Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In 4G and 5G communication systems, a terminal in a Radio Resource control (RRC _ idle) layer idle state needs to detect a paging signal sent by a network device at a pre-configured time, where the specific paging signal process is as follows: blind detecting a PDCCH (physical downlink control channel) corresponding to a Paging Radio Network temporary identity (P-RNTI), and if the PDCCH is not detected, ending the detection; if the presence of the PDCCH is detected, a Physical Downlink Shared Channel (PDSCH) indicated by the PDCCH is further detected, and if the detected PDSCH is not a paging signal of the terminal, the detection is terminated. In the RRC _ idle state, the terminal periodically detects paging signals, and the power consumption of detecting the PDCCH or PDSCH each time is large, but the probability of detecting paging signals belonging to the terminal is low, which is not favorable for the terminal to save power.
In a Discontinuous Reception (DRX) scenario, the basic mechanism of DRX is: a terminal in a connected (RRC _ connected) state is configured with a DRX cycle (cycle), as shown in fig. 1, fig. 1 shows a time domain diagram of the DRX cycle, where the DRX cycle includes an active period (On Duration) in which the terminal monitors and receives a PDCCH, and a dormant period (opportunity for DRX) in which the terminal does not receive data of a downlink channel to save power consumption. That is, in the time domain, time is divided into successive DRX cycles. Wherein, the DRX start offset (drxStartOffset) is used to indicate the start subframe of the DRX Cycle, and the long DRX Cycle (long DRX-Cycle) is used to indicate how many subframes the long DRX Cycle occupies. Where both parameters are determined by the longDRX-CycleStartOffset field. The active period Timer (On Duration Timer) specifies the number of consecutive subframes (i.e., the number of subframes for which the active period lasts) for which monitoring of the PDCCH is required from the starting subframe of the DRX cycle.
In most cases, after a terminal is scheduled to receive or transmit data in a certain subframe, it is likely to continue to be scheduled in the next several subframes, and if it waits for the next DRX cycle to receive or transmit, the data will cause extra delay. To reduce such delay, the terminal may continue to be in the active period after being scheduled, i.e., may continue to monitor the PDCCH during the configured active period. Specifically, when the terminal is scheduled to initially transmit data, a deactivation timer (drx-inactivity timer) is started or restarted, and the terminal is always in an active period during the time that the timer is not expired. The drx-inactivity timer specifies the number of consecutive subframes that are continuously in an active state after the terminal successfully decodes a PDCCH indicating Uplink (UL) or Downlink (DL) user data to be transmitted first. I.e. the timer is restarted once each time the terminal has the initial data to be transmitted scheduled.
An embodiment of the present invention provides an information transmission method, which is applied to a network device, and as shown in fig. 2, the method includes the following steps:
step 21: configuring a target transmission resource for the early indication signal.
Wherein the advance indication signal includes: at least one of a wake signal WUS and a sleep signal GTS. The bandwidth occupied by the target transmission resource is less than or equal to the bandwidth occupied by the synchronization signal block SSB. Wherein, a synchronization signal Block (SS Block) occupies 20 Resource Blocks (RB), and 20 RBs occupy a bandwidth of 3.6MHz in total at Sub-carrier Spacing (SCS) of 15 KHz; for an early indication signal, such as the wake up signal WUS, the occupied bandwidth may be narrower, such as one RB. For example, the target transmission resource configured by the network device for the early indication signal occupies a bandwidth of one RB (e.g., 180KHz), and the bandwidth of the target transmission resource is smaller than that of the SS Block. Or, the network device occupies a bandwidth of 20 RBs (180KHz × 20) for the target transmission resource configured for the advance indication signal, and the bandwidth occupied by the target transmission resource is 3.6MHz, which is the same as the bandwidth occupied by the SS Block.
