Description

Information indication method, information acquisition device, network side equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information indicating method, an information obtaining device, a network side device, and a terminal.

Background

In a 5G NR (New Radio, new air interface) system, currently, the operating states of a UE (User equipment) are divided into three types: radio Resource control Idle (RRC _ Idle), radio Resource control Inactive (RRC-Inactive), and Radio Resource control Connected (RRC-Connected). Only the UE in RRC-Connected is allowed to detect a PDCCH (Physical Downlink Control Channel) scrambled as a C-RNTI (Cell-Radio Network Temporary identifier).

For NR systems, it is also important to optimize power saving and reception robustness in RRC IDLE or RRC Inactive mode. For RRC _ IDLE or RRC-Inactive terminals, the base station does not know which base station the UE resides in, and if for UEs in TA (Tracking Area) or RNA (RAN-based Notification Area), the base station or core network sends a Paging signal to wake up the UEs to enter RRC-Connected mode to receive data or to receive System Information update scrambled by SI-RNTI (System Information-RNTI), so for RRC _ IDLE or RRC _ Inactive mode, the UE receives Paging and System Information (SI).

In Active Time (Active Time), in addition to receiving an SSB (Synchronization Signal Block), the base station configures a Channel State Information Reference Signal (CSI-RS) and/or a Time-frequency Tracking Reference Signal (TRS) for the UE. In the prior art, a base station configures a CSI-RS or a TRS for a connected UE, which may be accompanied by the completion of transmission of the connected UE, to quickly deactivate transmission of the CSI-RS/TRS, so that a Reference Signal (RS) resource configured by the base station for an idle UE may not have transmission of the RS.

It should be noted that the reference signal availability mentioned in the embodiments of the present invention is used to indicate whether a reference signal exists. For example, the availability of reference signals corresponding to a set of transmission resources is used to indicate whether reference signals are present on the set of transmission resources.

In at least one optional embodiment of the present invention, in step 202, the indicating, by the network side device, the signaling type of the first signaling to the first terminal through physical layer signaling includes:

if the first bit or code point of the availability field of the physical layer signaling is a second preset value, the signaling type of the first signaling is high layer signaling, and the terminal determines the availability of the reference signal on the first transmission resource according to the high layer signaling (such as SI).

alternatively, the first and second electrodes may be,

Optionally, the physical layer signaling is Paging Early Indication PEI (Paging Early Indication) signaling and/or Paging Downlink control Information DCI (Downlink control Information).

For example, the network side device sends PEI or paging DCI to the first terminal, and if neither PEI or paging DCI configures a reference signal availability indication field, the PEI or paging DCI implicitly indicates that the signaling type of the first signaling is a high-level signaling, which may also be referred to as that the PEI or paging DCI implicitly indicates that the terminal determines availability of the reference signal according to the high-level signaling; if the PEI or paging DCI thereof configures the reference signal availability indication field, the signaling type of the first signaling is implicitly indicated as physical layer signaling, which may also be referred to as PEI or paging DCI, and implicitly indicates that the terminal determines the reference signal availability according to physical layer signaling (PEI or paging DCI).

For example, the physical layer message includes two second indication fields; a second indication domain is a first value and indicates that the signaling type of a first signaling corresponding to the first transmission resource set is a high-level signaling; and the other second indication field is a second value and indicates that the signaling type of the first signaling corresponding to the second transmission resource set is physical layer signaling.

Optionally, the physical layer signaling may activate or deactivate the higher layer signaling based reference signal availability indication corresponding to the first transmission resource set using at least the first indication field:

if the first indication domain is a first preset value, the terminal determines availability of a reference signal corresponding to the first transmission resource set by adopting high-level signaling (such as SI) in the first transmission resource set; and the terminal determines the availability of the reference signal corresponding to the second transmission resource set by adopting physical layer signaling in the second transmission resource set.

