Multiplexing techniques for overlapping channels with different priorities
Techniques are described for multiplexing content that overlap in time domain on at least two channels. An example wireless communication method includes performing a first determination, by a communication node, that a high priority feedback message to be transmitted on a control channel overlaps in time domain with a low priority feedback message to be transmitted on the control channel; performing a second determination, by the communication node, whether a multiplexing operation between the high priority feedback message and the low priority feedback message is allowed; and transmitting, in response to the first determination and in response to determining that the multiplexing operation is allowed, a multiplexed information in a resource in the control channel.
1. A wireless communication method, comprising:
performing a first determination, by a communication node, that a control channel with a high priority feedback message to be transmitted overlaps in time domain with another control channel with a low priority feedback message to be transmitted;
performing a second determination, by the communication node, that a multiplexing operation between the high priority feedback message and the low priority feedback message is allowed based on a Radio Resource Control (RRC) parameter, wherein each of the high priority feedback message and the low priority feedback message is less than or equal to two bits; and
transmitting, in response to the first determination and the second determination, a sequence representing multiplexed information,
wherein the multiplexed information represents the high priority feedback message multiplexed with the low priority feedback message,
wherein the sequence is transmitted in the control channel, and
wherein the sequence is selected based on a first set of one or more bits of the high priority feedback message and based on a second set of one or more bits of the low priority feedback message.
