Embodiment Construction

[0025] figure 1 A schematic structural diagram of a downlink subframe according to an embodiment of the present invention is shown. Such as figure 1 As shown, the downlink domain and the uplink domain are configured in the downlink subframe, wherein the uplink domain is located at the end of the downlink subframe. And, a guard interval is configured between the downlink domain and the uplink domain.

[0026] Here, the uplink field is located at the end of the downlink subframe. Embedding the uplink field into the downlink subframe can reduce the time of the handshake process between the UE and the eNB. The handshake process may be, for example, data transmission initiated by the UE, a HARQ process, random access, and the like. In addition, placing the uplink domain at the edge of the downlink subframe can reduce the number of transitions in each downlink subframe to one, which will save half the power consumption.

Abstract

The invention provides methods for configuring an uplink sub-frame and a downlink sub-frame. According to one embodiment of the invention, a method for configuring the downlink sub-frame is provided; and the method comprises the following steps of: configuring a downlink domain and an uplink domain in the downlink sub-frame, wherein the uplink domain is positioned at the tail end of the downlink sub-frame; and configuring a guard interval between the downlink domain and the uplink domain. According to the other embodiment of the invention, a method for configuring the uplink sub-frame is provided; and the method comprises the following steps of: configuring a downlink domain and an uplink domain in the uplink sub-frame, wherein the downlink domain is positioned at the starting end of the uplink sub-frame; and configuring a guard interval between the downlink domain and the uplink domain.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for configuring uplink subframes and downlink subframes. Background technique [0002] The 5G physical layer is dedicated to providing high-performance data rates with reduced cost and power consumption [1]. As mentioned in the literature [2], a large number of MIMO, high frequency band and dense arrangement of small cells will be the main technology to meet the high performance requirements of 5G. In addition, system scalability, flexibility to maintain uplink and downlink capabilities, and optimized use of unpaired spectrum are also very important for the 5G concept. In addition, in addition to traditional UE-eNB access, more and more various new links are beginning to appear, such as self-backhaul links for inter-eNB communication and device-to-device links that do not require infrastructure. [0003] Based on this requirement of 5G, considering the low cost and h...
