Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, a terminal, and a network device.

Background technique

In the fourth generation (4 ^th Generation, 4G) and fifth generation (5 ^th Generation, 5G) communication system, discontinuous reception (Discontinuous Reception, DRX) scenario, which is the basic mechanism of the DRX: is in the connected The terminal in the (RRC_connected) state configures a DRX cycle. As shown in FIG. 1, FIG. 1 shows a time domain diagram of a DRX cycle, which includes an On Duration and an Opportunity for DRX. During the activation period, the terminal monitors and receives the PDCCH, and the terminal does not receive the downlink channel data during the sleep period to save power consumption. In most cases, when a terminal is scheduled and receives or transmits data in a certain subframe, it is likely to continue to be scheduled in the next few subframes. If it waits until the next DRX cycle to receive or transmit, the data is received. Will bring additional delay. In order to reduce such delays, the terminal will remain in the active period after being scheduled. Specifically, when the terminal is scheduled to transmit data, a timer is started or restarted, and the terminal is always in an active period during the timeout period of the timer.

In order to further reduce the power consumption of the blind detection paging (Paging) signal or the physical downlink control channel (Physical Downlink Control Channel, PDCCH) in the discontinuous reception (DRX) scenario, a wake-up signal (Wake-Up Signal) is proposed. , WUS) and the concept of Go To Sleep Signal (GTS), detecting WUS or GTS is less complex and more power efficient than blind detection of Paging signals or PDCCH. The 5G system, or New Radio (NR) system, is a multi-beam transmission system. For receiving signals, it is necessary to receive based on the preferred receiving beam to obtain better receiving performance. In order to ensure that the signal transmission between the network device and the terminal is transmitted on a beam of better quality, the network device and the terminal need to transmit and receive signals through the transmission and reception of the control signal to maintain an optimal beam, and the terminal is in DRX or idle. In the (idle) state, the signal will not be received for a long time. When the next time the reception is turned on, it is very likely that the signal transmission between the terminal and the network device cannot be performed on the optimal beam, thereby affecting the reception of the reception start time signal. performance. If you want to ensure better reception performance during the activation period or paging opportunity (Paging Occasion, PO) of DRX, you need to determine the optimal receiving beam. If the terminal wakes up frequently for beam training, the complexity is high and the terminal consumes more power. .

detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a particular order or order. It is to be understood that the data so used may be interchanged where appropriate, such that the embodiments of the present application described herein can be implemented, for example, in a sequence other than those illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices. "An item of A, B, and C" and "A, B, or C" are intended to include any of A, B, and C.

The terminal in the radio resource control idle state (RRC_idle) of the 4G and 5G communication systems needs to detect the paging signal sent by the network device at a pre-configured time. The specific paging signal process is as follows: blind Detecting a PDCCH corresponding to a Paging Radio Network Temporary Identity (P-RNTI), if the PDCCH is not detected, ending the current detection; if detecting the PDCCH, detecting the physical downlink indicated by the PDCCH The physical downlink link (Physical Downlink Share Channel, PDSCH) ends the detection if the detected PDSCH is not the paging signal of the terminal. Otherwise, the detected PDSCH is the paging signal of the terminal. In the RRC_idle state, the terminal periodically detects the paging signal, and the power consumption of detecting the PDCCH or the PDSCH is large each time, but the probability of detecting the paging signal belonging to itself is low, which is disadvantageous for the terminal to save power. Those skilled in the art will appreciate that the 4G and 5G communication systems are merely illustrative, and the scope of the disclosure is not limited to a particular communication system.

In the DRX scenario, the basic mechanism of the DRX is to configure a DRX cycle for the terminal in the RRC_connected state, including an activation period and a sleep period. During the activation period, the terminal monitors and receives the PDCCH during sleep. During the period, the terminal does not receive data of the downlink channel to save power consumption. That is to say, in the time domain, time is divided into consecutive DRX cycles. The DRX start offset (drxStartOffset) is used to indicate the start subframe of the DRX cycle, and the long DRX-Cycle is used to indicate how many subframes the long DRX cycle occupies. Among them, these two parameters are determined by the longDRX-CycleStartOffset field. The On Duration Timer specifies the number of consecutive subframes that need to be monitored from the starting subframe of the DRX cycle (ie, the number of subframes in which the active period lasts).

