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 detection Paging radio network temporary identifier (Paging Rad)A Physical Downlink Control Channel (PDCCH) corresponding to an io Network temporal 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). For the neighbor cells, the terminal needs to measure the 8 strongest cells at most, and particularly when to obtain measurement samples, may depend on the implementation of the terminal. When judging whether intra-frequency neighbor cells are to be measured for the purpose of cell reselection, when a serving cell meets a preset condition (such as Srxlev > SIntrASearchP and Square > SIntrASearchQ), a terminal selects not to perform measurement of the same-frequency neighbor cells; if the threshold value is lower, the measurement of the same-frequency neighbor cell needs to be performed. In addition, for the Inter-frequency adjacent cell scene, the serving cell and the adjacent cell use different frequencies (Inter frequency) and Radio Access technologies (Inter-Radio Access technologies, Inter-RATs) of different Access networks, and when the priority of the frequency point and the RAT of the adjacent cell is higher than that of the frequency point and the RAT of the serving cell, the terminal performs measurement of the adjacent cell according to the measurement requirement defined by the protocol. When the priority is equal to or lower than the frequency point and RAT of the serving cell, when the serving cell meets a preset condition (such as Srxlev > SnonIntraSearchP and Square > SnonIntraSearchQ), the terminal selects not to execute measurement of the neighbor cell; if it is below the threshold value, measurements of the neighbor cells need to be performed. Therefore, Radio Resource Management (RRM) measurement is performed periodically, which results in a large amount of invalid measurement performed by the UE, thereby increasing the power consumption of the UE and increasing the overhead of network resources.

Further, the use of "and/or" in the specification means at least one of the connected objects. The use of "/" 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 a physical channel for the terminal in the Discontinuous Reception (DRX) state or the idle state.

The network device may schedule a specific physical channel for a terminal in a discontinuous reception, DRX, state or an idle state. The specific physical channel is mainly used for transmitting indication information, and specifically may be a special physical channel defined by a system, or a common physical channel scheduled by a network device for a terminal. The configuring of the physical channel by the network device herein particularly refers to configuring transmission resources occupied by the physical channel, and specifically includes time domain transmission resources and frequency domain transmission resources.

Step 22: and sending the indication information to the terminal through the physical channel.

The indication information includes an indication field for indicating whether the terminal performs detection of a Physical Downlink Control Channel (PDCCH) in a next DRX period and at least one of measurement and reporting of Radio Resource Management (RRM). The next DRX cycle here refers to a DRX cycle next to the DRX cycle in which the transmission resource of the indication information is detected, and in terms of the terminal side, the terminal detects the DRX cycle next to the DRX cycle in which the indication information is detected. The indication field comprises at least one indication bit, and one indication bit is used for indicating whether to detect a Physical Downlink Control Channel (PDCCH) in the next DRX period or indicating whether to measure and report Radio Resource Management (RRM). When the indication field comprises a plurality of indication bits, the detection of the physical downlink control channel PDCCH and the measurement and reporting of the radio resource management RRM can be jointly indicated in the next DRX period.

Specifically, the indication information is specifically 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.

As shown in fig. 3, when it is assumed that the indication information configured for the terminal by the network device is a PDCCH detection indication, the terminal may detect the PDCCH detection indication on a physical channel, determine that PDCCH detection is required in a next DRX cycle if the PDCCH detection indication is detected, and determine that PDCCH detection is not required in the next DRX cycle if the PDCCH detection indication is not detected, and continue to maintain the sleep state.

Similarly, as shown in fig. 4, when it is assumed that the indication information configured for the terminal by the network device is an RRM measurement and reporting indication, the terminal may detect the RRM measurement and reporting indication on the physical channel, determine that the RRM measurement and reporting is required if the RRM measurement and reporting indication is detected, determine that the RRM measurement and reporting is not required if the RRM measurement and reporting indication is not detected, and continue to maintain the dormant state.

