Description

Transmission method, transmission device, network node, terminal and readable storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a transmission method, a transmission device, a network node, a terminal and a readable storage medium.

Background

Two types of measurement gaps are introduced in a New Radio (NR) system, namely a measurement gap at the level of a terminal (UE) and a measurement gap at the level of a Frequency Range (FR). The measurement gaps at the frequency range level are the gap (perFR 1, gapFR 1) for carrier measurement on FR1 and the gap (perFR, gapFR 2) for carrier measurement on FR2, respectively. Whether the terminal is capable of supporting the measurement gaps perFR and perFR is an alternative capability. Supporting independent measurement gaps on FR1 and FR2 is very useful for some deployments of NR systems. Under the deployment condition of the FR1 and FR2 combined networking, if the terminal does not determine whether the terminal supports an independent measurement gap, the terminal can only perform time-sharing measurement on the carriers on the FR1 and the FR2 in the measurement gap at the UE level, so that the mobility performance on the FR1 can be influenced by the measurement time delay on the FR 2.

In order to better understand the technical solutions provided by the embodiments of the present application, the following explains related concepts possibly related to the embodiments of the present application.

Dual connection (Dual Connectivity, DC):

The dual connectivity provides resources for the UE to two network nodes (access network elements), one of which is called a Master Node (MN) and the other is called a Secondary Node (SN). At each network node, a carrier aggregation technique (Carrier Aggregation, CA) is used, i.e. a series of serving cells, also called cell groups (cell groups), controlled by the node are configured for the UE. MN controls the primary cell Group (MASTER CELL Group, MCG) and SN controls the secondary cell Group (Secondary Cell Group, SCG). Each Cell group contains one special Cell (SPECIAL CELL, SPCELL) and a series of Secondary cells (scells). The special cell is called a primary cell (PRIMARY CELL, PCELL) in the MCG, and the special cell is called a primary secondary cell (Primary Secondary Cell, PSCell) in the SCG. SpCell uses the primary carrier in one cell group, while other secondary cells use the secondary carrier, and resource scheduling within one cell group is performed by SpCell.

Measurement gap (measurement gap):

Mobility management is an important function of wireless communication. In a mobile communication system, cell handover is a key process for ensuring continuity of user services. The layer 3 radio resource management (Radio resource management, RRM) measurements provide important support for cell handover, and the network can make cell handover decisions based on the layer 3 RRM measurements. The RRM measurements of layer 3 are also used for other purposes, such as the network offloading (offloading) the terminal to other carriers and cells in order to achieve load balancing on the different carriers and cells, and this decision can also be based on RRM measurements.

Layer 3 measurements often require measurement gaps such as Inter-frequency (Inter-frequency) measurements and Inter-system (Inter-RAT) measurements. For Intra-frequency (Intra-frequency) measurements, if the Synchronization SIGNAL AND PBCH block (SSB) is not completely within the active Bandwidth Part (BWP), then measurements need to be made within the measurement gap. Within the measurement gap, the terminal cannot be scheduled.

2 Types of measurement gaps are introduced in the NR, the UE-level measurement gap (per-UE gap) and the frequency range-level measurement gap (per-FR gap). The UE-level measurement gap is used to measure carriers in all frequency ranges including FR1 and FR 2. The measurement gaps at the frequency range level are the gap (perFR 1, gapFR 1) for carrier measurement on FR1 and the gap (perFR, gapFR 2) for carrier measurement on FR2, respectively.

In addition, the following table sets forth what measurement gap (gap) is configured by which network node under different DC scenarios.

MR-DC	Per-UE gap	Per-FR1 gap	Per-FR2 gap
				(NG)EN-DC	MN	MN	SN
NE-DC	MN	MN	MN
				NR-DC	MN	MN	MN

Whether the terminal is capable of supporting the measurement gaps perFR and perFR is an alternative capability. This capability is indicated by an independent measurement gap configuration (independentGapConfig).

The UE supports independent measurement gaps on FR1 and FR2, which is very useful for some deployments of NR systems. The measurement delay on the FR2 carrier is high because of the need for scanning of the receive beam. In the deployment situation of the FR1 and FR2 joint networking, if an independent measurement gap is not supported, the terminal can only perform measurement of the FR1 and FR2 carriers in a time-sharing manner in the measurement gap of the UE level. Thus, the mobility performance on FR1 is also affected by the measurement delay on FR2, eventually resulting in a poor user experience. In addition, in the case where measurement of the FR1 carrier does not require a measurement gap and measurement of the FR2 carrier requires a measurement gap, if the terminal does not support an independent measurement gap, then the serving cell on the FR1 carrier cannot schedule the terminal in the measurement gap of the FR2 carrier, but if the terminal supports an independent measurement gap, then the serving cell on the FR1 carrier can always schedule the terminal, thereby improving the performance of the system.

