Description

Signal transmission method and device
Technical Field
The present application relates to the field of communications, and in particular, to a signal transmission method and apparatus.
Background
In Long Term Evolution (LTE) and New Radio (NR) of the fifth generation (5G) mobile communication system, a connected discontinuous reception cycle (C-DRX cycle, which may also be referred to as a DRX cycle for short generally) is defined. As shown in FIG. 1, the C-DRX cycle consists of "On Duration" and "Opportunity for DRX". Wherein, the On Duration may be referred to as a start Duration, and the Opportunity for DRX may be referred to as a DRX Opportunity. During the "On Duration", a User Equipment (UE) is in an active period, and can monitor and receive a PDCCH; during the "Opportunity for drx" period, the UE is in a sleep period and does not receive the PDCCH to reduce power consumption.
To further achieve the purpose of saving power consumption, in the standardized discussion of NR version 16 (release 16, Rel-16), a method based on a power saving signal (power saving signal) is proposed: before the C-DRX cycle starts (i.e., before the OnDuration), the network side sends a power saving signal to the UE, instructing the UE to enter a sleep state within one or more C-DRXcycles. Of course, the power saving signal may also be sent to wake up the terminal device in the sleep state.
There may be a certain time interval or time offset (offset) between the power saving signal and the OnDuration, which is used for processing the power saving signal (i.e. monitoring whether there is a power saving signal and analyzing the meaning of the power saving signal), time-frequency synchronization, Channel State Information (CSI) measurement, beam management (beam management), and other operations. However, the time interval between the power saving signal and the OnDuration is configured specifically, and the standard does not provide corresponding provisions at present.
Disclosure of Invention
The embodiment of the application provides a signal transmission method and a signal transmission device, which are used for configuring a time interval (also called offset) between a power consumption saving signal and an OnDuration.
In a first aspect, an embodiment of the present application provides a signal transmission method, including: the network equipment generates a first signal, wherein the first signal is used for indicating the terminal equipment to be in a sleep state or an awakening state in a first time interval; the network equipment sends a first signal to the terminal equipment at a first moment, wherein the first moment is earlier than the starting moment of a first time interval, a first time interval is arranged between the first moment and the starting moment of the first time interval, the value of the first time interval is one value in a target set, the target set comprises N values configured by the network equipment, and N is an integer greater than or equal to 2.
In the method provided by the embodiment of the application, the time interval between the first time and the start time of the first time interval has multiple values (i.e., multiple lengths), and the time interval can respectively correspond to different processing requirements of the terminal device. The different processing requirements of the terminal equipment mean that the terminal equipment needs to perform partial or all of the processing such as time-frequency synchronization, CSI measurement, beam management and the like in the first time interval under different conditions, and the more the processing is performed, the longer the required time is. For example, when the terminal device needs to perform time-frequency synchronization, the value of the first time interval may be set to be larger, and when the terminal device does not need to perform time-frequency synchronization, the value of the first time interval may be set to be smaller, so that the problem of power consumption waste caused by only configuring one value of the first time interval can be avoided.
With reference to the first aspect, in a first possible implementation manner of the first aspect, a value of the first time interval has a first corresponding relationship with a length of a first DRX cycle in which the first time interval is located.
With reference to the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the obtaining a first corresponding relationship between a value of the first time interval and a length of a first discontinuous reception DRX cycle in which the first time interval is located includes: when the first DRX period is a first period, the value of the first time interval is a first value in the target set; and when the first DRX period is the second period, the value of the first time interval is the second value in the target set.
With reference to the second possible implementation manner of the first aspect, in a third possible implementation manner of the first aspect, the first value is different from the second value. For example, when the first period is a long C-DRX period configured by the network device, and the second period is a short C-DRX period configured by the network device, the first value may be greater than the second value. This is because the terminal device needs to perform time-frequency synchronization operation in the long C-DRX cycle, and the terminal device may not perform time-frequency synchronization operation in the short C-DRX cycle, and therefore, the first value may be larger than the second value, so that the terminal device has enough time to perform time-frequency synchronization operation.
With reference to the first possible implementation manner of the first aspect, in a fourth possible implementation manner of the first aspect, the obtaining of the first time interval and the length of the first discontinuous reception DRX cycle in which the first time interval is located have a first corresponding relationship includes that when the length of the first DRX cycle is greater than a first threshold, the obtaining of the first time interval is a third value in the target set; when the length of the first DRX period is smaller than a first threshold value, the value of the first time interval is a fourth value in the target set; and when the length of the first DRX period is equal to the first threshold value, the value of the first time interval is a third value or a fourth value.
With reference to the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner of the first aspect, the third value is different from the fourth value. For example, when the length of the first DRX cycle is greater than or equal to the first threshold, the terminal device cannot maintain time-frequency synchronization, and therefore the terminal device needs to perform time-frequency synchronization operation; when the length of the first DRX cycle is smaller than the first threshold, the terminal device can maintain time-frequency synchronization, and therefore the terminal device does not need to perform time-frequency synchronization operation.
With reference to the fourth or fifth possible implementation manner of the first aspect, in a sixth possible implementation manner of the first aspect, the first threshold is reported by the terminal device or indicated by the network device. The terminal device may report the first threshold through RRC signaling, or a media access control element (MAC CE) for media access control, or Uplink Control Information (UCI). The network device may indicate the first threshold through RRC signaling, or MAC CE, or DCI, for example, n bits may be added in the DCI to indicate the first threshold.
With reference to the fourth to sixth possible implementation manners of the first aspect, in a seventh possible implementation manner of the first aspect, the first threshold is determined according to a time threshold for the terminal device to maintain time-frequency synchronization. For example, the first threshold may be equal to a time threshold at which the terminal device is able to maintain time-frequency synchronization. When the length of the first DRX period is greater than or equal to a first threshold value, the terminal equipment cannot maintain time-frequency synchronization, so that the terminal equipment needs to perform time-frequency synchronization operation; when the length of the first DRX cycle is smaller than the first threshold, the terminal device can maintain time-frequency synchronization, and thus the terminal device does not need to perform time-frequency synchronization operation.
With reference to the first aspect and the first possible implementation manner of the first aspect, in an eighth possible implementation manner of the first aspect, a value of the first time interval has a second corresponding relationship with a frequency domain resource location of a cell in which the terminal device is located.
With reference to the eighth possible implementation manner of the first aspect, in a ninth possible implementation manner of the first aspect, the step of making the value of the first time interval have a second corresponding relationship with the frequency domain resource location of the cell in which the terminal device is located includes: when the frequency domain resource position of the cell in which the terminal equipment is located is greater than a second threshold value, the value of the first time interval is a fifth value in the target set; when the frequency domain resource position of the cell in which the terminal equipment is located is smaller than a second threshold value, the value of the first time interval is a sixth value in the target set; and when the frequency domain resource position of the cell in which the terminal equipment is located is equal to the second threshold, the value of the first time interval is the fifth value or the sixth value.
With reference to the ninth possible implementation manner of the first aspect, in a tenth possible implementation manner of the first aspect, the fifth value is different from the sixth value. For example, the second threshold may be 6 Ghz. When the frequency domain resource position of the cell where the terminal equipment is located is greater than or equal to 6Ghz, the cell where the terminal equipment is located at a high-frequency point, and the terminal equipment needs to perform beam management; when the frequency domain resource position of the cell in which the terminal equipment is located is less than 6Ghz, the cell in which the terminal equipment is located at a low-frequency point, and the terminal equipment does not need to perform beam management; at this time, the fifth value may be greater than the sixth value, so that the terminal device has enough time to perform the beam management operation.