In most cases, when a terminal is scheduled and receives or transmits data in a certain subframe, it is likely to continue to be scheduled in the next few subframes. If it waits until the next DRX cycle to receive or transmit, the data is received. Will bring additional delay. In order to reduce such delay, the terminal will continue to be in the active period after being scheduled, that is, the PDCCH will be continuously monitored during the configured activation period. Specifically, when the terminal is scheduled to transmit data, a deactivation timer (drx-InactivityTimer) is started or restarted, and the terminal is always in an active period during the period when the timer is not timed out. The drx-inactivityTimer specifies the number of consecutive subframes that continue to be in the active state after the terminal successfully decodes a PDCCH indicating the initial uplink (UL) or downlink (DL) user data. That is, whenever the terminal has initial data to be scheduled, the timer is restarted once.

In order to further save the power consumption of the blind detection Paging signal or PDCCH in the DRX scenario, the concepts of WUS and GTS are proposed, wherein WUS and GTS are collectively referred to as an advance indication signal. The network device first transmits a WUS to the terminal, and the terminal at the corresponding moment, before the terminal detects the paging signal or the PDCCH in the LDP connected state or the RRC connected state (DRX OFF). Wake up to detect the WUS. If the terminal detects the WUS, the terminal blindly detects the Paging signal or the PDCCH; otherwise, the terminal does not blindly detect the Paging signal or the PDCCH, and continues to sleep. As shown in FIG. 2, when the network device configures the WUS for the terminal, the terminal can detect the WUS on the physical channel. If the WUS is detected, it is determined that the PDCCH detection needs to be performed in the next DRX cycle. If the WUS is not detected, the next determination is made. The PDCCH detection is not required in the DRX cycle, and the sleep state is continued. Alternatively, in each DRX cycle of the idle state or the RRC connected state, before the terminal blindly detects the Paging signal or the PDCCH, the network device may further transmit a GTS to the terminal, and the terminal wakes up to detect the GTS at the corresponding moment. 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 complicated and more power-efficient than blind detection of Paging signal or PDCCH.

Further, the design of the advance indication signal (including WUS or GTS) includes the following: OOK (on-off keying), sequence (with or without DTX), channel-encoded payload (such as PDCCH, etc.), sequence + payload (If the receiving sequence completes the synchronization, then the payload is received in the synchronized state).

For example, taking the sequence as an example, the advance indication signal may be discontinuous transmission (with DTX) or no discontinuous transmission (without DTX). Taking with DTX as an example: when the advance indication signal carries the WUS sequence, if the terminal detects the WUS sequence, it is determined that PDCCH detection needs to be performed in the next DRX cycle, and if the WUS sequence is not detected, it is determined to be in the next DRX cycle. There is no need to perform PDCCH. Similarly, when the GTS sequence is carried by the indication signal, if the GTS sequence is not detected, it is determined that the PDCCH detection needs to be performed in the next DRX cycle, and if the GTS sequence is detected, it is determined that the PDCCH detection is not required in the next DRX cycle. . For example, when the WUS sequence is in the first sequence format, it is determined that the corresponding PDCCH needs to be detected in the next DRX cycle, and if the WUS is detected as the second 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. Similarly, when the GTS sequence is in 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. If the GTS is detected as the fourth sequence format, the next one is determined. The corresponding PDCCH does not need to be detected in the DRX cycle, and the terminal continues to sleep.

An embodiment of the present disclosure provides an information transmission method, which is applied to a terminal side. As shown in FIG. 3, the method includes the following steps:

Step 31: Determine a quasi-co-location relationship between the advance indication signal and the target signal.

The advance indication signal includes at least one of a wakeup signal WUS and a sleep signal GTS. The advance indication signal may be transmitted in the form of a sequence or may be transmitted in the form of a PDCCH. In addition to indicating whether the terminal performs PDCCH/PDSCH reception, the advance indication signal may also be used to indicate whether the terminal performs Radio Resource Management (RRM) measurement or the like. If the signals of the two antenna ports satisfy the QCL relationship, the Doppler shift, the Doppler spread, the average delay, and the delay spread of the channels experienced by the two sets of signals ( At least one of the delay spread and the spatial Rx parameter is approximately the same.

It is worth noting that the target signal includes: Synchronization Signal and PBCH Block (SSB), Channel State Information Reference Signal (CSI-RS), paging opportunity PO or carried in the physical downlink channel. signal. The physical downlink channel includes: a PDCCH or a PDSCH, and the signal carried in the physical downlink control channel includes: a signal carried in the PDCCH, such as a PDCCH and a PDCCH demodulation reference signal (DMRS), and Signals in the PDSCH, such as DMRS of PDSCH and PDSCH.

