Problems solved by technology

[0004] However, depending e.g. on the number of antenna ports used for MIMO transmission at the eNB transmitter, a relatively large number of reference signals may have to be sent regularly to the RN

Embodiment Construction

[0025] figure 1 One cell of an E-UTRAN network deployed with relay nodes is shown. A base station (DeNB) 2 having a first coverage area 102 communicates directly with one or more user equipments 10 and indirectly with other user equipments 12, 14 and 16 via corresponding relay nodes. Each relay node has its own coverage area, and the coverage area may be completely located in the coverage area of ​​DeNB2 or may partially extend out of the coverage area of ​​DeNB2. The former type of relay nodes 4, 8 can be used to overcome excessive shadowing or to help increase throughput in high traffic (hot spot) areas. The latter type of relay node 6 can additionally be used to extend the effective coverage of eNB2.

[0026] figure 2 A schematic partial cross-sectional view of an example of a user equipment operable to receive data from the DeNB2 at least directly or indirectly via one or more wireless interfaces is shown. The user equipment can be used for various tasks, such as maki...

Abstract

Transmitting physical signals precoded at the physical layer, and transmitting via a physical channel precoded at the physical layer decoding information for use in physical layer decoding of said physical signals; wherein said decoding information is incorporated into one or more data units at a layer higher than the physical layer. Transmitting in a single sub-frame one or more physical reference signals for use in physical layer decoding of a physical channel in a plurality of sub-frames.

Description

technical field [0001] The present invention relates to physical signals used in decoding physical channels. In one embodiment, it involves a physical signal sent from a base station (eNB) to a relay node (RN) for use by the relay node in physical layer decoding of a physical channel from the base station. Background technique [0002] Relay is a technology proposed for 3GPP LTE-Advanced (LTE-Advanced) network. Base Stations (eNBs) operate in Enhanced UTRAN (E-UTRAN) cellular networks; and Relay Nodes (RNs) are deployed to extend coverage in cellular networks and also help provide high shadow environments (such as inside buildings) and high data rate coverage for high traffic hotspots. exist figure 1 An example of how to deploy an eNB of an LTE radio access network with a fixed relay node is shown in . The tasks of the RN include forwarding data between the eNB and the communication device, and optionally also supporting communication from the communication device to the...