With reference to the eighth possible implementation manner of the first aspect, in an eleventh possible implementation manner of the first aspect, the step of having the second corresponding relationship between the value of the first time interval and the frequency domain resource location of the cell in which the terminal device is located includes: when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold and the length of the first DRX period is greater than or equal to the first threshold, the value of the first time interval is a seventh value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is an eighth value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to a second threshold and the length of the first DRX period is greater than or equal to a first threshold, the value of the first time interval is a ninth value in the target set; and when the frequency domain resource position of the cell in which the terminal equipment is located is less than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is the tenth value in the target set.

With reference to the thirteenth possible implementation manner of the first aspect, in a fourteenth possible implementation manner of the first aspect, the eleventh value is different from the twelfth value, for example, the eleventh value may be greater than the twelfth value.

Detailed Description
For clarity and conciseness of the following description of the various embodiments, a brief introduction to related concepts or technologies is first presented:
5G NR: the 5G NR is a subject recently proposed by the 3rd Generation partnership project (3 GPP) organization and is located in the 14 th Release 14 (Rel-14) of NR. In the last 10 years, the LTE standard proposed by the 3GPP organization has been widely used throughout the world, referred to as the 4th generation (4G) mobile communication technology. For example, china mobile, china unicom, and china telecom have adopted 4G LTE Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD) mode transmission technologies, respectively, and provide fast and convenient mobile network services for users.
As the new generation of 5G technologies enter the discussion phase, it is necessary to questione whether the system architecture and access procedures that have been achieved in the original 4G LTE technology continue to be adopted. On the one hand, since communication systems are latter-compatible, new technologies developed later tend to be compatible with technologies that have been previously standardized; on the other hand, since 4G LTE already has a lot of existing designs, if compatibility is achieved, much of the flexibility of 5G must be sacrificed, thereby reducing performance. Therefore, two directions are currently being investigated in parallel in the 3GPP organization, and in both directions, the technology discussion group without regard to backward compatibility, is called 5G NR.
Beam management: the bands deployed in the NR system include both low frequency bands, i.e., frequency range 1 below 6GHz (FR 1), and high frequency bands, i.e., frequency range2 above 6GHz (FR 2), such as millimeter waves.
As shown in fig. 2, in the low frequency band, a single antenna can radiate omni-directionally, and the distance of electromagnetic signals propagating in all directions is the same. In the high frequency band, the electromagnetic wave wavelength is shortened, so that the size of the antenna can be correspondingly reduced, and a large-scale antenna array can be used for communication. The antenna array formed by the antennas can perform directional radiation, energy can be concentrated in a narrower direction to form a beam, the propagation distance of electromagnetic signals is longer, the direction is more concentrated, the communication performance is enhanced, and therefore energy waste is reduced.
When the beam mode is used for communication, the beam between the base station and the UE must be aligned for normal communication. In order to ensure beam alignment between the base station and the UE, beam management is required. For example, as shown in fig. 3 (a), the beam (beam) of the base station and the beam of the UE are both directed to each other to communicate. As shown in (b), (c), and (d) of fig. 3, if any of the beams is not directed to the other, normal communication cannot be performed.
Carrier Aggregation (CA): in the initial stage of LTE standard development, a maximum bandwidth of 20MHz for one carrier is specified. In a later standardization process, LTE is further improved, referred to as evolved LTE (LTE-Advanced, LTE-a). In order to meet the requirements of 1Gbps downlink peak speed and 500Mbps uplink peak speed specified in LTE-A, the maximum transmission bandwidth of 100MHz needs to be provided. Due to the scarcity of continuous spectrum with large bandwidth, LTE-a proposes a solution for carrier aggregation. Carrier aggregation is to aggregate 2 or more Component Carriers (CCs) together to support a larger transmission bandwidth (up to 100 MHz). Each CC corresponds to an independent cell (cell), and 1 CC may also be equivalent to 1 cell. The maximum bandwidth per CC may be 20 MHz.
Starting from version 10 (Release 10, Rel-10), CA was introduced into the standard. At most, 5 CCs may be configured for one UE, where one CC corresponds to a primary cell (PCell) and the remaining CCs correspond to secondary cells (scells). Among them, the PCell is responsible for Radio Resource Control (RRC) communication with the UE, and a Physical Uplink Control Channel (PUCCH) can only be transmitted on the PCell. The Pcell may be a cell where the UE performs initial connection establishment, or a cell where RRC connection reestablishment is performed, or a cell designated in a handover (handover) procedure. SCell is a cell added at RRC reconfiguration to provide additional radio resources.
Starting from Release 13 (Rel-13), enhanced CA (eCA) was introduced into the standard, and a UE can be configured with up to 32 CCs. In NR, ecas may also be used, where uplink and downlink may support 16 CCs at most, respectively. Meanwhile, when the base station bandwidth is large and the UE capability is insufficient and cannot support such a large bandwidth through a single carrier, the UE may support the large bandwidth through an intra-band continuous ca (intra-band connectivity ca). For example, when the bandwidth of the base station is 400MHz, and the maximum continuous bandwidth that can be supported by the UE is 100MHz, the UE may regard the bandwidth of the base station as an aggregation of 4 bandwidths of 100MHz, and communicate with the base station in a CA manner.
C-DRX: the cycle length (C-DRX cycle length) of the C-DRX includes the lengths of the active period and the dormant period. In one set of C-DRX configurations, the base station may configure two cycles for the UE, namely, a short C-DRX cycle (short C-DRX) and a long C-DRX cycle (long C-DRX), where the cycle lengths are different, and the UE may switch between the two cycles. Wherein, the cycle length of the short C-DRX cycle ranges from 2ms to 640ms, and the cycle length of the long C-DRX cycle ranges from 10ms to 10240 ms. Currently, when a base station configures C-DRX for UEs, each UE has only one set of configuration. In the CA scenario, each CC follows the same cycle of C-DRX, length of active period and dormant period, i.e. the UE wakes up and sleeps on each CC.
Power consumption saving signal: the network device may send a power saving signal to the terminal device indicating that the terminal device is in a sleep state for one or more C-DRX cycles to save power consumption of the terminal device. The network device may also send a power saving signal to the terminal device to wake up the terminal device. There is a time interval, which may be referred to as offset for short, between the power saving signal and the On Duration of the C-DRX cycle. I.e. there is a time interval between the time when the network device issues the power saving signal (or the time when the terminal device receives the power saving signal) and the start time of the C-DRX cycle. The time interval is used for processing power consumption saving signals (i.e., monitoring whether power consumption saving signals exist or not and analyzing meanings thereof), time-frequency synchronization, Channel State Information (CSI) measurement, beam management (beam management), and other processing operations.
