  • Patent number: 10966122
    Abstract: A method and a migration managing module for managing a migration of a service. The migration managing module determines a point in time relating to completion of the migration of the service based on resource requirements related to the service. For each radio network node a respective impact on a quality of the service is estimated. Moreover, the migration managing module selects from among servers at least one respective target server for which the respective server location measure of said at least one respective target server matches the respective radio network node location measure of said each radio network node, thereby obtaining a set of target servers comprising said at least one respective target server for said each radio network node. For each target server, a respective cost of the migration based on the resource requirements related to the service is determined. A respective tendency as a function of said each probability value, the respective cost and the respective impact is determined.

  • Patent number: 10904781
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.

  • Patent number: 10897289
    Abstract: A signal transmission method includes: processing, by a base station, a first baseband signal, a second baseband signal, a third baseband signal, and a fourth baseband signal by using a VAM matrix, to obtain four processed signals; performing precoding processing on the four processed signals to obtain four coded signals; and sending the four coded signals to a mobile terminal by using four radio frequency ports. The four radio frequency ports are in a one-to-one correspondence with the four coded signals. A first processed signal is the same as a third processed signal, a second processed signal is the same as a fourth processed signal. The first processed signal is obtained by performing superposition on the first baseband signal and the third baseband signal, and the second processed signal is obtained by performing superposition on the second baseband signal and the fourth baseband signal.

  • Patent number: 10880919
    Abstract: The embodiment of the present application relates to the field of wireless communication technology, and more particularly to a method and a device for configuring and determining semi-persistent scheduling, for solving the problems of resource waste and increased overhead caused by the use of an LTE SPS mode in a V2X communication mode in the prior art. According to the embodiment of the present application, a network side device utilizes the PDCCH signaling scrambled by the SPS C-RNTI, sends the SPS period and/or the SPS frequency domain resource configuration information corresponding to multiple sets of SPS configurations to a terminal. Due to the fact that multiple sets of SPS configurations can be configured to a terminal through the PDCCH signaling, the number of SPS configurations is increased as compared with the background technology in which only one set of SPS configuration can be configured, thereby reducing resource waste and overhead; and the system performance is further improved.

  • Patent number: 10834665
    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless systems may benefit from estimation of location of a user equipment (UE) within the system. Such estimations may be based at least in part on pilot signals received from one or more reference points (e.g., base stations, access points, etc.). However, in some cases, the communication range of the pilot signals may be too small to support location estimation for at least some UEs in the system. Further, the pilot signals may consume time-frequency resources, which may reduce throughput for the system. In accordance with the described techniques, highly detectable pilot signals may coexist with synchronization signal (SS) block transmissions. Such coexistence may improve accuracy of location estimations for some, or all UEs in the system, or otherwise benefit the system.
