Embodiment Construction

[0075] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the descriptions of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only of the present invention. For some embodiments, those of ordinary skill in the art can also obtain other drawings based on these drawings without paying creative efforts.

[0076] The resource restricted subframe (Resource Restricted Subframe, RRS) technology is adopted. When the resource is the power of the High speed-physical downlink shared channel (HS-PDSCH), the RRS is equivalent to the almost blank subframe (Almost blank subframe, ABS). That is, the second cell and the first cell coordinately schedule respective UEs according to a certain criterion. In the ABS subframe, the first cell reduces the transmission power of the HS-PDSCH subframe aligned ...

Abstract

The present invention is applicable to the technical field of wireless communication, and provides a quality measurement method, user equipment and quality measurement system. The method includes: the user equipment UE receives the resource-restricted subframe RRS information sent by the network side equipment; the UE according to The RRS information performs downlink channel quality measurement and / or downlink physical layer channel quality measurement. In the present invention, the UE performs downlink channel quality measurement or downlink physical layer channel quality measurement according to the RRS information sent by the network side equipment. This measurement method is different from the existing measurement method, and is a channel measurement method limited to RRS subframes. This measurement method can enable the second cell to enjoy a larger extension range, and enable the UE in the second cell in the RE area to enjoy more accurate downlink channel quality measurement results or downlink physical layer channel quality measurement results.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a quality measurement method, system and user equipment. Background technique [0002] With the development of communication technology, more and more new technologies emerge. Wideband Code Division Multiple Access (WCDMA) is currently the most widely used third-generation wireless communication system. How to evolve the WCDMA system to meet the user's demand for high-speed uplink and downlink data transmission is the most important research work in the field of wireless communication. Starting from R5, a series of important technologies have been introduced into WCDMA to improve uplink and downlink data transmission rates: High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA ), Multiple-Input Multiple-Out-put (MIMO), 64-phase quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM). After several version...
