27、e the LWAAP architecture and the LWAAP entities from a functional point of view. 4.2 LWAAP architecture 4.2.1 LWAAP entities The description in this sub clause is a model and does not specify or restrict implementations. RRC is generally in control of the LWAAP configuration. Functions of the LWAAP

28、sublayer are performed by LWAAP entities. For an LWAAP entity configured at the eNB, there is a peer LWAAP entity configured at the UE and vice versa. For all LWA bearers, there is one LWAAP entity in the eNB and one LWAAP entity in the UE. An LWAAP entity receives/delivers LWAAP SDUs from/to upper

29、layers (i.e. PDCP) and sends/receives LWAAP PDUs to/from its peer LWAAP entity via WLAN: - At the eNB, when an LWAAP entity receives an LWAAP SDU from upper layers, it constructs the corresponding LWAAP PDU and delivers it to lower layers; - At the UE, when an LWAAP entity receives an LWAAP PDU from

30、 lower layers, it reassembles the corresponding LWAAP SDU and delivers it to upper layers. Figure 4.2.1-1 illustrates the overview model of the LWAAP sublayer.

31、 entity delivers/receives the following LWAAP PDU to/from a lower layer entity: - LWAAP data PDU. 4.3 Services 4.3.1 Services provided to upper layers The following services are provided by LWAAP to upper layers (i.e. PDCP): - transfer of user plane data; 4.3.2 Services expected from lower layers Th

32、e following services are expected by LWAAP from lower layers: - transfer of user plane data; 4.4 Functions The following functions are supported by the LWAAP sublayer: - transfer of user plane data; - identification of the LWA bearer to which the LWAAP SDU belongs. 5 Procedures 5.1 Data transfer pro

33、cedures 5.1.1 DL data transfer procedures When receiving an LWAAP data PDU from lower layers, the LWAAP entity in the UE shall: - identify the upper layer entity to which the LWAAP SDU is destined based on the DRB ID included in the LWAAP header; - reassemble the LWAAP SDU from the LWAAP data PDU by

34、 removing the LWAAP header from the LWAAP data PDU; - deliver the reassembled LWAAP SDU to the upper layer entity identified by the DRB ID. 5.2 Handling of unknown, unforeseen and erroneous protocol data When an LWAAP entity receives an LWAAP PDU that contains reserved or invalid values, the LWAAP e

35、ntity shall: - discard the received PDU. ETSI ETSI TS 136 360 V13.0.0 (2016-04)83GPP TS 36.360 version 13.0.0 Release 136 Protocol data units, formats and parameters 6.1 Protocol data units 6.1.1 General An LWAAP PDU is a bit string that is byte aligned (i.e. multiple of 8 bits) in length. In the fi

36、gures in subclause 6.1, bit strings are represented by tables in which the most significant bit is the leftmost bit of the first line of the table, the least significant bit is the rightmost bit on the last line of the table, and more generally the bit string is to be read from left to right and the

37、n in the reading order of the lines. The bit order of each parameter field within an LWAAP PDU is represented with the first and most significant bit in the leftmost bit and the last and least significant bit in the rightmost bit. An LWAAP SDU is a bit string that is byte aligned (i.e. multiple of 8

38、 bits) in length. An LWAAP SDU is included into an LWAAP PDU from the first bit onward. The LWAAP entity shall ignore the value of Reserved bits in downlink LWAAP PDUs. Only one type of LWAAP PDU is defined, i.e. LWAAP data PDU. 6.1.2 LWAAP data PDU An LWAAP PDU consists of an LWAAP header and a Dat

39、a field, as described in Figure 6.1.2-1. An LWAAP header is one byte, and consists of the four header fields R/R/R/DRBID. A Data field is of variable size, and consists of an LWAAP SDU. Figure 6.1.2-1: LWAAP data PDU 6.2 Formats and parameters 6.2.1 LWAAP header The LWAAP header consists of the foll

40、owing fields: - R: Reserved bit, set to “0“. The R field size is 1 bit; - DRBID: The Data Radio Bearer ID field indicates the RRC configured DRB identity to which the corresponding LWAAP SDU belongs. The DRBID field size is 5 bits.
