Description

Resource request method in dual connectivity mode and terminal, primary base station and secondary base station

【技术领域】[Technical Field]

The present invention relates to the field of communications, and in particular, to a resource request method in a dual connectivity mode, and a terminal, a primary base station, and a secondary base station.

【背景技术】【Background technique】

In the existing wireless network transmission, the low frequency band carrier coverage is large, but the resources are scarce. The high-band carrier coverage is small, but the resources are relatively rich. In the traditional 2G and 3G networks, carriers in the lower frequency band are generally used to provide services for users. However, with the popularity of smartphones, users have placed higher demands on wireless transmission rates. In order to meet the needs of users, it is necessary to gradually use resource-rich high-band carriers to provide services.

Due to the small coverage of the high-band carrier, the base station that uses the high-band carrier to perform a certain small coverage becomes a small base station, and the coverage range is called a small cell. It should be noted that, in general, the macro base station will be selected as the primary base station (Macro). Evolved Node B, MeNB), and selects the small base station as a secondary base station (Small evolved Node B, SeNB). There may be multiple cells in the MeNB, and one of the multiple cells may be selected as a primary cell (PCell) and a terminal (User). Equipment, UE) provides services, while other cells can be secondary cells (Secondary Cell, SCell), providing services for the UE. The secondary cell of the primary base station and the cell under the SeNB are generally selected as the secondary cell, that is, the SCell provides services for the UE. Generally, the main difference between the primary cell and the secondary cell is that the primary cell establishes RRC for the initial connection or handover of the UE (Radio). Resource Control, radio resource control) The connected cell provides the UE with security and mobility management related parameters, and also serves to transmit UE user plane data, while the secondary cell is mainly responsible for transmitting user plane data for the UE.

When the UE works under the dual connectivity of the MeNB and the SeNB, the MeNB and the SeNB respectively configure an independent physical uplink control channel (Physical Uplink). Control Channel, PUCCH) is used for uplink scheduling request and feedback of uplink control information, such as channel state information (Channel State) Information, CSI), hybrid automatic repeat request response (Hybrid Automatic Repeat Request- Acknowledgement, HARQ-ACK) feedback of information, etc. Scheduling request under normal circumstances The Request, SR) can be reported separately using the respective PUCCH channel resources.

In the existing long-term evolution (Long Term In the evolution, LTE) system, when the transmission resource of the SR is not configured, the UE may trigger random access in the PCell (the PCell is located in the MeNB, which is a serving cell of the MeNB) (Random). Access, RA) procedure to request uplink grant (UL grant); or, when the SR reaches the maximum number of transmissions, the UE may initiate an RA procedure at the PCell to request UL Grant. However, when the UE does not configure the SR, if the RA process that initiates the contention on the SCell requests to schedule the resource, the UE needs to perform a common search space for the SCell of the SeNB (Common Search Space, CSS) blind detection, which will increase the number of blind detections and false alarms of the UE. If the SR reaches the preset maximum number of times, if the RA process that initiates the contention on the SCell requests to schedule resources, it continues to initiate RA at the SeNB. The meaning is small, because at this time, the MeNB may have been replaced due to signal quality reasons.

Specifically, the terminal 10 first establishes a communication connection with the primary base station 11 for normal data transmission, and then the primary base station 11 adds the secondary base station 12 to the terminal 10, and the terminal 10 establishes a communication connection with the secondary base station 12 for normal data transmission. The terminal 10 can simultaneously communicate with the primary base station 11 and the secondary base station 12, that is, establish a communication system of the dual connectivity mode. The communication connection between the terminal 10, the primary base station 11 and the secondary base station 12 is a wireless connection, and the primary base station 11 and the secondary base station 12 respectively allocate independent physical uplink control channels for the terminal.

After the scheduling request or hybrid automatic repeat request response and/or channel state information of the terminal 10 on the secondary base station 12 side is triggered, the terminal 10 determines the resource condition of the first message configured by the secondary base station 12. The first message is used to request resources from the secondary base station 12 or to feed back information received in the downlink. When the secondary base station 12 is configured not to allocate the resource for transmitting the first message or the number of times the first message is sent to the preset maximum value, the secondary base station 12 is not configured to be used when the scheduling request of the secondary base station 12 is triggered. Sending the resource of the scheduling request, or scheduling the number of times the request is sent on the configured resource reaches a preset maximum value; or when the hybrid automatic repeat request response and/or channel state information of the secondary base station 12 side is triggered, the secondary base station 12 does not have Effective physical uplink control channel resources and/or physical uplink shared channels (Physical Uplink Share The Channel, PUSCH) resource may be used to feed back the hybrid automatic repeat request response and/or channel state information, or to feed back the hybrid automatic repeat request response and/or the channel state information to a preset threshold.

If the secondary base station 12 is not configured to send the resource of the first message or the number of times the first message is sent on the configured resource reaches a preset maximum value, the terminal 10 sends a second message to the primary base station 11 for scheduling. The second message is used to report that the secondary base station 12 is not configured to send the first message or the number of times the first message is sent on the configured resource reaches a preset maximum value. The secondary base station 12 is configured not to configure the resource for sending the first message or the maximum number of times the first message is sent on the configured resource reaches the preset maximum value.

