technical field

The present disclosure relates to the field of communication technologies, and in particular, refers to an information indication method, an acquisition method, a device, a network side device, and a terminal.

Background technique

In the fifth-generation mobile communication technology (5th-Generation, 5G) new air interface (New Radio, NR) system, the current working state of the user equipment (User equipment, UE) is divided into three types: radio resource control idle state (Radio Resource control -Idle, RRC_IDLE), radio resource control inactive state (Radio Resource control-Inactive, RRC-Inactive) and radio resource control connected state (Radio Resource control-Connected, RRC-Connected). Only the UE in RRC-Connected is allowed to detect the Physical Downlink Control Channel (PDCCH) scrambled by Cell-Radio Network Temporary Indentifier (C-RNTI).

For NR systems, power saving and reception robustness optimization in RRC_IDLE or RRC-Inactive mode are also very important. For RRC_IDLE or RRC-Inactive terminals, the base station does not know which base station the UE resides in. Notify the UEs in the RAN-based Notification Area (RNA), the base station or the core network will send a paging signal to wake up the UEs to enter the RRC-Connected mode to receive data, or to receive system information Radio Network Tempory Identity, RNTI) (System information-RNTI, SI-RNTI) scrambled system information update. Therefore, for the RRC_IDLE or RRC_Inactive mode, the UE will receive paging and system information (System Information, SI). For paging messages, the base station will configure a UE-specific Discontinuous Reception (DRX) cycle for the terminal; from the perspective of the terminal, the terminal will have an opportunity to monitor paging every other DRX cycle. The paging message is composed of paging downlink control information (Downlink control Information, DCI) and Paging physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

During the active time (Active Time), in addition to receiving the Synchronization Signal Block (SSB), the base station also configures the Channel State Information Reference Signal (CSI-RS) and/or Time-frequency tracking reference signal (Tracking Reference Signal, TRS). In the current technology, the base station configures CSI-RS or TRS for the UE in the connected state. The transmission of the CSI-RS/TRS may be deactivated soon after the UE in the connected state completes the transmission, resulting in the reference signal configured by the base station for the UE in the idle state. (Reference Signal, RS) resources may not have RS transmission. For UEs in the idle state or inactive state, it is impossible to accurately know whether there is a reference signal on the reference signal resource, which increases the blind detection operation of the UE, and further increases the Power consumption of an inactive UE.

As another optional embodiment, the effective time is associated with the position of the reference signal; wherein, different positions of the reference signal correspond to different effective times;

For example, the effective time corresponding to the availability of the reference signal indicated by the PEI is associated with the position of the reference signal, and different positions of the reference signal have different effective time or effective interval.

For example, the reference signal is located between the PEI and the Paging Opportunity (PO), the effective range of the PEI is the current DRX cycle, and the effective range of the reference signal after the PO is at least the next DRX cycle, or the valid timer=0.

If default_TRS_configuration=1 carried by the physical layer signaling, when the L1 signaling indication fails, the terminal determines the TRS availability according to the SI signaling indication;

In order to more clearly describe the information indication method and the information acquisition method provided by the embodiments of the present disclosure, several examples are used below for illustration.

example one

Step 1, the network side device configures the first transmission resource; the base station configures the CSI-RS/TRS transmission resource for the RRC idle/inactive UE through high-level signaling (such as system information SIB-X).

Step 2, indicating the signaling type of the first signaling to the first terminal through physical layer signaling; including scheme 1, scheme 2, scheme 3 and scheme 4.

Among them, scheme 1:

The base station uses physical layer signaling to explicitly instruct the terminal to determine the corresponding reference signal availability (RS availability) on the first transmission resource according to higher layer signaling (preferably, SI signaling) or physical layer signaling. Preferably, the above explicit indication is the physical layer signaling using bitmap or code point to indicate the signaling type for determining the availability of the reference signal. The preferred physical layer signaling (for example, layer 1 signaling) is PDCCH, such as paging DCI or PDCCH based (PDCCH based) PEI, paging DCI has 6 bits reserved bits, at least one bit or one code point It can be used to indicate the signaling type for determining the availability of the reference signal. At least one bit or one code point in the DCI corresponding to the PDCCH based PEI can be used to indicate the signaling type for the terminal to determine the availability of the reference signal.