Whether time-frequency synchronization and/or CSI measurement is needed before the On Duration for a UE may depend On the sleep (sleep) state of the UE and/or the Duration of the sleep state of the UE. The sleep state of the UE may be, for example, light sleep or deep sleep. For example, for a UE, if time-frequency synchronization with a base station needs to be maintained, a downlink signal sent by the base station needs to be received, time-frequency offset (the offset is caused by that respective crystal oscillators of the UE and the base station are not identical) estimation is performed according to the downlink signal, and the offset is compensated. When the UE is in deep sleep (deep sleep), that is, the time in the sleep state is long, and the UE is not receiving the downlink signal sent by the base station, the UE may be out of synchronization with the time and frequency of the base station; when the UE is in a light sleep (i.e. the time in the sleep state is short), the UE can maintain time-frequency synchronization (i.e. the error with the base station is small), and the UE can receive a downlink signal to correct the offset when the UE wakes up next time.
Whether beam management is needed before the On Duration for a UE may depend On the frequency of the cell in which the UE is located. For example, when the frequency of the cell in which the UE is located is high, for example, greater than 6Ghz, the UE may employ a beam transmission technology, and therefore beam management is required; when the frequency of the cell in which the UE is located is low, for example, less than 6Ghz, the UE may not employ the beam transmission technology, and beam management is not needed.
In the current standard discussion, it is proposed that the offset between the power saving signal and the On Duration is a configurable value. As shown in fig. 4, assuming that the base station configures an offset value (assumed to be offset 0) for the UE, when the C-drx cycle length of the UE is "length 1", the UE needs time-frequency synchronization and CSI measurement, and the UE can perform time-frequency synchronization and CSI measurement within the entire duration of offset 0. When the C-DRX cycle length of the UE becomes "length 2", the UE does not need time-frequency synchronization in fact, but only needs to perform CSI measurement, that is, the UE only needs to perform CSI measurement within a part of the Duration of offset0, and then the UE may only enter a shallow sleep state or even a sleep state during the time before the On Duration, thereby causing waste of power consumption.
The embodiment of the application provides a signal transmission method and a signal transmission device, which are applied to the transmission process of signals (such as power consumption saving signals). Specifically, the network device may send a power saving signal to the terminal device, where the power saving signal may indicate how long the terminal device remains in the awake state for normal data transceiving, for example, the power saving signal may indicate that the terminal device remains in the awake state in one or more DRX cycles. Alternatively, the power saving signal may indicate how long the terminal device remains in the sleep state, e.g., the power saving signal may indicate that the terminal device remains in the sleep state for one or more DRX cycles to save power consumption.
A time interval is formed between the moment when the network equipment sends the power consumption saving signal and the starting moment when the terminal equipment keeps the awakening state or the sleeping state according to the power consumption saving signal. The time interval may have different values in different cases. For example, in different sleep states of the terminal device, values of the time interval are different. When the terminal device is in the shallow sleep, the value of the time interval may be smaller than the value of the time interval when the terminal device is in the deep sleep. For another example, when the frequencies of the cells in which the terminal devices are located are different, the values of the time intervals are different. The value of the time interval when the terminal device is in the low frequency cell may be smaller than the value of the time interval when the terminal device is in the high frequency cell. For another example, in different sleep states of the terminal device, and at the same time of the frequency of the cell where the terminal device is located, the values of the time intervals are different. In this application, the time interval may also be referred to as a time offset or as an offset.
Under different conditions, the terminal device needs to perform partial or all of the time-frequency synchronization, CSI measurement, beam management and other processing in the first time interval, and the more the processing is performed, the longer the required time is. In the method provided by the embodiment of the application, the time interval between the first time and the start time of the first time interval has multiple values (i.e., multiple lengths), and the time interval can respectively correspond to different processing requirements of the terminal device. For example, when the terminal device is in deep sleep, time-frequency synchronization is required, the value of the first time interval can be set to be larger, when the terminal device is in shallow sleep, the value of the first time interval can be set to be smaller without performing time-frequency synchronization, and the problem of power consumption waste caused by only configuring one value of the first time interval can be avoided.
The embodiment of the application can be applied to various wireless communication systems such as an LTE system, a 5G NR system, a next generation wireless local area network system and the like.
As shown in fig. 5, a communication system suitable for the signal transmission method provided in the embodiment of the present application may include a network device 100 (e.g., a base station) and one or more terminal devices 200 (only 1 is shown in fig. 2) connected to the network device 100. After the network equipment generates the first signal, the first signal is sent to the terminal equipment at the first moment, and the terminal equipment receives the first signal from the network equipment at the first moment. The first signal is used for indicating the terminal device to be in a sleep state or an awake state in a first time interval, a first time interval is arranged between a first moment and a starting moment of the first time interval, a value of the first time interval is one value in a target set, the target set comprises N values, and N is an integer greater than or equal to 2.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, "at least one" means one or more, "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.
For the sake of understanding, the signal transmission method provided by the embodiments of the present application is specifically described below with reference to the accompanying drawings.
As shown in fig. 6, an embodiment of the present application provides a signal transmission method, including:
601. the network equipment generates a first signal, and the first signal is used for indicating that the terminal equipment is in a sleep state or an awakening state in a first time interval.
The first time interval may include one or more DRX cycles (e.g., C-DRX cycles), or the first time interval may include one or more On durations, or the first time interval may include one or more opportunities for DRX. For example, the first signal may indicate that the terminal device is in a sleep state for the next 3C-DRX cycles, i.e., 3C-DRX cycles that come after the network device transmits the first signal. For another example, the first signal may indicate that the terminal device is in a sleep state for the next 2 On durations. For another example, the first signal may indicate that the terminal device is in an awake state within the next 2 opportunities for DRX.
Optionally, if the first time interval includes multiple DRX cycles, the first DRX cycle is a first DRX cycle in the multiple DRX cycles, that is, a first DRX cycle that comes after the network device sends the first signal. If the first time interval includes a plurality of On durations, the first DRX cycle is a DRX cycle in which a first On Duration of the plurality of On durations is located, i.e., a first DRX cycle that comes after the network device sends the first signal. If the first time interval includes multiple Opportunity for DRX, the first DRX cycle is a DRX cycle in which a first Opportunity for DRX of the multiple Opportunity for DRX is located, that is, a first DRX cycle that comes after the network device sends the first signal.
For example, when the first signal is used to indicate that the terminal device is in the sleep state in the first time interval, if the terminal device is in the awake state based on the C-DRX mechanism or an indication of the network device (e.g., previously indicated by the network device through the first signal or indicated by other information), the terminal device may switch to the sleep state in the first time interval to save power consumption of the terminal device; if the terminal device is in the sleep state based on the C-DRX mechanism or the indication of the network device, the terminal device may continue to be in the sleep state within the first time interval to save power consumption of the terminal device. When the first signal is used for indicating that the terminal equipment is in the awakening state in the first time interval, if the terminal equipment is in the sleeping state based on the C-DRX mechanism or the indication of the network equipment, the terminal equipment can awaken from the sleeping state and keep in the awakening state in the first time interval; if the terminal device is in the wake-up state based on the C-DRX mechanism or the indication of the network device, the terminal device may continue to maintain the wake-up state for the first time interval.
In one possible design, the terminal device being in a sleep state includes at least one of:
(1) the terminal device does not monitor the PDCCH to save power consumption of the terminal device.
For example, the terminal device does not receive Downlink Control Information (DCI) carried in the PDCCH channel, so as to save power consumption of the terminal device.
(2) The terminal device does not receive the downlink reference signal sent by the network device, so that the power consumption of the terminal device is saved.
