  • Publication number: 20210136767
    Abstract: A client device for wireless communication has a transceiver, and a processor. The transceiver receives frequency resource information to indicate a set of frequency resources for a PRACH preamble transmission. The frequency resource information indicates each frequency resource having: interlace information of B-IFDM allocation, resource element allocation information indicating a subset of resource elements within each block of the B-IFDM interlace, and resource element spacing information, such that a resource element within a block of the B-IFDM interlace is allocated for the transmission of one PRACH preamble according to a T-IFDM allocation. The resource element allocation is repeated in each block of the B-IFDM interlace. The processor is configured to select a frequency resource based on the received frequency resource information, and generate a PRACH preamble to be transmitted on the selected frequency resource.

  • Publication number: 20210076425
    Abstract: A network access node and a client device for generating and using cubic phase polynomial sequences (si, sj) of length L with a third order coefficient value a3 belonging to the subset of sequences (Sk) are described. The network access node transmits a control message to the client device, wherein the control message indicates the cyclical shift value NCS and the third order coefficient value a3. The client device receives the control message and determines a cubic polynomial phase sequence (si) belonging to the subset of sequences (Sk) based on the cyclical shift value NCS and the third order coefficient value a3. The client device thereafter transmits the determined cubic polynomial phase sequence (si) as a random access preamble to the network access node.

  • Publication number: 20200007216
    Abstract: Devices, methods and computer programs for wireless communications with rotational beam management are disclosed. Information from past beam tracking stages can be used for a next beam tracking stage, since a next beam codebook to be used for beam scanning depends on an earlier beam codebook.

  • Publication number: 20180337717
    Abstract: The disclosure relates to a first communication device for a wireless communication system, the first communication device comprising: a processor, a cascade precoder including an outer precoder and an inner precoder, and a transceiver; wherein the processor is configured to determine the inner precoder; wherein the transceiver is configured to transmit a first pilot sequence to a second communication device; wherein the transceiver is configured to receive a first channel estimation from the second communication device; wherein the processor is configured to determine the outer precoder based on the first channel estimation; wherein the transceiver is configured to transmit at least one of a data sequence and a pilot sequence to the second communication device.
