  • Patent number: 11903007
    Abstract: A transmitter in a frequency domain duplexing (FDD) network system is configured to receive spectral information from neighbor receiver nodes. For each of the neighbor receiver nodes, the transmitter computes an SNR at each of the plurality of frequencies, forming an SNR curve. For each of the transmit frequencies, the transmitter identifies minimum SNR values among the SNR values on the SNR curves. The minimum SNR values form a composite minimum curve. Based on the composite minimum curve, the transmitter determines whether an SNR of a current transmit frequency is above (1) a first threshold associated with an operating SNR, or (2) a second threshold associated with a maximum of the composite minimum curve. Based on the determination, the transmitter determines whether a new transmit frequency is selected to replace the current transmit frequency.

  • Patent number: 11071028
    Abstract: Access nodes in a network are configured to periodically measure cell loads and exchange cell load measurements with neighbors. At each access node, cell loads are compared with load thresholds, and with neighboring loads, to determine whether or not load balancing operations should be triggered. Load balancing operations include reducing or increasing an effective coverage area of one or both of the congested cell and the neighbor cell by adjusting a handover threshold parameter, such as a threshold signal level. Adjusting thresholds at a congested cell triggers more handovers from the congested cell to the non-congested cell. Similarly, adjusting thresholds at a non-congested cell prevents handovers from the non-congested cell to the congested cell.

  • Patent number: 10021693
    Abstract: A base station will determine both that a served device's power headroom is threshold low and that the device's downlink receive signal strength is threshold low. In response to at least determining both that the device's power headroom is threshold low and that the device's downlink receive signal strength is threshold low, the base station will then begin applying an uplink coverage boosting process for the device, including limiting or reducing the number of frequency blocks that the base station allocates to the device for uplink transmission per transmission time interval, to help increase the device's per-frequency-block transmission power and thus the device's uplink communication quality. This could be usefully carried out with respect to voice over Long Term Evolution (VoLTE) uplink coverage boosting (VUCB) for instance, to help improve voice communication quality.

  • Patent number: 9992719
    Abstract: There is provided a method, performed by a network node (e.g. an RNC), for detecting a neighbor cell relation between different radio access technologies in a cellular communication network. The method comprises the step (S1) of triggering a User Equipment, UE, served in a first cell of a first radio access technology (e.g. WCDMA cell) under the control of the network node (e.g. RNC), to perform a cell selection process by initiating a connection release with redirection to a second radio access technology (e.g. GSM), causing the UE to select a second cell of the second radio access technology (e.g. GSM cell). The method also comprises the step (S2) of receiving information representing the identity of the second cell selected by the UE (e.g. CGI), and the step (S3) of identifying, based on the received information representing the identity of the second cell and information representing the identity of the first cell, a neighbor cell relation between the first cell and the second cell.
