Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a random access processing method, device and terminal. Background Art

[0002] Dual Connectivity (DC) means providing the terminal with the resources of two network nodes (access network elements), one of which is called the master node (MN) and the other is called the secondary node (SN). In each network node, carrier aggregation technology (CA) is used, that is, a series of service cells controlled by the node are configured for the terminal, also known as cell groups (cell groups). The master node controls the master cell group (MCG), and the secondary node controls the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (Scell). In MCG, the special cell is called the primary cell (PCell), and in SCG, the special cell is called the primary secondary cell (PSCell). In a cell group, the SpCell uses the primary carrier, while other secondary cells use secondary carriers.

[0003] The SCG suspended state is introduced. When the terminal has low data transmission or no data transmission on the SCG for a long time, the network can temporarily suspend the SCG instead of directly deleting the SCG and then adding it back when large data appears. The practice of temporarily suspending the SCG allows the terminal to work in a more power-saving way for a long period of time, and the SCG can be restored quickly when there is a large amount of data demand. During the standardization process, the term SCG deactivation is used, that is, the SCG activation / deactivation state. SCG deactivation can also be initiated for the purpose of terminal overheating or power saving. The terminal behavior and network control method in the SCG deactivation state are currently being discussed. It can be determined that during the SCG deactivation period, the terminal does not monitor the Physical Downlink Control Channel (PDCCH) on the SCG and does not transmit the Physical Uplink Shared Channel (PUSCH) and the Channel Sounding Reference Signal (SRS). For other terminal behaviors during the SCG period, some behaviors will be restricted to save terminal power consumption, and other behaviors may continue to be executed to speed up SCG activation to start data transmission as soon as possible.

[0004] However, there are at least two scenarios:

[0005] Scenario 1: When the terminal has triggered random access, the network sends an SCG deactivation command to the terminal at the same time;

[0006] Scenario 2: In the SCG deactivated state, when the terminal requests to activate the SCG, it can initiate random access on the SCG. If the terminal has already initiated random access on the SCG, and at the same time the network side sends the terminal configuration information for triggering a new random access.

[0007] The above two scenarios may cause the terminal to perform unnecessary random access, resulting in unnecessary power consumption of the terminal, or the terminal may perform unnecessary SCG deactivation operations, which does not meet the current requirements of the terminal for the SCG state. Summary of the invention

[0037] The following, in conjunction with the accompanying drawings, describes in detail the random access processing method, device and terminal provided in the embodiments of the present application through some embodiments and their application scenarios.

[0038] like Figure 2 As shown, an embodiment of the present application provides a random access processing method, including:

[0039] Step 101, during the process of performing a first random access on the secondary cell group SCG by the terminal, if a first condition is met, the terminal performs a first operation; wherein the first condition includes at least one of the following: the terminal initiates a second random access; the terminal receives first configuration information; the terminal receives the SCG deactivation command; the first configuration information is used to trigger bandwidth part BWP switching and / or third random access;

[0040] The first operation is one of the following:

[0041] Continue to perform the first random access;

[0042] Stop performing the first random access.

[0043] In an embodiment of the present application, when the first condition is met, whether the terminal continues to perform the first random access or stops performing the first random access may be determined by the network configuration or by a pre-set condition; wherein the relevant conditions may be set by the network or agreed upon by a protocol or pre-determined by the terminal and the network, and are not specifically limited here.

[0044] It should be noted that when the terminal performs the first random access on the SCG, the SCG can be in an activated state or a deactivated state, which is not specifically limited here. For example, the SCG is in an activated state, and the terminal initiates the first random access on the primary or secondary cell PSCell or the SCG secondary cell; for another example, the SCG is in a deactivated state, uplink data arrives at the SCG, and the terminal requests to activate the SCG, then the terminal initiates the first random access on the PSCell.

[0045] In at least one embodiment of the present application, when the first condition is that the terminal initiates the second random access,

[0046] At least one of the first random access and the second random access is triggered by the terminal when the SCG is in a deactivated state.

[0047] For example, if the first random access is triggered by the terminal when the SCG is in an activated state, the second random access may be triggered by the terminal when the SCG is in an activated state, or may be triggered by the terminal when the SCG is in a deactivated state; for another example, if the first random access is triggered by the terminal when the SCG is in a deactivated state, the second random access is also triggered by the terminal when the SCG is in a deactivated state.

[0048] As an optional embodiment of the present application, in step 201, during the process in which the terminal performs the first random access on the secondary cell group SCG, if the terminal initiates the second random access, the terminal stops performing the first random access, including:

[0049] If the second random access is triggered by executing CPC (Conditional PSCell Change), when the second condition is met, the terminal stops performing the first random access; optionally, after the terminal stops performing the first random access, the terminal may continue to perform the second random access.

