Description

Transmission method, system, network terminal and terminal device for wireless communication reference signal

This application claims the priority of the Chinese patent application filed on August 28, 2020 with the application number CN202010889149.5 and the application title "Method, System, Network Terminal and Terminal Equipment for Wireless Communication Reference Signal Transmission", The entire contents of which are incorporated herein by reference.

technical field

The present invention relates to the technical field of electronic communication, and in particular, to a method, system, network terminal and terminal device for transmitting a wireless communication reference signal.

Background technique

In the idle/inactive state, the terminal equipment (UE) frequently wakes up to perform related activities (ie, time-frequency synchronization, AGC (automatic gain control) adjustment, and measurement of the serving cell, etc.) will increase the number of terminal equipment Therefore, reducing the number of times that the terminal device wakes up in the idle/inactive state is a topic currently being discussed by 3GPP (3rd Generation Partnership Project).

At present, 3GPP's solution is to introduce an additional reference signal (additional RS, ARS) in the idle/inactive state to reduce the number of times the terminal equipment wakes up, that is, through the additional reference signal, the terminal equipment can The measurement of the serving cell and the monitoring of paging messages are centralized, thereby reducing the number of times the terminal equipment wakes up.

Currently, there are two transmission methods for additional reference signals in the prior art. One is to associate with the SSB (SS/PBCH (Physical Broadcast Channel) Block, synchronization signal and PBCH block) location, that is, to send the additional reference signal before and after the SSB transmission location. For the reference signal, the other is associated with the PO (Paging occasion, paging moment) location, that is, an additional reference signal is sent in front of the PO (and close to the PO).

Currently, the two additional reference signal transmission modes have different energy saving gains in different scenarios. However, considering the resource overhead, it is obviously unacceptable to configure additional reference signals before PO and before and after SSB.

Therefore, there is an urgent need for a new additional reference signal transmission mechanism that can fully utilize the advantages of the two additional reference signal transmission modes.

detailed description

The present invention is further described below by means of examples, but the present invention is not limited to the scope of the described examples.

Example 1

In order to overcome the above-mentioned defects at present, this embodiment provides a method for transmitting a wireless communication reference signal, the transmission method is applied to a terminal device, and the transmission method includes: the terminal device obtains indication information of network transmission; the The terminal device determines, according to the indication information, whether it needs to monitor the PO in at least one subsequent paging cycle, and if so, determines the location of the additional reference signal through the correlation between the additional reference signal and the PO position in the at least one paging cycle. Resource location, if not, determine the resource location of the additional reference signal through the association relationship between the additional reference signal and the SSB location within the at least one paging cycle.

This embodiment also provides a method for transmitting a wireless communication reference signal. The transmission method is applied to a network end device, and the transmission method includes: the network end device generates indication information for network transmission and sends the indication information to a The above terminal device, so that the terminal device determines whether it needs to monitor the PO in at least one subsequent paging cycle according to the indication information, and if so, in the at least one paging cycle, through the additional reference signal and the PO position The resource position of the additional reference signal is determined by the association relationship, and if not, the resource position of the additional reference signal is determined by the association relationship between the additional reference signal and the SSB position in the at least one paging cycle.

Preferably, in this embodiment, the terminal device is an NR device, and the additional reference signal is TRS or CSI-RS, but it is not limited to this, and can be selected and adjusted according to actual needs.

In this embodiment, a stable and effective transmission mechanism for additional reference signals can be provided, and the terminal equipment needs to monitor PO in at least one subsequent paging cycle and does not need to monitor PO in at least one subsequent paging cycle. , respectively determine the transmission mode, thereby further effectively saving the power consumption of the terminal device on the basis of saving the additional reference signal resource overhead, thereby improving the user experience.

Example 2

On the basis of Embodiment 1, as shown in FIG. 1 , the method for transmitting a wireless communication reference signal provided by this embodiment includes the following steps:

Step 101: The network end device sends the generated indication information of network transmission to the terminal device.

In this step, the network end device generates indication information for indicating whether the terminal device needs to monitor the subsequent PO, and sends the indication information to the terminal device.

Step 102: The terminal device acquires the indication information of network transmission from the network terminal device.

In this step, the terminal device obtains the indication information from the network by receiving a wake-up signal or Paging DCI.

