Synchronisation signaling for wireless communication network

Radio communication systems, devices and methods for enabling variable subband configuration of one or more search spaces. In a first time interval, a UE attempts to decode one or more control channels on downlink or sidelink resources of a first sub band configuration. In a second time interval, the UE attempts to decode one or more control channels on downlink or sidelink resources of a second sub band configuration. The first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Network architecture, methods, and devices for a wireless communications network

According to certain embodiments, a method for use in a wireless device for transmitting uplink control information (UCI) on grant-free resources comprises reserving a subset of time/frequency resources of a grant-free uplink channel for transmitting UCI, and upon determining the wireless device has UCI to transmit on the grant-free uplink channel, transmitting the UCI to a network node in the reserved subset of time/frequency resources.

A method, system and apparatus are disclosed. A network node configured to communicate with a wireless device is provided. The network node includes processing circuitry configured to indicate, in downlink control information, DCI, a first modulation and coding scheme, MCS, associated with first transport block, TB, indicate, in the DCI, a second MCS associated with a second TB where the first MCS is indicated by a first MCS field size and the second MCS is indicated by a second MCS field size less than the first MCS field size, and communicate with the wireless device based on the first MCS and the second MCS.

Modulation and coding scheme (MCS) signalling for multi-carrier scheduling

Methods and apparatuses disclosed herein enable the use of Demodulation Reference Signal (DMRS) sequences that are numbered relative to an overall system bandwidth, while simultaneously enabling wireless communication devices to determine the DRMS sequence elements mapped to their scheduled bandwidths within the system bandwidth. Advantageously, the wireless communication devices need not know the system bandwidth, or even be aware of where their scheduled bandwidths reside within the system bandwidth.

Methods and apparatuses for signaling and determining reference signal offsets

The present disclosure described systems and methods for providing OTT services to a UE. An exemplary OTT-providing host computer includes a transceiver, a processor, and memory collective configured to provide the OTT service by initiating transmission of user data to the UE. To transmit the user data from the host computer to the wireless device, a network node sends a first control message for assigning a PDSCH, the first control message comprising a first MCS indication as described. The network node sends to the wireless device a second control message for assigning a PDSCH, the second control message comprising a second MCS indication as described. The network node transmits the user data thereafter.

Devices, systems, and methods described herein may improve aperiodic CSI-RS handling in mixed numerology environments. An exemplary method includes operations of receiving a downlink control information (DCI) message carried by a Physical Downlink Control Channel (PDCCH) on a second carrier, wherein the second carrier uses a second OFDM numerology, obtaining an aperiodic CSI-RS slot offset from the DCI message, determining a reference slot in the first numerology, determining the slot of the aperiodic CSI-RS based on the reference slot and the aperiodic CSI-RS slot offset, and receiving or transmitting the aperiodic CSI-RS in the determined slot.

The disclosure also pertains to related devices and methods.
