摘要： The present invention relates to methods and apparatuses (radio base station) and UE for enabling a UE to perform a random access. According to embodiments of the present invention, an identification number of a dedicated random access preamble is, in a message, transmitted together with information indicating in which channel or channels the preamble is valid for the UE. The UE can then use the received information and based on that information perform a random access.

摘要： This disclosure relates to methods and apparatuses for In-Device Coexistence (IDC) indication. Among other things, the present disclosure presents a method performed by a user equipment (UE). The UE is configured to send 201 an IDC indication message with a same content as in a previously sent IDC indication message if, or when, the UE has performed a handover to another cell (target cell).

摘要： Systems and methods for generating and decoding messages including header extensions are provided. It can be determined that a header extension is required for signaling a LCID value. A MAC sub-header including an indicator that the LCID value is extended can be generated and transmitted. A received message including a header extension can be decoded appropriately.

摘要： According to certain embodiments, a method (400) by user equipment (UE) (300) is provided for avoiding bearer state mismatch that includes storing, by the UE, a passive context for use in resuming a connection with a network node (600). While the UE is in an inactive state, the UE locally deactivates at least one radio bearer. The UE signals, to the network node, an indication that the at least one radio bearer has been deactivated locally and the network node consequently modifies the stored bearer context.

摘要： According to one embodiment, a method of operating a wireless terminal may include configuring a first group of component carriers, and while configured with the first group of component carriers, communicating a first MAC CE including a first bit map having a first bit map size with bits of the first bit map corresponding to respective component carriers of the first group of component carriers. The method may also include configuring a second group of component carriers wherein the first and second groups of component carriers are different. While configured with the second group of component carriers, a second MAC CE may be communicated, wherein the second MAC CE includes a second bit map having a second bit map size with bits of the second bit map corresponding to respective component carriers of the second group of component carriers. Moreover, the first and second bit map sizes may be different.

摘要： The present invention relates to methods and apparatuses (radio base station (120, 600) and UE (110, 700) for enabling a UE to perform a random access. According to embodiments of the present invention, an identification number of a dedicated random access preamble is, in a message, transmitted together with information indicating in which channel or channels the preamble is valid for the UE. The UE (110, 700) can then use the received information and based on that information perform a random access.

摘要： A basestation in a cellular communications network is operable to send a message to a Mobility Management Entity, relating to a suspension or resumption of a connection of a UE, wherein the message contains key renewal information. The Mobility Management Entity receives the message, and determines whether a key renewal condition is met. If the key renewal condition is met, the MME forwards a new NH, NCC pair to the base station. If a message received from the MME includes a NH, NCC pair, the basestation derives keying information using the NH, NCC pair for future use in deriving keys.

摘要： A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

摘要： A method of managing an access attempt for accessing a cellular network (82) is described. The method is performed by a communication device (40) and comprises sending (84), to a radio network node (60) of the cellular network (82), an access request message for requesting access to the cellular network (82), and receiving (88), from the radio network node (60), an access response message for the access request message. The access response message comprises a wait indication indicating to wait for a resumption indication before resuming the access attempt. The resumption indication indicates to resume the access attempt, and the method also comprises, in response to the received wait indication, waiting (90) to resume the access attempt. The communication device (40) is in an idle mode and the access response message is received after a random access response message. Alternatively, the communication device (40) is in a connected mode and the resumption indication is received via a physical downlink control channel. Therefore load control of load associated with the access attempt of the communication device (40) may be accomplished in a fast, easy and flexible way.
