Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0061] In the Long Term Evolution (LTE) system of general mobile communication technology, the user equipment sends data to the base station through the uplink shared physical channel, and the base station side uses the Hybrid Automatic Repeat Request (Hybird Automatic Repeat Request, HARQ) mechanism to process the received data. Use automatic repeat request (Automatic RepeatRequest, ARQ) and cyclic redundancy check (Cyclic Redundancy Check, CRC) to ensure the bit error performance o...

Abstract

The present application discloses a PHICH group allocation method, device, and equipment, wherein the method includes: acquiring the importance of user equipment to be allocated a PHICH group; determining the first preset number corresponding to the importance of the user equipment; A preset number represents the maximum number of PHICHs used to send feedback information in the PHICH group to be allocated to the user equipment; the higher the importance, the smaller the first preset number corresponding to the importance; determine the PHICH that satisfies the first preset condition The first target PHICH group is used as the PHICH group allocated to the user equipment; the first preset condition includes: none of the PHICHs in the PHICH group is allocated to the user equipment; or, there is an allocated PHICH allocated to the user equipment in the PHICH group The user equipment to which the allocated PHICH is allocated is of the same importance as the user equipment, and the number of allocated PHICHs is less than a first preset number. Through the embodiments of the present application, the requirements of user equipments with different importance levels on the transmission power and interference performance of the PHICH group are guaranteed, and the transmission power of the PHICH group is not wasted.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a PHICH group allocation method, device and equipment. Background technique [0002] In the Hybrid Automatic Repeat Request (HARQ) mechanism, the base station side performs a cyclic redundancy check on the data sent by the user equipment, and then sends feedback information to the user equipment according to the result of the cyclic redundancy check, wherein the feedback The information is sent to the user equipment through a Physical Hybrid ARQ Indicator Channel (PHICH). In the process of sending feedback information, multiple PHICHs can be mapped to the same resource element (Resource Element, RE) set to send feedback information to the user equipment, and multiple PHICHs mapped to the same RE set form a PHICH group . Since one base station serves multiple user equipments at the same time, when the base station sends feedback information to multiple use...