Wherein, SS Block includes: primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH). The above SS Block is also called SS/PBCH Block. The terminal and a cell perform synchronization (including time synchronization and frequency synchronization) and acquire a corresponding timing relationship, where the timing relationship includes a subframe Number (subframe Number) and a System Frame Number (SFN). When a specific SS Block of the cell needs to be read (e.g., the SS Block is associated with an RMSI and/or OSI, etc.), the specific SS Block is called a cell-defining SS Block.
In order to further save the power consumption of blind detection Paging signal or PDCCH in DRX scenario, concepts of WUS and GTS are proposed, wherein WUS and GTS are collectively referred to as advance indication signal. In each DRX period of an idle state or an RRC connected state or in the RRC connected state (DRX OFF), before the terminal blindly detects a Paging signal or a PDCCH, the network equipment firstly transmits a WUS to the terminal, and the terminal wakes up at the corresponding moment to detect the WUS. If the terminal detects the WUS, the terminal blindly detects a Paging signal or a PDCCH; otherwise, the terminal does not blindly detect the Paging signal or the PDCCH and continues to sleep. As shown in fig. 3, when the network device configures a WUS for the terminal, the terminal may detect the WUS on a physical channel, determine that PDCCH detection is required in the next DRX cycle if the WUS is detected, and determine that PDCCH detection is not required in the next DRX cycle if the WUS is not detected, and continue to maintain the sleep state. Alternatively, in each DRX cycle of the idle state or the RRCconnected state, the network device may further transmit a GTS to the terminal before the terminal blindly detects the Paging signal or the PDCCH, and the terminal wakes up to detect the GTS at a corresponding time. If the terminal detects the GTS, the terminal does not blindly detect the Paging signal or the PDCCH and continues to sleep; otherwise, the terminal blindly detects the Paging signal or the PDCCH. Among them, detecting WUS or GTS is less complex and more power efficient than blindly detecting Paging signals or PDCCH.
Further, the current designs of the early indication signals (including WUS or GTS) include the following: OOK (on-off keying), sequence (with or without DTX), channel coded payload (payload) such as PDCCH, etc., sequence + payload (e.g., receiving sequence to complete synchronization, and then receiving payload in a synchronized state).
Here, taking the sequence as an example, the early indication signal may be transmitted discontinuously (with DTX) or without discontinuous transmission (without DTX). Taking the with DTX as an example: when the early indication signal bears the WUS sequence, if the terminal detects the WUS sequence, the terminal determines that PDCCH detection is needed in the next DRX period, and if the WUS sequence is not detected, the terminal determines that the PDCCH is not needed in the next DRX period. Similarly, when the early indication signal carries the GTS sequence, if the GTS sequence is not detected, it is determined that PDCCH detection is required in the next DRX cycle, and if the GTS sequence is detected, it is determined that PDCCH detection is not required in the next DRX cycle. Take without DTX as an example: when the WUS sequence is carried by the early indication signal, if the WUS sequence is detected to be in a first sequence format, the corresponding PDCCH is determined to be required to be detected in the next DRX period, and if the WUS sequence is detected to be in a second sequence format, the corresponding PDCCH is determined not to be required to be detected in the next DRX period, and the terminal continues to sleep. Similarly, when the early indication signal carries the GTS sequence, if it is detected that the GTS sequence is in the third sequence format, it is determined that the corresponding PDCCH needs to be detected in the next DRX cycle, and if it is detected that the GTS sequence is in the fourth sequence format, it is determined that the corresponding PDCCH does not need to be detected in the next DRX cycle, and the terminal continues to sleep.
Step 22: and sending an advance indication signal to the terminal through the target transmission resource.
The network equipment sends an advance indication signal to the terminal on the target transmission resource. Wherein the target transmission resource occupies a frequency domain resource of at least one RB, the frequency domain resource including: bandwidth, bandwidth portion or channel, etc. The frequency domain location may be predefined, configured or reconfigured by the network device, or determined by the network device from a calculation of the terminal's identification information (UE ID).