The downlink reference signal may include at least one of the following: cell-specific reference signals (CRS), also called common reference signals, are used for channel estimation and associated demodulation for all downlink transmission techniques except beamforming techniques that are not based on codebooks. Multicast/multicast single frequency network reference signals (MBSFN-RS) for MBSFN channel estimation and coherent demodulation. A mobile-specific reference signal (UE-specific rs) for channel estimation and associated demodulation for non-codebook based beamforming techniques. A channel state information reference signal (CSI-RS) for demodulation of horizontal spread angle information and vertical tilt angle information of the transmitting unit. Synchronization Signal Block (SSB) for time-frequency synchronization, beam management, and Radio Resource Management (RRM) measurements. A Tracking Reference Signal (TRS) is used for time-frequency tracking and other functions.
(3) The terminal device does not make measurements to save power consumption of the terminal device.
For example, the terminal device not performing the measurement may include: the terminal device does not perform RRM measurement and/or the terminal device does not perform CSI measurement to save power consumption of the terminal device.
It should be understood that the terminal device does not perform measurement, and may be that the terminal device does not receive a reference signal for measurement, or may be that the terminal device does not process the received reference signal. For example, the terminal device does not perform RRM measurement, and may be that the terminal device does not receive the SSB or does not process the received SSB. For another example, the terminal device does not perform CSI measurement, and may not receive the CSI reference signal or process the received CSI reference signal.
In one possible design, the terminal device being in the awake state includes at least one of: (1) and the terminal equipment monitors a Physical Downlink Control Channel (PDCCH). (2) And the terminal equipment receives the downlink reference signal sent by the network equipment. (3) And the terminal equipment performs measurement. For the related description, reference may be made to the above description, which is not repeated herein.
602. The network device sends a first signal to the terminal device at a first time.
The first time is earlier than the starting time of the first time interval, a first time interval is arranged between the first time and the starting time of the first time interval, the value of the first time interval is one value in a target set, the target set comprises N values configured by the network equipment, and N is an integer greater than or equal to 2. The network device may pre-store N values in the target set, or the network device may configure and update the N values in the target set based on a big data method, which is not limited in this application. Wherein the size of each of the N values may be greater than or equal to 0.
In this application, the first time interval may also be referred to as a first time offset or as a first offset. The value of the first time interval is dynamic or non-fixed. In an aspect, the first time interval may have different values for a terminal device under different conditions (e.g., in different DRX cycles). On the other hand, for a plurality of terminal devices, values of the first time intervals respectively corresponding to different terminal devices may be different. For example, when the first terminal device is in the long C-DRX cycle and the second terminal device is in the short C-DRX cycle, the value of the first time interval corresponding to the first terminal device is different from the value of the first time interval corresponding to the second terminal device.
In one possible design, a value of the first time interval has a first corresponding relationship with a length of a first DRX cycle in which the first time interval is located. The DRX cycle may include a C-DRX cycle, for example, the first DRX cycle may be a first C-DRX cycle.
In one possible design, when the first DRX cycle is the first cycle, the value of the first time interval is the first value in the target set; when the first DRX period is a second period, the value of the first time interval is a second value in the target set; wherein the first value is different from the second value.
In a possible design, when the first period is a long C-DRX period configured by the network device, and the second period is a short C-DRX period configured by the network device, the first value may be greater than the second value. This is because the terminal device needs to perform time-frequency synchronization operation in the long C-DRX cycle, and the terminal device may not perform time-frequency synchronization operation in the short C-DRX cycle, and therefore, the first value may be larger than the second value, so that the terminal device has enough time to perform time-frequency synchronization operation.
Optionally, whether in the long C-DRX cycle or in the short C-DRX cycle, the terminal device may perform operations such as CSI measurement and/or beam management in the first time interval.
In one possible design, when the length of the first DRX cycle is greater than a first threshold, the value of the first time interval is a third value in the target set; when the length of the first DRX period is smaller than a first threshold value, the value of the first time interval is a fourth value in the target set; when the length of the first DRX period is equal to a first threshold value, the value of the first time interval is a third value or a fourth value; wherein the third value is different from the fourth value.
The first threshold may be determined according to a time threshold for the terminal device to maintain time-frequency synchronization. For example, the first threshold may be equal to a time threshold at which the terminal device is able to maintain time-frequency synchronization. When the length of the first DRX period is greater than or equal to a first threshold value, the terminal equipment cannot maintain time-frequency synchronization, so that the terminal equipment needs to perform time-frequency synchronization operation; when the length of the first DRX cycle is smaller than the first threshold, the terminal device can maintain time-frequency synchronization, and therefore the terminal device does not need to perform time-frequency synchronization operation.
Optionally, the first threshold may be reported by the terminal device or indicated by the network device. For example, the terminal device may report the first threshold through RRC signaling, or MAC CE, or UCI. The network device may indicate the first threshold through RRC signaling, or MAC CE, or DCI, for example, n bits may be added in the DCI to indicate the first threshold. Optionally, the terminal device may report the relevant capability to the network device to indicate a time threshold for the terminal device to maintain time-frequency synchronization.
In a possible design, a value of the first time interval has a second correspondence with a frequency domain resource location of a cell in which the terminal device is located. The frequency domain resource location of the cell in which the terminal device is located is the frequency range, frequency point or frequency band of the cell in which the terminal device is located.
In a possible design, when the frequency domain resource position of the cell in which the terminal device is located is greater than a second threshold, the value of the first time interval is a fifth value in the target set; when the frequency domain resource position of the cell in which the terminal equipment is located is smaller than a second threshold value, the value of the first time interval is a sixth value in the target set; when the frequency domain resource position of the cell where the terminal equipment is located is equal to the second threshold, the value of the first time interval is a fifth value or a sixth value; wherein the fifth value is different from the sixth value.
For example, the second threshold may be 6 Ghz. When the frequency domain resource position of the cell where the terminal equipment is located is greater than or equal to 6Ghz, the cell where the terminal equipment is located at a high-frequency point, and the terminal equipment needs to perform beam management; when the frequency domain resource position of the cell in which the terminal equipment is located is less than 6Ghz, the cell in which the terminal equipment is located at a low-frequency point, and the terminal equipment does not need to perform beam management; at this time, the fifth value may be greater than the sixth value, so that the terminal device has enough time to perform the beam management operation.
In a possible design, a value of the first time interval has a first corresponding relationship with a length of a first DRX cycle in which the first time interval is located, and a value of the first time interval has a second corresponding relationship with a frequency domain resource location of a cell in which the terminal device is located.
In one possible design, when the frequency domain resource position of the cell where the terminal device is located is greater than or equal to the second threshold and the length of the first DRX cycle is greater than or equal to the first threshold, the value of the first time interval is a seventh value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is an eighth value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to a second threshold and the length of the first DRX period is greater than or equal to a first threshold, the value of the first time interval is a ninth value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is the tenth value in the target set; the seventh value is different from the eighth value, for example, the seventh value may be larger than the eighth value. The ninth value is different from the tenth value, for example, the ninth value is greater than the tenth value.
