Resource mapping method and device

Abstract

The embodiment of the invention relates to the wireless communication technology, in particular to resource mapping method and device, which is used for solving the problem that RN equipment can not easily map resources onto SC-FDMA symbols according to the traditional scheme because the SC-FDMA symbols of upstream backhaul subframe edges need to be occupied as GP when upstream backhaul subframesare adjacent to non-upstream backhaul subframes in the prior art. The method of the embodiment of the invention comprises the following steps of: converting data information into data complex sequences, wherein the number of the SC-FDMA symbols occupied by the data complex sequences is not greater than the number of first usable SC-FDMA symbols used for carrying the data complex sequences, and inaddition, the first usable SC-FDMA symbols comprise usable SC-FDMA symbols used for carrying the data complex sequences and second usable SC-FDMA symbols partially used for carrying demodulation pilot frequency complex sequences; and respectively mapping the complex sequences and the demodulation pilot frequency complex sequences onto the first usable SC-FDMA symbols and rest partial symbols of the second usable SC-FDMA symbols.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a resource mapping method and device. Background technique [0002] After the introduction of relay nodes into the LTE-A (Long Term Evolution-Advanced) system, there are three wireless links in the Relay-based mobile communication system: figure 1 as shown, [0003] Nodes include: [0004] Donor-eNB: An eNB that is wirelessly connected to the RN device, abbreviated as DeNB; [0005] Relay-Node: an entity existing between DeNB and UE, abbreviated as RN device; [0006] Relay-UE: UE that performs data interaction with RN equipment, abbreviated as R-UE; [0007] Macro UE: a UE that directly exchanges data with the DeNB. [0008] Interfaces include: [0009] Un interface: the interface between the RN device and the DeNB; [0010] Uu interface: interface between UE and RN equipment. [0011] Wireless links include: [0012] Backhaul link: Backhaul link, the link co...

Problems solved by technology

[0018] Embodiments of the present invention provide a method and device for resource mapping, which are used to solve the problem that the LTE-A system existing in the prior art needs to occupy a resource when the uplink backhaul subframe and the non-uplink backhaul subframe The SC-FDMA symbols on the edge of the uplink backhaul subframe are used as GP, which reduces the number of SC-FDMA symbols available in PUCCH, which makes it difficult for RN equipment to map data and demodulation pilots to SC-FDMA symbols.
