ABBREVIATED BLIND DETECTION IN WIRELESS COMMUNICATION SYSTEMS INCLUDING LTE

摘要

A method and apparatus are provided for abbreviating the blind decoding process performed by a UE, such as an LTE UE, on control channel data such as PDCCH data of PRB pairs of a set of PRB pairs transmitted concurrently within a subframe. In some embodiments, only a prioritized portion of the PDCCH data is decoded, thereby expediting blind decoding. In some embodiments, a reduced number of encoding options for the PDCCH data is used, and blind decoding is expedited by considering only such options as possibilities. When blind decoding of the PDCCH data is completed before the end of the subframe, this may be used to identify and discard corresponding PDSCH data which is irrelevant to the UE. The prioritized portion may be adjusted as needed to include the CSS so as not to miss certain critical data.

主权项

1. A method of supporting downlink communication in an LTE wireless communication system, comprising:
wirelessly receiving a set of Physical Resource Block (PRB) pairs at a UE, each PRB pair of the set of PRB pairs comprising PDCCH data followed by PDSCH data, each PRB pair of the set of PRB pairs having been transmitted concurrently within a subframe; concurrently with receipt of said set of PRB pairs, performing blind decoding by the UE of a prioritized portion of the PDCCH data of PRB pairs of the set of PRB pairs, wherein said blind decoding is completed prior to expiry of the subframe; and for at least some PRB pairs for which the decoded PDCCH data thereof is indicative that the PDSCH data of the same subframe is devoid of data intended for the UE, refraining, by the UE, from one or both of buffering and decoding of at least some of said PDSCH data.