The terminal capability independentGapConfig in the correlation mechanism is an indication of the UE level (per UE), i.e. regardless of the current terminal configuration, such as the configuration of the band combination, if the terminal reports support for this capability, the terminal needs to be able to support measurements of 2 independent measurement gaps over different Frequency Ranges (FR) FR1 and FR 2.

The terminal can support independentGapConfig this capability, either based on the fact that the radio frequency links of FR2 and FR1 are independent, the baseband resources are independent, or the measurements of FR1 and FR2 are dedicated resources. With the advancement of terminal design and efficient use of baseband resources, the baseband resources of FR1 and FR2 need to be able to be dynamically shared. Thus, in the case of higher-order band combining (e.g., the terminal is currently configured with 8 subcarriers), the terminal does not necessarily have enough baseband resources to support measurement of 2 independent measurement gaps on FR1 and FR 2. That is, the terminal can support the configuration of 2 independent measurement gaps on FR1 and FR2 in some band combinations, while not supporting this capability in some band combinations.

The transmission method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a transmission method according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

Step 201, the first node decides to request the terminal to report the first capability.

Alternatively, the first node may be a primary node (MN) or a Secondary Node (SN). For example, the first node may be the MN, that is, the MN decides to request the terminal to report the first capability, and in some embodiments, may also be expressed as the MN decides to configure the terminal to report the first capability. That is, the first node itself can decide whether to request the terminal to report the first capability.

Wherein the first capability is used to indicate whether the terminal supports independent measurement gaps.

Step 202, the first node sends first indication information to the terminal, or the first node sends the first indication information to the terminal through a second node.

The first indication information is used for requesting the first capability of the terminal, namely, whether the request terminal supports the capability of independently measuring the gap.

Optionally, the first node may send the first indication information to the terminal by itself, so as to request the terminal to report the first capability. Or the first node may send the first indication information to the terminal through the second node, for example, the first node may send second indication information to the second node, where the second indication information is used to request the second node to send first indication information that requests the first capability to the terminal.

In the embodiment of the present application, when deciding to request the terminal to report the first capability of whether the terminal supports the independent measurement gap, the first node may send the first indication information for requesting the first capability to the terminal, or the first node may send the first indication information to the terminal through the second node. Furthermore, it is defined that in the dual-connectivity scenario, the network node can determine whether to request the first capability of the terminal, and in the case of determining to request the terminal to report the first capability, directly or indirectly send the indication information to the terminal to obtain whether the terminal supports the capability of the independent measurement gap, so that the network node can obtain the measurement gap capability (per-FR gap capability) of the frequency range level with higher granularity, so that the network node can provide suitable measurement gap configuration, and improve the mobility performance of the terminal and the throughput of the system, thereby improving the user experience.

Optionally, the first node sends the first indication information to the terminal through a second node, including:

The first node sends second indication information to a second node; wherein the first indication information is transmitted based on the second indication information.

In an exemplary embodiment, taking the first node as a master node and the second node as an auxiliary node, when the master node decides to request the terminal to report the first capability, the master node may send second indication information to the auxiliary node, where the second indication information is used to request or instruct the auxiliary node to send the first indication information to the terminal, where the first indication information is used to request or instruct the terminal to report the first capability, that is, whether the terminal supports the capability of independently measuring the gap, and further, the auxiliary node sends the first indication information to the terminal.

In the embodiment of the application, the first node can indirectly send the first indication information to the terminal through the second node, and the acquisition of the independent measurement gap capability of the terminal is realized through the interaction between the first node and the second node, so that the acquisition mode of the independent measurement gap capability of the terminal is more flexible.

In this embodiment, after receiving the first indication information, the terminal may report the first capability directly to the first node, or may report the first capability to the first node through the second node.

Optionally, after the first node sends the first indication information to the terminal, the method further includes:

the first node sends third indication information to the second node, wherein the third indication information is used for indicating that the first node has sent the first indication information to the terminal.

In this embodiment, when the first node determines that the first capability is requested to be reported by the terminal, and the first node directly sends the first indication information to the terminal, the first node may also send third indication information to the second node, where the third indication information is used to indicate that the first node has sent the first indication information for requesting the first capability of the terminal to the terminal, so that the first node can also inform the second node of the behavior of the first node through the third indication information, so that the second node can learn the configuration of the first node, and can also learn whether the terminal supports the independent measurement gap.

