Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, without having to use To describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in a sequence other than the content illustrated or described herein. In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those clearly listed. Those steps or units may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment. The term "and/or" refers to either or both.

The embodiments of the present application can be applied to the beamforming mode network framework diagram shown in FIG. 1, and the network framework diagram includes:

Access the network side device 101, the terminal side device 102, and the antenna ports 103 to 106.

It is understandable that the number of terminal-side devices in actual applications is not limited.

The number of antenna ports can be no less than two, and the specific number is not limited. The embodiment of this application uses four as an example for illustration. Among these antenna ports, there are at least two antenna ports quasi co-location (QCL). ) The space receiving parameters are different.

It should be noted that in practical applications, an antenna port can be a logical concept, which can be physically mapped to a physical antenna panel or a physical antenna unit, or it can be a port formed by aggregating multiple antenna panels or antenna units. Among them, the spatial receiving parameter may be the number of physical antenna units used, the phase adjusted by each physical antenna unit, the gain of the power amplifier, the antenna tilt angle and other parameters.

It should be noted that an antenna port is defined as having the characteristic that on the same antenna port, the channel for transmitting a certain signal can be inferred from the channel for transmitting another signal. Therefore, according to the channel of the reference signal transmitted on certain time domain symbols or certain frequency domain resources on a certain antenna port, other time domain symbols or channels on other frequency domain resources for data transmission on this antenna port can be inferred. The channel status (or called the channel status of this antenna port). Further, in order for the terminal-side device to receive data correctly, generally speaking, multiple antenna ports of the same network-side device have a QCL relationship. Among them, the large-scale characteristics of the channel that transmits a certain signal on one antenna port ( large-scale properties), when it can be inferred from the channel that transmits a certain signal on another antenna port, the two antenna ports are defined as having a QCL relationship. The large-scale characteristics here include at least one of Doppler frequency shift, Doppler spread, average delay, delay spread, and spatial reception characteristics. The detailed content of the large-scale characteristics can refer to the prior art. That is to say, in the process of channel estimation based on the reference signal transmitted by a certain antenna port to obtain the channel state on this antenna port, the terminal-side device can be based on the magnitude of the reference signal transmitted on other antenna ports with a QCL relationship. The scale characteristic infers the large-scale characteristic of the reference signal transmitted on this antenna port in order to determine the channel state on this antenna port.

The terminal-side equipment includes user equipment (UE), or a chip system for implementing the function of the UE, and the embodiment of the present application takes the UE as an example for description.

The access network side device 101 sends downlink control information to the UE 102 through antenna ports 103 to 106. The UE may need to adjust the receiving antenna panel or use different receiving antenna ports to receive the downlink control information sent through different antenna ports. The relationship between the different antenna ports of the equipment on the access network side can be represented by different QCL quasi co-locations in the transmission configuration indicator state (TCI-state). QCL includes multiple categories. Each type of QCL parameter indicates the identifier of a reference signal. The reference signal is also called a source reference signal (source reference signal, Source RS), which means that the signal or channel configured by the TCI-state has the same reference signal as the source reference signal. The same large-scale properties (large-scale properties) channel parameters, where the D type QCL (QCL-typeD) indicates the spatial reception parameter (spatial RX parameter), indicating that the signal configured by the TCI-state or the channel and source reference signal can be used When receiving the same spatial receiving parameter, the UE can use the same spatial receiving parameter to correctly receive the information sent by the same or different antenna ports corresponding to the same spatial receiving parameter.

The third generation partnership project (3GPP) standards organization is formulating protocol standards for the fifth generation cellular mobile communication system. Compared with the LTE system, the NR system supports a larger transmission bandwidth, more transceiver antenna arrays, a higher transmission rate and a more flexible and smaller-granularity scheduling mechanism. The above-mentioned characteristics of the NR system provide more scope of application. , But at the same time greatly increases the power consumption burden of the UE.

In order to reduce the power consumption of the UE, 3GPP introduced the power saving research topic in the NR rel-16 (new radio release 16) version. The purpose is to study how the UE can be in various states (including connected state, idle state). State, and inactive state, etc.) possible power reduction schemes. Among them, how to save UE power consumption in the connected state is a research focus.

