Detailed Description

The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The following is a brief description of the terms involved in the present application, as follows:

1. dual activation protocol stack (DualActive Protocol Stack DAPS)

The interruption time of mobility refers to the shortest time when the terminal device cannot interact with any base station for user plane packets. As described in 11.4.2.2, in the existing New Radio (NR) handover procedure, after the terminal device receives a handover command, the terminal device (UE) disconnects from the source cell and initiates a random access/synchronization procedure to the target cell, during which the data interruption time of the UE is at least as long as 5ms, and in order to shorten the interruption time of the User data, the NR introduces a New handover enhancement procedure, that is, handover based on dual active stack (DAPS handover).

The main idea of the DAPS handover is to maintain the data service with the source cell while the UE receives the handover command and initiates random access to the target cell, thereby realizing a data interruption time of 0ms in the handover process. And after receiving the DAPS switching command, the UE keeps the connection of the source cell and initiates a synchronization process to the target cell. When the synchronization process/random access is completed, the UE performs uplink data switching, that is, uplink data transmission of the UE after random access is switched from the source base station side to the target base station side. The release of the source base station protocol stack after the random access is based on the display indication of the network, that is, during the period from the random access to the release of the source base station side connection, the UE can normally receive the downlink data sent by the source cell, and can send uplink feedback related information of the downlink data to the source cell.

During the random access of the UE to the target cell, the UE can keep monitoring the radio link of the source cell, if the DAPS handover fails at this time, the UE does not successfully access the target cell, and the radio link failure does not occur in the source cell, the UE can return to the connection with the source cell, thereby avoiding the reestablishment process of the radio resource control (Radio Resource Control, RRC) connection caused by the handover failure.

On the other hand, the UE may simultaneously maintain radio link monitoring of the source cell during access to the target cell, and if a radio link failure occurs in the source cell during access to the target by the UE (the UE initiates a random access procedure to the target), the UE may release the source cell and may not initiate a connection re-establishment procedure.

Considering UE capability, the R16DAPS handover does not support configuration with DC (Dual connectivity)/CA (Carrier Aggregation ), that is, the network device needs to instruct the UE to release the current Secondary Node (SN) or Secondary cell (Scells) through signaling before configuring the DAPS handover for the UE, and re-access the corresponding delay, which has a large signaling overhead.

It should be understood that a device having a communication function in a network/system according to an embodiment of the present application may be referred to as a communication device. Taking the communication system shown in fig. 1 as an example, the communication device may include a network device and a terminal device with a communication function, where the network device and the terminal device may be specific devices described in the embodiments of the present application, and are not described herein again; the communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

In the following, by way of example, the technical solution of the present application is further described, as shown in fig. 2, which is a schematic diagram of an embodiment of a method for deactivating a cell in an embodiment of the present application, and may include:

201. under the condition that the terminal equipment meets the first condition, deactivating the first auxiliary node SN and/or a first cell; the first condition is a handover condition from a source cell to a target cell.

It is to be understood that the first condition is a handover condition from a source cell to a target cell, and may be understood as a handover condition from a source base station to a target base station.

Optionally, the first cell includes at least one of a first secondary cell SCell and a first secondary cell group SCG.

1. Optionally, the first condition includes at least one of:

(1) Receiving a switching command; for example: a radio resource control (Radio Resource Control, RRC) reconfiguration message is received.

(2) A dual active protocol stack DAPS radio data/signaling bearer configuration is received.

It is appreciated that the dual active protocol stack DAPS wireless data/signaling bearer configuration may also be referred to as a DAPS bearer. In order for the terminal device to understand whether the DAPS bearer is configured, it needs to check whether the field DAPS Config exists in RadioBearerConfig IE (Information Elements, information element) received in radio bearer configuration (radio bearconfig) or radio bearconfig 2.

(3) An uplink synchronization procedure (e.g., random access) is initiated towards the target cell.

(4) A condition reconfiguration message is received.

Optionally, the conditional reconfiguration message includes a CHO/CPAC handover command.

(5) When the condition of the condition switching (conditional handover, CHO) is satisfied.

It can be appreciated that the core idea of CHO is to let the terminal device select the target base station according to the measurement result and initiate the handover execution procedure, and initiate the random access to the target cell. Therefore, the situation that the UE fails to switch due to the change of the wireless link state can be avoided in the time of the signaling interaction between the terminal equipment UE and the source base station and the signaling interaction between the source base station and the target base station. In this way CHO improves the robustness during user switching.

It is understood that an execution condition may consist of one or two trigger conditions (e.g., CHO event A3/A5). Only a single reference signal type is supported, and at most two different trigger amounts (e.g., RSRP (Reference Signal Receiving Power, reference signal received power) and RSRQ (Reference Signal Receiving Quality, reference signal received quality), RSRP and SINR (Signal to Interference plus Noise Ratio ), etc.) may be simultaneously configured to evaluate CHO performance conditions for a single candidate cell. Illustratively, CHO conditions are met, which may be threshold values configured for network devices for RSRP and/or RSRQ; RSRP and/or SINR meet a threshold of network device configuration, etc.

(6) When the condition of conditional secondary cell group addition/replacement (conditional PScell change/addition, CPAC) is satisfied.

