Method and apparatus for enhancing time domain-resource allocation framework in mobile communications
Various solutions for enhancing time domain-resource allocation (TD-RA) framework with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive an indication of a reference point. The apparatus may determine a start symbol position according to the reference point rather than a slot boundary. The apparatus may determining a TD-RA according to the start symbol position. The apparatus may perform a transmission according to the TD-RA.
1. A method, comprising:
receiving, by a processor of an apparatus, an indication of a reference point;
determining, by the processor, a start symbol position according to the reference point rather than a slot boundary;
determining, by the processor, a time domain-resource allocation (TD-RA) according to the start symbol position; and
performing, by the processor, a transmission according to the TD-RA,
wherein the reference point comprises a half-slot boundary.
2. The method of claim 1 , wherein the reference point comprises a reference time-domain region, and wherein the reference time-domain region comprises a predetermined number of symbols.
3. The method of claim 1 , wherein the reference point comprises a time position of a control signal.
4. The method of claim 1 , wherein the determining of the TD-RA comprises determining the TD-RA without a TD-RA information field in downlink control information (DCI).
5. A method, comprising:
receiving, by a processor of an apparatus, a configuration of a time domain-resource allocation (TD-RA) from a network node;
determining, by the processor, whether a predetermined condition is satisfied;
determining, by the processor, the TD-RA across a slot boundary in an event that the predetermined condition is satisfied; and
performing, by the processor, a transmission according to the TD-RA across the slot boundary,
wherein the predetermined condition comprises one of:
a maximum duration of the TD-RA being not greater than a predetermined number of symbols,
a scheduled physical data channel being located in a predetermined number of slots,
a duration of the TD-RA being greater than a threshold value, or
a required capability.
6. An apparatus, comprising:
a transceiver capable of wirelessly communicating with a network node of a wireless network; and
a processor communicatively coupled to the transceiver, the processor capable of:
receiving, via the transceiver, an indication of a reference point;
determining a start symbol position according to the reference point rather than a slot boundary;
determining a time domain-resource allocation (TD-RA) according to the start symbol position; and
performing, via the transceiver, a transmission according to the TD-RA,
wherein the reference point comprises a half-slot boundary.
7. The apparatus of claim 6 , wherein the reference point comprises a reference time-domain region, and wherein the reference time-domain region comprises a predetermined number of symbols.
8. The apparatus of claim 6 , wherein the reference point comprises a time position of a control signal.
9. The apparatus of claim 6 , wherein, in determining the TD-RA, the processor is capable of determining the TD-RA without a TD-RA information field in downlink control information (DCI).
10. An apparatus, comprising:
a transceiver capable of wirelessly communicating with a network node of a wireless network; and
a processor communicatively coupled to the transceiver, the processor capable of:
receiving, via the transceiver, a configuration of a time domain-resource allocation (TD-RA) from a network node;
determining whether a predetermined condition is satisfied;
determining the TD-RA across a slot boundary in an event that the predetermined condition is satisfied; and
performing, via the transceiver, a transmission according to the TD-RA across the slot boundary,
wherein the predetermined condition comprises one of:
a maximum duration of the TD-RA being not greater than a predetermined number of symbols,
a scheduled physical data channel being located in a predetermined number of slots,
a duration of the TD-RA being greater than a threshold value, or
a required capability.
