A wireless device () receives a downlink control information message () on a physical downlink control channel. In some embodiments, the downlink control information message () schedules two or more non-redundant downlink transmissions to be transmitted to the wireless device () in respective transmission time intervals, TTIs, on a first downlink serving cell (A) and one or more non-redundant downlink transmissions to be transmitted to the wireless device () in one or more respective TTIs on a second downlink serving cell. In other embodiments, the downlink control information message () schedules one or more non-redundant uplink transmissions to be transmitted from the wireless device () in one or more respective TTIs on a first uplink serving cell (A) and one or more non-redundant uplink transmissions to be transmitted from the wireless device () in one or more respective TTIs on a second uplink serving cell (B).

Transmission scheduling in a wireless communication network

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

A method performed in a system comprising a joint traffic direction scheduler configured to coordinate time-division-duplexing (TDD) transmissions for multiple cells comprises obtaining TDD operation information from each of the cells, determining, based on the obtained TDD operation information, a transmission direction to be used by each of the cells during one or more transmission time intervals (TTIs), and indicating to the cells the determined transmission direction.

Coordination of duplex directions in NR TDD system

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

The disclosed embodiments relate to a method performed by an apparatus and also relate to an apparatus. The method includes transmitting to a communication device a burst including a subframe; receiving from the communication device a HARQ values associated with the subframe; and determining a random backoff contention window size based on the received HARQ values and also based on previously unused HARQ feedbacks. The apparatus is configured to perform the method steps described above.

Systems and methods for reducing cross-link interference in a wireless system are disclosed. In some embodiments, a method of operation of a wireless device in a wireless system comprises receiving, from a serving Access Point (AP), wireless device specific Sounding Reference Signal (SRS) or Demodulation Reference Signal (DMRS) configuration information for one or more potential aggressor wireless devices. The method further comprises performing one or more measurements on at least one of the one or more potential aggressor wireless devices using the wireless device specific SRS or DMRS configuration information for the at least one of the one or more potential aggressor wireless devices and reporting at least one of the one or more measurements to the serving AP. In this manner, cross-link interference measurement and reporting is enabled.

Method for performing an unscheduled uplink transmission by a user equipment UE, in an unlicensed portion of a radio spectrum, the method comprising: performing, by the UE, a listen before talk, LBT, operation in the unlicensed portion of the radio spectrum, wherein the LBT operation includes sensing the portion of the radio spectrum for a pre-determined minimum amount of time for traffic; and performing, if no traffic was sensed, the unscheduled uplink transmission, by the UE, of data in an unscheduled mode of operation for at least one transmission burst.

Method and apparatuses for performing unscheduled uplink transmissions on an unlicensed band

According to certain embodiments, a method in a first network node scheduling time-division-duplexing (TDD) transmission for a first cell is provided. The method includes receiving transmission direction planning information from a plurality of other network nodes scheduling TDD transmissions for other cells. At least one transmission direction plan of the first network node is adapted based on the transmission direction planning information received from the plurality of other network nodes.

System and method for distributed coordination of duplex directions in a NR system

The invention relates to a method for operating a network node in a wireless network. The method includes detecting cross-link interference on one or more time slots used when communicating with the network node, identifying an aggressor node generating the detected cross link interference, and transmitting, to the aggressor node, a signal having an indication of slot number and/or a transmission direction of the detected cross link interference.

A first wireless node of a wireless communication system is associated with a first cell having a first cell identity. The first wireless node obtains information relating to a set of wireless nodes which use at least one overlapping communication resource that is also used by at least one second node in the first cell. The first wireless node generates a preamble containing: a first data field designating the first cell identity, and a second data field reflecting a respective identity of the wireless nodes in the set of wireless nodes which use the at least one overlapping communication resource. The first wireless node transmits a preamble signal containing the preamble, over a predefined set of resources in a shared resource structure of the wireless communication system thus informing about the wireless nodes that use overlapping communication resources.
