HARQ SOFT BIT BUFFER PARTITIONING FOR CARRIER AGGREGATION
First Claim
Patent Images
15. A user equipment device configured to handle hybrid automatic repeat request (HARQ) operations for aggregated carriers, comprising:
- a processor and a HARQ subsystem to determine a total number of soft buffer bits to be partitioned for HARQ operations, and to partition the total number of soft buffer bits among a plurality of aggregated carriers to obtain a plurality of soft buffer partitions having relative sizes, where the relative size of each soft buffer partition for each carrier in the plurality of aggregated carriers is computed as a function of a carrier-related property associated with the carrier.

Abstract
A method, system and device are provided for partitioning a HARQ soft bit buffer between aggregated carriers as a function of carrier-related weighting factors so that the total number of soft buffer bits are efficiently allocated to obtain a plurality of soft buffer partitions for the plurality of aggregated carriers which are sized based on relative carrier-related weighting factors.

28. A network element configured for handling hybrid automatic repeat request (HARQ) operations comprising a processor and a communications subsystem, where the network element is configured to:
-
configure a user equipment device to receive data packets on a plurality of aggregated carriers; transmit data packets to the user equipment device on the plurality of aggregated carriers; and transmit a plurality of carrier-dependent weighting factors to the user equipment device which correspond respectively to the plurality of aggregated carriers, where the carrier-dependent weighting factors are transmitted for use by the user equipment device in partitioning a total number of soft buffer bits based at least in part on the carrier-dependent weighting factors to obtain a plurality of soft buffer partitions for the plurality of aggregated carriers which are sized based on relative carrier-dependent weighting factors. - View Dependent Claims (29, 30, 31)