And if the first indication field is a second preset value, the terminal adopts physical layer signaling to determine the availability of the reference signal corresponding to the third resource set. Wherein the third set of resources includes the first set of resources and the second set of resources.

As an alternative embodiment, the method further comprises:

For example, the network side device configures, through the SI, the location information of the first indication field and/or the at least one second indication field in the physical signaling for the first terminal, where the location information includes a bit location or a corresponding code point. The first terminal may determine the location of the first indication field and/or the second indication field according to the corresponding higher layer signaling, thereby accurately determining the signaling type of the first signaling.

In at least one embodiment of the invention, the method further comprises:

Preferably, the first value is equal to 1.

In the embodiment of the present invention, when FR2 is present, the terminal supports multiple receiving beams, and when the terminal wakes up through sleep, the original optimal beam pairing cannot be lost, so that when the first value is 1, the network side device sends the TRS of multiple beams to the terminal, which is beneficial to the terminal to implement channel tracking (channel tracking).

As another optional embodiment, the determining, by the network side device, the number of bits used for the indication of availability of the reference signal in the physical layer signaling and/or the higher layer signaling according to the frequency range in which the first terminal is located includes:

determining that a number of bits used for reference signal availability indication in the physical layer signaling and/or higher layer signaling is greater than or equal to 1 in case the frequency range is a first frequency range (e.g., FR 1).

Optionally, each transmission resource set indicated by a bit of the physical layer signaling used for the reference signal availability indication or each transmission resource set indicated by code point corresponds to only the same transmission beam;

alternatively, each transmission resource set indicated by a bit for reference signal availability indication of physical layer signaling or each transmission resource set indicated by code point respectively corresponds to a group of transmission beams.

In the embodiment of the invention, when FR1, because the terminal supports omnidirectional reception, even if the base station is configured with a TRS of a beam, the terminal can realize normal reception with high probability, thereby receiving the TRS according to the beam indication, and being beneficial to reducing the sending expense of the TRS at the base station side.

and/or the presence of a gas in the atmosphere,

and the network side equipment indicates the activation information indicated by the physical layer signaling corresponding to the second transmission resource set to the first terminal through the high-level signaling, and then the terminal determines the availability of the reference signal corresponding to the second transmission resource set according to the physical layer signaling.

For example, the higher layer signaling is SI, such as the system information block SIB-X.

The network side equipment configures a first transmission resource set and a second transmission resource set for the first terminal by using the first SI, the network side equipment further indicates activation information indicated by physical layer signaling on the second transmission resource set by using the second SI (the second SI and the first SI can be the same SI or different SIs), and further indicates deactivation information indicated by the physical layer signaling of the first transmission resource by using the third SI (the third SI and the second SI can be the same SI or different SIs).

The terminal determines the availability of the reference signal corresponding to the first transmission resource set according to the indication of the high-level signaling; the terminal determines availability of a reference signal corresponding to the second set of transmission resources as indicated by the physical layer signaling.

In at least one optional embodiment of the present invention, in step 202, the indicating, by the network side device, availability of reference signals corresponding to at least one transmission resource set to the first terminal through physical layer signaling and/or higher layer signaling includes:

For example, the network side device configures at least one transmission resource set for the first terminal, and the network side device indicates availability of reference signals corresponding to the respective transmission resource sets by using physical layer signaling and/or higher layer signaling. Wherein 2 availability indication bits or 1 code point correspond to one transmission resource set.

As an optional embodiment, before the network side device indicates availability of the reference signals corresponding to the respective transmission resource sets respectively through N1 availability indication bits or N2 code points included in physical layer signaling, the method further includes:

the network side equipment indicates the corresponding relation between each transmission resource set and the availability indication bit in the physical layer signaling through high layer signaling;

alternatively, the first and second liquid crystal display panels may be,

For example, the network side device indicates the correspondence between each transmission resource set and the availability indication bit or code point in the physical layer signaling by using a higher layer signaling (e.g. SI), and the terminal can determine the availability of the reference signal of each transmission resource set according to the availability indication bit or code point.

