[0058] In this embodiment, the above three kinds of information cannot be transmitted in one subframe at the same time. The location convention of the VRB used by each type of information is as follows:

[0059] The starting position of the VRB used by the first information is the fixed position #s, that is to say, assuming that the number of RBs used to transmit the first information is k, then its physical resource position in the frequency domain is VRB#s, #s+1,. .., the frequency domain position where the physical resource block corresponding to #s+k-1 is located. Preferably, s is equal to the start index value of the segment VRB, such as #0.

[0079] In this embodiment, the above three kinds of information can be transmitted in one subframe at the same time, and it is also applicable to the situation that the information cannot be transmitted in one subframe at the same time. The location convention of the VRB used by each type of information is as follows:

[0080] The starting position of the VRB used by the first information is the fixed position #s, that is to say, assuming that the number of RBs used to transmit the first information is k, then its physical resource position in the frequency domain is VRB#s, #s+1,. .., the frequency domain position where the physical resource block corresponding to #s+k-1 is located.

[0098] This embodiment can be applied to two scenarios in which D-BCH information, RACH feedback information and Paging information can be simultaneously transmitted in one subframe, or cannot be simultaneously transmitted in one subframe. The location convention of the VRB used by each type of information is as follows:

[0099] The starting position of the VRB used by D-BCH information is fixed position #s, that is to say, assuming that the number of RBs used to transmit D-BCH information is k, its frequency domain physical resource position is VRB#s, #s+1 , ..., the frequency domain position where the physical resource block corresponding to #s+k-1 is located. Preferably, s is equal to the start index value of the segment VRB, such as #0. k can be 5.

Abstract

An information transmitting method is used for the one or combined transmission(s) of three information namely a dynamic broadcast channel namely a D-BCH information, a random access channel namely an RACH feedback information and a paging channel namely a Paging information, wherein a transmitting terminal and a receiving terminal are used for transmitting a fixed virtual source block namely VRBwith the continuous index number and the starting index value and / or the terminating index value, and the position of VRB is appointing which is used by the information transmitted on each condition according to the transmitting condition of the three information; when the transmitting terminal transmits one or the combination of the three information, the corresponding VRB is distributed according to the appointed VRB position for the transmitted information, to determine the number of the VRN used by the transmitted information and indicate in the resource indication information. The invention has smaller signalling cost and satisfies the resource indication of the coexistence of the three information.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a physical resource representation method. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) project is an evolution of 3G (3rd Generation, third-generation mobile communication) technology, which improves and enhances the 3G air access technology. Among the many physical layer transmission technologies, Orthogonal Frequency Division Multiplexing (OFDM) technology has become a promising one among all downlink schemes due to its high spectrum utilization rate and low processing complexity. Kind, wherein the frame structure of LTE system FDD (Frequency Division Duplex, frequency division duplex) model is as follows figure 1 As shown, in this frame structure, a 10ms wireless frame is divided into two half-frames, each half-frame is divided into 10 time slots with a length of 0.5ms, and two time slots form a subframe with a length of 1ms. A frame i...