Further, the indication information includes at least two indication fields, where the at least two indication fields are used to respectively indicate whether different terminals or different terminal groups perform detection of a physical downlink control channel PDCCH in a next DRX cycle and at least one of measurement and reporting of radio resource management RRM. That is, the indication fields of a plurality of different terminals or a plurality of different terminal groups may be combined into one piece of indication information, i.e., the indication information may combine the sleep indication signals or the wake indication signals of a plurality of terminals or a plurality of terminal groups. The terminal group includes at least two terminals, and the number of the terminals included in the terminal group is not particularly limited, that is, one indication field in the indication information may wake up one terminal or one group of terminals. For example, the indication information includes N indication fields (or called sleep indication signals or wake indication signals) to indicate N terminals or N groups of terminals. For example, taking an example that the indication field includes one indication bit, where 0 represents sleep, 1 represents wake-up, the bit stream corresponding to the indication information is 10010011, and if 8 terminals are indicated, the 1 st, 4 th, 7 th and 8 th terminals are woken up; if 8 groups of terminals are indicated, groups 1, 4, 7 and 8 terminals are woken up. The position of the indication field corresponding to the terminal or the terminal group in the indication information may be predefined, or may be dynamically configured through RRC signaling, or calculated according to at least one of the ID information of the terminal and the ID information of the terminal group (group) where the terminal is located.

Preferably, the step 21 specifically includes: coding the indication information by a preset coding mode; and transmitting the coded indication information to the terminal through a physical channel. Wherein, the preset coding mode comprises: a repetition (repetition) code, an rm (reed muller) code, a Polar code, an LDPC code, a convolutional code, and a Turbo code. That is, the indication information generates at least one of a repetition code, an RM code, a Polar code, an LDPC code, a convolutional code, and a Turbo code in a coding manner, and the coded indication information is transmitted to the terminal through a physical channel. The specific encoding mode can be realized by adopting a linear encoding mode so as to reduce the decoding complexity.

Further, the step 21 can be specifically realized by the following two ways:

determining a time domain transmission position of a physical channel according to a configured Paging Opportunity (PO) and a time domain position of an active period (DRX On duration) of a DRX period; and configuring the transmission resource of the physical channel 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), and a time domain transmission slot (slot).

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 time domain starting position of the physical channel for transmitting the indication information may be configured to the terminal through signaling, where the configuration manner may be in the form of an advance offset value of slot/subframe starting from PO/DRX On duration. That is, after acquiring the time domain initial transmission positions of the activation periods of the PO and DRX cycles, and after acquiring the transmission resources of the physical channel and the offset value of the advance thereof, the position of the time domain transmission resources of the physical channel can be determined.

Further, the OFDM symbols and subcarriers occupied by the physical channel may be predefined or configured to the terminal by the network device through Radio Resource Control (RRC) signaling, and may also be related to the terminal identity information and the like. Specifically, the step of configuring the transmission resource of the physical channel for the terminal in the discontinuous reception DRX state or the idle state according to the time domain transmission position includes: and determining time domain symbol number information and frequency domain subcarrier number information in the time domain transmission position 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. And configuring transmission resources of a physical channel 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 specifically occupied by the physical channel 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 to say, the position of the starting OFDM symbol in the slot where the physical channel is located may be determined according to the terminal identity information and/or the ID information of the cell where 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 in the slot where the physical channel 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. Further, the ID numbers of different terminals belonging to the same group may be different, but the starting position and the starting subcarrier position of the OFDM symbol calculated for the same group should be the same, so the calculation method should satisfy that the calculation results of the terminals of the same group are the same, for example, the ID of a second terminal of a certain group is taken for calculation, which is the criterion for the transmission resources of the physical channels corresponding to all terminals in the group. It should be noted that the starting subcarrier position on each OFDM symbol may be the same or different.

Determining a time domain transmission position of a physical channel, and time domain symbol number information and frequency domain subcarrier number information in the 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 configuring transmission resources of a physical channel 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 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 item of ID information of the terminal and ID information of a terminal group in which the terminal is located, wherein the frequency domain subcarrier number information comprises: a subcarrier offset. That is, the transmission resource of the physical channel for transmitting the indication information may be related to the identity information of the terminal or the ID information of the cell where the terminal is located, and the transmission resource of the physical channel for different terminals may be determined by the identity information of the terminal or the ID of the cell where the terminal is located.

Specifically, the network device may use a Tracking Reference Signal (TRS) as a demodulation pilot Signal of the physical channel, and step 21 specifically includes: configuring a target transmission resource of a tracking reference signal TRS; and configuring a physical channel for the terminal in the Discontinuous Reception (DRX) state or the idle state in the frequency domain range of the target transmission resource.

The target transmission resource of the TRS may be predefined, or may be configured to the terminal by the network device through RRC signaling. In addition, the network device may also calculate and determine a target transmission resource of the TRS according to a specific parameter. The method can be specifically realized by the following configuration mode:

determining a time domain transmission position of a tracking reference signal TRS according to a configured time domain position of a paging opportunity PO and an activation period of a DRX period; and configuring target transmission resources of the TRS 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.