In at least one embodiment of the invention, each set of transmission resources corresponds to a full set of transmission beams; for example, the network side device configures multiple bits in physical layer signaling, where each bit is used to indicate reference signal availability of one transmission resource set, where the transmission resource set is a subset of the first transmission resources, and the transmission resource set corresponds to a full set of transmission beams;

or, each set of transmission resources corresponds to a subset of the full set of transmission beams, a subset comprising at least one adjacent pair of beams; overlapping transmit beams exist between different sets of transmission resources;

Optionally, the validity time of the first signaling may be characterized by a value of a validity timer (valid timer), that is, the first signaling is valid during the validity timer running time, and the availability of the reference signal indicated by the first signaling is valid.

As an optional embodiment, the indicating, by the network side device, the validation time of the first signaling to the first terminal through physical layer signaling and/or higher layer signaling includes:

alternatively, the first and second electrodes may be,

the network side equipment indicates the effective time set of the first signaling to the first terminal equipment through a high-level signaling, and indicates the effective time in the effective time set through a physical layer; for example, the base station configures at least one valid timer value for the terminal through SIB-X, and the base station indicates the actually used valid timer value through paging DCI.

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

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 times or effective intervals.

For example, the reference signal is located between PEI and the paging opportunity PO, the effective range of PEI is the current DRX cycle, the effective range of reference signal is at least the next DRX cycle after PO, or the validity timer =0.

Alternatively, the validation time is associated with a location of physical layer signaling and/or higher layer signaling indicating reference signal availability;

optionally, the validation time is 0 when a distance between the first transmission resource configured by the network side device and a location of the physical layer signaling and/or the higher layer signaling indicating the availability of the reference signal exceeds a first threshold value.

For example, the network side device notifies the first threshold value through the SI or predetermines the first threshold value through a standard, and when the distance from the first transmission resource configured by the network side device to the target location (i.e., the location of the physical layer signaling and/or the higher layer signaling indicating the availability of the reference signal) exceeds the first threshold value, the value of the validity timer of the availability of the reference signal indicated by the physical layer signaling and/or the higher layer signaling is 0, that is, the terminal does not want the first transmission resource to be used for the channel tracking operation corresponding to the target location.

As yet another alternative, the number of validation times corresponding to the time of availability of the reference signal indicated by the physical layer signaling or the higher layer signaling is a function of, or associated with, the signaling type of the first signaling;

under the condition that the PEI signaling indicates the availability of the reference signal, the PEI signaling corresponds to a unique effective time; when PEI signaling indicates the availability of a reference signal, the valid timer corresponding to the PEI signaling has a unique valid timer value;

and/or, in case that the SI indicates the availability of the reference signal, the SI corresponds to a unique effective time; also referred to as SI indicates reference signal availability, the SI corresponding to the valid timer has a unique valid timer value;

and/or, the paging DCI corresponds to at least one effective time under the condition that the paging DCI indicates the availability of the reference signal; which may also be referred to as paging DCI, indicates the availability of a reference signal, a valid timer corresponding to the paging DCI has at least one timer value.

In at least one embodiment of the invention, the method further comprises:

For example, after the base station displays the valid timer indicating the physical layer signaling indication by using the physical layer signaling, whether to indicate the availability of the reference signal by using SIB signaling is:

if default _ TRS _ configuration =1 carried by the physical layer signaling, when the L1 signaling indication fails, the terminal determines TRS availability according to the SI signaling indication;

if default _ TRS _ configuration =0, when the L1 signaling indicates failure, the terminal assumes that no reference signal exists on the corresponding first transmission resource.

In at least one embodiment of the invention, the physical layer signaling comprises: paging Early Indication (PEI) signaling, and/or Paging Downlink Control Information (DCI); the high layer signaling comprises: system Information SI (System Information).

