  • Patent number: 11438035
    Abstract: Systems and methods for multi-beam Channel State Information (CSI) reporting are provided. In some embodiments, a method of operation of a second node connected to a first node in a wireless communication network for reporting multi-beam CSI includes reporting a rank indicator and a beam count indicator in a first transmission to the first node. The method also includes reporting a cophasing indicator in a second transmission to the first node. The cophasing indicator identifies a selected entry of a codebook of cophasing coefficients where the number of bits in the cophasing indicator is identified by at least one of the beam count indicator and the rank indicator. In this way, feedback for both a rank indicator and a beam count indicator may be possible which may allow robust feedback and variably sized cophasing and beam index indicators.

  • Patent number: 11418240
    Abstract: A user equipment (UE) (200, 500, 1530) transmits data to a base station (100, 500, 1520) in a wireless communication network. The UE (200, 500, 1530) comprises multiple antenna ports, and selects a precoding matrix from a respective first, second, third, or fourth set of precoding matrices according to a number of spatial layers. The first, second, third, and fourth sets of precoding matrices are available for all coherence capabilities and are comprised within a larger set of precoding matrices. The larger set comprises precoding matrices that are not available for all coherence capabilities. The first, second, third, and fourth sets of precoding matrices correspond to one, two, three, or four spatial layers, respectively. The number of columns in the selected precoding matrix is equal to the number of spatial layers and each column comprises a single non-zero element and one or more zero elements.

The RACH preamble and the RACH occasion are selected based on a mapping of the SSB to the RACH preamble and the RACH occasion. The method further comprises receiving a second message from the base station as a response to the first message.

  • Patent number: 11405138
    Abstract: Systems and methods for mixed space time and space frequency block coding are provided. In some embodiments, a method of operating a first node in a wireless communication network for providing time and frequency diversity includes precoding modulation symbols intended for a second node according to two antenna ports on which they are to be transmitted. In a first subset of Orthogonal Frequency-Division Multiplexing (OFDM) symbols, mapping the precoded modulation symbols to resource elements starting first with indices corresponds to frequency. In a different subset of OFDM symbols, mapping the precoded modulation symbols to resource elements in any two adjacent OFDM symbols starting first with indices corresponds to time. In this way, transmission efficiency may be increased by not having any resource elements unused. Additional flexibility for precoding may also be provided when there is no symbol pair mapped to resource elements across two resource blocks.

  • Publication number: 20220225431
    Abstract: A method for random access which may be performed by a network node comprises determining an association between a downlink transmission and an uplink transmission (e.g. an association between a synchronization signal and physical broadcast channel block and a random access occasion) in a two-step random access procedure, based at least in part on random access resource configuration for the two-step random access procedure (e.g. based at least in part on whether random access resource is shared by the two-step random access procedure and a four-step random access procedure). The method further comprises transmitting information indicating the association to a terminal device. Accordingly, an association between a synchronization signal and physical broadcast channel block and a random access occasion in a two-step random access procedure can be configured flexibly and efficiently.
