Embodiment 1

[0060] For UEs with dynamic uplink and downlink configuration adjustment functions, the base station configures a dedicated RNTI (Radio Network Temporary Identifier, Radio Network Temporary Identifier) ​​through high-level signaling, which is recorded as TDD-RNTI. The configured TDD-RNTI is the same as the existing All RNTIs configured to the UE are different:

[0061] In this embodiment, the downlink control information format containing the same number of bits as the existing downlink control information format 1A or 1C is used to carry the uplink and downlink configuration information, which is called downlink control information format 1E in this embodiment, as shown in figure 2 As shown, the information bits contained in the downlink control information format sent by the base station are used to indicate the uplink and downlink configuration information; considering that there are 7 kinds of uplink and downlink configurations supported by the existing TDD system, therefo...

Embodiment 2

[0068] On the basis of Embodiment 1, if the base station configures the same dynamic uplink and downlink configuration adjustment dedicated RNTI and the same TDD-index for multiple UEs, the uplink and downlink configurations of the multiple UEs are the same. Group UEs are configured with the same uplink and downlink configuration.

Embodiment 3

[0070] On the basis of Embodiment 2, if there are multiple UE groups, you can configure the same dynamic uplink and downlink configuration adjustment dedicated RNTI for these UE groups, but for different UE groups, configure different TDD-index, you can Realize carrying the uplink and downlink configuration information of multiple groups of UEs in one downlink control information format, which can greatly reduce the The overhead of the physical downlink control channel.

Abstract

A method for notifying uplink / downlink configuration information. The method comprises: a base station delivering a downlink control information format to a user equipment (UE), uplink / downlink configuration information used for indicating an uplink / downlink configuration being carried.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a notification and acquisition method of uplink and downlink configuration information, a base station and user equipment. Background technique [0002] Time Division Duplex (TDD, Time Division Duplex) system divides uplink (sent by the terminal to the base station) and downlink (sent by the base station to the terminal) resources in the time domain, and usually allocates uplink and downlink resources in units of time slots or subframes . Generally, the base station notifies all terminals in the cell of the allocation of uplink and downlink resources by using broadcast signaling in a semi-static manner. [0003] For example, figure 1 The frame structure of the TDD mode of the Long Term Evolution (LTE, Long Term Evolution) system (also known as the second type of frame structure, namely frame structure type2) is given. In this frame structure, a wireless frame of 10 millisec...