The target transmission resource is determined by calculation according to the UE ID of the terminal, specifically: mapping the UE ID to N groups of downlink BWPs through a Hash function; the UE ID includes an International Mobile Subscriber Identity (IMSI), a Packet-Temporary Mobile subscriber identifier (P-TMS), a user Temporary identifier (TMS), or a short format; wherein the N groups of downstream BWPs are protocol predefined or network device configured.
In a preferred embodiment, the frequency domain location of the target transmission resource is within any of the following ranges:
frequency domain resources outside the system bandwidth range, i.e. the frequency domain position of the target transmission resource is outside the system bandwidth (out-band);
frequency domain resources within the system bandwidth range, i.e. the frequency domain position of the target transmission resource is located within the system bandwidth (in-band);
frequency domain resources within the protection bandwidth range of the system bandwidth, i.e. the frequency domain position of the target transmission resource is located in the protection bandwidth (guard-band) of the system bandwidth; this may save frequency resources.
The frequency domain resource outside the initial Downlink Bandwidth Part (initial DL BWP) range, i.e. the frequency domain position of the target transmission resource, is located outside the initial Downlink BWP (initial DL BWP) (out-band). The bandwidth of a Control Resource Set (CORESET) of Remaining Minimum System Information (RMSI) in the 5G system is an initial downlink bandwidth part, and the RMSI CORESET is indicated by a Master Information Block (MIB). In addition, in order to save power in the 5G system, the terminal may operate at a relatively small operating Bandwidth (e.g. 5MHz), and one cell of the network device may configure a relatively large system Bandwidth (e.g. 100MHz), and the small Bandwidth portion of the large Bandwidth where the terminal operates is regarded as a Bandwidth portion (BWP), although the BWP may also be configured as the whole system Bandwidth. The network device may configure 1 or more BWPs for the terminal and transform the BWP in which the terminal operates by activating or deactivating the BWPs.
The frequency domain resource in the initial downlink bandwidth part range, that is, the frequency domain position of the target transmission resource, is located in the initial downlink BWP (in-band);
the frequency domain resource occupied by the synchronization signal block is out of the bandwidth range, that is, the frequency domain position of the target transmission resource is positioned out of the occupied bandwidth (out-band) of the synchronization signal and the physical broadcast channel;
the frequency domain resource occupied by the synchronization signal block, i.e. the frequency domain position of the target transmission resource, is located in the occupied bandwidth (in-band) of the synchronization signal and the physical broadcast channel.
In another preferred embodiment, the center frequency point of the target transmission resource is one of the following:
the central frequency point of the bandwidth occupied by the synchronous signal Block, namely the central frequency point of the target transmission resource is consistent with the central frequency point of the bandwidth occupied by the SS Block; if the terminal needs to switch to a wider BWP for synchronization, the Radio frequency tuning (RF tuning) time of the terminal may be shorter because the center frequency point of the target transmission resource is consistent with the center frequency point of the bandwidth occupied by SS Block.
The central frequency point of the initial downlink bandwidth part, namely the central frequency point of the target transmission resource is consistent with the central frequency point of the bandwidth where the initial downlink BWP is located;
the central frequency point of the bandwidth where the control resource set of the remaining minimum system information is located, that is, the central frequency point of the target transmission resource is consistent with the central frequency point of the bandwidth where the RMSI CORESET is located. If the UE needs to switch to a wider BWP for receiving the system message, the rftuning time of the UE may be shorter because the center frequency of the target transmission resource is consistent with the center frequency of the bandwidth where the RMSI core is located.
Further, step 22 may be implemented by a dedicated transmitter, that is, the network device sends the advance indication signal to the terminal by carrying the advance indication signal on the target transmission resource through the dedicated transmitter. Wherein the network device comprises a main transmitter and a dedicated transmitter, wherein the dedicated transmitter is used for exclusively transmitting the advance indication signal, and the system bandwidth or radio frequency bandwidth of the dedicated transmitter is narrower than the system bandwidth or radio frequency bandwidth of the main transmitter.