Under the condition that the first transmission resource comprises at least two transmission resource sets, the network side equipment can respectively configure the corresponding transmission resource sets for the first terminal through high-level signaling.

In at least one embodiment of the invention, the method further comprises:

In the embodiment of the invention, the network side equipment configures the transmission resources corresponding to the reference signals for the idle state terminal and/or the non-activated state terminal, and indicates the availability of the reference signals through the physical layer signaling and/or the high layer signaling, so that the idle state terminal or the non-activated state terminal can accurately acquire whether the reference signals exist on the first transmission resources, the idle state terminal and/or the non-activated state terminal can be effectively prevented from performing blind detection operation on the reference signals, and the power consumption of the terminal is further reduced.

In order to more clearly describe the information indicating method and the information acquiring method provided by the embodiment of the present invention, the following description is made with reference to several examples.

Example 1

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

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

Wherein, scheme 1:

the base station explicitly instructs the terminal with physical layer signaling and determines the corresponding reference signal availability (RS availability) on the first transmission resource depending on whether higher layer signaling (preferably SI signaling) or physical layer signaling. Preferably, the explicit indication indicates the signaling type for determining the availability of the reference signal in a bitmap or code point manner for physical layer signaling. The preferred physical layer signaling (e.g., layer 1 signaling) is PDCCH, e.g., paging DCI or PDCCH based PEI, where there are 6 reserved bits in the paging DCI, at least one bit or one code point may be used to indicate a signaling type for determining the availability of the reference signal, and at least one bit or one code point in the DCI corresponding to the PDCCH based PEI may be used to indicate a signaling type for determining the availability of the reference signal by the terminal.

Before the signaling type indicating the first signaling is displayed through physical layer signaling, the base station configures the terminal with a position of a field indicating reference signal availability in L1 signaling by using higher layer signaling (preferably, system information), including at least start point information and occupied length of the field in DCI, wherein at least one bit or one code point is used for determining the signaling type indicating the reference signal availability, and other bits or code points are used for determining specific reference signal availability. For example, the first available bit or code point of the reference signal availability field may be used to determine the type of signaling that refers to reference signal availability.

The optional base station configures the terminal with SI signaling indicating reference signal availability and/or L1 signaling validation or validation time by using L1 signaling, wherein the SI or L1 signaling is validated only in the validation timer configured by the base station.

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

and when the first available bit/code point of the field indicating the availability of the reference signal is a second preset value (for example, 0), indicating the terminal to determine the availability of the corresponding CSI-RS/TRS on the first transmission resource according to higher layer signaling (for example, SI).

Optionally, when the layer 1 signaling indication terminal determines the availability of the corresponding CSI-RS/TRS on the first transmission resource by using the SI, except for the bit indicating the signaling type, other bits in a field of the availability are all 0 bits.

Optionally, when the layer 1 signaling indication terminal determines the availability of the corresponding CSI-RS/TRS on the first transmission resource by using the SI, in addition to the bit indicating the signaling type, other bits in the field of the optional availability are used to indicate the validity or effective time of the SI signaling. For the terminal, the SI is only valid within the valid timer of the L1 signaling configuration.

The optional base station and the terminal pre-agree on a default mode indicated by the availabilities, for example, pre-agree on availabilities for determining 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 there is no L1 signaling indicating TRS availability.

The above example mainly describes layer 1 signaling based on PDCCH, and the layer 1 signaling/channel further includes a sequence based signal, such as sequence based PEI, in which case the sequence based PEI can be used to indicate the availabilities signaling type of CSI-RS/TRS in a manner that different code points correspond to different sequences or different transmission resources.

