Description

Information transmission method, network device, terminal, and computer-readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a network device, a terminal, and a computer-readable storage medium.

Background

In the fourth generation (4)^thGeneration, 4G) and fifth Generation (5)^thGeneration, 5G) communication system, a terminal in a Radio Resource Control idle (RRC _ idle) state of a Radio Resource Control layer needs to detect a paging signal sent by a network device at a pre-configured time, and a specific paging signal process is as follows: blind detecting a Physical Downlink Control Channel (PDCCH) corresponding to a Paging Radio Network Temporary Identity (P-RNTI), and if the PDCCH is not detected, ending the detection; if the presence of the PDCCH is detected, a Physical Downlink Shared Channel (PDSCH) indicated by the PDCCH is further detected, and if the detected PDSCH is not a paging signal of the terminal, the detection is terminated. In the RRC _ idle state, the terminal periodically detects paging signals, and power consumption for detecting the PDCCH and the PDSCH each time is large, but the probability of detecting paging signals belonging to the terminal is low, which is not favorable for power saving of the terminal.

Further, in a Discontinuous Reception (DRX) scenario, the basic mechanism of DRX is: a terminal in a connected (RRC _ connected) state is configured with a DRX cycle (cycle), as shown in fig. 1, fig. 1 shows a time domain diagram of the DRX cycle, where the DRX cycle includes an active period (On Duration) in which the terminal monitors and receives a PDCCH, and a dormant period (Opportunity for DRX) in which the terminal does not receive data of a downlink channel to save power consumption. In most cases, after a terminal is scheduled to receive or transmit data in a certain subframe, it is likely to continue to be scheduled in the next several subframes, and if it waits for the next DRX cycle to receive or transmit, the data will cause extra delay. To reduce such delays, the terminals may remain in the active period after being scheduled. Specifically, when the terminal is scheduled to initially transmit data, a timer is started or restarted, and the terminal is always in an active period during the time that the timer is not overtime.

However, not every terminal within a DRX cycle is scheduled, and therefore, unnecessary paging signals and blind detection of the PDCCH may still occur. In addition, although the terminal needs a function of time and frequency synchronization based on the received signal in order to be able to correctly receive the signal, the terminal does not receive the signal for a long time in the DRX and RRC _ idle states, and when the terminal starts receiving next time, the time and frequency synchronization may be lost, which may affect the reception performance of the reception opening time signal.

Further, the RRC protocol defines the configuration related to the measurement and the event reported by the measurement. And the terminal measures all cells in the service cell and the storage cell list according to the measurement configuration and reports the measurement result. The measurement reporting may be a periodic reporting or an event trigger. For a serving cell, when a connected DRX is not configured, if a measurement report is configured, a measurement Sample (Sample) needs to be available within a certain measurement duration (e.g., 200 ms); if no measurement report is configured, the measurement needs to be performed for downlink synchronization. When connected DRX is configured, the measurement requirements are set according to DRX cycle, such as at least one measurement sample within a certain measurement duration (N DRX cycles). Radio Resource Management (RRM) measurement is performed periodically, which results in a large number of invalid measurements performed by the UE, thereby increasing the power consumption of the UE and increasing the overhead of network resources.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Further, the use of "and/or" in the specification means at least one of the connected objects.

As shown in fig. 2, the information transmission method according to the embodiment of the present invention is applied to a network device, and specifically includes the following steps:

step 21: and configuring discretely distributed target transmission resources for the terminal in the Discontinuous Reception (DRX) state or the idle state.

The network device may schedule discretely distributed target transmission resources for terminals in a discontinuous reception, DRX, state or an idle state. Wherein the discretely distributed target transmission resources are mainly used for transmitting the indication sequence. Wherein the target transmission resource comprises a time domain transmission resource and a frequency transmission resource.

Step 22: and sending the indication sequence to the terminal through the target transmission resource.