In a preferred embodiment, step 22 comprises: transmitting an advance indication signal and at least one of the following to the terminal through the target transmission resource: a Synchronization Signal (SS), a physical broadcast Channel PBCH, remaining minimum System Information RMSI, Other System Information (OSI), a Channel State indication Reference Signal (CSI-RS), and a paging message. That is, the network device transmits at least one of SS, PBCH, RMSI, OSI, CSI-RS, and paging to the terminal by indicating in advance a target transmission resource in which the signal is located.
Similarly, the step of sending the advance indication signal and the other signals to the terminal may also be implemented by a dedicated transmitter, that is, the advance indication signal and at least one of the following signals are sent to the terminal by the dedicated transmitter: synchronization signals, physical broadcast channels, remaining minimum system information, other system information, channel state indication reference signals, and paging messages. Preferably, the network device may further carry the early indication signal in combination with at least one of SS, PBCH, RMSI, OSI, CSI-RS, and paging in the target transmission resource via a dedicated transmitter to the terminal, i.e., the network device sends the early indication signal on the target transmission resource via a separate dedicated transmitter, and at least one of SS, PBCH, RMSI, OSI, CSI-RS, and paging, where it is noted that the SS, PBCH, RMSI, OSI, CSI-RS, and paging need to be redesigned to adapt to the system bandwidth of the dedicated transmitter. On the other hand, the advance indication signal and the transmission beam of at least one of the SS, PBCH, RMSI, OSI, CSI-RS, and paging may be an omni-directional beam.
In the information transmission method of the embodiment of the invention, the network equipment configures a target transmission resource with the same or narrower frequency band as the SSB for the early indication signal and transmits the early indication signal through the target transmission, so that the terminal detects the early indication signal on the target transmission resource, thereby reducing the detection complexity and the detection power consumption of the terminal.

The network device in the embodiment of the invention configures a target transmission resource with the same or narrower frequency band as the SSB for the early indication signal, and transmits the early indication signal through the target transmission, so that the terminal detects the early indication signal on the target transmission resource, thereby reducing the detection complexity and the detection power consumption of the terminal.
The above embodiment describes the information transmission method of the present invention from the network device side, and the following embodiment further describes the information transmission method at the terminal side with reference to the drawings.
As shown in fig. 6, the information transmission method according to the embodiment of the present invention is applied to a terminal, and includes the following steps:
step 61: and determining the target transmission resource configured for the advance indication signal by the network equipment.
Wherein the advance indication signal includes: at least one of a wake signal WUS and a sleep signal GTS. The bandwidth occupied by the target transmission resource is less than or equal to the bandwidth occupied by the synchronization signal block SSB.
Step 62: an advance indication signal is received over the target transmission resource.
The terminal receives the advanced indication signal through a target transmission resource, wherein the target transmission resource occupies a frequency domain resource of at least one RB, and the frequency domain resource comprises: bandwidth, bandwidth portion or channel, etc. The frequency domain location may be predefined, configured or reconfigured by the network device, or determined by the network device from a calculation of the terminal's identification information (UE ID).
Preferably, the terminal receives a target transmission resource occupying a bandwidth (or bandwidth part BWP, or channel, or frequency domain resource) of one RB (e.g. 180KHz) configured by the network device for receiving a WUS (wake-up signal).
Alternatively, the protocol predefines a target transmission resource of bandwidth (or bandwidth part BWP, or channel, or frequency domain resource) of one RB (180KHz) for receiving a WUS (wake-up signal);
alternatively, the terminal determines a target transmission resource for receiving a WUS (wake-up signal) based on its UE ID, the target transmission resource being a bandwidth (or bandwidth part BWP, or channel, or frequency domain resource) occupying one RB (180 KHz). Specifically, the terminal maps the UE ID to N groups of downlink BWPs through a hash function; the UE ID includes IMSI, P-TMS, or short format. Wherein the N groups of downstream BWPs are protocol predefined or network device configured.
