Description

Information transmission method and equipment
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to an information transmission method and apparatus.
Background
An End-Marker (End identifier) control PDU (Protocol Data Unit), which is a Service Data Attachment Protocol (SDAP) entity at a terminal side and is sent to an SDAP entity at a network side, and is used to instruct to stop mapping from QoS flow (Quality of Service flow) to Data Radio Bearer (DRB). The length of the data transmission protocol is one byte, and the data transmission protocol carries a D/C (quality of service) field and QFI (QoS Flow ID, quality of service Flow identifier), wherein the D/C field is used for indicating whether the PDU is a control PDU or a data PDU.
Referring to fig. 1, a flow of an existing terminal (UE) transmitting an End-Marker control PDU to a network side device (e.g., a gNB). According to the definition of the current PDCP (Packet Data Convergence Protocol) Protocol sublayer, the PDCP can only process Data packets in two modes, namely AM (acknowledged mode) RLC (Radio Link Control) and UM (unacknowledged mode) RLC, i.e., an End-Marker Control PDU sent from the SDAP Protocol sublayer is processed by the PDCP Protocol sublayer and then a PDCP PDU header of 2-3 bytes and a MAC-I (message authentication code) of 4 bytes are added. After the PDCP PDU carrying the End-Marker control PDU is processed by the RLC protocol sublayer, an RLC header with 1-3 bytes is added. After the RLC PDU carrying the End-Marker Control PDU is processed by a MAC (Media Access Control) protocol sublayer, the length of a MAC sub-header of 2 bytes is also increased. It is calculated that in order to transmit an End-Marker control PDU with a length of one byte, various overhead of 9 to 12 bytes are added. This is obviously an inefficient, high load transmission.

step 11: the SDAP layer sends the End-Marker control PDU to the MAC layer in one of the following modes:
the End-Marker control PDU is directly sent to the RLC layer through a data interface between the SDAP layer and the RLC layer, and the RLC layer sends the PDU to the MAC layer;
the End-Marker control PDU is sent to a PDCP layer, and the PDCP layer directly sends the control PDU to the MAC layer through a data interface between the PDCP layer and the MAC layer;
directly sending the End-Marker control PDU to the MAC layer through a data interface between the SDAP layer and the MAC layer;