The beneficial effects of the scheme 1 are as follows: the prior art high layer signaling semi-static configuration indicates whether the signaling type of availability of the CSI-RS/TRS is SI or layer 1 signaling. The method has the defects that the configuration change of the system information is slow, and the frequent reception of the system information update has high terminal power consumption, so that the SI indicates the availability of the CSI-RS/TRS to have very effective UE energy-saving effect only under the scene that the CSI-RS/TRS changes slowly; if the connection state reference signal is rapidly changed, the indication of availability of the CSI-RS/TRS using L1 signaling may provide the UE with a small power saving gain, but may allow the UE to avoid frequently reading the SI update triggered by TRS update. For most practical scenarios, the base station cannot predict the type and transmission characteristics of the connection-state service for a long time (only few extreme scenarios can determine that the slowly-changing CSI-RS/TRS is definitely used), at this time, only layer 1 signaling such as Paging DCI indication can be configured, because the Paging DCI is sent only when a Paging message exists, indicating the availability of the CSI-RS/TRS by using the Paging DCI signaling leads to extra Paging DCI signaling overhead when the TRS actually changes slowly, on the other hand, if the Paging DCI indicates the availability of the CSI-RS/TRS, the terminal cannot be indicated as the existence of the TRS on the CSI-RS/TRS resource, and thus cannot use the TRS to save energy. Therefore, the method and the device for indicating the terminal to flexibly switch and indicate the availabilities of the CSI-RS/TRS by utilizing the L1 signaling are beneficial to the reduction of terminal energy saving and base station side overhead. Meanwhile, the switching between the system message indication and the L1 signaling indication can be realized without adopting a system message updating mode, so that higher flexibility is provided for the base station, and meanwhile, the base station side does not need to read the system message frequently, and the energy conservation of the terminal is realized.

Scheme 2:

the base station utilizes physical layer signaling to indicate explicitly, the first CSI-RS/TRS resource/resource set indicates the corresponding RS availability by adopting SI information, and the second CSI-RS/TRS resource/resource set or the third CSI-RS/TRS resource/resource set indicates the corresponding RS availability by adopting L1 signaling. Preferably, for example, the base station configures at least two sets of CSI-RS/TRS resources/resources through SIB-X, a first set of CSI-RS/TRS resources/resources and a second set of CSI-RS/TRS resources/resources, respectively, and the first set of CSI-RS/TRS resources/resources constitute a third set of CSI-RS/TRS resources/resources.

Explicit bitmap or code point of the L1 signaling indicates RS availability corresponding to different CSI-RS/TRS resources/resource sets, respectively. The method comprises the following specific steps:

the base station configures the terminal with the location of the field indicating the availability of the CSI-RS/TRS in the L1 signaling using higher layer signaling (preferably, system information). For example, the base station configures 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 the L1 signaling by using the system information; and the base station configures 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 the L1 signaling by using the system information. The position information preferably includes a position start point and a bit length occupied by the position start point or a range of code points.

Optionally, the CSI-RS/TRS availability indication field in the L1 signaling (e.g., the paging DCI) includes N bits, where a first indication N1 bits, e.g., N1=1, is used to indicate the CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set, and a second indication N2 bits is used to indicate the CSI-RS/TRS availability corresponding to the second CSI-RS/TRS resource/resource set or the third CSI-RS/TRS availability corresponding to the third CSI-RS/TRS resource set.

The L1 signaling may activate or deactivate the SI indication CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set with at least a first indication N1=1 bit (SI _ ON _ OFF).

If SI _ ON _ OFF =1, the terminal determines the CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set by adopting SI signaling in the first CSI-RS/TRS resource/resource set; and the terminal determines the CSI-RS/TRS availability corresponding to the first CSI-RS/TRS resource/resource set by adopting L1 signaling in the second CSI-RS/TRS resource/resource set.

