Embodiment 1
[0023] Embodiment 1: Satellite air interface resource allocation and recovery process based on shared resource pool
[0024] The allocation of the satellite wireless air interface shared resource pool is closely combined with the satellite air interface communication process, such as figure 1 As shown, this embodiment provides the communication process between the satellite terminal and the radio resource controller as well as the channel allocation and recovery process, and the specific steps are as follows:
[0025] (1) The radio resource controller first performs radio resource pool planning, and plans a common channel resource pool and a dedicated channel resource pool for each beam;
[0026] (2) The radio resource controller establishes a broadcast channel, a random access channel, and an access authorization channel in each beam according to the resource planning in the common channel resource pool; wherein, the broadcast channel is a unidirectional downlink channel, and...
Embodiment 2
[0033] Embodiment 2: Channel resource pool division and resource block cutting method based on shared resource pool
[0034] (1) Firstly, the satellite air interface wireless resources are divided into public channel resource pools and dedicated channel resource pools.
[0035] (2) Five resource blocks are planned in the common channel resource pool, resource block 1 is used for broadcast channel, resource block 2 and resource block 3 are used for random access channel, resource block 4 and resource block 5 are used for accessing authorized channel. All 5 channels are established and used at one time when the beam is established.
[0036] (3) Resources in the dedicated channel resource pool are allocated dynamically according to the communication process of the satellite terminal. Resource block 1 is used for the signaling channel of satellite terminal A, resource block 2 is used for the traffic channel of satellite terminal A, resource block 3 is used for the signaling chann...
