摘要： Methods, network node (110, 800) and device (120; 1000) for managing a cell identity of a cell (115) in a GSM network (100). The device (120; 1000) receives, from the network node (110; 800), a cell identifier for identifying said cell (115), which cell identifier is a Base Station Identity Code, “BSIC”, coding an identity of said cell (115) and being formed of at least three sets of bits: A first three bits set thereof being a Network Color Code, “NCC”, a second three bits set thereof being a Base Station Color Code, “BCC”, and an additional third set thereof comprising one or more bits.

摘要： A radio access network node (e.g., Base Station Subsystem), a wireless device (e.g., a mobile station), and various methods are described herein for improving the allocation of radio resources in wireless communications. In one embodiment, the radio access network node and wireless device implement a fixed uplink allocation technique. In another embodiment, the radio access network node and wireless device implement a flexible downlink allocation technique.

摘要： Methods and arrangements for enabling contention resolution of uplink transmissions ata radio network node (120). A wireless communication device (110) sends (3010; 4010) an access request to the radio network node (120). The wireless communication device (110) receives (3040; 4040) an access grant from the radio network node (120) and then sends (3050-3110; 4050-4110), to the radio network node (120), at least two data blocks. At least two data blocks includes only one occurrence of a unique device identity and at least one occurrence of a reduced ID that is represented by fewer bits than the unique device ID.

摘要： A process allows a UE to acquire a System Frame Number (SFN) before accessing a target base station/node during a RACH-less handover. The SFN may be provided to the UE in various ways. For example, the SFN may be provided as part of a handover command message (e.g., RRCReconfiguration) or a master information block (MIB). In this manner, the UE acquires the SFN before accessing the target base station/node, which allows the target base station/node and the UE to effect certain timings for the handover. For example, the target base station/node and the UE may set time bounds in which the handover must occur. As another example, different types of uplink grants may be set.

摘要： A first network node and method therein for handling an operation mode change of a second network node for a communication device in a wireless communication network are disclosed. The communication device is configured with multi-radio dual connectivity (MR-DC) with the first network node having a first cell group and the second network node having a second cell group. The first network node receives (913) a request from the second network node for a change of operation mode and/or a change of configuration of the second network node and determines (914) whether to accept or reject the request for the change of the operation mode and/or a change of configuration. The first network node transmits (915) to the communication device a message including a reconfiguration or command to change the second cell group configuration and/or the operation mode of the second cell group, if it is determined that the change of operation mode of the second cell group and/or change of the second cell group configuration is accepted; or transmits (917) a response to the second network node with an indication indicating a rejection reason, if it is determined to reject the request for the change of the operation mode.

摘要： A method by a user equipment in a wireless communication system includes receiving an access command from a source node, the access command instructing the UE to access a target cell and including an access configuration specifying an access method without random access and one or more valid target cell beams for which the access configuration is valid at the target cell, and accessing the target cell in response to the access command.

摘要： According to some embodiments, a method for use in a user equipment of performing cell reselection to a cell providing multimedia broadcast multicast service (MBMS) comprises: receiving a system information message comprising an indication of whether one or more carrier frequencies support MBMS carrier type or further enhanced MBMS (FeMBMS) carrier type; selecting, based on a capability of the user equipment and the carrier type of the one or more carrier frequencies, a carrier frequency for cell reselection; and camping on the selected carrier frequency. In particular embodiments, the system information message further comprises, for each of the one or more carrier frequencies, an indication of a percentage (e.g., 100%, 80%, etc.) of available multicast broadcast single frequency network (MBSFN) subframes in each radio frame.

摘要： Embodiments include methods for a UE to perform mobility operations in a wireless network based on conditions related to data traffic. Such methods include receiving, from a network node, one or more conditional reconfigurations. Each includes a reconfiguration message associated with a candidate target cell and one or more execution conditions that need to be fulfilled to apply the reconfiguration message when performing a mobility operation, including at least one first execution condition related to UE data traffic and/or to one or more UE applications. Such methods include monitoring for the execution conditions in the conditional reconfigurations and based on detecting fulfillment of one or more execution conditions in a particular conditional measurement configuration, performing a mobility operation towards the candidate target cell associated with the reconfiguration message in the particular conditional measurement configuration. Other embodiments include complementary methods by a network node, as well as UEs and network nodes

摘要： Embodiments disclosed herein provide methods and apparatus for requesting system information in a wireless communications network. The method comprises in a user equipment for a wireless network receiving, from a base station of the wireless network, a first portion of system information comprising an indication of a second portion of system information which is available upon request; and transmitting, to the base station, a first request requesting that the second portion of system information be transmitted to the user equipment. The method further comprises responsive to a determination that the requested second portion of system information has not been received successfully by the user equipment, transmitting, to the base station, a second request for the second portion of system information.

摘要： A method by a wireless device is provided to perform access barring. The method includes starting (1402) a barring timer when an access attempt is barred and, based on a change in barring information (1404), the barring timer is stopped. Alleviation of access barring may be performed when the barring timer is stopped.
