Abstract

Methods, systems, and devices for wireless communications are described. Some examples of the described techniques provide for time-division multiplexing (TDM) modem envelope enhancements. A user equipment (UE) may receive, from a network entity, a message scheduling a transport block or multiple transport blocks in a downlink slot that immediately precedes one or more non-downlink slots (e.g., uplink (U), special(S), or flexible (F) slots) in a TDD slot configuration. The UE may receive the transport block or the multiple transport blocks in the downlink slot, and may process at least a portion of the transport block or the multiple transport blocks during one or more time intervals that occur after the downlink slot. The transport block may satisfy a per-slot transport block size threshold that is associated with a hybrid automatic repeat request (HARQ) processing timeline.

First claim

What is claimed is:

1 . A user equipment (UE) for wireless communications, comprising:
one or more memories storing processor-executable code; and one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, a message scheduling a transport block or multiple transport blocks in a downlink slot that immediately precedes one or more non-downlink slots in a time-division duplexing slot configuration;
receive the transport block or the multiple transport blocks in the downlink slot, wherein the transport block satisfies a per-slot transport block size threshold that is associated with a hybrid automatic repeat request (HARQ) processing timeline;
determine that processing of at least a portion of the transport block or at least a portion of the multiple transport blocks during one or more time intervals is allowed for the downlink slot based at least in part on the one or more non-downlink slots comprising flexible slots; and
process the at least a portion of the transport block or the at least a portion of the multiple transport blocks during one or more time intervals that occur after the downlink slot.

2 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, a control message configuring the UE with the time-division duplexing slot configuration, wherein processing the at least a portion of the transport block or the at least a portion of the multiple transport blocks during the one or more time intervals is based at least in part on a mapping between the downlink slot and the one or more time intervals, the mapping being associated with the time-division duplexing slot configuration.

3 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, information indicating the one or more time intervals for processing the at least a portion of the transport block or the at least a portion of the multiple transport blocks.

4 . The UE of claim 3 , wherein the information is received via a downlink control information (DCI) message, a radio resource control (RRC) message, a medium access control control element (MAC-CE), or a combination thereof.

5 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive a control message comprising an indication of one or more slots for which the processing of the at least a portion of the transport block or the at least a portion of the multiple transport blocks during the one or more time intervals is allowed based at least in part on the one or more non-downlink slots comprising the flexible slots, wherein determining that the processing of the at least the portion of the multiple transport blocks during the one or more time intervals is allowed for the downlink slot is in accordance with the indication.

6 . The UE of claim 5 , wherein the control message comprises a downlink control information (DCI) message or a radio resource control (RRC) message.

7 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
transmit a capability message indicating a capability of the UE to process the at least a portion of the transport block or the at least a portion of the multiple transport blocks during the one or more time intervals, wherein the processing is based at least in part on the capability of the UE.

8 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
determine that a quantity of the multiple transport blocks satisfies a threshold, wherein processing the at least a portion of the multiple transport blocks is based at least in part on a timeline that is extended in response to the quantity of the multiple transport blocks satisfying the threshold.

9 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
determine that a size of the transport block satisfies the threshold, wherein processing the at least the portion of the transport block is based at least in part on a timeline that is extended in response to the size of the transport block satisfying the threshold.

10 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
determine that a processed quantity of the multiple transport blocks satisfies a processing threshold; and drop at least one of the multiple transport blocks in response to the processed quantity of the multiple transport blocks satisfying the processing threshold.

11 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive downlink data between the downlink slot and the one or more time intervals; and send an asynchronous HARQ message in response to the downlink data.

12 . The UE of claim 1 , wherein, to receive the multiple transport blocks, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive the multiple transport blocks in the downlink slot as part of a multiple-input multiple-output (MIMO) transmission, wherein processing the at least a portion of the multiple transport blocks during the one or more time intervals is based at least in part on the MIMO transmission in the downlink slot having a greater quantity of layers than a second MIMO transmission in a second downlink slot before the downlink slot.

13 . The UE of claim 1 , wherein, to receive the transport block, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive the transport block in the downlink slot as part of a multiple-input multiple-output (MIMO) transmission, wherein processing the at least a portion of the transport block during the one or more time intervals is based at least in part on a size of the transport block for a quantity of layers of the MIMO transmission exceeding a capability of the UE associated with the HARQ processing timeline.

14 . The UE of claim 1 , wherein, to receive the multiple transport blocks, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive the multiple transport blocks in the downlink slot as part of a carrier aggregation (CA) transmission, a multiple transmission and reception point (mTRP) transmission, an ultra-reliable and low-latency communications (URLLC) transmission, or a combination thereof, wherein processing the at least a portion of the multiple transport blocks during the one or more time intervals is based at least in part on the CA transmission, the mTRP transmission, the URLLC transmission, or a combination thereof.

15 . The UE of claim 1 , wherein, to receive the multiple transport blocks in the downlink slot, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive the multiple transport blocks in the downlink slot as part of a code block group (CBG)-based hybrid automatic repeat request (HARQ) retransmission, wherein processing the at least a por
