Abstract: The present disclosure provides a mechanism enabling switching between different configuration for a positioning procedure to dynamically adapt the accuracy of the positioning procedure to the current requirements of client devices and/or environmental conditions. The switch may be initiated by a network node which can instruct a client device to deactivate positioning according to a first configuration and to activate positioning according to a second configuration. The network node can determine the second configuration based on e.g. position of client device, density of client devices, current position requirements per client device, network load, and/or available resources. Thereby, allowing the configuration for the positioning procedure to be adapted based on dynamic requirements on the positioning procedure.

Abstract: The invention provides a mechanism for switching between a first and a second positioning procedure. The first positioning procedure may be an absolute positioning procedure and the second positioning may be a relative positioning procedure. The switch may be initiated by a network node (300) which can instruct a client device (100) to terminate the first positioning procedure and to activate the second positioning procedure or to instruct the client device (100) to continue with the first positioning procedure and to activate the second positioning procedure. Thereby, allowing the positioning procedure used by the client device (100) to be adapted e.g. based on dynamic requirements on positioning procedures set by applications.

Abstract: A first client device compresses a broadcast sidelink packet according to a configuration for a compression profile by removing at least one non-IP header of the broadcast sidelink packet. The first client device transmits the compressed broadcast sidelink packet together with an indication of the compression profile. When a second client device receives the compressed broadcast sidelink packet, the second client device reconstructs the at least one non-IP header of the broadcast sidelink packet based on the configuration for the compression profile and the indicated compression profile.

Abstract: The present disclosure relates to a network access node and a client device for content type indication. The network access node selects a subset of bits among a set of bits in a second data packet associated with the first data packet based on the content type for the first data packet. The network access node scrambles the selected subset of bits with a first scrambling sequence associated with an identity of the client device. The network access node transmits the first data packet and the second data packet to the client device (300). Upon reception of the first data packet and the second data packet, the client device descrambles the scrambled subset of bits in the second data packet using a first scrambling sequence associated with an identity of the client device to determine the content type for the first data packet.

Abstract: The application relates to maintaining time-synchronization of a wireless connection between a network access node and a client device. The wireless connection may be configured for services with latency constraints. In one example, based on an expiry of a time alignment timer for the client device, the network access node transmits a control message to the client device. The control message instructs the client device to transmit a response signal to the network access node. The response signal can be used by the network access node to determine the timing advance for the wireless connection and adjust the timing advance.

Abstract: The invention relates to power control in groupcast communication between a first communication device (100) and a set of second communication devices (300a, 300b, . . . , 300n). The first communication device (100) obtains received signal qualities from a reporting subset (300a?, 300b?, . . . , 300n?) in the set of second communication devices (300a, 300b, . . . , 300n) and determines at least one path loss value for the reporting subset (300a?, 300b?, . . . , 300n?) based on the one or more obtained received signal qualities. The first communication device (100) may further determine a transmission power value for the groupcast communication based on the at least one path loss value and perform a groupcast communication transmission based on the determined transmission power value. Furthermore, the invention also relates to a second communication device (300), corresponding methods, and a computer program.

Abstract: The invention relates to detecting and indicating that a QoS estimate for a radio link serving an application does not fulfill a QoS requirement associated with the application. A client device monitors QoS estimates for a radio link serving an application in the physical layer. The monitoring is based on a QoS monitoring configuration associated with the application. Upon detecting that a QoS estimate does not fulfill a QoS requirement obtained from the QoS monitoring configuration, the client device provides a first indication to a second layer arranged above the physical layer. The first indication provides an early warning that the radio link does not fulfill the QoS requirement. Thereby, allowing the client device to take precautionary actions to counteract possible negative consequences of the non-fulfillment of the QoS requirement. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: The invention relates to detection and indication of non-fulfillment of latency requirements of uplink data packets associated with an application. A client device monitors transmissions of uplink data packets associated with the application, in a first layer, for non-fulfillment of latency requirements of the uplink data packets. The monitoring is based on a QoS monitoring configuration. Upon detection of a non-fulfillment of a latency requirement, the client device provides a first indication to a second layer. The first indication provides an early warning about non-fulfillment of latency requirements of uplink data packets. Thereby, allowing the client device to take precautionary actions to counteract possible negative consequences of the non-fulfillment of latency requirements. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: The disclosure relates to early detection and indication of a Quality-of-Service (QoS) non-fulfillment in one or more radio links serving an application. A client device monitors for a QoS non-fulfillment in the one or more radio links based on a QoS monitoring configuration associated with the application. The QoS monitoring configuration may be received from a network node and/or derived based on a predefined rule. Upon detection of a QoS non-fulfillment of one or more QoS requirements obtained from the QoS monitoring configuration, the client device provides a QoS non-fulfillment indication to the application. The QoS non-fulfillment indication gives the application an early warning about QoS non-fulfillment on the one or more radio links. Thereby, allowing the application to take precautionary actions to counteract possible negative consequences of the QoS non-fulfillment. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: The invention relates to a network access node (100) and a client device (300) for content type indication. The network access node selects a subset of bits among a set of bits in a second data packet 504 associated with the first data packet (502) based on the content type for the first data packet (502). The selected subset of bits is scrambled with a first scrambling sequence associated with an identity of the client device (300). The first data packet (502) and the second data packet (504) is transmitted to the client device (300). Upon reception of the first data packet (502) and the second data packet (504) the client device (300) descrambles the scrambled subset of bits in the second data packet (504) using a first scrambling sequence associated with an identity of the client device (300) to determine the content type for the first data packet (502).

Abstract: There is provided mechanisms for determining Universal Terrestrial Radio Access (UTRA) environment for a wireless terminal (WT). The WT supports operation in both a UTRA frequency-division duplexing (UTRA-FDD) environment and a UTRA time-division duplexing (UTRA-TDD) environment. The WT acquires a need for determining its UTRA environment. The WT determines its UTRA environment based on network information received by the WT. The network information indicates if the WT is in the UTRA-FDD environment or in the UTRA-TDD environment.

Abstract: A decoding-reliability metric from a received-signal decoder is compared with a threshold to decrease significantly the probability of false detection in a receiver and thus increase communication reliability and performance. In a wideband code division multiple access communication system, for example, significant decrease of the probability of false grant-message detection and significant increases of enhanced uplink performance and reliability can be obtained.
