In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including low-latency traffic, first control information, and second control information. The low-latency traffic may be traffic which requires latency less than or equal to a threshold value. The first control information may include information associated with the size of the low-latency traffic stored in a buffer and the size of other traffic than the low-latency traffic, stored in the buffer. The second control information may include information associated with the low-latency traffic. The STA may be allocated a resource for the low-latency traffic. The STA may transmit a second PPDU through the resource.

A method according to an embodiment of the present application includes: mapping at least one data packet to a QoS flow, wherein the QoS flow is associated with a set of QoS parameters; mapping the QoS flow to a sidelink radio bearer (SLRB) based on index configuration information, wherein the index configuration information indicates a set of indexes associated with each QoS parameter of the set of QoS parameters; and transmitting configuration information of the SLRB and mapping index information, wherein the mapping index information indicates a quantization index of each QoS parameter of the set of QoS parameters, and the set of QoS parameters is quantified to the mapping index information based on the index configuration information.

A method, a system, and a computer program product for selecting fronthaul links in a wireless communication system. One or more link delays are determined. The link delays are associated with one or more communication links in the plurality of communication links communicatively coupling a first communication device and a second communication device. Using the determined link delays, a communication link transmission priority of the communication links for transmission of one or more data packets is determined. A listing of prioritized communication links is generated. At least one communication link in the prioritized communication links is selected for transmission of data packets between the first and second communication devices. Using the selected communication link, the data packets are transmitted between the first and second communication devices.

The RIC may include: an application, a plurality of E2 terminations connected between the at least one node and the application, and a traffic controller. The traffic controller may be configured to: receive a subscription request for the node from the application, select an E2 termination to be used for the application to perform subscription among the plurality of E2 terminations based on traffic information of data transmitted or received through the E2 termination, and control the application to receive data through the E2 node, through the selected E2 termination.

The present application relates to a method for indicating an antenna switching capability, a terminal device and a communication device, where the method includes: sending, by a first terminal device, a first UE capability, where the first UE capability indicates at least one antenna switching capability supported by the first terminal device; at least part of the at least one antenna switching capability supports that the first terminal device has more than 4 receiving antennas. Embodiments of the present application can achieve indication of an antenna switching capability for a terminal device with more (such as more than 4) receiving antennas.

A method, computer program product, and computer system for transmitting an ACK in response to receipt of a data packet in RLC AM mode operation in a 5G communication protocol stack. A first RLC entity receives from a receiving UE corresponding to the first RLC entity: (i) an ACK to be sent to a transmitting UE in response to the receiving UE having received a data packet from the transmitting UE and (ii) a first RLC channel extracted by the receiving UE from a header of the data packet. In response to a first communication having specified that the first RLC channel is congested, the first RLC entity selects a second, different RLC channel operating in the RLC AM mode and not being congested. The first RLC entity sends the ACK to the transmitting UE via the second RLC channel instead of via the first RLC channel.

A method and an apparatus are provided for managing quality of service (QoS) in a communication network. A plurality of data flows related to at least one application associated with a user equipment (UE) is received. At least one data flow that requires QoS management related to the at least one application is identified from the plurality of data flows based on an analysis of at least one of a plurality of attributes related to the at least one application. The at least one data flow is classified into a QoS class associated with the at least one application. The at least one data flow is prioritized based on the QoS class.

A computer implemented system is provided for improving performance of transmission in real-time or near real-time applications from at least one transmitter unit to at least one receiver unit. The system includes an intelligent data connection manager utility that generates or accesses performance data for two or more data connections associated with the two or more communication networks, and based on the current performance data determining current network transmission characteristics associated the two or more data connections, and bonds the two or more data connections based on: a predetermined system latency requirement; and dynamically allocating different functions associated with data transmission between the two or more data connections based on their respective current network transmission characteristics. The data connection manager utility then manages dynamically the transmission of relatively large data sets across the two or more bonded or aggregated data connections in a way that meets the system latency requirement and improves performance in regards to other network performance criteria (including data transfer rate, errors, and/or packet loss). Related computer implemented methods are also provided.
