摘要： A method and controlling node ( 400) of a cellular network, to control measurements on signals to or from a User Equipment, UE, engaged in a radio communication in a cluster cell served by multiple transmission points (404). A set of conditions potentially affecting performance for the UE in the cluster cell, is identified. At least one type of reference signals and corresponding radio measurement(s) are then selected based on the identified set of conditions. The controlling node obtains measurements made on the selected type(s) of reference signals according to the radio measurement(s), and configures a UE-specific measurement set of transmission points (406) for the UE, out of the transmission points (404) serving the cluster cell, based on the obtained measurements. The UE is then instructed to perform and report measurements on UE-specific downlink signals transmitted from the transmission points of the UE-specific measurement set.

摘要： Parameters that define the frequency raster points to be used in an unlicensed band are used to support operation of wireless devices in both licensed and unlicensed frequency bands. Corresponding signaling messages are used to exchange information regarding the device's capabilities, preferences, transmission power, etc. In one method, implemented in a wireless communication device (410) configured to operate in at least first and second frequency bands, a radio access network is accessed (510), using a first radio access mode and the first frequency band. The method further comprises transmitting (520) frequency raster data to the radio access network, wherein the frequency raster data corresponds to the second band, indicates a tuning capability of the wireless communication device (410), and comprises at least a first frequency index and a granularity indicator. Methods and apparatus for maintaining a database of access point capabilities in unlicensed bands are also disclosed.

摘要： Method and arrangement in a serving base station for determining a binary value of information data received from a user equipment, by using a supportive likelihood value received from a supporting base station. The user equipment transmits information data to be received both by the serving base station and the supporting base station. The method comprises: decoding information data bits received from the user equipment into a first likelihood value, without determining a binary value for each bit of the information data, a supportive likelihood value of the information data bits transmitted from the user equipment is received from the supporting base station, which supportive likelihood value is based on a decoding of the information data bits performed in the supporting base station. The first likelihood value of the decoded information bits is combined with the received supportive likelihood value of the decoded information bits. Thus a binary value for each bit of the information data transmitted from the user equipment is determined, based on the combined first and supportive likelihood values.

摘要： The present disclosure relates to a method and a network node 100 in a wireless communications network 1. In particular, it relates to selecting a frequency band for operation for user equipment 9 in the wireless communications network 1. The frequency band to be selected is either a licensed frequency band or an unlicensed frequency band. The network node 100 is a macro base station 5, or a home base station (7, 700), and is adapted to communicate with user equipments 9 in the wireless communications network 1 which comprises both the macro base station 5 and the home base station (7, 700). The home base station (7, 700) is adapted to support operation in both the licensed frequency band and the unlicensed frequency band. The method comprises obtaining radio condition measurements performed on the licensed frequency band and/or on the unlicensed frequency band; selecting the frequency band, based on the obtained radio condition measurements; and updating the home base station of the selected frequency band to be used for communication with one or more of the user equipments.

摘要： A wireless communication system (14) comprises points that have time division duplex, TDD, configurations. Information is obtained indicating the TDD configuration of each of multiple points to which a particular wireless communication device (6) is simultaneously connected. Based on this obtained information, it is determined that one or more time-domain radio resources used by the multiple points are conflicting resources defined by the TDD configuration of one or more of the multiple points as being uplink resources and defined by the TDD configuration of one or more others of the multiple points as being downlink resources. For the device (6), each of the one or more conflicting resources are resolved as either an uplink resource to be used by the device (6), a downlink resource to be used by the device (6), or a resource not to be used by the device (6), based on one or more rules for optimizing use of conflicting resources.

摘要： Error vector magnitude (EVM) is pooled and adaptively distributed among carriers in a multi-standard or multi-carrier system to reduce peak to average power ratios (PAPR) without exceeding EVM limits. Correction tone injection is used to reduce PAPR. The amplitude of each correction tone, and number of correction tones assigned to a carrier, are adjusted to control the EVM and out-of-band distortion of each carrier, to comply with EVM limits imposed by the respective radio access technology.

摘要： A method in a UE for adapting a radio procedure is provided. The UE obtains (502) information about signal configurations indicating: -whether or not a DL RS, transmitted in cells on a first carrier frequency of a first carrier use the same one of a first and a second signal configuration, or - whether or not the DL RS transmitted in the cells on the first carrier frequency use the same one of the first and the second signal configuration as that used for DL RS transmitted in a serving cell of the UE on the first carrier frequency. The first signal configuration comprises the DL RS not being transmitted in every subframe. The second signal configuration comprises the DL RS being transmitted in every subframe and also in every resource block over an entire channel bandwidth of a neighbour cell. The UE adapts (503) a radio procedure based on the information.

摘要： The present invention uses user-specific resources, as allocated on the uplink, for conveying one or more antenna-specific sounding reference signals (SRSs). This technique advantageously permits, for example, a user equipment (UE) configured for uplink Multiple- Input-Multiple-Output (MIMO) operation to send antenna-specific SRSs within the granted resources allocated to the UE via one or more scheduled uplink grants. That is, within the granted resources allocated by a given uplink grant, a UE uses at least a portion of those resources for sending antenna-specific SRSs, rather than for sending uplink data (user traffic). Thus, in one or more embodiments, the present invention comprises a method at a UE of transmitting antenna-specific SRSs for two or more uplink transmit antennas. The method comprises transmitting an antenna-specific sounding reference signal for at least one of the uplink transmit antennas within a granted resource allocated to the user equipment for a scheduled uplink data transmission.