In one possible design, when the frequency domain resource location of the cell in which the terminal device is located is greater than or equal to the second threshold and the first DRX cycle is the first cycle (e.g., the long C-DRX cycle), the value of the first time interval is the eleventh value in the target set; and when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to the second threshold and the first DRX cycle is the second cycle (e.g., short C-DRX cycle), the value of the first time interval is the twelfth value in the target set. When the frequency domain resource position of the cell where the terminal device is located is greater than or equal to a second threshold and the first DRX cycle is a second cycle, the value of the first time interval is a thirteenth value in the target set; and when the frequency domain resource position of the cell in which the terminal equipment is located is less than or equal to the second threshold and the first DRX period is the second period, the value of the first time interval is the fourteenth value in the target set. The eleventh value is different from the twelfth value, for example, the eleventh value may be greater than the twelfth value. The thirteenth value is different from the fourteenth value, for example, the thirteenth value is greater than the fourteenth value.
It should be noted that, the above example shows the possibility of various values of the first time interval when the frequency domain resource location of the cell in which the terminal device is located is greater than, equal to, or less than the second threshold, and/or the length of the first DRX cycle is greater than, equal to, or less than the first threshold. Moreover, the above example shows the possibility of various values of the first time interval when the frequency domain resource location of the cell in which the terminal device is located is greater than, equal to, or less than the second threshold, and/or the first DRX cycle is the first cycle or the second cycle. It should be understood that the above description is only a specific embodiment of the present application, and is not intended to limit the scope of the present application. For example, in practical applications, only some of the possibilities may be included, and the present application is not limited thereto.
In a possible design, the first corresponding relationship and/or the second corresponding relationship are/is indicated by signaling; for example, it may be indicated by the network device through RRC signaling or MAC CE or DCI. Alternatively, the first correspondence and/or the second correspondence are predefined. I.e. the first correspondence and/or the second correspondence may be pre-stored on the terminal device and the network device. The first corresponding relation and/or the second corresponding relation may be indicated or pre-stored in a table form, or may be indicated or pre-stored in a formula form, or may be pre-stored on the terminal device and the network device in a pseudo code form.
For example, assuming that the first corresponding relationship is indicated in the form of a table or pre-stored, the first corresponding relationship may be as shown in table 1 or table 2:
TABLE 1
Length of first DRX cycle Value of the first time interval
First period First value
Second period The second value
TABLE 2
Length of first DRX cycle Value of the first time interval
First length (greater than or equal to first threshold) Third value
Second length (less than first threshold) The fourth value
Assuming that the first corresponding relationship is indicated in the form of a formula or pre-stored, the first corresponding relationship may be as shown in formula (1):
Figure BDA0002047923880000311
wherein, a represents the DRX cycle length of the terminal device, B represents the first threshold, and C or D represents the value of the first time interval.
In one possible design, before the network device sends the first signal to the terminal device at the first time, the terminal device reports at least two suggested time interval values to the network device, where any one of the at least two suggested time interval values is used to indicate a value of a first time interval desired by the terminal device.
In one possible design, the suggested time interval value includes a first suggested time interval value and a second suggested time interval value, the first suggested time interval value corresponds to a first operation performed by the terminal device between the first time and a starting time of the first time interval, and the second suggested time interval value corresponds to a second operation performed by the terminal device between the first time and the starting time of the first time interval.
For example, the first operation may include making CSI measurements and the second operation may not include making CSI measurements. At this time, since the terminal device needs more processing time to receive the reference signal and process the signal when performing the CSI measurement, the first time interval suggested value may be greater than the second time interval suggested value. Alternatively, the first operation may include performing beam management and the second operation may not include performing beam management. Similarly, the terminal device needs more processing time to receive the reference signal and process the signal when performing the beam management measurement, so that the first time interval recommended value may be larger than the second time interval recommended value. Alternatively, the first operation includes transmitting a sounding reference signal, SRS, and the second operation does not include transmitting an SRS. Similarly, the terminal device needs more processing time to prepare a signal to be transmitted and transmit the signal when transmitting the SRS, and therefore the first time interval suggested value may be larger than the second time interval suggested value. Or, the first operation includes performing time-frequency synchronization, and the second operation does not include performing time-frequency synchronization. Similarly, the terminal device needs more processing time for receiving the reference signal and processing the signal when performing time-frequency synchronization, so that the first time interval suggested value may be greater than the second time interval suggested value.
603. The terminal device receives a first signal from the network device at a first time.
When the first signal is used for indicating that the terminal device is in the sleep state in the first time interval, the terminal device enters the sleep state at the start position of the first time interval, and the terminal device can be in the sleep state until the first time interval is finished without following a C-DRX mechanism in the first time interval, so that the power consumption of the terminal device is saved. Of course, if the terminal device is in the sleep state in the first time interval, the network device instructs the terminal device to wake up from the sleep state, and the terminal device may wake up from the sleep state. After the terminal device wakes up, the C-DRX mechanism may continue to be followed.
The first time and the starting time of the first time interval have a first time interval. In one possible design, a value of the first time interval has a first corresponding relationship with a length of a first DRX cycle in which the first time interval is located.
In one possible design, when the first DRX cycle is the first cycle, the value of the first time interval is the first value in the target set; when the first DRX period is a second period, the value of the first time interval is a second value in the target set; wherein the first value is greater than the second value.
For example, as shown in FIG. 7a, when a long C-DRX period is used, the position of offset1 is monitored for the first signal before the start Duration (On Duration) of the long C-DRX period, and time-frequency synchronization is performed. Optionally, operations such as CSI measurement and/or beam management may be performed accordingly. offset1 indicates that the first time interval is a first value. When the terminal device uses the short C-DRX cycle, the position of offset 2 before the start duration of the short C-DRX cycle monitors the first signal, and the terminal device does not need to perform time-frequency synchronization operation, but can perform operations such as CSI measurement and/or beam management accordingly. offset 2 represents the second value for the first time interval.
In one possible design, when the length of the first DRX cycle is greater than a first threshold, the value of the first time interval is a third value in the target set; when the length of the first DRX period is smaller than a first threshold value, the value of the first time interval is a fourth value in the target set; when the length of the first DRX period is equal to a first threshold value, the value of the first time interval is a third value or a fourth value; wherein the third value is greater than the fourth value.
For example, as shown in fig. 7b, when the terminal device uses the C-DRX of the first length, the terminal device monitors the first signal at the position offset3 before the start Duration (On Duration) of the C-DRX of the first length, and performs the time-frequency synchronization operation. Optionally, operations such as CSI measurement and/or beam management may be performed accordingly. The first length is greater than or equal to a first threshold, and offset3 indicates that the first time interval is at a third value. When the terminal device uses the C-DRX with the second length, the position of offset4 before the start duration (OnDuration) of the C-DRX with the second length monitors the first signal, and may not perform the time-frequency synchronization operation, but may perform operations such as CSI measurement and/or beam management accordingly. The second length is less than the first threshold and offset4 indicates that the first time interval is at the fourth value.
In a possible design, a value of the first time interval has a second correspondence with a frequency domain resource location of a cell in which the terminal device is located. Exemplarily, when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold, the value of the first time interval is a fifth value in the target set; when the frequency domain resource position of the cell in which the terminal equipment is located is smaller than a second threshold value, the value of the first time interval is a sixth value in the target set; when the frequency domain resource position of the cell where the terminal equipment is located is equal to the second threshold, the value of the first time interval is a fifth value or a sixth value; wherein the fifth value is greater than the sixth value.
