A training packet sending method and apparatus, where the method includes generating, by a first device, a training packet, where the training packet includes a preamble, a header, and a training field, and the header includes at least a legacy header, and repeatedly sending, by the first device, the preamble using N channels, sending the legacy header in the header using the N channels, and sending the training field to at least one second device using H channels of the N channels, where N is greater than 1, and H is greater than 1 and less than or equal to N.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a synchronization signal (SS) block index associated with a SS block; scramble a physical broadcast channel (PBCH), associated with the SS block, based at least in part on the SS block index; and transmit the SS block including a tertiary synchronization signal (TSS) and the PBCH, wherein the TSS includes information that identifies the SS block index associated with the SS block, and wherein the TSS is frequency division multiplexed with the PBCH in two or more orthogonal frequency-division multiplexed (OFDM) symbols of the SS block. Numerous other aspects are provided.

Mixture of implicit and explicit signaling of the Synchronization Signal Block (SSB) time index for 5G New Radio. In NR, multiple SSBs (each containing PSS, SSS and PBCH) are sent on different beams, and on multiple time occurrences. The UE when detecting the SSB has therefore to identify the SSB time instance and the beam ID used by the gNB. This detection is allowed by said SSB time index. If sent on the PBCH, this prevents soft combining between PBCH time instances. It is therefore proposed to send the SSB time index via the DMRS interleaved with the PBCH. Problem: overhead would be too high for DMRS solution only. Solution: Part of the bits (the LSBs) of the SSB time index are signaled implicitly via the relative position of PSS, SSS and PBCH within a SSB. The other bits are explicitly sent using DMRS scrambling.

Techniques are described for carrier frequency offset (CFO) and channel estimation of orthogonal frequency division multiplexing (OFDM) transmissions over multiple-input multiple-output (MIMO) frequency-selective fading channels. A wireless transmitter forms blocks of symbols by inserting training symbols within two or more blocks of information-bearing symbols. The transmitter applies a hopping code to each of the blocks of symbols to insert a null subcarrier at a different position within each of the blocks of symbols, and a modulator outputs a wireless signal in accordance with the blocks of symbols. A receiver receives the wireless signal and estimates the CFO, and outputs a stream of estimated symbols based on the estimated CFO.

A communication apparatus includes a receiver and a decoder. The receiver includes a plurality of antenna elements and, in operation, receives from a base station apparatus a modulated signal mapped to one of a plurality of subframes defined in a frame corresponding to a communicable range to which the communication apparatus belongs. The plurality of subframes are defined by time-division, frequency-division, or time-and-frequency division of the frame. A maximum number of modulated signals that can be simultaneously transmitted in a subframe from the base station apparatus varies depending on the communicable range. The decoder, in operation, decodes the received modulated signal.

Systems, apparatuses, and methods are described for wireless communications. A wireless device may distribute power for various transmission types based on a priority, which may be received from a base station.

A method and apparatus for performing measurement based on synchronization signal (SS) blocks in a wireless communication system is provided. A user equipment (UE) which supports a new radio access technology (NR) receives a SS block measurement timing configuration (SMTC) from a network, and performs measurement based on the SS blocks in a duration which is determined based on the SMTC. The SS blocks are included in an active bandwidth part (BWP).

A wireless device receives configuration parameters indicating resource configurations of reference signals for a layer 1 reference signal received power (RSRP) reporting of a secondary cell. A control element indicating activation of the secondary cell is received. In response to the control element, a layer 1 RSRP report is transmitted. The layer 1 RSRP report comprises: a first field indicating a reference signal of the reference signals of the secondary cell; and a second field indicating a layer 1 RSRP value of the reference signal.

There is disclosed a method of operating a transmitting radio node in a wireless communication network, the method including transmitting reference signaling based on a reference pilot sequence, the reference pilot sequence being one of a set of reference pilot sequences, at least one reference pilot sequence of the set being a subsequence of another reference pilot sequence of the set. The disclosure also pertains to related devices and methods.
