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.
Abstract:
In its various aspects, the present invention addresses the many challenges associated with making timing measurements involving multifarious radio links. Such measurements are referred to herein as “enhanced” to connote that such timing determinations are being made across multifarious radio links. Here, a radio link will be understood as connecting two radio nodes, and two radio links are considered to be multifarious with respect to each other if they are opposite in terms of uplink and downlink transmit directions, and further if they are associated with different cell identifiers and/or if the two links are between different pairs of radio nodes. In this context, the teachings herein disclose the sharing of “enhanced timing measurement” capability information, e.g., between radio nodes and positioning nodes. Such information indicates the enhanced timing measurement capability of a radio node. Sharing such information enables another node, e.g., a positioning node, to determine an enhanced timing measurement configuration to be used by a radio node. Further, additional teachings herein disclose advantageous configurations for making enhanced timing measurements, and techniques for compensating timing measurements determined from multifarious radio links, e.g., compensating for frequency-dependent propagation time differences.
Abstract:
A user equipment for handling a cell change from a first cell to a second cell in a wireless communications network alters a duration of a measurement time over which at least one measurement is performed and alters a measurement bandwidth of the at least one measurement. The alterations may be performed based on associated bandwidths of the first and second cells. A network node sends, to the user equipment, a notification of a cell change and information associated with the cell change and also receives measurement data of at least one measurement performed over an altered measurement bandwidth and an altered duration of measurement time where the alterations are based on the information associated with the cell change.
Abstract:
The invention provides a method and a network node for controlling configuration of measurements to be performed by a user equipment (150a, 150b) operating in a wireless communication system (101). A configured measurement corresponds to at least one reporting criteria and the user equipment (150a, 150b) is able to support a limited number of parallel reporting criteria. Measurements to be performed by the user equipment in parallel may be requested by different network nodes such as a positioning server (140) and an eNodeB (110a, 110b). By letting a network node, such as the positioning server (140) or the (eNodeB 110a, 110b), obtain information on measurements requested by another network node the network node is able to configure the user equipment with a set of measurements that does not exceed at least one predetermined threshold for parallel reporting criteria.
Abstract:
In methods and devices GNSS reception quality can be used to determine the maximum output power of a Home UE, i.e. a UE served by home base station and is based on the insight that GNSS reception quality may be used for estimation of the interference caused by transmissions of an HUE on an existing network. The power of the HUE need be restricted to keep interference within limit. The estimation of the interference, and the determination of the HUE maximum output power, is based on the GNSS reception quality in the HUE, or the GNSS reception quality in the HBS or on a combination of the GNSS reception in the HUE and the HBS. In one embodiment a combined metric based on the GNSS reception quality and one or more cellular radio measurement is used to determine the maximum output power of the HUE. The GNSS reception quality measurements and the cellular measurements used for deriving the combined metric can be performed in the HUE and/or in the HBS or in both. Hereby a number of advantages over current systems and methods can be achieved. For example, the interference from the HUE (served by the home BS) to other cellular network e.g. macro network or relay nodes is reduced. The GNSS or A-GNSS receiver in the UE and/or home BS are exploited for setting an appropriate maximum output power of the HUE. The HUE served by the home BS is able to operate at its maximum possible output power level whenever possible without significantly generating interference towards the surrounding network.
