摘要:
Various embodiments herein provide techniques for sending and receiving inter-user equipment (UE) coordination information for sidelink communication. The inter-UE coordination information may be provided via sidelink control information (SCI) and/or medium access control-control element (MAC-CE). Aspects regarding resource reservation and/or indication for UE coordination information are described. Additionally, new SCI formats for inter-UE coordination information are provided. Other embodiments may be described and claimed.
摘要:
An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to decode radio resource control (RRC) signaling from an authorized V2X network entity. The RRC signaling including configuration information to activate a sidelink transmit (TX) bandwidth part (BWP) of a plurality of sidelink TX BWPs within a sidelink carrier. Data is encoded for transmission to a second UE using a first sidelink signal. The processing circuitry is to cause transmission of the encoded data via the first sidelink signal. A bandwidth of the first sidelink signal during the transmission is within the activated sidelink TX BWP.

An apparatus of a UE includes processing circuitry coupled to a memory. To configure the UE for NR V2X sidelink communication, the processing circuitry is to decode SCI received from a second UE via a PSCCH, the SCI indicating sidelink resources from a sidelink resource pool reserved by the second UE. A set of candidate sidelink resources is determined for reservation by the UE from the sidelink resource pool is determined. The set is divided into multiple time slots and frequency sub-channels and is non-overlapping in time with the sidelink resources reserved by the second UE. A second SCI is encoded for transmission via the PSCCH, the second SCI indicating a plurality of sidelink resources from the set of candidate sidelink resources. A PSSCH is encoded for transmission, the PSSCH is encoded to include a transport block mapped across the plurality of sidelink resources.
摘要:
Increasing a number of orthogonal time-domain transmission opportunities in a Proximity Services (ProSe) traffic generation period can reduce over-air congestion and collision in long term evolution (LTE) communications. Resource configurations can be adjusted, including providing a new physical layer numerology, reducing transmission time (TTI) interval duration, providing a smaller sidelink control information period, configuring logical sidelink control periods and/or multiplexing of control and data transmissions.

A user equipment (UE) can receive, from an eNodeB, a serving PLMN system information block (SIB)19 for a carrier frequency of a serving PLMN of the UE. The UE can acquire inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information from the SIB19. The UE can process a non-serving PLMN SIB19 for one or more carrier frequencies of a non-serving PLMN using the inter-frequency and inter-PLMN discovery system information acquisition assistance signaling information. The UE can identify inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information for the one or more carrier frequencies of the non-serving PLMN to enable the UE to perform device-to-device (D2D) discovery with a UE in the non-serving PLMN according to the inter-frequency and inter-PLMN discovery announcement rate information and monitoring control configuration information.
摘要:
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.

The present disclosure provides for a V2X communication configuration based on geographical location. Configuring the V2X communication can include generating a partitioned cell communication area; determining a presence of a UE in a geographical location of the partitioned cell communication area, wherein the UE is associated with a vehicle; and configuring a UL communication between the UE and the V2X server based on the geographical location.

Techniques for adjacent channel interference mitigation are described. In one embodiment, for example, a user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to associate the UE with a pico evolved node B (eNB) in a time-division duplex (TDD) picocell, identify an incongruent uplink (UL) sub-frame for the picocell, and select an enhanced UL transmit power for the incongruent UL sub-frame. Other embodiments are described and claimed.

摘要:
A user equipment (UE) is configured to synchronize with an independent synchronization source (I-SS) based on a first synchronization signal received from the I-SS. The UE is configured to determine whether a received signal strength from the I-SS is below a threshold value. The UE is configured to, in response to determining that the I-SS is below the threshold value, transmit a second synchronization signal propagating synchronization information derived from the I-SS to one or more peer UEs out of range of the I-SS. The second synchronization signal comprises a device-to-device synchronization signal (D2DSS).
