  • Patent number: 10893531
    Abstract: Aspects and embodiments provide a method of allocating frame resource elements in a wireless communication network for the purpose of channel estimation, and a base station and computer program product operable to perform that method. One aspect provides a method of allocating resource elements in a wireless communication network. The method comprises: determining a channel estimate associated with each user equipment to be scheduled in a given frame; assessing whether a validity time associated with each channel estimation value, e.g. CSI, associated to each user equipment is still valid or should be considered as expired; and allocating the frame resource elements to either channel estimation, when the current channel estimation is not anymore valid, or else to data transmission, when it is still valid.

  • Patent number: 9894530
    Abstract: Methods and network nodes of a wireless telecommunications system are disclosed. One method of controlling transmissions with a base station of a wireless telecommunications system comprises the steps of: determining a set of neighboring base stations, each base station in the set of neighboring base stations utilizing an identical carrier and scrambling code to support transmissions with that base station; and allocating base stations in the set of neighboring base stations different spreading codes for transmissions with those base stations. By allocating each base station in the set of base stations sharing the same carrier and scrambling code different spreading codes, interference in transmissions between the base stations can be controlled.

  • Patent number: 9866301
    Abstract: In certain embodiments, a macrocell base station (BS), such as an LSAS BS, estimates its backhaul channels with a small-cell BS (e.g., a relay or repeater) by averaging multiple instances of a received pilot signal repeatedly transmitted by the small-cell BS. Since the macrocell and small-cell BSs are stationary, averaging the received pilot signal transmissions over time results in the zero-temporal-mean time-dependent component of each backhaul channel as well as zero-temporal-mean noise and interference signals from other wireless nodes to substantially cancel out, enabling the macrocell BS to relatively infrequently estimate a relatively time-invariant, dominant component for each backhaul channel. The macrocell BS uses the estimated dominant components to generate user-data-based downlink transmissions to the small-cell BS. In this way, the processing to estimate channel state information (CSI) data for the backhaul channels is greatly reduced compared to conventional techniques.

  • Patent number: 9629096
    Abstract: A method of communicating in a picocell within a macrocell includes automatically setting an uplink transmit power of a mobile station to avoid uplink interference between the picocell and the macrocell. A disclosed example includes determining an allowable interference from the picocell to the macrocell. A path-loss between a mobile station and a macrocell is determined. An uplink transmit power of the mobile station for communicating in the picocell is determined based upon the determined allowable interference and the determined path-loss.
