Abstract:
A user equipment (UE) may determine one or more nominal time-domain windows (TDWs) for demodulation reference signals (DMRS) bundling for physical uplink control channel (PUCCH) transmissions of a PUCCH repetition. A start of a new actual TDW for the DMRS bunding is determined in response to an event which causes power consistency and phase continuity not to be maintained across the PUCCH transmissions of the PUCCH repetition. The UE may maintain power consistency and phase continuity within the new actual TDW across two PUCCH transmissions of the PUCCH repetition. The event may comprise a use of different power control parameters for the two of the PUCCH transmissions of the PUCCH repetition within one of the nominal TDWs.
Abstract:
A user equipment (UE) configured for physical uplink shared channel (PUSCH) repetition in an fifth-generation (5G) new radio (NR) network decodes a downlink control information (DCI) format that includes a scheduling grant for a PUSCH transmission. For a codebook-based PUSCH transmission, the DCI format indicates at least a first and a second transmit precoder matrix indicator (TPMI) index for PUSCH repetition. The UE may apply a precoder matrix determined from the first TPMI index to encode a PUSCH for a first PUSCH transmission occasion of the PUSCH repetition and may apply a precoder matrix determined from the second TPMI index to encode the PUSCH for a second PUSCH transmission occasion. For a non-codebook-based PUSCH transmission, the DCI format indicates at least a first and a second sounding reference signal (SRS) resource indicator (SRI) for PUSCH repetition. The UE may apply the first SRI to encode the PUSCH for the first PUSCH transmission occasion and may apply the second SRI to encode the PUSCH for the second PUSCH transmission occasion.
Abstract:
Technology for an eNodeB operable to control communications at a relay user equipment (UE) is disclosed. The eNodeB can select the relay UE to relay proximity services (ProSe) traffic between the eNodeB and a remote UE based on one or more relay quality indicators associated with the relay UE. The eNodeB can communicate, to the relay UE, control signaling to configure one or more orthogonal timelines to cause the relay UE to resolve ProSe communications between the relay UE and the remote UE that conflict with uplink hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) transmissions from the relay UE to the eNodeB.
Abstract:
Embodiments of a UE to operate in accordance with a device-to-device (D2D) communication mode are disclosed herein. The UE may include hardware processing circuitry to determine a synchronization reference time based on reception of signals from an eNB. The hardware processing circuitry may be further to, during a D2D communication session, transmit Multi-Time Transmission Interval Bundle Groups (MTBG) of data symbols during a first group of Data Transmission Intervals (DTI) and refrain from transmission of data symbols during a second group of DTIs. Starting times of the DTIs may be based at least partly on the synchronization reference time. The hardware processing circuitry may be further to transmit, during an in-network communication session, data symbols according to a Time Transmission Interval (TTI) reference time synchronized to the synchronization reference time.
Abstract:
In embodiments, apparatuses, methods, and storage media may be described for mapping media access control (MAC) protocol data units (PDUs) that are used to transmit scheduling assignment (SA) discovery, and/or device-to-device (D2D) data. Embodiments herein may describe how one or more MAC PDUs may be mapped into a time resource pattern for transmissions (T-RPT). Embodiments herein may further describe examples of how and when a UE may skip subframes in transmissions of the SA and/or data. Additionally, embodiments herein may further describe examples of how a UE may behave if the UE cannot transmit one or more scheduled instances of SA or data. Additionally, embodiments herein may describe resolution of collisions of D2D discovery messages in the time domain. Other embodiments may be described and/or claimed.
Abstract:
Embodiments disclosed herein are directed to new mechanisms of resource allocation for transmission of positioning or ranging (e.g., sounding) reference signals. The embodiments may provide flexible and/or efficient resource allocation, and may improve accuracy of user positioning. The techniques described herein may be applied for multiple use cases, including UAS, V2X, IIoT, etc.
Abstract:
A non-transitory computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for low latency NR positioning in a 5G NR network and cause the UE to perform operations comprising decoding configuration signaling received from a base station. The configuration signaling includes measurement gap information and scheduling information for a UE measurement report. A downlink (DL) positioning reference signal (PRS) received from the base station is decoded. Positioning measurements are performed using the DL PRS. The positioning measurements are performed based on a measurement gap corresponding to the measurement gap information. The UE measurement report is encoded for a UL transmission to the base station based on the scheduling information. The UE measurement report includes the positioning measurements.
