The disclosure pertains to determining a channel width of a channel in a wireless communication network. An aspect is directed to a device (1200, 1300) configured to determine a quality indicator for each of a plurality of channels, determine, from the plurality of channels, a first subset of channels, the quality indicators of which meeting a first requirement, combine at least two adjacent channels of the first subset of channels to a combined channel, and perform a listen before talk, LBT, operation in the combined channel. Further aspects of the disclosure pertain to a further device for determining a channel width of a channel used in a wireless communication network, methods (1100, 1700), computer programs, and computer-readable recording media.

A source node identifies a communication interval for communication with a destination node, the communication interval comprising a control interval, a data interval disposed after the control interval, a coordination interval disposed after the data interval, and a feedback interval disposed after the coordination interval. The source node transmits one or more control signals during the control interval, transmits one or more data signals during the data interval, transmits or receiving one or more coordination signals during the coordination interval, the one or more coordination signals coordinating at least one aspect of a listen-after-talk (LAT) procedure, and listens for one or more feedback signals during the feedback interval, the one or more feedback signals indicating a status of the transmission of the one or more data signals.

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 downlink subframe, a first Orthogonal Frequency-Division Multiplexing, OFDM, transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology, where the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differing from the second subcarrier spacing. The example method further includes, in the same wireless device, receiving and processing first Layer 2 data on a first physical data channel and receiving and processing second Layer 2 data on a second physical data channel, wherein the receiving and processing of the first Layer 2 data comprises the use of soft HARQ combining and wherein the receiving and processing of the second Layer 2 data comprises no soft HARQ combining. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.

Methods performed by a wireless device, such as a user equipment, having a plurality of antennas operable for beamforming, for operating in a wireless communications network. The methods further include determining, based one or more of an estimated downlink pathloss, an estimated remaining battery life for the wireless device, and a battery consumption for the wireless device, whether a number of antennas to be used for beamforming should be increased or decreased. The methods further include increasing or decreasing the number of antennas used in beamforming for one or more subsequent transmit or receive operations.

Methods performed by a wireless device, such as a user equipment, operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.
