In this embodiment, based on the flexible air interface flow control capability of the MAC layer, the network side and the terminal side can complete flexible selection of an air interface link through the MAC peer-to-peer protocol layer regardless of whether the terminal has the multi-connection capability. When the terminal only has single connection capability, the MAC layer can keep that the terminal only has one air interface link which can interact with the network side on the time domain; when the terminal has a multi-link capability, the MAC layer may keep the terminal having one or more air interface links in the time domain, which may interact with the network side.
In the Random Access (RA), the MAC layer has flexible air interface flow control capability, and can realize a multi-air interface channel Access scheme of the terminal so as to improve the robustness of the RA process.
This embodiment explains a procedure for initiating random access by a network side:

and selecting a target MAC from the at least one real-time MAC based on the channel measurement information, and performing random access interactive processing with the user equipment based on an air interface channel corresponding to the target MAC.
That is, when a network side initiates a random access process for a terminal, the FC-MAC is quickly controlled to select an air interface channel most suitable for the UE (the air interface channel quality of the UE meets a certain requirement, and the RA load on the physical channel meets the requirement) to initiate an RA process;
in the subsequent RA process step (the RA process is composed of a plurality of steps), the network side dynamically selects the best air interface channel of the terminal according to the channel measurement information reported by the terminal, and the information interaction of the subsequent RA step is completed.
The air interface channel selected when the network device first initiates the random access RA procedure may be an air interface channel corresponding to a real-time RT-MAC selected according to a history of the user equipment (terminal); or, an air interface channel may be randomly selected, which is not exhaustive in this embodiment.
In addition, in the subsequent random access interaction processing, one or more MACs selected and obtained by receiving the channel measurement information sent by the user equipment can be used as the target RT-MAC for interaction.
It should be further noted that, referring to fig. 2, the structure of the MAC based on this embodiment first receives a random access request sent by a User Equipment (UE) through a physical layer (PHY); and then the air interface channel of the physical layer sends the random access request sent by the physical layer to a fast control FC-MAC in the MAC layer for processing based on the corresponding real-time RT-MAC, wherein the FC-MAC also carries out processing such as identification information interaction with a radio link control (RRC) layer.

and selecting a target MAC from the at least one real-time MAC, and sending a response message corresponding to the context information to the user equipment based on an air interface channel corresponding to the target MAC.
The FC-MAC on the network side may select the target MAC and the corresponding air interface channel thereof to complete the subsequent RA procedure step according to the received channel information and measurement information of the terminal.
Referring to fig. 2, in a random access procedure initiated by a UE, after an RT-MAC submits RA information of a terminal to an FC-MAC, the FC-MAC applies to an RRC to establish context signaling of the UE. And after receiving the FC-MAC application, the RRC of the network side configures the context information of the UE. And the RRC at the terminal side inquires the stored configuration context, if the configuration context exists, the configuration context is sent to the RT-MAC appointed by the FC-MAC, and otherwise, the configuration context initiates an application to the RRC at the network side.

receiving a temporary identification aiming at the user equipment sent by an RRC layer;
and sending the temporary identifier of the user equipment to the selected at least one real-time MAC, and sending response information containing the temporary identifier to the user equipment through the at least one real-time MAC.

