  • Patent number: 11818602
    Abstract: Power headroom reporting and report handling are discussed in the context of a Physical Uplink Shared Channel (PUSCH), on which a user equipment (UE) has no valid uplink grant, and a Physical Uplink Control Channel (PUCCH) on which a UE has no transmission. Under these circumstances, it is not possible to directly calculate one or more parameters which are used to calculate power headroom. Accordingly, exemplary embodiments provide for predetermined, known values to be used by the UE to calculate the power headroom, and by the eNodeB to understand the meaning of a received power headroom report.

  • Patent number: 11818719
    Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

  • Patent number: 11817947
    Abstract: A modulation technique, such as for example either Pi/2 BPSK or QPSK, is selected for transmission, based on a characteristic of the data to be transmitted, or the physical channel over which it is to be transmitted. The data characteristic may be the coding rate, or characteristics indirectly related to the coding rate, such as the number of coded bits or number of uncoded bits (payload size). The physical channel characteristic may for example be the physical channel bandwidth, the physical channel length, a number of physical channel modulation symbols, a number of the physical channel resource elements used for the data to be transmitted, or a number of the physical channel modulation symbols carrying the data to be transmitted.

  • Publication number: 20230345499
    Abstract: A network node, such as a base station, identifies radio resources within an overall bandwidth using a first resource referencing scheme, while a wireless communication device identifies radio resources within an allocated portion of the overall bandwidth using a second resource referencing scheme. Advantageously, the device correctly identifies given radio resources pointed to by a resource identifier expressed according to the first resource referencing scheme, by translating the resource identifier into the second resource referencing scheme according to mapping information that relates the two schemes. Correspondingly, the network node enables the wireless communication device to perform such translations by providing the mapping information either implicitly or explicitly.
