Abstract
Certain aspects of the present disclosure provide techniques for performing relay reselection and releasing unicast links between relay UEs and remote UEs separately from each other. An example method generally includes taking one or more actions to trigger a relay reselection procedure separately from releasing a unicast link between the UE and a first relay UE; establishing a unicast link between the UE and a second relay UE; and releasing the unicast link between the UE and the first relay UE.
Claims57
A method for wireless communications by a user equipment (UE), comprising:
- taking one or more actions to trigger a relay reselection procedure separately from releasing a unicast link between the UE and a first relay UE, wherein:
- taking one or more actions to trigger relay reselection comprises exchanging, via the unicast link between the UE and the first relay UE, relay reselection request and relay reselection response messages that trigger the relay reselection procedure;
- and
- the relay reselection response message indicates whether the relay reselection request was accepted;
- establishing a unicast link between the UE and a second relay UE;
- and
- releasing the unicast link between the UE and the first relay UE, wherein an order in which the releasing the unicast link between the UE and the first relay UE and the relay reselection procedure is performed is at least one of:
- indicated in one or more of a system information block (SIB) or in radio resource control (RRC) signaling;
- or
- a preconfigured order.
7 more elements
A method for wireless communications by a user equipment (UE), comprising:
- performing a relay reselection procedure with a remote UE separately from releasing a unicast link between the UE and the remote UE, wherein:
- performing the relay reselection procedure comprises exchanging relay reselection request and relay reselection response messages via the unicast link between the UE and the remote UE;
- and
- the relay reselection response message indicates whether the relay reselection request was accepted;
- and
- releasing the unicast link between the UE and the remote UE, wherein an order in which the releasing the unicast link between the UE and the remote UE and the relay reselection procedure is performed is at least one of:
- indicated in one or more of a system information block (SIB) or in radio resource control (RRC) signaling;
- or
- a preconfigured order.
6 more elements
An apparatus for wireless communications by a user equipment (UE), comprising:
- one or more memories including executable instructions;
- and
- one or more processors configured to execute the executable instructions to cause the UE to:
- take one or more actions to trigger a relay reselection procedure separately from releasing a unicast link between the UE and a first relay UE, wherein:
- to take the one or more actions to trigger relay reselection, the one or more processors are configured to cause the UE to exchange, via the unicast link between the UE and the first relay UE, relay reselection request and relay reselection response messages that trigger the relay reselection procedure;
- and
- the relay reselection response message indicates whether the relay reselection request was accepted;
- establish a unicast link between the UE and a second relay UE;
- release the unicast link between the UE and the first relay UE, wherein an order in which the release of the unicast link between the UE and the first relay UE and the relay reselection procedure is performed is at least one of:
- indicated in one or more of a system information block (SIB) or in radio resource control (RRC) signaling;
- or
- a preconfigured order.
9 more elements
An apparatus for wireless communications by a user equipment (UE), comprising:
- one or more memories including executable instructions;
- and
- one or more processors configured to execute the executable instructions to cause the UE to:
- perform a relay reselection procedure with a remote UE separately from releasing a unicast link between the UE and the remote UE, wherein:
- in order to perform the relay reselection procedure, the one or more processors are configured to cause the UE to exchange relay reselection request and relay reselection response messages via the unicast link between the UE and the remote UE;
- and
- the relay reselection response message indicates whether the relay reselection request was accepted;
- release the unicast link between the UE and the remote UE, wherein an order in which the release of the unicast link between the UE and the remote UE and the relay reselection procedure is performed is at least one of:
- indicated in one or more of a system information block (SIB) or in radio resource control (RRC) signaling;
- or
- a preconfigured order.
