Embodiment Construction

[0167] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0168] As the system bandwidth increases at high frequencies, the number of resource blocks corresponding to the system bandwidth also doubles. For example, when the system bandwidth is 500M and 1G, the number of resource blocks corresponding to 10M is 2.5 times and 5 times respectively. As TDD is the mainstream multiple access multiplexing m...

Abstract

The invention provides a communication device and a communication method of an uplink reference signal. The uplink reference signal of a UE is transmitted by a user equipment according to the bandwidth configuration information of the reference signal of the UE, the frequency hopping interval information of the reference signal of the UE and the frequency domain position parameter. As the frequency hopping interval information of the reference signal of the UE is added as a parameter, when the uplink reference signal is subjected to frequency hopping, further sampling reduces the number of measurements, thereby improving the efficiency of channel quality measurement.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an uplink reference signal communication device and method. Background technique [0002] Spectrum is a very expensive resource in wireless communications. Modern communication systems, such as Global System for Mobile Communication (GSM for short) system, Code Division Multiple Access (CDMA for short) 2000 / Wideband Code Division Multiple Access (Wideband Code Division Multiple Access for short: WCDMA) systems and Long Term Evolution (LTE for short) systems generally work on carrier frequencies below 3 GHz. With the popularization of smart terminals, especially the emergence of video services, the current spectrum resources have been difficult to meet the explosive growth of users' demand for capacity. High-frequency frequency bands with larger available bandwidths, especially millimeter-wave frequency bands, are increasingly becoming candidate frequency ...
