Abstract:
The present invention relates to a method in a radio network node of a cellular network, for controlling admission of a UE in a cell covering a region. The method comprises obtaining (710) a location of the UE, comparing (720) information related to a geometric boundary of the region and the obtained location of the UE, and determining (730) whether to admit the UE in the cell based on the comparison.
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.

A method in a user equipment (140) for assisting a first radio network node (110) in selection of one or more mobility parameters, a method in the first radio network node (110) for selecting one or more mobility parameters and a user equipment (140) and a first radio network node (110) configured to perform the methods are provided. The user equipment (140) sends (C001) an indication of a second part of a first operating frequency band to the first radio network node (110). The first radio network node (110) selects (C004) said one or more mobility parameters based on the received indication of the second part of the first operating frequency band. The user equipment (140) receives (C005) and applies (C006) said one or more mobility parameters from the first radio network node (110).
Abstract:
The present invention relates to a method in a wireless device for improving wireless device performance, and to corresponding methods in a radio network node and to the corresponding nodes. The method comprises identifying (910) an occasion comprising a time period during which at least one time-frequency resource element, in a subframe that is transmitted between the wireless device and the radio network node, does not comprise information intended for the wireless device, or is not a time-frequency resource element in which the wireless device is expected to transmit. The method further comprises performing (920) an auxiliary action during the identified occasion to improve the wireless device performance.
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.
Abstract:
A method for configuring communication in a wireless communication system includes obtaining, at a first network node, information indicating a plurality of candidate subframes for downlink transmissions to a wireless communication device in a first cell served by the first network node. Each candidate subframe satisfies a candidate condition that relates to transmissions in a second cell during that subframe. The method also includes determining, based on the obtained information, a number of copies of an uplink transmission a wireless communication device should transmit in consecutive uplink subframes so that a downlink transmission related to the uplink transmission will occur during one of the candidate subframes. Additionally, the method includes configuring the wireless communication device to transmit the determined number of copies of the uplink transmission in consecutive subframes.

The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

Abstract:
A networks node generates an inter-frequency neighbor list of neighbor cells intended to be measured including neighbor cells satisfying an alignment condition and a sufficient measurement time. The alignment condition is satisfied when subframes of a first signal having a first frequency transmitted via a reference cell associated with the user equipment are synchronized with, have a known offset relative to or have a random offset smaller than one half of a sub frame relative to corresponding subframes of a second signal having a second frequency transmitted via a neighboring cells. The sufficient measurement time is determined by an overlap of measurement gaps and positioning subframes in the second signal. The user equipment performs the inter-frequency Reference Signal Time Difference (RSTD) measurements during measurement gaps.