For example, as shown in fig. 8, when the frequency domain resource location of the cell in which the terminal device is located is FR1, the terminal device monitors the first signal at the location of offset 5 before the start Duration (On Duration) of C-DRX, and performs the beam management operation. Optionally, CSI measurement and/or time-frequency synchronization may be performed accordingly. FR1 is greater than or equal to the second threshold and offset 5 indicates that the first time interval is at the fifth value. When the frequency domain resource location of the cell in which the terminal device is located is FR2, the first signal is monitored at the location offset 6 before the start Duration (On Duration) of C-DRX, and the CSI measurement and/or time-frequency synchronization may be performed accordingly without performing the beam management operation. FR2 is less than the second threshold and offset 6 indicates that the first time interval is at the sixth value.
In a possible design, a value of the first time interval has a first corresponding relationship with a length of a first DRX cycle in which the first time interval is located, and a value of the first time interval has a second corresponding relationship with a frequency domain resource location of a cell in which the terminal device is located.
Exemplarily, when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold and the length of the first DRX cycle is greater than or equal to the first threshold, the value of the first time interval is a seventh value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is greater than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is an eighth value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to a second threshold and the length of the first DRX period is greater than or equal to a first threshold, the value of the first time interval is a ninth value in the target set; when the frequency domain resource position of the cell in which the terminal device is located is less than or equal to the second threshold and the length of the first DRX period is less than or equal to the first threshold, the value of the first time interval is the tenth value in the target set; wherein the seventh value is greater than the eighth value; the ninth value is greater than the tenth value.
For example, as shown in fig. 9a, when the frequency domain resource location of the cell in which the terminal device is located is FR1, and the terminal device uses the C-DRX of the first length, the terminal device monitors the first signal at the offset7 position before the start Duration (On Duration) of the C-DRX of the first length, and performs time-frequency synchronization and beam management operations. Optionally, CSI measurement and other operations may be performed accordingly. FR1 is greater than or equal to the second threshold, and the first length is greater than or equal to the first threshold, and offset7 indicates that the first time interval is at the seventh value. The frequency domain resource location of the cell in which the terminal device is located is FR1, and when the terminal device uses the C-DRX with the second length, the terminal device monitors the first signal at the offset 8 location before the start Duration (On Duration) of the C-DRX with the first length, and may not perform the time-frequency synchronization operation but perform the beam management operation. Optionally, CSI measurement and other operations may be performed accordingly. FR1 is greater than or equal to the second threshold and the second length is less than the first threshold, and offset 8 indicates that the first time interval is at the eighth value. As shown in fig. 9b, when the frequency domain resource location of the cell in which the terminal device is located is FR2, and the terminal device uses the C-DRX of the first length, the terminal device monitors the first signal at the offset9 position before the start Duration (On Duration) of the C-DRX of the first length, and may not perform the beam management operation but perform the time-frequency synchronization operation. Optionally, CSI measurement and other operations may be performed accordingly. FR2 is smaller than the second threshold, and the first length is greater than or equal to the first threshold, and offset9 indicates that the first time interval is the ninth value. The frequency domain resource location of the cell in which the terminal device is located is FR2, and when the terminal device uses the C-DRX with the second length, the terminal device monitors the first signal at the offset10 location before the start Duration (On Duration) of the C-DRX with the first length, and may not perform the beam management and the time-frequency synchronization operation, and optionally may perform operations such as CSI measurement, and the like, accordingly. FR2 is smaller than the second threshold and the second length is smaller than the first threshold, and offset10 indicates that the first time interval is the tenth value.
604. The terminal equipment keeps a sleep state or an awakening state in a first time interval according to the first signal.
When the first signal is used to indicate that the terminal device is in a sleep state in a first time interval, if the terminal device is in an awake state based on a C-DRX mechanism or an indication of the network device (for example, the network device is indicated by the first signal or by other information before), the terminal device may switch to the sleep state in the first time interval to save power consumption of the terminal device; if the terminal device is in the sleep state based on the C-DRX mechanism or the indication of the network device, the terminal device may continue to be in the sleep state within the first time interval to save power consumption of the terminal device. When the first signal is used for indicating that the terminal equipment is in the awakening state in the first time interval, if the terminal equipment is in the sleeping state based on the C-DRX mechanism or the indication of the network equipment, the terminal equipment can awaken from the sleeping state and keep in the awakening state in the first time interval; if the terminal device is in the wake-up state based on the C-DRX mechanism or the indication of the network device, the terminal device may continue to maintain the wake-up state for the first time interval.
In one possible design, the terminal device may perform the first processing or operation within a first time interval after receiving the first signal. Wherein the first processing or operation may include at least one of parsing of the first signal, time-frequency synchronization processing, CSI measurement, beam management.
It should be noted that, there is no necessary execution sequence between steps 601 and 604, and the execution sequence between the steps is not specifically limited in this embodiment.
In the following, the signal transmission method provided by the embodiment of the present application is introduced by taking a network device as the base station 100 and a terminal device as the mobile phone 200 as an example, in combination with the application scenarios and beneficial effects of the embodiment of the present application.
As shown in fig. 9C, to save power consumption of the handset 200 or to wake up the handset 200, the base station 100 generates a first signal, which may be used to indicate that the handset 200 is in a sleep state or an awake state for one or more C-DRX cycles. The base station 100 determines the starting time of the start duration of the next C-DRX cycle (upcoming C-DRX cycle) of the handset 200 and determines a first time earlier than the starting time. The first time and the starting time have a first time interval therebetween. The value of the first time interval may be selected from a plurality of values of the first time intervals pre-stored in the base station 100. When the base station determines that the current handset 200 is currently in the long C-DRX cycle, it may determine that the value of the first time interval is offset00, where offset00 corresponds to the long C-DRX cycle. The base station 100 transmits the first signal at the first time, and the handset 200 receives the first signal at the first time. Handset 200 may perform time-frequency synchronization, CSI measurement, and/or beam management operations within offset 00. When the base station determines that the current handset 200 is currently in the short C-DRX cycle, it may be determined that the value of the first time interval is offset01, where offset01 corresponds to the short C-DRX cycle. The base station 100 transmits the first signal at the first time, and the handset 200 receives the first signal at the first time. Handset 200 may perform CSI measurements and/or beam management operations within offset 01.
The foregoing example describes that the value of the first time interval has a corresponding relationship with the length of the C-DRX cycle, but the present application is not limited thereto, and the value of the first time interval may have a corresponding relationship with the frequency domain resource location of the cell in which the terminal device is located, or the value of the first time interval may have a corresponding relationship with both the length of the C-DRX cycle and the frequency domain resource location of the cell in which the terminal device is located.
Based on the method provided by the embodiment of the application, the network device sends a first signal to the terminal device at a first time to indicate that the terminal device is in a sleep state or an awake state in a first time interval, and a first time interval is formed between the first time and the starting time of the first time interval. The value of the first time interval is not a fixed value, and can have various values, so that different processing requirements of the terminal equipment can be met. The different processing requirements of the terminal equipment mean that the terminal equipment needs to perform partial or all of the processing such as time-frequency synchronization, CSI measurement, beam management and the like in the first time interval under different conditions, and the more the processing is performed, the longer the required time is. In the method provided by the embodiment of the application, the time interval between the first time and the start time of the first time interval has multiple values (i.e., multiple lengths), and the time interval can respectively correspond to different processing requirements of the terminal device. For example, when the terminal device needs to perform time-frequency synchronization, the value of the first time interval may be set to be larger, and when the terminal device does not need to perform time-frequency synchronization, the value of the first time interval may be set to be smaller, so that the problem of power consumption waste caused by only configuring one value of the first time interval can be avoided.
