According to some embodiments, a method in a wireless device comprises: receiving a control channel (e.g., physical downlink control channel (PDCCH)) that includes control information that indicates a set of time and frequency resources allocated for the wireless device to receive a data transmission; determining that the set of time and frequency resources allocated for data transmission overlaps with a control resource region (e.g., control resource set (CORESET)); and receiving the data transmission in the set of time and frequency resources allocated for data transmission. The control information may include a bitmap that indicates at one or more groups of time and frequency resources excluded/included for the data transmission region.

Data transmissions in control regions

There is disclosed a user equipment for a Radio Access Network. The user equipment is adapted for communicating utilizing a first transmission timing structure having a first number of symbols, and for communicating utilizing a second transmission timing structure comprising a second number of symbols. The user equipment further is adapted for receiving first signaling based on the first transmission timing structure and for transmitting acknowledgement signaling pertaining to the first signaling based on the second transmission timing structure, wherein the user equipment is adapted to start transmitting the acknowledgement signaling at a starting symbol of the second transmission timing structure, the starting symbol being determined based on a configuration of the user equipment.

PUCCH structure for mixed numerology

With multiple connections () communicatively coupling a User Equipment (UE) () to a wireless communication network (), methods and apparatuses disclosed for performing flow control at the Radio Link Control (RLC) level advantageously control the shares of overall data conveyed on the respective connections () in a manner that accounts for changing conditions on the involved radio links () while accommodating signaling delays and other complexities that arise from distributed or virtualized implementations of the underlying processing apparatuses (). The disclosed methods and apparatuses have applicability both to uplink multi-connectivity and downlink multi-connectivity, and apply to various multi-connectivity scenarios, including scenarios involving mixed Radio Access Technologies (RATs) and Carrier Aggregation (CA) configurations that aggregate two or more Component Carriers (CCs) for carrying user traffic between a UE () and the network ().

Method and apparatus for multi-connection flow control in a wireless communication network

A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

Detecting cellular network bottlenecks using data allocation patterns

The present invention relates to a method and apparatus for requesting scheduling of resources to be used for uplink communication of data in a communications system. If the repeated transmission by a user equipment of scheduling requests on an uplink control channel is determined to be unsuccessful, a random access transmission on a random access channel is initiated as a fallback procedure.

Systems and method for limiting the number of scheduling requests

The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.

Identifying new radio coverage availability in non-standalone mode

A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.

Detecting cellular network bottlenecks through analysis of resource allocation patterns

In one aspect, a network (e.g., a TRP) () uses handover triggering information to detect whether a handover triggering condition is present before a radio link fails, and initiates a handover upon detecting the handover triggering condition. In another aspect, a target TRP () is provided with beam generating information that enables the target TRP () to produce a high-gain beam for use in communicating with a UE () without having to perform a beam refinement procedure.

High-gain beam handover

Embodiments herein relate to a method performed by a radio network node () in a RAN for scheduling DL data for a UE () in a control region subset (). The UE () has one or more control resource sets (CORESETs) () configured in a control region (), in which CORESET () the UE () should monitor for (PDCCH). The method comprises determining to transmit DL data to the UE () in the control region subset, when the amount of DL data for the UE () is less or equal to a threshold. Embodiments herein further relate to a radio network node () in a RAN, for scheduling DL data for a UE () in a control region subset (). The radio network node () is configured to perform the method for scheduling DL data in a control region subset ().

Method and radio network node for scheduling data in control region

It is provided a method performed in a network node of a cellular network also comprising a wireless device, the wireless device being in a discontinuous reception mode comprising receiving periods and idle periods. The method comprises the steps of: transmitting a first control signal to the wireless device during a receiving period for the wireless device; determining that a first control signal is likely to have failed to be correctly received by the wireless device; determining that a second control signal needs to be transmitted to the wireless device, the second control signal corresponding to the first control signal; applying a more robust transmission procedure for the second control signal compared to a corresponding transmission procedure for the first control signal; and transmitting the second control signal to the wireless device.

Applying more robust transmission procedure

A second device that is in communication with a first device receives transmissions of the first device and detects a SILENCE period status of the first device, which corresponds to a status wherein the first device has no speech samples to be transmitted towards the second apparatus. The second device determines the type of the received transmissions, counts the number of received transmissions of a first type, and times a time interval between the last received transmission of the first type and the last received transmission of a second determined type. At reception of a transmission of the first type, the second device detects whether the first device is in the SILENCE period status on an evaluation of the counted number of transmissions of the first type and the time interval of the last received transmission of the first type and the last received transmission of the second type.

Method, system and device for detecting a silence period status in a user equipment

A method for radio communication between a transmitting node and receiving nodes comprises obtaining (S) of directions from the transmitting node to the receiving nodes and antenna gains needed for each direction. A beam forming solution having a high gain in the directions of a set of receiving nodes and with antenna gains adapted to the need of the link is obtained (S). User data to be transmitted to the receiving nodes is obtained (S). The user data is overlay-coded (S) by a code-domain overlaid code and/or a frequency-domain overlaid code, separately for each respective receiving node. The overlaid-coded user data is combined (S) into at least one combined signal stream. Analogue beamforming, hybrid beamforming or constrained beamforming is performed (S) on the combined signal stream(s) according to the beam forming solution. The beamformed data is transmitted (S) from the transmitting node to the receiving nodes.
