Abstract
Aspects of the disclosure relate to wireless communication systems configured to provide piggyback downlink control information within the physical downlink shared channel (PDSCH). A first downlink control information portion may be transmitted within the physical downlink control channel (PDCCH) and may include information indicating a size of a second downlink control information portion transmitted within the PDSCH.
Claims25
A method of wireless communication, comprising, at a scheduling entity:
- generating a first control information portion comprising first control information indicating at least a size of a second control information portion;
- transmitting the first control information portion within a control region of a slot;
- generating the second control information portion comprising second control information associated with a grant for the transmission of data traffic between the scheduling entity and one or more scheduled entities in wireless communication with the scheduling entity in one or more subsequent slots;
- and
- transmitting the second control information portion over all resource elements within a traffic region of the slot;
- wherein the second control information comprises a channel quality indicator request, a sounding reference signal request, or both.
3 more elements
A method of wireless communication, comprising, at a scheduling entity:
- generating a first control information portion comprising first control information indicating at least a size of a second control information portion;
- transmitting the first control information portion within a control region of a slot;
- generating the second control information portion comprising second control information comprising a concatenation of two or more control information components, each of the control information components comprising respective complete control information for a respective grant for the transmission of data traffic between the scheduling entity and one or more scheduled entities;
- and
- transmitting the second control information portion over all resource elements within a traffic region of the slot;
- wherein the second control information comprises a channel quality indicator request, a sounding reference signal request, or both.
3 more elements
A scheduling entity within a wireless communication network, comprising:
- a processor;
- a memory communicatively coupled to the processor;
- and
- a transceiver communicatively coupled to the processor, wherein the processor is configured to:
- generate a first control information portion comprising first control information indicating at least a size of a second control information portion;
- transmit the first control information portion within a control region of a slot;
- generate the second control information portion comprising second control information associated with a grant for the transmission of data traffic between the scheduling entity and one or more scheduled entities in wireless communication with the scheduling entity in one or more subsequent slots;
- and
- transmit the second control information portion over all resource elements within a traffic region of the slot;
- wherein the second control information comprises a channel quality indicator request, a sounding reference signal request, or both.
