DETAILED DESCRIPTION

FIG.1is a diagram illustrating an example of a wireless network100, in accordance with the present disclosure. The wireless network100may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network100may include one or more base stations110(shown as a BS110a,a BS110b,a BS110c,and a BS110d), a user equipment (UE)120or multiple UEs120(shown as a UE120a,a UE120b,a UE120c,a UE120d,and a UE120e), and/or other network entities. A base station110is an entity that communicates with UEs120. A base station110(sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station110may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station110and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

In some aspects, the UE120may include a communication manager140. As described in more detail elsewhere herein, the communication manager140may perform one or more operations associated with dynamic component carriers configuration for uplink configured grants. Additionally, or alternatively, the communication manager140may perform one or more other operations described herein.

FIG.2is a diagram illustrating an example200of a base station110in communication with a UE120in a wireless network100, in accordance with the present disclosure. The base station110may be equipped with a set of antennas234athrough234t,such as T antennas (T≥1). The UE120may be equipped with a set of antennas252athrough252r,such as R antennas (R≥1).

In some aspects, the UE includes means for receiving an indication of a priority rule for prioritizing overlapping configured grant opportunities associated with a periodic data transmission, wherein the overlapping configured grant opportunities are associated with component carriers having a same logical channel priority, wherein the priority rule indicates a priority of a first component carrier associated with a first configured grant opportunity, of the overlapping configured grant opportunities, relative to a priority of a second component carrier associated with a second configured grant opportunity, of the overlapping configured grant opportunities, based at least in part on whether the UE is associated with a survival state; and/or means for transmitting the periodic data transmission according to the overlapping configured grant opportunities based at least in part on the priority rule. The means for the UE to perform operations described herein may include, for example, one or more of communication manager140, antenna252, modem254, MIMO detector256, receive processor258, transmit processor264, TX MIMO processor266, controller/processor280, or memory282.

In some aspects, the UE includes means for receiving a configured grant associated with a periodic data transmission, wherein the configured grant allocates a first set of resources associated with a non-survival state and a second set of resources associated with a survival state; means for transmitting a first data transmission of the periodic data transmission via the first set of resources based at least in part on the UE being associated with the non-survival state; and/or means for transmitting a second data transmission of the periodic data transmission via the second set of resources based at least in part on the UE being associated with the survival state. The means for the UE to perform operations described herein may include, for example, one or more of communication manager140, antenna252, modem254, MIMO detector256, receive processor258, transmit processor264, TX MIMO processor266, controller/processor280, or memory282.

FIG.3is a diagram illustrating an example300of uplink configured grant (CG) communication, in accordance with the present disclosure. CG communications may include periodic uplink communications that are configured for a UE, such that the base station does not need to send separate downlink control information (DCI) to schedule each uplink communication, thereby conserving signaling overhead.

As shown in example300, a UE may be configured with a CG configuration for CG communications. For example, the UE may receive the CG configuration via a radio resource control (RRC) message transmitted by a base station. The CG configuration may indicate a resource allocation associated with CG uplink communications (e.g., in a time domain, a frequency domain, a spatial domain, and/or a code domain) and a periodicity at which the resource allocation is repeated, resulting in periodically reoccurring scheduled CG occasions305for the UE. In some examples, the CG configuration may identify a resource pool or multiple resource pools that are available to the UE for an uplink transmission. The CG configuration may configure contention-free CG communications (e.g., where resources are dedicated for the UE to transmit uplink communications) or contention-based CG communications (e.g., where the UE contends for access to a channel in the configured resource allocation, such as by using a channel access procedure or a channel sensing procedure).

The base station may transmit CG activation DCI to the UE to activate the CG configuration for the UE. The base station may indicate, in the CG activation DCI, communication parameters, such as an MCS, a resource block (RB) allocation, and/or antenna ports, for the CG physical uplink shared channel (PUSCH) communications to be transmitted in the scheduled CG occasions305. The UE may begin transmitting in the CG occasions305based at least in part on receiving the CG activation DCI. For example, beginning with a next scheduled CG occasion305subsequent to receiving the CG activation DCI, the UE may transmit a PUSCH communication in the scheduled CG occasions305using the communication parameters indicated in the CG activation DCI. The UE may refrain from transmitting in configured CG occasions305prior to receiving the CG activation DCI.

