摘要： The present invention relates to an antenna arrangement (3) for use in a wireless communication system (1), where the arrangement (3) comprises at least two single-polarized antenna functions (4, 5). Each antenna function (4, 5) is adapted for radiating an antenna radiation lobe pattern (6) having a horizontal extension in an azimuth plane (A), and a vertical extension in an elevation plane (E), perpendicular to the azimuth plane (A). The antenna functions (4, 5) both have essentially a first polarization in a first direction (11). In a second direction (15) separated from the first direction (11), the second antenna function (5) has a second polarization and the first antenna function (4) has a third polarization, the second polarization and the third polarization being essentially orthogonal to each other.

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： Methods and arrangements in a data transmitting node, a data receiving node and an intermediate node, where one of the data transmitting node and the data receiving node is a mobile terminal and the other nodes are access points. The methods and arrangements involve that ACK and NACK feedback are transmitted on different respective paths, according to different criteria, when the mobile terminal is simultaneously associated with more than one access point.

摘要： The present invention relates to a node (1) in a wireless communication system (2), the node (1) having a central point (3) and comprising at least two antenna functions (4, 5, 6). Each antenna function (4, 5, 6) is arranged to cover a corresponding sector area (7, 8, 9), the sector areas (7, 8, 9) being positioned around the central point (3) successively such that each sector area (7, 8, 9) is adjacent to at least one other sector area separated by corresponding borders (10, 11, 12). The polarization of at least one of said antenna functions (4, 5, 6) is variable between the borders (10, 11, 12) of the corresponding sector area (7, 8, 9) such that for each border (10, 11, 12), the polarizations of the antenna functions (4, 5, 6) at each side of the border (10, 11, 12) are essentially orthogonal at the border (10, 11, 12). The present invention also relates to a corresponding wireless communication system and corresponding antenna functions.

摘要： The present invention is directed to cellular systems and methods for providing a multi-beam antenna configuration (50) within a base station without utilizing duplex filters. The multi-beam antenna configuration (50) of the present invention produces overlaid beams (1, 2, 3, 4) in both the uplink and downlink to cover the same area. Each beam (1, 2, 3, 4) has orthogonally oriented polarization directions (e.g., linear polarized slanted +45E) for the uplink and downlink. Adjacent uplink beams (1, 2, 3, 4) shall also have shifted polarization directions in order to attain polarization diversity between different beams (1, 2, 3, 4). In order to implement this polarization configuration, for each beam (1, 2, 3, 4), there is a selective filter (60) in front of the low noise amplifier (40a) for the uplink, and no duplex filter in front of the amplifier (40b) in the downlink direction.

摘要： The disclosure describes a novel Time Difference of Arrival (TDOA) method (500) and system (100, 600 and 700) for determining the position of a first mobile radio terminal (108) within an associated mobile radio system (100, 600 and 700), which is based on Time of Arrival (TOA) measurements, including a plurality of radio base stations (BS1, BS2, BS3), measuring devices (130), network controller (110), and service node (103). The measuring devices are synchronized in otherwise unsynchronized radio base stations (BS1, BS2, BS3). The measuring devices (130) measure TOA on demand and (optionally) Direction of Arrival (DOA), on a digital uplink time slot (301 and 302) or on digital information on an analog uplink traffic channel in one or more radio base stations (BS1, BS2 and BS3). The TOA and DOA information and the traffic channel number are reported to a Mobile Services Switching Center (102), which obtains the first mobile terminal's (108) identity from the traffic channel number and sends the terminal identity and TOA and DOA measurement information to a Service Node (103). The Service Node (103) calculates the position of the first mobile radio terminal (108) using the TOA information (supplemented by the DOA information when available). A second mobile radio terminal (601) is colocated on a mobile platform (auto, emergency vehicle, etc.) with one of the radio base stations (BS1, BS2 or BS3), which can be moved into relatively close proximity with the first mobile radio terminal (103). Consequently, by moving one of the radio base stations (BS1, BS2 or BS3) close to the region of interest (near the first mobile radio terminal (108)), the position determination accuracy is significantly improved.

摘要： Directional-beam generative apparatus (62), and an associated method (102) for a radio communication station (36) forms directional antenna beam patterns (22, 34, 36, 52, 54, 56) for the communication of communication signals with remote communication stations (24, 26, 28) operable in a TDMA communication system (10). Channels (12, f1) are allocated for effectuation of communications between the radio communication station (18) and the remote stations (24, 26, 28) responsive to indications of locations at which the remote communication stations (24, 26, 28) are indicated to be positioned. Remote communication stations indicated to be positioned within a selected area are allocated to channels (12, f1) formed upon a single carrier (f1).