Specifically, the step of configuring the target transmission resource of the TRS according to the time domain transmission position includes: determining time domain symbol number information and frequency domain subcarrier number information in a time domain transmission position according to at least one of the identity information of the terminal and cell ID information of a cell to which the terminal belongs; and configuring target transmission resources of the TRS 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. It should be noted that the determination of the time domain transmission position of the TRS is similar to the determination of the time domain transmission position of the physical channel, and the specific determination may be implemented by referring to the manner of determining the time domain transmission position of the physical channel described in the above manner one, and therefore, details are not described herein again.

Determining a time domain transmission position of a tracking reference signal TRS, and time domain symbol number information and frequency domain subcarrier number information in the 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 configuring target transmission resources of the TRS according to the time domain symbol number information and the frequency domain subcarrier number information. 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 item of ID information of the terminal and ID information of a terminal group in which the terminal is located, wherein the frequency domain subcarrier number information comprises: a subcarrier offset.

Specifically, the offset of the target transmission resource of the TRS may be classified into three types:

1. the frequency domain offset of the target transmission resource of the TRS is a fixed value, where the frequency domain offset is specified by a protocol, and the time domain offset may be related to a cell ID or a terminal group ID to which the terminal belongs, for example, the offset in the time domain is calculated from the terminal ID or the terminal group ID, and the time domain offset may be an offset of an OFDM symbol, or an offset of a frame, or an offset of a subframe.

2. The time domain offset of the target transmission Resource of the TRS is a fixed value, where the time domain offset is specified by a protocol, the frequency domain offset may be related to a cell ID or a terminal group ID to which the terminal belongs, for example, the offset in the frequency domain is calculated from the terminal ID or the terminal group ID, and the frequency domain offset may be a subcarrier offset or a Physical Resource Block (PRB) offset.

3. The time domain offset and the frequency domain offset of the target transmission resource of the TRS are both related to a cell ID or a terminal group ID to which the terminal belongs, for example, the time domain offset and the frequency domain offset are both calculated by the terminal ID or the terminal group ID, where the time domain offset may be an offset of an OFDM symbol or an offset of a frame, and the frequency domain offset may be a subcarrier offset or a PRB offset.

Further, since the TRS can cover a large bandwidth, a plurality of physical channels for transmitting indication information can be transmitted within the TRS bandwidth in the frequency direction. The number of the OFDM symbol occupied by each physical channel, the subcarrier resource, and the position of the PRB occupied by the physical channel in the PRB occupied by the TRS may be predefined, configured by RRC signaling, or determined by calculation of a cell ID or a terminal group ID to which the terminal belongs.

Specifically, the TRS can cover a larger bandwidth, and multiple sets of physical channels for transmitting indication information may be transmitted in the TRS bandwidth in the frequency direction, where the physical channels may be continuous or discontinuous in the TRS bandwidth, and the bandwidths may be the same or different. For example, as shown in fig. 5, the physical channel 1 and the physical channel 2 are continuous, the physical channel 3 and the physical channel 4 are discontinuous, the bandwidths of the physical channel 1 and the physical channel 2 are the same, and the bandwidths of the physical channel 3 and the physical channel 4 are different.

The index information of the starting Slot/PRB of the physical channel may be predefined, or the network device configures the index information to the terminal through RRC signaling, and the configuration mode of the transmission resource of the physical channel may also refer to the mode one above. Specifically, the network device notifies the terminal of the time domain starting position of the physical channel for transmitting the indication information in the form of the slot/subframe advance offset value started by the PO/DRX On duration. After acquiring the time domain initial transmission position of the activation period of the PO and DRX periods of the paging opportunity and the target transmission resource and the lead offset value thereof, the terminal can determine the initial position of the time domain transmission resource of the physical channel.

Or, the configuration method of the transmission resources of the physical channel may also refer to the above-mentioned method two, that is, the frame/subframe/slot/PRB index of the physical channel may be related to the identity information of the terminal or the ID information of the cell where the terminal is located, and the transmission resources of different physical channels may be determined by calculating the identity information of the terminal or the ID of the cell where the terminal is located.

