  • Publication number: 20220295413
    Abstract: Systems, methods, apparatuses, and computer program products for panel specific uplink power control. A method may include receiving, at a user equipment, an uplink grant indicating an uplink candidate beam for uplink transmission; receiving, at the user equipment, a plurality of power control configurations, wherein one of a plurality of sources of spatial relation information is associated with one of the plurality of power control configurations; determining, at the user equipment, a power control configuration of the plurality of power control configurations for the indicated uplink candidate beam based on an association between a source of spatial relation information and the power control configuration; and transmitting, from the user equipment, uplink data using the indicated uplink candidate beam and the determined power control configuration.

  • Patent number: 10484983
    Abstract: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

  • Publication number: 20130188530
    Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring/implementing by a network/network element a partial full-duplex in time dependent operational mode for wireless communications between UEs and the network/network element, e.g., in LTE systems. The time dependent partial full-duplex may further include bandwidth allocations for the full-duplex and half-duplex time intervals. In the half-duplex time periods, undesirable interference and self-interference effects during signal detection by the UEs and/or eNBs may be reduced to an advantage.

  • Publication number: 20130188536
    Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring/implementing full-duplex communications between UEs and a network on a partial frequency domain in wireless communications, e.g., in LTE systems. This may allow UEs with different transmission capabilities to operate on the same deployment bandwidth and to use time dependence of an operational mode. According to an embodiment, a network element, such as eNB, may configure a deployment bandwidth in a frequency domain for wireless communications between UEs and the network, wherein one or more full-duplex regions of the deployment bandwidth are allocated for full-duplex communications and one or more half-duplex regions of the deployment bandwidth are allocated for half-duplex communications.

  • Patent number: 8155252
    Abstract: A frequency error correction scheme applicable in a receiver of a mobile telecommunication system is presented. The present frequency error correction scheme is carried out in a time domain after an equalization process. The present frequency error correction scheme may be applied to a base station receiving signals transmitted according to a single-carrier frequency division multiple access communication scheme. The separation of different received signals for further processing is carried out in the frequency domain before the equalization and the frequency error correction.

  • Patent number: 8081717
    Abstract: An apparatus includes a radio frequency receiver and a timing adjustment unit that contains at least two channel impulse response estimators. The at least two channel impulse response estimators include an on-time estimator and at least one of an early estimator and a late estimator. The apparatus also includes a calculation unit that is configurable to obtain a channel estimate for each measured channel impulse response and to average obtained channel estimates over a plurality of received signal events to determine a timing adjustment in accordance with residual signal power.
