摘要： The present invention discloses schemes to perform load control taking uplink BLER statistics into account. An uplink load control method and apparatus are provided in a wireless communication system. The uplink load control method comprises estimating uplink load budget in a cell of the wireless communication system; determining whether the cell is over-loaded based on Block Error Rate (BLER) statistics of non- Guarded Bit Rate (non-GBR) users in the cell and/or Fast Congestion Control (FCC) action statistics in the cell; decreasing the uplink load budget if it is determined that the cell is over-loaded; and increasing the uplink load budget if it is determined that the cell is not over-loaded. Preferably, increasing or decreasing of the uplink load budget is based on the BLER stastics BLER statistic of targeted users by FCC. By means of the BLER and FCC status, BLER of EUL users can be controlled in an acceptable range while maximizing the benefit of FCC in improving load utilization and consequently uplink throughput as much as possible. On the other hand, the uplink load control method can further comprises adjusting a RoT target RoT tgt , based on BLER statistics of Guarded Bit Rate (GBR) users in order to increase load headroom available for non- GBR users in appropriate conditions without violating the performance of GBR users.
摘要翻译：本发明公开了进行上行BLER统计的负载控制的方案。在无线通信系统中提供上行链路负载控制方法和装置。上行链路负载控制方法包括估计无线通信系统的小区中的上行负载预算; 基于小区中的非保密比特率（非GBR）用户和/或快速拥塞控制（FCC）动作统计信息中的块错误率（BLER）统计信息来确定该小区是否超载; 如果确定小区被超载，则减小上行链路负载预算; 并且如果确定该小区未被过载，则增加上行链路负载预算。优选地，上行负载预算的增加或减少是基于FCC的目标用户的BLER stastics BLERstatistic。通过BLER和FCC状态，可以将EUL用户的BLER控制在可接受的范围内，同时最大限度地提高FCC的优点，尽可能地提高负载利用率，从而提高上行链路吞吐量。另一方面，上行链路负载控制方法还可以包括基于保护比特率（GBR）用户的BLER统计来调整RoT目标RoTtgt，以便在适当的条件下增加非GBR用户可用的负载净空，而不违反性能的GBR用户。

摘要： Methods and radio network nodes (BS1, BS2) for alleviating interference on downlink radio signals in a victim User Equipment, UE (T1, T2), caused by uplink transmission from an aggressor UE (T2, T1). The interference occurs during a flexible subframe in which the direction of signal transmission is variable between uplink and downlink in different radio frames. A first radio network node (BS1) detects (4:1) that a first UE (T1) that is served by the first radio network node (BS1) is one of the victim and aggressor UEs. The first radio network node (BS1) identifies (4:2) a second radio network node (BS2) employing a subframe scheme such that uplink transmission from the aggressor UE may overlap at least partly with downlink reception in the victim UE during the flexible subframe. The first radio network node (BS1) sends (4:3) a notification to the second radio network node, indicating that the first UE is served by the first radio network node. The second radio network node (BS2) is thereby triggered to execute (4:5) an interference mitigation action for alleviating the interference when serving a second UE (T2) being the other one of the victim and aggressor UEs.
