Description

Information transmission method and device, communication equipment and storage medium

Technical Field

The disclosed embodiments relate to the field of wireless communications, but not limited to the field of wireless communications, and in particular, to an information transmission method and apparatus, a communication device, and a storage medium.

Background

A User Equipment (UE) terminal has a Discontinuous Reception (DRX) state, and the terminal in the DRX state consumes less power than a terminal in a connected state.

For example, with a Narrowband (NB) device, it may be periodically hibernated and awakened, and power consumption of the narrowband device is reduced by the hibernation.

In order to further save power consumption of the UE in the DRX state, a Wake UP Signaling (WUS) is also introduced, the WUS transmits before the Wake UP period, and the terminal determines whether the Wake UP state needs to be maintained in the subsequent Wake UP period by monitoring the WUS to monitor the PDCCH. The WUS signal here can again be a power save signal.

When a base station needs to page a UE in a sleep state, it needs to acquire the configuration of the UE on a power saving signal, and then sends a Paging message at a Paging Occasion (PO) when the UE is in an awake state, so as to improve the Paging success rate of the UE. However, when the precondition of paging the UE is successful, the power saving signal configuration of the UE is successfully obtained, but the acquisition of the power saving signal configuration in the related art has a problem of long transmission path or long acquisition delay.

As shown in fig. 2, the present embodiment provides an information transmission method, which includes:

s110: the method comprises the following steps that a first base station receives auxiliary information of User Equipment (UE) from a second base station through an inter-base station interface, wherein the auxiliary information comprises: at least partial power saving signal configuration.

The information transmission method provided by the embodiment of the disclosure can be applied to a first base station. The first base station may be: a base station where the UE currently resides, or a base station to which the UE currently connects; or, a target base station for handover of the UE.

The current state of the UE may be any of the following: an inactive state or an idle state.

In some embodiments, the inactive state is primarily for the radio network RAN, in which no RRC connection is established between the UE and the base station, but the inactive state is transparent to the core network, which is unaware of the current lack of RRC connection between the UE and the base station.

The first base station receives the UE assistance information from the second base station through an inter-base station interface, which may be: a direct connection interface between two base stations, for example, the inter-base station interface includes but is not limited to: an XN interface. The direct connection interface between the base stations can be used for direct connection and intercommunication between the two base stations.

The XN interface comprises: an XN-C (control plane) interface and an XN-U (user plane) interface. In this embodiment, the first base station and the second base station may interact with the auxiliary information through an XN-C interface, and/or interact with the auxiliary information through an XN-U interface.

For example, the second base station stores the auxiliary information of the UE, and the second base station may be the auxiliary information of the UE acquired from the core network, or the auxiliary information received by the second base station from the UE before the first base station requests the auxiliary information.

In this way, the auxiliary information of the UE is interacted through the inter-base station interface, and at this time, the first base station does not need to request the auxiliary information of the UE from the core network, but directly receives the auxiliary information of the UE from the adjacent base station or any base station with the inter-base station interface established with the base station. The second base station may be any base station currently storing the UE assistance information. For example, the second base station may include: a base station where the UE previously resided; or anchor base station.

The auxiliary information includes: partial or full power save signal configuration for the UE. The power saving signal is configured to: one or more configuration parameters used by the UE for power save signals. The power saving signal configuration is used for controlling the power saving signal usage of the UE. For example, the power saving signal configuration may be used to control the behavior of the UE and/or the behavior of the base station; for example, the base station is controlled to issue a power saving signal, frequency and/or power of issuing the power saving signal, and the UE is controlled to monitor the power saving signal or frequency of monitoring the power saving signal.

For example, the power saving signal configuration includes, but is not limited to, at least one of:

a support configuration to indicate whether the UE supports use of power save signals;

a time domain configuration comprising at least: a start time domain configuration used by the power save signal.

The starting temporal configuration includes, but is not limited to:

the power saving signal uses an offset of a start time with respect to a reference time point.

The reference time point includes: the start time of PO and/or the end time of PO.

