Embodiment Construction

[0038] In one embodiment of the present disclosure, a unified subframe structure suitable for TDD is proposed for uplink and downlink, so as to meet the requirements of the 5G concept. According to an embodiment of the present disclosure, based on the subframe configuration, each subframe includes one or more of the following: a downlink control field, a downlink data field, an uplink control field, and an uplink data field. In addition, multiple subframe configurations are set, which respectively correspond to subframes with different domains and / or domain lengths, so that subframes / subframe configurations can adapt to different uplink / downlink ratios, for example. This adaptation method is more flexible than that in the prior art by distinguishing uplink / downlink subframes to achieve a desired uplink / downlink ratio.

[0039] In addition, a subframe configuration and its valid time, and / or a subframe pattern composed of at least one subframe configuration and its valid time m...

Abstract

The embodiments of the invention provide a method and a device for configuring a sub-frame. In one embodiment of the invention, the method comprises the following steps: configuring a sub-frame to serve as a sub-frame for uplink transmission and a sub-frame for downlink transmission; and configuring the sub-frame according to at least one of a downlink control domain, a downlink data domain, an uplink control domain and an uplink data domain. Through a unified sub-frame structure and the method for configuring a sub-frame presented by the embodiments of the invention, original frame configuration can be simplified, and the signaling overhead can be reduced. In addition, dynamic sub-frame configuration based on instantaneous service adaptation is more flexible.

Description

technical field [0001] Embodiments of the present disclosure relate to communication technologies, and in particular to a method and device for configuring 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 user equipment-base station (UE-eNB) access, more and more new links are emerging, 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...