In this embodiment, in order to reduce the energy consumption of the terminal device monitoring the PO in the idle/inactive state, one method is to send a wake-up signal before the PO to indicate whether the terminal device needs to monitor the following POs or whether it needs to monitor multiple subsequent POs. Another method is that the terminal device determines whether it needs to monitor multiple subsequent POs by monitoring the PO, that is, the network carries indication information through the paging DCI to indicate whether the terminal device needs to monitor multiple subsequent POs.

About Paging

Specifically, the functions of the Paging message include: (1) sending a call request to the terminal equipment in the RRC (Radio Resource Control)_IDLE state; (2) notifying the terminal equipment in the RRC_IDLE/INACTIVE and RRC_CONNECTED (connected) states that the system information occurs (3) Earthquake and tsunami notification, instructing the radio resource control to start receiving ETWS (earthquake and tsunami warning system) primary (primary) notification and/or ETWS secondary (secondary) notification; (4) instructing the terminal device to start receiving CMAS (commercial Mobile Alerting System) notification.

If a terminal device is paged or the system information is updated, or an earthquake or tsunami occurs, the base station will first send a wake-up signal. After the terminal device detects the wake-up signal, it will monitor the paging PDCCH (Physical Downlink Control Channel) and receive the paging message. , otherwise the terminal device remains in the sleep state to save power.

Referring to Figure 2, in NR, a terminal device may use discontinuous reception (DRX) in RRC_IDLE and RRC_INACTIVE states in order to reduce power consumption. The terminal equipment monitors the PO periodically (the period is the DRX period).

In addition, before the terminal device receives Paging, it needs to use a reference signal (eg, SSB) to complete time-frequency synchronization and AGC adjustment.

About Wakeup Signal (WUS)

With the recent rise of smart phones, the functions of mobile phones are becoming more and more powerful, and the power consumption of terminal devices directly affects user experience. Therefore, users have an increasingly strong demand for terminal energy conservation.

The power consumption of the terminal equipment in the idle state is mainly used for measuring, performing cell reselection, and monitoring the PDCCH for paging, wherein the power consumption for monitoring the PDCCH for paging accounts for most of the power consumption. LTE (Long Term Evolution) puts forward higher requirements for the power consumption of MTC (Machine Type Communication) terminals and NB-IoT (Internet of Things technology system based on mobile communication network) terminals, and introduces a new wake-up signal to indicate the terminal. Whether to perform PDCCH monitoring. The idle state terminal mainly monitors the paging PDCCH, and the connected state terminal needs to monitor the PDCCH scheduled by the uplink and downlink data. In view of time reasons, LTE focuses on the idle state terminal to monitor the paging PDCCH when designing the wake-up signal.

Referring to Figure 3, in the DRX scenario, each PO is associated with a wake-up signal WUS, the position of the wake-up signal is a fixed gap (fixed gap) before the PO starts, and the starting position of the gap is the configured wake-up signal The end position of the maximum period (WUS max duration), the actual transmitted wake-up signal is not of a fixed length, starting from the starting position of the configured maximum period of the wake-up signal, taking 1 subframe as the basic unit, and repeating or extending into multiple subframes for transmission , the maximum duration of the configured wake-up signal cannot be exceeded, and the terminal device needs to monitor the actually transmitted wake-up signal according to the power of 2 subframes.

In addition, as shown in FIG. 4 , in the eDRX (Extended idle mode DRX, enhanced discontinuous reception) scenario, in each eDRX cycle, there is a paging time window PTW (Paging Time Window), the terminal in the PTW according to The DRX cycle (DRX cycle time is short, it can be considered that the terminal does not sleep and is always reachable) monitors the paging channel in order to receive downlink data, and the terminal is in a dormant state for the rest of the time. In the eDRX scenario, a wake-up signal can be associated with multiple POs (assuming m POs), that is, once the terminal device receives the wake-up signal indication, it needs to monitor the subsequent m POs.

About the activity of terminal equipment in idle/inactive state

In the idle/inactive state, for the measurement of the serving cell, the terminal device will basically perform the measurement of the serving cell in each DRX cycle. The purpose of the measurement is one for cell reselection and the other for monitoring PO before Complete time-frequency synchronization and AGC adjustment.

