  • Patent number: 11950157
    Abstract: Methods, nodes and computer program products control radio channel deployment when using un-licensed carriers in a wireless communication network and control mobility and/or load balancing target selection when using un-licensed carriers. When performed in an access node, unlicensed carrier intrinsic cell channel load is determined in a cell served by the access node based on one or more predetermined channel load indicators and neighbor cell channel load information is obtained, from one or more neighboring access nodes. The neighbor cell channel load information includes unlicensed carrier channel load in respective cells based on the one or more predetermined channel load indicators. At least one channel deployment operation is initiated based on an outcome of one or more comparative operations including the determined unlicensed carrier intrinsic cell channel load and/or the obtained neighbor cell channel load information.

  • Publication number: 20240089983
    Abstract: Systems and methods are disclosed for control of configured transmissions in a cellular communications system. A method performed by a wireless communication device includes receiving, from a base station, a configuration of a set of symbols for one or more configured transmissions and monitoring for a Downlink Control Information (DCI) that uses a particular DCI format. The method further includes, when the wireless communication device does not detect a DCI that uses the particular DCI format and either: (a) a semi-static Time Division Duplexing (TDD) configuration received by the wireless communication device indicates the set of symbols configured for the one or more configured transmissions as flexible or (b) the wireless communication device did not receive a semi-static TDD configuration, making a determination of whether the one or more configured transmissions are allowed to be transmitted or are received based on whether a parameter is configured.

  • Publication number: 20240064669
    Abstract: Embodiments include methods implemented in a wireless device for reporting of a cell global identifier (CGI) in a wireless network. In one embodiment, a method comprises receiving a synchronization signal/physical broadcast channel (SS/PBCH) block from a network node; locating a control resource set (CORESET) configured by the network node through determining a frequency position of the CORESET based on a value received from the network node through radio resource control signaling; and determining and reporting the CGI to the network node based on the located CORESET. In another embodiment, the CORESET is located through testing a set of one or more reference frequency candidates from which a frequency position of the CORESET is determined.

  • Patent number: 11901926
    Abstract: The gain of an amplifier in a receiver operating in a cellular communication system is controlled by determining one or more gain variability metrics, which are then used to produce first and second threshold values. A frequency difference between a current carrier frequency and a target carrier frequency is ascertained and then compared to the threshold values. Target gain setting production is based on comparison results: If the frequency difference is larger than the first threshold, a first automatic gain control algorithm is performed; if the frequency difference is smaller than the first threshold and larger than the second threshold, a second automatic gain control algorithm is performed, wherein the second automatic gain control algorithm uses a current gain setting as a starting point; and if the frequency difference is smaller than both the first and second thresholds, the current gain setting is used as the target gain setting.

  • Publication number: 20230328775
    Abstract: Systems and methods for changing Listen Before Talk (LBT) for unlicensed networks are provided. In some embodiments, a method performed by a wireless device includes: receiving signaling from a base station that indicates when the wireless device uses LBT for transmissions; determining, based on the received signaling, whether or not to use LBT for transmissions; and transmitting based on the determination whether or not to use LBT for transmissions. Some embodiments provide a low complexity (in term of signaling overhead and specification impact) approach of adaptively using LBT mechanism by defining two simple modes for LBT operation (LBT and No LBT modes). Some embodiments reduce the probability of simultaneous transmissions that cause collisions, by using LBT mode, in environments and circumstances where network performance suffers from collision and/or interferences.
