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 present invention relates to a method and system for resource configuration of a physical uplink control channel, the method comprising: a base station issues parameters or newly added bits for determining the resource configuration of a physical uplink control channel for the user equipment to the user equipment; the user equipment The device receives the parameter or the added bit, and determines the resource configuration of the physical uplink control channel according to the parameter or the added bit. The physical uplink control channel of the present invention can flexibly and simply realize the resource allocation of the physical uplink control channel.

Description

technical field [0001] The present invention relates to the field of communication, in particular, to a resource allocation method and system for a Physical Uplink Control Channel (PUCCH, PhysicalUplink Control Channel). Background technique [0002] The uplink physical channels of the Long Term Evolution system (LTE, Long Term Evolution) include Physical Random Access Channel (PRACH, Physical Random Access Channel), Physical Shared Channel (PUSCH, Physical uplinkshared channel), Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) 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...