The SSB is taken as an example. As shown in FIG. 4, the SSB occupies 240 REs in the frequency direction and occupies 4 OFDM symbols in the time direction, including a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (Secondary). Synchronization Signal (SSS), Physical Broadcast Channel (PBCH) signal, and DMRS of PBCH. The mapping locations of each signal within the resources of the SSB are shown in Table 1:

Table 1

among them,

Step 32: If the advance indication signal and the target signal are quasi-co-located, the advance indication signal or the target signal is received from the network device side according to the quasi co-location parameter.

Since the NR system is based on multi-beam transmission, the reception of the signal needs to be received based on the preferred reception beam to obtain better reception performance. If the advance indication signal and a target signal are Quasi Co-Location (QCL), the reception beam that is the same as the target signal of its QCL can be used for reception when receiving the advance indication signal. Similarly, if the other target signals and the advance indication signal are QCL, the target signal can be received using the same receive beam as the reception advance indication signal. That is to say, in the case of clarifying the QCL relationship between different signals, the receiving end can be conveniently determined to determine the preferred receiving beam, avoiding the complexity caused by repeated beam training, and is beneficial to the terminal to save power.

The following embodiment will introduce how the terminal determines the quasi-co-location relationship between the advance indication signal and other target signals in combination with an optional implementation.

Manner 1: Receive at least one of the following information from a network device side: system information, radio resource control RRC dedicated signaling, Media Access Control (MAC) control unit (Control Element, CE), and downlink control Downlink Control Information (DCI); determines the quasi-co-location relationship between the advance indication signal and the target signal according to the indication of the above information.

The method is an explicit indication mode, and the target signal is an SSB as an example, and the early indication signal and an SSB resource index number (index) are indicated by system information, RRC specific signaling, MAC-CE or DCI. The QCL relationship between the corresponding SSBs. Taking CSI-RS as an example, the QCL relationship between the advance indication signal and the CSI-RS corresponding to a certain CSI-RS resource index number is indicated by system information, RRC specific signaling, MAC-CE or DCI. Taking PO as an example, the system information indicates the QCL relationship between the advance indication signal and the PO. Taking the PDCCH as an example, the QCL relationship between the advance indication signal and the PDCCH to be monitored in the On duration is indicated by system information, RRC specific signaling, MAC-CE or DCI.

In this manner, the foregoing information for indicating a quasi-co-location relationship between the advance indication signal and the target signal further includes indication information for indicating a quasi co-location type, and the quasi co-location type is used to indicate the Doppler frequency offset. At least one of the Doppler spread, the average delay, the delay spread, and the spatial receive parameters are quasi-co-located. Wherein, if the information indicates that the quasi co-location type is QCL-TypeA, the Doppler frequency offset, the Doppler spread, the average delay, and the delay spread are quasi-co-located; if the information indicates that the quasi-co-location type is In QCL-TypeB, the Doppler frequency offset and Doppler spread are quasi-co-located; if the above information indicates that the quasi-co-location type is QCL-TypeC, the Doppler frequency offset and the average delay are quasi co-location. If the above information indicates that the quasi-co-location type is QCL-TypeD, the spatial receiving parameter is quasi-co-located. For example, the QCL type can be indicated by RRC dedicated signaling, that is, which parameters are QCL. If the parameters such as Doppler shift, Doppler spread, average delay, and delay spread satisfy QCL, the channel estimation of PDCCH-DMRS can be based on SSB/WUS with its QCL. The estimated delay Doppler parameters are used for channel estimation, which reduces the estimation complexity.

Optionally, the association between the WUS and the SSB (especially the non-QCL association relationship) is configured by system information or RRC dedicated signaling, and the WUS can determine the timing of the WUS with the associated SSB.

Manner 2: Determine a quasi-co-location relationship between the advance indication signal and the target signal according to the relationship between the first transmission resource and the second transmission resource. The first transmission resource is used to transmit an advance indication signal, and the second transmission resource is used to transmit a target signal.

This mode is an implicit indication method. Taking the target signal as the SSB as an example, when the time and/or frequency resource position between the advance indication signal and a certain SSB satisfies certain conditions, it is considered that the advance indication signal and the SSB satisfy the QCL relationship. Taking CSI-RS as an example, when the time and/or frequency resource position between the advance indication signal and a certain CSI-RS satisfies certain conditions, it is considered that the advance indication signal and the CSI-RS satisfy the QCL relationship. Taking PO or PDCCH as an example, when the time and/or frequency resource position between the advance indication signal and the PDCCH to be monitored in the PO/On duration satisfies certain conditions, the advance indication signal and the PO/PDCCH are considered to satisfy the QCL relationship.