In the idle/inactive state, before the terminal device receives Paging in each DRX cycle, it needs to use 1 to 2 synchronization signal blocks (SS/PBCH block, SSB) to complete time-frequency synchronization, AGC adjustment and RRM ( radio resource management) measurements.

When the channel quality of the terminal equipment is relatively good (for example, the terminal equipment is in a non-edge area of the cell), the terminal equipment generally only needs to use one synchronization signal block to complete time-frequency synchronization, AGC adjustment and RRM measurement for the serving cell.

When the channel quality of the terminal equipment is relatively poor (for example, the terminal equipment is at the edge of the cell) or wakes up from a deep sleep state (that is, the DRX cycle is relatively large), the terminal equipment generally needs to use 2 synchronization signal blocks to complete the time-frequency synchronization. AGC adjustment and RRM measurement for serving cell.

Since the SSB is sent periodically (the period size is at the cell level, that is, the SSB transmission period of a cell is the same), each PO cannot be guaranteed (the period of the PO is at the terminal device level, and each terminal device has its own specific PO Period) are close to a certain SSB. If the distance between the SSB and the PO is large, the terminal device needs to wake up multiple times in order to receive paging (1 to 2 times for synchronization/AGC adjustment/serving cell RRM measurement, once for monitoring PO), If the SSB is close to the PO, the terminal device only needs to wake up 1 to 2 times to complete the time-frequency synchronization, AGC adjustment, measurement of the serving cell and reception of paging.

For example, referring to Figure 5a, when the channel environment of the terminal device is good, the terminal device generally needs to wake up twice; referring to Figure 5b, when the channel environment of the terminal device is poor or the DRX cycle is very large, The terminal device generally needs to wake up 3 times.

About additional reference signals

In this embodiment, the transmission modes of the additional reference signal (ie, TRS/CSI-RS) are generally divided into two types, one is associated with the SSB position, that is, the additional reference signal is sent before and after the SSB transmission position, and the other is An additional reference signal is sent before (and close to) the PO.

An example is given below in conjunction with the accompanying drawings.

Mode 1: Send an additional reference signal (ARS for short) in front of the PO (and close to the PO)

Referring to Fig. 6a, a terminal device with a better signal environment generally needs to wake up (wake up) once.

Referring to Fig. 6b, a terminal device with poor signal environment generally needs to wake up twice.

Method 2: Send additional reference signals before and after the SSB location (and close to the PO)

Referring to Fig. 6c, a terminal device with a better signal environment generally needs to wake up twice.

Referring to Fig. 6d, a terminal device with poor signal environment generally needs to wake up twice.

About NR

RRM measurement is one of the most power consuming operations of terminal equipment, which is used for the mobility management of terminal equipment. For RRM measurement, the power consumption is proportional to the measurement frequency and the number of measurement objects, including the number of measured SSBs, the number of cells, and the number of frequencies. Under certain conditions, some RRM measurements of terminal equipment are not necessary, but consume a lot of terminal equipment power. For example, low-mobility terminal equipment does not have to measure as frequently as high-mobility terminal equipment, reducing the frequency of RRM measurement of terminal equipment. It is also a direct and effective method to reduce the power consumption of RRM measurement.

The RRM measurement requirement of the idle terminal equipment is that the terminal equipment performs RRM measurement (that is, RSRP (Reference Signal Received Power)/RSRQ (Reference Signal Received Quality) measurement) and cell reselection evaluation for the serving cell at least once in each DRX cycle.

Under certain conditions, such frequent serving cell measurement activity is unnecessary and consumes a lot of terminal device power, eg, low mobility terminal devices do not have to measure as frequently as high mobility terminal devices.

In order to reduce the energy consumption caused by the measurement activities of the terminal equipment, when the terminal equipment meets certain conditions (that is, the measurement relaxation condition is satisfied), the terminal equipment can perform RRM measurement on the serving cell every n DRX cycles (that is, RSRP/RSRQ measurement) and perform cell reselection evaluation, where the value of n is configured by the network to the terminal device.

Step 103: The terminal device determines, according to the indication information, whether it needs to monitor the subsequent PO in at least one subsequent paging cycle, if so, go to step 104, and if not, go to step 105.

In this embodiment, the situation in which the terminal device needs to monitor PO in at least one subsequent paging cycle is different from the situation in which the terminal device does not need to monitor PO in at least one subsequent paging cycle, and the transmission position of the additional reference signal needs to be different. This embodiment effectively utilizes this to propose a reference signal transmission mechanism.