The indication sequence is used for indicating whether the terminal detects a Physical Downlink Control Channel (PDCCH) in the next DRX period or not and whether at least one of measurement and report of Radio Resource Management (RRM) is performed or not. The next DRX cycle refers to a DRX cycle next to the DRX cycle in which the target transmission resource is located, and in terms of the terminal side, the terminal detects the DRX cycle next to the DRX cycle in which the indication sequence is located. The network device configures an energy-saving signal for the terminal in the DRX state or the idle state, where the energy-saving signal is an indication sequence. The indication sequence is used for indicating whether the terminal detects a Physical Downlink Control Channel (PDCCH) in the next DRX period or not and whether at least one of measurement and report of Radio Resource Management (RRM) is performed or not. In particular, the indication sequence is in particular a Wake-up Signal (WUS) and/or a Sleep Signal (Go To Sleep Signal (GTS). The WUS is used for indicating that PDCCH detection or RRM measurement and reporting are required in the next DRX period. The GTS is used for indicating that PDCCH detection or RRM measurement and reporting are not needed in the next DRX period. It is worth pointing out that RRM measurement and reporting may include: and only RRM measurement or both RRM measurement and reporting the measurement result.

Specifically, assuming that the indication sequence configured for the terminal by the network device is a WUS, the terminal may detect the WUS on the target transmission resource, and if the WUS is detected, it is determined that PDCCH detection and/or RRM measurement and reporting are/is required in the next DRX cycle, and if the WUS is not detected, it is determined that the PDCCH is not required or the RRM measurement and reporting are not required in the next DRX cycle. Similarly, assuming that the indication sequence configured for the terminal by the network device is GTS, the terminal may detect GTS on the target transmission resource, and if GTS is not detected, determine that PDCCH detection is required or RRM measurement and reporting is required in the next DRX cycle, and if GTS is detected, determine that PDCCH is not required and RRM measurement and reporting is not required in the next DRX cycle. It is worth pointing out that the network device may also configure the WUS and the GTS for the terminal, when detecting the WUS, perform PDCCH detection and/or RRM measurement and reporting in the next DRX cycle, and when detecting the GTS, continue to sleep.

And sending an indication sequence to the terminal through the discretely distributed target transmission resources, specifically, mapping the indication sequence to the discretely distributed target transmission resources for sending, wherein the discretely distributed resource pattern may be predefined by a standard or autonomously configured by the network device for the terminal. For example, the indication sequence is discretely distributed on B Physical Resource Blocks (PRBs), occupies X slots (slots), and has an interval S between two adjacent OFDM symbols in N OFDM symbols (e.g., OFDM symbols) on N time domain symbols in each slot_tOne OFDM symbol, and S is occupied in every 12 subcarriers (subcarriers) in the frequency direction_fAnd (4) sub-carriers. Where each slot contains 14 OFDM symbols. Specifically, reference may be made to the scheme shown in fig. 3, where X is 2, B is 50, N is 2, St is 7, and S is_fThe target transmission resource is the part of the graph that identifies the grid line, 3.

Further, step 21 can be implemented in the following two ways.

Determining a time domain transmission position according to a configured Paging Opportunity (PO) and an active period (DRX On duration) of a DRX period; and configuring discretely distributed target transmission resources for the terminal in the discontinuous reception DRX state or the idle state according to the time domain transmission position.

Wherein the time domain transmission positions comprise: at least one of a time domain transmission frame (frame), a time domain transmission subframe (subframe), a time domain transmission slot (slot), and a Physical Resource Block (PRB).

Specifically, in the method of the first mode, the time domain transmission position is determined by using the transmission position with the distance from the time domain initial transmission position of the configured paging opportunity PO and the active period of the DRX cycle as the preset advance offset value. That is, the starting slot/PRB (or PRB index) of the target transmission resource for transmitting the indication sequence may be configured to the terminal through signaling, where the configuration may be in the form of an advance offset value of the slot/subframe starting from the PO/DRX On duration. That is, after acquiring the time domain initial transmission positions of the activation periods of the PO and DRX cycles of the paging opportunities and the target transmission resources and the offset values of the advance amounts thereof, the specific positions of the target transmission resources can be determined.

Determining a time domain transmission position according to at least one item of identity information of the terminal and cell ID information of a cell to which the terminal belongs; and configuring discretely distributed target transmission resources for the terminal in the discontinuous reception DRX state or the idle state according to the time domain transmission position.

Wherein the time domain transmission positions comprise: at least one of a time domain transmission frame, a time domain transmission subframe, and a time domain transmission slot; the identity information of the terminal includes: at least one of ID information of a terminal and ID information of a terminal group (group) in which the terminal is located. That is to say, the target transmission resource for transmitting the indication sequence, especially the time domain transmission resource frame/subframe/slot/PRB of the target transmission resource, may be related to the identity information of the terminal or the cell ID information where the terminal is located, and the target transmission resource for the indication sequence of different terminals may be determined through the terminal identity information or the cell ID where the terminal is located.

