A system, apparatus, method, and computer program product used in a new radio (NR) system includes a processor and a memory storing computer-executable instructions that when executed by a processor cause a first user equipment (UE) having a plurality of antenna panels to perform Vehicle-to-Everything (V2X) sidelink (SL) radio communication with a second UE. Systems, apparatuses, methods, and computer program products for performing a discovery procedure in a NR system, for performing a reference signal communication in a NR system, controlling a timing offset in a NR system, and performing beam management in a NR system are also described.

Apparatus for performing multi-panel transmission for new radio vehicle to everything

Blind coverage for wireless devices is enhanced varying one or more transmission characteristics of a repeated transmission sent or received by apparatuses, where the repeated transmission includes, for example a Physical Downlink Shared CHannel (PDSCH) and/or a Physical Uplink Shared CHannel (PUSCH) transmissions. Varied characteristics may include a start time for each repetition, a duration for each repetition, a start frequency for each repetition, a bandwidth of each repetition, a number of repetitions for each subframe, and/or a number of repetitions for each slot. Repetitions may be within a Bandwidth Part (BWP) or span multiple BWPs. Repetitions may vary from one to another in start time, start frequency, duration, bandwidth, and slot and subframe patterns. Higher level signalling, such as Radio Resource Control (RRC) signalling may be used to control the inclusion or omission of a DeModulation Reference Signal (DMRS) in repeated transmissions.

Coverage enhancement for reduced capability new radio devices

An apparatus in accordance with the present application may monitor a sidelink (SL) connection. The apparatus includes processing circuitry that receives signals in a protocol stack to perform SL-radio link monitoring (SL-RLM), and determines, according to the signals, whether a SL-radio link failure (RLF) has occurred. The signals may include hybrid automatic repeat request (HARQ) feedback. In a case that the signals include a HARQ-NACK, the processing circuitry determines that the SL-RLF has occurred. The processing circuitry further receives configuration information related to the SL-RLM for the signals, the configuration information including configurations for measurement quantities of the signals and a condition for declaring SL-RLF, configures, according to the configuration information, lower layers of the protocol stack for the SL-RLM for the signals, and performs SL-RLM measurements of the measurement quantities.

RLM and RLF procedures for NR V2X

An electronic device including a transceiver to communicate with a network; and circuitry. The circuitry is configured to perform beam failure detection on a monitored cell; detect a beam failure on the monitored cell; determine at least one new set of candidate beam reference signals (CB-RSs) from at least one set of CB-RS configured for the device; determine if any CB-RS in the at least one new set of CB-RSs meets a criterion, and in a case that any CB-RS in the at least one new set of CB-RSs meets the criterion: select a beam corresponding to a CB-RS in the new set that meets the criterion as the new beam, and indicate the selected new beam to the network; and in a case that no CB-RS in the new set of CB-RS meets a criterion, indicate to the network that no CB-RS in the new set meets the criterion.
