Embodiment 1

[0079] In this embodiment, for CoMP scenario 3, high layer signaling configures parameters for determining a PUCCH sequence group number for user equipment.

Embodiment 1

[0080] Present embodiment 1 method comprises the steps:

[0081] Step 201: The base station configures parameters for determining the PUCCH sequence group number for the user terminal through high-level signaling, such as a virtual cell ID and a user-specific sequence group frequency hopping enable indication. When there are user equipments requiring inter-cell orthogonality, the base stations of different cells allocate the same virtual cell ID and user-specific sequence group frequency hopping enable indication to the user equipment requiring inter-cell orthogonality.

[0082] Step 202: After receiving the parameters notified by the base station, the user equipment calculates the user-specific sequence group number according to the virtual cell ID and the user-specific sequence group frequency hopping enable indication, and the user equipment uses the user-specific sequence group number to send uplink control information.

[0083] In this way, user equipment requiring inter...

Abstract

The invention relates to a physical uplink control channel resource allocation method and system. The method comprises the following steps: a base issues parameters or newly added bits aiming at a user device and used for determining the physical uplink control channel resource allocation to the user device; and the user device receives the parameters or the newly added bits and determines the physical uplink control channel resource allocation according to the parameters or the newly added bits. By adopting the method and the system, provided by the invention, a physical uplink control channel can flexibly and easily realize the resource allocation of the physical uplink control channel.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a physical uplink control channel (PUCCH, Physical Uplink Control Channel) resource configuration method and system. Background technique [0002] The uplink physical channels of the long-term evolution system (LTE, Long Term Evolution) include a physical random access channel (PRACH, Physical Random Access Channel), a physical shared channel (PUSCH, Physical uplink shared channel), a physical uplink control channel (PUCCH, Physical Uplink Control Channel). [0003] In the LTE R8 / R9 / R10 protocol version, the PUCCH channel format can be divided into three categories, a total of seven types: the first category includes three formats, namely format1, format1a, and format1b, and the second category also includes three formats. Namely format2, format2a, format2b, the third category includes a format format3. The first type of PUCCH is used to transmit scheduling request (SR, Sched...