Before displaying the signaling type indicating the first signaling through the physical layer signaling, the base station uses high-level signaling (preferably, system information) to configure the position of the indication reference signal availability field in the L1 signaling for the terminal, at least including The starting point information and occupied length of this field in DCI, at least one bit or one code point is used to determine the signaling type indicating the availability of reference signals, and other bits or code points are used to determine the availability of specific reference signals sex. For example, the first available bit or code point of the reference signal availability field can be used to determine the signaling type referring to the reference signal availability.

Optionally, the base station uses the L1 signaling to configure the SI signaling and/or L1 signaling valid or valid time indicating the availability of the reference signal for the terminal, where the SI or L1 signaling takes effect only within the validate timer configured by the base station.

When the first available bit/code point of the field indicating the availability of the reference signal is the first preset value (for example, 1), the base station instructs the terminal to determine the corresponding CSI-RS on the first transmission resource according to layer 1 signaling /TRS availability;

When the first available bit/code point of the field indicating the availability of the reference signal is the second preset value (for example, 0), the terminal is instructed to determine the corresponding CSI on the first transmission resource according to high-layer signaling (such as SI) -Availability of RS/TRS.

Optionally, when the Layer 1 signaling instructs the terminal to use SI to determine the availability of the corresponding CSI-RS/TRS on the first transmission resource, except for the above bit indicating the signaling type, other bits in the availability field are all 0 bits.

Optionally, when the Layer 1 signaling instructs the terminal to use SI to determine the availability of the corresponding CSI-RS/TRS on the first transmission resource, in addition to the above-mentioned bits indicating the signaling type, other bits in the availability field are optionally used for Indicates the valid or effective time of the SI signaling. For the terminal, SI only takes effect within the validate timer configured in L1 signaling.

Optionally, the base station and the terminal agree in advance on the default mode of the availability indication, for example, agree in advance to determine the availability of the CSI-RS/TRS according to the L1 signaling indication. The default mode is the TRS availability corresponding to the configured reference signal sending opportunity when no L1 signaling indicates the TRS availability.

The above example mainly describes the PDCCH-based layer 1 signaling. The layer 1 signaling/channel also includes sequence-based signals, such as sequence based PEI. At this time, the sequence based PEI can use different code points The modes corresponding to different sequences or different transmission resources are used to indicate the signaling type of CSI-RS/TRS availability.

The beneficial effect of solution 1 is that: the semi-static configuration of high-level signaling in the related art indicates whether the signaling type of CSI-RS/TRS availability is SI or layer 1 signaling. The disadvantage is that the system information configuration changes very slowly, and frequent reception of system information updates has high power consumption of the terminal. Therefore, only in the scene where the CSI-RS/TRS changes slowly, the SI indicating the availability of the CSI-RS/TRS will be very effective for the UE Energy-saving effect; if the reference signal in the connected state changes rapidly, using L1 signaling to indicate the availability of CSI-RS/TRS may provide a small energy-saving gain for the UE, but it can prevent the UE from frequently reading the information triggered by the TRS update SI update. For most actual scenarios, the base station cannot predict the types of connected services and their transmission characteristics for a long time (only a few extreme scenarios can be sure to use slow-changing CSI-RS/TRS), and only layer 1 can be configured at this time Signaling is indicated by paging DCI. Since paging DCI is only sent when there is a paging message, using paging DCI signaling to indicate the availability of CSI-RS/TRS when TRS actually changes slowly will result in additional Paging DCI signaling On the other hand, when the TRS changes slowly, if there is a lack of paging DCI to indicate the availability of CSI-RS/TRS, the terminal cannot be indicated that there is a TRS on the CSI-RS/TRS resource, so that it cannot use TRS to save energy. Therefore, the use of L1 signaling in the present disclosure to instruct the terminal to switch flexibly to indicate the type of CSI-RS/TRS availability is beneficial to energy saving of the terminal and reduction of overhead at the base station side. At the same time, it can be realized that the switch between system message indication and L1 signaling indication can be realized without using the system message update method, which not only provides higher flexibility for the base station, but also does not need to read system information frequently on the base station side, so as to realize terminal energy saving.

