Abstract

Provided are a user equipment (UE) and a communication method and device over an unlicensed spectrum in a base station. In order to solve the problem of restricted configuration of a TDD frame structure over the unlicensed spectrum due to the size of interface management traffic adaptation (eIMTA) signaling, the solution of the present invention allows a given frame having a set of applicable TDD frame structures configured in eIMTA signaling to cover a plurality of frequency bands scheduled in the given frame by the target UE. For each subframe, the solution of the present invention allows a dynamically configured maximum number of TDD frame structures supported by the eIMTA to change from the configured carrier number to the actually scheduled carrier number, being better adapted to DFS technology. As one embodiment, a reconstruction index in the logical information corresponding to a virtual index in the scheduling DCI indicates which set of TDD frame structures in the eIMTA signaling are the TDD frame structures adopted by the scheduling DCI. In addition, when possible, the present invention reuses the CA and eIMTA programs in the existing LTE, thus having better compatibility.

Description

Communication method and device on unlicensed spectrum in UE and base station

Technical field

The present invention relates to a scheme for utilizing unlicensed spectrum communication in a wireless communication system, and more particularly to a communication method and apparatus for unlicensed spectrum based on LTE (Long Term Evolution).

Background technique

The 3GPP (3rd Generation Partner Project) R (Release, version) 12 introduces eIMTA (enhanced interference management traffic adaptation) technology, that is, for TDD (Time Division Duplex, The time-division duplex structure can adjust the TDD frame structure through dynamic signaling. The possible TDD frame structure includes 7 TDD frame structures of #0 to 6 defined in LTE. The 3GPP RAN (Radio Access Network) #76 meeting further clarified that dynamic signaling (eIMTA signaling) for configuring the frame structure has the following characteristics:

- The load size is equal to the load size of the format 1C

- placed in CSS (Common Search Space, public search space)

- Each 3 bits indicates a set of TDD frame structures, and eIMTA signaling configures up to 5 sets of TDD frame structures

In the traditional 3GPP LTE system, data transmission can only occur on the licensed spectrum. However, with the sharp increase of traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. The 62rd Plenary of the 3GPP RAN discussed a new research topic, Unlicensed Spectrum Synthesis (RP-132085), with the main purpose of studying the use of non-independent (Non-standalone) deployment of LTE over unlicensed spectrum. Non-independent means that communication on the unlicensed spectrum is associated with the serving cell on the licensed spectrum. An intuitive method is to reuse the concept of CA (Carrier Aggregation) in the existing system. The serving cell deployed on the licensed spectrum is deployed as a Primary Component Carrier (PCC) on the unlicensed spectrum. The serving cell serves as an SCC (Secondary Component Carrier). For unlicensed spectrum, the UE may be configured with more carriers while adopting DFS (Dynamical) considering its uncontrollable/predicted interference level. Frequency Selection (dynamic spectrum selection) mode (in a given sub-frame) selects a part of the carrier from the optional carrier for transmitting data. Further, considering that the bandwidth of the unlicensed spectrum is large, for example, only about 500 MHz of available unlicensed spectrum is available near the 5 GHz carrier frequency, the number of carriers that the UE can work may be larger (far greater than the existing maximum serving cell number -5 ).

When the unlicensed spectrum supports eIMTA and the number of carriers (in combination with DFS technology) on the unlicensed spectrum is greater than 5, since eIMTA signaling configures up to 5 sets of TDD frame structures, multiple carriers share a set of TDD frame structures, bringing The scheduling limit.
