  • Wireless device, network node, and methods performed thereby, for handling a random access procedure
    Patent number: 12096489
    Abstract: A method performed by a wireless device. The method may be understood to be for handling a random access procedure in a wireless communications network via a network node. The wireless device operates in the wireless communications network. The wireless device refrains, after having sent a first message to the network node requesting random access and having received a first random access response message from the network node, from stopping a timer. The timer is for a time window for receiving the random access response message. The wireless device also continues monitoring both: a) a radio channel for further random access response messages from the network node addressed to a temporary identifier, and b) the radio channel, addressed to a temporary identifier specifically addressing the wireless device.

  • Signalling channel access parameters for uplink transmissions
    Patent number: 12082254
    Abstract: A wireless device (30) receives control information (28) that jointly encodes respective values for two or more channel access parameters. The two or more channel access parameters govern performance by the wireless device (30) of a listen-before-talk, LBT, procedure prior to an uplink transmission (32) in a radio resource allocation (34). In some embodiments, a mapping (40) maps different indices to different combinations of values for the two or more channel access parameters. In this case, the control information (28) may comprise an index mapped by the mapping (40) to one of the different combinations of values for the two or more channel access parameters. Regardless, the wireless device (30) may perform the LBT procedure (or not) according to the received control information (28).

  • Conditional handover execution probability information to potential target node
    Patent number: 12082061
    Abstract: According to an aspect, a source node determines (1002) that a UE served by the source node is a candidate for conditional handover configuration. The source node sends (1004), to a target node for conditional handover of the UE, a conditional handover request that includes one or more parameters indicative of a likelihood that handover of the UE to the target node will be executed. The target node receives (1102) the request and parameters and allocates (1104) resources for the UE, taking into account the likelihood that handover of the first UE to the target node will be executed. The target node sends (1106) handover configuration information for the first UE to the source node, in response to the conditional handover request.

  • Aligned configuration for random access channel-less handover/secondary cell group change
    Patent number: 12047828
    Abstract: 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.