As shown in fig. 10, an embodiment of the present application provides a signal transmission method, including: 1001-1008 steps.
Specifically, in step 1001, the network device generates a first signal, where the first signal is used to indicate that the terminal device is in a sleep state or an awake state in a first time interval. The specific process may refer to step 601. In step 1002, the network device sends a first signal to the terminal device at a first time, where the first time is earlier than a start time of a first time interval, and the first time and the start time of the first time interval have a first time interval therebetween. The specific process may refer to step 602. In step 1003, the terminal device receives a first signal from the network device at a first time. The specific process may refer to step 603. In step 1004, the terminal device maintains a sleep state or an awake state for a first time interval according to the first signal. The specific process may refer to step 604. In step 1005, the network device generates a second signal, where the second signal is used to indicate that the terminal device is in the sleep state or the awake state in the second time interval. The second signal is generated later than the first signal. For the description of the second signal, reference may be made to the description of the first signal in the embodiment shown in fig. 6, which is not repeated herein. In step 1006, the network device sends a second signal to the terminal device at a second time, where the second time is earlier than the start time of the second time interval, and the second time and the start time of the second time interval have a second time interval therebetween.
In one possible design, the first time interval is different from the second time interval.
In one possible design, a value of the second time interval and a length of a second DRX cycle in which the second time interval is located have a third correspondence. The third correspondence is indicated or predefined by signaling, for example, the third correspondence may be indicated by the network device through RRC signaling or MAC CE or DCI, or the third correspondence may be prestored on the terminal device and the network device. The manner of indicating or predefining the third corresponding relationship may refer to the description of the manner of indicating or predefining the first corresponding relationship or the second corresponding relationship in the embodiment shown in fig. 6, which is not repeated herein.
In one possible design, when the second DRX cycle is the first cycle, the value of the second time interval is the first value; and when the second DRX period is the second period, the value of the second time interval is the second value. The first value and the second value may refer to the description in the embodiment shown in fig. 6, and are not described herein again. The first cycle may be a long C-DRX cycle configured by the network device, and the second cycle may be a short C-DRX cycle configured by the network device.
In one possible design, when the length of the second DRX cycle is greater than the first threshold, the value of the first time interval is a third value; when the length of the second DRX period is smaller than the first threshold value, the value of the first time interval is a fourth value; and when the length of the second DRX period is equal to the first threshold value, the value of the first time interval is a third value or a fourth value. The third value and the fourth value may refer to the description in the embodiment shown in fig. 6, and are not described herein again. The first threshold is reported by the terminal device or indicated by the network device, and the first threshold is determined according to a time threshold for the terminal device to maintain time-frequency synchronization, which may refer to the description in the embodiment shown in fig. 6 and is not described herein again.
In one possible design, the value of the second time interval has a fourth corresponding relationship with the frequency domain resource location of the second cell in which the terminal device is located. The fourth corresponding relationship is indicated or predefined by signaling, for example, the fourth corresponding relationship may be indicated by the network device through RRC signaling or MAC CE or DCI, or the fourth corresponding relationship may be pre-stored on the terminal device and the network device. The manner of indicating or predefining the fourth corresponding relationship may refer to the description of the manner of indicating or predefining the first corresponding relationship or the second corresponding relationship in the embodiment shown in fig. 6, which is not repeated herein.
In a possible design, when the frequency domain resource location of the second cell where the terminal device is located is greater than a second threshold, the value of the second time interval is a fifth value; when the frequency domain resource position of the second cell where the terminal device is located is smaller than a second threshold, the value of the second time interval is a sixth value; and when the frequency domain resource position of the second cell where the terminal equipment is located is equal to the second threshold, the value of the second time interval is the fifth value or the sixth value. For example, the second threshold may be 6 Ghz. The cell where the terminal equipment is located is a second cell, and when the frequency domain resource position of the second cell is greater than or equal to 6Ghz, the second cell is located at a high-frequency point, and at the moment, the terminal equipment needs to perform beam management; and when the second frequency domain resource position is less than 6Ghz, the second cell is located at the low-frequency point, and the terminal equipment does not need to perform beam management. At this time, the fifth value may be greater than the sixth value, so that the terminal device has enough time to perform the beam management operation.
In a possible design, when the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to the second threshold and the length of the second DRX cycle is greater than or equal to the first threshold, the value of the second time interval is a seventh value; the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to a second threshold, and the value of the second time interval is an eighth value when the length of the second DRX period is less than or equal to the first threshold; the frequency domain resource position of a second cell where the terminal device is located is less than or equal to a second threshold, and the value of the second time interval is a ninth value when the length of the second DRX period is greater than or equal to the first threshold; and when the frequency domain resource position of the second cell in which the terminal device is located is less than or equal to the second threshold and the length of the second DRX period is less than or equal to the first threshold, the value of the second time interval is the tenth value. The seventh value and the eighth value can refer to the description in the embodiment shown in fig. 6, and are not described herein again. The ninth value and the tenth value can refer to the description in the embodiment shown in fig. 6, and are not described herein again.
For example, the first threshold may be determined according to a time threshold for the terminal device to maintain time-frequency synchronization. For example, the first threshold may be equal to a time threshold at which the terminal device is able to maintain time-frequency synchronization. The second threshold may be 6 Ghz. When the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to 6Ghz and the length of the second DRX cycle is greater than or equal to the first threshold, the value of the second time interval is a seventh value, and at this time, the terminal device needs to perform beam management and time-frequency synchronization operation; when the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to 6Ghz and the length of the second DRX cycle is less than or equal to the first threshold, the value of the second time interval is an eighth value, and at this time, the terminal device needs to perform beam management but may not perform time-frequency synchronization operation; therefore, the seventh value may be larger than the eighth value, that is, when the terminal device needs to perform the beam management and the time-frequency synchronization operation, the second time interval may be set to be larger, and when the terminal device performs the beam management but does not perform the time-frequency synchronization operation, the second time interval may be set to be smaller. When the frequency domain resource position of the second cell where the terminal device is located is less than or equal to 6Ghz and the length of the second DRX cycle is greater than or equal to the first threshold, the value of the second time interval is a ninth value, and at this time, the terminal device needs to perform time-frequency synchronization operation without beam management; the value of the second time interval is a tenth value when the frequency domain resource position of the second cell where the terminal device is located is less than or equal to 6Ghz and the length of the second DRX period is less than or equal to the first threshold; at this time, the terminal device may perform neither time-frequency synchronization operation nor beam management. Therefore, the seventh value may be larger than the eighth value, that is, when the terminal device needs to perform time-frequency synchronization operation, the second time interval may be set to be larger, and when the terminal device does not need to perform beam management, the second time interval may be set to be smaller.
In a possible design, the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to a second threshold, and when the second DRX cycle is the first cycle, the value of the second time interval is an eleventh value; the frequency domain resource position of a second cell where the terminal device is located is less than or equal to a second threshold, and when the second DRX period is the first period, the value of the second time interval is a twelfth value; the frequency domain resource position of a second cell where the terminal device is located is greater than or equal to a second threshold, and when the second DRX period is a second period, the value of the second time interval is a thirteenth value; and when the frequency domain resource position of the second cell where the terminal device is located is less than or equal to the second threshold and the second DRX cycle is the second cycle, the value of the second time interval is a fourteenth value. The eleventh value and the twelfth value can refer to the description in the embodiment shown in fig. 6, and are not described herein again. The thirteenth value and the fourteenth value refer to the description in the embodiment shown in fig. 6, and are not described herein again.