1) When the scheduling request on the secondary base station 12 side is triggered, and the secondary base station 12 is not configured with the resource for transmitting the scheduling request, the terminal 10 reports the scheduling request message to the primary base station 11 on the physical uplink control channel of the primary base station 11, that is, the first The second base station 11 sends the scheduling indication information to the secondary base station 12 to notify the secondary base station 12 that the terminal 10 needs to request uplink granting at the secondary base station 12 or the secondary cell, and after receiving the uplink granting scheduling request, the secondary base station 12 sends the scheduling request to the terminal. 10 assigns an uplink grant. The scheduling request message may be a physical layer signaling or a control element of media access control (Medium) Access Control Control Element (MAC CE) or Radio Resource Control (Radio Resource) A control, RRC) message is used to indicate that the terminal 10 needs to request an uplink grant at the secondary base station 12.

The message, the second message. After receiving the second message, the primary base station 11 sends different indication information to the secondary base station 12 according to resource conditions such as the signal strength of the secondary base station 12 or the secondary cell. Specifically, if the resource strength of the secondary base station 12 or the secondary cell is poor, the primary base station 11 sends the secondary base station/secondary cell removal indication information to the secondary base station 12, indicating that the secondary base station 12 or the secondary cell stops providing the terminal 10 The primary base station 11 also sends the secondary base station/secondary cell replacement indication information or the secondary base station/secondary cell removal indication information to the terminal 10, wherein the secondary base station/secondary cell replacement indication information includes the notification that the secondary base station 12 is replaced or deactivated. Information of the secondary cell and information of the newly added or activated secondary base station/secondary cell. The secondary base station/secondary cell removal indication information includes information of the removed secondary base station/secondary cell. If the resource strength of the secondary base station 12 or the secondary cell is better, the primary base station 11 sends scheduling indication information to the secondary base station 12 to notify the secondary base station 12 that the terminal 10 needs to request uplink granting at the secondary base station 12 or the secondary cell. After receiving the scheduling request of the uplink grant, the uplink grant is assigned to the terminal 10.

In this embodiment, when the secondary base station 12 is not configured to send the first message or the number of transmissions reaches a preset maximum value, the terminal 10 sends a second message to the primary base station 11, and the primary base station 11 sends The indication information is sent to the secondary base station 12 to indicate that the secondary base station 12 stops providing services to the terminal 10 or allocates resources to the terminal 10, instead of allowing the terminal 10 to directly communicate with the secondary base station 12. The second message is used for reporting that the secondary base station 12 is not configured to transmit the first. The resource or the number of times the message is sent reaches a preset maximum value. The first message is used to request resources from the secondary base station 12 or to feed back the downlink received information, thereby preventing the terminal 10 from performing a random access procedure at the secondary base station 12, thereby reducing the terminal 10 The number of blind checks and false alarm efficiency.

S31: Receive indication information sent by the primary base station 11, where the indication information is sent according to the second message sent by the terminal 10, and the second message is used to report that the secondary base station 12 is not configured to send the first message or the configured resource. The number of times the first message is sent reaches a preset maximum value. The first message is used to request resources from the secondary base station 12 or feed back information received by the terminal.

In S31, the terminal 10 first determines the resource condition of the first message configured by the secondary base station 12. If the secondary base station 12 is not configured to send the resource of the first message or the number of times the first message is sent on the configured resource reaches a preset maximum value, the indication information sent by the primary base station 11 is received. The indication information is sent according to the second message sent by the terminal 10. The second message sent by the terminal 10 is that the secondary base station 12 reported by the terminal 10 is not configured to send the first message or the first message on the configured resource. The number of transmissions reaches the preset maximum. In an embodiment of the present invention, the second message is scheduling request information, and may be one physical layer signaling, for example, signaling sent on an uplink PUCCH channel, and one MAC. The CE or RRC message is used to indicate that the terminal 10 needs to request the uplink grant at the secondary base station 12. Preferably, the second message is an extended buffer status report message, and the extended buffer status report message includes the terminal needs to send to the secondary base station 12.

The second message may also be an enhanced scheduling request message, including at least one of the first information and the second information, where the first information indicates that the scheduling request is performed by the secondary base station 12, and the second information indicates that the first message is at the secondary base station. 12 The number of transmissions reaches the preset maximum value.

When the secondary base station 12 is configured not to allocate the resource for transmitting the first message or the number of times the first message is sent to the preset maximum value, the secondary base station 12 is not configured to be used when the scheduling request of the secondary base station 12 is triggered. Sending the resource of the scheduling request, or scheduling the number of times the request is sent on the configured resource reaches a preset maximum value; or when the hybrid automatic repeat request response and/or channel state information of the secondary base station 12 side is triggered, the secondary base station 12 does not have Valid physical uplink control channel resources and/or physical uplink shared channel resources may be used to feed back hybrid automatic repeat request acknowledgement and/or channel state information, or feedback hybrid automatic repeat request acknowledgement and/or channel state information failures may reach a pre-fetch Set the threshold.

