Embodiment Construction

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0033] In order to facilitate the understanding of the present invention, the manner of resource indication in LTE is briefly introduced below.

[0034] There are mainly three ways for resource indication in LTE: resource indication type 0, resource indication type 1, and resource indication type 2. Specifically, a detailed definition is given in 36.213, and a brief description is as follows:

[0035] Resource indication type 0:

[0036] The implementation of resource indication type 0 in the LTE system is by using P resource blocks (R...

Abstract

The invention provides a transmission and indication method for a relay system, which comprises the following steps: using a base station to send indication information to a terminal, wherein the indication information is used for indicating frequency band resource information of a special region transmitted by a relay downlink backhaul and the size of a control signal channel transmission regionof the special region; using the base station to send scheduling signaling for transmitting downlink data to the terminal; and using the base station to send the downlink data on corresponding frequency band resources to the terminal. The technical scheme can solve the problem of utilizing the resources which are not occupied in the resources of a relay downlink backhaul link and fully utilize the downlink resources for providing services for users by carrying out distribution and indication on all the reserved resources which are not occupied by the relay downlink backhaul link.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, the present invention relates to a method and device for transmission and indication of a relay system. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of LTE (Long Term Evolution, long-term evolution) system as a 3G system. The goal is to develop 3GPP wireless access technology towards Evolution for high data rate, low latency and optimized packet data applications. In future mobile communication systems, such as B3G (Beyond three Generation) or LTE-A, the system will provide higher peak data rate and cell data throughput, so the system also needs wider transmission bandwidth. At present, there are very few unallocated radio frequency resources below 2GHz, and part or all of the bandwidth required by the B3G system can o...