Optionally, the step of determining a quasi-co-location relationship between the advance indication signal and the target signal according to the relationship between the first transmission resource and the second transmission resource, including:

When the first transmission resource and the second transmission resource are separated by a preset time interval, the advance indication signal and the target signal quasi-co-location are determined. Taking the advance indication signal as WUS and the target signal as SSB as an example, when the time interval between WUS and SSB is T1 (ms, slot slots, OFDM symbol symbols, etc.), it is determined that the QCL relationship is satisfied between the two. Taking CSI-RS as an example, when the time interval between the advance indication signal and the CSI-RS resource is T1, it is determined that the QCL relationship is satisfied between the two. Taking the PDCCH as an example, when the time interval between the advance indication signal and the PDCCH to be monitored is T1, it is determined that the two satisfy the QCL relationship.

For example, for an idle state or a C-DRX terminal, the WUS and the SSB may have a fixed time relationship. To ensure transmission performance, the WUS may be transmitted in a beam sweaping manner, that is, in different beam directions. Multiple transmissions are performed, and the transmitted beam is a set or subset of beams transmitted by the SSB. As shown in FIG. 5, there may be a fixed time offset T0 between WUS and SSB, and then the QCL relationship is satisfied between the SSBs with WUS interval T0. Or, for the idle state or the terminal in the C-DRX, the WUS and the PDCCH indicated by the WUS may be in a fixed time relationship. To ensure the transmission performance, both the WUS and the PDCCH may be sent in a beam sweaping manner, that is, in different manners. Multiple transmissions are made in the beam direction. As shown in FIG. 6, there is a time interval of T1 between the WUS and the PDCCH indicated to be monitored, and then the QCL relationship is satisfied between the PDCCH, the PDCCH-DMRS, the PDSCH, and the PDSCH-DMRS with the WUS interval T1.

Optionally, when the first transmission resource and the second transmission resource are separated by a preset time interval, the step of determining the advance indication signal and the target signal quasi-co-location includes: before or after the first transmission resource is located in the second transmission resource When the Nth time window is within, the advance indication signal and the target signal are co-located, and N is a positive integer. Taking the SSB as an example, if the advance indication signal is sent within a certain time window relative to the SSB, it is determined that both satisfy the QCL relationship. Taking CSI-RS as an example, if the advance indication signal is transmitted within a certain time window relative to the CSI-RS, it is determined that the QCL relationship is satisfied between the two. Taking the PDCCH as an example, if the advance indication signal is transmitted within a certain time window relative to the PDCCH, it is determined that the QCL relationship is satisfied between the two. If the WUS sent on a different bandwidth part (BWP) is used to indicate whether the PDCCH needs to be monitored on the BWP, the WUS sent on the same BWP and the indicated PDCCH on the same frequency band need to receive the PDCCH, The PDCCH-DMRS, PDSCH, and PDSCH-DMRS satisfy the QCL relationship.

Alternatively, when the frequency interval between the first transmission resource and the second transmission resource is less than a preset threshold, determining the advance indication signal and the target signal quasi co-location. Taking the advance indication signal as WUS and the target signal as SSB as an example, when the frequency between WUS and SSB is less than delta_f, it is determined that the QCL relationship is satisfied between the two. Taking the CSI-RS as an example, when the frequency interval between the advance indication signal and the CSI-RS is less than delta_f, that is, in the same frequency range, it is determined that the QCL relationship is satisfied between the two. Taking the PDCCH as an example, when the frequency interval between the advance indication signal and the control resource set (CORESET) where the PDCCH to be monitored is located is smaller than delta_f, that is, in the same frequency range, it is determined that the QCL relationship is satisfied between the two.

Or determining that the advance indication signal and the target signal are quasi-coordinated when the first transmission resource and the second transmission resource are separated by a preset time interval, and the frequency interval between the first transmission resource and the second transmission resource is less than a preset threshold. site. Taking the target signal as the SSB as an example, when the time interval between the advance indication signal and the SSB is T1, and the frequency between the advance indication signal and the SSB is less than delta_f, it is determined that the QCL relationship is satisfied between the two. Similarly, when the target signal is a CSI-RS or a PDCCH, the manner of determining whether it is quasi-co-located with the advance indication signal is similar to the foregoing SSB, and therefore no further details are provided herein.