Further, in both the first and second manners, a manner of determining a corresponding target transmission resource according to the time domain transmission position is adopted, and specifically, according to at least one of identity information of the terminal and cell ID information of a cell to which the terminal belongs, time domain symbol number information and frequency domain subcarrier number information in the time domain transmission position are determined; and configuring discretely distributed target transmission resources for the terminal in the discontinuous reception DRX state or the idle state according to the time domain symbol number information and the frequency domain subcarrier number information. Wherein, the frequency domain subcarrier number information includes: a subcarrier offset. Specifically, the number of the OFDM symbol occupied by the target transmission resource and the offset of the subcarrier are related to the terminal identity information and/or the ID information of the cell in which the terminal is located. That is, the position of the starting OFDM symbol of the target transmission resource of the transmitted indication sequence in the Slot can be determined according to the terminal identity information and/or the ID information of the cell in which the terminal is located. For example, the starting position of the OFDM symbol in the current slot is determined by mod (terminal ID, 3) + 2. Similarly, the starting subcarrier position of the target transmission resource of the transmission indication sequence in the Slot where the target transmission resource is located may also be determined according to the terminal identity information and/or the ID information of the cell where the terminal is located. For example, the calculation of mod (cell ID, 4) is used to determine the subcarrier number (or subcarrier position) starting in the current slot. It should be noted that the starting subcarrier position on each OFDM symbol may be the same or different.

Further, the indication sequence is used for indicating the index number information of the terminal or the group where the terminal is located; wherein, the sequence parameters of the different indication sequences indicate the index number information of different terminals or different terminal groups. Wherein the indication sequence may be at least one of a ZC sequence, an m-sequence and a Gold sequence. When the indication sequence is a ZC sequence, indicating index number information of different terminals or different terminal groups by at least one ZC sequence with different root sequences and cyclic shift values; when the indication sequence is an m sequence, generating index number information of different terminals or different terminal groups, wherein the m sequence with different at least one of the polynomial and the cyclic shift value indicates the index number information of the different terminals or the different terminal groups; and when the indication sequence is a Gold sequence, generating index number information of different terminals or different terminal groups, wherein the Gold sequence with different at least one of the polynomial, the shift value and the initialization mode is different.

The following description will take the indication sequence as Gold sequence as an example. One Gold sequence is an exclusive or of 2M sequences, and the length of the output Gold sequence c (n) is M, where n is 0, 1. The Gold sequence can be initialized as follows:

c(n)＝(x₁(n+N_c)+x₂(n+N_c) Mod2 formula one

x₁(n+31)＝(x₁(n+3)+x₁(n)) mod2 equation two

x₂(n+31)＝(x₂(n+3)+x₂(n+2)+x₂(n+1)+x₂(n)) mod2 equation three

Wherein N is_cRepresenting the shift value of the Gold sequence, N_c＝1600，x₁Is x₁(0)＝1，x₁(n)＝0，n＝0,1,…,30，x₂Is initialized to

Wherein the content of the first and second substances,

is ID, U, of a cell or virtual cell_IDThe ID information of different terminals or the ID information of the group in which the terminal is located.

Further, if both the wake-up signal and the sleep signal are indicated by way of initialization, the initialization is performed in a manner other than the same as that of the sleep signal

And U_IDRelevant, also specifically relevant to wake/sleep indication. Specifically, the initialization mode is

Where I ∈ {0,1} indicates a wake indication and a sleep indication, respectively. Or, I ∈ {0,1} is used to indicate whether RRM measurement and reporting is performed.

The second and third equations represent a generator polynomial for generating 2 m sequences, and the transmitted gold sequence is d (n) -1-2 c (n).

Specifically, the number of symbols of the WUS sequence is assumed to be S, and S ═ X × N × B × S_fIf the symbol mapped on the upper time-frequency resource is QPSK modulated on the Gold sequence generated above, the length M of the Gold sequence c (n) is 2 × S; the symbol of the indication sequence mapped to the target transmission resource is:

where, r (S) is time domain symbol number information in the time domain transmission resource, and S is 0,1, … S-1.

Further, the sequence parameter of the indication sequence may be predefined, or may be dynamically generated by the network device according to at least one of the identity information of the terminal and the cell ID information of the cell to which the terminal belongs. Before step 22, the method further comprises: and configuring an indication sequence for the terminal. The configuration can be specifically carried out in the following way:

and configuring an indication sequence for the terminal according to the predefined sequence parameters in a first configuration mode.