Scenario 2:

The base station uses physical layer signaling to explicitly indicate that the first CSI-RS/TRS resource/resource set uses SI information to indicate its corresponding RS availability, the second CSI-RS/TRS resource/resource set or the third CSI-RS/TRS A resource/resource set uses L1 signaling to indicate its corresponding RS availability. Preferably, for example, the base station configures at least two CSI-RS/TRS resources/resource sets through SIB-X, which are respectively the first CSI-RS/TRS resource/resource set and the second CSI-RS/TRS resource/resource set, The first CSI-RS/TRS resource/resource set and the first CSI-RS/TRS resource/resource set constitute a third CSI-RS/TRS resource/resource set.

The explicit bitmap or code point of the L1 signaling indicates the RS availability corresponding to different CSI-RS/TRS resources/resource sets respectively. details as follows:

The base station configures the position of the field indicating the availability of the CSI-RS/TRS in the L1 signaling for the terminal by using high-level signaling (preferably system information). For example, the base station uses system information to configure the position of the CSI-RS/TRS availability indication bit corresponding to the first CSI-RS/TRS resource/resource set in the CSI-RS/TRS availability indication field of L1 signaling; the base station uses system information to configure The position of the CSI-RS/TRS availability indication bit corresponding to the second CSI-RS/TRS resource/resource set in the CSI-RS/TRS availability indication field of L1 signaling. The location information preferably includes the starting point of the location and the bit length it occupies or the range of the code point.

Optionally, the CSI-RS/TRS availability indication field in L1 signaling (such as paging DCI) includes N bits, where the first indicates N1 bits, for example, N1=1 is used to indicate the first CSI-RS/TRS resource/resource The CSI-RS/TRS availability corresponding to the set, and the second indication N2 bits are used to indicate the CSI-RS/TRS availability corresponding to the second CSI-RS/TRS resource/resource set or the third resource/resource set.

The L1 signaling can at least use the first indication N1=1 bit (SI_ON_OFF) to activate or deactivate the SI indication CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set.

If SI_ON_OFF=1, the terminal uses SI signaling to determine the CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set in the first CSI-RS/TRS resource/resource set; and the terminal is in the second The CSI-RS/TRS resource/resource set uses L1 signaling to determine the CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set.

If the first indication SI_ON_OFF=0, the terminal uses L1 signaling to determine the CSI-RS/TRS availability corresponding to the third CSI-RS/TRS resource/resource set. Optionally, the base station indicates the CSI-RS/TRS availability corresponding to the third CSI-RS/TRS resource/resource set by using the second indication bit and/or the second indication bit.

The beneficial effect of the solution 2 is that: since the CSI-RS/TRS resources/resource sets come from connected UEs, different UEs often correspond to different CSI-RS/TRS resources, which often causes the base station to configure CSI for some connected UEs. -RS/TRS resources may change slowly and belong to semi-static periodic CSI-RS/TRS resources, and another part of CSI-RS/TRS resources may correspond to fast-changing CSI-RS/TRS resources, and it is not ruled out that there are still some resources In a period of time, it corresponds to a constant/slowly changing CSI-RS/TRS resource, and in another period of time, it corresponds to a rapidly changing CSI-RS/TRS. The embodiments of the present disclosure further distinguish CSI-RS resources with different characteristics. Preferably, the first CSI-RS/TRS resource with a high probability of slow change uses SI to indicate the CSI-RS/TRS availability. The faster second CSI-RS/TRS resource uses L1 signaling to indicate CSI-RS/TRS availability. When the SI indication of the first CSI-RS/TRS resource is dynamically deactivated, all the third CSI-RS/TRS TRS resources use L1 signaling to indicate CSI-RS/TRS availability, so that CSI-RS resources with different characteristics can be flexibly indicated to reduce the signaling overhead of the base station and the power consumption of the terminal.

