Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.

Abstract: A 3GPP LTE protocol enhancement realizes the full benefit of discontinuous reception (DRX) in Long Term Evolution networks by coordinating and aligning DRX operations for conserving power and timing overhead. A dual connectivity enabled User Equipment (UE) comprising a processor and transceiver is configured to align DRX configuration between counterpart Evolved Node Bs (eNB)s, wherein counterpart eNBs are a Master eNB (MeNB) and a Secondary eNB (SeNB) simultaneously connected to the UE, communicate system frame timing and system frame number (SFN) information between the counterpart eNBs, align DRX start offset (drxStartOffset) values for the counterpart eNBs according to the communicated system frame timing and SFN information to compensate for offsets in system frame timing, and allow the start of a DRX ON duration at specific frame or sub-frame times determined by the drxStartOffset values, after the expiration of a DRX inactivity timer.

Abstract: Embodiments of a network User Equipment (nUE), wearable User Equipment (wUE), and methods for sidelink communication are generally described herein. The nUE may transmit a control channel that allocates a subframe as either a downlink subframe or an uplink subframe for a sidelink communication between the nUE and a wearable User Equipment (wUE). When the control channel allocates the subframe as a downlink subframe, the nUE may contend for access to channel resources. The contention may include transmission of a transmitter resources acquisition and sounding (TAS) channel in a physical resource block (PRB) and an attempted detection of a receiver resources acquisition and sounding (RAS) channel from the wUE in the PRB. When the control channel allocates the subframe as an uplink subframe, the wUE may contend for access to the channel resources.

Abstract: Embodiments of a system and method for random access and scheduling request for new radio things sidelink are generally described herein. In some embodiments, a nUE (network user equipment) schedules a RA (random access) resource in a control channel. The nUE decodes a TAS (transmitter resource acquisition and sounding) payload, received from a wUE (wearable user equipment) in a PRB (physical resource block) addressed to a RA-ID (random access identifier) associated with the nUE. The nUE encodes, in response to decoding the TAS payload, a RAS (receiver resource acknowledgement and sounding) payload in the PRB. The nUE decodes initial access content received via a data channel from the wUE, the initial access content including a pro posed temp ID (temporary identifier) for addressing the wUE. The nUE encode, in response to the initial access content, an ACK (acknowledgement), addressed to the wUE, to accept initial access of the wUE.
