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] like 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 transmit...

Abstract

The invention provides a power control method and device for short transmission time interval transmission and relates to the technical field of communication. According to the method and the device,new excessive time definition is prevented from being introduced for the short TTI transmission and work can be carried out according to a time template defined in an existing 3GPP 36.101 protocol, thereby finishing power measurement. The method comprises the steps of determining first target transmitting power corresponding to a to-be-processed object in a sub-frame when the sub-frame comprises aplurality of pieces of short transmission time interval TTI transmission; and sending the short TTI transmission in the to-be-processed object according to the first target transmitting power corresponding to the to-be-processed object. The method and the device are mainly applied to power control for the 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...
