METHOD FOR WIRELESS BACKHAUL FREQUENCY BAND FLEXIBLE ALLOCATION

摘要

The present invention provides a method for wireless backhaul frequency band flexible allocation. It is able to use the uplink band of FDD band as the wireless backhaul uplink and downlink band of small cells. When the status is having a plurality of FDD bands and a heterogeneous network with big cells and one or more small cells, the present invention is able to efficiently use uplink band of the FDD band as the wireless backhaul band of the one or more small cells.

主权项

1. A method for wireless backhaul frequency band flexible allocation, comprising steps of:
S11: setting a first FDD band in a big cell of a heterogeneous network and a second FDD band in a small cell of the heterogeneous network; S12: the first FDD band of the big cell comprising a first FDD uplink band and a first FDD downlink band, the second FDD band of the small cell comprising a second FDD uplink band and a second FDD downlink band; S13: the uplink band of the first FDD band comprising a Physical Uplink Control CHannel (PUCCH) and a Physical Uplink Shared CHannel (PUSCH) located in two sides of the band, flexibly allocating a wireless backhaul uplink band in the PUSCH of the first FDD band as the uplink wireless backhaul among the big cell and small cell (data flow from the small cell to the big cell), wherein the allocation of the wireless backhaul uplink band is to first allocate the PUSCH of the PUCCH near the higher frequency; and S14: the uplink band of the second FDD band comprising a Physical Uplink Control CHannel (PUCCH) and a Physical Uplink Shared CHannel (PUSCH) located in two sides of the band, flexibly allocating a wireless backhaul downlink band in the PUSCH of the first FDD band as the downlink wireless backhaul among the big cell and small cell (data flow from the small cell to the big cell), wherein the allocation of the wireless backhaul downlink band is to first allocate the PUSCH of the PUCCH near the higher frequency.