Therefore, in the embodiment of the present invention, the resources for sending the first message are not configured for the secondary base station 12, or the number of transmissions reaches a preset maximum value, which can be separately described in the following three application scenarios:

1) When the scheduling request of the secondary base station 12 is triggered, the secondary base station 12 is not configured with the resource for transmitting the scheduling request, and the indication information sent by the primary base station 11 is scheduling indication information, to instruct the secondary base station 12 to allocate the uplink grant to the terminal 10. .

2) When the scheduling request on the side of the secondary base station 12 is triggered, the number of times the scheduling request is sent on the configured resource reaches a preset maximum value, and the receiving primary base station 11 transmits the resource according to the signal strength of the secondary base station 12 or the secondary cell. Different instructions. Specifically, if the resource strength of the secondary base station 12 or the secondary cell is poor, the secondary base station/secondary cell removal indication information sent by the primary base station 11 is received, that is, the indication information is removal indication information, to indicate the secondary base station 12. Or the secondary cell stops providing services to the terminal 10. The secondary base station/secondary cell removal indication information includes information of the removed secondary base station/secondary cell. If the resource strength of the secondary base station 12 or the secondary cell is better, the scheduling indication information sent by the primary base station 11 is received, that is, the indication information is scheduling indication information, to notify the secondary base station 12 that the terminal 10 requests the secondary base station 12 or the SCell. Upgrading.

3) When the hybrid automatic repeat request response and/or channel state information on the secondary base station 12 side is triggered, the secondary base station 12 has no valid physical uplink control channel resources and/or physical uplink shared channel resources available for feedback hybrid automatic repeat request. When the response and/or channel state information, or the number of failures of the feedback hybrid automatic repeat request response and/or channel state information reaches a preset threshold, the hybrid automatic repeat request response sent by the primary base station 11 is received and/or The channel state information feedback resource allocation indication information, that is, the indication information is a hybrid automatic repeat request response and/or channel state information feedback resource allocation indication information, to instruct the secondary base station 12 to allocate the terminal 10 for the hybrid automatic repeat request response and/or Or physical uplink control channel resources and/or physical uplink shared channel resources fed back by channel state information.

S32: Allocate resources to the terminal 10 according to the indication information or stop serving the terminal 10.

Specifically, when the scheduling request on the secondary base station 12 side is triggered, and the secondary base station 12 does not configure the resource for transmitting the scheduling request, the uplink grant is allocated to the terminal 10 according to the scheduling indication information sent by the primary base station 11. When the scheduling request of the secondary base station 12 is triggered, the number of times the scheduling request is sent on the configured resource reaches a preset maximum value, and if the indication information is the secondary base station/secondary cell removal indication information, the service is stopped from being provided to the terminal. If the indication information is scheduling indication information, the uplink grant is assigned to the terminal. When the secondary base station 12 does not have valid physical uplink control channel resources and/or physical uplink shared channel resources, it can be used to feed back hybrid automatic repeat request response and/or channel state information, or feed back hybrid automatic repeat request response and/or channel state information. When the number of failures reaches the preset threshold, the terminal allocates a new hybrid automatic repeat request response to the terminal according to the hybrid automatic repeat request response and/or the resource allocation indication information of the channel state information sent by the primary base station 11. And/or resource information of channel state information.

In the prior art, in the dual connectivity mode, if the terminal 10 and the secondary base station 12 directly communicate, it is necessary to perform a random access procedure at the secondary base station 12, that is, to monitor the common search space of the secondary base station 12, which inevitably leads to additional In the present embodiment, when the secondary base station 12 is configured not to configure the resource for transmitting the first message or the number of transmissions reaches a preset maximum value, the indication information sent by the primary base station 11 is received, and the indication information is based on the terminal. 10, sent by the second message, further stopping the service of the terminal 10 or allocating resources to the terminal 10 according to the indication information, instead of allowing the terminal 10 to directly communicate with the secondary base station 12, and the second message is used for reporting that the secondary base station 12 is not configured. The first message is used to request resources from the secondary base station 12 or to feed back downlink received information, which prevents the terminal 10 from performing a random access procedure at the secondary base station 12, thereby reducing the number of the first message. The number of blind detections and false alarm efficiency of the terminal 10.

In 4b, the terminal 20 transmits scheduling request information to the primary base station 21. In 5b, the primary base station 21 transmits the secondary base station/secondary cell removal indication information to the secondary base station 22. Thus, the primary base station 21 instructs the secondary base station 22 to stop providing services to the terminal 20. In 6b, the primary base station 21 transmits the secondary base station/secondary cell replacement indication information to the terminal 20. The secondary base station/secondary cell replacement indication information includes information that informs the secondary base station 22 that the secondary base station 22 is replaced or deactivated, and information of the newly added or activated secondary base station/secondary cell. In other embodiments of the present invention, the primary base station 21 may also transmit the secondary base station/secondary cell removal indication information to the terminal 20.
