摘要: In a wireless communication network that implements the RRC Resume procedure, an eNB sends to a radio network device, previously connected, given a Resume ID, a paging message or Random Access Response message including an RRC Resume directive. The RRC Resume directive comprises at least an indication whether or not the radio network device should perform an RRC Resume procedure. If RRC Resume directive indicates the radio network device should not perform an RRC Resume procedure, the radio network device performs an RRC Connection procedure. If the RRC Resume directive indicates the radio network device should perform an RRC Resume procedure, it may include additional information to optimize or otherwise assist the RRC Resume procedure. In this manner, RRC Resume signaling is avoided when the eNB knows that it will not be successful, such as if a prior RRC connection context is not available or readily retrievable, or is invalid.

摘要: The present disclosure generally relates to the field of Radio Resource Control (RRC). More specifically, the present disclosure relates to techniques of supporting and initiating RRC connection establishment in a wireless communication network. A method embodiment relates to supporting RRC connection establishment in a wireless communication network and comprises setting up context information during a first RRC connection establishment procedure to establish a first RRC connection towards a radio access network element (200) of the wireless communication network implementing a first Radio Access Technology (RAT). The context information is associated with a wireless communication device (100) of the wireless communication network and is usable for a second RRC connection establishment procedure to establish a second RRC connection towards a radio access network element of the wireless communication network implementing a second RAT.

摘要: A method performed by a User Equipment (UE) for handling Radio Link Failure (RLF) in a wireless communications network is provided. The UE reactivates (602) a deactivated first Secondary Cell (SCell) when an RLF over a Primary Cell (PCell) is detected. The UE further sends (603) an indication to a network node, via the reactivated SCell. The indication indicates any one or more out of the RLF over the PCell or the reactivated first SCell.

摘要: A method performed by a User Equipment (UE) for handling multiple Secondary Cell Group (SCG) configurations in a wireless communications network is provided.
The UE receives (1201) from a network node:
a first SCG configuration of a first Secondary Node, SN, and an indication of whether or not the first SCG is to be configured as active or inactive, and
a second SCG configuration of a second SN, and an indication of whether or not the second SCG is to be configured as active or inactive. The multiple SCG configurations comprises at least the first SCG configuration and the second SCG configuration.
The UE then decides (1202) whether to handle each respective SCG configuration out of the multiple SCG configurations according to a first option or a second option based on its respective indication.
The first option comprises when one or more out of the respective multiple SCG configurations are indicated to be configured as inactive, storing (1203) that particular SCG configuration.
The second option comprises when one or more out of the respective multiple SCG configurations are indicated to be configured as active, activating (1204) that particular SCG configuration in the UE.-

摘要: Certain embodiments disclose a method in a network node. The method broadcasts a location of a time and/or frequency resource of a first Physical Random Access Channel (PRACH). The first PRACH has a static location. The method determines a location of a time and/or frequency resource for a second PRACH. The location of the second PRACH is determined dynamically. The method communicates downlink control information to a wireless device. The downlink control information indicates the location of the second PRACH. The method receives a random access attempt from the wireless device. The random access attempt is received via the first PRACH or the second PRACH. The method communicates a random access response to the wireless device.

摘要: A network node (200), a wireless device (202) and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node (200) registers the wireless device (202) for contention based uplink transmissions of data on a radio resource reserved for contention based uplink transmissions of data, e.g. when receiving a registration request sent from the wireless device, such that the wireless device (202) is included in a set (200a) of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node (200) then performs blind decoding of uplink signals transmitted on the radio resource by considering the wireless devices in the set. In this way, the decoding is made more efficient by disregarding any other wireless devices in the cell which are not registered for contention based uplink transmissions of data on the radio resource in the cell.

摘要: A wireless device (202) is assisted by an access point (200) to perform contention based access on a radio channel for uplink transmission to the access point (200). The access point (200) obtains (2:1) a traffic load L on the radio channel and determines (2:2) a sleep window based on the traffic load L so that the sleep window increases when the traffic load L increases. The access point (200) then signals (2:3) the sleep window to the wireless device to instruct the wireless device to apply (2:4b) sleep mode according to the sleep window when the wireless device senses (2:4a) that the radio channel is busy. Thereby, the risk for congestion on the radio channel can be reduced during high traffic load and the energy consumption can also be reduced in the wireless device.

摘要: A method and a first node for handling a feedback procedure requiring transmission of feedback messages indicating either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted on a forward link in a radio communication with a second node in a radio network. The first node obtains a latency requirement of the radio communication corresponding to the time from transmission of the data until the data becomes outdated. The first node further applies a first transmission mode employing said feedback procedure when the latency requirement is above a latency threshold, and applies a second transmission mode omitting said feed back procedure when the latency requirement is below the latency threshold.