The base station may transmit CG reactivation DCI to the UE to change the communication parameters for the CG PUSCH communications. Based at least in part on receiving the CG reactivation DCI, the UE may begin transmitting in the scheduled CG occasions305using the communication parameters indicated in the CG reactivation DCI. For example, beginning with a next scheduled CG occasion305subsequent to receiving the CG reactivation DCI, the UE may transmit PUSCH communications in the scheduled CG occasions305based at least in part on the communication parameters indicated in the CG reactivation DCI.

In some cases, such as when the base station needs to override a scheduled CG communication for a higher priority communication, the base station may transmit CG cancellation DCI to the UE to temporarily cancel or deactivate one or more subsequent CG occasions305for the UE. The CG cancellation DCI may deactivate only a subsequent one CG occasion305or a subsequent N CG occasions305(where N is an integer). CG occasions305after the one or more (e.g., N) CG occasions305subsequent to the CG cancellation DCI may remain activated. Based at least in part on receiving the CG cancellation DCI, the UE may refrain from transmitting in the one or more (e.g., N) CG occasions305subsequent to receiving the CG cancellation DCI. As shown in example300, the CG cancellation DCI cancels one subsequent CG occasion305for the UE. After the CG occasion305(or N CG occasions) subsequent to receiving the CG cancellation DCI, the UE may automatically resume transmission in the scheduled CG occasions305.

The base station may transmit CG release DCI to the UE to deactivate the CG configuration for the UE. The UE may stop transmitting in the scheduled CG occasions305based at least in part on receiving the CG release DCI. For example, the UE may refrain from transmitting in any scheduled CG occasions305until another CG activation DCI is received from the base station. Whereas the CG cancellation DCI may deactivate only a subsequent one CG occasion305or a subsequent N CG occasions305, the CG release DCI deactivates all subsequent CG occasions305for a given CG configuration for the UE until the given CG configuration is activated again by a new CG activation DCI.

In some cases, the base station may determine a communication service availability parameter and/or a survival time associated with a periodic data transmission to be transmitted by the UE. For example, the base station may determine the communication service parameter and/or the survival time based at least in part on a quality of service (QoS) associated with the periodic data transmission. A communication service availability parameter may indicate whether a communication system (e.g., a communication link) for communications between the base station and the UE functions as contracted. The UE may be associated with a non-survival state based at least in part on availability criteria for transmitted packets being satisfied. The UE may be associated with a survival state based at least in part on the availability criteria not being satisfied.

For example, the UE may be associated with the survival state based at least in part on a receiving device (e.g., the base station) failing to successfully receive one or more of the periodic data transmissions. In some cases, the UE may be associated with the non-survival state until a quantity of consecutive data transmissions fail to be successfully received by the receiving device. For example, the UE may be configured with a survival time and/or a survival state that is associated with a radio bearer (e.g., a data radio bearer). In other words, the survival time and/or survival state may be configured for a given radio bearer. In some examples, the UE may activate or transition to a survival state based on detecting that a data transmission was not successfully received by the receiving device. For example, the UE may receive an indication of a negative acknowledgement (NACK) associated with the data transmission. In other examples, the UE may determine that the data transmission was not successfully received based on receiving an indication (e.g., DCI) to retransmit the data transmission. For example, the UE may activate or transition to a survival state based on receiving DCI indicating a retransmission for a CG associated with a radio bearer that is configured with a survival time or a survival state.

The UE may remain in the survival state until a data transmission is successfully received by the receiving device. “Survival time” may refer to a maximum period of time that the UE may remain in the survival state. Upon expiration of the survival time, the UE may transition to a down or inactive state in which the UE no longer operates and/or transmits data to the receiving device.

For example, the UE may continue to transmit data to the receiving device while the UE is in the survival state. If the receiving device does not successfully receive a data transmission prior to the expiration of the survival time, the UE may transition to the down or inactive state. To avoid the UE transitioning to the down or inactive state, upon failing to successfully receive a data transmission from the UE, the receiving device (e.g., the base station110) may transmit a new CG or a CG activation DCI to the UE to increase a reliability of the periodic data transmission. For example, the receiving device may transmit a new CG or a CG activation DCI to the UE to enable the UE to transmit the periodic data transmission via different resources (e.g., a different component carrier, different frequency resources, or different time resources).

