Definitions
- the present invention relates to the field of communications, and in particular, to an asynchronous uplink method, a terminal, and a base station.
- terminal and network synchronization are mainly two processes, one is frame synchronization, one is time synchronization, frame synchronization refers to downlink synchronization, and time synchronization refers to uplink synchronization, for example, in LTE (Long Time Evolution, long-term In the evolution, when the uplink signals of different UEs (User Equipments) arrive at the eNB (evolved Node B), time alignment is required to reduce the interference of uplink signals between UEs, if the UE is far away during the call. When the direction of the base station moves, the signal sent from the base station will arrive at the UE "later and later".
- LTE Long Time Evolution, long-term In the evolution
- UEs User Equipments
- eNB evolved Node B
- the signal of the UE will arrive at the base station "later and later", and the delay will be too long, which will result in the base station receiving.
- the signal of the UE on the time slot and the time slot of the base station receiving another UE signal overlap each other, causing inter-symbol interference.
- the time alignment of the uplink transmission is implemented by applying TA (Timing Advance) on the UE side, and the TA can let the UE send signals in advance.
- TA Timing Advance
- establishing a communication connection between a UE and an eNB includes a contention based random access procedure and a non-contention based random access procedure.
- the step of the contention-based random access procedure is: in the first step, the UE randomly selects a preamble, and sends a preamble to the eNB on an available PRACH (Physical Random Access Channel) resource; After receiving the preamble, the eNB sends a random access response (RAR) message to the UE, where the message carries the uplink grant information and the UE uplink timing advance information.
- PRACH Physical Random Access Channel
- the third step is The UE sends an uplink message to the eNB according to the uplink grant and the timing advance information in the RAR, where the uplink message includes the content that can identify the UE.
- the eNB sends a contention resolution message to the UE, and the UE determines the random according to the contention resolution message. Whether the access process was successfully completed.
- the non-contention-based random access procedure is: the first step, that is, the eNB configures a dedicated preamble for the UE, and optionally includes a PRACH resource that transmits the preamble; and in the second step, the UE sends the available PRACH resource.
- a dedicated preamble is sent to the eNB.
- the eNB After receiving the preamble, the eNB sends a random access response message (RAR) to the UE, where the message carries the uplink grant information, and the UE uplink timing advance information; the UE receives the corresponding After the random access response message, it is considered that the random access process is successfully completed and then executed. Subsequent data transceiving process.
- RAR random access response message
- Step 1 After the uplink data arrives, the UE will trigger a BSR (Buffer Status Report) when a certain condition is met. If no uplink resource is sent to the BSR, the SR (Scheduling) is triggered. Request, scheduling request, the SR indicates that the UE has uplink data triggering the BSR and needs to be sent; Step 2: After receiving the SR, the eNB can only determine that the UE has uplink data to be sent, but does not know any other data cached by the UE.
- BSR Buffer Status Report
- the information is allocated to the uplink resource according to the scheduling algorithm, and the UL Grant (Up Load Grant) notification is sent to the UE for the uplink resource allocated by the UE.
- Step 3 After the UE receives the UL Grant, the UE allocates the uplink resource.
- the BSR is sent to the eNB to inform the eNB of the current amount of uplink data buffered.
- Step 4 After receiving the BSR, the eNB knows the uplink data volume of the UE more accurately, and allocates appropriate uplink resources to the UE according to the scheduling algorithm.
- the UE sends a UL Grant (uplink authorization) notification to the uplink resource allocated to it; Step 5: After receiving the UL Grant, the UE performs uplink data on the uplink resource allocated for the UE. Lose. However, some UEs do not have dedicated SR resources. If the UE does not have dedicated SR resources, or the UE is in an out-of-synchronization state, it needs to use the random access procedure to request uplink data transmission resources. When the UE has uplink data transmission, Need to request resources or establish RRC connection and data bearer first, which greatly increases signaling overhead and delay.
