context: 7.1.5c.1.1 Definition and applicability All UEs which support 1.28Mcps TDD and SPS operation. 7.1.5c.1.2 Conformance requirement When the HS-DSCH SPS operation is enabled, the UE shall maintain cyclic virtual IR buffers with number of N where N is configured by higher layer as in [7]. And the value tagged to the virtual IR buffers should be all set to NULL. For each received MAC-hs PDU provided by the lower layers the UE shall: - If the associated HS-SCCH corresponds to an HS-SCCH SPS retransmission as defined in subclause 4.6C of [19]: - if the data in the virtual IR buffer tagged with the value [2*CFN + subframe number - 4 â PTR] mod 512 has not been decoded successfully: - combine the received data with the data currently in the virtual IR buffer tagged with the value [2*CFN + subframe number - 4 - PTR] mod 512, where PTR is the value of the pointer to the previous transmission as defined in subclause 4.6C of [19]. - If the data in the virtual IR buffer has been successfully decoded
description: Infrared (IR) is a technology standard used in wireless communication and data transmission. It defines specifications for maintaining cyclic virtual IR buffers for High-Speed Downlink Shared Channel (HS-DSCH) Single Packet Scheduling (SPS) operation.
explanation: The description explicitly states that Infrared is a 'technology standard' governing telecommunications operations, particularly within the context of 3GPP TS 34.123 which outlines specifications for wireless communication.