However, in some cases, the survival time may be relatively short (e.g., 0.5 ms or 1.0 ms) and may expire prior to the UE receiving the new CG or CG activation DCI, the UE transmitting data via the different resources, and/or the receiving device successfully receiving the data transmission via the different resources.

Some techniques and apparatuses described herein enable different resources to be quickly activated upon a UE entering a survival state without requiring the UE to receive a new CG or CG activation DCI prior to utilizing the different resources.

FIG.4is a diagram illustrating an example400associated with dynamic configuration of component carrier for uplink configured grants, in accordance with the present disclosure. As shown inFIG.4, example400includes communication between a UE120and a receiving device (e.g., a base station110) (not shown). In some aspects, the UE120and the receiving device may be included in a wireless network, such as wireless network100. The UE120and the receiving device may communicate via a wireless access link, which may include an uplink and a downlink.

In some aspects, the UE120may receive multiple CGs providing overlapping CG opportunities associated with a periodic data transmission. In some aspects, the CG opportunities may overlap in time or frequency, among other examples. For example, as shown inFIG.4, the UE120may receive a CG allocating resources of a first component carrier (e.g., CC1, as shown) and a CG allocating resources of a second component carrier (e.g., CC2, as shown) that overlap in time with the resources of the second component carrier.

In some aspects, the UE120may attempt to prioritize the overlapping CG occasions. For example, the UE120may select a hybrid automatic repeat request (HARQ) identifier (e.g., a media access control (MAC) packet data unit (PDU)) to be carried by the first component carrier and a HARQ identifier to be carried by the second component carrier based at least in part on a logical channel restriction associated with the first component carrier and/or the second component carrier, HARQ sharing rules, and/or logical channel priorities associated with the first component carrier and the second component carrier. The UE120may prioritize the CG opportunity associated with the higher logical channel priority relative to the other CG opportunities.

In some aspects, the CG opportunities have the same logical channel priorities. For example, the data to be transmitted may be included in a periodic data transmission and the UE120may select the same HARQ identifier or MAC PDU for each of the overlapping CG opportunities.

The UE120may determine a priority of the overlapping CG opportunities based at least in part on a priority rule. The UE120may receive the priority rule via DCI or a MAC control element (MAC-CE).

The priority rule may indicate a priority of a CG opportunity relative to the other CG opportunities. For example, the overlapping CG opportunities may include a first CG opportunity and a second CG opportunity. The priority rule may indicate that the first CG opportunity is always prioritized over the second CG opportunity (or that the second CG opportunity is always prioritized over the first CG opportunity).

In some aspects, the priority rule may be a dynamic priority rule. In some aspects, the dynamic priority rule may include a set of priority rules and the UE120may determine a priority rule to be utilized based at least in part on one or more conditions being satisfied. For example, the dynamic priority rule may indicate a first priority rule associated with the UE being in a non-survival state and a second priority rule associated with the UE being in a survival state. The first priority rule may indicate that the first component carrier is prioritized over the second component carrier based at least in part on the UE being in the non-survival state. The second priority rule may indicate that the second component carrier is prioritized over the first component carrier based at least in part on the UE being in the survival state.

As shown inFIG.4, the UE120may prioritize the CG opportunity associated with the first component carrier based at least in part on the priority rule indicating that the UE120is to prioritize the first CG opportunity over the second CG opportunity when the UE is in the non-survival state. The UE120may transmit a PUSCH405via resources of the first component carrier (rather than transmit a PUSCH410via resources of the second component carrier) based at least in part on prioritizing the first CG opportunity over the second CG opportunity.

In some aspects, the PUSCH405may not be successfully received and/or decoded by the receiving device. As shown by reference number415, the UE120may receive a physical downlink control channel (PDCCH) indicating a NACK from the receiving device. In some aspects, the indication of the NACK may include a HARQ NACK. In some aspects, the indication may include DCI allocating resources for retransmitting the PUSCH405. In such examples, the UE may not receive a HARQ NACK (e.g., and may determine that the PUSCH405was not successfully received based on receiving the DCI allocating resources for retransmitting the PUSCH405).

