摘要： The invention presents methods and corresponding device relating to cooperative spectrum sensing. First a candidate set of sensors that can participate in an occasion of cooperative spectrum sensing is obtained. A cost formula for calculating a cost associated with using sensors from the candidate set in the cooperative spectrum sensing is then defined (75; 107, 97). The candidate set is partitioned (29; 14, 145) into an active set and a passive set. The active set contains any sensor (s) from the candidate that is to participate in the cooperative spectrum sensing. The passive set includes any sensor (s) that is not to participate in the cooperative spectrum sensing. The partitioning of the candidate set is done by applying an optimization procedure (79, 81, 83; 111, 113, 115) which performs a constrained optimization of the cost in accordance with the defined cost formula.

摘要： The invention comprises a method and a corresponding apparatus (53). A candidate set of sensors that are available to participate in an occasion of cooperative spectrum sensing is obtained. For each sensor in the candidate set, its radial distance to a central coordinating node in a communication system is also obtained (73). A sequence of minimum radii is produced (75,79). For each minimum radius in the sequence, an accommodation number is determined (75,87). The accommodation number associated with a minimum radius is the greatest number of sensors that can be placed on circle having this radius without a probability that all these sensors are mutually uncorrelated falling below a design probability threshold. Sensors from the candidate set are then selectively added (91,95) to an active set of sensors based on the minimum radii, the corresponding accommodation numbers and the obtained radial distances.

摘要： Mobility-based radio resource assignment methods, systems and devices can assign user equipment to different nonoverlapping groups of radio resources depending on mobility of the user equipment. The groups of radio resources are nonoverlapping in time, frequency and/or code. For example, the groups of radio resources can include different pilot symbol densities, link adaptation and/or scheduling algorithms. The radio resources may be Long Term Evolution (LTE) radio resources.

摘要： This document discloses solutions for using a mix of reference signal types in a wireless communications network, e.g., a first type and a second type, in making positioning-related measurements. In one example, a UE uses a “mix” of CRS and PRS. As an example case, a UE receives PRS and, possibly, CRS from one or more cells, while it receives only CRS from one or more other cells. In this case, the UE determines, e.g., received signal timing values for CRS as received from some cells, on a per-cell basis, and for PRS as received from other cells, on a per-cell basis. The UE can measure and report on per-signal/per-cell basis and can perform calculations involving a mix of timing measurements made for both CRS and PRS. In a further aspect, reference signal transmissions are controlled or coordinated on a per-port basis in cells that use multiple antenna ports for transmitting within each such cell.

摘要： The present invention relates to a method and a secondary user enabling secondary usage of radio resources owned by a primary party. The present invention also relates to a primary party and a broker. The secondary user is adapted to obtain radio resource allocation information transmitted from the primary party. It is further adapted to identify radio resources available for secondary usage based upon the radio resource allocation information. It is finally adapted to engage in communication over at least part of the radio resources identified as available for secondary usage.

摘要： The invention presents methods and corresponding devices for improving cooperative spectrum initiating sensing. A device (61;61.1) first receives an invitation (17;35) to participate in cooperative spectrum sensing. The device performs an autonomous decision (19) on whether or not to participate in the cooperative spectrum sensing in response to the invitation. If it is determined to participate in the cooperative spectrum sensing to which the invitation relates, spectrum sensing is then performed (21;45). With the invention, sensor selection becomes “distributed”, i.e. it is up to the device itself to decide on participation in the cooperative sensing, rather than having, for example, a central entity determining what devices should act as sensors in the cooperative spectrum sensing. One advantage is that the amount of signalling required for sensor selection can be kept at a minimum, thereby saving communication resources.
