Description
Technical Field
The present invention relates to a transmission scheme in a wireless communication system, and more particularly, to a method and apparatus for transmit power adjustment in a narrowband communication system.
Background
To meet the requirement of diversified applications of the Internet of Things, a new narrowband wireless access system NB-IoT (Narrow Band Internet of Things) is introduced in 3GPP (3rd Generation Partner Project) Rel-13. Three modes of operation are supported at the NB-IoT: In-Band Mode (In-Band Mode), Guard-Band Mode (Guard-Band Mode), and stand-alone Mode (standard alone Mode). The three working modes respectively aim at three scenes that NB-IoT carrier waves are positioned in the transmission bandwidth of LTE (Long Term Evolution), in the protection band of LTE and out of the system bandwidth of LTE. Meanwhile, in order to increase the system capacity of the NB-IoT, a non-Anchor Physical Resource Block (non-Anchor PRB) is introduced in addition to an Anchor PRB. So-called Non-anchor physical resource blocks cannot be used for transmitting synchronization and system messages, but can transmit data channels.
The NB-IoT system of Rel-13 is enhanced in 3GPP Rel-14, wherein an important enhancement aspect is to give more functions to the non-anchor physical resource block, such as supporting transmission of a paging channel, supporting transmission of a random access channel, etc.
Disclosure of Invention
Due to the introduction of non-anchor physical resource blocks, a scenario that uplink and downlink respectively support multiple physical resource blocks may occur in an NB-IoT system. For a given NB-IoT terminal device (or user equipment, UE), reference signals on multiple downlink physical resource blocks can be measured at different times. The plurality of measurable downlink physical resource blocks are located in different frequency ranges, so that the path loss (Pathloss) measured on the plurality of measurable downlink physical resource blocks is different. When a plurality of downlink physical resource blocks are distributed in different frequency bands or in different operation modes (such as an in-band mode and an independent mode), the frequency difference between them is large. For example, a frequency band where one downlink physical resource block operating in an independent mode is located is 700MHz-800MHz, a frequency band where another downlink physical resource block operating in an in-band mode is located is 2GHz-2.2GHz, the physical resource block in the independent mode is used as an anchor physical resource block, and the physical resource block in the in-band mode is used as a non-anchor physical resource block, and path loss measured on the two physical resource blocks at this time is very different. In a cellular wireless communication system, the transmission power of uplink transmission is generally related to the downlink path loss (path loss compensation is generally performed), and the difference of the path loss measured on a plurality of downlink physical resource blocks can seriously affect the effectiveness of uplink transmission power control (path loss compensation), thereby causing the degradation of link performance and system performance.
The invention provides a solution for the problem that the uplink transmission power control efficiency is reduced due to inaccurate path loss measurement in an NB-IoT system. By adopting the solution of the invention, more accurate path loss information can be obtained through the frequency of uplink transmission, or the binding of downlink scheduling and uplink transmission, or through a network dynamic configuration mode, thereby ensuring the effectiveness of uplink transmission power control and improving the performance of the system. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE (User Equipment) of the present application may be applied to the base station, and vice versa. Further, the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
