Multiple priority channel multiplexing
Techniques are described to address scenarios involving physical uplink channel conflicts. For example, a method includes performing a combined transmission of a first information multiplexed with a second information on a first physical channel resource selected from the first physical channel resource and a second physical channel resource, where the first physical channel resource and the second physical channel resource have different transmission priorities, where the first physical channel resource is configured to have a last symbol that is earlier in time compared to a last symbol configured for the second physical channel resource, and where the combined transmission is performed in response to the first physical channel resource being configured to include the first information that conflicts within a time period with the second physical channel resource being configured to include the second information.
1. A wireless communication method, comprising:
performing a combined transmission of an uplink control information (UCI) multiplexed with a first information on a first physical channel resource,
wherein the first physical channel resource has a low transmission priority that is lower than a high transmission priority of a second physical channel resource, and
wherein the combined transmission is performed in response to the first physical channel resource being configured to include the first information that conflicts within a time period with the second physical channel resource being configured to include a second information that includes the UCI,
wherein within the time period the second physical channel resource overlaps with at least some of the first physical channel resource to form an overlapping region within the time period,
wherein the first physical channel includes a first number of available time-frequency resources within the overlapping region that is less than a second number of time-frequency resources needed for the UCI in the combined transmission,
wherein a last symbol of a resource element (RE) occupied by the UCI in the combined transmission is not later in time than a last symbol of the second information to be carried by the second physical channel resource,
wherein the first physical channel resource include a physical uplink shared channel (PUSCH) and the second physical channel resource includes a physical uplink control channel (PUCCH).
2. The method of claim 1 , wherein the time period comprises one time slot of a radio frame.
3. An apparatus for wireless communication, comprising one or more processors configured to implement a method that causes the apparatus to:
perform a combined transmission of an uplink control information (UCI) multiplexed with a first information on a first physical channel resource,
wherein the first physical channel resource has a low transmission priority that is lower than a high transmission priority of a second physical channel resource, and
wherein the combined transmission is performed in response to the first physical channel resource being configured to include the first information that conflicts within a time period with the second physical channel resource being configured to include a second information that includes the UCI,
wherein within the time period the second physical channel resource overlaps with at least some of the first physical channel resource to form an overlapping region within the time period,
wherein the first physical channel includes a first number of available time-frequency resources within the overlapping region that is less than a second number of time-frequency resources needed for the UCI in the combined transmission,
wherein a last symbol of a resource element (RE) occupied by the UCI in the combined transmission is not later in time than a last symbol of the second information to be carried by the second physical channel resource,
wherein the first physical channel resource include a physical uplink shared channel (PUSCH) and the second physical channel resource includes a physical uplink control channel (PUCCH).
4. The apparatus of claim 3 , wherein the time period comprises one time slot of a radio frame.
5. A non-transitory computer readable program storage medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method, comprising:
performing a combined transmission of an uplink control information (UCI) multiplexed with a first information on a first physical channel resource,
wherein the first physical channel resource has a low transmission priority that is lower than a high transmission priority of a second physical channel resource, and
wherein the combined transmission is performed in response to the first physical channel resource being configured to include the first information that conflicts within a time period with the second physical channel resource being configured to include a second information that includes the UCI,
wherein within the time period the second physical channel resource overlaps with at least some of the first physical channel resource to form an overlapping region within the time period,
wherein the first physical channel includes a first number of available time-frequency resources within the overlapping region that is less than a second number of time-frequency resources needed for the UCI in the combined transmission,
wherein a last symbol of a resource element (RE) occupied by the UCI in the combined transmission is not later in time than a last symbol of the second information to be carried by the second physical channel resource,
wherein the first physical channel resource include a physical uplink shared channel (PUSCH) and the second physical channel resource includes a physical uplink control channel (PUCCH).
6. The non-transitory computer readable program storage medium of claim 5 , wherein the time period comprises one time slot of a radio frame.
