摘要： The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.

摘要： 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.

摘要： The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE, when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping between each configuration and the corresponding identity of each configuration.
摘要翻译：本发明涉及使用预定义类型的标识符的方法和装置，例如， RNTI识别带外控制信道上的一个配置，用于激活由该标识符可识别的配置。当要激活与该标识符相对应的配置时，将标识符从网络发送到UE。这意味着UE和无线电基站都包括每个配置与每个配置的对应身份之间的映射。

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

摘要： A method in a wireless device is disclosed. The method comprises sending a scheduling request to a network node, and receiving, from the network node in response to the scheduling request, a grant of uplink resources. The method further comprises determining whether the granted uplink resources are at least equal to or larger than the resources required for transmission of both a buffer status report (BSR) and a sidelink BSR, and upon determining that the granted uplink resources are at least equal to or larger than the resources required for transmission of both the BSR and the sidelink BSR, communicating the BSR and the sidelink BSR to the network node in a single medium access control (MAC) protocol data unit (PDU).

摘要： The present invention relates to methods and apparatuses (radio base station and UE) for enabling a UE to perform a contention-based random access. According to embodiments of the present invention, a non-dedicated random access preamble identifier is determined by a radio base station and the determined preamble is transmitted in a message to the UE which selects a non-dedicated random access preamble based on the received preamble identifier and performs a contention-based random access using the selected preamble.
