  • Publication number: 20240039662
    Abstract: Embodiments herein relate to a method implemented by a wireless communication device. The wireless communication device transmits data to a radio node of a wireless communication network. The wireless communication device monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node. The wireless communication device retransmits the data to the radio node when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device refrains from retransmitting the data to the radio node when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device also refrains from retransmitting the data to the radio node when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.

  • Patent number: 11191015
    Abstract: In the context of “operator-controlled Wi-Fi” as in 3GPP TR 37,834 vl2,0,0 “Study on Wireless Local Area Network (WLAN)”, both in solution2 and solution3, WLAN identifiers need to be communicated between the radio access network, RAN, and the UE. However, WLAN identifiers (e. g., SSIDs, BSSIDs, ESSIDs, HESSIDs, Realm identifiers, NAIs, PLMN identifiers, Domain Name lists, . . . ) are large (e. g., SSID may be up to 32 bytes) and cause a large overhead in the wireless interface. This problem is solved by providing an indexed listing of WLAN Identifiers and by only exchanging the indices across the wireless interface; Preferably, some WLANs may have several indices, and each index may also be used to convey the action to take by the UE.

  • Publication number: 20210328750
    Abstract: According to one embodiment, a method may be provided to operate a wireless terminal in communication with a wireless communication network. A first bit map having a first bit map size is received with bits of the first bit map corresponding to respective component carriers of a first group of component carriers and indicating a status of the respective component carriers of the first group. A second bit map having a second bit map size is received with bits of the second bit map corresponding to respective component carriers of a second group of component carriers and indicating a status of the respective component carriers of the second group. Moreover, the first bit map size of the first bit map is different than the second bit map size of the second bit map.

  • Patent number: 10939368
    Abstract: A method in a terminal for inter RAT access selection is provided. The terminal is capable to operate in one or more RATs. The terminal receives (201) (202), from a network node, one or more dedicated parameters relating to inter RAT access selection, and one or more broadcasted parameters relating to inter RAT access selection. The one or more broadcasted parameters correspond to the respective one or more dedicated parameters. The one or more broadcasted parameters relates to inter RAT access selection. The terminal then acts (203) for inter RAT access selection according to any one out of: —one or more updated dedicated parameters, updated based on changes to corresponding one or more broadcast parameters, and—any one out of the one or more received dedicated parameters, updated dedicated parameters, or corresponding broadcasted parameters, based on whether one or more conditions are fulfilled or not.