For example, assume that the first period is a long C-DRX period configured by the network device and the second period is a short C-DRX period configured by the network device, and the second threshold is 6 Ghz. When the frequency domain resource position of the second cell where the terminal device is located is greater than or equal to 6Ghz and the second DRX cycle is the long C-DRX cycle, the value of the second time interval is the eleventh value, and at this time, the terminal device needs to perform beam management and time-frequency synchronization operation; and when the frequency domain resource position of the second cell in which the terminal equipment is located is less than or equal to 6Ghz and the second DRX period is the long C-DRX period, the value of the second time interval is a twelfth value, and at this time, the terminal equipment needs to perform time-frequency synchronization operation but may not perform beam management. Therefore, the eleventh value may be larger than the twelfth value, that is, when the terminal device needs to perform the beam management and the time-frequency synchronization operation, the second time interval may be set to be larger, and when the terminal device performs the time-frequency synchronization operation without performing the beam management, the second time interval may be set to be smaller. The frequency domain resource position of a second cell where the terminal equipment is located is more than or equal to 6Ghz, and when the second DRX period is a short C-DRX period, the value of the second time interval is a thirteenth value, and at this time, the terminal equipment needs to perform beam management without performing time-frequency synchronization operation; and when the frequency domain resource position of the second cell where the terminal equipment is located is less than or equal to 6Ghz and the second DRX period is the short C-DRX period, the value of the second time interval is a fourteenth value, and at this time, the terminal equipment can not perform time-frequency synchronization operation nor beam management. Therefore, the thirteenth value may be greater than the fourteenth value, that is, when the terminal device needs to perform beam management, the second time interval may be set to be larger, and when the terminal device does not need to perform time-frequency synchronization operation, the second time interval may be set to be smaller.
In step 1007, the terminal device receives a second signal from the network device at a second time.
When the second signal is used for indicating that the terminal device is in the sleep state in the second time interval, the terminal device enters the sleep state at the start position of the second time interval, and the terminal device can be in the sleep state until the second time interval is finished without following a C-DRX mechanism in the second time interval, so that the power consumption of the terminal device is saved. Of course, if the terminal device is in the sleep state in the second time interval, the network device instructs the terminal device to wake up from the sleep state, and the terminal device may wake up from the sleep state. After the terminal device wakes up, the C-DRX mechanism may continue to be followed.
In step 1008, the terminal device remains in the sleep state or the awake state for a second time interval according to the second signal.
The terminal equipment is in the sleep state and comprises at least one of the following items: the terminal equipment does not monitor a Physical Downlink Control Channel (PDCCH); the terminal equipment does not receive the downlink reference signal sent by the network equipment; the terminal device does not make measurements. The terminal equipment is in the wake-up state and comprises at least one of the following items: terminal equipment monitors a Physical Downlink Control Channel (PDCCH); the terminal equipment receives a downlink reference signal sent by the network equipment; and the terminal equipment performs measurement. Specifically, reference may be made to the description in the embodiment shown in fig. 6, which is not repeated herein.
In the following, the signal transmission method provided by the embodiment of the present application is introduced by taking a network device as the base station 100 and a terminal device as the mobile phone 200 as an example, in combination with the application scenarios and beneficial effects of the embodiment of the present application.
As shown in fig. 11, to save power consumption of the handset 200 or to wake up the handset 200, the base station 100 generates a first signal that may be used to indicate that the handset 200 is in a sleep state or an awake state for one or more C-DRX cycles. The base station 100 determines the starting time of the start duration of the next C-DRX cycle (upcoming C-DRX cycle) of the handset 200 and determines a first time earlier than the starting time. The first time and the starting time have a first time interval therebetween. The value of the first time interval may be selected from a plurality of values of the first time intervals pre-stored in the base station 100. When the base station determines that the current handset 200 is currently in the long C-DRX cycle, it may determine that the value of the first time interval is offset02, where offset02 corresponds to the long C-DRX cycle. The base station 100 transmits the first signal at the first time, and the handset 200 receives the first signal at the first time. Handset 200 may perform time-frequency synchronization, CSI measurement, and/or beam management operations within offset 02.
The base station 100 may then generate a second signal that may be used to indicate that the handset 200 is in a sleep state or an awake state for one or more C-DRX cycles. The base station 100 determines the start time of the start duration of the next C-DRX cycle (upcoming C-DRX cycle) of the handset 200 and determines a second time earlier than the start time. The second time and the starting time have a second time interval therebetween. The value of the second time interval may be selected from a plurality of values of the second time intervals pre-stored in the base station 100. When the base station determines that the current handset 200 is currently in the short C-DRX cycle, it may determine that the value of the second time interval is offset03, where offset03 corresponds to the short C-DRX cycle. The base station 100 transmits the second signal at the second time, and the handset 200 receives the second signal at the second time. Handset 200 may perform CSI measurements and/or beam management operations within offset 03.
The above example has been described in terms of a correspondence relationship between a value of the first time interval and a length of the C-DRX cycle, and a correspondence relationship between a value of the second time interval and a length of the C-DRX cycle, but the present application is not limited thereto, and a value of the first time interval may have a correspondence relationship with a frequency domain resource location of a cell in which the terminal device is located, or a value of the first time interval may have a correspondence relationship with both a length of the C-DRX cycle and a frequency domain resource location of a cell in which the terminal device is located. The value of the second time interval may have a corresponding relationship with the frequency domain resource location of the cell in which the terminal device is located, or the value of the second time interval may have a corresponding relationship with both the length of the C-DRX cycle and the frequency domain resource location of the cell in which the terminal device is located, and related descriptions may refer to the contents in the embodiments shown in fig. 6 and fig. 10, which are not repeated herein.
Based on the method provided by the embodiment of the application, the network device sends a first signal to the terminal device at a first time to indicate that the terminal device is in a sleep state or an awake state in a first time interval, and a first time interval is formed between the first time and the starting time of the first time interval. The value of the first time interval is not a fixed value, and can have various values, so that different processing requirements of the terminal equipment can be met. And then, the network device sends a second signal to the terminal device at a second time to indicate that the terminal device is in a sleep state or an awake state in a second time interval, and a second time interval is formed between the second time and the starting time of the second time interval. The value of the second time interval is not a fixed value, and can have various values, so that different processing requirements of the terminal equipment can be met.
The different processing requirements of the terminal device mean that the terminal device needs to perform partial or all of the time-frequency synchronization, CSI measurement, beam management and other processing in the first time interval or the second time interval under different conditions, and the more the processing is performed, the longer the required time is. In the method provided by the embodiment of the application, the first time interval or the second time interval may have a plurality of values (i.e., a plurality of lengths), and may correspond to different processing requirements of the terminal device. For example, when the terminal device needs to perform time-frequency synchronization at the first time interval, the value of the first time interval can be set to be larger, and when the terminal device does not need to perform time-frequency synchronization at the second time interval, the value of the second time interval can be set to be smaller, so that different requirements of the terminal device can be met, and power consumption waste is avoided.
