Embodiment 1

[0093] In this embodiment, the method provided by the present invention is described in detail for uplink data information transmission.

[0094] The base station allocates shared resources for transmitting uplink data information to a group of terminals in the cell that require low-latency transmission, and uses G-RNTI scrambled control channel scheduling group information for allocation. The allocated shared resources account for 30% of the total resources and are located at a position with a lower number in the frequency domain in the system bandwidth. At this time, the shared resources include temporary resources, and the temporary resources account for 50% of the shared resources.

[0095] After the base station allocates shared resources, terminals with low-latency transmission requirements perform autonomous transmission and send uplink data in the shared resource area. Terminals 1-10 all use different frequency domain resource units to send uplink data in subframe n, ac...

Embodiment 2

[0099] In this embodiment, the method provided by the present invention is described in detail for uplink data information transmission.

[0100] The base station allocates shared resources for transmitting uplink data information to all terminals in the cell that require low-latency transmission, and uses SI-RNTI scrambled control channel scheduling system information for allocation. The allocated shared resource accounts for 30% of the total resource and is located at a position with a lower frequency domain position number in the system bandwidth.

[0101]After the base station allocates shared resources, terminals with low-latency transmission requirements perform autonomous transmission and send uplink data in the shared resource area, and some terminals of terminals 1-100 use different frequency domain resource units to send uplink data in subframe n, according to Select 1, 2, 4, and 8 PRB for the respective data packet sizes. The base station receives and detects 80% of...

Embodiment 3

[0106] In this embodiment, the method provided by the present invention is described in detail for uplink data information transmission.

[0107] The base station allocates shared resources for transmitting uplink data information to all terminals in the cell that require low-latency transmission, and uses SI-RNTI scrambled control channel scheduling system information for allocation. The allocated shared resource accounts for 40% of the total resource and is located at a position with a lower frequency domain position number in the system bandwidth.

[0108] After the base station allocates shared resources, terminals with low-latency transmission requirements perform autonomous transmission and send uplink data in the shared resource area, and some terminals of terminals 1-100 use different frequency domain resource units to send uplink data in subframe n, according to Select 1, 2, 4, and 8 PRB for the respective data packet sizes. The base station receives and detects 80% o...

Abstract

The present invention provides a method and device for controlling uplink data transmission; the method includes: a base station allocates shared resources for transmitting uplink data to at least two terminals in a cell; the base station configures the at least two terminals in the cell autonomous transmission over the shared resources described above.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for controlling uplink data transmission. Background technique [0002] With the 4th generation mobile communication technology (4G, the 4th Generation mobile communication technology) long-term evolution (LTE, Long-Term Evolution) / advanced long-term evolution (LTE-Advance / LTE-A, Long-Term Evolution Advance) system commercialization is increasing The requirements for technical indicators of the next-generation mobile communication technology, that is, the fifth generation mobile communication technology (5G, the 5th Generation mobile communication technology) are getting higher and higher. It is generally believed in the industry that the next-generation mobile communication system should have the characteristics of ultra-high speed, ultra-high capacity, ultra-high reliability, and ultra-low delay transmission characteristics. The index of ultra-low latenc...