And if the first indication SI _ ON _ OFF =0, the terminal determines the CSI-RS/TRS availability corresponding to the third CSI-RS/TRS resource/resource set by adopting L1 signaling. And the optional 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 effects of the scheme 2 are as follows: because the CSI-RS/TRS resource/resource sets are from connected UEs, different UEs often correspond to different CSI-RS/TRS resources, which often results in that CSI-RS/TRS resources configured by a base station for part of connected UEs may slowly change and belong to semi-static periodic CSI-RS/TRS resources, and another part of CSI-RS/TRS resources may correspond to rapidly changing CSI-RS/TRS resources, while it is not excluded that there are some CSI-RS/TRS resources corresponding to unchanged/slowly changing CSI-RS/TRS resources within a period of time and another CSI-RS/TRS resources corresponding to rapidly changing CSI-RS/TRS within a period of time. The CSI-RS resources with different characteristics are further distinguished, SI is preferably adopted to indicate the CSI-RS/TRS availability for the first CSI-RS/TRS resource with higher probability and slowly changing, L1 signaling is adopted to indicate the CSI-RS/TRS availability for the second CSI-RS/TRS resource with higher probability and changing speed, and after the SI indication of the first CSI-RS/TRS resource is dynamically deactivated, all the third CSI-RS/TRS resources adopt L1 signaling to indicate the CSI-RS/TRS availability, so that the CSI-RS resources with different characteristics are flexibly indicated, the signaling overhead of a base station is reduced, and the power consumption of a terminal is reduced.

Scheme 3:

the base station configures the common indication of the SI and the L1 signaling on the same first transmission resource at the same time, and after the base station displays the configured L1 signaling valid timer through the L1 signaling, or when the L1 signaling is not valid any more, whether the SIB signaling is adopted to indicate the TRS availability or not.

Preferred L1 signaling has at least 1 bit bitmap or code point (e.g., default _ TRS _ configuration). If default _ TRS _ configuration =1, indicating that, after the L1 signaling is over, the SIB signaling is used to indicate the corresponding CSI-RS/TRS availability on the first transmission resource; if default _ TRS _ configuration =0, it indicates that there is no CSI-RS/TRS on the first transmission resource after the L1 signaling is over.

More specifically, the base station configures, on the same first transmission resource, the SI and the L1 signaling to jointly indicate CSI-RS/TRS availability, when default _ TRS _ configuration =1, the default TRS availability indication mode is SI, and the L1 signaling updates the TRS availability indication on the basis of the SI signaling, at this time, the terminal determines the TRS availability indication according to the L1 signaling, and when the L1 signaling indicates failure, the TRS availability indication is determined according to the SI signaling indication; when default _ TRS _ configuration =0, upon L1 signaling failure, the UE assumes that CSI-RS/TRS does not exist on the corresponding first transmission resource.

Scheme 4:

and the base station implicitly indicates the terminal to determine the availability of the CSI-RS/TRS on the CSI-RS/TRS transmission opportunity according to the SI by utilizing the physical layer signaling. The method specifically comprises the following steps: the base station sends an L1 signaling indication TRS availability, if neither the paging DCI bit nor the PEI bit is configured with a TRS availability indication field, the implicit indication terminal adopts SI signaling indication TRS availability; and if the L1 signaling is configured with the TRS availability indication field or code point such as the paging DCI or the PEI, adopting the L1 signaling to indicate the corresponding CSI-RS/TRS availability on the first transmission resource.

Example two

The base station configures a first set of CSI-RS/TRS resources/resources and a second set of CSI-RS/TRS resources/resources for the terminal using the SI (e.g., SIB-X). The base station indicates the activation information indicated by the L1 signaling on the second CSI-RS/TRS resource/resource set by using the system message, and the base station indicates the deactivation information indicated by the L1 signaling on the first CSI-RS/TRS resource/resource set by using the system message.

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

This example has the beneficial effects that: because the CSI-RS/TRS resource/resource sets are from connected UEs, different UEs often correspond to different CSI-RS/TRS resources, which often results in that the CSI-RS/TRS resources configured by the base station for part of connected UEs may change slowly and belong to semi-static periodic CSI-RS/TRS resources, and another part of CSI-RS/TRS resources may correspond to rapidly changing CSI-RS/TRS resources. According to the invention, CSI-RS resources with different characteristics are further distinguished, SI is preferably adopted for indicating CSI-RS/TRS availability for a first CSI-RS/TRS resource with higher probability and slowly changing, and L1 signaling is adopted for indicating CSI-RS/TRS availability for a second CSI-RS/TRS resource with higher probability and fast changing, so that the aims of reducing signaling overhead of a base station and reducing power consumption of a terminal are achieved.

