Abstract
In general, to provide acknowledgment information by a first wireless device, the first wireless device sends repeated instances of acknowledgment information in respective first and second frame structures, in response to receipt of first information from a second wireless device. In addition, the first wireless device also sends further acknowledgment information in the second frame structure that is responsive to second information received from the second wireless device.
Claims21
An apparatus comprising:
- a memory;
- and
- at least one processing unit in communication with the memory, wherein the at least one processing unit and memory are configured to:
- determine an occurrence of a semi-persistently scheduled transmission on an uplink traffic channel in a first uplink subframe, wherein acknowledgement information is multiplexed on the uplink traffic channel in absence of a transmission of a repetition of acknowledgement information;
- receive a configuration for acknowledgment information transmission repetition, wherein the configuration includes a value for a number of transmission repetitions for acknowledgement information, and wherein acknowledgement information corresponding to downlink transmissions is to be repeated on consecutive uplink subframes according to the configuration;
- receive first and second scheduled transmissions from a second wireless device on respective first and second downlink (DL) subframes;
- prepare acknowledgement information for the first and second scheduled transmissions based on the configuration for acknowledgment information transmission repetition;
- transmit, using an uplink (UL) control channel different from an UL uplink traffic channel, the acknowledgement information for the first scheduled transmission together with the acknowledgement information for the second scheduled transmission in a first uplink subframe in a single message, wherein the first uplink subframe is subsequent to receiving the first and second scheduled transmissions;
- and
- skip transmission of the semi-persistently scheduled transmission on the uplink traffic channel in the first uplink subframe based determining the semi-persistently scheduled transmission would collide with ongoing repetitions of acknowledgement information for both of the first and second scheduled transmissions.
A wireless device comprising:
- an interface;
- and
- a processor coupled to the interface, wherein the interface and the processor are configured to:
- determine an occurrence of a semi-persistently scheduled transmission on an uplink traffic channel in a first uplink frame structure, wherein acknowledgement information is multiplexed on the uplink traffic channel in absence of a transmission of a repetition of acknowledgement information;
- receive a configuration for acknowledgment information transmission repetition, wherein the configuration includes a value for a number of transmission repetitions for acknowledgement information, and wherein acknowledgement information corresponding to downlink transmissions is to be repeated on consecutive uplink frame structures according to the configuration;
- receive first and second scheduled transmissions from a second wireless device on respective first and second downlink (DL) frame structures,
- prepare acknowledgement information for the first and second scheduled transmissions based on the configuration for acknowledgment information transmission repetition;
- transmit, using an uplink (UL) control channel different from an UL uplink traffic channel, the acknowledgement information for the first scheduled transmission together with the acknowledgement information for the second scheduled transmission in a first uplink frame structure in a single message, wherein the first uplink frame structure is subsequent to receiving the first and second scheduled transmissions;
- and
- skip transmission of the semi-persistently scheduled transmission on the uplink traffic channel in the first uplink frame structure based determining the semi-persistently scheduled transmission would collide with a transmission of repetition of acknowledgement information for both of the first and second scheduled transmissions.
A non-transitory memory medium storing program instructions executable by a processor of a wireless device to:
- determine an occurrence of a semi-persistently scheduled transmission on an uplink traffic channel in a first uplink frame structure, wherein acknowledgement information is multiplexed on the uplink traffic channel in absence of a transmission of a repetition of acknowledgement information;
- receive a configuration for acknowledgment information transmission repetition, wherein the configuration includes a value for a number of transmission repetitions for acknowledgement information, and wherein acknowledgement information corresponding to downlink transmissions is to be repeated on consecutive uplink frame structures according to the configuration;
- receive first and second scheduled transmissions from a second wireless device on respective first and second downlink (DL) frame structures;
- prepare acknowledgement information for the first and second scheduled transmissions based on the configuration for acknowledgment information transmission repetition;
- transmit, using an uplink (UL) control channel different from an UL uplink traffic channel, the acknowledgement information for the first scheduled transmission together with the acknowledgement information for the second scheduled transmission in a first uplink frame structure in a single message, wherein the first uplink frame structure is subsequent to receiving the first and second scheduled transmissions;
- and
- skip transmission of the semi-persistently scheduled transmission on the uplink traffic channel in the first uplink frame structure based determining the semi-persistently scheduled transmission would collide with a transmission of a repetition of acknowledgement information for both of the first and second scheduled transmissions.