In the information transmission method of the embodiment of the invention, the network device sends the indication information carrying the indication field for indicating whether the terminal performs the detection of the physical downlink control channel PDCCH and whether performs at least one of the measurement and the report of the radio resource management RRM in the next DRX period to the terminal through the physical channel so as to indicate whether the terminal needs to perform the PDCCH detection and whether performs at least one of the RRM measurement and the report in the next DRX period, and the terminal determines whether to perform the PDCCH detection or the RRM measurement and the report according to the indication field in the indication information, so that the condition that the terminal performs the PDCCH detection in each DRX period or does not need the RRM measurement and does not need to perform the measurement report at the reporting time is avoided, and the signal processing power consumption of the terminal in the DRX state is reduced.

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

As shown in fig. 8, the information transmission method according to the embodiment of the present invention is applied to a terminal, and specifically includes the following steps:

step 81: transmission resources of a physical channel are determined.

The specific physical channel is mainly used for transmitting indication information, and specifically may be a special physical channel defined by a system, or a common physical channel scheduled by a network device for a terminal. Herein, determining the transmission resource of the physical channel refers to determining the time domain transmission resource and the frequency domain transmission resource occupied by the physical channel.

Step 82: and detecting the indication information sent by the network equipment through the transmission resource.

The indication information includes an indication field for indicating whether the terminal performs detection of a Physical Downlink Control Channel (PDCCH) in a next DRX period and at least one of measurement and reporting of Radio Resource Management (RRM). The next DRX cycle as referred to herein means a DRX cycle next to the DRX cycle in which the terminal detection indication information is located.

Further, the indication information includes at least two indication fields, where the at least two indication fields are used to respectively indicate whether different terminals or different terminal groups perform detection of a physical downlink control channel PDCCH in a next DRX cycle and at least one of measurement and reporting of radio resource management RRM. That is, the indication fields of a plurality of different terminals or a plurality of different terminal groups may be combined into one piece of indication information. The position of the indication field corresponding to the terminal or the terminal group in the indication information may be predefined, or may be dynamically configured through RRC signaling, or calculated according to at least one of the ID information of the terminal and the ID information of the terminal group (group) where the terminal is located.

Further, after step 82, the method further comprises: and decoding the indication information by a preset decoding mode. Wherein, the preset decoding mode comprises: and a decoding mode of at least one of a repetition code, an RM code, a Polar code, an LDPC code, a convolutional code and a Turbo code. For example, taking an example that the indication field includes one indication bit, where 0 represents sleep and 1 represents wake-up, if the bit stream obtained by decoding the indication information is 10010011, it indicates that 1 st, 4 th, 7 th, and 8 th terminals among the 8 terminals are wake-up; or to indicate that the terminals of groups 1, 4, 7 and 8 of the 8 terminals are awake.

Wherein, the step 81 specifically includes: determining the time domain transmission position of a physical channel according to the acquired time domain positions of the PO and DRX periods in the activation period; and determining the transmission resource of the physical downlink channel 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.

Specifically, the time domain starting position of the physical channel for transmitting the indication information may be configured to the terminal through signaling, where the configuration manner may be in the form of an advance offset value of a slot/subframe starting from the PO/DRX On duration. After the terminal acquires the time domain initial transmission positions of the activation periods of the PO and DRX periods and the transmission resources of the physical channel and the lead offset value thereof, the position of the time domain transmission resources of the physical channel can be determined.

Further, the step of determining the transmission resource of the physical channel according to the time domain transmission position 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 the transmission resources of the physical channel according to the time domain symbol number information and the frequency domain subcarrier number information.

The frequency domain subcarrier number information includes: a subcarrier offset. That is to say, the position of the starting OFDM symbol in the slot where the physical channel is located may be determined according to the terminal identity information and/or the ID information of the cell where the terminal is located.

In addition, step 81 can be further realized by the following steps: determining a time domain transmission position of a physical downlink channel, and time domain symbol number information and frequency domain subcarrier number information in the 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 transmission resources of the physical channel according to the time domain symbol number information and the frequency domain subcarrier number information.

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 frequency domain subcarrier numbering information comprising: a subcarrier offset. That is, the transmission resource of the physical channel for transmitting the indication information may be related to the identity information of the terminal or the ID information of the cell where the terminal is located, and the transmission resource of the physical channel for different terminals may be determined by the identity information of the terminal or the ID of the cell where the terminal is located.

Further step 82 specifically comprises the following steps: determining a target transmission resource of a tracking reference signal TRS; detecting TRS on target transmission resource and carrying out channel estimation to obtain channel estimation result; and detecting the indication information sent by the network equipment on the transmission resource according to the channel estimation result. That is, the terminal performs channel estimation based on the detected TRS, and estimates a delay and a frequency offset to compensate for a next received signal. Wherein the TRS can be used as a pilot signal of the physical channel for demodulating the indication information in the physical channel.