In some embodiments, the time-domain configuration further comprises at least one of:

time domain offset of two adjacent power saving signals;

the number of DRX cycles on which a single power-saving signal acts;

after determining the power saving signal configuration of the UE, the first base station may determine, according to the power saving signal configuration, that the UE is maintained in an awake state in one or more awake periods in the DRX cycle in which the power saving signal acts, and at this time, may issue a paging message to page the UE, or issue a Downlink transmission that needs to be received by the UE on a Physical Downlink Control Channel (PDCCH). The downlink transmission includes but is not limited to: downlink signaling and/or downlink data.

If the UE is in the idle state, the paging message may be sent by the core network. If the UE is in the inactive state, the paging message is issued by a wireless network, wherein the wireless network is a network comprising access network elements such as a base station and the like.

In the embodiment of the application, the first base station can directly receive the auxiliary information from the second base station by using the inter-base station interface, and compared with the method for requesting the auxiliary information of the UE from the core network, the method reduces the transmission path length of the auxiliary information, reduces the time delay of the first base station for acquiring the auxiliary information of the UE, and reduces the number of signaling interaction times and signaling overhead between the wireless network and the core network.

In some embodiments, the power saving signal is configured to indicate at least one of:

whether the UE supports the use of power saving signals in an inactive state;

whether the UE supports the use of power saving signals in an idle state;

whether the UE desires use of a power save signal in an inactive state;

whether the UE desires use of power save signals in a non-idle state;

time domain configuration of the power saving signal when the power saving signal is used in an inactive state;

and when the power-saving signal is used in an idle state, the time domain configuration of the power-saving signal.

In some embodiments, the power saving signal configuration includes at least one of the following:

an identifier for identifying whether the UE supports power saving signals in an inactive state;

an identifier for identifying whether the UE supports power saving signals in an idle state;

an identifier for identifying whether the UE desires to use the power saving signal in the inactive state;

an identification for identifying whether the UE desires to use power save signals in a non-idle state;

a time domain configuration for identifying a power save signal when used in an inactive state;

for identifying a time domain configuration of the power save signal when the power save signal is used in an idle state.

In some embodiments, the first base station is provided with a corresponding relationship between the time domain configuration of the power saving signal corresponding to the use of the power saving signal in the inactive state and the identifier, so as to determine the time domain configuration of the power saving signal when the power saving signal is used in the inactive state according to the received identifier of the time domain configuration of the power saving signal when the power saving signal is used in the inactive state. The correspondence between the time domain configuration of the power saving signal and the identifier when the power saving signal is used in the inactive state may be specified based on a protocol or obtained from any other network device, such as a core network or other base station.

In some embodiments, the first base station is provided with a corresponding relationship between the time domain configuration of the power saving signal corresponding to the power saving signal used in the idle state and the identifier, so as to determine the time domain configuration of the power saving signal used in the idle state according to the received identifier of the time domain configuration of the power saving signal used in the idle state. The correspondence between the time domain configuration of the power saving signal and the identifier when the power saving signal is used in the idle state or the inactive state may be specified based on a protocol or obtained from any other network device, such as a core network or other base station. In some embodiments, the identifier is the power save signal configuration itself.

For example, some UEs support the power saving signaling in the inactive state, and some UEs do not support the power saving signaling in the inactive state, at this time, whether the power saving signaling in the inactive state is supported or not may be indicated by one or more bits in the power saving signaling.

Similarly, some UEs support the power saving signaling in the idle state, and some UEs do not support the power saving signaling in the idle state, at this time, whether the power saving signaling in the idle state is supported or not may be indicated by one or more bits in the power saving signaling.

In some embodiments, whether the UE supports the use of power save signals may be dependent on the hardware of the UE.

Some UEs support the use of the power saving signal in the inactive state and/or the idle state, but the UE may provide the use of the power saving signal in the idle state and/or the inactive state according to a self-set load rate, a data transmission amount, and/or a UE type, while reducing power consumption and transmission delay as much as possible.

For example, the UE may determine whether use of a power save signal is desired based on the current amount of power remaining. For example, if the current remaining power is lower than or equal to the power threshold, the power saving signal is indicated to be expected to be used in the idle state and/or the inactive state by the power saving signal configuration, so as to further save power.

For another example, if the UE determines that the remaining power of the UE is higher than the power threshold, the UE is expected not to use the power saving signal in the idle state and/or the inactive state through the power saving signal configuration, so as to reduce the delay of the uplink transmission and/or the downlink transmission of the UE.

