  • Publication number: 20210368539
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may transmit a random access message (e.g., msgA or msg3) using a modulation and coding scheme (MCS) selected based on the frequency band and subcarrier spacing utilized for the random access procedure. The MCS may depend on the frequency band and a size of the SCS satisfying a threshold. In some cases, a base station may select and indicate the MCS for the UE. Additionally or alternatively, a phase tracking reference signal may be transmitted along with a random access message to correct for phase noise.

  • Publication number: 20210360629
    Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may transmit, to a base station, an indication of a capability of the UE to switch from monitoring a set of frequency resources according to a first subcarrier spacing (SCS) to monitoring the set of frequency resources according to a second SCS, less than the first SCS. The indication may indicate an amount of time for the UE to switch between SCSs. The UE may receive, from the base station, signaling that indicates a configuration for monitoring the set of frequency resources according to the second SCS (e.g., a configuration for a reduced SCS window). The UE may switch from monitoring the set of frequency resources according to the first SCS to monitoring the set of frequency resources according to the second SCS based on receiving the configuration for monitoring the set of frequency resources.

  • Publication number: 20210352729
    Abstract: A UE, as a part of a RACH communication procedure, may transmit a first sequence within a first set of resources having a first SCS and a second sequence within a second set of resources having a second SCS greater than the first SCS. The second sequence is transmitted with a cyclic prefix greater than inverse of the first SCS divided by a sequence length of the first sequence. The first sequence is a first PRACH preamble. The second sequence may be a second PRACH preamble, an SRS sequence, or DMRS. The UE may repeat the transmission of the first sequence for a first number of times and repeat the transmission of the second sequence for a second number of times independent of the first number.

  • Publication number: 20210352601
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an energy per resource element (EPRE) ratio between a synchronization signal block (SSB) symbol containing a primary synchronization signal (PSS) and an SSB symbol containing a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), or both, based on an operating band for the UE, a bandwidth of the SSB symbol containing the PSS and the SSB symbol containing the SSB, the PBCH, or both. The EPRE ratio may be based on maximum regulatory equivalent isotropically radiated power (EIRP) limits, maximum regulatory power spectral density (PSD) limits for the band, or both. The EPRE ratios may be different for different SSB symbols, when different SSB symbols have different bandwidths. A base station may configure and transmit, and a UE may receive, the SSB according to the identified EPRE ratio.

  • Publication number: 20210328843
    Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.
