  • Publication number: 20220247537
    Abstract: A method for selecting orthogonal cover codes repetition sequence for Physical Uplink Control Channel (PUCCH) transmission in a New Radio-Unlicensed (NR-U) network is provided. In embodiments disclosed herein, a set of time domain and/or frequency domain variables, ?, is first determined to be used in a function, ƒ(?), that determines a selected PUCCH sequence, rl(m), among at least two PUCCH sequences to be repeated with Orthogonal Cover Codes (OCC). Accordingly, a subset of the selected PUCCH sequence, rl(m), is repeated with OCC. By employing the method disclosed herein to determine the selected PUCCH sequence, rl(m), for repetition with OCC, it is possible to satisfy the occupied bandwidth and the maximum Power Spectral Density (PSD) requirements mandated in the NR-U network.

  • Publication number: 20220225411
    Abstract: A method for accessing a cellular communications network in unlicensed spectrum is provided. More specifically, the method is related to performing a Listen-Before-Talk (LBT) procedure prior to transmitting a Physical Random Access Channel (PRACH) preamble for accessing a New Radio-Unlicensed (NR-U) network. A User Equipment (UE) first performs the LBT procedure. If the LBT procedure is successful, the UE then generates a punctured PRACH preamble and transmits the punctured PRACH preamble. By puncturing the PRACH preamble, it is possible to create a gap(s) for performing the LBT procedure in a way that is backward compatible with existing NR-U specification and does not reduce a number of random access occasions in a slot or a mini-slot. As a result, it is possible to transmit PRACH preambles in consecutive random access occasions, thus helping to increase spectrum utilization and reduce latency in the cellular communications network.

  • Publication number: 20220200773
    Abstract: Methods and systems for handling transmissions in a serving cell Discovery Burst Transmission (DBT) window are provided. According to one aspect, a method performed at a User Equipment (UE) comprises receiving a configuration indicating a serving cell DBT window, receiving a configuration for UE-initiated Uplink (UL) transmission, and suppressing UE-initiated UL transmissions during at least a portion of the serving cell DBT window. These transmissions may be suppressed for the entire serving cell DBT window or suppressed while a base station is transmitting SSBs according to an intended transmit pattern. The suppression may start from a beginning of the serving cell DBT window or from a beginning of a first SSB transmission detected by the UE. The UE may rate match around actual transmitted SSBs that are transmitted within the serving cell DBT window due to various constraints including restrictions on channel access.

One or more of the plurality of CO measurements are obtained when the RRC state is RRC_CONNECTED. The method also includes reporting a result of one or more of the plurality of CO measurements to a network node. This might allow improved tuning of networks such as tuning of mechanisms that are used to compensate for potential CCA/LBT failures.

  • Patent number: 11290240
    Abstract: One or more nodes transmit CSI-RS symbols in a set of N CSI-RS elements, each CSI-RS element in the set corresponding to at least one resource element in a time-frequency grid of resource elements. The nodes select, from the N CSI-RS elements, a first set of CSI-RS elements to be measured by a first wireless device, the first set comprising one or several of the N CSI-RS elements. The nodes also transmit, to the first wireless device, a message comprising a first K-bit indicator identifying the first set of CSI-RS elements, wherein K<N. The nodes then receive a measurement report. The first K-bit indicator is one of a predetermined set of K-bit indicators, where each member of the predetermined set of K-bit indicators uniquely corresponds to a CSI-RS element or group of CSI-RS elements from among the N CSI-RS, according to a predetermined mapping.
