Abstract
The first circuitry may be operable to establish a first UE Receive (Rx) beam as being for reception of data from a first eNB. The second circuitry may be operable to process a transmission including Downlink Control Information (DCI), wherein the DCI carries an eNB cell-switching indicator. The first circuitry may also be operable to establish a second UE Rx beam as being for reception of data from a second eNB based on the eNB cell-switching indicator.
Claims21
1-24. (canceled)
An apparatus of a User Equipment (UE) operable to communicate with multiple transmission and reception points (TRPs) associated with a cell of a wireless network, the apparatus comprising:
- a memory configured to store instructions;
- a processor coupled to the memory, and when executing the instructions, configured to cause the UE to:
- receive a configuration comprising multiple control channel sets, a first control channel set of the multiple control channel sets associated with an identity of a first TRP of the multiple TRPs;
- determine a first receive beam to apply based on the identity of the first TRP;
- and
- monitor the first control channel set for first downlink control information with the first receive beam applied based on the configuration.
An apparatus of a User Equipment (UE) operable to communicate with multiple transmission and reception points (TRPs) associated with a cell of a wireless network, the apparatus comprising:
- a memory configured to store instructions;
- a processor coupled to the memory, and when executing the instructions, configured to cause the UE to:
- receive a configuration comprising multiple search spaces, each search space of the multiple search spaces is associated with an identity of a TRP of the multiple TRPs;
- determine downlink control channel candidates from more than one search space of the multiple search spaces that carry repetitions of a control channel transmission;
- determine receive beams for downlink control channel candidates;
- and
- decode downlink control channel candidates with the determined receive beams applied.
An apparatus of a network device operable to communicate with a User Equipment (UE) via multiple transmission and reception points (TRPs) associated with a cell of a wireless network, the apparatus comprising:
- a memory configured to store instructions;
- a processor coupled to the memory, and when executing the instructions, configured to cause the network device to:
- transmit, to the UE, reference signal from the multiple TRPs;
- receive a measurement report including measurement results of reference signal received from the multiple TRPs, the measurement report indicates or suggests a receive beam for each of the multiple TRPs;
- transmit a configuration comprising control channel sets and/or search spaces correspondingly associated with the multiple TRPs;
- and
- transmit, to the UE, downlink control information respectively from the multiple TRPs on the control channel sets.
