Abstract: Techniques for improved scheduling request (SR) operation using one or more short transmission time intervals (sTTIs) (908) are presented to ensure both short latency and improved wireless coverage for user equipment (UE) (102). In particular, a method (1000) performed by a UE (102) for managing SR transmissions to a network node (106) is presented. The method can include determining (1002) a value indicative of network coverage conditions, and based on the value indicative of network coverage conditions, determining (1004) a transmission duration (908) for transmitting one or more SRs (118). In addition, the example method can include transmitting (1006) the one or more SRs (118) to the network node (106) using the determined transmission duration (908). Related devices, computer programs, processor/memory combinations, and systems are likewise described.

Abstract: Certain embodiments relate to a method for use in a wireless device. The method comprises distributing uplink power among parallel transmissions that the wireless device has scheduled during a subframe on two or more uplink physical channels. The parallel transmissions comprise one or more short transmission time interval, sTTI, transmissions, and the UL power is distributed according to at least one prioritization rule. According to one of the prioritization rules, sTTI transmissions comprising control information are prioritized over sTTI transmissions comprising data without any control information. According to another of the prioritization rules, transmissions with shorter transmission time intervals are prioritized over transmissions with longer transmission time intervals.

Abstract: A sending node (120; 110) sends information to a receiving node (110; 120). Said nodes are comprised in a wireless communication network (100). Communication between said nodes is associated with a first cell (115). The sending node (120; 110) obtains (601; 701) predefined scrambling for scrambling the information and which predefined scrambling is specific for the first cell (115). The receiving node correspondingly obtains de-scrambling. The sending node (120; 110) sends, to the receiving node (110; 120), the information repeatedly a certain number of times, wherein each time the information is sent it is scrambled differently based on the obtained scrambling. Each time the information is received by the receiving node (110; 120) it is de-scrambled differently based on the obtained de-scrambling.

Abstract: A method (500) is performed by a wireless device (710). The method comprises transmitting (540) an uplink signal (730). A time offset (820) is employed for the uplink signal. The time offset is based on an estimated filter delay (812, 813, 814, 815) and an estimated distance between the wireless device and a network node (720). The estimated filter delay is associated with one or more filters (712, 714, 722, 724) of the wireless device and/or of the network node. In some embodiments, the time offset is also based on an estimated radio channel delay (816) of a radio channel between the wireless device and the network node relative to the delay of a line of sight, LOS, path between the wireless device and the network node. In some embodiments, the wireless device receives an indication (760) that the wireless device is to determine the time offset.