Option 3:

The base station configures SI and L1 signaling to indicate jointly on the same first transmission resource at the same time, and the base station displays through L1 signaling whether to use SIB signaling to indicate TRS after the configured L1 signaling validate timer expires, or when L1 signaling is no longer valid availability.

Better L1 signaling has at least 1 bit bitmap or code point (such as default_TRS_configuration). If default_TRS_configuration=1, it means that after L1 signaling expires, SIB signaling is used to indicate the corresponding CSI-RS/TRS availability on the first transmission resource; if default_TRS_configuration=0, it means that after L1 signaling expires, the corresponding CSI-RS/TRS availability on the first transmission resource There is no CSI-RS/TRS.

More specifically, the base station configures SI and L1 signaling to indicate CSI-RS/TRS availability on the same first transmission resource at the same time. When default_TRS_configuration=1, the default TRS availability indication mode is SI, while L1 signaling is in SI Update the TRS availability indication based on the signaling. At this time, the terminal determines the TRS availability indication according to the L1 signaling. When the L1 signaling indication fails, it determines the TRS availability indication according to the SI signaling indication. When default_TRS_configuration=0, once the L1 signaling fails , the UE assumes that there is no CSI-RS/TRS on the corresponding first transmission resource.

Option 4:

The base station uses the physical layer signaling to implicitly instruct the terminal to determine the availability of the CSI-RS/TRS on the CSI-RS/TRS transmission opportunity according to the SI. Specifically: the base station sends L1 signaling to indicate TRS availability. If neither the paging DCI bit nor the PEI bit is configured with a TRS availability indication field, the terminal is implicitly instructed to use SI signaling to indicate TRS availability; if the L1 signaling is such as paging DCI or PEI Configuring the TRS availability indication field or code point uses L1 signaling to indicate the corresponding CSI-RS/TRS availability on the first transmission resource.

Example two

The base station configures the first CSI-RS/TRS resource/resource set and the second CSI-RS/TRS resource/resource set for the terminal by using SI (such as SIB-X). The base station uses system information to indicate the activation information indicated by L1 signaling on the second CSI-RS/TRS resource/resource set, and the base station uses system information to indicate the deactivation information indicated by L1 signaling on the first CSI-RS/TRS resource/resource set .

Then the terminal determines the corresponding CSI-RS/TRS availability on the first CSI-RS/TRS resource/resource set according to the SI signaling instruction; the terminal determines the corresponding CSI-RS/TRS resource/resource set on the second CSI-RS/TRS resource/resource set according to the L1 signaling instruction. CSI-RS/TRS availability.

The beneficial effect of this example is that: since the CSI-RS/TRS resources/resource sets come from connected UEs, different UEs often correspond to different CSI-RS/TRS resources, which often causes the base station to configure CSI-RS for some connected UEs. The /TRS resources may change slowly and belong to semi-static periodic CSI-RS/TRS resources, and the other part of CSI-RS/TRS resources may correspond to fast-changing CSI-RS/TRS resources. In this disclosure, CSI-RS resources with different characteristics are further distinguished. Preferably, SI is used to indicate the CSI-RS/TRS availability for the first CSI-RS/TRS resource with a large probability of slow change. The fast second CSI-RS/TRS resource uses L1 signaling to indicate CSI-RS/TRS availability, so as to reduce the signaling overhead of the base station and reduce the power consumption of the terminal.

Example three

The base station uses the SI to configure at least one CSI-RS/TRS resource set, and the transmission beam of the CSI-RS/TRS resource in each CSI-RS/TRS resource set is associated with at least one SSB. The SI signaling indicates the corresponding position of the TRS availability indication bit in the L1 signaling for each CSI-RS resource set or all CSI-RS resource sets or part of the CSI-RS resource sets, or the SI signaling indicates that each CSI-RS resource set The code point corresponding to the RS resource set or all CSI-RS resource sets or part of the CSI-RS resource sets.

