  • Clustered periodic gaps for measurements in a heterogeneous network
    Patent number: 11234234
    Abstract: Techniques for configuring and using measurement gap patterns for offloading purposes are disclosed. An example method, performed in a network node of a wireless communication network, includes selecting (410) a measurement gap pattern to be used by the mobile terminal, the measurement gap pattern having a series of measurement gap bursts such that the measurement gap bursts are separated by a repetition period and each measurement gap burst comprises two or more measurement gaps, and signaling (420) the measurement gap pattern to the mobile terminal. In some embodiments, the repetition period is chosen so that the measurement gap pattern repetition period and the long-DRX cycle length in some embodiments are related to each other by an integer power of N.

  • METHOD AND SYSTEM FOR MANAGING INTERFERENCE IN MULTI TRP SYSTEMS
    Publication number: 20210409090
    Abstract: Systems and methods for managing interference in a communication network include transmitting a first downlink signal (50) from a first transmit/receive point (TRP) (46) to an electronic device (14) using a beam (62). The electronic device (14) can also receive a second downlink signal (52) from a second TRP (48), where a portion (54) of the first downlink signal (50) from the first TRP (46) interferes with the second downlink signal (52). The first TRP (46) then receives a series of uplink pilot signals (66, 68) from the electronic device (14). Using the received uplink pilot signals (66, 68), the first TRP (46) can then estimate the angle of departure (AoD) for the intended signal (first downlink signal (50)), and the AoD for the interference signal (54).

  • OPTIMIZING USAGE OF A COORDINATED SERVICE
    Publication number: 20200396706
    Abstract: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.