In the embodiment of the application, in a new air interface-new air interface dual connection (NR-NR Dual Connectivity, NR-DC) mode or a new air interface-evolved universal wireless access network dual connection (NR-Evolved Universal Terrestrial Radio Access Network Dual Connectivity, NE-DC) mode, the first node is a main node, the second node is an auxiliary node, and the main node sends the first indication information to a terminal;

In a universal wireless access network-new air interface dual-connection (Next Generation Radio Access Network Evolved Universal Terrestrial Radio Access-NR Dual Connectivity,NGEN-DC) mode of the next generation wireless access network evolution, the first node is an auxiliary node, and the second node is a main node; or the first node is a main node, the second node is an auxiliary node, and the first node sends the first indication information to the terminal through the second node.

In the NGEN-DC mode, if the first node is the auxiliary node and the second node is the main node, the auxiliary node may directly send the first indication information for requesting the terminal to report the first capability to the terminal, or the auxiliary node may send the first indication information to the terminal through the main node when the auxiliary node decides to request the first capability to the terminal. Or in NGEN-DC mode, the first node can also be a main node, and the second node is an auxiliary node, in which case, the main node sends the first indication information to the terminal through the auxiliary node.

For the NR-DC and NE-DC scenes, the master node can be agreed to determine whether to report the first capability of the request terminal or not all the time, and the master node directly sends the first indication information for reporting the first capability of the request terminal to the terminal.

For a better understanding, the technical solutions provided by the present application are described below by means of several specific embodiments.

Embodiment one:

Step 1.1: the MN decides to request (or configure) the terminal to report a first capability, which is used to indicate whether the terminal supports independent measurement gaps;

Step 1.2: the MN sends first indication information to the terminal, wherein the first indication information is used for requesting the first capability of the terminal, namely, the first capability is reported by the terminal;

Step 1.3: the MN sends third indication information to the SN, wherein the third indication information is used for indicating that the MN has sent the first indication information.

It should be noted that, for NE-DC and NR-DC scenarios, since both per-UE gap and per-FR1 gap and per-FR2 gap are MN configured, only MN needs to know whether the terminal supports independent measurement gaps, SN does not need to obtain this capability, and step 1.3 does not need to be executed in NE-DC and NR-DC scenarios; for NGEN-DC scenario, however, because per-FR2 gap is configured by SN, SN needs to know whether the terminal supports independent measurement gaps, step 1.3 above needs to be performed to let SN know MN configuration.

Embodiment two:

Step 2.1: the SN decides to request (or configure) the terminal to report a first capability, which is used to indicate whether the terminal supports an independent measurement gap;

Step 2.2: the SN sends second indication information to the MN, wherein the second indication information is used for requesting the MN to send first indication information to the terminal, and the first indication information is used for indicating or requesting the terminal to report the first capability;

step 2.3: the MN sends first indication information to the terminal.

Embodiment III:

Step 3.1: the SN decides to request (or configure) the terminal to report a first capability, which is used to indicate whether the terminal supports an independent measurement gap;

step 3.2: the SN sends first indication information to the terminal, wherein the first indication information is used for indicating or requesting the terminal to report the first capability;

step 3.3: the SN sends third indication information to the MN, wherein the third indication information is used for indicating that the SN has sent the first indication information to the terminal.

Embodiment four:

Step 4.1: the MN decides to request (or configure) the terminal to report a first capability, which is used to indicate whether the terminal supports independent measurement gaps;

Step 4.2: the MN sends second indication information to the SN, wherein the second indication information is used for requesting the SN to send first indication information to the terminal, and the first indication information is used for indicating or requesting the terminal to report the first capability;

Step 4.3: the SN sends first indication information to the terminal.

It should be noted that, for NR-DC and NE-DC scenarios, it may be agreed that the MN always decides to trigger the request and send the first indication information, i.e. embodiment one; for NGEN-DC scenarios, then either embodiment two or embodiment three or embodiment four may be performed.

Further, in the embodiment of the present application, after receiving the first indication information sent by the first node or the second node, the terminal reports the first capability based on the first indication information, and the first node and the second node can forward the first capability.

Optionally, the method further comprises:

In case a first message is transmitted over a signaling radio bearer (SIGNALING RADIO BEARER, SRB) 1, the first node sends the first capability to the second node; wherein the first message carries the first capability.