3GPP has designed a discontinuous reception (DRX) mechanism to reduce the UE power consumption of the UE in the connected state. Its main features are shown in Figure 2 as a schematic diagram of the DRX cycle:

The basic time unit in the DRX state is a DRX cycle, and the duration of a DRX cycle is called a DRX cycle 200. A DRX cycle can also become a DRX cycle 200, including a sleep time 201 (sleep, also known as discontinuous reception off, DRX_OFF) and a wake-up time 202 (on duration, also known as discontinuous reception on, DRX_ON, also known as DRX_ON) active time).

When the DRX cycle 200 is in the sleep time 201, the UE in the sleep mode can completely turn off the communication device (such as: radio frequency transceiver, baseband processor, etc.) to reduce power consumption. When the DRX cycle 200 is at the wake-up time 202, the UE in wake-up mode monitors the downlink control channel (physical downlink control channel, PDCCH), and starts an inactive timer (inactive timer), once the downlink control channel is received Control information, the UE will restart the inactivity timer to calculate the timing. If the inactivity timer expires, the UE returns to the sleep mode.

Under normal circumstances, the UE does not wake up at the beginning of the wake-up time 202, but will wake up at a period of time before the wake-up time 202 starts, such as several time slots. A time slot can include 12 or 14 symbols. After waking up, it will receive the downlink reference signal and perform time-frequency offset synchronization and other operations first to prevent the UE's clock and working frequency from deviating from the base station clock and frequency domain due to the long-term sleep mode. At the same time, the UE can also try to update the system message first (Master Information Block MIB or System Information Block SIB).

The wake-up signal is a control signal introduced by the NR system to reduce UE power consumption, and is mainly used in the connected DRX mechanism.

Under DRX, the UE is generally in the sleep time, but the UE needs to wake up every time a period of time has elapsed and enter the wake-up time to receive the downlink control information sent by the downlink control channel. In the actual system, the access network side device does not send downlink control information to the UE every time it wakes up. Therefore, the UE trying to receive downlink control information during most of the wake-up time is an invalid operation, and the invalid operation will increase. UE power consumption.

For this reason, the NR system introduces a wake-up signal. If the access network side device will send a schedule to the UE in a certain DRX cycle, the access network side device will send the wake-up signal within a period of time before the wake-up time arrives. The UE will try to receive the wake-up signal within a period of time before the wake-up time arrives. If it receives the wake-up signal, the UE confirms that there is scheduling in the next wake-up time, and the UE tries to receive the downlink control information for scheduling during the wake-up time, and vice versa. If the UE does not receive the wake-up signal, the UE considers that there is no scheduling in the next wake-up time, and the UE does not try to receive downlink control information within the wake-up time, that is, the UE can continue to sleep.

Since the probability of sending scheduling to the UE in DRX is generally low, the wake-up signal can greatly save the power consumption of the UE.

The sending timing of the wake-up signal is sent in a pre-defined search space set, and the search space set has a pre-configured bandwidth and sending period on the time-frequency resource. The search space set is configured in the control resource set (CORESET). Each control resource set has its corresponding identity (ID). The control resource set defines the frequency resources occupied by the search space set. In the domain, the transmission cycle time of the search space set can range from 1 time slot to 2560 time slots. In each cycle, there can be one or several consecutive time slots to send the wake-up signal. Please refer to Figure 3:

The embodiment of the present application takes a search space set period 300 as an example for description. The search space set period 300 includes time slots 301 to 304, and the number of time slots included in a search space set period 300 is not limited.

In each time slot in which the wake-up signal is sent, the access network side device can also configure the specific location where the wake-up signal is sent in each time slot in which the wake-up signal is sent. The sending time of the wake-up signal may be represented by 1 to 3 symbols in a time slot, such as 3051 to 3053, and these symbols may be referred to as a monitoring occasion 305 to 306. According to the configured search space set period 300, the wake-up signal appears in the time slot position of each period. According to Figure 3, the wake-up signal appears in the time slot 302 and 303, and monitors the appearance position of the timing 305 to 306 in each time slot. As well as the number of symbols included in the monitoring timing, according to FIG. 3, the number of symbols included in the monitoring timing 305 and the monitoring timing 306 are both 3, and the monitoring timing is determined in one cycle.

