Abstract
Fast Associated Control Channel (FACCH) information is combined if a first block of FACCH information and a repeated block of FACCH information each fail a respective integrity check. An algorithm for realizing repeated FACCH diversity combining gains for different codec and discontinuous transmission (DTX) configurations is applicable to Full Rate codecs, Half Rate codecs, and discontinuous transmission scenarios. A pair of buffers may be used in a ping-pong fashion to store decoding soft or hard decisions for failed FACCH blocks.
Claims30
A method of communication, comprising:
- receiving a first block;
- determining whether the first block is associated with a fast associated control channel (FACCH);
- conducting an integrity check on first FACCH information from the first block if the first block is associated with a FACCH;
- determining whether a buffer contains second FACCH information, wherein the determination is made if the integrity check fails;
- and
- combining the first FACCH information from the first block with the second FACCH information from the buffer if the buffer contains the second FACCH information.
An apparatus for communication, comprising:
- a memory device;
- a processing circuit coupled to the memory device and configured to:
- receive a first block;
- determine whether the first block is associated with a fast associated control channel (FACCH);
- conduct an integrity check on first FACCH information from the first block if the first block is associated with a FACCH;
- determine whether a buffer contains second FACCH information, wherein the determination is made if the integrity check fails;
- and
- combine the first FACCH information from the first block with the second FACCH information from the buffer if the buffer contains the second FACCH information.
An apparatus for communication, comprising:
- means for receiving a first block;
- means for determining whether the first block is associated with a fast associated control channel (FACCH);
- means for conducting an integrity check on first FACCH information from the first block if the first block is associated with a FACCH;
- means for determining whether a buffer contains second FACCH information, wherein the determination is made if the integrity check fails;
- and
- means for combining the first FACCH information from the first block with the second FACCH information from the buffer if the buffer contains the second FACCH information.
A non-transitory computer-readable medium storing computer-executable code, including code to:
- receive a first block;
- determine whether the first block is associated with a fast associated control channel (FACCH);
- conduct an integrity check on first FACCH information from the first block if the first block is associated with a FACCH;
- determine whether a buffer contains second FACCH information, wherein the determination is made if the integrity check fails;
- and
- combine the first FACCH information from the first block with the second FACCH information from the buffer if the buffer contains the second FACCH information.