Illustratively, the condition of the CPAC is satisfied, which may be that RSRP (Reference Signal Receiving Power, reference signal received power) satisfies a threshold configured by the network device, RSRQ (Reference Signal Receiving Quality, reference signal received quality) satisfies a threshold configured by the network device, SINR (Signal to Interference plus Noise Ratio ) satisfies a threshold configured by the network device, or the like.

(7) When the condition switching CHO is performed.

Illustratively, the UE maintains a connection with the source base station after receiving the CHO configuration and begins evaluating CHO execution conditions of the candidate cells. If at least one CHO candidate cell satisfies the corresponding CHO execution condition, the UE separates from the source base station, applies the stored corresponding configuration for the selected candidate cell, synchronizes to the candidate cell, and completes the RRC handover procedure by sending an RRC reconfiguration complete (RRCRECONfigure) message to the target base station. After successful completion of the RRC handover procedure, the UE releases the stored CHO configuration.

(8) When performing CPAC.

And (9) receiving reconfiguration information configured with dual activation protocol stacks DAPS and CHO/CPAC.

2. Optionally, the deactivating the first secondary node SN, and/or the first cell, the behavior of the terminal device includes at least one of:

(1) The protocol stack corresponding to the first SN/first secondary cell group (Secondary Cell group, SCG) is suspended or suspended (suspend).

(2) Stopping data transmission of the first SN/first SCG/first Secondary Cell (SCell (s)); the data transmission is also understood to mean data transmission and reception.

(3) A first timer is started.

Optionally, the first timer is a T304 timer, or a newly configured timer.

(4) Listening to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) is stopped.

(5) The reception of the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) is stopped.

(6) The downlink grant (downlink Link grant) of the semi-persistent scheduling (Semi Persistent Scheduling, SPS) is released.

(7) The transmission of the uplink channel sounding reference signal (Sounding Reference Signal, SRS) is stopped.

(8) The transmission of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) is stopped.

(9) Releasing/suspending Grant of uplink pre-Configured resources (CG).

Illustratively, the UL grant of type 2 (type 2) CG is released. Suspension (Suspend) type 1 CG.

It may be appreciated that the pre-configured resources are resources for the UE to transmit uplink data, may be based on dynamic scheduling of the network device (e.g., indicated by downlink control information (Downlink Control Information, DCI)), or may be based on a periodic set of occurring uplink resources pre-configured by the network device. The upstream CG can be classified into two types, type1 and Type 2.

CG Type1 is configured by radio resource control (Radio Resource Control, RRC) parameters configured grant configuration, which may include time domain resources, frequency domain resources, demodulation reference signals (Demodulation Reference Signal, DMRS), open loop power control, modulation coding scheme (Modulation and Coding Scheme, MCS), waveform, redundancy version, repetition number, frequency modulation, hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process, and the like. After the UE receives the higher layer configuration, the UE may use the configured CG type1 resource to perform uplink data transmission, without requiring an additional activation step.

CG Type2 is also configured by RRC parameter configurable grant configuration, but does not contain information indicated in the RRC-configurable uplink grant domain, and activation of configured CG Type2 resources is indicated by configuring DCI that schedules scrambling of radio network temporary identity (Configured Scheduling Radio Network Tempory Identity, CS-RNTI), and simultaneously configuring transmission resources and transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, etc. After receiving the high-level configuration, the UE cannot use CG Type2 resources, and must wait for receiving the corresponding DCI activation instruction and configuration information before transmitting uplink data.

And (3) injection: the rrc-configurable uplink grant field in configurable grant is used to distinguish between Type1 and Type1, if this field is configured, indicating that the current configuration is CG Type1, otherwise CG Type2.

And the UE determines the HARQ process corresponding to the CG resource according to the network configuration, and starts a CG timer (CG timer) after the UE finishes uplink data transmission by utilizing a certain HARQ to carry out the corresponding CG resource. During CG timer running period, UE can not use CG resources with the same HARQ process to carry out data new transmission so as to avoid that data in HARQ buffer is covered by other data. When CG timer times out, it implicitly indicates that the data transmitted by the corresponding HARQ process has been received correctly by the network. In order to support the high latency requirements of high reliability and low latency communication (Ultra-reliable and Low Latency Communications, URLLC) traffic, URLLC enhances CG cycles, supporting traffic cycles at arbitrary slot levels (slot-levels).

(10) All SCG scells are deactivated.

It will be appreciated that the terminal device deactivates all SCG scells, i.e. all SCG scells enter a deactivated state, whatever cell state was before. Specifically, all scells of all SCGs may be activated, or at least one SCell of all SCGs may be activated, which is not limited herein.

(11) The primary and secondary cells (Primary Secondary Cell, PSCell) are deactivated.

(12) The dormant (dorman) Bandwidth portion (BWP) of the PSCell is activated.

It is understood that in (17) and (18), the object targeted may be a PSCELL and/or a part or all of a scell. RRM measurements may be either Master Node (MN) configuration or Secondary Node (SN) configuration.

202. And the terminal equipment activates the second auxiliary node SN and/or the second cell under the condition that the second condition is met.

Optionally, the second condition is that the handover from the source cell to the target cell is completed, which may also be understood as the completion of the handover from the source base station to the target base station.

Optionally, the second cell includes at least one of a second secondary cell SCell and a second secondary cell group SCG.

1. Optionally, the second condition includes at least one of:

(1) And completing the random access flow initiated to the target cell.

(2) And resolving the random access contention conflict to the target cell.
