摘要： A power control applied to a radio network controller (40) when a user equipment (300) is in communication with a serving radio base station (10) and at least one other radio base station (20) involves the radio network controller (40) providing a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The radio network controller (40) generates an updated power quality target for a reference control channel based on the quality representation and transmits the updated power quality target to at least one of the serving radio base station (10) and the at least one other radio base station (20). Alternatively, the radio network controller (40) generates an updated power offset for the uplink control channel (12) relative a reference control channel based on the quality representation and transmits the updated power offset to the user equipment (300).

摘要： An uplink power control that is applied to a user equipment (300) when in communication with a serving radio base station (10) and at least one other radio base station (20) involves generating a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The quality representation is compared to a threshold value and this comparison defines a selective processing of transmit power control commands received by the user equipment (300) from the serving and/or non-serving radio base stations (10, 20).

摘要： Random access coverage is assured while at the same time supporting high uplink data rates in a same service area served by a base station. A set of radio resources are shared by multiple mobile terminals for transmitting uplink to the base station including requests for access to service from the base station and transmissions for active connections with the base station. A first repeating time period and a second different repeating time period are defined. Uplink transmission grants are scheduled for active connections that permit use of a greater amount of the radio resources during the first repeating time period. Uplink transmission grants are also scheduled for active connections that permit use of a smaller amount of those resources during the second repeating time period. At least some random access requests to the base station are controlled to occur only during the second repeating time period.

摘要： Control of downlink transmissions associated with a first cell (124) in a cellular communication system (100) is described. A plurality of antennas (117) at different locations are configured to transmit downlink signals associated with the first cell. A subset of the plurality of antennas is caused to transmit a respective probing signal intended for reception by a mobile communication terminal (106). Feedback information is received that is indicative of reception in the mobile communication terminal of the probing signals. At least one specific antenna is selected for downlink transmissions to the mobile communication terminal, based at least in part on the feedback information and the at least one specific antenna is caused to perform downlink transmissions to the mobile communication terminal.

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.

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误码率（BLER）统计信息来确定小区是否超载; 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对非GBR用户的负载净空，而不违反性能的GBR用户。
