Abstract
Certain aspects of the present disclosure provide techniques for supporting UL-based mobility without DL zone signals. A DL zone signal may refer to a zone synchronization signal or a zone measurement reference signal. As described herein, a UE may perform certain operations upon power-up or RLF recovery, perform operations in each DRx cycle, and/or perform inter-zone handovers without relying on DL zone signals. Thus, aspects create a more user-centric environment and reduce and/or avoid transmission DL zone signals.
Claims20
A method of wireless communication by a user equipment (UE), comprising:
- transmitting a first chirp signal;
- receiving a first keep alive (KA) signal, in response to the first chirp signal, in a first wake period of a discontinuous receive (DRx) cycle;
- transmitting a second chirp signal based, at least in part, on information determined from the first KA signal;
- receiving a page in response to the second chirp signal;
- and
- in response to the received page, synchronizing to a serving transmit/receive point (TRP) using a physical cell identity channel (PCICH).
A method of wireless communication by a user equipment (UE), comprising:
- receiving a configuration for keep alive (KA) signals including at least one dense KA signal, the at least one dense KA signal received less frequently than non-dense KA signals;
- transmitting a first chirp signal;
- receiving a first KA signal, in response to the first chirp signal, in a first wake period of a discontinuous receive (DRx) cycle;
- and
- transmitting a second chirp signal based, at least in part, on information determined from the first KA signal.
An apparatus for wireless communications by a user equipment (UE), comprising:
- a transceiver configured to:
- transmit a first chirp signal;
- receive a first keep alive (KA) signal, in response to the first chirp signal, in a first wake period of a discontinuous receive (DRx) cycle;
- transmit a second chirp signal based, at least in part, on information determined from the first KA signal;
- and
- receive a page in response to the second chirp signal;
- and
- at least one processor configured to, in response to the received page, synchronize to a serving transmit/receive point (TRP) using a physical cell identity channel (PCICH).
An apparatus for wireless communications by a user equipment (UE), comprising:
- a transceiver configured to:
- receive a configuration for keep alive (KA) signals including at least one dense KA, the at least one dense KA received less frequently than non-dense KA signals;
- transmit a first chirp signal;
- receive a first KA signal, in response to the first chirp signal, in a first wake period of a discontinuous receive (DRx) cycle;
- and
- transmit a second chirp signal based, at least in part, on information determined from the first KA signal;
- and
- at least one processor.
