Method and arrangement in a base station for providing feedback to user equipments in a cell concerning the reception status of data received from the user equipments. The base station and the user equipments are comprised in a wireless communication system, adapted for contention based transmissions. The method comprises sending a contention based grant to a plurality of user equipments within the cell, receiving data from any user equipment and verifying if the data is correctly received. Also, the method comprises sending feedback to any user equipment that has used the contention based grant, wherein the feedback comprises an ACK, if it is verified that data has been correctly received from at least one user equipment and the feedback comprises a NACK if it is verified that data has not been correctly received from any user equipment. Also, a corresponding method and arrangement in a user equipment is described.

method and an arrangement (800) in a radio network node (140) for sharing of a first Cell Radio Network Temporary Identifier, referred to as “C-RNTI” between at least a first and a second communication device (110, 120) are provided. The radio network node (140) receives a first random access preamble from the first communication device (110). Furthermore, the radio network node (140) associates the first C-RNTI to the first communication device (110), in response to the first random access preamble. The radio network node (140) receives a second random access preamble from the second communication device (120). Moreover, the radio network node (140) associates the first C-RNTI to the second communication device (120), in response to the second random access preamble, while the association of the first C-RNTI to the first communication device (110) is maintained. A method and an arrangement (900) in a first communication device (110) for enabling sharing of a first Cell Radio Network Temporary Identifier between at least the first communication device (110) and a second communication device (120) are provided.

摘要:
The mobile station described herein comprises a transmission buffer, a receiver, a transmitter, and a controller. The controller triggers a scheduling request and buffer status report when data enters the transmission buffer. When the receiver receives a contention-based scheduling grant allocating contention-based uplink resources, the transmitter transmits one or more data packets retrieved from the transmission buffer along with the buffer status report on the contention-based resources to the network station. If one or more data packets remain in the transmission buffer after transmission of the buffer status report on the contention-based resources, the controller maintains the pending status of the buffer status report and the corresponding scheduling request.
摘要:
The present invention provides methods and apparatus for selectively notifying user equipments (UEs) of updated access barring statuses and for spreading access attempts by the UEs. The methods and apparatus disclosed in the present application reduce potential overloads in a radio access network caused by UEs simultaneously accessing the radio network, after being notified that access restrictions have been removed.

摘要:
A method implemented at a user equipment (UE) may include receiving a grant from a base station permitting the user equipment to transmit data to the base station and transmitting data to the base station, where the data includes a buffer status report (BSR) that indicates an amount of data in a buffer of the UE. The method may further include starting or restarting a discontinuous reception (DRX) timer when the data including the BSR is transmitted to the base station. The method may additionally include monitoring (730) a control channel during a duration of the DRX timer. In another implementation, a method may include receiving a feedback message in response to the data transmission including the BSR, and starting or restarting the discontinuous reception (DRX) timer when the feedback message is received. The feedback message may include an acknowledgement (ACK) or a negative acknowledgement (NACK). In a further implementation, a method may include starting a process specific hybrid automatic repeat request (HARQ) round trip time (RTT) timer upon transmission of the data including the BSR, starting a grant timer when the HARQ RTT timer expires, and monitoring the control channel during a duration of the grant timer.
摘要:
The access of a user equipment, UE, (10) configured for and activated to implement extended access barring, EAB, or included in a group of UEs addressed via group paging to a wireless communication network (20) is controlled. First, an access delay for the UE is determined. Second, a timing of an attempt by the UE to access a cell in the wireless communication network is controlled based on the determined access delay. Many example embodiments are described.
