[0049] The first embodiment of the present invention, such as figure 2 As shown, a method for resource unit mapping includes the following specific steps:

[0050] Step s101, classifying RS, PS, SS and PBCH as the first type of physical channels and signals, and transmitting them to the first port of the dual-port RAM through the first multiplexer, and further, passing the RS and PBCH through the third multiplexer The selector passes to the first multiplexer.

[0051] Step s102, classifying PDSCH, PDCCH, PHICH and PCFICH as the second type of physical channels and signals, and transmitting them to the second port of the dual-port RAM through the second multiplexer, further, passing PDCCH, PHICH and PCFICH through the fourth The multiplexer transmits to the second multiplexer.

[0052] It should be noted that there is no strict sequence for step s101 and step s102, and they can be performed at the same time.

[0053] Step s103, uniformly reset the downlink resource grid dat...

Abstract

The invention discloses a resource unit mapping method and device. The method comprises the following steps: dividing each physical channel and signals into two types, and transmitting to two ports of a dual-port RAM (Random-Access Memory) through a multi-path selector; uniformly setting the downlink resource grid data to be zero by uniformly resetting the dual-port RAM; traversaling all symbols in each subframe in a time domain, and simultaneously mapping the two types of physical channel and signals in the frequency domain of each symbol. The device comprises a multi-path selection module, a control signal providing module and a dual-port mapping module. Compared with the prior art, the resource mapping pattern is calculated for a downlink resource grid without occupying a great deal of logic resources; and the two-path data can be processed simultaneously through the two ports of the dual-port RAM, thereby the mapping efficiency is further improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for resource unit mapping. Background technique [0002] A wireless communication system based on OFDMA (Orthogonal Frequency Division Multiple Access) / SC-FDMA (Single Carrier-Frequency Division Multiple Access) can flexibly allocate resources in the frequency domain Allocation and scheduling, multiplexing and mapping "data blocks" from multiple channels into a shared data channel. [0003] Taking the downlink physical resource mapping of the physical layer of the LTE (Long Term Evolution, long-term evolution) system based on OFDMA as an example, according to the downlink physical resource mapping and scheduling mechanism, the following LTE system physical channels and signals: PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), PBCH (Physical Broadcast Channel, Physical Downlink Broadcast Channel), PHICH (Physic...
