Abstract: A MIMO-capable base station allocates a maximum transmission power budget to each of its antennas. For serving each of one or more MIMO and non-MIMO users, one or more carriers are allocated. For each carrier, information about an amount of allocated MIMO and non-MIMO user resources associated with the carrier is used to derive coefficients. Each coefficient corresponds to a unique one of the antennas, and represents a proportion of a maximum power budget for the carrier. For each carrier, the coefficients and the maximum transmission power budget for the carrier are used to derive a maximum transmission power budget for each of the antennas. For each antenna, a total maximum transmission power budget for the antenna is derived by combining the derived maximum transmission power budgets of the carriers transmitted on the antenna. The total maximum power budget of the antenna should not exceed a limit for the antenna.

Abstract: Processing implemented by a method and apparatus herein advantageously improves the quality of measurements performed by a wireless device (36), by ensuring that the device (36) measures its serving cell over at least as large of a bandwidth as the bandwidth over which it measures neighbor cells. Such processing specifically includes identifying, for each of a plurality of neighbor cells, a measurement bandwidth over which the wireless device (36) is to perform measurements of that cell. Processing then entails selectively initiating handover of the wireless device (36) from a serving cell to one of the neighbor cells, depending on how many of those neighbor cells have a measurement bandwidth larger than that of the serving cell. Thus, contrasted with traditional performance-based handovers that are conducted based on the strength of already made reference signal measurements, handover herein is performed based on the bandwidth(s) over which such measurements will be performed in the future.

Abstract: A user equipment (UE) performs measurements on a serving cell and at least one neighbor cell in a heterogeneous wireless communications network that includes one or more higher power radio network nodes operating near one or more lower power radio network nodes. The UE acquires enhanced neighbor cell information (eNCI) including at least subframe information and determines an allowed set of one or more subframes during which the UE may make downlink and/or uplink measurements for at least one cell in the heterogeneous network. A network node in the heterogeneous network generates the eNCI, from which the UE may determine the allowed set of radio transmission subframes, and provides the eNCI for the UE to coordinate the UE measurements on the at least one cell during one or more of the allowed subframes.

Abstract: The disclosure relates to methods and arrangements wherein a user equipment (UE) supporting a first frequency band HB is enabled to communicate with a network utilizing a second frequency band. The second frequency band is a sub-band of the first frequency band or overlaps with the first frequency band. The UE, which supports the first frequency band, implements 32 the channel numbering scheme of the second frequency band SB which overlaps with the first frequency band HB. This enables the UE supporting the first frequency band HB to recognize the second frequency band SB and communicate 33 with the network when the UE is camped or connected to a cell operating in the second frequency band SB.
