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.

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

According to certain embodiments, a method in a wireless device () includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link. In response to receiving the positive acknowledgement, the one or more retransmissions of the PDU or the segment of the PDU on the second link are cancelled.

Systems and methods for removal of duplicated packets for transmission

A radio node is configured for use in a wireless communication system. The radio node in this regard is configured to transmit a signal that is punctured by another signal to another radio node. The radio node is also configured to estimate a probability of decoding failure that characterizes a likelihood that the another radio will fail to decode the punctured signal. The radio node is further configured to retransmit at least a punctured portion of the punctured signal if the estimated probability is above a threshold.

Retransmission for punctured signals

A transmitting node determines data for a first service will be transmitted during a time period when data for a second service will be transmitted. The data for the first service requires lower latency than the data for the second service and the data for the first service includes an original set of data for the first service and at least one repetition of the original set of data for the first service. The transmitting node adjusts resources consumed by the data for the first service based on available transmission resources. During the time period the transmitting node then transmits the data for the first service using the adjusted resources while data for the second service is transmitted during the time period.

Configuring puncture bundles of data for a first service in a transmission of a second service

A method performed by a first communication device () operating in a wireless communications network (). The first communication device () obtains () a grant for an uplink transmission to a second communication device () operating in the 5 wireless communications network (). The grant comprises a first indication of one or more first sets of parameters for transmission. The first communication device () selects () a second set of parameters for the uplink transmission based on: i) the indicated one or more first sets of parameters, and ii) one or more quality of service requirements of an information to be transmitted in the uplink transmission. The first 10 communication device () then initiates () sending the uplink transmission to the second communication device (), based on the selected second set of parameters.

First communication device, second communication device, and methods performed thereby for handling uplink transmissions based on quality of service requirements

A receiver blindly determines which parts of the soft buffer to flush by comparing the reception of a first transmission to the reception of a second transmission (i.e., a re-transmission of the first transmission). Any large differences between the first and second transmissions are identified as puncturing events. After identifying the location of the puncturing events, the receiver then evaluates different hypotheses about which one of the transmissions was punctured in the different events. For each of the hypotheses the receiver attempts to decode the received data and the receiver stops processing once decoding is successful or after the receiver has processed all of the hypotheses.

Detection of punctured resources

In order to address problems arising due to conflicting transmissions of different services, each transport block transmitted to a receiver includes at least two code blocks and the decision by the receiver to flush and replace parts of the soft buffer and/or to add the soft bits to only some of the code blocks of a transport block is based on a combination of the multi-bit feedback transmitted by the receiver and a multi-bit indication in the DCI (Downlink Control Information) transmitted by the transmitter.

Enhancements for retransmission due to conflicting transmissions for different services

There is provided a method in a node for a wireless communication network. The node is configurable with a plurality of radio carriers for radio transmission between the node and one or more other nodes of the wireless communication network. The plurality of radio carriers comprises at least a first carrier and a second carrier. The node is operable according to a protocol stack comprising at least a first layer and a second layer, wherein the second layer is higher than the first layer. The first layer is responsible for aggregation of the first and second radio carriers, and the second layer is responsible for duplication of data packets for transmission over the first and second carriers. The method comprises determining, at a first entity of the first layer, that the second carrier is activated or deactivated; and sending, from the first entity of the first layer to a first entity of the second layer, an indication of the activation or deactivation of the second carrier.

Methods and nodes for packet duplication relating to carrier aggregation in a wireless communication network

According to certain embodiments a method is provided for use in a wireless transmitter that includes receiving an indication to schedule a high-priority transmission to preempt a lower-priority transmission that comprises one or more code blocks. A first resource allocation is determined for the high-priority transmission. A fraction of bits in the one or more code blocks of the lower-priority transmission that will be punctured by the first resource allocation is determined. When the fraction of bits in the one or more code blocks of the lower-priority transmission that will be punctured is less than a threshold, the first resource allocation is used for the high-priority transmission. Otherwise, a second allocation for the high-priority transmission is determined and used to minimize a number of the one or more code blocks that will be punctured.

Code block aware slot preemption

According to certain embodiments, a method in a wireless device includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link. In response to receiving the positive acknowledgement, the one or more retransmissions of the PDU or the segment of the PDU on the second link are cancelled.
