  • Patent number: 11616671
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) or base station may generate orthogonal frequency division multiplexing (OFDM) symbols based on a permutation matrix (P) that permutes guard interval (GI) samples and data samples such that the OFDM symbols have power values across the symbols that are supportable by a transmitting device. The permutation matrix may map GI inputs to a subset of subcarriers for an OFDM communication, where the permutation matrix determined based at least in part on a first number of columns of a sub-matrix of a first matrix. The first matrix may be an inverse fast Fourier transform (IFFT) matrix, or may be a product of the IFFT matrix and a subcarrier mapping matrix. The first number of columns may correspond to a number of subcarriers that carry time-domain GI samples.

  • Patent number: 11617171
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, in a first time slot, a cyclic prefix (CP) at a start end of the first time slot, data content, and tail samples at a tail end of the first time slot. The wireless communication device may initiate a gap action, such as switching beams, during receipt of the tail samples, the gap action taking place within a time gap formed by at least the tail samples. The time gap may also include a CP of a second time slot that is subsequent to the first time slot. The wireless communication device may complete the gap action within the time gap. Numerous other aspects are described.

  • Patent number: 11616594
    Abstract: In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

  • Publication number: 20230084448
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.

  • Patent number: 11606763
    Abstract: Methods, systems, and devices for wireless communications provide techniques for multiplexing, in a frequency domain, a synchronization signal block (SSB) and a control resource set (CORESET) to form a multiplexed block that is transmitted using a set of symbols. A base station may transmit multiple multiplexed blocks using multiple different beams with a switching gap provided between each multiplexed block that allows for switching of radio frequency (RF) components between different beams. The switching gap is longer than a duration of a cyclic prefix (CP) that is associated with each symbol of the set of symbols of each multiplexed block. Within one or more of the multiplexed blocks, an associated SSB may use a different waveform than the CORESET. The multiplexed blocks may use a common reference signal for both the SSB and CORESET.

    Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may transmit a random access preamble to a base station as part of a random access procedure between the UE and the base station. To generate the random access preamble, the UE may repeat each time domain sample of a base sequence on a per-sample basis to obtain a repeated sequence that includes multiple repetitions of each time domain sample of the base sequence, with repetitions of the same sample being consecutive within the repeated sequence. The UE may perform such sample-wise repetition before adding a cyclic prefix (CP) to the repeated sequence or after adding a base CP to the base sequence.