In this embodiment, the terminal transmits the first message to the lower layer (lower layers) through the SRB1, where the first message carries the first capability, that is, the terminal reports the first capability to the first node, and when the first node is the primary node, the primary node can forward the first capability to the second node (that is, the secondary node), so as to ensure that the second node can also know whether the current configuration of the terminal supports an independent measurement gap, and further the network node can also provide an appropriate measurement gap configuration, thereby improving the mobility performance of the terminal and throughput of the system, and further improving user experience.

Optionally, the first node sends the first capability to the second node, which may specifically include:

the first node sends the first capability to the second node in case the first capability indicates that the terminal supports independent measurement gaps.

For example, in the case that the first capability indicating terminal supports the independent measurement gap, the primary node forwards the first capability to the secondary node, in other words, if the first capability indicating terminal does not support the independent measurement gap, the primary node may not forward the first capability to the secondary node.

Or the first node sends the first capability to the second node, which may specifically further include:

In NGEN dual connectivity mode, the first node sends the first capability to the second node.

Illustratively, in NGEN-DC mode, the primary node, upon receiving a first capability reported by the terminal, forwards the first capability to the secondary node.

Optionally, the method may further include:

In the case that a second message is transmitted to a lower layer through SRB3, the first node transmits the first capability to the second node; the second message carries the first capability, the first node is an auxiliary node, and the second node is a main node.

For example, if the terminal configures SRB3, the terminal transmits the second message to the lower layer through SRB3, so as to send the first capability to the auxiliary node, and the auxiliary node may further forward the first capability to the main node, so as to ensure that the main node can know whether the current configuration of the terminal can support independent measurement gaps, and further the network node can also provide appropriate measurement gap configuration, thereby improving the mobility performance and system throughput of the terminal.

It is noted that it may be agreed that the terminal only reports said first capability via SN in NGEN-DC mode.

Optionally, the terminal may also report the first capability through the primary node and the secondary node simultaneously. Illustratively, the terminal submits a first message to the lower layer for transmission over SRB1, the first message carrying the first capability; if the SRB3 is configured, the terminal may further submit the second message to the lower layer for transmission through the SRB3, where the second message carries the first capability, and further, the first capability sent by the terminal may be directly received between the first node and the second node, so that forwarding of the first capability is not required.

In addition, under the condition that the first node does not receive the first capability, the first node determines that the terminal does not support the independent measurement gap under the current configuration, or the first node determines whether the terminal supports the independent measurement gap based on whether the terminal supports the independent measurement gap in the indication in the reporting process of the terminal capability.

For example, taking the first node as an auxiliary node, if the auxiliary node does not receive the first capability sent by the terminal or does not receive the first capability forwarded by the master node, the auxiliary node defaults that the terminal does not support the independent measurement gap under the current configuration, or the auxiliary node determines whether the terminal supports the independent measurement gap according to whether the terminal supports the independent measurement gap indicated by independentGapConfig in the reporting process of the terminal capability.

In the embodiment of the application, the first capability is used for indicating whether the terminal supports independent measurement gaps under the current configuration.

Optionally, the current configuration includes at least one of:

parameters of carrier aggregation (Carrier Aggregation, CA);

parameters of a Multi-radio dual connection (Multi-Radio Dual Connectivity, MR-DC);

At least one of addition, release, and change of a secondary cell (SCell);

At least one of addition, release, change of primary and secondary cells (pscells);

At least one of addition, release, change of the conditional primary and secondary cells (Conditional PSCell);

Layer 1 (L1) parameters, such as Multiple-Input Multiple-Output (MIMO) related parameters.

Optionally, the first capability and/or the first indication information is not related to a reference signal, where the first capability is used to indicate whether the terminal supports measurement of all reference signals or independent measurement gaps of a first reference signal; wherein the first reference signal is a reference signal other than the following reference signals:

synchronization SIGNAL AND PBCH block (SSB);

Channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS);

positioning reference signal (Positioning REFERENCE SIGNAL, PRS).

The first capability is illustratively independent of the reference signals, e.g. the first capability is used to indicate whether the terminal supports independent measurement gaps, which may be used for measuring all reference signals or for measuring other reference signals than SSB, CSI-RS, PRS.

The first indication information may also be irrelevant to the reference signals, where the first indication information is used to request the terminal to report whether an independent measurement gap is supported, where the independent measurement gap may be used to measure all the reference signals, or where the independent measurement gap is used to measure other reference signals except SSB, CSI-RS, PRS.