Each CSI-RS/TRS availability indication bit of L1 signaling, or code point indicates the CSI-RS/TRS availability corresponding to the corresponding transmission resource set, specifically:

Each CSI-RS/TRS availability indication bit of L1 signaling, or the CSI-RS/TRS resource set indicated by each code point only corresponds to the same transmission beam.

or,

Each CSI-RS/TRS availability bit of L1 signaling, or the CSI-RS/TRS resource set indicated by each code point corresponds to all transmission beams, and all transmission beams are all CSI-RS configured by the base station through SI signaling The complete set of transmit beams corresponding to the /TRS resource. Preferably, the base station configures a plurality of bits in the L1 signaling, and each bit is used to indicate a CSI-RS/TRS resource set, and the CSI-RS/TRS resource set is the base station's CSI-RS/TRS occasion (occasion) A subset of all CSI-RS/TRS resources configured through SI signaling, the set of CSI-RS/TRS resources corresponds to the full set of transmit beams.

or,

Each CSI-RS/TRS availability bit of L1 signaling, or the CSI-RS/TRS resource set indicated by each code point corresponds to a group of transmission beams, and the group of transmission beams is a subset of the complete set of transmission beams, The complete set of transmission beams is the complete set of transmission beams corresponding to all CSI-RS/TRS resources configured by the base station through SI signaling. The CSI-RS/TRS resource set indicated by each bit or each code point corresponds to a group of transmission beams: each bit or each code point of L1 signaling corresponds to a group of transmission beams containing at least one adjacent transmission beam right. The meaning of the pair of adjacent transmission beams here is preferably two adjacent transmission beams among the transmission beams corresponding to all CSI-RS/TRS resources configured by the base station through SI signaling, as shown in FIG. The special case of transmit beam pairs corresponding to two adjacent SSBs is excluded. Preferably, as shown in Figure 4, the CSI-RS resource sets indicated by the same bit have adjacent beam pairs within the set, and there are overlapping transmission beams between the CSI-RS/TRS resource sets indicated by different bits. The CSI-RS resources corresponding to the overlapping transmission beams are preferably different CSI-RS resources.

The beneficial effect of this example is: the CSI-RS resources configured by the base station in the connected state for the terminal are generally configured according to the beam. For example, although the CSI-RS is configured exclusively for the terminal, the base station can share the CSI-RS resources of the same transmission beam for different terminals. RS/TRS reduces base station side overhead. When TRS in connected state is used for UE in idle state, L1 signaling is indicated according to the method of beam selection, and TRS resources are beneficial to reduce overhead on the base station side; in addition, each bit of L1 signaling corresponds to multiple transmission beam indications, which is beneficial to use less L1 signaling The bit supports up to 64 transmit beams, which is beneficial to terminal energy saving. The beneficial effect of this solution is mainly that: when the terminal wakes up from the sleep state in the idle state, due to the change of the position, the terminal cannot determine whether it is still under the coverage of the original beam. In the method of the embodiment of the present disclosure, each bit indicates The CSI-RS resource set includes all transmit beams to ensure that the terminal can use TRS to save energy; at the same time, optionally, the base station can configure multiple adjacent transmit beams for the CSI-RS set corresponding to each bit, and the same bit corresponds to The interior of the CSI-RS resource is an adjacent beam, and there are overlapping transmission beams between the CSI-RS resource sets corresponding to different bits, which is beneficial to solve the problem that the terminal cannot determine the transmission beam that can be used due to sleep.

Example four

The base station configures SI and/or L1 signaling to indicate CSI-RS/TRS availability, and the base station configures the validate timer corresponding to the above SI and/or L1 signaling for the terminal by using SI signaling configuration or a pre-agreed or implicit configuration method. When using signaling configuration, it is preferable to configure validate_timer_SIB and/or validate_timer_L1 in the SIB-X where CSI-RS/TRS resources are configured; When the implicit configuration is adopted, an implicit indication may be performed based on the L1 signaling transmission resource and its TRS transmission resource.

