  • Patent number: 10772058
    Abstract: The present invention provides a muting configuration for reference signal (RS) transmission as a pattern defined by at least the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell thus are differentiated from another cell by use of a different muting sequence, a different reference point, or both. Moreover, in one or more embodiments, the present invention provides for the use of a common muting sequence or reference point across cells, with muting occasions being differentiated between cells through use of different reference points (in the case of a common muting sequence), or through use of different muting sequences (in the case of a common reference point), or different sequences and different reference points.

  • Patent number: 10715265
    Abstract: There are provided methods, apparatuses, and computer programs for improving measurement of a reference signal parameter measured by a wireless device, the reference signal parameter being a parameter of a reference signal transmitted by a radio network node in a wireless communication network. An example method includes determining that the wireless device is operating with a low measurement accuracy condition that affects measurement of the reference signal parameter. A severity of the low measurement accuracy condition has a positive correlation with the quality of a channel over which the reference signal is received. The method further includes adapting a first measurement bandwidth in response to determining that the wireless device has the low measurement accuracy condition that is positively correlated with the quality of the channel. The method further includes measuring a first reference signal parameter using the adapted first measurement bandwidth.

  • Patent number: 10716143
    Abstract: According to some embodiments, a wireless device maintains timing associated with uplink transmissions by performing steps for each of a plurality of scheduled LBT transmission opportunities. The steps include determining whether an error in a current uplink transmission timing, with respect to a reference point based on a downlink timing for a reference cell, exceeds a predetermined threshold and adjusting the timing associated with uplink transmissions, for each scheduled LBT transmission opportunity for which the error exceeds the predetermined threshold. The steps also include performing an LBT assessment to determine whether the wireless device is permitted to transmit in the scheduled LBT transmission opportunity and, for each scheduled LBT transmission opportunity in which the LBT assessment indicates that the wireless device is not permitted to transmit, reversing any adjustment to the timing associated with uplink transmissions made for that scheduled LBT transmission opportunity.

  • Publication number: 20200221396
    Abstract: Two or more formats for Power Headroom (PH) and maximum transmit power (Pcmax), and corresponding mapping tables, are defined. For example, both 6-bit and 7-bit PH and Pcmax formats are defined. In many cases, particularly when operating in the higher frequency FR2 range, a 7-bit PH or Pcmax may be required to adequately convey power headroom information. Numerous trigger criteria are defined which may indicate that one or the other format is preferred. The format selection must be communicated to the network, and subsequent Power Headroom Reports (PHR) will utilize the selected format.
