Embodiment 1

[0088] Embodiment 1 Re-establishing the secondary RLC entity after deactivating packet repetition

[0089] If packet repetition is configured and is in the deactivated state (or receives an indication from upper or lower layers to deactivate packet repetition), for the purpose of MAC buffer status reporting (buffer status reporting), the PDCP data volume of the PDCP sending entity may include: (1) PDCP SDUs that have not yet constructed PDCP data PDUs; (2) PDCP data PDUs that have not yet been delivered to the primary RLC entity; (3) PDCP control PDUs (or PDCP control PDUs that have not yet been delivered to the primary RLC entity); (4) for AM DRB, the PDCP SDU to be retransmitted described in PDCP entity re-establishment (PDCP entity re-establishment, 3GPP TS38.323); (5) For AM DRB, the PDCP to be retransmitted described in data recovery (data recovery, 3GPP TS38.323) Data PDUs.

[0090] Optionally, the PDCP sending entity deletes the PDCP PDU delivered to the primary RLC en...

Embodiment 2

[0092] Example 2: The secondary RLC entity is not rebuilt after deactivation and packet repetition

[0093] If packet repetition is configured and is in the deactivated state (or an indication of deactivated packet repetition is received from upper or lower layers), for the purpose of MAC buffer status reporting, the PDCP data volume of the PDCP sending entity may include: (1) also PDCP SDUs that have not constructed PDCP data PDUs; (2) PDCP data PDUs that have not been delivered to the lower layer (or PDCP data PDUs that have not been delivered to the primary RLC entity); (3) PDCP control PDUs (or PDCP control PDUs that have not been delivered to the lower layer or that have not yet been delivered) PDCP control PDU of the main RLC entity); (4) For AM DRB, PDCP entity re-establishment (PDCP entity re-establishment, 3GPP TS38.323) describes the PDCP SDU to be retransmitted; (5) For AM DRB, data recovery ( data recovery, 3GPP TS38.323) describes the PDCP data PDU to be retransmi...

Embodiment 3

[0111] Embodiment 3 After deactivating packet repetition, only the primary RLC entity is used and the secondary RLC entity is not rebuilt

[0112] If packet repetition is configured and is in the deactivated state (or an indication of deactivated packet repetition is received from the upper layer or lower layer), if the data separation threshold is configured, further, if the PDCP data volume of the PDCP sending entity is associated with the PDCP entity The sum of the amount of RLC data used for initial transmission in the primary RLC entity is less than the data separation threshold (or, if the sum of the amount of PDCP data of the PDCP sending entity and the amount of RLC data used for initial transmission in the two RLC entities associated with the PDCP entity is less than Data separation threshold), the PDCP sending entity submits the PDCP PDU to the main RLC entity.

[0113] For the purpose of determining whether to use link selection (or for determining whether to use tw...

Abstract

The invention provides user equipment and a related method. The method is a method performed by user equipment (UE), and a packet data convergence protocol (PDCP) sending entity is configured with a packet repetition, and associated with two radio link control (RLC) entities, the method comprises: receiving a packet repetition activation / deactivation media access control (MAC) control element CE;and the PDCP sending entity deletes the PDCP protocol data unit (PDU) which has been submitted to any associated RLC entity. According to the method, the data size needing to be transmitted can be reduced, so that communication resources can be saved, and the communication efficiency and the communication speed are improved.

Description

technical field [0001] The present disclosure relates to the field of wireless communication technologies, and more specifically, the present disclosure relates to user equipment and related operations in a state where packet repetition is deactivated and a method for calculating data volume. Background technique [0002] In March 2016, at the 3rd Generation Partnership Project (3rd Generation Partnership Project: 3GPP) RAN#71 plenary meeting, NTT DOCOMO proposed a new research project on 5G technical standards (see non-patent literature: RP-160671 : New SID Proposal: Study on New Radio Access Technology), and was approved. The purpose of this research project is to develop a new radio (New Radio: NR) access technology to meet all application scenarios, requirements and deployment environments of 5G. NR has three main application scenarios: enhanced mobile broadband communication (Enhanced mobilebroadband: eMBB), large-scale machine type communication (massive Machine type ...
