User equipments, base stations and methods
View Patent ↗A UE is described. The UE may include a higher layer processor configured to acquire a common dedicated radio resource control (RRC) configuration message and one or more dedicated RRC configuration messages. The common RRC message may include first information for indicating a slot format. The one or more dedicated RRC configuration messages including second information for configuring a semi-static downlink transmission and third information for configuring a semi-static uplink transmission. The UE may also include receiving circuitry configured to receive the semi-static downlink transmission. The UE may further include transmitting circuitry configured to transmit the semi-static uplink transmission. If the semi-static downlink reception and the semi-static uplink transmission are configured for a same set of symbol(s), the slot format indicates the set of symbol(s) as either downlink or uplink but not as flexible.
1. A user equipment (UE) comprising:
a higher layer processor configured to acquire, through radio resource control (RRC) configuration messages, first information for indicating a slot format, second information for configuring downlink reception(s), and third information for configuring uplink transmission(s);
receiving circuitry configured to perform the downlink reception(s); and
transmitting circuitry configured to perform the uplink transmission(s);
wherein
for a set of symbols of a slot that are indicated as flexible by the first information, the UE does not expect to receive both the second information configuring the downlink reception(s) by the UE in the set of symbols of the slot and the third information configuring the uplink transmission(s) from the UE in the set of symbols of the slot,
the first information is included in a common RRC configuration message, the second information and the third information are included in one or more dedicated RRC configuration messages.
2. The UE according to claim 1 , wherein
if the downlink reception(s) and the uplink transmission(s) are configured for a same set of symbol(s) in a slot, the slot format of the first information indicates the same set of symbol(s) as either downlink or uplink but not as flexible.
3. A base station configured to communicate with a user equipment (UE), the base station comprising:
a higher layer processor configured to send, through radio resource control (RRC) configuration messages, first information for indicating a slot format, second information for configuring downlink reception(s) by the UE, and third information for configuring uplink transmission(s) from the UE;
transmitting circuitry configured to perform downlink transmission(s) which corresponds to the downlink reception(s) by the UE; and
receiving circuitry configured to perform uplink reception(s) which corresponds to the uplink transmission(s) from the UE;
wherein
for a set of symbols of a slot that are indicated as flexible by the first information, the base station does not send both the second information configuring the downlink reception(s) by the UE in the set of symbols of the slot and the third information configuring the uplink transmission(s) from the UE in the set of symbols of the slot,
the first information is included in a common RRC configuration message, the second information and the third information are included in one or more dedicated RRC configuration messages.
4. The base station according to claim 3 , wherein
if the downlink reception(s) and the uplink transmission(s) are configured for a same set of symbol(s) in a slot, the slot format of the first information indicates the same set of symbol(s) as either downlink or uplink but not as flexible.
5. A method for a user equipment (UE), the method comprising:
acquiring, through radio resource control (RRC) configuration messages, first information for indicating a slot format, second information for configuring downlink reception(s), and third information for configuring uplink transmission(s);
performing the downlink reception(s); and
performing the uplink transmission(s);
wherein
for a set of symbols of a slot that are indicated as flexible by the first information, the UE does not expect to receive both the second information configuring the downlink reception(s) by the UE in the set of symbols of the slot and the third information configuring the uplink transmission(s) from the UE in the set of symbols of the slot,
the first information is included in a common RRC configuration message, the second information and the third information are included in one or more dedicated RRC configuration messages.
6. The method according to claim 5 , wherein
if the downlink reception(s) and the uplink transmission(s) are configured for a same set of symbol(s) in a slot, the slot format of the first information indicates the same set of symbol(s) as either downlink or uplink but not as flexible.
7. A method for a base station configured to communicate with a user equipment (UE), the method comprising:
sending, through radio resource control (RRC) configuration messages, first information for indicating a slot format, second information for configuring downlink reception(s) by the UE, and third information for configuring uplink transmission(s) from the UE;
performing downlink transmission(s) which corresponds to the downlink reception(s) by the UE; and
performing uplink reception(s) which corresponds to the uplink transmission(s) from the UE;
wherein
for a set of symbols of a slot that are indicated as flexible by the first information, the base station does not send both the second information configuring the downlink reception(s) by the UE in the set of symbols of the slot and the third information configuring the uplink transmission(s) from the UE in the set of symbols of the slot,
the first information is included in a common RRC configuration message, the second information and the third information are included in one or more dedicated RRC configuration messages.
8. The method according to claim 7 , wherein
if the downlink reception(s) and the uplink transmission(s) are configured for a same set of symbol(s) in a slot, the slot format of the first information indicates the same set of symbol(s) as either downlink or uplink but not as flexible.
