Problems solved by technology

Since the power of sPUCCH / sPUSCH may vary, it is necessary to add the definition of excessive time between each short TTI transmission for power adjustment, which makes it impossible to work according to the time template defined in the existing 3GPP 36.101 protocol

Embodiment Construction

[0115] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0116] In the embodiment of the present invention, in order to ensure that the time template defined in the existing 3GPP 36.101 protocol can be used to complete the power measurement, when a subframe contains multiple short TTI transmissions, power control is performed on each short TTI transmission , to ensure the same transmit power for each short TTI transmission.

[0117] Such as image 3 As shown, the power control method for short transmission time interval transmission in Embodiment 1 of the present invention is applied to a terminal, including:

[0118] Step 301. When a subframe contains multiple short transmission time interval TTI transmissions, determine a first target trans...

Abstract

The present invention provides a power control method and device for short transmission time interval transmission, which relates to the field of communication technology, to avoid introducing a new excessive time definition for short TTI transmission, and ensure that the time template defined in the existing 3GPP 36.101 protocol can be followed work to complete the power measurement. The present invention includes: when a subframe contains multiple short transmission time interval TTI transmissions, determining the first target transmit power corresponding to the object to be processed in the subframe; transmitting according to the first target corresponding to the object to be processed Power sends short TTI transmissions within the pending object. The present invention is mainly used in power control of short TTI transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a power control method and device for short transmission time interval transmission. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as the ITU have defined higher user plane delay performance requirements for future mobile communication systems. One of the main methods to reduce user delay performance is to reduce the length of Transmission Time Interval (Transmission Time Interval, TTI). [0003] The existing LTE FDD (Long Term Evolution Frequency Division Duplexing, Long Term Evolution Frequency Division Duplexing) system uses a frame structure (frame structure type 1, FS1 for short), and its structure is as follows figure 1 shown. In the FDD system, different carrier frequencies are used for uplink and downlink transmission, and the same frame structure is used for both uplink...