Wherein, the frequency domain position of the target transmission resource is located in any one of the following ranges: frequency domain resources outside the system bandwidth range; frequency domain resources within a system bandwidth range; frequency domain resources within a guard bandwidth range of a system bandwidth; frequency domain resources outside the range of the initial downlink bandwidth part; initiating frequency domain resources within a downlink bandwidth part range; the frequency domain resources outside the bandwidth range occupied by the synchronous signal block; the synchronization signal block occupies the frequency domain resource within the bandwidth range. It is worth pointing out that the foregoing embodiments of the network device side have described possible ranges of frequency domain positions, and are not described herein again to avoid repetition.
The center frequency point of the target transmission resource is one of the following: the central frequency point of the bandwidth occupied by the synchronous signal block; a central frequency point of an initial downlink bandwidth part; and the center frequency point of the bandwidth where the control resource set of the residual minimum system information is located. It is worth pointing out that, in the above-mentioned embodiment of the network device side, the central frequency point of the target transmission resource has been introduced, and details are not described herein again to avoid repetition.
Preferably, step 62 may be implemented by a dedicated receiver, i.e. the terminal receives the early indication signal carried on the target transmission resource through the dedicated receiver. Wherein the terminal comprises a main receiver and a special receiver. The special receiver is used for specially receiving the advance indication signal, and the system bandwidth or the radio frequency bandwidth of the special receiver is narrower than the system bandwidth or the radio frequency bandwidth of the main receiver so as to save the energy consumption of the terminal.
In a preferred embodiment, step 61 is followed by: receiving, over a transmission resource different from the target transmission resource, at least one of: synchronization signals, physical broadcast channels, remaining minimum system information, other system information, channel state indication reference signals, and paging messages. That is, the terminal receives or detects at least one of the first SS, the first PBCH, the first RMSI, the first OSI, the first CSI-RS, and the first paging on a transmission resource different from the target transmission resource. The first SS, the first PBCH, the first RMSI, the first OSI, the first CSI-RS and the first paging are the existing SS, PBCH, RMSIOSICSI-RS and paging.
In this case, the terminal performs synchronization or measurement through the SSB, and reads a system message according to PBCH or a System Information Block (SIB); at this time, the terminal that has detected the WUS needs RF tuning (tuning) to the transmission resource of the SSB to complete synchronization and reading the MIB, and needs RF tuning to the transmission resource of the RMSICORESET to read the RMSI, OSI, paging, and the like.
Optionally, the step of receiving the synchronization signal through a transmission resource different from the target transmission resource includes: performing downlink synchronization according to the synchronization signal and a preset period; wherein, the preset period is greater than the transmission period of the advance indication signal, or the preset period is greater than the discontinuous reception DRX period (cycle). Namely, the terminal carries out downlink synchronization with the first SS according to a preset period; the preset period is greater than the DRX cycle or greater than a period of receiving an advance indication signal (e.g., WUS).
In another embodiment, step 62 comprises: receiving, by the target transmission resource, an advance indication signal and at least one of: synchronization signals, physical broadcast channels, remaining minimum system information, other system information, channel state indication reference signals, and paging messages. That is, the network device transmits at least one of SS, PBCH, RMSI, OSI, CSI-RS, and paging to the terminal by indicating in advance a target transmission resource in which the signal is located. In this way, the terminal receives or detects at least one of the second SS, the second PBCH, the second RMSI, the second OSI, the second CSI-RS, and the second paging on the target transmission resource. Wherein the second SS, the second PBCH, the second RMSI, the second OSI, the second CSI-RS and the second paging are new SS, PBCH, RMSI, OSI, CSI-RS and paging adapting the target transmission resource of the early indication signal. The terminal performs synchronization or measurement through a new SS transmitted on the target transmission resource, and reads a system message through a new PBCH or SIB transmitted on the target transmission resource. It should be noted that the terminal does not need to perform RF tuning after detecting the WUS.