Step 104: Determine the resource location of the additional reference signal by using the PO location and its corresponding first offset in at least one subsequent paging cycle.

In this step, referring to FIG. 7a, in the subsequent at least one paging cycle, the resource position of the additional reference signal is determined by the PO position and the corresponding first offset (offset1).

In this embodiment, the first offset is the offset between the additional reference signal and the PO that is pre-obtained by the terminal device through a high-level instruction of the network.

Preferably, in this embodiment, the high-level instruction includes a system broadcast message or RRC.

In this step, when the wake-up signal or Paging DCI indicates that the terminal device needs to monitor one or more following POs, for the terminal device with a better channel environment, it may still need to wake up twice to complete the AGC/time-frequency synchronization /RRM and PO monitoring. If the additional reference signal is close to the PO at this time, the terminal device with a better channel environment only needs to wake up once.

Preferably, in this step, in response to the time domain distance between the SSB that is closest to the PO and the PO before the PO is greater than or equal to a preset threshold, the PO position and its corresponding first offset are determined. Resource location of additional reference signals.

That is, when the time domain distance between the closest SSB position before the PO and the PO is less than the preset threshold, the network will not send the additional reference signal before the PO, and the terminal device does not need the additional reference signal (the terminal device does not need the additional reference signal The signal does not affect the configuration and transmission of the additional reference signal), and the terminal device also believes that in this case, the resource location of the additional reference signal cannot be determined through the first offset, wherein the preset threshold can be configured by high-level parameters (for example, by The size of the threshold is notified to the terminal device by means of system message broadcasting, and the unit of the threshold may be ms or time slot), or corresponding settings may be made according to actual needs.

Step 105: Determine the resource location of the additional reference signal by using the SSB location and its corresponding second offset in at least one subsequent paging cycle.

In this step, referring to FIG. 7b, in the subsequent at least one paging cycle, the resource location of the additional reference signal is determined by the SSB location and the corresponding second offset (offset2).

In this embodiment, the second offset is an offset between an additional reference signal pre-obtained by the terminal device through a high-level instruction and an SSB located before the PO and closest to the PO.

In this step, when the wake-up signal or the Paging DCI indicates that the terminal device does not need to monitor the following one or more POs, for the terminal device with poor channel environment, it may still need to wake up in the following one or more DRXs Complete AGC/time-frequency synchronization/RRM twice. If the additional reference signal is close to the SSB at this time, the terminal equipment with poor channel environment only needs to wake up once to complete AGC/time-frequency synchronization/RRM, and the terminal equipment with good channel environment only needs to wake up once.

In this embodiment, the terminal device can determine by receiving the wake-up signal or paging DCI whether there is additional reference signal transmission in the subsequent X consecutive paging cycles, that is, the network indicates to the terminal device whether the subsequent X paging cycles are through the wake-up signal or paging DCI. There is additional reference signal transmission (it is assumed that the indication is an additional reference signal trigger indication, 1 bit). The terminal device first determines whether there is additional reference signal transmission in the subsequent X Paging cycles according to the wake-up signal or the additional reference signal trigger indication in the paging DCI, and if so, determines the additional reference signal resource according to the above transmission method. Location.

The method for transmitting reference signals in wireless communication provided by this embodiment can provide a stable and effective transmission mechanism for additional reference signals. The first offset is used to determine the resource location of the additional reference signal. When the terminal device does not need to monitor the PO in at least one subsequent paging cycle, the additional reference is determined by the location of the SSB before the PO and closest to the PO and the corresponding second offset. The resource location of the signal can further effectively save the power consumption of the terminal device on the basis of saving the additional reference signal resource overhead, thereby improving the user experience.

Example 3

On the basis of selectively referring to the content of Embodiment 2, as shown in FIG. 8 , the method for transmitting a wireless communication reference signal provided by this embodiment includes the following steps:

Step 101': The network end device sends the generated indication information of network transmission and the first transmission parameter configuration and the second transmission parameter configuration of the additional reference signal to the terminal device.

In this step, the network end device generates indication information for indicating whether the terminal device needs to monitor the PO in at least one subsequent paging cycle (in this embodiment, it also represents which set of transmission parameter configuration to instruct the terminal device to select) and additional reference The first transmission parameter configuration and the second transmission parameter configuration of the signal, and the indication information and the first transmission parameter configuration and the second transmission parameter configuration of the additional reference signal are sent to the terminal device.

