RRC is gener
41、ally in control of the RLC configuration. ETSI ETSI TS 136 322 V13.1.0 (2016-04)83GPP TS 36.322 version 13.1.0 Release 13Functions of the RLC sub layer are performed by RLC entities. For a RLC entity configured at the eNB, there is a peer RLC entity configured at the UE and vice versa. For an RLC en
42、tity configured at the transmitting UE for STCH or SBCCH there is a peer RLC entity configured at each receiving UE for STCH or SBCCH. An RLC entity receives/delivers RLC SDUs from/to upper layer and sends/receives RLC PDUs to/from its peer RLC entity via lower layers. An RLC PDU can either be a RLC
43、 data PDU (see sub clause 6.1.1) or a RLC control PDU (see sub clause 6.1.2). If an RLC entity receives RLC SDUs from upper layer, it receives them through a single SAP between RLC and upper layer, and after forming RLC data PDUs from the received RLC SDUs, the RLC entity delivers the RLC data PDUs
44、to lower layer through a single logical channel. If an RLC entity receives RLC data PDUs from lower layer, it receives them through a single logical channel, and after forming RLC SDUs from the received RLC data PDUs, the RLC entity delivers the RLC SDUs to upper layer through a single SAP between R
45、LC and upper layer. If an RLC entity delivers/receives RLC control PDUs to/from lower layer, it delivers/receives them through the same logical channel it delivers/receives the RLC data PDUs through. An RLC entity can be configured to perform data transfer in one of the following three modes: Transp
46、arent Mode (TM), Unacknowledged Mode (UM) or Acknowledged Mode (AM). Consequently, an RLC entity is categorized as a TM RLC entity, an UM RLC entity or an AM RLC entity depending on the mode of data transfer that the RLC entity is configured to provide. A TM RLC entity is configured either as a tran
47、smitting TM RLC entity or a receiving TM RLC entity. The transmitting TM RLC entity receives RLC SDUs from upper layer and sends RLC PDUs to its peer receiving TM RLC entity via lower layers. The receiving TM RLC entity delivers RLC SDUs to upper layer and receives RLC PDUs from its peer transmittin
48、g TM RLC entity via lower layers. An UM RLC entity is configured either as a transmitting UM RLC entity or a receiving UM RLC entity. The transmitting UM RLC entity receives RLC SDUs from upper layer and sends RLC PDUs to its peer receiving UM RLC entity via lower layers. The receiving UM RLC entity
49、 delivers RLC SDUs to upper layer and receives RLC PDUs from its peer transmitting UM RLC entity via lower layers. An AM RLC entity consists of a transmitting side and a receiving side. The transmitting side of an AM RLC entity receives RLC SDUs from upper layer and sends RLC PDUs to its peer AM RLC entity via lower layers. The receiving side of an AM RLC entity delivers RLC SDUs to upper layer and receives RLC PDUs from its peer AM RLC entity via lower layers.
