Systems and methods for accommodating specific user equipments

Abstract

A method by a user equipment (UE) is described. The method includes determining a repetition level, determining a initialization value for a scrambling sequence generator based on the repetition level, generating the scrambling sequence, and applying the scrambling sequence for a Physical Downlink Shared Channel (PDSCH). The repetition level is associated with the PDSCH and determined by a Radio Resource Control (RRC) configuration.

1 . A method by a user equipment (UE), comprising:
 determining a level associated with a Physical Downlink Shared Channel (PDSCH);   determining an initialization value for a scrambling sequence generator with use of a formula including a first parameter based on the level and a second parameter based on a Radio Network Temporary Identifier (RNTI);   generating a scrambling sequence by initializing the scrambling sequence generator with use of the initialization value; and   applying the scrambling sequence for the PDSCH, wherein   
       a block of bits of the PDSCH is scrambled by the scrambling sequence, and
 the level is associated with the PDSCH and determined by a Radio Resource Control (RRC) configuration and the level is a size of a bundle for the PDSCH. 
 
     
     
         2 . The method of  claim 1 , wherein each transmission that is a part of a same bundle is for a same Hybrid automatic repeat request (HARQ) process. 
     
     
         3 . A method by a base station, comprising:
 determining a level associated with a Physical Downlink Shared Channel (PDSCH);   determining an initialization value for a scrambling sequence generator with use of a formula including a first parameter based on the level and a second parameter based on a Radio Network Temporary Identifier (RNTI);   generating a scrambling sequence by initializing the scrambling sequence generator with use of the initialization value; and   applying the scrambling sequence for the PDSCH, wherein   
       a block of bits of the PDSCH is scrambled by the scrambling sequence, and

         5 . A user equipment (UE), comprising:
 a processor; and   memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:   determine a level associated with a Physical Downlink Shared Channel (PDSCH);   determine an initialization value for a scrambling sequence generator with use of a formula including a first parameter based on the level and a second parameter based on a Radio Network Temporary Identifier (RNTI);   generate a scrambling sequence by initializing the scrambling sequence generator with use of the initialization value; and   apply the scrambling sequence for the PDSCH, wherein   
       a block of bits of the PDSCH is scrambled by the scrambling sequence, and
 the level is associated with the PDSCH and determined by a Radio Resource Control (RRC) configuration and the level is a size of a bundle for the PDSCH.
