Problems solved by technology

Since the autonomously scheduled uplink transmission is not completely controlled by the scheduling of the eNB, the subframe configured for the autonomously scheduled uplink transmission cannot be in the same position as the downlink subframe and / or uplink subframe in other transmissions, so the available resources for the autonomously scheduled uplink transmission are limited. Therefore, the transmission efficiency of autonomously scheduled uplink transmission is low

Embodiment 1

[0087] An embodiment of the present invention provides a transmission method, including: the user terminal UE detects the common physical downlink control channel C-PDCCH (that is, the PDCCH scrambled by CC-RNTI) and its indication information, uses the first parameter to correspond to the indication information Autonomously scheduled uplink transmission on resources. The indication information of the C-PDCCH contains the resources that can be used for autonomously scheduled uplink transmission. Only when the C-PDCCH is detected can the resources corresponding to the indication information be used for autonomously scheduled uplink transmission. In this way, the resources in other transmission methods can be used. Available resources for autonomously scheduled uplink transmission.

[0088] In the transmission method in this embodiment, autonomously scheduled uplink transmission is performed on the resources corresponding to the indication information of C-PDCCH through the dete...

Embodiment 2

[0104] An embodiment of the present invention provides a transmission method, which includes: if the user terminal detects that this The discovery reference signal DRS of the cell, the user terminal UE performs autonomous scheduling uplink transmission within the discovery reference signal measurement time configuration window DMTC window.

[0105] Specifically, the DMTC window is used for the eNB to send DRS to the UE. After the UE receives the DRS in the DMTC window, it can autonomously schedule uplink transmission on the GUL available subframes in the remaining DMTC window to utilize the resources of the DMTC window.

[0106] In the transmission method in this embodiment, after the UE receives the DRS of the local cell, it performs autonomously scheduled uplink transmission in the DMTC window, and makes full use of the resources of the DMTC window, thereby improving the transmission efficiency of autonomously scheduled uplink transmission.

[0107] Specifically, within the ...

Embodiment 3

[0109] An embodiment of the present invention provides a transmission method, including: a user terminal UE uses a first parameter to perform autonomously scheduled uplink transmission within the period of periodic non-anchor Uplink (periodic non-anchor UpLink) scheduled based on base station eNB, and the first parameter It is used to make frequency division multiplexing FDM or time division multiplexing TDM between autonomously scheduled uplink transmission and periodic non-anchor uplink periodic non-anchor UpLink transmission within the periodic non-anchor uplink periodic non-anchor UpLink time. Periodic non-anchor uplink (periodic non-anchor Uplink) transmission is also called pseudo-periodic uplink (pseudo periodic Uplink) transmission.

[0110] In the transmission method in this embodiment, frequency division multiplexing (FDM), time division multiplexing (TDM) and code division multiplexing are performed by autonomously scheduling uplink transmission and periodic non-anch...

Abstract

Provided in the embodiments of the present application are a transmitting method and a user terminal, which relate to the field of mobile communication technology. The invention can improve the transmission efficiency of autonomous scheduled uplink transmission. The transmitting method comprises: a user terminal, on the basis of the detection of a common physical downlink control channel (CPDCCH) and indication information thereof, using a first parameter to perform autonomous scheduled uplink transmission on resources corresponding to the indication information.

Description

【Technical field】 [0001] The present invention relates to the technical field of mobile communication, in particular to a transmission method and a user terminal. 【Background technique】 [0002] The mobile communication system refers to a system in which service providers provide communication services for user terminals (such as mobile phones) by deploying wireless access network equipment (such as base stations) and core network equipment (such as Home Location Register, HLR), etc. . Mobile communication has experienced the first generation, second generation, third generation, and fourth generation. The first generation of mobile communication refers to the initial analog, voice-only cell phone standard, which mainly uses analog technology and frequency division multiple access (FDMA) access method; the second generation of mobile communication introduces Digital technology improves network capacity, voice quality and confidentiality, represented by "Global System for M...