As shown by reference number420, the UE120may enter a survival state based at least in part on receiving the indication of the NACK. As shown by reference number425, the UE120may retransmit the PUSCH (e.g., via resources of the first component carrier that are indicated by the DCI).

In some aspects, the priority rule may indicate that the first component carrier is always prioritized over the second component carrier (or that the second component carrier is always prioritized over the first component carrier). The UE120may transmit a next data transmission of the periodic data transmission (e.g., PUSCH430, as shown inFIG.4) via resources of the first component carrier based at least in part on the priority rule indicating that the first component carrier is always prioritized over the second component carrier.

In some aspects, the priority rule may be a dynamic priority rule. The dynamic priority rule may indicate that the first component carrier is prioritized over the second component carrier (or that the second component carrier is prioritized over the first component carrier) when the UE120is in the non-survival state and/or that the second component carrier is prioritized over the first component carrier (or that the first component carrier is prioritized over the second component carrier) when the UE120is in the survival state. The UE120may transmit a next data transmission of the periodic data transmission (e.g., PUSCH435, as shown inFIG.4) via resources of the second component carrier based at least in part on the priority rule indicating that the second component carrier is prioritized over the first component carrier when the UE120is in the survival state and based at least in part on the UE120being in the survival state.

In some aspects, the PUSCH435may be successfully received by the receiving device prior to the expiration of the survival time. The UE120may transition from the survival state to the non-survival state based at least in part on the PUSCH435being successfully received by the receiving device prior to the expiration of the survival time.

In some aspects, the UE120may receive an indication of another priority rule for prioritizing the overlapping CG opportunities. The UE120may receive the priority rule via DCI or a MAC-CE. The other priority rule may indicate a new, different, or modified priority of the CG opportunities relative to the other CG opportunities. The UE120may transmit a remaining portion of the periodic data transmission according to the other priority rule.

FIG.5is a diagram illustrating an example500associated with dynamic configuration of component carrier for uplink configured grants, in accordance with the present disclosure. As shown inFIG.5, example500includes communication between a UE120and a receiving device (e.g., a base station110) (not shown). In some aspects, the UE120and the receiving device may be included in a wireless network, such as wireless network100. The UE120and the receiving device may communicate via a wireless access link, which may include an uplink and a downlink.

In some aspects, the UE120may receive multiple CGs providing overlapping CG opportunities associated with a periodic data transmission. In some aspects, the CG opportunities may overlap in time or frequency, among other examples. For example, as shown inFIG.5, the UE120may receive a CG allocating resources of a first component carrier (e.g., CC1, as shown) and a CG allocating resources of a second component carrier (e.g., CC2, as shown) that overlap in time with the resources of the second component carrier.

In some aspects, the UE120may attempt to prioritize the overlapping CG occasions. For example, the UE120may select a HARQ identifier to be carried by the first component carrier and a HARQ identifier to be carried by the second component carrier based at least in part on a logical channel restriction associated with the first component carrier and/or the second component carrier, HARQ sharing rules, and/or logical channel priorities associated with the first component carrier and the second component carrier. The UE120may prioritize the CG opportunity associated with the higher logical channel priority relative to the other CG opportunities.

In some aspects, the CG opportunities have the same logical channel priorities. For example, the data to be transmitted may be included in a periodic data transmission and the UE120may select the same HARQ identifier or MAC PDU for each of the overlapping CG opportunities. The UE120may determine a priority of the overlapping CG opportunities based at least in part on a priority rule. The UE120may receive an indication of the priority rule via DCI or a MAC-CE.

The priority rule may indicate a priority of a CG opportunity relative to the other CG opportunities. For example, the overlapping CG opportunities may include a first CG opportunity and a second CG opportunity. The priority rule may indicate that the first CG opportunity is always prioritized over the second CG opportunity (or that the second CG opportunity is always prioritized over the first CG opportunity).

