  • Patent number: 10673569
    Abstract: Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.

  • Patent number: 10645672
    Abstract: Handling of a paging extension in a wireless communication network. A terminal device in the wireless communication network receives, from a base station in the wireless communication network, a message including an indication of a paging extension for the terminal device. The terminal device is associated with a first coverage class. Based on the message, the terminal device determines a second coverage class of a downlink transmission from the base station to a further terminal device. Then, the terminal device determines a target paging group for the paging extension based on the first coverage class and the second coverage class.

  • Patent number: 10616856
    Abstract: Method by a wireless device (120) for supporting positioning of the wireless device (120) in a wireless communication network (100). The wireless device (120) receives (501, 801) from a first network node (110), a positioning request. The wireless device (120) is served in by the first network node (110) when receiving the positioning request. The positioning request requests the wireless device (120) to initiate a multilateration. In response, the wireless device (120) sends (504, 804a) to a second network node (113) comprised in the wireless communication network (100), a positioning access request indicating that the access request relates to a multilateration positioning and requesting the second network node (113) to estimate a Timing Advance (TA) for the wireless device (120). The wireless device (120) sends (505, 804a, 804c), to the second network node (113), an obtained device identifier identifying the wireless device (120), and an obtained source identifier identifying the first network node (110).

  • Publication number: 20200059885
    Abstract: Method performed by a first network node (101), e.g. a SGSN or an MME. The first network node (101) initiates sending (401) a first paging request to a second network node (102), e.g. a node of a Base Station Subsystem (BSS), which indicates that a wireless device (141) served by the second network node (102) is to initiate cell reselection prior to sending a first response, based on the first paging request, wherein the wireless device (141) is to be paged for a positioning procedure, e.g. a timing advance (TA) multilateration.