[0050] The second condition includes at least one of the following:

[0051] The first random access is triggered by uplink data arriving at the SCG when the terminal is in a deactivated state;

[0052] The first random access is triggered by the terminal when uplink data reaches the SCG and the SCG is out of uplink synchronization when the SCG is in a deactivated state;

[0053] The first random access is triggered by the terminal when uplink data arrives at the SCG and the terminal has no uplink resources for sending a scheduling request SR when the SCG is in a deactivated state;

[0054] The first random access is triggered by beam failure recovery BFR.

[0055] In one embodiment, when the SCG is in a deactivated state, the terminal initiates a first random access request on the SCG to activate the SCG due to uplink data reaching the SCG. During this process, the terminal continues to evaluate and execute conditional PSCell changes, thereby triggering a second random access when the CPC execution condition is met. Since the execution of CPC causes the terminal to switch to a new target PSCell, there is no need for the terminal to initiate a random access on the original source PSCell, so the terminal stops the first random access and initiates a second random access.

[0056] As at least one optional embodiment of the present application, during the process of the terminal performing the first random access on the secondary cell group SCG in step 201, if the terminal receives the SCG deactivation command, the terminal performs the first operation, including:

[0057] When a third condition is met, the terminal performs the first operation; wherein the third condition includes at least one of the following:

[0058] The first random access is triggered by uplink data arriving at the SCG and the SCG uplink of the terminal being out of synchronization;

[0059] The first random access is triggered by uplink data arriving at the SCG and the terminal having no uplink resources for sending an SR;

[0060] The first random access is triggered by a terminal requesting activation of the SCG;

[0061] The first random access is triggered by SR failure of the SCG;

[0062] The first random access is triggered by BFR;

[0063] The first random access is triggered by executing CPC;

[0064] The first random access is triggered by establishing a TA (Time Alignment) of a secondary Timing Advance Group (sTAG).

[0065] It should be noted that, during the process of the terminal performing the first random access on the secondary cell group SCG, if the terminal receives the SCG deactivation command, at least the following is included:

[0066] The SCG is in an activated state, and during the process of the terminal performing a first random access on the SCG, the terminal receives an SCG deactivation command;

[0067] The SCG is in a deactivated state. During the first random access of the terminal on the SCG, the terminal receives an SCG deactivation command; for example, the terminal undergoes a handover without PSCell change, and the target master node decides to keep the SCG in a deactivated state. The target master node then sends an SCG deactivation command to the terminal.

[0068] As an optional embodiment, when the third condition includes at least one of the following, the terminal continues to perform the first random access:

[0069] The first random access is triggered by a terminal requesting activation of the SCG;

[0070] The first random access is triggered by SR failure of the SCG;

[0071] The first random access is triggered by uplink data arriving at the SCG and the SCG uplink of the terminal being out of synchronization;

[0072] The first random access is triggered by uplink data arriving at the SCG but the terminal has no uplink resources for sending an SR.

[0073] As another optional embodiment, when the third condition includes at least one of the following, the terminal stops performing the first random access:

[0074] The first random access is triggered by BFR;

[0075] The first random access is triggered by executing CPC;

[0076] The first random access is triggered by a TA that establishes an sTAG.

[0077] As another optional embodiment, if the third condition is triggered when the SCG is in an activated state, the terminal continues to perform the first random access; if the third condition is triggered when the SCG is in a deactivated state, the terminal stops performing the first random access.

[0078] For example, when SCG is in the activated state, the terminal has uplink data to be sent. In the absence of physical uplink control channel PUCCH / physical uplink shared channel PUSCH resources, the terminal needs to initiate random access to apply for uplink transmission resources. During this process, the network side may send an SCG deactivation command to the terminal due to tight network resources. Therefore, the terminal can stop initiating random access to avoid the network side needing to send the SCG deactivation command again after initiating random access.

[0079] For example, when the SCG is in the deactivated state, the terminal initiates random access on the SCG because uplink data arrives at the SCG. During this process, the terminal is switched. Since the target primary base station and the secondary base station do not know whether the terminal has uplink data to send at this time, the target primary base station may send an SCG deactivation command to the terminal to keep the SCG in the deactivated state. Therefore, the terminal can continue to initiate random access, thereby notifying the network side of the uplink data to be transmitted by the terminal.

[0080] For another example, if CPC execution is triggered when SCG is in an activated state, the terminal will initiate a random access, which may be initiated on the dedicated random access resources configured by the target PSCell for the UE. If the terminal receives an SCG deactivation command during the random access, the terminal should prioritize completing the first random access, and then optionally deactivate the SCG, or not deactivate the SCG and wait for the target PSCell to decide whether to deactivate the SCG.

[0081] For another example, if CPC is triggered when SCG is in a deactivated state, and the terminal initiates random access, the random access may be a contention random access, that is, not initiated on a dedicated random access resource. Then the terminal may not initiate random access first, and wait until SCG is activated before initiating random access.

[0082] In at least one optional embodiment of the present application, when the first condition is that the terminal receives an SCG deactivation command,

[0083] If the first operation is to continue the first random access, the method further includes:

[0084] The terminal ignores the SCG deactivation command, or the terminal deactivates the SCG after the first random access is completed;

[0085] Alternatively, if the first operation is to stop performing the first random access, the method further includes:

[0086] The terminal deactivates the SCG according to the SCG deactivation command.