Similarly, the step of receiving the early indication signal and at least one of the following may be implemented by the target transmission resource: receiving, by a dedicated receiver, an advance indication signal and at least one of: synchronization signals, physical broadcast channels, remaining minimum system information, other system information, channel state indication reference signals, and paging messages. That is, the terminal may also receive the advance indication signal and at least one of the SS, PBCH, RMSI, OSI, CSI-RS, and paging through a dedicated receiver. That is, the terminal detects or receives the early indication signal and at least one of SS, PBCH, RMSI, OSI, CSI-RS, and paging on the target transmission resource through a separate dedicated receiver. Wherein the advance indication signal and the receive beam of at least one of the SS, PBCH, RMSI, OSI, CSI-RS, and paging may be an omni-directional beam. It is worth pointing out that in this scenario, the primary receiver can be completely turned off to save terminal power consumption. The main receiver is used for receiving signals except the early indication signal and the second SS, the second PBCH, the second RMSI, the second OSI, the second CSI-RS and the second paging, and can be turned on as required.
In another preferred embodiment, the receiving the remaining minimum system information or other system information via the target transmission resource further comprises: acquiring a first transmission resource according to the residual minimum system information or other system information; performing radio measurement and cell reselection on the first transmission resource; the first transmission resource is a frequency domain resource configured by a neighboring cell, and is used for transmitting an advance indication signal. Preferably, the first transmission resource is further for transmitting at least one of: synchronization signals, physical broadcast channels, remaining minimum system information, other system information, channel state indication reference signals, and paging messages. Preferably, the first transmission resource is narrower than or consistent with the SSB transmission bandwidth of the neighboring cell; the first transmission resource is configured and issued by the network equipment. That is, the cell reselection of the terminal is completed by the first transmission resource working in the target cell; optionally, the network device notifies the terminal of the first transmission resource of the target cell.
Preferably, the terminal may be equipped with two crystal oscillators: RTC and LO XO, both have the difference in cost performance, and XO performance is better than RTC. The terminal equipped with the RTC and the XO at the same time can only turn on the RTC when operating in idle mode for further power saving. In order to distinguish the capabilities of different terminals, the terminal may report the crystal oscillator capability (in idle state), and optionally, the UE may update (update) the capability and report the capability to the network device again. The network equipment receives the crystal oscillator capacity reported by the terminal; sending a reference signal to the terminal according to the crystal oscillator capacity and/or the moving speed of the terminal; and sends a sequence for synchronization every N DRX cycles. Correspondingly, the terminal reports the crystal oscillation capacity, wherein the synchronous behavior of the terminal is related to the reported crystal oscillation capacity; the terminal performs synchronization once through SSS every N DRX cycles, or performs synchronization once through SSS if x DRX cycles do not detect the advance indication signal.
Wherein, after the UE enters a new Tracking Area (TA), the crystal oscillation capability is reported again. The specific report may be indicated by 1bit, for example, indicating RTC when the value of the bit is 0, and indicating LO XO when the value of the bit is 1.
Or when the value of the bit is 0, the terminal is indicated to be synchronized for at least x milliseconds once, and when the value of the bit is 1, the terminal is indicated to be synchronized for at least y milliseconds once; wherein x, y > 0.
Or, when the value of the bit is 0, indicating that: the maximum frequency tolerance (max frequency error) is M ppm, and a value of 1 for this bit indicates: max frequency error is N ppm, where M, N > 0.
Or, when the value of the bit is 0, the network device is instructed to send the sequence for synchronization every x1 milliseconds, and when the value of the bit is 1, the network device is instructed to send the sequence for synchronization every y1 milliseconds, wherein x1 and y1> 0.
In the information transmission method of the embodiment of the invention, the terminal determines that the network equipment configures a target transmission resource with the same or narrower frequency band as the SSB for the advance indication signal, and detects the advance indication signal through the target transmission, so that the detection complexity and the detection power consumption of the terminal can be reduced.
