摘要： The present invention relates to a method and a communication network node for enabling automatic planning and handling of root sequences used at random access in a communication network system, wherein user equipments (18) are accessing a cell (19a) being served by said communication network node. Root sequence usage information from neighbouring cells (19b, 19c) is acquired. Root sequence conflicts between root sequences used in said served cell (19a) and root sequences used in said neighbouring cells (19b, 19c) are detected. When no conflict is detected, appropriate new root sequence(s) is/are selected. Otherwise, detected root sequence conflicts are resolved by deriving a new set of root sequences.

摘要： A method in a base station (110) for enabling the base station (110) to identify a neighbouring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighbouring base station (120). In response to reception of the sent identification requesting message, a neighbouring base station identifier that is associated with and identifies the neighbouring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighbouring base station (120). By receipt of the neighbouring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighbouring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighbouring base station to perform handover measurements with regard to the same or another user equipment.

摘要： The present invention relates to a method and a communication network node for automatically tuning a PRACH configuration parameter in a communication network system comprising radio base stations each serving at least one cell and with which user equipments are communicating on uplink and downlink channels. The PRACH configuration parameter is used for defining the division of uplink resource blocks between PRACH and PUSCH. Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter.

摘要： The present invention relates to an arrangement, a communication network node and a user equipment allowing for probing of alternative antenna configurations in a communication network system as well as a method for such probing. The method comprises making one of the reconfigurable antennas (15a2, 15b2) of at least one cell (19a, 19b) temporarily available for probing and reconfiguring one or more antenna parameters thereof in accordance with a probing antenna parameter set. A new probe cell (20a, 20b) is transmitted from the prepared antenna (15a2, 15b2) and measurement reports collected from the user equipments (18) within the at least one cell (19a, 19b) and the probe cell (20a, 20b). The probing antenna parameter set is evaluated based on the collected measurement reports whereupon is determined if the reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) of the cell shall use the probing antenna parameter set or the initial antenna parameter set. Finally the probing cell (20a, 20b) is removed and the antennas (15a1, 15a2, 15b1, 15b2) adjusted in accordance with the determination.

摘要： In one of its aspects the technology concerns a method of operating a telecommunications system (10) comprising a serving radio base station (50 S ) and a candidate radio base station (50 C ). The serving radio base station (50 S ) comprises a radio base station to which a wireless mobile station (30) provides measurement reports. The serving radio base station (50 S ) and the candidate radio base station (50 C ) are different with respect to at least one of frequency and radio access technology. The method comprises the serving radio base station (50 S ) allowing the mobile station (30) to obtain information broadcasted by the candidate radio base station (50 C ). The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station (50 C ) or the Cell Global Identity (CGI) itself of the radio base station. The mobile station (30) obtains the information from the candidate radio base station (50 C ) during at least one reading gap. The reading gap is a time period in which the mobile station (30) does not receive information from the serving radio base station (50 S ).