In this embodiment, the position of the corresponding additional reference signal under the first transmission parameter configuration is associated with the PO position, and the position of the corresponding additional reference signal under the second transmission parameter configuration is associated with the SSB position.

In this embodiment, the transmission parameter configuration includes the start position and period of the additional reference signal.

Specifically, the network configures two sets of transmission parameters of the additional reference signal (TRS/CSI-RS) for the terminal device (including the starting position, period, etc. of the additional reference signal), and one set of transmission parameters of the additional reference signal (that is, the first Transmission parameter configuration) is aligned with PO, that is, under this set of transmission parameter configuration, the additional reference signal is before PO and close to PO; the transmission parameter configuration of another set of additional reference signals (ie the second transmission parameter configuration) is aligned SSB, that is, under the configuration of the additional reference signal transmission parameters, the time domain position of the additional reference signal is close to the SSB before the PO and closest to the PO.

Step 102', the terminal device obtains the indication information of network transmission and the first transmission parameter configuration and the second transmission parameter configuration from the network end device.

In this step, the terminal device obtains the indication information of the network transmission from the network by receiving the wake-up signal or Paging DCI, and also obtains the first transmission parameter configuration and the second transmission parameter configuration through high-level instructions.

Step 103', the terminal device judges whether it needs to monitor the subsequent PO in at least one subsequent paging cycle according to the indication information, if yes, go to step 104', if not, go to step 105'.

In this step, a first transmission parameter configuration is selected, and the resource location of the additional reference signal is determined according to the first transmission parameter configuration in the subsequent at least one paging cycle.

When the terminal device determines by receiving the wake-up signal or Paging DCI that it needs to monitor the subsequent X consecutive POs, the terminal device determines the resource location of the additional reference signal by configuring the first transmission parameter of the additional reference signal.

Preferably, in response to the time domain distance between the SSB closest to the PO before the PO and the PO is greater than or equal to a preset threshold, the resource location of the additional reference signal is determined according to the first transmission parameter configuration .

That is, when the time domain distance between the closest SSB position before the PO and the PO is less than the preset threshold, the terminal device considers that the resource position of the additional reference signal cannot be determined through the first transmission parameter configuration of the additional reference signal in this case, The threshold can be configured by high-level parameters (for example, the terminal device is notified of the threshold size by means of system message broadcasting, and the threshold unit can be ms or time slot), or can be set according to actual needs.

Step 105': Select the second transmission parameter configuration, and determine the resource location of the additional reference signal according to the second transmission parameter configuration in at least one subsequent paging cycle.

In this step, a second transmission parameter configuration is selected, and the resource location of the additional reference signal is determined according to the second transmission parameter configuration in the subsequent at least one paging cycle.

When the terminal device determines by receiving the wake-up signal or paging DCI that it does not need to monitor the subsequent X consecutive POs, the terminal device determines the resource location of the additional reference signal by configuring the second transmission parameter of the additional reference signal.

In this embodiment, the terminal device can determine whether there are additional reference signal transmissions in successive X consecutive paging cycles by receiving a wake-up signal or paging DCI, that is, the network instructs the terminal device to follow X paging cycles through the wake-up signal or paging DCI Whether there is additional reference signal transmission (it is assumed that the indication is an additional reference signal trigger indication, 1 bit). The terminal device first determines whether there is additional reference signal transmission in the subsequent X paging cycles according to the wake-up signal or the additional reference signal trigger indication in the paging DCI, and if so, determines which set of additional reference signals to use according to the above transmission method. The transmission parameter configuration is used to determine the resource location of the additional reference signal.

The method for transmitting reference signals in wireless communication provided by this embodiment can provide a stable and effective transmission mechanism for additional reference signals. When a terminal device needs to monitor PO in at least one subsequent paging cycle, it can be determined by configuring a first transmission parameter. The resource location of the additional reference signal, when the terminal device does not need to monitor the PO in at least one subsequent paging cycle, the resource location of the additional reference signal is determined through the second transmission parameter configuration, so as to save the additional reference signal resource overhead on the basis of, The power consumption of the terminal device is further effectively saved, thereby improving the user experience.
