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.

DMRS for 5G things communication system

Embodiments describe methods and apparatuses for a software-defined cellular system with distributed antennas and baseband units (BBUs). The BBUs may be implemented with software defined network (SDN) technology in some embodiments. Embodiments include provision of a dynamic connection between distributed antennas and a BBU to serve a scheduled UE. In some embodiments, a BBU may select a scheduling set of antennas that may provide a desired connection with the UE. Other embodiments may be described and/or claimed.

Software defined cellular system with distributed antennas

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.

An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to obtain channel information and data information for a user equipment (UE) device, determine control information for the UE device based on the obtained channel information and data information, generate a channel format for the determined control information and having varied subband sizes, and provide the channel format to the RF interface for a downlink transmission to the UE device.is configured to be employed within a base station.

Embodiments of the present disclosure describe systems, devices, and methods for preprocessing in a base station of a multiple-input multiple-output (MIMO) wireless system. In embodiments, remote radio unit (RRU) circuitry may control radio communication related to the MIMO wireless system, including applying a user equipment (UE)-specific spatial filter.

Base station front end preprocessing

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.

Random-access and scheduling-request in new radio-things sidelink

A method of processing signals in a radio processing apparatus of a base station may include obtaining a plurality of aggregated data symbols, wherein each of the plurality of aggregated data symbols corresponds to a receive terminal of a plurality of receive terminals of the base station and is composed of transmitted data symbols from a plurality of transmit terminals; applying a compression filter to the plurality of aggregated data symbols to reduce the plurality of aggregated data symbols into a plurality of isolated data symbols, the compression filter being based on channel estimates between the plurality of receive terminals and the plurality of transmit terminals; and transmitting the plurality of isolated data symbols to a baseband processing apparatus of the base station.

Methods of processing signals, apparatus, and base station

Systems and methods of providing communications between UEs are generally described. A notification resource indicating subsequent transmission of a discovery message is transmitted from a UE to another UE using a discovery ID selected from a limited number of discovery IDs stored in the other UE. The other UE transmits a random access request to the UE having a temporary ID. The UE may not respond if the temporary ID is already used or may transmit data transmission information scrambled by the temporary ID. The other UE transmits a contention resolution PDU to the UE and may receive an ACK to indicate ID contention is not present, or either no response or a NACK to indicate the presence of ID contention. The other UE may either select a new temporary ID or use a backoff timer to retransmit the random access request at a random time.

A method for determining a precoding matrix for a MIMO transmitter based on a weighted MMSE algorithm is disclosed. A precoding module identically transforms a first matrix expression into a second matrix expression. The first matrix expression comprises a matrix inversion operation of a quadratic matrix having a rank equal to a number of antennas of the MIMO transmitter. The second matrix expression comprises a matrix inversion operation of a quadratic matrix having a rank equal to a number of receivers scheduled for the MIMO transmitter.

Embodiments described herein relate generally to efficient transmission of data over a radio network between a user equipment ('UE') and a network node. The UE may adapt packets from TCP to a private protocol and transmit those data packets to the network node. The UE may use ARQ data from link layer circuitry to locally generate TCP ACK data for TCP layer circuitry. At the network node, the private-protocol data packets may be adapted to TCP and transmitted to a remote host over the Internet so that the TCP semantic may be maintained between the UE and the remote host. Other embodiments may be described and/or claimed.
