Abstract

Abstract:

TD-LTE is deployed in the same frequency band to improve spectral usage，which also makes the inter-cell interference（ICI）become one of the main bottlenecks of the network capacity. The test results of the large scale TD-LTE field trial demonstrate more than 70% UE could detect signals from multiple cells. The coordinated multi-point processing（CoMP）technology adopts several cell to jointly transmit/receive signals for UE，which could effectively reduce ICI. Several kinds of uplink CoMP scheme were studied. Especially，the field trial of the uplink CoMP in the realistic TD-LTE network was introduced. The test results show that the ce11-edge UE could achieve 50%～100% throughput gain via the uplink CoMP technology，which significantly improves the user experience.

Key words: TD-LTE, inter-cell interference, uplink coordinated multipoint processing

Interference analysis of TD-LTE downlink signal on S-band pulse radar fuse Abstract:Concerning that the TD-LTE downlink signal and pulse radar fuze signal may be interfered within 2 300 to 2 400 MHz band of S-band,the method of calculating the signal-to-interference ratio at the pulse radar fuse receiver was used.And the isolation distance that the TD-LTE downlink signal did not interfere the pulse radar fuze signal under the condition of other factors determined was obtained.The validity of the conclusion through the link level simulation was verified.At the same time,it was also obtained when the horizontal distance between the two was isolated distance,the transmission power of the base station was increased (or the fuze transmission power was reduced),the ground effective reflection area was reduced,the fuse will also be interfered by TD-LTE downlink signal.
