摘要： Apparatus and methods are provided for a wireless device and an access node connected with each other over a wireless connection that has a configured packet delay budget and that transports a packet flow established between the wireless device and another device. In response to determining that the packet delay budget of the wireless connection should be adjusted based on end-to-end packet delay measurement performed by the wireless device communication, the wireless device sends an adjustment indication to the access node, where the adjustment indication includes an adjustment value to be applied by the access node in order to change the packet delay budget of the wireless connection. The adjustment value is provided for power saving operation or coverage enhancement of the wireless device.

摘要： Systems and methods avoid the need to coordinate preambles between UEs performing random access on their PCells and SCells. According to an embodiment, a method for random access in a radio communication system includes: transmitting, by a network node, a random access response including a Radio Network Temporary Identifier (RNTI) which has a first value if the random access is associated with a first cell and a second value if the random access is associated with a second cell, the first value being different than the second value and the first cell being different from the second cell.

摘要： A method in a user equipment for adjusting a transmit timing of uplink transmissions to a network node in a telecommunications system is provided. The user equipment is configurable with more than one aggregated serving cells. The reception timing of a downlink transmission from a timing reference serving cell is used as a timing reference for the transmit timing of uplink transmissions. The user equipment determines a change to a second serving cell as the new timing reference serving cell which is different from a first serving cell currently being used as the timing reference serving cell. The user equipment applies an incremental adjustment of the transmit timing of uplink transmissions for the serving cells in a group of serving cells with respect to a timing reference based on the reception timing of a downlink transmission from the second serving cell in the user equipment.

摘要： In a method for assigning serving cells of a mobile terminal to timing advance groups, a network node transmits a Medium Access Control (MAC) control element to a mobile terminal in a wireless communication network. The MAC control element includes a set of first indicators, with each first indicator specifying whether a corresponding serving cell of the mobile terminal is to be included in a timing advance group. The MAC control element also includes at least one second indicator, with each second indicator specifying a timing advance group, and also specifying, via a defined mapping, the serving cell of the mobile terminal to which the timing advance group corresponds.

摘要： A method in a user equipment (121) for adjusting a transmit timing of uplink transmissions to a network node (110) in a telecommunications system (100) is provided. The user equipment (121) is configurable with more than one aggregated serving cells. The more than one aggregated serving cells are divided into one or more groups of serving cells based on a timing advance value of each of the aggregated serving cells. The one or more groups of serving cells each comprises a timing reference serving cell. The reception timing of a downlink transmission from a timing reference serving cell is used as a timing reference for the transmit timing of uplink transmissions for the serving cells in the group of serving cells comprising the timing reference serving cell, respectively. The user equipment (121) determines a change to a second timing reference serving cell in a group of serving cells, which second timing reference serving cell is different from a first timing reference serving cell currently being used as the timing reference serving cell for the group of serving cells. Then, the user equipment (121) applies an incremental adjustment of the transmit timing of uplink transmissions for the serving cells in the group of serving cells with respect to a timing reference based on the reception timing of a downlink transmission from the second timing reference serving cell in the user equipment (121).A user equipment, a method in network node and a network node are also provided.

摘要： Some of the example embodiments presented herein are directed towards a user equipment (501), and corresponding method therein, for uplink timing alignment. The user equipment (501) may initiate a timing advance value to zero during a creation of a timing advance group, a modification of a timing advance group, or if a TAC MAC CE command has not been performed. The user equipment (501) may further update the timing advance value based on a received TAC MAC CE command.Some of the example embodiments presented herein are directed towards a base station, and corresponding method therein, for uplink timing alignment. The base station (401) may be configured to estimate a proximity of the user equipment (501) to an uplink receive or an uplink cell size of the user equipment. The base station may determine a TAC MAC CE based on the estimation and send the TAC MAC CE to the user equipment (501) for uplink timing alignment.
摘要翻译：本文提出的一些示例性实施例针对用于上行链路定时对准的用户设备（501）及其中的相应方法。用户设备（501）可以在创建定时提前组，定时提前组的修改或者还没有执行TAC MAC CE命令时启动定时提前值为零。用户设备（501）还可以基于所接收的TAC MAC CE命令更新定时提前值。这里呈现的一些示例实施例针对基站，以及其中的相应方法，用于上行链路定时对准。基站（401）可以被配置为估计用户设备（501）与用户设备的上行链路接收或上行链路小区大小的接近度。基站可以基于估计来确定TAC MAC CE，并将TAC MAC CE发送给用户设备（501）以进行上行链路定时对准。

摘要： A method, performed in a user equipment (UE) includes: saving a timing advance (TA) value when a TA timer associated with the TA value expires, the TA value indicating when the UE should start its uplink transmission before a nominal time given by the timing of a downlink signal received by the UE; and starting the TA timer in response to the UE receiving a TA command from an evolved Node B while the TA value is saved, the TA command containing an update for the TA value. A corresponding UE is presented.