Example three

The base station configures at least one CSI-RS/TRS resource set by using the SI, and the transmission beam of the CSI-RS/TRS resource in each CSI-RS/TRS resource set is associated with at least 1 SSB. The SI signaling indicates the corresponding position of the TRS availability indication bit corresponding to each CSI-RS resource set or all CSI-RS resource sets or part of CSI-RS resource sets in the L1 signaling, or the SI signaling indicates the code point corresponding to each CSI-RS resource set or all CSI-RS resource sets or part of CSI-RS resource sets.

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

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

Alternatively, the first and second electrodes may be,

each CSI-RS/TRS availability bit of the L1 signaling or each CSI-RS/TRS resource set indicated by the code point corresponds to all sending beams, and all the sending beams are the full set of the sending beams corresponding to all the CSI-RS/TRS resources configured by the base station through the SI signaling. Preferably, the base station configures a plurality of bits in the L1 signaling, where each bit is used to indicate one CSI-RS/TRS resource set, where the CSI-RS/TRS resource set is a subset of all CSI-RS/TRS resources configured by the base station for CSI-RS/TRS scheduling through SI signaling, and the CSI-RS/TRS resource set corresponds to a full set of transmission beams.

Alternatively, the first and second electrodes may be,

each CSI-RS/TRS availability bit of L1 signaling or each CSI-RS/TRS resource set indicated by code point corresponds to a group of transmission beams, the group of transmission beams is a subset of a total transmission beam set, and the total transmission beam set is the total transmission beam set corresponding to all CSI-RS/TRS resources configured by a base station through SI signaling. The CSI-RS/TRS resource set indicated by each bit or each code point corresponds to a group of sending beams: the group of transmission beams corresponding to each bit or each code point of the L1 signaling contains at least one adjacent transmission beam pair. The meaning of the adjacent transmission beam pairs here is preferably that the base station configures two adjacent transmission beams among the transmission beams corresponding to all CSI-RS/TRS resources through SI signaling, as shown in fig. 4, although this special case of transmission beam pairs corresponding to two adjacent SSBs is not excluded. Preferably, as shown in fig. 4, adjacent beam pairs exist in the set of CSI-RS resources indicated by the same bit, and overlapping transmission beams also exist between CSI-RS/TRS resource sets indicated by different bits, although CSI-RS resources corresponding to the overlapping transmission beams are preferably different CSI-RS resources.

The beneficial effects of this example are: the CSI-RS resources configured for the terminal by the connected base station are generally configured according to beams, for example, although the CSI-RS is configured for the terminal, the base station may reduce the overhead on the base station side for CSI-RS/TRS that different terminals share the same transmission beam. When the connection state TRS is used for the idle state UE, the L1 signaling indicates according to a beam selection method, and TRS resources are beneficial to reducing the overhead of a base station side; in addition, the indication that each bit of the L1 signaling corresponds to a plurality of transmission beams is favorable for supporting 64 transmission beams at most by using less L1 signaling bits, thereby being favorable for saving energy of the terminal. The beneficial effect of this scheme more mainly lies in: when the terminal wakes up from a sleep state in an idle state, the terminal cannot determine whether the terminal is still under the coverage of the original beam or not due to the change of the position; meanwhile, the optional base station side can configure a plurality of adjacent transmitting beams for the CSI-RS set corresponding to each bit, adjacent beams are arranged in the CSI-RS resource corresponding to the same bit, and overlapped transmitting beams exist among the CSI-RS resource sets corresponding to different bits, so that the problem that the terminal cannot determine the transmitting beams which can be adopted due to sleep is solved.

