摘要： The present invention relates to a node in a wireless communication system, the node having a central point and comprising at least two antenna functions. Each antenna function is arranged to cover a corresponding sector area, the sector areas being positioned around the central point successively such that each sector area is adjacent to at least one other sector area separated by corresponding borders. The polarization of at least one of said antenna functions is variable between the borders of the corresponding sector area such that for each border, the polarizations of the antenna functions at each side of the border are essentially orthogonal at the border. The present invention also relates to a corresponding wireless communication system and corresponding antenna functions.

摘要： A transmitter (20) for a code division multiple access radio access network intelligently preconditions a channel-merged signal which is applied to its amplifier (22) so that the amplifier does not experience, e.g., precipitous power changes. The transmitter (20) comprises an amplifier (22) for amplifying the channel-merged signal at a signal output power; a detector (24) for performing detection of when output power of the channel-merged signal is about to change by a specified amount; and, a noise inserter (26) for adding a noise signal to the channel-merged signal in dependence upon the detection. Insertion of the noise smoothes an edge of the power change curve and thereby averts stress for the amplifier.

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： The present invention relates to handover procedures in a cellular communications system (1). The cells (10-70) of the system (1) are divided into multiple handover-related classes based on their respective radio coverage characteristics. Each such cell class is then associated with a unique handover parameter or a unique set of parameters that are used in handover procedures involving the cells (10-70). The parameter values are adapted for the radio coverage characteristics of each cell class in order to generate a suitable handover region size of the cells (10-70). The handover parameters are used together with user equipment-assisted signal quality measurements for triggering the handover procedures.

摘要： Methods and nodes in a cellular communication system for supporting Random Access. A method in a first network node involves determining at least one uplink radio resource amongst a plurality of radio resources, and refraining from scheduling uplink communication in the at least one uplink radio resource, thus enabling a UE in an area with an uplink/downlink imbalance to perform Random Access to a neighbor second network node (B).

摘要： Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, it is assumed that a mobile unit is served by an active cell set (S1). A basic idea according to the present invention is to select, prior to establishment of a new serving radio link for a mobile unit, a narrow target beam within a neighbor area of the current active cell set of the mobile unit based on pre-established information of narrow beams within the neighbor area (S2), and to initiate establishment of the new serving radio link directly with the selected narrow target beam (S3). In this way, the narrow target beam can be selected at handover initiation and the new radio link can be established directly with a target narrow beam without first establishing the radio link with a cell-wide beam and then, after uplink measurements, reconfiguring the radio link onto a narrow beam.

摘要： The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross-polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.
