Problems solved by technology

Thus, reusing UE stacks for relays is not efficient enough
For example, if there are many relays constantly communicating with the eNodeB, there will be significant signaling overhead, such as grants and assignments on the PDCCH

Embodiment Construction

[0024] figure 1 An embodiment of a wireless network 100 for serving a UE 102 is shown. In one embodiment, the wireless network 100 has a network core such as LTE Evolved Packet Core and an air interface such as E-UTRAN (Evolved UMTS Terrestrial Radio Access Network). The LTE Evolved Packet Core includes the MME (Mobility Management Entity) 104, which is the control node for the LTE access network and handles idle mode UE tracking and paging procedures including retransmissions. The LTE-Evolved Packet Core also includes an S-GW (Serving Gateway) 106 for routing and forwarding user data packets. The S-GW 106 also functions as a mobility anchor for the user plane during inter-base station handovers and as an anchor for mobility between LTE and other 3GPP technologies. The air interface of the wireless network 100 includes base stations 108 , such as eNodeBs, and one or more repeaters 110 associated with each base station 108 . Various interfaces such as S1-CP and S1-UP enable ...

Abstract

Repeater reporting in wireless networks is achieved by efficiently allocating radio resources according to the nature or criticality of the type of repeater reporting. According to an embodiment, a method of communicating with a repeater located in a wireless network includes instructing the repeater when to transmit reports according to a mapping of different repeater reporting categories to one or more different reporting schemes. Receive reports from repeaters based on the repeater report category and corresponding reporting scheme. According to another embodiment, a method of reporting information from a relay to a network node of a wireless network comprises generating, at the relay, reports of different classes for transmission to the network node. A reporting scheme associated with each reporting category is identified, and each report is transmitted to the network node in accordance with the reporting scheme identified for the corresponding reporting category.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(e), this application claims the benefit of priority from U.S. Provisional Application 61 / 161,932, filed March 20, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to repeater operation in wireless networks, and more particularly to repeater control and reporting. Background technique [0004] A repeater is a network node used to enhance the signal quality of the link between the base station and user equipment. By using repeaters, coverage and cell edge data rates can be significantly enhanced. There are three main categories of repeaters: Layer 1, Layer 2, and Layer 3 repeaters. Layer 1 repeaters, also known as Advanced Repeaters, are expected to be one of the potential technology components for LTE (Long Term Evolution) Advanced, which is an enhancement of 3GPP (3rd Generation Partnership Project) LTE. Unles...
