Abstract: Methods for downlink power control in wireless communication systems are provided. In response to a transmitter power change request from a mobile terminal (110) over a wireless connection, a base station (122) determines a power control parameter based on its current total transmitter power PDL. The power control parameter preferably relates to a maximum connection-specific transmitter power, a power step size and/or a power increase probability, and is used by the base station to distribute transmitter power pi to the connection.

Abstract: Each base station in a cellular telephone system includes a signal strength measurement device operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed against the measured uplink interference for those frequencies having more than a threshold number of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment at either call set-up or hand-off from the least (adjusted) interfered frequency.

Abstract: A base station (BS) and method for controlling handover in a wireless communication system. The BS serves a first cell in a first cell layer overlapping with a second cell layer, and the first cell has a different distribution of configured amounts of uplink and downlink resources than a second cell in the second cell layer. The BS monitors amounts of uplink and downlink resources utilized by a user equipment (UE) in the first cell and adjusts at least one parameter controlling handover of the UE to the second cell based on the resources utilized by the UE, and on information regarding configured amounts of uplink and downlink resources in the first and second cells. This increases the likelihood that the UE will be served by one of the first and second cells in which the configured amounts of resources better matches the amounts of resources utilized by the UE.

Abstract: Embodiments herein relate to a method in a first communication node (201) for estimating pre-coding weights for transmission on a radio channel (205) between the first node (201) and a second communication node (203) in a communication network (200). The first node (201) comprises at least two transmit antennas. Each transmit antenna is configured to transmit on each of at least two sub-bands. The first node (201) obtains at least two pre-coding reports. Each pre-coding report is for a different time instance. Each pre-coding report comprises pre-coding weights or indications to pre-coding weights. The pre-coding weights are associated with each transmit antenna and with each sub-band. For each transmit antenna, the first node (201) estimates pre-coding weights for at least one of the sub-bands based on the pre-coding weights in the obtained pre-coding reports. The estimated pre-coding weights are different from a most resent of the obtained pre-coding reports.

Abstract: According to some embodiments, there is provided a base station system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL value, which can lead to the UE lowering its output power.

Abstract: A method in a wireless network containing a first node and an adjacent second node for determining an uplink received power target value of the second node to be used by a user equipment which is to be served by the second node includes establishing the uplink received power target value of the first node. The method also includes obtaining the downlink power capacity of the first node and obtaining the downlink power capacity of the second node. Additionally, the method includes calculating the difference in downlink power capacity between the first node and the second node and determining the uplink received power target value of the second node based on the calculated difference in downlink power capacity between the nodes and the established uplink received power target value of the first node.
