摘要： Random access coverage is assured while at the same supporting high uplink data rates in a same service area served by a base station. The service area includes first and second co-sited cells. The first co-sited cell is associated with a first uplink frequency, and the second co-sited cell is associated with a second uplink frequency. The first cell allows a lower uplink load and provides a greater coverage than the second cell. The second cell allows a higher rise over thermal (RoT) value than the first cell. Random access channel requests are initially directed to the first cell using the first uplink frequency. One of the co-sited cells is selected for supporting the connection depending on one or more factors. Example factors include a priority associated with the mobile terminal, a capability associated with the mobile terminal, a load situation in the second cell, or radio channel conditions associated with the mobile radio terminal.

摘要： A base station and method are described herein that vertically sweeps an antenna beam within a cell to improve the signal quality at scheduled times for a user terminal located within a coverage area of the cell. In one embodiment, the method improves a signal quality for a user terminal by: (a) vertically sweeping a beam within a cell coverage area to vary a signal quality at scheduled times for the user terminal located within the cell coverage area; and (b) performing one or more scheduling functions while taking into account variations in the vertical sweep of the antenna beam. For instance, the scheduling function(s) can include a link adaptation function, a resource allocation function, a user admittance/dropping function, a handover function, and/or a hybrid automatic repeat request function.

摘要： A signal power associated with a signal received in a current time period is determined. The determined signal power is combined with a predicted effective interference to form a predicted signal-to-interference indicator. The predicted signal-to-interference indicator is compared to a target signal-to-interference indicator. One or more transmit power control commands are generated based on the comparison. In one example embodiment, the predicted effective interference is based on an effective interference estimated for a previous time period. In another example embodiment, the predicted effective interference is based on interference contributions estimated in a current time period and a predicted interference cancellation efficiency. The predicted interference cancellation efficiency is based on the estimated interference cancellation efficiency for a previous time period. The technology is particularly useful in receivers that use interference cancellation and achieves excellent transmit power control performance both in terms of accuracy and speed.

摘要： A control node (26) of a radio access network (24) comprises a soft handover unit (62) and a power control unit (50). The soft handover unit (62) controls a soft handover procedure wherein a user equipment unit (30) has diversity in radio transmissions with plural radio base stations (28) comprising an active set of base stations. The power control unit (50), during the soft handover procedure, facilitates an adjustment of an uplink power level used by the user equipment unit (30) for uplink radio transmissions to the plural base stations by an adjustment amount. The adjustment amount is determined to promote uplink synchronization for all radio base stations of the active set. In one example embodiment, the power control unit (50) comprises a soft handover power boost function (70) which, during the soft handover procedure, increases the uplink power level used by the user equipment unit (30) for uplink radio transmissions by the adjustment amount. The adjustment amount is preferably a function of a difference between power levels of downlink reference signals of the active set.

摘要： An N-element rotational-symmetric array antenna can generate N fixed pencil-beams simultaneously with an omnidirectional beam. An N×N Butler matrix can be used to feed the array antenna, using fewer than N input ports of the Butler matrix to produce the pencil-beams. One or more of the modes generated by the Butler matrix can be individually accessed to produce one or more corresponding omnidirectional beams. The N×N Butler matrix can be driven by a feed network that provides both power dividing and beam-steering, which permits simultaneous generation of the N pencil-beams.

摘要： In a Time Division Multiple Access based radio telecommunications system that employs downlink power control, received signal strength information is measured and reported. A downlink data signal is transmitted from a base station to a mobile station during a first timeslot. A control channel signal or a dedicated traffic channel signal having equivalent output power behavior as the control channel, is transmitted from the base station throughout a cell in which the mobile station is operating. At the mobile station, a received signal strength of the control channel signal or the dedicated traffic channel signal is measured. The received signal strength may be measured in period between when the mobile station transmits and receives or in a period between when the mobile station received and transmits. The received signal strength may be measured during the first timeslot or during a timeslot other than said first timeslot. The received signal strength may also be measured during a time period associated with Mobile Assisted Handover (MAHO) measurements, the MAHO list including the control channel and/or the dedicated traffic channel. The received signal strength as measured by the mobile station is reported to the base station. The measured received signal strength is compensated for to obtain signal strength information associated with the downlink data signal received by the mobile station during the first timeslot.

摘要： The present invention is directed to cellular systems and methods for providing a multi-beam antenna configuration within a base station without utilizing duplex filters. The multi-beam antenna configuration of the present invention produces overlaid beams in both the uplink and downlink to cover the same area. Each beam has orthogonally oriented polarization directions (e.g., linear polarized slanted ±45°) for the uplink and downlink. Adjacent uplink beams shall also have shifted polarization directions in order to attain polarization diversity between different beams. In order to implement this polarization configuration, for each beam, there is a selective filter in front of the low noise amplifier for the uplink, and no duplex filter in front of the amplifier in the downlink direction.

摘要： A radiocommunication method and system which facilitates half-rate communications as well as downlink power control and selective beam transmission is described. Data associated with two terminals is multiplexed into a single timeslot. A first terminal's data occupies a first portion of the timeslot, while the second terminal's data occupies a second portion of the timeslot. A synchronization/training field may separate the first and second portions of the timeslot. In this way, a base station can change the power level and/or direction of transmission of the different terminal's data even though that data is multiplexed together on the same timeslot.