The time domain configuration of the power saving signal may be a time domain resource directly or indirectly indicating the use of the power saving signal, a frequency of transceiving the power saving signal in the time domain, or the like.

In some embodiments, the power saving signal configuration may further include: the frequency domain configuration of the power saving signal, for example, the UE receives a bandwidth Part (BWP) of the power saving signal issued by the base station or a Resource Element (RE) for transmitting the power saving signal.

In still other embodiments, the power saving signal configuration may also be: a power configuration, e.g., a received power configuration in which the UE receives the power save signal. If some UE has strong receiving capability, the transmitting power of the base station for transmitting the power-saving signal can be relatively smaller; however, in order to ensure the reception power of the UE, the base station needs to appropriately increase the transmission power of the power saving signal when transmitting the power saving signal, or accumulate power by way of diversity gain such as space diversity and/or frequency diversity so as to achieve the minimum reception power defined by the reception power configuration for the UE to receive the power saving signal.

In some embodiments of the present disclosure, the power saving signal configuration may be related to the capability of the UE. Different types of UEs have different terminal capabilities, for example, some UEs have a large number of antennas and strong receiving capability, and have a spatial diversity receiving capability, so that UEs with different capabilities have omitted signal configurations adapted thereto.

In some embodiments, the time domain configuration of the power save signal comprises: a starting time domain configuration of the power saving signal.

The start time domain configuration of the power saving signal may be used to limit a start time of the UE using the power saving signal, for example, a start time of the UE receiving the power saving signal sent by the base station. Assuming that the power saving signal is used by the UE within a time range, if the length of the time range is determined, the specific location of the time range on the time domain depends on the initial time domain configuration of the power saving signal. For example, the length of the time range may be a preset length, a length specified by a protocol, or a length negotiated between the UE and the base station.

In some embodiments, the starting temporal configuration herein may include:

time domain resource configuration, the starting time of different time domain resources being different, for example, the starting time domain configuration may include: resource identification of time domain resources. For example, the time domain resources include, but are not limited to, symbols, minislots, slots, or subframes, etc.

In still other embodiments, a starting time domain position of the power save signal is offset from a reference time point.

The time domain configuration of the reference signal is indirectly indicated by means of such an offset.

In the communication process between the UE and the base station, some signals are periodically transmitted, and the configuration in the time domain is relatively fixed, for example, the time domain configuration of the PO or the time domain configuration of the CSI-RS.

In the application, the time domain configuration of the reference signal is indirectly indicated through the offset value, and the indication of the offset value can simplify the indication and reduce the bit overhead compared with the direct indication of the resource identifier.

The offset here may include: one or more time domain units, which may be: one or more symbols.

In one embodiment, the time domain location of the power save signal is offset from a paging occasion.

In some embodiments, the size of the offset value is UE type dependent. The UE of a certain type receives the paging message and the power saving signal by the same receiver or processor, so the initial time domain configuration of the power saving signal may be closer to the PO of the paging message in the time domain; because the receiver or processor has already been woken up. In other embodiments, if there are different receivers or processors for the UE of a certain type to receive the paging message and the power saving signal, the initial time domain configuration of the power saving signal may be further from the PO of the paging message in the time domain to ensure successful reception of the power saving signal, so that the terminal has enough time to wake up the receiver of the power saving signal to enter the state of receiving the power saving signal. The deviation between the start time of the power saving signal and the PO in the time domain can be represented by the magnitude of the offset.

In some embodiments, the assistance information comprises at least one of:

a paging probability of the UE;

mobility information of the UE;

indication information of enhanced coverage characteristics of the UE.

The paging probability may be a UE paged frequency;

the time domain configuration of the power saving signal when the power saving signal is used in an idle state.

In some embodiments, the time domain configuration of the power saving signal when the power saving signal is used in the inactive state is a parameter value of the time domain configuration of the power saving signal when the power saving signal is used in the inactive state.

In some embodiments, the time domain configuration of the power saving signal when the power saving signal is used in the inactive state is a parameter value of the time domain configuration of the power saving signal when the power saving signal is used in the idle state.

