Embodiment Construction
[0024] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 with figure 2 As shown, the present invention provides a full-duplex relay data packet optimal scheduling method of a 5G front-end equipment, the method first time slot t , the number of data packets in the cache of the 5G front-end equipment H and to t user until slot i for packets j reception of to initialize, let t =0; H =0; , n represents the number of users, K Indicates the number of data packets to be sent; then perform the following steps:
[0026] (1) The macro base station performs random linear encoding on the data to be sent, generates an encoded data packet, and sends it to the 5G front-end equipment; t = t +1; go to step (2);
[0027] (2) Determine whether the 5G front-end equipment has received the data packet sent by the macro base station; if so, H = H +1, go to step (4); ...

The invention discloses a full duplex relay data packet optimization scheduling method for 5G front-end equipment, and the method comprises the steps that a macro base station firstly carries out therandom linear network coding of a to-be-transmitted data packet, wherein each coded data packet is a random linear combination about all original data packets; then the coded packets are sent to the 5G front-end equipment in sequence; the 5G front-end equipment works in a full duplex mode, puts the received data packets into a cache region, and broadcasts one packet selected from its own cache toall users; the users decode the original data block; and when all the users decode the original data blocks, transmission is completed. According to the invention, the data packet optimization scheduling technology is applied to the 5G front-end equipment, and the relay base station performs data packet optimization scheduling according to the success rate of receiving the data packet by the user,the current channel state of each user, the receiving condition of the data packet by the user and other information, so that the transmission efficiency is obviously improved.
Description
technical field [0001] The invention belongs to the technical field of wireless network communication, and in particular relates to a method for optimizing and scheduling full-duplex relay data packets of 5G front-end equipment. Background technique [0002] In a 5G heterogeneous network, some front-end equipment can be deployed to enhance the signal coverage in specific areas (such as underground garages and large building shelters). These devices include small base stations, femtocells, relay base stations, etc. [0003] The 5G front-end equipment is between the macro base station and the user, so it acts as a data relay. Relays can be divided into half-duplex relays and full-duplex relays. Half-duplex data transmission means that data can be transmitted in two directions of a signal carrier, but cannot be transmitted at the same time, and the throughput is relatively low. But full-duplex communication allows data to be transmitted in both directions simultaneously, the...