[0087] As at least one optional embodiment of the present application, in the process of the terminal performing the first random access on the secondary cell group SCG in step 201, if the terminal receives the first configuration information, the terminal stops performing the first random access, including:

[0088] When a fourth condition is met, the terminal stops performing the first random access;

[0089] The fourth condition includes at least one of the following:

[0090] The first configuration information includes a dedicated random access resource;

[0091] The first configuration information triggers a primary and secondary cell change (PSCell change);

[0092] The first configuration information triggers SCG activation.

[0093] The terminal receiving the first configuration information includes:

[0094] The terminal receives the first configuration information when the SCG is in a deactivated state.

[0095] As an optional embodiment of the present application, during the process of the terminal performing the first random access on the secondary cell group SCG, if the terminal receives the first configuration information, after the terminal stops performing the first random access, the method further includes at least one of the following:

[0096] The terminal performs BWP switching according to the first configuration information;

[0097] Initiating, by the terminal, a third random access according to the first configuration information;

[0098] The terminal performs BWP switching according to the first configuration information, and initiates random access on the switched BWP.

[0099] As another optional embodiment of the present application, during the process in which the terminal performs the first random access on the secondary cell group SCG, if the terminal receives the first configuration information, after the terminal continues to perform the first random access, the method further includes:

[0100] not performing the BWP switching; or,

[0101] The BWP switching is performed after the first random access is completed.

[0102] In an embodiment of the present application, during the process of the terminal performing the first random access on the secondary cell group SCG, if the first condition is met, the terminal continues to perform the first random access or stops performing the first random access; this can avoid the terminal performing unnecessary random access, thereby increasing terminal power consumption and SCG activation delay; or avoid the terminal performing unnecessary SCG deactivation, thereby meeting the terminal's own SCG activation / deactivation requirements.

[0103] In order to more clearly describe the random access processing method provided in the embodiment of the present application, several examples are provided below for illustration.

[0104] Example 1: During SCG activation, the terminal has an ongoing first random access on the SCG and receives an SCG deactivation command

[0105] Step s1, the SCG is in an activated state, and the terminal initiates a first random access on the PSCell or the SCell of the SCG;

[0106] Step s2: When the first random access process is in progress, the terminal receives an SCG deactivation command and performs one of the following operations:

[0107] A1: Continue the ongoing first random access. Optionally, ignore the SCG deactivation command. Optionally, perform the operation when the following conditions are met, including:

[0108] The first random access is triggered by a terminal requesting activation of the SCG;

[0109] The first random access is triggered by SR failure of the SCG;

[0110] The first random access is triggered by uplink data arriving at the SCG and the SCG uplink of the terminal being out of synchronization;

[0111] The first random access is triggered by uplink data arriving at the SCG and the terminal having no uplink resources for sending an SR;

[0112] B1, stop the ongoing first random access; optionally, perform the operation when the following conditions are met, the conditions including:

[0116] Example 2: During SCG deactivation, the terminal has an ongoing first random access on the SCG and receives first configuration information, which triggers BWP switching and / or new random access (third random access)

[0117] Step s1, the SCG is in a deactivated state, and the terminal initiates a first random access on the PSCell. For example, uplink data arrives at the SCG, and the terminal requests to activate the SCG;

[0118] Step s2: While the first random access process is in progress, the terminal receives first configuration information sent by the network side, and the first configuration information triggers the BWP switching of the PSCell or a new random access (for example, downlink data arrives at the SCG, the network side activates the SCG, and configures the terminal with RACH resources and / or a suitable BWP), and the terminal performs one of the following operations:

[0119] A2: Stop the ongoing first random access. Further, perform BWP switching or initiate a new random access according to the first configuration information. Optionally, after performing BWP switching, initiate a random access on the switched BWP; Optionally, stop the ongoing first random access only when at least one of the following conditions is met:

[0120] The first configuration information includes a dedicated RACH resource;

[0121] The first configuration information triggers a PSCell change;

[0122] B2, continue the ongoing first random access; optionally, do not perform BWP switching, or perform BWP switching after the random access is completed.

[0123] Example 3: During SCG deactivation, the terminal receives an SCG deactivation command when there is an ongoing first random access on the SCG

[0124] Step s1, the SCG is in a deactivated state, and the terminal initiates a first random access on the PSCell. For example, uplink data arrives at the SCG, and the terminal requests to activate the SCG;

[0125] Step s2: When the first random access process is in progress, the terminal receives an SCG deactivation command (for example, the terminal switches without changing the PSCell, and the target master node decides to keep the SCG in a deactivated state), and the terminal performs one of the following operations:

[0126] A3, stop the ongoing first random access. Further, execute the SCG deactivation command to deactivate the SCG;

[0127] B3, continue the ongoing first random access; optionally, the terminal ignores the SCG deactivation command, or the terminal deactivates the SCG after the first random access is completed.
