摘要： A network node is connected to a plurality of antenna nodes that are located along a path where a plurality of wireless communication devices are located. The antenna nodes are controlled (302) to maintain reception radio lobes substantially along the path such that the wireless communication devices can communicate with the network node via the reception radio lobes. From a detected (304) radio frequency signal, a determination (306) is made that a UE belongs to a group of UEs having common Doppler radio frequency characteristics. This determination then enables processing (308) of the received signal involving the common Doppler characteristics.

摘要： In one aspect of the teachings herein, network-side and device-side methods and apparatus identify a subset of frequency layers on which a wireless device performs regular inter-frequency scanning. The subset is identified from among a set of frequency layers that are candidates for inter-frequency measurement by the device. In an example, the wireless device scans the set of frequency layers and the corresponding scan results are used to select the best frequency layers in the set. In turn, the wireless device performs regular inter-frequency measurements on the frequency layers in the selected subset. Scanning thus can be understood as a mechanism for intelligently selecting preferred ones among a number of frequency layers that are candidates for inter-frequency measurement by the device.

摘要： In one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the measurement rate to use for making inter-frequency measurements on a given frequency layer, based on a performance requirement specified for that layer. For example, the wireless device uses a higher measurement rate for a frequency layer that has a performance requirement that is higher than the performance requirement specified for another one of the layers on which it is to perform inter-frequency measurements. Correspondingly, in an example scenario, a network node sends measurement configuration information to a targeted device, where that information indicates the layers on which the device is to perform inter-frequency measurements and indicates the performance requirements corresponding to respective ones of those layers. By way of example, the network node may be a base station, a relay, or another wireless device.

摘要： A method performed by a network node for determining a mobility criterion related to a wireless communications device in a wireless communications network. The network node obtains an information related to an UL propagation condition associated to the wireless communications device. The network node determines a measure of imbalance between the UL propagation condition and a DL propagation condition associated to the wireless communications device. The measure of imbalance is based on the information related to the UL propagation condition. The network node determines the mobility criterion based on the measure of imbalance between the UL propagation condition and the DL propagation condition.

摘要： Antenna nodes are controlled to maintain a respective radio cell, each cell having one and the same physical cell identity. The antenna nodes are further controlled to maintain the respective radio cell in a single direction substantially along a path such that each wireless communication device, during movement in a movement direction along the path, can connect either to consecutive antenna nodes towards which the wireless communication device is moving or connect to consecutive antenna nodes away from which the wireless communication device is moving.

摘要： Techniques for configuring and using measurement gap patterns for offloading purposes are disclosed. An example method, performed in a network node of a wireless communication network, includes selecting (410) a measurement gap pattern to be used by the mobile terminal, the measurement gap pattern having a series of measurement gap bursts such that the measurement gap bursts are separated by a repetition period and each measurement gap burst comprises two or more measurement gaps, and signaling (420) the measurement gap pattern to the mobile terminal. In some embodiments, the repetition period is chosen so that the measurement gap pattern repetition period and the long-DRX cycle length in some embodiments are related to each other by an integer power of N.