Determining sequence parameters according to at least one item of identity information of the terminal in the DRX state and cell ID information of a cell to which the terminal belongs; and configuring an indication sequence for the terminal according to the sequence parameter. Wherein, the identity information of the terminal comprises: at least one of ID information of the terminal and ID information of a terminal group in which the terminal is located. Wherein, the network device can configure the sequence parameter to the terminal through RRC signaling.

In the information transmission method of the embodiment of the invention, the network device sends the indication sequence to the terminal through the transmission resources which are distributed discretely, wherein the indication sequence is used for indicating whether the terminal needs to perform at least one of PDCCH detection and RRM measurement and report in the next DRX period, and the terminal determines whether to perform the PDCCH detection or the RRM measurement and report according to the indication sequence, so that the terminal is prevented from performing the PDCCH detection or the RRM measurement and report in each DRX period, and the signal processing power consumption of the terminal in the DRX state is reduced.

The network device in the embodiment of the invention sends the indication sequence to the terminal through the discretely distributed transmission resources, wherein the indication sequence is used for indicating whether the terminal needs to perform at least one of PDCCH detection and RRM measurement and report in a DRX period, and the terminal determines whether to perform the PDCCH detection or the RRM measurement and report according to the indication sequence, so that the condition that the terminal performs the PDCCH detection in each DRX period or does not need the RRM measurement and report is avoided, and the signal processing power consumption of the terminal in the DRX state is reduced.

The above embodiment describes the information transmission method of the present invention from the network device side, and the following embodiment further describes the information transmission method at the terminal side with reference to the drawings.

As shown in fig. 6, the information transmission method according to the embodiment of the present invention is applied to a terminal side, and specifically includes the following steps:

step 61: discretely distributed target transmission resources are detected.

The process of detecting the target transmission resource specifically includes acquiring location information of the target transmission resource in discrete distribution, and performing signal detection at a corresponding location information.

Step 62: and detecting the indication sequence sent by the network equipment through the target transmission resource.

The indication sequence is used for indicating whether the terminal detects a Physical Downlink Control Channel (PDCCH) in the next DRX period or not and whether at least one of measurement and report of Radio Resource Management (RRM) is performed or not. In particular, the indication sequence is in particular a Wake-up Signal (WUS) and/or a Sleep Signal (Go To Sleep Signal (GTS). The WUS is used for indicating that PDCCH detection or RRM measurement and reporting are required in the next DRX period. The GTS is used for indicating that PDCCH detection or RRM measurement and reporting are not needed in the next DRX period. It is worth pointing out that RRM measurement and reporting may include: and only RRM measurement or both RRM measurement and reporting the measurement result.

Wherein, step 61 specifically includes: determining a time domain transmission position according to the obtained activation periods of the PO and DRX periods; and determining the target transmission resources in discrete distribution according to the time domain transmission position, and detecting the target transmission resources.

Wherein the time domain transmission positions comprise: at least one of a time domain transmission frame, a time domain transmission subframe, a time domain transmission slot, and a physical resource block.

The step of determining the time domain transmission position according to the acquired activation periods of the paging opportunity PO and the DRX cycle comprises the following steps: and determining the transmission position which has the distance from the acquired time domain initial transmission position of the activation period of the paging opportunity PO and the DRX period as the transmission position of the preset lead offset value as the time domain transmission position.

Specifically, a starting slot/PRB (or PRB index) in a target transmission resource of a transmission indication sequence may be obtained by receiving a signaling sent by a network device, where a configuration manner may be in the form of an advance offset value of a slot/subframe starting from a PO/DRX On duration. That is, after acquiring the time domain initial transmission positions of the activation periods of the PO and DRX cycles of the paging opportunities and the target transmission resources and the offset values of the advance amounts thereof, the specific positions of the target transmission resources can be determined.

