Embodiment 1
[0102] Embodiment 1: subframe-level synchronization control, such as figure 1 shown, including:
[0103] Step 101, the base station combines channel estimation results of all uplink channels configured in each uplink time slot in the same subframe of the same user equipment (UE), respectively, to obtain joint channel estimation results for each uplink time slot of the UE;
[0104] The joint channel estimation of each uplink time slot can be calculated according to the following formula:
[0105] h pow , j ts = | Σ mid = 0 MidNum - 1 h mid , j | 2 ...
Embodiment 2
[0139] Embodiment 2: time slot level synchronization control, such as figure 2 shown.
[0140] This embodiment is mainly aimed at the following situation: there is no situation that the same type of uplink channel of the same user is located in multiple uplink time slots in the same subframe, that is, the same type of uplink channel is located in one uplink time slot.
[0141] Step 201, the base station combines the channel estimation results of all uplink channels configured in one uplink time slot in one subframe of the same UE, to obtain the joint channel estimation result of the UE in this time slot;
[0142] The joint channel estimation can be calculated according to formula (1) or formula (2).
[0143] Step 202, the base station calculates the unified synchronization timing advance of the current time slot of the UE according to the joint channel estimation result obtained in step 201;
[0144] When calculating the unified synchronization timing advance of the UE, the...
Embodiment 3
[0164] Embodiment 3: time slot level synchronization control, such as image 3 shown.
[0165] This embodiment mainly addresses the following situation: the same type of uplink channel of the same user is located in multiple uplink time slots in the same subframe, that is, the same type of uplink channel is located in multiple uplink time slots.
[0166] Step 301, the base station combines channel estimation results of all uplink channels configured in each uplink time slot of the same UE respectively, to obtain a joint channel estimation result of each time slot of the UE;
[0167] The joint channel estimation can be calculated according to formula (1) or formula (2).
[0168] Step 302, the base station calculates the unified synchronization timing advance of each time slot of the UE according to the joint channel estimation results in each time slot obtained in step 301;
[0169] Step 303, the base station adjusts the unified synchronization timing advance; the base statio...