In addition, in addition to the implementation manner of the second method described above, in the scenario where the advance indication signal is transmitted in the form of a signal sequence, if the advance indication signal is generated based on a certain target signal resource index, the advance indication signal is considered The QCL is satisfied between the target signals corresponding to the target signal resource index. Taking the target signal as the SSB as an example, if the advance indication signal is generated based on a certain SSB resource index, it is considered that the advance indication signal and the SSB corresponding to the SSB resource index satisfy the QCL. For example, if the advance indication signal is sent in the form of a gold sequence, then if the gold sequence is initialized or scrambled using the SSB resource index, it is determined that both are QCL. Alternatively, the advance indication signal is transmitted in the form of a ZC sequence, and if the ZC sequence uses the SSB resource index to determine the root sequence and/or the cyclic shift value, then both are determined to be QCL. Alternatively, the advance indication signal is transmitted in the form of a CGS sequence which is a sequence determined according to the SSB resource index, and then both are determined to be QCL. Alternatively, the advance indication signal is transmitted in the form of a walsh sequence, and if the walsh sequence is determined according to the SSB resource index, it is determined that both are QCL.

Taking the CSI-RS as an example, if the advance indication signal is generated based on a certain CSI-RS resource index, the QCL is considered to be satisfied between the advance indication signal and the CSI-RS corresponding to the CSI-RS resource index. For example, if the advance indication signal is transmitted in the form of a gold sequence, if the gold sequence is initialized or scrambled using the CSI-RS resource index, it is determined that both are QCL. Alternatively, the advance indication signal is transmitted in the form of a ZC sequence, and if the ZC sequence uses the CSI-RS resource index to determine the root sequence and/or the cyclic shift value, it is determined that both are QCLs. Alternatively, the advance indication signal is transmitted in the form of a CGS sequence which is a sequence determined according to the CSI-RS resource index, and then both are determined to be QCL. Alternatively, the advance indication signal is transmitted in the form of a walsh sequence, and if the walsh sequence is determined according to the CSI-RS resource index, it is determined that both are QCL.

In an optional embodiment, the step of step 32 includes: receiving a target signal from the network device side according to the quasi co-location parameter of the advance indication signal; or receiving the advance from the network device side according to the quasi co-location parameter of the target signal Indication signal. For example, the system information includes a QCL relationship indication between the WUS and the SSB. For the idle state terminal according to the QCL relationship indicated by the system information, when receiving the WUS, the WUS reception is performed using the same quasi co-location parameter as the SSB of its QCL. Alternatively, the QCL relationship between the WUS and a certain SSB or a certain CSI-RS is indicated by RRC dedicated signaling or MAC-CE. For the connected state and the terminal at the C-DRX, the SSB or CSI with its QCL may be used. The same quasi-co-location parameters of the RS are used for WUS reception.

When the target signal is a signal carried in the physical downlink channel, step 32 includes: receiving, according to the quasi co-location parameter of the advance indication signal, a signal carried in the physical downlink channel from the network device side. Taking the PDCCH as an example, if the advance indication signal and the PDCCH are quasi-co-located, the reception beam that is the same as the advance indication signal of its QCL can be used for reception when receiving the PDCCH. In this way, the receiving end can be conveniently determined to determine the preferred receiving beam, avoiding the complexity caused by repeated beam training, and is beneficial to the terminal to save power.

In the information transmission method of the embodiment of the present disclosure, the terminal determines the quasi-co-location relationship between the advance indication signal and the target signal, and directly receives the advance indication signal or the target signal from the network device side according to the quasi co-location parameter when the two are quasi-co-located. Without complicated beam training, better reception performance can be ensured, and the terminal can save power.

The above embodiment describes the information transmission method in different scenarios. The terminal corresponding thereto will be further introduced in the following with reference to the accompanying drawings.

The method is an explicit indication mode, and the target signal is SSB as an example, and the QCL relationship between the advance indication signal and the SSB corresponding to an SSB resource index number is indicated by system information, RRC dedicated signaling, MAC-CE or DCI. . Taking the CSI-RS as an example, the QCL relationship between the advance indication signal and the CSI-RS corresponding to a certain CSI-RS resource index number is indicated by system information, RRC dedicated signaling, MAC-CE or DCI.
