Abstract: This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

Abstract: Example wireless communications methods and apparatus with two-way beam failure recovery are disclosed. One example method includes receiving a downlink beam failure recovery request by a network device from a client device indicating at least one new downlink candidate beam determined to replace at least one failed downlink beam. The network device detects at least one failed uplink beam, determines at least one new uplink candidate beam to replace the detected at least one failed uplink beam, and generates uplink redirection information indicating the determined at least one new uplink candidate beam. A response including the generated uplink redirection information is generated by the network device, and transmitted to the client device.

Abstract: The present disclosure relates to a client device and a network access node for transmitting and receiving a random access preamble which comprises a division of a set of resource blocks available for transmission of the random access preamble into at least two subsets of resource blocks, wherein each resource block in the set of resource blocks comprises a plurality of subcarriers, a first selection of resource blocks within the first subset of resource blocks and a second selection of resource blocks within the second subset of resource blocks, wherein the first selection of resource blocks is different to the second selection of resource blocks, and a mapping of a modulation sequence of the random access preamble onto at least one subcarrier in each selected resource block. Thereby, lower side-lobes of the auto-correlation function is achieved. Furthermore, the present disclosure also relates to corresponding methods and a computer program.

Abstract: A network node for a wireless communication system includes a processor and a transceiver, the processor being configured to generate a set of at least two synchronization signal sequences; construct a synchronization signal for each synchronization signal sequence to create a set of synchronization signals, such that each of the synchronization signals in the set of synchronization signals has an auto correlation and cross correlation below a threshold value with any other synchronization signal in the set of synchronization signals; generate a set of directional beam patterns, wherein each beam pattern in the set of directional beam patterns corresponds to one of the synchronization signals in the set of synchronization signals; and wherein the transceiver is configured to transmit the synchronization signals in the set of synchronization signals using the beam pattern for each synchronization signal over a same time frequency resource.