Further, step 61 specifically includes: determining a time domain transmission position according to at least one of identity information of a terminal and cell ID information of a cell to which the terminal belongs; and determining the target transmission resources in discrete distribution according to the time domain transmission position, and detecting the target transmission resources. Wherein the time domain transmission positions comprise: at least one of a time domain transmission frame, a time domain transmission subframe, and a time domain transmission slot; the identity information of the terminal includes: at least one of ID information of the terminal and ID information of a terminal group in which the terminal is located. That is to say, the target transmission resource for transmitting the indication sequence, especially the time domain transmission resource frame/subframe/slot/PRB of the target transmission resource, may be related to the identity information of the terminal or the cell ID information where the terminal is located, and the target transmission resource for the indication sequence of different terminals may be determined through the terminal identity information or the cell ID where the terminal is located.

Wherein, the step of determining the discretely distributed target transmission resources according to the time domain transmission positions comprises: determining time domain symbol number information and frequency domain subcarrier number information in a time domain transmission position according to at least one of identity information of a terminal and cell ID information of a cell to which the terminal belongs; and determining discretely distributed target transmission resources according to the time domain symbol number information and the frequency domain subcarrier number information. Wherein, the frequency domain subcarrier number information includes: a subcarrier offset. That is, the position of the starting OFDM symbol of the target transmission resource of the transmitted indication sequence in the Slot can be determined according to the terminal identity information and/or the ID information of the cell in which the terminal is located. For example, the starting position of the OFDM symbol in the current slot is determined by mod (terminal ID, 3) + 2. Similarly, the starting subcarrier position of the target transmission resource of the transmission indication sequence in the Slot where the target transmission resource is located may also be determined according to the terminal identity information and/or the ID information of the cell where the terminal is located. For example, the calculation of mod (cell ID, 4) is used to determine the subcarrier number (or subcarrier position) starting in the current slot. It should be noted that the starting subcarrier position on each OFDM symbol may be the same or different.

Further, after step 62, the method further includes: and determining whether to detect the PDCCH in the next DRX period and at least one of measurement and report of Radio Resource Management (RRM) according to the indication sequence.

The indication sequence is used for indicating the index number information of the terminal or the terminal group where the terminal is located, which carries out PDCCH detection, RRM measurement and reporting, and/or the index number information of the terminal or the terminal group where the terminal is located, which does not carry out PDCCH detection, RRM measurement and reporting; the sequence parameters of the different indication sequences indicate the index number information of different terminals or different terminal groups.

Specifically, the indication sequence includes at least one of the following sequences:

Further, the step of determining whether to perform PDCCH detection and at least one of RRM measurement and reporting in the next DRX cycle according to the indication sequence includes: if the indication sequence indicates that the PDCCH needs to be detected in the DRX period, detecting the PDCCH; and if the indication sequence indicates that RRM measurement and report are required, performing RRM measurement and report.

Specifically, at the receiving start time in the DRX state or the idle state, the terminal performs sequence detection of an indication sequence on a predefined or scheduled target transmission resource in advance, and if it is detected that a corresponding sequence indication wakes up, the terminal performs PDCCH according to the indication and PDSCH detection after PDCCH detection.

Or, at the receiving start time of the DRX state or the idle state, the terminal performs sequence detection of an indication sequence on a predefined or scheduled target transmission resource in advance, and if it is detected that the corresponding sequence indication is awake, the terminal performs RRM measurement according to the indication and performs measurement reporting at the next RRM reporting time, the predefined time, or a preconfigured time.

Further, the terminal may further perform time-frequency fine synchronization by using the indication sequence transmitted in the target transmission resource, and specifically after step 61, the method further includes: performing channel estimation on the target transmission resources in discrete distribution to obtain corresponding channel estimation results; and performing time-frequency fine synchronization according to the channel estimation result. Specifically, the terminal detects an indication sequence on a target transmission resource which is discretely distributed, performs channel estimation based on the indication sequence, and performs estimation of a power delay spectrum and a frequency offset based on a channel estimation result; adjusting the windowing receiving time of the next receiving opening time of the terminal in the DRX state or the idle state according to the power delay spectrum; and according to the estimated frequency offset, performing frequency offset compensation on the next received signal to realize time-frequency fine synchronization.

In the information transmission method of the embodiment of the present invention, the terminal receives an indication sequence sent by the network device through the discretely distributed transmission resources, where the indication sequence is used to indicate whether the terminal needs to perform at least one of PDCCH detection and RRM measurement and reporting in the next DRX cycle, and the terminal determines whether to perform PDCCH detection or RRM measurement and reporting according to the indication sequence, so that the terminal is prevented from performing PDCCH detection or RRM measurement and reporting in each DRX cycle, and power consumption of signal processing of the terminal in the DRX state is reduced.
