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.

Variable subband configuration of search space

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.

UCI on grant-free PUSCH

A method for use in a transmitter includes sending a transmission comprising a transport block (TB) comprising a plurality of code blocks (CBs) arranged in one or more code block groups (CBGs). Each code block group includes one or more code blocks and each code block includes a plurality of coded bits. The transmission is sent to a receiver configured to use multi-bit hybrid automatic repeat request (HARQ) feedback per transport block. The method further includes receiving HARQ ACK or NACK feedback from the receiver one or more of the one or more code block groups of the transport block. The method further includes determining a number of code blocks or code block groups to send to the receiver in a retransmission based on at least the received HARQ ACK or NACK feedback.

HARQ handling for nodes with variable processing times

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

There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an Orthogonal Frequency-Division Multiplexing (OFDM) symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

Search space monitoring

Limited uplink bandwidth radio network devices are supported on wide bandwidth uplink carriers by configuring and controlling the use of multiple control regions within the uplink carrier bandwidth. In some embodiments, the total bandwidth of the uplink carrier is divided into a plurality of sub-band portions, wherein each sub-band portion includes at least one control region nominally dedicated to the transmission of uplink control signaling. Radio network devices are configured with a specified portion of the uplink carrier bandwidth for use for uplink transmission, which includes at least one control region. Radio network devices may be provisioned or provided with information regarding control regions reserved for control signaling by other radio network devices. The radio network devices may be dynamically configured to allow or suppress uplink data signaling in specified control regions, or portions thereof.

Selective suppression of uplink transmission in control regions

Radio network nodes, wireless devices, and related methods are provided in which a pseudo-random sequence initialization value, which is used during the generation of pseudo-random and/or scrambling sequences, is based, at least in part, on a first identifier, wherein the first identifier is equal to a first parameter if the first parameter has been configured and if a second identifier corresponds to a wireless-device-specific identifier.

Scrambling of physical channels and reference signals in wireless communication networks

A system and method for providing time domain allocations in a communication system. In an embodiment, an apparatus operable in a communication system and including processing circuitry is configured to receive an indication of a time domain allocation in downlink control information associated with a radio network temporary identifier ('RNTI') identifying the apparatus, and employ the time domain allocation associated with the RNTI for transmissions associated with the apparatus. In another embodiment, an apparatus operable in a communication system and including processing circuitry is configured to associate a time domain allocation with a RNTI identifying a user equipment, and provide an indication of the time domain allocation in downlink control information to allow the user equipment to employ the time domain allocation associated with the RNTI for transmissions associated therewith.

System and method for providing time domain allocations in a communication system

There is disclosed a method of operating a feedback radio node in a wireless communication network.

Embodiments herein disclose e.g. a method performed by a wireless device () for handling communication for the wireless device in a second wireless communication network. The second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency in uplink transmissions. The wireless device receives from a radio network node (), an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses Frequency Division Duplex (FDD). The wireless device further applies the second shift in frequency to uplink transmissions, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network or a shift in frequency to the subcarrier grid of the second wireless communication network.

Radio network node, wireless device and methods performed therein for handling communication in a wireless communication network

Arrangement for switching between an active bandwidth part and the target bandwidth part are disclosed. A method includes selecting one or more resource blocks comprised in the target bandwidth part for a transmission or reception between the wireless device and the network node. The selected resource blocks to be used in the target bandwidth part are indicated in a resource allocation field of a downlink control channel information in the active bandwidth part. The allocation field includes information bits and the resource allocation field in the active bandwidth part and the information bits are configured based on a target bandwidth part resource allocation type. The target bandwidth part resource allocation type indicates whether the information bits have a bitmap corresponding to one or more resource block groups or an integer value corresponding to a starting resource block and a length of the allocation in resource blocks.

Bandwidth part switching

To configure uplink sounding signal transmission in a wireless communication network, sets of configuration parameters for uplink sounding signal transmissions are determined for a given mobile terminal. Each of the sets of configuration parameters comprises a priority, a frequency-domain parameter and a time-domain parameter. The sets of configuration parameters are transmitted to the mobile terminal, thereby configuring the mobile terminal to generate different sounding signals and use the priorities to select from among the different sets of configuration parameters in the event of a sounding signal transmission collision.

Channel sounding using multiple sounding configurations

A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode. In the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.