and sending the End-Marker control PDU to a PDCP layer, transmitting the control PDU to an RLC layer by the PDCP layer, and transmitting the control PDU to the MAC layer by the RLC layer.
In the embodiment of the invention, when the SDAP layer of the communication equipment at the sending End sends the End-Marker control PDU to the communication equipment at the receiving End, the SDAP layer directly sends the End-Marker control PDU to the MAC layer without passing through the PDCP layer and/or the RLC layer per se, or sends the End-Marker control PDU to the MAC layer through the transparent transmission mode of the PDCP layer and/or the RLC layer per se, thereby, the packet heads of the PDCP layer and/or the RLC layer are not required to be increased, the head overhead when the End-Marker control PDU is transmitted is reduced, the load is also reduced, and the transmission speed is also improved. In addition, the transmission method of the End-Marker control PDU for reducing the load and improving the transmission speed is simple and easy to realize.
The communication device may be a terminal, or may be a network side device (e.g., a base station).
The above-described information transmission method is exemplified below.
In this embodiment of the present invention, optionally, after the step of sending the End-Marker control PDU to the MAC layer, the method further includes:
the MAC layer constructs the End-Marker Control PDU into a corresponding MAC CE (Control Element, control unit or Control Element), and adds the Control Element to the MAC PDU to be sent to a lower layer.
In the embodiment of the invention, a new MAC CE is introduced into the MAC layer, namely the MAC CE used for reporting the End-Marker control PDU of the SDAP layer is added into the MAC layer. The id for the newly added MAC CE can be determined in the following two ways:
1. the ID of the MAC CE of the End-Marker control PDU of the SDAP layer is newly defined, for example, as MAC _ CE ID, and a fixed value is determined for the MAC _ CE ID.
2. According to the existing protocol, a special LCID (Logical Channel identity) is used for identification. Specifically, an available value of the LCID value specified by the existing protocol may be selected to identify the MAC CE of the End-Marker control PDU of the SDAP layer.
For the id information of the MAC CE, there may be the following two transmission modes:
1. the MAC PDU which sends the MAC CE is directly carried, namely the MAC PDU also comprises the identity type identification information of the MAC CE; or,
2. the identity type identifier information of the MAC CE is carried by an RRC signaling, so that the identity type identifier information is configured to each protocol sublayer (an MAC layer, a PDCP layer, an RLC layer, and the like) of the communication device layer 2 and/or each protocol sublayer of the receiving-end communication device layer 2, that is, the identity type identifier of the MAC CE may be configured to a relevant protocol sublayer of a terminal and/or a network-side device through the signaling.
And the identity type identification information is used for indicating that the MAC CE carries the End-Marker control PDU.
Optionally, the step of sending the End-Marker control PDU to the MAC layer includes:
sending the End-Marker control PDU to the MAC layer together with information related to the End-Marker control PDU, the information related to the End-Marker control PDU including at least one of:
type indication information for indicating the End-Marker control PDU as a control PDU;
the End-Marker controls the length information of the PDU;
and the End-Marker controls the QoS requirement information of the PDU.
That is, when the SDAP layer of the communication device at the sending End directly sends the End-Marker control PDU to the MAC layer, or sends the End-Marker control PDU to the MAC layer through the PDCP layer and/or the transparent transmission mode of the RLC, some information related to the End-Marker control PDU can be carried.
Further optionally, the QoS requirement information of the End-Marker control PDU includes at least one of:
sending delay of an air interface;
maximum number of retransmissions;
and the receiving end feeds back the latest moment of confirmation after successfully receiving.
In this embodiment of the present invention, the information related to the End-Marker control PDU may also be some other information, which is not described in detail herein.
Optionally, the MAC CE includes one or more End-Marker control PDUs.
In the embodiment of the present invention, the content of the MAC CE of the End-Marker control PDU, which indicates that the communication device (sending End, for example, a terminal) reports to the SDAP layer of the communication device (base station) at the receiving End is newly defined, and specifically there may be two types:
1. the new MAC CE is defined using the means specified by the existing protocol. The MAC header format uses the format already specified in the protocol, and the contents of the MAC CE are shown in fig. 4 (Oct: byte, SDU: service Data Unit) when there is only one End-Marker control PDU in the MAC CE, and fig. 5 when there are two or more End-Marker control PDUs in the MAC CE.
2. When the ID type ID of the MAC CE is newly defined as MAC _ CE ID, the ID type ID (MAC _ CE ID) is put together with the End-Marker control PDU. The MAC header still uses the existing definition. For example, when the length of the MAC _ CE ID is defined as one byte, the contents of the MAC CE having only one End-Marker control PDU are as shown in fig. 6, and the contents of the MAC CE having more than one End-Marker control PDU are as shown in fig. 7.

step 21: the MAC layer receives data sent by a lower layer;
step 22: and the MAC layer analyzes the End-Marker control PDU from the data sent by the lower layer and sends the PDU to the SDAP layer.
In the embodiment of the invention, when the SDAP layer of the communication equipment at the sending End sends the End-Marker control PDU to the communication equipment at the receiving End, the End-Marker control PDU is directly sent to the MAC layer without passing through the PDCP layer and/or the RLC layer of the communication equipment, or the End-Marker control PDU is sent to the MAC layer through the transparent transmission mode of the PDCP layer and/or the RLC layer of the communication equipment. Therefore, the MAC layer of the receiving-End communication equipment can directly send the End-Marker control PDU upwards to the SDAP layer after analyzing the End-Marker control PDU from the data sent by the lower layer, thereby improving the transmission efficiency and reducing the data processing capacity.
The communication device may be a network side device (e.g., a base station) or a terminal.
Optionally, the data sent by the lower layer is a MAC PDU;
the MAC layer analyzes the End-Marker control PDU from the data sent by the lower layer and sends the End-Marker control PDU to the SDAP layer, and the method comprises the following steps:

Further optionally, the step of parsing, by the MAC layer, the End-Marker control PDU from the MAC CE and sending the End-Marker control PDU to the SDAP layer includes:
if only one End-Marker control PDU exists in the MAC CE, the MAC CE is sent to the SDAP layer;
