This application claims priority to U.S. Provisional Application No. 62/868,632, filed on Jun. 28, 2019, entitled “JOINT ACTIVATION AND/OR RELEASE FOR MULTIPLE CONFIGURED GRANT AND/OR SEMI-PERSISTENT SCHEDULING CONFIGURATIONS,” which is hereby expressly incorporated by reference herein.
Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for joint activation and/or release for multiple configured grant and/or semi-persistent scheduling configurations.
Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

What is claimed is:1. A method of wireless communication performed by a user equipment (UE), comprising:receiving a single downlink control information (DCI) message; mapping a bit sequence in the single DCI message to a configuration set that includes multiple downlink semi-persistent scheduling (SPS) configurations to be jointly released; and transmitting, through a physical uplink control channel (PUCCH) resource, a codebook that includes an acknowledgement bit based at least in part on the bit sequence indicating that one or more of the multiple downlink SPS configurations are to be jointly released, wherein the acknowledgement bit is an individual acknowledgement bit used to acknowledge another one of the multiple downlink SPS configurations that was released. 2. The method of claim 1 , wherein mapping the bit sequence in the single DCI message to the configuration set includes:identifying, based at least in part on the bit sequence, a codepoint that indicates an index associated with an individual configuration to be released; and jointly releasing each configuration in the configuration set based at least in part on determining that the individual configuration to be released is a member of the configuration set. 3. The method of claim 2 , wherein the index is a hybrid automatic repeat request (HARD) index associated with the individual configuration to be released. 4. The method of claim 2 , wherein each configuration in the configuration set is associated with a particular service type. 5. The method of claim 1 , wherein mapping the bit sequence in the single DCI message to the configuration set includes:identifying, based at least in part on the bit sequence, an individual bit that corresponds to the configuration set; and jointly releasing each configuration in the configuration set based at least in part on the individual bit that corresponds to the configuration set indicating that the configuration set is to be released. 6. The method of claim 5 , wherein the configuration set is a first configuration set, wherein the individual bit is a first individual bit, and wherein the method further comprises:identifying, based at least in part on the bit sequence in the single DCI message, a second individual bit that corresponds to a second configuration set; and jointly releasing each configuration in the second configuration set based at least in part on the second individual bit indicating that the second configuration set is to be released. 7. The method of claim 5 , wherein each configuration in the configuration set is associated with one or more of a particular service type or a particular parameter. 8. The method of claim 5 , wherein a length of the bit sequence corresponds to a quantity of different configuration sets associated with the UE. 9. The method of claim 5 , wherein at least one configuration in the configuration set is a member of one or more additional configuration sets, and wherein the at least one configuration is released based at least in part on the bit sequence in the single DCI message indicating that the configuration set and the one or more additional configuration sets are all to be released. 10. The method of claim 1 , wherein the UE is associated with multiple Configured Scheduling Radio Network Temporary Identifiers (CS-RNTIs) that respectively correspond to multiple configuration sets with one or more downlink semi-persistent scheduling (SPS) configurations or uplink CG configurations that can be jointly released. 11. The method of claim 1 , wherein the bit sequence is provided in a hybrid automatic repeat request (HARD) process number field of the DCI message. 12. The method of claim 1 , wherein the multiple downlink SPS configurations are grouped within the configuration set based at least in part on an indicator in a radio resource control (RRC) configuration message. 13. The method of claim 1 , wherein a length of the bit sequence is less than or equal to a length of a field in the DCI message used to separately activate or release an individual downlink SPS configuration or an individual uplink CG configuration. 14. The method of claim 1 , wherein the PUCCH resource used to transmit the codebook is determined based at least in part on the single DCI message. 15. The method of claim 1 , wherein the PUCCH resource used to transmit the codebook is indicated by a PUCCH resource indicator in a most recent DCI message, and wherein a location of the acknowledgement bit in the codebook is determined based at least in part on the single DCI message. 16.
