US 10,098,126 B2 · Transmitting device, receiving device, controlling node, and methods therein, for transmitting a block to the receiving device

Abstract

Method performed by a transmitting device for transmitting a block to a receiving device, both devices operating in a wireless communications network. The block comprises four bursts, which further comprise fields for Uplink State Flags (USF), Stealing Flags (SF), and data/header bits. In a first block format, USF and SF fields are interleaved and mapped over the four bursts, while data/header fields are interleaved over one burst but repeated over the four bursts. The data/header fields are overlapping with and overridden by bits from the USF field in different positions in each burst. The receiving device can receive the transmitted block and, if it is determined that the block format corresponds to the first block format, can correct a frequency offset of the receiving device in relation to the transmitting device based on the plurality of data/header bits received in at least one pair of consecutive bursts.

Dependent claims

A method performed by a receiving device configured for operation in a wireless communications network, the method comprising:

receiving, from a transmitting device in the wireless communications network, four bursts comprising a block mapped according to a selected block format, wherein the block comprises a plurality of data and header bits, a plurality of Stealing Flag (SF) bits, and a plurality of Uplink State Flag (USF) bits;
determining the selected block format based on the values of the received SF bits;
determining whether the selected block format corresponds to a first block format in which:
the plurality of data and header bits are repeated in a corresponding plurality of same first positions in all four bursts;
and
in each of the four bursts, a different portion of the plurality of data and header bits is overridden with a different portion of the USF bits;
and
if it is determined that the selected block format corresponds to the first block format, correcting a frequency offset of the receiving device, in relation to the transmitting device, based on the plurality of data and header bits received in at least one pair of consecutive bursts, of the four bursts.
