps 301 to 304:

step 301: the first terminal device receives first information from the network device.

Step 302: and the first terminal equipment determines a second target time frequency resource according to the first information.

Step 303: and the first terminal equipment receives the wake-up signal on the second target time frequency resource.

Step 304: and the first terminal equipment determines whether to monitor the paging signal corresponding to the wake-up signal according to the wake-up signal.

In this embodiment of the present invention, the wake-up signal is used to indicate whether all or some terminal devices in the N terminal device groups monitor a corresponding paging signal at the paging opportunity.