In some aspects, the priority rule may be a dynamic priority rule. In some aspects, the dynamic priority rule may include a set of priority rules and the UE120may determine a priority rule to be utilized based at least in part on one or more conditions being satisfied. For example, the dynamic priority rule may indicate a first priority rule associated with the UE being in a non-survival state and a second priority rule associated with the UE being in a survival state. The first priority rule may indicate that the first component carrier is prioritized over the second component carrier based at least in part on the UE being in the non-survival state. The second priority rule may indicate that the second component carrier is prioritized over the first component carrier based at least in part on the UE being in the survival state.

In some aspects, an RRC configuration and/or the priority rule may indicate that packet data convergence protocol (PDCP) duplication is activated based at least in part on the UE receiving an indication of a NACK associated with a data transmission of the periodic data transmission (or receiving a DCI scheduling a retransmission of the data transmission). In some aspects, the priority rule may indicate that the CG opportunity associated with the first component carrier is prioritized over the CG opportunity associated with the second component carrier when the UE120is in the non-survival state and when the UE120is in the survival state. In some aspects, the RRC configuration and/or the priority rule may indicate that the duplicated packet is to be transmitted via the CG opportunity associated with the second component carrier.

As shown inFIG.5, the UE120may prioritize the CG opportunity associated with the first component carrier based at least in part on the priority rule indicating that the UE120is to prioritize the first CG opportunity over the second CG opportunity when the UE is in the non-survival state. The UE120may transmit a PUSCH505via resources of the first component carrier (rather than transmit a PUSCH510via resources of the second component carrier) based at least in part on prioritizing the first CG opportunity over the second CG opportunity.

In some aspects, the PUSCH505may not be successfully received and/or decoded by the receiving device. As shown by reference number515, the UE120may receive a PDCCH indicating a NACK from the receiving device. In some aspects, the indication of the NACK may include a HARQ NACK. In some aspects, the indication may include DCI allocating resources for retransmitting the PUSCH505. In such examples, the UE may not receive a HARQ NACK (e.g., and may determine that the PUSCH505was not successfully received based on receiving the DCI allocating resources for retransmitting the PUSCH505).

As shown by reference number520, the UE120may enter a survival state based at least in part on receiving the indication of the NACK. As shown by reference number525, the UE120may retransmit the PUSCH505(e.g., via resources of the first component carrier that are indicated by the DCI). As shown by reference number530, the UE120may activate PDCP duplication based at least in part on receiving the NACK.

In some aspects, the priority rule may indicate that the first component carrier is always prioritized over the second component carrier (or that the second component carrier is always prioritized over the first component carrier). The UE120may transmit a next data transmission of the periodic data transmission (e.g., PUSCH535-1, as shown inFIG.5) via resources of the first component carrier based at least in part on the priority rule indicating that the first component carrier is always prioritized over the second component carrier.

In those aspects, an RRC configuration and/or the priority rule may indicate that PDCP duplication is activated based at least in part on the UE120receiving the indication of the NACK and that resources of the second component carrier are utilized for PDCP duplication. The UE120may transmit a duplicate of the PUSCH535-1(e.g., PUSCH535-2, as shown inFIG.5) based at least in part on PDCP duplication being activated. The UE120may transmit the duplicate of the PUSCH535-1via the second component carrier based at least in part on the RRC configuration and/or the priority rule indicating that the PDCP duplication is to utilize the resources of the second component carrier.

In some aspects, the priority rule may be a dynamic priority rule. The dynamic priority rule may indicate that the first component carrier is prioritized over the second component carrier (or that the second component carrier is prioritized over the first component carrier) when the UE120is in the non-survival state and/or that the second component carrier is prioritized over the first component carrier (or that the first component carrier is prioritized over the second component carrier) when the UE120is in the survival state. For example, in the survival state, the UE120may prioritize the second component carrier in the survival state (e.g., for transmissions of the PUSCH535-1) and may duplicate transmissions of the PUSCH535-1using the first component carrier (e.g., via PDCP duplication).

In some aspects, the PUSCH535-1and/or the PUSCH535-2may be successfully received by the receiving device prior to the expiration of the survival time. The UE120may transition from the survival state to the non-survival state based at least in part on the PUSCH535-1and/or the PUSCH535-2being successfully received by the receiving device prior to the expiration of the survival time.
