Abstract
Aspects described herein relate to generating, using an initial seed and a pseudo-random shift value, a scrambling sequence, scrambling, using the scrambling sequence, one or more codewords as part of generating a baseband signal for a wireless communication channel, and transmitting the baseband signal to a network node.
Claims30
An apparatus for wireless communication, comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- generate, using an initial seed and a pseudo-random shift value, a scrambling sequence, wherein the pseudo-random shift value is a function of one or more of a cell identifier associated with a network node, a radio network temporary identifier (RNTI) of the apparatus, a frame index of a frame associated with a wireless communication channel, a subframe index of a subframe associated with the wireless communication channel, or a slot index of a slot associated with the wireless communication channel;
- scramble, using the scrambling sequence, one or more codewords as part of generating a baseband signal for the wireless communication channel;
- and
- transmit the baseband signal to the network node.

An apparatus for wireless communication, comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- receive, from a user equipment (UE), a baseband signal for a wireless communication channel;
- generate, using an initial seed and a pseudo-random shift value, a scrambling sequence, wherein the pseudo-random shift value is a function of one or more of a cell identifier associated with the apparatus, a radio network temporary identifier (RNTI) of the UE, a frame index of a frame associated with the wireless communication channel, a subframe index of a subframe associated with the wireless communication channel, or a slot index of a slot associated with the wireless communication channel;
- and
- descramble, using the scrambling sequence, one or more codewords from the baseband signal.