The base station configures SI and/or L1 signaling for the terminal to indicate CSI-RS/TRS availability, and the validate timer corresponding to SI and/or L1 signaling: the validate timer corresponding to the TRS availability indicated by the physical layer signaling/SI signaling is the TRS position function, or associated with the location of L1 signaling.

For example, the base station uses high-level signaling to configure the first validate timer value T1 for the PEI, and the base station configures the second validate timer value T2 for the paging DCI. The position of the PEI is always before the Paging DCI, and the preferred first validate timer value T1<=th The second validate timer value T2 or the first validate timer value T1<=the second validate timer value T2 and the first validate timer value T1 is greater than or equal to one DRX cycle.

The beneficial effect is that: although the first validate timer value of at least one DRX cycle is defined for the PEI, although there is no gain for paging reception, it can be beneficial to other data transmissions in the idle state to save energy, such as multimedia broadcasting services transmitted in the idle state, or transmission in the idle state Small data. The value of the first validate timer T1<=the value of the second validate timer T2 is conducive to reducing the overhead of the base station side.

The PEI indicates that the validate timer corresponding to the CSI-RS/TRS availability is associated with the CSI-RS/TRS position, and different positions of the CSI-RS/TRS have different validate timer values, or valid intervals.

The CSI-RS/TRS is located between the PEI and the PO, and the valid range of the PEI is the current DRX cycle; the CSI-RS/TRS is located after the PO and its valid range is at least the next DRX cycle (for example, it can include the current DRX cycle and the next or next DRX cycle). N DRX cycles), or validate timer=0 corresponding to CSI-RS/TRS.

For the CSI-RS/TRS availability indicated by L1 signaling, the base station notifies a threshold value through SI or presets a threshold value through the standard. When the distance between the CSI-RS/TRS configured by the base station exceeds the threshold value, the L1 signaling The CSI-RS/TRS availability indicated by the /SI signaling has a validate timer=0, or at this time, the terminal does not want to use the CSI-RS/TRS resource for the channel tracking operation corresponding to the target resource. If the distance from the CSI-RS/TRS to the target position is less than or equal to the threshold value, the UE assumes that the validate timer corresponding to the CSI-RS resource is greater than 0. The target location may be the sending resource of the PEI signaling, or the sending resource corresponding to the sending service in the idle state, such as paging DCI/paging PDSCH or multimedia broadcast multicast service.

The number of validate timers corresponding to the CSI-RS/TRS availability indicated by the L1 signaling is a function of the signaling sending type, or is associated with the signaling signaling type.

When PEI signaling/SI indicates CSI-RS/TRS availability, the corresponding validate timer has a unique validate timer value; when paging DCI indicates CSI-RS/TRS availability, the corresponding validate timer has at least one timer value.

For example, the base station configures at least one validate timer value for the terminal through the SIB-X, and the base station indicates the actually adopted validate timer value through the paging DCI.

Beneficial effects of Example 4: The current related technologies do not consider the TRS position, because the position of the TRS transmission in the connected state depends on the UE in the connected state, and may not be aligned with the PO position or have a definite relationship. This disclosure provides a A signaling validate timer solution when the base station shares the TRS of the terminal in the connected state with the idle/inactive terminal. By determining the appropriate timer value, it can alleviate the power consumption waste caused by the ambiguity between the base station and the terminal when L1 signaling is missed; Properly configured validate timer values are beneficial to the reduction of signaling overhead on the base station side and the possible saving of terminal reception power consumption.

To sum up, the network side equipment configures the transmission resource corresponding to the reference signal for the terminal in the idle state and/or the terminal in the inactive state, and indicates the availability of the reference signal through the physical layer signaling and/or high-layer signaling, so that the idle state or the inactive state The terminal in the active state can accurately obtain whether there is a reference signal on the first transmission resource, which is beneficial to reduce the overhead of the base station and save the power consumption of the base station and the terminal in different scenarios; it can effectively prevent the terminal in the idle state and/or the terminal in the inactive state from performing reference signals The blind detection operation reduces the power consumption of the terminal.
