System and method for downlink and uplink parameter information transmission in a multi-hop wireless communication system

摘要

A method for transmission of information about downlink and uplink parameters of a intermediate apparatus link in a multi-hop wireless communication system, the system comprising a first node apparatus, a second node apparatus and one or more intermediate apparatuses, each said apparatus being operable to transmit and receive information along a series of links forming a communication path for downlink and uplink communication, the communication path extending between the first node and second node apparatuses via the or each intermediate apparatus, each link comprising either a first node link between the first node apparatus and a said intermediate apparatus or an intermediate apparatus link between a said intermediate apparatus and a said apparatus which is not the first node apparatus, and the system having access to a minimum allocation unit for allocating time and transmission frequency bandwidth, the method comprising: obtaining values of downlink and uplink parameters for a particular intermediate apparatus link; mapping both values onto a single minimum allocation unit and transmitting them towards the first node apparatus.

1. A method for transmission of information about downlink and uplink parameters of an intermediate apparatus link in a multi-hop wireless communication system, the system comprising a base station apparatus, a user terminal apparatus and one or more intermediate apparatuses, each said apparatus being operable to transmit and receive information along a series of links forming a communication path for downlink and uplink communication, the communication path extending between the base station and user terminal apparatuses via the one or more intermediate apparatuses, and including a base station link between the base station apparatus and one of the intermediate apparatuses and an intermediate apparatus link between one of the intermediate apparatuses and an apparatus which is not the base station apparatus, and the system having access to a minimum allocation unit for allocating time and transmission frequency bandwidth, the method comprising:
obtaining values of downlink and uplink parameters for the intermediate apparatus link, the downlink parameter being for transmission along the intermediate apparatus link towards the user terminal and the uplink parameter being for transmission along the same intermediate apparatus link towards the base station; and mapping both values onto a single minimum allocation unit and transmitting them towards the base station apparatus, wherein the system is an OFDM or OFDMA system and both values are mapped onto a single slot.
