Abstract
Embodiments herein relate to a wireless device (10) for handling communication of the wireless device (10) in a wireless communication network (1), wherein a radio network node (12) in the wireless communication network (1) provides radio coverage over a cell. The wireless device receives from the radio network node (12), when the wireless device (10) is in a first state, a beam configuration indicating which beam or beams of the cell the wireless device (10) is allowed to select during a state transition or initial access. Furthermore, the wireless device performs an initial access to the cell or a state transition taking the beam configuration into account.
Claims16
A method performed by a wireless device for handling communication of the wireless device in a wireless communication network, wherein a radio network node in the wireless communication network provides radio coverage over a cell, the method comprising:
- receiving from the radio network node, when the wireless device is in a first state, a beam configuration indicating which beam or beams of the cell the wireless device is allowed to select during a state transition with respect to the cell or initial access to the cell;
- performing an initial access to the cell or a state transition from the first state to an active state with respect to the cell, taking the beam configuration into account;
- and
- receiving, from the radio network node, a rejection indication rejecting the initial access or the state transition, with additional information on how to access the cell again.
A method performed by a radio network node for handling communication of a wireless device in a wireless communication network, wherein the radio network node provides radio coverage over a cell in the wireless communication network, the method comprising
- transmitting to the wireless device, when the wireless device is in a first state, a beam configuration indicating which beam or beams the wireless device is allowed to select during an initial access to the cell or a state transition from the first state to an active state with respect to the cell,
- wherein the beam configuration comprises at least one of the following, whereby the beam configuration indicates which beam or beams of the cell the wireless device is allowed to select during the state transition or the initial access:
- a threshold value of strength or quality, a list of not wanted beams, a list of preferred beams, a list of allowed beams, and a list of non-allowed beams.
A wireless device for handling communication of the wireless device in a wireless communication network, wherein a radio network node in the wireless communication network is configured to provide radio coverage over a cell, wherein the wireless device comprises processing circuitry for handling communication in a wireless communication network, and wherein the processing circuitry is configured to:
- receive from the radio network node, when the wireless device is in a first state, a beam configuration indicating which beam or beams of the cell the wireless device is allowed to select during a state transition with respect to the cell or initial access to the cell;
- and
- perform an initial access to the cell or a state transition to an active state with respect to the cell, taking the beam configuration into account;
- and
- receive, from the radio network node, a rejection indication rejecting the initial access or the state transition, with additional information on how to access the cell again.
A radio network node for handling communication of a wireless device in a wireless communication network, wherein the radio network node is configured to provide radio coverage over a cell in the wireless communication network, wherein the radio network node comprises processing circuitry, and wherein the processing circuit is configured to:
- transmit to the wireless device, when the wireless device is in a first state, a beam configuration indicating which beam or beams the wireless device is allowed to select during an initial access to the cell or a state transition from the first state to an active state with respect to the cell,
- wherein the beam configuration comprises at least one of the following, whereby the beam configuration indicates which beam or beams of the cell the wireless device is allowed to select during the state transition or the initial access:
- a threshold value of strength or quality, a list of not wanted beams, a list of preferred beams, a list of allowed beams, and a list of non-allowed beams.
