Embodiment 1

[0046] The embodiment of the present application provides a method for competitive uplink data transmission, which is applied to the UE. The schematic flow chart of the method is shown in figure 1 As shown, the method includes:

[0047] Step S101 , receiving high-level configuration information for the transmission of the competitive physical uplink shared channel PUSCH.

[0048]Step S102, according to the high-level configuration information, monitor the first DCI scrambled with the first RNTI in the first physical downlink control channel search space, and determine the competing PUSCH resources according to the monitored first DCI.

[0049] Step S103, transmit data on the contention PUSCH resources.

[0050] In this embodiment of the present application, the UE receives the high-level configuration information transmitted by the competitive physical uplink shared channel PUSCH; the UE monitors the first DCI scrambled with the first RNTI in the search space of the first phy...

Embodiment 2

[0109] The method for competitive uplink data transmission in the first embodiment of the present application is fully and detailedly introduced through the following embodiments:

[0110] The first aspect is the benefit of dynamically scheduled competitive PUSCH resources.

[0111] In the embodiment of this application, the PUSCH resources used for competitive uplink data transmission are dynamically scheduled by the base station through DCI. Compared with the method of preconfiguring through RRC signaling, the advantage of dynamically scheduling competitive PUSCH resources through DCI is that the base station can According to the instantaneous load and the allocation of system resources, the PUSCH resources used for competitive uplink data transmission are dynamically scheduled, and there is no need to statically configure and reserve the PUSCH resources used for competitive uplink data transmission for a long period of time.

[0112] The base station may allocate competitiv...

Embodiment 3

[0274] Based on the same inventive concept as the foregoing embodiments 1 and 2, this embodiment of the present application also provides a UE. The structure diagram of the UE is as follows: Figure 4 As shown, UE50 includes a first processing module 501 , a second processing module 502 and a third processing module 503 .

[0275] The first processing module 501 is configured to receive high-level configuration information for the transmission of the competitive physical uplink shared channel PUSCH;

[0276] The second processing module 502 is configured to monitor the first DCI scrambled with the first RNTI in the first physical downlink control channel search space according to the high-level configuration information, and determine a competitive PUSCH resource according to the monitored first DCI;

[0277] The third processing module 503 is configured to transmit data on the competing PUSCH resources.

[0278] The third processing module 503 is specifically configured to t...

Abstract

The embodiment of the invention provides a competitive uplink data transmission method, UE, a base station, equipment and a computer readable storage medium. The competitive uplink data transmission method comprises the following steps: receiving high-level configuration information transmitted by a competitive PUSCH; monitoring first DCI scrambled by a first RNTI in a first physical downlink control channel search space according to the high-level configuration information, and determining a competitive PUSCH resource according to the monitored first DCI; and transmitting the data on the competitive PUSCH resource. According to the invention, the data transmission efficiency is improved and the UE power consumption is reduced.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a method for competitive uplink data transmission, a UE, a base station, a device, and a computer-readable storage medium. Background technique [0002] For Internet-Of-Things (IOT) UEs such as Machine Type Communications (MTC) and NarrowBand Internet of Things (NB-IoT), due to the limitations of application scenarios, for example, they are often placed underwater Places such as basements and basements where it is not convenient to charge or replace batteries. This type of IOT UE has high requirements on battery life. For some special UEs, it even requires a battery life of 10 years. Therefore, UE power consumption has always been the key improvement of IOT UE. Indicators and related standards are also constantly evolving based on the goal of reducing UE power consumption. [0003] In LTE Rel-16efeMTC and NB-IOT syste...