In some embodiments, the time-domain configuration of the power-saving signal when the power-saving signal is used in the inactive state is a parameter for calculating a parameter value of the time-domain configuration of the power-saving signal when the power-saving signal is used in the inactive state.

In some embodiments, the time-domain configuration of the power-saving signal when the power-saving signal is used in the inactive state is a parameter for calculating a parameter value of the time-domain configuration of the power-saving signal when the power-saving signal is used in the idle state.

The auxiliary information carries paging probability, mobility information and indication information for enhancing the coverage characteristic, so that the density of the PO on the time domain can be configured according to the paging probability when the UE is paged subsequently; and/or, determining a paging space range according to the mobile information; and/or determining whether to adopt a coverage enhancement mode for paging according to the coverage enhancement characteristic.

For example, for an idle UE, the paging space may be a Tracking Area (TA), and if the UE is found to have a smaller mobility range than the TA based on the mobility information, the paging message may be sent only in a range where the UE is frequently active, rather than paging the UE in the entire TA, in order to reduce signaling overhead. The range in which the UE is frequently active may be less than the TA of the UE.

For another example, for a UE in an inactive state, the paging space may be the entire RAN Notification Area (RNA), and if the UE is found to have a smaller moving range than the notification area based on the moving information, the paging message may be sent only in a range where the UE is frequently active, rather than paging the UE in the entire TA, in order to reduce signaling overhead. The range in which the UE is frequently active may be smaller than the notification zone of the UE.

For example, in order to ensure successful reception of the paging message by the UE, whether to configure an enhanced coverage resource for transmitting the paging message may be determined according to enhanced coverage characteristics of the UE. The enhanced coverage resources include, but are not limited to, at least one of:

time domain resources;

frequency domain resources;

and (4) spatial domain resources.

For example, a paging message may be sent on m resources before the enhanced coverage resource is not configured, and a paging message to page the UE may be sent on m + n resources after the enhanced coverage resource is configured. Where m and n are both positive integers. By enhancing the configuration of the coverage resources, the probability of success of paging of the UE can be improved.

In some embodiments, as shown in fig. 3A, the method further comprises:

s100: and sending the request information to the second base station through the interface between the base stations. The request information is used for requesting auxiliary information of the UE from the second base station; of course, the request information may be sent to the second base station through the inter-base station interface, and the second base station may return the auxiliary information to the first base station through the inter-base station interface, or may transmit the auxiliary information to the first base station through a backhaul link or other manners. I.e. where the request message sent by the inter-base station interface to the second base station can be used alone. The request information is for requesting assistance information from the second base station.

As shown in fig. 3B, the S110 includes: s111;

s111: and the first base station receives the auxiliary information sent according to the request information from the second base station through an inter-base station interface.

In some embodiments, the second base station may actively send assistance information to the first base station, e.g., the UE is handed over from the second base station to the first base station; the second base station, serving as an anchor base station, may actively synchronize the UE auxiliary information to the target base station (i.e., the first base station), and at this time, the first base station may not send the request information to the second base station.

In some cases, the second base station may not know which base station the first base station is specifically, or the second base station may not synchronize the UE assistance information to the first base station, but the first base station may actively send a request message to request the UE assistance information if the first base station wants to know the UE assistance information. At this time, the assistance information received in step S110 is the assistance information returned by the second base station triggered by the request information.

In some embodiments, the assistance information is sent by the second base station based on a request of the first base station; or, the assistance information is transmitted by the second base station based on protocol specification.

In some embodiments, the S100 may include:

and sending a request carrying the request information for acquiring the UE context to the second base station through an interface between the base stations.

In an embodiment of the present application, the obtain UE Context Request (Retrieve UE Context Request). The request for obtaining the UE context here is a request that the target base station requests the anchor base station for the UE context when the UE moves to a new target base station. In the embodiment of the present application, the request for obtaining the UE context carries the request information, for example, the request information may be indicated by one or more bits in the request for obtaining the UE context. For example, the request information may be carried by reserved bits or reserved IEs in the UE. In the embodiment of the application, the UE context request is obtained in a multiplexing mode to carry the request information, a signaling transmitted by an interface between the base stations is not required to be specially configured for the request information, and the number of signaling interaction times and signaling overhead between the base stations can be reduced.

