Description

Method and device used in user and base station of wireless communication
Technical Field
The present application relates to a method and an apparatus for transmitting a wireless signal in a wireless communication system, and more particularly, to a transmission scheme and an apparatus for a wireless signal in a wireless communication system supporting power adjustment.
Background
According to the conclusion of 3GPP (3rd Generation Partner Project) RAN1(Radio Access Network) #88 conference, the number of symbols occupied by a long duration PUCCH (Physical Uplink Control Channel) in a slot (slot) is variable. According to some 3GPP papers (e.g., R1-1701647), the number of symbols occupied by a long-duration PUCCH on one slot may vary from 4 to 14. Such a large variation range brings new problems to the PUCCH design.
Disclosure of Invention
The inventor finds that, in a dynamic TDD (Time Division Duplex) system, a base station may notify a user equipment of transmission directions corresponding to different symbols in a Time slot by using a dynamic signaling, so as to improve flexibility of uplink and downlink resource utilization. In this case, the user equipment is prone to error in understanding the PUCCH length. When the understanding of the PUCCH length by different user equipments is inconsistent, additional interference between user equipments may be caused. In addition, energy used for transmitting the PUCCH may increase as the PUCCH length increases, which may result in waste of user equipment energy in case of a longer PUCCH.
In order to solve the above problem, the inventors found that the time domain resource occupied by the PUCCH can be divided into two parts. The configuration of the first part of time domain resources is fixed or slowly changed and is configured by high layer signaling. The configuration of the second part of time domain resources is dynamically variable and is configured by dynamic signaling. The user equipment transmits the PUCCH with different powers on the first part of time domain resources and the second part of time domain resources, and the transmission power on the second part of time domain resources is lower than that on the first part of time domain resources, so that extra user equipment interference caused by inconsistent understanding of different user equipment on the length of the second part of time domain resources is reduced. Another advantage of the above method is that when the PUCCH length is longer, by using lower transmit power on the second partial time domain resource, the transmit power on the entire PUCCH is reduced on the premise of ensuring PUCCH coverage, and power efficiency is improved.
The present application discloses a solution to the above finding. It should be noted that although the initial motivation of the present application is for PUCCH, the present application is also applicable to other physical layer channels. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
The application discloses a method used in user equipment for wireless communication, which comprises the following steps:

Said T and said X1 are each positive integers.
As an embodiment, the above method has the advantages that the X1 multicarrier symbols are configured by high-layer signaling, and have higher reliability, and the multicarrier symbols other than the X1 multicarrier symbols are configured by dynamic signaling, and have higher flexibility.
