Embodiment Construction

[0039]In the embodiment of the present invention, the network-side device sends TDD uplink and downlink configuration information through determined physical resources, and high-version user equipment that can support dynamic changes in TDD uplink and downlink configuration information receives TDD uplink and downlink configuration information through determined physical resources, wherein the physical resources are not related to Other channels and signals collide. Since the TDD uplink and downlink configuration information is transmitted through certain physical resources, the physical resources do not collide with other channels and signals other than PDSCH, thus supporting flexible transmission of uplink and downlink subframe configuration information, ensuring the uplink and downlink subframe configuration information and The normal transmission of other channel signals avoids the transmission performance degradation or incorrect transmission caused by the conflict between...

Abstract

The embodiment of the invention relates to the technical field of wireless communication and specifically relates to a method, system and device for sending and receiving configuration information so that transmission of uplink and downlink subframe configuration information can be supported. The method for sending the configuration information includes: a network-side device determines physical resources which need to carry TDD uplink and downlink configuration information, wherein the physical resources do not collide with other channels or signals excluding a PDSCH; and the network-side device sends the TDD uplink and downlink configuration information through the determined physical resources. Because the TDD uplink and downlink configuration information is transmitted through the determined physical resources, wherein the physical resources do not collide with other channels or signals excluding the PDSCH, normal transmission of the uplink and downlink subframe configuration information and the signals of the other channels is ensured and degeneration of transmission performance or incapability of normal transmission caused by the collision of the physical resources with the other channels and signals is prevented.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for sending and receiving configuration information. Background technique [0002] As one of the two basic duplex systems, the TDD (Time division duplex, time division duplex) mode has received more and more attention under the background of the increasing demand for bandwidth in broadband mobile communications. In a TDD system, uplink and downlink transmission use the same frequency resource, and uplink / downlink signals are transmitted on different time slots. Common TDD systems include 3G TD-SCDMA (Time Division Synchronized Code Division Multiple Access, Time Division Synchronous CDMA; CDMA, Code Division Multiple Access, Code Division Multiple Access) system and 4G TD-LTE (TD-SCDMA Long Term Evolution, Time Division Synchronous Code Division Multiple Access - Long Term Evolution) system, the division of uplink and downlin...