In some embodiments, the S110 may include:

and the first base station receives a request response carrying the auxiliary information for acquiring the UE context from the second base station through an interface between the base stations.

In some embodiments, the second base station may actively transmit the assistance information of the UE to the first base station through the inter-base station interface, and the message for transmitting the assistance information may be any message that can be transmitted through the inter-base station interface. In the embodiment of the present application, the request response for obtaining the UE context carries the auxiliary information. The auxiliary information can be carried by one or more newly-added bits or reserved bits in the response of the request for obtaining the UE context, so that the auxiliary information can be transmitted by multiplexing the response of the request for obtaining the UE context which can be transmitted by the interface between the base stations, and the signaling transmitted by the interface between the base stations does not need to be specially configured for the auxiliary information, so that the signaling interaction times and the signaling overhead between the base stations can be reduced.

In some embodiments, the get UE context request response is returned based on the get UE context request of the first base station;

alternatively, the first and second electrodes may be,

the get UE context request response is sent by the second base station based on protocol specifications.

For example, in some cases, the get UE context request response may be sent by the second base station without being requested by the first base station, and thus the get UE context request response may be sent actively by the second base station, which is actively sent according to protocol specifications.

In some cases, of course, if the protocol does not specify that the second base station needs to actively transmit, or the second base station is not ready to transmit, the first base station sends a request for obtaining the UE context, and the response for obtaining the context at this time is returned according to the request for obtaining the UE context.

In some embodiments, the get UE context request response further comprises: a context of the UE;

the auxiliary information and the acquired UE context are located in different information elements IE;

alternatively, the first and second electrodes may be,

the auxiliary information and the UE context are located in the same IE.

The auxiliary information and the UE context may be located in the same IE or different IEs, and this may be configured according to communication requirements.

For example, in some embodiments, the get UE context request response is newly added with an IE for carrying UE assistance information.

This IE is dedicated to carrying the auxiliary information. And the UE context is still carried in an IE which is preset to carry the UE context in the request response for obtaining the UE context.

In one embodiment, this IE may be referred to as a UE Radio Capability for Paging IE.

For another example, some reserved bits or reserved fields exist in the IE intended to carry the UE context, and the auxiliary information may also be carried in the reserved bits or reserved fields in the IE intended to carry the UE context.

In some embodiments, the S110 may include:

and the first base station receives a wireless network RAN paging message carrying the auxiliary information from a second base station through an interface between the base stations.

The UE assistance information is not limited to the UE context request response, and may also be a paging message.

For example, the paging message for the inactive UE is formed and issued by the base station of the RAN. For example, if the UE is in an inactive state and the base station receives a paging trigger event such as information to be delivered to the UE, the base station where the UE resides or is connected before, that is, the anchor base station, may form and broadcast the RAN paging message, and forward the RAN paging message to other base stations in the notification area (RNA) or in the paging range smaller than the RNA. In this embodiment, at this time, the second base station directly carries the auxiliary information in the RAN paging message, so that the first base station receives the auxiliary information of the UE while receiving the RAN paging message for paging the UE.

For example, the RAN paging message further includes: radio paging information for paging the UE;

the radio paging information and the auxiliary information are located in different IEs;

example 1:

in the narrowband communication of R15, only the application of the idle power saving signal is considered. At this time, the UE reports the auxiliary information supported by the power saving signal to the base station through the UE capability (UE-radio paging info) in the connected state, and then the base station notifies the core network through a UE capability information notification (UE capability info notification) message sent to the core network. Then, the core network adds UE-radio capability for Paging, which includes UE capability, to the Paging message sent to the RAN. If the mechanism is introduced into the non-activated state in the NR, the base station needs to acquire the UE capability if it needs to initiate a paging message to the UE. The method and the device protect the auxiliary information supported by the UE for the power-saving signal transmitted during the interaction between the interfaces of the base station, so that the base station is prevented from going to a core network to acquire the information.

In some cases, the inter-base station interaction message RETRIEVE UE CONTEXT REQUEST adds the UE's response to the assistance information supported by the power save signal. As an embodiment, the request identifies that assistance information supported by the UE for the power saving signal is added in a response to acquire the context.