The step of determining a target transmission resource of the tracking reference signal TRS includes: determining a time domain transmission position of a tracking reference signal TRS according to the configured time domain positions of the paging opportunity PO and the activation period of the DRX period; and determining the target transmission resource of the TRS 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.

Specifically, the step of determining the target transmission resource of the TRS according to the time domain transmission position includes: determining time domain symbol number information and frequency domain subcarrier number information in a time domain transmission position of a tracking reference signal TRS 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 resource of the TRS according to the time domain symbol number information and the frequency domain subcarrier number information. 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 item of ID information of the terminal and ID information of a terminal group in which the terminal is located, wherein the frequency domain subcarrier number information comprises: a subcarrier offset.

Further alternatively, the step of determining the target transmission resource of the tracking reference signal TRS includes: determining a time domain transmission position, and time domain symbol number information and frequency domain subcarrier number information in the 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 resource of the TRS 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. The determination of the time domain transmission position of the TRS is similar to the determination of the time domain transmission position of the physical channel, and the specific determination may be implemented by referring to the manner of determining the time domain transmission position of the physical channel, so that details are not repeated herein.

Specifically, the offset of the target transmission resource of the TRS may be classified into three types: the frequency domain offset of the target transmission resource of the TRS is a fixed value, and the time domain offset can be related to a cell ID or a terminal group ID to which a terminal belongs; the time domain offset of the target transmission resource of the TRS is a fixed value, and the frequency domain offset can be related to a cell ID or a terminal group ID to which a terminal belongs; and the time-frequency domain offset of the target transmission resource of the TRS is related to the cell ID or the terminal group ID to which the terminal belongs.

Further, after the step of determining the target transmission resource of the tracking reference signal TRS and before the step of detecting the indication information sent by the network device on the transmission resource according to the channel estimation result, the method further includes: and detecting the TRS on the target transmission resource, and performing time-frequency fine synchronization by using the TRS. That is, the TRS can be used not only for channel estimation and as a pilot for a physical channel, but also for fine time-frequency synchronization.

Further, after step 82, the method further comprises: 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 field of the indication information.

Specifically, 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 field of the indication information includes: if the indication field of the indication information indicates that the PDCCH needs to be detected in the next DRX period, detecting the PDCCH; and if the indication field of the indication information indicates that RRM measurement and report are required, performing RRM measurement and report.

Specifically, at the DRX reception start time or the idle reception start time, the terminal receives a signal in advance on a predefined or scheduled time-frequency resource, performs channel estimation based on the received TRS, estimates a time delay and a frequency offset, and compensates for a next received signal. Then, the TRS is further used as indication information in a pilot signal demodulation physical channel to obtain a corresponding indication field, the terminal judges whether the indication field is specific to the terminal according to the ID of the terminal or the ID of a terminal group in which the terminal is located, if not, the terminal enters a sleep state, if so, the terminal enters an awake state according to an indication, and if the indication field is used for indicating that PDCCH and/or PDSCH detection is needed, the detection of the PDCCH and/or PDSCH is carried out in the next DRX period.

Or, at the DRX reception start time or the idle reception start time, the terminal receives in advance on a predefined or scheduled time-frequency resource, performs channel estimation based on the received TRS, estimates a time delay and a frequency offset, and compensates for a next received signal. Then, the TRS is further used as the indication information in the pilot signal demodulation physical channel to obtain a corresponding indication field, the terminal judges whether the indication field is specific to the terminal according to the ID of the terminal or the ID of the terminal group, and if not, the terminal enters a sleep state. If the indication field is detected to indicate the terminal to perform the RRM measurement and perform the measurement report at the next RRM report time or at a predefined or configured time, the terminal may determine that the RRM measurement and report are required according to the indication field.

In the information transmission method of the embodiment of the invention, the terminal receives the indication information which is sent by the network equipment through the physical channel and carries the indication field used for indicating whether the terminal performs the detection of the physical downlink control channel PDCCH in the next DRX period or not and whether at least one of the measurement and the report of the radio resource management RRM is performed or not, so as to determine whether to perform the PDCCH detection or the RRM measurement and the report, thereby avoiding the terminal performing the PDCCH detection in each DRX period or not requiring the RRM measurement and not requiring the measurement and the report at the reporting time, and reducing the signal processing power consumption of the terminal in the DRX state.
