Description

Uplink transmission process number indication method and related equipment

technical field

The present invention relates to the technical field of wireless communication, and in particular, to an uplink transmission process number indication method and related equipment.

Background technique

Mobile data traffic will explode in the near future. It is estimated that the global mobile data traffic will increase by more than 200 times from 2010 to 2020, and will increase by nearly 20,000 times from 2010 to 2030. In the future, the total number of devices connected to the global mobile communication network will reach a scale of 100 billion. It is estimated that by 2020, the number of global mobile terminals (excluding IoT devices) will exceed 10 billion, of which China will exceed 2 billion. The number of global IoT device connections will also grow rapidly to 2030, and the global IoT device connection number will be close to 100 billion, of which China will exceed 20 billion.

Currently, in the LTE (Long Term Evolution, Long Term Evolution) system, uplink and downlink data scheduling is performed through PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) or E-PDCCH (Enhanced Physical Downlink Control Channel, Enhanced Physical Downlink Control Channel) To achieve one-to-one scheduling between eNB (Evolved Node B, evolved base station) and UE (User Equiment, user equipment), that is, each UE can receive uplink scheduling instructions for the UE from eNB through PDCCH or E-PDCCH. The ultra-high number of user connections in future communications and the potential number of concurrent access users pose a challenge to the capacity of the control channel. In the future LTE evolution system, the optimization of control channel overhead will become an important direction. The scheduling-free uplink contention transmission scheme is an optimization direction. In this solution, the eNB configures the same contention resource for a group of UEs and does not send an uplink scheduling instruction for a single UE, and the UE's uplink data transmission is initiated by itself.

In this scheduling-free uplink contention transmission scheme, when different UEs compete for transmission on the same contention resource, a conflict may occur, resulting in transmission failure. If the synchronous retransmission scheme is adopted for retransmission (the time of retransmission is kept at a fixed time interval from the time of initial transmission), then the UEs that collide during the initial transmission will send at the same time during the retransmission, resulting in the accumulation of conflicts. Therefore, the scheduling-free uplink contention transmission needs to adopt an asynchronous retransmission scheme, wherein the asynchronous retransmission means that there is no fixed time interval between the initial transmission and the retransmission. Specifically, when synchronous retransmission is enabled (a fixed time interval k is used between the initial transmission and the retransmission), then the retransmission at a certain time n is the initial transmission initiated at a certain time n-k, and the difference between the retransmission and the initial transmission The connection can be determined by the timing relationship, but in the case of asynchronous retransmission, the connection cannot be established directly, and the retransmission at time n may also be initiated by the initial transmission at other times.

If the application scenario has high requirements for transmission delay, then multiple HARQ (HybridAutomatic Repeat reQuest, hybrid automatic repeat request) processes need to be enabled to ensure that when multiple data packets arrive at the same time, they can be transmitted in parallel (on the contrary Ground, multiple data packets can only initiate the transmission of the next data packet after the transmission of one data packet is completed). The concept of the HARQ process is that if there is only a single HARQ process, before a packet completes the transmission task (including the initial transmission, retransmission until the final transmission is completed), the next packet cannot initiate transmission, and multiple HARQ processes are equivalent to multiple parallel If there is a single HARQ process, then before a packet transmission task is completed, other packets can also initiate transmission, but this does not mean that the retransmission of the packet sent later will be later than the packet sent earlier, such as the process ID is received at time n. If the initial transmission packet is 1, and the initial transmission packet with process number 2 is received at n+1, the retransmission packet received at n+5 may be process number 2, and the retransmission is received at n+6. The package may be process number 1. Therefore, there is the concept of a HARQ process, and the associated initial transmission packet and the retransmission packet are associated by the HARQ process number.

If multiple HARQ processes for uplink transmission are enabled, the UE must enable the eNB to obtain the process ID used for this transmission during each transmission, otherwise the eNB cannot associate the initial transmission packet with the retransmission packet in the same HARQ process and Get the HARQ combining gain. Since the eNB cannot indicate the HARQ process number to the UE under the scheduling-free uplink contention transmission scheme, how the UE transmits the HARQ process number to the eNB is an urgent problem to be solved.