The following describes the information transmission methods in the embodiments of the present application with reference to the schematic diagrams of FIG. 1 to FIG. 3.

1. Please refer to Fig. 4, an embodiment of the information transmission method in the embodiment of the present application includes:

401. The access network side device sends a wake-up signal to the terminal side device;

The terminal-side equipment includes user equipment UE, or a chip system for implementing UE functions, and this embodiment takes UE as an example for description. The access network side device sends wake-up signals to the UE through two or more antenna ports, and at least two of these antenna ports have different QCL space reception parameters. When the UE is working in FR2, the wake-up signal can be beam-forming. Shaped method to send. The number of control resource sets includes the following two categories, which are described below:

(1) Configure two or more control resource sets to send wake-up signals, please refer to Figure 5:

Since in the NR protocol, TCI-state is configured on the control resource sets 501 to 503, the access network side device can configure multiple control resource sets to send wake-up signals. This embodiment takes three control resource sets 501 to 503 as an example. Note, it is understandable that in this configuration mode, the number of control resource sets is not less than two and the specific number is not limited. Each control resource set 501 or 502 or 503 configures the QCL in the TCI-state The space receiving parameters are not the same. As long as the UE detects the wake-up signal in the search space set of any control resource set 501 or 502 or 503, that is, as long as the UE detects the wake-up signal on any antenna port, the UE detects the downlink control information in the next wake-up time .

(2) Configure a control resource set to send wake-up signals, please refer to Figure 6:

The access network side device only configures one control resource set 600 for sending wake-up signals, but different monitoring timings 601 to 606 of the search space set in the control resource set 600 can be configured with different TCI-states. This embodiment takes 6 monitoring occasions 601 to 606 as an example for description. As shown in Fig. 6, the search space set used for wake-up signal transmission in the control resource set 600 is configured with 6 monitoring occasions in one cycle, among which, the monitoring time 601 And 602 use the TCI-state configuration of the first control resource subset, monitoring

timings

603 and 604 use the TCI-state configuration of the second control resource subset, and monitoring timings 605 and 606 use the TCI-state configuration of the third control resource subset. State configuration, the first control resource subset, the second control resource subset, and the third control resource subset belong to some resources in the control resource set 600, that is, the six monitoring occasions 601 to 606 are configured in one control resource set , But TCI-state borrows different configuration resources of the control resource set. As long as the UE detects a wake-up signal in any one of the monitoring occasions 601 to 606, that is, detects a wake-up signal on any antenna port, the UE detects the downlink control information in the next wake-up time.

402. The terminal side device sends instruction information to the access network side device.

After the access network side device sends a wake-up signal to the terminal side device, such as the UE, the UE sends indication information to the access network side device. The indication information indicates the QCL space reception parameters used by the UE to detect the wake-up signal. And the terminal-side device adopts beamforming mode to transmit data, and different QCL space receiving parameters can indicate different beams.

Since the UE may detect the wake-up signal on the antenna ports corresponding to multiple QCL space receiving parameters, the UE can send the space receiving parameter configured for the wake-up signal with the best detected signal quality to the terminal side device, and the signal quality can be a reference for receiving the wake-up signal Signal receiving power (reference signal receiving power, RSRP), or reference signal receiving quality (reference signal receiving quality, RSRQ), the specific signal quality is not limited here.

The indication information may also include multiple QCL space receiving parameters, that is, QCL space receiving parameters of two or more wake-up signals. If the indication information includes multiple QCL space receiving parameters, the multiple QCL space receiving parameters can be detected according to the UE. The signal quality of the wake-up signal is sorted and sent to the access network side device. This embodiment does not limit the number of QCL space receiving parameters included in the indication information. If the indication information includes multiple QCL space receiving parameters, the ordering manner of the multiple QCL space receiving parameters is not limited.