Optionally, the first capability and/or the first indication information is related to a reference signal, where the first capability is used to indicate whether the terminal supports an independent measurement gap for measuring a second reference signal, and the second reference signal includes at least one of:

SSB；

CSI-RS；

PRS。

Optionally, in an embodiment of the present application, the method further includes at least one of:

in the switching process, the first node sends the first capability to a third node, wherein the first node and the third node are both master nodes; wherein the third node is a target node of the switching process;

In the process of changing the auxiliary node, the first node sends the first capability to a third node, wherein the first node and the third node are both auxiliary nodes; the third node is a target node of the auxiliary node changing process.

For example, if the primary node switches when receiving the first capability sent by the terminal or forwarded by the secondary node, the current primary node sends the first capability to the switched primary node in the primary node switching process, for example, the source PCell sends the first capability to the target PCell.

It should be noted that, the specific implementation process may refer to the description in the embodiment described in fig. 2 and will not be repeated herein when the terminal receives the first indication information sent by the first node or receives the first indication information sent by the first node through the second node.

Step 302, the terminal reports the first capability.

In the embodiment of the application, after the terminal receives the first indication information requesting to report the first capability, the terminal reports the first capability based on the first indication information, namely whether the terminal reports the independent measurement gap is supported or not, so that the network node can obtain the measurement gap capability (per-FR gap capability) with higher granularity of the frequency range level, and in this way, the network node can provide proper measurement gap configuration based on whether the terminal supports the independent measurement gap or not, thereby improving the mobility performance of the terminal and the throughput of the system and improving the user experience.

Optionally, the terminal reports the first capability, including at least one of the following:

The terminal reports the first capability through a main node;

and the terminal reports the first capability through the auxiliary node.

The master node may be a first node or a second node; if the main node is the first node, the auxiliary node is the second node, and if the main node is the second node, the auxiliary node is the first node.

Optionally, the terminal reports the first capability through a master node, including:

The terminal transmits a first message to a lower layer through SRB1, wherein the first message carries the first capability; wherein the master node is the first node or the second node.

For example, the master node is a first node, and the first node sends first indication information to the terminal, and the terminal transmits a first message to the lower layer through the SRB1 based on the first indication information, where the first message carries the first capability, that is, the terminal reports the first capability through the master node.

Optionally, the terminal transmits the first message to the lower layer through SRB1, including:

And under the condition that the terminal receives the first indication information sent by the master node, the terminal transmits a first message to a lower layer through SRB 1.

For example, the master node is a first node, that is, the first node directly sends the first indication information to the terminal, and the terminal transmits a first message to the lower layer through the SRB1 to report the first capability to the master node. Or the master node is a second node, for example, the auxiliary node sends first indication information to the terminal through the master node, and the terminal transmits a first message carrying the first capability to the lower layer through the SRB 1.

That is, if the first indication information is transmitted to the terminal through the master node, the terminal delivers the first message to the lower layer through the SRB1 for transmission.

In the embodiment of the present application, the terminal may also report the first capability through the auxiliary node.

Optionally, the terminal reports the first capability through the auxiliary node, including:

In the case that the terminal is configured with the SRB3, the terminal transmits a second message to a lower layer through the SRB3, wherein the second message carries the first capability; wherein the secondary node is the first node or the second node.

For example, after receiving the first indication information sent by the first node or the second node, if the terminal configures SRB3, the terminal may submit the second message carrying the first capability to the lower layer for transmission through SRB3, so as to report the first capability through the auxiliary node.

Optionally, in a case that the terminal is configured with SRB3, the terminal transmits a second message to a lower layer through SRB3, including:

And under the condition that the terminal receives the first indication information sent by the auxiliary node and the terminal is configured with SRB3, the terminal transmits a second message to a lower layer through the SRB 3.

For example, the secondary node directly sends first indication information for requesting the terminal to report the first capability to the terminal, or the primary node sends the first indication information to the terminal through the secondary node, if the terminal configures SRB3, the terminal may submit a second message to a lower layer through SRB3 for transmission, so as to report the first capability through the secondary node.

Optionally, the terminal reports the first capability to the auxiliary node only if the first capability indicates that the terminal supports independent measurement gaps. If the auxiliary node does not receive the first capability sent by the terminal, the auxiliary node defaults that the terminal does not support the independent measurement gap under the current configuration, or the auxiliary node determines whether the terminal supports the independent measurement gap according to whether the terminal supports the independent gap in the terminal capability reporting process.