Therefore, the flexible control capability of the MAC at the air interface can be fully utilized, the problem that the user equipment is accessed only through the dominant frequency in the prior art is solved, and the user equipment can be interacted through one or more air interface channels, so that the flexibility and the robustness of the random access process are improved.
Example four,
An embodiment of the present invention provides a user equipment, as shown in fig. 6, including:
a processing unit 61, configured to receive at least one real-time MAC allocated by a network side; each real-time MAC in the at least one real-time MAC corresponds to one air interface channel;
the communication unit 62 is configured to perform random access interaction processing with the network side through an air interface channel corresponding to at least part of the at least one real-time MAC.
Here, the network device may be a base station, an eNB, or other devices; the user equipment may be a device capable of accessing a mobile communication network, and may be a mobile phone, for example.
In this embodiment, based on the flexible air interface flow control capability of the MAC layer, the network side and the terminal side can complete flexible selection of an air interface link through the MAC peer-to-peer protocol layer regardless of whether the terminal has the multi-connection capability. When the terminal only has single connection capability, the MAC layer can keep that the terminal only has one air interface link which can interact with the network side on the time domain; when the terminal has a multi-link capability, the MAC layer may keep the terminal having one or more air interface links in the time domain, which may interact with the network side.
In the Random Access (RA), the MAC layer has flexible air interface flow control capability, and can realize a multi-air interface channel Access scheme of the terminal so as to improve the robustness of the RA process.
This embodiment explains a procedure for initiating random access by a network side:
receiving channel measurement information sent by user equipment;
and selecting a target MAC from the at least one real-time MAC based on the channel measurement information, and performing random access interactive processing with the user equipment based on an air interface channel corresponding to the target MAC.
That is, when a network side initiates a random access process for a terminal, the FC-MAC is quickly controlled to select an air interface channel most suitable for the UE (the air interface channel quality of the UE meets a certain requirement, and the RA load on the physical channel meets the requirement) to initiate an RA process;
in the subsequent RA process step (the RA process is composed of a plurality of steps), the network side dynamically selects the best air interface channel of the terminal according to the channel measurement information reported by the terminal, and the information interaction of the subsequent RA step is completed.
The air interface channel selected when the network device first initiates the random access RA procedure may be an air interface channel corresponding to a real-time RT-MAC selected according to a history of the user equipment (terminal); or, an air interface channel may be randomly selected, which is not exhaustive in this embodiment.
In addition, in the subsequent random access interaction processing, one or more MACs selected and obtained by receiving the channel measurement information sent by the user equipment can be used as the target RT-MAC for interaction.
It should be further noted that, referring to fig. 2, the structure of the MAC based on this embodiment first receives a random access request sent by a User Equipment (UE) through a physical layer (PHY); and then the air interface channel of the physical layer sends the random access request sent by the physical layer to a fast control FC-MAC in the MAC layer for processing based on the corresponding real-time RT-MAC, wherein the FC-MAC also carries out processing such as identification information interaction with a radio link control (RRC) layer.
This embodiment explains a procedure for initiating random access by a user equipment side:
the communication unit is used for sending a random access preamble to a network side through an initial air interface channel corresponding to the initial real-time MAC;
and the real-time MAC corresponding to the initial air interface channel is the same as or different from at least one real-time MAC sent by a network side.
When the terminal side initiates the random access process, the FC-MAC of the terminal side may select any air interface channel to initiate the RA process.
The communication unit is configured to receive the random access response message sent by the network device through at least part of the at least one real-time MAC;
and selecting a target MAC from the at least one real-time MAC, sending a context message to the network equipment through an air interface channel corresponding to the target MAC, and receiving a response message corresponding to the context message sent by the network equipment through the air interface channel corresponding to the target MAC.
The FC-MAC on the network side may select the target MAC and the corresponding air interface channel thereof to complete the subsequent RA procedure step according to the received channel information and measurement information of the terminal.
Referring to fig. 2, in a random access procedure initiated by a UE, after an RT-MAC submits RA information of a terminal to an FC-MAC, the FC-MAC applies to an RRC to establish context signaling of the UE. And after receiving the FC-MAC application, the RRC of the network side configures the context information of the UE. And the RRC at the terminal side inquires the stored configuration context, if the configuration context exists, the configuration context is sent to the RT-MAC appointed by the FC-MAC, and otherwise, the configuration context initiates an application to the RRC at the network side.
After receiving the random access preamble, the quick control MAC sends identification request information of the user equipment to a radio link control (RRC) layer;
receiving a temporary identification aiming at the user equipment sent by an RRC layer;
and sending the temporary identifier of the user equipment to the selected at least one real-time MAC, and sending response information containing the temporary identifier to the user equipment through the at least one real-time MAC.
Specifically, referring to fig. 3, the terminal initiates an RA procedure, where CCx/y/z represents different air interface channels. The method comprises the following steps:
and Step 1a, the UE sends RA Preamble resources to the network according to the configuration in the system broadcast.
And Step 1b, after receiving the Preamble, the PHY layer of the base station sends the Preamble to the RT-MAC, and the RT-MAC and the FC-MAC complete internal interaction and select the available RT-MAC for the UE.
And Step 1C, after receiving the Preamble, the FC-MAC layer of the base station applies for the identity of the UE (such as TC-RNTI: Temporary C-RNTI) from the RRC layer.
And Step 2a, the RRC allocates corresponding TC-RNTI according to the use condition of the RATI and directly sends the TC-RNTI to RT-MAC appointed by the FC-MAC, wherein the RT-MAC is selected by the FC-MAC and can not be different from RT-MAC of an air interface channel initiated by the UE initially.
RT-MAC constructs RA Response message, which contains RA-RTNI used by UE, and the selection of RA-RNTI can be defined according to future communication system, or can follow the existing mode of LTE system.
Phy sends data to the air interface in the air interface channel, Step 2c.
And Step 3a, selecting a proper air interface channel by the UE according to the air interface channel receiving the RA Response message to send the context establishment request message. The air interface channel at this time may be any one of all channels available to the UE.
And Step 3 b-3 c, the RT-MAC/FC-MAC/RRC at the network side completes the processing of the context establishment request message sent by the UE and generates a corresponding response message.
And Step 4a, the RRC sends the response message to the RT-MAC appointed by the FC-MAC for processing and sending.
And Step 4c, finishing the sending of the response message on the appointed air interface channel.
Therefore, by adopting the scheme, at least one real-time MAC can be allocated to the user equipment in the random access processing process, and then access interaction is carried out with the user equipment through an air interface channel corresponding to at least part of the MAC in the at least one real-time MAC. Therefore, the flexible control capability of the MAC at the air interface can be fully utilized, the problem that the user equipment is accessed only through the dominant frequency in the prior art is solved, and the user equipment can be interacted through one or more air interface channels, so that the flexibility and the robustness of the random access process are improved.