Example four

The base station configures SI and/or L1 signaling indication CSI-RS/TRS availability, and the base station configures a valid timer corresponding to the SI and/or L1 signaling for the terminal by using an SI signaling configuration or a method of pre-engagement or implicit configuration. When the signaling configuration is adopted, valid _ timer _ SIB and/or valid _ timer _ L1 can be preferably configured in SIB-X configuring CSI-RS/TRS resources; when the pre-agreed method is adopted, the pre-agreed method is preferably pre-agreed by a standard, and when the implicit configuration is adopted, the implicit indication can be performed based on the L1 signaling transmission resource and the TRS transmission resource thereof.

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

For example, the base station configures a first valid timer value T1 for the PEI by using high-layer signaling, the base station configures a second valid timer value T2 for the Paging DCI, and the PEI position always precedes the Paging DCI, where the first valid timer value T1< = the second valid timer value T2 or the first valid timer value T1< = the second valid timer value T2 is preferred, and the first valid timer value T1 is greater than or equal to one DRX cycle.

Has the advantages that: defining a first valid timer value for at least one DRX cycle for PEI, although not a gain for paging reception, may facilitate idle state other data transmission power savings, such as idle state transmitted multimedia broadcast services, or idle state transmitted small data (small data). The first valid timer value T1< = the second valid timer value T2 facilitates base station side overhead reduction.

The PEI indicates that a valid 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 valid timer values or effective intervals.

The CSI-RS/TRS is positioned between the PEI and the PO, and the effective range of the PEI is the current DRX period; the valid range of the CSI-RS/TRS after the PO is at least the next DRX cycle (e.g., may include the current DRX cycle and the next or next N DRX cycles), or the valid timer =0 corresponding to the CSI-RS/TRS.

The method comprises the steps that a base station informs a threshold value through SI or presets a threshold value through a standard, when the distance between the CSI-RS/TRS configured by the base station and a target position exceeds the threshold value, the CSI-RS/TRS availability indicated by the L1 signaling/SI has a valid time =0, or the terminal does not want to use the CSI-RS/TRS resource for channel tracking operation corresponding to the target resource. And the distance between the CSI-RS/TRS and the target position is smaller than or equal to the threshold value, and the UE assumes that the valid timer corresponding to the CSI-RS resource is larger than 0. The target position may be a transmission resource of the PEI signaling, or may be a transmission resource corresponding to an idle state transmission service such as a paging DCI/paging PDSCH or a multimedia broadcast multicast service.

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

The valid timer corresponding to the CSI-RS/TRS availability indicated by the PEI signaling/SI has a unique valid timer value; the corresponding valid timer has at least one timer value when the CSI-RS/TRS availability indicated by the paging DCI.

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

The beneficial effects of this example four: the present prior art does not consider the TRS position, because the position sent by the TRS in the connection state depends on the UE in the connection state, and may not align to the PO position or have a certain relationship, the present invention provides a signaling valid timer solution when the TRS in the connection state is shared by the base station to the idle/inactive terminal, and by determining a proper timer value, it is able to alleviate the power consumption waste caused by the ambiguity of the base station and the terminal understanding when the L1 signaling is missed; the properly configured valid timer value is beneficial to reducing the signaling overhead of the base station side and saving the possible receiving power consumption of the terminal.

In summary, the network side device configures transmission resources corresponding to the reference signal for the idle terminal and/or the inactive terminal, and indicates availability of the reference signal through physical layer signaling and/or high layer signaling, so that the idle terminal or the inactive terminal can accurately obtain whether the reference signal exists on the first transmission resource, which is beneficial to reducing overhead of the base station and saving power consumption of the base station and the terminal in different scenarios; the method can effectively avoid the reference signal blind detection operation of the idle state terminal and/or the inactive state terminal, and further reduce the power consumption of the terminal.
