摘要： Techniques are disclosed for synchronizing frequency among a cluster of coordinated transmission points cooperating in a coherent joint transmission. In some embodiments, one transmission point is set (510) as a reference transmission point for a group of coordinated transmission points. Each of one or more other transmission points in the group receives (530) a specified downlink reference signal from the reference transmission point, measures (540) its frequency offset relative to the reference point, and compensates (550) the frequency offset in baseband processing or by a radio adjustment. Which transmission point acts as the reference transmission point is statically defined, in some embodiments, or dynamically configured, in others. Likewise, which time-frequency resources are used for the reference signal may be statically defined or dynamically configured. In some embodiments, information identifying the reference transmission point and/or specifying the radio resource locations and durations of the reference signal is distributed to the synchronizing transmission points.

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 BLERstatistic 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 RoTtgt, 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.
