PUCCH Resource Allocation and Use

摘要

A base station determines a first set of PUCCH resources to use for a first set of UEs to send acknowledgment information to the base station for a first group of DL subframes. The first set of PUCCH resources starts at a first index. The base station determines a second set of PUCCH resources to use for a second set of UEs to send acknowledgment information to the base station for a second group of DL subframes. The second set of PUCCH resources starts at a second index. The UEs in the first set only use the first set of PUCCH resources. The UEs in the second set use the first and second sets of PUCCH resources. For an UL reception, acknowledgement information is received from the first UEs using the first set of PUCCH resources and from the second UEs using the first and second sets of PUCCH resources.

1. A method, comprising:
determining by a base station a first set of physical uplink control channel resources to use for a first set of user equipment to send acknowledgment information to the base station for a first group of downlink subframes, wherein the first set of physical uplink control channel resources starts at a first index; determining by the base station a second set of physical uplink control channel resources to use for a second set of user equipment to send acknowledgment information to the base station for a second group of downlink subframes, wherein the user equipment in the first and second sets of user equipment are different, the second set of physical uplink control channel resources starts at a second index, the user equipment in the first set of user equipment only use the first set of physical uplink control channel resources to send the acknowledgment information to the base station for the first group of downlink subframes, and the user equipment in the second set of user equipment use the first set of physical uplink control channel resources to send the acknowledgment information to the base station for the first group of downlink subframes and use the second set of physical uplink control channel resources to send acknowledgment information to the base station for the second group of downlink subframes; and for an uplink reception by the base station, receiving acknowledgement information from the first user equipment using the first set of physical uplink control channel resources and receiving acknowledgement information from the second user equipment using the first and second sets of physical uplink control channel resources.
