Abstract
A wireless communications device is provided with a first cache unit coupled to a memory unit, a wireless communications module, and a hybrid automatic repeat request (HARQ) combine component coupled to the first cache unit. The wireless communications module receives from a cellular network a wireless signal carrying first data corresponding to an HARQ process. The HARQ combine component reads second data corresponding to the HARQ process from the memory unit into the first cache unit, and combines the first data and the second data for an HARQ combining procedure.
Claims28
A wireless communications device, comprising:
- a first cache unit coupled to a memory unit;
- a wireless communications module receiving from a cellular network a wireless signal carrying first data corresponding to a hybrid automatic repeat request (HARQ) process;
- an HARQ combine component, coupled to the first cache unit, reading second data corresponding to the HARQ process from the memory unit into the first cache unit, and combining the first data and the second data for an HARQ combining procedure.
A wireless communications device, comprising:
- a cache unit coupled to a memory unit;
- a wireless communications module receiving from a cellular network a wireless signal carrying data corresponding to a hybrid automatic repeat request (HARQ) process;
- a HARQ combine component, coupled to the first cache unit, writing the data to the memory unit via the cache unit.
A method for HARQ buffering optimization in a wireless communications device, comprising:
- receiving from a cellular network a wireless signal carrying first data corresponding to a hybrid automatic repeat request (HARQ) process;
- reading second data corresponding to the HARQ process from an off-chip or off-die memory unit into a first cache unit;
- and
- combining the first data and the second data for an HARQ combining procedure.