The indication information can be TCI-state identification (identity, ID) information, or it can be the identification information of the source reference signal corresponding to the QCL space receiving parameter parameter in the TCI-state indicated by the TCI-state identification, if the source reference signal is a synchronization signal Block (synchronization signal block, SSB), the identification information may be the SSB index (index), if the source reference signal is a non-zero power channel state information reference signal (non-zero power channel state information reference signal, NZP-CSI-RS), Then the identification information can be NZP-CSI-RS ID. If the access network side device configures two or more control resource sets to send wake-up signals, the indication information can be the ID information of each control resource set. When a control resource set is configured to send a wake-up signal, the indication information may be the index number of the monitoring opportunity, and the expression form of the specific beam information is not limited here.

The UE can send indication information to the access network side device through the physical uplink control channel (PUCCH). The time-frequency resources occupied by the PUCCH are passed through high-level signaling, such as radio resource control (radio resource control) sent by configuring the wake-up signal. , RRC) signaling is pre-configured to the UE. The UE can also send indication information to the access network side device through the physical uplink shared channel (PUSCH). The PUSCH is generally used to send uplink data, and the access network side device can The PUSCH resource corresponding to the wake-up signal is pre-configured for the UE to send indication information, or if the UE needs to send uplink data after entering the wake-up mode, the indication information can be piggybacked into the PUSCH data, and the specific reporting channel is not limited here.

403. The access network side device determines the transmitting antenna port;

The device on the access network side determines the transmitting antenna port according to the instruction information, and the instruction information indicates the quasi-co-site QCL space receiving parameter used by the UE to detect the wake-up signal, that is, the device on the access network side can determine the antenna port using the QCL space receiving parameter is Transmit antenna port.

404. The access network side device sends downlink control information to the terminal side device.

The access network side device sends downlink control information to the UE through the transmit antenna port. It can be understood that if the access network side device determines a transmit antenna port, the access network side device sends downlink control information to the UE through the antenna port If the access network side device determines multiple transmit antenna ports, the access network side device can send downlink control information to the UE through one or more of the transmit antenna ports.

2. Refer to Fig. 7, another embodiment of the information transmission method in the embodiment of the present application includes:

701. The access network side device sends a wake-up signal to the terminal side device.

702. The terminal-side device determines whether there is channel state information CSI measurement and/or CSI measurement result report within a preset time period, if not, execute step 705, if yes, execute step 703;

The terminal-side equipment includes user equipment UE, or a chip system for implementing UE functions, and this embodiment takes UE as an example for description.

If the UE receives the channel state information (CSI) measurement signal configured by the access network side device before receiving the wake-up signal, the UE can perform CSI measurement based on the measurement signal, such as the access network side device pre-configured Periodic or semi-persistent (semi-persistent) CSI measurement, or the aperiodic CSI measurement triggered by a wake-up signal or other downlink control signal by the access network side device, the measurement signal can be any type based on NZP- CSI-RS or SSB signal. The preset time period for the UE to perform CSI measurement may be the period from when the access network side device sends a wake-up signal to the UE until the UE enters the wake-up time. In actual operation, the preset time period may also include the access network side device sending the UE to the UE. The wake-up signal is sent to the time period when the UE enters the vicinity of the wake-up time, which is not specifically limited here.

The UE generates a CSI measurement result through CSI measurement, and the measurement result may include information such as signal quality and index of the measured signal. The signal quality may be RSRP or RSRQ of the received measurement signal, or other types of signal quality, which is not specifically limited here.

The UE reports the CSI measurement result to the access network side device. The preset time period at which the report time is located may be within a period of time starting from the wake-up time, such as two time gaps. The specific time is not limited here. The UE can report the CSI measurement result to the access network side device through the PUCCH, and can also report the CSI measurement result to the access network side device through the PUSCH. The specific reporting channel is not limited here.

If the UE performs CSI measurement and reports CSI measurement results, or both are within the corresponding preset time period, step 703 is performed.

703. The access network side device determines the transmitting antenna port;

The access network side device determines the transmitting antenna port according to the CSI measurement result, and there may be one or more transmitting antenna ports.
