Abstract: Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a semi-persistent scheduling (SPS) message indicating transmission of a first packet during a first period of a first hybrid automatic repeat request (HARQ) process, and a configuration for TTI-bundled transmission. The apparatus transmits a first TTI-bundled packet on the first resources during the first period of the first HARQ process. The apparatus identifies second resources for transmitting a second TTI-bundled packet during a second period of the first HARQ process based on the SPS message. The apparatus determines whether to offset transmission of the second TTI-bundled packet to a period of a second HARQ process when at least one of the second resources for transmitting the second TTI-bundled packet overlaps with at least one resource used for retransmitting the first TTI-bundled packet according to the first HARQ process.
