Problems solved by technology

However, in this case, if the use of resources has been stable, the advantages of scheduling flexibility cannot be taken advantage of, and in typical frequency selective fading channels, there will be a situation in the deep fading interval for a long time, resulting in communication increase in difficulty
[0006] Therefore, it is currently impossible to realize the stability of the service and the frequency diversity gain brought about by frequency hopping

Embodiment 1

[0033] In this embodiment, a method for transmitting frequency hopping signaling based on semi-stable scheduling is provided.

[0034] Such as figure 2 As shown, the method for transmitting frequency hopping signaling according to this embodiment includes: step S202, the base station pre-assigns (predefined) frequency hopping parameters for the user, and the user performs frequency hopping transmission according to the frequency hopping parameters; step S204, when the user requests During scheduling, users use pre-allocated frequency hopping parameters or use new frequency hopping parameters allocated by the base station for frequency hopping transmission.

[0035] Preferably, in figure 2 On the basis of the above processing shown, the following processing may be further included: when the base station detects that the user has no data transmission, or the user requests not to transmit data, the user stops frequency hopping.

[0036]Wherein in step 202, the base station ma...

Embodiment 2

[0049] In this embodiment, a frequency hopping mode and a scheduling signaling configuration method are provided.

[0050] The method includes the following processing: when all or part of the frequency hopping users in the system use different frequency bandwidths: the users adopt the group frequency hopping mode, and the scheduling signaling is configured as single-user scheduling signaling; or the users adopt multi-granularity frequency hopping mode, the scheduling signaling is configured as group scheduling signaling; and when all or part of the frequency hopping users in the system use the same frequency bandwidth: the users adopt the single-granularity frequency hopping mode.

[0051] The above various modes will be described in detail below.

[0052] 1. Group frequency hopping mode

[0053] In the group frequency hopping mode, the following processing is performed: (1) put users with different granularities into one or more virtual groups, for example, users whose freq...

Abstract

The invention discloses an emitting method of a frequency hopping signalling, comprising: the step S202, a station preallocates the frequency hopping parameter for the users, and the users performs the frequency hopping emission according to the frequency hopping parameter; the step S204, when the user requests to dispatch, the user uses the preallocated frequency hopping parameter, or uses the station to perform the frequency hopping emission for the allocated new frequency hopping parameter. In addition, the invention also discloses a frequency hopping mode and a dispatching signalling collocation method. According to the invention, the user in the district keeps in quadrature, to randomize the disturb suffered by the user, wherein the single granularity and the multi-granularity of the bandwidth always occupy the continuity of the sub-carrier, reduces the demand of the signalling.

Description

technical field [0001] The present invention relates to a frequency modulation method for uplink multi-users of a single carrier frequency division multiple access system in 3GPP LTE in the field of communication, in particular to a method for transmitting frequency hopping signaling and a method for configuring frequency hopping mode and scheduling signaling. Background technique [0002] In order to meet the needs of ever-evolving mobile communications, there are some basic requirements in the selection of uplink wireless transmission technology, such as support for scalable bandwidth, moderate PAPR / CM (peak-to-average ratio / cubic meter), and guaranteed uplink Orthogonality of transmission, etc. Since single-carrier transmission schemes (e.g., single-carrier frequency-division multiple access (SC-FDMA)) have low PAPR / CM, they can improve power efficiency and expand coverage, and thus become the current long-term evolution (LTE) uplink transmission scheme. basic candidate ...
